Clinical TrialEffect of switching from cyclosporine to tacrolimus on exhaled nitric oxide and pulmonary function in patients with chronic rejection after lung transplantation.
Previous studies have demonstrated that shifting immunosuppressive therapy from cyclosporine (CyA) to tacrolimus (FK) may arrest the decline in forced expiratory volume in 1 second (FEV(1)) during chronic rejection after lung transplantation. Exhaled nitric oxide (eNO) has been shown to be elevated during chronic rejection. We report the concomitant stabilization of FEV(1) and decrease in eNO after changing from CyA to FK therapy in patients with chronic rejection after lung transplantation. ⋯ This study illustrates that a switch from CyA to FK can stabilize pulmonary function in lung transplant patients with chronic rejection. This stabilization of FEV(1) is accompanied by a decrease in eNO, indicating that this treatment shift can reduce inflammation of airways during the course of chronic rejection. Consequently, measuring eNO may be extremely valuable in guiding the treatment of chronic rejection after lung transplantation.
