The long-term goal of our research is to accurately identify SOS patients who would benefit from defibrotide treatment using US SWE. The overall objective of this study is to validate SWE as an early diagnostic marker for SOS. Our central hypothesis is that SWE changes will precede clinical and conventional US diagnostic criteria for SOS. Our hypothesis has been formulated on the basis of our own preliminary data. The investigators completed the first prospective cohort trial demonstrating that US SWE provides SOS diagnosis (80% sensitivity and 67% specificity) nine days earlier than current clinical criteria. SWE is widely available, has no known side effects, and is easy to learn and interpret. Our study enrolled 25 high-risk BMT patients over 18 months (five with SOS and two with severe SOS). More data is needed to determine the optimal window for testing to balance between improved test characteristics and early detection of disease. The investigators propose conducting a prospective cohort study with 80 additional patients, 12 of which will likely develop SOS (including four with severe SOS) to optimize SWE timing. This study will increase the confidence in the findings from our preliminary study and allow us to test SWE against newly published clinical criteria. The rationale for the proposed research is that, if SWE can diagnose SOS earlier than clinical criteria, then SWE can guide early initiation of SOS treatment.
ELASTOVOD is a prospective multicenter study, involving several centers of Onco-haematology in Italy. Investigators perform hepatic elastographic measurements (with Transient Elastography, ARFI or 2D-SWE) on patients undergoing HSCT, at baseline before transplantation (T0) and at T1/T2/T3 after HSCT (+9/10, +15/17, +22/24). SOS/VOD diagnosis was performed according to clinical criteria.
The goal of this is to learn more about stem cell transplant and complications that some people have after their transplants, in particular sinusoidal obstruction syndrome (SOS), also called veno-occlusive disease of the liver.
Sinusoidal obstruction syndrome (SOS) is a potentially fatal hepatic veno-occlusive disease-affecting children following bone marrow transplantation (BMT). SOS most likely develops secondary to sinusoidal endothelial damage and subsequent obstruction. The disease can be separated into mild, moderate, and severe forms; almost all patients diagnosed with severe SOS will die from this disease. Children with severe SOS suffer from multi-organ failure with signs and symptoms of portal hypertension (ascites, varices, edema), renal and respiratory failure . Although these children may be few and far between, the mere severity of the disease process and awful prognosis factors are valid reasons for more medical attention. SOS is usually diagnosed via clinical criteria and, despite available prophylaxis and treatment, children continue to die from this devastating disease. Quantitative shear wave ultrasound elastography with acoustic force radiation imaging is an emerging technology that uses ultrasound pressure waves to provide an estimate of tissue stiffness. This technique is promising for pediatric imaging because it is portable, quick to perform, relatively low cost and involves no ionizing radiation. Acoustic force radiation imaging and ultrasound elastography does not have any increased risks over conventional ultrasound imaging.
The purpose of the study is to determine whether anticoagulant use (i.e. salicylates, clopidogrel, low-molecular weight heparin, or coumarin derivates) is able to prevent the development of the sinusoidal obstruction syndrome secondary to oxaliplatin-based neoadjuvant chemotherapy in patients suffering from colorectal liver metastases.
