title: [A case of fulminant acute poststreptococcal glomerulonephritis showing mesangiolysis and crescent formation preceded by erysipelas].
abstract: A 66-year-old man with erysipelas was admitted with complaints of oliguria and massive proteinuria/hematuria. He was diagnosed as having acute poststreptococcal glomerulonephritis(APSGN) due to erysipelas infected by group A streptococcus pyogenes. On admission, his white cell count increased to 31,000, and CRP was 27.3 mg/dl. Serum urea nitrogen and creatinine were increased to 90.1 mg/dl and 4.5 mg/dl, respectively. He had diabetes mellitus(HbA1c 7.9%) and liver dysfunction(total bilirubin 3.5 mg/dl, AST 76 IU, ALT 41 IU) caused by alcoholic liver cirrhosis. Hypocomplementemia was found in addition to ASO 216 U/ml and ASK 10,240 x. After antibiotics treatment was initiated, inflammation of the erysipelas began to improve. Disseminated intravascular coagulation syndrome, probably due to sepsis, occurred on the 5th hospital day. He died of gastrointestinal bleeding on the 18th hospital day. Renal autopsy revealed 37% formation of fibrocellular crescents, and marked mesangiolysis was noted by light microscopy. Granular deposition of C3 and IgG was seen along the capillary walls on immunofluorescence study. Intramembranous deposits were scattered on electron microscopy. This case illustrates a fulminant type of APSGN, which was in part attributed to the presence of diabetes and alcoholic liver cirrhosis. Histological findings of crescent formation and marked mesangiolysis may account for the fulminant clinical course.
