title: Timely diagnosis and treatment essential in glomerulonephritis.
abstract: Glomerulonephritis is an important cause of kidney disease and, in the UK, the most common diagnosis in patients receiving chronic dialysis or waiting for kidney transplantation. A key feature is the presence of urinary abnormalities (proteinuria ± haematuria). Patients with nephrotic syndrome typically present with peripheral oedema, massive urinary protein loss and associated low serum albumin levels. Blood pressure and renal function, as measured by eGFR, are usually normal initially. Patients presenting with nephritic syndrome tend to be hypertensive with dipstick-positive or visible haematuria. There may be rapidly progressive renal dysfunction and fall in eGFR. Many patients will have a background genetic susceptibility to glomerulonephritis which may be triggered by environmental, infective or autoimmune factors. Autoimmunity, in combination with genetic factors, is responsible for a significant proportion of cases of glomerulonephritis. Infective agents such as viruses can precipitate minimal change disease. NSAIDs, lithium, penicillamine and heroin can cause nephrotic syndrome. Timely diagnosis and treatment of glomerulonephritis can help to minimise both the occurrence and severity of complications. All patients with glomerulonephritis should be managed according to CKD guidelines with CKD stage-appropriate measurement of renal function, blood pressure, and proteinuria.
