Treatment of glomerulonephritis in the elderly.

With the increasing use of renal biopsy in the elderly, glomerulonephritis is now known to be a common finding. Whereas membranous glomerulonephritis and minimal change disease are common in younger and older adults, primary amyloidosis and crescentic glomerulonephritis are more common in the elderly. Other glomerulonephritides such as focal segmental glomerulosclerosis or IgA nephropathy are very uncommon in the elderly. Because of the serious consequences of the nephrotic syndrome and acute and chronic renal failure in the elderly, aggressive treatment with immunosuppression should not be withheld. Caution should always be taken because of the presumed greater morbidity and mortality from such treatment in the elderly.
