Phylogenomic analysis reveals persistence of gonococcal strains with reduced-susceptibility to extended-spectrum cephalosporins and mosaic penA-34.

Nat Commun 2021 06 21;12(1):3801. Epub 2021 Jun 21.

Division of STD Prevention, Centers for Disease Control and Prevention, Atlanta, GA, USA.

The recent emergence of strains of Neisseria gonorrhoeae associated with treatment failures to ceftriaxone, the foundation of current treatment options, has raised concerns over a future of untreatable gonorrhea. Current global data on gonococcal strains suggest that several lineages, predominately characterized by mosaic penA alleles, are associated with elevated minimum inhibitory concentrations (MICs) to extended spectrum cephalosporins (ESCs). Here we report on whole genome sequences of 813 N. Read More

Social and Behavioral Correlates of Sexually Transmitted Infections among Men who Have Sex with Men who Use Alcohol in the San Francisco Bay Area.

Am J Mens Health 2021 May-Jun;15(3):15579883211026830

Department of Community Health Systems, School of Nursing, University of California, San Francisco, CA, USA.

The risk of acquiring sexually transmitted infections (STIs) among men who have sex with men (MSM) is driven by various socio-behavioral factors. From 2015-2017, 247 MSM ≥ 18 years-old who reported alcohol use in the past year, were recruited into a cross-sectional study in San Francisco. Participants completed a survey assessing socio-demographics, substance use and treatment, sexual behaviors, HIV status and self-reported STI diagnosis in the past 6 months. Read More

J Infect Dis 2021 Jun 16. Epub 2021 Jun 16.

Bureau of Sexually Transmitted Infections, New York City Department of Health and Mental Hygiene, New York, NY, USA.

Early in the COVID-19 crisis, a statewide executive order ("PAUSE") severely restricted the movement of New Yorkers from March 23-June 7, 2020. We used NYC surveillance data for HIV, chlamydia, gonorrhea, and syphilis to describe trends in diagnosis and reporting surrounding PAUSE. During PAUSE, the volume of positive HIV/STI tests, and diagnoses of HIV, chlamydia, gonorrhea, and syphilis declined substantially, reaching a nadir in April before rebounding. Read More

Society for Maternal-Fetal Medicine (SMFM) Consult Series #56: Hepatitis C in Pregnancy: Updated Guidelines.

Am J Obstet Gynecol 2021 Jun 8. Epub 2021 Jun 8.

In the United States, it is estimated that 1% to 4% of pregnant women are infected with hepatitis C virus, which carries approximately a 5% risk of transmission from mother to infant. Hepatitis C virus can be transmitted to the infant in utero or during the peripartum period, and infection during pregnancy is associated with an increased risk of adverse fetal outcomes, including fetal growth restriction and low birthweight. The purpose of this document is to discuss the current evidence, provide updated recommendations regarding screening, review treatment, and address management of hepatitis C virus during pregnancy.

Prevalence of Chlamydia trachomatis Infection in Young Women and Associated Predictors.

Sex Transm Dis 2021 Jan 12. Epub 2021 Jan 12.

*School of Medicine, University of Alabama at Birmingham, Birmingham, AL, USA †Departments of Medicine, University of Alabama at Birmingham, Birmingham, AL, USA ‡Departments of Pediatrics, University of Alabama at Birmingham, Birmingham, AL, USA §Emergency Medicine; University of Alabama at Birmingham, Birmingham, AL, USA ¶Department of Microbiology and Immunology, University of Arkansas for Medical Sciences, Little Rock, AR, USA.

Background: Chlamydia trachomatis (CT) infection remains highly prevalent and young women are disproportionately affected. Most CT-infected women are asymptomatic and their infection often goes unrecognized and untreated. We hypothesized that testing for active CT infection with molecular diagnostics and obtaining a reported history of CT infection underestimates the prevalence of current and past CT infection, and incorporating serum CT antibody testing in addition to these other prevalence measures would generate more accurate estimates of the prevalence of CT infection in asymptomatic young women.

The estimated impact of implementing a funding allocation formula on the number of gonorrhea cases in the United States, 2014-2018.

Sex Transm Dis 2021 Feb 11. Epub 2021 Feb 11.

National Center for HIV, Viral Hepatitis, STD, and TB Prevention, Centers for Disease Control and Prevention, Atlanta, GA.

Background: The Centers for Disease Control and Prevention (CDC) allocates funds annually to state and local programs in the United States to monitor and prevent sexually transmitted diseases (STDs). In 2014 a funding formula was implemented to allocate prevention funds to jurisdictions according to their STD burden and population size. We estimated the effect of implementing the funding formula in terms of gonorrhea cases averted from 2014-2018, a period during which inflation-adjusted CDC STD prevention funding declined.

A Narrative Review of Where We Are With Point-Of-Care STI Testing in the United States.

Sex Transm Dis 2021 May 14. Epub 2021 May 14.

1Division of Infectious Diseases, Department of Medicine, Johns Hopkins University School of Medicine, Baltimore, Maryland.

Introduction: Point-of-care (POC) tests enable immediate diagnosis and targeted treatment for sexually transmitted infections (STIs), which could accelerate control of ongoing epidemics. Although older nucleic acid amplification tests (NAATs) have improved the accuracy of lab-based tests for STIs, newer POC tests can facilitate control efforts. We sought to review the performance and time-to-result of POC assays for STIs in the last ten years. Read More
