Copyright 2006 by the American Academy of Family Physicians. NAATs that are FDA cleared for use with vaginal swab specimens can be collected by a clinician or patient in a clinical setting. If symptomatic treatment failure or a positive test of cure occurs after this regimen, expert consultation is recommended. Although data regarding use of azithromycin for treating neonatal chlamydial infection are limited, available data demonstrate that a short therapy course might be effective (834). This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. Data are insufficient to implicate M. genitalium infection with chronic complications among men (e.g., epididymitis, prostatitis, or infertility). You will be subject to the destination website's privacy policy when you follow the link. C. trachomatis is the most common infectious Some feminine sprays, powders, spermicidal agents, and lubricants may interfere with the assay and should not be used prior to specimen collection. Prophylaxis with silver nitrate or antimicrobial ointment, which reduces the risk of gonococcal infection in neonates, does not reduce the risk of chlamydial infection. What gender do your partners identify as? All nonpregnant people should be tested for reinfection approximately three months after treatment or at the first visit in the 12 months after treatment. The newest nonculture technique is the nucleic acid amplification test, of which there are several. Individual CT and NG test options are not available. Treatment for Oral Chlamydia. Chlamydia is usually treated with antibiotics like azithromycin which is usually prescribed in a single, large dose, and doxycycline is taken twice per day for about one week. The same antibiotics to treat chlamydia in the groin and may also be prescribed to treat chlamydia in the throat. It is important to avoid Because chlamydia often doesnt cause symptoms, many people who have chlamydia dont know it and unknowingly infect other people. Data regarding the efficacy of azithromycin for ophthalmia neonatorum are limited. 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. Infection with C. trachomatis is common in selected geographic areas (911913), although M. genitalium is often the sole pathogen. Infants should be monitored to ensure prompt and age-appropriate treatment if symptoms develop. 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. Nucleic acids may persist for up to 4 weeks following appropriate antimicrobial therapy. Store and transport at room temperature or refrigerated. Transcription mediated amplification (TMA). Screening of asymptomatic M. genitalium infection among women and men or extragenital testing for M. genitalium is not recommended. The treatment of C. trachomatis infection depends on the site of the infection, the age of the patient, and whether the infection is complicated or uncomplicated. DFA is the only nonculture FDA-cleared test for detecting chlamydia from conjunctival swabs. All Rights Reserved. Infants treated with either of these antimicrobials should be followed for IHPS signs and symptoms. M. genitalium is an extremely slow-growing organism. You can get chlamydia from intercourse, anal sex or oral sex. Erythromycin is no longer recommended because of the frequency of gastrointestinal side effects that can result in therapy nonadherence. Web2021 STI Treatment Guidelines Chlamydial Infections Includes updated treatment and screening recommendations, as well as information on diagnosis, prevention, and special considerations. All information these cookies collect is aggregated and therefore anonymous. Clinical microscopy and the amine test (i.e., significant odor release on addition of potassium hydroxide to vaginal secretions) can be used to help differentiate chlamydial infection from other lower genital tract infections such as urinary tract infection, bacterial vaginosis, and trichomoniasis.3 In addition, chlamydial infection in the lower genital tract does not cause vaginitis; thus, if vaginal findings are present, they usually indicate a different diagnosis or a coinfection. Women with recurrent cervicitis should be tested for M. genitalium, and testing should be considered among women with PID. The purpose of the study performed by Jiang et al. For children weighing 45 kg but aged <8 years: Azithromycin 1 g orally in a single dose, For children aged 8 years: Azithromycin 1 g orally in a single dose. As an alternative, prevention efforts should focus on prenatal screening for C. trachomatis, including. Follow-up of infants is recommended to determine if the pneumonia has resolved, although certain infants with chlamydial pneumonia continue to have abnormal pulmonary function tests later during childhood. Specimens