Long-term Glomerular Filtration Rate and Kidney Disease: Improving Global Outcomes Stage Stability After Conversion to Once-Daily Tacrolimus in Kidney Transplant Recipients
Close monitoring of estimated glomerular filtration rate (eGFR) is important for early recognition of worsening renal function to prevent further deterioration. Safe conversion from twice-daily tacrolimus (TD-Tac) to once-daily tacrolimus (OD-Tac) has been reported, but the effects on eGFR are contrasting. The aim of our study is to evaluate long-term stability of eGFR after 1:1 conversion from TD-Tac to OD-Tac and the effects on serum cytokine blood levels. Forty-six consecutive kidney transplant recipients treated with TD-Tac 3 to 5 years post-transplant, with stable renal function, were enrolled in the study (2009–2011). Clinical and biochemical parameters were evaluated for 12 months before conversion up to 6 years after conversion. The patients served as their own controls. A panel of cytokines was evaluated repeatedly during the first year after conversion. Mean values of eGFR were not different long-term after conversion (P = .11) compared with baseline, and the majority of patients remained stable on Kidney Disease: Improving Global Outcomes stage during the study period; eGFR was stable in 30.0% after 5 years, decreased > 1 mL/min/1.73 m2/y in 13.3%, and improved > 1 mL/min/1.73 m2/y in 56.7%. Cytokine levels and C-reactive protein did not show any significant deterioration. Metabolic parameters were stable during the 6 years of follow-up. OD-Tac therapy can preserve an effective immunosuppressive state together with a safe profile of eGFR.
