RESUMEN
BACKGROUND: Differences in opinion concerning the contribution of M. genitalium to pelvic inflammatory disease (PID) has resulted in inconsistencies across global testing and treatment guidelines. We conducted a systematic review and meta-analysis to determine the association between M. genitalium and PID and M. genitalium positivity within PID cases to provide a contemporary evidence base to inform clinical practice (PROSPERO registration: CRD42022382156). METHODS: PubMed, Embase, Medline and Web of Science were searched to Dec 1, 2023 for studies that assessed women for PID using established clinical criteria and used nucleic acid amplification tests to detect M. genitalium. We calculated summary estimates of the 1) association of M. genitalium with PID (pooled odds ratio [OR]) and 2) proportion of PID cases with M. genitalium detected (pooled M. genitalium positivity in PID), using random-effects meta-analyses, with 95% confidence intervals (CI). RESULTS: Nineteen studies were included: 10 estimated M. genitalium association with PID, and 19 estimated M. genitalium positivity in PID. M. genitalium infection was significantly associated with PID (pooled OR=1.67 [95%CI: 1.24-2.24]). The pooled positivity of M. genitalium in PID was 10.3% [95%CI: 5.63-15.99]. Subgroup and meta-regression analyses showed that M. genitalium positivity in PID was highest in the Americas, in studies conducted in both inpatient and outpatient clinic settings, and in populations at high risk of sexually transmitted infections. CONCLUSIONS: M. genitalium was associated with a 67% increase in odds of PID and was detected in about one in ten clinical diagnoses of PID. These data support testing women for M. genitalium at initial PID diagnosis.
RESUMEN
BACKGROUND: There are limited data on the extent of use of online services that support partner notification for sexually transmitted infections. The online partner notification service Let Them Know was implemented in 2008 to support partner messaging for chlamydia in Australia. In 2010, the service was expanded to include gonorrhea, syphilis, Mycoplasma genitalium, and Trichomonas vaginalis. We aimed to determine usage of Let Them Know between 2011 and 2019. METHODS: The number of text messages sent via Let Them Know for each infection between 2011 and 2019 was extracted by using Microsoft SQL Server Management Studio. Users who sent a text message were asked "Were you more likely to let a partner know because of this website?" RESULTS: The number of text messages sent for each infection increased over the evaluation period with a total of 148,256 text messages sent from the service. Sixty-nine percent (103,026) of users indicated that they were more likely to let a partner know because of the website. The number of text messages increased between 2011 and 2019 from 4,666 to 17,889 (283%) for chlamydia, from 2101 to 6328 (201%) for gonorrhea, from 1895 to 4908 (159%) for syphilis, from 703 to 1953 (178%) for M. genitalium, and from 173 to 629 (264%) for trichomonas. CONCLUSIONS: This fully automated partner messaging service showed high and increasing use with data suggesting it helped most users contact partners.

BACKGROUND: Current clinical care for common bacterial STIs (Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Mycoplasma genitalium (MG)) involves empiric antimicrobial therapy when clients are symptomatic, or if asymptomatic, waiting for laboratory testing and recall if indicated. Near-to-patient testing (NPT) can improve pathogen-specific prescribing and reduce unnecessary or inappropriate antibiotic use in treating sexually transmitted infections (STI) by providing same-day delivery of results and treatment. METHODS: We compared the economic cost of NPT to current clinic practice for managing clients with suspected proctitis, non-gonococcal urethritis (NGU), or as an STI contact, from a health provider's perspective. With a microsimulation of 1000 clients, we calculated the cost per client tested and per STI- and pathogen- detected for each testing strategy. Sensitivity analyses were conducted to assess the robustness of the main outcomes. Costs are reported as Australian dollars (2023). RESULTS: In the standard care arm, cost per client tested for proctitis, NGU in men who have sex with men (MSM) and heterosexual men were the highest at $247.96 (95% Prediction Interval (PI): 246.77-249.15), $204.23 (95% PI: 202.70-205.75) and $195.01 (95% PI: 193.81-196.21) respectively. Comparatively, in the NPT arm, it costs $162.36 (95% PI: 161.43-163.28), $158.39 (95% PI: 157.62-159.15) and $149.17 (95% PI: 148.62-149.73), respectively. Using NPT resulted in cost savings of 34.52%, 22.45% and 23.51%, respectively. Among all the testing strategies, substantial difference in cost per client tested between the standard care arm and the NPT arm was observed for contacts of CT or NG, varying from 27.37% to 35.28%. CONCLUSION: We found that NPT is cost-saving compared with standard clinical care for individuals with STI symptoms and sexual contacts of CT, NG, and MG.

