Behavior of injection drug users increases the risk for an HIV epidemic.

A Qualitative Assessment of Decisions Affecting Contraceptive Utilization and Fertility Intentions among HIV-Positive Women in Soweto, South Africa

The HIV epidemic in sub-Saharan Africa disproportionately affects women of reproductive age. The increasing provision of Highly Active Anti-Retroviral Therapy (HAART) with improved prognosis and maternal-fetal outcomes calls for an understanding of fertility planning for HIV-positive women. We describe the effect of HIV and HAART on pregnancy desires and contraceptive use among HIV-positive women in Soweto, South Africa. Focus group discussions and in-depth interviews were conducted with 42 HIV-positive women of reproductive age. Analysis was performed using ATLAS-ti (ATLAS-ti Center, Berlin). Emergent themes were impact of HIV diagnosis on pregnancy intentions; factors affecting contraceptive uptake including real and normative side effects, body image, and perceived vaginal wetness; and the mitigating influence of partnership on both pregnancy intentions and contraceptive use. Routine counseling about pregnancy desires and contraception should be offered to HIV-positive women.

Seroprevalence and correlates of HIV, syphilis, and hepatitis B and C virus among intrapartum patients in Kabul, Afghanistan.

BackgroundLittle current information is available for prevalence of vertically-transmitted infections among the Afghan population. The purpose of this study is to determine prevalence and correlates of human immunodeficiency virus (HIV), syphilis, and hepatitis B and C infection among obstetric patients and model hepatitis B vaccination approaches in Kabul, Afghanistan.MethodsThis cross-sectional study was conducted at three government maternity hospitals in Kabul, Afghanistan from June through September, 2006. Consecutively-enrolled participants completed an interviewer-administered survey and whole blood rapid testing with serum confirmation for antibodies to HIV, T. pallidum, and HCV, and HBsAg. Descriptive data and prevalence of infection were calculated, with logistic regression used to identify correlates of HBV infection. Modeling was performed to determine impact of current and birth dose vaccination strategies on HBV morbidity and mortality.ResultsAmong 4452 women, prevalence of HBsAg was 1.53% (95% CI: 1.18 – 1.94) and anti-HCV was 0.31% (95% CI: 0.17 – 0.53). No cases of HIV or syphilis were detected. In univariate analysis, HBsAg was associated with husbands level of education (OR = 1.13, 95% CI: 1.01 – 1.26). Modeling indicated that introduction of birth dose vaccination would not significantly reduce hepatitis-related morbidity or mortality for the measured HBsAg prevalence.ConclusionIntrapartum whole blood rapid testing for HIV, syphilis, HBV, and HCV was acceptable to patients in Afghanistan. Though HBsAg prevalence is relatively low, periodic assessments should be performed to determine birth dose vaccination recommendations for this setting.

Prevalence of HIV, hepatitis B and hepatitis C and associated risk behaviours amongst injecting drug users in three Afghan cities

BACKGROUND HIV amongst injecting drug users (IDUs) has been described in Kabul but little data exists for other Afghan cities. We assessed HIV, hepatitis B virus (HBV), and C virus (HCV) prevalence and associated risk behaviours amongst IDUs in Hirat, Jalalabad, and Mazar-i-Sharif, Afghanistan. METHODS Consented participants reporting injecting drugs within the previous 6 months completed interviewer-administered questionnaires and testing for HIV, hepatitis C antibody (HCV Ab), and hepatitis B surface antigen (HBsAg). Logistic regression was used to determine characteristics associated with each infection. RESULTS Of 623 participants, most (98.7%) were male. Prevalence of HIV, HCV, and HBV was 1.8% (95% CI: 0.88-3.2), 36.0% (95% CI: 33-41), and 5.8% (95% CI: 3.9-7.6), respectively. All HIV cases and highest HCV prevalence were detected in Hirat; HBV prevalence was highest in Jalalabad. Amongst male IDUs, 62.9% had been imprisoned, of whom 17.2% (n=66) injected in prison. High risk behaviours were common; 30.2% reported needle sharing in the last 6 months, 23.1% reported sex with another male, and 50.4% reported paying females for sex. Behaviours varied significantly by site; generally, Hirat participants reported fewer sexual risk behaviours. Sex with other males was negatively associated with both HBV and HCV in multivariate logistic regression analysis; no injecting behaviours were associated with both HBV and HCV. CONCLUSIONS Whilst HIV prevalence is low, HCV prevalence and high risk behaviours were common in these populations. Regional variations should be considered in programming to prevent transmission of HIV and viral hepatitis amongst IDUs in Afghanistan.

