RESUMO

INTRODUCTION: While research with sexual minority men (SMM) has focused on disparities related to HIV, substance use and mental health, synergistic psychosocial pathways driving these epidemics remain underexplored. We used syndemic theory to assess how psychosocial factors sustain methamphetamine use and hinder recovery efforts for SMM living with HIV. METHODS: A triangulation of network analyses and constructivist grounded theory approaches is utilised to elucidate pathways through which psychosocial factors influence methamphetamine use among this population. Survey data (N = 129) are used for quantitative analyses and a purposive sub-sample (n = 24) was recruited for semi-structured interviews for qualitative analyses. FINDINGS: The network analysis revealed two statistically significant bivariate associations: between post-traumatic stress disorder and depression symptoms (b = 0.37, SD = 0.07, 95% confidence interval [0.23, 0.49]) and between depression symptoms and negative affect (b = 0.26, SD = 0.07, 95% confidence interval [0.12, 0.38]). Findings from the constructivist grounded theory analysis supplement the network analysis by offering a nuanced take on how negative affect, post-traumatic stress disorder, and depression symptoms operate synergistically to promote methamphetamine use and impede recovery efforts. DISCUSSION AND CONCLUSIONS: Participants relay experiences of using methamphetamine to cope with these psychosocial factors through avoidance, escapism, mood elevation, and numbing of emotions. Findings suggest that centring these psychosocial factors may inform more effective, holistic interventions for this high-priority population.

RESUMO

BACKGROUND: Although people with HIV have a markedly higher risk of anal squamous cell carcinoma (ASCC), there are few evaluations of anal Pap screening determinants within safety-net HIV clinics. METHOD: We conducted an evaluation of anal Pap screening correlates within a safety-net HIV clinic in Miami. Medical records were reviewed for 298 people ages 45 and older receiving HIV primary care. Demographic information and the prevalence of anal Pap screening over 1 year (i.e., 2018-2019) were extracted. RESULTS: Between 2018 and 2019, approximately half (46%) of patients completed anal Pap screening although this varied by sex assigned at birth. More than three-fourths of females (77%) compared to one-fourth (23%) of males were screened between 2018 and 2019 (p < 0.0001). CONCLUSION: Findings underscore the need for multi-level intervention approaches to optimize anal Pap screening among males with HIV within the Miami-based safety-net clinic.

RESUMO

BACKGROUND: There is clear evidence that loneliness and social isolation have profound health consequences. Documenting the associations of loneliness and social isolation with inflammatory bowel disease (IBD) symptoms, disease severity, and treatment outcomes could meaningfully improve health and quality of life in patients with IBD. PURPOSE: The purpose of this narrative review was to synthesize the empirical evidence on the associations of loneliness and social isolation with IBD symptoms, disease severity, and treatment outcomes. METHODS: Articles were identified through systematic database searches. Quantitative studies that enrolled patients with IBD were included if they examined one of the following outcomes: (a) loneliness or social isolation or (b) IBD-related symptoms, disease severity, or treatment outcomes. RESULTS: We identified 1,816 articles after removing duplicates. Of the 18 studies that met the inclusion criteria, 15 were cross-sectional and 3 were longitudinal. Overall, studies found that loneliness was associated with greater disease activity, functional gastrointestinal symptoms, IBD illness stigma, depressive symptoms, daily IBD symptom burden, reduced resilience, and poorer quality of life. Social isolation was associated with higher prevalence of IBD hospitalizations, premature mortality, and depression. CONCLUSIONS: Findings suggest that loneliness and social isolation are associated with poorer health and quality of life in patients with IBD. Prospective cohort studies examining the biobehavioral mechanisms accounting for the associations of loneliness and social isolation with IBD-related outcomes are needed to guide the development of psychological interventions for individuals living with IBD.


