Item Acceptability of dual HIV/syphilis rapid test in community- and home-based testing strategy among transgender women in Buenos Aires, Argentina(2021-02-03) Zalazar, Virginia; Frola, Claudia; Gun, Ana; Radusky, Pablo; Panis, Natalia k; Cardozo, Nadir F; Fabian, Solange; Duarte, Mariana I; Aristegui, Ines; Cahn, Pedro; Sued, OmarBackground: Little is known of acceptability and feasibility of dual HIV and syphilis rapid tests in community- and home-based provider-initiated strategies among transgender women (TGW), in Latin America. Objectives were (1) to assess the acceptability of this strategy and, (2) to determine the percentage of positive results of HIV and syphilis, analyze the correlates of HIV or syphilis positive results, and measure the rates of effective referral and treatment completion among TGW. Methods: A multidisciplinary team tested 89 TGW in Buenos Aires. An acceptability survey was administered after the HIV/syphilis Duo test was used. All confirmed cases were referred for treatment initiation. Results: We found high levels of acceptability (98.8%) of this strategy among TGW. However, only 60.7% preferred simultaneous HIV and syphilis diagnosis test. Moreover, we found 9% of positive results of HIV, 51.7% of syphilis, and 3.4% of positive results for both infections. Only not being tested before was associated with an HIV positive result, and only low level of education was associated with a positive syphilis result. Among 8 TGW who tested positive for HIV, 37.5% (n = 3) started antiretroviral therapy. Of 46 who tested positive for syphilis, only 73.9% (n = 34) were effectively referred and from 23 who started treatment, only 39.1% completed it. Conclusions: Community- and home-based dual HIV and syphilis rapid test is a feasible and highly acceptable approach for this hard-to-reach population. Implementing similar strategies could improve screening uptake and accessibility. However, these results highlight the need to improve strategies for treatment uptake, in order to reduce morbidity and risk of onward transmission.Item Correlates of depressive symptoms in transgender women initiating HIV treatment in Argentina(Wolters Kluwer Health, 2022) Aristegui, Ines; Radusky, Pablo; Zalazar, Virginia; Cardozo, Nadir; Fabian, Solange; Duarte, Mariana; Frola, Claudia; Cahn, Pedro; Sued, OmarObjective: To assess efficacy and safety of dolutegravir (DTG) + lamivudine (3TC) vs. DTG + tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) in treatment-naive adults with HIV-1 in the prespecified 144-week secondary analyses of GEMINI-1 and GEMINI-2. Design: Identical, multicenter, phase III, randomized, non-inferiority studies (double-blind through 96 weeks). Methods: Participants with HIV-1 RNA ≤500 000 copies/ml and no major viral resistance mutations to nucleoside reverse transcriptase inhibitors, nonnucleoside reverse transcriptase inhibitors, or protease inhibitors were randomized 1:1 to once-daily DTG + 3TC or DTG + TDF/FTC. Results: At week 144, DTG + 3TC (N = 716) was noninferior to DTG + TDF/FTC (N = 717) in proportion of participants achieving HIV-1 RNA <50 copies/ml (Snapshot algorithm) in the pooled analysis (82% vs. 84%, respectively; adjusted treatment difference [95% confidence interval (CI)], −1.8% [−5.8, 2.1]), GEMINI-1 (−3.6% [−9.4, 2.1]), and GEMINI-2 (0.0% [−5.3, 5.3]). Twelve DTG + 3TC participants and nine DTG + TDF/FTC participants met protocol-defined confirmed virologic withdrawal (CVW) criteria; none developed treatment-emergent resistance. One DTG + 3TC participant who did not meet CVW criteria developed M184V at week 132 and R263R/K at week 144, conferring a 1.8-fold change in susceptibility to DTG; non-adherence to therapy was reported. Significantly fewer drug-related adverse events occurred with DTG + 3TC vs. DTG + TDF/FTC (20% vs. 27%; relative risk [95% CI], 0.76 [0.63–0.92]). Renal and bone biomarker changes favored DTG + 3TC. Conclusions: Three-year durable efficacy, long-term tolerability, and high barrier to resistance support first-line use of DTG + 3TC for HIV-1 treatment (see Supplemental Digital Content 1, https://links.lww.com/QAD/C297; video abstract).Item Factores contextuales, sociales e individuales como barreras y facilitadores para el acceso a la salud de mujeres trans: desde la perspectiva de la comunidad(2018-12) Zalazar, Virginia; Aristegui, Ines; Cardozo, Nadir; Sued, Omar; Rodríguez, Allan E.; Frola, Claudia; Pérez, HéctorBackground: Transgender women (TGW) are vulnerable to several health problems, including HIV and other STDs, which significantly reduces their life expectancy. Therefore, there is an urgent need to understand factors affecting access to healthcare. Methods: A qualitative study was conducted among TGW living in rooming houses (TRH) in Buenos Aires. The objective of the study was to explore contextual, social and individual barriers and facilitators to access healthcare, particularly HIV services, and the