Routine Pharyngeal Gonorrhea Test-of-Cure: Is It An Effective Cephalosporin-Resistant Gonorrhea Control Strategy?
Quilter LAS , Horowitz R , Hall K , Bardier C , Bell J , Bergstrom AA , Beverley J , Cohen SE , Coleman M , Devlin S , Harold R , Harris M , Kamis K , Khurana R , Kohn R , Mettenbrink C , Nishiyama M , Sankaran M , Takai B , Velasquez C , Wendel KA , Bachmann LH , Barbee L . Sex Transm Dis 2025 BACKGROUND: Centers for Disease Control and Prevention recommends test-of-cure (TOC) for persons with pharyngeal gonorrhea (GC) 7-14 days after treatment. We investigated the yield and feasibility of routine pharyngeal GC TOC to detect treatment failures. METHODS: During May 2021-July 2022, four U.S. STD clinics implemented pharyngeal GC TOC. Sites collected demographic, clinical, and behavioral data on all treated pharyngeal GC and positive TOC cases. Cases were dispositioned with the suspected reason for positive TOC. To assess perceived feasibility, sites participated in qualitative interviews. RESULTS: During the study period, 1,968 pharyngeal GC infections were diagnosed. Among 1,829 treated cases, 97.3% (n = 1,777) received ceftriaxone and 45.7% (n = 836) returned for TOC, varying by site (range: 35.5%- 70.8%). Among those with TOC, 4.7% (n = 39) were positive by NAAT. Of these, 48.7% had culture attempted; six positive TOC (15.4%) were also positive by culture. Most positive TOC (66.7%) were attributed to re-infection (n = 13) or false-positive results (n = 13). Six (15.4%) were treatment failures. Four failed recommended treatment and had a positive culture: two were susceptible to ceftriaxone and two did not have antimicrobial susceptibility results. Seven positive TOC (17.9%) had insufficient data to disposition. Sites perceived TOC to be feasible, though substantial resources were required.ConclusionRoutine pharyngeal GC TOC yielded 5% positivity, though treatment failure was rare (<1%), and no cases of cephalosporin-resistant GC were identified. Low TOC return rates, limited culture collection, and limited culture yield highlight challenges to determining the cause of a positive TOC and the limitations of TOC in identifying cephalosporin resistance. |
FDA, CDC, and NIH Co-sponsored Public Workshop Summary-Development Considerations of Antimicrobial Drugs for the Treatment of Gonorrhea

Clin Infect Dis 2024 There is an unmet need for developing drugs for the treatment of gonorrhea, due to rapidly evolving resistance of Neisseria gonorrhoeae against antimicrobial drugs used for empiric therapy, an increase in globally reported multidrug resistant cases, and the limited available therapeutic options. Furthermore, few drugs are under development. Development of antimicrobials is hampered by challenges in clinical trial design, limitations of available diagnostics, changes in and varying standards of care, lack of robust animal models, and clinically relevant pharmacodynamic targets. On April 23, 2021, the U.S. Food and Drug Administration; Centers for Disease Control and Prevention; and National Institute of Allergy and Infectious Diseases, National Institutes of Health co-sponsored a workshop with stakeholders from academia, industry, and regulatory agencies to discuss the challenges and strategies, including potential collaborations and incentives, to facilitate the development of drugs for the treatment of gonorrhea. This article provides a summary of the workshop. |
Should we be testing for Mycoplasma genitalium on initial presentation? Trends in persistent/recurrent urethritis among men presenting for care in STD clinics, 2015-2019, STD Surveillance Network (SSuN)
Llata E , Tromble E , Schumacher C , Huspeni D , Asbel L , Pathela P , Kohn R , Kerani RP , Barbee L , Bachmann L . Sex Transm Dis 2024 51 (7) 493-498 BACKGROUND: Mycoplasma genitalium is a major contributor to persistent/recurrent urethritis cases. However, there are limited published studies on recent trends of persistent/recurrent urethritis. METHODS: A retrospective analysis was conducted of men presenting with symptomatic urethritis in 16 sexually transmitted disease (STD) clinics from 2015 to 2019. Poisson regression was used to assess trends in the annual proportions of urethritis episodes with follow-up (FU) characterized with persistent/recurrent urethritis symptoms. Results were also stratified by results of chlamydia (CT) and gonorrhea (NG) testing and treatment prescribed. RESULTS: There were 99,897 urethritis episodes, from 67,546 unique men. The proportion of episodes with persistent/recurrent symptomatic FU visits increased 50.8% over a 4-year period (annual percentage change [APC], 11.3%; 95% confidence interval [CI], 6.5-16.3). Similar trends were observed in nonchlamydial nongonococcal urethritis episodes (APC, 12.7%; 95% CI, 6.8-18.9) but increases among those positive for NG (APC, 12.1%; 95% CI, -2.3 to -28.5) or for CT (APC, 7.3%; 95% CI, -6.7 to 23.5) were not statistically significant. Among episodes who received azithromycin as first-line treatment, increases in the proportion of persistent/recurrent FU visits were observed (APC, 12.6%; 95% CI, 8.6-16.7). For episodes where first-line treatment was doxycycline, no significant increases were detected (APC, 4.3%; 95% CI, -0.3 to 9.2). CONCLUSIONS: We found an increase in the proportion of urethritis episodes with persistent or recurrent symptoms over time. Given these observed trends in episodes negative for NG or CT, an etiology not detectable by routine diagnostics was a likely factor in increased persistence, suggesting patients with urethritis may benefit from diagnostic testing for M. genitalium during an initial symptomatic presentation. |
Vaccine value profile for herpes simplex virus
