Sexually transmitted infections among active component members of the U.S. Armed Forces, 2015-2023.

This report summarizes incidence rates and trends of sexually transmitted infections (STIs) from 2015 through 2023 among active component service members of the U.S. Armed Forces. The data compiled for this report are derived from the medical surveillance of chlamydia, gonorrhea, and syphilis as nationally notifiable diseases. Case data for 2 additional STIs, human papilloma virus (HPV) and genital herpes simplex virus (HSV), are also presented. The crude total case rates of chlamydia and gonorrhea initially rose by an average of 6.7% and 9.8% per year, respectively, until 2019. From 2020 onwards, rates steadily declined. By 2023, chlamydia rates had dropped by approximately 39%, while gonorrhea rates had fallen by more than 40% for female, and 19% for male, service members. Initially syphilis increased, on average, 10% annually from 2015 to 2019, then declined in 2020, but resumed its upward trend through 2023, nearly doubling the 2015 rate in 2023. The total crude annual incidence rates of genital HPV and HSV exhibited downward trends in general over the surveillance period, decreasing by 30.7% and 24.7%, respectively. Age- and gender-adjusted case rates for chlamydia, gonorrhea, and syphilis remain elevated within the U.S. Armed Forces compared to the general U.S. population, which may be due to factors that include mandatory STI screening, more complete reporting, incomplete adjustment for age distribution, and inequitable comparisons between the military active duty and general U.S. populations. Social restrictions enacted during the COVID-19 pandemic may have contributed to declines in true case rates and screening coverage.

Syphilis.

This is a case report of 51-year-old male patient with various symptoms including skin rashes, sensory disturbances, and non-cicatricial hair loss. Despite previous tests, the cause remained elusive until a dermatological examination revealed signs of syphilis. The patient's history, including his sexual relationships, became key in confirming the diagnosis, leading to treatment for neurosyphilis. With a rising incidence of syphilis in Denmark, this case highlights the importance of considering syphilis as a potential diagnosis across medical specialities because of the diverse and challenging clinical manifestations.

Serological markers of transfusion transmissible infections and ABO blood groups in Najran, Saudi Arabia.

OBJECTIVES: To ascertain the prevalence of transfusion transmissible infections (TTIs) across diverse donor groups in the Najran province. Additionally, to establish a potential association between the development of TTI and the donors' blood group, as determined by the ABO/Rh blood grouping system. METHODS: Blood donation data of 4120 donors, spanning from January to December 2020, were retrospectively reviewed. The blood were screened for TTI markers, including hepatitis B surface antigen (HBsAg), anti-hepatitis B core (anti-HBc), anti-hepatitis C virus (anti-HCV), anti-human immunodeficiency viruses 1 and 2 (anti-HIV1&2), anti-human T-lymphotropic virus types 1 and 2 (anti-HTLV-1&2), and syphilis antigen. RESULTS: Positive TTI markers were detected in 10.9% of the donors. The most detected TTI marker was anti-HBc (8.9%), followed by HBsAg (0.7%). Other markers were individually detected in <1% of the donors. Anti-HBc-positive was significantly elevated among non-Saudi blood donors. There was an association between age groups and anti-HCV (p=0.002), anti-HTLV (p=0.004) and syphilis antigen (p=0.02) markers positivity. The AB positive blood group exhibited the most positivity for TTI markers, followed by O positive blood group. Similarly, association was found between ABO group and HBsAg (p=0.01), anti-HBc (p=0.001), and anti-HCV (p<0.001) markers positivity. CONCLUSION: Emphasis on implementing robust screening measures for donated blood is underscored by this study. There is the need for future study to extensively evaluate TTI status to enhance our understanding of the trend in TTI.

Transfusion transmitted infections among blood donors of Kamenge Teaching Hospital blood bank in Burundi.

Background: The current risk of contracting a transfusion transmitted infections (TTIs) is unknown in Burundi. Objectives: The aim of this study was to assess sociodemographic profiles of blood bank donors at Kamenge Teaching Hospital, the prevalence and associated risk factors of HIV, syphilis, HBV and HCV from 2015 to 2020. Methods: We conducted a cross-sectional study including all blood donors of Kamenge Teaching Hospital blood bank. During this study, 1370 blood samples were screened for HIV, Syphilis, HBV and HCV. We calculated prevalence of TTIs and performed logistic regression to know associated risk factors. Results: Blood donors were males at 77% and 23% females. They were mostly students (54.2%). On screening, 83 blood samples (6.06%) were seropositive for at least one TTI. The overall prevalence rate of HIV, Syphilis, HBV and HCV among blood donors was 1.3%, 0.2% ,1.6%, 2.9% respectively. There was difference in distribution of the four TTIs among blood donors which is statistically significant (x2=33.997, ϱ-value<0.001). Private donors were associated with a high risk of syphilis and being a first-time donor was associated with a high HBV risk factor. Conclusion: The prevalence of TTIs found still to be high; mandatory and continuous screening is necessary.

