We report an unusual case of nephrotic syndrome due to membranous glomerulonephritis that responded to high-dose trimethoprim-sulfamethoxazole (TMP-SMX) treatment. A 52-year-old man presented with nephrotic syndrome and was diagnosed to have idiopathic membranous glomerulonephritis. At the time of diagnosis, his serum creatinine level was 1.2 mg/dl and daily urine protein excretion was 7.45 g. The patient was initially treated with angiotensin-converting enzyme inhibitor and diuretics. After a 6-month period, the patient remained symptomatic. Therefore, immunosuppressive therapy with a 6-month course of alternating corticosteroids with cyclophosphamide was commenced. Unfortunately, as a sequel of the immunocompromised state, the patient acquired severe pneumonia due to Pneumocystis jiroveci infection when he was on the fourth month of immunosuppressive therapy. At this time, he still had nephrotic range proteinuria and hypoalbuminemia. Because of the risk of aggravating infection, immunosuppressive agents were discontinued. A 14-day course of intravenous high-dose TMP-SMX therapy was given for the treatment of Pneumocystis jiroveci pneumonia. With this medication, not only the pneumonia was cured, but also a sustained remission of the nephrotic syndrome occurred. This case suggests a possible therapeutic role of high-dose TMP-SMX in membranous glomerulonephritis. We will discuss the possible mechanism.
