Alcohol Drinking Pattern: A Comparison between HIV-Infected Patients and Individuals from the General Population

Effect of nutrition education on nutritional status and serum zinc level of HIV and AIDS clients: implication for care in resource-limited settings

Background: People living with HIV or AIDS in resource-limited settings are faced with challenges in their nutrition and micronutrient levels. This study aimed to determine the effect of nutrition education on the nutrition status and serum zinc level of HIV and AIDS clients, and its implication for HIV care in resource-limited settings.Methods: This intervention study was conducted among HIV clients at the University of Nigeria Teaching Hospital and Enugu State University Teaching Hospital, which served as the intervention and control groups respectively. A nutrition education programme was delivered to the intervention group. In both groups, before and after the intervention, the body mass index of participants was calculated using their height (m2) and weight (kg) while their serum zinc levels were analysed using spectrophotometry. Chi-square and McNemar chi-square tests were used in the analysis.Results: A total of 185 respondents was studied in each group, with the majority in the 30-39 and 40-49 age groups, respectively (65.4% of the study group and 64.4% of the control group). Larger proportions of respondents in both groups were females (72.4% vs 75.1% respectively). Three months after the intervention, the proportion of respondents with normal serum zinc levels improved significantly from 20.5% to 51.9% in the intervention group (χ²_McNemar, p < 0.001), whereas the control group had no appreciable improvement (16.8% vs 22.7%) (χ²_McNemar, p < 0.117). Furthermore, the post-intervention serum zinc level difference between the intervention and control groups was statistically significant (χ² = 33.699; p < 0.001). No statistically significant difference existed in the nutritional status between the groups (χ² = 3.469; p = 0.325).Conclusion: Nutrition education had a positive effect on the serum zinc levels of HIV clients. Integrating nutrition education programmes as a key component of HIV care in resource-limited settings will help improve the serum zinc level of people living with HIV, which ultimately improves their immune status and life expectancy.

HIV and Substance Use in Latin America: A Scoping Review

This scoping review aims to explore the interplay between substance use (SU) and HIV in Latin America (LA). Database searches yielded 3481 references; 196 were included. HIV prevalence among people who used substances (PWUS) ranged from 2.8–15.2%. SU definitions were variable throughout studies, and thus data were not easily comparable. In 2019, only 2% of new HIV infections were attributed to injection drug use (IDU) in LA. Factors associated with HIV among PWUS included being female, IDU and homelessness, and PWUS were likely to engage in risky sexual behaviors, start antiretroviral treatment late, have poor adherence, have treatment failure, be lost to follow-up, have comorbidities, and experience higher mortality rates and lower quality of life, as has been reported in PLWH with SU in other regions. Five intervention studies were identified, and only one was effective at reducing HIV incidence in PWUS. Interventions in other regions have varying success depending on context-specific characteristics, highlighting the need to conduct more research in the LA region. Though progress has been made in establishing SU as a major concern in people living with HIV (PLWH), much more is yet to be done to reduce the burden of HIV and SU in LA.

Alcohol Use and Abuse Conspires With HIV Infection to Aggravate Intestinal Dysbiosis and Increase Microbial Translocation in People Living With HIV: A Review

The intestinal microbiome is an essential so-called human "organ", vital for the induction of innate immunity, for metabolizing nutrients, and for maintenance of the structural integrity of the intestinal barrier. HIV infection adversely influences the richness and diversity of the intestinal microbiome, resulting in structural and functional impairment of the intestinal barrier and an increased intestinal permeability. Pathogens and metabolites may thus cross the "leaky" intestinal barrier and enter the systemic circulation, which is a significant factor accounting for the persistent underlying chronic inflammatory state present in people living with HIV (PLWH). Additionally, alcohol use and abuse has been found to be prevalent in PLWH and has been strongly associated with the incidence and progression of HIV/AIDS. Recently, converging evidence has indicated that the mechanism underlying this phenomenon is related to intestinal microbiome and barrier function through numerous pathways. Alcohol acts as a "partner" with HIV in disrupting microbiome ecology, and thus impairing of the intestinal barrier. Optimizing the microbiome and restoring the integrity of the intestinal barrier is likely to be an effective adjunctive therapeutic strategy for PLWH. We herein critically review the interplay among HIV, alcohol, and the gut barrier, thus setting the scene with regards to development of effective strategies to counteract the dysregulated gut microbiome and the reduction of microbial translocation and inflammation in PLWH.

