Registro argentino de COVID-19 en VIH (Estudio COVIDARE): características clínicas, epidemiológicas y factores asociados a hospitalización

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.

Cost-effectiveness of COVID-19 vaccination in Latin America and the Caribbean: an analysis in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, and Peru.

OBJECTIVE: Our study analyzes the cost-effectiveness of the COVID-19 vaccination campaigns in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, and Peru. METHODS: Using a previously published SVEIR model, we analyzed the impact of a vaccination campaign (2021) from a national healthcare perspective. The primary outcomes were quality adjusted life years (QALYs) lost and total costs. Other outcomes included COVID-19 cases, hospitalizations, deaths, and life years. We applied a discount rate of 3% for health outcomes. We modeled a realistic vaccination campaign in each country (the realistic country-specific campaign). Additionally, we assessed a standard campaign (similar, "typical" for all countries), and an optimized campaign (similar in all countries with higher but plausible population coverage). One-way deterministic sensitivity analyses were performed. FINDINGS: Vaccination was health improving as well as cost-saving in almost all countries and scenarios. Our analysis shows that vaccination in this group of countries prevented 573,141 deaths (508,826 standard; 685,442 optimized) and gained 5.07 million QALYs (4.53 standard; 6.03 optimized). Despite the incremental costs of vaccination campaigns, they had a total net cost saving to the health system of US$16.29 billion (US$16.47 standard; US$18.58 optimized). The realistic (base case) vaccination campaign in Chile was the only scenario, which was not cost saving, but it was still highly cost-effective with an ICER of US$22 per QALY gained. Main findings were robust in the sensitivity analyses. INTERPRETATION: The COVID-19 vaccination campaign in seven Latin American and Caribbean countries -that comprise nearly 80% of the region- was beneficial for population health and was also cost-saving or highly cost-effective.

Safety of COVID-19 vaccines during pregnancy: A systematic review and meta-analysis.

BACKGROUND: Assessment of COVID-19 vaccines safety during pregnancy is urgently needed. METHODS: We conducted a systematic review and meta-analysis to evaluate the safety of COVID-19 vaccines, including their components and technological platforms used in other vaccines during pregnancy and animal studies to complement direct evidence. We searched literature databases from its inception to September 2021 without language restriction, COVID-19 vaccine websites, and reference lists of other systematic reviews and the included studies. Pairs of reviewers independently selected, data extracted, and assessed the risk of bias of the studies. Discrepancies were resolved by consensus. (PROSPERO CRD42021234185). RESULTS: We retrieved 8,837 records from the literature search; 71 studies were included, involving 17,719,495 pregnant persons and 389 pregnant animals. Most studies (94%) were conducted in high-income countries, were cohort studies (51%), and 15% were classified as high risk of bias. We identified nine COVID-19 vaccine studies, seven involving 309,164 pregnant persons, mostly exposed to mRNA vaccines. Among non-COVID-19 vaccines, the most frequent exposures were AS03 and aluminum-based adjuvants. A meta-analysis of studies that adjusted for potential confounders showed no association with adverse outcomes, regardless of the vaccine or the trimester of vaccination. Neither the reported rates of adverse pregnancy outcomes nor reactogenicity exceeded expected background rates, which was the case for ASO3- or aluminum-adjuvanted non-COVID-19 vaccines in the proportion meta-analyses of uncontrolled studies/arms. The only exception was postpartum hemorrhage after COVID-19 vaccination (10.40%; 95% CI: 6.49-15.10%), reported by two studies; however, the comparison with non-exposed pregnant persons, available for one study, found non-statistically significant differences (adjusted OR 1.09; 95% CI 0.56-2.12). Animal studies showed consistent results with studies in pregnant persons. CONCLUSION: We found no safety concerns for currently administered COVID-19 vaccines during pregnancy. Additional experimental and real-world evidence could enhance vaccination coverage. Robust safety data for non-mRNA-based COVID-19 vaccines are still needed.

Safety, immunogenicity, and effectiveness of COVID-19 vaccines for pregnant persons: A protocol for systematic review and meta analysis.

