Gay, bisexual, and other men who have sex with men accessing STI clinics: Optimizing HIV PrEP implementation

Background

Gay, bisexual and other men who have sex with men (gbMSM) who attend STI clinics represent an easily accessible population for promoting HIV prevention interventions. We examined characteristics of gbMSM STI clinic attendees to identify those who could most benefit from pre-exposure prophylaxis (PrEP).

Setting

GbMSM STI clinic attendees in British Columbia (BC), Canada

Methods

A clinical electronic charting system of STI clinics in BC was used to identify gbMSM from 2004 to 2017. Incident HIV cases were defined as testers who had at least one HIV-negative test and a subsequent HIV-positive test. Seroconversion rates were calculated by risk factor variables and by year. Cox proportional hazards regression was used to identify independent predictors of HIV seroconversion.

Results

There were 9,038 gbMSM included, of whom 257 HIV seroconverted over the study period and 8,781 remained negative HIV testers, contributing 650.8 and 29,591.0 person-years to the analysis, respectively. The overall rate of seroconversion was 0.85 per 100 person-years (95% CI: 0.75–0.96). Incidence rates were higher among patients reporting >5 partners in the previous six months, inconsistent condom use, or having a partner living with HIV and who had a previous or concurrent diagnosis of rectal gonorrhea or rectal chlamydia. gbMSM presenting with two STIs such as rectal gonorrhea and syphilis (3.59/100 person-years [95%CI: 2.33–5.22]) or rectal chlamydia and syphilis (3.01/100 person-years [95%CI: 2.00–4.29]) had the highest incidence rates.

Conclusion

gbMSM with preceding or concurrent rectal STI diagnoses or syphilis had higher rates of HIV seroconversion. The data support the inclusion of specific STI diagnoses as an indication for PrEP.

Undisclosed HIV Status to Sex Partners and Its Unintended Consequences in the Era of Undetectable = Untransmittable

BACKGROUND

Adherence to antiretroviral therapy (ART) and sustained HIV suppression virtually eliminate HIV transmission, eg, having an undetectable viral load renders HIV untransmittable (U=U). Owing to the greatly reduced likelihood of HIV transmission when viral load is undetectable, we studied one behavioral ramification of adopting a U=U prevention strategy-not disclosing HIV status to sex partners.

SETTING

Cisgender men recruited through community outreach in the state of Georgia, USA.

METHODS

We examined HIV status disclosure to sex partners among 345 young (median age = 29 years) men receiving ART. Data were collected using computerized interviews, daily sexual behavior surveys over 28 days, unannounced pill counts for ART adherence, urine tests for drug use and urogenital health, and blood samples for HIV viral load.

RESULTS

One in 3 participants (34%) engaged in condomless anal/vaginal intercourse with an HIV-negative/unknown HIV status partner over 28 days. Average ART adherence was 76%, and one in 5 men had detectable HIV viral loads. Men who engaged in condomless sex with undisclosed partners demonstrated significantly less HIV disclosure to family and friends and had fewer enacted stigma experiences. Hierarchical regression models showed that endorsing U=U as a personal HIV prevention strategy predicted undisclosed condomless sex over and above substance use, HIV stigma experiences, disclosure to family and friends, ART adherence, and HIV viral load.

CONCLUSIONS

Interventions are needed to improve ART adherence and assist men living with HIV in their decisions to disclose HIV status to sex partners.

Acceptability of index partner HIV self-testing among HIV-positive clients in Malawi: A mixed methods analysis

OBJECTIVE

We sought to evaluate whether HIV-positive adults in Malawi were willing to distribute HIV self-testing (HIVST) kits to their sexual partners of unknown HIV status (index HIVST).

DESIGN

A mixed-methods study was nested within a larger HIVST trial conducted at 15 health facilities in Malawi. Exit surveys were conducted with HIV-positive adults during routine outpatient department visits to assess perceived acceptability of index partner HIVST versus standard partner referral slips that request partner(s) to attend the health facility. Individuals were included in the sub-analysis irrespective of date of HIV diagnosis or ART initiation (or non-initiation). In-depth interviews were conducted with a sub-sample of respondents.

RESULTS

404 HIV-positive adults completed a survey (159 male and 245 female); 21 completed in-depth interviews. Respondents reported feeling more comfortable distributing HIVST versus partner referral slips to their partners (90% vs. 81%) and expressed confidence that their partners would test using HIVST compared to referral slips (77% vs. 66%). Acceptability of HIVST did not vary by sex. Qualitative data revealed that index HIVST was perceived to be private, convenient, and may strengthen relationships by assisting in serostatus disclosure. There were minimal fears of adverse events. Reported barriers to index HIVST included lack of trust within the relationship and harmful gender norms.

CONCLUSIONS

HIV-positive clients were willing to distribute HIVST kits to their sexual partners of unknown serostatus. Additional studies are needed to evaluate use of HIVST by index partners, positivity, linkage to care, and adverse events related to index partner HIVST, such as coercion to test among index partners or interpersonal violence among index clients.

HIV-1 Transmission Patterns Within and Between Risk Groups in Coastal Kenya

HIV-1 transmission patterns within and between populations at different risk of HIV-1 acquisition in Kenya are not well understood. We investigated HIV-1 transmission networks in men who have sex with men (MSM), injecting drug users (IDU), female sex workers (FSW) and heterosexuals (HET) in coastal Kenya. We used maximum-likelihood and Bayesian phylogenetics to analyse new (N = 163) and previously published (N = 495) HIV-1 polymerase sequences collected during 2005-2019. Of the 658 sequences, 131 (20%) were from MSM, 58 (9%) IDU, 109 (17%) FSW, and 360 (55%) HET. Overall, 206 (31%) sequences formed 61 clusters. Most clusters (85%) consisted of sequences from the same risk group, suggesting frequent within-group transmission. The remaining clusters were mixed between HET/MSM (7%), HET/FSW (5%), and MSM/FSW (3%) sequences. One large IDU-exclusive cluster was found, indicating an independent sub-epidemic among this group. Phylodynamic analysis of this cluster revealed a steady increase in HIV-1 infections among IDU since the estimated origin of the cluster in 1987. Our results suggest mixing between high-risk groups and heterosexual populations and could be relevant for the development of targeted HIV-1 prevention programmes in coastal Kenya.

[Stigma and HIV: relevant for everyone]

Medical advances in the treatment of HIV over the last 35 years mean that people living with HIV (PLHIV) now have a life expectancy close to that of the general population. Further, when successfully treated, PLHIV cannot transmit the virus. Despite this, HIV-related stigma remains widespread, including within healthcare settings. Stigma is not a vague sociological notion but represents a real threat to public health, with repercussions for both PLHIV and HIV-negative individuals. Stigma has been shown to have a negative impact on HIV prevention, testing, access to health services, and on the healthcare management of PLHIV. Taking stigma into consideration is essential, both in meeting the medical and psycho-social needs of PLHIV and in order to effectively combat HIV/AIDS.