Current syphilis infection in virally suppressed people living with HIV: a cross-sectional study in eastern China.

Background: Antiretroviral therapy (ART) has been shown to reduce human immunodeficiency virus (HIV) viral replication and ultimately achieve viral suppression and eliminate HIV transmission. However, little is known about the impact of viral suppression on high-risk behaviors and sexually transmitted infections (STIs). Objective: This study aimed to assess the rates of current syphilis infection in virally suppressed people living with HIV (PLWH) and whether with the duration of ART can reduce the current syphilis infection in eastern China. Method: We conducted a cross-sectional survey of PLWH in Zhejiang Province, China, in 2022. PLWH who were on ART >6 months and were virally suppressed (viral load <50 copies/mL) were included in the study. Data were collected from the National Epidemiological Database of Zhejiang Province and all participants were tested for viral load and current syphilis. Multivariable logistic regression was used to identify risk factors associated with current syphilis infection. Result: A total of 30,744 participants were included in the analysis. 82.7% of participants were male, the mean age was 44.9 ± 14.1 years, 84.9% had received ART in a hospital setting, the mean time on ART was 5.9 ± 3.1 years and 5.6% of participants were infected with current syphilis. Multivariable logistic regression showed that being male [adjusted odds ratio (aOR): 2.12, 95% confidence interval (CI): 1.69-2.66], high level of education (aOR: 1.23, 95% CI: 1.02-1.49), homosexual route of HIV infection (aOR: 1.80, 95% CI: 1.60-2.04), non-local registered residence (aOR: 1.29, 95% CI: 1.11-1.51), had history of STIs before HIV diagnosis (aOR: 1.95, 95 % CI: 1.75-2.18) and treatment provided by a municipal hospital (aOR: 2.16, 95% CI: 1.31-3.55) were associated with increased risk of current syphilis infection. Being married (aOR: 0.67, 95% CI: 0.58-0.76) was associated with a decreased risk of current syphilis infection. Conclusion: Our findings revealed a high rate of current syphilis infection among virally suppressed PLWH in eastern China. Duration of ART did not reduce the prevalence of current syphilis infection. Targeted interventions to reduce current syphilis infection should be prioritized for subgroups at higher risk.

Incidence and risk factors associated with acquired syphilis in HIV pre-exposure prophylaxis users.

BACKGROUND: Acquired syphilis continues to affect millions of people around the world. It is crucial to study it in the context of HIV Pre-Exposure Prophylaxis (PrEP) to achieve the goals set out in the 2030 Agenda since the literature suggests increased risk behaviors for sexually transmitted infections. This study aimed to investigate the incidence and factors associated with acquired syphilis among PrEP users. MATERIALS AND METHODS: This retrospective cohort included data on PrEP users from all over Brazil from 2018 to 2020, retrieved from the national antiretroviral logistics system. We calculated the proportion of syphilis before PrEP, the incidence during the user's follow-up, reinfections, and their possible associated factors. We conducted descriptive, bivariate, and multivariate analysis, estimating the crude Relative Risk, adjusted Odds Ratio (aOR), and their respective confidence intervals (95%CI). RESULTS: Most of the 34,000 individuals who started PrEP were male (89.0%), white (53.7%), self-identified as male (85.2%), homosexual, gay, or lesbian (72.2%), and had 12 schooling years or more (67.8%). Of these, 8.3% had syphilis in the six months before starting PrEP, and 4% had it in the first 30 days of using the prophylaxis. We identified a loss-to-follow-up rate of 41.7%, although the loss and the cohort shared similar characteristics. The proportion of missed syphilis tests was high: 33.4% in the 30 days and 38.8% in the follow-up period. In the 19,820 individuals effectively monitored, the incidence of acquired syphilis was 19.1 cases per 100 person-years, and 1.9% of users had reinfection. The rate of missed syphilis tests at the 30-day follow-up was 33.4%, and the total follow-up test period was 38.8%. The multivariate analysis identified female gender (aOR 0.3; 95%CI 0.2-0.5), being white or Black (aOR 0.9; 95%CI 0.7-0.9 and aOR 0.7; 95%CI 0.7-0.99, respectively) as protective factors for syphilis. Being homosexual, gay, lesbian (aOR 2.7; 95%CI 2.0-3.7), or having a history of syphilis in the six months before PrEP (aOR 2.2; 95%CI 1.9-2.5) were risk factors for syphilis during PrEP use. Behaviors related to the risk of syphilis included accepting something in exchange for sex (aOR 1.6; 95%CI 1.3-1.9), irregular condom use (use in less than half of sexual intercourse sessions; aOR 1.7; 95%CI 1.53-2.1) and recreational drug use (poppers; aOR 1.5; 95%CI 1.53-2.1). CONCLUSION: Syphilis in the context of PrEP has high rates and is associated with sociodemographic and behavioral factors. We recommend additional studies targeting prevention in this population to curb these figures.

