Incidência e preditores de gestação em mulheres com HIV/Aids no Rio de Janeiro
OBJETIVO: Identificar incidencia y predictores de la primera gestación entre mujeres con VIH/Sida. MÉTODOS: Estudio prospectivo de cohorte conducido en Rio de Janeiro, Sureste de Brasil, entre 1996 y 2003. El estudio incluyó 225 mujeres acompañadas hasta la primera gestación o hasta el primer evento considerado censura (histerectomÃa, ligadura tubárica, menopausia, 50 años de edad, pérdida de acompañamiento, óbito o final de diciembre de 2003). Se estimaron las tasas de incidencia de gestación y de aborto, y se usaron modelos de riesgos proporcionales de Cox para identificar las caracterÃsticas de la visita de inclusión asociadas con el riesgo de gestación. RESULTADOS: Las mujeres fueron acompañadas por 565 persona/años, con promedio de acompañamiento de 3 años por mujer. La edad promedio fue de 32 años (DP:7), y 54,7% eran blancas. Sesenta gestaciones fueron observadas en 39 mujeres y 18 resultaron en abortos inducidos (tasas de incidencia de 6,9% y 2,1% mujeres/año, respectivamente). Las gestaciones repetidas ocurrieron en 33,3% de las mujeres (13/39). Fue observado el mayor riesgo de gestación entre mujeres jóvenes (HR=3,42; IC 95%:1,69;6,95) y entre aquellas que vivÃan con sus parejas (HR=1,89; IC 95%: 1,00;3,57). El menor riesgo de gestación estuvo asociado a la mayor escolaridad (HR=0,43; IC95%:0,19;0,99) y al uso de terapia antirretroviral (HR=0,61; IC95%:0,31;1,17). CONCLUSIONES: La incidencia de gestación en la cohorte fue menor al compararse con aquella observada en la población general. CaracterÃsticas sociodemográficas deben ser consideradas en el manejo de los deseos reproductivos de mujeres VIH-positivas en edad reproductiva. Los programas de VIH/SIDA deben incluir consejos reproductivos y contraceptivos para prevenir la transmisión del VIH para sus parejas y prole.OBJETIVO: Identificar incidência e preditores incidência da primeira gestação entre mulheres com HIV/Aids.

METHODS: Prospective cohort study was conducted in Rio de Janeiro, southeastern Brazil, between 1996 and 2003. This study comprised 225 women with HIV/AIDS followed up until their first pregnancy or first censored event (hysterectomy, tubal ligation, menopause, 50 years of age, loss to follow-up, death or the end of December 2003). Pregnancy and abortion rates were estimated, and Cox proportional hazards models were used to identify baseline characteristics associated with pregnancy risk. RESULTS: The women were followed up for 565 person/years with a median follow-up of 3 years per women. The mean age was 32 years (SD: 7), and 54.7% were white. There were 60 pregnancies in 39 women, and 18 were terminated (induced abortions), accounting for a rate of 6.9% and 2.1% women/year, respectively. Repeated pregnancies occurred in 33.3% of the women (13/39). Higher pregnancy risk was seen among younger women (HR=3.42; 95%CI: 1.69;6.95) and those living with their partners (HR=1.89; 95%CI: 1.00;3.57). Lower pregnancy risk was associated with higher education level (HR=0.43; 95%CI: 0.19;0.99) and use of antiretroviral therapy (HR=061; 95%CI: 0.31;1.17). CONCLUSIONS: Lower pregnancy rates were found in our cohort than in the general population. Sociodemographic characteristics should be taken into consideration in the management of reproductive health in HIV-positive childbearing age women. Reproductive and family planning counseling must be incorporated into HIV/AIDS programs for women to help preventing HIV transmission to their partners and offspring
Teste rápido para o HIV como estratégia de prevenção da transmissão vertical no Brasil
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.OBJETIVO: Analizar la viabilidad de evaluación rápida del HIV entre gestantes en la admisión en la maternidad y de intervenciones para reducir la transmisión perinatal del HIV. MÉTODOS: Muestra de conveniencia de mujeres que desconocÃan su situación serológica para el HIV al ser admitidas para el parto en maternidades públicas de Rio de Janeiro (Sureste) y de Porto alegre (Sur de Brasil), entre marzo de 2000 y abril de 2002. Las mujeres fueron aconsejadas y evaluadas con prueba rápida Determine HIV1/2 en la maternidad. Infección por el HIV fue confirmada por el algoritmo brasilero para el diagnóstico de la infección por el HIV. La transmisión intra- útero fue determinada por el PCR-DNA-HIV. Fueron realizados análisis descriptivos de los datos sociodemográficos, número de gestaciones y de abortos previos, número de visitas de prenatal, momento de la evaluación para el HIV, resultado de la prueba rápida para el HIV, intervenciones recibidas por los recién nacidos y de transmisión vertical del HIV, de acuerdo con cada ciudad. 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 mayorÃa 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.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.

