Prevalence of Mycoplasma genitalium and macrolide resistance in rectal and urine samples among men who have sex with men in Sweden.

OBJECTIVES: While Mycoplasma genitalium is reported as a common rectal infection among men who have sex with men (MSM), published data refer predominantly to urethral infections. Currently, most guidelines recommend M. genitalium testing from urine in men with symptomatic, non-gonococcal urethritis. Macrolide resistance-associated mutations (MRMs) among M. genitalium have increased during the last decade especially among MSM. We aim to demonstrate the prevalence and anatomical distribution of M. genitalium infection and MRM in urine and rectal specimens among MSM in Sweden. METHODS: In this cross-sectional study in 2019, paired urine and rectal samples from symptomatic and asymptomatic MSM attending a sexually transmitted infection clinic in the south of Sweden were screened for M. genitalium, presence of MRM, Neisseria gonorrhoeae, Chlamydia trachomatis, HIV and syphilis. RESULTS: The overall prevalence of M. genitalium was 10.5% (64 of 609), rectal samples 7.6% (46 of 609) and urine samples 3.9% (24 of 609) (p=0.007). Among M. genitalium-positive cases, single rectal and single urethral infection was detected in 62.5% (40 of 64) and 28.1% (18 of 64), respectively (p<0.0001). Infection at both sites was seen in 9.4% (6 of 64). The prevalence of MRM was 67.9% (19 of 28). M. genitalium was significantly associated with HIV (OR 2.60, 95% CI 1.14 to 5.88, p=0.02). Among the MSM, 7.4% (45 of 609) were infected with N. gonorrhoeae, 6.7% (41 of 609) with C. trachomatis, 7.1% (43 of 609) with HIV and 0.7% (4 of 609) with syphilis. CONCLUSIONS: In this study, among MSM, most infections with M. genitalium were detected as rectal mono infections. The prevalence of M. genitalium among MSM was almost twofold higher in rectal samples (7.6%) compared with urine samples (3.9%). The prevalence of macrolide resistance was high with no difference between urine and rectal samples.

Evaluation of a digital patient education programme in patients with coronary artery disease, a survey-based study.

INTRODUCTION: Patient education programmes focusing on risk factor modification and lifestyle changes are well established as part of cardiac rehabilitation in patients with coronary artery disease (CAD). As participation rates are low, digital patient education programmes (DPE) are interesting alternatives to increase access. Understanding patients' perceptions of DPE are important in terms of successful implementation in clinical practice but are not well known. Therefore, the aim of this study was to assess patients' perceptions of using a DPE in terms of end-user acceptance and usability, perceived significance for lifestyle changes and secondary preventive goal fulfilment in patients with CAD. METHODS: This was a cross-sectional survey-based study. The survey was distributed to all 1625 patients with acute coronary syndrome or chronic CAD with revascularisation, who were registered users of the DPE between 2020 and 2022 as part of cardiac rehabilitation. The survey contained 64 questions about e.g., acceptance and usability, perceived significance for making lifestyle changes and secondary preventive goal fulfilment. Patients who had never logged in to the DPE received questions about their reasons for not logging in. Data were analysed descriptively. RESULTS: A total of 366 patients (mean age: 69.1 ± 11.3 years, 20% female) completed the survey and among those 207 patients (57%) had used the DPE. Patients reported that the DPE was simple to use (80%) and improved access to healthcare (67-75%). A total of 69% of the patients were generally satisfied with the DPE, > 60% reported that the DPE increased their knowledge about secondary preventive treatment goals and approximately 60% reported having a healthy lifestyle today. On the other hand, 35% of the patients would have preferred a hospital-based education programme. Among the 159 patients (43%) who had never used the DPE, the most reported reason was a perceived need for more information about how to use the DPE (52%). CONCLUSIONS: This study shows an overall high level of patient acceptance and usability of the DPE, which supports its continued development and long-term role in cardiac rehabilitation in patients with CAD. Future studies should assess associations between participation in the DPE and clinical outcomes, such as secondary preventive goal fulfilment and hospitalisation.

