Infections caused by Chlamydia trachomatis and Neisseria gonorrhoeae are increasing in the United States. Because chlamydia often doesnt cause symptoms, many people who have chlamydia dont know it and unknowingly infect other people. If health department partner management strategies (e.g., disease intervention specialists) are impractical or unavailable for persons with chlamydia, and if a provider is concerned that sex partners are unable to promptly access evaluation and treatment services, EPT should be considered as permitted by law (see Partner Services). Recommended PID treatment regimens are not effective against M. genitalium. Sexually active people 24 years and younger who have a cervix should be screened for chlamydial and gonococcal infections annually. The existing evidence between M. genitalium and cervicitis is mostly supportive of a causal association. If M. genitalium is detected, a regimen of moxifloxacin 400 mg orally once daily for 14 days has been effective in eradicating the organism. To minimize disease transmission to sex partners, persons treated for chlamydia should be instructed to abstain from sexual intercourse for 7 days after single-dose therapy or until completion of a 7-day regimen and resolution of symptoms if present. Treating persons with C. trachomatis prevents adverse reproductive health complications and continued sexual transmission. A high prevalence of C. trachomatis infection has been observed among women and men who were treated for chlamydial infection during the preceding months (753,755,820822). A combined assay for simultaneous detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) is used.

Detection of Chlamydia trachomatis and Neisseria gonorrhoeae in male or female urine specimens. Hospitalization is required if a patient is pregnant; has severe illness, nausea and vomiting, or high fever; has tuboovarian abscess; is unable to follow or tolerate the outpatient oral regimen; or has disease that has been unresponsive to oral therapy. WebChlamydia trachomatis has been identified as a causative agent for acute urethral syndrome, defined as acute dysuria and frequent urination in women whose voided urine Centers for Disease Control and Prevention.

Doxycycline is contraindicated during the second and third trimesters of pregnancy because of risk for tooth discoloration. Even when symptoms occur, they're often mild. This test is not useful for the detection of other Chlamydia species. [] was to investigate the mutations retrieved in the 23S rRNA gene and their impact on the resistance in C. trachomatis clinical isolates and wild type Thus, using a POC test will likely be a cost-effective diagnostic strategy for C. trachomatis infection (807). Question 2. In men, the infection usually is symptomatic, with dysuria and a discharge from the penis. A rare complication of untreated chlamydial infection is the development of Reiter syndrome, a reactive arthritis that includes the triad of urethritis (sometimes cervicitis in women), conjunctivitis, and painless mucocutaneous lesions. Testing for chlamydial infection in neonates can be by culture or nonculture techniques. Available evidence supports that doxycycline is efficacious for C. trachomatis infections of urogenital, rectal, and oropharyngeal sites. The first clinical treatment failures after moxifloxacin were associated specifically with the S83I mutation in the parC gene (954,960). Recommended Regimens for Chlamydial Infection Among Adolescents and Adults, Recommended Regimen for Chlamydial Infection During Pregnancy, Recommended Regimen for Chlamydial Infection Among Neonates, Recommended Regimen for Chlamydial Pneumonia Among Infants, Recommended Regimens for Chlamydial Infection Among Infants and Children, Centers for Disease Control and Prevention. WebC trachomatis can be transmitted from the mother during delivery and is associated with conjunctivitis and pneumonia in the newborn.

