A 74-year-old Japanese woman with rapidly progressive DM-associated ILD was treated with high-dose glucocorticoids, intravenous cyclophosphamide, and cyclosporine, followed by tofacitinib due to an insufficient response. Discontinuation of tofacitinib alone resulted in rapid clinical and radiological improvement. This case highlights PAP as a rare, potentially reversible complication during JAK inhibitor therapy in anti-MDA5 antibody-positive DM-associated ILD and underscores the importance of considering PAP when elevated KL-6 levels and radiological abnormalities occur despite only mild respiratory symptoms.

The effect of RT (8 and 3 × 8 Gy) on Interferon beta (IFNβ), IFN-stimulated genes (ISGs), and HLA-class-I expression in combination with IFN-type-I-response inhibitors (Ruxolitinib, Tofacitinib, Amlexanox) targeting the JAK and TBK1 was studied with Flow cytometry and RT-PCR. The current study supports the theory that baseline autophagy, RT-induced autophagy blockage, and IFN-type-I response enhancement define the HLA-class-I levels in NSCLC cells. This complex interplay emerges as a promising target for the development of radio-vaccination strategies to enhance the efficacy of radio-immunotherapy.
