Nephritis
Nephritis refers to inflammation of the kidneys, specifically affecting the glomeruli and/or interstitial tissue. This condition can impair renal function, leading to symptoms such as hematuria, proteinuria, edema, hypertension, and reduced glomerular filtration rate. Etiologies vary, including autoimmune disorders, infections, and certain medications. Untreated, nephritis can progress to chronic kidney disease and end-stage renal failure, necessitating careful diagnosis and management to preserve kidney function and prevent complications.
