Review Comparative StudyAcute exacerbation of interstitial lung disease after procedures.
Interstitial lung disease (ILD) is a category of diffuse parenchymal lung diseases characterized by inflammation and/or fibrosis. The best characterized ILD is idiopathic pulmonary fibrosis (IPF). Acute exacerbation of IPF is a dreaded occurrence with grim prognosis and suboptimal treatment options. ⋯ This review summarizes the available information on AE-ILD and discusses the procedures reported to cause AE-ILD. We also discuss proposed mechanisms, risk factors, treatment and prognosis. This review should help to inform decision-making about risks versus benefits of procedures that are commonly recommended to diagnose ILD.

ReviewOmalizumab as alternative to chronic use of oral corticosteroids in severe asthma.
Systemic/oral corticosteroids (OCS) have been used for decades in the management of acute asthma exacerbations and chronically in patients with uncontrolled severe asthma. However, while OCS are effective at treating acute exacerbations, there is only empirical evidence regarding the efficacy of OCS at reducing the rate of exacerbations. Evidence, although scarce, is suggestive of high exacerbation rates in severe asthma patients even when receiving maintenance treatment with OCS. ⋯ Anti-IL-5/IL-5R biologics are indicated in patients with severe eosinophilic asthma and repetitive exacerbations, irrespective of the presence or absence of allergy. Recently, an anti-IL4Rα biologic has been approved by the FDA for eosinophilic phenotype or oral corticosteroid-dependent asthma. Finally, physicians should consider using biologics as an alternative to chronic OCS therapy.