This article explores the connection between loneliness, social isolation, and health outcomes in people with inflammatory bowel disease (IBD). While loneliness and social isolation are known to negatively impact health in other chronic diseases, their specific effects within IBD have been far less studied. This study conducted a narrative review and found that loneliness is linked to more severe IBD symptoms, including increased disease activity, greater gastrointestinal distress, and lower quality of life. Similarly, social isolation is associated with higher rates of IBD-related hospitalizations, depression, and reduced coping abilities. These findings highlight the importance of addressing loneliness and social isolation in patients with IBD. Doing so may be key to developing psychological interventions that improve the well-being and health of those living with IBD.

RESUMO

Methamphetamine use and HIV disproportionately affect sexual and gender minority (SGM) people assigned male at birth. Identifying risk factors for methamphetamine use is crucial to inform preventive interventions. In this cohort study with 1,296 SGM people assigned male at birth, ages 16 to 29, and who resided in Chicago, Poisson regression analyses indicated the prevalence of methamphetamine use increased from 2015 to 2023 [Incidence Rate Ratio (IRR) = 1.07; 95% CI = 1.01 to 1.13; P = 0.02]. This increase was most pronounced among those ages 25 or older at baseline (IRR = 2.20; 95% CI = 1.33 to 3.63; P = 0.002), and 23.9 [Interquartile Range (IQR) = 22.1 to 26.9] was the median age of first-time methamphetamine use. In 826 participants with a prior HIV diagnosis or previous inflammatory measurements, Cox proportional-hazards models examined risk factors for incident, first-time methamphetamine use. Adjusting for other substance use, the rate of incident, first-time methamphetamine use was two-fold greater after HIV diagnosis [adjusted hazard ratio (aHR) = 2.02; 95% CI = 1.27 to 3.23; P = 0.003]. For each SD higher C-reactive protein, the rate of incident, first-time methamphetamine use was 18% greater (aHR = 1.18; 95% CI, 1.05 to 1.34; P = 0.008). HIV seroconversion and inflammation could increase the risk of initiating methamphetamine use in SGM people assigned male at birth.

RESUMO

BACKGROUND: The syndemic of HIV, substance use (SU), and mental illness has serious implications for HIV disease progression among women. We described co-utilization of HIV care, SU treatment, and mental health treatment among women with or at risk for HIV. METHODS: We included data from women with or at risk for HIV (n = 2559) enrolled in all 10 sites of the Women's Interagency HIV Study (WIHS) from 2013 to 2020. Current SU was defined as self-reported, non-medical use of drugs in the past year, excluding use of only marijuana. Tobacco and alcohol were assessed separately. We described co-utilization of SU treatment, tobacco and alcohol use treatment, HIV care, and mental health care in the past year among women who were eligible for each service. We compared service utilization by those who did/did not utilize SU treatment using Wald Chi-square tests. RESULTS: Among women with current SU (n = 358), 42% reported utilizing SU treatment. Among those with current SU+HIV (n = 224), 84% saw their HIV provider, and 34% saw a mental health provider. Among women with current SU+heavy alcohol use (n = 95), 18% utilized alcohol use treatment; among current SU+tobacco use (n = 276), 8% utilized tobacco use treatment. Women who utilized SU treatment had higher utilization of alcohol use treatment (59% vs. 5%; P < .001) and tobacco use treatment (12% vs. 5%; P = .028). HIV care engagement was high regardless of SU treatment. CONCLUSIONS: We found high engagement in SU and HIV care, but low engagement in alcohol and tobacco use treatment. Integrated SU treatment services for women, including tobacco/alcohol treatment and harm reduction, are needed to optimize treatment engagement and HIV care continuum outcomes.

