Changes in Inflammatory Cytokine Levels in Rectal Mucosa Associated With Neisseria gonorrheae and/or Chlamydia trachomatis Infection and Treatment Among Men Who Have Sex With Men in Lima, Peru.

BACKGROUND: Neisseria gonorrheae and Chlamydia trachomatis are associated with mucosal inflammation and human immunodeficiency virus 1 (HIV-1) transmission. We assessed levels of inflammatory cytokines in men who have sex with men (MSM) with and without rectal gonorrhea and/or chlamydia in Lima, Peru. METHODS: We screened 605 MSM reporting condomless receptive anal intercourse for rectal N. gonorrheae/C. trachomatis using nucleic acid testing. We identified 101 cases of gonorrhea and/or chlamydia and randomly selected 50 N. gonorrheae/C. trachomatis positive cases and matched 52 negative controls. We measured levels of IL-1ß, IL-6, IL-8, and TNF-α in rectal secretions. Tests for HIV-1, rectal N. gonorrheae/C. trachomatis, and mucosal cytokines were repeated after 3 and 6 months. Cytokine levels in cases and uninfected controls were compared using Wilcoxon rank-sum tests and linear regression. RESULTS: MSM with gonorrhea/chlamydia had elevated levels of all cytokines in rectal mucosa compared with matched controls (all P values <.001). Following antibiotic treatment there were no significant differences in cytokine levels at 3- or 6-month follow-up evaluations (all P values >.05). DISCUSSION: Rectal gonorrhea/chlamydia infection is associated with transient mucosal inflammation and cytokine recruitment. Our data provide proof of concept for rectal sexually transmitted infection screening as an HIV prevention strategy for MSM. Clinical Trials Registration. NCT03010020.

Using Self-Reported Sexual Positioning as an Indicator for Rectal Chlamydia and Gonorrhea Screening Among Men Who Have Sex With Men in China: A Missed Opportunity.

BACKGROUND: Rectal Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections among men who have sex with men (MSM) are escalating public health concerns. This study aimed to explore (1) the reliability of self-reported sexual positioning as an indicator for rectal CT and NG screening, and (2) factors associated with rectal CT and NG infections in Shenzhen, China. METHODS: A cross-sectional study was conducted in 2 settings in Shenzhen, China, from April 1, 2021, to March 31, 2022. Data on sociodemographic characteristics, sexual behaviors, and basic CT knowledge were collected. Urine and self-collected rectal swabs were collected for CT and NG testing. RESULTS: In total, 195 MSM participated in the study, and 5.1% tested positive for urogenital CT, 29.2% for rectal CT, 1.0% for urogenital NG, and 8.2% for rectal NG. Among those who reported exclusively insertive anal sex, 69.2% of CT infections and 85.7% of NG infections would have remained undetected with urine testing alone. Risk factors for rectal CT infection included engaging in both insertive and receptive anal sex, with a significant association found for coinfection with rectal NG. CONCLUSIONS: Self-reported sexual positioning was found to be an unreliable indicator for CT and NG screening, as a substantial proportion of infections would have remained undetected. The findings suggest that CT and NG screening in China should be offered to all MSM regardless of self-reported sexual positioning, and that the dual CT/NG testing is recommended.

High Prevalence of Rectal Chlamydia and Gonorrhea Among Men Who Have Sex With Men Who Do Not Engage in Receptive Anal Sex.

BACKGROUND: In the United States, annual screening for rectal gonorrhea and chlamydia is only recommended for men who report receptive anal sex (RAS), but other behaviors (e.g., rimming) may lead to rectal Chlamydia trachomatis and Neisseria gonorrhoeae acquisition. METHODS: We enrolled individuals assigned male sex at birth who reported sex with men and denied RAS in the past 2 years or reported RAS 1 to 2 years ago but were tested and treated since last RAS. Participants enrolled in-person at the Sexual Health Clinic in Seattle, Washington (December 2019-July 2022), or online (July 2021-March 2022). Participants completed a survey that asked about 13 non-RAS behaviors and self-collected a rectal swab for gonorrhea/chlamydia nucleic acid amplification testing. We used log binomial regression to estimate the prevalence of rectal gonorrhea/chlamydia (adjusted prevalence ratio [aPR]) by behavior, adjusting for all other behaviors. RESULTS: We enrolled 292 participants (247 in-person and 45 online); 277 (95%) had nucleic acid amplification testing results. Rectal gonorrhea/chlamydia test positivity was 14.1% overall: 10.5% for rectal chlamydia and 4.3% for rectal gonorrhea. Most participants (70%) reported ≥1 behavior that involved direct contact with their anus. We observed a higher risk of rectal chlamydia for those who did versus did not report perianal play at 12 months (aPR, 2.39; 95% confidence interval, 1.10-5.22) and 2 months (aPR, 2.21; 95% confidence interval, 1.02-4.79). This was the only behavior significantly associated with testing positive. CONCLUSIONS: Rectal C. trachomatis and N. gonorrhoeae prevalence was high among men who deny RAS, suggesting other possible routes of acquisition. Rectal screening for those who deny RAS should be made with careful consideration of individual- and population-level effects.

