The diagnosis of nongonococcal urethritis can be confirmed by the presence of a mucopurulent discharge from the penis, a Gram stain of the discharge with more than five white blood cells per oil-immersion field, and no intracellular gram-negative diplococci.2 A positive result on a leukocyte esterase test of first-void urine or a microscopic examination of first-void urine showing 10 or more white blood cells per high-powered field also confirms the diagnosis of urethritis. 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). Clinical experience and published studies indicate that azithromycin is safe and effective during pregnancy (824826). 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. Topical antibiotic therapy alone is inadequate for treating ophthalmia neonatorum caused by chlamydia and is unnecessary when systemic treatment is administered. No clinical trial data are available that demonstrate that treating M. genitalium cervical infection prevents development of PID or endometritis. A combined assay for simultaneous detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) is used. However, presumptive treatment of the neonate is not indicated because the efficacy of such treatment is unknown. * An association between oral erythromycin and azithromycin and infantile hypertrophic pyloric stenosis (IHPS) has been reported among infants aged <6 weeks. Urine-only screening in an STI clinic misses 83% of infections among MSM.11 They should be screened at each anatomic site of sexual exposure, regardless of condom use, at least annually.2 Routine testing for chlamydial infections of the oropharynx is not recommended, but many laboratories will test for gonococcal and chlamydial infections simultaneously.2 If oropharyngeal chlamydia is diagnosed, it should be treated to decrease the risk of transmission.2. Specimens for chlamydial testing should be collected from the nasopharynx. To obtain a complete sexual history, the five Ps (partners, practices, pregnancy attitudes, previous STIs, and protection from STIs) model can be used as outlined in Table 2.2,5, 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.6 Adolescents and adults diagnosed with an STI in the past year, people reporting irregular condom use, and those with multiple partners or with partners belonging to a high-risk group are at increased risk. Men 35 years or younger who have epididymitis are more likely to have C. trachomatis as the etiologic agent than are older men. Given that 3 out of 4 infected women and Testing for chlamydial infection in neonates can be by culture or nonculture techniques. Inequitable access to health insurance and physicians, language barriers, and distrust of medical systems because of discrimination account for some of these disparities, independent of individual sexual behavior.3,4 Other risk factors are reviewed in Table 1.2, Taking a thorough sexual history is important to identify overall risk of infection, as well as anatomic site-specific risk factors. Early-stage Chlamydia trachomatis infections often cause few symptoms. Observational studies have also demonstrated that doxycycline is more efficacious for rectal C. trachomatis infection for men and women than azithromycin (748,811). CDC twenty four seven. trachomatis is treated with erythromycin base or ethylsuccinate at a dosage of 50 mg per kg per day orally, divided into four doses per day for 14 days.2 As with ophthalmic infection, a second course of therapy may be necessary. Educational materials for female partners should include information about the importance of seeking medical evaluation, especially if PID symptoms are present; undertreatment of PID among female partners and missed opportunities for diagnosing other STIs among women are concerning.

Because the efficacy of erythromycin treatment for ophthalmia neonatorum is approximately 80%, a second course of therapy might be required (834,835). The first clinical treatment failures after moxifloxacin were associated specifically with the S83I mutation in the parC gene (954,960). Treating pregnant women usually prevents transmission of C. trachomatis to neonates during birth. All Rights Reserved. Because clinical presentations differ, all infants aged 13 months suspected of having pneumonia, especially those whose mothers have a history of, are at risk for (e.g., aged <25 years and those aged 25 years who have a new sex partner, more than one sex partner, a sex partner with concurrent partners, or a sex partner who has an STI), or suspected of having a chlamydial infection should be tested for C. trachomatis and treated if infected.

