RESUMEN

The development of effective HIV cure strategies is crucial. However, most research in this area has been concentrated in high-income countries, underscoring the need to expand efforts to regions like Latin America and the Caribbean (LAC), which face distinct biomedical, social, political, and economic challenges. Data on LAC's participation in HIV cure research, along with stakeholder perceptions, reveal that the work being done in the region is scarce, fragmented, scattered, and characterized by limited resources and infrastructure. Establishing a regional consortium of basic researchers, clinicians, social scientists, and community members in LAC could be a key step in integrating the region into the global HIV cure landscape. We have already begun laying the groundwork for its creation and propose to name it 'LAC-Cura'-short for 'Latin America and the Caribbean HIV Cure Consortium'.

RESUMEN

INTRODUCCIÓN: Existe controversia con respecto a los factores que determinan un mayor riesgo de gravedad y complicaciones por COVID-19 en personas que viven con VIH (PVVIH). Asimismo, hay datos limitados sobre el impacto de la vacunación contra SARS-CoV-2 en la hospitalización en esta población. OBJETIVOS: Describir las características clínicas y evolutivas de COVID-19 en PVVIH; Evaluar factores de riesgo para hospitalización; Evaluar el impacto de la vacunación en la hospitalización. Pacientes y MÉTODOS: Estudio observacional, prospectivo, multicéntrico (septiembre de 2020 a junio de 2022). Se registraron variables clínicas, inmunovirológicas, tratamiento antirretroviral (TARV), vacunación contra SARS-CoV-2 y hospitalización en PVVIH con COVID-19. Se realizaron análisis uni y multivariados examinando factores asociados a hospitalización utilizando dos modelos: primer modelo (sin vacunación) y segundo modelo (vacunación, mínimo una dosis). RESULTADOS: Se incluyeron 1.201 PVVIH. La mediana de edad fue 45 años. El 65,3% fueron hombres; el 38,7% presentó comorbilidades. Recibía TARV el 92,8% y presentó carga viral (CV) indetectable el 83,1%. La mediana de linfocitos T CD4+ fue de 600 céls/mm3. El 95,7% presentó síntomas. Las tasas de hospitalización, ingreso a UCI, requerimiento de oxígeno y muerte fueron 17,8%, 2,8%, 10,7% y 1,39%, respectivamente. De acuerdo con el análisis multivariado para el primer modelo, la edad > 60 años y las comorbilidades se asociaron a mayor riesgo de hospitalización, mientras que el sexo femenino y un recuento de linfocitos T CD4+ > 500 céls/mm3 tuvieron un efecto protector. En el segundo modelo sólo las comorbilidades se relacionaron con un mayor riesgo de hospitalización mientras que la vacunación y células CD4+ > 500 céls/mm3 la redujeron. CONCLUSIONES: En PVVIH las comorbilidades se asociaron con mayor tasa de hospitalización, mientras que tener linfocitos T CD4+ elevados y estar vacunado tuvieron un efecto protector. El TARV y la CV no tuvieron impacto en modelo alguno mientras que la edad y el sexo solo influyeron cuando no se consideró la vacunación.


BACKGROUND: There is controversy regarding the factors that determine a greater risk of severity and complications from COVID-19 in people living with HIV (PLHIV). Likewise, there are limited data on the impact of SARS-CoV-2 vaccination on hospitalization in this population. AIMS: To describe clinical characteristics and outcome of COVID-19 in PLHIV; To assess risk factors for hospitalization; To evaluate the impact of vaccination on hospitalization. METHODS: Multicenter, prospective, observational study (September 2020 to June 2022). Clinical and immunovirological variables, antiretroviral treatment (ART), SARS-CoV-2 vaccination, and hospitalization in PLHIV with COVID-19 were recorded. Univariate and multivariate analyzes were performed examining factors associated with hospitalization using two models: first model (without vaccination) and second model (vaccination, minimum one dose). RESULTS: 1,201 PLHIV were included. The median age was 45 years. 65.3% were men; 38.7% presented comorbidities. 92.8% received ART and 83.1% presented undetectable viral load (VL). The median CD4+ T-cell count was 600/mm3. 95.7% presented symptoms. The rates of hospitalization, ICU admission, oxygen requirement, and death were 17.8 %, 2.8%, 10.7% and 1.39%, respectively. According to the multivariate analysis for the first model, age > 60 years and comorbidities were associated with a higher risk of hospitalization, while female sex and CD4+ > 500/mm3 had a protective effect. In the second model, only the comorbidities were associated with a higher risk of hospitalization, while vaccination and CD4+ > 500/mm3 reduced it. CONCLUSIONS: in PLHIV, comorbidities were associated with a higher hospitalization rate, while having elevated CD4+ T-cell counts and being vaccinated had a protective effect. ART and VL had no impact in any model, while age and sex only had an influence when vaccination was not considered.

