ABSTRACT
BACKGROUND: Glucose metabolism abnormalities frequently coexist with liver cirrhosis; however, the impact of these on liver-related outcomes has not been fully investigated. AIMS: We examined the influence of glucose abnormalities on overall mortality and liver-related complications in cirrhotic patients. METHODS: A prospective cohort of 250 subjects with compensated hepatitis C virus-related cirrhosis and without known diabetes underwent an oral glucose tolerance test and were subsequently followed for a median 201 weeks. RESULTS: At baseline, 67 (27%) had type 2 diabetes. During follow-up, 28 deaths and 55 first events of decompensation occurred. After adjustment for potential confounding covariates, overall mortality/liver transplant (sHR: 2.2, 95% CI: 1.04-4.6, P=0.04) and hepatic decompensation events (sHR: 1.9, 95% CI: 1.05-3.3, P=0.03) were significantly higher in diabetic patients. Subjects with a HOMA-IR >5 showed higher rates of mortality (sHR: 2.2, 95% CI: 1.03-4.8, P=0.04). The rates of hepatic decompensation were higher in patients with HOMA-IR >3 (sHR: 1.7, 95% CI: 1.04-2.9, P=0.03). Overall, 2h-plasma glucose was the most robust predictor of overall mortality (sHR: 2.5, 95% CI: 1.03-6, P=0.04) and decompensation (sHR: 2.7, 95% CI: 1.4-5.5, P<0.01). CONCLUSIONS: In compensated HCV-related cirrhotic patients, diabetes and marked insulin resistance are independently associated with poorer overall survival and increased risk of hepatic decompensation.

BACKGROUND: Multiple sclerosis (MS) was first reported in Cuba in 1965. The most frequent appearance is observed in the first six months of the year. OBJECTIVE: To determine the seasonal distribution and evolving forms of MS patients diagnosed with the disease between April 2004 and November 2007. METHOD: Twenty-one patients with suspected MS and 42 outbreaks were studied. Patients were classified according to Lublin and Revingold's criteria for clinical forms and according to McDonald. RESULTS: Most patients were classified in outbreak and remission and only two patients classified as primary-progressive multiple sclerosis. The higher number of outbreaks occurred in the first two quarters of the year. CONCLUSION: It is recommended to study further weather variables that may be related to the emergence of these outbreaks in our environment.

INTRODUCCIÓN: La esclerosis múltiple (EM) fue reportada en Cuba por primera vez en 1965. Se ha venido observando la aparición más frecuente en los primeros seis meses del año. OBJETIVO: Determinar la distribución estacional y formas evolutivas de EM en pacientes con diagnóstico de esta enfermedad entre abril 2004 y noviembre 2007. MÉTODO: Se estudiaron 21 pacientes con sospecha de EM y un total de 42 brotes. Los pacientes fueron clasificados según los criterios de Lublin y Revingold para las formas evolutivas y según los criterios de McDonald. RESULTADOS: Solo dos pacientes clasificaron en la forma evolutiva progresiva primaria; los primeros dos trimestres del año fueron los de mayor número de brotes. CONCLUSIÓN: Se recomienda profundizar en las variables climatológicas que pudieran tener vínculo con la aparición de estos brotes en nuestro medio.