HIV testing, test results and factors influencing among infants born to HIV positive mothers in public hospitals of Mekelle City, North Ethiopia: a cross-sectional study

BACKGROUND

Timely infant testing for HIV is critical to ensure optimal treatment outcomes among exposed infants. While world health organization recommends HIV exposed infants to be tested between 4 to 6 weeks of age, in developing countries like Ethiopia, access to timely infant testing is still very limited. The study is intended to assess timely infant testing, testing for HIV at the 18th month, test results and factors influencing HIV positivity among infants born to HIV positive mothers in public hospitals of Mekelle, Ethiopia.

METHODS

A cross-sectional study design was employed on 558 HIV exposed infants, using consecutive sampling technique. A checklist was used to extract 4 years (January 2014-December 2017) secondary data, collected from January-April 2018. Data were analyzed using SPSS version 20, and binary logistic regression model was used to examine the association of independent variables with the outcome variables.

RESULTS

Timely infant testing for HIV accounted for 346(62.0%). Mothers who attended antenatal care (AOR: 2.77; 95% CI: 1.17, 6.55) and who were counselled on feeding options (AOR: 2.01; 95% CI: 1.11, 3.65) were strongly associated with timely infant testing. Poor maternal adherence status was associated with infants' HIV positivity at the 18th month of antibody test (AOR: 15.93; 95% CI: 2.21, 94.66). Being rural resident (AOR: 4.0; 95% CI: 1.23, 13.04), being low birth weight (AOR: 5.64; 95% CI: 2.00, 16.71) and not receiving ARV prophylaxis (AOR: 4.70; 95% CI: 1.15, 19.11) were positively associated with the overall HIV positivity.

CONCLUSIONS

A considerable proportion of exposed infants did not undergo timely testing for HIV. Antenatal care follow-up and counselling on feeding options were associated with timely infant testing. Mother's poor adherence status was associated with infant's HIV positivity at the 18th month of antibody testing. Being rural resident, being low birth weight, and not receiving ARV prophylaxis were the factors that enhance the overall HIV positivity. Timely infant testing, counselling on feeding options and adherence should be intensified, and prevention of mother-to-child transmission program in rural settings need to be strengthened.

Expanding the donor pool: Hepatitis C, hepatitis B and human immunodeficiency virus-positive donors in liver transplantation

Liver transplantation (LT) remains the best option for patients with end-stage liver disease but the demand for organs from deceased donors continues to outweigh the available supply. The advent of highly effective anti-viral treatments has reduced the number of patients undergoing LT for hepatitis C (HCV) and hepatitis B (HBV) related liver disease and yet the number of patients waiting for LT continues to increase, driven by an increase in the patients listed with a diagnosis of cirrhosis due to non-alcoholic steatohepatitis and alcohol-related liver disease. In addition, human immunodeficiency virus (HIV) infection, which was previously a contra-indication for LT, is no longer a fatal disease due to the effectiveness of HIV therapy and patients with HIV and liver disease are now developing indications for LT. The rising demand for LT is projected to increase further in the future, thus driving the need to investigate potential means of expanding the pool of potential donors. One mechanism for doing so is utilizing organs from donors that previously would have been discarded or used only in exceptional circumstances such as HCV-positive, HBV-positive, and HIV-positive donors. The advent of highly effective anti-viral therapy has meant that these organs can now be used with excellent outcomes in HCV, HBV or HIV infected recipients and in some cases uninfected recipients.

Perceptions of pregnancy occurring among HIV-serodiscordant couples in Kenya

BACKGROUND

Among HIV serodiscordant couples, most conception involves condomless sex and may confer a period with increased HIV transmission risk if HIV viral load is not suppressed and other precautions are not used. Safer conception strategies enable HIV serodiscordant couples to attain their pregnancy goals while markedly reducing this risk. We explored the perceptions and beliefs held by HIV serodiscordant couples and health care providers concerning pregnancy among HIV serodiscordant couples in Kenya and gathered their thoughts about how these might influence use of safer conception methods.

METHODS

We conducted 20 Key Informant Interviews (KIIs) with health care providers offering safer conception counseling and 21 In-Depth Interviews (IDIs) and 4 Focus Group Discussions (FGDs) with members of HIV serodiscordant couples with immediate pregnancy goals in Thika, Kenya. Data were analyzed using an inductive approach that identified two emergent themes: perceptions towards pregnancy among HIV serodiscordant couples and access to safer conception services.

RESULTS

The perceptions held by the community towards couples in HIV serodiscordant relationships having children were largely negative. The participants were aware of the increased HIV transmission risk to the HIV uninfected partners while trying to become pregnant. In the community, having biological children was cherished yet the majority of the couples shied away from accessing safer conception services offered at health facilities due to stigma and lack of knowledge of the existence of such services. Some providers had limited knowledge on safer conception strategies and services and consequently discouraged HIV serodiscordant couples from natural conception.

CONCLUSIONS

Negative perceptions towards HIV serodiscordant couples becoming pregnant has hindered access to safer conception services. Therefore, there is need to create a supportive environment for HIV serodiscordant couples with fertility intentions that normalizes their desire to have children and informs the community about the availability of safer conception services.

Risk of HIV transmission through condomless sex in serodifferent gay couples with the HIV-positive partner taking suppressive antiretroviral therapy (PARTNER): final results of a multicentre, prospective, observational study

BACKGROUND

The level of evidence for HIV transmission risk through condomless sex in serodifferent gay couples with the HIV-positive partner taking virally suppressive antiretroviral therapy (ART) is limited compared with the evidence available for transmission risk in heterosexual couples. The aim of the second phase of the PARTNER study (PARTNER2) was to provide precise estimates of transmission risk in gay serodifferent partnerships.

METHODS

The PARTNER study was a prospective observational study done at 75 sites in 14 European countries. The first phase of the study (PARTNER1; Sept 15, 2010, to May 31, 2014) recruited and followed up both heterosexual and gay serodifferent couples (HIV-positive partner taking suppressive ART) who reported condomless sex, whereas the PARTNER2 extension (to April 30, 2018) recruited and followed up gay couples only. At study visits, data collection included sexual behaviour questionnaires, HIV testing (HIV-negative partner), and HIV-1 viral load testing (HIV-positive partner). If a seroconversion occurred in the HIV-negative partner, anonymised phylogenetic analysis was done to compare HIV-1 pol and env sequences in both partners to identify linked transmissions. Couple-years of follow-up were eligible for inclusion if condomless sex was reported, use of pre-exposure prophylaxis or post-exposure prophylaxis was not reported by the HIV-negative partner, and the HIV-positive partner was virally suppressed (plasma HIV-1 RNA <200 copies per mL) at the most recent visit (within the past year). Incidence rate of HIV transmission was calculated as the number of phylogenetically linked HIV infections that occurred during eligible couple-years of follow-up divided by eligible couple-years of follow-up. Two-sided 95% CIs for the incidence rate of transmission were calculated using exact Poisson methods.

