Acute focal bacterial nephritis presented as acute renal failure and hepatic dysfunction in a renal transplant recipient.
We describe acute focal bacterial nephritis (AFBN) presented as acute renal failure and hepatic dysfunction in a renal transplant recipient. He had received a renal transplantation 5 years previously and maintained good renal function without an episode of acute rejection or any urinary abnormalities. He had been an HBsAg carrier and showed mild elevation of liver enzymes after renal transplantation. For 5 days before admission, the patient suffered from fever, graft kidney swelling, tenderness and oliguria. On admission, renal biopsy was performed and solumedrol pulse therapy was started under the impression of acute rejection. The following laboratory findings revealed acute renal failure and hepatic dysfunction. From the abdomen CT and renal biopsy findings this case was confirmed as AFBN in a grafted kidney. With successive hemodialysis and antibiotic therapy clinical symptoms and renal function improved promptly. In acute hepatic dysfunction we discontinued cyclosporine (CsA) to prevent irreversible fulminant hepatic failure until the normalization of liver function. It should be considered that AFBN must be included in the differential diagnosis of acute rejection, and the early diagnosis and treatment of AFBN is important to save the grafted kidney. In addition, early withdrawal of CsA is essential to prevent irreversible hepatic failure when infection triggers hepatic dysfunction in HBsAg-positive renal transplant recipients.