Factors Associated with Colposcopy-Histopathology Confirmed Cervical Intraepithelial Neoplasia among HIV-Infected Women from Rio De Janeiro, Brazil
Introduction: Despite the availability of preventive strategies (screening tests and vaccines), cervical cancer continues to
impose a significant health burden in low- and medium-resourced countries. HIV-infected women are at increased risk for
infection with human papillomavirus (HPV) and thus development of cervical squamous intraepithelial neoplasia (CIN).
Methods:Study participants included HIV-infected women enrolling the prospective open cohort of Evandro Chagas
Clinical Research Institute, Oswaldo Cruz Foundation (IPEC/FIOCRUZ). At cohort entry, women were subjected to
conventional Papanicolaou test, HPV-DNA test and colposcopy; lesions suspicious for CIN were biopsied. Histopathology
report was based on directed biopsy or on specimens obtained by excision of the transformation zone or cervical
conization. Poisson regression modeling was used to assess factors associated with CIN2+diagnosis.
Results:The median age of the 366 HIV-infected women included in the study was 34 years (interquartile range: 28–41
years). The prevalence of CIN1, CIN2 and CIN3 were 20.0%, 3.5%, and 2.2%, respectively. One woman was found to have
cervical cancer. The prevalence of CIN2+was 6.0%. Factors associated with CIN2+diagnosis in the multivariate model were
age,years compared to350 cells/mm3 (aPR = 6.03 95%CI 1.50–24.3) and concomitant
diagnosis of vulvar and/or vaginal intraepithelial lesion (aPR = 2.68 95%CI 0.99–7.24).
Discussion:Increased survival through wide-spread use of highly active antiretroviral therapy might allow for the
development of cervical cancer. In Brazil, limited cytology screening and gynecological care adds further complexity to the
HIV-HPV co-infection problem. Integrated HIV care and cervical cancer prevention programs are needed for the prevention
of cervical cancer mortality in this group of wome

maior incidência, prevalência, persistência e recorrência após tratamentos de lesões pré-invasivas do colo
uterino (NIC II ou III). O objetivo foi verificar o risco de recorrência de NIC II/III em mulheres infectadas pelo
HIV (HIV+) e não infectadas (HIV-) em uma coorte tratada pela exérese eletrocirúrgica da zona de transformação
do colo uterino (EZT).
TIPO DE ESTUDO E LOCAL: Estudo de tipo coorte realizado no Instituto Fernandes Figueira/Fundação
Oswaldo Cruz (IFF/Fiocruz).
MÉTODOS: 60 HIV+ e 209 HIV- foram incluÃdas em uma coorte após terem sido submetidas à EZT para tratamento
de NIC II/III. Foi considerado como recorrência o diagnóstico histopatológico de NIC II/III. Foram estudadas
as seguintes variáveis possivelmente confundidoras: idade no tratamento e ao final do seguimento, grau
histológico da doença intra-epitelial tratada, comprometimento de margens, adequação da colposcopia no
seguimento, contagem de linfócitos CD4+, carga viral de HIV e tipo de terapia antiretroviral.