FINDINGS

Between Sept 15, 2010, and July 31, 2017, 972 gay couples were enrolled, of which 782 provided 1593 eligible couple-years of follow-up with a median follow-up of 2·0 years (IQR 1·1-3·5). At baseline, median age for HIV-positive partners was 40 years (IQR 33-46) and couples reported condomless sex for a median of 1·0 years (IQR 0·4-2·9). During eligible couple-years of follow-up, couples reported condomless anal sex a total of 76 088 times. 288 (37%) of 777 HIV-negative men reported condomless sex with other partners. 15 new HIV infections occurred during eligible couple-years of follow-up, but none were phylogenetically linked within-couple transmissions, resulting in an HIV transmission rate of zero (upper 95% CI 0·23 per 100 couple-years of follow-up).

INTERPRETATION

Our results provide a similar level of evidence on viral suppression and HIV transmission risk for gay men to that previously generated for heterosexual couples and suggest that the risk of HIV transmission in gay couples through condomless sex when HIV viral load is suppressed is effectively zero. Our findings support the message of the U=U (undetectable equals untransmittable) campaign, and the benefits of early testing and treatment for HIV.

A method for statistical analysis of repeated residential movements to link human mobility and HIV acquisition

We propose a method for analyzing repeated residential movements based on graphical loglinear models. This method allows an explicit representation of residential presence and absence patterns from several areas without defining mobility measures. We make use of our method to analyze data from one of the most comprehensive demographic surveillance sites in Africa that is characterized by high adult HIV prevalence, high levels of poverty and unemployment and frequent residential changes. Between 2004 and 2016, residential changes were recorded for 8,857 men over 35,500.01 person-years, and for 12,158 women over 57,945.35 person-years. These individuals were HIV negative at baseline. Over the study duration, there were a total of 806 HIV seroconversions in men, and 2,458 HIV seroconversions in women. Our method indicates that establishing a residence outside the rural study area is a strong predictor of HIV seroconversion in men (OR = 2.003, 95% CI = [1.718,2.332]), but not in women. Residing inside the rural study area in a single or in multiple locations is a less significant risk factor for HIV acquisition in both men and women compared to moving outside the rural study area.

Needs must: living donor liver transplantation from an HIV-positive mother to her HIV-negative child in Johannesburg, South Africa

The world's first living donor liver transplant from an HIV-positive mother to her HIV-negative child, performed by our team in Johannesburg, South Africa (SA) in 2017, was necessitated by disease profile and health system challenges. In our country, we have a major shortage of donor organs, which compels us to consider innovative solutions to save lives. Simultaneously, the transition of the HIV pandemic, from a death sentence to a chronic illness with excellent survival on treatment required us to rethink our policies regarding HIV infection and living donor liver transplantation . Although HIV infection in the donor is internationally considered an absolute contraindication for transplant to an HIV-negative recipient, there have been a very small number of unintentional transplants from HIV-positive deceased donors to HIV-negative recipients. These transplant recipients do well on antiretroviral medication and their graft survival is not compromised. We have had a number of HIV-positive parents in our setting express a desire to be living liver donors for their critically ill children. Declining these parents as living donors has become increasingly unjustifiable given the very small deceased donor pool in SA; and because many of these parents are virally suppressed and would otherwise fulfil our eligibility criteria as living donors. This paper discusses the evolution of HIV and transplantation in SA, highlights some of the primary ethical considerations for us when embarking on this case and considers the new ethical issues that have arisen since we undertook this transplant.

Acceptability of option B+ among HIV positive women receiving antenatal and postnatal care services in selected health centre's in Lusaka

BACKGROUND

In 2013, Zambia accepted the immediate operationalization of Option B+, a policy used to try and eliminate mother to child transmission. This policy requires all HIV-positive pregnant and breastfeeding women to initiate antiretroviral treatment for life regardless of CD4 count. However, not all HIV positive women accept treatment for life. This study aimed to investigate acceptability of lifelong ART (Option B+) among HIV positive women receiving antenatal and postnatal services at the university teaching hospital and Lusaka urban city clinics.

METHODS

This was a cross sectional study conducted in November, 2016 to March 2017. The study population comprised of HIV positive women in their reproductive age (15-49 years). A Structured questionnaire was used to collect data in a face to face interview with the participants. Data was entered in EpiData version 3.1 and analysed using Stata version 13. Multivariate logistic regression analysis was performed to determine predictors of acceptability.

RESULTS

Overall, 427 women participated in this study. Their mean age was 30 years. Of the 427, over half (54%) had inadequate knowledge and about 30% of the women in the study still experience stigma and discrimination.63.2% of the women had good attitude towards Option B+ and overall, the majority (77.8%) were willing to accept antiretroviral therapy for life. Multivariate analysis showed that only women with good attitude were 9.4 times more likely to accept Option B+ than those with a bad attitude [OR: 9.4: 95%CI, 5.8-15.2)].

CONCLUSION

This study showed that in general, women accepted initiation of Option B+. However, there is still a gap in the level of knowledge of Option B+ as well as stigma and discrimination in some communities, hence there is need to intensify programs that are aimed at educating the community on the importance of ART for life, combat stigma and discrimination and consequently promote acceptability of Option B+.

What Role Do Masculine Norms Play in Men's HIV Testing in Sub-Saharan Africa?: A Scoping Review

Men living with HIV/AIDS in sub-Saharan Africa are less likely to test for HIV than women. We conducted a scoping review in May of 2016 to identify how masculine norms influence men's HIV testing in sub-Saharan Africa. Our review yielded a total of 13 qualitative studies from 8 countries. Masculine norms create both barriers and facilitators to HIV testing. Barriers included emotional inexpression, gendered communication, social pressures to be strong and self-reliant, and the fear that an HIV positive result would threaten traditional social roles (i.e., husband, father, provider, worker) and reduce sexual success with women. Facilitators included perceptions that HIV testing could restore masculinity through regained physical strength and the ability to re-assume the provider role after accessing treatment. Across sub-Saharan Africa, masculinity appears to play an important role in men's decision to test for HIV and further research and interventions are needed to address this link.

Sexual and reproductive health behavior and unmet needs among a sample of adolescents living with HIV in Zambia: a cross-sectional study

BACKGROUND

Adolescents living with HIV face challenges, such as disclosure of HIV status, adherence to antiretroviral therapy, mental health, and sexual and reproductive health (SRH). These challenges affect their future quality of life. However, little evidence is available on their sexual behaviors and SRH needs in Zambia. This study aimed at assessing their sexual behaviors and SRH needs and identifying factors associated with marriage concerns and a desire to have children.

METHODS

This cross-sectional study was conducted at the University Teaching Hospital from April to July 2014. We recruited 200 adolescents aged 15-19 years who were aware of their HIV-positive status. We collected data on their first and recent sexual behavior, concerns about marriage, and desire to have children. We used the Generalized Linear Model to identify factors associated with having concerns about marriage and desire to have children. We performed thematic analysis with open-ended data to determine their perceptions about marriage and having children in the future.

RESULTS

Out of 175 studied adolescents, 20.6% had experienced sexual intercourse, and only 44.4% used condoms during the first intercourse. Forty-eight percent had concerns about marriage, and 87.4% desired to have children. Marriage-related concerns were high among those who desired to have children (adjusted relative risk [ARR] = 2.51, 95% CI = 1.02 to 6.14). Adolescents who had completed secondary school were more likely to desire to have children (ARR = 1.35, 95% CI = 1.07 to 1.71). Adolescents who had lost both parents were less likely to want children (ARR = 0.80, 95% CI = 0.68 to 0.95). Thematic analysis identified that major concerns about future marriage were fear of disclosing HIV status to partners and risk of infecting partners and/or children. The reasons for their willingness to have children were the desire to be a parent, having children as family assets, a human right, and a source of love and happiness.

