Experts Urge Screening of Veterans for Hepatitis C
Nov. 11, 1999 (Dallas) -- Experts at the 50th Annual Meeting of American Association for Liver Disease reported that more and more veterans -- particularly Vietnam-era veterans -- will die as a result of infection with hepatitis C.
Currently about 3.5 million veterans receive their medical care at Veterans Affairs (VA) Medical Centers. Megan Briggs, MPH, says a screening study of veterans treated at an outpatient clinic at the San Francisco VA Medical Center suggests that as many as 18% of veterans are infected with hepatitis C, a virus that lingers undetected for decades but may suddenly flare up. When the virus becomes active it attacks the liver, causing scarring and eventually cirrhosis. Patients with cirrhosis due to hepatitis C are also at an increased risk of developing liver cancer. Cirrhosis and liver cancer often lead to the need for a liver transplant.
In recent years, the VA has become aware of a growing number of hepatitis C cases among both its outpatient population and hospitalized veterans, says Theresa L. Wright, MD, chief of gastroenterology at the VA Medical Center in San Francisco. Wright and Briggs co-authored a study based on screening of veterans receiving outpatient care.
Wright says that among the risk factors associated with hepatitis C infection, "IV drug abuse just overwhelmed all other factors." That's significant because the highest prevalence was found among "patients in their late 40's and early 50's -- the veterans of the Vietnam era." She says that, "it isn't simply a matter of having served in Vietnam but rather a timing thing: Vietnam coincided with the explosion of IV drug abuse in the U.S." Thus, it is the timing of service that links these veterans to the disease.
The link between Vietnam-era veterans and hepatitis C is compelling, according to a fact sheet from Samuel B. Ho, MD, assistant professor of medicine at the VA Medical Center, and University of Minnesota, Minneapolis. The sheet cites a VA tracking study that analyzed 95,000 hepatitis C tests from 173 VA centers and 600 VA associated clinics. That study found that Vietnam-era veterans account for about 64% of positive hepatitis C tests, he tells WebMD.
