1. A method for identifying and treating idiopathic pneumonia syndrome (IPS) progression in a subject following allogeneic hematopoietic stem cell transplantation, the method comprising:
obtaining a biological sample from the subject, wherein the biological sample comprises a sample of blood, plasma, serum, or bronchoalveolar lavage fluid, wherein the subject has received the allogeneic hematopoietic stem cell transplantation;
determining in the biological sample a level of PGLYRP2;
comparing the determined level of PGLYRP2 to a control level prior to transplantation;
identifying the IPS as progressing if the level of PGLYRP2 determined is decreased at least 5% compared to the control level; and
administering a therapeutically effective amount at least one TNF-α inhibitor to the subject with progressive IPS.
