    Abstract Abstract Pelvic Inflammatory Disease is a topic included in the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. Pelvic inflammatory disease is an upper female genital tract acute infection due to canalicular spread of endogenous cervicovaginal microorganisms and especially the sexually transmitted microorganisms. Standing out among the etiological agents involved are Chlamydia trachomatis and Neisseria gonorrhoeae. The main sequelae are chronic pelvic pain, infertility, and ectopic pregnancy. Clinical diagnosis is the most important practical approach. Antibiotic treatment must start immediately after the clinical suspicion. Guidelines for health service managers and health professionals on diagnostic tests, treatment, follow-up, counseling, notification, handling sexual partners and special populations are described. Given the increased availability of the molecular biology techniques in Brazil, C. trachomatis and N. gonorrhoeae screening are recommended as a disease prevention strategy.

    Abstract Resumo O tema doença inflamatória pélvica está contemplado no Protocolo Clínico e Diretrizes Terapêuticas para Atenção Integral às Pessoas com Infecções Sexualmente Transmissíveis, publicado pelo Ministério da Saúde do Brasil em 2020. A doença inflamatória pélvica é a infecção aguda do trato genital superior feminino decorrente da ascensão canalicular de microrganismos cervicovaginais endógenos e, principalmente, os de transmissão sexual. Entre os agentes etiológicos envolvidos, destacam-se Chlamydia trachomatis e Neisseria gonorrhoeae. As sequelas mais importantes são dor pélvica crônica, infertilidade e gravidez ectópica. O diagnóstico clínico apresenta-se como a abordagem prática mais importante. O tratamento com antibióticos deve ser iniciado imediatamente diante da suspeição clínica. Descrevem-se orientações para gestores e profissionais de saúde sobre testes diagnósticos, tratamento preconizado, seguimento, aconselhamento, notificação, manejo de parcerias sexuais e de populações especiais. Com a maior disponibilidade da técnica de biologia molecular no Brasil, recomenda-se o rastreio de C. trachomatis e N. gonorrhoeae como estratégia preventiva da doença.

    Abstract Background The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the possible development of serious illness, and the possibility of severe obstetric outcomes highlight the importance of addressing SARS-CoV-2 infection in obstetric management. Methods and findings A cross-sectional study of pregnant women assisted in a high-risk maternity hospital in Brazil in 2020. All patients admitted for delivery or miscarriage care were tested for SARS-CoV-2 using polymerase chain reaction (PCR) and for immunoglobulin (I)gM, and/or IgG by immunochromatography. Clinical aspects and obstetric outcomes were analyzed. A total of 265 pregnant women were included in the study. There were 38 (14.4%) PCR positive cases during pregnancy, 12 (31.6%) on admission screening, and 71(27.2%) patients were IgM- and/or IgG-positive. Among the participants, 86 (32.4%) had at least one positive test during pregnancy. SARS-CoV-2 positive patients had greater contact with known positive patients (p = 0.005). The most frequently reported symptoms were runny nose, cough, loss of smell and taste, headache, and fever. There was also a 35% rate of asymptomatic infections and a 4.6% rate of severe or critical infections. Patients exposed or infected with SARS-CoV-2 had a higher incidence of preterm delivery, cesarean section, need for resuscitation in the delivery room, Apgar score <7 at 5 min, admission to the neonatal intensive care unit, and jaundice. Newborns with at least one positive test had a significantly greater need for phototherapy after delivery (p = 0.05). The results showed a high rate of positive tests among newborns (37.5%), which seems to be compatible with both neonatal and perinatal infection. Conclusions It is important to further investigate SARS-CoV-2 infection during pregnancy, including the clinical course and the possibility of adverse outcomes with impact on maternal and fetal health, regardless of the development of symptoms.

