[Pleuropulmonary manifestations of amebiasis].
Amibiasis is the third leading cause of death due to parasitic infections in the world. Amibiasis is endemic in the warm regions of the world with deficient hygiene and socio-economic situations. Entamoeba histolytica is the causal agent of invasive amibiasis, unlike Entamoeba dispar which is not a pathogen for humans. Amibian colitis and amibian abscess of the liver are the most frequent intestinal and extra-intestinal manifestations. Pleuropulmonary complications almost always occur in patients with a liver abscess, the intrathoracic contamination via transphrenic dissemination predominating. Respiratory signs are inaugural in 80% of the cases. Pleuropulmonary ambiasis designates the localization of the amibian infestation, but the clinical expression may vary: pneumonia, lung abscess, pleurisy, hepatobronchial fistulization and more infrequently pulmonary embolism. The preferential localization is the right hemithorax related to abscess in the right lobe of the liver. Left lobe abscesses lead to left-sided pleuropulmonary complications with the risk of rupture into the pericardium. Chocolate-colored pus from a pleural or abscess puncture or vomitus strongly suggests the diagnosis, which is confirmed by highly-positive serology. Metronidazole is the treatment of choice, providing cure without sequellae. In Africa, mortality and morbidity due to ambiasis are high. In Abidjan, 92% of cured patients have sequella, and mortality reaches 15%, the consequence of late diagnosis.
