DETERMINING RESPONSIVENESS OF AUTOIMMUNE PATIENTS TO DMARD TREATMENT

摘要

The invention is directed to a method of screening patients suffering from an autoimmune disease for responsiveness to treatment with a disease modifying anti-rheumatic drug, or DMARD. In some embodiments the method of the invention comprises the steps of (a) measuring an IgH clonotype profile from B-cells in a sample of tissue affected by the autoimmune disease, the IgH clonotype profile including IgH clonotypes, IgG clonotypes, and IgD clonotypes; and (b) classifying a patient as being more likely to respond to DMARD treatment, whenever the patient has, with respect to reference levels characteristic of normal tissue, elevated IgH concentration, elevated IgG fraction, and reduced IgD fraction.

1. A method of screening patients suffering from an autoimmune disease for responsiveness to treatment with a disease modifying anti-rheumatic drug (DMARD), the method comprising the steps of:
determining an IgH clonotype profile from B-cells in a sample of tissue affected by the autoimmune disease, the IgH clonotype profile including IgH clonotypes, IgG clonotypes, and IgD clonotypes; and classifying a patient as being more likely to respond to DMARD treatment, whenever the patient has, with respect to reference levels characteristic of normal tissue, elevated IgH concentration, elevated IgG fraction, and reduced IgD fraction.
