Early recognition of gastrointestinal graft-versus-host disease (GI GVHD) after allogeneic hematopoietic stem cell transplantation (alloHSCT) is vital to initiation of therapy. However, the most common location, the small bowel (SB), is difficult to access with upper and lower endoscopy (UGE/LGE). Wireless capsule endoscopy (WCE) is a noninvasive technology allowing complete SB evaluation. The capsule location can also be tracked to identify motility derangements. From August 2006 to July 2007, 11 alloHSCT patients with GI symptoms underwent WCE, and visual grading was performed. UGE and LGE with biopsies were done when clinically indicated. All patients had evidence of probable acute GVHD (aGVHD) on WCE. WCE revealed lesions of greater severity than those seen by UGE or LGE in most patients. WCE demonstrated that 45% of patients had delayed gastric transit time. WCE is an excellent, noninvasive method for assessing GI GVHD, with the ability to more accurately assess the severity of GVHD, evaluate clinical symptoms, and follow response to treatment.

Treatment of severe acute and chronic gastrointestinal (GI) graft-versus-host disease (GVHD) with prolonged high-dose systemic corticosteroids has limited success and considerable toxicity. Beclomethasone dipropionate (BDP) is a potent topically active steroid. We treated 15 patients with acute (n = 2) or chronic (n = 13) GI GVHD refractory to systemic corticosteroids with 28-day courses of oral BDP (2 mg 4 times daily). Response was measured by the change in GI score (sum of 6 GI symptoms) as well as the ability to taper or discontinue systemic corticosteroids. Nine (60%) of 15 evaluable patients responded to BDP, including 3 complete responses (a GI score of 0 or 1 and discontinuation of systemic corticosteroids). Attempts to taper calcineurin inhibitor during BDP therapy were unsuccessful. The 2 patients with acute GVHD had no response to BDP. Responders received a median of 3 cycles (range, 1-20), compared with 1 cycle (range, 1-5) in nonresponders. Suppression of the hypothalamic-adrenal axis was seen in 2 of the 5 patients tested, but neither demonstrated clinically significant symptoms. We conclude that BDP is safe and effective for long-term treatment of chronic GI GVHD. Multiple courses may be necessary to achieve or maintain response in some patients, and prolonged BDP therapy is a feasible alternative to prolonged systemic corticosteroids.

Gastrointestinal zygomycosis is a rare condition with a high mortality rate. We present 2 fatal cases of hepatic zygomycosis following allogeneic hematopoietic stem cell transplantation and review the literature. [ABSTRACT FROM AUTHOR]
