No association between HIV status and risk of non-fatal overdose among people who inject drugs in Vancouver, Canada

BACKGROUND:
The evidence to date on whether HIV infection increases the risk of accidental drug overdose among people who inject drugs (PWID) is equivocal. Thus, we sought to estimate the effect of HIV infection on risk of non-fatal overdose among two parallel cohorts of HIV-positive and -negative PWID.

METHODS:
Data were collected from a prospective cohort of PWID in Vancouver, Canada between 2006 and 2013. During biannual follow-up assessments, non-fatal overdose within the previous 6months was assessed. Bivariable and multivariable generalized mixed-effects regression models were used to determine the unadjusted and adjusted associations between HIV status, plasma HIV-1 RNA viral load, and likelihood of non-fatal overdose.

RESULTS:
A total of 1760 eligible participants (67% male, median age=42, and 42% HIV-positive at baseline) were included. Among 15,070 unique observations, 649 (4.3%) included a report of a non-fatal overdose within the previous 6months (4.4% among seropositive and 4.3% among seronegative individuals). We did not observe a difference in the likelihood of overdose by HIV serostatus in crude (odds ratio [OR]: 1.05, p=0.853) analyses or analyses adjusted for known overdose risk factors (adjusted OR [AOR]: 1.19, p=0.474). In a secondary analysis, among HIV-positive PWID, we did not observe an association between having a detectable viral load and overdose (AOR: 1.03, p=0.862).

CONCLUSIONS:
Despite the evidence that HIV infection is a risk factor for fatal overdose, we found no evidence for a relationship between HIV disease and non-fatal overdose. However, overdose remains high among PWID, indicating the need for ongoing policy addressing this problem, and research into understanding modifiable risk factors that predict non-fatal overdose.

Socioeconomic Disconnection as a Risk Factor for Increased HIV Infection in Young Men Who Have Sex with Men

PURPOSE:
HIV disproportionately affects young men who have sex with men (YMSM), particularly black YMSM. Increasingly, researchers are turning to social, economic, and structural factors to explain these disproportionate rates. In this study, we explore the relationship between socioeconomic disconnection and HIV status and factors related to HIV infection, including drug use, condomless anal sex, and binge drinking. We operationalize socioeconomic disconnection in this young population as lack of engagement in educational and employment opportunities.

METHODS:
Baseline data were analyzed from a longitudinal cohort study of YMSM aged 16-20 years recruited from the Chicago area (N = 450). Bivariate analyses of the association of socioeconomic disconnection and HIV-positive status, drug and alcohol use, and condomless anal sex were assessed using chi-square tests. The relationship of socioeconomic disconnection and HIV-positive status was then examined in multivariate logistic regression models, controlling for age and race/ethnicity and significant behavioral factors.

RESULTS:
Among study participants, 112 (25%) were not in school, 310 (69%) were not currently working, and 81 (18%) were neither in school nor working. Black MSM were more likely to be socioeconomically disconnected (neither in school nor working; n = 56, 23.3%). The results revealed that disconnected YMSM were more likely to binge drink (AOR = 2.34; 95% CI = 1.16, 4.74) and be HIV positive (AOR = 2.24; 95% CI = 1.04, 4.83). Subpopulation analysis for black participants revealed similar associations (AOR of binge drinking = 2.92; 95% CI = 1.07, 8.01; AOR of HIV positive = 2.38; 95% CI = 1.03, 5.51). Controlling for substance use, the association between disconnection and HIV-positive status remained significant (AOR = 2.37; 95% CI = 1.08, 5.20).

CONCLUSION:
Socioeconomic disconnection is significantly and positively associated with HIV status among YMSM, suggesting that the two factors are related. Socioeconomic factors present an important area for future research focusing on HIV infection in this high-risk group.

