AIMS: Hypercholesterolemia is one of the factors which deteriorate renal function in NS especially due to FGS. LDL-A is a potential option for treating NS due to FGS accompanied by hypercholesterolemia and resistant to conventional drug therapy with steroids and/or cyclosporine A (CsA). As reported by Muso et al. [2001], LDL-A combined with drug therapy yields more rapid relief from NS and better prognosis than drug therapy alone. However, very limited data are available on outcome at several years after treatment. The aim of this study was to clarify long-term outcome of NS patients treated with LDL-A and to evaluate the effectiveness of this treatment. PATIENTS AND METHODS: To clarify the long-term outcome of LDL-A, we conducted a retrospective survey on outcome up to 5 years. From 36 hospitals in Japan, 41 patients with NS whose short-term outcomes with LDL-A were reported from 1999-2004 were collected and analyzed. RESULTS: In all, 29 and 15 patients with outcomes determined at 2 and 5 years after treatment, respectively, were obtained. At 2 and 5 years after treatment, 62 and 87% of patients, respectively, were classified into complete or Type 1 incomplete remission. The strength of correlations between outcome and several factors including parameters of renal function measured before and after treatment and treatment condition revealed that early administration of LDL-A after the onset of NS provided a good long-term outcome. The data also suggest that more drastic decrease of LDL favored a better prognosis. CONCLUSIONS: In NS due to FGS treated with LDL-A, long-term outcome was as good as short-term outcome. Early administration of LDL-A after the onset of NS provided a good long-term outcome. To obtain more precise findings regarding the effects of this treatment, a large-scale prospective study will be needed.
