Abstract:
BACKGROUND:Hepatic sinusoidal obstruction syndrome (SOS) is a serious complication of autologous stem cell transplant (ASCT) in children with historically high mortality rates. Defibrotide has shown proven benefit in its treatment and may have a modest role in prevention. We report our experience with SOS in children undergoing autologous transplant. METHODS:Case records of 82 consecutive patients undergoing ASCT following high-dose chemotherapy between 2010 and 2017 were reviewed. Defibrotide was used for treatment of all with SOS and prophylactically in patients receiving busulfan-based conditioning until 2014. RESULTS:Fourteen of the 82 children (17%) were diagnosed with SOS. The incidence was higher in those receiving busulfan-based conditioning (13/42 vs 1/40, P = 0.008). Mean (±SD) time to diagnosis of SOS was 19 (±5.6) days following stem cell rescue. Bilirubin levels and ultrasound were normal in 7/14 and 3/14 patients. Coagulopathy was noted in 10/14; one child developed multiorgan involvement. Nine children had mild SOS, whereas two and three had moderate and severe SOS, respectively. Intensive care was required for four of five non-mild cases. Patients with SOS had significantly delayed platelet recovery, higher transfusion requirement, and longer hospital stay. Unavailability of defibrotide prophylaxis for 17/42 receiving busulfan did not change the incidence of SOS (7/25 with defibrotide vs 6 /17 without defibrotide, P = 0.74). There was no significant difference in the severity of SOS between these groups. CONCLUSION:Hepatic SOS was more commonly seen in children receiving busulfan-based conditioning. Stopping the use of prophylactic defibrotide did not increase incidence or severity of SOS. Overall outcome was excellent with supportive care and timely treatment with defibrotide.
