Viral suppression and adherence among HIV-infected children and adolescents on antiretroviral therapy: results of a multicenter study / Supressão viral e adesão entre crianças e adolescentes vivendo com HIV na terapia antirretroviral: resultados de um estudo multicêntrico

OBJECTIVE: To evaluate treatment adherence among perinatally-infected pediatric human immunodeficiency virus (HIV) patients followed in pediatric centers in Brazil. METHODS: This was a cross-sectional multicenter study. Medical records were reviewed and adherence scale, assessment of caregivers' quality of life (WHOQOL-BREF), anxiety, depression, and alcohol/substances use/abuse were assessed. Outcomes included self-reported 100% adherence in the last three days and HIV viral load (VL) < 50 copies/mL. Statistical analyses included contingency tables and respective statistics, and multivariable logistic regression. RESULTS: 260 subjects were enrolled: 78% children and 22% adolescents; 93% of caregivers for the children and 77% of adolescents reported 100% adherence; 57% of children and 49% of adolescents had VL < 50 copies/mL. In the univariate analyses, HIV diagnosis for screening due to maternal infection, lower caregiver scores for anxiety, and higher scores in physical and psychological domains of WHOQOL-BREF were associated with 100% adherence. Shorter intervals between pharmacy visits were associated with VL < 50 copies/mL (p ≤ 0.01). Multivariable regression demonstrated that caregivers who did not abuse alcohol/other drugs (OR = 0.49; 95% CI: 0.27-0.89) and median interval between pharmacy visits < 33 days (OR = 0.97; 95% CI: 0.95-0.98) were independently associated with VL < 50 copies/mL; whereas lower caregiver scores for anxiety (OR = 2.57; 95% CI: 1.27-5.19) and children's HIV diagnosis for screening due to maternal infection (OR = 2.25; 95% CI: 1.12-4.50) were found to be independently associated with 100% adherence. CONCLUSIONS: Pediatric HIV programs should perform routine assessment of caregivers' quality of life, and anxiety and depression symptoms. In this setting, pharmacy records are essential to help identify less-than-optimal adherence. .

OBJETIVO: Avaliar a adesão ao tratamento antirretroviral entre portadores de HIV acompanhados em centros pediátricos. MÉTODOS: Trata-se de estudo transversal multicêntrico. Os prontuários ambulatoriais foram revistos e aplicadas escala de adesão, avaliação de qualidade de vida (WHOQOL-BREF), ansiedade, depressão e uso indevido de álcool/substâncias entre cuidadores. Os desfechos incluíram autorrelato 100% de adesão nos últimos três dias e carga viral do HIV (CV) < 50 cópias/mL. RESULTADOS: 260 indivíduos foram incluídos, 79% crianças e 21% adolescentes; 93% das crianças e 77% dos adolescentes relataram 100% de adesão; 57% das crianças e 49% dos adolescentes tinham CV < 50 cópias /mL. Na análise univariada, diagnóstico do HIV por triagem devido à infecção materna, cuidador com pontuação menor para ansiedade e maior nos domínios físico e psicológico do WHOQOL-BREF se mostraram independentemente associados a 100% de adesão. Intervalos mais curtos entre visitas de farmácia foram associados com CV < 50 cópias /mL (p ≤ 0,01). Regressão multivariada mostrou que os cuidadores sem abuso de álcool/outras drogas (OR = 0,49; IC95% 0,27-0,89) e o intervalo médio entre visitas de farmácia < 33 dias (OR = 0,97; IC95% 0,95-0,98) foram associados com CV < 50 cópias/mL; cuidador com menores escores para ansiedade (OR = 2,57; IC95% 1,27-5,19) e diagnóstico de crianças por triagem devido à infecção materna (OR = 2,25; IC95% 1,12-4,50) foram associados com 100% de adesão. CONCLUSÕES: Programas de HIV pediátrico devem avaliar qualidade de vida e sintomas de ansiedade e depressão dos cuidadores. Registros de farmácia são essenciais na identificação de adesão ...

First report of Angiostrongylus cantonensis (Nematoda: Metastrongylidae) in Achatina fulica (Mollusca: Gastropoda) from Southeast and South Brazil

The rat lungworm Angiostrongylus cantonensis is a worldwide-distributed zoonotic nematode that can cause human eosinophilic meningoencephalitis. Here, for the first time, we report the isolation of A. cantonensis from Achatina fulica from two Brazilian states: Rio de Janeiro (specifically the municipalities of Barra do Piraí, situated at the Paraiba River Valley region and São Gonçalo, situated at the edge of Guanabara Bay) and Santa Catarina (in municipality of Joinville). The lungworms were identified by comparing morphological and morphometrical data obtained from adult worms to values obtained from experimental infections of A. cantonensis from Pernambuco, Brazil, and Akita, Japan. Only a few minor morphological differences that were determined to represent intra-specific variation were observed. This report of A. cantonensis in South and Southeast Brazil, together with the recent report of the zoonosis and parasite-infected molluscs in Northeast Brazil, provide evidence of the wide distribution of A. cantonensis in the country. The need for efforts to better understand the role of A. fulica in the transmission of meningoencephalitis in Brazil and the surveillance of molluscs and rodents, particularly in ports, is emphasized.
