RESUMEN

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.

RESUMEN

Chlamydia trachomatis (CT) is the leading cause of bacterial sexually transmitted diseases worldwide, which can cause diseases such as pelvic inflammatory disease, and cervical and fallopian tube inflammation, and poses a threat to human health. Rosmarinic acid (RosA) is an active ingredient of natural products with anti-inflammatory and immunomodulatory effects. This study aimed to investigate the role of RosA in inhibiting autophagy-regulated immune cells-CD8+ T cells via the Ras/Raf/MEK/ERK signaling pathway in a CT-infected mouse model. Mice were inoculated with CT infection solution vaginally, and the mechanistic basis of RosA treatment was established using H&E staining, flow cytometry, immunofluorescence, transmission electron microscopy, and western blot. The key factors involved in RosA treatment were further validated using the MEK inhibitor cobimetinib. Experimental results showed that both RosA and the reference drug azithromycin could attenuate the pathological damage to the endometrium caused by CT infection; flow cytometry showed that peripheral blood CD8+ T cells increased after CT infection and decreased after treatment with RosA and the positive drug azithromycin (positive control); immunofluorescence showed that endometrial CD8 and LC3 increased after CT infection and decreased after RosA and positive drug treatment; the results of transmission electron microscopy showed that RosA and the positive drug azithromycin inhibited the accumulation of autophagosomes; western bolt experiments confirmed the activation of autophagy proteins LC3Ⅱ/Ⅰ, ATG5, Beclin-1, and p62 after CT infection, as well as the inhibition of Ras/Raf/MEK/ERK signaling. RosA and azithromycin inhibition of autophagy proteins activates Ras/Raf/MEK/ERK signaling. In addition, the MEK inhibitor cobimetinib attenuated RosA's protective effect on endometrium by further activating CD8+ T cells on a CT-induced basis, while transmission electron microscopy, immunofluorescence, and western blots showed that cobimetinib blocked ERK signals activation and further induced phagocytosis on a CT-induced basis. These data indicated that RosA can activate the Ras/Raf/MEK/ERK signaling pathway to inhibit autophagy, and RosA could also regulate the activation of immune cells-CD8+T cells to protect the reproductive tract of CT-infected mice.

RESUMEN

Introduction: Vitamin D deficiency is the most common nutritional deficiency worldwide. Chronic vitamin D deficiency causes immune system dysfunction, which increases susceptibility to pathogens such as bacteria, especially intracellular parasites, and viruses. Chlamydia trachomatis (C. t) is an obligate intracellular parasitic bacterium that causes a variety of sequelae. We speculated that vitamin D might be associated with C. t infection. This study aimed to address this gap in knowledge by investigating the relationship between vitamin D and C. t infection using both in vitro and in vivo models. Methods and results: The addition of calcitriol to McCoy cell culture in vitro delayed and reduced the quantity and volume of inclusions compared to the control group. Macrophages of peritoneally lavaged mice co-cultured with McCoy decreased the infection rate and delayed the appearance of inclusions. In mice models of vitamin D deficiency, mice in the VD-group exhibited more severe genital tract inflammation and a longer duration of infection after inoculation with C. t in the genital tract. Supplementing these mice with vitamin D3 during treatment enhanced the therapeutic effect of antibiotics. We also conducted a case-control study involving 174 C. t-positive patients (95 males and 79 females) and 380 healthy volunteers (211 males and 169 females) aged 20-49 from January 2016 to March 15, 2017. Serum 25-(OH)D concentration was measured by assessing morning fasting blood samples of healthy volunteers and C. t-positive patients 1 day before antibiotic treatment and the next day after one course of treatment. The patients were followed up for 1 month and evaluated for recovery. The results showed that vitamin D deficiency was a risk factor for C. t infection and treatment failure. Conclusion: In summary, findings from experimental and clinical studies indicate a close association between vitamin D levels and C. t infection and treatment outcomes. Given the affordability and safety of vitamin D, both healthy individuals and patients should focus on vitamin D intake. Vitamin D supplementation could enhance treatment success and should be used as an adjunctive therapy alongside antibiotic therapy for C. t infections, pending confirmation in larger, prospective, randomized controlled trials.