Factors associated with viremia in people living with HIV on antiretroviral therapy in Guatemala

INTRODUCTION

Viral suppression prevents HIV transmission and disease progression, but socio-economic and clinical factors can hinder the goal of suppression. We evaluated factors associated with viral non suppression (VNS) and persistent viremia (PV) in people living with HIV (PLHIV) receiving antiretroviral therapy (ART) in Guatemala.

METHODS

We conducted a cross sectional analysis using data from an ongoing cohort of PLHIV attending the largest HIV clinic in Guatemala. Univariable and multivariable analyses were conducted between PLHIV with viral suppression and detectable viremia. VNS was defined as most recent HIV RNA ≥ 200 copies/ml and PV as two consecutive HIV RNA ≥ 200 copies/ml.

RESULTS

Of 664 participants, 13.3% had VNS and 7.1% had PV. In univariable analysis disaggregated by gender, low income, poor education, perceived difficulty attending healthcare, and alcohol use were associated with VNS in men while low CD4 at diagnosis, multiple prior ART regimens and treatment interruptions were significant in both genders. Multiple prior ART regimens (adjusted Odds Ratio (aOR) 2.82, [95% confidence interval (CI) 1.59, 4.99], p < 0.01), treatment interruptions (aOR 4.51, [95% CI 2.13, 9.58], p < 0.01), excessive alcohol consumption (aOR 2.56, [95% CI 1.18, 5.54], p < 0.05) perceived difficulty attending healthcare (aOR 2.07, [ 95% CI 1.25, 3.42], p < 0.01) and low CD4 at diagnosis (aOR 2.34, 95% [CI 1.30, 4.20], p < 0.01) were independently associated with VNS on multivariable regression.

CONCLUSIONS

We conclude that socio-economic and clinical factors influence viral suppression in our cohort and vary between men and women. Gender specific approaches are necessary to achieve the 90% suppression goal.

Worldwide relative smoking prevalence among people living with and without HIV

OBJECTIVE AND DESIGN

People living with HIV (PLH) suffer disproportionately from the chronic diseases exacerbated by smoking tobacco. We performed a systematic review and meta-analysis to establish the relative prevalence of smoking among PLH.

METHODS

We included observational studies reporting current smoking rates among PLH and comparators without HIV. We searched Medline, EMBASE, LILACS and SciELO from inception to 31 August 2019. We excluded studies that recruited participants with smoking related illness. We used a random effects model to estimate the odds ratio for current smoking in PLH and people without HIV. We used the Newcastle--Ottawa scale to assess methodological bias. We performed subgroup analysis based on sex and WHO region. We quantified heterogeneity with meta-regression and predictive distributions. PROSPERO registration:CRD42016052608.

RESULTS

We identified 6116 studies and included 37. Of 111 258 PLH compared with 10 961 217 HIV-negative participants pooled odds of smoking were 1.64 [(95% confidence interval, 95% CI: 1.45-1.85) (95% prediction interval: 0.66-4.10, I2 = 98.1%)]. Odds for men and women living with HIV were 1.68 [(95% CI: 1.44-1.95) (95% prediction interval: 0.71-3.98, I2 = 91.1%)] and 2.16 [(95% CI: 1.77-2.63) (95% prediction interval: 0.92-5.07, I2 = 81.7%)] respectively.

