ABSTRACT

Fetal and placental growth disorders are common in maternal human immunodeficiency virus (HIV) infection and can be attributed to both the infection and comorbidities not associated with HIV. We describe placental growth disorders and adverse reproductive outcomes in HIV-infected pregnant women whose delivery occurred between 2001-2014 in Vitoria, Brazil. Cases with gestational age (GA) ≥ than 22 weeks validated by ultrasonography, with placental and fetal weight dimensions at birth, were studied. Outcomes were summarized as proportions of small (SGA), appropriate (AGA), and large (LGA) for GA when the z-score values were below -1.28, between -1.28 and +1.28, or above +1.28, respectively. Of 187 fetal attachment requisitions, 122(65.2%) women and their newborns participated in the study. The median maternal age was 28 years and 81(66.4%) underwent ≥ 6 prenatal visits. A total of 81(66.4%) were diagnosed before current pregnancy; 68(55.7%) exhibited criteria for acquired immunodeficiency syndrome (AIDS); 64(52.4%) had detectable viral load; 25(20.5%) cases presented SGA placental weight and 6(4.9%) SGA placental thickness. SGA placental area was observed in 41(33.6%) cases, and among the SGA placental weight cases 12(48%) were also SGA fetal weight. Preterm birth (PTB) occurred in 15.6%(19/122) of cases; perinatal death in 4.1%(5/122) and HIV vertical transmission in 6 of 122 (4.9%). Women, ≥36 years old, were 5.7 times more likely to have PTB than those under 36. Also, patients with AIDS-defining criteria were 3.7 times more likely to have PTB. Prenatal care was inversely associated with PTB. Statistically significant associations were observed between AGA placental area and Protease Inhibitor usage and between SGA placental weight and SGA area. We found a prevalence of placental growth disorders in HIV-infected pregnant women and values higher than international reference values. The restriction of placental growth was a common disorder, possibly attributed to virus effects or a combination of antiretroviral regimens.

ABSTRACT

OBJECTIVE: To estimate the prevalence of anal HPV infection, genotype distribution, intraepithelial neoplasia (AIN) and correlates in a cohort of HIV-infected patients attending at Sexually Transmitted Infections (STI) clinic in Brazil. STUDY DESIGN: A descriptive analysis was performed which includes, demographic, behavioral and clinical data. Anal specimens from HIV-positive men and women were collected during a regular visit and they were used for cytology and histopathology tests, as well as for HPV molecular identification. RESULTS: A total of 223 patients (143 females and 80 males) were enrolled in the study and, HPV was identified in 68.6% of the sample. The frequency of HR-HPV, HPV16/18 and multiple HPV infection were similar in both groups. The upstream regulatory region (URR) sequencing was carried out in 38 samples identified as HPV16-positive, and European variants were the most frequent (69.2%), followed by Africans (25.6%) and Asiatic-Americans (5.1%). Having more than 20 sexual partners was associated with multiple HPV infection (p = 0.000) while, anal sex and the first intercourse before 15 years of age was a risk factor for any HPV infection (p = 0.001). Being MSM (men who have sex with men) was a risk factor for any HPV and multiple infections (p = 0.002). The CD4 count >500 cells/mm3 was a protective factor for the HPV16/18 (p = 0.048) and multiple infections (p = 0.023), and the undetectable viral load and HAART treatment were both protective for any HPV (p = 0.010), HR-HPV (p = 0.091) and multiple infections (p = 0.006). Abnormal anoscopy was found in 23.7% (53/223) of the total number of patients, and this was significantly associated with all types of investigated HPV infections (p<0.0001). CONCLUSIONS: In this study, anal HPV infection was common among young HIV-positive men and women, particularly in MSM. Anal cancer screening in patients at risk, such as those who are HIV-positive, and mainly those with anal HPV infection and a history of STI, will increase the likelihood of detecting anal intraepithelial neoplasia.

