GPs should be vigilant for glomerulonephritis

Area of Science:

• Nephrology
• Histopathology
• Renal Medicine

Background:

• Glomerulonephritis is defined as inflammation of the glomeruli, a histological diagnosis from renal biopsy.
• It is the second leading cause of end-stage renal disease (ESRD) in the UK.
• Disease presentation varies widely, from asymptomatic chronic disease to acute, rapidly progressive forms.

Purpose of the Study:

• To outline the diagnostic and management principles for glomerulonephritis.
• To emphasize the importance of early detection for acute glomerulonephritis.
• To discuss the management goals for chronic glomerulonephritis and chronic kidney disease (CKD).

Main Methods:

• Diagnosis relies on renal biopsy for histological confirmation.
• Clinical assessment involves recognizing compatible patterns, comparing current and historical lab results (urinalysis, serum creatinine/eGFR).
• Additional testing is used to confirm, quantify, and identify specific patterns of glomerulonephritis.

Main Results:

• Many acute glomerulonephritis cases respond well to early treatment, preventing irreversible renal function loss.
• Chronic glomerulonephritis often presents as CKD and is associated with hematuria, proteinuria, and hypertension.
• Renal ultrasound may reveal small kidneys in advanced disease.

Conclusions:

• Prompt identification and treatment of acute glomerulonephritis are vital to preserve kidney function.
• Management of both glomerulonephritis and CKD aims to slow progression, prevent complications, and prepare for renal replacement therapy.
• Chronic glomerulonephritis requires ongoing management, with a 10-year survival rate of 63%.
