A systematic literature review of the clinical signs and symptoms of veno-occlusive disease/sinusoidal obstruction syndrome after haematopoietic cell transplantation in adults and children.

ABSTRACT: Veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is a rare, serious complication following haematopoietic cell transplantation (HCT). This systematic literature review evaluated differences in clinical manifestations of VOD/SOS post-HCT in adults and children. Medline and Embase were searched up to 4 March 2021 for reports of VOD/SOS post-HCT; VOD/SOS diagnostic guidelines were included. Publications were evaluated based on inclusion of five cardinal clinical features of VOD/SOS (ascites, hepatomegaly, hyperbilirubinaemia, right upper quadrant [RUQ] pain and weight gain ≥5%). Overall, 204 publications were included. At diagnosis, hyperbilirubinaemia was more common in adults (93%) versus children (82%), weight gain ≥5% and hepatomegaly were more common in children (86%, 89%) versus adults (73%, 76%) and ascites and RUQ pain were similar between age groups. While 40% of cases had all five cardinal features, age was not a substantial determinant of the likelihood of missing any single specific feature. The proportion of cases, where hyperbilirubinaemia was the first recorded feature, was higher in children versus adults; weight gain and RUQ pain appeared first in a greater proportion of adults versus children. VOD/SOS diagnosis can be challenging; features may not present in a distinct sequence. This necessitates continuous vigilance by those involved in patient monitoring post-HCT.

Project description:BackgroundSinusoidal obstruction syndrome is a potentially fatal complication following hematopoietic cell transplantation, high-intensity chemotherapies and increasingly seen with calicheamicin based leukemia therapies. Paediatric specific European Society for Blood and Marrow Transplantation (pEBMT) diagnostic criteria have demonstrated benefit in single center studies compared to historic criteria. Yet, the extent to which they have been universally implemented remains unclear.MethodsWe conducted a retrospective multi-centre study to examine the potential impact of the Baltimore, modified Seattle and pEBMT criteria on the incidence, severity, and outcomes of sinusoidal obstruction syndrome among paediatric hematopoietic cell transplantation patients.FindingsThe incidence of sinusoidal obstruction syndrome in this cohort (n = 488) was higher by pEBMT (21.5%) vs historic modified Seattle (15.6%) and Baltimore (7.0%) criteria (p < 0.001). Application of pEBMT criteria identified 44 patients who were not previously diagnosed with sinusoidal obstruction syndrome. Overall, 70.5% of all patients diagnosed with sinusoidal obstruction syndrome ultimately developed very severe disease and almost half of diagnosed patients required critical care support. Overall survival was significantly lower in patients who were diagnosed with sinusoidal obstruction syndrome vs those who were not.InterpretationTaken together, pEBMT criteria may be a sensitive method for prompter diagnosis of patients who subsequently develop severe/very severe sinusoidal obstruction syndrome. To our knowledge, this is the first multi-centre study in the United States (US) to demonstrate that pEBMT guidelines are associated with earlier detection of sinusoidal obstruction syndrome. Since early initiation of definitive treatment for sinusoidal obstruction syndrome has been associated with improved survival in paediatric patients and implementation of pEBMT criteria appears feasible in the US, universal adoption should facilitate prompter diagnosis and lead to improved outcomes of children with sinusoidal obstruction syndrome.FundingNone.

