Background: Genital herpes etiology has been shifting to include a greater proportion of herpes simplex virus type 1 (HSV-1) infection in the last few decades. A prior study published in 2003 found that 48.9% of infections in a college health population were HSV-1.

Methods: We evaluated the number of positive HSV polymerase chain reaction test results obtained from anogenital sites from undergraduate and graduate students from 2013 to 2022 in a college health clinic setting and analyzed the number caused by HSV-1 and HSV type 2 and compared by sex. This was then compared with the prior study from 1993 to 2001.

Results: We received 691 (of 2685 samples) positive polymerase chain reaction results for HSV of both types in the period analyzed. Overall, 600 (86.8%) of these were HSV-1, and 520 (75.2%) were in female patients. The prior study in 1993 to 2001 found that 48.9% (244 of 675) of all positive test results were HSV-1; we observed an increase in the percentage of positive HSV-1 over all positive test results of 1.8 ( χ2 = 16.548; P < 0.001).

Conclusions: Our study shows that 86.8% of the positive genital HSV test results from 2013 to 2022 were HSV-1. This shows that most positive HSV test results in this setting are now HSV-1, a substantial increase from the previous study in our clinic.

Background: National case rates of chlamydia and gonorrhea (CT/GC) among American Indian and Alaska Native (AI/AN) persons are disproportionately high. The Indian Health Service (IHS), which provides health care to members of federally recognized tribes, does not currently have a dedicated CT/GC surveillance system. The purpose of this study was to validate the use of CT/GC diagnostic codes for estimating diagnosed CT/GC infections among AI/AN persons who use IHS services.

Methods: We conducted a retrospective study using IHS medical records from all persons 15 years and older from 2016 to 2021. We linked records with CT (A56, A74) and GC (A54, O98.2) International Classification of Diseases, 10th Revision, Clinical Modification diagnostic codes to laboratory results within 30 days for each person. We calculated the sensitivity, specificity, and positive and negative predictive values of CT/GC diagnostic codes using laboratory test results as the reference standard.

Results: We identified more than 1.6 million CT/GC laboratory tests, and 52,815 CT and 19,971 GC diagnostic codes. Diagnostic code sensitivity was slightly higher for CT (54%) than GC (50%). Specificity, positive predictive value, and negative predictive value were high for CT and GC (range, 83.3%-99.8%). About one-third of CT/GC diagnostic codes could not be linked to a test result.

Conclusions: The validation indicates that diagnostic codes align well with linked laboratory test results. However, because of the relatively large number of diagnostic codes and positive test results that could not be linked, combining the 2 would inform more reliable estimates of diagnosed CT/GC infections among AI/AN persons who use IHS for health care.

Abstract: Congenital syphilis rates increased 10-fold from 2012 to 2022 in the United States. Currently, the therapeutic standard of care is 10 days of intravenous aqueous crystalline penicillin G, with very limited evidence for alternatives. A long course of intravenous antibiotic requires hospitalization that is both costly and burdensome for the child and the family. Fortunately, Treponema pallidum retains susceptibility to other antibiotics based on minimum inhibitory concentrations. Based on the evidence of safety and efficacy of different antibiotics for use in neonates, ceftriaxone emerges as a potential parenteral candidate, and amoxicillin emerges as a potential oral candidate for the treatment of congenital syphilis. Other therapeutic alternatives include cefotaxime (where available), ampicillin, doxycycline, cefixime, and linezolid.

Abstract: This retrospective cohort study drawing data from 48 major tertiary children's hospitals found heterogeneity in the diagnosis and management of congenital syphilis despite Centers for Disease Control and Prevention guideline recommendations. The noted overall rise in the number of congenital syphilis cases mirrors the nationwide increase.

