| Berger's disease | <disease, nephrology> This is a form of glomerulonephritis that results from the deposition of circulating IgA antibody in the kidney tissues. Inflammation of the glomerulus (glomerulonephritis) is the result and may present as acute glomerulonephritis, chronic glomerulonephritis or rapidly progressive glomerulonephritis. Berger's disease is usually detected in an individual with one or two bouts of haematuria (usually begins during or soon after a respiratory infection) and no other symptoms of renal disease. Only rarely, will Berger's disease permanently affect kidney function and progress to chronic renal failure. This renal disorder more commonly affects males in the 16-40 age group. (11 Jan 1998) |
| Berger's focal glomerulonephritis | Glomerulonephritis affecting a small proportion of renal glomeruli which commonly presents with haematuria and may be associated with acute upper respiratory infection in young males, not usually due to streptococci; associated with IgA deposits in the glomerular mesangium and may also be associated with systemic disease, as in Henoch-Schonlein purpura.
