    Study Notes

    Homeostasis and Kidney Function

    • The kidneys play a crucial role in maintaining homeostasis by regulating the composition and volume of extracellular fluid (ECF).
    • They excrete excess water and solutes, while conserving them during deficits.
    • Kidneys also regulate acid-base balance and eliminate metabolic wastes.
    • Blood pressure regulation is a key function of the kidneys.

    Chronic Kidney Disease (CKD)

    • Gradual loss of kidney function is characterized as CKD.
    • CKD can progress to end-stage renal disease (ESRD), the final, irreversible stage.
    • Both primary kidney disorders (e.g., glomerulonephritis) and systemic diseases (e.g., diabetes mellitus) can impact renal function.

    Prevalence of CKD and ESRD

    • Approximately 37 million adults in the US are estimated to have CKD, with most cases undiagnosed.
    • In 2018, there were 124,500 new cases of registered ESRD, showing a slight decrease compared to the previous year.
    • The rate of new ESRD cases has been declining, possibly due to improved prevention or postponement of kidney failure.
    • Despite this, the prevalence of ESRD continues to rise, reaching 746,557 in 2018.

    Impact of Vascular Disorders on Renal Function

    • Renal function depends on adequate blood supply for cell metabolism and proper function, particularly within the nephrons.
    • Hypertension (HTN) can cause arteriosclerotic lesions in the renal arterioles and glomerular capillaries.
    • This leads to decreased glomerular filtration rate (GFR), affecting tubular function and resulting in proteinuria and microscopic hematuria.
    • HTN is associated with approximately 15% of deaths attributed to renal failure.

    Pathophysiology of CKD

    • The pathophysiology of CKD varies based on the underlying disease process, and involves gradual destruction of nephron units.
    • In early stages, remaining functional nephrons hypertrophy to compensate for lost nephrons, leading to increased glomerular capillary flow and pressure.
    • This increased demand predisposes remaining nephrons to glomerular sclerosis, resulting in their eventual destruction.
    • Proteinuria from glomerular damage further contributes to tubular injury.
    • This process of nephron loss can persist even after the initial disease process resolves.

    Diabetic Nephropathy

    • High blood sugar in diabetics causes an initial increase in blood flow to the glomerulus (hyperfiltration).
    • Overwork damages the glomerulus, leading to thickening and scarring (sclerosis).
    • Nephrons are destroyed, decreasing GFR.

    Hypertensive Nephrosclerosis

    • Prolonged high blood pressure causes hardening (sclerosis) and narrowing of small renal arteries and arterioles.
    • Renal blood flow is reduced, causing lack of oxygen (ischemia) and destruction of glomeruli.
    • Tubules in the kidney begin to atrophy.

    Chronic Glomerulonephritis

    • Chronic inflammation occurs in the kidney's filtering units (glomeruli) and surrounding structures.
    • Inflammation damages renal tubules and capillaries.
    • Impaired filtering, secretion, and reabsorption processes eventually lead to loss of nephrons.

    Chronic Pyelonephritis

    • Chronic infection, often linked to obstructions, neurologic issues and vesicoureteral reflux.
    • Infection and reflux cause scarring and deformation of the kidney's inner structures.
    • Intrarenal reflux and kidney damage occur.

    Polycystic Kidney Disease

    • Genetic mutation leads to cysts forming in both kidneys.
    • Cysts compress normal kidney tissue, reducing blood flow.
    • Vascular remodeling occurs as inflammatory mediators are released damaging the tissue.

    Systemic Lupus Erythematosus (SLE)

    • An autoimmune disorder where immune complexes attack kidney tissues.
    • Immune complexes deposit in the capillary basement membrane triggering inflammation and sclerosis.
    • Can lead to various patterns of glomerulonephritis, from localized to widespread damage.

    Chronic Kidney Disease Progression

    • CKD progression varies significantly, ranging from months to years.
    • Early stage, known as decreased renal reserve, involves unaffected nephrons compensating for lost ones.
    • GFR is approximately 50% of normal, with no symptoms and normal BUN and creatinine levels.
    • As the disease advances, GFR declines further, potentially leading to hypertension and renal insufficiency symptoms.
    • Additional kidney insults, such as infection, dehydration, nephrotoxins, or urinary tract obstruction, can accelerate function decline and trigger renal failure or uremia.
    • In advanced stages, serum creatinine and BUN rise sharply, oliguria develops, and uremia symptoms become apparent.
    • End-stage renal disease (ESRD) occurs when GFR drops below 10-15% of normal, necessitating renal replacement therapy for survival.

    Chronic Kidney Disease (CKD) Stages

    • CKD stages are categorized by Glomerular Filtration Rate (GFR) and associated symptoms.

    • Stage 1: Kidney Damage with Normal or Increased GFR

      • GFR is normal or slightly increased.
      • No noticeable symptoms.
      • Blood Urea Nitrogen (BUN) and creatinine levels are normal.

    • Stage 2: Mildly Decreased GFR

      • GFR is mildly decreased.
      • Usually asymptomatic.
      • Possible hypertension (HTN).
      • Bloodwork remains generally within normal limits.

    • Stage 3: Moderate GFR Decrease

      • GFR is moderately reduced.
      • HTN, possible anemia, fatigue, anorexia, malnutrition, and bone pain may occur.
      • BUN and serum creatinine levels show slight elevation.

    • Stage 4: Severely Decreased GFR

      • GFR is severely reduced.
      • HTN, anemia, malnutrition, and altered bone metabolism become more pronounced.
      • Edema, metabolic acidosis, hypercalcemia, and possible uremia.
      • BUN and creatinine levels are significantly elevated (azotemia).

    • Stage 5: End-Stage Renal Disease (ESRD)

      • GFR is very low or absent (kidney failure).
      • Kidney failure with azotemia (high nitrogen in the blood) and overt uremia.
      • Requires renal replacement therapy (dialysis or transplantation).

    CKD & ESRD

    • An estimated 37 million American adults have CKD, the precursor to ESRD.
    • Millions more Americans are at increased risk of CKD.
    • Kidney disease is the ninth leading cause of death in the United States.
    • African Americans are more affected by CKD than other ethnicities.
    • Older adults experience the fastest rise in ESRD incidence.
    • Patients on dialysis often face job loss, time-consuming treatment regimens, and family breakdown.
    • CKD often involves widespread damage to both kidneys, leading to progressive scarring.

