Mesenchymal stromal stem cell therapy in advanced interstitial lung disease - Anaphylaxis and short-term follow-up.

There are limited treatment options for advanced interstitial lung disease (ILD). We describe a patient of ILD treated with mesenchymal stromal stem cell infusion. The index patient had end-stage ILD due to a combination of insults including treatment with radiotherapy and a tyrosine kinase inhibitor Erlotinib. He was oxygen-dependent and this was hampering his quality of life. He tolerated the first infusion stem cells without any problem. During the second infusion he developed anaphylactic shock, which was appropriately managed. At 6-months follow-up he had no improvement in oxygenation, pulmonary function or CT scan parameters. In view of anaphylaxis, further infusions of MSC were withheld. A longer follow-up may reveal long-term benefits or side effects, if any. However the occurrence of anaphylaxis is of concern suggesting that further trials should be conducted with intensive monitoring.