CONCLUSION

PLH are more likely to be smokers than people without HIV. This finding was true in subgroup analyses of men, women and in four of five WHO regions from which data were available. Meta-regression did not explain heterogeneity, which we attribute to the diversity of PLH populations worldwide. Smoking is a barrier to PLH achieving parity in life expectancy and an important covariate in studies of HIV-associated multimorbidity.

Trends, prevalence and factors associated with hypertension and diabetes among South African adults living with HIV, 2005-2017

BACKGROUND

Many people are now living longer with HIV due to access to antiretroviral treatment. In turn, there has been an increase in the burden of hypertension and diabetes. The paucity of data on the burden of hypertension and diabetes in adults living with HIV in South Africa is a public health concern. The paper aimed to describe the prevalence and factors associated with hypertension and diabetes among adults living with HIV (ALHIV).

METHODS

This was a secondary data analysis of the population based on the South African National HIV Prevalence, Incidence, Behaviour and Communication surveys for 2005, 2008 and 2017. Descriptive statistics were used to summarise the characteristics of the study sample. Bivariate and multivariate logistic regression analyses were used to determine factors associated with hypertension and diabetes.

RESULTS

The total study population of ALHIV aged 25 years and older was 978, 1023 and 2483 for 2005, 2008 and 2017. The prevalence of hypertension showed an increasing trend at 11.8% in 2005, 9.5% in 2008 and 14.3% in 2017. The prevalence of diabetes was 3.3% in 2005, 2.8% in 2008 and 3.2% in 2017. Increased odds of hypertension among adults living with HIV were consistently associated with being female and the age group 45 years older across all the survey years, including pensioners and the sick, living in urban areas, high risk of hazardous alcohol consumption, diabetes and heart disease. Increased odds of diabetes were consistently associated with hypertension across all the survey years, including age group 45 years and older, and poor health. While having a secondary level of education and above was protective against diabetes.

CONCLUSION

The study showed that the prevalence of hypertension is high and has increased over time among adults living with HIV while the prevalence of diabetes has remained constant. Findings identified factors consistently associated with the prevalence of both diseases overtime, including contemporary risk factors that should be targeted in the integrated management of chronic disease and HIV care model.

Dangerous liaisons? The role of inflammation and comorbidities in HIV and SARS-CoV-2 infection

INTRODUCTION

In people living with HIV (PLWH), immune activation and inflammation levels are high even when viral suppression is maintained, potentially contributing to several comorbidities, and hampering the immune response to infections such as the recent SARS-CoV-2 disease 2019 (COVID-19).

AREAS COVERED

Immune activation and inflammation play a role in SARS-CoV-2 infection. Severe COVID-19 patients may experience cytokine release syndrome (CRS), leading to alveolar damage, pulmonary fibrinolysis, dysregulated coagulation, and pulmonary injury. Into the systemic circulation, cytokines in excess might leak out of pulmonary circulation, causing systemic symptoms and possibly a multiple-organ dysfunction syndrome. Preexisting comorbidities are also linked to worse COVID-19 outcome: studies suggest that diabetes and hypertension are linked to higher mortality rates. Such comorbidities are more frequent in PLWH, but it is unclear if they have worse outcomes in the case of COVID-19. The literature was searched in PubMed/MEDLINE and EMBASE, and manually in COVID-19 resources.

EXPERT OPINION

A body of evidence shows that HIV and SARS-CoV-2 are able to activate inflammatory pathways, acute in the case of SARS-CoV-2, chronic in the case of HIV, while the comorbidities seem to represent, in the first case, a contributory cause, in the second an effect of the virus-induced damage.

Social support modifies the association between hazardous drinking and depression symptoms among ART clients in Vietnam

INTRODUCTION

Hazardous drinking is widespread among people with HIV (PWH). PWH are also vulnerable to depression due to HIV-related social stigma, and social support can play an important role in improving mental health for this population. No studies have explored whether social support modifies the association of hazardous drinking and depressive symptoms among PWH.

