Neisseria gonorrhoeae

(Redirected from Gonococcal)

Background

Clinical Features

Differential Diagnosis

Sexually transmitted diseases

Vesiculobullous rashes

Febrile

Afebrile

Evaluation

Workup

  • Dependent upon the infected organ
  • PCR or culture on Thayer-Martin agar (most common)

Management

Presumed GC/chlamydia of cervix, urethra, or rectum (uncomplicated)[1]

Typically, treatment for both gonorrhea and chlamydia is indicated, if one entity is suspected.

Standard

  • Gonorrhea
    • Ceftriaxone IM x 1
      • 500 mg, if weight <150 kg
      • 1 g, if weight ≥150 kg
  • Chlamydia


Ceftriaxone contraindicated

^Additional chlamydia coverage only needed if treated with cefixime only

Partner Treatment

Presumed GC/chlamydia of the pharynx (uncomplicated)[2]

Standard
Typically, treatment for both gonorrhea and chlamydia is indicated, if one entity is suspected.

  • Gonorrhea
    • Ceftriaxone IM x 1
      • 500 mg, if weight <150 kg
      • 1 g, if weight ≥150 kg
  • Chlamydia


Ceftriaxone contraindicated

  • No reliable alternative treatments are available for pharyngeal gonorrhea
    • For persons with a history of a beta-lactam allergy, a thorough assessment of the reaction is recommended.[3]
    • For persons with an anaphylactic or other severe reaction (e.g. Stevens Johnson syndrome) to ceftriaxone, consult an infectious disease specialist for an alternative treatment recommendation.

Key

  • S susceptible/sensitive (usually)
  • I intermediate (variably susceptible/resistant)
  • R resistant (or not effective clinically)
  • S+ synergistic with cell wall antibiotics
  • U sensitive for UTI only (non systemic infection)
  • X1 no data
  • X2 active in vitro, but not used clinically
  • X3 active in vitro, but not clinically effective for Group A strep pharyngitis or infections due to E. faecalis
  • X4 active in vitro, but not clinically effective for strep pneumonia
