Reproductive tract infections (RTIs) among married non-pregnant women living in a low-income suburb of Beirut, Lebanon.

INTRODUCTION: This study aimed to identify reproductive tract infections (RTIs) in married, non-pregnant women, aged 18 to 49 years, living in a low-income suburb of Beirut, and to investigate the relationship between demographic and socioeconomic factors and these infections. METHODOLOGY: Among 1,015 women recruited for the study, 502 were found eligible and 441 were medically examined. Appropriate specimens were collected for Nisseria gonorrhea, Chlamydia trachomatis, Trichomonas vaginalis, candidiasis, and bacterial vaginosis. RESULTS: The results showed a relatively high prevalence of RTIs (28.2%). The prevalence rates of different agents were as follows: 22.9% of the women were positive for T. vaginalis, 8.8% for candidiasis, 4.5% for bacterial vaginosis, and 1% for N. gonorrhea; none of the women were positive for C. trachomatis. Regression analysis showed that women between the ages of 30 and 39 were twice more likely to have T. vaginalis as compared to younger women. Furthermore, women whose husbands were taxi drivers were at higher risk of acquiring T. vaginalis (OR = 2.2) as compared with women whose husbands occupation was listed as skilled/unskilled. This conclusion can be drawn for the odds of developing any RTI (OR = 2.15). Moreover, those participants with the lowest income were twice as likely to have any RTI compared to those with higher incomes. CONCLUSIONS: This study shows a relatively high prevalence of RTIs (T. vaginalis mainly). It urges further in-depth research on cultural practices and economic factors to understand the pattern of sexual behavior in this community.

Hepatitis B virus and hepatitis C virus infections among female sex workers and men who have sex with men in Lebanon: prevalence, risk behaviour and immune status.

BACKGROUND: The aim of our study was to study the prevalence of and the risk behaviours associated with the hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among two high-risk groups: female sex workers (FSW) and men who have sex with men (MSM). Furthermore, since vaccination is a key component of HBV prevention programs, the immune status of HBV infection in these two high-risk groups was evaluated. METHODS: Participants included in this study were part of a bio-behavioural surveillance study done to assess HIV prevalence among four vulnerable groups in Lebanon. Participants were recruited using a respondent-driven sampling method. The total number of eligible participants were 101 MSM and 103 FSW. Blood samples were collected as dried blood spots and then eluted to be tested for HCV, HBV and HIV by enzyme-linked immunosorbent assay. RESULTS: None of the 204 individuals tested has been exposed to HCV. In the 101 MSM, only one (0.99%) was an HBsAg carrier and one (0.99%) was confirmed as anti-HIV-positive. Among FSW, 30% showed they were immune to HBV compared with only ~10% among MSM. The distribution of socio-demographic characteristics and potential risk factors in both groups were shown. CONCLUSION: Our results highlight the urgent need to raise awareness among FSW and MSM and their health care providers of the availability and benefits of HBV vaccination in Lebanon. In addition, and due to the absence of vaccines against HCV and HIV, education programs aiming at behavioural changes should be intensified.

Distribution of hepatitis C virus genotypes among injecting drug users in Lebanon.

BACKGROUND: The aim of this study is to determine the prevalence of anti-HCV among injecting drug users (IDUs) in Lebanon, to establish the current prevalence of HCV genotypes in this population and to determine whether demographic characteristics and behavioral variables differ between participants who were HCV-RNA positive and those who were HCV-RNA negative or between the different genotypes. Participants were recruited using respondent-driven sampling method. The blood samples were collected as dried blood spots and then eluted to be tested for HCV, HBV and HIV by ELISA. Anti-HCV positive samples were subjected to RNA extraction followed by qualitative detection and genotyping. RESULTS: Among 106 IDUs, 56 (52.8%) were anti-HCV-positive. The two groups did not differ in terms of age, marital status, and nationality. As for the behavioral variable, there was a trend of increased risky behaviors among the HCV-RNA positive group as compared to the HCV-RNA negative group but none of the variables reached statistical significance. Half (50%) of the 56 anti-HCV-positive were HCV-RNA positive. Genotype 3 was the predominant one (57.1%) followed by genotype 1 (21%) and genotype 4 (18%). CONCLUSIONS: The predominance of genotype 3 seems to be the predominant genotype among IDUs in Lebanon, a situation similar to that among IDUs in Western Europe. This study provides a base-line against possible future radical epidemiological variant that might occur in IDUs.

Prevalence of antibodies to human immunodeficiency virus (HIV), hepatitis B and hepatitis C and risk factors in prisoners in Lebanon.

BACKGROUND: People admitted to correctional facilities often have a history of risky behaviours which frequently lead to transmission of blood-borne viruses, such as human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV). Our aim was to determine the prevalence of HIV, HBV and HCV infections among prisoners in Lebanon. METHODOLOGY: Conducted between August 2007 and February 2008 in Roumieh Prison, Lebanon, the study included a total of 580 male prisoners aged 16 and above who were randomly selected from four prison blocks. Peripheral blood was collected by a finger prick, blotted onto high-quality filter paper, dried and later eluted to be tested for markers of HIV, HBV and HCV infections. RESULTS: A significantly higher seroprevalence of HBV (2.4%) and HCV (3.4%) was found among prisoners compared to the seroprevalence of these virus infections reported in the general Lebanese population (< 1% for HBV and HCV). Only one of the 580 prisoners tested (0.17%) was confirmed as anti-HIV-positive. The majority (89%) of anti-HCV-positive prisoners had a history of previous imprisonment and were injecting drug users (IDUs). Tattooing was also associated with HCV transmission: all nine anti-HCV-positive prisoners had tattoos compared to only 60% who were anti-HCV-negative. Only HCV genotypes 1 and 3 were detected. CONCLUSIONS: We provide evidence for an outbreak of HCV and HBV occurring in Roumieh prison. In addition to vaccinating prisoners against HBV, collaborations should develop between the prison's administration, academic institutions, and community-based organizations to provide HCV prevention services within the prisons.