    Leading Causes of ESRD

    • Diabetes is the primary cause of ESRD in all population groups in the United States.
    • Hypertension is a close second to diabetes as a major cause of ESRD.
    • Many patients with ESRD have both diabetes and hypertension.

    African Americans and Kidney Disease

    • African Americans in the United States have significantly higher rates of End-Stage Renal Disease (ESRD) compared to other racial and ethnic groups.
    • This disparity is attributed to several factors, including:
      • Higher prevalence of CKD risk factors among African Americans.
      • Limited access to and receipt of quality healthcare.
      • Unique health beliefs and practices within the African American community.
      • Influence of social determinants of health on access and outcomes.
    • African Americans are nearly three times more likely to develop treated ESRD compared to their white counterparts.
    • Considering that African Americans represent approximately 13% of the US population, these figures are significant.
    • Diabetes and high blood pressure account for a majority (70%) of new kidney disease cases.
    • Nurses working with Black patients diagnosed with high blood pressure or diabetes should provide patient education at every healthcare visit.

    Prevention Strategies

    • Aggressive management of chronic diseases, particularly diabetes and hypertension, is crucial for preventing both ESRD and CKD.
    • Patients are advised to follow these preventative measures:
      • Adhere to a low-sodium diet.
      • Engage in regular exercise.
      • Attend scheduled healthcare appointments.
      • Refrain from smoking.
      • Limit alcohol consumption.

    Clinical Manifestations of CKD

    • CKD often goes undetected until the late stage of ESRD (End-Stage Renal Disease)
    • Uremia refers to the syndrome of symptoms that occur in ESRD, resulting from metabolic waste accumulation in the blood
    • Uremia disrupts fluid and electrolyte balance, impairs kidney regulation and endocrine functions, and affects multiple organ systems
    • Early uremia symptoms often mimic viral infections or flu, causing misdiagnosis
    • Symptoms like nausea, apathy, weakness and fatigue are typically ignored until they worsen
    • As uremia progresses, symptoms intensify, including frequent vomiting, increasing weakness, lethargy, and confusion

    Uremia

    • Characterized by increased BUN and creatinine levels, leading to waste product buildup in the blood.
    • Clinical Manifestations:
      • Cardiovascular: Hypertension, edema, coronary heart disease, heart failure.
      • Respiratory: Pulmonary edema, pleuritis, Kussmaul inspirations.
      • Gastrointestinal: Anorexia, nausea, vomiting, gastroenteritis, hiccups, abdominal pain, peptic ulcer, GI bleeding, uremic fetor.
      • Musculoskeletal: Osteodystrophy, bone pain, spontaneous fractures.
      • Neurological: Apathy, lethargy, headache, impaired cognition, insomnia, restless leg syndrome, gait disturbances.
      • Hematologic: Anemias, impaired clotting, pallor, uremic skin color, dry skin, poor skin turgor, pruritus.
      • Metabolic: Hyperparathyroidism, glucose intolerance, proteinuria, hematuria, fixed specific gravity, nocturia, oliguria.
    • Clinical Therapies:
      • Monitoring: Serum electrolytes, BUN, creatinine, ABGs (pH), lipid levels. Cardiorespiratory monitoring and accurate I&O.
      • Management: Diuretic administration, fluid restriction, dietary consult for improved nutrition status.
      • Dialysis: Often the only option for treating uremia.

    Anemia

    • Occurs due to decreased production of red blood cells in the kidneys.
    • Clinical Manifestations: Fatigue, pallor, dizziness, confusion, lethargy, tachycardia, tachypnea, hypotension.
    • Clinical Therapies:
      • Iron supplementation: To correct iron deficiency.
      • Epoetin administration: To stimulate red blood cell production.
      • Blood transfusion: Transfusion of red blood cells in severe cases.
      • Addressing the underlying cause: Treatments for renal failure.

    Fluid Volume Excess

    • Results from compromised kidney function, leading to fluid retention.
    • Clinical Manifestations: Dependent pitting edema, respiratory crackles, dyspnea, pulmonary edema, hypoxemia, weight gain, tachycardia, jugular vein distention.
    • Clinical Therapies:
      • Fluid restriction: To limit further fluid accumulation.
      • Sodium-restricted diet: To decrease fluid retention.
      • Diuretics: To promote fluid excretion.
      • Dialysis: For severe cases of fluid overload.

    Hyperkalemia

    • Increased potassium levels in the blood due to impaired kidney function.
    • Clinical Manifestations: Ventricular arrhythmias, tall peaked T waves, widened QRS, cardiac arrest, smooth muscle hyperactivity, nausea, vomiting, abdominal cramping, diarrhea, muscle weakness, paresthesias, flaccid paralysis.
    • Clinical Therapies:
      • Potassium removal: Removing potassium from IV solutions.
      • Low-potassium diet: To limit potassium intake.
      • Glucose and insulin administration: To move potassium from the blood into the cells.
      • Potassium-absorbing enema solutions: To remove potassium from the colon.
      • Dialysis: For severe or uncontrolled hyperkalemia.

    ### Fluid and Electrolyte Effects of CKD

    • Early-stage CKD leads to proteinuria, hematuria, and decreased urine concentration ability due to impaired filtration and reabsorption.
    • Reduced urine concentration ability results in poor salt and water conservation, increasing dehydration risk.
    • Polyuria, nocturia, and fixed specific gravity (1.008 to 1.012) are common in early-stage CKD.
    • As GFR decreases, sodium and water retention occur, requiring restrictions.
    • Hyperkalemia develops as renal failure progresses, with symptoms like muscle weakness, paresthesias, and ECG changes appearing when GFR falls below 5 mL/min.
    • Impaired phosphate excretion leads to hyperphosphatemia and hypocalcemia, further exacerbated by reduced calcium absorption due to impaired vitamin D activation.
    • Advanced renal failure causes hypermagnesemia, necessitating avoidance of magnesium-containing antacids.
    • Impaired hydrogen ion excretion and buffer production in advanced renal failure leads to metabolic acidosis.
    • Kussmaul respirations (increased respiratory rate and depth) compensate for metabolic acidosis.
    • Metabolic acidosis can be asymptomatic but may present as general malaise, weakness, headache, nausea, vomiting, and abdominal pain.

