Current Issues in the Management of Hepatitis A and B
ISSUE: SEPTEMBER, 2006 Five hepatotropic viruses have been identified as causes of distinct types of hepatitis called hepatitis A, B, C,D, and E. Hepatitis A virus (HAV) and hepatitis E virus are enterically transmitted agents and cause only acute disease, while hepatitis B virus (HBV),hepatitis C virus, and hepatitis D virus are blood-borne agents and may produce both acute and chronic disease.

ISSUE: SEPTEMBER, 2006 Immunization against vaccine-preventable
hepatitis in the United States is appallingly low. This is a particularly acute problem for those who have or are at risk for HIV infection; they are also at high risk for the acquisition
of hepatitis A virus (HAV) and hepatitis B
virus (HBV).

Update on the Management of Hepatitis C
ISSUE: SEPTEMBER, 2005 Recent advances have improved our understanding of the hepatitis C virus (HCV)
and its treatment. Researchers have identified important interactions among
HCV, hepatic steatosis, and insulin resistance. Viral kinetic data have afforded
insight into the mechanism of action of ribavirin.

Hepatitis C: Transmission To Treatment
ISSUE: SEPTEMBER, 2004 Phylogenetic analyses suggest that hepatitis C virus (HCV) infection first appeared in humans in sub-Saharan Africa and southeastern Asia some 2,000 years ago. Further studies indicate that HCV reached the United States around 1910, just as soldiers returned home from the Spanish-American War. Hepatitis C spread primarily
through transfusion of contaminated blood products and injection drug use.

Management of Patients Coinfected With HIV & Hepatitis C Virus
ISSUE: SEPTEMBER, 2004 In the United States, between 800,000 and 900,000 people live with human immunodeficiency virus (HIV); of these, up to 25% may be coinfected with the hepatitis C virus (HCV). In those HIV clinic populations where intravenous
(I.V.) drug use is the most common cause of HIV infection, the prevalence of HCV is estimated to be 50% to 90%, and among patients also suffering from hemophilia, the rate is >50%.
