Title: Long-term effects of tacrolimus for maintenance therapy of lupus nephritis: a 5-year retrospective study at a single center. Author: Karasawa K, Uchida K, Kodama M, Moriyama T, Nitta K. Journal: Rheumatol Int; 2018 Dec; 38(12):2271-2277. PubMed ID: 30203113. Abstract: Previously, we reported the short-term effects of tacrolimus in treating lupus nephritis (LN); however, long-term data are lacking. We conducted a retrospective study of 26 adult patients with LN. Tacrolimus was initiated at a dose of 3 mg/day after induction therapy. We retrospectively collected data on renal response; modified lupus nephritis disease activity index (m-LNDAI), including hematuria, proteinuria, complement 3, anti-double-stranded DNA antibody, and estimated glomerular filtration rate (eGFR); and prednisolone (PSL) dose. Three patients discontinued tacrolimus treatment because of related complications, including acute myeloblastic leukemia, tremor, or a general personal choice or a desire to become pregnant. We analyzed data from 23 patients who were treated with tacrolimus over a 5-year period. The mean urinary protein/creatinine ratio decreased from a baseline of 0.24 (min 0.00-max 4.20) to 0.00 (0.00-7.05) at 5 years (p = 0.0134), while eGFR levels remained unchanged throughout the 5 years. The mean m-LNDAI decreased from a baseline of 3.00 (0.00-12.0) to 2.00 (0.00-4.00) at 5 years (p = 0.0074). The mean PSL dose decreased from a baseline of 0.33 (0.00-0.75) mg/kg/day to 0.15 (0.15-0.33) at 5 years (p = 0.001). Our results suggest that tacrolimus is potentially effective for treating LN and that the current dosage was generally well tolerated for long-term maintenance treatment in our patients with LN.[Abstract] [Full Text] [Related] [New Search]
