ABSTRACT

BACKGROUND: Apolipoprotein AI/apolipoprotein E (apo-AI/apo-E) ratio change and its induction in non-hepatic tissues have been reported during liver development, regeneration, and several pathophysiologic states. The clinical implication of such changes is unclear, but these could reflect recovery and/or severity of liver damage. METHODS AND RESULTS: Using RT-PCR we analysed the mRNA expression of apo-AI and apo-E in peripheral white blood cells (PWBC) of patients with different liver diseases who underwent orthotopic liver transplantation (OLT) and compared its expression with the lipid profile and liver function tests. We found that patients showed higher levels of apo-AI mRNA without detection of apo-E mRNA on PWBC at the preoperative day, compared with healthy volunteers (HV). We found an apo-AI/apo-E mRNA ratio of 2.7 during the anhepatic stage, followed by a decrease to 1.3, 0.95, and 0.55 at days 30, 60, and 90, respectively. At the last time point, the apo-AI/apo-E ratio was similar to HV. At day 3 post-OLT, the lowest levels of high-density lipoprotein (HDL)-cholesterol (17 mg/dl; P<0.05) and the highest levels of aspartate aminotransferase, total bilirubin and alkaline phosphatase (77.5 IU/l, 37.9 g/dl, 177.8 IU/l, respectively; P<0.05) were detected. CONCLUSION: These results indicate that changes of HDL-cholesterol and apo-AI/apo-E mRNA ratio could be a good indicator of liver damage and/or hepatic functional recovery post-OLT.

ABSTRACT

Antecedentes. El hiperparatiroidismo primario (HPT) es una enfermedad frecuente cuyo tratamiento quirúrgico es efectivo. En nuestro hospital han ocurrido cambios en la estrategia quirúrgica de HPT: desde 1991 todos los enfermos son atendidos en un servicio de cirugía endocrina. Objetivo. Evaluar los resultados del tratamiento quirúrgico en los primeros 50 pacientes vistos en dicho servicio. Métodos. Se recabaron prospectivamante las características clínicas, estudios de laboratorio, hallazgos transoperatorios, complicaciones y evolución postoperatoria de 50 pacientes con HPT intervenidos de julio de 1991 a marzo de 1994. Resultados. La edad promedio de los enfermos fue de 53 años, 10 fueron del sexo masculino y 40 del femenino. Se indentificó un adenoma como responsable de la enfermedad en 43 pacientes, cinco cursaron con hiperplasia, en uno se demostró un adenoma doble y en uno más un adenoma en una glándula supernumeraria. Se logró curación de la enfermedad en el 96 por ciento de los enfermos después de un procedimiento quirúrgico y en el 100 por ciento después de reexploración quirúrgica durante la misma hospitalización. Conclusión. Nuestros resultados apoyan el empleo del tratamiento quirúrgico en HPT