Project description:Veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is a potentially life-threatening complication of hematopoietic cell transplantation (HCT) that is traditionally diagnosed using Baltimore or modified Seattle criteria. Whereas the Baltimore criteria require the presence of hyperbilirubinemia (bilirubin ≥2 mg/dL) for a diagnosis of VOD/SOS, the modified Seattle criteria do not. Before approval by the US Food and Drug Administration, defibrotide was available in the United States through an expanded-access study (T-IND). The T-IND protocol initially required post-HCT diagnosis of VOD/SOS by the Baltimore criteria or biopsy but was later amended to include patients diagnosed using the modified Seattle criteria. This post hoc analysis examined the incidence of VOD/SOS with a bilirubin level <2 mg/dL before and after Day 21 post-HCT in T-IND patients enrolled following the amendment allowing for diagnosis by the modified Seattle criteria. Survival of adult and pediatric patients with or without hyperbilirubinemia and with or without multiorgan dysfunction (MOD) was also evaluated. Of 803 post-HCT patients with VOD/SOS enrolled following the protocol amendment, 181 (23%) had a bilirubin level <2 mg/dL and would not have been diagnosed if hyperbilirubinemia was required. The bilirubin level at diagnosis was <2 mg/dL in 165 of 331 patients (50%) diagnosed by the modified Seattle criteria and in 16 of 23 patients (70%) diagnosed by biopsy. VOD/SOS with a bilirubin level <2 mg/dL was more common in pediatric patients (29%), although it also occurred in adult patients (15%). Patients with hyperbilirubinemia had lower Day 100 survival (54% versus 87% in patients with bilirubin <2 mg/dL) and a higher incidence of MOD (41% versus 26% in patients with bilirubin <2 mg/dL). The incidence of treatment-emergent adverse events and serious adverse events was lower in patients with a bilirubin level <2 mg/dL. These results indicate that anicteric VOD/SOS occurs in both adult and pediatric patients post-HCT and can be diagnosed before and after Day 21 in both groups. The worse survival in patients with bilirubin ≥2 mg/dL suggests that requiring hyperbilirubinemia may result in a progressed disease stage associated with worse outcomes. Taken together, these results highlight the importance of awareness and the possibility of VOD/SOS in the absence of elevated bilirubin level.

Project description:Hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is a potentially life-threatening complication that occurs after hematopoietic cell transplantation (HCT). The mortality associated with untreated VOD/SOS with multiorgan dysfunction (MOD) has been reported to be >80%. The recommended dose of defibrotide is 6.25 mg/kg every 6 hours, administered as a 2-hour i.v. infusion, for a minimum of 21 days or until resolution of VOD/SOS signs and symptoms. The objective of this analysis was to evaluate the time to complete response (CR) in patients with post-HCT VOD/SOS treated with defibrotide. The time to defibrotide discontinuation due to a CR served as a surrogate for time to CR in an expanded access study (T-IND; ClinicalTrials.gov NCT00628498; n = 1000), and was analyzed separately from the time to CR data pooled from a phase 2 randomized dose-finding study (NCT00003966; n = 74 patients who received 25 mg/kg/day) and a phase 3 historically controlled study (NCT00358501; n = 102). For all studies, a CR was defined as total serum bilirubin <2 mg/dL with resolution of VOD/SOS-related MOD (renal and/or pulmonary dysfunction); the phase 2 study also required resolution of central nervous system dysfunction. In the T-IND, 390 patients discontinued treatment due to a CR and had sufficient data for analysis. The median time to discontinuation was 22 days (range, 2 to 64 days). Discontinuation due to CR occurred beyond 21 days in 235 patients (60%) and beyond 28 days in 57 patients (15%). The pooled phase 2 and 3 studies included 60 patients who achieved a CR, with a median time to CR of 24.5 days (range, 7 to 123 days). A CR was achieved beyond 21 days in 32 patients (53%) and beyond 28 days in 24 patients (40%). The Kaplan-Meier estimate of day +100 survival rate was substantially higher in patients who discontinued due to a CR compared with those who did not (92.5% versus 37.3%). Treatment-emergent adverse events occurred in 185 of 390 patients (47%) who discontinued due to a CR in the T-IND and in 55 of 60 patients (92%) who achieved a CR in the pooled phase 2 and 3 studies, and rates did not differ according to duration of treatment (≤21 days versus >21 days). Taken together, these results highlight the importance of continued defibrotide therapy until resolution of VOD/SOS signs and symptoms, as currently indicated in the approved product labels, which may occur beyond the recommended minimum of 21 days.