CONCLUSIONS

Zambian adolescents living with HIV are at risk of engaging in risky sexual relationships and have difficulties in meeting needs of SRH. HIV care service must respond to a wide range of needs.

Pregnant and breastfeeding women: A priority population for HIV viral load monitoring

Landon Myer and colleagues discuss viral load monitoring for pregnant HIV-positive women and those breastfeeding; ART treatments can suppress viral load and are key to preventing transmission to the child.

Usefulness of nucleic acid testing to reduce risk of hepatitis B virus transfusion-transmitted infection in Argentina: high rate of recent infections

BACKGROUND

Results from 10-year experience using nucleic acid test (NAT) screening in a blood bank of Córdoba are presented, showing the first data on prevalence of recent hepatitis B virus (HBV) infections and occult HBV infections (OBIs) in Argentina.

STUDY DESIGN AND METHODS

Molecular screening was performed by COBAS AmpliScreen human immunodeficiency virus Type 1 (HIV-1) test Version 1.5 and COBAS AmpliScreen hepatitis C virus (HCV) test Version 2.0 and COBAS TaqScreen MPX and MPX Version 2.0 test (Roche Molecular Systems). To characterize OBI, additional molecular and serologic assays were performed.

RESULTS

As results of NAT, 0.075% of the donors (155/205,388) tested positive for HIV, 0.05% (106/205,388) for HCV, and 0.045% (76/168,215) for HBV. Donors who tested positive for HIV or HCV by NAT were also positive by serology. There was one of 33,643 donors recently infected with HBV. At time of donation, six of 76 (7.9%) donors with confirmed HBV infection presented virologic and serologic profiles consistent with OBI. By additional studies three were OBI, two were window period infections, and one remained unclassified.

CONCLUSION

NAT contributed significantly to the reduction of the potential risk of HBV transmission with a frequency of one in 56,072, detecting three in 168,215 donors without serologic evidence of infection. NAT also detected three in 168,215 OBIs. The finding of high frequency of recent infections (1/33,643), unexpected for this country, highlights the need of promoting unified effective regulations that enforce the use of NAT in all blood banks in Argentina and points out the importance of assessing the risk of HBV transmission in blood banks of other countries considered to be low-endemic.

[Meeting contraceptive needs of HIV-positive women: effect on elimination of vertical transmission of HIV]

Nearly 38% of unplanned pregnancies occur because of unmet contraceptive needs. In HIV-positive women, these figures triple, a phenomenon explained by social determinants such as poverty, access to health services, violence, and forced displacement, all of which are frequent elements in the lives of these women. Unplanned pregnancies represent a psychological burden related to women's fear of transmitting the infection to their children, orphanhood, and assuming risks during pregnancy, in addition to family and social consequences that are expressed in lack of prenatal care, neglect of their health, and an increased likelihood of vertical transmission. Technical assistance for differentiated contraception counseling integrated into HIV care and control services is basic to achieving short- and medium-term elimination of vertical transmission of HIV. These women's characteristics are different from those of the general population, as expressed in their reproductive lives, desires, and intentions regarding motherhood; and their unplanned pregnancies represent a greater psychological, social, and economic burden than that of other women. Recognizing this would allow contraception counseling to be provided by HIV care and follow-up programs, in the same place and time, with trained personnel, capable of understanding and meeting their reproductive needs within a rights-based framework, ensuring that health systems, based on the responsibility they have to society, would be capable of offering quality reproductive care counseling, aimed at meeting the specific needs of HIV-positive women.

``Eyes Wide Shut'' — Sexuality and risk in HIV-positive youth in Sweden: A qualitative study

Aims: This study explores the perception of sexual risk-taking behaviour in young HIV+ women and men in Sweden and their understanding of why they caught HIV. Method: In-depth interviews were conducted with 10 HIV+ women and men aged 17—24 years, 7 born in Sweden and 3 immigrants. Interviews were tape-recorded, transcribed verbatim, and analysed according to the stages of grounded theory. Results: The core category varying agency in the gendered sexual arena illustrated a spectrum of power available to these informants during sexual encounters. Two subcategories contextualized sexual practice: sociocultural blinds and from consensual to forced sex. Lack of adult supervision as a child, naïve views, being in love, alcohol and drugs, the macho ideal, and cultures of silence surrounding sexuality both individually and structurally all blinded them to the risks, making them vulnerable. Grouping narratives according to degree of consensus in sexual encounters demonstrated that sexual risks happened in a context of gendered power relations. Conclusion: This pioneering study reveals mechanisms that contribute to vulnerability and varied agency that may help in understanding why and how young people are at risk of contracting HIV. Public health strategies, which consider the role of gender and social background in the context of risky behaviours, could be developed from these findings.

HIV testing in the Danish population: A national representative survey, 2000

Aims: To describe the accumulated prevalence of HIV testing in the Danish population until and including the year 2000. Methods: The study was based on nationally representative data from the Danish Health Interview Survey 2000. Multiple logistic regression analysis investigated the association between HIV testing and background variables, such as gender, age, marital status, educational level, and sexual orientation. Results: Overall 28.5% of the Danish population aged over 16 years have ``ever been tested for HIV''. More females (29.4%) than males (27.6%) were tested; 12.6% might not be aware of their blood being HIV tested when donating blood. More males (17.1%) than females (13.8%) had donated blood after 1985. Although males 30—39 years old were the most tested, males 50—59 years old had the highest odds of having donated blood after 1985. Concerning education, the less education one had, the less likely one was to have been HIV tested. Of men having sex with men, only 44% were ``ever HIV tested''. Conclusions: Positive association between extent of HIV testing and some sociodemographic factors was seen. Heterosexuals are HIV tested at lower rates than men having sex with men. Yet, stronger promotion of HIV testing among men having sex with men is recommended. Targeting prevention efforts towards other known risk groups is also recommended.

Heterosexual Behavioral Maintenance and Change Following HIV Counseling and Testing

This study investigated heterosexual HIV risk behaviors, changes in stage of change for safer sex and factors associated with such changes, among a diverse sample of 560 heterosexually active individuals presenting at publicly funded HIV C&T sites. Questionnaires were administrated before HIV C&T, and three months afterwards. Positive serostatus was the most significant predictor of safer behavior after C&T. Many seronegative participants stopped sex with non-main partners. Behaviors with main partners were particularly resistant to change. Predictors of change varied by stage at pre-test. C&T services should tailor approaches and referrals based on stage of change and other client characteristics.

Cervical dyskaryosis among women with and without HIV: prevalence and risk factors

Women in developing countries often present for medical care with advanced cervical cancer, although this condition is preventable through regular screening and early treatment. This study sought to identify the prevalence and risk factors for cervical dyskaryosis among women in Zimbabwe with and without HIV.