Johnston C , Scheele S , Bachmann L , Boily MC , Chaiyakunapruk N , Deal C , Delany-Moretlwe S , Lee S , Looker K , Marshall C , Mello MB , Ndowa F , Gottlieb S . Vaccine 2024 Herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) are chronic, highly prevalent viral infections that cause significant morbidity around the world. HSV-2 is sexually transmitted and is the leading cause of genital ulcer disease (GUD). It also increases the risk of HIV acquisition, fueling the HIV epidemic. HSV-1 is typically acquired in childhood through nonsexual contact and contributes to oral and ocular disease, but it can also be sexually transmitted to cause GUD. Both HSV-1 and HSV-2 cause neonatal herpes and neurologic disease. Given the ubiquitous nature of HSV-1 and HSV-2 infections and the limited existing prevention and control measures, vaccination would be the most efficient strategy to reduce the global burden of morbidity related to HSV infection. Vaccine strategies include prophylactic vaccination, which would prevent infection among susceptible persons and would likely be given to adolescents, and therapeutic vaccinations, which would be given to people with symptomatic genital HSV-2 infection. This document discusses the vaccine value profile of both types of vaccines. This ‘Vaccine Value Profile’ (VVP) for HSV is intended to provide a high-level, holistic assessment of the information and data that are currently available to inform the potential public health, economic and societal value of pipeline vaccines and vaccine-like products. This VVP was developed by subject matter experts from academia, non-profit organizations, government agencies and multi-lateral organizations. All contributors have extensive expertise on various elements of the HSV VVP and collectively aimed to identify current research and knowledge gaps. The VVP was developed using only existing and publicly available information. © 2024 The Authors |
CDC clinical guidelines on the use of doxycycline postexposure prophylaxis for bacterial sexually transmitted infection prevention, United States, 2024
Bachmann LH , Barbee LA , Chan P , Reno H , Workowski KA , Hoover K , Mermin J , Mena L . MMWR Recomm Rep 2024 73 (2) 1-8 No vaccines and few chemoprophylaxis options exist for the prevention of bacterial sexually transmitted infections (STIs) (specifically syphilis, chlamydia, and gonorrhea). These infections have increased in the United States and disproportionately affect gay, bisexual, and other men who have sex with men (MSM) and transgender women (TGW). In three large randomized controlled trials, 200 mg of doxycycline taken within 72 hours after sex has been shown to reduce syphilis and chlamydia infections by >70% and gonococcal infections by approximately 50%. This report outlines CDC's recommendation for the use of doxycycline postexposure prophylaxis (doxy PEP), a novel, ongoing, patient-managed biomedical STI prevention strategy for a selected population. CDC recommends that MSM and TGW who have had a bacterial STI (specifically syphilis, chlamydia, or gonorrhea) diagnosed in the past 12 months should receive counseling that doxy PEP can be used as postexposure prophylaxis to prevent these infections. Following shared decision-making with their provider, CDC recommends that providers offer persons in this group a prescription for doxy PEP to be self-administered within 72 hours after having oral, vaginal, or anal sex. The recommended dose of doxy PEP is 200 mg and should not exceed a maximum dose of 200 mg every 24 hours.Doxy PEP, when offered, should be implemented in the context of a comprehensive sexual health approach, including risk reduction counseling, STI screening and treatment, recommended vaccination and linkage to HIV PrEP, HIV care, or other services as appropriate. Persons who are prescribed doxy PEP should undergo bacterial STI testing at anatomic sites of exposure at baseline and every 3-6 months thereafter. Ongoing need for doxy PEP should be assessed every 3-6 months as well. HIV screening should be performed for HIV-negative MSM and TGW according to current recommendations. |
Summary of the Centers for Disease Control and Prevention/National Institute of Allergy and Infectious Diseases Joint Workshop on Genital Herpes: 3-4 November 2022
Connolly KL , Bachmann L , Hiltke T , Kersh EN , Newman LM , Wilson L , Mena L , Deal C . Open Forum Infect Dis 2024 11 (5) ofae230 Genital herpes is caused by infection with herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and currently has no cure. The disease is the second-most common sexually transmitted infection in the United States, with an estimated 18.6 million prevalent genital infections caused by HSV-2 alone. Genital herpes diagnostics and treatments are not optimal, and no vaccine is currently available. The Centers for Disease Control and Prevention and the National Institute of Allergy and Infectious Diseases convened a workshop entitled "CDC/NIAID Joint Workshop on Genital Herpes." This report summarizes 8 sessions on the epidemiology of genital herpes, neonatal HSV, HSV diagnostics, vaccines, treatments, cures, prevention, and patient advocacy perspective intended to identify opportunities in herpes research and foster the development of strategies to diagnose, treat, cure, and prevent genital herpes. |
Syphilis complicating pregnancy and congenital syphilis
Stafford IA , Workowski KA , Bachmann LH . N Engl J Med 2024 390 (3) 242-253 Congenital syphilis, first described by Gaspar Torella in 1497, results primarily from the transplacental passage of Treponema pallidum and continues to cause major negative consequences worldwide.1 After a steady decline in U.S. cases of primary and secondary syphilis after 1990, which led to hopes of its elimination, rates hit a nadir in 2001. Unfortunately, the rates have subsequently increased among men and women of reproductive age, as well as infants, and in 2021, the rate of congenital syphilis in the United States was the highest it has been in nearly 30 years.2 |
Vital signs: Missed opportunities for preventing congenital syphilis - United States, 2022
