European guideline for the management of donovanosis, 2010

Area of Science:

• Infectious Diseases
• Microbiology
• Dermatology

Background:

• Donovanosis is a rare sexually transmitted infection (STI).
• Primarily observed in sporadic cases across Papua New Guinea, South Africa, India, Brazil, and Australia.
• The causative agent, Calymmatobacterium granulomatis, may be reclassified as Klebsiella granulomatis.

Purpose of the Study:

• To summarize the epidemiology, clinical presentation, diagnosis, and treatment of Donovanosis.
• To highlight the etiological agent and its proposed reclassification.
• To outline current diagnostic and therapeutic recommendations.

Main Methods:

• Literature review of Donovanosis cases and studies.
• Microscopic identification of Donovan bodies in stained tissue smears.
• Polymerase Chain Reaction (PCR) methods for diagnosis.

Main Results:

• The incubation period averages 50 days, progressing from papules to ulcers.
• Four lesion types are described: ulcerogranulomatous, hypertrophic, necrotic, and sclerotic.
• Azithromycin 1g weekly is the recommended treatment until healing.

Conclusions:

• Donovanosis requires accurate diagnosis through microscopy or PCR.
• Effective treatment with azithromycin is crucial for patient recovery.
• Understanding the epidemiology and clinical features aids in managing this rare STI.
