RESUMEN
BACKGROUND: The incidence of sexually transmitted infections (STI) continues to increase worldwide. Patient incentives are one proposed intervention to increase STI testing and treatment. METHODS: We conducted a retrospective cohort study comparing incentivized versus routine care for STI outreach test and treat services between October 2018-June 2019. Incentivized care included a $10 gift card for testing visits and an additional $10 gift card for results and/or treatment visits. Incentivized visits were offered to clients with a lack of housing, who were difficult to locate, or had a history of being lost to follow-up. All test and treatment visits included chlamydia, gonorrhea, syphilis, and HIV testing and/or treatment by Registered Nurses and outreach workers from an STI Clinic. Outreach visits were offered at subsidized housing locations, community-based organizations, and street outreach. RESULTS: From October 2018 to June 2019, 2384 outreach clients were reached: 453 (19.0%) receivedincentives and 1931 (81.0%) received routine care. There were no significant differences in case-finding rates for chlamydia (4.8%), gonorrhea (2.9%), and HIV (0.1%); however, there was for syphilis (3.8% for incentivized vs. 1.9% for routine visits; p = 0.02). All newly diagnosed infections identified in the incentivized group received treatment compared with routine visits (chlamydia 100% vs. 79.1%, p = 0.008, gonorrhea 100% vs. 59.7%, p = 0.002, and syphilis 100% vs. 86.7%, p = 0.08). CONCLUSIONS: Incentives were associated with increased case-finding rates of syphilis and were associated with 100% treatment rates. Incentives are a promising approach to decreasing the burden of STI among outreach populations.
RESUMEN
The increased procurement of organs from donors with risk factors for blood-borne diseases and the expanding syphilis epidemic have resulted in a growing number of organs transplanted from donors with reactive syphilis serology in our center. Based on guidelines, recipients typically receive therapy shortly after the transplant, but data on outcomes are limited. The primary objective of this study was to determine syphilis seroconversion rates at three months post-transplant in recipients of solid organs procured from donors with reactive syphilis serology. Organ donors and recipients were tested for syphilis antibody; positive results were confirmed with Treponema pallidum Particle Agglutination (TPPA). Eleven donors with reactive syphilis antibody donated organs to 25 syphilis negative recipients. Three recipients seroconverted at post-transplant month 3. All of them had received therapy shortly after transplant. TPPA was negative in all 3. Despite post-transplant treatment, 3 of 25 (12%) syphilis negative recipients of organs from syphilis positive donors seroconverted at 3 months. All remained TPPA negative possibly reflecting passive antibody transfer or differing test sensitivity to low level treponemal antibodies. Further studies are needed to assess optimal syphilis transmission prevention strategies and follow up recipient testing in organ transplantation.

BACKGROUND: The majority of new human immunodeficiency virus (HIV) infections that occur worldwide are in sub-Saharan Africa. While recent gains have been made in many low- and middle-income countries (LMICs), substantial disparities in sexually transmitted and blood-borne infections (STBBI) screening and treatment still exist between LMIC and high-income countries. In addition to increasing STBBI screening uptake, providing incentives for STBBI screening may decrease perceived stigma associated with STBBI screening. METHODS: Our review was conducted as part of a larger systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and guidance from the Cochrane Handbook for Systematic Reviews of Interventions. This review focuses on incentivized STBBI screening in LMIC; high-income countries were excluded. Articles were excluded if their primary focus was on children and youth (younger than 16 years), results retrieval, treatment, behavioral change only, behavior intention, treatment adherence, or provider incentive. RESULTS: The search yielded 6219 abstracts. The search and selection criteria included all STBBI; however, only articles examining incentivized HIV screening met our inclusion criteria. Five articles representing 4 distinct studies from South Africa, Uganda, and Zimbabwe were included, all of which focused on incentivized HIV screening. Populations screened included the following: men, first-time testers, population-based surveillance program families, and insurance health plan members. Incentive structures varied widely and incentives were mainly food vouchers, lottery prizes, or household items. CONCLUSIONS: Our review was conducted to determine if patient incentives increase STBBI test uptake in LMIC. Overall, incentives were associated with an increase in HIV screening uptake. Most studies included focused solely on men. There is a significant void in understanding STBBI incentive-based screening outside of this context and in complex populations who should be targeted in incentivized HIV screening. Incentives appear most effective when developed specific to context and target population. Further research is needed to analyze incentivized screening across similar study designs, to evaluate long-term effectiveness, and to explore the ethical implications of incentivized care.

