Abstract

fetched live from OpenAlex

Extracorporeal photopheresis (ECP) for chronic lung allograft dysfunction (CLAD) has been reported as beneficial in a few short-term studies. In this retrospective study we report results obtained on 48 CLAD patients treated by off-line ECP for a long time (>8 years) (compared to 58 historical controls) and we explore potential predictors of survival and response. ECP patients, enrolled between February 2003 and December 2013; were n 14 RAS and 34 BOS (grade 1: 58.3%%, grade 2: 20.8%, grade 3: 20.8%), median follow-up was 65 months (cumulative 2284.4 persons-months). Deaths were 20 (41.7%), of which 17 (85%) CLAD-related. Among controls, deaths were 42 (72.4%), of which 32 (76.2%) CLAD-related, over a median 51 months (cumulative 3066.5) (p=0.09). Mortality rate according to failure at 6 months from baseline was significantly higher for historical controls with failure (p<.001) than for all other patient groups including ECP failures. Among ECP patients, FEV1 slope flattened out after the initial months decline (slope -19 ml/month in months 0-6, +4 in months 36-48 and later, p=0.001). RAS was associated to poorer survival, but a pattern of more rapid decline in the previous 6 months was not. No ECP side effects or complications with the off line technique were observed. Long-term ECP treatment for CLAD is safe and reduces FEV1 decline over time also with off line technique; it deserves to be evaluated in a randomized controlled trials, as first line therapy .

Not 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.