[Syphilis infection and related factors among HIV-infected patients in Zhejiang Province].

Objective: To investigate syphilis infection and related factors among HIV-infected patients being followed up for more than one year in Zhejiang Province. Methods: Data were collected from the China Disease Control and Prevention Information System, and information such as demographic characteristics, viral load levels, and syphilis serologic test results was collected from HIV-infected persons who were diagnosed with HIV more than 1 year, aged ≥15 years with a current address in Zhejiang Province through December 31, 2022. The logistic regression model analyzed the prevalence of syphilis and the related factors. The SPSS 19.0 software was used for statistical analysis. Results: A total of 33 734 HIV-infected patients, with the prevalence of syphilis was 5.6% (1 879/33 734). Among the syphilis cases, the prevalence of syphilis was 6.4% (1 774/27 934) of males, 7.5% (640/8 543) of 25-34 years old age group, 7.6% (1 025/13 423) of unmarried, 8.3% (1 239/14 862) of homosexual transmission, 6.9% (214/3 080) with a non-local registered residence and 9.6% (602/6 267) with a history of STD before the HIV diagnosis. Multivariate Logistic regression analysis showed that participants who were male (aOR=2.19, 95%CI:1.77-2.72), 25-34 years old age group (aOR=1.80, 95%CI:1.47-2.20), homosexual transmission (aOR=1.67, 95%CI:1.49-1.88), with other provinces registered residence (aOR=1.26, 95%CI:1.09-1.47), and with a history of sexually transmitted disease (STD) before the HIV diagnosis (aOR=1.98, 95%CI:1.78-2.20) were associated with increased risk of syphilis. Being married (aOR=0.79, 95%CI:0.68-0.92) was associated with a decreased risk of syphilis. Conclusions: Syphilis infections were high in HIV-infected patients followed up more than one year in Zhejiang Province. It is recommended that syphilis surveillance and screening frequency should be strengthened among HIV-infected persons with characteristics such as male, homosexual transmission, and STD history.

Seroinfection of Antibodies to Toxoplasma gondii, Parvovirus B19, Treponema pallidum, and HIV in a Pregnant Attending a Medical Center in Northern Peru.

Introduction: Transplacental infections are frequent, especially in developing countries, where limited screening is performed to find infectious agents in the pregnant population. We aim to determine the clinical and epidemiological characteristics and seroinfection of antibodies against Toxoplasma, parvovirus B19, T. pallidum, and HIV in pregnant women who attended the Motupe Health Center in Lambayeque, Peru during July-August 2018. Methods: A descriptive cross-sectional study was conducted in 179 pregnant women interviewed with a standardized questionnaire. ELISA was used to determine antibodies to Toxoplasma and parvovirus B19. The detection of syphilis and HIV was conducted using immunochromatography, while the detection of hepatitis B was conducted using FTA-ABS and immunofluorescence, respectively. Results: Of 179 pregnant women, syphilis and HIV infections routinely included in the screening of pregnant women presented a seroinfection of 2.2 and 0.6%, respectively. Toxoplasmosis seroinfection was 25.1%, while IgM antiparvovirus B19 was 40.8%, revealing that pregnant women had an active infection at the time of study. Conclusion: The level of seroinfection of toxoplasmosis reveals the risk to which pregnant women who participated in the study are exposed. The high seroinfection of parvovirus B19 could explain the cases of spontaneous abortion and levels of anemia in newborn that have been reported in Motupe, Lambayeque, Peru. However, future causality studies are necessary to determine the significance of these findings.

