Study Notes
Renal Function and Importance
- Essential for maintaining body fluid volume and composition.
- Crucial for excretion of waste products and medications.
- Advances in management have improved outcomes for previously fatal renal diseases.
- Increasing number of patients receiving kidney transplants.
Causes of Loss of Renal Function
- Renal Diseases such as infections, glomerulonephritis, hypertension, and diabetes.
- Renal hypofunction resulting from severe shock or hemorrhage.
- Blockages in renal outflow caused by kidney stones or prostate tumors.
Chronic Kidney Disease (CKD)
- Characterized by progressive and irreversible kidney damage.
- Initially asymptomatic, with symptoms emerging as kidney function declines.
- Affects multiple body systems, leading to various complications.
Effects of Chronic Kidney Disease
- Metabolic Effects: Increased thirst, nocturia, glucose and electrolyte disturbances.
- Cardiovascular Effects: Hypertension and development of atheroma.
- Gastrointestinal Effects: Loss of appetite, weight loss, nausea, vomiting, peptic ulcers, and hiccups.
- Neuromuscular Effects: Headaches, drowsiness, and tremors.
- Haematological Effects: Increased bleeding risks due to platelet dysfunction and anaemia from erythropoietin deficiency.
- Other Effects: Bruises, skin rashes, and increased susceptibility to infections.
Symptoms of Kidney Disease
- Early signs often include changes in urination patterns and appetite.
- Progressing symptoms may manifest as gastrointestinal distress or neuromuscular issues.
General Management of Kidney Disease
- Regular monitoring and assessment to manage comorbidities.
- Treatment options vary based on the underlying cause and severity of kidney dysfunction.
Dental Relevance and Management
- Importance of considering renal function in oral health and treatment planning.
- Patients may present with specific oral manifestations related to their renal condition.
- Dental professionals should be aware of potential bleeding issues and prescribe medications carefully, considering renal function.
Oral Manifestations Related to Kidney Disease
- Potential for increased oral mucosal lesions or infections due to immunocompromised state.
- Attention required for management of periodontal disease in patients with renal issues.
Importance of Renal Function
- Maintains fluid balance in the body.
- Excretes waste products and medications, which is crucial for dosage considerations in clinical settings.
Causes of Loss of Renal Function
-
Renal Disease
- Urinary tract infections (UTIs) affecting bladder (cystitis), urethra (urethritis), or kidneys.
- Hypertension can lead to long-term kidney damage.
- Diabetes mellitus is a major risk factor for kidney complications.
- Glomerulonephritis results from an immune response damaging kidney filters.
- Congenital abnormalities such as renal hypodysplasia or agenesis lead to underdeveloped or missing kidneys.
-
Renal Hypofunction
- Severe bodily shock, e.g., sepsis, impairs kidney function.
- Significant hemorrhage can affect renal function.
-
Blocked Renal Outflow
- Kidney stones composed of calcium, ammonia, and uric acid can obstruct urine flow.
Effects of Kidney Disease (CKD)
-
Physical Symptoms
- Bruises due to urea accumulation in blood.
- Skin rashes and increased susceptibility to infections, especially with steroid use.
-
Metabolic Effects
- Glucosuria, excessive thirst, increased nighttime urination, fatigue, and electrolyte imbalances.
-
Cardiovascular Effects
- Hypertension, lipid build-up, and atherosclerosis contribute to increased blood pressure.
- Gingival hyperplasia as a side effect of blood pressure medications complicates dental care.
-
Gastrointestinal Effects
- Loss of appetite, food stagnation leading to dental plaque, and weight loss from dietary restrictions.
- Nausea, vomiting, acid reflux causing tooth erosion, and peptic ulcers.
- Hiccups due to reduced waste filtration.
-
Neuromuscular Effects
- Headaches, drowsiness, weakness, and tremors.
-
Hematological Effects
- Anemia from erythropoietin deficiency affecting oxygen transport.
- Increased bleeding risk due to platelet dysfunction or anticoagulant medications.
Symptoms of Kidney Disease
- Poor appetite and significant weight loss.
- Shortness of breath (dyspnea).
- Insomnia and increased urine production.
- Presence of blood in urine (hematuria).
- Swelling in extremities due to water retention.
General Management of Kidney Disease
- Dietary modifications include low protein intake, with limitations on meat, eggs, beans, and lentils.
- Restriction of potassium-rich foods such as potatoes, bananas, broccoli, and oranges.
Dental Relevance & Management
- Appointment lengths should be longer to accommodate patient needs.
- Awareness required around potential drug interactions, especially with local anesthetics (LA).
- Reduced doses of LA may be necessary due to impaired drug metabolism.
Clinical Dental Relevance
- Consider underlying renal disease affecting overall health.
- Increased risk for hepatitis B and other viral infections.
- Potential for bone lesions in the jaw observable in diagnostics.
- Importance of a balanced diet; low protein and potassium considerations for long-term health.
- Assess bleeding tendencies, especially in patients on anticoagulants due to dialysis or transplant.
- Monitor for hypertension effects, such as gingival hyperplasia, impacting oral hygiene and treatment.
- Patients on corticosteroids or immunosuppressive therapy may experience delayed healing and increased infection risk.
