“…(2) Heavy alcohol use and stimulant drug use have been associated with increased HIV acquisition among MSM(3) and the general population in the United States. (4) Crystal methamphetamine use, in particular, has been associated with low rates of condom use and increased numbers of sexual partners(5,6), as well as with incident HIV infection. (3,7) Furthermore, alcohol and stimulant use have been associated with decreased adherence to antiretroviral therapy among MSM living with HIV(8,9), which may result in reduced viral suppression and increased HIV transmission within networks of substance users.…”

Differences in Attitudes About HIV Pre-Exposure Prophylaxis Use Among Stimulant Versus Alcohol Using Men Who Have Sex with Men

Alcohol and stimulant use are independently associated with increased HIV acquisition among men who have sex with men (MSM). We assessed differences in acceptability and perceived barriers to uptake of pre-exposure prophylaxis (PrEP) among stimulant and alcohol-using MSM in Boston. From September 2012–2013, a quantitative assessment was conducted with 254 MSM respondents who reported recent condomless sex in the context of concurrent stimulant (crack/cocaine and crystal methamphetamine; n=132) or alcohol use (n=122). Thirteen (5.1%) reported previous PrEP use. In multivariable models, stimulant users were more likely to be concerned that substance use would affect PrEP adherence (aRR=2.79, 95% CI 1.63–4.77), and were less concerned about HIV stigma as a barrier to PrEP uptake (aRR=0.52, 95% CI 0.30–0.90) compared to alcohol users. Barriers to PrEP uptake and adherence differ by type of substance used. Different strategies may be required for PrEP implementation among MSM who use stimulants and alcohol.

“…(Benotsch et al, 2012; Buchacz et al, 2005; Mimiaga et al, 2012b) In addition to event-level crystal methamphetamine use, individuals who had a chronic crystal methamphetamine use disorder more frequently reported UAI as the potential exposure that led to seeking PEP. Crystal methamphetamine-using MSM were also more frequently prescribed 3-drug regimens, likely due to the providers’ perception of especially high-risk exposures.…”

“…(Colfax and Shoptaw, 2005; Mimiaga et al, 2012b) It has been well established that crystal methamphetamine use is predictive of higher risk sexual encounters, including low rates of condom use, an increase in number of sexual partners, including anonymous partners, and prolonged sexual encounters spanning multiple days.

Background Men who have sex with men (MSM) who use crystal methamphetamine (CM) are at increased risk for HIV infection. Post-exposure prophylaxis (PEP) is a useful HIV prevention strategy if individuals are able to identify high-risk exposures and seek timely care, however to date there has been limited data on the use of PEP by CM users. Methods A retrospective cohort study of all PEP prescriptions (N=1,130 prescriptions among 788 MSM) at Fenway Community Health in Boston, MA was undertaken. Multivariable models were used to assess the association between CM use during exposure (7.4% used CM during exposure) and chronically (7.4% of MSM were chronic CM users) and individual-level and event-level outcomes among MSM who used PEP at least once. Results Compared to those who had not used CM, MSM PEP users who used CM more frequently returned for repeat PEP (aOR 5.13, 95%CI 2.82 to 9.34) and were significantly more likely to seroconvert over the follow-up period (aHR 3.61, 95%CI 1.51 to 8.60). MSM who used CM had increased odds of unprotected anal intercourse as the source of exposure (aOR 2.12, 95%CI 1.16 to 3.87) and knowing that their partner was HIV infected (aOR 2.27, 95%CI 1.42 to 3.64). Conclusions While MSM who use CM may have challenges accessing ART in general, these data highlight the fact that those who were able to access PEP subsequently remained at increased risk of HIV seroconversion Counseling and/or substance use interventions during the PEP course should be considered for CM-using MSM.

“…Among communities of MSM who misuse stimulants, a series of health conditions co-occur (Beyrer et al, 2012; Mimiaga et al, 2015) with corresponding and increased rates of condomless sex (Freeman et al, 2011; Boone, Cook and Wilson, 2013, Benotsch, Lance, Nettles, and Koester, 2012) and risks for HIV infection (Koblin et al, 2006; Plankey et al, 2007; Ostrow et al, 2009). …”

Stimulant use rates are higher among men who have sex with men (MSM) than the general population. Contingency management (CM) may be an effective intervention for reducing stimulant use in this population. To specify both the mechanism and temporal effects of contingent reward on behavior change, logistic growth trajectory modeling (LGTM) was used to contrast a non-contingent matched rewards condition (i.e., non-contingent yoked controls; NCYC) to a voucher-based CM intervention (maximum= $430) to reduce stimulant use among MSM. Stimulant-using MSM were randomized to either a CM intervention (n=70) or a NCYC condition (n=70). Results from a LGTM (analytical sample n=119; nCM=61; nNCYC=58) indicated four distinct intervention response patterns: responders (i.e., predicted > 90% stimulant metabolite-free urinalyses; 64.7% of sample); worsening intervention response (14.3%); non-responders (12.6%); and, single-positive (8.4%); all estimated trajectory coefficients were significant at p < 0.03 (2-tailed). Participants receiving CM were significantly overrepresented in the responder (64%) and single-positive (80%) categories (χ2(3) = 29.04; p < 0.001); all non-responders and 76.5% of the worsening intervention response category were in the NCYC condition. Results demonstrate the utility of trajectory modeling and further support the contingent application of reward as the operative mechanism associated with patterns of stimulant abstinence with CM applied to a sample of stimulant-using MSM outside the context of formal drug treatment.

Attitudes Toward Methamphetamine Use and HIV Risk Behavior in Men Who Have Sex with Men

Abstract: Results suggest that prevention efforts may benefit from targeting the minority of methamphetamine users who perceive methamphetamine as enhancing sexual activity and use it for this purpose.