ABSTRACT

Early miscarriage is still a concern, and viral infections are recognised as one of the causes of this adverse outcome. The causal relationship between HPV and miscarriage remains controversial. The aim of the study was to evaluate whether HPV infection indeed may occur in both the maternal and placental tissue in cases of miscarriage. Decidual and chorionic villi fragments (n = 118) were dissected from 81 miscarriage cases, 68 spontaneous and 13 intentional. HPV DNA was detected using the consensus primers MY09/11; in eight cases (9.9%, 8/81), seven of which (10.3%) were from spontaneous miscarriages and one (7.7%), was from an intentional miscarriage. The deciduas (4/8) and chorionic villi (5/8) were both infected with HPV. A reverse line blot was used to genotype HPV positive samples and revealed HPV6, 11, 58, 66 and 82. Although the results obtained cannot infer an association between HPV and pregnancy loss, it cannot be ruled out. Impact Statement What is already known on this subject? Miscarriages are considered to be the most common complication in pregnancy. Several possible causes of miscarriage have been considered, and the role of infections as one of those is confirmed, especially during the second trimester of pregnancy. The prevalence of HPV in conception products is still questionable. However, an HPV infection should not be ignored and its association with miscarriage must be considered. What the results of this study add? The present study reveals the presence of HPV in the foetal and maternal tissues of conception. What the implications are of these findings for clinical practice and/or further research? This issue deserves further investigation aiming to clarify the role of HPV in miscarriage cases; which are mainly related to the specific type and grade of tissues' abnormalities found co-topographically with a virus presence.

ABSTRACT

INTRODUCTION: Maternal HIV infection and related co-morbidities may have two outstanding consequences to fetal health: mother-to-child transmission (MTCT) and adverse perinatal outcomes. After Brazilian success in reducing MTCT, the attention must now be diverted to the potentially increased risk for preterm birth (PTB) and intrauterine fetal growth restriction (IUGR). OBJECTIVE: To determine the prevalence of PTB and IUGR in low income, antiretroviral users, publicly assisted, HIV-infected women and to verify its relation to the HIV infection stage. PATIENTS AND METHODS: Out of 250 deliveries from HIV-infected mothers that delivered at a tertiary public university hospital in the city of Vitória, state of Espírito Santo, Southeastern Brazil, from November 2001 to May 2012, 74 single pregnancies were selected for study, with ultrasound validated gestational age (GA) and data on birth dimensions: fetal weight (FW), birth length (BL), head and abdominal circumferences (HC, AC). The data were extracted from clinical and pathological records, and the outcomes summarized as proportions of preterm birth (PTB, < 37 weeks), low birth weight (LBW, < 2500 g) and small (SGA), adequate (AGA) and large (LGA) for GA, defined as having a value below, between or beyond the ± 1.28 z/GA score, the usual clinical cut-off to demarcate the 10th and 90th percentiles. RESULTS: PTB was observed in 17.5%, LBW in 20.2% and SGA FW, BL, HC and AC in 16.2%, 19.1%, 13.8%, and 17.4% respectively. The proportions in HIV-only and AIDS cases were: PTB: 5.9 versus 27.5%, LBW: 14.7% versus 25.0%, SGA BW: 17.6% versus 15.0%, BL: 6.0% versus 30.0%, HC: 9.0% versus 17.9%, and AC: 13.3% versus 21.2%; only SGA BL attained a significant difference. Out of 15 cases of LBW, eight (53.3%) were preterm only, four (26.7%) were SGA only, and three (20.0%) were both PTB and SGA cases. A concomitant presence of, at least, two SGA dimensions in the same fetus was frequent. CONCLUSIONS: The proportions of preterm birth and low birth weight were higher than the local and Brazilian prevalence and a trend was observed for higher proportions of SGA fetal dimensions than the expected population distribution in this small casuistry of newborn from the HIV-infected, low income, antiretroviral users, and publicly assisted pregnant women. A trend for higher prevalence of PTB, LBW and SGA fetal dimensions was also observed in infants born to mothers with AIDS compared to HIV-infected mothers without AIDS.

Introdução: A infecção materna pelo HIV e comorbidades associadas podem ter duas consequências para a saúde fetal, a transmissão vertical e o desfecho perinatal adverso. Após o sucesso em reduzir a transmissão vertical, deve-se dar atenção ao risco potencial de nascimento pretermo (PRT) e de restrição de crescimento fetal (RCF). Objetivo: Determinar a prevalência de PRT e RCF em gestantes de baixa renda, infectadas pelo HIV, usuárias de terapia antirretroviral atendidas em hospital público terciário e verificar sua relação com o estágio da infecção viral. Casuística e métodos: Dentre os 250 partos de gestantes infectadas pelo HIV, ocorridos em um hospital universitário na cidade de Vitória, estado do Espírito Santo, Sudeste do Brasil, entre novembro de 2001 e maio de 2012, foram selecionadas 74 gestações não-gemelares, com idade gestacional confirmada por ultrassonografia e as dimensões neonatais: peso ao nascer (PN), comprimento (CN) e perímetros cefálico (PC) e abdominal (PA). Os dados foram extraídos dos prontuários clínicos e laboratoriais e o desfecho sumarizado como nascimento pretermo (PRT < 37 semanas), baixo peso ao nascer (BPN < 2500g) e como pequeno (PIG), adequado (AIG) e grande (GIG) para a IG, definido como tendo um menor valor, entre e maior que ± 1.28 z/IG escore, o critério clínico usual para demarcar os percentis 10 e 90. Resultados: PRT foi observado em 17,5%, BPN em 20,2% e PN, CN, PC e PA PIG em 16,2%, 19,1%, 13,8% e 17,4%, respectivamente. As respectivas proporções observadas nos casos de HIV e AIDS foram: PRT: 5,9 versus 27,5%, BPN: 14,7% versus 25,0%, PFN PIG: 17,6% versus 15,0%, CN: 6,0% versus 30,0%, PC: 9,0% versus 17,9% e PA: 13,3% versus 21,2%; somente a diferença de CN PIG foi estatisticamente significativa. Dentre 15 neonatos com BPN, oito (53,3%) eram somente PRT, quatro (26,7%) PIG somente e três (20,0%) PRT e PIG. Concomitância no mesmo caso de pelo menos duas dimensões PIG foi observada frequentemente. ...

