[A case of systemic lupus erythematosus complicated by Nocardia farcinica].
We report a patient with systemic lupus erythematosus (SLE) complicated with nocardiosis. This case is very important that the complication of nocardiosis in SLE is very rare and the treatment to both SLE and nocardiosis is very difficult. A twenty-one-year old female was admitted to our hospital because of thoracic empyema and active lupus nephritis. Her medical history revealed that the diagnose of SLE was made when she was 18 with lymphocytopenia, proteinuria, positive antinuclear antibodies, and high titer of antibodies to native DNA. She was treated with prednisolne 60 mg daily and became better. Proteinuria appeared again in September 1995 and she was admitted to the former hospital. Renal biopsy proved diffuse proliferative glomeluronephritis (WHO IVb). She was treated with 1 g per day of methylprednisolone for 3 days and succeeded with 60 mg day of prednisolone. In early November she developed left chest pain and fever and chest X-ray demonstrated left pleural effusion. Antibiotics, antituberculosis, and antifungal therapy failed to subside her pleuritis and it turned to empyema. Then she was transferred to our hospital for further treatment. Nocardia farcinica was detected from the aspirated pleural fluid obtained at the former hospital. Drainage and intrathoracic impenem injection were effective. While long usage of minocycline was continued for the nocardiosis, 500 mg of cyclophosphamide pulse therapy to lupus nephritis was administrated. Two weeks later a new pulmonary lesion with left chest pain and liver abscess developed. Administration of trimethoprim-sulfamethoxazole subsided the nocardiosis. She was discharged with 1 g per day of proteinuria the prescribed 13 mg per day of prednisolone and continuous TMP-SMZ intake for nocardial infection. When immunosuppressive therapy must be given to the immunocompromised host, a more potent therapy must be added to avoid infection.
