Abstract
Background:
Colonic graft-versus-host disease (GVHD) is rare in children. The goal of this study was to evaluate the Lerner and the Farooq grade in pediatric patients.
Methods:
Retrospective multicenter study including all biopsies with a diagnosis of GVHD.
Results:
101 patients were included (median age: 8.9 years) with a male predominance (59%). 71% of patients had extracolonic GVHD. 98% and 54% of cases had apoptotic bodies and >6 apoptotic bodies, respectively. Crypt dropout was seen in 53% of cases and ulceration in 19%. Using the Lerner grade, 47% of cases were grade 1, 13% grade 2, 20% grade 3 and 20% grade 4; and using the Farooq grade, 35% were indeterminate for GVHD, 25% low, 27% intermediate and 14% high grade. There was moderate agreement (K = 0.47) between the system. 67% of the Lerner grade 1 cases were considered indeterminate for GVHD using the Farooq grade. No difference was seen with GVHD-related death and the grading systems. GVHD-related death was associated with extraintestinal involvement (P = .04), and with treatment response (P < .01).
Conclusions:
Although neither system was associated with GVHD-related death, given the more comprehensive approach, the authors suggest utilizing the Farooq grading system.
