Clinicopathological features of patients with acute graft-versus-host disease of the upper digestive tract.

Abstract：

BACKGROUND AND AIMS:Acute graft-versus-host disease (GVHD) occurring within 100 days post-transplant is one of critical factors influencing prognosis in transplant recipients. Among cases of GVHD of the gastrointestinal (GI) tract, GVHD rarely affects the upper GI. In this study, we retrospectively examined the frequency of upper GI GVHD and diagnostic accuracy. PATIENTS AND METHODS:From among 868 patients who underwent allogeneic hematopoietic stem cell transplantation at our hospital between January 2005 and June 2012, 115 of whom underwent biopsy for upper GI symptoms. The endoscopic findings and histologic diagnosis from these 115 patients were retrospectively analyzed. RESULTS:GVHD was histologically diagnosed in 85 patients overall (9.8% of all 868 transplant recipients). Although gastric mucosal exfoliation was not commonly observed, this endoscopic finding when used as a diagnostic predictor had both a specificity and positive predictive value (PPV) of 100%. When using redness, luster, and mucosal change as predictors, specificity and PPV were relatively high, suggesting that these gastric endoscopic findings are useful in the diagnosis of upper GI GVHD. Among the duodenal endoscopic findings, erosion as a diagnostic predictor had both a high specificity and PPV. The biopsy results often lead to a diagnosis of GVHD even in cases judged to be endoscopically normal. CONCLUSIONS:Among the gastric endoscopic findings, mucosal exfoliation, although rare, and redness, luster, and mucosal change are likely to be useful diagnostic predictors of upper GI GVHD. GVHD was frequently diagnosed in patients with endoscopically normal duodenum, suggesting that biopsies are important for definitive diagnosis.
