Abstract Background: Hepatitis C virus is a major global health problem estimated to infect over 170 million people globally with the most common route of infection being injecting drug use (IDU). Treatment for HCV infection has traditionally been shown to be genotype specific; however the available drugs are still expensive and out of reach in many developing countries. To improve on monitoring, there is need to continuously document the genotypic burden and epidemiology in different populations arises. Objectives: This study aimed to determine the circulating genotypes and link the data to the socio-demographics of injecting drug users in Kilifi County along the Kenyan coastline. Methods: Using a random sampling method, this was a cross-sectional prospective study conducted among 127 injecting drug users, whereby ethical clearance was sought from Kenyatta National Hospital/ University of Nairobi Ethical and Research review committee (KNH/UON-ERC), and Reference number P366/07/2017 on 25 th September 2017. Serology for HCV was done followed by nucleic acid amplification and eventual genotyping. Socio-demographic data was collected using questionnaire administered at the sites. Results: A total of 28 (23 males and 5 females) samples out of 127 samples were positive for HCV giving a prevalence of 22.1%. The modal age group was 25- 49 years. Of the positive samples, 11 were amplified by PCR, all from the male IDUs. Prevalent genotypes included genotype 1a (13%) and genotype 4a (87%). Both genotype 1a and 4a were only found in males. Conclusion: Although it is the first time to report HCV4a in Kilifi town and Mtwapa as compared to Watamu and Malindi which had both HCV1a and HCV4a. Tourists born in countries where HCV prevalence is high are supposed to be screened before accessing entry to Kilifi County. No clinical trial was conducted. The study reveals the burden of HCV infection among IDUs in Kilifi County. The Government should formulate policies for intervention on testing and treatment of HCV in Kilifi County targeting IDUs in order to minimize spread to other populations.

The objective of this study was to estimate the prevalence of hepatitis C virus (HCV) infection and co-infection with HIV among injecting drug users (IDUs) in Togliatti City, Russia. Unlinked anonymous cross-sectional survey of IDUs recruited from community settings, with oral fluid sample collection for HCV and HIV antibody (anti-HCV, anti-HIV) testing, was carried out. The anti-HCV prevalence was 87% (357/411), anti-HIV prevalence 56% (234/418), and 93% (214/230) of HIV-positive IDUs were co-infected with HCV. Only 23% (94/411) of those HCV positive self-reported as such. In an adjusted model, increased odds of HCV positivity were associated with needle and syringe, as well as injecting paraphernalia sharing in the last four weeks. IDUs injecting more than once with the same needle also had raised odds. There were no marked associations between HCV positivity and the duration of injecting or age group. Almost all IDUs were HCV positive, and almost all HIV-positive IDUs were HCV co-infected. There is an urgent need to maximize syringe distribution coverage, develop health promotion targeting HCV prevention for IDUs, and improve access among IDUs to treatments for HIV and HCV infection.

Hepatitis C Virus is an important cause of preventable morbidity and mortality among Injecting Drug Users worldwide. The aim of this study is to determine the prevalence and correlations of HCV infection among IDUs in Saudi Arabia. A point cross-sectional survey was conducted between May 2012 and Nov 2012 to determine hepatitis C viral antibodies serological status using venous blood among IDUs (N=300) accessing care at Al-Amal Hospital in the Kingdom of Saudi Arabia, as well as to determine clinical correlates of hepatitis C infection among the Injecting Drug Users. There was an overall HCV prevalence of 42.7% among IDUs studied. Low level primary education, single marital status, being unemployed and commencing Injecting Drugs beyond the age of 15 years have higher specific prevalence of HCV among IDUs population. There was statistically significant association between clinical assessments of the participants who were abusing drugs generally, dependent on drugs, specifically abusing cocaine, amphetamines, opioids, cannabinoids and alcohol with HCV antibodies seropositivity. There was no statistical significant relationship between drug induced sleep/sexual disorder and psychosis/delusion with HCV seropositivity. This study demonstrated a relatively high prevalence of HCV among IDUs in KSA. Targeted public health preventive strategies are necessary to halt the spread of HCV among IDUs in KSA. The resultant benefits of these will include reduction in morbidity and mortality as well as improved socioeconomic wellbeing of the IDU’s population.

SUMMARYSurveillance reports and prevalence studies have indicated that injecting drug users (IDUs) contribute more to the hepatitis C epidemic in the United Kingdom than any other risk group. Information on both the prevalence and incidence of hepatitis C in IDUs is therefore essential to understanding the epidemiology of this infection. The prevalence of hepatitis C in specimens from the Unlinked Anonymous Prevalence Monitoring Programme collected in 1995, 1996, 1998, 1999, 2000, and 2001 was determined using residual syphilis serology specimens from IDUs attending 15 genitourinary medicine (GUM) clinics in and outside London. These specimens were tested for antibodies to hepatitis C virus (anti-HCV). Using this cross-sectional design, anti-HCV-negative specimens were tested for HCV RNA to identify incident infections during the ‘window’ period of infection, and thus to estimate HCV incidence. Results of the multivariable analysis showed that there was marked variation in prevalence by clinic (P<0·0001) and age (P<0·0001). Overall the majority of infections were in males and the overall prevalence in injectors declined over the study period from 36·9% to 28·7%. The annual incidence in these injectors was estimated as being 3·01% (95% CI 1·25–6·73). Over the study period HCV incidence decreased by 1·2% per year. Genotyping of the incident infections identified the most common genotype as type 1 with type 3 being more frequently seen after 1998. Of the prevalent infections, genotype 1 was the most common. The study has confirmed a higher prevalence of anti-HCV in IDUs in the London area compared to those outside London. How representative of the current injecting drug user population are IDUs attending GUM clinics is unclear. Even so, such studies allow prevalence and incidence to be estimated in individuals who have ever injected drugs and inform ongoing public health surveillance.
