Abstract

The prognosis of lupus nephritis (LN) was studied retrospectively in two LN categories, LN manifested initially at systemic lupus erythematosus (SLE) onset (I-LN) and LN of delayed manifestation after SLE onset (D-LN), based on a chart review (C) of 154 SLE (85 LN) patients with a mean observation of 20.8 +/- 9.3 years and a questionnaire study (Q) of 125 LN patients outside our hospital with mean observation of 17.6 +/- 9.2 years. In both study groups, half of I-LN patients were relapse-free by Kaplan-Meier analysis after initial therapy, and the relapsed I-LN patients responded to retherapy at higher 5-year relapse-free rates than those of patients receiving initial therapies for D-LN. At last observation, a higher frequency of prolonged remission was shown in I-LN compared with D-LN patients (C: 22/31, 71% versus 14/49, 29%, P < 0.01; Q: 65/89, 73% versus 11/33, 33% P < 0.01) and also a higher frequency of irreversible renal damage in D-LN compared with I-LN patients (C: 25/49, 51% versus 2/31, 6%, P < 0.001; Q: 14/33, 42% versus 6/89, 7%, P < 0.001), although class IV pathology was common in patients (C) in both LN categories. Onset time of lupus nephritis in the course of SLE may affect renal prognosis.
