Everolimus Rescue Treatment for Chronic Rejection After Pediatric Living Donor Liver Transplantation: 2 Case Reports.

Chronic rejection (CR) remains a challenging complication after liver transplantation. Everolimus, which is a mammalian target of rapamycin inhibitor, has an anti-fibrosis effect. We report here the effect of everolimus on CR. Case 1 was a 7-year-old girl who underwent living donor liver transplantation (LDLT) shortly after developing fulminant hepatitis at 10 months of age. Liver function tests (LFTs) did not improve after transplantation despite treatment with tacrolimus + mycophenolate mofetil (MMF). Antithymoglobulin (ATG) and steroid pulse therapy were also ineffective. The patient was diagnosed with CR, and everolimus was started with a target trough level of about 5 ng/mL. LFTs improved and pathological examination showed no progression of hepatic fibrosis. Case 2 was a 10-year-old girl with Alagille syndrome who underwent LDLT at 1 year of age. She had biopsy-proven acute cellular rejection with prolonged LFT abnormalities beginning 3 years after transplantation. She was treated with steroid pulse therapy, followed by MMF, tacrolimus, and prednisolone. Her condition did not improve, even after subsequent ATG administration. CR was suspected based on liver biopsy in the fourth postoperative year, and everolimus was introduced. The target trough level was around 5 ng/mL, but was reduced to 3 ng/mL due to stomatitis. Four years have passed since the initiation of everolimus, and LFTs are stable with no progression of liver biopsy fibrosis. We describe 2 cases in which everolimus was administered for CR. In both cases, LFTs improved and fibrosis did not progress, suggesting that everolimus is an effective treatment for CR after LDLT.

Pulmonary Arterial Pressure Management Based on Oral Medicine for Pediatric Living Donor Liver Transplant With Portopulmonary Hypertension.

Pediatric living donor liver transplantation (LDLT) in patients with advanced portopulmonary hypertension (PoPH) is associated with poor prognoses. Recently, novel oral medications, including endothelin receptor antagonists (ERAs), phosphodiesterase 5 (PDE5) inhibitors, and oral prostacyclin (PGI2) have been used to treat PoPH. Pediatric patients with PoPH who underwent LDLT from 2006 to 2016 were enrolled. Oral pulmonary hypertension (PH) medication was administered to control pulmonary arterial pressure (PAP). Four patients had PoPH. Their ages ranged from 6 to 16 years, and their original diseases were biliary atresia (n = 2), portal vein obstruction (n = 1), and intrahepatic portal systemic shunt (n = 1). For preoperative management, 2 patients received continuous intravenous PGI2 and 2 oral medications (an ERA alone or an ERA and a PDE5 inhibitor), and 2 received only oral drugs (an ERA and a PDE5 inhibitor). One patient managed only with intravenous PGI2 died. In the remaining 3 cases, intravenous PGI2 or NO was discontinued before the end of the first postoperative week. Postoperative medications were oral PGI2 alone (n = 1), an ERA alone (n = 1), or the combination of an ERA and a PDE5 inhibitor (n = 1). An ERA was the first-line therapy, and a PDE5 inhibitor was added if there was no effect. New oral PH medications were effective and safe for use in pediatric patients following LDLT. In particular, these new oral drugs prevent the need for central catheter access to infuse PGI2.

Health care systems in transition: Turkey

The Health Systems in Transition (HiT) series provide detailed descriptions of health systems in the countries of the WHO European Region as well as some additional OECD countries. An individual health system review (HiT) examines the specific approach to the organization, financing and delivery of health services in a particular country and the role of the main actors in the health system. It describes the institutional framework, process, content, and implementation of health and health care policies. HiTs also look at reforms in progress or under development and make an assessment of the health system based on stated objectives and outcomes with respect to various dimensions (health status, equity, quality, efficiency, accountability).
