[Pulmonology 2021: year in review].

Among the new therapeutic developments in pulmonology during 2021, we have identified three topics of interest. A new biotherapy is now available for the management of severe uncontrolled non-Th2 asthma. In the field of pulmonary arterial hypertension, upfront triple therapy at the time of diagnosis is associated with a survival benefit in high-risk patients. Riociguat is a therapeutic option for patients that remain at intermediate risk despite treatment with iPDE5. Sotatercept, a promising new class of drug for treatment of group 1 PAH will soon be available. Finally, the use of transbronchial cryobiopsies as a valid alternative to surgical lung biopsy for the diagnosis of diffuse interstitial lung diseases will also be discussed in this review.
