'''Paracoccidioidomycosis''' (also known as '''Lutz-Splendore-Almeida disease''' or '''Brazilian blastomycosis''') is a [[mycosis]] caused by the [[fungus]] ''[[Paracoccidioides brasiliensis]]''. Sometimes called ''South American blastomycosis'', paracoccidioidomycosis is caused by a different fungus than that which causes [[blastomycosis]].

== Agent==
==[[Paracoccidioidomycosis overview|Overview]]==
''P. brasiliensis'' is a thermally-dimorphic fungus distributed in Brazil and South America. The habitat of the infectious agent is not known but appears to be aquatic. In [[biopsies]] the fungus appears as a polygemulating<!-- not a real word? --> yeast with a pilot's wheel-like appearance.


== Disease==
==[[Paracoccidioidomycosis historical perspective|Historical Perspective]]==
Paracoccidioidomycosis is a [[systemic mycosis]] caused by the dimorphic fungus Paracoccidioides. It frequently involves [[mucous membrane]]s, [[lymph node]]s, bone and lungs and requires some degree of host [[immunosuppression]].


Primary infection is thought to be autolimited and almost asymptomatic as [[histoplasmosis]] or Valley Fever. In young people, there is a progressive form of the disease (akin of tuberculous [[septicemia]] in tuberculous priminfection) with high prostrating fever, generalized [[lymphadenopathy]] and pulmonary involvement with milliary lesions. This juvenile form has a more severe prognosis even with treatment. The most common form is the so called adult form of paracoccidioidomycosis that is almost certainly a reactivation of the disease.
==[[Paracoccidioidomycosis classification|Classification]]==


Painful lesions with a violaceous hue in lips and oral mucosa are common as is cervical lymphadenitis teeming with polygemulating yeasts in the biopsy. In this form, differential diagnosis must be made with mucocutaneous [[leishmaniasis]], [[yaws]] and [[Tuberculosis|TB]].
==[[Paracoccidioidomycosis pathophysiology|Pathophysiology]]==


[[Pulmonary]] involvement is also common, it starts as [[lobar pneumonia]] or [[pleurisy]] but without remission at ninth day; the patient remains [[febrile]], [[cough]]s, [[loses weight]] and the [[X rays]] reveal milliary shadows throughout lung fields. Other organs can be involved, like bones, [[meninges]], arteries and [[spleen]] but this is very rare.
==[[Paracoccidioidomycosis causes|Causes]]==


Diagnosis is made with a biopsy of affected tissue, this shows the characteristic helm-shaped yeasts and culture shows the agent. Serology is also used in endemic areas.
==[[Paracoccidioidomycosis differential diagnosis|Differentiating Paracoccidioidomycosis From Other Diseases]]==


== Treatment==
==[[Paracoccidioidomycosis epidemiology and demographics|Epidemiology and Demographics]]==
[[Sulphonamide]]s are the traditional remedies to paracoccidiodomycosis. They were introduced by Oliveira Ribeiro and used for more than fifty years with good results. The most used [[sulfa drugs]] in this infection are sulfadimethoxime, [[sulfadiazine]] and [[co-trimoxazole]]. This treatment is generally safe but several adverse effects can appear, the most severe of which are the [[Stevens Johnson Syndrome]] and [[agranulocytosis]]. It must be continued for up to 3 years to obtain cure and relapse and treatment failures aren't unusual.


Antifungal drugs like [[Amphotericin B]] or [[Ketoconazole]] are also effective in clearing the infection but they are very expensive compared with sulphonamides.
==[[Paracoccidioidomycosis risk factors|Risk Factors]]==


During therapy [[fibrosis]] can appear and a surgery be needed to correct this. Other possible complication is Addisonian crisis. The death rate is around ten percent.