RESUMO

Sexual minority men (SMM) are disproportionately impacted by HIV and thus, HIV related-health complications. HIV has been linked to earlier onset of multi-morbid chronic diseases and declines in physical and cognitive functioning attributable to chronic HIV immune activation and resulting inflammation. Inflammation has been targeted with mindfulness-based interventions (MBIs); however, hypothesized negative associations between mindfulness and inflammation need to be confirmed in SMM with HIV. This is a secondary data analysis of baseline data from a randomized clinical trial (RCT) of SMM living with HIV with biologically confirmed recent methamphetamine use (ARTEMIS). Mindfulness was assessed with the Five Factor Mindfulness Questionnaire (FFMQ). Inflammation was assessed via cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α). Separate adjusted (for age, viral load, CD4 count, and methamphetamine use) regression models evaluated associations between four facets of mindfulness (description, awareness, non-judgement, and non-reactivity) with IL-6 and TNF-α. The average age of the participants was 43.86 (SD = 8.95). Both description (b = .54, se = .24) and awareness (b = .50, se=.23) were positively associated with IL-6. All other associations between mindfulness and inflammation were non-significant in adjusted models. There was also some evidence to suggest that engagement in care moderated associations between description and non-reactivity with IL-6 (ΔR2 = .03, F = 3.64), such that description and non-reactivity were each positively associated with inflammation among those who attended <100% of primary care appointments (b = 1.04, se=.34 and b = 1.23, se=.39, respectively), but was not associated with inflammation among those who attended 100% of appointments (b =.16, se=.32 and b=-.17, se=.40, respectively). There was also a significant interaction between 12-step program attendance and awareness with IL-6 (ΔR2= .03, F = 4.26), such that awareness was positively associated with inflammation among those who attended 12-step programming (b = 1.25, se = .41), but not associated with inflammation among those who did not (b = .22, se = .28). Further research is needed to understand how and under what circumstances mindfulness is associated with pro- versus anti-inflammatory processes.Trial Registration: NCT01926184.

RESUMO

Fifty-five of 62 women who inject drugs (WWID) selected long-acting cabotegravir (CAB-LA) over oral PrEP, and 51/55 received a first injection. More recent injection drug use and number of sexual partners were associated with selecting CAB-LA (P < .05). Findings provide preliminary evidence of a strong preference for longer-acting products among WWID.

RESUMO

BACKGROUND: Although behavioral interventions show some promise for reducing stimulant use and achieving durable viral suppression in sexual minority men (SMM) with HIV, scalable mHealth applications are needed to optimize their reach and cost-effectiveness. METHODS: Supporting Treatment Adherence for Resilience and Thriving (START) is a randomized controlled trial (RCT) testing the efficacy and cost-effectiveness of a mHealth application that integrates evidence-based positive affect regulation skills with self-monitoring of adherence and mood. The primary outcome is detectable HIV viral load (i.e., > 300 copies/mL) from self-collected dried blood spot (DBS) specimens at 6 months. Secondary outcomes include detectable DBS viral load at 12 months, self-reported stimulant use severity, anti-retroviral therapy (ART) adherence, and positive affect over 12 months. A national sample of up to 250 SMM with HIV who screen positive for stimulant use disorder and reporting suboptimal ART adherence is being recruited via social networking applications through April of 2024. After providing informed consent, participants complete a run-in period (i.e., waiting period) including two baseline assessments with self-report measures and a self-collected DBS sample. Those who complete the run-in period are randomized to either the START mHealth application or access to a website with referrals to HIV care and substance use disorder treatment resources. Participants provide DBS samples at baseline, 6, and 12 months to measure HIV viral load as well as complete self-report measures for secondary outcomes at quarterly follow-up assessments over 12 months. DISCUSSION: To date, we have paid $117,500 to advertise START on social networking applications and reached 1,970 eligible participants ($59.77 per eligible participant). Although we identified this large national sample of potentially eligible SMM with HIV who screen positive for a stimulant use disorder and report suboptimal ART adherence, only one-in-four have enrolled in the RCT. The run-in period has proven to be crucial for maintaining scientific rigor and reproducibility of this RCT, such that only half of consented participants complete the required study enrollment activities and attended a randomization visit. Taken together, findings will guide adequate resource allocation to achieve randomization targets in future mHealth research SMM with HIV who use stimulants. TRIAL REGISTRATION: This protocol was registered on clinicaltrials.gov (NCT05140876) on December 2, 2021.