Prevalence of urinary dysfunction after minimally invasive surgery for deep rectosigmoid endometriosis.

PURPOSE: This study aimed to assess the prevalence and progression of lower urinary tract symptoms following laparoscopic surgery for deep-infiltrating endometriosis of the rectosigmoid and identify preoperative factors associated with worse postoperative outcomes. METHODS: Prospective, observational study. SETTINGS: single-center, referral hospital for endometriosis. Patients undergoing laparoscopic surgery for deep-infiltrating endometriosis of the rectosigmoid colon between October 2016 and October 2018. MAIN OUTCOME MEASURES: urinary function was assessed with the validated Portuguese language version of the International Prostate Symptom Score, which is also used in women. The score was collected before and after surgery. The Wilcoxon signed-rank test was used to compare pre and postoperative scores and the chi-square test compared symptoms categorized by severity. RESULTS: Fifty-three patients were assessed and 44 were included. Concerning urinary symptoms after surgery, the irritative symptoms prevailed over the obstructive ones. Additionally, 58.8% and 54.5% of the women reported moderate or severe symptoms at pre and postoperative, respectively. In at least one questionnaire category, the postoperative questionnaire scores increased in ten (22.7%) participants. A statistically significant difference was found comparing the changes from absent/mild to moderate/severe IPSS categories (P = 0.039). No significant changes were identified in any of the International Prostate Symptom Score pre and postoperatively (P = 0.876). CONCLUSIONS: There was a high prevalence of pre and postoperative urinary symptoms. Patients with preoperative moderate/severe International Prostate Symptom Score are at risk of persisting urinary dysfunction after surgery for rectosigmoid deep endometriosis.

"A Space Odyssey" on Laparoscopic Segmental Rectosigmoid Resection for Deep Endometriosis: A Seventeen-year Retrospective Analysis of Outcomes and Postoperative Complications among 3050 Patients Treated in a Referral Center.

STUDY OBJECTIVE: To evaluate the feasibility of laparoscopic rectosigmoid resection for bowel endometriosis (RSE), reporting surgical and short-term postoperative outcomes in a consecutive large series of patients. DESIGN: A retrospective cohort study. SETTING: Third-level national referral center for deep endometriosis (DE). PATIENTS: 3050 patients with symptomatic RSE requiring surgical treatment. INTERVENTIONS: Nerve-sparing laparoscopic resection for RSE perfomed by a multidisciplinary team. After collecting intraoperative surgical characteristics, postoperative complications were collected by evaluating the risk factors associated with their onset. MEASUREMENTS AND MAIN RESULTS: Clavien-Dindo IIIb postoperative complications were noted in 13.1% of patients, with anastomotic leakage and rectovaginal fistula accounting for 3.0% and 1.9%, respectively. Postoperative bladder impairment was observed in 13.9% of patients during hospital discharge but spontaneously decreased to 4.5% at the first evaluation after 30 days, alongside a statistically significant change towards global symptom improvement. Multivariate analyses were done to identify the risk factors for segmental bowel resection in terms of occurrence of postoperative major complications. Ultralow (≤5 cm from the anal verge), low rectal anastomosis (<8 cm, >5 cm), parametrectomy, vaginal resection, and previous surgeries seemed more related to anastomotic leakage, rectovaginal fistula, and bladder retention. CONCLUSIONS: Laparoscopic rectosigmoid resection for RSE seems an effective and feasible procedure. The surgical complication rate is not negligible but could be reduced by implementing a multidisciplinary approach, an endless improvement in nerve-sparing techniques and surgical anatomy, as well as technological enhancements. Real future challenges will be to reduce the time for the first diagnosis of DE and the likelihood of surgical indications.

The Natural History of Rectal Gonococcal and Chlamydial Infections: The ExGen Study.

