Renal disease and sarcoidosis.

Renal involvement in sarcoidosis has recently been emphasized with increasing reports of associated glomerulonephritis. We report in detail a further case of mesangiocapillary glomerulonephritis in association with sarcoidosis. In addition, a review of 75 cases of sarcoidosis at Royal Melbourne Hospital over a 10-year period revealed one case of membranous glomerulonephritis and one case of granulomatous interstitial nephritis. Seven patients in the series had nephrocalcinosis, and eight further patients had abnormalities of urinary sediment of clinical symptoms of renal involvement. These findings suggest that, though renal failure is rare, renal involvement in sarcoidosis is more frequent than has previously been reported.
