ABSTRACT

Sinusoidal obstruction syndrome, also known as veno-occlusive disease (SOS/VOD), is a potentially life threatening complication that can develop after hematopoietic cell transplantation. Although SOS/VOD progressively resolves within a few weeks in most patients, the most severe forms result in multi-organ dysfunction and are associated with a high mortality rate (40%). There fore, careful attention must be paid to allow an early detection of SOS/VOD, particularly as drugs have now proven to be effective and licenced for its treatment. Unfortunately, current criteria lack sensitivity and specificity, making early identification and severity assessment of SOS/VOD difficult. The aim of this work is to propose a new definition for diagnosis, and a severity grading system for SOS/VOD in adult patients, on behalf of the European Society for Blood and Marrow Transplantation.
