Background and Objectives: Chlamydia trachomatis is a sexually transmitted organism and an important public health problem in the sexually active age group. Limited studies are found regarding the prevalence of Chlamydia trachomatis in Nepal. Moreover, no study in Nepal reports the association of Chlamydia and HIV infection. The current study attempts to determine the burden of Chlamydia on HIV positive patients. Material and Methods: A total of 117 HIV positive patients visiting a HIV clinic in Kathmandu, were screened for Chlamydia infection. For this, Urine samples were collected and analyzed using the Multiplex polymerase chain reaction technique (MPCR) and Agarose gel electrophoresis. DNA isolation was performed using QIAamp DNA and Blood mini kit handbook protocol. Results: C. trachomatis was detected in 4.27% of the total 117 HIV patients. Out of positive cases 60% were males and 40% were females. However, Chlamydia is found more prevalent among females (6.89%) than in males (3.4%). Eighty percent of positive cases were asymptomatic. Conclusion: Chlamydia infection was found less commonly among studied patients and most of those cases were asymptomatic. So there is difficulty in timely detection of C. trachomatis and track the clinical sequel, which might be devastating. Hence, routine checkup is recommended for all suspected cases for timely management of the disease Janaki Medical College Journal of Medical Sciences (2013) Vol. 1 (2): 3-10 DOI: http://dx.doi.org/10.3126/jmcjms.v1i2.9261

High Risk Populations

Sexually transmitted infections (STIs) other than HIV have reappeared as an important public health problem in developed countries (1). In the late 1970s and early 1980s, research and treatment of the 'classic' STIs - gonorrhea, syphilis and chlamydia - were a major focus of infectious diseases practice and research. There were large outbreaks of syphilis in parts of Canada (2), penicillin-resistantNeisseria gonorrhoeaewas a concern (3), and high rates ofChlamydia trachomatisinfection with complications of pelvic inflammatory disease and ectopic pregnancy were being reported (4,5). Then, HIV infection emerged, with its spectre of a wasting, early death. There was no effective treatment, and safe sexual practices were embraced and adhered to by high-risk populations as the only effective way to avoid infection. These practices effectively prevented other STIs; rates of syphilis, gonorrhea and chlamydia infection plummeted in developed countries (5). For at least a decade, it appeared that HIV might be an end to all STIs, at least for some parts of the world. STIs continued unabated in developing countries, as many epidemiological and therapeutic studies explored the association of STIs with HIV infection.

The Impact

In healthy women, the cervicovaginal microbiota is mostly populated by Lactobacillus spp., the main host defense factor of the female genital tract. In addition to Lactobacilli, other microorganisms populate the cervicovaginal microbiota, like Candida spp. and Gardnerella vaginalis. The overgrowth of Candida spp. or G. vaginalis, known as biofilm-producing microorganisms in the genital ecosystem, may lead to microbial dysbiosis that increases the risk of acquiring sexually transmitted infections, like Chlamydia trachomatis. C. trachomatis, the leading cause of bacterial sexually transmitted diseases, is still considered an important public health problem worldwide because of the impact of asymptomatic infections on long-term reproductive sequelae, including pelvic inflammatory disease and infertility. The aim of our study was to investigate the interaction between C. trachomatis and the biofilm produced by Candida albicans or Gardnerella vaginalis, evaluating whether the biofilm can harbor C. trachomatis and influence its survival as well as its infectious properties. In order to do so, we developed an in vitro coculture transwell-based biofilm model. Our findings proved, for the first time, that C. trachomatis, an intracellular obligate pathogen, survived, for up to 72 hours after exposure, inside the biofilm produced by C. albicans or G. vaginalis, retaining its infectious properties, as evidenced by the typical chlamydial inclusions observed in the cell monolayer (chlamydial inclusion-forming units at 72 h: 9255 ± 1139 and 9873 ± 1015, respectively). In conclusion, our results suggest that the biofilm related to Candida or Gardnerella genital infections may act as a reservoir of C. trachomatis and, thus, contribute to the transmission of the infection in the population as well as to its dissemination into the upper genital tract, increasing the risk of developing severe reproductive sequelae.