for culture isolation and nonculture tests should be obtained from the everted eyelid by using a Dacron (DuPont)-tipped swab or the swab specified by the manufacturers test kit; for culture and DFA, specimens must contain conjunctival cells, not exudate alone. NAATs can be used to test vaginal and urine specimens from girls and urine in boys (see Sexual Assault or Abuse of Children). NICOLE YONKE, MD, MPH, MIRANDA ARAGN, MD, AND JENNIFER K. PHILLIPS, MD, Related Letter to the Editor:Doxycycline Preferred for the Treatment of Chlamydia. Furthermore, treating their sex partners can prevent reinfection and infection of other partners. WebChlamydia trachomatis Neisseria gonorrhoeae RNA TMA | Quest Diagnostics Chlamydia trachomatis / Neisseria gonorrhoeae RNA, TMA Test code (s) 11363 (X), 11361 (X), To observe the discharge, the penis may need to be milked by applying pressure from the base of the penis to the glans. Chlamydial pneumonia among infants typically occurs at age 13 months and is a subacute pneumonia. Test should be performed on a first catch random urine specimen. When nonadherence to doxycycline regimen is a substantial concern, azithromycin 1 g regimen is an alternative treatment option but might require posttreatment evaluation and testing because it has demonstrated lower treatment efficacy among persons with rectal infection. Erythromycin base or ethylsuccinate 50 mg/kg body weight/day orally divided into 4 doses daily for 14 days, Azithromycin suspension20 mg/kg body weight/day orally, 1 dose daily for 3 days. Urogenital M. genitalium infection is associated with HIV among both men and women (942944); however, the data are from case-control and cross-sectional studies. 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. Human data reveal that levofloxacin presents a low risk to the fetus during pregnancy but has potential for toxicity during breastfeeding; however, data from animal studies increase concerns regarding cartilage damage to neonates (431). Test of cure to detect therapeutic failure (i.e., repeat testing 4 weeks after completing therapy) is not advised for nonpregnant persons treated with the recommended or alternative regimens, unless therapeutic adherence is in question, symptoms persist, or reinfection is suspected. In settings without access to resistance testing and when moxifloxacin cannot be used, an alternative regimen can be considered, based on limited data: doxycycline 100 mg orally 2 times/day for 7 days, followed by azithromycin (1 g orally on day 1 followed by 500 mg once daily for 3 days) and a test of cure 21 days after completion of therapy (963). This is best observed in the morning, before the patient voids. 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. Molecular tests for macrolide (i.e., azithromycin) or quinolone (i.e., moxifloxacin) resistance markers are not commercially available in the United States. 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). All Rights Reserved. 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. This test is not useful for the detection of other Chlamydia species. Hospitalization also is indicated if surgical emergencies cannot be excluded.2 The CDC-recommended options for the treatment of PID are listed in Table 2.2, Doxycycline and ofloxacin (Floxin) are contraindicated during pregnancy; therefore, the CDC recommends erythromycin base or amoxicillin for the treatment of chlamydial infection in pregnant women (Table 3).2 Amoxicillin is more effective and tends to have fewer side effects than erythromycin in the treatment of antenatal chlamydial infection, and thus is better tolerated.7,8 Preliminary data suggest that azithromycin is a safe and effective alternative.2. If macrolide sensitive:Doxycycline 100 mg orally 2 times/day for 7 days, followed by azithromycin 1 g orally initial dose, followed by 500 mg orally once daily for 3 additional days (2.5 g total), If macrolide resistant: Doxycycline 100 mg orally 2 times/day for 7 days followed by moxifloxacin 400 mg orally once daily for 7 days, If M. genitalium is detected by an FDA-cleared NAAT: Doxycycline 100 mg orally 2 times/day for 7 days, followed by moxifloxacin 400 mg orally once daily for 7 days. Chlamydia trachomatis is part of the chlamydophila genus. Similarly, although asymptomatic M. genitalium has been detected in the pharynx, no evidence exists of it causing oropharyngeal symptoms or systemic disease. Data are lacking regarding use of NAATs for specimens from extragenital sites (rectum and pharynx) among boys and girls (553); other nonculture tests (e.g., DFA) are not recommended because of specificity concerns. Patients who are pregnant should be tested for cure three weeks after treatment