Q

Gonorrhea – Neisseria gonorrhoeae Microbiology (3)

A
  1. Etiologic agent: Neisseria gonorrhoeae
  2. Gram‐negative intracellular diplococcus
  3. Infects mucus‐secreting epithelial cells
2
Q

Gonorrhea Incidence (4)

A
  1. Significant public health problem in U.S.
  2. Number of reported cases underestimates incidence
  3. Incidence remains high in some groups defined by geography, age, race/ethnicity, or sexual risk behavior
  4. Increasing proportion of gonococcal infections caused by resistant organisms
3
Q

Gonorrhea Risk Factors (6)

A
  1. Multiple or new sex partners or inconsistent condom use
  2. Urban residence in areas with disease prevalence
  3. Adolescents, females particularly
  4. Lower socio‐economic status
  5. Use of drugs
  6. Exchange of sex for drugs or money

Q

Gonorrhea Transmission (6)

A

Efficiently transmitted by:

  1. Male to female via semen
  2. Female to male urethra
  3. Rectal intercourse
  4. Fellatio (pharyngeal infection)
  5. Perinatal transmission (mother to infant)
  6. Gonorrhea associated with increased transmission of and susceptibility to HIV infection
5
Q

Gonorrhea Manifestations in Men (8)

A
  1. Urethritis – Inflammation of urethra
  2. Symptoms (unlike Chlamydia)
  3. Typically purulent or mucopurulent urethral discharge
  4. Often accompanied by dysuria
  5. Discharge may be clear or cloudy or green
  6. Asymptomatic in 10% of cases
  7. Incubation period: usually 1‐14 days for symptomatic disease, but may be longer
  8. Epididymitis – Inflammation of the epididymis
    * Symptoms: unilateral testicular pain and swelling
    * Infrequent, but most common local complication in males
    * Usually associated with overt or subclinical urethritis
6
Q

Genital Infections in Women (3)

A
  1. Most infections are asymptomatic
  2. Cervicitis – inflammation of the cervix
  3. Urethritis – inflammation of the urethra
    a. Symptoms: dysuria, however, most women are asymptomatic
    b. 40%‐60% of women with cervical gonococcal infection may have urethral infection
7
Q

Gonorrhea Complications in Women (6)

A
  1. Accessory gland infection
  2. Bartholin’s glands
  3. Skene’s glands
  4. Pelvic Inflammatory Disease (PID)
  5. Fitz‐Hugh‐Curtis Syndrome
  6. Perihepatitis
8
Q

Syndromes in Men and Women (4)

A
  1. Anorectal infection
  2. Pharyngeal infection
  3. Conjunctivitis
  4. Disseminated gonococcal infection (DGI)
9
Q

Gonorrhea Clinical Considerations with suspected sexual abuse

A

In cases of suspected sexual abuse: Legal standard is culture with multiple tests to confirm the identity of Neisseria gonorrhoeae in children.

10
Q

Recommended tx of uncomplicated gonorrhea of cervix, urethra, and rectum (3)

A

Ceftriaxone 250mg IM once

PLUS

Azithromycin 1g PO once

OR

Doxycycline 100mg PO 2x/day for 7 days

11
Q

Treatment for Uncomplicated Gonococcal Infections of the Cervix, Urethra, and Rectum: Alternative Regimens (3)

A

If ceftriaxone is not available:

  1. Cefixime 400 mg orally in a single dose PLUS
  2. Azithromycin 1 g orally in a single dose
  3. In the case of azithromycin allergy, doxycycline (100 mg orally twice a day for 7 days) can be used in place of azithromycin as an alternative second antimicrobial when used in combination with ceftriaxone or cefixime
12
Q

Recommended tx of uncomplicated gonorrhea of pharynx (3)

A

Ceftriaxone 250mg IM once

PLUS

Azithromycin 1g PO once

OR

Doxyclin 100mg PO 2x/day for 7 days

13
Q

Gonorrhea Follow-Up (4)

A
  1. A test-of-cure is not needed for persons who receive a diagnosis of uncomplicated urogenital or rectal gonorrhea who are treated with any of the recommended or alternative regimens
  2. Any person with pharyngeal gonorrhea who is treated with an alternative regimen should return 14 days after treatment for a test-of cure using either culture or NAAT.
  3. If the NAAT is positive, effort should be made to perform a confirmatory culture before retreatment.
  4. All positive cultures for test-of-cure should undergo antimicrobial susceptibility testing.
14
Q

Gonorrhea Partner Management (4)

A
  1. Evaluate and treat all sex partners for N. gonorrhoeae and C. trachomatis infections if contact was within 60 days of symptoms or diagnosis.
  2. If a patient’s last sexual intercourse was >60 days before onset of symptoms or diagnosis, the patient’s most recent sex partner should be treated.
  3. Avoid sexual intercourse until therapy is completed and both partners no longer have symptoms.
  4. Remember that the law varies from state to state and changes about expedited care for partners
15
Q

Gonorrhea Reporting (2)

A
  1. Laws and regulations in all states require that persons diagnosed with gonorrhea are reported to public health authorities by clinicians, labs, or both.
  2. State will call and want to know about the patient
16
Q

A

Nature of disease:

  1. Usually symptomatic in males and asymptomatic in females
  2. Untreated infections can result in PID, infertility, and ectopic pregnancy in women and epididymitis in men