‘I am doing fine only because I have not told anyone’: The necessity of concealment in the lives of people living with HIV in India

In HIV prevention and care programmes, disclosure of status by HIV-positive individuals is generally encouraged to contain the infection and provide adequate support to the person concerned. Lack of disclosure is generally framed as a barrier to preventive behaviours and accessing support. The assumption that disclosure is beneficial is also reflected in studies that aim to identify determinants of disclosure and recommend individual-level measures to promote disclosure. However, in contexts where HIV infection is stigmatised and there is fear of rejection and discrimination among those living with HIV, concealment of status becomes a way to try and regain as much as possible the life that was disrupted by the discovery of HIV infection. In this study of HIV-positive women and children in India, concealment was considered essential by individuals and families of those living with HIV to re-establish and maintain their normal lives in an environment where stigma and discrimination were prevalent. This paper describes why women and care givers of children felt the need to conceal HIV status, the various ways in which people tried to do so and the implications for treatment of people living with HIV. We found that while women were generally willing to disclose their status to their husband or partner, they were very keen to conceal their status from all others, including family members. Parents and carers with an HIV-positive child were not willing to disclose this status to the child or to others. Understanding the different rationales for concealment would help policy makers and programme managers to develop more appropriate care management strategies and train care providers to assist clients in accessing care and support without disrupting their lives.

...[E]very participant was extremely concerned about concealment and described various means they employed in order to achieve this. These included hiding their ART registers, decanting their medication and leaving the pill boxes at the clinic, using a generic container to store the pills and coming up with alternate explanations for visits to the clinic and taking medication:

I keep the card in a cover and then keep it inside a cupboard below the sarees. Once a month when I come here, I take it from the cupboard and bring it here.

(Widow living with HIV, W1)

I bring one box from my home, transfer the tablets to it and leave this box here only.

(Widow living with HIV, W6)

There used to be an LIC (insurance) office just opposite this hospital so whenever I come here, I tell people who ask me where I am going that I am going to pay the premium. Luckily no one knows that the office has been shifted from here.

(Caregiver of HIV-positive child, PO9)

They ask me why I am taking these tablets. I tell them that I am taking this for fever.

Number of Drinks to "Feel a Buzz" by HIV Status and Viral Load in Men

The impact of HIV and its treatment on the effects of alcohol remain unclear. Blood alcohol concentrations have been noted to be higher in HIV infected individuals prior to antiretroviral initiation. 

Our goal was to compare number of drinks to "feel a buzz or high" among HIV infected and uninfected men, stratified by viral load (VL) suppression. Data includes 1478 HIV infected and 1170 uninfected men in the veterans aging cohort study who endorsed current drinking. 

Mean (SD) number of drinks to feel a buzz was 3.1 (1.7) overall. In multivariable analyses, HIV infected men reported a lower mean number of drinks to feel a buzz compared to uninfected men (coef = -14 for VL < 500; -34 for VL ≥ 500; p ≤ .05). Men with HIV, especially those with a detectable VL, reported fewer drinks to feel a buzz. 

Future research on the relationship between alcohol and HIV should consider the role of VL suppression.

Beyond Condoms: Risk Reduction Strategies among Gay, Bisexual & Other Men Who Have Sex with Men Receiving Rapid HIV Testing in Montreal, Canada

Gay, bisexual, and other men who have sex with men (MSM) have adapted their sexual practices over the course of the HIV/AIDS epidemic based on available data and knowledge about HIV. This study sought to identify and compare patterns in condom use among gay, bisexual, and other MSM who were tested for HIV at a community-based testing site in Montreal, Canada. 

Results showed that while study participants use condoms to a certain extent with HIV-positive partners and partners of unknown HIV status, they also make use of various other strategies such as adjusting to a partner's presumed or known HIV status and viral load, avoiding certain types of partners, taking PEP, and getting tested for HIV. 

These findings suggest that MSM who use condoms less systematically are not necessarily taking fewer precautions but may instead be combining or replacing condom use with other approaches to risk reduction.

Caregivers’ Attitudes towards HIV Testing and Disclosure of HIV Status to At-Risk Children in Rural Uganda

Caregivers of HIV-positive children were interviewed in the Mbarara and Isingiro districts of Uganda to identify current trends in practices related to HIV testing and the disclosure of HIV status to the child. 

A total of 28 caregivers of at least one HIV-positive child participated in semi-structured interviews exploring when and why they tested the child for HIV, when the child was informed of their positive status, and what the caregiver did to prepare themselves and the child for status disclosure. 

For a majority (96%) of respondents, the decision to test the child for HIV was due to existing illness in either the child or a relative. Other common themes identified included the existence of stigma in the caregivers’ communities and doubt that the children truly understood what was being explained to them when their status was disclosed. Most (65%) children were informed of their HIV status between the ages of 5 and 9, with the mean age of disclosure occurring at the age of 7. General provision of HIV information typically began at the same age as disclosure, and as many as two thirds (64%) of the caregivers sought advice from an HIV counsellor prior to disclosure. How a caregiver chose to prepare themselves and the child did not affect the caregiver’s perception of whether the disclosure experience was beneficial or not. 

