RESUMEN
OBJECTIVE: To evaluate both the opinion that living liver donors have of the process and the psychological, economic, and social consequences of donation. MATERIAL AND METHODS: Six months after the donation, an anonymous survey was sent to 22 donors of the right liver lobe between March 2000 and December 2002. RESULTS: 15 surveys were returned with all of the questions answered. Almost all the donors had no prior knowledge of living donation. When they were considered to be suitable donors, all of them felt happy, 21% were scared and 15% felt joy and insecurity. The information provided was well understood and accurately described the experiences of 93% of donors. All donors understood the vital risk, and 93% understood that transplantation is not always completely successful. All donors would repeat the experience. Mean hospital stay was 12.6 days. Mean convalescence was 50.6 days. Salaried donors were on sick leave for a mean of 96.4 days (21-150 days), causing financial problems in six cases (36%), due to no financial compensation and compulsory redundancy in one case. All donors had completely recovered at six months after donation. DISCUSSION: Adult living donation of the right liver lobe is an accepted therapeutic alternative. In order to regulate medical and economic protection to avoid additional disturbances after donation, the public, patients, and physicians require more complete information about living donation.

BACKGROUND: Malnutrition seen in chronic alcoholics is partly due to reduced energy intake. Leptin is a peptide hormone implicated in the regulation of appetite and expenditure of energy. The prevalence and significance of abnormal circulating leptin levels in alcoholics, as well as the relationship of these levels with nutritional status, liver disease, and ethanol consumption, remain uncertain. METHODS: Serum leptin levels were measured in 60 active asymptomatic alcoholics, 20 active alcoholics with cirrhosis of the liver, 20 abstinent alcoholics, and 60 controls. Nutritional status and ethanol consumption also were assessed. RESULTS: In the control group, circulating leptin levels (mean 4.7+/-0.3 microg/liter) correlated with body fat stores. Despite showing a lower fat area of the arm, active alcoholics had significantly higher leptin levels than the controls (p < 0.001), regardless of the presence of cirrhosis. By contrast, none of the abstinent alcoholics showed hyperleptinemia. In the multivariate regression analysis, the fat area of the arm (p < 0.001), the lifetime ethanol consumption (p = 0.007), and the number of cigarettes smoked per day (p = 0.02) were found to be independent factors that influenced leptin levels in active alcoholics. After we adjusted for age, fat area of the arm, and tobacco consumption, a significant correlation was observed between lifetime consumption of ethanol and serum leptin concentrations (r = 0.36, p < 0.001). CONCLUSIONS: Circulating leptin levels are increased in a dose-dependent manner in chronic alcoholism, regardless of nutritional status or the presence of compensated liver disease.

BACKGROUND: Chronic excessive ethanol consumption exerts a deleterious effect on the myocardium. Although the effects of chronic alcoholism on systolic cardiac function are well known, diastolic involvement has been evaluated only partially. Therefore, we determined the presence of left ventricular diastolic impairment in chronic alcoholics and its relation with simultaneous systolic dysfunction. We also assessed the influence of ethanol consumption in diastolic impairment. METHODS: Thirty-five alcoholics with cardiomyopathy (ejection fraction < or = 50%) and 77 alcoholics with normal systolic function (ejection fraction > 50%) were evaluated. Assessment of New York Heart Association functional class, history of ethanol intake, technetium-99m radionuclide angiocardiography, and bidimensional Doppler echocardiography with evaluation of systolic and diastolic left ventricular function were performed. RESULTS: Diastolic function impairment was present in one third of the alcoholics without cardiomyopathy, compared with two thirds of the patients with cardiomyopathy (p < 0.01). A pseudonormalization phenomenon of diastolic function was observed in patients with more advanced systolic dysfunction (ejection fraction < 32%). The deterioration of the diastolic parameters correlated with ethanol consumption, regardless of age (r = 0.44, p < 0.001 for ratio of peak velocity of the transmitral flow in early diastole and peak velocity of atrial contraction flow, with lifetime dose of ethanol). CONCLUSIONS: There seems to be a dose-dependent effect of ethanol on systolic and diastolic heart function. Diastolic function impairment is present in one third of alcoholics with normal systolic function and is even more frequent when systolic dysfunction coexists.