RESUMEN

Tenofovir has been hypothesized to be effective against COVID-19 and is available as two prodrugs, tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF), both part of antiretroviral therapy (ART) regimens. People living with human immunodeficiency virus (PLWH) might be at higher risk for COVID-19 progression; however, information about the impact of tenofovir on COVID-19 clinical outcomes remains controversial. The COVIDARE is a prospective observational multicentric study in Argentina. PLWH with COVID-19 were enrolled from September 2020 to mid-June 2022. Patients were stratified according to baseline ART into those with tenofovir (TDF or TAF) and those without. Univariate and multivariate analyses were performed to evaluate the impact of tenofovir vs. non-tenofovir-containing regimens on major clinical outcomes. Of the 1155 subjects evaluated, 927 (80%) received tenofovir-based ART (79% TDF, 21% TAF) whilst the remaining population was under non-tenofovir regimens. The non-tenofovir group had older age and a higher prevalence of heart and kidney disease. Regarding the prevalence of symptomatic COVID-19, tomographic findings, hospitalization, and mortality, no differences were observed. The oxygen therapy requirement was higher in the non-tenofovir group. In the multivariate analyses, a first model with adjustment for viral load, CD4 T-cell count, and overall comorbidities showed that oxygen requirement was associated with non-tenofovir ART. In a second model with adjustment by chronic kidney disease, tenofovir exposure was not statistically significant.

RESUMEN

OBJECTIVE: This study describes adverse events following immunization (AEFIs) and the development of SARS-COV-2 antibodies after Sputnik V, AstraZeneca, and Sinopharm COVID-19 vaccination in people with HIV (PWH). METHODS: In total, 595 adult PWH at an HIV center in Argentina from March to December 2021 were enrolled. Analysis included participants who received COVID-19 vaccination with Sputnik V, AstraZeneca, and Sinopharm, and did not receive mRNA COVID-19 vaccines. Clinical data, and local or systemic AEFI variables were collected using an online questionnaire after the first dose. Detection of S1-RBD IgG antibodies was performed between days 28 and 60 after the second dose in a subsample (SARS-CoV-2 IgG chemiluminescent immunoassay; Siemens). A multivariable logistic regression and spearman test were used for analyses. RESULTS: Mean age was 46.1 years (SD = 11.8); 70.4% were men; and median CD4 + T cells count was 659 (500-852) cells/µl. AEFIs were reported in 214 (36.0%) participants. More participants reported AEFIs after Sputnik V (29.4%) and AstraZeneca (47.5%) than Sinopharm (13.9%) (χ 2  = 35.85, P  < 0.001). Higher odds of reporting an AEFIs were associated with receiving Sputnik V [aOR = 2.90; 95% confidence interval (95% CI) = 1.40-6.04; P  = 0.004] and AstraZeneca (aOR = 5.38; 95% CI = 2.63-11.01; P  < 0.001) compared with Sinopharm. Lower odds were associated with age (aOR = 0.97; 95% CI = 0.95-0.99; P  < 0.001). Overall, 76 (95.0%) individuals assessed for the presence of SARS-CoV-2 antibody reached S1-RBD IgG antibody titers at least 1 U/ml; mean titer was 51.3 (SD = 51.07) U/ml. Higher antibody titers correlated with higher CD4 + T cells count (Rho = 0.280; P  = 0.012). CONCLUSION: NonmRNA vaccines showed a good safety profile and adequate SARS-CoV-2 antibody responses among PWH suggesting adequate protection to SARS-CoV-2.

