Filter by:In the late 2019 a new Coronavirus was identified as the cause of a group of atypical interstitial pneumonia cases in Wuhan, a city in the Chinese province of Hubei. In February 2020, the World Health Organization designated COVID-19 disease, which stands for Coronavirus 2019 disease. Following the progressive spread of the infection in other countries of the world, WHO declared the Pandemic on 11 March 2020. Italy was the first European country involved in the spread of the infection and among those with the highest number of victims. The Coronavirus responsible for COVID-19 has, as its main target organ, the respiratory system, being able to determine a serious acute respiratory syndrome similar to that of the cases found during the SARS epidemic of 2003: hence the name of the virus as SARS-CoV-2. The diagnosis of SARS-COV-2 infection is made by direct detection by PCR of viral RNA on different biological materials from patients with suspicious symptoms, and the first level diagnostic test is generally the nasopharyngeal swab. However, even if the specificity of the nasopharyngeal swab is high, its sensitivity can be affected by technical causes (sampling mode), as well as by intrinsic factors related to the method. The purpose of the study is to identify the clinical, laboratory and imaging characteristic which are similar or which can differentiate the hospitalized patients affected by COVID-19 pneumonia (with positive PCR on naso-pharyngeal swab) and patients with pneumonia with negative PCR for COVID-19. To do this, the investigators will compare the clinical, laboratory and imaging characteristics between interstitial pneumonia secondary to SARS-COV-2 infection, confirmed by molecular biology investigations (viral RNA research by PCR on nasopharyngeal swab) and cases of interstitial pneumonia negative to the nasopharyngeal swab.
The recent pandemic due to the SARS-CoV2 results in a pulmonary infection in major symptomatic patients. Because of the large number of patients and the risk of acute respiratory distress syndrome (which seems to occur in almost 5% of patients), there is a real challenge to improve physician ability to screen between patients those who will require specific surveillance and those who can be sent back home. The recent French official recommendation of the French radiology society prescribe that chest X-ray do not have any place in the COVID-19+ management whereas the WHO stipulate that ultrasound machines may be useful for these patients [1-2]. Moreover, scattered recent publications tend to stress the interest of quick ultrasound imaging for COVID-19 suspected patients for screening purpose [2-5]. The aim of this observational historico-prospective study is to assess the risk of severe clinical outcomes (admission in continuous care unit (USC), invasive respiratory assistance, death) in patients suspected or diagnosed COVID-19+ as a function of initial pulmonary ultrasound abnormalities. These clinical outcomes are assessed through phone calls at D5, D15, M1. The secondary objectives are: - Assessing the concordance between the severity of pulmonary lesions as detected by pulmonary ultrasound devices and the ones detected by CT-scanner, for patients who will undergo these two examinations. - Assessing the compared performances in detecting ultrasound pulmonary lesions for patients suspected or diagnosed COVID-19+, between an experimented operator and a newly trained operator. - Evaluate in suspected or COVID-19 patients, the risk of clinical worsening based on pulmonary ultrasound abnormalities during follow-up of hospitalized patients. - Evaluate the ultrasound evolution profiles of pulmonary lesions in patients whose clinical evolution is favorable. - Evaluate the incidence of thromboembolic events in patients who worsen secondarily.
After randomization, the subjects undergo flexible bronchoscopy either with fractionated propofol administration or with propofol-TCI. Measurement of blood pressure, heart rate, oxygen saturation, and oxygen requirement are measured continuously during the procedure and thereafter. Cumulative propofol dose, and induction, procedure, and recovery time are noted continuously during and after the procedure.
This study will examine the course of patients with progressive rheumatoid arthritis associated interstitial lung disease (RA-ILD) treated with rituximab for safety and progression-free survival at 48 weeks. Safety of rituximab therapy in this disease will be assessed through patient history, physical exams and laboratory parameters. - Twelve male/or female patient with RA-associated lung disease (6 of each nonspecific interstitial pneumonia (NSIP) and usual interstitial pneumonia (UIP) histological subtype) will be enrolled - The study involves 12 visits over 48 weeks - Rituximab will be administered intravenously at Day 1 and Day 15 with repeat dosing at six months.