BACKGROUND: We sought to examine the correlates for stimulant use in persons diagnosed with infectious syphilis during an outbreak in Alberta to help guide public health interventions. METHODS: Infectious syphilis data were extracted from the Communicable Disease and Outbreak Management database from January 1, 2018, to December 31, 2019. Behavioral, demographic, and lifetime reported stimulant use data were obtained. Descriptive analyses and logistic regression were performed for 3 subpopulations (gay, bisexual, and other men who have sex with men; men who have sex with women; and women). RESULTS: Of 3627 individuals diagnosed with infectious syphilis, 23.9% (n = 867) cases were not interviewed for substance use and were removed from further analysis. Of the remaining 2759 people, 41.8% (n = 1153) self-reported lifetime stimulant use. Gay, bisexual, and other men who have sex with men reported stimulant use less often than women (24.6% vs. 44.1%; P < 0.0001) and men who have sex with women (24.6% vs. 46.2%; P < 0.0001). Multivariable analyses demonstrated that stimulant use was associated with persons who injected drugs, had correctional involvement, or reported multiple sex partners. Men who have sex with women were more likely to self-report First Nations ethnicity (adjusted odds ratio, 1.76 [95% confidence interval, 1.25-2.49]), and women were more likely to have a concurrent gonorrhea infection (adjusted odds ratio, 1.62 [95% confidence interval, 1.15-2.28]). CONCLUSIONS: Nearly half of infectious syphilis cases in Alberta reported lifetime nonprescription stimulant use. Infectious syphilis cases with stimulant use were associated with injection drug use, multiple sex partners, and correctional involvement. Our observations highlight the need for integration of sexual health services into programs for people who use substances and those in corrections custody.

BACKGROUND: Despite increasing access to treatment and screening, rates of sexually transmitted and blood-borne infections (STBBI) continue to rise in high-income countries. The high cost of undiagnosed and untreated STBBI negatively affects individuals, health care systems, and societies. The use of monetary and nonmonetary incentives may increase STBBI screening uptake in high-income countries. Incentivized screening programs are most effective when developed specific to context and target population. METHODS: Our review was performed according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and the Cochrane Handbook for Systematic Reviews of Interventions. Inclusion criteria were as follows: English language, high-income countries, primary research studies, and older than 16 years. Study quality was assessed using Joanna Briggs Institute quality assessment tools. RESULTS: The search yielded 6219 abstracts. Thirteen articles met the inclusion criteria. Studies took place in the United States, the United Kingdom, and Australia. Populations screened included: postsecondary and tertiary students, parolees or probationers, youth, and inner-city emergency department patients. Incentivized STBBI screened were human immunodeficiency virus (n = 5), chlamydia (n = 7), and multiple infections (n = 1). Incentives offered were monetary (cash/gift cards/not specified) (n = 10), nonmonetary (n = 1), and mixed (n = 2). Both monetary and nonmonetary incentives enhance STBBI screening in high-income countries. CONCLUSION: Incentivized screening programs are most effective when developed specific to context and target population. Further research is needed to analyze incentivized screening across similar study designs and to evaluate long-term effectiveness.

BACKGROUND: The aims of this study was to describe molecular surveillance of Neisseria gonorrhoeae in the North Zone of Alberta (NZ) and to determine its value in predicting antimicrobial resistance. METHODS: Sequence types (STs) and single-nucleotide polymorphism (SNP) assays were performed on nucleic acid amplification testing (NAAT) samples. Sequence types of NAATs were matched to ST of cultures from across Alberta. Antimicrobial resistance prediction of NAATs for cephalosporins, azithromycin, and ciprofloxacin using SNP was compared with matching ST culture results using agar dilution and whole-genome sequencing. RESULTS: Of 2755 eligible specimens (2492 cases), 61.9% (1646 specimens) were sent for sequence typing, identifying 196 unique ST. Antimicrobial resistance data for 1307 additional cases were available using matching cultures. Decreased susceptibility (DS) to antimicrobials used for gonorrhea treatment was rare in the NZ; according to the SNP assay, none of the specimens had predicted DS to cephalosporins or azithromycin resistance. However, of the NZ NAAT samples tested in this study, 10.7% (131 of 1220) were predicted to have intermediate cephalosporin minimum inhibitory concentrations and 9.6% (115 of 1204) were resistant to ciprofloxacin. Based on cultures, the proportions of resistance in all of Alberta were as follows: DS to cephalosporins, 0.6% (20 of 3373); DS to intermediate cephalosporin, 16.9% (570 of 3373); azithromycin resistance, 1.2% (41 of 3373); and ciprofloxacin resistance, 32.2% (1087 of 3373). CONCLUSIONS: Our results highlight our ability to use culture-independent methods to predict antimicrobial resistance in N. gonorrhoeae.

PURPOSE OF REVIEW: Neurosyphilis (NS) and Lyme neuroborreliosis (LNB) are spirochetal diseases with distinct clinical manifestations. The diagnosis of NS remains challenging due to imperfect diagnostic criteria and testing modalities. With LNB, misconceptions about diagnosis and treatment lead to considerable morbidity and drug related adverse effects. RECENT FINDINGS: Although studies continue investigating alternate approaches and new diagnostic tests for NS, few data exist to change current approaches to diagnosis, management or follow up. In the diagnosis of LNB, the chemokine CXCL13 shows promising diagnostic accuracy. A systematic review discourages the use of cell-based assays when investigating Lyme disease. Clinical studies show no benefit from extended antibiotic treatment for patients with unspecific symptoms labelled as having Lyme disease. SUMMARY: The diagnosis of NS may be delayed due to a lack of specificity of findings, low suspicion for syphilis, and/or similarities in presentation to other diseases. A high index of suspicion for syphilis is required provide timely diagnosis and management of NS. Fortunately, penicillin remains the treatment of choice. Overdiagnosis and overtreatment in patients labelled as having Lyme disease can be avoided by an evidence-based approach towards diagnosis and treatment.