METHODS

We used baseline data from a randomized controlled trial of two evidence-based alcohol reduction interventions among antiretroviral therapy clients in Vietnam. Hazardous alcohol use was defined as having a score ≥8 for men and ≥ 7 for women on the Alcohol Use Disorders Identification Test. The presence of depression symptoms was defined as a score ≥ 5 on the Patient Health Questionnaire-9. Social support was measured with a 5-question modified version of the Medical Outcomes Study Social Support Instrument. Crude (CPRs) and adjusted prevalence ratios (aPRs) of the association were presented.

RESULTS

Hazardous drinking was significantly associated with increased likelihood of having depressive symptoms (aPR = 1.26;95%CI 1.04-1.52). Hazardous drinking and depression symptoms were not associated among those with high social support (aPR = 1.01;95%CI 0.76-1.35), but were associated among those with medium (aPR = 1.24;95%CI 0.92-1.69) and low social support (aPR = 1.71;95%CI 1.25-2.34).

CONCLUSIONS

Social support significantly modified the association between hazardous drinking and depression symptoms among ART clients in Vietnam. Interventions to decrease hazardous alcohol use are broadly indicated for PWH in Vietnam and other low-resource settings, but special attention or modifications may be needed to support mental health among those with lower levels of social support.

Cognitive Reserve Over the Lifespan: Neurocognitive Implications for Aging With HIV

Approximately 59% of adults living with HIV experience HIV-associated neurocognitive disorder, a collection of symptoms and cognitive deficits in various cognitive domains. As the HIV population ages, the prevalence and severity of such cognitive deficits are expected to grow. Understanding how these cognitive deficits manifest is important for nurses and health care providers. This article provides an overview of cognitive reserve and evidence of how it is compromised by HIV, aging, and individual characteristics. Within this context of cognitive reserve, the role of neuroinflammation, neurotoxicity, substance use, comorbidities, depression and anxiety, social isolation, and sedentary lifestyle is reviewed. From this, strategies used to address cognitive deficits are provided, including topics such as psychostimulants, cognitive training, multimodal lifestyle interventions, and compensation strategies. Scenarios of successful and unsuccessful cognitive aging are presented to provide a lifespan perspective of cognitive reserve. Implications for clinical practice and research are provided, as it relates to aging.

Pathogenesis of Aging and Age-related Comorbidities in People with HIV: Highlights from the HIV ACTION Workshop

People with HIV (PWH) experience accentuated biological aging, as defined by markers of inflammation, immune dysfunction, and the epigenetic clock. They also have an elevated risk of multiple age-associated comorbidities. To discuss current knowledge, research gaps, and priorities in aging and age-related comorbidities in treated HIV infection, the NIH program staff organized a workshop held in Bethesda, Maryland in September 2019. This review article describes highlights of discussions led by the Pathogenesis/Basic Science Research working group that focused on three high priority topics: immunopathogenesis; the microbiome/virome; and aging and senescence. We summarize knowledge in these fields and describe key questions for research on the pathogenesis of aging and age-related comorbidities in PWH. Understanding the drivers and mechanisms underlying accentuated biological aging is a high priority that will help identify potential therapeutic targets to improve healthspan in older PWH.

C - reactive protein and interleukin - 6 levels among human immunodeficiency virus -infected patients with dysglycemia in Tanzania

BACKGROUND

Chronic inflammation has been associated with dysglycemia among people living with HIV (PLHIV). There is however, limited data regarding this phenomenon in sub-Sahara Africa (SSA). Therefore we assessed the levels of C-reactive protein (CRP) and Interleukin 6 (IL-6) on a cohort of PLHIV and its associations with dysglycemia in Tanzania.

