068. Cyclophosphamide in the Treatment of Severe Interstitial Lung Disease in Patients with Rheumatoid Arthritis
Bibliographic record
Abstract
Background: There is little evidence base to guide clinicians in the management of patients with RA-related interstitial lung disease (ILD). In the subgroup of patients who have rapidly deteriorating respiratory function, pulsed CYC has been advocated but no assessment of its efficacy has been published. The British Rheumatoid Interstitial Lung (BRILL) network has collected data on the treatment and outcomes of 260 patients with RA-ILD, which allow assessment of this therapeutic strategy. Methods: We identified 260 patients across 16 UK centres who met the 2010 EULAR criteria for RA and had confirmation of ILD on high-resolution CT (HRCT) of the lungs. We analysed demography, all drug therapy, duration of disease, subtype and extent of ILD on HRCT, smoking history, serology and baseline pulmonary function. For each patient who had received pulsed i.v. CYC, we identified two case controls with RA-ILD who had never received this drug and who were matched for age, gender, disease subtype and extent. We compared duration of both RA and of ILD between the two groups, as well as vital capacity (VC) and gas transfer [carbon monoxide transfer factor (TLco)]. Mortality and mean survival times in each group were compared.

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.