Because erythromycin effectiveness in treating pneumonia caused by C. trachomatis is approximately 80%, a second course of therapy might be required [833]. 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). Although evidence is insufficient to recommend routine screening for C. trachomatis among sexually active young men because of certain factors (i.e., feasibility, efficacy, and cost-effectiveness), screening of sexually active young men should be considered in clinical settings with a high prevalence of chlamydia (e.g., adolescent clinics, correctional facilities, or STD specialty clinics) or for populations with a high burden of infection (e.g., MSM) (149,788). Initial C. trachomatis neonatal infection involves the mucous membranes of the eye, oropharynx, urogenital tract, and rectum, although infection might be asymptomatic in these locations. 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. 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. This content is owned by the AAFP. Some women with C. trachomatis infection develop urethritis; symptoms may consist of dysuria without frequency or urgency. Thus, using a POC test will likely be a cost-effective diagnostic strategy for C. trachomatis infection (807). Chlamydial infection in newborns can cause ophthalmia neonatorum. Persons who receive a diagnosis of chlamydia should be tested for HIV, gonorrhea, and syphilis. Infants should be monitored to ensure prompt and age-appropriate treatment if symptoms develop. Characteristic signs of chlamydial pneumonia among infants include a repetitive staccato cough with tachypnea and hyperinflation and bilateral diffuse infiltrates on a chest radiograph. Symptoms. These cookies may also be used for advertising purposes by these third parties. These are discussed separately: 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. Most women with chlamydial infection have minimal or no symptoms, but some develop pelvic inflammatory disease. The correct volume of urine has been added when the fluid level is between the black lines on the urine transport tube label. In women, chlamydial infection of the lower genital tract occurs in the endocervix. Because chlamydia often doesnt cause symptoms, many people who have chlamydia dont know it and unknowingly infect other people. Test Usage Detection of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis in male or female Doxycycline Preferred for the Treatment of Chlamydia.

Treating persons with C. trachomatis prevents adverse reproductive health complications and continued sexual transmission. Azithromycin (Zithromax) 1 g orally in a single dose, Doxycycline (Vibramycin) 100 mg orally twice per day, Erythromycin base 500 mg orally four times per day, Erythromycin ethylsuccinate 800 mg orally four times per day, Levofloxacin (Levaquin) 500 mg once per day. Amoxicillin is recommended for the treatment of chlamydial infection in women who are pregnant. WebChlamydia trachomatis and Neisseria gonorrhoeae are the most common sexually transmitted infections (STIs) in the United States and are required to be reported to state Use the APTIMA Urine Specimen Collection Kit. Doxycycline is contraindicated during the second and third trimesters of pregnancy because of risk for tooth discoloration. Treatment should be provided promptly for all persons with chlamydial infection; treatment delays have been associated with complications (e.g., PID) in a limited proportion of women (810). WebObjective: The aim of this study was to investigate the relationships between treatment outcomes of patients with urogenital Chlamydia trachomatis infections and minimum inhibitory concentrations (MICs) and drug resistance genes. pain in the lower abdomen. MSM with chlamydia have a high risk for coexisting infections, especially undiagnosed HIV, among their partners and might have partners without HIV who could benefit from HIV PrEP. Sexually active men who have sex with men should be screened at least annually. A negative result does not exclude the possibility of infection. Untreated chlamydia infections can lead to serious health issues including pelvic inflammatory disease (PID) and infertility. Currently, the first-choice treatment for anogenital chlamydia consists of a single 1000 mg dose of azithromycin, or 100 mg doxycycline twice daily for 7 days [ 3, 4 ]. OR Erythromycin is no longer recommended because of the frequency of gastrointestinal side effects that can result in therapy nonadherence. WebInitial C. trachomatisneonatal infection involves the mucous membranes of the eye, oropharynx, urogenital tract, and rectum, although infection might be asymptomatic in If symptomatic treatment failure or a positive test of cure occurs after this regimen, expert consultation is recommended. WebVaginal swab collection: Care provider