Acute glomerulonephritis during the third trimester of pregnancy.

We report a very rare case of acute poststreptococcal glomerulonephritis (PSGN) occurring in the eighth gestational month. The pregnancy succeeded despite initially severe nephrotic syndrome, and after delivery there was a complete recovery to normal renal function. Fetal prognosis was also good. The diagnosis of PSGN was made based on serological examinations and postpartum renal biopsy. Light and electron microscopic findings showed that the glomerular lesions were different from those of typical pre-eclampsia.
