Objective-Results regarding potential adverse effects of antiretroviral drugs during pregnancy are discrepant and few studies, most from Europe, have provided information about pregnancy outcomes of those already on treatment at conception. The aim of this study was to investigate the impact of antiretrovirals on pregnancy outcome according to the timing of treatment initiation in relation to pregnancy in a cohort of Brazilian HIV infected pregnant women.Methods-A prospective cohort of 696 pregnancies followed-up in one single center between 1996 and 2006 was studied. Patients in receipt of antiretrovirals before pregnancy were compared with those treated after the first trimester. The outcomes evaluated were preterm delivery (PTD): < 37 weeks; severe PTD (< 34 weeks); low birth weight (LBW): < 2500 g; very LBW: < 1500 g.
Results-Patients on pre-conception use of ARV had higher rates of LBW (33.3% vs. 16.5%; p = 0.0002), and a similar trend for PTD (26.3% % vs. 17.7%; p = 0.09). Stratification by type of therapy (dual vs. HAART) according to timing of initiation of ARV showed that patients in use of preconception HAART have a higher rate of PTD (20.2% vs. 10.2%, p = 0.03) and LBW (24.2% vs. 10.2%, p = 0.002). After adjusting for several factors, pre-conception HAART was associated with an increased risk for PTD (AOR: 5.0; 95% CI: 1.5 -17.0, p = 0.009) and LBW (OR: 3.6; 95% CI: 1.7 -7.7, p = 0.001).Conclusions-We identified an increased risk for LBW and PTD in patients in receipt of HAART prior to pregnancy.
HIV vertical transmission in Brazil was reduced to a level similar to other countries with the most effective prevention programs using a multidisciplinary team approach. A high level of compliance for use of anti-retroviral drugs, the provision of health education to mothers, and use of formula for all exposed infants.
BackgroundWe aim to investigate possible maternal- and pregnancy-related factors associated with the development of Congenital Zika Syndrome (CZS) in children of mothers with probable gestational infection.MethodsThis case-control study, we recruited mother-infant pairs between May 2015 and October 2017 in a pediatric infectious disease clinic in Rio de Janeiro. Inclusion criteria required either that the mother reported Zika infection symptoms during pregnancy or that the infant presented with clinical or imaging features of the CZS. Exclusion criteria included detection of an alternative cause for the patient’s presentation or negative polymerase chain reaction assays for Zika in all specimens tested within 12 days from the beginning of maternal symptoms. Infants with CZS (CDC definition) were selected as cases and infants without CZS, but with probable maternal Zika virus infection during pregnancy, were selected as controls. Maternal and pregnancy-related informations were collected and their relationship to the presence of congenital anomalies due to CZS was assessed by Fisher exact or Mann-Whitney test.ResultsOut of the 42 included neonates, 24 (57.1%) were diagnosed with CZS (cases). The mean maternal age at the birth was 21 years old. The early occurrence of maternal symptoms during pregnancy was the only variable associated with CZS (odds ratio = 0.87, 95% CI: 0.78–0.97).Case’s mothers presented symptoms until the 25th week of gestational age (GA), while control’s mothers presented until 36th weeks of GA. Income; illicit drug, alcohol, or tobacco use during pregnancy; other infections during pregnancy (including previous dengue infection) were not associated with CZS.ConclusionsOur study corroborates the hypothesis that Zika virus infection earlier in pregnancy is a risk factor to the occurrence of congenital anomalies in their fetuses.
Thirty six cases of acute disseminated paracoccidioidomycosis in 3 to 12 year-old children, natives of the state of Rio de Janeiro, were seen in the period 1981-1996. All patients were residents in the rural region of 15 counties, scattered on the Southwestern part of this state. The rural region of two neighboring counties, where 16 cases (44.4%) occurred, was visited. It exhibited the environmental conditions that are considered favorable to the survival of P. brasiliensis. The most important of these conditions, abundant watercourses and autochthonous forest, are distributed on well defined and limited areas, in which the dwellings are also localized. Probably, a careful epidemiological study of forthcoming cases of the disease in children may facilitate the search for the micro-niche of the fungus.
This group of adolescents seems to have sexual behavior similar to that of HIV-uninfected. Since this is an experimented antiretroviral population, new drugs may be necessary for adequate viral suppression to avoid HIV mother-to-child transmission. Follow-up of this third generation of HIV-exposed infants needs to be addressed within HIV adolescent care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
