Abstract.
Six Japanese children with severe lupus nephritis received prompt initiation of methylprednisolone pulse therapy (MPT). After three courses of MPT, oral prednisolone combined with a 12-week course of oral cyclophosphamide was given and prednisolone was tapered. At presentation, urine protein excretion and histological indices of the mean activity index and the mean chronicity index in the patients were 2.2±1.5 g/day, 10.3±2.0, and 2.8±1.2, respectively. Urine protein excretion and the activity index decreased significantly at the second renal biopsies obtained at a mean interval of 8 months after the first [0.1±0.1 g/day and 3.5±1.4 (P<0.05), respectively], while the chronicity index did not change. At the latest observation (mean interval 53 months), all showed clinical and serological improvement. Complete remission was achieved in two patients, and no patient showed renal impairment. Although this case series is without controls, our treatment protocol may be of benefit to Japanese children with severe lupus nephritis.