RESUMEN

Background: Patients disengaged from HIV care, e.g., missed medication pick-ups, not attending physician visits, account for ≥70% of new HIV infections. Re-engaging and sustaining engagement is essential to controlling the HIV pandemic. This study tested a physician-delivered evidence-based intervention, Motivational Interviewing (MI), to improve health outcomes, adherence to antiretroviral therapy (ART), HIV virologic suppression, CD4+ count, retention in HIV care, and self-efficacy among patients disengaged from care in Argentina. Methods: Regional clinics (n = 6) were randomised to condition, MI Intervention or Enhanced Standard of Care (ESOC), and recruited N = 360 patients disengaged from HIV care. ART adherence, HIV RNA viral load, CD4+ count retention, and self-efficacy were assessed at baseline, 6, 12, 18, and 24-months. Indirect effects from condition to main outcomes were examined using patient-provider relationship as a mediator. The study was a cluster-randomised clinical trial entitled Conexiones y Opciones Positivas en la Argentina 2 (COPA2) and was registered at clinicaltrials.gov, NCT02846350. Findings: Participants were an average age of 39·15 (SD = 10·96), 51% were women; intervention participants were older (p = ·019), and more ESOC participants were women (60% vs. 42%, p = 0·001). Using mixed models, the intervention had no effect on ART adherence over time by condition on HIV RNA viral load, CD4+ count retention, or self-efficacy. However, analysing mediated paths, there was an indirect effect of condition on ART adherence (B = 0·188, p = 0·009), HIV viral load (B = -0·095, P = 0·027), and self-efficacy (B = 0·063, P = 0·001), suggesting the intervention was associated with improved patient-provider relationships, which was in turn associated with increased ART adherence, lower HIV viral load, and higher self-efficacy. Interpretation: These findings suggest that physician-delivered MI may enhance the patient-provider relationship, self-efficacy, and ART adherence, and reduced HIV viral load in patients disengaged from HIV care. However, these findings are preliminary due to the small number of clusters randomised, and replication is warranted. Funding: National Institutes of Health.

RESUMEN

BACKGROUND: The spread of SARS-CoV-2 required widespread lockdown to mitigate the pandemic. Argentine authorities imposed preventive social isolation for 234 days (March 20th to November 9th 2020). This measure led to major changes in the population's lifestyle. AIM: To examine the influence of COVID-19 lockdown measures on the metabolic profile of HIV-infected patients in Argentina. METHODS: Retrospective cohort study of 10,239 HIV-infected patients under follow up in a private clinic for HIV care. Adult patients with ongoing antiretroviral therapy (ART) and a baseline determination of blood glucose, total cholesterol, HDL-cholesterol and triglycerides done before lockdown (BL: second semester of 2019) and a second determination during lockdown (DL: May 2020) were included. Patients with recent changes in ART that may have metabolic impact, those starting lipid/glucose lowering agents and pregnant women were excluded. Categorical variables were compared using the χ2 test or Fisher's exact test, and continuous variables using the t-test or the Mann-Whitney test. A two-tailed value of p < 0.05 was considered significant. RESULTS: 540 individuals were included, median of age was 47 years and 74.6% were male. Median body mass index was 26.1 and 94.6% had low cardiovascular risk. There was a significant increase in the percentage of patients that met criteria for hyperglycemia (BL 4.8% and DL 8.5%, p < 0.001). We also observed significant (p < 0.001) increase in median (IQR) BL vs DL values in LDL-cholesterol [109 (90-128) vs 118 (97-139) mg/dL]; and triglycerides [120 (87-172) vs. 132 mg/dL (96-184)]. The proportion of patients with hyper-LDL cholesterolemia according to individual cardiovascular risk increased from 12.6 to 17.2% (p = 0.04). CONCLUSION: Our results suggest that quarantine, at least in its initial phases, may have a negative impact on the metabolic profile of this population.

