1. A method for treating an interstitial pneumonia with autoimmune features (IPAF) patient with anti-inflammatory therapy, comprising:
measuring at least one biomarker in a biological sample of an IPAF patient, wherein the biomarker is CXCL9;
comparing a measured value of CXCL9 with a predetermined threshold value;
determining that the patient may be responsive to an anti-inflammatory treatment based on a result of the comparing step, wherein the result comprises the measured value of CXCL9 being greater than or equal to a predetermined threshold value; and
treating the patient with the anti-inflammatory therapy based on the result of the comparing step, wherein the result comprises the measured value of CXCL9 being greater than or equal to the predetermined threshold value.