In a cross-sectional study, 200 consenting women were screened for cervical dyskaryosis and sexually transmitted infections (STI). The relationship between various risk factors for cervical dyskaryosis was examined. The overall prevalence of cervical dyskaryosis was high (19%), and significantly higher among HIV-infected women at 30% compared with 13% among seronegative women, with a peak at a younger age among seropositive women. Use of intravaginal herbs, practising intravaginal cleansing, being single, a history of three or more lifetime sexual partners and a history of previous STI were associated with cervical dysplasia.

The high frequency of cervical abnormality lends weight to the demand for implementation of regular screening programmes and health education.

Prevalence of depressive symptoms in pregnant and postnatal HIV-positive women in Ukraine: a cross-sectional survey

BACKGROUND

Perinatal depression among HIV-positive women has negative implications for HIV-related and other maternal and infant outcomes. The aim of this study was to investigate the burden and correlates of perinatal depression among HIV-positive women in Ukraine, a lower middle income country with one of the largest HIV-positive populations in Europe.

METHODS

Cross-sectional surveys nested within the Ukraine European Collaborative Study were conducted of HIV-positive women at delivery and between 1 and 12 months postpartum. Depressive symptoms in the previous month were assessed using a self-report screening tool. Other data collected included demographics, antiretroviral therapy (ART)-related self-efficacy, and perceptions of risks/benefits of interventions to prevent mother-to-child transmission (PMTCT). Characteristics of women with and without a positive depression screening test result were compared using Fisher's exact test and χ2 test for categorical variables.

RESULTS

A quarter (27% (49/180) antenatally and 25% (57/228) postnatally) of participants screened positive for depressive symptoms. Antenatal risk factors were living alone (58% (7/12) vs. 25% (42/167) p = 0.02), being somewhat/terribly bothered by ART side effects (40% (17/43) vs. 23% (30/129) not /only slightly bothered, p = 0.05) and having lower ART-related self-efficacy (43% (12/28) vs. 23% (25/110) with higher self-efficacy, p = 0.05). Postnatally, single mothers were more likely to screen positive (44% (20/45) vs. 21% (18/84) of cohabiting and 19% (19/99) of married women, p < 0.01) as were those unsure of the effectiveness of neonatal prophylaxis (40% (20/45) vs. 18% (28/154) sure of effectiveness, p < 0.01), those worried that neonatal prophylaxis could harm the baby (30% (44/146) vs. 14% (10/73) not worried p < 0.01) and those not confident to ask for help with taking ART (48% (11/23) vs. 27% (10/37) fairly confident and 15 % (4/26) confident that they could do this). Of women who reported wanting help for their depressive symptoms, 82% (37/45) postnatally but only 31% (12/39) antenatally were already accessing peer counselling, treatment adherence programmes, support groups or social services.

CONCLUSIONS

A quarter of women screened positive for depression. Results highlight the need for proactive strategies to identify depressive symptoms, and an unmet need for provision of mental health support in the perinatal period for HIV-positive women in Ukraine.

Heterosexual Transmission of Subtype C HIV-1 Selects Consensus-Like Variants without Increased Replicative Capacity or Interferon-α Resistance

Heterosexual transmission of HIV-1 is characterized by a genetic bottleneck that selects a single viral variant, the transmitted/founder (TF), during most transmission events. To assess viral characteristics influencing HIV-1 transmission, we sequenced 167 near full-length viral genomes and generated 40 infectious molecular clones (IMC) including TF variants and multiple non-transmitted (NT) HIV-1 subtype C variants from six linked heterosexual transmission pairs near the time of transmission. Consensus-like genomes sensitive to donor antibodies were selected for during transmission in these six transmission pairs. However, TF variants did not demonstrate increased viral fitness in terms of particle infectivity or viral replicative capacity in activated peripheral blood mononuclear cells (PBMC) and monocyte-derived dendritic cells (MDDC). In addition, resistance of the TF variant to the antiviral effects of interferon-α (IFN-α) was not significantly different from that of non-transmitted variants from the same transmission pair. Thus neither in vitro viral replicative capacity nor IFN-α resistance discriminated the transmission potential of viruses in the quasispecies of these chronically infected individuals. However, our findings support the hypothesis that within-host evolution of HIV-1 in response to adaptive immune responses reduces viral transmission potential.

Despite the available HIV-1 diversity present in a chronically infected individual, single viral variants are transmitted in 80–90% of heterosexual transmission events. These breakthrough viruses may have unique properties that confer a higher capacity to transmit. Determining these properties could help inform the rational design of vaccines and enhance our understanding of viral transmission. We isolated the transmitted variant and a set of related non-transmitted variants from the transmitting partner near the estimated date of transmission from six epidemiologically linked transmission pairs to investigate viral correlates of transmission. The simplest explanation that transmitted variants are inherently more infectious or faster replicators in vitro did not hold true. In addition, transmitted variants did not replicate more efficiently than their non-transmitted counterparts in dendritic cells or in the presence of interferon-alpha in vitro, suggesting that they are not uniquely adapted to these components of the innate immune system. More ancestral genomes that were relatively sensitive to antibody neutralization tended to transmit, supporting previous reports that mutational escape away from the adaptive immune response likely reduces the ability to transmit. Our investigation into the traits of transmitted HIV-1 variants adds to the understanding of viral determinants of transmission.

Maternal transmission of HIV infection: a crime against my child?

This paper considers whether section 20 of the Offences Against the Person Act 1861, which has been used to prosecute those who transmit the HIV virus in sexual relationships (eg, R v Konzani), could be used to prosecute women (in England and Wales) who transmit the virus to their child during pregnancy, delivery or via breast feeding. The discussion concludes that prosecution for transmission in pregnancy/delivery is unlikely. However, it is argued that there might be scope to prosecute the transmission of the virus via breast feeding in the event that there was sufficient evidence. However, this would also be subject to the Crown Prosecution Service deeming such a prosecution to be in the public interest. The paper does not seek to examine the ethical issues involved. However, it acknowledges that this issue is part of a broader debate as to whether, and if so, when, it is appropriate to criminalise the transmission of disease.

High proportion of HIV serodiscordance among HIV-affected married couples in northern Vietnam

INTRODUCTION

Little is known about the state of HIV transmission among married couples in Vietnam. This study aims to clarify HIV serostatus in this group and elucidate risk factors for intra-marital HIV transmission.

METHODS

In 2012, we enrolled a group of HIV-positive married men registered at the HIV outpatient clinic of a referral hospital in northern Vietnam, along with their wives. Sociodemographic, behavioural and clinical data were collected from men and wives. HIV serodiscordant couples were followed until March 2014 to determine seroconversion rate. A phylogenetic analysis was performed based on env V3 sequence to detail cluster formation among men.

