2015 European guideline on the management of Chlamydia trachomatis infections.

Chlamydia trachomatis infections, which most frequently are asymptomatic, are major public health concerns globally. The 2015 European C. trachomatis guideline provides: up-to-date guidance regarding broader indications for testing and treatment of C. trachomatis infections; a clearer recommendation of using exclusively-validated nucleic acid amplification tests for diagnosis; advice on (repeated) C. trachomatis testing; the recommendation of increased testing to reduce the incidence of pelvic inflammatory disease and prevent exposure to infection; and recommendations to identify, verify and r…

Dysuria in the emergency department: missed diagnosis of Chlamydia trachomatis.

INTRODUCTION: The clinical presentation of genital Chlamydia trachomatis infection (chlamydia) in women is often indistinguishable from a urinary tract infection. While merited in the setting of dysuria, emergency department (ED) clinicians do not routinely test for chlamydia in women. The primary aim of our study was to evaluate the frequency of chlamydia testing among women presenting to the ED with dysuria. METHODS: We conducted a retrospective chart review of women 19-25 years of age presenting with dysuria to an urban ED and who had been coded with urinary tract infection (UTI) as their …

[Occurrence of Chlamydia trachomatis infections in infertile women in Poland].

INTRODUCTION: Chiamydia trachomatis represents a causal factor of sexually transmitted infections (STI), the course of which is frequently asymptomatic. Chronic and relapsing infections with Chlamydia trachomatis may result in a disturbed function of oviducts, resulting in infertility. OBJECTIVES: The aim of the study was to evaluate the relationship between manifestations of asymptomatic infections with Chlamydia trachomatis and infertility among Polish women. MATERIAL AND METHODS: The study was conducted between 2010-2013 on 543 women in two groups. Group 1 included 190 patients (aged 23-3…

Chlamydia trachomatis conjunctivitis in a male teenager: a case report.

An 18 year old man was seen at a Sexually Transmitted Infections (STIs) clinic for counselling and treatment of Chlamydia trachomatis genital infection which had been diagnosed during a screening survey of high school students. For two months he had reported conjunctival hyperaemia, increased tearing, itching, and mucopurulent secretions, predominantly on the left eye. His ophthalmologist had made a diagnosis of follicular conjunctivitis and lower superficial punctate keratitis (left eye more than right eye), irresponsive to topical treatment. Chlamydial conjunctivitis was suspected and confir…

Есть ли доказательства нового варианта хламидиотрахоматиса в США?

Для обнаружения шведского варианта (nvCT) штамма хламидии трахоматиса (CT) была разработана специальная цепная реакция в режиме реального времени с последующим анализом кривой плавления. Было проведено наблюдение за 476 КТ-позитивными клиническими образцами, полученными в 15 лабораториях по всей территории Соединенных Штатов, с использованием тестов на усиление нуклеиновой кислоты, которые не будут пропущены в NvCT. Все они были отрицательными для nvCT; таким образом, нет никаких доказательств существования nvCT в Соединенных Штатах.

Chlamydia trachomatis infection of the male genital tract: an update.

Chlamydia trachomatis (CT) is the most prevalent cause of sexually transmitted diseases. Although the prevalence of chlamydial infection is similar in men and women, current research and screening are still focused on women, who develop the most severe complications, leaving the study of male genital tract (MGT) infection underrated. Herein, we reviewed the literature on genital CT infection with special focus on the MGT. Data indicate that CT certainly infects different parts of the MGT such as the urethra, seminal vesicles, prostate, epididymis and testis. However, whether or not CT infectio…

An assessment of the current Chlamydia trachomatis laboratory practices in Germany.

BACKGROUND AND OBJECTIVES: Currently, no information is available about the number of Chlamydia trachomatis (CT) tests performed, testing facilities available or diagnostic methods used in Germany. This study aimed to map CT diagnostic facilities so that representative laboratories can be recruited for CT sentinel surveillance. METHODS: Using a questionnaire, we collected information about population coverage, the number of tests performed, accreditation and current testing methods and systems for German facilities that potentially offer CT diagnostics. RESULTS: Overall, 725/1,504 (48%) faci…

[Classical and molecular methods for diagnosis of Chlamydia trachomatis infections].

INTRODUCTION: Genital Chlamydia trachomatis infection is the leading cause of bacterial sexually transmitted diseases in industrial countries, particularly among young people. The consequences of chlamydial infections may involve pelvic inflammatory disease, ectopic pregnancy and tubal factor infertility. METHODS: Available tests for detection of chlamydia in men and women include culture in tissue culture cells, direct immunofluorescence test, enzyme immune assay, nucelic acid probe hibridization and polymerase chain reaction. Nucleic acid amplification tests use different ribonucleic and de…

[Chlamydia trachomatis and urogenital mycoplasms in nonconococcal urethritis in men].

