Categories include 1) no improvement, 2) regenerative changes, 3) limited improvement, 4) partial improvement and 5) complete response. Endoscopic manifestations of acute graft-versus-host disease include edema, erythema, mucosal ulceration and denudation. Complete mucosal recovery was defined as the appearance of intact mucosa with at least 98% of the luminal surface covered by epithelium. Partial response was defined as the appearance of mostly intact mucosa with at least 80% improvement or less than 10% denuded. Limited response was retrospectively designated to describe visible improvement that was less than partial response. Regenerative change was retrospectively designated to describe early reappearance of mucosal integrity in a previously denuded area but not sufficient to meet criteria for partial response. Failure to respond was defined as failure to meet partial response criteria.","groups":[{"description":"Patients received oral lithium carbonate once or twice daily.