ABSTRACT

The purpose of this study was to describe the reproductive profile and frequency of genital infections among women living in the Serra Pelada, a former mining village in the Pará state, Brazil. A descriptive study of women living in the mining area of Serra Pelada was performed in 2004 through interviews that gathered demographics and clinical data, and assessed risk behaviors of 209 randomly-selected women. Blood samples were collected for rapid assay for HIV; specimens were taken for Pap smears and Gram stains. Standard descriptive statistical analyses were performed and prevalence was calculated to reflect the relative frequency of each disease. Of the 209 participants, the median age was 38 years, with almost 70% having less than four years of education and 77% having no income or under 1.9 times the minimum wage of Brazil. About 30% did not have access to health care services during the preceding year. Risk behaviors included: alcohol abuse, 24.4%; illicit drug abuse, 4.3%; being a sex worker, 15.8%; and domestic violence, 17.7%. Abnormal Pap smear was found in 8.6%. Prevalence rates of infection were: HIV, 1.9%; trichomoniasis, 2.9%; bacterial vaginosis, 18.7%; candidiasis, 5.7%; Chlamydial-related cytological changes, 3.3%; and HPV-related cytological changes, 3.8%. Women living in this mining area in Brazil are economically and socially vulnerable to health problems. It is important to point out the importance of concomitant broader strategies that include reducing poverty and empowering women to make improvements regarding their health.

El propósito de este estudio fue describir el perfil reproductivo y la frecuencia de infecciones genitales en mujeres que viven en la población minera Serra Pelada en el Estado de Pará, Brasil. Se realizó un estudio descriptivo de las mujeres que vivían en la zona minera de Serra Pelada en 2004 mediante entrevistas en las que se recabarondatos demográficos y clínicos y se examinaron las conductas de riesgo de 209 mujeres seleccionadas aleatoriamente. Se tomaron muestras de sangre para pruebas rápidas de detección de anticuerpos contra el VIH y muestras de tejido para análisis citológico y tinción de Gram. Se calculó la prevalencia y se utilizaron pruebas estadísticas descriptivas estándares para caracterizar la frecuencia relativa de cada enfermedad. La mediana de la edad de las 209 participantes fue de 38 años; 70% tenía menos de cuatro años de escolaridad y 77% no tenía ingresos o estos eran inferiores a 1,9 veces elsalario mínimo en Brasil. Alrededor de 30% no tuvo acceso a servicios de salud durante el año previo. Entre las conductas de riesgo estaban: consumo de bebidas alcohólicas (24,4%) y de drogas ilícitas (4,3%), ser trabajadora sexual (15,8%) y violencia doméstica (17,7%). Se encontraron resultados anormales a la prueba citológica en8,6% de las participantes. Las prevalencias de infección fueron: 1,9% de VIH, 2,9% de tricomoniasis, 18,7% de vaginosis bacteriana y 5,7% de candidiasis; 3,3% presentó alteracionescitológicas asociadas con la infección por clamidia y 3,8% alteraciones citológicas asociadas con el virus de papiloma humano. Las mujeres de esta zona minera de Brasil son económica y socialmente vulnerables a problemas de salud. Es importante señalar la importancia de estrategias concomitantes más amplias que abarquen la reducción de la pobreza y el empoderamiento de las mujeres para lograr mejoras en su salud.