Mycoplasma genitalium and Macrolide Resistance-associated Mutations in the Skåne Region of Southern Sweden 2015.

Mycoplasma genitalium is a sexually transmitted infection ordinarily treated with azithromycin. Emerging resistance to macrolide is linked to mutations in the 23S rRNA gene. We analysed the frequency of such mutations of M. genitalium isolates from patients that were symptomatic, and from sexual partners of symptomatic individuals, from October to December of 2015, in the Skåne Region of Sweden. Mutations were analysed by the use of DNA sequencing. Overall, 11.9% (145/1,311) and 17.0% (116/704) of females and males were positive for M. genitalium, respectively. Macrolide resistant mutations were detected in 13% (31/239) of M. genitalium isolates from first-test patient samples. Twenty-one (8.8%) and 10 (4.2%) of the isolates had point mutations of the 23S-gene at position 2072 and 2071, respectively. Two different M. genitalium isolates were detected simultaneously in two cases. In summary, we found a relatively low rate of macrolide-resistant M. genitalium in the region of Southern Sweden.

Human papillomavirus typing in reporting of condyloma.

BACKGROUND: Monitoring of condylomas is an early evidence of population effectiveness of human papillomavirus (HPV) vaccination programs. If reporting could include HPV typing, the contribution by vaccine HPV types to condyloma burden could be monitored. METHODS: A sentinel site for reporting of condyloma including HPV typing was established at the Centre for Sexual Health in Malmö, Sweden. In 2006 to 2009, when there were few HPV vaccines, 621 subjects with condyloma were reported and HPV genotyped. RESULTS: Ninety-four percent of the condylomas contained genital HPV types. Thirty-five different genital HPV types were identified, with HPV6 (62%), HPV16 (13%), and HPV11 (10%) being the most common. At least 1 of the 4 HPV types in the HPV6/11/16/18 vaccine was detected in 77%. High-risk HPV types were more common in females (45%) than among males (27%) (odds ratio, 1.9; confidence interval, 1.3-2.8). Extended testing among subjects initially negative for HPV found 21 patients with cutaneous types of HPV, including a novel type (HPV153). CONCLUSIONS: This report provides a baseline distribution of HPV types in condylomas before the introduction of an HPV vaccination program in this population. Human papillomavirus typing is feasible in routine condyloma reporting.

Clinical manifestations and epidemiology of the new genetic variant of Chlamydia trachomatis.

BACKGROUND: In 2006, a new genetic variant of Chlamydia trachomatis (nvCT) was discovered in Sweden. Clinical manifestations of this infection were studied in a high-risk population. METHODS: During 2007, a prospective case-control study on sexual lifestyle and urogenital infections was performed at the Centre for Sexual Health (CSH), affiliated to Malmo University Hospital. A total of 629 C. trachomatis positive cases and 1252 negative controls were included. At Malmo University Hospital, Department of Obstetrics and Gynecology, all cases of pelvic inflammatory disease (PID) were assessed and correlated to the prevalence of nvCT. RESULTS: Patients with nvCT or wild type C. trachomatis (wtCT) infection did not differ regarding their sexual lifestyle. Men with nvCT or wtCT infection did not differ in uro-genital symptoms or clinical findings. Women with nvCT infection reported painful urination (12.2% vs. 25.8%, P = 0.02) and were diagnosed with urethritis (11.1% vs. 40.0%, P = 0.04) less often than women with wtCT infection. The ratio of lower abdominal pain in women with nvCT infection was only half of that in women with wtCT infection (13.4% vs. 27.8%, P = 0.02). PID was detected in 0.8% of women with C. trachomatis infection in Malmo. All these cases were due to wtCT infection. CONCLUSIONS: Symptomatic urethral infection and lower abdominal pain was less common in women with nvCT as compared to wtCT. Infection with nvCT was more frequently asymptomatic suggesting a possible difference in virulence between the nvCT strain and the wtCT strain.