Complex Emergencies, HIV, and Substance Use: No “Big Easy” Solution

During the last 2 years, the world has witnessed complex emergencies in virtually every corner of the world, including the tsunami in Indonesia; wars and armed conflicts in Afghanistan, Iraq, the Balkans, Sudan, Somalia, and the Congo; volcanic eruptions in Comoros and El Salvador; hurricanes in the southern United States, Caribbean, and Central America; floods in Eastern Europe, South Asia, and Africa; and earthquakes in Peru and Pakistan. Complex emergencies—created by natural or technological disasters, epidemics, or conflicts—are typified by a severe disruption in families, communities, and societies that overwhelms the normal coping capacities of the affected people (Toole, 1999). Although it is widely recognized that complex emergencies create any number of intense hardships such as enormous death tolls, injuries, communicable diseases, famine, homelessness, displacement, unemployment, psychological traumas, and rape, only in recent years has drug abuse1 been recognized as a potential consequence of some complex emergencies. Substance use can quickly reach epidemic proportions in various settings in response to posttraumatic stress, severe disruption of socioeconomic situations, or prolonged instability or hardships within societies and governments. Increased substance use can also be exacerbated by changing market factors such as the sudden availability of illicit drugs in societies with previously limited exposure and the decreased purity or increased price of opiates, which can inadvertently lead to transitions from smoking, snorting, or inhalation to injection drug use, which is a more efficient route of drug administration (Strathdee et al., 2003). Similarly, it has been known for centuries that natural disasters and armed conflicts are the harbinger of myriad communicable diseases such as measles, malaria, cholera,

Contraceptive Utilization and Pregnancy Termination Among Female Sex Workers in Afghanistan

BACKGROUND To determine the prevalence and correlates of prior pregnancy termination and unmet need for contraception among female sex workers (FSWs) in Afghanistan. METHODS FSWs in Jalalabad, Kabul, and Mazar-i-Sharif were recruited between June 2006 and December 2007 through outreach programs. Participants completed an interviewer-administered survey describing demographics, behaviors associated with risk of sexually transmitted infections (STIs) and unplanned pregnancy, and medical history. Correlates of prior pregnancy termination and current unmet need for contraception were assessed with logistic regression analysis, controlling for site. RESULTS Of 520 FSWs, most (82.3%) had been pregnant at least once (mean 4.9 ± 2.7, range 1-17), among whom unplanned pregnancy (36.9%) and termination (33.2%) were common. Jalalabad participants were more likely to report both prior unplanned pregnancy (60.6% vs. 48.3% in Kabul or 20.7% in Mazar, p < 0.001) and prior termination (54.9% vs. 31.8% in Kabul or 26.8% in Mazar, p < 0.001). Most FSWs (90.0%) stated pregnancy was not currently desirable, and 85.2% were using contraception. Unmet need for contraception (14.7% of participants) was positively associated with having sold sex outside their city of residence (adjusted odds ratio [AOR] 1.88, 95% confidence interval [CI] 1.28-2.77) and inversely associated with illicit drug use (AOR 0.41, 95% CI 0.31-0.53). CONCLUSIONS Although FSWs in Afghanistan report high rates of contraceptive use, unplanned pregnancy is common. Reproductive health services should be included in programming for FSWs to reduce unplanned pregnancies and to reduce HIV/STI risks.

HIV, hepatitis B, and hepatitis C prevalence and associated risk behaviors among female sex workers in three Afghan cities.

Objective:To assess prevalence of HIV, syphilis, and hepatitis B (HBV) and C virus (HCV) and associated risk behaviors among female sex workers (FSWs) in three Afghan cities. Design:Cross-sectional prevalence assessment. Methods:Consented FSWs from Jalalabad, Kabul, and Mazar-i-Sharif completed an interviewer-administered questionnaire, pretest and posttest counseling, and rapid and confirmatory testing for HIV, HCV, HBV, and syphilis. Logistic regression was used to detect correlates associated with HBV infection. Results:Of 520 participants, median age and age of initiating sex work were 29 and 23 years, respectively, and the median number of monthly clients was 12. Few FSWs reported ever having used illicit drugs (6.9%) or alcohol (4.7%). Demographic and risk behaviors varied significantly by enrollment site, with Kabul FSWs more likely to report sexually transmitted infection symptoms, longer sex work duration, and sex work in other cities. Prevalence of HIV was 0.19%, HCV was 1.92%, and HBV was 6.54%, with no cases of syphilis detected. HBV was independently associated with at least 12 clients monthly [adjusted odds ratio (AOR) = 3.15, 95% confidence interval (CI) 1.38–7.17], ever using alcohol (AOR = 2.61, 95%CI 1.45–4.69), anal sex (AOR = 2.42, 95%CI 1.15–5.08), and having children (AOR = 2.12, 95%CI 1.72–2.63) in site-controlled multivariable analysis. Conclusion:Although prevalence of HIV, HCV, and syphilis is currently low in these three Afghan cities, risky sexual practices were common and associated with HBV. Programming inclusive of voluntary testing for HIV, viral hepatitis, and sexually transmitted infections, hepatitis vaccination, substance abuse prevention, and condom promotion for both FSWs and clients should be pursued in Afghanistan.

