    Abstract: This invention provides a method for diagnosis of rheumatoid arthritis of a subject, a method for assisting diagnosis of rheumatoid arthritis, and a method for monitoring disease activity of rheumatoid arthritis and/or therapeutic effects of an agent for rheumatoid arthritis, comprising detecting citrullination of an arginine residue of the inter-α-trypsin inhibitor heavy chain (ITIH) 4 in a biological sample obtained from the subject. This invention also provides a citrullinated protein derived from the protein having the amino acid sequence as shown in SEQ ID NO: 1 or 5 by modification of arginine 438 into citrulline or a fragment thereof, an antibody binding to such citrullinated protein, and an agent for diagnosis of rheumatoid arthritis comprising such antibody.