METHODS

We conducted a cross-sectional study at the Infectious Disease Clinic (IDC) in Tanzania from March to May 2018. Purposive sampling was used to identify participants who had an undetectable viral load, were on 1st line anti-retroviral therapy (ART) and had an overnight fast. The WHO stepwise approach for non-communicable disease (NCD) surveillance was used to collect data. Fasting blood glucose and blood glucose after 75 g oral glucose load was measured, and Enzyme-linked immunosorbent assay (ELISA) was used to test for inflammatory markers (IL-6 and CRP). Associations were explored using the Chi square test and binary logistic regression was performed to estimate the odds ratios. A p-value less than 0.05 was considered statistically significant.

RESULTS

A total of 240 participants were enrolled. Forty two percent were overweight/obese (> 25 kg/m²), 89% had a high waist to height ratio. The median ART duration was 8(5-10) years. The prevalence of dysglycemia among our cohort of PLHIV was 32%. High CRP was associated with a 2.05 increased odds of having dysglycemia OR 2.05 (1.15-3.65) (p = 0.01). Taking stavudine was associated with a 1.99 odds of having dysglycemia OR 1.99 (1.04-3.82) (p = 0.03).We did not find a significant association between IL-6 and dysglycemia.

CONCLUSION

High CRP and taking stavudine were significantly associated with dysglycemia among PLHIV with undetectable viral load.

A comparison of socio-behavioral risk factors between HIV-infected and non-infected older adults in Northern Thailand

There is a shift in the demographic profile of people living with HIV toward older age groups. The current study compares alcohol use, smoking, and physical exercise between HIV-infected and non-infected older adults recruited in 12 community hospitals in Chiang Mai Province, Northern Thailand. Participants in the two groups were 50 years and above, matched by age and gender. The sample included 364 participants in each of the groups. Older adults living with HIV were less likely to report drinking alcohol in the past year (AOR, 0.55; CI, 0.34-0.89, P = 0.015) and more likely to report being currently engaged in physical activities (AOR, 2.58; CI, 1.77-3.76, P < 0.001). There was no difference between the two groups in terms of "current smoking status". Older adults living with HIV were healthier than their non-infected counterparts in terms of the socio-behavioral risks.

Mechanisms of Arrhythmia and Sudden Cardiac Death in Patients With HIV Infection

Long-term survival of HIV-infected patients has significantly improved with the use of antiretroviral therapy (ART). As a consequence, cardiovascular diseases are now emerging as an important clinical problem in this population. Sudden cardiac death is the third leading cause of mortality in HIV patients. Twenty percent of patients with HIV who died of sudden cardiac death had previous cardiac arrhythmias including ventricular tachycardia, atrial fibrillation, and other unspecified rhythm disorders. This review presents a summary of HIV-related arrhythmias, associated risk factors specific to the HIV population, and underlying mechanisms. Compared with the general population, patients with HIV have several cardiac conditions and electrophysiological abnormalities. As a result, they have an increased risk of developing severe arrhythmias, that can lead to sudden cardiac death. Possible explanations may be related to non-ART polypharmacy, electrolyte imbalances, and use of substances observed in HIV-infected patients; many of these conditions are associated with alterations in cardiac electrical activity, increasing the risk of arrhythmia and sudden cardiac death. However, clinical and experimental evidence has also revealed that cardiac arrhythmias occur in HIV-infected patients, even in the absence of drugs. This indicates that HIV itself can change the electrophysiological properties of the heart profoundly and cause cardiac arrhythmias and related sudden cardiac death. The current knowledge of the underlying mechanisms, as well as the emerging role of inflammation in these arrhythmias, are discussed here.

Substance use patterns among women living with HIV compared with the general female population of Canada

BACKGROUND

HIV infection and substance use synergistically impact health outcomes of people with HIV. In this study, we assessed the prevalence of substance use among women living with HIV (WLWH) and compared them with expected values from general data.