BACKGROUND: The duration of rectal gonococcal and chlamydial infection remains unknown. This basic epidemiologic parameter is needed to understand transmission dynamics. METHODS: We conducted a prospective, longitudinal, observational cohort study of 140 men who have sex with men (MSM) at risk of gonorrhea and chlamydia acquisition. For 48 weeks, enrolled men collected rectal swabs (Aptima multi-test kit) at home and responded to an electronic survey about sexual behavior and health conditions weekly. Swabs remained untested until participants completed the study. We used Kaplan-Meier estimates to determine the median duration of infection, censoring infections for treatment, loss to follow-up, and end-of-study. We used log-rank test to compare duration of infection by human immunodeficiency virus (HIV) status, history of infection with gonorrhea or chlamydia, and coinfection with the other pathogen. RESULTS: 140 enrolled MSM contributed 70.5 person-years of follow-up. Eighteen men had 20 incident rectal gonococcal infections, which persisted for 2-23 weeks; 30% were censored for treatment. The estimated median duration of rectal gonorrhea was 9 weeks (95% confidence interval [CI]: 3-12 weeks). Twenty-four men experienced 32 rectal chlamydial infections, persisting between 2 and 42 weeks; 60% were censored. The estimated duration of rectal chlamydia was 13 weeks (95% CI: 6 weeks-undefined). There were no differences in the duration of rectal gonorrhea or chlamydia by HIV status, history of chlamydia/gonorrhea, or coinfection. CONCLUSIONS: On average, rectal gonorrhea and chlamydial infections last 2-3 months, although some infections persisted for 6-11 months. Further understanding into predictors of persistence is needed.

Rectal chlamydia infections: implications for reinfection risk, screening, and treatment guidelines.

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.

Association between rectal gonorrhoea and HIV incidence in men who have sex with men: a meta-analysis.

BACKGROUND: Incidence of rectal gonorrhoea (GC) has been hypothesised as a correlate of HIV exposure in prevention trials of men who have sex with men (MSM). High rectal GC incidence in MSM trials of new biomedical prevention drugs may provide supportive evidence for ongoing HIV risk. Empirical evidence of correlation between rectal GC and HIV incidence is needed to assess whether high rectal GC rates reliably correlate with high risk of HIV. METHODS: Rectal GC and HIV are routinely tested in sexual health clinics (SHCs) throughout England. Through routine surveillance data collected at visits to SHCs, we assessed HIV incidence and new rectal GC diagnoses in repeat visits by HIV-negative MSM between 2011 and 2018, predating widespread roll-out of pre-exposure prophylaxis. Meta-analysis regression assessed population-level association between HIV and rectal GC incidence over time. FINDINGS: Between 2011 and 2018, HIV and rectal GC incidence was assessed in 541 056 HIV-negative MSM attending SHCs in England. HIV incidence among MSM attending SHCs fell from 1.26/100 person-years (PYs) in 2011 to 0.28/100 PYs in 2018. Rectal GC rates increased from 3.5/100 PYs to 11.1/100 PYs over the same period. The rate of HIV incidence decreased by 22.3% for each percent increase in rectal GC (95% CI -30.8 to -14.7, p<0.001). INTERPRETATION: Among the population of MSM attending SHCs in England, rectal GC rates increased substantially while HIV incidence rates decreased between 2011 and 2018. HIV incidence likely decreased through expanded HIV testing, prompt antiretroviral treatment (ART) initiation and increased viral suppression in persons living with HIV, interventions that did not decrease rectal GC. Rectal GC may not be an ideal proxy for HIV incidence in trials, as HIV exposure risk is complex and context dependent, given effective HIV prevention interventions in MSM.

Universal lymphogranuloma venereum (LGV) testing of rectal chlamydia in men who have sex with men and detection of asymptomatic LGV.