RESUMEN

INTRODUCCIÓN: Para mitigar la propagación del SARS-CoV-2 se requirió de un confinamiento generalizado. Las autoridades argentinas impusieron aislamiento social preventivo durante 234 días (20 de marzo al 9 de noviembre de 2020), modificando el estilo de vida de la población. OBJETIVOS: Examinar la influencia de las medidas de bloqueo en el perfil metabólico de pacientes infectados por VIH en Argentina. PACIENTES Y MÉTODOS: Estudio de cohorte retrospectivo de 10.239 pacientes en seguimiento en una clínica de atención privada de personas con infección por VIH. Se incluyeron pacientes adultos con terapia antirretroviral (TARV) en curso que tuvieran una determinación de glucemia, colesterol total, colesterol HDL y trigliceridemia antes de la cuarentena (Pre-C: segundo semestre 2019) y una segunda determinación durante la misma (Intra-C: mayo 2020). Se excluyeron los pacientes con cambios en la TARV con impacto metabólico, los que iniciaron o suspendieron hipolipemiantes o hipoglucemiantes y mujeres embarazadas. Las variables categóricas se compararon mediante la prueba de la χ2 o la prueba exacta de Fisher y las continuas mediante la prueba t o la prueba de Mann-Whitney según correspondiera. Se consideró significativo un valor de p a dos colas < 0,05. RESULTADOS: Se incluyeron 540 individuos. La mediana de edad fue de 47 años y 74,6% fueron de sexo masculino. La mediana de índice de masa corporal fue 26,1 y 94,6% tenían bajo riesgo cardiovascular. Hubo un aumento significativo en el porcentaje de pacientes con hiperglucemia (Pre-C 5,2% vs Intra-C 8,5%, p 0,04), hipertrigliceridemia (Pre-C 33,9% vs Intra-C 40,7%, p 0,02) e hipercolesterolemia LDL (Pre-C 12,6% vs Intra-C 17,2%, p 0,04). CONCLUSIÓN: Nuestros resultados sugieren que la cuarentena, al menos en sus fases iniciales, puede tener un impacto negativo en el perfil metabólico de esta población.

RESUMEN

OBJECTIVES: The aim of this study was to understand how demographic and treatment-related factors impact responses to fostemsavir-based regimens. DESIGN: BRIGHTE is an ongoing phase 3 study evaluating twice-daily fostemsavir 600 mg and optimized background therapy (OBT) in heavily treatment-experienced individuals failing antiretroviral therapy with limited treatment options (Randomized Cohort 1-2 and Nonrandomized Cohort 0 fully active antiretroviral classes). METHODS: Virologic response rates (HIV-1 RNA <40 copies/ml, Snapshot analysis) and CD4+ T-cell count increases in the Randomized Cohort were analysed by prespecified baseline characteristics (age, race, sex, region, HIV-1 RNA, CD4+ T-cell count) and viral susceptibility to OBT. Safety results were analysed by baseline characteristics for combined cohorts (post hoc). RESULTS: In the Randomized Cohort, virologic response rates increased between Weeks 24 and 96 across most subgroups. Virologic response rates over time were most clearly associated with overall susceptibility scores for new OBT agents (OSS-new). CD4+ T-cell count increases were comparable across subgroups. Participants with baseline CD4+ T-cell counts less than 20 cells/µl had a mean increase of 240 cells/µl. In the safety population, more participants with baseline CD4+ T-cell counts less than 20 vs. at least 200 cells/µl had grade 3/4 adverse events [53/107 (50%) vs. 24/96 (25%)], serious adverse events [58/107 (54%) vs. 25/96 (26%)] and deaths [16/107 (15%) vs. 2/96 (2%)]. There were no safety differences by other subgroups. CONCLUSION: Week 96 results for BRIGHTE demonstrate comparable rates of virologic and immunologic response (Randomized Cohort) and safety (combined cohorts) across subgroups. OSS-new is an important consideration when constructing optimized antiretroviral regimens for heavily treatment-experienced individuals with limited remaining treatment options.

