Seventy-six cases of acute viral hepatitis in the elderly (65 years old or older) were reviewed. Their clinical symptoms, biochemical pictures and clinical courses were compared with patients less than 40 years old (young) and those 40-64 years old (middle-aged). There were 51 men and 25 women with the mean age of 69 years (range 65 to 78 years). The most common etiology of acute viral hepatitis in the elderly is acute non-A, non-B hepatitis (48.7%), followed by acute hepatitis in HBsAg carrier (44.7%) and acute type B hepatitis (7.9%). Acute hepatitis in HBsAg carrier is the most common etiology in the young and middle-aged patients. Gastric flu, deep or tea colored urine and fatigue-weakness are the common clinical presentations. In conventional liver function tests, serum levels of GPT and albumin tended to be lower in the elderly patients. Overall, 25% of acute viral hepatitis in the elderly were complicated with fulminant hepatic failure or subacute hepatic failure and 18.4% died. The prevalence of fulminant or subacute hepatic failure and the mortality in the elderly were significantly higher than those in the younger patients.

The Helicobacter genus includes Gram negative bacteria which were originally considered to belong to the Campylobacter genus. They have been classified in a separate genus since 1989 because they have different biochemical characteristics, with more than 24 species having been identified and more still being studied.H. pylori is the best known. It has an important etiopathogenic role in peptic ulcer disease and gastric cancer. Enterohepatic Helicobacters (EHH) other than H. pylori colonize the bowel, biliary tree and liver of animals and human beings with pathogenic potential. The difficulties existing to correctly isolate these microorganisms limit the description of their true prevalence and of the diseases they cause. Many studies have tried to discover the different clinical implications of EHH. Diseases like chronic liver disease, autoimmune hepatitis, hepatocarcinoma, autoimmune hepatobiliary disease, biliary lithiasis, cholangiocarcinoma and gallbladder cancer, Meckel´s diverticulum, acute appendicitis and inflammatory bowel disease have been related with different EHH species with different results, although their prevalence is greater than in healthy subjects. However, these data are currently not sufficient to draw definitive conclusions. Finally, the best known role of EHH in bowel disease is production of acute and chronic diarrhea pictures initially referred to as Campylobacter. H. pullorum has been identified in patients with acute gastroenteritis. The correct identification of EHH as producers of infectious gastroenteritis is found in its antibiotic susceptibility. It is generally macrolide-susceptible and quinolone-resistant.