These findings suggest that the HIV disclosure experience in Mbarara and Isingiro districts differs from current guidelines, especially with respect to age of disclosure, how caregivers prepare themselves and the child, and approaching disclosure as an ongoing process. The doubts expressed by caregivers regarding the child’s level of HIV understanding following the disclosure experience suggest the children may be insufficiently prepared at the time of the initial disclosure event. 

The findings also suggest that examining the content of pre-disclosure counselling and HIV education, and how health care professionals are trained to facilitate the disclosure process as important avenues for further research.

Effect of Nondisclosure of HIV Status in Sexual Health Clinics on Unlinked Anonymous HIV Prevalence Estimates in England, 2005–2009

Objectives: To assess the extent of nondisclosure of known HIV status among sexual health clinic attendees and to quantify the impact of nondisclosure on estimates of undiagnosed HIV prevalence and of the proportion of patients remaining undiagnosed on leaving the clinic.

Methods: Serum samples from the unlinked anonymous survey of clinic attendees’ archive were tested for antiretrovirals. Estimates of undiagnosed HIV were adjusted using the findings.

Results: Antiretrovirals were detected in 27% of samples taken from ‘previously undiagnosed’ attendees, who did not have an HIV test but were HIV positive as detected by unlinked anonymous testing, indicating nondisclosure; 24% of such samples from MSM had antiretrovirals present compared with 32% of heterosexual men and women. Antiretrovirals were detected in 33% of samples from London clinics and in 21% from non-London clinics. Following adjustment, the estimated prevalence of undiagnosed HIV decreased nonsignificantly from 3.04% to 2.66% (2.35–3.01) among men who have sex with men (MSM), 0.31% (0.26–0.37) to 0.30% (0.25–0.36) in heterosexual men and 0.40% (0.35–0.46) to 0.37% (0.32–0.43) in women; 7% of MSM who do not have an HIV test at a clinic visit will be infected with HIV and remain unaware of their infection.

Conclusion: Nondisclosure of HIV status to healthcare professionals occurs among clinic attendees. Adjustment for nondisclosure results in a small, nonsignificant decrease in the prevalence of undiagnosed HIV estimated from the unlinked anonymous survey in sexual health clinics. Testing the population of MSM not having an HIV test remains a priority as levels of undiagnosed HIV are high.

Female Sexual Partners of Male People Who Inject Drugs in Vietnam Have Poor Knowledge of Their Male Partners' HIV Status

Vietnam's HIV epidemic is concentrated among male people who inject drugs (PWID), and their female sexual partners (SPs) may be at risk for infection. HIV prevention interventions for SPs were implemented in Hanoi, Dien Bien Province, and Ho Chi Minh City (HCMC), and data from linked surveys used to evaluate these interventions offered an unusual opportunity to assess knowledge of HIV status within couples.

Linked surveys (behavioral interviews and HIV testing) among 200 PWID-SP couples in Hanoi, 300 in Dien Bien, and 249 in HCMC.

HIV prevalence among male PWID was 
  • 53% in Hanoi, 
  • 30% in Dien Bien, and 
  • 46% in HCMC, 
  • and lower among their SPs: 44%, 10%, and 37%, respectively. 

Comparison of SPs' beliefs regarding male PWID partners' HIV status with the PWIDs' actual test results revealed that 32% of SPs in Dien Bien and 44% in Hanoi and HCMC lacked correct knowledge of their male partners' status. This proportion was slightly lower (21%-33%) among SPs whose PWID partners reported having been previously tested and received HIV+ results.

SP interventions reached HIV-negative women in serodiscordant relationships, and some improvements occurred in condom use and relationship characteristics. Nevertheless, our findings suggest that at least 11,000 SPs in Vietnam may be at high risk for HIV infection because of incorrect knowledge of their partners' HIV status. Interventions should be strengthened in HIV testing, disclosure, and treatment, as well as empowerment of SPs as individuals, within couples, and as communities.