RESUMEN

The COVID-19 pandemic poses a risk to mental health and may disproportionately affect people living with HIV (PLWH). This study examined the interaction of social support and resilient coping in predicting depressive symptoms among PLWH. PLWH residing in Buenos Aires, Argentina and in Miami, Florida (US) were asked to complete an anonymous survey on the impact of COVID-19. Statistical analysis included ordinary least squares regression. A total of 1,554 participants were included. Mean age was 47.30 years; 63.70% were men. A test of three-way interaction of social support × resilient coping × study site indicated differences by site (b = -0.63, p = 0.04, 95%CI [-1.24, -0.02]). In Argentina, higher levels of social support and resilient coping were associated with lower depressive symptoms. Lower levels of social support and resilient coping were associated with higher depressive symptoms. The impact of COVID-19 on mental health illustrates the need for developing innovative strategies to support resilience and to enhance coping with stress and adversity among PLWH.


RESUMEN: La pandemia de COVID-19 presenta riesgos importantes para la salud mental y puede afectar desproporcionadamente a personas con VIH. Este estudio examinó el efecto entre el apoyo social y la resiliencia para afrontar situaciones difíciles en predecir síntomas depresivos en personas con VIH. Personas con VIH residentes de Buenos Aires (Argentina) y Miami, Florida (EE.UU) completaron una encuesta anónima sobre el impacto del COVID-19. El análisis estadístico incluyó un modelo clásico de regresión lineal con mínimos cuadrados ordinarios. Se incluyeron 1554 participantes. La edad promedio fue 47.30 años y 63.7% eran hombres. La prueba de interacción de apoyo social × resiliencia para hacer frente a situaciones difíciles × país indicó diferencias entre países (b = −0.63, p = 0.043, IC 95% [1.24, −0.02]). En Argentina, los participantes con mayor apoyo social y resiliencia para hacer frente a situaciones difíciles mostraron síntomas depresivos más bajos; y aquellos con menor apoyo social y resiliencia para hacer frente a situaciones difíciles, mostraron síntomas depresivos más altos. Este efecto no se observó en los participantes de Miami. El impacto de COVID-19 en la salud mental en personas con VIH ilustra la necesidad de desarrollar estrategias innovadoras para apoyar la resiliencia y mejorar el enfrentamiento del estrés y la adversidad.

RESUMEN

BACKGROUND: Possible human immunodeficiency virus (HIV)-1 clearance has rarely been reported. In this study, we describe a unique case of an HIV-positive, combination antiretroviral therapy (cART)-experienced woman with prior acquired immunodeficiency syndrome (AIDS) who has not experienced viral rebound for over 12 years since discontinuing cART. METHODS: Leukapheresis, colonoscopy, and lymph node excision were performed for detailed examination of virologic (including HIV reservoir) and immunologic features. Comparisons were made with chronically infected patients and healthy controls. RESULTS: No HIV-specific antibodies were detected in serum. Plasma HIV ribonucleic acid (RNA) levels were <0.2 copies/mL, and, except for low-frequency HIV deoxyribonucleic acid (DNA)+ cells in lymph node tissue (1 copy/3 × 106 cells), HIV antigen could not be detected by quantitative virus outgrowth (<0.0025 infectious units/106 CD4+ T cells) or by most measurements of HIV RNA or DNA in blood, lymph node, or gut-associated mononuclear cells. Human immunodeficiency virus-specific T-cell responses were detectable but low. Brain imaging revealed a prior biopsy site and persistent white matter disease since 1996. Human immunodeficiency virus DNA+ cells in the 1996 brain biopsy specimen confirmed her identity and initial HIV diagnosis. CONCLUSIONS: This represents the first report of complete seroreversion, prolonged posttreatment virus suppression, a profoundly small HIV reservoir, and persistent HIV-specific T cells in an adult with prior AIDS.