INTRODUCTION: Numerous vaccines have been evaluated and approved for coronavirus disease 2019 (COVID-19). Since pregnant persons have been excluded from most clinical trials of COVID-19 vaccines, sufficient data regarding the safety of these vaccines for the pregnant person and their fetus have rarely been available at the time of product licensure. However, as COVID-19 vaccines have been deployed, data on the safety, reactogenicity, immunogenicity, and efficacy of COVID-19 vaccines for pregnant persons and neonates are becoming increasingly available. A living systematic review and meta-analysis of the safety and effectiveness of COVID-19 vaccines for pregnant persons and newborns could provide the information necessary to help guide vaccine policy decisions. METHODS AND ANALYSIS: We aim to conduct a living systematic review and meta-analysis based on biweekly searches of medical databases (e.g., MEDLINE, EMBASE, CENTRAL) and clinical trial registries to systematically identify relevant studies of COVID-19 vaccines for pregnant persons. Pairs of reviewers will independently select, extract data, and conduct risk of bias assessments. We will include randomized clinical trials, quasi-experimental studies, cohort, case-control, cross-sectional studies, and case reports. Primary outcomes will be the safety, efficacy, and effectiveness of COVID-19 vaccines in pregnant persons, including neonatal outcomes. Secondary outcomes will be immunogenicity and reactogenicity. We will conduct paired meta-analyses, including prespecified subgroup and sensitivity analyses. We will use the grading of recommendations assessment, development, and evaluation approach to evaluate the certainty of evidence.

[Impact of COVID-19 related lockdown on the metabolic profile of people with HIV infection in Argentina]. / Impacto de la cuarentena por COVID-19 en el perfil metabólico de personas con infección por VIH en Argentina.

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.

Impacto de la cuarentena por COVID-19 en el perfil metabólico de personas con infección por VIH en Argentina / Impact of COVID-19 related lockdown on the metabolic profile of people with HIV infection in Argentina

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.

Clinical characteristics and outcomes of hospitalized patients with SARS-CoV-2 infection in a Latin American country: Results from the ECCOVID multicenter prospective study.

BACKGROUND: Clinical features and outcomes of SARS-CoV-2 infections diverge in different countries. The aim of this study was to describe clinical characteristics and outcomes in a cohort of patients hospitalized with SARS-CoV-2 in Argentina. METHODS: Multicenter prospective cohort study of ≥18 years-old patients with confirmed SARS-CoV-2 infection consecutively admitted to 19 hospitals in Argentina. Multivariable logistic regression models were used to identify variables associated with 30-day mortality and admission to intensive care unit (ICU). RESULTS: A total of 809 patients were analyzed. Median age was 53 years, 56% were males and 71% had at least one comorbidity. The most common comorbidities were hypertension (32%), obesity (23%) and diabetes (17%). Disease severity at admission was classified as mild 25%, moderate 51%, severe 17%, and critical 7%. Almost half of patients (49%) required supplemental oxygen, 18% ICU, and 12% invasive ventilation. Overall, 30-day mortality was 11%. Factors independently associated with ICU admission were male gender (OR 1.81; 95%CI 1.16-2.81), hypertension (OR 3.21; 95%CI 2.08-4.95), obesity (OR 2.38; 95%CI 1.51-3.7), oxygen saturation ≤93% (OR 6.45; 95%CI 4.20-9.92) and lymphopenia (OR 3.21; 95%CI 2.08-4.95). Factors independently associated with 30-day mortality included age ≥60 years-old (OR 2.68; 95% CI 1.63-4.43), oxygen saturation ≤93% (OR 3.19; 95%CI 1.97-5.16) and lymphopenia (OR 2.65; 95%CI 1.64-4.27). CONCLUSIONS: This cohort validates crucial clinical data on patients hospitalized with SARS-CoV-2 in Argentina.

Safety of components and platforms of COVID-19 vaccines considered for use in pregnancy: A rapid review.

