Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

Sleep Apnea Syndrome (SAS) is a common pathology affecting between 4 and 8% of the general population. It aggravates morbidity and cardio-metabolic mortality and is responsible for accidents related to vigilance disorders. It is estimated that 80%% of SAS cases are not diagnosed and therefore not treated. It is however impracticable to propose a diagnostic test of polygraphy (PG) or polysomnography (PSG) to every patient because of the cost and insufficient availability of these exams. It would therefore be useful to carry out a screening test before directing the patient to a complete test. Several simplified polygraph systems with 2 or 3 channels have been proposed (nasal cannula, oximetry, heart rate) but they generally record only one night and remain intrusive enough to perturb the sleep. The Withings HWA09 is a wrist-worn watch, which allows screening of SAS from four signals: movement, heart rate, breathing rate and blood oxygen saturation (SpO2). The objective of the present study is to validate the diagnostic performance of the Withings HWA09 for the detection of SAS compared to PSG.

The investigators decided to conduct a longitudinal study that compares the pulmonary tomographic patterns found in patients with viral pneumonia (i.e. influenza H1N1 and SARS-CoV-2) at a regional hospital. The primary aim of this study is to compare the radiological patterns found in patients with COVID-19 and influenza H1N1. The secondary aims of this study will assess the association between the radiological CT pattern and the need for invasive mechanical ventilation and mortality within the first 28 days of intensive care unit admission.

This study aims to investigate the characteristics of gut microbiome and metabolome in non-CF bronchiectasis patients, hoping to explore the underlying mechanisms as well as the influence of gut microbiota composition on bronchiectasis.

Patients confirmed COVID-19 with gastrointestinal manifestations will be included. Characteristics and outcomes will be described for them.

Elderly people constitute the largest proportion of emergency department (ED) patients, representing 12% of all ED admissions. The need for diagnostic tests or therapeutic interventions is much greater in this patient population. Cardiovascular diseases and symptoms represent 12% of the causes for ED admission, and patients suffering from cardiovascular disease are those whose ED visit lasts longest. The diagnostic approach in the ED in elderly patients admitted for acute dypsnoea is complex, and early identification of acute left-sided heart failure (ALSHF) is vital as it has an impact on prognosis. The clinical signs are difficult to interpret, and are non-specific, particularly at the acute phase and in elderly or obese patients. Indeed, some authors have reported up to 50% of diagnostic errors in elderly patients. Measure of the blood concentration of a natriuretic peptide allows a quick diagnosis. However, peptides alone suffer from several limitations, particularly in situations that are often encountered in elderly patients, such as sepsis, renal failure, acute coronary syndrome, pulmonary embolism, chronic respiratory failure, atrial fibrillation and high body mass index. Diagnostic performance deteriorates with increasing age, and there is a significant increase in this grey-zone in patients aged ≥75 years. In critical situations in elderly patients, assessment of natriuretic peptides serve mainly to rule out a diagnosis of left heart failure. Some authors have studied other biomarkers showing their performance in the diagnosis of ALSHF. These are biomarkers involved in remodeling and myocardial fibrosis (ST2, Galectin-3) or involved in myocardial injury (High-sensitivity Troponin-I). Therefore, a combined "multimarker" approach could improve the diagnostic performance of ALSHF. READ (NCT02531542) is a diagnostic study including patients over the age of 75 admitted to acute dyspnea in the ED, to demonstrate the superiority of an ultrasound protocol (the READ protocol) on NT-proBNP in the ALSHF diagnosis. The hypothesis is that the diagnostic accuracy of a multimarker diagnostic approach, namely the READ-MA method, combining NT-proBNP, High-sensitivity Troponin-I, ST2 and Galectin-3 would be superior to that of NT-proBNP assessment for the diagnosis of ALSHF in elderly patients (≥75 years) admitted to the ED.

The main objective is to describe the phenotypic features of the paediatric and adult patients with Idiopathic Interstitial Pneumopathy/Pneumopathy Interstitial Diffuse (IIP/PID), at diagnosis and during the follow-up. These data will be critical for the description of the natural history of the various forms of IIP/PID.

Validation of biomolecular markers in the circulation and radiomic features are the focus of this project.The aim is to assess the role of molecular and cellular biomarkers (exosomes antigens, Circulating tumor cells - CTCs, panel of mutations in circulating free DNA) and radiomic signature, as complementary to assist early detection of lung cancer by LDCT.

To describe the radiological presentation of brain abnormalities in COVID-19 + patients

Patients with the acute respiratory distress syndrome (ARDS) have markedly varied clinical presentations. Main characteristics of mechanically ventilated ARDS caused by COVID-19, and adherence to lung-protective ventilation strategies are not well known.

Electrocardiographic (ECG) evaluation of patients with severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection. The present study involves three different phases of evaluation of the ECG traces of hospitalized patients with SARS-CoV-2 infection. Phase 1: it is proposed to collect and retrospectively analyze the ECGs of hospitalized patients with severe SARS-CoV-2 infection which led to invasive ventilation or patient death as a consequence and, if available, also possible troponin dosage; Phase 2: aims to collect and analyze the ECGs of consecutive hospitalized patients with SARS-CoV-2 infection and evaluate their relationship with the course of the disease, cardiac involvement and prognosis; Phase 3: it is proposed to repeat ECG and to carry out echocardiogram to patients with SARS-CoV-2 infection after 3 months from hospital discharge by simultaneously performing, if deemed clinically indicated, also cardiac magnetic resonance. In this phase, any evolutions of ECG alterations of the acute phase will be described and the relationship with cardiac involvement will be assessed.