RESUMEN

BACKGROUND: Cumulative burden of multiple mental health conditions may worsen physical health outcomes in vulnerable populations. Accordingly, identifying cumulative burdens of mental health conditions that may affect HIV treatment and care can guide public health strategies to reduce their impact on HIV-related health outcomes. This study examined the relationship between the cumulative burden of mental health conditions and factors associated with engagement in HIV care in Argentina. METHOD: Data for this study was obtained at baseline from Conexiones y Opciones Positivas en la Argentina 2 (COPA2). Participants (N = 360) were cisgender patients living with HIV who were lost to care, recruited from seven clinics serving people living with HIV in four Argentine urban centers. Cumulative burden of mental health conditions (i.e., depressive symptoms, problematic substance use, unhealthy alcohol use, and psychotic symptoms) was assessed. RESULTS: Every one-point increase in the number of mental health conditions present was associated with a decrement in patient-provider communication (b = - 0.22, p < .001), self-efficacy (b = - 0.13, p = .012), and motivation for adherence (b = - 0.11, p = .039). CONCLUSION: This study found cumulative burden of depression, problematic substance use, unhealthy alcohol use, and psychotic symptoms to be negatively associated with factors related to engagement in HIV care. Results highlight the importance of identification and treatment of challenges to mental health, in order to ameliorate their influence on engagement in HIV care.

RESUMEN

BACKGROUND: The spread of severe acute respiratory syndrome coronavirus 2, causative agent of the coronavirus disease 2019 (COVID-19), has necessitated widespread lockdown to mitigate the pandemic. This study examines the influence of resilience on the impact of COVID-related stress and enforced lockdown on mental health, drug use, and treatment adherence among people living with HIV (PLWH) in Argentina. SETTING: PLWH residing predominantly in Buenos Aires Metropolitan Area and urban regions of Argentina were identified from a private clinic electronic database. METHODS: Participants completed an anonymous online survey to evaluate the impact of COVID-19 on economic disruption, resilience, mental health outcomes (depression, anxiety, stress, and loneliness), adherence to HIV treatment, and substance use. We performed ordinary least squares and logistic regressions to test whether resilient coping buffered the impact of economic disruption on mental health and drug use during quarantine. RESULTS: A total of 1336 PLWH aged 18-82 were enrolled. The impact of economic disruption on mental health ΔF(1,1321) = 8.86, P = 0.003 and loneliness ΔF(1,1326) = 5.77, P = 0.016 was buffered by resilience. A 3-way interaction between resilient buffering, stress, and sex was significant ΔF(1,1325) = 4.76, P = 0.029. Participants reported less than excellent adherence to medication (33%), disruption to mental health services (11%), and disruption to substance abuse treatment (1.3%) during lockdown. DISCUSSION: The impact of COVID-stress and lockdown on emotional distress seemed mitigated by resilience coping strategies, and the buffering impact of resilience on perceived stress was greater among women. Results highlight PLWH's capacity to adhere to treatment in challenging circumstances and the importance of developing resilience skills for better coping with stress and adversity.

RESUMEN

Background: The COVID-19 pandemic pose significant risk to mental health and may disproportionately affect people living with HIV (PLWH). This study examined the interaction of social support and resilient coping in predicting depressive symptoms among PLWH. Methods : PLWH residing in Buenos Aires, Argentina and in Miami, Florida (US) were asked to complete an anonymous survey on the impact of COVID-19. Statistical analysis included ordinary least squares regression. Results: A total of 1,554 participants were included. Mean age was 47.30 years; 63.7 % were men. A test of three-way interaction of social support resilient coping study site indicated differences by site (b = -0.63.862, p = .043010, 95% CI [-1.24, -0.02.205, 1.52]). In Argentina, at higher social support and resilient coping, depressive symptoms were lowest. At lower social support and resilient coping, depressive symptoms were highest. Discussion: The impact of COVID-19 on mental health illustrates the need to develop innovative strategies to support resilience and to enhance coping with stress and adversity among PLWH.