Epidemiological characteristics of syphilis in mainland China, 2004 to 2019.

OBJECTIVES: Syphilis is a globally prevalent sexually transmitted infection. This study aimed to elucidate the epidemiological characteristics of syphilis in China from 2004 to 2019. METHODS: Incidence data for syphilis across 31 provinces in mainland China were obtained from the Data Center of China Public Health Science for the period from 2004 to 2019. Epidemiological methods and the Chi-squared test were used to analyze the temporal, regional, and disease stage distributions of syphilis. RESULTS: In total, 5,527,399 syphilis cases were reported in China from 2004 to 2019, with an average annual prevalence of 25.7063 per 100,000 population and overall increasing trend. In terms of regional distribution, high-incidence provinces included Shanghai, Zhejiang, Fujian, Guangxi, Guangdong, Xinjiang, Ningxia, and Qinghai. The proportion of latent syphilis increased from 20.41% in 2004 to 82.95% in 2019, with an upward trend each year. CONCLUSIONS: Syphilis incidence exhibited an overall increasing trend in China, and latent syphilis was predominant. Syphilis incidences considerably varied among regions, and syphilis was detected from coastal to inland provinces. Thus, syphilis prevention and control programs should be tailored according to the specific epidemiological characteristics of each region.

A Review of Syphilis Infection in Pediatric Patients.

Nearly half of all sexually transmitted infections occur in adolescents and young adults. Among them, syphilis infections are on the rise in the United States. Sexually active adolescents, especially those who do not use condoms consistently or are men who have sex with men, are at particular risk for syphilis infection. With the rise in acquired syphilis infections, the incidence of congenital syphilis has also increased. Syphilis can have a variety of presentations based on infectious stage and central nervous system involvement. Careful physical examination and history can elicit the diagnosis. Screening with a nontreponemal test followed by treponemal testing can confirm the diagnosis, and staging is determined clinically. Testing for all sexually transmitted infections should be pursued because coinfections are common. Penicillin is the first-line treatment for syphilis, and duration of therapy depends on the presence of neurologic symptoms; all infants with possible congenital syphilis should receive treatment. Posttreatment monitoring is essential to confirm successful eradication of syphilis. All sexually active, at-risk patients, including pregnant persons, should be screened for syphilis, and those diagnosed as having syphilis should be counseled on disclosure to partners. Although not often found in a pediatric population, with the increasing incidence of syphilis infections in the United States, pediatric providers should have a low threshold for syphilis screening in adolescents and a high index of suspicion for congenital syphilis in infants.

Relapsed Mpox Keratitis, St. Louis, Missouri, USA.

We describe a case of a 46-year-old man in Missouri, USA, with newly diagnosed advanced HIV and PCR-confirmed mpox keratitis. The keratitis initially resolved after intravenous tecovirimat and penicillin for suspected ocular syphilis coinfection. Despite a confirmatory negative PCR, he developed relapsed, ipsilateral PCR-positive keratitis and severe ocular mpox requiring corneal transplant.

Risk for Donor-Derived Syphilis after Kidney Transplantation, China, 2007-2022.

To evaluate the risk of acquiring syphilis from a donated kidney, we evaluated kidney transplantation pairs from West China Hospital, Sichuan, China, during 2007-2022. Donor-derived syphilis was rare. Risk may be higher if donors have active syphilis and may be reduced if recipients receive ceftriaxone.

Detection of gestational and congenital syphilis in Paraná state, Brazil, 2007-2021: a time series analysis.