McDonald R , O'Callaghan K , Torrone E , Barbee L , Grey J , Jackson D , Woodworth K , Olsen E , Ludovic J , Mayes N , Chen S , Wingard R , Johnson Jones M , Drame F , Bachmann L , Romaguera R , Mena L . MMWR Morb Mortal Wkly Rep 2023 72 (46) 1269-1274 INTRODUCTION: Congenital syphilis cases in the United States increased 755% during 2012-2021. Syphilis during pregnancy can lead to stillbirth, miscarriage, infant death, and maternal and infant morbidity; these outcomes can be prevented through appropriate screening and treatment. METHODS: A cascading framework was used to identify and classify missed opportunities to prevent congenital syphilis among cases reported to CDC in 2022 through the National Notifiable Diseases Surveillance System. Data on testing and treatment during pregnancy and clinical manifestations present in the newborn were used to identify missed opportunities to prevent congenital syphilis. RESULTS: In 2022, a total of 3,761 cases of congenital syphilis in the United States were reported to CDC, including 231 (6%) stillbirths and 51 (1%) infant deaths. Lack of timely testing and adequate treatment during pregnancy contributed to 88% of cases of congenital syphilis. Testing and treatment gaps were present in the majority of cases across all races, ethnicities, and U.S. Census Bureau regions. CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Addressing missed opportunities for prevention, primarily timely testing and appropriate treatment of syphilis during pregnancy, is important for reversing congenital syphilis trends in the United States. Implementing tailored strategies addressing missed opportunities at the local and national levels could substantially reduce congenital syphilis. |
Safety of longer-term doxycycline use: A systematic review and meta-analysis with implications for bacterial STI chemoprophylaxis
Chan PA , Le Brazidec DL , Becasen JS , Martin H , Kapadia J , Reno H , Bachmann L , Barbee LA . Sex Transm Dis 2023 50 (11) 701-712 BACKGROUND: Sexually transmitted infections (STIs) such as syphilis, gonorrhea, and chlamydia have significantly increased over the past decade in the United States. Doxycycline as chemoprophylaxis (i.e., post-exposure prophylaxis [PEP]) offers promise for addressing bacterial STIs. The goal of the current study was to evaluate the safety of longer-term doxycycline use (defined as eight or more weeks) in the context of potential use as STI chemoprophylaxis through a systematic literature review and meta-analysis. METHODS: This review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to search MEDLINE/PubMed for clinical studies published from August 2003 through January 2023 that reported on adverse events with doxycycline use with a focus on side-effects and metabolic effects of long-term use. RESULTS: A total of 67 studies were included in the systematic review. Overall, studies on longer-term doxycycline use reported 0% to over 50% adverse events ranging from mild to severe. Most common adverse events included gastrointestinal symptoms (i.e., nausea, vomiting, and abdominal pain), dermatologic (i.e., rash), and neurological (i.e., headache and dizziness) symptoms. Discontinuation of doxycycline due to adverse events was relatively uncommon in most studies. A meta-analysis of placebo controlled clinical trials (N = 18) revealed gastrointestinal and dermatological adverse events were more likely to occur in the doxycycline group. CONCLUSION: Longer-term (8+ weeks) doxycycline use is generally safe and may be associated with minor side-effects. Further research is needed on the potential metabolic impact of longer-term doxycycline use. |
Rising stillbirth rates related to congenital syphilis in the United States from 2016 to 2022
Machefsky A , Hufstetler K , Bachmann L , Barbee L , Miele K , O'Callaghan K . Obstet Gynecol 2024 OBJECTIVE: To identify trends in stillbirth rates attributed to congenital syphilis in the United States by describing congenital syphilis-related stillbirths and comparing characteristics of pregnant people who had congenital syphilis-related stillbirths with those of people who had preterm and full-term liveborn neonates with congenital syphilis. METHODS: Cases of congenital syphilis reported to the Centers for Disease Control and Prevention during 2016-2022 were analyzed and categorized as stillbirth, preterm live birth (before 37 weeks of gestation), or term live birth (37 weeks or later). Cases with unknown vital status or gestational age were excluded. Frequencies were calculated by pregnancy outcome, including pregnant person demographics; receipt of prenatal care; syphilis stage and titer; and timing of prenatal care, testing, and treatment. RESULTS: Overall, 13,393 congenital syphilis cases with vital status and gestational age were reported; of these, 853 (6.4%) were stillbirths. The number of congenital syphilis-related stillbirths increased each year (from 44 to 231); the proportion of congenital syphilis cases resulting in stillbirth ranged from 5.2% to 7.5%. Median gestational age at delivery for stillborn fetuses was 30 weeks (interquartile range 26-33 weeks). People with congenital syphilis-related stillbirths were more likely to have titers at or above 1:32 (78.9% vs 45.5%; P<.001) and to have received no prenatal care (58.4% vs 33.1%; P<.001) than people with liveborn neonates with congenital syphilis. The risk of stillbirth was twice as high in persons with secondary syphilis compared with those with primary syphilis (11.5% vs 5.7%, risk ratio 2.00; 95% CI, 1.27-3.13). Across all congenital syphilis cases, 34.2% of people did not have a syphilis test at their first prenatal visit. CONCLUSION: Stillbirths occurred in more than 1 in 20 pregnancies complicated by congenital syphilis. Risk factors for stillbirth included high titers, secondary stage, and lack of prenatal care. If the prevalence of congenital syphilis continues to rise, there will be a corresponding increase in the overall stillbirth rate nationally. |
Pandemic demand for SARS-CoV-2 testing led to critical supply and workforce shortages in U.S. clinical and public health laboratories
Cornish NE , Bachmann LH , Diekema DJ , McDonald LC , McNult P , Stevens-Garcia J , Raphael BH , Miller MB . J Clin Microbiol 2023 61 (7) e0318920 ![]() COVID-19 has brought unprecedented challenges to clinical and public health laboratories. While U.S. laboratories have continued striving to provide quality test results during the pandemic, the uncertainty and lack of supplies became a significant hurdle, hindering day-to-day laboratory operations and the ability to increase testing capacity for both SARS-CoV-2 and non-COVID-19 testing. In addition, long-standing laboratory workforce shortages became apparent, hindering the ability of clinical and public health laboratories to rapidly increase testing. The American Society for Microbiology, the College of American Pathologists, the National Coalition of STD Directors, and the Emerging Infections Network independently conducted surveys in 2020 and early 2021 to assess the capacity of the nation's clinical laboratories to respond to the increase in demand for testing during the COVID-19 pandemic. The results of these surveys highlighted the shortages of crucial supplies for SARS-CoV-2 testing and supplies for other routine laboratory diagnostics, as well as a shortage of trained personnel to perform testing. The conclusions are based on communications, observations, and the survey results of the clinical laboratory, public health, and professional organizations represented here. While the results of each survey considered separately may not be representative of the entire community, when considered together they provide remarkably similar results, further validating the findings and highlighting the importance of laboratory supply chains and the personnel capable of performing these tests for any response to a large-scale public health emergency. |