Abstract: The dramatic increase in syphilis cases in the United States in recent years is a serious public health concern. Periodic shortages of benzathine penicillin (BPG), the mainstay of syphilis treatment, create challenges for management of syphilis in the U.S. and worldwide. The National Institute of Allergy and Infectious Diseases (NIAID) convened working groups of experts to assess the landscape of syphilis treatments for uncomplicated adult syphilis, syphilis in pregnant persons, congenital syphilis, and neurosyphilis. The working groups came together at a workshop entitled "Alternative Therapies to Penicillin for the Treatment of Syphilis" on February 13-14, 2024, to share their findings regarding promising alternative treatments, research gaps, and challenges. Discussions focused on utilizing existing antibiotics, with a preference for those with favorable safety profiles and demonstrated success against syphilis or other infectious diseases. Clinical research on alternative treatments is complicated by the high effectiveness of penicillin and by differences in clinical, physiological, cultural, and socioeconomic considerations across different patient populations and geographic settings. In addition, current diagnostic tests and tests-of-cure create challenges for clinical trial design. Various potential trial designs were discussed, focusing on subjects with different types and stages of disease. This summary of the workshop is presented to inform plans for future research, including clinical trials on alternatives to penicillin for the treatment of syphilis.

Abstract: Background: The incidence of syphilis among cisgender women and heterosexual men in the U.S. has risen sharply. Public Health - Seattle & King County (PHSKC) implemented a voluntary, opt-in syphilis screening program in a jail to reach disproportionately affected populations outside the healthcare system.Methods: PHSKC Disease Intervention Specialists (DIS) conducted syphilis screening four days per week in a regional jail. All persons screened January 2022 - March 2023 were included in the analysis. DIS performed point-of-care treponemal-specific tests, collected demographic and risk factor data, worked with jail medical providers to coordinate empiric treatment and confirmatory testing, and determined syphilis history and stage. We categorized persons with reactive rapid tests as "confirmed", "presumed", "possible", or "not new" cases based on confirmatory testing and syphilis history. We compared the characteristics of confirmed cases to overall King County syphilis cases using chi-square tests and examined treatment completion by diagnosis category.Results: 1,371 persons completed screening; 69 (5.0%) had positive results, of whom 51 (73.9%) had confirmatory testing, and 33 had confirmed infections (2.4% of screened persons). Compared to all King County syphilis cases, confirmed cases were more likely to be cisgender women (30.3% vs. 21.9%) or cisgender heterosexual men (66.7% vs. 20.6%), people living homeless (66.7% vs. 24.3%), or people who use methamphetamine (90.9% vs 20.3%) (p < 0.001 for all comparisons). Among 33 persons with confirmed syphilis, 29 (87.8%) started and 18 (54.5%) completed treatment.Conclusions: Jail screening reached persons at disproportionate risk for syphilis, but treatment was often incomplete.

Background: Female sex workers (FSW) have a higher burden of sexually transmitted infections (STI), including Neisseria gonorrhoeae (NG), than the non-sex worker population, mainly due to social vulnerability and work-related factors. This large study evaluated the anatomical site distribution of NG, and specifically the occurrence of single-site pharyngeal NG, among FSW visiting Dutch STI clinics in the Netherlands.

Methods: Coded STI clinic consultations from FSW attending any Dutch STI clinic between 2016 and 2021, in which tests were performed on all three anatomical sites, according to the Dutch testing policy for FSW, were included in analyses (n = 22,304). To compare the anatomical site distribution of NG among FSW with women in general, 15,494 consultations from women who were tested on three anatomical sites in clinics that performed standard testing at three anatomical sites were used. Descriptive statistics were used to compare the anatomical site distribution of NG and occurrence of single-site pharyngeal NG among FSW and universally tested women.

Results: NG was diagnosed among 3.5% (782/22,034) among FSW and 1.7% (271/15,494) among universally tested women (p < 0.001). Pharyngeal NG was diagnosed among 2.3% among FSW, versus 0.8% among universally tested women (p < 0.001). Single-site pharyngeal NG was diagnosed in 19.9% (156/782) of all NG infections, compared to 14.8% (40/271) of NG infections among universally tested women.

Conclusion: The substantial proportion pharyngeal NG and single-site pharyngeal NG among FSW, confirms the relevance of pharyngeal testing among this key population for optimal patient management, also in the context of the potential role of pharyngeal NG in antimicrobial resistance.
