Study Notes
Clinical Features of Gonococcal Urethritis
- Male: characterized by purulent urethral discharge and burning urination
- Physical examination: purulent (yellowish) urethral exudates, erythema of the meatus
- Female: usually asymptomatic, but may present with vaginal discharge, dysuria, cervisitis, and edema with induced bleeding
Diagnosis of Gonococcal Urethritis
- Suspected clinically, confirmed by smear, and made definitely by culture or PCR
- Smear: intracellular (neutrophil) gram negative diplococci
- Culture: performed on modified Thayer-Martin media
- PCR: more sensitive than culture
Non-Gonococcal Urethritis (NGU)
- Diagnosed when there is a clinical feature of urethritis without detection of a gram negative, intracellular, diplococci organisms on microscopic examination
- Causes:
- Infectious: Chlamydial urethritis, ureaplasma urealyticum, E.coli, Proteus, herpes simplex, intraurethral warts, candidiasis, Trichomonas vaginalis
- Non-infectious: drug allergy, food, chemical, idiopathic urethritis
Chlamydial Urethritis
- Caused by Chlamydia trachomatis, a non-motile, gram negative, intracellular organism
- Diagnosis: serological tests, PCR (has largely replaced culture)
- Clinical features: longer incubation period, more gradual presentations, fewer and thicker discharge
Management of Urethritis
- History: symptoms, sexual history, type of contraception, and drug and food history
- Examination: type of discharge, meatal erythema
- Investigation: GUE, smear, culture, and PCR
- Treatment:
- GC urethritis: single dosage of Ceftriaxone, cefixime, or ciprofloxacin
- Chlamydial urethritis: Azithromycin or doxycycline for 7 days
- Importance of treating sexual partners to prevent re-infection
Complications of STIs
- Pregnancy complications: ectopic pregnancy, miscarriage
- Newborn complications: prematurity, congenital and neonatal infections
- Infertility: mostly in females (fallopian tube obstruction)
- Urethral stricture: due to gonococcal urethritis
- Malignancy: mostly cervical and rarely penile carcinoma (SCC)
Genital Discharge Causes
- Urethral discharge: Gonococcal urethritis, non-gonococcal urethritis
- Vaginal discharge: ST causes (candidal vaginitis, trichomonal vaginitis), non-ST causes (physiological, cervical erosions, tumors)
Gonococcal Urethritis (Gonorrhea) Microbiology
- Caused by Niesseria gonorrhoeae, an intracellular, gram negative, kidney-shaped diplococcus
- Short incubation period (2-5 days)
- Pathogenesis: primarily infects columnar epithelium (urethra, cervix, vagina, pharynx, conjunctiva, rectum)
Epidemiology of STIs
- Most common in young, sexually active people
- Underreporting is common
- More common in males, but more serious in females
- Control and prevention: early and accurate diagnosis, early and effective treatment, counseling, STIs screening, condoms, vaccines, and nonoxynol-9
