Introduction We hypothesized that nutritional deficiency would be common in a cohort of postpartum, human immunodeficiency virus (HIV)-infected women and their infants. Methods Weight and height, as well as blood concentrations of retinol, α-tocopherol, ferritin, hemoglobin, and zinc, were measured in mothers after delivery and in their infants at birth and at 6-12 weeks and six months of age. Retinol and α-tocopherol levels were quantified by high performance liquid chromatography, and zinc levels were measured by atomic absorption spectrophotometry. The maternal body mass index during pregnancy was adjusted for gestational age (adjBMI). Results Among the 97 women 19.6% were underweight. Laboratory abnormalities were most frequently observed for the hemoglobin (46.4%), zinc (41.1%), retinol (12.5%) and ferritin (6.5%) levels. Five percent of the women had mean corpuscular hemoglobin concentrations < 31g/dL. The most common deficiency in the infants was α-tocopherol (81%) at birth; however, only 18.5% of infants had deficient levels at six months of age. Large percentages of infants had zinc (36.8%) and retinol (29.5%) deficiencies at birth; however, these percentages decreased to 17.5% and 18.5%, respectively, by six months of age. No associations between infant micronutrient deficiencies and either the maternal adjBMI category or maternal micronutrient deficiencies were found. Conclusions Micronutrient deficiencies were common in HIV-infected women and their infants. Micronutrient deficiencies were less prevalent in the infants at six months of age. Neither underweight women nor their infants at birth were at increased risk for micronutrient deficiencies.

Mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) infection remains an important cause of new HIV infections worldwide, especially in low and middle-resource limited countries. Safety data from studies involving pregnant women and prenatal antiretroviral (ARV) exposure are still needed once these studies are often small and with a limited duration to assess adverse drug reactions (ADR). The aim of this study was to estimate the incidence of ADR related to the use of antiretroviral therapy (ART) in pregnant women in two referral centers in Rio de Janeiro State. A prospective study was carried out from February 2005 to May 2006. Women were classified according to their ART status during pregnancy diagnosis: ARV-experienced (ARTexp) or ARV-naïve (ARTn). Two hundred fourteen HIV-infected pregnant women were included: 36 ARTexp and 178 ARTn. ARTexp women have not experienced ADR. Among ARTn, 20.2% presented ADR. Incidence rate of ADR was 70.8 per 1000 person-months and the most common ADRs observed were: gastrointestinal (belly or abdominal cramps, diarrhea, nausea and vomit) in 16.3%, cutaneous (pruritus and rash) in 6.2%, anemia (2.2%) and hepatitis (1.7%). The frequency of obstetrical complications, pre-term delivery, low birth weight and birth abnormalities was low in this population. ADRs ranged from mild to moderate intensity, none of them being potentially fatal. Only in a few cases it was necessary to discontinue ART. In conclusion, the high effectiveness of ARV for HIV prevention of MTCT (PMTCT) overcomes the risk of ADR.

OBJECTIVES: To describe laboratory abnormalities among HIV-infected women and their infants with standard and increased lopinavir/ritonavir (LPV/r) dosing during the third trimester of pregnancy. METHODS: We evaluated data on pregnant women from NISDI cohorts (2002-2009) enrolled in Brazil, who received at least 28 days of LPV/r during the third pregnancy trimester and gave birth to singleton infants. RESULTS: 164 women received LPV/r standard dosing [(798/198 or 800/200 mg/day) (Group 1)] and 70 increased dosing [(> 800/200 mg/day) (Group 2)]. Group 1 was more likely to have advanced clinical disease and to use ARVs for treatment, and less likely to have CD4 counts > 500 cells/mm³. Mean plasma viral load was higher in Group 2. There were statistically significant, but not clinically meaningful, differences between groups in mean AST, ALT, cholesterol, and triglycerides. The proportion of women with Grade 3 or 4 adverse events was very low, with no statistically significant differences between groups in severe adverse events related to ALT, AST, total bilirubin, cholesterol, or triglycerides. There were statistically significant, but not clinically meaningful, differences between infant groups in ALT and creatinine. The proportion of infants with Grade 3 or 4 adverse events was very low, and there were no statistically significant differences in severe adverse events related to ALT, AST, BUN, or creatinine. CONCLUSION: The proportions of women and infants with severe laboratory adverse events were very low. Increased LPV/r dosing during the third trimester of pregnancy appears to be safe for HIV-infected women and their infants.