RESUMEN

OBJECTIVES: Sexually transmitted infection (STI) diagnosis is complicated as these infections can present with lower genitourinary tract symptoms (LGUTS) that overlap with other disorders, i.e. urinary tract infections (UTIs). The study's objective was to determine potential missed STI diagnoses from patients presenting with LGUTS in the US between January 2010 and December 2019. METHODS: The de-identified insurance claims data from the IBM® MarketScan® Research Databases were collected from patients (14-64 years old) who presented with LGUTS, which could be caused by an STI. A 'GAP' cohort was created, consisting of episodes with potentially delayed STI (Chlamydia trachomatis [CT]/Neisseria gonorrhoeae [NG]) treatment. The intention was to capture episodes where an STI was not initially suspected. Four subgroups were defined depending on the treatment received (fluoroquinolone; azithromycin and/or doxycycline; cephalosporins; gentamicin and azithromycin). RESULTS: The GAP cohort consisted of 833,574 LGUTS episodes from the original cohort (23,537,812 episodes). Post-index CT/NG testing was carried out for 4.6% and 5.4% of the episodes from men and women, respectively. There were ≥2 return visits for 16.1% and 15.8% of the episodes from men and women, respectively. A substantial percentage of episodes from men (52.1%) and women (68.3%) were diagnosed with a UTI and/or acute cystitis at the index prior to receiving post-index STI treatment. Other top conditions diagnosed at index for men were dysuria (25.8% of the episodes), orchitis/epididymitis (14.3% of the episodes), and acute prostatitis (10.1% of the episodes), and for women were dysuria (24.2% of the episodes), vaginitis/vulvitis/vulvovaginitis (11.7% of the episodes), and cervicitis (3.3% of the episodes). CONCLUSION: These findings highlight delayed STI antibiotic treatment and low rates of CT/NG testing, suggesting late STI consideration and suboptimal diagnosis. Additionally, our study illustrates the importance of accurately diagnosing and treating STIs in patients with LGUTS and associated conditions, to avoid antibiotic misuse and complications from delayed administration of appropriate treatment.

RESUMEN

Chlamydiosis remains the leading infectious disease and is one of the key factors responsible for the dramatic reduction of koala populations in South-East Queensland (SEQ) and New South Wales (NSW) regions of Australia. Possible infection outcomes include blindness, infertility, painful cystitis, and death if left untreated. Studies have reported the treatment efficacy of chloramphenicol and doxycycline, which are the two most commonly administered treatments in diseased koalas, in clinical settings. However, none have directly compared the treatment efficacy of these antibacterials on koala survival. A retrospective study was essential to identify any relationships between the demographical information, and the animals' responses to the current treatment regimens. Associations were explored between six explanatory (sex; maturity; location; clinical signs, treatment; treatment duration) and two outcome variables (survival; post-treatment PCR). Results showed that female koalas had a statistical trend of lower odds of surviving when compared to males (OR = 0.36, p = 0.05). Koalas treated with chloramphenicol for ≥ 28 days had greater odds of surviving than when treated for < 28 days (OR = 8.8, p = 0.02), and those koalas administered doxycycline had greater odds of testing PCR negative when compared to chloramphenicol treatments (OR = 5.45, p = 0.008). There was no difference between the antibacterial treatments (chloramphenicol, doxycycline, and mixed/other) and the survival of koalas. Female koalas had greater odds of exhibiting UGT signs only (OR = 4.86, p < 0.001), and also greater odds of having both ocular and UGT clinical signs (OR = 5.29, p < 0.001) when compared to males. Of the koalas, 28.5% initially had no clinical signs but were PCR positive for C. pecorum. This study enables further understanding of the complex nature between chlamydial infection and response to antibacterial treatment.

