Objective:
This systematic review accompanied by a meta-analysis aimed to estimate the prevalence of syphilis in pregnant women in Brazil and describe its associated factors.
Methods:
Following the establishment the search strategies and the registration of the review protocol in PROSPERO, we conducted a search for relevant articles in the Pubmed, LILACS, Science Direct, SciELO and Web of Science databases. Our inclusion criteria were cross-sectional studies published between 2005 and 2023, with no language restrictions. The combined prevalence of syphilis infection was estimated using the random effects model in the R Software with a 95% confidence interval (95% CI) and p < 0.01 as statistically significant.
Results:
A total of 24 articles were recruited, which together investigated 221,884 women. The combined prevalence of syphilis in pregnant women in Brazil was 1.79% (95% CI: 1.24-2.57%), and the main factors associated with its occurrence were black and brown skin color, low education and factors related to the partner.
Conclusion:
There was a high prevalence of syphilis in pregnancy in Brazil, mainly associated with socioeconomic factors.

Objective
To evaluate the seroprevalence of positive markers for syphilis, human immunodeficiency virus (HIV) I and II, human T cell lymphotropic virus (HTLV) I and II, and hepatitis B and C among women undergoing in vitro fertilization (IVF).
Methods
We conducted a retrospective analysis among patients who underwent IVF, between January 2013 and February 2016, and who had complete screening records.
Results
We analyzed 1,008 patients who underwent IVF, amounting to 2,445 cycles. Two patients (0.2%) tested positive for HIV I and II and none for HTLV I and II. Three patients (0.3%) had positive screening for syphilis, and two (0.2%) had positive hepatitis C antibody test (anti-HCV). A positive hepatitis B virus surface antigen (HbsAg) test was observed in 4 patients (0.4%), while 47 (4.7%) patients were positive for IgG antibody to hepatitis B core antigen (anti-HbC IgG), and only 1 (0.1%) was positive for IgM antibody to hepatitis B core antigen (anti-HbC IgM). The anti-HbS test was negative in 659 patients (65.3%). Only 34.7% of the patients had immunity against the Hepatitis B virus. Patients with an anti-HbS negative result were older than those with a hepatitis B test (anti-HbS) positive result (36.3 versus 34.9; p<0.001).
Conclusion
The present study showed lower infection rates than the Brazilian ones for the diseases studied in patients undergoing IVF. Only a few patients were immunized against hepatitis B.

Objective:
The present study assessed epidemiological and obstetrical data from pregnant women with syphilis at the Hospital de Clínicas of the Universidade Federal do Triângulo Mineiro (UFTM, in the Portuguese acronym), describing this disease during pregnancy and its vertical transmission for future healthcare actions.
Methods:
Records from pregnant women who had been admitted to the Obstetrics Department of the Hospital de Clínicas of the UFTM and were diagnosed with syphilis between 2007 and 2016 were reviewed. A standardized form was used to collect epidemiological, obstetric data and outcomes of congenital infection. The present research has been authorized by the Ethics Committee of the institution.
Results:
There were 268 women diagnosed with syphilis, with an average age of 23.6 years old. The majority of the patients were from Uberaba. Inadequate prenatal care was observed in 37.9% of the pregnant women. Only 34.2% of the patients completed the treatment according to the guidelines issued by the Ministry of Health of Brazil, and 19.8% of the partners of the patients underwent adequate syphilis treatment; 37 (13.8%) couples (patients and partners) underwent correct treatment. Regarding the obstetric outcomes, 4 (1.5%) patients had a miscarriage and 8 (3.4%) had fetal losses (from the fetal loss group, 7 had no adequate treatment); 61 (25.9%) patients had premature births - this prematurity has been significantly correlated to inadequate or incomplete treatment in 49 (27.9%) patients, compared with 12 (13.0%) patients with premature births and adequate treatment (p = 0.006). The average live newborn weight was 2,840 g; 25.3% had a birth weight < 2,500 g; 74.2% had congenital syphilis, a data with heavy correlation to inadequate or incomplete prenatal care, prematurity, and low birth weight.
Conclusion:
Public awareness policies on adequate prenatal care, intensification of serological screening, and early treatment of syphilis are needed, considering the rise of cases diagnosed during gestation and its potentially preventable deleterious consequences related to congenital transmission.

Gestational syphilis is a prevalent disease in Brazil and other low and medium income countries. Desensitization to penicillin is recommended for pregnant women with syphilis who are allergic to β-lactams. This is a descriptive study utilizing outpatient medical records from 2011 to 2015 from a mother and child hospital that is part of the national healthcare system in the South of Brazil, which performs an average of 3,600 birth assistances per year. All cases of pregnant women with syphilis and presumptive diagnosis of β-lactam allergy during the study period were included. The patients referred for desensitization originated from the hospital prenatal care service, as well as from municipal/state antenatal care services. Oral desensitization was performed in the obstetric emergency room, and adult and pediatric intensive care units were available at all times. Ten patients underwent desensitization during the period of study. Personal history of urticaria was the most common reaction that demanded desensitization. All patients tolerated the procedure well, and showed no adverse reactions.We report a successful program of oral desensitization. None of the patients presented adverse reactions or complications, a fact that corroborates the feasibility and safety of the desensitization protocol. Oral administration of penicillin comes at a low cost, and optimizes the use of time and resources.