Impact of Incarceration Experiences on Reported HIV Status & Associated Risk Behaviours & Disease Comorbidities

The Russian human immunodeficiency virus (HIV) epidemic among people who inject drugs (PWID) originated in Kaliningrad, but research into risk behaviours among PWID has been lacking. The potential for heterosexual spread has not been analysed.

A sample of PWID was accrued using two methods. A questionnaire was administered to assess HIV-related risk behaviours for parenteral and sexual transmission, sociodemographic factors, HIV knowledge and attitudes about sexual risks. Data were analysed focusing on the role of imprisonment, factors associated with awareness of being HIV infected and condom use.
  • More than a quarter of the sample reported having been diagnosed with HIV infection, with higher prevalence among women and those with a history of incarceration. 
  • More than half reported having been diagnosed with hepatitis C virus infection. 
  • Those reporting being HIV positive were less likely to distribute used syringes to other PWID 
  • and more likely to have used a condom the last time they had sex. 
  • A history of incarceration was associated with higher rates of receptive syringe sharing among those not having ever received an HIV-positive diagnosis 
  • and a lower likelihood of believing that condoms are needed when having sex with a casual partner.

Although extensive HIV testing has alerted many PWID to their HIV-positive status, which is associated with less distributive syringe sharing and higher likelihood of condom use, substantial risk for parenteral and especially sexual HIV transmission remains. 

More active prevention programs will be required to control the heterosexual spread of HIV.

Effect of Couples Counselling on Reported HIV Risk Behaviour among HIV Serodiscordant Couples by ART Use, HIV Status and Gender in Rural Uganda

We examined several measures of self-reported HIV risk behaviour in mutually disclosed sero-discordant couples over time to see if a couples counselling intervention was associated with changes in these behaviors.

We analysed data from a prospective cohort study of HIV sero-discordant couples in Jinja, Uganda collected between June 2009 and December 2011. Participants received couples counselling, at 3-monthly intervals. We examined trends in reported condom-use, number of concurrent sexual partners, knowledge of HIV serostatus of concurrent partners and condom use of concurrent partners using Generalized Estimating Equation models, comparing responses at study enrollment with responses at six, 12 18 and 24 months of follow-up.

A total of 586 couples were enrolled and the female member was HIV positive in 255 (44%) of them. 
  • The median age for female participants was 35 years and 42 years for men. 
  • Reported condom use at last sex with spouse increased over time with the largest increases found among couples where the positive participant never received ART during the study (an increase from 68.8% at enrollment to 97.1% at 24 months). 
  • Male participants reported reductions in the number of concurrent sexual partners (p<0.001), increase in the knowledge of the HIV serostatus of these partners
  • and a trend towards improved condom-use among non-primary partners (p = 0.070). 
  • Reported reduced risky behaviors did not wane over the study period.

Couples counselling resulted in increased condom use among all participants and among men the intervention resulted in reductions in risk behaviour with concurrent sexual partners. 

Routine counselling for serodiscordant couples should be integrated in routine ART care programs

Effect of Nondisclosure of HIV Status in Sexual Health Clinics on Unlinked Anonymous HIV Prevalence Estimates in England, 2005-2009

To assess the extent of nondisclosure of known HIV status among sexual health clinic attendees and to quantify the impact of nondisclosure on estimates of undiagnosed HIV prevalence and of the proportion of patients remaining undiagnosed on leaving the clinic.

ARVs were detected in 27% of samples taken from 'previously undiagnosed' attendees, who did not have an HIV test but were HIV positive as detected by unlinked anonymous testing, indicating nondisclosure; 24% of such samples from MSM had ARVs present compared with 32% of heterosexual men and women. ARVs were detected in 33% of samples from London clinics and in 21% from non-London clinics. Following adjustment, the estimated prevalence of undiagnosed HIV decreased nonsignificantly from 3.04% to 2.66% among MSM, 0.31% to 0.30% in heterosexual men and 0.40% to 0.37% in women; 7% of MSM who do not have an HIV test at a clinic visit will be infected with HIV and remain unaware of their infection.

Nondisclosure of HIV status to healthcare professionals occurs among clinic attendees. Adjustment for nondisclosure results in a small, nonsignificant decrease in the prevalence of undiagnosed HIV estimated from the unlinked anonymous survey in sexual health clinics. Testing the population of MSM not having an HIV test remains a priority as levels of undiagnosed HIV are high.