OBJETIVO: Analisar a viabilidade da testagem rápida para o HIV entre gestantes na admissão à maternidade e de intervenções para reduzir a transmissão perinatal do HIV. MÉTODOS: Amostra de conveniência de mulheres que desconheciam sua situação sorológica para o HIV quando admitidas para o parto em maternidades públicas do Rio de Janeiro, RJ, e de Porto Alegre, RS, entre março de 2000 e abril de 2002. As mulheres foram aconselhadas e testadas com teste rápido Determine HIV1/2 na maternidade. Infecção pelo HIV foi confirmada pelo algoritmo brasileiro para o diagnóstico da infecção pelo HIV. A transmissão intra-útero foi determinada pelo PCR-DNA-HIV. Foram realizadas análises descritivas dos dados sociodemográficos, número de gestações e de abortos prévios, número de visitas de pré-natal, momento da testagem para o HIV, resultado do teste rápido para o HIV, intervenções recebidas pelos recém-natos e de transmissão vertical do HIV, de acordo com cada cidade. RESULTADOS: A prevalência de HIV entre as mulheres foi 6,5% (N=1.439) em Porto Alegre e 1,3% (N=3.778) no Rio de Janeiro. A maioria foi testada durante o trabalho de parto em Porto Alegre e no pós-parto, no Rio de Janeiro. Cento e quarenta e quatro crianças nasceram de 143 mulheres infectadas pelo HIV. Todos os recém-natos receberam ao menos a profilaxia com zidovudina oral, exceto um em cada cidade. Foi possível evitar qualquer exposição ao leite materno em 96,8% e 51,1% dos recém-natos em Porto Alegre e no Rio de Janeiro, respectivamente. A zidovudina injetável foi administrada durante o trabalho de parto para 68,8% dos recém-natos em Porto Alegre e 27,7% no Rio de Janeiro. Entre aqueles com amostras de sangue coletadas até 48 horas do nascimento, a transmissão intra-útero foi confirmada em quatro casos no Rio de Janeiro (4/47) e em seis casos em Porto Alegre (6/79). CONCLUSÕES: A estratégia mostrou-se factível nas maternidades do Rio de Janeiro e de Porto Alegre. Esforços devem ser empreendidos para maximizar a testagem durante o trabalho de parto. Forte suporte social precisa ser acoplado a essa estratégia para garantir o acesso dessa população ao sistema de saúde após a alta da maternidade.

OBJECTIVE: To assess the feasibility of HIV rapid testing for pregnant women at maternity hospital admission and of subsequent interventions to reduce perinatal HIV transmission. METHODS: Study based on a convenience sample of women unaware of their HIV serostatus when they were admitted to delivery in public maternity hospitals in Rio de Janeiro and Porto Alegre, Brazil, between March 2000 and April 2002. Women were counseled and tested using the Determine HIV1/2 Rapid Test. HIV infection was confirmed using the Brazilian algorithm for HIV infection diagnosis. In utero transmission of HIV was determined using HIV-DNA-PCR. There were performed descriptive analyses of sociodemographic data, number of previous pregnancies and abortions, number of prenatal care visits, timing of HIV testing, HIV rapid test result, neonatal and mother-to-child transmission interventions, by city studied. RESULTS: HIV prevalence in women was 6.5% (N=1,439) in Porto Alegre and 1.3% (N=3.778) in Rio de Janeiro. In Porto Alegre most of women were tested during labor (88.7%), while in Rio de Janeiro most were tested in the postpartum (67.5%). One hundred and forty-four infants were born to 143 HIV-infected women. All newborns but one in each city received at least prophylaxis with oral zidovudine. It was possible to completely avoid newborn exposure to breast milk in 96.8% and 51.1% of the cases in Porto Alegre and Rio de Janeiro, respectively. Injectable intravenous zidovudine was administered during labor to 68.8% and 27.7% newborns in Porto Alegre and Rio de Janeiro, respectively. Among those from whom blood samples were collected within 48 hours of birth, in utero transmission of HIV was confirmed in 4 cases in Rio de Janeiro (4/47) and 6 cases in Porto Alegre (6/79). CONCLUSIONS: The strategy proved feasible in maternity hospitals in Rio de Janeiro and Porto Alegre. Efforts must be taken to maximize HIV testing during labor. There is a need of strong social support to provide this population access to health care services after hospital discharge.

RESULTADOS: La prevalencia de HIV entre las mujeres fue de 6,5% (N=1.439) en Porto Alegre y 1,3% (N=3,778) en Rio de Janeiro. La mayoría fue evaluada durante el trabajo de parto en Porto Alegre y en el postparto, en Rio de Janeiro. Ciento y cuarenta y cuatro niños nacieron de 143 mujeres infectadas por el HIV. Todos los recién nacidos recibieron al menos la profilaxia con zidovudina oral, excepto uno en cada ciudad. Fue posible evitar cualquier exposición a la leche materna en 96,8% y 51,1% de los recién nacidos en Porto Alegre y en Rio de Janeiro, respectivamente. La zidovudina inyectable fue administrada durante el trabajo de parto a 68,8% de los recién nacidos en Porto Alegre y 27,7% en Rio de Janeiro. Entre aquellos con muestras de sangre colectadas hasta 48 horas de nacimiento, la transmisión intra-útero fue confirmada en cuatro casos en Rio de Janeiro (4/47) y en seis casos en Porto Alegre (6/79). CONCLUSIONES: La estrategia se mostró factible en las maternidades de Rio de Janeiro y de Porto Alegre. Esfuerzos deben ser emprendidos para maximizar la evaluación durante el trabajo de parto. Fuerte soporte social precisa ser acoplado a esa estrategia para garantizar el acceso de dicha población al sistema de salud posterior a ser dado de alta de la maternidad.