    Cardiovascular Effects of ESRD

    • Accelerated atherosclerosis is a common cause of death in ESRD.
    • Contributing factors: HTN, hyperlipidemia, glucose intolerance.
    • Cerebral and peripheral vascular manifestations of atherosclerosis are also common.
    • Systemic HTN is a common complication of ESRD.
    • Causes of HTN in ESRD: Excess fluid volume, increased renin-angiotensin activity, increased peripheral vascular resistance, and decreased prostaglandins.
    • Other consequences of fluid overload: Edema and heart failure.
    • Pulmonary edema: Can result from heart failure and increased permeability of the alveolar capillary membrane.
    • Pericarditis: Retained metabolic toxins can irritate the pericardial sac, causing inflammation.
    • Cardiac tamponade: A potential complication of pericarditis where inflammatory fluid in the pericardial sac interferes with ventricular filling and cardiac output.
    • Early dialysis: Has reduced the incidence of pericarditis.

    Hematologic Effects

    • Anemia is a common complication of uremia, caused by multiple factors including decreased erythropoietin production by the kidneys.

    • Uremic toxins suppress red blood cell (RBC) production and shorten RBC lifespan.

    • Nutritional deficiencies in iron and folate, as well as increased risk of gastrointestinal bleeding, contribute to anemia.

    • Anemia can lead to fatigue, weakness, depression, impaired cognition, and cardiovascular complications, including heart failure in end-stage renal disease (ESRD).

    • Renal failure impairs platelet function, increasing the risk of bleeding disorders like epistaxis and gastrointestinal bleeding.

    Immune System Effects

    • Uremia elevates the risk of infections.

    • High levels of urea and metabolic wastes impair various aspects of inflammation and immune function, impacting white blood cell (WBC) count, humoral and cell-mediated immunity, and phagocyte function.

    • Both the acute inflammatory response and delayed hypersensitivity responses are affected.

    • Fever is suppressed, often delaying infection diagnosis.

    Gastrointestinal Effects

    • Anorexia, nausea, and vomiting are common early symptoms of uremia.
    • Hiccups and gastroenteritis are also common.
    • Ulcerations can affect any part of the GI tract, increasing the risk of bleeding.
    • Peptic ulcer disease is particularly common in patients with uremia.
    • Uremic fetor (a urine-like breath odor with a metallic taste) can contribute to anorexia.

    Neurologic Effects

    • Uremia affects both the central and peripheral nervous systems.
    • Early CNS symptoms include cognitive changes like difficulty concentrating, fatigue, and insomnia.
    • Advanced uremia can lead to psychotic symptoms, seizures, and coma.
    • Peripheral neuropathy is also common in advanced uremia, affecting both sensory and motor nerves.
    • Lower limbs are initially affected, leading to restless leg syndrome and paresthesia (numbness or tingling).
    • As uremia progresses, motor function deteriorates, causing muscle weakness, decreased reflexes, and gait disturbances.

    Musculoskeletal Effects

    • Hyperphosphatemia and hypocalcemia stimulate parathyroid hormone secretion, increasing calcium resorption from bone.
    • Osteoblast and osteoclast activity is also affected, leading to bone resorption and remodeling.
    • Decreased vitamin D synthesis and calcium absorption contribute to renal osteodystrophy, also called renal rickets.
    • Osteodystrophy involves osteomalacia (bone softening) and osteoporosis (decreased bone mass), potentially leading to bone cysts.
    • Manifestations include bone tenderness, pain, and muscle weakness, increasing the risk of spontaneous fractures in patients with osteodystrophy.

    Endocrine and Metabolic Effects

    • Uremia is characterized by elevated serum creatinine and BUN levels.
    • Uric acid levels increase, raising the risk of gout.
    • Insulin resistance develops in uremia, leading to glucose intolerance.
    • High triglyceride levels and low high-density lipoprotein levels contribute to accelerated atherosclerosis.
    • CKD affects reproductive function, with pregnancies rarely carried to term and menstrual irregularities being common.
    • Reduced testosterone levels, low sperm counts, and impotence impact males with ESRD.

    Dermatologic Effects

    • Anemia and retained pigmented metabolites result in pallor and a yellowish skin hue.
    • Dry skin with poor turgor arises from dehydration and sweat gland atrophy.
    • Bruising and excoriations are frequent occurrences.
    • Metabolic wastes deposited in the skin contribute to itching or pruritus.
    • Uremic frost, characterized by crystallized urea deposits on the skin, can occur in advanced uremia.

    Early Management of CKD

    • Focuses on eliminating factors that worsen renal function.
    • Implements measures to slow progression of CKD to ESRD.

    Treatment Goals

    • Maintain nutritional status while minimizing waste accumulation and uremia.
    • Identify and treat CKD complications.
    • Prepare for renal replacement therapies like dialysis or transplantation.

    Diagnostic Tests

    • Used to identify and monitor CKD.
    • Tests include urinalysis, BUN, serum creatinine, creatinine clearance, serum electrolytes, CBC, renal ultrasonography and kidney biopsy.

    Urinalysis

    • Measures urine specific gravity and detects abnormal urine components.
    • CKD can cause fixed specific gravity at 1.010 due to impaired tubular function.
    • Abnormal proteins, blood cells, and cellular casts may be present.
    • Urine culture identifies urinary tract infections which can worsen CKD.

    BUN and Serum Creatinine

    • Evaluate kidney function in eliminating nitrogenous waste products.
    • Levels monitor progression of renal failure.
    • 25-50 mg/dL BUN indicates mild azotemia.
    • BUN exceeding 100 mg/dL suggests severe renal impairment.
    • Uremia symptoms appear at around 200 mg/dL BUN.
    • Serum creatinine exceeding 4 mg/dL indicates serious renal impairment.