To avoid reinfection, sex partners should be instructed to abstain from condomless sexual intercourse until they and their sex partners have been treated (i.e., after completion of a 7-day regimen) and any symptoms have resolved. Chlamydial infection is the most frequently reported bacterial infectious disease in the United States, and prevalence is highest among persons aged 24 years (141,784). Azithromycin (Zithromax) or doxycycline (Vibramycin) is recommended for the treatment of uncomplicated genitourinary chlamydial infection. Etiology, transmission and protection: Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infection (STI) globally. Although data regarding NAATs for specimens from extragenital sites for children are more limited and performance is test dependent (553), no evidence supports that NAAT performance for detecting C. trachomatis for extragenital sites among children would differ from that among adults. These tests have good sensitivity (85 percent) and specificity (94 to 99.5 percent) for endocervical and urethral samples when compared with urethral cultures.4 In women with urogenital disease, nucleic acid amplification tests can be used with an endocervical sample or a urine specimen to diagnose chlamydia. Nonsexually transmitted pathogens and even non-infectious processes can also cause urogenital, pharyngeal, and rectal symptoms similar to N. gonorrhoeae. We take your privacy seriously. Because most infections are asymptomatic, screening is key to preventing complications such as pelvic inflammatory disease and infertility and decreasing community and vertical neonatal transmission. That makes them easy to Evidence is limited regarding the efficacy of antimicrobial regimens for oropharyngeal chlamydia; however, a recently published observational study indicates doxycycline might be more efficacious than azithromycin for oropharyngeal chlamydia (815). Data regarding the efficacy of azithromycin for ophthalmia neonatorum are limited. M. genitalium is identified in the cervix or endometrium of women with PID more often than in women without PID (918924). Sex partners should be referred for evaluation, testing, and presumptive treatment if they had sexual contact with the partner during the 60 days preceding the patients onset of symptoms or chlamydia diagnosis. Conclusion: Most RNA- or DNA-positive results after treatment of urogenital C. trachomatis may be caused by non-viable molecular remnants since they cannot be confirmed by culture. Follow-up of patients with urethritis is necessary only if symptoms persist or recur after completion of the antibiotic course. Although C. trachomatis has been the most frequent identifiable infectious cause of ophthalmia neonatorum, neonatal chlamydial infections, including ophthalmia and pneumonia, have occurred less frequently since institution of widespread prenatal screening and treatment of pregnant women. 2. Because of the high prevalence of macrolide resistance and high likelihood of treatment failure, this regimen should be used only when a test of cure is possible, and no other alternatives exist. WebChlamydia trachomatis and Neisseria gonorrhoeae RNA, Urine Test Overview Test Methodology Transcription mediated amplification (TMA). Men and women who have been treated for chlamydia should be retested approximately 3 months after treatment, regardless of whether they believe their sex partners were treated; scheduling the follow-up visit at the time of treatment is encouraged (753). Prophylaxis with silver nitrate or antimicrobial ointment, which reduces the risk of gonococcal infection in neonates, does not reduce the risk of chlamydial infection. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. M. genitalium infections among women are also frequently asymptomatic, and the consequences associated with asymptomatic M. genitalium infection are unknown. DFA is the only nonculture FDA-cleared test for detecting C. trachomatis from nasopharyngeal specimens; however, DFA of nasopharyngeal specimens has a lower sensitivity and specificity than culture. WebInitial C. trachomatisneonatal infection involves the mucous membranes of the eye, oropharynx, urogenital tract, and rectum, although infection might be asymptomatic in C. trachomatis infection of neonates results from perinatal exposure to the mothers infected cervix. In a minority viable C. trachomatis was found in culture at the second visit, indicating that patients may remain infectious at least 7 days after treatment. These cookies may also be used for advertising purposes by these third parties. Clinically relevant quinolone resistance often is associated with coexistent macrolide resistance (954). Test of cure (i.e., repeat testing after completion of therapy) to document chlamydial eradication, preferably by NAAT, at approximately 4 weeks after therapy completion during pregnancy