Abstract
We report the case of a 34-year-old Japanese male with lipoprotein glomerulopathy (LPG). Renal biopsy showed LPG, and followed by a genetic analysis revealed a mutation in apolipoprotein E gene (APOE Kyoto; Arg25Cys). We started treatment with probucol, bezafibrate, losartan, and allopurinol. Urinary protein decreased in response to treatment but has remained at about 1.27 ± 0.71 g/gCr, and a repeat biopsy which was performed 1 year after the first biopsy showed no clear evidence of pathological remission and complication of other glomerular disease. After 5 years of follow-up after the start of treatment, renal function has almost maintained without apparent deterioration. Interestingly, the course of the urinary protein level closely paralleled his triglyceride and cholesterol levels in a long-term. This observation suggests the importance of tight control of lipid profiles as a means of renoprotection in LPG patient.