RESUMEN

Introducción: Las personas que viven con VIH (PVV) tienen mayor riesgo de complicaciones de salud mental. Para mitigar la propagación del COVID-19 en nuestro país se estableció una cuarentena temprana. Estudiamos el impacto del estrés relacionado con COVID-19 y la cuarentena en hombres que tienen sexo con hombres que viven con VIH (HSHV) en Argentina.Materiales y métodos: Realizamos una encuesta anónima en abril-mayo de 2020. Se incluyeron PVV en seguimiento en una institución privada en Argentina. Se evaluaron la adherencia a medidas preventivas de COVID-19 y al tratamiento antirretroviral, el acceso a recursos, factores psicosociales y el consumo de sustancias durante la cuarentena. Este análisis se centró en los resultados de HSHV.Resultados: Entre 1336 participantes incluidos, 596 se autoreportaron HSHV (mediana de edad de 44 años, RIC 35-52). La adherencia a la cuarentena fue del 96,8%; la pérdida de empleo en el hogar 55,4%. Se observó interrupción en la obtención de medicamentos antirretrovirales en el 4,9% y el 29,9% reportó adherencia subóptima. Los problemas de salud mental fueron frecuentes: depresión (14,1%), soledad (15,6%) y ansiedad (20,2%).Conclusiones: Nuestro estudio evidenció alta adherencia a las medidas preventivas al inicio de la cuarentena y dificultades en el acceso a los servicios de salud. La pandemia de COVID-19 ha comprometido la economía del país; este estudio muestra su impacto en el acceso de los HSHV a recursos básicos. Dado que la salud mental de los HSHV ha sido afectada, la pandemia resalta la necesidad de una visión integral de la salud de nuestros pacientes


Background: People living with HIV (PLWH) are at increased risk of mental health complications. In order to mitigate the spread of COVID-19 in our country, an early quarantine was established. We studied the impact of COVID-19-related stress and quarantine in men who have sex with men living with HIV(MSMLH) in Argentina.Materials and methods: An anonymous survey was conducted between April and May 2020. PLWH in follow-up at a private institution in Argentina were included. We assessed adherence to preventive measures of COVID-19 and antiretroviral treatment, access to resources, psychosocial factors and substance use during quarantine. This analysis focused on MSMLH results.Results: Among 1336 participants included, 596 self-reported as MSMLH (median age 44, IQR 35-52). Quarantine adherence was 96.8%; household job loss 55.4%. Interruption to access to antiretroviral medication was observed in 4.9% and 29.9% reported suboptimal adherence. Mental health problems were common: depression (14.1%), loneliness (15.6%) anxiety (20.2%).Conclusions: Our study showed high adherence to preventive measures during the beginning of lockdown and difficulties to access health services. The COVID-19 pandemic has compromised the country's economy; this study shows its impact on MSMLH access to basic resources. Since MSMLH mental health has been affected, the pandemic highlights the need of a comprehensive approach to our patients' health

RESUMEN

This study evaluated the reasons for not taking antiretroviral treatment (ART) among women of reproductive age who are disengaged from HIV care (have missed pharmacy pickups and physician visits), with the goal of identifying strategies for reengagement in HIV care. Participants were cisgender women (n = 162), 18 to 49 years of age, and who completed sociodemographic, medical history, reasons why they were not taking ART, mental health, motivation, and self-efficacy assessments. Latent class analysis was used for analysis. Women who reported avoidance-based coping (avoid thinking about HIV) had higher depression (U = 608.5, z = -2.7, P = .007), lower motivation (U = 601, z = -2.8, P = .006), and lower self-efficacy (U = 644.5, z = -2.4, P = .017) than those not using this maladaptive strategy. As women living with HIV experience a disproportionate burden of poor health outcomes, interventions focused on the management of depression may improve HIV outcomes and prevent HIV transmission.

RESUMEN

Argentina has one of the highest suicide rates in Latin America and the Caribbean. Though people living with HIV are at increased risk for suicidal behavior, little research on suicide risk has been conducted among HIV-positive people in this region. This study examined risk factors for suicidal ideation among HIV-infected adults (N = 360) re-engaging in care in Argentina. Overall, 21% of participants reported suicidal ideation in the past week. In adjusted logistic regression models, younger age, increased depressive symptomatology, and drug abuse were associated with suicidal ideation (p < 0.05); decreased motivation for adherence and fewer months since initiating antiretroviral therapy approached significance (p = 0.07). Suicidal ideation was common in this sample of HIV-positive patients in Argentina. Findings highlight the need for routine risk assessment and interventions integrated into the HIV care continuum, addressing depression, substance use, and suicidal behavior.

