Clinical effects of sirolimus treatment in patients with increased serum creatinine levels after renal transplant

Purpose: To observe the clinical effects of sirolimus (SRL) immunosuppressive therapy in patients with progressively increasing levels of serum creatinine (Scr) after renal transplant. Methods: In total, 180 patients whose Scr levels had been rising after renal transplant were given an oral calcineurin inhibitor (CNI): either cyclosporine A (CsA) or tacrolimus (FK506). All patients were treated at People’s Hospital of Zhengzhou, China, between January 2011 and December 2013, and were given SRL-based conversion treatment. Scr level and glomerular filtration rate (GFR) were observed before and 1, 3, and 6 months after treatment initiation. In addition, liver function, blood glucose, blood lipid levels, rejection reaction incidence, and mortality were recorded to evaluate the effects of SRL. Results: Scr levels were 116.60 ± 30.60 μmol/L and 119.00 ± 24.60 μmol/L, and GFR was 70.00 ± 19.70 mL/min and 75.90 ± 15.60 mL/min, at 3 and 6 months after treatment, respectively. The 3- and 6- month Scr and GFR values were statistically different (p < 0.05) compared to pre-treatment levels (Scr: 144.10 ± 61.70 μmol/L vs and GFR: 59.10 ± 16.20 mL/min. Acute rejection (AR) occurred in 20 patients (13.30 %) within 6 months of treatment initiation, but rejection was reversed with conventional methylprednisolone therapy. Twenty-one patients (11.70 %) developed lung infections, but all were cured. There were no significant differences in liver function before and after treatment. Conclusion: SRL-based immunosuppressive therapy is effective in treating patients with increased Scr levels after renal transplant.

Determinación del comportamiento del riesgo cardiovascular en paciente postrasplante hepatico en Fundacion Cardioinfantil

El trasplante hepático es una opción terapéutica para enfermedad hepática avanzada cada vez más frecuente en Colombia. La sobrevida del 80% a 5 años conlleva a un aumento del riesgo cardiovascular y de eventos cardiovasculares, por esta razón esta investigación determina el comportamiento del riesgo cardiovascular en los pacientes con trasplante hepático de la Fundación Cardioinfantil, realizado en 3 años de seguimiento . Lo encontrado en esta investigación es que existe un aumento del riesgo cardiovascular a tres años en pacientes post trasplante hepático, estadísticamente significativo, principalmente secundario a hipertensión, diabetes e hipertrigliceridemia. El aumento es mayor a lo descrito en la población general, y similar a otros pacientes trasplantados, en un periodo de 5 años
