Cannabis use frequency and pain interference among people with HIV.

Cannabis is often used by people with HIV (PWH) for pain, yet study results are inconsistent regarding whether and how it affects pain. This study examines whether greater cannabis use frequency is associated with lower pain interference and whether cannabis use modifies the association of pain severity and pain interference among 134 PWH with substance dependence or a lifetime history of injection drug use. Multi-variable linear regression models examined the association between past 30-day cannabis use frequency and pain interference. Additional models evaluated whether cannabis use modified the association between pain severity and pain interference. Cannabis use frequency was not significantly associated with pain interference. However, in a model with interaction between cannabis use frequency and pain severity, greater cannabis use frequency attenuated the strength of the association between pain severity and pain interference (p = 0.049). The adjusted mean difference (AMD) in pain interference was +1.13, + 0.81, and +0.05 points for each 1-point increase in pain severity for those with no cannabis use, 15 days of use, and daily use, respectively. These findings suggest that attenuating the impact of pain severity on pain-related functional impairment is a potential mechanism for a beneficial role of cannabis for PWH.

Medication for addiction treatment and acute care utilization in HIV-positive adults with substance use disorders.

Medication for addiction treatment (MAT) could reduce acute care utilization in HIV-positive individuals with substance use disorders. The study objective was to determine if HIV-positive people with substance use disorders treated with MAT report less acute care utilization than those not receiving MAT. We assessed the association between MAT and acute care utilization among HIV-positive individuals with alcohol or opioid use disorder. Acute care utilization 6 months later was defined as any past 3-month self-reported (1) emergency department (ED) visit and (2) hospitalization. Of 153 participants, 88% had alcohol use disorder, 41% had opioid use disorder, and 48 (31%) were treated with MAT. Fifty-five (36%) participants had an ED visit and 38 (25%) participants had a hospitalization. MAT was not associated with an ED visit (AOR 1.12, 95% CI 0.46-2.75) or hospitalization (AOR 1.09, 95% CI 0.39-3.04). MAT was not associated with acute care utilization. These results highlight the need to increase MAT prescribing in HIV-positive individuals with substance use disorders, and to address the many factors that influence acute care utilization.

Evolution of illicit opioid use among people with HIV infection in St Petersburg, Russia, in the period 2004-2015.

OBJECTIVES: In the late 1990s, when the current Russian opioid epidemic began, illicit opioids used in Russia consisted almost exclusively of heroin. The type of opioids used has evolved in the early 21st Century. The objective of this study was to describe the evolution of illicit opioid use among people living with HIV (PLWH) reporting recent opioid use in St Petersburg, Russia. METHODS: We examined baseline data from four research studies conducted in the period 2004-2015 that included PLWH who used opioids [Partnership to Reduce the Epidemic Via Engagement in Narcology Treatment (PREVENT; 2004-2005; n = 17), HIV Evolution in Russia-Mitigating Infection Transmission and Alcoholism in a Growing Epidemic (HERMITAGE; 2007-2010; n = 281), Linking Infectious and Narcology Care (LINC; 2013-2014; n = 119) and Russia Alcohol Research Collaboration on HIV/AIDS (Russia ARCH; 2012-2015; n = 121)] and reported recent use of heroin and other opioids. RESULTS: Although these studies spanned more than a decade, the participants represented similar birth cohorts; the mean age was 24.5 years in 2004 and 33.3 years in 2014. The use of opioid types, however, evolved across cohorts, with the use of any illicit drug other than heroin increasing from 6% [95% confidence interval (CI) 000.2, 29%] in PREVENT (2004-2005) to 30% (95% CI 25, 36%) in HERMITAGE (2007-2010) to 70% (95% CI 61, 78%) in LINC (2013-2014) to 77% (95% CI 68, 84%) in ARCH (2012-2015). Any heroin use consistently decreased over the 10-year period in the cohorts, from 100% (95% CI 80, 100%) in 2004-2005 to 54% (95% CI 44, 63%) in 2012-2015. CONCLUSIONS: Among PLWH who use opioids in St Petersburg, Russia, illicit use of opioids other than heroin appears to be more common than heroin use.

Sexually transmitted infections among HIV-infected heavy drinkers in St Petersburg, Russia.

The objective of this study was to estimate the prevalence and identify correlates of four sexually transmitted infections (STIs) among HIV-infected Russians reporting heavy alcohol use and recent unprotected sex, we conducted a cross-sectional analysis of baseline data from the HERMITAGE study. The primary outcome was any current STI, based on urine tests for Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis and serological testing for infection with Treponema pallidum. Data on potential demographic and behavioural predictors of STI were obtained from surveys administered at study entry. Of 682 participants, 12.8% (95% confidence interval [CI] 10.3, 15.3) tested positive for at least one STI. In a multivariable model adjusted for gender, age and marital status, only sex trade involvement over the last three months was significantly associated with an increased odds of STI (adjusted odds ratio [AOR] 2.00, 95% CI 1.13, 3.55). Given that STIs were common in this HIV-infected cohort, and that few patient characteristics predicted STI, the current practice of screening HIV-infected Russians for syphilis alone merits re-evaluation.

Illicit drugs, alcohol, and addiction in human immunodeficiency virus.

Drug and alcohol use complicate both the prevention and treatment of human immunodeficiency virus (HIV) infection. Substance use is one of the major engines driving HIV transmission, directly, through the sharing of injection drug use equipment and indirectly, through increasing risky sexual behaviors. Drug and alcohol dependence compromise effective HIV treatment by influencing both access and adherence to antiretroviral therapy. Exposure to addictive substances may have direct immunosuppressive effects independent of their impact on access and adherence to treatment. Measures effective at minimizing HIV transmission attributable to drug and alcohol use include HIV testing and referral to treatment, syringe and needle exchange programs, opioid replacement therapy (i.e., methadone and buprenorphine), and behavioral interventions targeting HIV risk behaviors among both HIV-infected and HIV-uninfected people. Measures effective at optimizing HIV treatment among alcohol and drug-dependent patients include HIV testing with referral to treatment and substance use treatment that is linked to or integrated into HIV treatment. Due to the intertwining problems of substance use and HIV infection, physicians and other health care providers must address the issues of illicit drugs and alcohol use as mainstream medical problems in order to provide optimal care for HIV-infected patients.

Older, hypertensive, and hypercholesterolemic fairgoers visit more booths and differ in their health concerns at a community health fair.

The purpose of this study was to determine whether persons attending a community health fair had different health concerns and booth visitation patterns based on their risk factor profiles. All fairgoers were encouraged to complete an anonymous survey of demographic information, top 4 health concerns, and selected cardiac risk factors. Over the five-hour duration of the fair, 329 surveys were collected from about 450 fairgoers. There were no exclusion criteria for the survey. The fair was sponsored by the Maryland Chapter of the American College of Physicians, organized by medical students from the University of Maryland and Johns Hopkins University, and included 23 booths on a variety of health topics. Older fairgoers and fairgoers with a self-reported history of high blood pressure or elevated cholesterol showed an increased interest in hypertension and heart disease (p < 0.05). Older fairgoers also showed an increased interest in health topics related to aging, such as estrogen replacement therapy and geriatric medicine. Older, hypertensive and hypercholesterolemic fairgoers visited an increased mean number of total booths when compared to other respondents (p < 0.05). Most booths reported a higher percentage of older, hypertensive, and hypercholesterolemic visitors than the overall percentage of fairgoers who reported these risk factors. These results suggest that booth visitation patterns of health fair participants may be viewed as a deliberate attempt by at risk populations to access health information particular to their needs.