RESUMEN

BACKGROUND: "Challenging" HIV-infected patients, those not retained in treatment, represent a critical focus for positive prevention, as linkage to care, early initiation of antiretroviral therapy, adherence and retention in treatment facilitate viral suppression, thus optimizing health and reducing HIV transmission. Argentina was one of the first Latin American countries to guarantee HIV prevention, diagnosis and comprehensive care services, including antiretroviral medication, which removed cost and access as barriers. Yet, dropout occurs at every stage of the HIV continuum. An estimated 110,000 individuals are HIV-infected in Argentina; of these, 70% have been diagnosed and 54% were linked to care. However, only 36% have achieved viral suppression and 31% of those diagnosed delayed entry to care. To achieve meaningful reductions in HIV infection at the community level, innovative strategies must be developed to re-engage patients. Motivational Interviewing (MI) is a patient-centered approach and has been used by therapists in Central and South America to enhance motivation and commitment in substance use and risk reduction. Our pilot feasibility study utilized culturally tailored MI in physicians to target patients not retained in treatment in public and private clinics in Buenos Aires, Argentina. Results demonstrated that a physician-based MI intervention was feasible and effective in enhanced and sustained patient adherence, viral suppression, and patient-physician communication and attitudes about treatment among these patients at 6 and 9 months post baseline. METHODS/DESIGN: This clinical trial seeks to extend these findings in public and private clinics in four urban population centers in Argentina, in which clinics (n = 6 clinics, six MDs per clinic site) are randomized to experimental (physician MI Intervention) (n = 3) or control (physician Standard of Care) (n = 3) conditions in a 3:3 ratio. Using a cluster randomized clinical trial design, the study will test the effectiveness of a physician-based MI intervention to improve and sustain retention, adherence, persistence, and viral suppression among "challenging" patients (n = 420) over 24 months. DISCUSSION: Results are anticipated to have significant public health implications for the implementation of MI to re-engage and retain patients in HIV treatment and care and improve viral suppression through high levels of medication adherence.

RESUMEN

Of those in the general population hospitalized for suicidal ideation and suicide attempts in Argentina, many reattempt suicide and are readmitted. However, few studies in Argentina have examined suicidal ideation and suicide-related behaviors among people living with HIV (PLHIV) and none have examined these factors among nonadherent PLHIV, though the prevalence of suicidal ideation in this group may be higher than in the general population and also than in other groups of PLHIV. This study of PLHIV in Buenos Aires, Argentina, examined the correlates of suicidal ideation in nonadherent PLHIV. Nonadherent patients with HIV (N = 118) were recruited from two clinics providing outpatient healthcare services to PLHIV in Buenos Aires, Argentina. Participants completed assessments on demographic characteristics, depression and suicidality, stigma, and self-efficacy. Participants were HIV-infected men (51%) and women (49%) with a median age of 40 years (IQR = 11). About half had completed high school or more, two-thirds were employed, and had a mean monthly income of 4196.79 (SD = 3179.64) Argentine pesos (USD$221). Thirty-three (28% [95% CI 20.3, 37.3]) participants reported suicidal ideation in the past two weeks, and one-third (35.6% [27.1, 44.9]) reported lifetime suicidal ideation. In bivariate analyses, attending a public clinic, being female, younger, unemployed, and experiencing greater stigma and depression were associated with suicidal ideation. In multivariable logistic regression, stigma interacted with the number of years since HIV diagnosis to predict suicidal ideation. The impact of stigma on suicidal ideation decreased with time since HIV diagnosis, suggesting that suicidal ideation may arise following HIV diagnosis due to perception of HIV-related stigma. Interventions to reduce perceived stigma during the period following HIV diagnosis may reduce suicidal ideation in this population. Organizational initiatives that explore HIV stigma microagressions in the healthcare setting may be needed to optimize health outcomes.
