Brief Summary

prospective, parallel, open-label clinical trial was performed on forty-seven adult renal transplant recipients receiving immunosuppressive therapy with CsA doses adjusted to attain trough concentrations of 100-150 μg/L, mycophenolate mofetil (MMF) at 750 mg q12 hr and prednisolone at 5 mg daily randomized into two groups, which received esomeprazole or pantoprazole at the same dose (40 mg once daily). To compare the influence of pantoprazole and esomeprazole on serum cyclosporine (CsA) levels in stable renal transplant recipients.Cyclosporine (C0), renal function and complete blood count were measured at baseline and for 6 months. Main outcome measures Clinical signs of rejection and renal function decline, assessed by serum creatinine elevations, caused by CsA level variations in either of the study groups.

Detailed Description

Study design and settings: This study is a prospective, single-centre, randomized, parallel, open-label 1:1 consecutive clinical trial of renal transplant recipients, with a follow-up 6 months; the study included an esomeprazole group (n = 25 at study completion) and a pantoprazole group (n = 22 at study completion). The study was conducted in the renal transplantation unit of the Nasser Institute in Cairo, Egypt.

Eighty renal transplant recipients were screened for eligibility. The sample size was determined by a power calculation using G power software version 3.0.10; the selected sample size showed an actual power of 0.95, α = 0.5 and an effect size of 0.8 for C0 levels of CsA and an actual power of 0.95, α = 0.5 and an effect size of 0.44 for serum creatinine levels.The participants were randomly assigned to one of two groups by single randomization. Each group received PPI therapy with a 40 mg/day dose of either esomeprazole (Ezogast; Copad Pharma, Cairo, Egypt) in group I (n = 25 at study completion) or pantoprazole (Pantoprazole; Pharo Pharma, Alexandria, Egypt) in group II (n = 22 at study completion).

In addition, participants continued to receive the immunosuppressant combination of CsA (Sandimmune; Novartis, East Hanover, NJ, USA), MMF (Cellcept; Roche, Basel, Switzerland) and the corticosteroid prednisolone (Solupred; Sanofi Aventis, Tours, France).

Administration: CsA was administered in two divided doses adjusted to achieve a C0 of 100-150 µg/L according to the transplantation centre protocol for maintenance blood CsA levels. The morning was dose separated from PPIs by at least 15 minutes, with MMF administered at 750 mg q12 hr and prednisolone administered at 5 mg daily. Each group received 40 mg/day PPI therapy on an empty stomach, and all medications were taken orally.

Renal function tests Included Parameter Assay Kits Serum creatinine QuantiChrom creatinine assay kit Blood urea nitrogen QuantiChrom urea assay kit Serum uric acid QuantiChrom uric acid assay kit Complete blood count measurements included Parameter Assay Kits Haemoglobin White blood cells (WBCs) UniCel DxH 800 Coulter Cellular Analysis System Platelets

Whole-blood C0 values in morning samples were determined spectrophotometrically using the CEDIA Cyclosporine PLUS Assay and the Indiko Plus Benchtop Analyzer (Thermo Fisher Scientific, Waltham, MA, USA)