RESUMEN

BACKGROUND: Alternative approaches to syndromic management are needed to reduce rates of sexually transmitted infections (STIs) in resource-limited settings. We investigated the impact of point-of-care (POC) versus central laboratory-based testing on STI treatment initiation and STI adverse event (STI-AE) reporting. METHODS: We used Kaplan-Meier and Cox regression models to compare times to treatment initiation and STI-AE reporting among HVTN702 trial participants in South Africa. Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) were diagnosed POC at eThekwini clinic and in a central laboratory at Verulam/Isipingo clinics. All clinics used POC assays for Trichomonas vaginalis (TV) testing. RESULTS: Among 959 women (median age, 23 [interquartile range, 21-26] years), median days (95% confidence interval [95%CI]) to NG/CT treatment initiation and NG/CT-AE reporting were 0.20 (.16-.25) and 0.24 (.19-.27) at eThekwini versus 14.22 (14.12-15.09) and 15.12 (13.22-21.24) at Verulam/Isipingo (all P < .001). Median days (95%CI) to TV treatment initiation and TV-AE reporting were 0.17 (.12-.27) and 0.25 (.20-.99) at eThekwini versus 0.18 (.15-.2) and 0.24 (.15-.99) at Verulam/Isipingo (all P > .05). Cox regression analysis revealed that NG/CT treatment initiation (adjusted hazard ratio [aHR], 39.62 [95%CI, 15.13-103.74]) and NG/CT-AE reporting (aHR, 3.38 [95%CI, 2.23-5.13]) occurred faster at eThekwini versus Verulam/Isipingo, while times to TV treatment initiation (aHR, 0.93 [95%CI, .59-1.48]) and TV-AE reporting (aHR, 1.38 [95%CI, .86-2.21]) were similar. CONCLUSIONS: POC testing led to prompt STI management with potential therapeutic and prevention benefits, highlighting its utility as a diagnostic tool in resource-limited settings.

RESUMEN

Chlamydia trachomatis, a parasitic intracellular bacterium, is a major human pathogen that causes millions of trachoma, sexually transmitted infections, and pneumonia cases worldwide. Previously, peptidomimetic inhibitors consisting of a hydrophobic dipeptide derivative exhibited significant inhibitory effects against chlamydial growth. Based on this finding, this study showed that both bortezomib (BTZ) and ixazomib (IXA), anticancer drugs characterized by proteasome inhibitors, have intensive inhibitory activity against Chlamydia. Both BTZ and IXA consisted of hydrophobic dipeptide derivatives and strongly restricted the growth of Chlamydia (BTZ, IC50 = 24 nM). In contrast, no growth inhibitory effect was observed for other nonintracellular parasitic bacteria, such as Escherichia coli. BTZ and IXA appeared to inhibit chlamydial growth bacteriostatically via electron microscopy. Surprisingly, Chlamydia-infected cells that induced a persistent infection state were selectively eliminated by BTZ treatment, whereas uninfected cells survived. These results strongly suggested the potential of boron compounds based on hydrophobic dipeptides for treating chlamydial infections, including persistent infections, which may be useful for future therapeutic use in chlamydial infectious diseases.

RESUMEN

Chlamydia are obligate intracellular bacteria that reside within a membrane-bound compartment called the chlamydial inclusion inside a eukaryotic host cell. These pathogens have a complex biphasic developmental cycle, which involves conversion between a replicating, but noninfectious, reticulate body (RB) and an infectious elementary body (EB). Small molecule inhibitors have been reported to have deleterious effects on the intracellular Chlamydia infection, but these studies have typically been limited in terms of assays and time points of analysis. We compared published and novel inhibitors and showed that they can differentially alter inclusion size, chlamydial number and infectious EB production, and that these effects can vary over the course of the intracellular infection. Our results provide the justification for analysis with multiple assays performed either at the end of the infection or over a time course. We also show that this approach has the potential to identify the particular step in the developmental cycle that is impacted by the inhibitor. We furthermore propose that the magnitude of inhibitor-induced progeny defects are best quantified and compared by using a new value called maximal progeny production (Progenymax). As a demonstration of the validity of this systematic approach, we applied it to inhibitors of Akt and AMPK, which are host kinases involved in lipid synthesis and cholesterol trafficking pathways. Both inhibitors reduced EB production, but Akt disruption primarily decreased RB-to-EB conversion while AMPK inhibition paradoxically enhanced RB replication. IMPORTANCE Chlamydia is the most reported cause of bacterial, sexually transmitted infection in the United States. This bacterium infects human cells and reproduces within a cytoplasmic inclusion via an unusual developmental cycle involving two specialized chlamydial forms. Small molecule compounds have been reported to negatively affect the inclusion as well as chlamydial replication and infectious progeny production, but we showed that these effects can be discordant and vary over the course of the 48- to 72-hour long intracellular infection. We propose approaches to analyze these nonuniform effects, including measurements at the end of the intracellular infection, and more detailed analysis with multiple assays performed over the course of the developmental cycle. We then applied this approach to investigate and compare the anti-chlamydial effects of two inhibitors that alter host lipid synthesis and cholesterol trafficking.

