RESUMO

We investigated changes in lifestyle, depressive symptoms, self-perception of health, and body weight changes of persons living with HIV (PLWH) during the COVID-19 social distancing (SD). In a Web-based cross-sectional survey, participants (n = 406) were questioned about lifestyle and health status before and during SD. Most responders were men, 50 + years old, high education level; 49.8% had their income reduced during SD. About 9% were diagnosed with COVID-19, of whom 13.5% required hospitalization. During SD: - most participants did not change their food intake, although 25% replaced healthy foods with unhealthy ones; -more than half mentioned poor sleep quality; -about 50% increased their sedentary behavior. Depressive symptoms (reported by 70.9%) were associated with sedentary behavior, poor sleep quality, and reduced income. About one-third had a negative perception of their health status, which was inversely associated with practicing physical exercises and positively associated with sedentarism and poor sleep quality. More than half increased their body weight, which was associated with a lower intake of vegetables. The older age reduced the odds of the three outcomes. Carefully monitoring PLWH regarding SD will enable early interventions toward health.


RESUMEN: En este trabajo investigamos los cambios en el estilo de vida, síntomas depresivos, autopercepción de salud y cambios en el peso corporal de las personas que viven con el VIH (PVCV) durante el distanciamiento social (DS) de COVID-19. En una encuesta transversal en línea, se preguntó a los participantes (n = 406) sobre el estilo de vida y el estado de salud antes y durante el DS. La mayoría de los encuestados eran hombres, mayores de 50 años, con alto nivel educativo. El 49,8% tuvo una disminución en sus ingresos durante el DS. El 9,1% fue diagnosticados con COVID-19, de los cuales 13,5% requirió hospitalización. Durante el DS: - la mayoría de los participantes no cambió su ingesta de alimentos, aunque el 25% reemplazó los alimentos saludables por los no saludables; más de la mitad mencionó mala calidad del sueño; cerca del 50% aumentó su comportamiento sedentario. Los síntomas depresivos (referidos por el 70,9%), fueron incrementados por el sedentarismo, la mala calidad del sueño y reducción de la renta. Cerca de un tercio tenía una percepción negativa de su estado de salud, que se redujo con la práctica de ejercicio físico y aumentó con el sedentarismo y la mala calidad del sueño. Más de la mitad aumentó su peso corporal, lo que se asoció con una menor ingesta de vegetales. Una edad más avanzada redujo las probabilidades de los tres desenlaces. El monitoreo cuidadoso de las PVCV con respecto al DS permitirá intervenciones tempranas para la salud.

RESUMO

BACKGROUND: People living with HIV might have a poor or delayed response to vaccines, mainly when CD4 cell counts are low, and data concerning COVID-19 vaccines in this population are scarce. This prospective cohort study assessed the safety and immunogenicity of the inactivated SARS-CoV-2 vaccine CoronaVac in people with HIV compared with people with no known immunosuppression. METHODS: In this prospective cohort study, adults (aged ≥18 years) living with HIV who were regularly followed up at the University of Sao Paulo HIV/AIDS outpatient clinic in Sao Paulo, Brazil, were included in the study. Eligibility for people with HIV was independent of antiretroviral use, HIV viral load, or CD4 cell count. Adults with no known immunosuppression with CoronaVac vaccination history were included as a control group. CoronaVac was given intramuscularly in a two-dose regimen, 28 days apart. Blood was collected before vaccine administration and 6 weeks after the second dose (day 69). Immunogenicity was assessed at baseline (day 0), before second vaccine (day 28), and 6 weeks after second vaccine dose (day 69) through SARS-CoV-2 IgG titre and seroconversion, neutralising antibody (NAb) positivity and percentage activity, and factor increase in IgG geometric mean titres (FI-GMT). We investigated whether HIV status and CD4 count (<500 or ≥500 cells per µL) were associated with CoronaVac immunogenicity by use of multivariable models adjusted for age and sex. FINDINGS: Between Feb 9, 2021, and March 4, 2021, 776 participants were recruited. Of 511 participants included, 215 (42%) were people with HIV and 296 (58%) were people with no known immunosuppression. At 6 weeks after the second vaccine dose (day 69), 185 (91%) of 204 participants with HIV and 265 (97%) of 274 participants with no known immunosuppression had seroconversion (p=0·0055). 143 (71%) of 202 participants with HIV were NAb positive compared with 229 (84%) of 274 participants with no known immunosuppression (p=0·0008). Median IgG titres were 48·7 AU/mL (IQR 26·6-88·2) in people with HIV compared with 75·2 AU/mL (50·3-112·0) in people with no known immunosuppression (p<0·0001); and median NAb activity was 46·2% (26·9-69·7) compared with 60·8% (39·8-79·9; p<0·0001). In people with HIV who had CD4 counts less than 500 cells per µL seroconversion rates, NAb positivity, and NAb activity were lower than in those with CD4 counts of at least 500 cells per µL. In multivariable models for seroconversion, NAb positivity, IgG concentration, and NAb activity after a complete two-dose regimen, adjusted for age and sex, people with HIV who had CD4 counts of at least 500 cells per µL and people with no known immunosuppression had higher immunogenicity than did people with HIV with CD4 counts less than 500 cells per µL. No serious adverse reactions were reported during the study. INTERPRETATION: Immunogenicity following CoronaVac in people with HIV seems strong but reduced compared with people with no known immunosuppression. Our findings highlight the need for strategies to improve vaccine immunogenicity in people with HIV.

RESUMO

Although antiretroviral therapy has revolutionized the care of HIV-infected patients, it has been associated with metabolic abnormalities. Hence, this study was planned to investigate the effects of fish oil on lipid profile, insulin resistance, and body fat distribution in HIV-infected Brazilian patients on antiretroviral therapy, considering that marine omega-3 fatty acids seem to improve features of the metabolic syndrome. We conducted a randomized, parallel, placebo-controlled trial that assessed the effects of 3 g fish oil/day (540 mg of eicosapentaenoic acid plus 360 mg of docosahexaenoic acid) or 3 g soy oil/day (placebo) on 83 HIV-infected Brazilian men and non-pregnant women on antiretroviral therapy. No statistically significant relationships between fish oil supplementation and longitudinal changes in triglyceride (p = 0.335), low-density lipoprotein cholesterol (p = 0.078), high-density lipoprotein cholesterol (p = 0.383), total cholesterol (p = 0.072), apolipoprotein B (p = 0.522), apolipoprotein A1 (p = 0.420), low-density lipoprotein cholesterol/apolipoprotein B ratio (p = 0.107), homeostasis model assessment for insulin resistance index (p = 0.387), body mass index (p = 0.068), waist circumference (p = 0.128), and waist/hip ratio (p = 0.359) were observed. A low dose of fish oil did not alter lipid profile, insulin resistance, and body fat distribution in HIV-infected patients on antiretroviral therapy.