BACKGROUND: Lymphogranuloma venereum (LGV) is caused by Chlamydia trachomatis serovars L1-L3. This study determined the positivity for LGV testing before and after introduction of universal LGV testing of positive rectal Chlamydia trachomatis samples in men who have sex with men (MSM). METHODS: From March 2015 to February 2018, MSM with rectal C. trachomatis were not routinely tested for LGV at the Melbourne Sexual Health Centre unless they had HIV or symptoms of proctitis. From February 2018, universal testing for LGV of all positive rectal C. trachomatis specimens in men over the age of 25 years, regardless of symptoms was undertaken. LGV positivity was defined as the detection of LGV-associated C. trachomatis serovars. RESULTS: There were 3429 and 4020 MSM who tested positive for rectal chlamydia in the selective and universal LGV-testing periods, respectively. Of the total 3027 assessable specimens in both periods, 97 (3.2%; 95% CI 2.6% to 3.9%) specimens tested positive for LGV. LGV positivity in the selective testing period was higher than in the universal testing period (6.6% (33/502) vs 2.5% (64/2525), p<0.001). The proportion of LGV cases that were asymptomatic increased from 15.2% (5/33) in the selective testing period to 34.4% (22/64) in the universal testing period (p=0.045). Of the 70 symptomatic LGV cases symptoms included rectal discharge (71.4%, n=45) and rectal pain (60.0%, n=42). CONCLUSION: Universal LGV testing of all positive rectal chlamydia samples in MSM compared with selective testing led to the detection of asymptomatic rectal LGV, which constituted 34% of rectal LGV cases.

Meningococcal disease and sexual transmission: urogenital and anorectal infections and invasive disease due to Neisseria meningitidis.

Neisseria meningitidis is an obligate human commensal bacterium that frequently colonises the upper respiratory tract. Person-to-person transmission occurs via direct contact or through dispersion of respiratory droplets from a carrier of the bacteria, and can lead to invasive meningococcal disease. Rare sporadic cases of meningococcal urogenital and anorectal infections, including urethritis, proctitis, and cervicitis, have been reported, typically following orogenital contact with an oropharyngeal meningococcal carrier. The resulting infections were clinically indistinguishable from infections caused by Neisseria gonorrhoeae. Over the past two decades, there have also been multiple outbreaks across North America and Europe of invasive meningococcal disease among men who have sex with men (MSM). The responsible meningococci belong to a highly virulent and predominantly serogroup C lineage, including strains that are able to express nitrite reductase and grow in anaerobic environments, such as the urogenital and anorectal tracts. More recently, a distinct clade within this lineage has expanded to cause urethritis predominantly among men who have sex with women. Evolutionary events giving rise to this clade included the loss of the ability to express a capsule, and acquisition of several gonococcal alleles, including one allele encoding a highly efficient gonococcal nitrite reductase. Members of the clade continue to acquire gonococcal alleles, including one allele associated with decreased antibiotic susceptibility. This evolution has implications for the clinical and public health management of those who are infected and their close contacts, in terms of both antibiotic treatment, and prevention through vaccination.

Lymphogranuloma venereum genovariants in men having sex with men in Italy.

OBJECTIVES: Lymphogranuloma venereum (LGV) is an STI caused by Chlamydia trachomatis serovars L1-L3. In Europe, the current epidemic is caused mainly by L2b genovariant, although increasing cases associated with other L2 variants have been reported. Here, we assessed the distribution of rectal LGV genovariants among men having sex with men (MSM) in Italy. METHODS: From 2016 to 2020, all the anorectal swabs collected from MSM attending the STI Clinic of St. Orsola-Malpighi Hospital in Bologna and positive for C. trachomatis were stored. LGV infection was confirmed by a pmpH PCR, and, subsequently, a fragment of the ompA gene was amplified and sequenced. Sequences were aligned to reference strains representing different LGV variants. RESULTS: LGV cases accounted for one-third of all chlamydial rectal infections with a total prevalence of 4.1% (76/1852). Total number of LGV cases per year remained constant. LGV was mainly found in symptomatic patients (>65%), older than 30 years, with a high burden of other STIs (63.7% HIV-positive, 35.5% with concurrent rectal gonorrhoea, 19.7% with early syphilis). A decreasing trend in HIV-LGV co-infection was noticed over time. Three main LGV genovariants were detected (L2f, 46.1%; L2b, 23.0%; L2-L2b/D-Da, 16.9%), together with other known L2b variants (mainly L2bV2 and L2bV4). Two novel L2b ompA variants with non-synonymous single-nucleotide polymorphisms were found. Over time, the percentage of L2f cases dropped gradually, with a significant increase in L2-L2b/D-Da cases (p=0.04). CONCLUSIONS: In our area, LGV is endemic among MSM with different circulating genovariants. Active surveillance and genotyping programmes are needed to reduce re-establishing of LGV infection.

Rectal Chlamydia trachomatis Infection: A Narrative Review of the State of the Science and Research Priorities.

