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…

The first step of the project was the conduction of separated systematic reviews of the characteristics and applicability to critically ill, adult patients outside classical populations at ri…
Rituximab for Immune Thrombocytopenia: A Retrospective Analysis on the Role of Prophylaxis Against Pneumocystis Jirovecii and Herpes Zoster Virus
2018
Abstract Introduction and objective of the study Rituximab (RTX) is considered a valid second line treatment option for persistent or chronic Immune Thrombocytopenia (ITP). RTX is known to affect the immune system thus increasing the risk for viral and fungal infections. Although prophylactic treatment to prevent Pneumocystis jirovecii (PJ) and herpes viruses' infections is used in patients with haematological neoplasms receiving RTX, these evidence is lacking in ITP patients candidated to anti-CD20 therapy. We here reported the role of phrophylaxis in a cohort of patients treated with RTX for refractory/relapsed ITP. Methods Data from patients affected by ITP and treated at our Institution…
