N02.3

Clinical Causes: Autoimmune diseases such as lupus erythematosus Infections that affect the kidneys, including post-infectious glomerulonephritis Certain genetic conditions affecting kidney function Vasculitis, which involves inflammation of blood vessels Other immune system disorders that lead to kidney inflammation

Key Symptoms: Persistent or recurrent blood in the urine (hematuria) Foamy urine due to protein loss Swelling in the legs, ankles, or around the eyes High blood pressure Fatigue and general malaise Possible flank pain or discomfort

Diagnosis Path: Diagnosing this condition involves a combination of medical history, physical examinations, and specialized tests. Key diagnostic procedures include: - Urinalysis: detects blood and protein in the urine - Blood tests: assess kidney function and look for signs of immune activity - Imaging studies: such as ultrasound to visualize kidney structure - Kidney biopsy: a small sample of kidney tissue examined under a microscope to confirm mesangial proliferation and inflammation These assessments help determine the extent of kidney damage and the specific type of glomerulonephritis present.

Treatment Protocols: Management of this condition aims to control inflammation, reduce symptoms, and prevent further kidney damage. Typical approaches include: - Medications such as corticosteroids to reduce inflammation - Immunosuppressive drugs to modulate immune responses - Blood pressure management, often with ACE inhibitors or ARBs - Diuretics to manage swelling - Dietary modifications to reduce salt and protein intake - Regular monitoring of kidney function and urine analysis In some cases, more advanced interventions might be necessary, including dialysis or kidney transplantation if kidney failure develops. Early detection and continual care are essential for improving outcomes.