RESUMEN

AIM: To report two atypical inclusion conjunctivitis cases due to Chlamydia trachomatis in young adults. METHOD: Transcription mediated amplification for C. trachomatis was performed using Aptima Combo 2 Assay (Hologic, Spain). RESULTS: The first patient was managed as an orbital disorder because he had unilateral location, and ptosis was observed. Orbital nuclear magnetic resonance revealed normal results, and conjunctival biopsy did not indicate significant results. For the second patient, thyroid eye disease was suspected, but the orbital nuclear magnetic resonance revealed normal results. Conjunctival exudate samples were collected and sent to the Microbiology Laboratory where C. trachomatis was confirmed. Both patients demonstrated a great improvement with oral azithromycin 1 g. CONCLUSION: Inclusion conjunctivitis could present as unspecified unilateral or bilateral chronic conjunctivitis. Thus, suspecting it would be important in order to prevent spread and wasting diagnostic resources.

RESUMEN

Importance: Approximately 1 in 5 adults in the US had a sexually transmitted infection (STI) in 2018. This review provides an update on the epidemiology, diagnosis, and treatment of gonorrhea, chlamydia, syphilis, Mycoplasma genitalium, trichomoniasis, and genital herpes. Observations: From 2015 to 2019, the rates of gonorrhea, chlamydia, and syphilis increased in the US; from 1999 to 2016, while the rates of herpes simplex virus type 1 (HSV-1) and HSV-2 declined. Populations with higher rates of STIs include people younger than 25 years, sexual and gender minorities such as men and transgender women who have sex with men, and racial and ethnic minorities such as Black and Latinx people. Approximately 70% of infections with HSV and trichomoniasis and 53% to 100% of extragenital gonorrhea and chlamydia infections are asymptomatic or associated with few symptoms. STIs are associated with HIV acquisition and transmission and are the leading cause of tubal factor infertility in women. Nucleic acid amplification tests have high sensitivities (86.1%-100%) and specificities (97.1%-100%) for the diagnosis of gonorrhea, chlamydia, M genitalium, trichomoniasis, and symptomatic HSV-1 and HSV-2. Serology remains the recommended method to diagnose syphilis, typically using sequential testing to detect treponemal and nontreponemal (antiphospholipid) antibodies. Ceftriaxone, doxycycline, penicillin, moxifloxacin, and the nitroimidazoles, such as metronidazole, are effective treatments for gonorrhea, chlamydia, syphilis, M genitalium, and trichomoniasis, respectively, but antimicrobial resistance limits oral treatment options for gonorrhea and M genitalium. No cure is available for genital herpes. Effective STI prevention interventions include screening, contact tracing of sexual partners, and promoting effective barrier contraception. Conclusions and Relevance: Approximately 1 in 5 adults in the US had an STI in 2018. Rates of gonorrhea, chlamydia, and syphilis in the US have increased, while rates of HSV-1 and HSV-2 have declined. Ceftriaxone, doxycycline, penicillin, moxifloxacin, and the nitroimidazoles are effective treatments for gonorrhea, chlamydia, syphilis, Mycoplasma genitalium, and trichomoniasis, respectively, but antimicrobial resistance limits oral therapies for gonorrhea and Mycoplasma genitalium, and no cure is available for genital herpes.

RESUMEN

BACKGROUND: We assessed the cost-effectiveness of the Check It program, a novel community-based chlamydia screening and expedited partner treatment program for young Black men conducted in New Orleans since 2017. METHODS: We implemented a probabilistic cost-effectiveness model using a synthetic cohort of 16 181 men and 13 419 women intended to simulate the size of the Black, sexually active population in New Orleans ages 15-24 years. RESULTS: The Check It program cost $196 838 (95% confidence interval [CI]: $117 320-$287 555) to implement, saved 10.2 quality-adjusted life-years (QALYs; 95% CI: 7.7-12.7 QALYs), and saved $140 950 (95% CI: -$197 018 to -$105 620) in medical costs per year. The program cost $5468 (95% CI: cost saving, $16 717) per QALY gained. All iterations of the probabilistic model returned cost-effectiveness ratios less than $50 000 per QALY gained. CONCLUSIONS: The Check It program (a bundled seek, test, and treat chlamydia prevention program for young Black men) is cost-effective under base case assumptions. Communities where Chlamydia trachomatis rates have not declined could consider implementing a similar program.