acceptability of interventions. Two focus groups and five interviews were conducted in three TRH. Results: Contextual barriers described were the limited number of appointments and long waiting hours. Social obstacles included health workers’ stigma and discrimination and blaming of TGW for their health burdens, as well as HIV stigma within TGW groups. Most important facilitator were inclusive services. Individual barriers were self-exclusion and anticipated stigma, resulting in high rates of self-medication and industrial silicone injection. Peers play an important role by accompanying others TGW to healthcare. While reporting similar problems, TGW recommended different interventions according to their THR profile. Conclusions: As the stigma and discrimination is the most important barrier, it is imperative to ensure awareness of transgender issues for all personnel of healthcare services. It is necessary to implement a wide range of strategies in health facilities, and evaluate the community acceptance of domiciliary interventions, in order to respond to the different demands of this population.Item Home-based HIV testing: Using different strategies among transgender women in Argentina(2020-03-19) Frola, Claudia; Zalazar, Virginia; Cardozo, Nadir; Vázquez, María L. VázquezBackground In Argentina, HIV prevalence among transgender women (TGW) has been reported at 34%. The stigma is one of the most important factors limiting their access to healthcare services. The aims of this study were to compare different HIV testing methodologies, to determine the factors associated with HIV diagnosis and to determine the feasibility of a home-based HIV testing service for TGW. Methods A multidisciplinary team performed home-based HIV testing interventions in four cities of Argentina. Participants self-identified as TGW, older than 14 years and with a negative or unknown HIV status. Blood samples were screened by two rapid tests (RT), one based on antibodies (Determine™ HIV-1/2) and the other on antigen and antibodies (Determine™ HIV-1/2 Combo), and the subsequent blood processing via 4th generation ELISA (VIDAS HIV DUO). All reactive samples were confirmed with a viral load (VL). We compared the results of both RT with the ELISA. Samples were pooled in groups of 6 and a VL (Abbott Real Time) performed to identify acute HIV infections. Factors associated with HIV infection were evaluated with multivariate logistic regression analysis. Results A total of 260 TGW were tested, 51 tested positive (HIV prevalence 19.6%). There were no discordant results between both RTs nor between RTs and 4th generation ELISA, therefore the correlation was 100%. The VL identified 2 additional positive samples. The final analytic sample for positive cases consisted of 53 TGW. In the multivariate analysis, factors associated with a positive HIV result were history of other sexually transmitted infections (STIs) and not being previously tested for HIV. TGW tested for the first time were at 4 times greater risk of being HIV positive compared to those that were tested previously. Conclusions A multidisciplinary home-based HIV testing service among TGW is feasible and effective to detect cases of HIV infection. The testing algorithm should start with an RT followed by molecular diagnosis. The history of STIs and never having been tested for HIV were the factors associated with HIV-positive results and should determine efforts to reach this population. Home-based testing reaches individuals that were not tested before and who have more risk of acquiring HIV.Item Prevalence and correlates of current cigarette smoking among transgender women in Argentina(University of Texas MD Anderson Cancer Center, United States, 2023-12) Cartujano-Barrera, Francisco; Mejia, Raul M.; Radusky, Pablo; Cardozo, Nadir; Duarte, Mariana; Fabian, Solange; Caballero, Romina; Zalazar, Virginia; Ramos-Pibernus, Alixida; Alpert, Ash B.; Cupertino, Ana Paula; Frola, Claudia; Aristegui, InesObjective: To assess the prevalence of current cigarette smoking among transgender women in Argentina, and to examine the unique associations of current cigarette smoking with demographic and psychosocial factors. Methods: This study is a secondary data analysis of the TransCITAR – a prospective cohort study of transgender individuals living in Buenos Aires, Argentina – baseline data. The baseline survey collected information on sociodemographic characteristics, perceived health status, depressive symptoms, suicide attempts, current cigarette smoking, alcohol use disorder, and substance use. Participants were also asked about lifetime experiences of physical and sexual violence perpetrated by partners, clients and/or the police, and experiences of gender identity stigma in the past year from healthcare workers and the police. Lastly, participants were asked if they had ever been arrested. Fisher’s exact test was used to compare proportions in categorical variables and