ABSTRACT: Chlamydia trachomatis (CT) is the most commonly reported infection in the United States. Most chlamydial research to date has focused on urogenital infection, but a growing body of research has demonstrated that rectal chlamydia is a relatively common infection among clinic-attending men and women. We know that most rectal CT infections are asymptomatic, but the health implications of these infections, particularly for women, are unclear. In addition, there are key knowledge gaps related to the epidemiologic parameters of rectal chlamydia, the routes of acquisition, the duration of infection, and the clinical significance of a positive rectal CT test result. This lack of information has led to a blind spot in the potential role of rectal chlamydia in sustaining high levels of CT transmission in the United States. Furthermore, recent findings from animal models suggest that the immune response generated from gastrointestinal chlamydial infection can protect against urogenital infection; however, it remains to be determined whether rectal chlamydia similarly modulates anti-CT immunity in humans. This is a critical question in the context of ongoing efforts to develop a CT vaccine. In this narrative review, we summarize the state of the science for rectal chlamydia and discuss the key outstanding questions and research priorities in this neglected area of sexual health research.

Fertility in patients with untreated rectosigmoid endometriosis.

RESEARCH QUESTION: Several studies have investigated reproductive outcomes following surgical treatment of colorectal endometriosis, mainly segmental colorectal resection. This study examines pregnancy and live birth rates of women with rectosigmoid endometriosis not treated by surgery. DESIGN: A retrospective analysis of data collected between May 2009 and January 2020 related to 215 women affected by rectosigmoid endometriosis wishing to conceive. Patients had a diagnosis of rectosigmoid endometriosis by transvaginal ultrasonography and magnetic resonance imaging enema. Patients with estimated bowel stenosis >70% at computed tomographic colonography and/or subocclusive/occlusive symptoms were excluded. RESULTS: During the median length of follow-up of 31 months (range 13-63 months), the total pregnancy and live birth rates of the study population were 47.9% and 45.1%, respectively. Sixty-two women had a live birth after natural conception (28.8%; 95% confidence interval [CI] 22.8-35.6%) with a median time required to conceive of 10 months (range 2-34 months). Eighty-three women underwent infertility treatments (38.6%, 95% CI 32.1-45.5%); among these, 68 patients underwent IVF either directly (n = 51) or after intrauterine insemination (IUI) failure (n = 17). Time to conception was significantly higher in women having conceived by IVF than in those having conceived naturally (P < 0.001) or by IUI (P = 0.006). In patients undergoing IVF cycles, a worsening of some pain and intestinal symptoms was observed. CONCLUSIONS: At median follow-up of 31 months, women with rectosigmoid endometriosis have a 48% pregnancy rate. However, these patients must be referred to centres specialized in managing endometriosis to properly assess symptoms and degree of bowel stenosis.

Surgical Outcomes after Colorectal Surgery for Endometriosis: A Systematic Review and Meta-analysis.