is recommended because severe sequelae can occur among mothers and neonates if the infection persists. Although the exposure intervals defining identification of sex partners at risk are based on limited data, the most recent sex partner should be evaluated and treated, even if the time of the last sexual contact was >60 days before symptom onset or diagnosis. Among women, the primary focus of chlamydia screening should be to detect and treat chlamydia, prevent complications, and test and treat their partners, whereas targeted chlamydia screening for men should be considered only when resources permit, prevalence is high, and such screening does not hinder chlamydia screening efforts for women (789791). As part of this approach, doxycycline is provided as initial empiric therapy, which reduces the organism load and facilitates organism clearance, followed by macrolide-sensitive M. genitalium infections treated with high-dose azithromycin; macrolide-resistant infections are treated with moxifloxacin (964,965). POC tests for C. trachomatis among asymptomatic persons can expedite treatment of infected persons and their sex partners. Culture techniques are the preferred method for detecting C. trachomatis infection, but they have been replaced in some instances by nonculture techniques. See permissionsforcopyrightquestions and/or permission requests. Because of the high rates of macrolide resistance with treatment failures (707) and efficient selection of additional resistance, a 1-g dose of azithromycin should not be used. However, C. trachomatis also causes trachoma in endemic areas, mostly Africa and the Middle East, and is a leading cause of preventable blindness worldwide. Testing for cure is indicated in patients who are pregnant and should be performed three weeks after completion of treatment.2 Culture is the preferred technique.2 If risk of reexposure is high, screening should be repeated throughout the pregnancy. Store and transport at room temperature or refrigerated. Adequate specimen collection is important. Among symptomatic patients, POC tests for C. trachomatis can optimize treatment by limiting unnecessary presumptive treatment at the time of clinical decision-making and improve antimicrobial stewardship. M. genitalium causes symptomatic and asymptomatic urethritis among men and is the etiology of approximately 15%20% of NGU, 20%25% of nonchlamydial NGU, and 40% of persistent or recurrent urethritis (697,909,910). 2023 MLABS A Division of Pathology, Michigan Medicine, Chlamydia trachomatis and Neisseria gonorrhoeae RNA, Urine, http://www.pathology.med.umich.edu/handbook/Tables/Aptima_Urine.pdf. Patients usually have unilateral testicular pain with scrotal erythema, tenderness, or swelling over the epididymis. Untreated chlamydial infection can spread to the epididymis. Testing should be accompanied with resistance testing, if available. Annual screening for rectal C. trachomatis infection should be performed among men who report sexual activity at the rectal site. Similarly, evidence for a role for M. genitalium infection during pregnancy as a cause of perinatal complications, including preterm delivery, spontaneous abortion, or low birthweight, are conflicting because evidence is insufficient to attribute cause (766,932934). Exposure to C. trachomatis during delivery can cause ophthalmia neonatorum (conjunctivitis) in neonates or chlamydial pneumonia at one to three months of age. The CDC recommends that anyone who is tested for chlamydial infection also should be tested for gonorrhea.2 This recommendation was supported by a study5 in which 20 percent of men and 42 percent of women with gonorrhea also were found to be infected with C. trachomatis. They help us to know which pages are the most and least popular and see how visitors move around the site. Nonpregnant people treated for chlamydial or gonococcal infections should be tested for reinfection three months after treatment. Although azithromycin maintains high efficacy for urogenital C. trachomatis infection among women, concern exists regarding effectiveness of azithromycin for concomitant rectal C. trachomatis infection, which can occur commonly among women and cannot be predicted by reported sexual activity. Self-collected rectal swabs are a reasonable alternative to clinician-collected rectal swabs for C. trachomatis screening by NAAT, especially when clinicians are not available or when self-collection is preferred over clinician collection. Between 2015 and 2019, reported chlamydial infections increased by 19%, and reported gonococcal infections increased by 53%.1 These bacteria commonly infect the urogenital, anorectal, and pharyngeal sites but can become disseminated to affect multiple organ systems. NAATs can be used to test vaginal and urine specimens from girls and urine in boys (see Sexual Assault or Abuse of Children).