ABSTRACT

OBJECTIVE: To describe the sociodemographic profile and health problems of inmates in a women's prison. METHODS: A descriptive study was conducted from March to September 1997 in a women's prison in the state of Espírito Santo, Brazil. All inmates were invited to participate in the study. A total of 121 women aged more than 18 years were interviewed. A structured questionnaire was used to collect data on sociodemographics, clinical and criminal past history. Following the interview, subjects underwent clinical and gynecological examination. RESULTS: Of 121 women included in the study, the mean age was 30.2 years (SD 8.98) and the mean of schooling was 4.8 years (SD 3.50). All participants reported previous sexual activity, the mean age of the first sexual intercourse was 15.2 years (SD 2.55) ranging from 9 to 27 years. Previous STDs were reported by 28%; 12 (9.9%) were pregnant at the time. Teenage pregnancy was often reported. Most women reported no use of either any contraceptive methods or condoms. Tubal ligation was seen in 19.8% and abnormal Pap smear in 26.9%. CONCLUSIONS: Knowledge about health problems inside the prison system can contribute to promoting and increasing social rehabilitation. However, effective results could be seen only with collaboration between public health authorities and the prison system.

ABSTRACT

OBJETIVO: Identificar o perfil sociodemográfico e as condições de saúde das mulheres encarceradas em penitenciária feminina. MÉTODOS: Foi realizado estudo descritivo de março a setembro de 1997, em penitenciária feminina do Estado do Espírito Santo. Todas as presidiárias foram convidadas a participar da pesquisa. Participaram 121 mulheres com idade superior a 18 anos, avaliadas por meio de entrevista aplicada, explorando informações sociodemográficas, clínicas e criminais, registradas em questionário estruturado, seguida de exame clínico-ginecológico. RESULTADOS: Um total de 121 mulheres foram incluídas. A média de idade das participantes foi de 30,2 anos (DP 8,98) e de escolaridade, 4,8 anos (DP 3,50). Todas já haviam tido atividade sexual pregressa; a idade média do primeiro coito foi de 15,2 anos (DP 2,55), variando de nove a 27 anos; e 28 por cento apresentavam história de doença sexualmente transmissível (DST). Doze (9,9 por cento) mulheres estavam grávidas no momento da entrevista. História de gravidez na adolescência foi freqüente. A maioria não adotava nenhum método contraceptivo e nem fazia uso de preservativos. Laqueadura tubária foi observada em 19,8 por cento e citologia cervical anormal em 26,9 por cento. CONCLUSÕES: O conhecimento sobre problemas de saúde existentes dentro do sistema carcerário pode contribuir para fortalecer e ampliar o papel de reabilitação que lhe é conferido. Entretanto, somente a cooperação entre os órgãos de saúde pública e o sistema penitenciário pode produzir resultados eficientes.

ABSTRACT

BACKGROUND: Cytomegalovirus (HCMV) has been described in abortion tissues, but seldom associated with inclusion bodies. However, the possible pathogenic role of this virus in abortion is under discussion. We attempted to verify the relationship between HCMV antigens in tissues from first trimester abortions presenting with inflammatory lesions. MATERIAL/METHODS: Sixteen cases of first trimester abortions with inflammatory lesions were selected from 340 cases studied at the Pathology Unit of the University Hospital in Vit ria, Esp rito Santo State, Brazil. Paraffin-embedded sections were subjected to indirect immunofluorescence (IFI) and immunoperoxidase (PAP), using monoclonal antibodies directed against immediate early (IEA) and late antigens (LA) of HCMV. RESULTS: Twelve out of sixteen cases (75%) presented at least one HCMV antigen. Eight cases presented both antigens, three cases only the IEA and one case only the LA. These antigens were present in decidual cells, in stromal cells of chorionic villi and in trophoblastic cells. CONCLUSIONS: The results showed high frequency of HCMV antigens in tissues from first trimester abortion. This frequency, higher than that previously reported, was probably due to the fact that necro-inflammatory lesions were always present in selected cases. The presence of LA in trophoblastic cells is evidence for cell permissiveness to viral replication in vivo. The results showing high presence of HCMV antigens in tissues from abortion with inflammatory lesions suggest a possible relationship of HCMV infection with inflammation and pregnancy loss.

ABSTRACT

Relatamos um caso de trissomia completa do cromossomo 9 associada com aumento da translucência nucal (9,1 mm), diagnosticada por ultra-som na 12ª semana de gestação e confirmada por cariótipo em espécime de biópsia do vilo corial. Múltiplas anomalias congênitas foram diagnosticadas no exame ultrasonográfico e confirmadas na autópsia. Embora rara, a trissomia 9 deve ser incluída no rol das anomalias cromossômicas associadas com aumento da translucência nucal.