RESULTADOS: Dentre as 60 mulheres HIV+, 6 apresentaram doença recorrente durante o seguimento. De
209 HIV-, 7 apresentaram uma nova lesão precursora. O risco relativo de recorrência de doença nas HIV+
foi de 4,21 (IC 95% 1,42-12,43). Uma curva de Kaplan-Meyer mostra que o risco de recorrência é significativamente
maior em mulheres HIV+ (teste de log-rank: P = 0,0111).
CONCLUSÃO: Mulheres HIV+ em nossa coorte apresentaram risco de recorrência pelo menos 42% maior
do que mulheres HIV-. Essas pacientes devem fazer parte de um protocolo de rastreio e acompanhamento
rigoroso para identificação e tratamento adequado das lesões precursoras do câncer de colo uterino.CONTEXT AND OBJECTIVE: Human immunodeficiency virus (HIV)-infected women have higher incidence, prevalence, persistence and recurrence of pre-invasive cervical lesions (CIN II or III). The aim here
was to investigate the risk of recurrence of CIN II/III among HIV-infected women (HIV+) and uninfected women in a cohort treated by means of large-loop excision of the transformation zone (LLETZ). DESIGN AND SETTING: Cohort study conducted at Instituto Fernandes Figueira/Fundação Oswaldo Cruz (IFF/Fiocruz). METHODS: 60 HIV+ and 209 HIV-negative patients were included in a cohort for follow-up after undergoing LLETZ to treat CIN II/III. A histopathological diagnosis of CIN II/III during the follow-up was taken to constitute recurrence. The following possible confounding variables were assessed: age at treatment and at end
of follow-up; histological grade of intraepithelial disease treated; surgical margin involvement; adequacy of colposcopy during the follow-up; CD4+ lymphocyte count; HIV viral load; and type of antiretroviral therapy. RESULTS: Among the 60 HIV+ women, six showed recurrent disease during the follow-up. However, among the 209 HIV-negative women, seven showed a new precursor lesion. The relative risk of disease recurrence in the HIV+ women was 4.21 (95% CI = 1.42 to 12.43). The Kaplan-Meyer curve showed that the risk of recurrence was significantly higher among HIV+ women (log-rank test: P = 0.0111). CONCLUSION: The HIV+ women in our cohort presented a risk of CIN II/III recurrence at least 42% higher
than among the HIV-negative women. These patients should form part of a rigorous screening and followup protocol for identification and appropriate treatment of cervical cancer precursor lesions

Pregnancy incidence, outcomes and associated factors in a cohort of women living with HIV/AIDS in Rio de Janeiro, Brazil, 1996-2016
Abstract The aim of this research was to analyze pregnancy incidence and associated factors in a cohort of 753 women living with HIV/AIDS (WLWHA) in Rio de Janeiro, Brazil, from 1996 to 2016. Women aged 18-49 years who were not on menopause (surgical or natural) and did not have a tubal ligation were eligible for the study. Data were collected by medical professionals during initial and follow-up visits. Person-time pregnancy incidence rates were calculated throughout the follow-up period. Pregnancy incidence-associated factors were investigated by univariate and multiple analyzes, using an extension of the Cox survival model. Follow-up visits recorded 194 pregnancies, with an incidence rate of 4.01/100 person-years (95% CI: 3.47; 4.60). A higher pregnancy incidence was associated with CD4 nadir ≥ 350 cells/mm³, use of an antiretroviral regimen not containing Efavirenz, and prior teenage pregnancy. In turn, women with a viral load ≥ 50 copies/mL, age ≥ 35 years old, with two or more children and using a highly effective contraceptive method showed a lower incidence. Results showed a significant reduction in pregnancy incidence after 2006, a significant reduction in female sterilization from 1996 to 2016, and a high rate of cesarean sections. The association found between pregnancy incidence and the use of contraceptive methods and virological control markers suggests a good integration between HIV/AIDS and reproductive health services. The high rate of cesarean section delivery indicates the need to improve childbirth care
Incidence of antiretroviral adverse drug reactions in pregnant women in two referral centers for HIV prevention of mother-to-child-transmission care and research in Rio de Janeiro, Brazil
Mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) infection
remains an important cause of new HIV infections worldwide, especially in low and middleresource
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, preterm
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