Patient collection of a meatal swab for C. trachomatis testing might be a reasonable approach for men who are either unable to provide urine or prefer to collect their own meatal swab over providing urine. 2022 Mar 2;75:103448. doi: These are discussed separately: The association with PID is supported by early studies among nonhuman primates that determined that endosalpingitis develops after inoculation with M. genitalium (927). Levofloxacin is an effective treatment alternative but is more expensive. Treating pregnant women usually prevents transmission of C. trachomatis to neonates during birth. Re-cap the urine specimen transport tube tightly and label with two identifiers. Among women, M. genitalium has been associated with cervicitis, PID, preterm delivery, spontaneous abortion, and infertility, with an approximately twofold increase in the risk for these outcomes among women infected with M. genitalium (766). If symptomatic treatment failure or a positive test of cure occurs after this regimen, expert consultation is recommended. Individual CT and NG test options are not available.

All information these cookies collect is aggregated and therefore anonymous. The most common bacterial sexually transmitted disease (STD) in the U.S., chlamydia is usually spread through vaginal, anal, and oral sex. The few prospective studies that have evaluated the role of M. genitalium in establishing subsequent PID demonstrated increased PID risk; however, these were not statistically significant associations, often because of a lack of statistical power. WebC trachomatis can be transmitted from the mother during delivery and is associated with conjunctivitis and pneumonia in the newborn. Chlamydia trachomatis-Neisseria gonorrhoeae RNA, Urine. The majority of persons with C. trachomatis detected at oropharyngeal sites do not have oropharyngeal symptoms. In clinical practice, if testing is unavailable, M. genitalium should be suspected in cases of persistent or recurrent urethritis or cervicitis and considered for PID. In women, chlamydial infection of the lower genital tract occurs in the endocervix. Patient information: See related handouts on chlamydia, written by the authors of this article, and on gonorrhea, which has been adapted from a previously published AFP article. MSM who are HIV negative with a rectal chlamydia diagnosis should be offered HIV PrEP. Nucleic acids may persist for up to 4 weeks following appropriate antimicrobial therapy.

A randomized trial for the treatment of rectal chlamydia infection among MSM reported microbiologic cure was 100% with doxycycline and 74% with azithromycin (812). The eyelid should be everted and the sample obtained from the inner aspect of the eyelid. The possibility of concomitant chlamydial pneumonia should be considered (see Infant Pneumonia Caused by C. trachomatis). trachomatis (37 samples; 5.9% using TMA assays) and the anatomical site with the highest prevalence of microorganisms was a non-urogenital site, the pharynx (27 positive samples; 4.3%). The patient should not have urinated for at least 1 hour prior to sample collection. Use the APTIMA Urine Specimen Collection Kit. Compared with standard patient referral of partners, this approach to therapy, which involves delivering the medication itself or a prescription by the patient or collaborating pharmacy, has been associated with decreased rates of persistent or recurrent chlamydia among women (125127). Sex partners of patients with symptomatic M. genitalium infection can be tested, and those with a positive test can be treated to possibly reduce the risk for reinfection. Chlamydia trachomatis infection most commonly affects the urogenital tract. Which specimen types are suitable for C trachomatis and N gonorrhoeae nucleic acid amplification tests (NAATs)? The U.S. Preventive Services Task Force (USPSTF) recommends behavioral counseling on condom use, communication strategies for safer sex, and problem solving with those at increased risk of STIs. Women can develop reactive arthritis, but the male-to-female ratio is 5:1. You can get chlamydia from intercourse, anal sex or oral sex. Web2021 STI Treatment Guidelines Chlamydial Infections Includes updated treatment and screening recommendations, as well as information on diagnosis, prevention, and special considerations. Mothers of infants who have chlamydial pneumonia and the sex partners of these women should be evaluated, tested, and presumptively treated for chlamydia (see, Chlamydial Infection Among Adolescents and Adults). See permissionsforcopyrightquestions and/or permission requests. Ophthalmia neonatorum usually occurs within five to 12 days of birth but can develop at any time up to one month of age.2 It may cause swelling in one or both eyes with mucopurulent drainage.