Geographic variation in access to cardiac rehabilitation
Duncan MS , Robbins NN , Wernke SA , Greevy RA Jr , Jackson SL , Beatty AL , Thomas RJ , Whooley MA , Freiberg MS , Bachmann JM . J Am Coll Cardiol 2023 81 (11) 1049-1060 BACKGROUND: There is marked geographic variation in cardiac rehabilitation (CR) initiation, ranging from 10% to 40% of eligible patients at the state level. The potential causes of this variation, such as patient access to CR centers, are not well studied. OBJECTIVES: The authors sought to determine how access to CR centers affects CR initiation in Medicare beneficiaries. METHODS: The authors used Medicare files to identify CR-eligible Medicare beneficiaries and calculate CR initiation rates at the hospital referral region (HRR) level. We used linear regression to evaluate the percent variation in CR initiation accounted for by CR access across HRRs. We then employed geospatial hotspot analysis to identify CR deserts, or counties in which patient load per CR center is disproportionately high. RESULTS: A total of 1,133,657 Medicare beneficiaries were eligible for CR from 2014 to 2017, of whom 263,310 (23%) initiated CR. The West North Central Census Division had the highest adjusted CR initiation rate (35.4%) and the highest density of CR programs (6.58 per 1,000 CR-eligible Medicare beneficiaries). Density of CR programs accounted for 21.2% of geographic variation in CR initiation at the HRR level. A total of 40 largely urban counties comprising 14% of the United States population age ≥65 years had disproportionately low CR access and were identified as CR deserts. CONCLUSIONS: A substantial proportion of geographic variation in CR initiation was related to access to CR programs, with a significant amount of the U.S. population living in CR deserts. These data invite further study on interventions to increase CR access. |
Congenital syphilis in the Medicaid program: Assessing challenges and opportunities through the experiences of seven southern states
Seiler N , Pearson WS , Bachmann LH , Heyison C , Organick-Lee P , Karacuschansky A , Dwyer G , Osei A , Stoll H , Horton K . Womens Health Issues 2023 33 (4) 349-358 INTRODUCTION: Rates of congenital syphilis cases are increasing, particularly among lower socioeconomic populations within the southern United States. Medicaid covers a significant portion of these births, which provides an opportunity to improve birth outcomes. This project sought to collect information from key stakeholders to assess facilitators of and barriers to Medicaid funding of prenatal syphilis screening and to provide insight into improving screening and lowering incidence through the Medicaid program. METHODS: Seven southern states (Alabama, Georgia, Kentucky, Louisiana, North Carolina, South Carolina, and Tennessee) were identified for this assessment. Researchers conducted a legal and policy analysis for each state to gather information on factors affecting congenital syphilis prevention, identifying knowledge gaps, and inform the development of interview guides. Seventeen structured interviews with 29 participants were conducted to gather information on facilitators and barriers to receiving timely prenatal syphilis screening through the Medicaid program. Interview transcripts were analyzed and compared to identify key themes. RESULTS: Barriers to timely prenatal syphilis screening include varied laws among the states on the timing of screening, Medicaid reimbursement policies that may not adequately incentivize testing, Medicaid enrollment issues that affect both enrollment and continuity of care, and lack of clear understanding among providers on recommended testing. CONCLUSION: This work provides insight into systemic issues that may be affecting rates of prenatal syphilis screening and incidence among Medicaid enrollees and others in the U.S. South. To address rising congenital syphilis cases, policymakers should consider requiring third trimester syphilis screening, adopting policies to enhance access to prenatal care, adapting Medicaid payment and incentive models, and promoting collaboration between Medicaid and public health agencies. |
Mpox virus and transmission through sexual contact: Defining the research agenda

Field services facilitated treatment and prevention: Challenges and opportunities
Bachmann LH , Kerani RP . Sex Transm Dis 2022 50 S48-S52 Assisted partner services (APS) is a longstanding public health strategy to reduce transmission of STI and HIV in the U.S. However, with rapidly increasing rates of STI, innovations to APS are needed to allow health departments to conserve limited public health resources while improving the effectiveness of APS. Disease Intervention Specialists (DIS), public health staff who conduct APS, have a wealth of experience in identifying, locating, and interviewing index patients and their sexual partners, but are currently limited in the services that they are able to provide in the field. While several state and local health departments are working to expand the role of DIS to incorporate less traditional APS activities, such programs are uncommon. We discuss several services that DIS could conceivably provide in the field, such as STI testing, treatment, and vaccination, and identify critical issues to be addressed in order to implement these changes in DIS activities on a larger scale. Broadening the scope of DIS activities may result in multiple benefits to health departments, including more effectively delivering STI testing and treatment to hard to reach populations, imparting more responsibility to DIS, thereby potentially increasing job satisfaction, and building a workforce that is better prepared for public health crises. Effective approaches to address variable state level regulations governing DIS scope of practice are needed. |
