A controlled trial on nutrition supplementation in ambulatory patients with decompensated alcoholic liver disease was carried out during 1 year. Fifty-one patients were studied; 26 were assigned to an experimental group receiving a daily supplement of 1000 kcal and 34 g of proteins given as a casein-based enteral nutrition product and 25 to a control group receiving one placebo capsule. Patients were examined in a special clinic once a month or more if required. Sixty-eight percent of patients admitted to alcohol ingestion or had alcohol in urine samples on at least one occasion. Dietary recalls showed a significantly higher protein and caloric intake in case patients subjects (p < .0001). Nine patients died during the study, three case patients and six control patients (p = NS). The frequency of hospitalizations was significantly less in the experimental group. This difference was attributed to a reduction in severe infections. Mid-arm circumference, serum albumin concentration, and hand grip strength improved earlier in case patients, although both groups had a significant improvement in these parameters. Bilirubin and aspartate aminotransferase decreased and prothrombin time increased significantly in both groups during the study period, without differences between groups. It is concluded that nutrition support decreases nutrition-associated complications in patients with alcoholic liver disease.
This study analyzes whether increased body weight is related to histological liver damage in chronic alcoholic patients. Data from 152 recently abstinent alcoholics without evidences of liver failure were analyzed. Liver biopsies were scored for the presence of fat, necrosis, fibrosis, inflammation, and Mallory material. Total histological score correlated significantly with body weight (BW), length of alcoholism (L), and age (A) but not with the amount of ethanol ingested (E). Forward stepwise multiple regression analysis with histological score as the dependent variable gave significant F values for BW and L but not for A. Patients with severe damage had higher BW than patients with mild damage. The group with BW greater than 110% showed a higher histological score. These results confirm the association between increased BW and liver damage in asymptomatic alcoholic patients suggesting that overweight is a risk factor for alcoholic liver disease.
A clinical, serological, parasitological and therapeutic study of cutaneous leishmaniasis was carried out in a low sub-andean area (250-800 metres) of the La Paz Department, Bolivia. A team of seismic prospectors (350 workers) was surveyed for 12 months. Of 200 suspected cases of cutaneous leishmaniasis, 185 were serologically or parasitologically confirmed (incidence 52.8%). Those exposed to the greatest risk of infection were working in a virgin forest environment. Leishmanial organisms were isolated from 26 of the workers, either by in vitro cultivation or inoculation into hamsters. Isoenzyme characterization of the organisms by cellulose acetate electrophoresis showed them to be Leishmania braziliensis braziliensis [corrected]. The results of treatment of 168 patients with a pentavalent antimonial drug are also reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
