Patients usually have unilateral testicular pain with scrotal erythema, tenderness, or swelling over the epididymis. Resistance to azithromycin has been rapidly increasing and has been confirmed in multiple studies. Chlamydia trachomatis infection most commonly affects the urogenital tract. To observe the discharge, the penis may need to be milked by applying pressure from the base of the penis to the glans. 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. Symptoms. Data regarding effectiveness of azithromycin in treating chlamydial pneumonia are limited. We take your privacy seriously. Copyright 2023 American Academy of Family Physicians. Sensitive and specific methods for diagnosing chlamydial ophthalmia in the neonate include both tissue culture and nonculture tests (e.g., DFA tests and NAATs). The most common bacterial sexually transmitted disease (STD) in the U.S., chlamydia is usually spread through vaginal, anal, and oral sex. Furthermore, treating their sex partners can prevent reinfection and infection of other partners. Exposure to C. trachomatis during delivery can cause ophthalmia neonatorum (conjunctivitis) in neonates or chlamydial pneumonia at one to three months of age. Data are limited regarding use of minocycline in instances of treatment failure (966). Neonatal ocular prophylaxis with erythromycin, the only agent available in the United States for this purpose, is ineffective against chlamydial ophthalmia neonatorum (or pneumonia) (833). Even when symptoms occur, they're often mild. 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). 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. Multiple sequelae can result from C. trachomatis infection among women, the most serious of which include PID, ectopic pregnancy, and infertility. Having partners accompany patients when they return for treatment is another strategy that has been used successfully for ensuring partner treatment (see Partner Services). Most women with chlamydial infection have minimal or no symptoms, but some develop pelvic inflammatory disease. Methods: The clinical data of 92 patients diagnosed with Chlamydia trachomatis (C. trachomatis) infections were WebC trachomatis can be transmitted from the mother during delivery and is associated with conjunctivitis and pneumonia in the newborn. A test of cure to detect therapeutic failure ensures treatment effectiveness and should be obtained at a follow-up visit approximately 4 weeks after treatment is completed. Sexually active adolescents and adults at increased risk of acquiring a sexually transmitted infection should receive behavioral counseling to reduce their risk. Chlamydia 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. Moreover, using chlamydial NAATs at <4 weeks after completion of therapy is not recommended because the continued presence of nonviable organisms (553,818,819) can lead to false-positive results. Patients should be advised to abstain from sexual intercourse for seven days after treatment initiation. 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). Collection of larger volumes of urine may result in rRNA target dilution that may reduce test sensitivity. Risk for HIV infection is increased among women with M. genitalium, and evidence indicates that HIV shedding occurs more often among persons with M. genitalium and HIV infection who are not taking ART than among persons without M. genitalium (942,944). Physicians should create supportive spaces where patients feel safe sharing information by using open-ended questions; avoiding assumptions regarding sexual preferences, practices, and gender/sex; and normalizing diverse sexual experiences. The arthritis begins one to three weeks after the onset of chlamydial infection. Copyright 2006 by the American Academy of Family Physicians. All nonpregnant people should be tested for reinfection approximately three months after treatment or at the first visit in the 12 months after treatment. MSM who are HIV negative with a rectal chlamydia diagnosis should be offered HIV PrEP. Prevalence of M. genitalium among women with PID ranges from 4% to 22% (925,926) and was reported as 60% in one study of women with postabortal PID (918). This is a corrected version of the article that appeared in print. To minimize risk for reinfection, patients also should be instructed to abstain from sexual intercourse until all of their sex partners have been treated. However, when gonorrhea testing is performed at the oropharyngeal site, chlamydia test results might be reported because certain NAATs detect both bacteria from a single specimen. Erythromycin is no longer recommended because of the frequency of gastrointestinal side effects that can result in therapy nonadherence. Persons who have M. genitalium and HIV infection should receive the same treatment regimen as those persons without HIV. Testing can be performed on a sample obtained from the nasopharynx. However, perinatally transmitted C. trachomatis infection of the nasopharynx, urogenital tract, and rectum can persist for 23 years (see Sexual Assault or Abuse of Children). Etiology, transmission and protection: Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infection (STI) globally. You can review and change the way we collect information below. 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 Chlamydial and Gonococcal Infections: Screening, 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. 2. 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. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. 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). The joint involvement is asymmetric, with multiple affected joints and a predilection for the lower extremities. 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). Finally, C trachomatis may cause Because of the implications of a diagnosis of C. trachomatis infection in a child, only CLIA-validated, FDA-cleared NAAT should be used for extragenital site specimens (837). treatment 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). These infants should receive evaluation and age-appropriate care and treatment. Treatment with azithromycin alone has been reported to select for resistance (705,954,955), with treatment of macrolide-susceptible infections with a 1-g dose of azithromycin resulting in selection of resistant-strain populations in 10%12% of cases. It is caused by Chlamydia trachomatis bacteria which infects both men and women. Chlamydia trachomatis are gram-negative anaerobic bacteria that replicate inside eukaryotic cells (Mohseni, 2019). It is a weak organism that relies on its host for nutrients and survival. It lives inside a host in order to reproduce and survive. They help us to know which pages are the most and least popular and see how visitors move around the site. 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. 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.

Physical findings of urogenital chlamydial infection in women include cervicitis with a yellow or cloudy mucoid discharge from the os. The association with PID is supported by early studies among nonhuman primates that determined that endosalpingitis develops after inoculation with M. genitalium (927). Using the Aptima assays as reference method, the comparison showed that the average specificity of multiplex RT-PCR was 100.0% for the four For men, C. trachomatis urethral infection can be diagnosed by testing first-void urine or a urethral swab. 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. Ocular specimens from neonates being evaluated for chlamydial conjunctivitis also should be tested for N. gonorrhoeae (see Ophthalmia Neonatorum Caused by N. gonorrhoeae). All women who are 25 years or younger or at increased risk of sexually transmitted diseases should be screened for chlamydial infection annually. Chlamydia is a treatable infection. 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. 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). Available evidence supports that doxycycline is efficacious for C. trachomatis infections of urogenital, rectal, and oropharyngeal sites. Because chlamydia often doesnt cause symptoms, many people who have chlamydia dont know it and unknowingly infect other people. Tracheal aspirates and lung biopsy specimens, if collected, should be tested for C. trachomatis. All information these cookies collect is aggregated and therefore anonymous. Doxycycline should be used to treat chlamydia in nonpregnant people. 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). In the absence of laboratory results in a situation with a high degree of suspicion of chlamydial infection and the mother is unlikely to return with the infant for follow-up, exposed infants can be presumptively treated with the shorter-course regimen of azithromycin 20 mg/kg body weight/day orally, 1 dose daily for 3 days. 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.