HIV and sexually transmitted infections among persons with Monkeypox - eight U.S. Jurisdictions, May 17-July 22, 2022
Curran KG , Eberly K , Russell OO , Snyder RE , Phillips EK , Tang EC , Peters PJ , Sanchez MA , Hsu L , Cohen SE , Sey EK , Yin S , Foo C , Still W , Mangla A , Saafir-Callaway B , Barrineau-Vejjajiva L , Meza C , Burkhardt E , Smith ME , Murphy PA , Kelly NK , Spencer H , Tabidze I , Pacilli M , Swain CA , Bogucki K , DelBarba C , Rajulu DT , Dailey A , Ricaldi J , Mena LA , Daskalakis D , Bachmann LH , Brooks JT , Oster AM . MMWR Morb Mortal Wkly Rep 2022 71 (36) 1141-1147 High prevalences of HIV and other sexually transmitted infections (STIs) have been reported in the current global monkeypox outbreak, which has affected primarily gay, bisexual, and other men who have sex with men (MSM) (1-5). In previous monkeypox outbreaks in Nigeria, concurrent HIV infection was associated with poor monkeypox clinical outcomes (6,7). Monkeypox, HIV, and STI surveillance data from eight U.S. jurisdictions* were matched and analyzed to examine HIV and STI diagnoses among persons with monkeypox and assess differences in monkeypox clinical features according to HIV infection status. Among 1,969 persons with monkeypox during May 17-July 22, 2022, HIV prevalence was 38%, and 41% had received a diagnosis of one or more other reportable STIs in the preceding year. Among persons with monkeypox and diagnosed HIV infection, 94% had received HIV care in the preceding year, and 82% had an HIV viral load of <200 copies/mL, indicating HIV viral suppression. Compared with persons without HIV infection, a higher proportion of persons with HIV infection were hospitalized (8% versus 3%). Persons with HIV infection or STIs are disproportionately represented among persons with monkeypox. It is important that public health officials leverage systems for delivering HIV and STI care and prevention to reduce monkeypox incidence in this population. Consideration should be given to prioritizing persons with HIV infection and STIs for vaccination against monkeypox. HIV and STI screening and other recommended preventive care should be routinely offered to persons evaluated for monkeypox, with linkage to HIV care or HIV preexposure prophylaxis (PrEP) as appropriate. |
Monkeypox outbreak - nine states, May 2022
Minhaj FS , Ogale YP , Whitehill F , Schultz J , Foote M , Davidson W , Hughes CM , Wilkins K , Bachmann L , Chatelain R , Donnelly MAP , Mendoza R , Downes BL , Roskosky M , Barnes M , Gallagher GR , Basgoz N , Ruiz V , Kyaw NTT , Feldpausch A , Valderrama A , Alvarado-Ramy F , Dowell CH , Chow CC , Li Y , Quilter L , Brooks J , Daskalakis DC , McClung RP , Petersen BW , Damon I , Hutson C , McQuiston J , Rao AK , Belay E , McCollum AM . MMWR Morb Mortal Wkly Rep 2022 71 (23) 764-769 On May 17, 2022, the Massachusetts Department of Public Health (MDPH) Laboratory Response Network (LRN) laboratory confirmed the presence of orthopoxvirus DNA via real-time polymerase chain reaction (PCR) from lesion swabs obtained from a Massachusetts resident. Orthopoxviruses include Monkeypox virus, the causative agent of monkeypox. Subsequent real-time PCR testing at CDC on May 18 confirmed that the patient was infected with the West African clade of Monkeypox virus. Since then, confirmed cases* have been reported by nine states. In addition, 28 countries and territories,(†) none of which has endemic monkeypox, have reported laboratory-confirmed cases. On May 17, CDC, in coordination with state and local jurisdictions, initiated an emergency response to identify, monitor, and investigate additional monkeypox cases in the United States. This response has included releasing a Health Alert Network (HAN) Health Advisory, developing interim public health and clinical recommendations, releasing guidance for LRN testing, hosting clinician and public health partner outreach calls, disseminating health communication messages to the public, developing protocols for use and release of medical countermeasures, and facilitating delivery of vaccine postexposure prophylaxis (PEP) and antivirals that have been stockpiled by the U.S. government for preparedness and response purposes. On May 19, a call center was established to provide guidance to states for the evaluation of possible cases of monkeypox, including recommendations for clinical diagnosis and orthopoxvirus testing. The call center also gathers information about possible cases to identify interjurisdictional linkages. As of May 31, this investigation has identified 17(§) cases in the United States; most cases (16) were diagnosed in persons who identify as gay, bisexual, or men who have sex with men (MSM). Ongoing investigation suggests person-to-person community transmission, and CDC urges health departments, clinicians, and the public to remain vigilant, institute appropriate infection prevention and control measures, and notify public health authorities of suspected cases to reduce disease spread. Public health authorities are identifying cases and conducting investigations to determine possible sources and prevent further spread. This activity was reviewed by CDC and conducted consistent with applicable federal law and CDC policy.(¶). |
Centers for Disease Control and Prevention's Sexually Transmitted Diseases Infection Guidelines
Workowski KA , Bachmann LH . Clin Infect Dis 2022 74 S89-s94 Sexually transmitted infections (STIs) constitute an epidemic of tremendous magnitude, with an estimated 27 million persons acquiring a new STI in 2018 at a cost of $16 billion [1, 2]. Reported disease rates underestimate the true burden of infection because the majority of STIs are asymptomatic and underreported [3]. STIs have far-reaching public health consequences on the sexual and reproductive health of individuals, as well as long-term healthcare costs to the community [2]. Due to the dramatic increase in reportable STI rates with resultant reproductive health consequences, an STI National Strategic Plan (https://www.hhs.gov/sites/default/files/STI-National-Strategic-Plan-2021-2025.pdf) was developed with actionable goals, objectives, and strategies for prevention that focus on 4 of the STIs with the highest morbidity rates (chlamydia, gonorrhea, syphilis, and human papillomavirus), though most of the components of the plan are applicable to other STIs (herpes simplex virus, trichomoniasis, Mycoplasma genitalium). |