RESUMO

Sexually minoritized men (SMM) with HIV who use stimulants experience difficulties achieving and maintaining an undetectable viral load (VL). Home-based VL monitoring could augment HIV care by supporting interim, early identification of detectable VL. We describe implementation challenges associated with a home-collection device for laboratory-based VL testing among SMM with HIV who use stimulants. From March-May 2022, cisgender SMM with HIV reporting moderate-to-severe stimulant use disorder and suboptimal (< 90%) past-month antiretroviral therapy (ART) adherence were recruited via a consent-to-contact participant registry. Eligible men completed teleconference-based informed consent and were mailed a HemaSpot-HD blood collection device (volume capacity 160 µL; lower limit of detection 839 copies/mL) with detailed instructions for home blood self-collection and return shipment. Implementation process measures included estimated blood volume and VL quantification. Among 24 participants, 21 (88%) returned specimens with a median duration of 23 days (range: 10-71 days) between sending devices to participants and receiving specimens. Of these, 13/21 (62%) included enough blood (≥ 40 µL) for confidence in detectable/undetectable results; 10/13 (77%) had detectable VL, with 4/10 (40%) were quantifiable at ≥ 839 copies/mL. The remaining 8/21 had low blood volume (< 40 µL), but 3/8 (38%) still had detectable VL, with 1/3 (33%) quantifiable at ≥ 839 copies/mL. Home blood collection of ≥ 40 µL using HemaSpot-HD was feasible among this high-priority population, with > 50% having a VL detected. However, interim VL monitoring using HemaSpot-HD among those experiencing difficulties with ART adherence may be strengthened by building rapport via teleconferencing and providing detailed instructions to achieve adequate sample volume.

RESUMO

Our study assessed the association between methamphetamine (i.e., crystal meth, CM) use and awareness and interest in event-driven (ED) PrEP among HIV-negative and those with unknown serostatus cisgender males and transgender people. We performed log-binomial regression analysis to predict awareness (i.e., having heard of ED PrEP) and being interested in ED PrEP. We found that participants who recently used CM were less likely to know of ED PrEP (aPR = 0.83, 95% CI [0.69, 0.99]) but more interested in ED PrEP (aPR = 1.12, 95% CI [1.01, 1.30]), after accounting for demographic and HIV-related behaviors. Opportunities to expand PrEP uptake and improve adherence among individuals who report CM use are essential to impact the HIV epidemic significantly. Continued research on the needs and best practices to work with this community is needed to ensure a successful rollout and implementation of ED PrEP.

RESUMO

Black women living with HIV (BWLWH) face barriers that impact health outcomes. However, positive psychosocial indicators may influence HIV care outcomes. Among this cross-sectional study of 119 BWLWH, a network analysis was utilized to examine relationships between positive psychosocial factors and HIV-related health outcomes. A preliminary polychoric analysis was conducted to examine correlations between the variables, and the network analyzed connections between resilience, self-efficacy, self-esteem, perceived social support, religious coping, post-traumatic growth, and an indicator variable for suboptimal HIV care outcomes (low medication adherence, detectable viral load, and missed HIV-related health visits) and determined the centrality measures within the network. Seven significant associations were found among the factors: self-efficacy and self-esteem, post-traumatic growth and resilience, post-traumatic growth and self-efficacy, post-traumatic growth and religious coping, perceived social support and resilience, self-esteem and resilience, self-esteem and perceived social support (bootstrapped 95% CI did not contain zero). Self-efficacy was the strongest indicator associated with the other factors. Although not statistically significant, the indicator for suboptimal HIV care outcomes was negatively associated with perceived social support and religious coping. Future interventions incorporating self-efficacy may be beneficial to the overall well-being of Black women.

