Symptoms and Treatment of Chlamydia

Chlamydia is often asymptomatic in over 80% of cases, but when symptoms occur, they typically include urethritis in men and cervicitis in women, which may present as discharge or dysuria. 1, 2

Symptoms of Chlamydia

In Men:

  • Urethritis (most common manifestation)
    • Urethral discharge
    • Dysuria (painful urination)
    • Often mild or absent symptoms compared to gonorrhea 3
  • Epididymitis (accounts for 50% of outpatient visits for this condition among young men) 1
  • Proctitis in men who engage in receptive anal intercourse
    • Rectal discharge
    • Pain during defecation 3

In Women:

  • Often asymptomatic (up to 80% of cases)
  • Cervicitis
  • Urethral syndrome (acute dysuria-pyuria syndrome)
  • Abnormal vaginal discharge
  • Intermenstrual bleeding
  • Post-coital bleeding

Complications:

  • In women:

    • Pelvic inflammatory disease (PID)
    • Salpingitis
    • Perihepatitis (Fitz-Hugh-Curtis syndrome)
    • Tubal factor infertility
    • Ectopic pregnancy 1, 2
  • In men:

    • Epididymitis
    • Orchitis
    • Reactive arthritis (Reiter's syndrome) 1, 4
  • Other manifestations:

    • Conjunctivitis
    • Reactive arthritis (in both men and women)
    • Pharyngeal infection (though not established as a cause of pharyngitis) 3

Treatment of Chlamydia

Recommended Regimens:

  • Azithromycin 1g orally in a single dose OR
  • Doxycycline 100mg orally twice a day for 7 days 3, 1

Alternative Regimens:

  • Erythromycin base 500mg orally four times a day for 7 days
  • Erythromycin ethylsuccinate 800mg orally four times a day for 7 days
  • Ofloxacin 300mg orally twice a day for 7 days 3

Special Considerations:

  • For pregnant women:
    • Erythromycin base 500mg orally four times a day for at least 7 days
    • Amoxicillin 500mg orally three times a day for 7 days 1, 5

Management Guidelines:

  1. Partner notification and treatment is essential - all sexual partners from the past 60 days should be evaluated and treated 3, 1

  2. Abstinence from sexual intercourse until:

    • 7 days after single-dose therapy, OR
    • Until completion of 7-day regimen
    • Until all sex partners are treated 3
  3. Retesting is recommended approximately 3 months after treatment to prevent reinfection 1

  4. Medications should be dispensed on site when possible, with the first dose directly observed to maximize compliance 3

Important Clinical Considerations:

  • Azithromycin provides single-dose, directly observed therapy, which may be more cost-effective in populations with poor compliance
  • Doxycycline costs less than azithromycin but requires a 7-day regimen
  • Erythromycin is less efficacious and has more gastrointestinal side effects that may reduce compliance 3
  • Screening is recommended for all sexually active women under 25 years, pregnant women, and those at increased risk 1, 4

Prevention:

  • Consistent condom use reduces transmission risk
  • Regular screening for high-risk individuals
  • Treatment of all sexual partners to prevent reinfection 1

Remember that untreated chlamydia can lead to serious complications, particularly in women, where it can cause long-term reproductive health issues. Early detection and treatment are crucial for preventing these complications.