student t-test was used for continuous variables. Significant associations with current cigarette smoking were tested in a logistic regression model adjusted for all significant associations. Results: A total of 41.7% of participants (n = 393) reported current cigarette smoking. Compared to their non-smoking counterparts, participants who reported current cigarette smoking (1) had completed less education, (2) were more likely to be born in Argentina, (3) more likely to had migrated to Buenos Aires from other parts of the country, (4) more likely to report a history of sex work, (5) more likely to perceive their health as excellent, (6) more likely to screen positive for hazardous alcohol drinking, (7) more likely to report any substance and cocaine use in the past year, (8) more likely to experience gender identity stigma from the police in the past year, and (9) more likely to being arrested in their lifetime (all p’s < 0.05). After controlling for all significant associations, education level of less than high school (AOR = 1.79, 95% CI 1.02–2.12), hazardous drinking (AOR = 2.65, 95% CI 1.30–5.37), and any substance use in the last year (AOR = 2.14, 95% CI 1.16–3.94) were positively and independently associated with current cigarette smoking. Conclusion: Among transgender women in Argentina, current cigarette smoking was more than double the rate for cisgender women. Current cigarette smoking was associated with education, hazardous drinking, and any drug use. These results will inform future smoking cessation interventions among transgender women in Argentina.Item Prevalence of cryptococcal infection among advanced HIV patients in Argentina using lateral flow immunoassay(2017-06-15) Frola, Claudia; Guelfand, Liliana; Blugerman, Gabriela; Szyld, Edgardo; Kaufman, Sara; Cahn, Pedro; Sued, Omar; Pérez, HéctorBackground Globally, Latin America ranks third among regions with most cases of AIDS related cryptococcal meningitis. In 2009, a lateral flow immunoassay (LFA) for the detection of cryptococcal antigen (CrAg) was developed as a potential point-of-care test for diagnosis of cryptococcal infection. In 2011 World Health Organizations recommended on CrAg screening for HIV positive persons with CD4 below 100 cells/μL, followed by preemptive fluconazole treatment. However, in Argentina no formal recommendations for CrAg screening have been issued. Methods HIV positive patients > = 18 years with advanced immunosuppression (CD4 counts ≤100 cells/μL within 3 months or WHO stage III/IV), who visited the hospital between April 1, 2014 and January 31, 2015, were included. The LFA was performed according to the manufacturer’s instructions on all serum samples. When CrAg detection was positive, a lumbar puncture was performed to rule out cryptococcal meningitis. Patients without evidence of meningeal involvement were treated with preemptive oral fluconazole in ambulatory care. Results We included 123 patients. Prevalence of CrAg-positivity was 8.1%. Among the 10 CrAg-positive patients, 6 had meningeal involvement detected through the CSF analysis (CSF India-ink testing, CSF CrAg and culture). The remaining 4 patients with positive CrAg received targeted preemptive treatment with oral fluconazole and were free of cryptococcal disease during the follow-up period. None of the 113 patients with a negative CrAg test result developed cryptococcal disease. Conclusions This is the first study in Argentina, to our knowledge, describing the prevalence of cryptococcosis and usefulness of CrAg screening. LFA provided early diagnosis to determine a high prevalence of CrAg in our hospital, and that screening for subclinical infection with preemptive antifungal treatment, prevented a substantial proportion of meningeal disease.Item Reduction of Gender Identity Stigma and Improvements in Mental Health Among Transgender Women Initiating HIV Treatment in a Trans-Sensitive Clinic in Argentina(2020-12) Radusky, Pablo; Zalazar, Virginia; Cardozo, Nadir; Fabian, Solange; Duarte, Mariana; Frola, Claudia; Cahn, Pedro; Sued, Omar; Aristegui, InesPurpose: Stigma toward transgender women (TGW) increases psychosocial vulnerability, leading to poor mental health and affecting access and retention in HIV care. Trans-sensitive health care (TSHC) has the potential to mitigate this adverse impact. This study aimed to describe baseline characteristics in gender identity stigma (GIS), mental health, and substance use among TGW living with HIV initiating antiretroviral treatment and to analyze changes after 6 months in HIV care in a TSHC clinic in Argentina. Methods: Sixty-one TGW living with HIV responded to the following questionnaires at baseline and after 6 months in TSHC: sociodemographic, experiences of GIS (in health care, police, etc.), Center for Epidemiologic Studies Depression Scale (CES-D) (depression), State Trait Anxiety Inventory (STAI) (anxiety), Drug Abuse Screening Test (DAST-10) (drug use), Alcohol Use Disorders