RESULTS

Of the 163 HIV-positive men enrolled in the study, 101 (62.0%) had wives testing HIV-negative. Half of men reported injecting drug use (IDU) as a likely transmission route. Couples reported a high incidence of unprotected sexual intercourse prior to diagnosis; the median (inter quartile range) was 4 (4-8) times per month. Only 17 couples (10.4%) reported using condoms during at least half these instances. Multivariable analysis revealed IDU history among men was independently associated with HIV-negative wives (adjusted OR 0.31; 95% CI 0.10-0.95, p=0.041). Phylogenetic analysis of 80 samples indicated CRF01_AE. Of these, 69 (86.3%) clustered with IDU-associated viruses from Vietnam. No HIV seroconversion was identified during a follow-up of 61 serodiscordant couples, with 126.5 person-years of observation during which HIV-infected men were on antiretroviral drug therapy (ART).

CONCLUSION

High HIV serodiscordance was observed among HIV-affected married couples in northern Vietnam. A large number of at-risk wives therefore remain HIV-negative and can be protected with measures including proper use of ART if couples are made aware of the serodiscordance through screening.

Loneliness, HIV-related stigma, and condom use among a predominantly rural sample of HIV-positive men who have sex with men (MSM)

Most previous studies of the sexual behaviors of men who have sex with men (MSM) living with HIV are based on samples recruited within relatively urban and suburban areas of the United States. Using an internet-based questionnaire, we assessed HIV-related stigma, loneliness, and event-level sexual behaviors in a sample of HIV positive MSM (n = 100) residing within a largely rural area in the Midwestern United States. HIV-related stigma was correlated with loneliness (r = 0.619, p < 0.01). Loneliness was negatively associated with condom usage with the most recent partner of unknown status (p < 0.05). Namely, a 1-unit increase in the UCLA loneliness score was met with a 10% decrease in odds of condom usage. Further studies are warranted that explore loneliness, within the context of HIV-related stigma, among HIV-positive MSM residing in rural areas. More refined data will inform clinical and social service practice, as they provide much-needed information on sexual health outcomes and experiences of an often underserved and under studied population.

The efficacy of serostatus disclosure for HIV Transmission risk reduction

Interventions to assist HIV+ persons in disclosing their serostatus to sexual partners can play an important role in curbing rates of HIV transmission among men who have sex with men (MSM). Based on the methods of Pinkerton and Galletly (AIDS Behav 11:698-705, 2007), we develop a mathematical probability model for evaluating effectiveness of serostatus disclosure in reducing the risk of HIV transmission and extend the model to examine the impact of serosorting. In baseline data from 164 HIV+ MSM participating in a randomized controlled trial of a disclosure intervention, disclosure is associated with a 45.0 % reduction in the risk of HIV transmission. Accounting for serosorting, a 61.2 % reduction in risk due to disclosure was observed in serodisconcordant couples. The reduction in risk for seroconcordant couples was 38.4 %. Evidence provided supports the value of serostatus disclosure as a risk reduction strategy in HIV+ MSM. Interventions to increase serostatus disclosure and that address serosorting behaviors are needed.

Impulsivity as a risk factor for HIV transmission in men who have sex with men: a delay discounting approach

Delay discounting (DD) is a measure of impulsivity that describes the subjective decline in value of a consequence as the delay to that consequence increases. We sought to assess whether the results of a monetary DD task would be predictive of sexual risk-taking in a group of Internet-using men who have sex with men (MSM). 1402 participants completed an online survey that included questions about the participant's demographics, sexual history and behavior, drug use, sexual compulsivity, and a monetary DD task. High DD was associated with increased odds of reporting >2 UAI partners in the past 12 months [aOR = 1.5 (1.1-2.1)]. Future studies should examine the utility of DD as a predictor of risky sexual behavior, as well as explore the possibility of HIV prevention interventions targeting DD.

Opportunities for improving partner notification for HIV: results from a community-based participatory research study

To identify actionable opportunities for improving Partner Notification (PN) for HIV among men who have sex with men (MSM), we characterized the perspectives and experiences of PN among Medical Case Managers (case managers), Disease Intervention Specialists (DIS), and MSM. In partnership with an AIDS service organization and the Connecticut State Health Department, we conducted a focus group of case managers (n = 14) and in-depth interviews with DIS (n = 7) and MSM (n = 24). We found differences between MSM's and providers' (case managers and DIS) perspectives regarding (1) determinants of sexual risk behaviors; (2) considerations impacting HIV disclosure; and (3) barriers to trusting relationships between MSM and providers. Factors impacting MSM perspectives on PN were incompletely appreciated by both case managers and DIS. PN may be improved through improving provider understanding of the complexities for MSM regarding sexual risk behaviors and disclosure and transcending barriers to trusting relationships between MSM and providers.

Fertility desires and intentions among HIV-positive women during the post-natal period in Uganda

This study describes the fertility intentions and discusses the potential reproductive health needs of post-natal HIV-infected Ugandan women. HIV-infected mothers attending post-natal services in Kampala, Uganda participated in this cross-sectional study using structured interviewer administered questionnaires. Descriptive statistics and logistic regression models were used to identify predictors of desire for more children. Among 403 participants, 35% desired more children. Of these, 25% wanted another child within 2 years and 75% within 3 years or more. In multivariable analyses, believing that one's partners wanted more children (OR = 2.44; 95% CI = 1.30, 4.59) was associated with the desire for future children while having more living children was negatively associated with the desire for future children (OR = 0.08; 95% CI = 0.02, 0.39). A minority of women desired future pregnancies, and most wanted to delay pregnancy for 3 years. These women are in need of family planning (FP) methods to meet stated desires to delay or end future pregnancies. Perceived partner desire for children also impacts on women's fertility intentions, highlighting the importance of engaging men during the post-natal period.67-77)

Oral pre-exposure prophylaxis (PrEP) for prevention of HIV in serodiscordant heterosexual couples in the United States: opportunities and challenges

Oral HIV pre-exposure prophylaxis (PrEP) is a promising new biomedical prevention approach in which HIV-negative individuals are provided with daily oral antiretroviral medication for the primary prevention of HIV-1. Several clinical trials have demonstrated efficacy of oral PrEP for HIV prevention among groups at high risk for HIV, with adherence closely associated with level of risk reduction. In the United States (US), three groups have been prioritized for initial implementation of PrEP-injection drug users, men who have sex with men at substantial risk for HIV, and HIV-negative partners within serodiscordant heterosexual couples. Numerous demonstration projects involving PrEP implementation among MSM are underway, but relatively little research has been devoted to study PrEP implementation in HIV-serodiscordant heterosexual couples in the US. Such couples face a unique set of challenges to PrEP implementation at the individual, couple, and provider level with regard to PrEP uptake and maintenance, adherence, safety and toxicity, clinical monitoring, and sexual risk behavior. Oral PrEP also provides new opportunities for serodiscordant couples and healthcare providers for primary prevention and reproductive health. This article provides a review of the critical issues, challenges, and opportunities involved in the implementation of oral PrEP among HIV-serodiscordant heterosexual couples in the US.

