RESUMO
The association between chronic liver disease and plasmatic lipids and glucidic metabolism was studied. The liver was evaluated with biochemical variables, ultrasound and upper gastrointestinal endoscopy. 12 chronic liver diseases patients and 10 normal were studied. 83.3% of patients showed lipidic abnormalities, 66.6% on the cholesterol levels and 41.7%, reduced HDL. When patients received 100 gr of glucose the response was abnormal in 83.3%. These results were compared with other "liver function test". 75% had abnormal bilirubin, 58.3% abnormal albumin, prothrombin time 58.3%, aminotransferases 75%. Esophageal verices were found in 75% of cases and ultrasound abnormalities in 91.6% (27.3% cirrhosis, 54.4% diffuse abnormal patter and 18.2% splenomegaly). These findings show that lipidic and glucidic metabolism, and ultrasound, in chronic liver diseases are the more frequent abnormalities.

Two different areas of metropolitan zone in Venezuela were studied in relationship to the immunological condition associated with A, B, C and D viral hepatitis in 557 healthy subjects. We performed clinical history with personal information, that was subsequently correlated with results of the hepatitis markers. General results show prevalence different from previous reports: Anti-HAV: 90.84%, HBsAg: 1.62%, Anti-HBc: 10.6%, Anti-HCV: 0.36% y Anti HDV: 0%.

Preliminary results of a prospective, comparative and randomized study on 119 sero-negative volunteers with increased risk to acquire hepatitis B, aimed to evaluate the comparative efficacy of a recombinant vaccine administered either intramuscularly or intradermally, are discussed. A short vaccination schedule of three consecutive doses given on months 0, 1 and 2 was used. Distribution by sex and age for both groups was similar. Seroconversion and seroprotection rates were comparable (96% and 96% Vs. 98% and 93%, respectively). The geometric mean titre of anti-HBsAg in individuals immunized via I.M. (155 IU/L) was significantly higher to that of the I.D. group (71 IU/L). On the other hand, the rate of good response (> 100 IU/L) was also higher in the I.M. group (67% Vs. 39%). The percentage of good responder in women was consistently higher than in men for both groups (75% Vs. 13%, respectively). In 68 vaccinees, samples were obtained one year later. The levels of anti-HBsAg and the anamnesic response after a booster of the vaccine are currently being assayed.