BACKGROUND: Rapid assessment of COVID-19 vaccine safety during pregnancy is urgently needed. METHODS: We conducted a rapid systematic review, to evaluate the safety of COVID-19 vaccines selected by the COVID-19 Vaccines Global Access-Maternal Immunization Working Group in August 2020, including their components and their technological platforms used in other vaccines for pregnant persons. We searched literature databases, COVID-19 vaccine pregnancy registries, and explored reference lists from the inception date to February 2021 without language restriction. Pairs of reviewers independently selected studies through COVIDENCE, and performed the data extraction and the risk of bias assessment. Discrepancies were resolved by consensus. Registered on PROSPERO (CRD42021234185). RESULTS: We retrieved 6757 records and 12 COVID-19 pregnancy registries from the search strategy; 38 clinical and non-clinical studies (involving 2,398,855 pregnant persons and 56 pregnant animals) were included. Most studies (89%) were conducted in high-income countries and were cohort studies (57%). Most studies (76%) compared vaccine exposures with no exposure during the three trimesters of pregnancy. The most frequent exposure was to AS03 adjuvant, in the context of A/H1N1 pandemic influenza vaccines, (n = 24) and aluminum-based adjuvants (n = 11). Only one study reported exposure to messenger RNA in lipid nanoparticles COVID-19 vaccines. Except for one preliminary report about A/H1N1 influenza vaccination (adjuvant AS03), corrected by the authors in a more thorough analysis, all studies concluded that there were no safety concerns. CONCLUSION: This rapid review found no evidence of pregnancy-associated safety concerns of COVID-19 vaccines or of their components or platforms when used in other vaccines. However, the need for further data on several vaccine platforms and components is warranted, given their novelty. Our findings support current WHO guidelines recommending that pregnant persons may consider receiving COVID-19 vaccines, particularly if they are at high risk of exposure or have comorbidities that enhance the risk of severe disease.

Safety of COVID-19 vaccines, their components or their platforms for pregnant women: A rapid review.

BACKGROUND: Pregnant women with COVID-19 are at an increased risk of severe COVID-19 illness as well as adverse pregnancy and birth outcomes. Many countries are vaccinating or considering vaccinating pregnant women with limited available data about the safety of this strategy. Early identification of safety concerns of COVID-19 vaccines, including their components, or their technological platforms is therefore urgently needed. METHODS: We conducted a rapid systematic review, as the first phase of an ongoing full systematic review, to evaluate the safety of COVID-19 vaccines in pregnant women, including their components, and their technological platforms (whole virus, protein, viral vector or nucleic acid) used in other vaccines, following the Cochrane methods and the PRISMA statement for reporting (PROSPERO-CRD42021234185).We searched literature databases, COVID-19 and pregnancy registries from inception February 2021 without time or language restriction and explored the reference lists of relevant systematic reviews retrieved. We selected studies of any methodological design that included at least 50 pregnant women or pregnant animals exposed to the vaccines that were selected for review by the COVAX MIWG in August 2020 or their components or platforms included in the COVID-19 vaccines, and evaluated adverse events during pregnancy and the neonatal period.Pairs of reviewers independently selected studies through the COVIDENCE web software and performed the data extraction through a previously piloted online extraction form. Discrepancies were resolved by consensus. RESULTS: We identified 6768 records, 256 potentially eligible studies were assessed by full-text, and 37 clinical and non-clinical studies (38 reports, involving 2,397,715 pregnant women and 56 pregnant animals) and 12 pregnancy registries were included.Most studies (89%) were conducted in high-income countries. The most frequent study design was cohort studies (n=21), followed by surveillance studies, randomized controlled trials, and registry analyses. Most studies (76%) allowed comparisons between vaccinated and unvaccinated pregnant women (n=25) or animals (n=3) and reported exposures during the three trimesters of pregnancy.The most frequent exposure was to AS03 adjuvant in the context of A/H1N1 pandemic influenza vaccines (n=24), followed by aluminum-based adjuvants (n=11). Aluminum phosphate was used in Respiratory Syncytial Virus Fusion candidate vaccines (n=3) and Tdap vaccines (n=3). Different aluminum-based adjuvants were used in hepatitis vaccines. The replication-deficient simian adenovirus ChAdOx1 was used for a Rift Valley fever vaccine. Only one study reported exposure to messenger RNA (mRNA) COVID-19 vaccines that also used lipid nanoparticles. Except for one preliminary report about A/H1N1 influenza vaccination (adjuvant AS03) - corrected by the authors in a more thorough analysis, all studies concluded that there were no safety concerns. CONCLUSION: This rapid review found no evidence of pregnancy-associated safety concerns of COVID-19 vaccines that were selected for review by the COVAX MIWG or of their components or platforms when used in other vaccines. However, the need for further data on several vaccine platforms and components is warranted given their novelty. Our findings support current WHO guidelines recommending that pregnant women may consider receiving COVID-19 vaccines, particularly if they are at high risk of exposure or have comorbidities that enhance the risk of severe disease.