RESUMEN

PURPOSE OF REVIEW: Rectal chlamydia is a prevalent sexually transmissible infection in both men who have sex with men (MSM) and in women. Screening is recommended for MSM but remains controversial for women. The optimal treatment for rectal chlamydia is now conclusive but interpreting and managing positive results remains challenging. Infections among MSM are increasing and strategies are needed to reduce incident infections. This review summarizes recent developments for the screening and management of rectal chlamydia and its implications on reinfection. RECENT FINDINGS: Reinfections in MSM may be occurring due to resumption of sex soon after treatment whereas repeat infections in women may occur due to autoinoculation in the absence of sex. Doxycycline is now first-line treatment but its role in chemoprophylaxis remains unclear. False positive results remain an issue, but the development of viability assays may prove useful in future to determine true infections. SUMMARY: Doxycycline is the first-line treatment for rectal chlamydia and in women may prevent infections at the urogenital site. Viability assays can help to reduce antibiotic use once developed. The role of routine screening of rectal chlamydia in women remains unclear and this debate may soon include asymptomatic infections in MSM.

RESUMEN

Pelvic Inflammatory Disease is a topic included in the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. Pelvic inflammatory disease is an upper female genital tract acute infection due to canalicular spread of endogenous cervicovaginal microorganisms and especially the sexually transmitted microorganisms. Standing out among the etiological agents involved are Chlamydia trachomatis and Neisseria gonorrhoeae. The main sequelae are chronic pelvic pain, infertility, and ectopic pregnancy. Clinical diagnosis is the most important practical approach. Antibiotic treatment must start immediately after the clinical suspicion. Guidelines for health service managers and health professionals on diagnostic tests, treatment, follow-up, counseling, notification, handling sexual partners and special populations are described. Given the increased availability of the molecular biology techniques in Brazil, C. trachomatis and N. gonorrhoeae screening are recommended as a disease prevention strategy. Pelvic inflammatory disease is one of the most significant sexually transmitted infections, and in most cases, it is a main consequence of cervicitis.

RESUMEN

BACKGROUND: Expedited partner treatment (EPT) is effective for preventing sexually transmitted infection recurrence, but concerns about intimate partner violence and missed opportunities for human immunology virus (HIV) testing have limited its use in African settings. METHODS: We conducted a pilot prospective evaluation of EPT among adolescent girls and young women (AGYW) accessing HIV preexposure prophylaxis in an implementation project in Kisumu, Kenya. Those with etiologic diagnosis of Chlamydia trachomatis and Neisseria gonorrhoeae were treated and given the option of delivering sexually transmitted infection medication and HIV self-test kits to their current sexual partner(s). At enrollment, we assessed their reasons for declining. Three months after they delivered medication and kits to the partner(s), we assessed their reasons for failing to deliver medication and kits to their partner and reported partner's reactions. RESULTS: Between September 2018 and March 2020, 63 AGYW were enrolled. The majority (59/63 [94%]) accepted EPT, and 50 (79%) of 63 partner HIV self-testing (HIVST). Three quarters (46/59) of those accepting EPT returned for the assessment visit with 41 (89%) of 46 successfully delivering medication to 54 partners, of whom 49 (91%) used it. Seventy percent (35/50) who took partner HIVST kits returned for the assessment, with 80% (28/35) reporting providing kits to 40 partners, of whom 38 (95%) used it. Reported barriers to EPT and partner HIVST uptake among women who declined included anticipated fear that their partner could become angry or violent and loss of relationship. CONCLUSIONS: Both EPT and partner HIVST were acceptable despite noted barriers among Kenyan AGYW with etiologic diagnosis of Chlamydia trachomatis/Neisseria gonorrhoeae and their partners.

RESUMEN

Fitz-Hugh-Curtis syndrome is a complication to pelvic inflammatory disease causing perihepatitis as described in this case report. A 21-year-old woman was admitted to the hospital due to pain under the right upper quadrant and febrility. Gallstones and pyelonephritis were ruled out. The Chlamydia test came back positive, and the patient had an elevated cancer antigen 125-level. She was suspected to have Fitz-Hugh-Curtis syndrome. On a second look on the ultrasound scan of the liver the capsule was seen to have a characteristic three-layered appearance. The patient was treated with doxycycline. On follow-up she was asymptomatic, and the laboratory parameters were normalised.