Identification Test (AUDIT) (alcohol use), 8-item Personal Wellbeing Index-Adults (PWI-A) (quality of life [QOL]), Personality Inventory for DSM-5-Brief Form (PID-5-BF) (maladaptive personality traits), and Duke Index (social support). Analyses included Pearson correlations to analyze associations between variables; and paired sample t-tests, to explore changes between baseline and 6 months. Results: A significant proportion experienced episodes of GIS the last year in any context. At baseline, 50.8% showed significant depressive symptoms and 65.6% reported any drug use in the last year. At 6 months, participants experienced a significant reduction of GIS, both enacted and internalized, anxiety, drug, and alcohol use, and improvement in QOL. The remaining mental health indicators were not significantly modified. Conclusion: A TSHC service may have a gender-affirmative impact on TGW initiating HIV care that contributes to reduce GIS and substance use and improve mental health. This highlights the importance that HIV care programs for TGW comply with trans-sensitive essential components to enhance retention.Item Retention among transgender women treated with dolutegravir associated with tenofovir/ lamivudine or emtricitabine in Argentina: TransViiV study(Plos, 2023-01) Frola, Claudia; Aristegui, Ines; Figueroa, María I.; Radusky, Pablo; Cardozo, Nadir; Zalazar, Virginia; Cesar, Carina; Patterson, Patricia; Fink, Valeria; Gun, Ana; Cahn, Pedro; Sued, OmarIn Argentina, transgender women (TGW) have a high HIV prevalence (34%). However, this population shows lower levels of adherence, retention in HIV care and viral suppression than cisgender patients. The World Health Organization (WHO) recommends the transition to dolutegravir (DTG)-based regimens to reduce adverse events and improve adherence and retention. The purpose of this study was to determine retention, adherence and viral suppression in naïve TGW starting a DTG-based first-line antiretroviral treatment (ART) and to identify clinical and psychosocial factors associated with retention. We designed a prospective, open-label, single-arm trial among ART-naïve HIV positive TGW (Clinical Trial Number: NCT03033836). Participants were followed at weeks 4, 8, 12, 24, 36 and 48, in a trans-affirmative HIV care service that included peer navigators, between December, 2015 and May, 2019. Retention was defined as the proportion of TGW retained at week 48 and adherence was self-reported. Viral suppression at <50 copies/mL was evaluated using snapshot algorithm and as per protocol analysis. Of 75 TGW screened, 61 were enrolled. At baseline, median age was 28 y/o., HIV-1-RNA (pVL) 46,908 copies/mL and CD4+ T-cell count 383 cells/mm3. At week 48, 77% were retained and 72% had viral suppression (97% per protocol). The regimen was well tolerated and participants reported high adherence (about 95%). Eleven of the fourteen TGW who discontinued or were lost to follow-up had undetectable pVL at their last visit. Older age was associated with better retention. DTG-based treatment delivered by a trans-competent team in a trans-affirmative service was safe and well tolerated by TGW and associated with high retention, high adherence and high viral suppression at 48 weeks among those being retained.Item The Impact of Gender Identity Stigma and Mental Health on HIV Treatment Among Transgender Women in Argentina(Springer Publishing Company, 2022) Radusky, Pablo; Aristegui, Ines; Mandell, Lissa N.; Dell’Isola, Emanuel; Zalazar, Virginia; Cardozo, Nadir; Frola, Claudia; Jones, Deborah L.; Sued, OmarIn Argentina, HIV prevalence in transgender women (TGW) is high while engagement in HIV treatment is low due to multiple factors: gender identity stigma (GIS), mental health problems (e.g., depressive symptoms) and substance use. This study examined the impact of these factors on HIV treatment uptake among TGW in Argentina. A sample of 79 TGW “on” and “off” treatment completed questionnaires to assess GIS, depressive symptoms (CES-D), alcohol (AUDIT) and drug use (DAST-10), suicidal ideation, HIV-related stigma (HIV Stigma Scale) and support from family. From them, 36.7% met criteria for “off” HIV treatment; 49.4%, for significant depressive symptoms; 53.2%, for hazardous alcohol use; and 29.7%, for problems related to drug use. GIS was positively associated with depressive symptoms and HIV-related stigma, both in TGW “on” and “off” treatment, and with alcohol and drug use, only in the last group. In the multivariable model, only experiences of GIS from the police were negatively associated with being “on” treatment, whereas GIS in workplaces (excluding sex work venues) were associated with increased odds of being “on” treatment. GIS, specifically from the police, has a far-reaching impact on the physical and emotional health of TGW living with HIV in Argentina, as it is associated with negative mental health indicators, substance use and suboptimal HIV care uptake.