    Creatinine Clearance

    • Assesses Glomerular Filtration Rate (GFR) and renal function.
    • In early CKD, GFR is >20% of normal, creatinine clearance ≥30 mL/min.
    • As disease progresses, GFR <20% of normal, creatinine clearance 15-29 mL/min.
    • In ESRD, GFR <10-15% of normal, creatinine clearance <15 mL/min.

    Serum Electrolytes

    • Levels are monitored throughout CKD.
    • Sodium may be normal or low due to water retention.
    • Potassium is elevated, usually under 6.5 mEq/L.
    • Phosphate is elevated, calcium level is decreased.
    • Metabolic acidosis is identified by low pH, low pCO2, and low bicarbonate.
    • CBC reveals moderate anemia, hematocrit (20-30%), low hemoglobin, reduced RBCs and platelets.

    Renal Ultrasonography

    • Evaluates kidney size.
    • In CKD, kidney size decreases due to nephron destruction and reduced mass.

    Kidney Biopsy

    • Identifies the underlying disease process if unclear.
    • Differentiates acute from chronic kidney disease.
    • Performed surgically or percutaneously.

    CKD & Drug Therapy

    • CKD impacts drug therapy's pharmacokinetics and pharmacodynamics.
    • Most medications are eliminated primarily through the kidneys.
    • The half-life and plasma levels of many medications increase with CKD.
    • Phosphate-binding drugs are used to lower high phosphate levels in the blood of CKD patients.
    • These phosphate-binding drugs can affect the absorption of other medications if taken concurrently.
    • Proteinuria can reduce plasma protein levels, potentially leading to drug toxicity, especially with highly protein-bound drugs.
    • Nephrotoxic drugs should be used cautiously in patients with CKD.
    • Examples of nephrotoxic drugs:
      • Amoxicillin, ampicillin, dicloxacillin, penicillin G benzathine, penicillin V potassium (antibiotics)
      • Indomethacin (NSAID)
      • Cyclosporine, cisplatin (chemotherapy drugs)
      • Amphotericin B (antifungal)
      • Aminoglycoside antibiotics (amikacin, gentamicin, neomycin, tobramycin)
    • Avoid drugs eliminated by the kidney:
      • Meperidine (narcotic)
      • Metformin (antidiabetic)
    • Furosemide or loop diuretics are used to reduce excess fluid volume and edema.
    • Diuretic therapy can lower blood pressure and cause potassium loss, leading to low potassium levels.
    • Antihypertensive agents are used to manage blood pressure, slow renal failure progression, and prevent heart and brain complications.
    • ACE inhibitors are preferred, but any class of antihypertensive medication might be prescribed.
    • Medications can be used to manage electrolyte imbalances and acidosis.
      • Sodium bicarbonate can correct mild acidosis.
      • Oral phosphorus-binding agents (calcium acetate) lower serum phosphate and normalize calcium levels.
      • Vitamin D supplements improve calcium absorption.
      • High potassium levels are treated with:
        • Intravenous insulin and glucose to move potassium into cells.
        • SPS (potassium-ion exchange resin) orally or rectally (enema).
    • Folic acid and iron supplements are prescribed to address anemia associated with CKD.
    • Multivitamins are often prescribed due to potential nutrient deficiencies caused by anorexia, nausea, and dietary restrictions.

    Nutrition and Fluid Management in CKD

    • With declining renal function, the body struggles to eliminate water, solutes, and metabolic wastes, leading to their accumulation and causing uremic symptoms.
    • Early dietary modifications can slow down kidney damage, lessen uremic symptoms, and prevent complications.
    • The body cannot store excess proteins, which are broken down into urea and other nitrogenous wastes, putting a further strain on the kidneys.
    • Protein-rich foods contain inorganic ions (hydrogen, phosphate, sulfites) that also need to be eliminated by the kidneys.
    • Restricting protein intake is beneficial for CKD patients:
      • Aim for 0.6 g/kg of body weight per day (around 40 g/day).
      • Prioritize high biological value proteins, abundant in essential amino acids.
      • Animal sources like meat, poultry, fish, eggs, milk, cheese, and yogurt provide high-quality proteins.
    • Increase carbohydrate intake to meet energy needs, aiming for around 35 kcal/kg per day.
    • Carefully regulate water and sodium to maintain normal ECF volume.
      • Generally, 1 to 2 L of water per day is recommended.
      • Limit sodium intake to 2 g/day initially, with stricter restrictions potentially required as renal failure progresses.
      • Instruct patients to monitor their weight daily and report any gain exceeding 5 lb over two days.
    • In later stages of CKD, potassium and phosphorus intake also needs to be restricted.
      • Limit potassium to less than 60-70 mEq/day (normal intake is around 100 mEq/day).
      • Advise against using salt substitutes, which often contain high levels of potassium chloride.
      • Foods high in phosphorus include eggs, dairy products, and meat.

    Renal Replacement Therapy

    • Renal replacement therapy, like dialysis or kidney transplantation, is considered when pharmacologic and dietary management strategies are no longer effective for managing fluid and electrolyte balance and preventing uremia.
    • Hemodialysis performed in a dialysis center is the most common therapy for end-stage renal disease (ESRD) in the United States, followed by peritoneal dialysis and kidney transplant.
    • The choice of renal replacement therapy is influenced by the patient's age, concurrent health problems, donor availability, and personal preferences.
    • Planning ahead for vascular access for hemodialysis before dialysis is necessary, as establishing vascular access can take several months.
    • Starting patient instruction before hemodialysis treatments are required can result in more effective learning, especially when treatments will be performed at home.
    • If a family member will be assisting with dialysis, training should begin before the onset of uremia.
    • Tissue typing and identification of potential living related donors should be done before the onset of ESRD if transplantation is being considered.
    • Both the patient and potential donor should understand the risks, benefits, and options available to make informed decisions.
    • If a decision for transplantation is made early, dialysis can potentially be avoided.

    Dialysis

    • Both hemodialysis and peritoneal dialysis can be performed at home, although few patients use home hemodialysis.
    • Hemodialysis for ESRD is typically done three times a week for a total of 9 to 12 hours.