for chlamydial infection. Erythromycin base or ethylsuccinate 50 mg/kg body weight/day orally, divided into 4 doses daily for 14 days*. Patient-collected vaginal swab specimens are equivalent in sensitivity and specificity to those collected by a clinician using NAATs (792,793), and this screening strategy is highly acceptable among women (794,795). Data are also limited regarding effectiveness of EPT in reducing persistent or recurrent chlamydia among MSM (123,133,134); thus, shared clinical decision-making regarding EPT for MSM is recommended. Use the APTIMA Urine Specimen Collection Kit. Given that 3 out of 4 infected women and A combined assay for simultaneous detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) is used. After discussion with the patient, it may be necessary to screen those sites even without reported exposure because of underreporting of sexual practices.2 Table 3 summarizes screening recommendations for chlamydial and gonococcal infections.2,8 There are significant gaps in research as it pertains to screening transgender and gender diverse patients.9 The CDC recommends screening based on an individuals current anatomy and sexual practices.2, Screening for urogenital infections only and neglecting pharyngeal and rectal sites of exposure will miss a substantial proportion of chlamydial and gonococcal infections.10 In one study of women who engaged in oral or anal sex with men, the prevalence of pharyngeal gonorrhea was 3.5%; rectal gonorrhea, 4.8%; and rectal chlamydia, 11.8%.10 Pharyngeal and rectal screening may be offered to people with female anatomy based on sexual practices and shared decision-making.2 Current evidence for screening extra-genital sites is strongest for MSM. If tracheal aspirates or lung biopsies are being collected for pneumonia in infants one to three months of age, the samples should be tested for C. trachomatis.2. 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. 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. Uncomplicated gonococcal infection should be treated with a single 500-mg dose of intramuscular ceftriaxone in people weighing less than 331 lb (150 kg). The clinical significance of oropharyngeal C. trachomatis infection is unclear, and prevalence is low, even among populations at high risk. Testing for chlamydial infection in neonates can be by culture or nonculture techniques. Author disclosure: No relevant financial relationships. The Centers for Disease Control and Prevention and the U.S. Preventive Services Task Force recommend screening for chlamydial infection in women at increased risk of infection and in all women younger than 25 years. The patient should not have urinated for at least 1 hour prior to sample collection. Immediately place the swab into the transport tube and carefully break the swab shaft against the side of Re-cap the urine specimen transport tube tightly and label with two identifiers. 2022 Mar 2;75:103448. doi: Cookies used to make website functionality more relevant to you. However, C. trachomatis also causes trachoma in endemic areas, mostly Africa and the Middle East, and is a leading cause of preventable blindness worldwide. These materials also should inform partners about potential therapy-related allergies and adverse effects, along with symptoms indicative of complications (e.g., testicular pain among men and pelvic or abdominal pain among women). CDC twenty four seven. 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. Are samples other than genital samples, such as throat and rectal swabs, acceptable for C trachomatis and N gonorrhoeae NAATs? Resistance to azithromycin has been rapidly increasing and has been confirmed in multiple studies. Thank you for taking the time to confirm your preferences. In men, the infection usually is symptomatic, with dysuria and a discharge from the penis. Test Usage Detection of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis in male or female 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. WebChlamydia trachomatis, Nucleic Acid Amplification, Varies Z Useful For Detecting Chlamydia trachomatis This test is not intended for use in medico-legal applications. Repeat infections confer an elevated risk for PID and other complications among women. WebChlamydia trachomatis and Neisseria gonorrhoeae RNA, Urine Test Overview Test Methodology Transcription mediated amplification (TMA). Chlamydia is a treatable infection. Processes should be in place to ensure communication between physicians and others caring for the mother and the newborn to ensure thorough monitoring of the newborn after birth. Chlamydial infection in newborns can cause ophthalmia neonatorum. WebComponents: Chlamydia trachomatis RNA, TMA, Urogenital Chlamydia trachomatis RNA, TMA, Urogenital test cost is between $43.00 and $77.00 None $43.00 Order Ulta Lab Tests Compare - Chlamydia and Gonorrhea Test (EW) Covered tests: Chlamydia/Neisseria gonorrhoeae RNA, TMA, Urogenital ( partial ) ( Quest ) The differential diagnosis of gonococcal infections depends on the particular clinical syndrome. 