Types of female partners reported by black men who have sex with men and women (MSMW) and associations with intercourse frequency, unprotected sex and HIV and STI prevalence

We used baseline data from a study of Black MSM/MSMW in 6 US cities to examine the association of female partnership types with disease prevalence and sexual behaviors among the 555 MSMW participants. MSMW reported more than three times as many total and unprotected sex acts with each primary as they did with each non-primary female partner. We compared MSMW whose recent female partners were: (1) all primary ("PF only", n = 156), (2) both primary and non-primary ("PF & NPF", n = 186), and (3) all non-primary ("NPF only", n = 213). HIV/STI prevalence did not differ significantly across groups but sexual behaviors did. The PF only group had the fewest male partners and was the most likely to have only primary male partners; the PF & NPF group was the most likely to have transgender partners. PF & NPF men reported the most sex acts (total and unprotected) with females; NPF only men reported the fewest. Implications for HIV risk and prevention are discussed.

Interdisciplinary correlations regarding the clinical and paraclinical evaluations in HIV-positive pregnant women

HIV infection in pregnancy has an increasing prevalence due to the effectiveness of antiretroviral therapy. The risk of HIV vertical transmission varies between 15-20 % in European women who do not breastfeed and 25-40% in African mothers who breastfeed. The most important predictive factor of the vertical transmission is maternal plasma HIV viral load. Vertical transmission can be largely prevented by prenatal screening, perigestational ART, an adapted obstetrical attitude and exclusively artificial feeding of the infant.

MATERIAL AND METHOD

The study included 36 HIV-positive pregnant women, between 2012-2014, at age of 25-32 years.

RESULTS AND DISCUSSIONS

It has been found that the birth weight was less than 2,700 grams in all newborns of HIV-positive pregnant women or those with advanced disease (AIDS) and, also, they received an APGAR score less than 7. The primordial desideratum is to decrease the rate of mother-fetus vertical transmission, thus the caesarian section has been established as the birth method in all HIV-positive pregnant women after 38 weeks of amenorrhea, on intact membranes, outside labor, resulting in halving the percentage of HIV-positive children. A very important role belongs to the interdisciplinary collaboration between the obstetrician and the infectious diseases specialist during the pregnancy, but also during the postpartum period. The role of the obstetrician is present in all the moments of pregnancy evolution. The HIV-positive pregnant woman is included in the group of high risk pregnancies.

Factors associated with disclosure of HIV status among a cohort of individuals on antiretroviral therapy in British Columbia, Canada

We sought to examine the prevalence and correlates of HIV-disclosure among treatment-experienced individuals in British Columbia, Canada. Study participants completed an interviewer-administered survey between July 2007 and January 2010. The primary outcome of interest was disclosing one's HIV-positive status to all new sexual partners within the last 6 months. An exploratory logistic regression model was developed to identify variables independently associated with disclosure. Of the 657 participants included in this analysis, 73.4 % disclosed their HIV-positive status to all of their sexual partners. Factors independently associated with non-disclosure included identifying as a woman (adjusted odds ratio [AOR] 1.92; 95 % confidence interval [95 % CI] 1.13-3.27) or as a gay or bisexual man (AOR 2.45; 95 % CI 1.47-4.10). Behaviours that were independently associated with non-disclosure were having sex with a stranger (AOR 2.74; 95 % CI 1.46-5.17), not being on treatment at the time of interview (AOR 2.67; 95 % CI 1.40-5.11), and not always using a condom (AOR 1.78; 95 % CI 1.09-2.90). Future preventative strategies should focus on environmental and social factors that may inhibit vulnerable HIV-positive populations, such as women and gay or bisexual men, from safely disclosing their positive status.

Beyond prevention: containment rhetoric in the case of bug chasing

Bug chasing, the practice of pursuing HIV positive sexual partners in order to acquire HIV, presents multiple dilemmas for health affiliates in terms of how to address discourses and practices that challenge widely held beliefs about health and medicine. In order to examine how researchers respond to controversial counterpublic rhetorics, this essay chronicles the construction of "bug chasing" in published social science literature. Guided by a theory of containment rhetoric, I analyze how bug chasers are configured in the language of social science used to describe and explain them. I find that social scientific coverage of bug chasing often addresses the behavior using a recipe of rhetorical containment: first, authors gaze upon bug chasers via distanced descriptions of the community; second, authors characterize the behavior as exhibiting an idealistic naiveté; and, third, authors stress the inconceivable, and therefore reproachable, sacrifice that bug chasing ultimately demands of its onlookers and participants. In closing, I evaluate the consequences of this containment rhetoric and offer three rhetorical maneuvers to aid future scholarship that examines the discourses and communities that counter dominant health ideologies.

The role of viral introductions in sustaining community-based HIV epidemics in rural Uganda: evidence from spatial clustering, phylogenetics, and egocentric transmission models

BACKGROUND

It is often assumed that local sexual networks play a dominant role in HIV spread in sub-Saharan Africa. The aim of this study was to determine the extent to which continued HIV transmission in rural communities--home to two-thirds of the African population--is driven by intra-community sexual networks versus viral introductions from outside of communities.

METHODS AND FINDINGS

We analyzed the spatial dynamics of HIV transmission in rural Rakai District, Uganda, using data from a cohort of 14,594 individuals within 46 communities. We applied spatial clustering statistics, viral phylogenetics, and probabilistic transmission models to quantify the relative contribution of viral introductions into communities versus community- and household-based transmission to HIV incidence. Individuals living in households with HIV-incident (n = 189) or HIV-prevalent (n = 1,597) persons were 3.2 (95% CI: 2.7-3.7) times more likely to be HIV infected themselves compared to the population in general, but spatial clustering outside of households was relatively weak and was confined to distances <500 m. Phylogenetic analyses of gag and env genes suggest that chains of transmission frequently cross community boundaries. A total of 95 phylogenetic clusters were identified, of which 44% (42/95) were two individuals sharing a household. Among the remaining clusters, 72% (38/53) crossed community boundaries. Using the locations of self-reported sexual partners, we estimate that 39% (95% CI: 34%-42%) of new viral transmissions occur within stable household partnerships, and that among those infected by extra-household sexual partners, 62% (95% CI: 55%-70%) are infected by sexual partners from outside their community. These results rely on the representativeness of the sample and the quality of self-reported partnership data and may not reflect HIV transmission patterns outside of Rakai.

CONCLUSIONS

Our findings suggest that HIV introductions into communities are common and account for a significant proportion of new HIV infections acquired outside of households in rural Uganda, though the extent to which this is true elsewhere in Africa remains unknown. Our results also suggest that HIV prevention efforts should be implemented at spatial scales broader than the community and should target key populations likely responsible for introductions into communities.

Commonalities and differences in infant feeding attitudes and practices in the context of HIV in sub-Saharan Africa: a metasynthesis

Exclusive breastfeeding (EBF) has been identified as a key intervention to promote infant health and to reduce the vertical transmission of HIV. Despite this knowledge and increased resources to promote EBF, the practice in sub-Saharan Africa (SSA) remains low among HIV+ women. Although a number of qualitative studies have been conducted throughout SSA, the influences on and consequences of infant feeding choices of HIV+ mothers' findings have not been regarded systematically. Therefore, our objective was to identify overarching themes, commonalities, and differences in infant feeding choices among qualitative studies with HIV+ mothers in SSA. Sixteen qualitative studies of infant feeding practices in the context of HIV were identified. Noblit and Hare's seven-step metasynthesis methodology was used to analyze the experiences of HIV+ women and those who provide infant feeding services/counseling. Data were available from approximately 920 participants (i.e., 750 HIV+ mothers, 109 health-care providers, and 62 family members) across 13 SSA countries from 2000 to 2011. From these data, five themes emerged within which 3-4 overarching key metaphors were identified. The consistency of key metaphors across a variety of geographic, economic, and cultural settings suggest the importance of approaching infant feeding holistically, within the context of maternal knowledge, health-care support, family resources, and cultural expectations. EBF campaigns in SSA are more likely to successfully support optimal health for infants and a safe supportive environment for their mothers when the impact of infant feeding decisions are evaluated across these themes.