Congenital syphilis-related stillbirths in the United States from 2015 to 2019
Machefsky Aliza , Miele Kathryn , Kimball Anne , Thorpe Phoebe , Bachmann Laura , Bowen Virginia . Am J Obstet Gynecol 2022 226 (2) 303-304 Objectives | Given recent increases in congenital syphilis (CS) in the United States, we describe national trends in the number of CS-related stillbirths, describe CS-related stillbirths by gestational age, and compare characteristics of women delivering CS-related stillbirths to those delivering full term and preterm liveborn CS infants to provide important clinical insight. | | Methods | CS is nationally notifiable with case reports submitted to Centers for Disease Control and Prevention (CDC). We analyzed reported cases of CS born during 20152019, categorizing birth outcomes as stillbirth, preterm <37 weeks, or full term 37 weeks; cases with unknown vital status or gestational age were excluded. We calculated frequencies of maternal clinical characteristics by birth outcome, including receipt of prenatal care, stage of syphilis, and highest reported titer during pregnancy. | | Results | Of the 5,269 CS cases reported to CDC for 20152019, 5,127 (97.3%) had known vital status and gestational age. Among these, 307 (6.0%) were stillbirths. While the number of CS-related stillbirths increased each year during 20152019 (from 2994), the proportion of CS cases reported as stillbirths did not vary considerably across the period (range: 5.1%7.3%). Median gestational age at delivery for CS-related stillbirths was 30 weeks (interquartile range: 2733 weeks). Most CS cases were born to mothers with early latent (31.4%) or late/unknown duration (59.7%) syphilis, though mothers of stillborn infants were 2.3 times as likely as mothers of full term liveborn infants to have secondary syphilis (10.8% vs. 4.6%). Adverse pregnancy outcomes were more likely to have a high maternal syphilis titer; 80.8% of stillbirth, 58.1% of preterm, and 40.2% of full-term deliveries occurred among women with a titer 1:32 during pregnancy. Among women delivering a CS-related stillbirth, 33 (10.7%) had evidence of syphilis seroconversion during pregnancy. Most mothers delivering a CS-related stillbirth (53.4%) did not receive prenatal care, compared to mothers delivering full term liveborn CS infants (18.4%). | | Conclusions | Increases in CS-related stillbirths in the United States reflect increases in CS cases; without prevention efforts, CS could become a larger contributor to overall U.S. stillbirth levels. Understanding when CS-related stillbirths occur, as well as the differences between women delivering CS-related stillbirths and women delivering liveborn CS infants (higher titer, syphilis stage, and prenatal care) may aid with stillbirth prevention. Overcoming barriers to prenatal care is essential for preventing CS stillbirths. Low rates of prenatal care also highlight the importance of syphilis testing outside traditional settings and at the time of stillbirth delivery. Delivery may provide a rare interaction with the healthcare system enabling syphilis testing and treatment, and prevention of future CS-related adverse outcomes. |
Congenital syphilis diagnosed beyond the neonatal period in the United States: 2014-2018
Kimball A , Bowen VB , Miele K , Weinstock H , Thorpe P , Bachmann L , McDonald R , Machefsky A , Torrone E . Pediatrics 2021 148 (3) BACKGROUND AND OBJECTIVES: During 2014-2018, reported congenital syphilis (CS) cases in the United States increased 183%, from 462 to 1306 cases. We reviewed infants diagnosed with CS beyond the neonatal period (>28 days) during this time. METHODS: We reviewed surveillance case report data for infants with CS delivered during 2014-2018 and identified those diagnosed beyond the neonatal period with reported signs or symptoms. We describe these infants and identify possible missed opportunities for earlier diagnoses. RESULTS: Of the 3834 reported cases of CS delivered during 2014-2018, we identified 67 symptomatic infants diagnosed beyond the neonatal period. Among those with reported findings, 67% had physical examination findings of CS, 69% had abnormal long-bone radiographs consistent with CS, and 36% had reactive syphilis testing in the cerebrospinal fluid. The median serum nontreponemal titer was 1:256 (range: 1:1-1:2048). The median age at diagnosis was 67 days (range: 29-249 days). Among the 66 mothers included, 83% had prenatal care, 26% had a syphilis diagnosis during pregnancy or at delivery, and 42% were not diagnosed with syphilis until after delivery. Additionally, 24% had an initial negative test result and seroconverted during pregnancy. CONCLUSIONS: Infants with CS continue to be undiagnosed at birth and present with symptoms after age 1 month. Pediatric providers can diagnose and treat infants with CS early by following guidelines, reviewing maternal records and confirming maternal syphilis status, advocating for maternal testing at delivery, and considering the diagnosis of CS, regardless of maternal history. |

Workowski KA , Bachmann LH , Chan PA , Johnston CM , Muzny CA , Park I , Reno H , Zenilman JM , Bolan GA . MMWR Recomm Rep 2021 70 (4) 1-187 These guidelines for the treatment of persons who have or are at risk for sexually transmitted infections (STIs) were updated by CDC after consultation with professionals knowledgeable in the field of STIs who met in Atlanta, Georgia, June 11-14, 2019. The information in this report updates the 2015 guidelines. These guidelines discuss 1) updated recommendations for treatment of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis; 2) addition of metronidazole to the recommended treatment regimen for pelvic inflammatory disease; 3) alternative treatment options for bacterial vaginosis; 4) management of Mycoplasma genitalium; 5) human papillomavirus vaccine recommendations and counseling messages; 6) expanded risk factors for syphilis testing among pregnant women; 7) one-time testing for hepatitis C infection; 8) evaluation of men who have sex with men after sexual assault; and 9) two-step testing for serologic diagnosis of genital herpes simplex virus. Physicians and other health care providers can use these guidelines to assist in prevention and treatment of STIs. |