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. Which specimen types are suitable for C trachomatis and N gonorrhoeae nucleic acid amplification tests (NAATs)? pain. Erythromycin is no longer recommended because of the frequency of gastrointestinal side effects, which can result in nonadherence. Finally, C trachomatis may cause hepatitis Topical antibiotic therapy alone is inadequate for treating ophthalmia neonatorum caused by chlamydia and is unnecessary when systemic treatment is administered. Chlamydia is an infection caused by the Chlamydia trachomatis bacteria. Cookies used to enable you to share pages and content that you find interesting on CDC.gov through third party social networking and other websites. 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). The treatment of urethritis, cervicitis, proctitis, and epididymitis secondary to C. trachomatis infection as well as the POC tests for C. trachomatis among asymptomatic persons can expedite treatment of infected persons and their sex partners. Testing can be performed on a sample obtained from the nasopharynx. Rectal infection with M. genitalium has been reported among 1%26% of MSM (937940) and among 3% of women (941). Therefore, follow-up of infants is recommended to determine whether the initial treatment was effective. M. genitalium can be detected among 10%30% of women with clinical cervicitis (767,770,772,914916). Patients should be advised to abstain from sexual intercourse for seven days after treatment initiation. Women with chlamydial infection should be rescreened for infection three to four months after completion of antibiotic therapy. Test Usage Detection of The majority of posttreatment infections do not result from treatment failure but rather from reinfection caused by failure of sex partners to receive treatment or initiation of sexual activity with a new infected partner (823), indicating a need for improved education and treatment of sex partners. Finally, C trachomatis may cause 1. Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. Previous evidence indicates that the liquid-based cytology specimens collected for Pap smears might be acceptable specimens for NAAT, although test sensitivity using these specimens might be lower than that associated with use of cervical or vaginal swab specimens (799); regardless, certain NAATs have been cleared by FDA for use on liquid-based cytology specimens. These are discussed separately: Healthcare providers and health departments can report Mgen treatment failures through the Mycoplasma genitalium Treatment Failure Registry. The cervix tends to bleed easily when rubbed with a polyester swab or scraped with a spatula. However, most studies of M. genitalium and PID, even those that controlled extensively for other infections and behavioral and biologic risk, are cross-sectional. If retesting at 3 months is not possible, clinicians should retest whenever persons next seek medical care <12 months after initial treatment. 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. Topical treatment is ineffective for ophthalmia neonatorum and should not be used even in conjunction with systemic treatment. 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. Nonculture techniques may be used, but they are less sensitive and specific for nasopharyngeal specimens than for ocular specimens. Exposure to C. trachomatis during delivery can cause ophthalmia neonatorum (conjunctivitis) in neonates or chlamydial pneumonia at one to three months of age. In this case, the main symptoms are often: discharge. Doxycycline Preferred for the Treatment of Chlamydia. A more recent article on chlamydial and gonococcal infections is available. Culture can take up to 6 months, and technical laboratory capacity is limited to research settings. It can cause an odorless, mucoid vaginal discharge, typically with no external pruritus, although many women have minimal or no symptoms.2 An ascending infection can result in pelvic inflammatory disease (PID). NAAT for M. genitalium is FDA cleared for use with urine and urethral, penile meatal, endocervical, and vaginal swab samples (https://www.hologic.com/package-inserts/diagnostic-products/aptima-mycoplasma-genitalium-assay). CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. 