Predictive factors of clinical outcome in patients with diffuse proliferative lupus nephritis treated early by intravenous methylprednisolone pulse therapy.

摘要

Background. Diffuse proliferative lupus nephritis (DPLN) is associated with significant morbidity and mortality unless aggressive immunosuppressive therapy is initiated early in the course of the disease. It has been observed that with steroid pulse therapy, some patients with DPLN enter clinical remission while others do not. The factors predictive of clinical remission with steroid pulse therapy in these patients has not yet been elucidated. Methods. The authors retrospectively reviewed the records of 52 consecutive patients of DPLN treated by steroid pulse therapy in order to compare the characteristics of patients in the clinical remission group and those in the non-remission group. Clinical remission was defined as a serum creatinine level of
