The impact of hepatitis C virus infection on methadone maintenance treatment
1Digestive Specialists, Inc., Kettering Medical Center, OH 45429, USA.
Abstract:
Hepatitis C virus infection is now recognized as a common and serious complication of injection drug use and will be encountered frequently in methadone maintenance patients. Approximately 1.8% of the United States population, or 3.9 million persons, are infected with hepatitis C virus. A majority of acute hepatitis C virus infections are associated with injection drug use, and 64-88% of injection drug users in seroprevalence studies have antibodies to hepatitis C. Hepatitis C virus infection is almost always chronic, and alcohol use increases the clinical severity. Therapy with interferon and ribavirin will induce long-term remission in up to 43% of patients with hepatitis C virus infection. Proper diagnosis and treatment of hepatitis C virus infection will be indicated for many patients in methadone programs and will require considerable resources.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
