HIV and Substance Use in Latin America: A Scoping Review

Cocaine/crack and cannabis use among transgender women in Goiás, Central Brazil

INTRODUCTION

Illicit drug use is a significant public health problem. Studies have shown a high prevalence of cocaine and cannabis use in transgender women (TGW).

OBJECTIVE

To describe the consumption patterns of cannabis and cocaine/crack use and variables associated with their use in TGW in Central Brazil.

METHODS

A cross-sectional study was conducted on TGW in Goiás, Brazil. Participants were recruited using a respondent-driven sampling method and were interviewed face-to-face about cannabis and crack-cocaine and the variables associated with them. The Alcohol Smoking and Substance Involvement Screening Test was used to assess substance use. Unweighted logistic regression was used to identify variables associated with cannabis and crack cocaine use. P-values < 0.05 were considered statistically significant.

RESULTS

A total of 440 transgender women participated in the study. Their median age was 25 years (interquartile range: 20.5-29.5 years). Most participants were single (85.5%) and had engaged in sex work in their lifetime (58.6%). Cannabis was reported by 68.9% and 53.4% of participants in their lifetime and in the past three months, respectively, and cocaine/crack use was reported by 59.8% and 44.1% of participants in their lifetime and the past three months, respectively. Of the participants, 10.2% reported high-risk cannabis use, and 9.1% reported high-risk cocaine/crack use. Furthermore, 35% of participants reported using both drugs. Previous physical violence (Adjusted Odds Ratio (AOR): 2.37), inconsistent condom uses during anal sex (AOR: 2.17), and moderate-/high-risk cocaine/crack use (AOR: 3.14) were associated with high-risk cannabis use. Previous sexual violence (AOR: 2.84), previous STI (AOR: 2.90), moderate-/high-risk cannabis (AOR: 3.82), and binge drinking (AOR; 3.28) were associated with high-risk cocaine/crack use.

CONCLUSION

Our study found a high frequency, significant overlap in the use of cannabis and cocaine/crack use and violence associated with these drugs consumption among TGW, highlighting the urgent need for health policies for drug disorders among this socially marginalized group.

Effect of HIV and substance use disorder comorbidity on the placenta, fetal and maternal health outcomes: systematic review and meta-analysis protocol

BACKGROUND

Substance use disorders and HIV infection have a bidirectional relationship. People who use illicit drugs are at increased risk of contracting HIV/AIDS, and people living with HIV/AIDS are at increased risk of using substances due to disease-related complications like depression and HIV-associated dementia. There is no adequate evidence on the effect of HIV/AIDS and substance use disorder comorbidity-related effects on placental, fetal, maternal and neonatal outcomes globally.

METHODS AND ANALYSIS

We will search articles written in the English language until 30 January 2024, from PubMed/Medline, Cochrane Library, Embase, Scopus, Web of Sciences, SUMsearch2, Turning Research Into Practice database and Google Scholar. A systematic search strategy involving AND/OR Boolean Operators will retrieve information from these databases and search engines. Qualitative and quantitative analysis methods will be used to report the effect of HIV/AIDS and substance use disorders on placental, fetal and maternal composite outcomes. Descriptive statistics like pooled prevalence mean and SD will be used for qualitative analysis. However, quantitative analysis outcomes will be done by using Comprehensive Meta-Analysis Software for studies that are combinable. The individual study effects and the weighted mean difference will be reported in a forest plot. In addition to this, the presence of multiple morbidities like diabetes, chronic kidney disease and maternal haemoglobin level could affect placental growth, fetal growth and development, abortion, stillbirth, HIV transmission and composite maternal outcomes. Therefore, subgroup analysis will be done for pregnant women with multiple morbidities.

ETHICS AND DISSEMINATION

Since systematic review and meta-analysis will be conducted by using published literature, ethical approval is not required. The results will be presented in conferences and published in peer-reviewed journals.

Promoting HIV care continuum outcomes among people who use drugs and alcohol: a systematic review of randomized trials evaluating behavioral HIV care interventions published from 2011 to 2023

BACKGROUND

Substance use remains a robust predictor of HIV infection and a serious impediment to HIV care continuum progression for people living with HIV. The primary research question of this systematic review is focused on understanding the extent to which behavioral HIV care interventions have been efficacious in helping people who live with HIV and who use substances along the HIV care continuum.