Prevalence and correlates of HIV, syphilis, and hepatitis B and C infection and harm reduction program use among male injecting drug users in Kabul, Afghanistan: A cross-sectional assessment

BackgroundA nascent HIV epidemic and high prevalence of risky drug practices were detected among injecting drug users (IDUs) in Kabul, Afghanistan from 2005-2006. We assessed prevalence of HIV, hepatitis C virus (HCV), hepatitis B surface antigen (HBsAg), syphilis, and needle and syringe program (NSP) use among this population.MethodsIDUs were recruited between June, 2007 and March, 2009 and completed questionnaires and rapid testing for HIV, HCV, HBsAg, and syphilis; positive samples received confirmatory testing. Logistic regression was used to identify correlates of HIV, HCV, and current NSP use.ResultsOf 483 participants, all were male and median age, age at first injection, and duration of injection were 28, 24, and 2.0 years, respectively. One-fifth (23.0%) had initiated injecting within the last year. Reported risky injecting practices included ever sharing needles/syringes (16.9%) or other injecting equipment (38.4%). Prevalence of HIV, HCV Ab, HBSAg, and syphilis was 2.1% (95% CI: 1.0-3.8), 36.1% (95% CI: 31.8-40.4), 4.6% (95% CI: 2.9-6.9), and 1.2% (95% CI: 0.5-2.7), respectively. HIV and HCV infection were both independently associated with sharing needles/syringes (AOR = 5.96, 95% CI: 1.58 - 22.38 and AOR = 2.33, 95% CI: 1.38 - 3.95, respectively). Approximately half (53.8%) of the participants were using NSP services at time of enrollment and 51.3% reported receiving syringes from NSPs in the last three months. Current NSP use was associated with initiating drug use with injecting (AOR = 2.58, 95% CI: 1.22 - 5.44), sharing injecting equipment in the last three months (AOR = 1.79, 95% CI: 1.16 - 2.77), prior incarceration (AOR = 1.57, 95% CI: 1.06 - 2.32), and greater daily frequency of injecting (AOR = 1.40 injections daily, 95% CI: 1.08 - 1.82).ConclusionsHIV and HCV prevalence appear stable among Kabul IDUs, though the substantial number having recently initiated injecting raises concern that transmission risk may increase over time. Harm reduction programming appears to be reaching high-risk drug user populations; however, monitoring is warranted to determine efficacy of prevention programming in this dynamic environment.

Patient-provider communication and reproductive health among HIV-positive women in Rio de Janeiro, Brazil.

OBJECTIVE To qualitatively assess the influence of patient-provider communication on contraceptive choice among HIV-positive women in the context of universal antiretroviral therapy (ART) access. METHODS Focus group discussions (FGD; n=3), in-depth (IDI; n=15) and freelist interviews (FLI; n=36) were conducted with HIV-positive women aged 18-40 years recruited from public health units in Rio de Janeiro/Brazil. RESULTS Of 70 participants, 49 used ART and the median time since HIV diagnosis was 6 years (range: 1-18). The majority of participants (71.4%) reported some degree of dissatisfaction with their health providers (usually lack of open dialogue) and a few reported experiences of stigma/prejudice during appointments. Intra, interpersonal and social factors modulated behaviors and reproductive health decisions, and those issues were rarely addressed by providers during HIV clinical care. CONCLUSION Despite dramatic increases in survival and life quality after universal ART implementation in Brazil, reproductive health issues are neglected by multiple cadres of HIV health providers. Communication on reproductive health issues remains fragmented and potentially contradictory, compromising care in these settings. PRACTICE IMPLICATIONS Adequate provider training to address reproductive health-related issues in a comprehensive, culturally sensitive manner and improved integration of HIV and reproductive health care are urgently needed in this setting.

Drug use and harm reduction in Afghanistan

Opium has been cultivated in Afghanistan since 1100 A.D., although production has steadily increased since 1979. Currently, Afghanistan produces three-quarters of the global opium supply, with injection drug use and HIV currently following the opium trade route through Central Asia. Although systematic studies are lacking, heroin use appears to be on the rise in Afghanistan. The purpose of this paper is to briefly provide historical background and current statistics for drug production and use in Afghanistan, to discuss the new governments policies towards problem drug use and available rehabilitation programs, and to assess Afghan harm reduction needs with consideration of regional trends.