Mental Health, Coping, and Social Support Among People Living with HIV in the Americas: A Comparative Study Between Argentina and the USA During the SARS-CoV-2 Pandemic.

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.

Objetivos: Describir variables epidemiológicas clave durante el año 2020 (pandemia de COVID-19) con respecto a la prevención de la transmisión perinatal (TP) del VIH en Ciudad de Buenos Aires (CABA), comparando con períodos previos.Métodos: Análisis retrospectivo de los datos agregados de TP de las principales maternidades de CABA. El año pandémico (2020) se comparó con los años no pandémicos 2018 y 2019.Resultados: Se observó una reducción del total de nacimientos en 2020 en comparación con 2019 y 2018 (11.640 vs. 14.031 y 15,978, respectivamente). La proporción de nacidos vivos en madres VIH+ (MEV) fue 0,88% en 2020, sin diferencia con 2019 y 2018 (0,94% y 0,93%), p> 0,05 para todas las comparaciones. Entre las MEV, el diagnóstico intraparto fue del 2,9% para 2020, sin diferencias con 2019 (2,25%) y 2018 (9,3%), p> 0,05 (todas las comparaciones); el 8,8% comenzó el tratamiento antirretroviral con > 28 semanas de edad gestacional en 2020 frente al 16% y el 18,05% en 2018 y 2019 (p> 0,05, todas las comparaciones). La prevalencia de la carga viral indetectable en el momento del parto fue del 67% en 2020 frente al 64% en 2018 y del 65,4% en 2019 (p> 0,05, todas las comparaciones). La transmisión perinatal fue 0% en 2020 vs. 1,33% en 2018 y 2,25% 2019 (p> 0,05, todas las comparaciones).Conclusiones: En la primera ola de la pandemia de COVID-19 no se observaron cambios en la proporción de MEV asistidas, diagnóstico intraparto de VIH, inicio tardío del TARV y TP en CABA

Background: To describe key epidemiological variables in 2020 (COVID-19 pandemic) regarding prevention of mother-to-child transmission (MTCT) in Buenos Aires city (CABA) in comparison with previous periods. Methods: Retrospective analysis of aggregated MTCT data was gathered from six principal maternity hospitals in Buenos Aires city. Pandemic year (2020) was compared to non-pandemic years 2018-19 individually considering key epidemiological variables. Results: A reduction of total births was observed in 2020 compared to 2019 and 2018 (11640 vs. 14031 and 15978, respectively). Proportion of live births in HIV-infected women (HPW) was 0.88% in 2020 without difference with 2019 and 2018 (0.94% and 0.93%), p> 0.05 for all comparisons. Among HPW, intrapartum diagnosis was 2.9% for 2020, with no difference between 2019 (2.25%) and 2018 (9.3%), p>0.05 (all comparisons); 8.8% had antiretroviral therapy (ART) started > 28 weeks of gestational age in 2020 vs. 16% and 18.05% in 2018 and 2019 (p> 0.05, all comparisons). Prevalence of undetectable viral load at delivery was 67% in 2020 vs 64% in 2018 and 65.4% in 2019 (p> 0.05, all comparisons). Perinatal transmission was 0% in 2020 vs 1.33% in 2018 and 2.25% 2019 (p> 0.05, all comparisons) Conclusions: In first wave of COVID 19 pandemic no changes in the proportion of HPW assisted, HIV intrapartum diagnosis, late ART initiation and MTCT-rate was observed in CABA

Mental health, coping, and social support among people living with HIV in the Americas: A comparative study between Argentina and the USA during the SARS-CoV-2 pandemic.

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.

Impact of COVID-19-Related Stress and Lockdown on Mental Health Among People Living With HIV in Argentina.

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.

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
