Gonorrhea
Gonorrhea in males typically presents as urethral discomfort, dysuria, and discharge.
- The degree of discomfort and discharge are variable.
- Asymptomatic infection is common among females, but may also occur in males.
- Gonococcal epididymitis presents with unilateral pain and swelling localized posteriorly within the scrotum.
- Gonorrhea in the female are usually manifest as vaginal discharge and endocervicitis.
- The discharge is thin, purulent and mildly odorous.
- Dysuria or a scant urethral discharge may be present.
- Non-gonococcal urethritis, including infection by Chlamydia trachomatis and other Neisseria species may mimic gonococcal infection.
- Infection can be passed to the male urethra from the pharynx through fellatio.
- Levels of serum Prostate-specific Antigen (PSA) may be elevated in patients with gonorrhea.
Gonococcal Pelvic Inflammatory Disease
Pelvic or lower abdominal pain suggests infection of the endometrium, fallopian tubes, ovaries or peritoneum.
- Pain may be midline, unilateral, or bilateral.
- Fever and vomiting may be present.
- Right upper quadrant pain from perihepatitis (Fitz-Hugh-Curtis syndrome) may occur following the spread of organisms upward along peritoneal planes to the hepatic capsule (The syndrome is also reported as a complication of gonorrhea in males)
Other Clinical Forms
- Gonococcal proctitis is often asymptomatic, but rectal pain, pruritus, tenesmus, bloody diarrhea and rectal discharge may be present.
- Gonococcal pharyngitis may be asymptomatic, or associated with severe inflammation. Neisseria gonorrhoeae is often present in throat specimens from patients with urethritis.
- Gonococcal conjunctivitis is usually unilateral in adults; however, neonatal infection (ophthalmia neonatorum) involves both eyes.
- Symptoms include pain, redness, and a purulent discharge and may result in blindness.
- Rare instances of corneal perforation are reported.
- Disseminated gonococcal infection is characterized by joint or tendon pain, of single or multiple joints.
- Severe pain, swelling, and decreased mobility in a single joint (usually the knee) suggest purulent arthritis.
- Tenosynovitis is common, usually affecting the small joints of the hands.
- A rash is present in 25% of patients with gonococcemia.
- Additional complications include meningitis, endocarditis, septic shock with ARDS, subcutaneous abscess, Fournier’s gangrene, pyomyositis and other localized infections.