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. Because the efficacy of erythromycin treatment for ophthalmia neonatorum is approximately 80%, a second course of therapy might be required (834,835). 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. The first clinical treatment failures after moxifloxacin were associated specifically with the S83I mutation in the parC gene (954,960). In addition, systematic reviews and meta-analyses have noted an association with macrolide antimicrobials, especially erythromycin, during pregnancy and adverse child outcomes, indicating cautious use in pregnancy (830831). How do you protect yourself from STIs and HIV? For Infants and Children Who Weigh <45 kg: Erythromycin base or ethylsuccinate 50 mg/kg body weight/day orally divided into 4 doses daily for 14 days. It is more costly but also has lower frequency of gastrointestinal side effects (817). Prenatal screening and treatment of pregnant women is the best method for preventing chlamydial infection among neonates. For men, C. trachomatis urethral infection can be diagnosed by testing first-void urine or a urethral swab. WebChlamydia trachomatis. Reactive arthritis develops in a small percentage of individuals with chlamydial infection. 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. Although chlamydia incidence might be higher among certain women aged 25 years in certain communities, overall, the largest proportion of infection is among women aged <25 years (141). Preferred chlamydia treatment is a seven-day course of doxycycline, 100 mg taken by mouth twice per day. Untreated chlamydia infections can lead to serious health issues including pelvic inflammatory disease (PID) and infertility. The recommended treatment during pregnancy is erythromycin base or amoxicillin. 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. Centers for Disease Control and Prevention. 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. These cookies perform functions like remembering presentation options or choices and, in some cases, delivery of web content that based on self-identified area of interests. The most frequent clinical manifestation of chlamydial infection in males is urethritis, while the most common finding in females is cervicitis. Etiology, transmission and protection: Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infection (STI) globally. Multiple sequelae can result from C. trachomatis infection among women, the most serious of which include PID, ectopic pregnancy, and infertility. Doxycycline 100 mg orally 2 times/day for 7 days, Azithromycin 1 g orally in a single dose The most common bacterial sexually transmitted disease (STD) in the U.S., chlamydia is usually spread through vaginal, anal, and oral sex. For the first time there are diagnostic tests for Chlamydia trachomatis that are more sensitive than tissue culture. 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. Epidemiology, incidence and prevalence: The Mothers of infants who have ophthalmia caused by chlamydia and the sex partners of these women should be evaluated and presumptively treated for chlamydia (see Chlamydial Infection Among Adolescents and Adults). qualitative detection of ribosomal RNA (rRNA) from . 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. Physicians should obtain a sexual history free from assumptions about sex partners or practices. Because erythromycin effectiveness in treating pneumonia caused by C. trachomatis is approximately 80%, a second course of therapy might be required [833]. WebChlamydia trachomatis (/ k l m d i t r k o m t s /), commonly known as chlamydia, is a bacterium that causes chlamydia, which can manifest in various ways, including: trachoma, lymphogranuloma venereum, nongonococcal urethritis, cervicitis, salpingitis, pelvic inflammatory disease. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. Although data regarding the benefits of testing women with PID for M. genitalium and the importance of directing treatment against this organism are limited, the associations of M. genitalium with cervicitis and PID in cross-sectional studies using NAAT testing are consistent (928). WebChlamydia is one of the most common sexually transmitted infections (STIs). Rectal infections often are asymptomatic, although higher prevalence of M. genitalium has been reported among men with rectal symptoms. Asymptomatic infection is common among both men and women. This assay should not be used for the evaluation of suspected sexual abuse or other medico-legal investigations where chain of custody is required. 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). WebAbstract. M. genitalium infections among women are also frequently asymptomatic, and the consequences associated with asymptomatic M. genitalium infection are unknown.