specimen: Collect vaginal fluid sample using the Gen-Probe Aptima Vaginal Swab Kit by contacting the swab to the lower third of the vaginal wall, rotating the swab for 10 to 30 seconds to absorb the fluid. Levofloxacin is an effective treatment alternative but is more expensive. Test should be performed on a first catch random urine specimen. Copyright 2023 American Academy of Family Physicians. Available evidence supports that doxycycline is efficacious for C. trachomatis infections of urogenital, rectal, and oropharyngeal sites. Although the clinical significance of oropharyngeal C. trachomatis infection is unclear and routine oropharyngeal screening is not recommended, oropharyngeal C. trachomatis can be sexually transmitted to genital sites (211,814); therefore, if C. trachomatis is identified from an oropharyngeal specimen while screening for pharyngeal gonorrhea, it should be treated. Recent studies evaluating the lower and upper genital tract using highly sensitive M. genitalium NAAT assays or the role of M. genitalium in histologically defined endometritis have reported significantly elevated risk for PID (928). Healthcare providers and health departments can report Mgen treatment failures through the Mycoplasma genitalium Treatment Failure Registry. Physicians should emphasize barrier protection as the best way to prevent STIs.2, The USPSTF and Centers for Disease Control and Prevention (CDC) recommend annual screening for chlamydial and gonococcal infections to prevent infertility and pelvic inflammatory disease in sexually active people 24 years and younger with a cervix and in older people with a cervix who have risk factors.2,7 The CDC also recommends at least annual screening for MSM based on their risk factors. 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. Ocular specimens from neonates being evaluated for chlamydial conjunctivitis also should be tested for N. gonorrhoeae (see Ophthalmia Neonatorum Caused by N. gonorrhoeae). Although the majority of M. genitalium strains are sensitive to moxifloxacin, resistance has been reported, and adverse side effects and cost should be considered with this regimen. If testing the partner is not possible, the antimicrobial regimen that was provided to the patient can be provided. Azithromycin (Zithromax) or doxycycline (Vibramycin) is recommended for the treatment of uncomplicated genitourinary chlamydial infection. Which specimen types are suitable for C trachomatis and N gonorrhoeae nucleic acid amplification tests (NAATs)? Data are limited regarding use of minocycline in instances of treatment failure (966). In men, the infection usually is symptomatic, with dysuria and a discharge from the pain in the testicles. Even when symptoms occur, they're often mild. Chlamydia trachomatis is a gram-negative bacterium that infects the columnar epithelium of the cervix, urethra, and rectum, as well as nongenital sites. 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. Women with recurrent cervicitis should be tested for M. genitalium, and testing should be considered among women with PID. Inadequately treated rectal C. trachomatis infection among women who have urogenital chlamydia can increase the risk for transmission and place women at risk for repeat urogenital C. trachomatis infection through autoinoculation from the anorectal site (816). Resistance-guided therapy has demonstrated cure rates of >90% and should be used whenever possible (759,963); however, it requires access to macrolide-resistance testing. All sexually active people with a cervix who are younger than 25 years and older people with a cervix who have risk factors should be screened annually for chlamydial and gonococcal infections. Prevalence of molecular markers for macrolide resistance, which highly correlates with treatment failure, ranges from 44% to 90% in the United States, Canada, Western Europe, and Australia (697,702,945953). Rectal and oropharyngeal C. trachomatis infection among persons engaging in receptive anal or oral intercourse can be diagnosed by testing at the anatomic exposure site. Chlamydia trachomatis is part of the chlamydophila genus. 1. WebChlamydia trachomatis and Neisseria gonorrhoeae RNA, Urine Test Overview Test Methodology Transcription mediated amplification (TMA). WebC trachomatis can be transmitted from the mother during delivery and is associated with conjunctivitis and pneumonia in the newborn. Chlamydial diseases are sexually transmitted and caused by the bacterium Chlamydia trachomatis. However, this bacterium acts more like a virus. This can affect the way chlamydia infection is transmitted and the risk factors that are important in acquiring it. Chlamydia infections can affect the vagina, cervix, and rectum, among other areas. 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).