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 …

Chlamydia trachomatis serology in women with and without ovarian cancer.

Pelvic inflammation has been implicated in the genesis of ovarian cancer. We conducted serologic measurements of Chlamydia trachomatis antibodies as a surrogate marker of chlamydial pelvic inflammatory disease. Women with ovarian cancer (n = 521) and population-based controls (n = 766) were tested. IgG antibodies to serovar D of chlamydia elementary bodies (EBs) were detected using an ELISA assay. The odds of having ovarian cancer among women with the highest titers (>or=0.40 OD units) were 0.6 (95% CI 0.4-0.9). These data do not support our earlier finding of elevated titers for antibodies to…

Coverage is the key for effective screening of Chlamydia trachomatis in Australia.

BACKGROUND: The rate of diagnosis of Chlamydia trachomatis (chlamydia) infection has risen dramatically in Australia. In response, the Australian government is planning to implement systematic screening and testing. Several decisions must be made, including whom to screen. METHODS: To inform decisions surrounding screening, a dynamic transmission model of the chlamydia epidemic was developed and parameterized with Australian sexual behavior and epidemiology data. A range of screening strategies and coverage rates were evaluated targeting various groups based on age and sex. Rigorous uncertain…

Prevalence of Chlamydia trachomatis infection in women with cervical lesions.

PURPOSE: The study objective was to evaluate the prevalence of Chlamydia trachomatis (C. trachomatis) infection in women with and without pathological lesions in the uterine cervix. MATERIAL AND METHODS: A total of 120 patients, aged 15-57 (mean age 29), recruited for the study, were referred by gynaecological clinics in the Podlasie province. Gynaecological examinations confirmed cervicitis accompanied by erosions in 75 patients (group I) and cervicitis alone in 45 women (group II). The comparative group (control) consisted of 35 women, aged 16-48 years (mean age 29), who had no clinical sym…

Prevalence of Chlamydia trachomatis in a public colposcopy clinic population.

BACKGROUND: Chlamydia trachomatis is a major public health issue, with notifications of this sexually transmitted disease continuing to rise in Australia. Women attending colposcopy clinics are referred for treatment of cervical abnormalities often associated with human papilloma virus (HPV) infection. There is evidence that women who have acquired one sexually transmitted infection, such as HPV, are at higher risk of acquiring another. Women attending colposcopy clinics may therefore be at risk of undiagnosed infection with C. trachomatis. AIM: To determine the prevalence of C. trachomatis i…

[A young infant with afebrile pneumonia caused by Chlamydia trachomatis].

Pregnant women who have an urogenital Chlamydia trachomatis infection may transmit the infection to their infants. Conjunctivitis and nasopharyngeal infection are the most frequent manifestations. Less frequently the infants may develop pneumonia. We report a case of a 5-week-old girl with poor feeding, staccato cough and clinical signs of pneumonia. Chest radiography revealed severe bronchopneumonia. Despite of intravenous therapy with ampicillin and gentamicin respiration deteriorated and oxygen supplementation became necessary. After additional treatment with oral erythromycin (50 mg/kg per…

[Detection of chlamydia trachomatis in urine, vulval and cervical swabs].

BACKGROUND: Increased testing rates for Chlamydia infection among young women can be achieved by more use of self-administered sampling methods. In this study, vulval swabs and urine are compared to conventional cervix samples. MATERIALS AND METHODS: Vulval swabs, urine and cervix samples from 541 young, healthy women were tested for Chlamydia by polymerase chain reaction technique. RESULTS: The prevalence of Chlamydia infection was 4.1% (22/541). The sensitivity (cervix 22/22, urine 21/22 and vulva 21/22) and specificity (no false negative results) were high for all sampling sites. INTERPR

The prevalence of asymptomatic Chlamydia trachomatis in military dependent adolescents.

Chlamydia trachomatis infection is common among sexually active populations and often asymptomatic. Infection is associated with complications, including pelvic inflammatory disease and infertility. Using a noninvasive urine ligase chain reaction assay, we determined the prevalence of asymptomatic C. trachomatis infection among sexually active military dependent adolescents and young adults attending clinics at military facilities in San Antonio. The overall prevalence rate was 14%, higher than that reported in many high-risk settings, including sexually transmitted disease clinics. Gender-spe…

Chlamydia trachomatis disguised as an asymptomatic scrotal mass in adolescents.

We present two cases of adolescents who presented with painless scrotal masses suggestive of testicular cancer. Diagnostic workup of both these patients revealed Chlamydia trachomatis and both patients were successfully treated with doxycycline. Both patients initially denied sexual activity. We suggest that a high index of suspicion is warranted in adolescent patients that present with asymptomatic scrotal masses and precise tests for C. trachomatis be done to rule out an infectious cause.
