Fanconi syndrome in an elderly patient with membranous nephropathy during treatment with the immunosuppressant mizoribine.

CEN Case Rep 2022 Jun 24. Epub 2022 Jun 24.

Department of Nephrology, Faculty of Medical Sciences, University of Fukui, 23-3 Shimoaizuki, Matsuoka, Eiheiji-cho, Yoshida-gun, Fukui, 910-1193, Japan.

We report on an 80-year-old man diagnosed with Fanconi syndrome induced by mizoribine after 4 weeks of administration to treat membranous nephropathy. Mizoribine is an oral immunosuppressant that inhibits inosine monophosphate dehydrogenase and is widely used in Japan for the treatment of autoimmune diseases and nephrotic syndrome, as well as after renal transplantation. Acquired Fanconi syndrome is often caused by drugs (antibacterial, antiviral, anticancer, and anticonvulsant drugs) and is sometimes caused by autoimmune diseases, monoclonal light chain-associated diseases, or heavy metal poisoning.

The role of ABCB1 gene polymorphisms in steroid-resistant nephrotic syndrome: Evidence from a meta-analysis of steroid-receiving patients.

J Gene Med 2022 Jun 13:e3436. Epub 2022 Jun 13.

Department of Pharmacy, Faculty of Science, Noakhali Science and Technology University, Noakhali, Bangladesh.

Previous studies in nephrotic syndrome have shown that three common variants in the ABCB1 gene, including rs1128503, rs2032582, and rs1045642, change the expression and activity of ABCB1, which may be responsible for the drug resistance. However, as a result of the inconclusive outcomes of these studies, we performed a meta-analysis to validate the association between ABCB1 polymorphisms and the susceptibility of steroid-resistant nephrotic syndrome (SRNS). The association was evaluated by calculating the odds ratio (OR) and 95% confidence interval. Read More