The focus on urogenital mycoplasmas as the possible etiologic agents of urogenital infections and syndromes, has increased in the last decade. Of these, Mycoplasma genitalium is proven to be pathogenic and sexually transmitted. We compared five commercially available assays for the detection of these organisms in urogenital mycoplasma culture specimen remnants. Stored specimen remnants were tested on Aptima Mycoplasma genitalium, Allplex™ STI Essential and CGMT, ResitancePlus®MG and Allplex™ MG & AziR Assays. All positive M. genitalium specimens and culture negative, nucleic acid positive Ureaplasmas were sent to the National Microbiology Laboratory for confirmation. The Aptima Mycoplasma genitalium assay detected 7 M. genitalium infections, the Allplex™ STI-EA and the Allplex™ CGMT detected 6 M. genitalium positives, and the Allplex™MG and AziR and SpeeDx ResistancePlus® MG detected 5 M. genitalium positives, four with macrolide resistant genes. The Allplex™ STI Essential assay was 100% sensitive and specific for Mycoplasma hominis and Ureaplasma targets. As seen in other studies, the Aptima Mycoplasma genitalium assay was 100% sensitive and specific for the detection of M. genitalium. The multiplex assays had lower sensitivities for M. genitalium detection (Allplex™ STI Essential and CGMT sensitivity of 85.71%; Allplex™ MG & AziR and SpeeDx ResistancePlus® MG sensitivity of 71.43%) with high specificities of 100%. Assays tested have high sensitivities and specificities for the detection of urogenital mycoplasmas especially M. genitalium macrolide resistance markers. All labs wanting to perform onsite detection of these organisms will find an assay to easily fit into their workflow.

PURPOSE OF REVIEW: In the context of a resurgence of syphilis worldwide, it can be anticipated that a rise in cases of ocular, otic, and neurosyphilis will also be seen. This article reviews the current epidemiology, manifestations, and approach to management and treatment. RECENT FINDINGS: Although studies continue investigating alternate approaches and new diagnostic tests for ocular and neurosyphilis, few data exist to change current diagnostic algorithms and approaches to diagnosis, management, or follow up. SUMMARY: The diagnosis of neurologic and eye/ear involvement with syphilis may be delayed because of a lack of specificity of findings, low suspicion for syphilis, fluctuation in symptoms, and/or similarities in presentation to other diseases. A high index of suspicion for syphilis and re-education about the protean manifestations of syphilis by all clinicians is required provide timely diagnosis and management of ocular, otic, and neurosyphilis.

BACKGROUND: A case of gonococcal conjunctivitis (GC) prompted us to review the reported cases and treatment regimens of GC in Alberta, Canada. METHODS: Gonococcal cases reported from 2000 to 2016 were extracted from the provincial sexually transmitted infection reporting database. The diagnosis of GC was based on a positive culture and/or nucleic acid amplification test from the eye. RESULTS: A total of 45 cases of GC were reported in adults. Three quarters (75.6%; n = 34) of the cases were diagnosed using culture, 57.8% (n = 26) of cases were among men, and 55.5% (n = 25) were diagnosed since 2014. Very few (13.3%; n = 6) of the cases were treated according to current Canadian Guidelines on Sexually Transmitted Infections, using 2 g of ceftriaxone in combination with azithromycin or doxycycline. Results of test of cures were available for 15.6% (n = 7) of the cases and occurred within 10 to 79 days (median = 26 days) after treatment; all were negative. CONCLUSIONS: Gonococcal conjunctivitis was relatively uncommon in our region, but given its potential for severe manifestations and sequelae coupled with the rising rates of gonorrhea; it remains important to consider this diagnosis in sexually active individuals presenting with purulent conjunctivitis. Additional studies are needed to inform treatment recommendations and to evaluate outcomes of infection.

BACKGROUND: Erysipelothrix rhusiopathiae is a zoonotic pathogen that causes erysipeloid and is most frequently associated with exposure to domestic swine. Infection of native and prosthetic joints is a rarely reported manifestation. CASE PRESENTATION: We describe a case of E. rhusiopathiae prosthetic joint infection in a woman with a history of exposure to wild animals in the Canadian Arctic. Patient management involved a 1-stage surgical revision exchange with an antibiotic impregnated cement spacer and 6 weeks of intravenous penicillin G followed by 6 weeks of oral amoxicillin. Ten previously reported cases of E. rhusiopathiae joint infection are reviewed. Recent increases in mortality due to infection with this organism among host animal populations in the Canadian Arctic have generated concern regarding a potential increase in human infections. However, whole genome sequencing (WGS) of the organism was unable to identify a zoonotic origin for this case. CONCLUSIONS: Consideration should be given to E. rhusiopathiae as a cause of joint infections if the appropriate epidemiologic and host risk factors exist. Expanded use of WGS in other potential animal hosts and environmental sources may provide important epidemiologic information in determining the source of human infections.