RESUMEN

PURPOSE: Adolescents and young adults have the highest prevalence of sexually transmitted infections (STIs), accounting for more than 50% of all reported infections. An especially high-risk group includes adolescents in juvenile or correctional facilities. METHODS: This retrospective analysis was conducted at the only juvenile detention facility in the State of Hawai'i from 2014 to 2017. Adolescents aged 12-17 years were offered STI screening and/or presumptive treatment at the time of medical evaluation. RESULTS: Of 2,208 adolescents offered voluntary testing, 461 males and 372 females agreed to be tested for Chlamydia trachomatis and Neisseria Gonorrhea. Acceptance did not vary by age; females chose testing more often than males (67.4% vs. 27.8%; p < .0001). Females were also more likely to accept presumptive treatment (22.8% vs. 8.8%; p < .0001). In tested youth, STIs were prevalent in 24% of females and 10% of males. Before leaving the detention facility, only half the STIs in females and only 39% of male STI infections had been treated. CONCLUSIONS: There was a high prevalence of STIs in both males and females admitted to this juvenile detention facility, with fewer than half the documented infections being treated before discharge. This indicates a need for universal and timely testing to allow the treatment of those infected. If for whatever reason rapid testing cannot be obtained, presumptive treatment offers a pragmatic approach to treatment and infection control.

RESUMEN

Preterm birth is a major public health problem, occurring in more than half a million births per year in the United States. A number of maternal conditions have been recognized as risk factors for preterm birth, but for the majority of cases, the etiology is not completely understood. Chlamydia trachomatis is one of the most prevalent sexually transmitted infections in the world. However, its role in adverse pregnancy outcome in women is still debated. In order to determine if genitourinary tract infection with C. trachomatis during pregnancy was associated with preterm birth, we conducted a case-control study on women who delivered at Boston Medical Center, an urban "safety-net" hospital that serves a socioeconomically disadvantaged and racially diverse population. Women with known risk factors for preterm birth or immune suppression were excluded. Variables collected on enrolled subjects included demographics; diagnosis of C. trachomatis during or prior to pregnancy; tobacco, alcohol, and illicit substance use; gestational age; and birthweight and gender of the newborn. We also collected urine for chlamydia testing at the time of delivery and placental biopsies for nucleic acid amplification and histological studies. A total of 305 subjects were enrolled: 100 who delivered preterm and 205 who delivered full term. Among those subjects, we identified 19 cases of pregnancy-associated C. trachomatis infection: 6/100 preterm and 13/205 full term, a difference which was not statistically significant. Only two cases of untreated chlamydia infection were identified postpartum, and both occurred in women who delivered at term. We conclude that genitourinary tract infection with C. trachomatis during pregnancy, when appropriately treated, is not associated with preterm birth.

RESUMEN

OBJECTIVES: In 2016, WHO estimated 376 million new cases of the four main curable STIs: gonorrhoea, chlamydia, trichomoniasis and syphilis. Further, an estimated 290 million women are infected with human papillomavirus. STIs may lead to severe reproductive health sequelae. Low-income and middle-income countries carry the highest global burden of STIs. A large proportion of urogenital and the vast majority of extragenital non-viral STI cases are asymptomatic. Screening key populations and early and accurate diagnosis are important to provide correct treatment and to control the spread of STIs. This article paints a picture of the state of technology of STI point-of-care testing (POCT) and its implications for health system integration. METHODS: The material for the STI POCT landscape was gathered from publicly available information, published and unpublished reports and prospectuses, and interviews with developers and manufacturers. RESULTS: The development of STI POCT is moving rapidly, and there are much more tests in the pipeline than in 2014, when the first STI POCT landscape analysis was published on the website of WHO. Several of the available tests need to be evaluated independently both in the laboratory and, of particular importance, in different points of care. CONCLUSION: This article reiterates the importance of accurate, rapid and affordable POCT to reach universal health coverage. While highlighting the rapid technical advances in this area, we argue that insufficient attention is being paid to health systems capacity and conditions to ensure the swift and rapid integration of current and future STI POCT. Unless the complexity of health systems, including context, institutions, adoption systems and problem perception, are recognised and mapped, simplistic approaches to policy design and programme implementation will result in poor realisation of intended outcomes and impact.
