Airway-centered fibroelastosis is characterized by peribronchovascular fibroelastosis, predominantly in the upper lobes, with little-to-no pleural involvement. In this study, we describe two cases of airway-centered fibroelastosis diagnosed based on radiological and pathological findings. The first case comprised a 44-year-old man whose forced vital capacity improved over three months following treatment with nintedanib. The second case involved a 50-year-old woman who was treated with oral corticosteroids but yielded an unfavorable outcome. An effective treatment for airway-centered fibroelastosis has not yet been identified; therefore, this study may help contribute to a more thorough discussion regarding treatment strategies for this disease.

A 32-year-old man who had worked as a welder for 13 years was hospitalized for a fever and hemosputum with dyspnea. He was diagnosed with welding fume-associated lung disease with alveolar hemorrhaging and acute respiratory failure. Despite surviving the acute phase with corticosteroid therapy, hypoxemia persisted after a month and a half, requiring home oxygen therapy. As a result of the introduction of nintedanib, his clinical findings gradually improved, and the patient was weaned from oxygen therapy after six months. Inhalation of a large amount of welding fumes in a short period can cause alveolar hemorrhaging and prolonged pulmonary dysfunction.

We describe three cases of acute exacerbation of interstitial lung diseases (ILDs) in which patients were treated with pulsed-doses of corticosteroids followed by nintedanib and maintenance doses of corticosteroids. All cases responded well to pulsed-dose corticosteroids. However, in conventional practice, corticosteroids can complicate adverse events, including opportunistic infections, diabetes, and osteoporosis. One of the cases reported here involved dermatomyositis-associated ILD with anti-EJ antibodies. Considering possible side effects of corticosteroids and the frequent recurrence of ILDs associated with anti-EJ antibodies, we decided to use nintedanib as a sequential treatment for acute exacerbation of ILDs. Nintedanib has just been approved for treatment of progressive fibrosing ILD, but to date, few reports of acute exacerbation of ILDs treated with nintedanib have been published. This case series may contribute to a more thorough discussion regarding the use and timing of nintedanib in treating acute exacerbation of ILDs.

We describe a case of fulminant onset, rapidly progressive-interstitial lung disease (RP-ILD) with anti-ARS antibodies (anti-PL-7). The patient was successfully treated with nintedanib in addition to intensive immunosuppressive therapies, including intravenous cyclophosphamide. Nintedanib has just been approved for treatment of progressive fibrosing ILD, but to date, no reports of RP-ILD treated with nintedanib have been published. This case report may advance discussions regarding the use and timing of nintedanib in treating RP-ILD.
