We report the case of a 45-year-old man who was diagnosed with clinically amyopathic dermamyositis (CADM) and interstitial lung disease (ILD) after presenting with skin lesions typical of CADM and testing positive for anti-Melanoma Diferentiation-Associated gene 5 (anti-MDA5) anti-bodies. He was treated with a regimen including steroid pulse therapy, intravenous cyclophosphamide (IVCY), and calcineurin Inhibitor drug, which initially improved his ILD. However, three months post-treatment, the first deterioration of his conditions occurred, necessitating further administration of steroid pulse therapy and IVCY. After eight cycles of IVCY therapy, the serum levels of KL-6 and anti-MDA5 antibodies decreased, and reaching their lowest values. Nevertheless, two years and six months after the first observed deterioration, the second deterioration of his conditions occurred, leading to acute respiratory failure, treated again with steroid pulse therapy and IVCY. This treatment did not result in improvement of respiratory failure, therefore plasma exchange was attempted, which demonstrated a beneficial effect on the ILD for a short time. This case suggests that IVCY and plasma exchange might be effective therapeutic options for CADM with ILD.

Background and Aims: Bronchial thermoplasty (BT) is a bronchoscopic treatment for adult patients with moderate to severe asthma. A systematic review was conducted to examine the efficacy of this treatment.

Methods: Randomized controlled comparing BT to a control in adult patients with moderate to severe asthma were added to the previously conducted systematic review. Literature published prior to July 2022 was selected.

Results: Four trials were included in this study. BT resulted in significant improvement in quality of life. However, no significant difference in asthma control was observed. Moreover, the incidence of severe adverse events during the treatment period was increased by BT. Furthermore, BT did not improve lung function, increase withdrawal from oral corticosteroids, reduce frequency of rescue medication usage, or increase the number of symptom-free days.

Conclusion: From a risk-benefit perspective, there is insufficient evidence to support a recommendation of BT in adult patients with moderate to severe asthma.