METHODS

Cigarette smoking, frequency of alcohol consumption, last-month non-prescribed cannabis use (vs. last-year use), and last 3 months regular (≥once/week) and occasional (<once/week) use of crack/cocaine, speed (amphetamine), and heroin (vs. last-year use) were examined in WLWH from the 2013-2015 Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS; N = 1422) and compared with general population women from the 2013-2014 Canadian Community Health Survey (CCHS; N = 46,831). Age/ethnoracial-standardized prevalence differences (SPD) and 95% confidence intervals (CI) were reported.

RESULTS

Compared to expected estimates from general population women, a higher proportion of WLWH reported daily cigarette smoking (SPD: 26.8% [95% CI: 23.9, 29.7]), smoking ≥20 cigarettes/day (SPD: 11.6% [9.8, 13.6]), regular non-prescribed cannabis use (SPD: 8.0% [4.1, 8.6]), regular crack/cocaine use (SPD: 16.7% [13.1, 20.9]), regular/occasional speed use (SPD: 2.4% [1.2, 4.7]), and heroin use (SPD: 11.2% [8.3, 15.0]). However, WLWH reported lower frequencies of alcohol consumption and binge drinking than their counterparts in the general population.

CONCLUSIONS

Cigarette smoking and illicit drug use, but not alcohol use or binge drinking, were more prevalent in WLWH than would be expected for Canadian women with a similar age and ethnoracial group profile. These findings may indicate the need for women-centered harm reduction programs to improve health outcomes of WLWH in Canada.

Cost-effective osteoporosis treatment thresholds for people living with HIV infection in Greece

OBJECTIVES

We aimed to specifically define the FRAX-based cost-effective treatment thresholds for osteoporosis among people living with HIV (PLWHIV) in Greece and to compare them with those of the general population.

METHODS

A previously described state transition Markov cohort model was used in order to estimate the cost-effective intervention thresholds for osteoporotic therapy among Greek PLWHIV employing the FRAX® tool. The model-derived relative risk at which an incremental cost-effectiveness ratio of 30,000€/QALY gained was observed for treatment versus no intervention was multiplied by the average Greek FRAX-based 10-year probabilities for both major osteoporotic and hip fractures.

RESULTS

There exists no significant difference in the cost-effective FRAX® based thresholds between PLWHIV and general population. The absolute 10-year probabilities of 2.5 and 10% for hip and major osteoporotic fractures, respectively, could be used for the initiation of treatment for PLWHIV of both genders under the age of 75; for older subjects the proposed intervention threshold is raised to 5 and 15% 10-year probability for hip and major osteoporotic fracture, respectively.

CONCLUSIONS

Our study confirms the general recommendation for the use of country specific FRAX® thresholds when managing bone fragility within PLWHIV. In any case, clinical judgment and appropriate screening are mandatory and irreplaceable.

Socio-behavioral risk factors among older adults living with HIV in Thailand

BACKGROUND

There has been a global increase in HIV infection in persons 50 years of age and older. This group is at risk for development of chronic illness that may be exacerbated by socio-behavioral risk factors such as smoking, unhealthy alcohol use, and sedentary lifestyle. However, socio-behavioral risk factors in this older HIV infected population are not well described. The current study aims to describe and document factors related to alcohol use, tobacco smoking, and physical exercise in older adults living with HIV (OALHIV).

METHODS

This cross-sectional quantitative study was conducted between August and September 2015, and enrolled HIV-infected participants aged 50 years and older from 12 community hospitals in Chiang Mai Province, Northern Thailand.

RESULTS

Of the 364 participants recruited in the study, 57.1% were female, and 67.3% were between 50-59 years of age. Respectively, 15.1%, 59.1%, and 18.7% were current smokers, currently engaged in physical exercises, and reported ever drank alcohol in the past year. 22.1% of those who drank alcohol reported experience of heavy episodic drinking. Male gender was one of the strongest predictors of ever drank alcohol in the past year (AOR, 4.66; CI, 2.28-9.49; P<0.001) and of being a current smoker (AOR, 13.41; CI, 7.23-24.87; P<0.001). Lower household income was associated with increased odds of ever drank alcohol in the past year (household income (1 USD = 35 THB) of ≤ 5,000 Baht versus > 20,000 Baht: AOR, 5.34; CI, 1.28-22.25; P = 0.021). Lower educational level was associated with decreased odds of physical exercises (no education versus secondary and higher: AOR, 0.22; CI, 0.08-0.55; P = 0.001).