Introduction. Nongonococcal urethritis is the most common sexually transmitted infection in men, with vast majority of the etiological agents such as Chlamydia trachomatis, followed by urogenital mycoplasmas. The aim of this study was to determine the prevalence of Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma hominis in nongonococcal urethritis in men, and to examine infections associated with these agents. Material and methods. 299 sexually active, heterosexual men with nongonococcal urethritis were included into the study. Urethral samples were taken with a dacron swab placed into the urethra up to 2-3 cm. The Direct immunojluorescence tehnique was performed for identification of Chlamydia trachomatis. Ureaplasma urealyticum and Mycoplasma hominis were detected with Mycoplasma 1ST assay. Results. Chlamydia trachomatis was detected in 22.75%, Uraeplasma urealyticum in 21.08% and Mycoplasma hominis in 8.02% cases. We found no significant differences in prevalence between Chlamydia trachomatis and Ureaplasma urealyticym (p>0.05). Monoinjections were found in 51.85% with significantly higher rate (p<0.01) than associated infections (11.70%). Among associated infections, coinfection of Chlamydia trahomatis and Ureaplasma urealyticum was predominant. Association of Chlamydia trachomatis with urogenital mycoplasmas was significantly higher (p<0.05) than the one between Ureaplasma urealyticum and Mycoplasma hominis. In 36.45% patients no patogenic microorganisms were detected. Conclusion. These results confirmed the etiological role of Chlamydia trachomatis and urogenital mycoplasmas in nongonococcal urethritis with prevalence of 51.85% in monoinfections and 11.70% in associated infections. In 36.45% of cases the etiology of urethritis was not elucidated. These results suggest that more sensitive diagnostic tool should be applied when searching for the detailed etiology of nongonococcal urethritis.

Actual Prevalence

Chlamydia trachomatis infection is the most common sexually transmitted bacterial infection among women. In Brazil, there is no organized screening program for C. trachomatis, and the actual prevalence of infection is unknown. This study aimed to determine the prevalence of C. trachomatis infection in women living in riverside communities in the Amazon, using self-collection employing the Evalyn® Brush and polymerase chain reaction. A total of 299 riverine women aged 18–81 years, mean age 35.7 (±12.8) years, predominantly agricultural workers, with low schooling and living with a partner, participated in this study. The prevalence of C. trachomatis infection was found to be 3.7% (95% CI 1.8–6.5), most of them being symptomatic. The mean age of the first sexual intercourse reported by women was 15.2 (±2.3) years, and the majority reported having had none or only one partner in the last 12 months, with very low adherence to consistent condom use (15.4%). Most women (98.3%) reported having approved using the vaginal self-collecting brush, and only 4.7% reported having difficulty in handling the brush. We consider that a vaginal self-collecting device is adequate for diagnosing C. trachomatis infection in women living in remote, hard-to-reach areas.

Abstract Background Rectal gonorrhea and Chlamydia are common and predict HIV acquisition among men who have sex with men (MSM); however, screening for rectal sexually transmitted infections (STIs) is not routine. Methods In 2017, we recruited sexually-active MSM in the Portland, Oregon metropolitan area through venue-based sampling. Our outcome of interest was self-reported rectal STI screening in the prior 12 months. Stratified by HIV status, we assessed the prevalence and demographic, healthcare, clinical, and behavioral predictors of screening. Results Of 448 participants, 168 (37.5%) reported rectal STI screening. One hundred twenty-seven (35.8%) of 355 HIV-negative men, 41 (58.6%) of 70 HIV-positive men, and none of 23 men who did not know their HIV status reported screening. Among HIV-negative men, having a healthcare provider who offered HIV testing (adjusted prevalence ratio [aPR]=2.09; 95% confidence interval [CI]: 1.43, 3.04), a syphilis diagnosis (aPR=1.32; 95% CI: 1.03, 1.69), use of pre-exposure prophylaxis (aPR=1.57; 95% CI 1.21, 2.04), and condomless anal sex with casual partners in the prior 12 months (aPR=1.74; 95% CI: 1.36, 2.22) independently predicted screening for rectal STI in multivariable analysis. HIV-positive men who reported having a provider who always or often initiates conversations about sex were significantly more likely to report screening compared with men who did not have such a provider (aPR=1.48; 95% CI: 1.06, 2.06). Conclusion Rectal STI screening is not universal in a venue-based sample of sexually-active MSM. Implementing innovative, acceptable, and accessible screening practices and improving provider comfort with talking about sex are paramount to increasing rectal STI screening.