RESUMO

BACKGROUND: Young men who have sex with men and transgender women (YMSM/TGW) have disproportionately high HIV incidence and lower preexposure prophylaxis (PrEP) adherence. Point-of-care (POC) urine tenofovir (TFV) rapid assay (UTRA) testing permits real-time monitoring for nonadherence within clinical settings. We performed UTRA testing among PrEP users to examine the relationship between low PrEP adherence and future PrEP discontinuation, and the accuracy of POC testing compared to gold-standard liquid chromatography tandem mass spectrometry (LC/MS/MS). METHODS: YMSM/TGW participants ( n  = 100) were recruited during a daily PrEP visit. Logistic regression models analyzed the relationship between the primary predictor of urine POC assay results (cutoff 1,500 ng/ml) and the primary outcome of PrEP discontinuation, defined as no PrEP follow-up or prescription within 120 days. RESULTS: Overall, 19% of participants had low urine TFV and 21% discontinued PrEP, while 11% of participants self-reported low PrEP adherence (<4 pills per week), which was only 43% sensitive/84% specific in predicting low TFV levels and was not associated with PrEP discontinuation. Low urine TFV level predicted PrEP discontinuation [adjusted odds ratio (AOR) 6.1; 95% confidence interval (CI): 1.4-11; P  = 0.005] and was 71% sensitive/90% specific for discontinuation after 120 days. Compared to LC/MS/MS, UTRA testing had a 98% positive and 100% negative predictive value. CONCLUSIONS: In a sample of YMSM/TGW on daily PrEP, POC UTRA testing predicted PrEP discontinuation more accurately than self-reported adherence, with high predictive values compared to LC/MS/MS. UTRA testing may be a clinical tool for directing preventive interventions towards those likelier to discontinue PrEP despite ongoing HIV vulnerability.

RESUMO

INTRODUCTION: Community-based cohort studies of HIV seroconversion can identify important avenues for enhancing HIV prevention efforts in the era of pre-exposure prophylaxis (PrEP). Within individuals, one can assess exposure and outcome variables repeatedly and with increased certainty regarding temporal ordering. This cohort study examined the association of several risk factors with subsequent HIV seroconversion. METHODS: We report data from a 4-year study (2017-2022) of 6059 HIV seronegative sexual and gender minority individuals who have sex with men who had indications for-, but were not using-, PrEP at enrolment. Participants completed repeat exposure assessments and self-collection of biospecimens for HIV testing. We examined the roles of race and ethnicity, socio-economic status, methamphetamine use and PrEP uptake over the course of follow-up in relation to HIV seroconversion. RESULTS: Over 4 years, 303 of the participants seroconverted across 18,421 person-years (incidence rate = 1.64 [95% CI: 1.59-1.70] per 100 person-years). In multivariable discrete-time survival analysis, factors independently associated with elevated HIV seroconversion risk included being Black/African American (adjusted risk ratio [aRR]: 2.44, 1.79-3.28), Hispanic/Latinx (1.53, 1.19-1.96), housing instability (1.58, 1.22-2.05) and past year methamphetamine use (3.82, 2.74-5.33). Conversely, time since study enrolment (24 vs. 12 months, 0.67, 0.51-0.87; 36 months, 0.60, 0.45-0.80; 48 months, 0.48, 0.35-0.66) and higher education (master's degree or higher vs. less than or equal to high school, 0.36, 0.17-0.66) were associated with reduced seroconversion risk. Compared to non-PrEP users in the past 2 years without a current clinical indication, those who started PrEP but then discontinued had higher seroconversion risk, irrespective of clinical indication (3.23, 1.74-6.46) or lack thereof (4.30, 1.85-9.88). However, those who initiated PrEP in the past year (0.14, 0.04-0.39) or persistently used PrEP in the past 2 years (0.33, 0.14-0.74) had a lower risk of seroconversion. Of all HIV seroconversions observed during follow-up assessments (12, 24, 36 and 48 months), methamphetamine was reported in the 12 months prior 128 (42.2%) times (overall). CONCLUSIONS: Interventions that acknowledge race and ethnicity, economic variables such as education and housing instability, and methamphetamine use are critically needed. Not only are interventions to engage individuals in PrEP care needed, but those that retain them, and re-engage those who may fall out of care are essential, given the exceptionally high risk of seroconversion in these groups.