Reducing HIV and AIDS in adolescents: opportunities and challenges

Adolescents are critical to efforts to end the AIDS epidemic. Few national AIDS strategies explicitly program for children in their second decade of life. Adolescents (aged 10-19 years) are therefore largely invisible in global, regional, and country HIV and AIDS reports making it difficult to assess progress in this population. We have unprecedented knowledge to guide investment towards greater impact on HIV prevention, treatment, and care in adolescents, but it has not been applied to reach those most vulnerable and optimize efficiency and scale. The cost of this is increasing AIDS-related deaths and largely unchanged levels of new HIV infections in adolescents. An AIDS-free generation will remain out of reach if the global community does not prioritize adolescents. National AIDS responses must be accountable to adolescents, invest in strengthening and monitoring protective and supportive laws and policies and access for adolescents to high impact HIV interventions.

Antiretroviral therapy reduces HIV transmission in discordant couples in rural Yunnan, China

Background

Although HIV treatment as prevention (TasP) via early antiretroviral therapy (ART) has proven to reduce transmissions among HIV-serodiscordant couples, its full implementation in developing countries remains a challenge. In this study, we determine whether China's current HIV treatment program prevents new HIV infections among discordant couples in rural China.

Methods

A prospective, longitudinal cohort study was conducted from June 2009 to March 2011, in rural Yunnan. A total of 1,618 HIV-discordant couples were eligible, 1,101 were enrolled, and 813 were followed for an average of 1.4 person-years (PY). Routine ART was prescribed to HIV-positive spouses according to eligibility (CD4<350 cells/µl). Seroconversion was used to determine HIV incidence.

Results

A total of 17 seroconversions were documented within 1,127 PY of follow-up, for an overall incidence of 1.5 per 100 PY. Epidemiological and genetic evidence confirmed that all 17 seroconverters were infected via marital secondary sexual transmission. Having an ART-experienced HIV-positive partner was associated with a lower rate of seroconvertion compared with having an ART-naïve HIV-positive partner (0.8 per 100 PY vs. 2.4 per 100 PY, HR = 0.34, 95%CI = 0.12–0.97, p = 0.0436). While we found that ART successfully suppressed plasma viral load to <400 copies/ml in the majority of cases (85.0% vs. 19.5%, p<0.0001 at baseline), we did document five seroconversions among ART-experienced subgroup.

Conclusions

ART is associated with a 66% reduction in HIV incidence among discordant couples in our sample, demonstrating the effectiveness of China's HIV treatment program at preventing new infections, and providing support for earlier ART initiation and TasP implementation in this region.

Developing an online health intervention for young gay and bisexual men

Young gay and bisexual men continue to experience increases in HIV incidence in the US highlighting a need for competent health services, while the prominence of the internet in their social and sexual lives calls for novel preventive modalities. Toward this goal, we adapted an efficacious in-office HIV risk reduction intervention for online delivery. This paper describes the development of the online intervention and highlights the results of interviews and focus groups with the original intervention participants regarding effective adaptation and online delivery recommendations. The final intervention incorporates strategies for overcoming barriers to online intervention with this population and capitalizes on the unique strengths of online intervention delivery. The systematic process described in this paper can be used as a template for other researchers to develop online risk reduction programs and fills an important gap in the field's ability to maximally reach a critical risk group.

Gender disparities in HIV infection among persons who inject drugs in Central Asia: a systematic review and meta-analysis

OBJECTIVE

Disparities in HIV infection, with females having higher rates of HIV infection than males, have been noted among persons who inject drugs (PWID) in many countries. We examined male/female HIV disparities among PWID in Central Asia and compared these disparities with patterns worldwide.

METHODS

A systematic review and meta-analyses were conducted for studies reporting HIV prevalence by gender among PWID. To be included in the analyses, reports had to contain (1) samples of PWID from Central Asia, (2) HIV data based on laboratory testing, (3) HIV prevalence reported for males and females, and (4) samples that were not recruited on the basis of HIV status.

RESULTS

Data were abstracted from 11 studies in 5 countries in Central Asia: China, Kazakhstan, Russia, Tajikistan, and Uzbekistan; the total sample size was 12,225. The mean weighted OR for HIV prevalence among females to males was 0.913 (95% CI 0.07, 1.26), with high heterogeneity among studies (I(2)=70.0%) and a possible publication bias among studies with small sample sizes (Eggers test=-1.81, 95% CI -5.18, 0.54).

CONCLUSIONS

The non-significant higher HIV prevalence among male PWID in Central Asia contrasts with the worldwide findings which show slightly higher HIV prevalence among female PWID. This may reflect the relative recency of the HIV epidemics in Central Asia. The findings also suggest there may be factors that protect female PWID from HIV in some settings. Further examination of transmission dynamics in Central Asia is necessary to better understand the HIV epidemic among PWID.

Maternal HIV serostatus, mother-daughter sexual risk communication and adolescent HIV risk beliefs and intentions

Daughters of HIV-positive women are often exposed to the same factors that placed their mothers at risk. This cross-sectional study (N = 176 dyads) examined HIV status, parent-teen sexual risk communication (PTSRC), and daughters' abstinence and condom use beliefs and intentions. Maternal HIV status was not associated with PTSRC. Path analyses show that maternal depression was associated with PTSRC behavioral and normative beliefs; relationship satisfaction was associated with PTSRC normative and control beliefs. Control beliefs were solely predictive of maternal PTSRC intention. PTSRC was associated with adolescent behavioral and normative beliefs. Abstinence beliefs were associated with abstinence intentions; condom beliefs were associated with condom use intentions. Relationship satisfaction was associated with adolescent control beliefs about both abstinence and condom use. There is a need for interventions that help HIV-positive mothers recognize their daughter's HIV risk and provide them with relationship building and parent process skills to help reduce these risks.

Structural barriers to receiving health care services for female sex workers in Russia

Female sex workers in Russia have been particularly vulnerable to recent social, political, and economic changes. In this article, we describe the facilitators and barriers for sex workers receiving health care services in St. Petersburg, Russia. We conducted observations at medical institutions and nongovernmental organizations and in-depth interviews with 29 female sex workers. We identified the following barriers: poverty, not having documents, lack of anonymity in testing, and the official registration system. We identified the following facilitators: intervention by family members, social connections within the health care system, and referral services from a nongovernmental organization. Our findings indicate a need for reassessing policies and designing programs that better facilitate the use of health care services for the most vulnerable populations. This should include the expansion of support systems and outreach services designed to help female sex workers navigate the health care system.