A New Call to Action to Combat an Old Nemesis: Addressing Rising Congenital Syphilis Rates in the United States
Machefsky AM , Loosier PS , Cramer R , Bowen VB , Kersh EN , Tao G , Gift TL , Hogben M , Carry M , Ludovic JA , Thorpe P , Bachmann LH . J Womens Health (Larchmt) 2021 30 (7) 920-926 Congenital syphilis (CS) is on the rise in the United States and is a growing public health concern. CS is an infection with Treponema pallidum in an infant or fetus, acquired via transplacental transmission when a pregnant woman has untreated or inadequately treated syphilis. Pregnant women with untreated syphilis are more likely to experience pregnancies complicated by stillbirth, prematurity, low birth weight, and early infant death, while their children can develop clinical manifestations of CS such as hepatosplenomegaly, bone abnormalities, developmental delays, and hearing loss. One of the ways CS can be prevented is by identifying and treating infected women during pregnancy with a benzathine penicillin G regimen that is both appropriate for the maternal stage of syphilis and initiated at least 30 days prior to delivery. In this article we discuss many of the challenges faced by both public health and healthcare systems with regards to this preventable infection, summarize missed opportunities for CS prevention, and provide practical solutions for future CS prevention strategies. |
Gonococcal vaccines: Public health value and preferred product characteristics; report of a WHO global stakeholder consultation, January 2019
Gottlieb SL , Ndowa F , Hook EW3rd , Deal C , Bachmann L , Abu-Raddad L , Chen XS , Jerse A , Low N , MacLennan CA , Petousis-Harris H , Seib KL , Unemo M , Vincent L , Giersing BK . Vaccine 2020 38 (28) 4362-4373 Renewed interest in developing vaccines against Neisseria gonorrhoeae has been sparked by the increasing threat of gonococcal antimicrobial resistance (AMR) and growing optimism that gonococcal vaccines are biologically feasible. Evidence suggests serogroup B Neisseria meningitidis vaccines might provide some cross-protection against N. gonorrhoeae, and new gonococcal vaccine candidates based on several approaches are currently in preclinical development. To further stimulate investment and accelerate development of gonococcal vaccines, greater understanding is needed regarding the overall value that gonococcal vaccines might have in addressing public health and societal goals in low-, middle-, and high-income country contexts and how future gonococcal vaccines might be accepted and used, if available. In January 2019, the World Health Organization (WHO) convened a multidisciplinary international group of experts to lay the groundwork for understanding the potential health, economic, and societal value of gonococcal vaccines and their likely acceptance and use, and for developing gonococcal vaccine preferred product characteristics (PPCs). WHO PPCs describe preferences for vaccine attributes that would help optimize vaccine value and use in meeting the global public health need. This paper describes the main discussion points and conclusions from the January 2019 meeting of experts. Participants emphasized the need for vaccines to control N. gonorrhoeae infections with the ultimate goals of preventing adverse sexual and reproductive health outcomes (e.g., infertility) and reducing the impact of gonococcal AMR. Meeting participants also discussed important PPC considerations (e.g., vaccine indications, target populations, and potential immunization strategies) and highlighted crucial research and data needs for guiding the value assessment and PPCs for gonococcal vaccines and advancing gonococcal vaccine development. |

Sex Transm Dis 2021 48 (11) e160-e162 During the 2017-2018 National Health and Nutrition Examination Survey, urine samples from participants aged 14-59 years were tested for Mycoplasma genitalium infection. Overall prevalence was 1.7% (95% CI: 1.1%, 2.7%). Prevalence was similar between males (1.8%, 95% CI: 0.9%, 3.1%) and females (1.7%, 95% CI: 0.8%, 3.0%). |
Update to CDC's Treatment Guidelines for Gonococcal Infection, 2020
St Cyr S , Barbee L , Workowski KA , Bachmann LH , Pham C , Schlanger K , Torrone E , Weinstock H , Kersh EN , Thorpe P . MMWR Morb Mortal Wkly Rep 2020 69 (50) 1911-1916 Sexually transmitted infections (STIs) caused by the bacteria Neisseria gonorrhoeae (gonococcal infections) have increased 63% since 2014 and are a cause of sequelae including pelvic inflammatory disease, ectopic pregnancy, and infertility and can facilitate transmission of human immunodeficiency virus (HIV) (1,2). Effective treatment can prevent complications and transmission, but N. gonorrhoeae's ability to acquire antimicrobial resistance influences treatment recommendations and complicates control (3). In 2010, CDC recommended a single 250 mg intramuscular (IM) dose of ceftriaxone and a single 1 g oral dose of azithromycin for treatment of uncomplicated gonococcal infections of the cervix, urethra, and rectum as a strategy for preventing ceftriaxone resistance and treating possible coinfection with Chlamydia trachomatis (4). Increasing concern for antimicrobial stewardship and the potential impact of dual therapy on commensal organisms and concurrent pathogens (3), in conjunction with the continued low incidence of ceftriaxone resistance and the increased incidence of azithromycin resistance, has led to reevaluation of this recommendation. This report, which updates previous guidelines (5), recommends a single 500 mg IM dose of ceftriaxone for treatment of uncomplicated urogenital, anorectal, and pharyngeal gonorrhea. If chlamydial infection has not been excluded, concurrent treatment with doxycycline (100 mg orally twice a day for 7 days) is recommended. Continuing to monitor for emergence of ceftriaxone resistance through surveillance and health care providers' reporting of treatment failures is essential to ensuring continued efficacy of recommended regimens. |
Optimising treatments for sexually transmitted infections: surveillance, pharmacokinetics and pharmacodynamics, therapeutic strategies, and molecular resistance prediction.
