Pneumocystis jirovecii causes pneumonia in immunosuppressed individuals. However, it has been reported the detection of low levels of Pneumocystis DNA in patients without signs and symptoms of pneumonia, which likely represents colonization. Several studies performed in animals models and in humans have demonstrated that Pneumocystis induces a local and a systemic response in the host. Since P. jirovecii colonization has been found in patients with chronic pulmonary diseases it has been suggested that P. jirovecii may play a role in the physiopathology and progression of those diseases. In this report we revise P. jirovecii colonization in different chronic pulmonary diseases such us, chronic obstructive pulmonary disease, interstitial lung diseases, cystic fibrosis and lung cancer.
Résumé
Pneumocystis jirovecii est un agent de pneumonie chez les sujets immunodéprimés. Des faibles taux d’ADN de Pneumocystis peuvent cependant être détectés chez des patients sans pneumonie ; ils correspondraient à des situations de colonisation. Plusieurs études développées chez l’animal et chez l’homme ont montré que la colonisation par Pneumocystis peut induire chez l’hôte des réponses locale et systémique. Comme la colonisation peut être observée chez des patients atteints d’affections pulmonaires chroniques, il a été suggéré que P. jirovecii pourrait jouer un rôle dans la physiopathologie et l’aggravation de ces maladies. Dans cette revue, nous examinons la colonisation par P. jirovecii chez des patients atteints de maladies pulmonaires chroniques comme la bronchopneumopathie chronique obstructive, les fibroses pulmonaires interstitielles, la fibrose kystique et le cancer du poumon.