OBJECTIVE: To assess the impact of type of surgery for colorectal endometriosis-rectal shaving or discoid resection or segmental colorectal resection-on complications and surgical outcomes. DATA SOURCES: We performed a systematic review of all English- and French-language full-text articles addressing the surgical management of colorectal endometriosis, and compared the postoperative complications according to surgical technique by meta-analysis. The PubMed, Clinical Trials.gov, Cochrane Library, and Web of Science databases were searched for relevant studies published before March 27, 2020. The search strategy used the following Medical Subject Headings terms: ("bowel endometriosis" or "colorectal endometriosis") AND ("surgery for endometriosis" or "conservative management" or "radical management" or "colorectal resection" or "shaving" or "full thickness resection" or "disc excision") AND ("treatment", "outcomes", "long term results" and "complications"). METHODS OF STUDY SELECTION: Two authors conducted the literature search and independently screened abstracts for inclusion, with resolution of any difference by 3 other authors. Studies were included if data on surgical management (shaving, disc excision, and/or segmental resection) were provided and if postoperative outcomes were detailed with at least the number of complications. The risk of bias was assessed according to the Cochrane recommendations. TABULATION, INTEGRATION, AND RESULTS: Of the 168 full-text articles assessed for eligibility, 60 were included in the qualitative synthesis. Seventeen of these were included in the meta-analysis on rectovaginal fistula, 10 on anastomotic leakage, 5 on anastomotic stenosis, and 9 on voiding dysfunction <30 days. The mean complication rate according to shaving, disc excision, and segmental resection were 2.2%, 9.7%, and 9.9%, respectively. Rectal shaving was less associated with rectovaginal fistula than disc excision (odds ratio [OR] = 0.19; 95% confidence interval [CI], 0.10-0.36; p <.001; I2 = 33%) and segmental colorectal resection (OR = 0.26; 95% CI, 0.15-0.44; p <.001; I2 = 0%). No difference was found in the occurrence of rectovaginal fistula between disc excision and segmental colorectal resection (OR = 1.07; 95% CI, 0.70-1.63; p = .76; I2 = 0%). Rectal shaving was less associated with leakage than disc excision (OR = 0.22; 95% CI, 0.06-0.73; p = .01; I2 = 86%). No difference was found in the occurrence of leakage between rectal shaving and segmental colorectal resection (OR = 0.32; 95% CI, 0.10-1.01; p = .05; I2 = 71%) or between disc excision and segmental colorectal resection (OR = 0.32; 95% CI, 0.30-1.58; p = .38; I2 = 0%). Disc excision was less associated with anastomotic stenosis than segmental resection (OR = 0.15; 95% CI, 0.05-0.48; p = .001; I2 = 59%). Disc excision was associated with more voiding dysfunction <30 days than rectal shaving (OR = 12.9; 95% CI, 1.40-119.34; p = .02; I2 = 0%). No difference was found in the occurrence of voiding dysfunction <30 days between segmental resection and rectal shaving (OR = 3.05; 95% CI, 0.55-16.87; p = .20; I2 = 0%) or between segmental colorectal and discoid resections (OR = 0.99; 95% CI, 0.54-1.85; p = .99; I2 = 71%). CONCLUSION: Colorectal surgery for endometriosis exposes patients to a risk of severe complications such as rectovaginal fistula, anastomotic leakage, anastomotic stenosis, and voiding dysfunction. Rectal shaving seems to be less associated with postoperative complications than disc excision and segmental colorectal resection. However, this technique is not suitable for all patients with large bowel infiltration. Compared with segmental colorectal resection, disc excision has several advantages, including shorter operating time, shorter hospital stay, and lower risk of postoperative bowel stenosis.

A Nationwide Multi-Center Questionnaire Survey on the Real-World State and Issues Regarding Post-Stroke Complications in Japan.

OBJECTIVES: Post-stroke complications affect stroke survivors across the world, although data on them are limited. We conducted a questionnaire survey to examine the real-world state and issues regarding post-stroke complications in Japan, which represents a super-aged society. MATERIALS AND METHODS: In 2018, a nationwide multi-center questionnaire survey was conducted in the top 500 Japanese hospitals regarding the number of stroke patients treated. Three questionnaires regarding post-stroke complications were mailed to the doctors responsible for stroke management. RESULTS: Responses were obtained from 251 hospitals (50.2%). The chief doctors responsible for stroke management answered the questionnaires. The number of stroke patients in the departments of neurology and neurosurgery was 338.3 ± 195.3 and 295.8 ± 121.8. Hospitals were classified using the categories secondary (n =142) and tertiary hospitals (n = 106); most hospitals were acute hospitals. Dementia was the most common complication (30.9%), followed by dysphagia (29.3%), and apathy (16.3%). Dementia was thought to be more common by neurologists than neurosurgeons, while apathy and bladder-rectal disorder were thought to be more common by neurosurgeons than neurologists (p = 0.001). The most difficult complication to treat was dysphagia (40.4%), followed by dementia (33.9%), epilepsy (4.1%), and fall (4.1%). Dementia was considered to lack clinical evidence regarding treatment (32.8%), followed by dysphagia (25.3%), and epilepsy (14.1%). Epilepsy was considered to lack clinical evidence among hospitals with a larger number of stroke cases (p = 0.044). CONCLUSION: This study revealed the current state and issues regarding post-stroke complications in Japan. Clinicians should be aware of the importance of post-stroke complications, although data on them remain unsatisfactory.

Correlations Between Human Immunodeficiency Virus (HIV) Infection and Rectal Gonorrhea Incidence in Men Who Have Sex With Men: Implications for Future HIV Preexposure Prophylaxis Trials.

Using published data, we found a direct correlation between the incidence of rectal gonorrhea and human immunodeficiency virus (HIV) infection in men who have sex with men who were not using oral preexposure prophylaxis. HIV incidence was predicted using rectal gonorrhea incidence as the determinant in regression analysis. The observed correlation suggest that rectal gonorrhea incidence can potentially serve as a predictor of HIV incidence. If confirmed with additional data, a quantitative correlation for incidence of the 2 infections could be useful in active-controlled HIV prevention trials where low HIV incidence is expected. Widespread improvements in treatment as prevention and gonorrhea control can negatively impact the correlation and its utility.