OBJECTIVE: To describe temporal trends in the detection rates of gestational and congenital syphilis, by maternal age and health macro-region of the state of Paraná, Brazil, 2007-2021. METHODS: This was a time-series study using surveillance data; the trend analysis was performed by means of joinpoint regression, and average annual percent change (AAPC) and 95% confidence intervals (95%CI) were estimated. RESULTS: An increase in statewide detection of gestational syphilis (AAPC = 21.7; 95%CI 17.7; 32.8) and congenital syphilis (AAPC = 14.8; 95%CI 13.0; 19.7) was found; an increase was also found in the health macro-regions, with the Northwest (gestational, AAPC = 26.1; 95%CI 23.4; 31.6) and North (congenital, AAPC = 23.8; 95%CI 18.8; 48.9) macro-regions standing out; statewide rising trends were observed for young women [gestational, AAPC = 26.2 (95%CI 22.4; 40.6); congenital, AAPC = 19.4 (95%CI 17.6; 21.8)] and adult women [gestational, AAPC = 21.3 (95%CI 16.9; 31.9); congenital, AAPC = 13.7 (95%CI 11.9; 19.3)]. CONCLUSION: Maternal and child syphilis detection rates increased in the state, regardless of maternal age and health macro-region. MAIN RESULTS: Increasing trends were found for the detection rates of gestational and congenital syphilis in Paraná state and its health macro-regions, including in the analysis stratified by maternal age group; however, there was a decline during the COVID-19 period. IMPLICATIONS FOR SERVICES: There is a need for strategic and immediate action by the state health services, focusing on expanding access and linkage to care, in order to ensure maternal and child well-being and reverse the rising trends observed. PERSPECTIVES: Prevention and control actions towards the elimination of syphilis are needed to overcome these obstacles, directing efforts towards strengthening health education, early detection and appropriate treatment for pregnant women and their partners.

Prévalence de Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum et du VIH chez les femmes à Kara, en 2022.

OBJECTIVE OF THE STUDY: To estimate the prevalence of four STIs in women of reproductive age in the Kara region. METHODS: A cross-sectional study was conducted in March 2022. Data were collected using a standardized questionnaire. Screening for HIV and syphilis was performed using the SD-BIOLINE HIV/Syphilis Duo® rapid tests. The GeneXpert PCR technique was used to test for Chlamydia trachomatis and Neisseria gonorrhoeae. The prevalences of STIs (Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, and HIV) were reported with 95% confidence intervals. RESULTS: A total of 300 women with a median age of 32 years (interquartile range 24–39) were included. Of these, 25.7% had consulted a gynecologist in the last twelve months. The prevalence of Chlamydia trachomatis was 4.3% (95% CI [2.4–7.5]); Neisseria gonorrhoeae 3.3% [95% CI: 1.7–6.2], Treponema pallidum 0.3% [95% CI: 0.02–2.1] and HIV 3.7% [95% CI: 1.9–6.7]. Three cases of co-infection with Neisseria gonorrhoeae and Chlamydia trachomatis were reported; no cases of co-infection with HIV and bacterial STIs were reported. CONCLUSION: This study confirms the women’s limited access to gynecological consultations, the low circulation of syphilis, and the presence of Neisseria gonorrhoeae and Chlamydia trachomatis in women of reproductive age in the Kara region. An STI surveillance system is needed to improve STI management among this population.

Analysis of molecular subtypes and antibiotic resistance in Treponema pallidum isolates from blood donors in Khyber Pakhtunkhwa, Pakistan.

Syphilis, caused by Treponema pallidum, is resurging globally. Molecular typing allows for the investigation of its epidemiology. In Pakistan and other nations, T. pallidum subsp. pallidum has developed widespread macrolide resistance in the past decade. A study at the Peshawar Regional Blood Centre from June 2020-June 2021 analyzed serum samples from 32,812 blood donors in Khyber Pakhtunkhwa, Pakistan, to assess circulating T. pallidum strains and antibiotic resistance. Blood samples were initially screened for T. pallidum antibodies using a chemiluminescent microparticle immunoassay (CMIA). CMIA-reactive samples underwent polymerase chain reaction (PCR) targeted the polA, tpp47, bmp, and tp0319 genes. PCR-positive samples were further analyzed for molecular subtyping using a CDC-developed procedure and tp0548 gene examination. All PCR-positive samples were analyzed for the presence of point mutations A2058G and A2059G in 23S rRNA, as well as the G1058C mutation in 16S rRNA. These mutations are known to impart antimicrobial resistance to macrolides and doxycycline, respectively. Out of 32,812 serum samples, 272 (0.83%) were CMIA-reactive, with 46 being PCR-positive. Nine T. pallidum subtypes were identified, predominantly 14d/f. The A2058G mutation in 23S rRNA was found in 78% of cases, while G1058C in 16S rRNA and A2059G in 23S rRNA were absent. The research found donor blood useful for assessing T. pallidum molecular subtypes and antibiotic resistance, especially when chancres are not present. The prevalent subtype was 14d/f (51.85%), and the high macrolide resistance of 36 (78%) indicates caution in using macrolides for syphilis treatment in Khyber Pakhtunkhwa, Pakistan.