    Abstract ABSTRACT There are few data on the impact of COVID-19 in pregnancy, however, analyzing these data is important to guide the clinical practice, covering the early prevention, detection, patients’ isolation, epidemiological investigation, diagnosis and early treatment. This is a report of three cases of COVID-19 confirmed by real-time reverse transcription – polymerase chain reaction (RT-PCR) of nasopharyngeal secretions collected in swabs from pregnant women in the city of Vitoria, Espirito Santo State, Brazil. In the three cases, all the patients presented with fever, one had shortness of breath, one had diarrhea, two of them reported abdominal pain and two of them had cough. The three patients progressed with a severe clinical evolution of COVID-19. The permanence in the intensive care unit (ICU) was more than 10 days. Two of them recovered and one remained in the ICU with irreversible refractory shock, multiple organ failure and died. The mode of delivery was individualized and based on the obstetric indication and severity of the maternal infection, and the cesarean section was indicated in the two severe maternal COVID-19 cases that evolved favorably. These newborns were premature and tested negative for COVID-19 by RT-PCR.

    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 ...

    Abstract Human Immunodeficiency Virus (HIV)-seropositive women are more likely to have anogenital cancer, and high risk-HPV (HR-HPV) infection is the main associated factor. Between August 2013 and December 2015, we conducted a descriptive study to determine the HPV genotypes and HPV16 variants in cervical and anal samples of HIV-seropositive women with a normal Pap test. The viral DNA was amplified by PCR using the PGMY09/11 set of primers. Reverse line blot (RLB), restriction fragment length polymorphism (RFLP) and sequencing assays were used to determine the HPV genotypes. HPV16 variants were identified by gene sequencing. We found a high frequency of HR-HPV (60.3%; 76/126) at the anogenital site among HIV-seropositive women and without association with anal intercourse. HPV16 and European variant predominated among the HR-HPV. Mixed infections with at least three different HPV types were common, particularly at the anal site. CD4+ T-cell counts below 500 cells/mm3, a HIV viral load above 50 copies/mL and an age of 18 to 35 years old were all related to HPV anal infection. Our study showed a high frequency of HR-HPV in both cervical and anal sites of women with negative cytology belonging to a risk group for the development of anogenital cancer.

    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 ...

    Abstract HPV16 accounts for 50-70% of cervical cancer cases worldwide. Characterization of HPV16 variants previously indicated that they differ in risks for viral persistence, progression to cervical precancer and malignant cancer. The aim of this study was to examine the association of severity of disease with HPV16 variants identified in specimens (n = 281) obtained from a Cervical Pathology and Colposcopy outpatient clinic in the University Hospital of Espírito Santo State, Southeastern Brazil, from April 2010 to November 2011. All cytologic and histologic diagnoses were determined prior to definitive treatment. The DNA was isolated using QIAamp DNA Mini Kit and HPV was detected by amplification with PGMY09/11 primers and positive samples were genotyped by RFLP analyses and reverse line blot. The genomes of the HPV16 positive samples were sequenced, from which variant lineages were determined. Chi2 statistics was performed to test the association of HPV16 variants between case and control groups. The prevalence of HR-HPV types in <CIN1, CIN2 and CIN3+ were 33.7%, 84.4% and 91.6%, respectively. Thirty-eight of 49 (78%) HPV16 positive samples yielded HPV16 sequence information; of which, 32 complete genomes were sequenced and an additional 6 samples were partially sequenced. Phylogenetic analysis and patterns of variations identified 65.8% (n = 25) as HPV16 European (E) and 34.2% (n = 13) as non-European (NE) variants. Classification of disease into CIN3+ vs. <CIN3 indicated that NE types were associated with high-grade disease with an OR = 4.6 (1.07-20.2, p = 0.05). The association of HPV16 NE variants with an increased risk of CIN3+ is consistent with an HPV16 genetically determined enhanced oncogenicity. The prevalence of genetic variants of HPV16 is distributed across different geographical areas and with recent population admixture, only empiric data will provide information on the highest risk HPV16 variants within a given population.<br />