RESUMO

Among sexual minority men (SMM), HIV and use of stimulants such as methamphetamine are linked with immune activation and systemic inflammation. Throughout the COVID-19 pandemic, SMM encountered financial challenges and structural obstacles that might have uniquely contributed to immune dysregulation and systemic inflammation, beyond the impacts of HIV and stimulant use. Between August 2020 and February 2022, 72 SMM with and without HIV residing in South Florida enrolled in a COVID-19 prospective cohort study. Multiple linear regression analyses examined unemployment, homelessness, and history of arrest as structural correlates of soluble markers of immune activation (i.e., sCD14 and sCD163) and inflammation (i.e., sTNF-α receptors I and II) at baseline after adjusting for HIV status, stimulant use, and recent SARS-CoV-2 infection. Enrolled participants were predominantly Latino (59%), gay-identified (85%), and with a mean age of 38 (SD, 12) years with approximately one-third (38%) of participants living with HIV. After adjusting for HIV status, SARS-CoV-2 infection, and recent stimulant use, unemployment independently predicted higher levels of sCD163 (ß = 0.24, p = 0.04) and sTNF-α receptor I (ß = 0.26, p = 0.02). Homelessness (ß = 0.25, p = 0.02) and history of arrest (ß = 0.24, p = 0.04) independently predicted higher levels of sCD14 after adjusting for HIV status, SARS-CoV-2 infection, and recent stimulant use. Independent associations exist between structural barriers and immune activation and systemic inflammation in SMM with and without HIV. Future longitudinal research should further elucidate complex bio-behavioral mechanisms linking structural factors with immune activation and inflammation.

RESUMO

OBJECTIVE: This epigenomics sub-study embedded within a randomized controlled trial examined whether an evidenced-based behavioral intervention model that decreased stimulant use altered leukocyte DNA methylation (DNAm). METHODS: Sexual minority men with HIV who use methamphetamine were randomized to a five-session positive affect intervention (n = 32) or an attention-control condition (n = 21), both delivered during three months of contingency management for stimulant abstinence. All participants exhibited sustained HIV virologic control - an HIV viral load less than 40 copies/mL at baseline and six months post-randomization. The Illumina EPIC BeadChip measured leukocyte methylation of cytosine-phosphate-guanosine (CpG) sites mapping onto five a priori candidate genes of interest (i.e., ADRB2, BDNF, FKBP5, NR3C1, OXTR). Functional DNAm pathways and soluble markers of immune dysfunction were secondary outcomes. RESULTS: Compared to the attention-control condition, the positive affect intervention significantly decreased methylation of CpG sites on genes that regulate ß2 adrenergic and oxytocin receptors. There was an inconsistent pattern for the direction of the intervention effects on methylation of CpG sites on genes for glucocorticoid receptors and brain-derived neurotrophic factor. Pathway analyses adjusting for the false discovery rate (padj < 0.05) revealed significant intervention-related alterations in DNAm of Reactome pathways corresponding to neural function as well as dopamine, glutamate, and serotonin release. Positive affect intervention effects on DNAm were accompanied by significant reductions in the self-reported frequency of stimulant use. CONCLUSIONS: There is an epigenetic signature of an evidence-based behavioral intervention model that reduced stimulant use, which will guide the identification of biomarkers for treatment responses.

