Low level of transmitted HIV Drug resistance at two HIV care centres in Ghana: a threshold survey.

BACKGROUND: As access to antiretroviral therapy (ART) increases, the emergence and transmission of HIV drug resistant strains becomes a major problem. The World Health Organization (WHO) therefore recommends an initial minimum-resource method to signal when transmitted HIV drug resistance (HIVDR) requires action. OBJECTIVE: This survey sought to generate information on the presence of HIV drug-resistant strains in the locality where Ghana's ART for HIV was first introduced. METHODS: The Ghana HIVDR threshold survey (TS) was conducted and analyzed according to WHO strategy for surveillance of HIVDR in the Eastern Region of Ghana. Sixty (60) plasma specimens were collected from 2007 to 2009 by an unlinked anonymous method from HIV seropositive pregnant women, aged between 15 to24 years, who were with their first pregnancy and ART naive. Genotyping was done as follows; Ribonucleic acid (RNA) was extracted from the samples and the protease (PR) and reverse transcriptase (RT) genes amplified and sequenced. The sequences were then analyzed for HIV drug resistance mutations using Stanford University HIV Drug Resistance Database. RESULTS: Only two individuals were found with major HIVDR mutations: one each in the PR and RT genes. Thus the level of HIVDR in the study population in 2009 was classified as low (< 5%). CONCLUSION: As at February 2009, transmitted drug resistance was not a serious problem in the Eastern Region of Ghana. However, it is important to continue monitoring tHIVDR in order to understand the dynamics of the evolution of HIV drug resistance in the country.

Hepatitis C virus seroprevalence among mothers delivering at the Korle-Bu Teaching Hospital, Ghana.

OBJECTIVES: To determine the Hepatitis C virus (HCV) carrier rate among mothers, and to determine if selected sociodemographic characteristics are associated with HCV seropositivity. DESIGN: Maternity Unit of the Korle-Bu Teaching Hospital (KBTH). SETTING: A cross-sectional serological survey of mothers delivering at the KBTH. METHODS: Women who had singleton live births and fresh stillbirths in the two labour wards of the KBTH were randomly selected for screening from 1st March to 30th September, 2001. A structured pre-tested questionnaire was used by trained research assistants to collect and record data on medical and sociodemographic characteristics of the subjects. Maternal blood samples were taken and stored at the Public Health Reference Laboratory. The second generation Murex diagnostics ELISA kit was used to test the maternal sera for HCV antibodies. RESULTS: Sixteen (2.5%, 95% CI, 1.5-4.1%) of the 638 subjects were HCV seropositive. None of the medical and sociodemographic characteristics examined showed any association with HCV seropositivity. No subject or her sexual partner was a drug injector. CONCLUSION: The carrier rate of 2.5% of HCV infection found in this study is near the top end of the range found in unselected pregnant populations from other parts of the world. Knowing the prevalence rate of HCV infection in our pregnant population will help policy-makers on the cost effectiveness of available intervention measures.

HIV infection among sex workers in Accra: need to target new recruits entering the trade.

OBJECTIVE: Description of the epidemiology of HIV infection among sex workers (SW) in Accra, Ghana. METHODS: In all, 1013 SW working out of their homes ( seaters ) or finding customers in bars, hotels, brothels or on the street ( roamers ) were interviewed and tested for HIV. RESULTS: Overall, prevalence of HIV infection was nearly 50% (506 of 1013), varying from 26% (133 of 507) among the roamers to 74% (368 of 496) among the seaters. Profound differences were noted between these two categories of SW with regard to age, number of clients per day, price per instance of intercourse, condom use, and other characteristics. Respectively, 27% and 58% of roamers and seaters were infected with HIV within their first 6 months of sex work, despite a limited number of unprotected sex acts with seropositive clients. Independent risk factors for HIV infection varied between types of SW: age among the roamers; region of origin and duration of sex work among the seaters; number of clients per day, and presence of current or past genital ulcer and gonococcal cervicitis in both groups. CONCLUSION: In Accra, considerable heterogeneity exists in the population of SWs. In both categories of SW, new recruits become rapidly infected with HIV after entering the trade. The 25-fold higher prevalence of HIV among SWs than in the general adult population suggests that in Accra, as in many cities of West Africa, a high fraction of new cases of HIV infection continue to be acquired from SWs. Intervention programs targeting SW should be an essential component of national AIDS control strategies. Special efforts should be made to identify and offer preventive services to new sex workers.

Improvement of clinical algorithms for the diagnosis of Neisseria gonorrhoeae and Chlamydia trachomatis by the use of Gram-stained smears among female sex workers in Accra, Ghana.

BACKGROUND: Screening for cervical infection is difficult in developing countries. Screening strategies must be improved for high-risk women, such as female sex workers. GOAL: To evaluate the sensitivity and specificity of screening algorithms for cervical infection pathogens among female sex workers in Accra, Ghana. STUDY DESIGN: A cross-sectional study among female sex workers was conducted. Each woman underwent an interview and a clinical examination. Biologic samples were obtained for the diagnosis of HIV, syphilis, bacterial vaginosis, yeast infection, Trichomonas vaginalis, Neisseria gonorrhoeae, and Chlamydia trachomatis infection. Signs and symptoms associated with cervicitis agents were identified. Algorithms for the diagnosis of cervical infection were tested by computer simulations. RESULTS: The following prevalences were observed: HIV, 76.6%; N. gonorrhoeae, 33.7%; C. trachomatis, 10.1%; candidiasis, 24.4%; T. vaginalis, 31.4%; bacterial vaginosis, 2.3%; serologic syphilis, 4.6%; and genital ulcers on clinical examination, 10.6%. The best performance of algorithms were reached when using a combination of clinical signs and a search for gram-negative diplococci on cervical smears (sensitivity, 64.4%; specificity, 80.0%). CONCLUSIONS: In the algorithms, examination of Gram-stained genital smears in female sex workers without clinical signs of cervicitis improved sensitivity without altering specificity for the diagnosis of cervical infection.