Gastrointestinal Bleeding in Patients With Coronavirus Disease 2019: A Matched Case-Control Study.

INTRODUCTION: Although current literature has addressed gastrointestinal presentations including nausea, vomiting, diarrhea, abnormal liver chemistries, and hyperlipasemia as possible coronavirus disease 2019 (COVID-19) manifestations, the risk and type of gastrointestinal bleeding (GIB) in this population is not well characterized. METHODS: This is a matched case-control (1:2) study with 41 cases of GIB (31 upper and 10 lower) in patients with COVID-19 and 82 matched controls of patients with COVID-19 without GIB. The primary objective was to characterize bleeding etiologies, and our secondary aim was to discuss outcomes and therapeutic approaches. RESULTS: There was no difference in the presenting symptoms of the cases and controls, and no difference in severity of COVID-19 manifestations (P > 0.05) was observed. Ten (32%) patients with upper GIB underwent esophagogastroduodenoscopy and 5 (50%) patients with lower GIBs underwent flexible sigmoidoscopy or colonoscopy. The most common upper and lower GIB etiologies were gastric or duodenal ulcers (80%) and rectal ulcers related to rectal tubes (60%), respectively. Four of the esophagogastroduodenoscopies resulted in therapeutic interventions, and the 3 patients with rectal ulcers were referred to colorectal surgery for rectal packing. Successful hemostasis was achieved in all 7 cases that required interventions. Transfusion requirements between patients who underwent endoscopic therapy and those who were conservatively managed were not significantly different. Anticoagulation and rectal tube usage trended toward being a risk factor for GIB, although it did not reach statistical significance. DISCUSSION: In COVID-19 patients with GIB, compared with matched controls of COVID-19 patients without GIB, there seemed to be no difference in initial presenting symptoms. Of those with upper and lower GIB, the most common etiology was peptic ulcer disease and rectal ulcers from rectal tubes, respectively. Conservative management seems to be a reasonable initial approach in managing these complex cases, but larger studies are needed to guide management.

Prevalence of lymphogranuloma venereum among anorectal Chlamydia trachomatis-positive MSM using pre-exposure prophylaxis for HIV.

OBJECTIVES: We evaluated the prevalence of lymphogranuloma venereum (LGV) in anorectal Chlamydia trachomatis-positive French men who have sex with men (MSM) using pre-exposure prophylaxis (PrEP) for HIV. Here, we describe the clinical, biological and behavioural characteristics of these patients. METHODS: Laboratories throughout French metropolitan areas performing routine testing for C. trachomatis sent positive anorectal specimens to the National Reference Centre for bacterial STIs for LGV real-time PCR targeting the pmpH gene. Identification of the C. trachomatis genovar was performed by ompA gene sequencing. For each patient, clinical, biological and sexual behaviour data were collected after obtaining written informed consent. RESULTS: In 2017, 486 anorectal C. trachomatis-positive specimens from MSM PrEP users were analysed. A strain of genovar L was detected in 91 cases (18.7%). Patients with LGV were significantly more symptomatic, had more sexual partners and more concurrent syphilis compared with their non-LGV counterparts. OmpA gene sequencing, successful in two-thirds of anorectal C. trachomatis-positive specimens, showed that the LGV cases were mainly of variant L2b (n=33), followed by genovar L2 (n=27) and genetic L2b ompA variants (n=16). In 11 cases, the results indicated the occurrence of genetic exchange between L and non-L genovars. CONCLUSIONS: LGV was diagnosed in 18.7% of anorectal C. trachomatis-positive specimens from French MSM using PrEP. LGV testing should be carried out for MSM diagnosed with chlamydia and with a large number of sexual partners, high-risk practices and anorectal symptoms. These patients should be presumptively treated as having LGV. This is the first surveillance study of LGV among MSM PrEP users and monitoring should continue.

Extragenital Mycoplasma genitalium infections among men who have sex with men.