Methods: The clinical data of 92 patients diagnosed with Chlamydia trachomatis (C. trachomatis) infections were Sampling the exudates is not adequate because this technique increases the risk of a false-negative test. If symptoms suggest recurrent or persistent urethritis, the CDC recommends treatment with 2 g metronidazole (Flagyl) orally in a single dose plus 500 mg erythromycin base orally four times per day for seven days, or 800 mg erythromycin ethylsuccinate orally four times per day for seven days.2 [ corrected] This recommendation is to provide treatment for other bacterial causes of urethritis. For men, C. trachomatis urethral infection can be diagnosed by testing first-void urine or a urethral swab. Optimal urogenital specimen types for chlamydia screening by using NAAT include first-catch urine (for men) and vaginal swabs (for women) (553).

Because the efficacy of erythromycin treatment for ophthalmia neonatorum is approximately 80%, a second course of therapy might be required (834,835). Physicians should obtain a sexual history free from assumptions about sex partners or practices. WebChlamydia is caused by the obligate intracellular bacterium Chlamydia trachomatis and is the most prevalent sexually transmitted infection (STI) caused by bacteria in the United States.In 2020, over 1.5 million documented cases were reported to the C e n te r s f o r Di s e a s e C on t ro l a n d P r e v e n ti o n (CDC). For uncomplicated genitourinary chlamydial infection, the CDC recommends 1 g azithromycin (Zithromax) orally in a single dose, or 100 mg doxycycline (Vibramycin) orally twice per day for seven days (Table 1).2 These regimens have similar cure rates and adverse effect profiles,6 although a benefit of azithromycin is that physicians can administer the dose in the office. Chlamydial pneumonia can occur at one to three months of age, manifesting as a protracted onset of staccato cough, usually without wheezing or fever. Test of cure is not recommended for asymptomatic persons who received treatment with a recommended regimen. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Urinalysis usually will show more than five white blood cells per high-powered field, but urethral cultures generally are negative. NICOLE YONKE, MD, MPH, MIRANDA ARAGN, MD, AND JENNIFER K. PHILLIPS, MD, Related Letter to the Editor:Doxycycline Preferred for the Treatment of Chlamydia. In men, chlamydial infection of the lower genital tract causes urethritis and, on occasion, epididymitis. All newborns should receive ocular erythromycin 0.5% ointment to prevent gonococcal ophthalmia neonatorum. A more recent article on chlamydial and gonococcal infections is available. Similarly, although asymptomatic M. genitalium has been detected in the pharynx, no evidence exists of it causing oropharyngeal symptoms or systemic disease. Recent studies report a high concordance of M. genitalium among partners of males, females, and MSM; however, no studies have determined whether reinfection is reduced with partner treatment (940,967,968). Rectal infections often are asymptomatic, although higher prevalence of M. genitalium has been reported among men with rectal symptoms. Data are limited regarding use of minocycline in instances of treatment failure (966). Data from case-control serologic studies (929931) and a meta-analysis of clinical studies (766) indicate a potential role in causing infertility. As an alternative, prevention efforts should focus on prenatal screening for C. trachomatis, including. If testing the partner is not possible, the antimicrobial regimen that was provided to the patient can be provided. Extragenital chlamydial testing at the rectal site can be considered for females on the basis of reported sexual behaviors and exposure through shared clinical decision-making by the patient and the provider.

Erythromycin base or ethylsuccinate 50 mg/kg body weight/day orally, divided into 4 doses daily for 14 days*. Men with recurrent NGU should be tested for M. genitalium using an FDA-cleared NAAT. The correct volume of urine has been added when the fluid level is between the black lines on the urine transport tube label. Infections in the rectum may cause problems or This assay should not be used for the evaluation of suspected sexual abuse or other medico-legal investigations where chain of custody is required. Sexually active adolescents and adults at increased risk of acquiring a sexually transmitted infection should receive behavioral counseling to reduce their risk. Untreated infections may lead to pelvic inflammatory disease; scarring of fallopian tubes, which can increase the risk of ectopic pregnancy; infertility; easier transmission of new HIV infection; and vertical neonatal transmission.2, Young people 15 to 24 years of age account for 61% of all newly diagnosed STIs.1 Racial and ethnic minorities, men who have sex with men (MSM), and transgender and gender diverse people are at higher risk of STIs.