    Kidney Transplantation

    • Kidney transplantation is the most successful organ transplantation procedure.
    • The first kidney transplant was performed in 1954, using identical twins.
    • The primary limitation for kidney transplantation is the availability of organs.
    • In 2019, 39,718 kidney transplantations were performed.
    • There are currently over 112,000 people on the waiting list for a kidney transplant.
    • Kidney transplantation improves survival and quality of life for patients with ESRD.
    • Transplant recipients are more likely to survive than patients on dialysis.
    • At 5 years, 90% of transplant recipients survive compared to 33% surviving on dialysis.
    • Kidneys are obtained from both living and deceased donors.
    • 7,397 kidneys came from live donors in 2019.
    • Over 11,870 kidneys came from deceased donors in 2019.
    • Deceased donors can donate two kidneys.
    • Quality of life improves significantly after transplantation.
    • Dietary and fluid restrictions are reduced after transplantation.
    • A close match between blood and tissue type is desired for both deceased and living-donor transplants.
    • Human leukocyte antigens are used to assess compatibility, and six antigens in common is considered a "perfect" match.
    • Living-donor transplants have higher success rates than deceased-donor transplants.
    • The 1-year graft survival rate is 95.1% for living-donor transplants compared to 89% for deceased-donor transplants.
    • People with normal kidneys who are in good health can donate a kidney.
    • The majority of living donors are siblings or spouses.
    • Predonation counseling is essential.
    • Nephrectomy (kidney removal) is major surgery and carries potential risks.
    • Trauma or disease could affect the remaining kidney after donation.
    • The psychological impact on the donor can be significant if the transplant fails.
    • Deceased-donor kidneys are obtained from individuals meeting specific criteria.
    • Criteria include brain death, age under 65, and no significant systemic disease, malignancy or infection.
    • Kidneys are removed after brain death is determined and preserved by hypothermia or continuous hypothermic pulsatile perfusion.
    • Kidneys preserved by hypothermia must be transplanted within 24 to 48 hours.
    • Continuous hypothermic pulsatile perfusion allows for transplantation up to 3 days later.
    • The donor kidney is placed in the recipient's lower abdominal cavity.
    • The renal artery, vein, and ureter are connected to the recipient's circulatory system.
    • The renal artery is connected to the hypogastric artery, and the renal vein is connected to the iliac vein.
    • The ureter is connected to the recipient's bladder using a tunnel technique to prevent reflux.

    Deceased Donor Allocation

    Organ Transplantation

    • Grafted organs stimulate an immune response to reject the transplant, unless the donor and recipient are identical twins.
    • Immunosuppressive drugs are used to minimize immune rejection.
    • Common immunosuppressants include azathioprine, mycophenolate mofetil, prednisone, and cyclosporine.
    • These drugs suppress the immune system and increase the risk of infections and cancers with long-term use.
    • Glucocorticoids like prednisone and methylprednisolone are used for maintenance immunosuppression and treating acute rejection.
    • Long-term corticosteroid use has side effects such as impaired wound healing, emotional disturbances, osteoporosis, and Cushingoid effects on metabolism.
    • Cyclosporine primarily affects cellular immunity, particularly helper T cells.
    • Cyclosporine has adverse effects like hepatotoxicity, hirsutism, and nephrotoxicity.

    Kidney Transplantation

    • Even with immunosuppressive therapy, kidney rejection can occur at any time.
    • Acute rejection develops within months of transplantation, caused by T-lymphocyte proliferation.
    • Acute rejection may present with elevated serum creatinine and oliguria.
    • Methylprednisolone and OKT3 monoclonal antibody are used to manage acute rejection episodes.
    • OKT3 can produce severe systemic reactions such as chills, fever, hypotension, headache, and pulmonary edema.
    • Chronic rejection, which can develop months to years after transplantation, is a major cause of graft loss.
    • Chronic rejection involves both humoral and cellular immune responses.
    • Chronic rejection does not respond to increased immunosuppression.
    • Chronic rejection presents with progressive azotemia, proteinuria, and HTN.
    • Hypertension can complicate kidney transplantation due to graft rejection, renal artery stenosis, or renal vasoconstriction.
    • Patients may develop glomerular lesions and nephrosis.
    • HTN and altered blood lipids increase the risk of death from myocardial infarction and stroke after transplantation.

    Long-Term Immunosuppression

    • Infection is a constant threat with long-term immunosuppression.
    • Bacterial, viral, and fungal infections can develop, affecting the blood, lungs, and CNS.
    • Tumors are common, including carcinoma in situ of the cervix, lymphomas, and skin cancers.
    • The risk of congenital anomalies is increased in infants of mothers who underwent immunosuppressive therapy.
    • Corticosteroid use can lead to bone problems, GI disorders, and cataract formation.

    Complementary Health Approaches for CKD Patients

    • Herbal supplements should be avoided as they may contain minerals that are harmful to the kidneys.

    • Over-the-counter and complementary health approaches should be discussed with healthcare providers (HCP).

    • Dietary changes can contribute to kidney health.

      • Foods that can improve kidney function: Sprouts, garlic, legumes, beans, potato, banana, papaya, watermelon, yogurt, green vegetables, and whole grains.

      • Cranberry juice (unsweetened) maintains urine acidity.

    • Palliative care offers emotional support for patients and families, and provides therapies such as massages and relaxation techniques.

    • Spiritual support can be beneficial.

    Lifespan Considerations for CKD in Children and Adolescents

    • Leading causes of kidney failure in children vary by age:
      • Birth to 4 years: Birth defects and hereditary diseases are the most common causes.
      • 5 to 14 years: Hereditary diseases, nephrotic syndrome, and systemic diseases are the leading causes.
    • Treatment for kidney disease in children and adolescents is tailored to the cause:
      • Pediatric nephrologist referral: Children may be referred to a specialized pediatric nephrologist for treatment.
      • Blood pressure management: Medications may be necessary to manage high blood pressure, which can help slow the progression of kidney disease.
    • Addressing complications of declining kidney function:
      • Anemia: Treatment includes erythropoietin, a hormone that stimulates red blood cell production.
      • Growth failure: Dietary changes, food supplements, and growth hormone injections may be necessary.
    • Treatment for kidney failure:
      • Dialysis: A process that filters the blood when the kidneys are unable to function properly.
      • Transplantation: A surgical procedure to replace the failing kidneys with a healthy donor kidney.

