Laboratory examination of the patient's serum obtained before therapy revealed various autoantibodies, such as PA-IgG, anti-platelets, anti-single-stranded DNA (ssDNA), and anti-double-stranded DNA (dsDNA) antibodies (Abs) in addition to anti-DRS-1 Abs and anti-moesin Abs, both of which are known to be detectable in approximately 40% of all patients presenting with AA. He was therefore treated with 17.5mg/kg/d rituximab 5.5months after ATG/CsA therapy. The same rituximab therapy was repeated three times once a month thereafter. His neutrophil counts started to increase 50d after the first rituximab therapy and he achieved a complete remission at 16months after the last rituximab administration. All of the autoantibodies including anti-ssDNA, dsDNA, DRS-1, and moesin became undetectable when he attained the remission. Anti-CD20 monoclonal antibody therapy may be effective in a subset of patients with AA characterized by the presence of autoantibodies. © 2011 John Wiley & Sons A/S., 金沢大学医薬保健研究域医学系}, pages = {541--545}, title = {Aplastic anemia successfully treated with rituximab: The possible role of aplastic anemia-associated autoantibodies as a marker for response}, volume = {86}, year = {2011} }