HIV, syphilis and sexual-risk behaviours' prevalence among in-and out-of-school adolescent girls and young women in Zambia: A cross-sectional survey study.

BACKGROUND: In Zambia, 3.8% of young women and men aged 15-24 are HIV positive. However, like in most developing nations, HIV prevalence is higher among young women than young men (5.6% versus 1.8%). Despite the recognition of the rights of young people to sexual reproductive health (SRH) information and services, adolescent and young people (AYP) still face challenges in accessing healthcare in public health institutions including access to comprehensive knowledge on HIV/AIDs, HIV testing and contraceptives. The overall objective of the study was to collect baseline HIV, SRH and gender based violence (GBV) data at district level to inform the design of interventions targeting adolescent girls and young women (AGYW) aged 10-24 years in 20 districts of Zambia. METHODS: A cross-sectional, mixed-methods study was conducted in 20 districts of Zambia with the highest incidence of HIV. Data was collected between August and October 2022 with a total response rate of 92% (12,813/13960), constituting 5979 (46.7%) in-school and 6834 (53.3%) out-of-school participants. RESULTS: Overall, Mwinilunga, Chinsali, Chisamba and Chembe districts had the highest number of respondents, while Sinazongwe and Mungwi districts contributed the least. The overall age distribution was such that 12.6% (n = 1617) of those interviewed were aged 10 to 14 years, 35.4% (n = 4536) were aged 15-19 years, and 52.0% (n = 6660) were aged 20-24 years. The overall mean age at first sex among AGYW interviewed was 16.6 years which was broken down as follows: 16.2 years for in-school and 16.8 years for out of school. Overall, most of the respondents had first time sex with either their boyfriend (80.4%) or husband (15.6%), with 2.4% of the in-school participants reporting to have had their sexual debut in marriage compared to 21.0% among out-of-school AGYW. Prevalence of HIV was higher in the out-of-school compared to the in-school participants (5.5% vs 2.0%), Similarly, the prevalence of syphilis was higher in the out-of-school than the in-school participants (4.1% vs 1.5%). CONCLUSION: The study focused on assessing the prevalence and vulnerability of HIV, syphilis, GBV, and SRH services uptake among adolescent girls and young women, and exploring factors affecting girls' stay-in-school and re-engagement. The study found that HIV and syphilis are still significant public health problems among adolescent girls and young women in Zambia, emphasizing the need for increased efforts to prevent and manage these infections.

Congenital syphilis, syphilis in pregnancy and prenatal care in Brazil: An ecological study.

The aim of this research was to evaluate the incidence of congenital syphilis and the ratio between congenital syphilis and syphilis in pregnant women in Brazil according to socioeconomic indicators (inadequate water supply and sanitation; illiteracy at 15 years of age or older; household income per capita; proportion of poor people; Gini index; human development index; and average health expenditure per inhabitant by the health system) and prenatal quality-of-care indicators. We conducted an ecological study using a sample composed of 257 municipalities, each with ≥ 100,000 inhabitants. Data was collected from four public databases: the Brazilian Institute of Geography and Statistics, comprising socioeconomical data from the 2010 census; and the data of 2019 available in the databases of the Department of Informatics of the Brazilian Health System, Information and Management of Primary Care, and the Electronic Citizen Information System. Descriptive analysis of dependent and independent variables and bivariate analysis by Negative Binomial regression were carried out. The mean incidence of congenital syphilis was 38% higher in municipalities with a Human Development Index up to 0.785 (ratio of means [RM] = 1.38; p = 0.049) and 57% higher among populations where less than 50% of primary healthcare services provided a rapid test for syphilis (RM = 1.57; p < 0.001). The ratio between congenital syphilis and syphilis in pregnant women was 29% higher in municipalities with a low household income per capita (RM = 1.29; p < 0.001) and 28% higher in locations where less than 50% of the primary healthcare services provided a rapid test for syphilis (RM = 1.28; p < 0.001). There was no statistical significance of the quality of prenatal care compared to the outcomes. This result underscores the challenges in detecting syphilis infections among pregnant women during prenatal care, consequently increasing the risk of vertical transmission of the disease to the fetus. Traits of inequality in the occurrence of congenital syphilis also draw attention to strategies to reduce health inequities and improve prenatal care.

