Retrospective Review of Gonococcal and Chlamydial Cases of Epididymitis at 2 Canadian Sexually Transmitted Infection Clinics, 2004-2014.

Fifty-seven cases of gonococcal and chlamydial infections complicated by acute epididymitis seen at 2 Alberta STI clinics from 2004 to 2014 were reviewed. The majority responded to treatment recommended by national guidelines. Three of 6 treatment failures were not treated according to guidelines.

Trichomonas vaginalis Prevalence and Correlates in Women and Men Attending STI Clinics in Western Canada.

Trichomonas vaginalis prevalence (2.8%) in female sexually transmitted infection clinic attendees was within the prevalence of chlamydia (5.8%) and gonorrhea (1.8%), while being very low for male attendees (0.2%). Correlates among women were indigenous ethnicity, other ethnicity, and being symptomatic.

A Retrospective Review of Treatment Failures Using Azithromycin and Doxycycline in the Treatment of Rectal Chlamydia Infections in Women and Men Who Have Sex With Men.

We examined the prevalence of rectal chlamydia treatment failures in men who have sex with men and women attending Alberta sexually transmitted infection clinics. Among those completing a test of cure, there was no significant difference among patients treated initially with azithromycin (treatment failure, 39/460 [8.5%]; 95% confidence interval, 5.9%-11.0%) compared with patients treated with doxycycline (0/16; 95% confidence interval, 0%-0.2%; P = 0.63).

Impact of Introducing Triage Criteria for Express Testing at a Canadian Sexually Transmitted Infection Clinic.

The implementation of express testing in an sexually transmitted infection (STI) clinic reduced the length of visit time compared with other visit types and increased the proportion of STIs diagnosed at clinic visits. Express testing did not impact the time to treatment for asymptomatic patients diagnosed as having an STI.

Prevalence and antibiotic resistance of Mycoplasma genitalium among STI clinic attendees in Western Canada: a cross-sectional analysis.

OBJECTIVES: To determine the prevalence and correlates of Mycoplasma genitalium (MG) infection among men and women, determine the prevalence of gene mutations conferring resistance and compare test performance of female specimen types. METHODS: A cross-sectional study was conducted on specimens collected for gonorrhoea (NG, Neisseria gonorrhoeae) and chlamydia (CT, Chlamydia trachomatis) among male and female Alberta STI clinic attendees using the M. genitalium transcription-mediated amplification-research use only test. Positive specimens were sequenced for 23SrRNA, parC and gyrA genes. Gender-stratified analysis compared test results using χ2 or Fisher's exact test, Mann-Whitney U test and logistic regression. Female endocervical and urine specimens were compared. RESULTS: A total of 2254 individuals were tested; 53.8% (n=1212) were male. Male prevalence of MG was 5.3%; CT was 5.9% and NG was 1.8%. Correlates of male infection were a non-gonococcal urethritis diagnosis and NG coinfection. MG prevalence for women was 7.2%; CT was 5.8% and NG was 1.8%. Correlates of female infection were younger age, Indigenous/Other ethnicity and CT/NG coinfection. Nearly two-thirds of eligible specimens had mutations associated with macrolide resistance and 12.2% of specimens had a parC mutation signifying possible moxifloxacin resistance. There was high concordance (98.1%) of results between urine and endocervical swabs. CONCLUSIONS: The high prevalence of MG relative to CT and NG supports the incorporation of MG testing into routine sexually transmissible infection screening. The high rate of resistance to macrolides and moxifloxacin raises concerns about treatment options. The good concordance of results between urine and endocervical swabs supports the use of female urine specimens for testing.