    CKD and Pregnancy Complications

    • The rate of preterm delivery is significantly higher in women with CKD (16.3%) compared to the general population (1.2%).
    • There is a notable increase in preeclampsia rates among women with CKD (40.1%) compared to the general population (2.9%).
    • Neonatal death rates are higher in newborns of mothers with CKD (2.1%) compared to mothers with normal renal function (0.2%).
    • The frequency of small-for-gestational-age neonates is significantly higher in women with CKD (33.9%) compared to women without CKD (9.3%).

    Management of Pregnancy in CKD

    • Maintaining normal serum albumin levels throughout pregnancy is crucial for fetal growth.
    • Effective blood pressure control is essential to prevent further kidney damage and maintain fetal and placental circulation.
    • Pregnant women with CKD may require multiple medications to manage chronic hypertension.
    • Dialysis frequency may need to increase to at least five times per week during pregnancy.
    • Anemia management is particularly important in pregnant women with CKD, with higher doses of iron and erythropoietin replacement potentially reducing preterm birth risk.
    • Despite rigorous interventions, preeclampsia remains a common occurrence in pregnant women with CKD.

    Preeclampsia and Long-Term Effects

    • Researchers suggest a possible link between preeclampsia and the development of CKD.
    • Preeclampsia may have long-term effects beyond the pregnancy, increasing the risk of hypertension, ischemic heart disease, and cardiovascular death.
    • Low birth weight and preterm delivery are associated with an increased risk of CKD.
    • Subsequent pregnancies after preeclampsia carry a higher risk of developing CKD, especially when preeclampsia occurs later in pregnancy.

    CKD in Older Adults

    • CKD is prevalent in older adults, negatively impacting quality of life and potentially fatal.
    • In most cases, older adults can manage CKD with their primary care physician.
    • Some cases necessitate consultation with nephrology and geriatric specialists, especially with new onset of urinary abnormalities, rapid kidney function decline, systemic diseases affecting kidneys, or advanced kidney function nearing failure.
    • The aging kidney undergoes structural and functional changes.
    • Structurally, the number of nephrons decreases.
    • Functionally, glomerular filtration rate (GFR) declines, leading to reduced drug clearance.
    • Urine concentration ability diminishes, and sodium conservation becomes more difficult.
    • The kidney's ability to compensate for acid-base imbalances slows down.
    • Despite these changes, the kidney retains its capacity to regulate fluid and electrolyte balance effectively unless additional stressors occur.
    • Stressors like hypotension, nephrotoxic drugs, or inflammatory processes (e.g., glomerulonephritis) can trigger renal failure in older adults.
    • Manifestations of renal failure may be overlooked in older adults, with edema mistakenly attributed to heart failure and high blood pressure to pre-existing hypertension.
    • Serum creatinine levels rise slowly due to decreased muscle mass and creatinine production in older adults.
    • Blood urea nitrogen (BUN) levels may remain within normal limits.
    • Treatment for renal failure in older adults mirrors that used for younger individuals, including hemodialysis, peritoneal dialysis, and renal transplantation.
    • Treatment options, including conservative management or no treatment, along with potential benefits and consequences, must be explained clearly to the patient and caregivers, especially when the patient faces other health issues.

    Measures to Reduce the Risk of CKD

    • Preventing kidney disease, managing diabetes and hypertension are crucial for reducing the risk of Chronic Kidney Disease (CKD).
    • Maintain blood glucose and blood pressure within recommended ranges to reduce adverse effects on the kidneys.
    • Promote early and effective treatment for infections, especially skin and throat infections caused by streptococcal bacteria.
    • Discuss measures to reduce the risk of Urinary Tract Infections (UTIs) and emphasize the importance of prompt treatment.
    • Ensure adequate hydration, especially when nephrotoxic drugs are prescribed.
    • Encourage individuals with End-Stage Renal Disease (ESRD) to discuss with their healthcare provider options to avoid long-term dialysis.

    Communicating with Patients

    • Nurses play a key role in ensuring patients understand their CKD diagnosis.
    • Assume patients may not understand, even if they appear silent. Encourage questions.
    • Be aware of nonverbal cues.
    • Address both cognitive and emotional aspects of the diagnosis.
    • Use open-ended questions to assess understanding: "Tell me about your understanding of your CKD diagnosis. Do you have any questions about your diagnosis? I am here to help answer any questions or concerns that you may have about CKD."

    Assessment

    • Subjective Data
      • Patient interview helps gather information regarding:
        • Complaints: anorexia, nausea, weight gain, edema
        • Current treatment: dialysis type and frequency, previous kidney transplantation
        • Chronic diseases: diabetes, heart failure, kidney disease
    • Objective Data
      • Physical Examination:
        • Assess mental status, vital signs: temperature, heart and lung sounds, peripheral pulses
        • Urine output, weight
        • Skin color, moisture, condition, edema
        • Bowel tones
        • Presence and location of an AV fistula, shunt, or graft or peritoneal catheter

    Diagnosis

    • Patients with CKD may experience various problems such as:
      • Risk for inadequate renal perfusion
      • Undernutrition
      • Fluid volume excess
      • Impaired skin integrity
      • Risk for Infection
      • Disturbed body image

    Planning

    • The plan of care, developed collaboratively with the patient, may include goals like:
      • Patient will understand and verbalize their daily fluid allowance
      • Patient's weight will decrease and approach their baseline level
      • Patient will experience comfortable breathing with clear breath sounds
      • Patient will remain free of infection
      • Patient will openly share feelings about changes in body image

    Promoting Effective Tissue Perfusion

    • As the number of nephrons decrease, kidney perfusion declines, impacting fluid and electrolyte balance and waste elimination.
    • Monitor intake and output (I&O), vital signs (including orthostatic blood pressures), and weight to track fluid volume changes.
    • Restrict fluids as ordered, as the kidneys have a reduced capacity to remove excess fluid.
    • Monitor respiratory status (lung sounds) every 4-8 hours to identify potential pulmonary edema caused by fluid overload.
    • Monitor blood urea nitrogen (BUN), serum creatinine, pH, electrolytes, and complete blood count (CBC).
    • Report significant changes in these values, indicating declining renal function, metabolic acidosis, and potential electrolyte imbalances.
    • Administer antihypertensive medications as ordered to manage hypertension, a crucial factor in slowing CKD progression.

