Extracorporeal membrane oxygenation for acute lung injury in idiopathic inflammatory myopathies—a potential lifesaving intervention
Bibliographic record
Abstract
OBJECTIVES: Idiopathic inflammatory myopathies (IIM) can present with acute IIM-related lung injury and respiratory failure, leading to a high mortality risk in intensive care units (ICU). Extracorporeal membrane oxygenation (ECMO) in acute respiratory distress syndrome can be lifesaving. We aimed to report a case series of IIM patients that received ECMO. METHODS: Patients with IIM from tertiary care centres in Belgium, Canada, Denmark, USA and Sweden who underwent ECMO were reviewed to describe clinical characteristics, disease outcomes and hospitalization course. Clinical characteristics at admission and during ICU stay including ECMO complications and mortality causes were summarized. RESULTS: The study included 22 patients (50% female, mean ± SD age at admission 47 ± 12 years) with anti-MDA5 positive dermatomyositis (68%), anti-synthetase syndrome (14%), polymyositis (9%), overlap myositis (5%) and non-MDA5 dermatomyositis (5%). Patients had low comorbidity scores and 46% had received immunosuppression before their ICU admission. Eight (36%) patients died in the ICU, six (27%) were bridged to recovery and eight (36%) were bridged to transplant. When comparing patients bridged to recovery and those who died in the ICU, those who died were older (P = 0.03) and had higher median Charlson comorbidity index scores (P = 0.05). Both groups had similar frequencies of ECMO-related complications (33% vs 50%, P = 0.94). CONCLUSION: In the patients exposed to ECMO in this case series, 14 were successfully bridged to recovery or transplant, while 8 died in the ICU. Large studies are needed to collect data on clinical outcomes in patients with IIM-ILD exposed to ECMO to identify the best candidates for the intervention.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
