Study Notes
Chlamydia and Gonorrhea: Key Facts and Context
- Chlamydia was not recognized as a sexually transmitted disease until recently due to symptoms resembling other pathologies.
- Chlamydia is the most prevalent sexually transmitted disease in the United States, with approximately four million cases annually, mostly in individuals under 25 years old.
- Direct and indirect costs of chlamydia total $24 billion a year, mainly due to complications.
- The life cycle of C. trachomatis consists of two stages: elementary body (EB) and reticulate body (RB), with an incubation period of 7-21 days in the host.
- Chlamydia trachomatis elementary bodies infect the cervix, leading to few or no clinical symptoms, and can cause pelvic inflammatory disease, tubal inflammation, scarring, and infertility in women.
- Symptoms of chlamydia in men may include discharge from the penis, burning when urinating, and mild or unnoticed symptoms in many cases.
- In women, symptoms may include vaginal discharge, chronic abdominal pain, bleeding between menstrual periods, and low-grade fever, with 80% of women having no noticeable symptoms until complications set in.
- Treatment for chlamydia includes tetracyclines, doxycycline, azithromycin, erythromycin, sulfisoxazole, and amoxicillin.
- Azithromycin eradicates genital but not gastrointestinal infection, leading to reemergence of symptoms in some cases.
- Neisseria gonorrhoeae causes gonorrhea and is a significant cause of acute bacterial meningitis, with high prevalence and low mortality.
- Gonorrhea practically always involves mucous membranes of the urethra, resulting in a copious discharge of pus, more obvious in males than females.
- Neisseria gonorrhoeae was first described in 1879 and its etiological relationship to human disease was later established using human volunteers to fulfill Koch's postulates.