CONCLUSION

Smoking and alcohol use is common among OALHIV, with a substantial proportion not engaging in physical exercises. Interventions for OALHIV should particularly target males and those of lower socio-economic status to deter smoking and alcohol use and to promote physical exercises.

Identifying the Intersection of Alcohol, Adherence and Sex in HIV Positive Men on ART Treatment in India Using an Adapted Timeline Followback Procedure

People living with HIV (PLHIV) on anti-retroviral treatment (ART) who drink are less adherent and more likely to engage in unprotected sex but the connections among these events are correlational. Using an adapted Timeline Follow-Back (A-TLFB) procedure, this paper examines the day by day interface of alcohol, medication adherence and sex to provide a fine grained understanding of how multiple behavioral risks coincide in time and space, explores concordance/discordance of measures with survey data and identifies potential recall bias. Data are drawn from a survey of behavior, knowledge and attitudes, and a 30 day TLFB assessment of multiple risk behaviors adapted for the Indian PLHIV context, administered to 940 alcohol-consuming, HIV positive men on ART at the baseline evaluation stage of a multilevel, multi-centric intervention study. On days participants drank they were significantly more likely to be medication non-adherent and to have unprotected sex. In the first day after their alcohol consuming day, the pattern of nonadherence persisted. Binge and regular drinking days were associated with nonadherence but only binge drinking co-occurred with unprotected sex. Asking about specific "drinking days" improved recall for drinking days and number of drinks consumed. Recall declined for both drinking days and nonadherence from the first week to subsequent weeks but varied randomly for sex risk. There was high concordance and low discordance between A-TLFB drinking and nonadherence but these results were reversed for unprotected sex. Moving beyond simple drinking-adherence correlational analysis, the A-TLFB offers improved recall probes and provides researchers and interventionists with the opportunity to identify types of risky days and tailor behavioral modification to reduce alcohol consumption, nonadherence and risky sex on those days.

Marijuana use and HIV treatment outcomes among PWH receiving care at an urban HIV clinic

BACKGROUND

While marijuana use is prevalent among persons with HIV (PWH), few studies have examined the relationship between marijuana use and HIV treatment outcomes independent of alcohol and other drug use.

METHODS

We conducted a prospective cohort study to examine the relationships between frequency of marijuana use and antiretroviral therapy (ART) adherence and viral suppression in patients enrolled in the Johns Hopkins HIV Clinical Cohort between September 2013 through November 2015 (N=1377). We categorized marijuana use as no use, none in the last 3months, monthly use or less, weekly/daily. Our outcomes of interest were use of ART, ≥90 ART adherence, and viral suppression (HIV1-RNA<200 copies). We conducted multivariable analyses to examine associations between the frequency of marijuana use and our treatment outcomes, using generalized estimating equations to account for repeated measures. Other independent variables of interest included alcohol use, other drug use, and depressive symptoms. Analyses were adjusted for age, race, sex and HIV acquisition risk factor.

RESULTS

In multivariable analyses we found no statistically significant association between frequency of marijuana use and our treatment outcomes. Alcohol use, other drug use and depressive symptoms were associated with lower odds of ART adherence and viral suppression.

CONCLUSIONS

In this sample of PWH in care, frequency of marijuana use independent of other substance use does not appear to be associated with negative HIV treatment outcomes. Our results indicate that unlike alcohol, other substances and depression, marijuana use may not be a barrier to the effective treatment of HIV.
