COVID-19 in Patients with Pulmonary Hypertension: A National Prospective Cohort Study.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with pulmonary endothelial dysfunction. There are limited data available on the outcomes of coronavirus disease (COVID-19) in patients with pulmonary hypertension (PH), a disease characterized by pulmonary endothelial dysfunction. To describe characteristics and outcomes of patients with precapillary PH and COVID-19.

Association between Leflunomide and Pulmonary Hypertension.

Pulmonary hypertension (PH) has been described in patients treated with leflunomide. To assess the association between leflunomide and PH. We identified incident cases of PH in patients treated with leflunomide from the French PH Registry and through the pharmacoVIGIlAnce in Pulmonary ArTerial Hypertension (VIGIAPATH) program between September 1999 to December 2019.

[Diagnostic delay in bronchopulmonary cancers at the USFR Befelatanana Pneumology, Antananarivo, Madagascar].

The time between clinical symptoms onset and the diagnosis of bronchial cancer should be as short as possible so that it can be managed early and effectively. In Madagascar, this diagnostic delay is unknown. Therefore this study aims to evaluated the diagnostic delay of bronchopulmonary cancers at the the USFR Befelatanana Pneumology, Antananarivo, Madagascar.

[Diffuse infiltrative lung diseases due to allergy and iatrogenic causes].

Iatrogenic and hypersensitivity infiltrative pneumonias comprise 3 distinct entities: extrinsic allergic alveolitis, drug-induced pneumonia and radiation-induced pneumonia. The diagnosis of the latter is usually easy, except for the recently identified postradiation bronchiolitis obliterans organizing pneumonia. Diagnosis of extrinsic allergic alveolitis is based on the association of clinical, radiological, functional, immunological criteria and bronchoalveolar lavage fluid analysis.

[Prevalence of allergy to cockroaches in the African intertropical zone. Review of the literature].

The epidemiology of environmental allergens and their role in respiratory pathology remains poorly understood in sub-Sahara Africa. The aim of this work was to measure the frequency of sensitivity to cockroach allergens of subjects with chronic respiratory affections in the Ivory Coast. We recruited consecutively 140 patients, adults and infants, who had asthma, rhinitis or sinusitis over a period of 20 months, in a hospital environment.

[Respiratory pathology in the agricultural environment].

Farmers are usually exposed to a wide variety of noxious organic or chemical substances. This explains why agriculture is probably one of the occupations where prevalences of respiratory diseases are the highest. Some diseases such as extrinsic allergic alveolitis, allergic asthma, silo filler's disease or pesticides-related fibrosis are classic and well described.