RESUMO

BACKGROUND: Sexual minority men (SMM) are exposed to societal and structural stressors that translate into poor health outcomes. One such outcome is substance use, which research has long documented as a prominent disparity among SMM. Methamphetamine is a particularly deleterious substance for SMM because its use is often framed as a coping response to social and structural stressors. METHOD: Guided by stress and coping theory and a life course perspective, the purpose of this qualitative study is to assess the development of coping strategies in the context of prominent social and structural determinants among SMM living with HIV who use methamphetamine. RESULTS: Data were collected from 2016 to 2018 via in-depth interviews with 24 SMM living with HIV who use methamphetamine in San Francisco, CA. Mean age of participants was 47 and over half self-identified as ethnoracial minorities. Narrative analysis surfaced a sequential pattern of disconnection at foundational, relational, and recovery levels. This analysis revealed that multi-level stressors were present across the life course that amplified engagement in methamphetamine use. CONCLUSION: Findings highlight the benefits of holistic, integrated, and trauma-informed approaches to address the function of methamphetamine use as a response to societal, cultural, and institutional processes of stigmatization and discrimination. Peer-based approaches may also be beneficial to reframe the ways in which SMM living with HIV who use methamphetamine form and sustain relationships.

RESUMO

BACKGROUND: Important gaps exist in our understanding of loneliness and biobehavioral outcomes among sexual minority men (SMM), such as faster HIV disease progression. At the same time, SMM who use methamphetamine are approximately one-third more likely than non-users to develop cardiovascular disease. This study examined associations of loneliness, stimulant use, and cardiovascular risk in SMM with and without HIV. METHOD: Participants were enrolled from August 2020 to February 2022 in a 6-month prospective cohort study. The study leveraged self-report baseline data from 103 SMM, with a subset of 56 SMM that provided a blood sample to measure markers of cardiovascular risk. RESULTS: Loneliness showed negative bivariate associations with total cholesterol and LDL cholesterol in the cardiometabolic subsample (n = 56). SMM with methamphetamine use (t(101) = 2.03, p < .05; d = .42) and those that screened positive for a stimulant use disorder (t(101) = 2.07, p < .05; d = .46) had significantly higher mean loneliness scores. In linear regression analyses, negative associations of loneliness with LDL and total cholesterol were observed only among SMM who used methamphetamine. CONCLUSION: We observed lower cholesterol in SMM reporting loneliness and methamphetamine use. Thus, in addition to the observed associations of loneliness with cholesterol, there are important medical consequences of methamphetamine use including cardiovascular risk, higher HIV acquisition risk and progression, as well as stimulant overdose death. This cross-sectional study underscores the need for clinical research to develop and test interventions targeting loneliness among SMM with stimulant use disorders.

RESUMO

Background: Sexual minority men (SMM) with HIV who use stimulants may experience greater difficulties with antiretroviral therapy adherence which amplifies risk for unsuppressed HIV viral load (VL). Remote monitoring of VL could support efforts to rapidly respond to sub-optimal adherence. Methods: This qualitative study enrolled 24 SMM with HIV who use stimulants to examine experiences with two different dried blood spots (DBS) self-sampling devices (i.e., Tasso-M20 vs. HemaSpot HD) to measure VL. Participants were asked to complete self-sampling of DBS using both devices, and then participated in a 45-minute semi-structured interview. Interviews focused on ease of use, device preference, experiences with receiving and mailing kits, and barriers to participating in research. A thematic analysis was conducted to analyze interviews transcripts. Results: Twenty-two participants (92%) returned the Tasso-M20 and 21 (88%) returned the Hemaspot HD devices. Among the 22 participants that completed qualitative interviews, twenty-three codes were identified and collapsed within seven themes. Preferences for devices were based on convenience, pain and prior experiences with finger-pricking technology. Participants emphasized that clearer instructions with contingency plans for self-sampling of DBS would improve the user experience with self-sampling of DBS. Intersectional stigma (e.g., HIV, sexual minority status, and substance use) was noted as an important consideration in implementing self-sampling of DBS. Promoting decision making, or the option to choose sampling method based on personal preferences, may improve engagement and likelihood of DBS completion. Conclusions: Findings will guide the broader implementation of self-sampling of DBS to optimize VL monitoring in SMM with HIV who use stimulants.