Abstract Chlamydia trachomatis is the most common sexually transmitted bacterial infection in the United States. Within the U.S. military, the age- and race-adjusted chlamydia infection rates among female service members are consistently higher than civilian rates, with a 20% annual acquisition rate among young active-duty women. The sequelae of chlamydia disproportionately impact women in terms of severity and cost. Untreated chlamydia progresses to pelvic inflammatory disease in 40% of cases, and is a leading cause of fallopian tube damage and pelvic adhesive disease resulting in ectopic pregnancy, tubal infertility, and acute and chronic pelvic pain. Tubal infertility is among the leading indications for in vitro fertilization (IVF) nationally and rates among couples undergoing IVF at military treatment centers are double the national average. Collectively, chlamydia infection represents a significant resource burden to the military health care system and, in view of the serious gynecologic health sequelae, a significant threat to the readiness of servicewomen. In this review, we discuss the gynecologic impact of chlamydia infection within the military, the critical gaps for research funding, and opportunities for intervention.

Pelvic inflammatory disease (PID), a serious infection in sexually active women, is one of the reasons for which females seek care in emergency departments and therefore represents an important public health problem. PID is the result of an endocervical infection with different microorganisms, which then ascend to the endometrium and fallopian tubes. Symptoms of PID may be mild and aspecific, making its diagnosis difficult. However, this clinical condition requires effective antibiotic treatment to reduce incidence of complications and late sequelae. We describe here a case of peritonitis as a complication of pelvic inflammatory disease (PID) due to Neisseria gonorrhoeae infection in a 49-year-old woman who presented at the Emergency Department with acute abdominal pain.

Sex With Men

Chlamydia trachomatis is a common agent of sexually transmitted infection, especially in asymptomatic extra-genital sites among men who have sex with men (MSM). This study aims to investigate anatomical site distribution and genotypes of C. trachomatis from asymptomatic MSM in northeast Thailand. Specimens were collected using swabs from anorectal, oropharyngeal, and urethral sites in 346 asymptomatic MSM. C. trachomatis infection was determined by real-time polymerase chain reaction and genotyping was based on sequences of the ompA gene. The results showed that infection by C. trachomatis was most common at the urethral site (29.1%, 101/346) followed by oropharyngeal (17.6%, 61/346) and anorectal site (17.0%, 59/346). In addition, C. trachomatis infection was significantly associated with absence of condom use (odds ratio = 1.909, 95%CI = 1.054–3.457, P = 0.033) at the urethral site. Overall 49.4% (171/346) of individuals were infected in at least one site. Infection at only the anorectum, oropharynx, or urethra was seen in 9.0, 9.3, and 18.5% of participants, respectively. Concurrent infections at anorectum/oropharynx, anorectum/urethra, oropharynx/urethra, and all three sites were 2.0, 4.3, 4.6, and 1.7%, respectively. Genotype D predominated at the anorectal and urethral sites among asymptomatic MSM in northeast Thailand. Concurrent infection in two or three anatomical sites occurred. C. trachomatis screening at all three sites in asymptomatic MSM is important and should be considered for proper treatment and prevention of transmission.
