Purpose: To perform a semiquantitative and quantitative analysis of interstitial lung disease (ILD), through computed tomography (CT), in different serological subgroups of idiopathic inflammatory myopathies (IIM) patients, to find radiologic and clinical differences of disease related to serology.

Materials And Methods: This was a prospective study, which included 98 IIM patients, divided into serological subgroups: anti-aminoacyl-transfer-RNA-synthetases (anti-ARS) positive and myositis-specific autoantibodies (MSA) negative.For each baseline CT the total semiquantitative score of Warrick (WS) and the automated software (Computer-Aided Lung Informatics for Pathology Evaluation and Rating) quantitative scores interstitial lung disease % (ILD%) and vascular-related structure % (VRS%) were calculated. Pulmonary function tests included total lung capacity % (TLC%), forced vital capacity % (FVC%), and diffusing capacity of the lung for carbon monoxide % (DLCO%).

Results: Inverse correlations ( P <0.001) between the radiologic scores and the functional scores DLCO% and TLC% were found, the most relevant being between ILD% and DLCO% (ρ=-0.590), VRS% and DLCO% (ρ=-0.549), and WS and DLCO% (ρ=-0.471).Positive correlations between ILD% and VRS% (ρ=0.916; P <0.001), WS and ILD% (ρ=0.663; ρ<0.001), and WS and VRS% (ρ=0.637; P <0.001) were obtained.Statistically significant higher values of WS, ILD%, and VRS% were found in the anti-ARS group (WS=15; ILD%=11; VRS%=3.5) compared with the MSA negative one (WS=2.5; ILD%=0.84; VRS%=2.2).The nonspecific interstitial pneumonia pattern was dominant. No statistically significant differences emerged at pulmonary function tests.

Conclusions: In this study, ILD in anti-ARS-positive and MSA-negative groups was defined through semiquantitative and quantitative analysis of lung CT. The inverse correlations between the radiologic scores and TLC% and DLCO% ( P <0.001) confirm the role of lung CT in the evaluation of ILD in IIM.

Osimertinib, a third-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), has revolutionized one of the standard most efficient treatments for EGFR mutation-positive non-small cell lung cancer (NSCLC). Osimertinib, a third-generation EGFR-TKI, is currently one of most efficient treatments in clinical practice. However, it has a potentially fatal side effect: interstitial lung disease (ILD).

Introduction: In response to the SARS-CoV-2 pandemic in March 2020 and required adherence to infection control measures and patient and staff safety, an integrated respiratory team (IRT) developed guideline-based templates to support the team in teleconsultation reviews of their patients. Patients had been diagnosed with sleep disordered breathing, chronic obstructive pulmonary disease, asthma, interstitial lung disease or had oxygen assessment needs.

Methods: Nine IRT members collaboratively developed content for the templates to assist in clinical reviews.

Low-dose methotrexate in Rheumatology: A reinvented drug.

Low-dose methotrexate (LD-MTX) is the anchor drug used in the treatment of various rheumatological illnesses. There are a lot of misconceptions associated with the long-term use of MTX in the minds of practitioners. The origin of most of these myths stems from the ill effects associated with high-dose MTX used in cancer chemotherapy.

Background: Clinically amyopathic dermatomyositis (CADM) is a rare subtype of idiopathic inflammatory myositis often linked with the presence of autoantibodies targeting melanoma differentiation-associated protein 5 (MDA5). Patients with CADM are at increased risk of developing rapidly progressing interstitial lung disease, which significantly increases both morbidity and mortality compared to other forms of inflammatory myopathies. While there is no standardized treatment regimen, current therapeutic strategies are generally focused on combination immunosuppressive therapies.

Unlabelled: Sarcoidosis is a multisystemic syndrome characterized by non-caseous granulomatous inflammation, although necrotizing sarcoid granulomatosis is considered part of the spectrum of the disease. Drug induced sarcoidosis-like reaction (DISR) is a systemic granulomatous reaction, which is histopathologically identical to primary sarcoidosis - mostly described after the use of biologics like tumour necrosis factor alpha antagonists but also anti-CD20 (rituximab). The authors present the very rare case of a woman with a primary Sjögren's syndrome (pSS) started on rituximab for disease control, which evolved with a 3-year indolent progressive systemic sarcoid reaction.