OBJECTIVES: There are limited data on the prevalence of Mycoplasma genitalium (Mgen) coinfection with rectal chlamydia (Chlamydia trachomatis (CT)) and rectal gonorrhoea (Neisseria gonorrhoeae (NG)) infections and few studies examining the prevalence of pharyngeal Mgen in men who have sex with men (MSM). Using transcription-mediated amplification assay, this study aimed to determine the proportion of rectal CT and rectal NG infections in MSM who are coinfected with rectal Mgen, and the proportion of MSM with Mgen detected in the pharynx in order to inform clinical practice. METHODS: This was a cross-sectional study conducted at Melbourne Sexual Health Centre in Australia. Consecutively collected rectal swabs from MSM that tested positive for CT (n=212) or NG (n=212), and consecutively collected pharyngeal samples (n=480) from MSM were tested for Mgen using the Aptima Mycoplasma genitalium Assay (Hologic, San Diego). Samples were linked to demographic data and symptom status. RESULTS: Rectal Mgen was codetected in 27 of 212 rectal CT (13%, 95% CI 9 to 18) and in 29 of 212 rectal NG (14%, 95% CI 9 to 19) samples, with no difference in the proportion positive for Mgen. MSM with rectal CT/Mgen coinfection had more sexual partners than those with rectal CT monoinfection (mean 6 vs 11, p=0.06). MSM with rectal NG/Mgen coinfection were more likely to be HIV-positive than those with rectal NG monoinfection (OR=2.96, 95% CI 1.21 to 7.26, p=0.023). MSM with rectal CT/Mgen coinfection were more likely to be using pre-exposure prophylaxis than MSM with rectal NG/Mgen coinfection (OR 0.25, 95% CI 0.10 to 0.65, p=0.002). Pharyngeal Mgen was uncommon and detected in 8 of 464 samples (2%, 95% CI 1% to 3%). Pharyngeal Mgen was associated with having a rectal STI (OR=10.61, 95% CI 2.30 to 48.87, p=0.002), and there was a borderline association with being HIV-positive (p=0.079). CONCLUSION: These data indicate one in seven MSM treated for rectal CT or rectal NG will have undiagnosed Mgen that is potentially exposed to azithromycin during treatment of these STIs. Rectal Mgen coinfection was associated with specific risk factors which may inform testing practices. Pharyngeal Mgen was uncommon.

Extragenital Gonorrhea and Chlamydia Positivity and the Potential for Missed Extragenital Gonorrhea With Concurrent Urethral Chlamydia Among Men Who Have Sex With Men Attending Sexually Transmitted Disease Clinics-Sexually Transmitted Disease Surveillance Network, 2015-2019.

BACKGROUND: Extragenital gonorrhea (GC) and chlamydia (CT) are usually asymptomatic and only detected through screening. Ceftriaxone plus azithromycin is the recommended GC treatment; monotherapy (azithromycin or doxycycline) is recommended for CT. In urethral CT-positive/urethral GC-negative persons who are not screened extragenitally, CT monotherapy can lead to GC undertreatment and may foster the development of gonococcal antimicrobial resistance. We assessed urethral and extragenital GC and CT positivity among men who have sex with men (MSM) attending sexually transmitted disease clinics. METHODS: We included visit data for MSM tested for GC and CT at 30 sexually transmitted disease clinics in 10 jurisdictions during January 1, 2015, and June 30, 2019. Using an inverse-variance random effects model to account for heterogeneity between jurisdictions, we calculated weighted test visit positivity estimates and 95% confidence intervals (CI) for GC and CT at urethral and extragenital sites, and extragenital GC among urethral CT-positive/GC-negative test visits. RESULTS: Of 139,718 GC and CT test visits, we calculated overall positivity (GC, 16.7% [95% CI, 14.4-19.1]; CT, 13.3% [95% CI, 12.7-13.9]); urethral positivity (GC, 7.5% [95% CI, 5.7-9.3]; CT, 5.2% [95% CI, 4.6-5.8]); rectal positivity (GC, 11.8% [95% CI, 10.4-13.2]; CT, 12.6% [95% CI, 11.8-13.4]); and pharyngeal positivity (GC, 9.1% [95% CI, 7.9-10.3]; CT, 1.8% [95% CI, 1.6-2.0]). Of 4566 urethral CT-positive/GC-negative test visits with extragenital testing, extragenital GC positivity was 12.5% (95% CI, 10.9-14.1). CONCLUSIONS: Extragenital GC and CT were common among MSM. Without extragenital screening of MSM with urethral CT, extragenital GC would have been undetected and undertreated in approximately 13% of these men. Undertreatment could potentially select for antimicrobial resistance. These findings underscore the importance of extragenital screening in MSM.
