RESUMO
OBJECTIVES: Long-term monitoring of the mutual effects of chronic viral hepatitis C (VHC) treatment and tailored addiction treatment. In 2016, the World Health Organization (WHO) published an action plan to eliminate viral hepatitis C globally by 2030. People who inject drugs (PWID) are a key population that needs increased attention and care. Two decades before the announcement of the WHO plan for the global elimination of HCV (hepatitis C virus), the Remedis Medical Facility, where the study was conducted, established a “Comprehensive Care Program for patients with substance use disorders and addictive behaviour”. METHODS: We evaluated all patients who were in the methadone program as of 1 March 2020, regardless of OST duration, OST dosage, age or gender. Their epidemiological and demographic data obtained during a structured clinical interview and laboratory test results were analysed. RESULTS: Of 24 patients on methadone substitution therapy, 12 (50%) were anti-HCV negative before starting OST. None of them became newly infected with hepatitis C virus (HCV) during OST. The remaining 12 of the study patients were anti-HCV positive. Ten of them have already undergone successful treatment for viral hepatitis. Two patients were re-infected with HCV. CONCLUSION: The presented work confirms the high efficacy of chronic VHC treatment among PWID in inducing suitable conditions. We consider combination of HCV infection treatment and targeted tailored addiction treatment as a starting point for achieving control over the HCV epidemic in the Czech Republic, with a possible positive impact on other blood-borne infections related to risky behaviour.

INTRODUCTION: Aim of the study was to determine risk behaviour and HIV prevalence among commercial sex workers (CSWs) and intravenous drug users (IDUs) in streets of Bratislava and B. Bystrica, SR. METHODS: HIV antibodies were tested from saliva using ELISA test. Anonymous questionnaire was completed. RESULTS: 121 persons (61 men and 60 women) were involved in the sociological study. Mean age of the participants was 21.9 years. 185.1% of subjects were from Bratislava. 108 participants were tested for the presence of HIV-antibodies, one was confirmed HIV-positive (0.82%). In the past 47.9% of participants and 22.3% of their partners were tested for the presence of HIV-antibodies. 10.8% of subjects proclaimed that they suffered from other sexually transmitted infection (STI) in the past HIV testing of participants significantly correlated with the testing for other STI (p<0.002) as well as with HBV/HCV (p<0.001). 58 participants were using tattooing (47.9%). 46.3% of all participants never used condoms with partners. 31.4% of respondents proclaimed disruption of condom during sexual intercourse. Significant correlation was found between testing of participants for other STI and usage of condoms with their partners (p<0.013). Women used condoms more often by sexual contacts with partners than men used condoms (p<0.094). They were also significantly more tested for other STI in the past (p<0.021) and they suffered from other STI more often than men (p<0.033). 26.5% of person--only women--were involved in commercial sex work. 93.5% of them were taking drugs as well, 21.8% suffered for other STI in the past They were working in sex business on average for 26 months. The average number of their clients per week was 12.3. CSWs used condoms more often with clients than with partners. 98.2% of all participants were taking drugs, 93% of them intravenously. 24.6% of IDUs always used new or their own needles and syringes, while 69.4% shared equipments with the other users. IDUs drug users used condoms significantly less often with their partners than did CSWs (p<0.006). CSWs were significantly more often tested for other STI (p<0.001) and they also more often suffered for other STI than IDUs (p<0.045). CONCLUSION: More effort should be done to decrease risk behaviour revealed in the groups of CSWs and drug users.
