PathogenThis section has been translated automatically.
Paracoccidioides brasiliensis (= Blastomyces brasiliensis), a dimorphic fungus that occurs in soil and dust.
Occurrence/EpidemiologyThis section has been translated automatically.
Spread over the entire South American continent, especially in Brazil and Latin America. Common in rural areas, therefore especially among farm and agricultural workers. Common in patients with immunosuppression (e.g. HIV infection).
EtiopathogenesisThis section has been translated automatically.
Infection with P. brasiliensis. The fungus lives in the soil and is transmitted to humans by inhalation through contaminated dust. Infection of healthy people through contact with infected people is not possible.
ManifestationThis section has been translated automatically.
Mostly 20 to 30 years of age, mostly white people. Men are 10 times more frequently affected than women.
Clinical featuresThis section has been translated automatically.
Initially infestation of the lungs, oral and nasal mucosa and the regional lymph nodes.
Beginning with cough and thoracic pain, followed by development of painful, ulcerative, granulomatous lesions of the oral and nasal mucous membranes. Facial skin affection mainly centrofacial: granulomatous, nodular, verruciform papules; later large, chronic, possibly mutating ulcers. Swelling and possibly purulent melting inflammation of the cervical lymph nodes is characteristic.
Hematogenous spread of the pathogens may involve bone, spleen, adrenal glands, CNS.
DiagnosisThis section has been translated automatically.
Microscopic and cultural pathogen detection from sputum, pus, bioptic material (by multilocular sprouting of the fungus in the yeast phase formation of characteristic "steering wheel" forms).
Differential diagnosisThis section has been translated automatically.
TherapyThis section has been translated automatically.
Amphotericin B (e.g. Amphotericin B) i.v. 1 mg/kg bw/day for 4-6 weeks, in severe cases liposomal Amphotericin B (e.g. AmBisome) initially 1 mg/kg bw i.v.; if necessary, increase gradually to 3 mg/kg bw i.v. until complete healing.
Alternatively: Itraconazole 100-400 mg/day in 1-2 ED p.o. or Ketoconazole 200-600 mg/day p.o. over 6 months, even if lesions heal earlier.
Progression/forecastThis section has been translated automatically.
Untreated lethal course.
