Abstract

Six children with steroid resistant graft versus host disease (GVHD) after hematopoietic stem cell transplantation admitted in the hospital, including 4 cases of acute GVHD and 2 cases of chronic GVHD. Among the 4 acute GVHD cases, the main manifestations were large area rash and fever in 2 cases, and abdominal pain and diarrhea in 2 cases. In 2 chronic GVHD cases, one presented lichenoid dermatosis, and the other showed repeated oral ulcers with difficult mouth opening. Patients received tocilizumab (8 mg/kg per dose every 3 weeks) and ruxolitinib (5-10 mg/d, 28 d), at least 2 courses were completed. All patients had complete responses (100%), and 5 patients responded after completion of two treatment courses, with the median time of remission was 26.7 d. The median follow-up period was 11 (7-25) months, and no severe treatment-related adverse reactions were observed.