Objective
To assess the knowledge and compliance of health professionals regarding the diagnostic and treatment practices for syphilis in patients admitted for childbirth in public maternity hospitals in the city of Teresina, in the state of Piauí, Northeastern Brazil.
Methods
A cross-sectional study was performed in 2015 with obstetricians and nurses working in the public maternity hospitals in Teresina (n = 159) using a selfadministered questionnaire, with 5% of losses and 10% of refusals. The study used 21 evaluation criteria: 13 of them were related to knowledge (5 on serological tests and 8 on treatment adequacy); 8 were related to practices (3 on diagnosis, 4 on treatment, and 1 on post-test counseling). The knowledge of and compliance to the practices was estimated as the proportion of health professionals’ answers that were in agreement with Brazilian Ministry of Health protocols.
Results
The obstetricians were in agreement with twocriteria concerning the knowledge of serological tests, one for diagnostic practices, and one for treatment practice. Among nurses, no single match between actual procedures and guidelines was observed.
Conclusions
Low compliance with the protocols results in missed opportunities for the diagnosis and treatment of pregnant and postpartum women and their partners. Strategies for training and integrating the various professional groups, improved data recording on prenatal cards, and greater accountability of the hospital team in managing the women’s partners are needed to overcome the barriers identified in the study and to interrupt the syphilis transmission chain.

Purpose
To evaluate maternal-fetal surveillance and follow-up of infants at risk for congenital syphilis (CS).
Methods
Retrospective cohort study in a Portuguese Tertiary Referral Hospital. The main inclusion criterion was a positive syphilis serology. The study included all pregnant women that delivered in our hospital between January 2004 and December 2013. The neonates were classified according to their probability of infection based on the Centers for Disease Control and Prevention guidelines.
Results
Among the 27 pregnancies at risk for CS, 48.2% (n = 13) of the women had a diagnosis during the 1st trimester, and the median gestational age at the end of the treatment was 28 weeks. Inadequate treatment was noted in 44.4% (n = 12) of the women. Adverse pregnancy outcomes were observed in 30.8% of the cases (n = 8), 5 of which had been adequately treated. We found 2 (7.7%) cases with “proven or highly probable CS,” 10 (38.5%) with “possible CS,” 12 (46.1%) with “less likely CS,” and 2 (7.7%) with “unlikely CS.”Among the infants, the treatment was successful, except for 1 neurosyphilis case.
Conclusion
This study highlights many of the difficulties/concerns encountered in the maternal-neonatal management of syphilis. We highlight the importance of assuring the early detection of the infection as a way of guaranteeing the timely treatment, as well as a good compliance to the treatment and follow-up through a more efficient pregnant women surveillance network.

METHODS: Quantitative study with data collected from May to October, 2008 at five public maternities in Fortaleza, Ceará. A survey was carried out with parturients who were hospitalized with syphilis and had a stable sex partner. We analyzed sociodemographic variables and those related to communication, diagnosis and treatment of sex partners. The data were entered into the Statistical Package for the Social Sciences and were analyzed using frequency distributions, measures of central tendency and dispersion. RESULTS: The study included 56 pregnant women. Most sexual partners were young adults aged on average 29 years, 50% of them had studied for less than seven years, 82.1 worked and 46.4% had a family income of less than a minimum wage. Of all the partners, 92.9% were the child's father and 69.6% lived with the women. Fifty percent and 12% were alcohol and drug users, respectively. Most partners (75.0%) were told about the diagnosis by the women, and in 78.6% of cases they were aware of the VDRL result before or during the prenatal period. However, 25.0% of the women did not communicate the result to their partners for the following reasons: not knowing the importance of the partner's treatment (50.0%), not being together after the diagnosis (42.9%) and having a quarrel (7.1%). Of the partners who were informed about the result before or during the prenatal period, 56.0% were treated and six (42.8%) were considered to have been properly treated. Among the ones who did not receive treatment, 63.6% refused it because they did not feel sick, because they did not believe in the treatment and because they were afraid of injections. CONCLUSIONS: Partners are told about the syphilis diagnosis of the pregnant women; however, only a few are properly treated.

Views73See moreA retrospective study examining medical records of female prostitutes attending the STD/AIDS Reference Center in Vitória, Brazil from January/93 to December/96 was conducted. During this period, 180 women received medical and psychological care in this clinic. Mean age was 25.9 year (SD=6.8). Out of 180, 140 agreed to be tested for HIV, of whom 12 (8.6%) had a positive result. Among 157 women who agreed to be tested for syphilis, 144 (91.7%) had a negative result, while 13 (8.3%) had a positive one. According to the educational degree, 6 (3.3%) women were illiterate, 114 (63.3%) attended elementary school, 37 (20.6%) attended secondary school, 7 (3.9%) went to college and 16 gave no information. One hundred and forty-one patients (78.3%) were single, 17 (9.4%) married, 10 (5,5%) divorced and 4 (2.2%) widows. The frequency of condom use was: always, 56 (31.3%), sometimes, 93 (52.0%), and 30 (16.8%) never used condoms. Other STDs were reported by 89 (49.4%) women and 9 (5.0%) reported intravenous (IV) drug use. There was a significant difference between the HIV positive and the negative group only regarding IV drug abuse (p=0.031) and syphilis infection (p=0.014). The present study showed prevalence rates of HIV infection among prostitutes in Vitória much higher than those found in the general population. There is a pressing need to improve medical assistance and educational campaigns especially designed to reach this population of women, and focusing the importance of regular condom use and the risks associated with IV drug abuse.