METHODS

Using PubMed and ProQuest databases, we performed a systematic review of randomized trials of behavioral HIV care continuum interventions among people who use substances published from 2011 to August 2023, since the beginning of the treatment-as-prevention era.

RESULTS

We identified 11 studies (total participants: N = 5635), ten intentionally targeting substance-using populations. Four studies involved samples using ≥ 1 substance (e.g., alcohol, opioids, stimulants, marijuana); four involved injection drug use; one involved methamphetamine use; and one involved alcohol use. One study targeted a population with incidental substance use (i.e., alcohol, injection drug use, non-injection drug use reported in most participants). Each study defined one or more HIV care outcomes of interest. Viral suppression was an outcome targeted in 9/11 studies, followed by uptake of antiretroviral therapy (ART; 7/11), ART adherence (6/11), retention in care (5/11), and linkage to care (3/11). While most (nine) of the studies found significant effects on at least one HIV care outcome, findings were mostly mixed. Mediated (2/11) and moderated (2/11) effects were minimally examined.

CONCLUSIONS

The results from this systematic review demonstrate mixed findings concerning the efficacy of previous HIV care interventions to improve HIV care continuum outcomes among people who use substances. However, heterogeneity of study components (e.g., diversity of substances used/assessed, self-report vs. objective measures, attrition) prevent broad deductions or conclusions about the amenability of specific substance-using populations to HIV care intervention. More coordinated, comprehensive, and targeted efforts are needed to promote and disentangle intervention effects on HIV care continuum outcomes among substance-using populations.

SEROPREVALENCE OF HBsAg, Anti-HBs, Anti-HCV, and Anti-HIV IN PATIENTS WITH ALCOHOL AND SUBSTANCE ABUSE IN AN AMATEM CLINIC IN EASTERN TURKIYE: A SIX-YEAR RETROSPECTIVE EVALUATION

Aim Substance abuse and concomitant infections are important causes of morbidity and mortality. Yet, the number of epidemiological studies regarding infectious diseases in people with substance abuse are limited in our country. In this study, the aim was to investigate the frequency of illegal alcohol and substance use in an Alcohol and Drug Research, Treatment and Training Centres (AMATEM) clinic in Turkey as well as the HBsAg, anti-HBs, anti-HCV, and anti-HIV parameters between the years of 2016-2021. Material and Method HBsAg, anti-HBs, anti-HCV, and anti-HIV tests were conducted using the ELISA technique in 6881 alcohol and substance use disorder (ASUD). Urine samples from ASUD’s were analyzed for alcohol, cannabis, and cocaine metabolites. The results were evaluated retrospectively. Results All of the 6881 ASUD’s were male with a mean age of 32.18±9.66 years. Of the 6881 ASUD’s included in the study, 4107 (59.7%) were opioid addicts; 1479 (21.5%) were mixed drug addicts; 897 (13%) were alcohol addicts; and the rest were addicts with other types of substance use. The mean age of the alcohol users was 45.33±13.03 and the mean age of opioid users was 29.90±7.13. The percentage of opioid addiction in 2016 was 71.2% which dropped to 28.7% in 2021. Meanwhile, the percentage of alcohol addiction was 13.6% in 2016 and increased to 21.4% in 2021; and the percentage of mixed drug use was 8.7% in 2016 and increased to 36.8% in 2021. HBsAg-positivity in opioid users (56.7%) was higher compared to cannabis users (2.6%) and mixed drug users (22.3%). Anti-HCV positivity of opioid users (69.4%) was found to be higher compared to alcohol (9.4%), cannabis (2%), and mixed drug (16.2%) users, and this finding was statistically significant (p=0.0001). Anti-HBs positivity of opioid users (63.1%) was found to be higher compared to alcohol (9.9%), cannabis (3%), and mixed drug (21%) users, and this finding was statistically significant (p=0.0001). Anti-HIV was determined negative in all ASUD’s. The highest rates of HBsAg, anti-HCV and anti-HBs positivity were found in the 26-30 years of age. Conclusion These findings indicate a high prevalence of intravenous substance abuse in the 26-30 years age group in our region as well as the high HBV and HCV rates in this patient group.
