Personal and Network-Related Factors Associated to Diagnosis Disclosure Reactions for Children and Adolescents Living with HIV.

The process of human immunodeficiency virus (HIV) diagnosis disclosure for vertically infected young people living with HIV has proven decisive for acceptance/adherence to treatment. Herein, we present a cross-sectional study aiming at evaluating how individual and network related variables are associated with reactions to HIV disclosure among them. We used the egocentric approach with a structured questionnaire applied to individuals aged 15-25 years in an HIV referral center in Rio de Janeiro, Brazil. Outcome variable referred to adoption or not of risk behavior after diagnostic disclosure, was classified as "good"/"bad" reactions. Results showed that, of the 80 study participants, 25% reported a "bad reaction" to diagnostic disclosure, an outcome that was more common for patients with at least one friend in their social support network (OR 4.81; 95%CI [1.05-22.07]). In conclusion, a "bad reaction" to HIV serological disclosure may be associated with inadequate structure of the individual's social support network.

RESUMEN: El proceso de divulgación del diagnóstico del virus de inmunodeficiencia humana (VIH) es decisivo para la aceptación/adhesión a tratamiento de los jóvenes infectados verticalmente que viven con VIH. Presentamos un estudio transversal con el objetivo de evaluar cómo variables individuales y de red están asociadas con reacciones a la divulgación del VIH entre ellos. Utilizamos el enfoque egocéntrico por medio de un cuestionario estructurado aplicado a personas de 15-25 años en un Centro de Referencia para VIH en Río de Janeiro, Brasil. La variable de resultado se refiere a la adopción o no de comportamiento de riesgo después de la divulgación del diagnóstico, clasificadas como reacciones "buena"/"mala". Los resultados mostraron que, de los 80 participantes del estudio, el 25% reportó una "mala reacción" a la divulgación diagnóstica. Este resultado fue más común en pacientes con al menos un amigo en su red de apoyo social (OR:4.81; IC95% [1.05-22.07]). Como conclusión, una "mala reacción" a la divulgación serológica del VIH puede estar asociada con una estructura inadecuada de la red de apoyo social del individuo.

Prognostic Factors in Children and Adolescents with Lymphomas and Vertical Transmission of HIV in Rio de Janeiro, Brazil: A Multicentric Hospital-Based Survival Analysis Study.

Lymphomas related to HIV are generally aggressive and have a poor prognosis, despite the use of combined antiretroviral therapy (cART) and effective chemotherapy treatment. To determine survival and prognostic factors in children and adolescents living with HIV (CLWH) in Rio de Janeiro (RJ), Brazil, who developed lymphomas, we performed a retrospective and observational study of vertically infected CLWH aged from 0 to 20 incomplete years during1995 to 2018 at five reference centers for cancer and HIV/AIDS treatment. Of the 25 lymphomas, 19 were AIDS-defining malignancies (ADM) and 6 were non-AIDS-defining malignancies (NADM). The 5-year overall survival (OS) and 5-year event-free survival (EFS) probabilities were both 32.00% (95% CI = 13.72-50.23%), and the 5-year disease-free survival (DFS) probability was 53.30% (95% CI = 28.02-78.58%). In the multivariate Cox regression analysis, performance status 4 (PS 4) was considered a poor prognostic factor for OS (HR 4.85, 95% CI = 1.81-12.97, p = 0.002) and EFS (HR 4.95, 95% CI = 1.84-13.34, p = 0.002). For the DFS, higher CD4+ T-cell counts were considered a better prognostic factor (HR 0.86, 95% CI = 0.76-0.97, p = 0.017) in the multivariate Cox regression analysis. This study demonstrates, for the first time, survival and prognostic factors for CLWH who developed lymphomas in RJ, Brazil.

Clinical Manifestations and Complications of Children With COVID-19 Compared to Other Respiratory Viral Infections: A Cohort Inpatient Study From Rio de Janeiro, Brazil.

Introduction: The coronavirus disease-2019 (COVID-19) clinical manifestations in children and adolescents are diverse, despite the respiratory condition being the main presentation. Factors such as comorbidities and other respiratory infections may play a role in the initial presentation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This study aims to describe the epidemiological aspects, clinical, and laboratory manifestations of pediatric patients admitted to a tertiary pediatric hospital in Rio de Janeiro, diagnosed with COVID-19, and compare these with other viral conditions during the first year of the SARS-CoV-2 pandemic. Methods: All patients under 18 years of age that were admitted with upper airway infection were enrolled and followed up for 30 days. The main dependent variable was the laboratorial diagnosis of SARS-CoV-2, and independent variables were studied through logistic regression. Results: A total of 533 patients were recruited, and 105 had confirmed SARS-CoV-2 infection. Detection of other viruses occurred in 34% of 264 tested participants. Six patients died (two in SARS-CoV-2 infected group). The variables independently associated with COVID-19 were older age (OR = 1.1, 95% CI = 1.0-1.1), lower leukocytes count at entry (OR = 0.9, 95% CI = 0.8-0.9), and contact with suspected case (OR = 1.6, 95% CI = 1.0-2.6). Patients with COVID-19 presented higher odds to be admitted in an intensive care unit (OR = 1.99, 95% CI = 1.08-3.66). Conclusions: Even during the SARS-CoV-2 pandemic, several other respiratory viruses were present in admitted pediatric patients. Variables associated with COVID-19 infection were older age, lower leukocytes count at entry, and a domiciliary suspect contact. Although patients with COVID-19 were more frequently admitted to ICU, we did not observe higher mortality in this group.

Incidence and Clinical Description of Lymphomas in Children and Adolescents with Vertical Transmission of HIV in Rio de Janeiro, Brazil, in Pre- and Post-Combined Antiretroviral Therapy Eras: A Multicentric Hospital-Based Survival Analysis Study.

The incidence of cancer in children living with HIV (CLWH) is high and lymphomas are the most common type of cancer in this population. The combined antiretroviral therapy (cART) changed the natural history of HIV infection. To determine the incidence and profile of these CLWH malignancies in Rio de Janeiro (RJ), Brazil, we conducted a retrospective and observational study of vertically infected CLWH, ranging from 0−20 incomplete years, from 1995 to 2018, at five reference centers. The study period was divided into three eras in accordance with the widespread use of cART in Brazil. 1306 patients were included. Of the 25 lymphomas found, 19 were AIDS-defining malignancies (ADM); 6 were non-AIDS-defining malignancies (NADM). The incidence rate (IR) of lymphoma developing was 1.70 per 1000 children-year (95% CI 1.09−2.50). ADM development IR decreased from 2.09−1.75−0.19 per 1000 children-year (p < 0.001) through cART eras. Cumulative Nelson−Aalen hazards of developing ADM over a 20-year period were 3.73% in the Early-cART era, 3.07% in the Mid-cART era, and 0.32% in the Late-cART era (p = 0.013). This study demonstrates the IR of lymphoma in CLWH in RJ, Brazil, as well as the benefit of cART in reducing ADM and death occurrence in the Post-cART era.
