Study Notes
Overview of Glomerulonephritis
- Glomerulonephritis (GN) refers to a group of renal diseases caused by immune-mediated damage to the kidney's glomeruli.
- Common manifestations include hematuria, proteinuria, and azotemia.
- Acute GN can arise from primary renal issues or secondary illnesses, with examples like post-streptococcal GN (PSGN).
Kidney Structure and Function
- Each human kidney contains approximately 1 million nephrons, the functional units consisting of a renal corpuscle and a renal tubule.
- The glomerulus initiates plasma filtration, surrounded by the Bowman capsule, with three layers: fenestrated endothelium, glomerular basement membrane (GBM), and visceral epithelial cells (podocytes).
Epidemiology and Etiology
- GN accounts for 10-15% of end-stage renal disease (ESRD) cases in the U.S., often progressing without timely treatment.
- IgA nephropathy is the most prevalent form globally, while PSGN is declining in developed countries but remains common in areas like the Caribbean and Africa.
Clinical Features
- Symptoms may include facial swelling, dark urine, high blood pressure, and non-specific signs like fatigue and malaise.
- Pediatric populations (ages 5-15) are primarily affected by post-streptococcal GN, with males being more frequently impacted than females (2:1 ratio).
Mechanisms of Disease
- Immune-mediated mechanisms involve both humoral and cell-mediated pathways, triggering inflammatory responses and potential kidney damage.
- Different forms of GN exhibit varying patterns of immune complex deposition and inflammatory responses.
Histopathology
- Histological examination can reveal patterns like diffuse and focal proliferative changes, glomerular sclerosis, and cellular proliferation.
- Common findings include increased glomerular cellularity and the presence of crescents in rapidly progressive GN.
Diagnosis and Evaluation
- Diagnostic assessments include complete blood count, renal function tests (BUN, creatinine), imaging, and urine analysis for protein levels and casts.
- Biopsy may be necessary to determine the underlying cause and severity of GN.
Management Strategies
- Management depends on the underlying cause and may involve supportive care, specific therapies like corticosteroids, and immunosuppression.
- Chronic kidney disease (CKD) may develop without intervention, leading to cardiovascular-related morbidity.
Prognosis
- PSGN generally has a good prognosis, especially in children with full recovery in 6-8 weeks.
- Other forms like IgA nephropathy vary in prognosis, with some progressing to ESRD; frequent monitoring is essential.
Interprofessional Collaboration
- Effective care coordination among healthcare professionals is crucial in managing GN for optimal patient outcomes.
- Strategies must focus on improving communication and monitoring treatment efficacy at all stages of care.
Recent Trends
- Rising incidences of staphylococcus-related glomerulonephritis, coupled with demographic factors like age, gender, and underlying health conditions, affect treatment approaches.
- Long-term follow-up for complications and potential progression to ESRD remains critical for all patients diagnosed with GN.### Nephrotic Spectrum Diseases Overview
- Minimal Change Disease (MCD) exhibits a favorable prognosis across all age groups given a positive corticosteroid response.
- Primary morbidity in MCD arises from medication side effects rather than the disease itself.
Membranous Nephropathy
- About one-third of patients with subnephrotic proteinuria from membranous nephropathy may achieve effective management through conservative treatment.
- Spontaneous remission is possible even in cases with heavy proteinuria.
- For nephrotic syndrome patients, remission can take up to six months with proper treatment.
HIV-Associated Nephropathy
- Adequate treatment can slow progression of HIV-associated nephropathy; however, many eventually reach End-Stage Renal Disease (ESRD) and may require kidney transplantation.
Amyloidosis
- AL amyloidosis typically progresses to ESRD within 2 to 3 years.
- AA amyloidosis can achieve remission with effective management of the underlying condition.
Glomerulonephritis
- Can cause either acute kidney injury (AKI) or a gradual advancement to chronic renal failure (CKD).
- AKI often presents initially in rapidly progressive cases characterized by crescent formation.
- Conditions like vasculitis and Goodpasture syndrome are also linked with AKI caused by glomerulonephritis.
- Most patients ultimately progress to chronic glomerulonephritis, often necessitating dialysis due to CKD and ESRD.
Dietary and Lifestyle Management
- Sodium restriction is essential during acute nephrotic syndrome to manage symptoms.
- Progressive disease requires strict dietary limits: 2 g of sodium, 2 g of potassium, and 40 to 60 g of protein daily to mitigate waste build-up and fluid overload.
- Smoking cessation is critical in mitigating renal disease progression.
- Proper management of diabetes and hypertension is vital through lifestyle changes and therapy.
- Counseling on controlling hyperlipidemia is important for these patients.
Preventive Health Measures
- Patients with nephrotic syndrome face higher infection risks, making vaccinations (seasonal flu and pneumococcal) important.
Multidisciplinary Approach
- Coordinated care is crucial due to progressive disease and common comorbid conditions.
- The nephrologist plays a key role in managing glomerulonephritis, but involvement from other specialists is necessary.
- Patients with proteinuria or hematuria require thorough evaluation, including potential renal biopsies.
- Collaboration among histopathologists, immunologists, radiologists, and surgeons is essential for accurate diagnosis.
- Nursing staff are vital in providing treatment and educating families.
Monitoring and Community Integration
- Regular assessments of renal function are necessary for patients with chronic conditions.
- Connecting with local community doctors aids in ongoing care management.
- Patients with significantly reduced renal function require structured dialysis schedules, emphasizing coordination with dialysis units.
- Pharmacists should review medications that may adversely impact renal function and adjust regimens as needed, particularly around dialysis.
Importance of Interprofessional Communication
- Collaborative monitoring of patient progress is essential, ensuring communication among healthcare team members for therapeutic interventions.
- Prompt referrals to specialists can greatly enhance patient outcomes, underscoring the need for effective interprofessional communication in all aspects of patient care.