    Promoting Balanced Nutrition

    • Anorexia, nausea, and vomiting are common in end-stage renal disease (ESRD) and uremia, exacerbated by dietary restrictions.
    • Administer medications to treat electrolyte imbalances as prescribed, monitoring for both intended and adverse effects.
    • Monitor food and nutrient intake, including episodes of vomiting to assess dietary adequacy.
    • Weigh the patient daily before breakfast for accurate measurement.
    • Administer antiemetic agents 30-60 minutes before meals to reduce nausea and vomiting.
    • Provide mouth care before meals and at bedtime to enhance taste, stimulate appetite, and maintain oral health.
    • Serve small meals and provide snacks to improve food intake without triggering nausea.
    • Encourage dietary consultations, involving the patient in meal planning and allowing for preferred foods within restrictions.
    • Monitor nutritional status through weight tracking, laboratory values (serum albumin, BUN), and anthropometric measurements.
    • Administer parenteral nutrition as prescribed, carefully monitoring blood glucose levels and adhering to aseptic technique.
    • Prioritize rest periods for the patient, as anemia related to CKD may induce fatigue and activity intolerance.

    Infection Risk in CKD

    • CKD patients have weakened immune systems, increasing infection risk.
    • Dialysis procedures with invasive devices heighten infection risk.
    • Kidney transplant recipients remain on immunosuppressants, further suppressing immunity.
    • Standard precautions and hand hygiene are paramount to prevent infection.
    • Hemodialysis or multiple blood transfusions raise hepatitis B, C, and HIV risks.
    • Monitor vital signs frequently, as subtle changes may indicate infection.
    • Increased WBCs suggest bacterial infection, whereas decreased WBCs imply viral infection.
    • A shift in the differential with more immature WBCs (bands) signals infection.
    • Culture urine, dialysis fluids, and drainage as needed to identify pathogens.
    • Clear dialysate return in peritoneal dialysis is expected; cloudy dialysate implies peritonitis, requiring immediate attention.
    • Promote respiratory hygiene with position changes, coughing, and deep breathing to reduce infection risk.
    • Restrict visits from obviously ill individuals to safeguard the patient.

    Body Image in CKD

    • CKD and kidney failure can affect body image.
    • Dialysis procedures require AV fistula/shunt or peritoneal catheters, altering appearance.
    • Kidney transplantation, while restoring wholeness, leaves a scar that might impact body image.
    • Involve patients in their care to enhance acceptance and foster dialogue about treatment impacts.
    • Encourage expression of feelings and concerns without judgment to build self-worth.
    • Promote patient involvement in decision-making and self-care to enhance control and independence.
    • Support positive gains but avoid enabling denial; adaptation to loss is crucial.
    • Help patients set and achieve realistic goals to demonstrate progress.
    • Provide positive reinforcement and feedback to support growth and adaptation.

    Chronic Kidney Disease (CKD) Home Care Teaching

    • Understanding CKD and Renal Failure: Patients should be informed about the nature of their kidney disease, including expected progression and effects on their overall health.

    • Monitoring Vital Signs: Regularly monitor weight, vital signs (blood pressure, heart rate, temperature), and any changes in these measurements.

    • Dietary & Fluid Restrictions: Involve the patient, a dietitian, and a family member in setting and managing dietary and fluid restrictions. Provide strategies to manage nausea and thirst while adhering to fluid limitations.

    • Fistula or Shunt Care: Teach patients how to assess and protect a fistula or shunt for hemodialysis, including care and appropriate use of the extremity if one is anticipated.

    • Peritoneal Dialysis: Instruct on peritoneal catheter care and the procedure for peritoneal dialysis, including a family member or significant other in case the patient cannot perform the procedure independently.

    Supporting Patients with CKD

    • Coping Strategies: Reinforce effective coping strategies, encouraging positive approaches and facilitating contact with support groups for peer support.

    • Mental Health Counseling: Refer patients for mental health counseling if needed to develop effective coping and adaptation strategies.

    • Dietary Counseling: Refer patients to a dietitian for personalized diet planning and counseling.

    • Hemodialysis Training: If home hemodialysis is planned, provide formal training to the designated dialysis helper.

    • National Resources: Refer patients to the National Kidney Foundation and American Association of Kidney Patients for additional support and educational materials.

    Care for Older Adults with CKD

    • Fluid Intake: Assess fluid and nutritional intake. Encourage older adults to drink fluids even when not thirsty, addressing concerns about incontinence or nocturia.

    • Caregiver Education: Educate caregivers to make fluids readily available throughout the day and consider the older adult's preferences when providing fluids.

    Home Care Assessment for Kidney Disease

    • Several factors are essential for assessing a patient's ability to manage home dialysis.
    • Access to a dialysis center or outpatient unit is crucial for both in-person and home dialysis care.
    • Reliable transportation is necessary for accessing dialysis facilities and other related services.
    • Home hemodialysis is suitable if the patient has appropriate electrical and plumbing fixtures at home.
    • A caregiver is vital for home dialysis, they must be trained to manage the dialysis process.
    • Continuous ambulatory peritoneal dialysis (CAPD) is a potential option, requiring the patient's manual dexterity, will, and cognitive ability to manage infusions.
    • Intermittent peritoneal dialysis using a machine is an alternative if the patient lacks the necessary skills for CAPD.
    • Family members or support people can play a significant role in assisting the patient with home dialysis care.

    Chronic Kidney Disease (CKD)

    • A progressive condition involving gradual kidney function loss.
    • Characterized by the decline of the body's ability to filter waste products, maintain fluid balance, and regulate blood pressure.
    • Progresses through five stages, culminating in End-Stage Renal Disease (ESRD), requiring dialysis or kidney transplantation for survival.