Cost-effectiveness of interventions for HIV/AIDS, malaria, syphilis, and tuberculosis in 128 countries: a meta-regression analysis.

BACKGROUND: Cost-effectiveness analyses have been conducted for many interventions for HIV/AIDS, malaria, syphilis, and tuberculosis, but they have not been conducted for all interventions that are currently recommended in all countries. To support national decision makers in the effective allocation of resources, we conducted a meta-regression analysis of published incremental cost-effectiveness ratios (ICERs) for interventions for these causes, and predicted ICERs for 14 recommended interventions for Global Fund-eligible countries. METHODS: In the meta-regression analysis, we used data from the Tufts University Center for the Evaluation of Value and Risk in Health (Boston, MA, USA) Cost-Effectiveness Registries (the CEA Registry beginning in 1976 and the Global Health CEA registry beginning in 1995) up to Jan 1, 2018. To create analysis files, we standardised and mapped the data, extracted additional data from published articles, and added variables from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD). Then we selected ratios for interventions with a minimum of two published articles and three published ICERs that mapped to one of five GBD causes (HIV/AIDS, malaria, syphilis, drug-susceptible tuberculosis, or multi-drug resistant tuberculosis), and to a GBD country; reported a currency year during or after 1990; and for which the comparator intervention was defined as no intervention, standard of care, or placebo. Our meta-regression analysis used all available data on 25 eligible interventions, and quantified the association between ICERs and factors at country level and intervention level. We used a five-stage statistical model that was developed to synthesise evidence on cost-effectiveness analyses, and we adapted it for smaller sample sizes by grouping interventions by cause and type (ie, prevention, diagnostics, and treatment). Using the meta-regression parameters we predicted country-specific median ICERs, IQRs, and 95% uncertainty intervals in 2019 US$ per disability-adjusted life-year (DALY) for 14 currently recommended interventions. We report ICERs in league tables with gross domestic product (GDP) per capita and country-specific thresholds. FINDINGS: The sample for the analysis was 1273 ratios from 144 articles, of which we included 612 ICERs from 106 articles in our meta-regression analysis. We predicted ICERs for antiretroviral therapy for prevention for two age groups and pregnant women, pre-exposure prophylaxis against HIV for two risk groups, four malaria prevention interventions, antenatal syphilis screening, two tuberculosis prevention interventions, the Xpert tuberculosis test, and chemotherapy for drug-sensitive tuberculosis. At the country level, ranking of interventions and number of interventions with a predicted median ICER below the country-specific threshold varied greatly. For instance, median ICERs for six of 14 interventions were below the country-specific threshold in Sudan, whereas 12 of 14 were below the country-specific threshold in Peru. Antenatal syphilis screening had the lowest median ICER among all 14 interventions in 81 (63%) of 128 countries, ranging from $3 (IQR 2-4) per DALY averted in Equatorial Guinea to $3473 (2244-5222) in Ukraine. Pre-exposure prophylaxis for HIV/AIDS for men who have sex with men had the highest median ICER among all interventions in 116 (91%) countries, ranging from $2326 (1077-4567) per DALY averted in Lesotho to $53 559 (23 841-108 534) in Maldives. INTERPRETATION: Country-specific league tables highlight the interventions that offer better value per DALY averted, and can support decision making at a country level that is more tailored to available resources than GDP per capita and country-specific thresholds. Meta-regression is a promising method to synthesise cost-effectiveness analysis results and transfer them across settings. FUNDING: Bill & Melinda Gates Foundation.

Doubts about the diagnosis and treatment of syphilis in pregnancy among primary care professionals in a telehealth service.

This cross-sectional study aims to describe doubts regarding the diagnosis and treatment of syphilis in pregnancy among primary care professionals in a telehealth service. All teleconsultations (TCs) offered through TelessaúdeRS-UFRGS to primary health care (PHC) services in the state of Rio Grande do Sul between 2018 and 2021 involving syphilis in pregnancy were included. A total of 356 (TCs) were analyzed. The main doubts about syphilis during pregnancy raised by primary care professionals were related to the need for retreatment (35%), diagnostic definition (23%) and initial treatment (16%). In addition, 95% of TCs were suitable for diagnosing and treating syphilis based on the 2020 Brazilian Ministry of Health guideline. This study suggests that TCs can identify failures in the diagnosis and treatment of public health problems and support decision making in PHC involving syphilis in pregnancy.
