Visceral leishmaniasis in a lung transplant recipient: usefulness of highly sensitive real-time polymerase chain reaction for preemptive diagnosis.

We report the case of a lung transplant recipient in whom the diagnosis of visceral leishmaniasis (VL) was made by detection of parasites in a peripheral blood smear when the parasite load already reached 8.9 × 10(3) parasites/mL. We demonstrated that the VL diagnosis could have been done months before the development of symptoms by the use of Leishmania-specific real-time polymerase chain reaction (PCR), suggesting the role of preemptive PCR-based diagnosis in transplant recipients at risk for VL

Biomarqueurs systèmiques pour les infections respiratoires [Systemic biomarkers in respiratory tract infections]

Respiratory tract infections represent a major cause of morbidity and mortality despite the progress made in their diagnosis and treatment. Since the clinical presentation of a viral or bacterial infection is often similar, the identification of a biomarker that could guide the clinician whether or not to introduce an antibiotic therapy is crucial. C-reactive protein and procalcitonin are the most commonly used biomarkers as a diagnostic tool for respiratory tract infections. New biomarkers show promising results for assessing the severity of infection and identifying patients at risk for complications. However, the use of biomarkers has limitations and the diagnosis of a bacterial infection should not be based solely on the measurement of a biomarker

Successful pregnancy in a cystic fibrosis patient with a severe impairment of lung function receiving Elexacaftor-Tezacaftor-Ivacaftor.

Before the arrival of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) modulators women with CF and impaired lung function were experiencing a high risk of complications and mortality during and the years after pregnancy. The arrival of the highly efficient CFTR modulator, Elexacaftor-Tezacaftor-Ivacaftor (ETI) resulted in an improvement of lung function, quality of life and fertility. Here we report a case of successful pregnancy and uncomplicated delivery for a CF patient with severely impaired lung function receiving ETI prior to conception

Quand penser à la transplantation pulmonaire ? [When to consider lung transplantation?]

Pulmonary transplantation remains the ultimate therapeutic option for selected patients with an advanced pulmonary disease and terminal respiratory insufficiency when all other therapeutic options have been exhausted. The optimal time-frame to proceed to a first discussion and evaluation about lung transplantation may be difficult to determine. This article describes the pathway of a patient towards lung transplantation and summarizes the criteria, which may help to timely identify eligibility for this therapeutic modality. We will focus mainly on the 2021 update of the International Society for Heart and Lung Transplantation (ISHLT) recommendations for the selection of lung transplant candidates