Sena AC , Bachmann L , Johnston C , Wi T , Workowski K , Hook EW 3rd , Hocking JS , Drusano G , Unemo M . Lancet Infect Dis 2020 20 (8) e181-e191 ![]() ![]() Progressive antimicrobial resistance in Neisseria gonorrhoeae, Mycoplasma genitalium, and Trichomonas vaginalis has created a pressing need for treatment optimisations for sexually transmitted infections (STIs). In this Review, we aim to highlight urgent needs in global STI management, including: (1) improved surveillance to monitor antimicrobial resistance and clinical outcomes; (2) systematic pharmacokinetic and pharmacodynamic evaluations to ensure resistance suppression and bacterial eradication at all sites of infection; (3) development of novel, affordable antimicrobials; and (4) advancements in new molecular and point-of-care tests to detect antimicrobial resistance determinants. Antimicrobial resistance among STIs is a global public health crisis. Continuous efforts to develop novel antimicrobials will be essential, in addition to other public health interventions to reduce the global STI burden. Apart from prevention through safer sexual practices, the development of STI vaccines to prevent transmission is a crucial research priority. |
Missed opportunities for prevention of congenital syphilis - United States, 2018
Kimball A , Torrone E , Miele K , Bachmann L , Thorpe P , Weinstock H , Bowen V . MMWR Morb Mortal Wkly Rep 2020 69 (22) 661-665 Congenital syphilis is an infection with Treponema pallidum in an infant or fetus, acquired during pregnancy from a mother with untreated or inadequately treated syphilis. Congenital syphilis can cause miscarriage, stillbirth, or early infant death, and infected infants can experience lifelong physical and neurologic problems. Although timely identification and treatment of maternal syphilis during pregnancy can prevent congenital syphilis (1,2), the number of reported congenital syphilis cases in the United States increased 261% during 2013-2018, from 362 to 1,306. Among reported congenital syphilis cases during 2018, a total of 94 resulted in stillbirths or early infant deaths (3). Using 2018 national congenital syphilis surveillance data and a previously developed framework (4), CDC identified missed opportunities for congenital syphilis prevention. Nationally, the most commonly missed prevention opportunities were a lack of adequate maternal treatment despite the timely diagnosis of syphilis (30.7%) and a lack of timely prenatal care (28.2%), with variation by geographic region. Congenital syphilis prevention involves syphilis prevention for women and their partners and timely identification and treatment of pregnant women with syphilis. Preventing continued increases in congenital syphilis requires reducing barriers to family planning and prenatal care, ensuring syphilis screening at the first prenatal visit with rescreening at 28 weeks' gestation and at delivery, as indicated, and adequately treating pregnant women with syphilis (2). Congenital syphilis prevention strategies that implement tailored public health and health care interventions to address missed opportunities can have substantial public health impact. |
Prevalence of Mycoplasma genitalium infection, antimicrobial resistance mutations and symptom resolution following treatment of urethritis
Bachmann LH , Kirkcaldy RD , Geisler WM , Wiesenfeld HC , Manhart LE , Taylor SN , Sena AC , McNeil CJ , Newman L , Myler N , Fuchs R , Bowden KE . Clin Infect Dis 2020 71 (10) e624-e632 BACKGROUND: Antimicrobial resistance in Mycoplasma genitalium (MG), a cause of urethritis, is a growing concern. Yet little is known about the geographic distribution of MG resistance in the U.S. or associated clinical outcomes. We evaluated the frequency of MG among men with urethritis, resistance mutations, and post-treatment symptom persistence. METHODS: We enrolled men presenting with urethritis symptoms to 6 U.S. sexually transmitted disease (STD) clinics during June 2017-July 2018; men with urethritis were eligible for follow-up contact and (if persistent symptoms or MG) chart review. Urethral specimens were tested for MG and other bacterial STDs. Mutations in 23S rRNA loci (macrolide-associated mutations [MRMs]) and parC and gyrA (quinolone-associated mutations [QRMs]) were detected by targeted amplification/Sanger sequencing. RESULTS: Among 914 evaluable participants, 28.7% (95% CI 23.8-33.6) had MG. Men with MG were more often black (79.8% vs 66%), <30 years (72.9% vs 56.1%), and reported only female partners (83.7% vs 74.2%) than men without MG. Among MG-positive participants, 64.4% (95% CI 58.2%-70.3%) had MRM, 11.5% (95% CI 7.9-16.0%) had parC mutations, and 0% had gyrA mutations. Among participants treated with azithromycin-based therapy at enrollment and who completed the follow-up survey, persistent symptoms were reported by 25.8% of MG-positive/MRM-positive men, 13% of MG-positive/MRM-negative men, and 17.2% of MG-negative men. CONCLUSIONS: MG infection was common among men with urethritis; MRM prevalence was high among men with MG. Persistent symptoms following treatment were frequent among men with and without MG. |
Availability of injectable antimicrobial drugs for gonorrhea and syphilis, United States, 2016
Pearson WS , Cherry DK , Leichliter JS , Bachmann LH , Cummings NA , Hogben M . Emerg Infect Dis 2019 25 (11) 2154-2156 We estimated the availability of the injectable antimicrobial drugs recommended for point-of-care treatment of gonorrhea and syphilis among US physicians who evaluated patients with sexually transmitted infections in 2016. Most physicians did not have these drugs available on-site. Further research is needed to determine the reasons for the unavailability of these drugs. |

Crit Rev Microbiol 2019 45 (1) 1-21 Invasive Scedosporium spp. and Lomentospora prolificans infections are an emerging threat in immunocompromised and occasionally in healthy hosts. Scedosporium spp. is intrinsically resistant to most, L. prolificans to all the antifungal drugs currently approved, raising concerns about appropriate treatment decisions. High mortality rates of up to 90% underline the need for comprehensive diagnostic workup and even more for new, effective antifungal drugs to improve patient outcome. For a comprehensive analysis, we identified cases of severe Scedosporium spp. and L. prolificans infections from the literature diagnosed in 2000 or later and the FungiScope((R)) registry. For 208 Scedosporium spp. infections solid organ transplantation (n = 58, 27.9%) and for 56 L. prolificans infection underlying malignancy (n = 28, 50.0%) were the most prevalent risk factors. L. prolificans infections frequently presented as fungemia (n = 26, 46.4% versus n = 12, 5.8% for Scedosporium spp.). Malignancy, fungemia, CNS and lung involvement predicted worse outcome for scedosporiosis and lomentosporiosis. Patients treated with voriconazole had a better overall outcome in both groups compared to treatment with amphotericin B formulations. This review discusses the epidemiology, prognostic factors, pathogen susceptibility to approved and investigational antifungals, and treatment strategies of severe infections caused by Scedosporium spp. and L. prolificans. |
