Factors associated with Pneumocystis colonization and circulating genotypes in chronic obstructive pulmonary disease patients with acute exacerbation…
2021
Abstract Pneumocystis jirovecii colonization is frequent during chronic obstructive pulmonary disease (COPD) and patients constitute potential contributors to its interhuman circulation. However, the existence of an environmental reservoir cannot be excluded. We assessed the prevalence and factors associated with Pneumocystis colonization during COPD, and studied circulation between patients and their domestic environment. Pneumocystis molecular detection and mtLSU genotyping were performed in oro-pharyngeal washes (OPW) sampled in 58 patients with COPD acute exacerbation, and in indoor dust, sampled in patients’ homes using electrostatic dust collectors (EDCs). Lung and systemic inflammati…
Clinical significance of Pneumocystis jirovecii DNA detection by real-time PCR in hematological patient respiratory specimens

Evaluation of the Amplex eazyplex Loop-Mediated Isothermal Amplification Assay for Rapid Diagnosis of Pneumocystis jirovecii Pneumonia
2020
ABSTRACT Quantitative PCR (qPCR) assays are the gold standard for diagnosis of Pneumocystis jirovecii pneumonia (PCP). However, they are laborious and require skilled personnel. Therefore, execution outside regular working hours of the molecular biology laboratory is limited. The eazyplex P. jirovecii assay (PJA) uses loop-mediated isothermal amplification for detection of P. jirovecii. It is performed directly with respiratory specimens, without the need for special skills, and delivers a result within 3 to 25 min. The goal of our study was to compare the performance of the eazyplex PJA with that of established P. jirovecii qPCR assays. All archived bronchoalveolar lavage fluid (BALF) samp…
Criptococosis sistémica y neumocistosis en un paciente VIH-positivo
1995
La criptococosis es una de las principales infecciones oportunistas que afectan a los enfermos de sida. Las manifestaciones neurologicas constituyen la forma mas frecuente de manifestarse esta infeccion fungica, siendo la afectacion pulmonar mucho menos aparente clinicamente. Se presenta el caso de un paciente atendido en urgencias del hospital, con un cuadro de insuficiencia respiratoria aguda, que evoluciono fatalmente. Los estudios microbiologicos e histopatologicos demostraron la presencia simultanea de Cryptococcus neoformans y de Pneumocystis carinii en pulmon. Se discute esta forma de presentacion de la criptococosis, en ausencia de sintomatologia neurologica, y la trascendencia de l…
