[A case of lupus nephritis resistant to steroid pulse therapy markedly improved by bolus intravenous cyclophosphamide therapy].
Bolus intravenous cyclophosphamide therapy (IVCY) has recently been the subject of considerable attention because it is occasionally very effective in the treatment of severe lupus nephritis. However only a few reports on this form of therapy have been noted in Japan. Described here is a patient with lupus nephritis accompanied by multi-organ disorders resistant to various therapies including methylprednisolone pulse therapy which responded dramatically to IVCY. The patient, a 37-year-old woman with a history of systemic lupus erythematosus (SLE) starting in 1984, was admitted to our hospital with increasing generalized edema and malaise in January 1987. Evaluation revealed hypoalbuminemia, hypoxemia, ascites, hypocomplementemia and leukopenia. The patient was treated with high-dose oral prednisolone, however the lupus nephritis deteriorated and a high urinary protein level, massive ascites, and pericardial and pleural effusions were noted. Involvement of the central nervous system (CNS) was also observed. Subsequently, she was treated with intravenous methylprednisolone pulse therapy and low-dose oral cyclophosphamide. As her disease was refractory to these treatments IVCY was initiated in May 1987, at a dose 0.5-0.8 g/m2. A total of 3 doses were given, and treatment was discontinued in October 1987 because of marked clinical improvement. After the final IVCY treatment she was discharged, and her subsequent clinical course over a year with a maintenance dose of prednisolone has been uneventful. Thus, IVCY seemed to be useful in the treatment of severe lupus nephritis. More rigorous comparisons of IVCY with other therapies are necessary.
