Risk factors for seroconversion of HIV among children exposed in the State of Santa Catarina, 2007-2017

Abstract Objectives: to estimate the proportion of seroconversion cases among infants exposed to HIV and verify the risk factors associated. Methods: this was a historical cohort study conducted in the State of Santa Catarina between 2007 and 2017. The data were obtained from the Notifable Diseases Information System (SINAN – Portuguese acronym) that records HIV-infected pregnant women and HIV-exposed infants. The public health service monitored the infants from birth to 18 months of age to determine whether HIV seroconversion occurred. Results: a total of 5,554 HIV-infected pregnant women were included in the study (mean age 26.7±6.5 years). They were predominantly white, with poor education level, and were diagnosed with HIV until the 2nd trimester of pregnancy. A total of 4,559 records of HIV-exposed infants were screened, of which 130 cases (2.9%) of seroconversion were confrmed. Non-use of antiretroviral drugs during pregnancy (OR=9.31, CI95%=5.97-14.52; p<0.001) and breastfeeding (OR=3.10, CI95%=1.34-7.20; p=0.008) were independent risk factors for seroconversion. Conclusions: these data demonstrate gaps in prenatal care, regarding adherence to treatment and monitoring of HIV-infected mothers, resulting in new cases of HIV among children, which could be avoided.

Preventing vertical HIV virus transmission: hospital care assessment

OBJECTIVES

assess the implementation of actions to prevent vertical transmission of HIV.

METHODS

a retrospective cohort study conducted in two maternity hospitals in the city of Montes Claros, State of Minas Gerais. All women admitted for childbirth diagnosed with HIV and their respective newborns were included from 2014 to 2017. Data were collected from medical records and analyzed descriptively.

RESULTS

population consisted of 46 pairs of mothers and newborns. Management was considered inadequate in 30 cases of parturient/postpartum women (65.2%) and 14 cases of newborns (30.4%). The main reasons for inadequate maternal management were lack of pharmacological inhibition of lactation (53.3%) and counseling/consent for HIV testing (43.3%). For newborns, late onsetoffirst dose ofZidovudine (50.0%) and no prescriptionofNevirapine (28.6%).

CONCLUSIONS

important prevention opportunities were missed, pointing to the need for improved care.

[Incidence and mortality of children and teenagers with AIDS: challenges in the southern region of Brazil]

The objective of this study is to describe the time trend of coefficients of incidence and mortality associated with AIDS in children and adolescents. An ecological time trend study was conducted among individuals under 14 living in the regional context of high incidence of AIDS - Porto Alegre and the State of Rio Grande do Sul - from 1996 to 2012. For this purpose, a segmented regression model was adjusted for age categories and place of residence. AIDS morbidity and mortality indicators in Porto Alegre are still higher than those registered in the State, the southern region and other areas of the country. In Porto Alegre, 59.1% of cases (371/628) occurred in children under four years of age, the incidence showed peaks in the period and the mortality dropped from 9 to 2 per 100,000. A significant decreasing in annual percentage change in mortality was observed especially in children under 1 year of age in Porto Alegre. This drop may be related to prevention and treatment of pregnant women. The challenge is to identify possible fragilities of the STD/AIDS Program and its vulnerable points in order to make specific interventions and investments with a greater impact potential.

Feeding of children exposed to the human immunodeficiency virus at birth

The aim was to characterize feeding aspects of children born exposed to the Human Immunodeficiency Virus. Cross-sectional study was developed at a referral hospital for infectious diseases in Fortaleza-Ceará, Brazil, between January and June 2010. The sample consisted of 62 mothers who provided information on 64 children born exposed to the virus. In the nursing consultation, the Assessment Scale of Care Skills for Children Exposed to Human Immunodeficiency Virus at Birth and forms for sociodemographic and dietary characterization were used. It was found that 57.8% of children had inappropriate intake of milk, 55.0% had inappropriate complementary feeding, 87.0% of mothers had a high capacity to offer milk powder and, in relation to complementary feeding, the ability ranged from moderate (45.7%) to high (48.5%). Thirteen nursing diagnoses showing feeding problems and deficits in care that require nursing interventions appropriate to the social context of each patient were identified.

Evaluation of preventive measures for mother-to-child transmission of HIV in Aracaju, State of Sergipe, Brazil

INTRODUCTION: The main route of human immunodeficiency virus (HIV) infection in children is from mother to child. The preventive measures established for the Aids Clinical Trial Group protocol 076 (ACTG 076) significantly reduces HIV vertical transmission rates. This study aims to evaluate the implementation of the ACTG 076 protocol in the maternity units of State of Sergipe, Brazilian northeast. METHODS: This is a descriptive, retrospective study with a quantitative approach, with HIV positive women and children exposed, attending a Maternity reference for high-risk pregnancies. Data were obtained from patient records registered in the years 1994 to 2010. RESULTS: Amongst the 110 pregnant women and exposed newborns, the ACTG 076 protocol was fully utilized in only 31.8% of the participants. During the prenatal period, zidovudine (ZDV) was taken by 79.1% of the pregnant women. Only 49.1% of HIV seropositive patients used ZDV during delivery. Two (1.8%) children were considered infected and 50 (45.5%) do not have a conclusive diagnosis to date. CONCLUSIONS: There were significant deficiencies in the prevention of mother-to-child transmission of HIV, including lack of compliance with the three phases of the ACTG 076 protocol; inadequacies in prenatal care; inappropriate mode of delivery and lack of adequate follow up of exposed children.

Disparities in mother-to-child transmission in Northeast Brazil: regional failures within successful country programs

Perinatal HIV prevention has been successful in developing countries but disparities in success between rich countries and poor countries have also been observed. Access to prevention of mother-to-child transmission (PMTCT) remains a challenge in many developing countries. In 2007, the Ministry of Health launched the Plan to Reduce the Vertical Transmission of HIV and Syphilis in Brazil to address this need. A cross-sectional study of children living in families affected by HIV was conducted in Ceara State, Northeast Brazil between June 2008 and January 2009 to explore socioeconomic effects of HIV status. Proportion of children with an HIV-positive test was calculated and stratified by age to estimate the impact of PMTCT programs. Chi-square test was employed to compare those proportions. Stata™10.0 software was used for the calculation. We interviewed 437 adults who were visiting the hospital for a consultation or to pickup medication who also had a child less than 13 years of age living with them. They also provided information about other household members (n=1789). Our study showed that children infected with HIV or who live in a household with one or both parents infected with HIV or dead from AIDS live in families of low social class and educational achievement. Seroprevalence is not lower in the cohort of those children 0-2 as compared to 3-4 and 5-12 years of age. Even in Brazil, with its successful PMTCT program overall, there are great disparities among sites. Data from the sites reported here are equivalent to many poor areas in sub-Saharan Africa. This argues that global concern for targeting areas most affected by the epidemic must consider areas within some of the most prosperous countries in the world.