Background: Empiric treatment of sexually transmitted infections can cause unnecessary antibiotic use. We determined if near-to-patient-testing (NPT) for Neisseria gonorrhoeae, Chlamydia trachomatis and Mycoplasma genitalium (MG) improved antibiotic-use for a range of clinical presentations. Methods: Clients attending with non-gonococcal urethritis (NGU), proctitis, as STI-contacts, or for an MG-test-of-cure (MG-TOC) between March and December 2021 were recruited. Participants received near-to-patient-testing (NPT-group) for the three STIs using the GeneXpert® System (Cepheid), and concurrent routine-testing by transcription-mediated-amplification (TMA; Aptima, Hologic). Antibiotic-use among NGU or proctitis cases in the NPT-group was compared to clinic-controls undergoing routine-testing only. The proportion in the NPT-group who notified partners <24 hrs of their STI-specific result was calculated. Findings: Among 904 consults by 808 NPT-participants, ≥1 STI was detected in 63/252 (25.0%) with NGU, 22/51 (43.1%) with proctitis, and 167/527 (31.7%) STI-contacts. MG was detected among 35/157 (22.3%) MG-TOC consults. Among NGU and proctitis cases, fewer in the NPT-group received empiric treatment compared to clinic-controls (29.4% [95% CI: 24.3-34.9%] vs 83.8% [95% CI: 79.2-87.8%], p < 0.001), resulting in more NPT-group cases appropriately treated (STI-specific drug/no drug appropriately; 80.9% [95% CI: 76.0-85.1%] vs 33.0% [95% CI: 27.7-38.6%], p < 0.001) and fewer mistreated (incorrect drug/treated but pathogen-negative; 17.8% [13.7-22.6%] vs 61.4% [55.6-66.9%], p < 0.001). Of 167/264 in the NPT-group with an STI who responded regarding partner-notification, 95.2% notified all/some partners; 85.9% notified them <24 hrs of the STI-specific result. Interpretation: Near-to-patient-testing significantly improved antibiotic use and a high proportion of individuals rapidly notified partners of STI-specific results, highlighting the broad benefits of timely diagnostic strategies for STIs in clinical decision making and partner notification.

RESUMEN
Background: To examine completion of the human papillomavirus (HPV) vaccination 3-dose regimen and factors associated with completion among men who have sex with men (MSM) aged ≤ 26 years participating in a time-limited HPV catch-up vaccination program in Victoria, Australia. Methods: MSM who received their first dose of HPV vaccine at Melbourne Sexual Health Centre in 2017 were followed until October 2019. Vaccination completion was defined as those who received three doses. Multivariable logistic regression was performed to examine factors associated with vaccine completion. Results: 931 of 1,947 (47.8%) eligible men received at least one dose of HPV vaccine, 750 (38.5%) received two and 590 (30.3%) received three doses. The median time to receiving the second and third dose was 2.8 (IQR = 2.1-4.8) and 7.2 (IQR = 6.3-10.7) months, respectively. Gay men had higher odds of receiving three doses compared to bisexual men (aOR = 2.17; 95%CI: 1.16-4.04). Compared with HIV-negative MSM not taking PrEP, HIV-positive MSM were more like to complete vaccination (aOR = 3.92, 95%CI: 1.62-9.47) but no difference was found compared to HIV-negative men taking PrEP (aOR = 1.55; 95%CI: 0.95-2.53). Conclusion: Less than one-third of men aged ≤ 26 years completed the three doses of HPV vaccine. Further studies are needed to understand the barriers of men not completing the vaccine.