    Pathophysiology of CKD

    • Nephron Destruction: Gradual loss of nephrons (functional units of the kidney) leads to:
      • Hypertrophy (enlargement) of remaining nephrons for compensation.
      • Glomerular damage and scarring (glomerular sclerosis) due to overworked nephrons.
    • Progressive Decline in GFR: Glomerular Filtration Rate (GFR), a measure of kidney function, decreases with advancing CKD.
      • GFR reduction results in metabolic waste accumulation in blood (uremia), causing symptoms and complications.
    • Fluid, Electrolyte, and Acid-Base Imbalance: Impaired kidney function leads to:
      • Difficulty in regulating fluid balance and excreting electrolytes.
      • Imbalances like hyperkalemia (high potassium), hyperphosphatemia (high phosphate), hypocalcemia (low calcium), and metabolic acidosis.
    • Hormonal Dysregulation: Impaired production of hormones:
      • Erythropoietin (stimulates red blood cell production), resulting in anemia.
      • Activated vitamin D, leading to bone disorders (renal osteodystrophy).
    • Increased Cardiovascular Risk: CKD patients have elevated cardiovascular disease risk due to:
      • Hypertension (high blood pressure).
      • Dyslipidemia (abnormal blood lipid levels).
      • Vascular calcification.
      • Cardiovascular complications are a leading cause of death in CKD.

    Management of CKD

    • Early Detection and Management:
      • Early-stage CKD often lacks symptoms, necessitating routine kidney function monitoring.
      • Monitoring is crucial for individuals with risk factors like diabetes and hypertension.
    • Interdisciplinary Care: Requires collaboration among healthcare professionals, including:
      • Nephrologists (kidney specialists).

    • Polypharmacy and Drug Dosing: Multiple medications can increase the risk of drug interactions and nephrotoxicity in older adults. Adjusting dosages to account for reduced renal clearance is essential
    • Renal Replacement Therapy: Hemodialysis or peritoneal dialysis may be challenging for some older adults due to mobility, transportation, or comorbidities. Transplantation is less common in older adults due to comorbidities or frailty
    • End-of-Life Planning: Many older adults with advanced CKD may opt for conservative management or palliative care. Nurses and healthcare providers should discuss advanced directives and end-of-life options

    Summary of Interventions Across Lifespan

    • Children: Focus on growth, blood pressure, and family support. Peritoneal dialysis or transplant should be considered when needed.
    • Pregnant Women: Manage blood pressure closely, adjust dialysis frequency, monitor for preeclampsia, and optimize anemia treatment.
    • Older Adults: Address polypharmacy, ensure adequate hydration, consider conservative treatment options, and discuss advanced care planning.

    CKD Basics

    • Chronic Kidney Disease (CKD) is a progressive condition that worsens over time without proper management.
    • CKD impacts kidney function and can lead to kidney failure if left untreated.
    • Regular monitoring of kidney function through lab tests and follow-up visits is crucial for management.

    Dietary Management

    • Limit protein intake to reduce waste buildup in the body.
    • Choose high-quality proteins like lean meats and eggs in moderation.
    • Reduce sodium intake to control blood pressure and prevent fluid retention.
    • Fluid restriction may be necessary, use ice chips and sugar-free candies for managing thirst.
    • Avoid high-potassium foods like bananas, oranges, and potatoes.
    • Avoid high-phosphorus foods like dairy, nuts, and cola.
    • Older adults may need additional reminders or strategies to stay hydrated.

    Medication Management

    • Medications prescribed for CKD can include antihypertensives, phosphate binders, erythropoiesis-stimulating agents (ESAs), and others.
    • Avoid over-the-counter NSAIDs (ibuprofen) and specific antibiotics without consulting a healthcare provider.
    • Adhere to prescribed medications, and attend regular lab tests to monitor effectiveness and side effects.
    • Common side effects include nausea with phosphate binders and constipation with diuretics.

    Blood Pressure and Weight Monitoring

    • Monitor blood pressure daily and record weight.
    • Weight gain may indicate fluid retention and should be reported to a healthcare provider.
    • Target blood pressure should be maintained below 130/80 mmHg to slow CKD progression.

    Infection Prevention

    • Maintain frequent hand washing, especially for dialysis patients.
    • Hemodialysis patients should properly care for fistula or shunt sites.
    • Peritoneal dialysis patients should learn how to care for their catheter.
    • Encourage vaccinations including flu, pneumococcal, and hepatitis B.

    Symptom Management

    • Address anemia and fatigue with iron-rich food or supplements and a balance of rest and physical activity.
    • Gentle skin moisturizers, avoiding hot showers are recommended to manage uremic pruritus (itching).
    • Manage nausea by eating smaller meals, using prescribed antiemetics, and avoiding triggering foods.

    Lifestyle Changes

    • Quit smoking to prevent further blood vessel damage and accelerated CKD progression.
    • Limit or avoid alcohol consumption to prevent blood pressure increases and stress on the kidneys.
    • Engage in low-impact exercises like walking or swimming to manage weight, improve cardiovascular health, and reduce stress.

    Planning for Dialysis or Transplant

    • Dialysis education provides information on types (hemodialysis, peritoneal dialysis), schedule, and treatment expectations.
    • Kidney transplantation can be beneficial for eligible individuals and requires lifelong immunosuppressive therapy.

    Psychosocial and Emotional Support

    • Encourage patients to share their journey with family, friends, and support groups for emotional support.
    • Refer to mental health resources for depression, anxiety, or stress related to CKD.

    Special Considerations by Life Stage

    • Children and adolescents require growth monitoring, school accommodations for medical needs, and involvement in age-appropriate activities.
    • Pregnant women need close monitoring for preeclampsia, potential dialysis frequency adjustments, and dietary changes to support pregnancy.
    • Older adults face challenges with polypharmacy, limited mobility, and hydration. Strategies to prevent dehydration, falls, and constipation are important.

    Emergency Awareness

    • Recognize signs of complications, including chest pain (possible hyperkalemia), confusion (fluid/electrolyte imbalance), respiratory distress, or signs of infection, and seek immediate medical attention.
    • Report significant weight gain, persistent vomiting, uncontrolled blood pressure, or any changes in urination to healthcare providers.
