Chlamydia

Introduction

  • Chlamydia is a common sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis.
  • It often presents with mild or no symptoms but can lead to serious complications if untreated, including infertility.
  • Early detection and treatment with antibiotics can effectively cure the infection and prevent complications.

Causes of Chlamydia

  • Transmission
    • Spread through vaginal, anal, or oral sexual contact with an infected person.
    • Can also be transmitted from mother to baby during childbirth, causing neonatal infections like conjunctivitis or pneumonia.

Symptoms of Chlamydia

  1. In Women
    • Abnormal vaginal discharge (watery or yellowish).
    • Painful urination.
    • Pelvic pain or lower abdominal pain.
    • Bleeding between periods or after sex.
    • Pain during intercourse.
  2. In Men
    • Discharge from the penis (white, cloudy, or watery).
    • Painful urination.
    • Testicular pain or swelling.
  3. In Both Genders
    • Rectal pain, discharge, or bleeding (if infection involves the rectum).
    • Throat discomfort or soreness (rare, from oral transmission).
  4. Asymptomatic Cases
    • Up to 70% of women and 50% of men may have no symptoms.

Complications of Untreated Chlamydia

  1. In Women
    • Pelvic Inflammatory Disease (PID).
    • Chronic pelvic pain.
    • Infertility due to fallopian tube damage.
    • Ectopic pregnancy.
  2. In Men
    • Epididymitis (inflammation of the epididymis).
    • Reduced fertility in severe cases.
  3. In Both Genders
    • Reiter’s syndrome (reactive arthritis): Joint pain, urethritis, and conjunctivitis.
    • Increased risk of contracting or transmitting HIV.
  4. In Newborns
    • Conjunctivitis or pneumonia.

Diagnosis of Chlamydia

  1. Nucleic Acid Amplification Test (NAAT)
    • Highly sensitive and specific test for detecting Chlamydia trachomatis.
    • Performed on urine samples or swabs from the cervix, urethra, rectum, or throat.
  2. Urine Tests
    • First-catch urine samples for men and women.
  3. Swab Tests
    • Cervical swabs in women.
    • Urethral swabs in men.

Treatment Options for Chlamydia

1. Antibiotic Therapy

  • First-Line Treatments
    • Azithromycin: 1 g orally in a single dose.
    • Doxycycline: 100 mg orally twice daily for 7 days.
  • Alternative Antibiotics (if allergic or resistant)
    • Erythromycin.
    • Levofloxacin.
  • For Rectal Chlamydia
    • Doxycycline is preferred for better efficacy.

2. Partner Notification and Treatment

  • Sexual partners should be notified, tested, and treated to prevent reinfection.

3. Special Considerations

  • Pregnancy
    • Azithromycin is safe and effective.
    • Avoid doxycycline due to risks of fetal harm.
  • Neonates
    • Erythromycin for neonatal conjunctivitis or pneumonia.
  • Reinfection Prevention
    • Abstain from sexual activity until 7 days after completing treatment.

Prevention Strategies

  • Consistent and correct use of condoms during sexual activity.
  • Regular STI screening, especially for sexually active individuals under 25 or with multiple partners.
  • Education on safe sexual practices and the importance of partner testing.

Monitoring Parameters

  • Symptom Resolution: Symptoms should improve within a week after starting treatment.
  • Follow-Up Testing: Repeat testing 3 months after treatment to rule out reinfection, especially for high-risk individuals.
  • Partner Notification: Confirm that sexual partners have been treated.

Patient Counseling Points

  • Adherence to the full antibiotic course is crucial for effective treatment.
  • Avoid sexual contact during the treatment period and until all partners are treated.
  • Educate on the risk of reinfection and importance of regular screening.
  • Emphasize the asymptomatic nature of the infection to encourage proactive testing.

Use in Children

  • Neonates may require treatment for conjunctivitis or pneumonia caused by maternal transmission.

Use in Pregnancy

  • Safe treatment options like azithromycin or amoxicillin should be used to protect both mother and fetus.

Use in Elderly

  • Rare but may occur; treatment follows standard guidelines.
