Using Ultrasound Elastography to Predict Development of SOS
A study testing shear wave ultrasound elastography in people with Sinusoidal Obstruction Syndrome and Complications of Bone Marrow Transplant, run by Children's Mercy Hospital Kansas City at 1 site in United States.
Trial summary
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. Read more about this study

About this study
Official title: Using Ultrasound Elastography to Predict Development of Sinusoidal Obstruction Syndrome
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.
Read the detailed description
This is a single site prospective cohort study that will compare ultrasound elastography to traditional ultrasound parameters in bone marrow transplant patients who are at risk for development of SOS.
- Primary objective: compare sensitivity and specificity of traditional ultrasound parameters and ultrasound elastography of the liver for detecting SOS in BMT patients.
- Secondary objectives: 1. compare sensitivity and specificity of traditional ultrasound parameters and ultrasound elastography of the liver for classifying SOS in BMT patients. 2. compare sensitivity and specificity of traditional ultrasound parameters and ultrasound elastography of the liver for predicting death in BMT patients with SOS (defined as death within 100 days of transplant).
- The validity and reliability of the primary and secondary measures when available. The validity of the measures will be determined by comparing to clinical gold standards of the diagnosis and classification of SOS
Data Collection Procedures
- Candidates for the study will be identified by the Hematology Oncology service when they are admitted for bone marrow transplant.
- A member of the study team will consent that patient and/or their parents once the patient has been identified.
- If the patient consents to the study, an initial limited abdominal ultrasound with Doppler and shear wave elastography will be performed less than one month prior to bone marrow transplant. Demographic and clinical variables will be collected from the chart at the time of initial ultrasound and after date of discharge. Lab value variables will be collected at the time of the initial ultrasound and during all subsequent ultrasounds. Only lab values that have changed since the prior ultrasound will be recorded.
- Multiple shear wave elastography measurements of the liver will be obtained during any post-transplant clinical abdominal ultrasound Data Analyses We will perform two-sided t-tests and nonparametric tests for categorical and continuous data, respectively. Additionally, we will perform a multivariate regression to determine which variables are significantly correlated to death and calculate an odds ratio for each of these variables. If a patient is missing any imaging or clinical data, then this patient will be excluded from those parts of the data analysis, but the rest of their data will still be included in the study.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
A study testing shear wave ultrasound elastography in people with Sinusoidal Obstruction Syndrome and Complications of Bone Marrow Transplant, run by Children's Mercy Hospital Kansas City at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 14 Feb 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sensitivity and Specificity of US for VOD/SOS (time frame: within 100 days of bone marrow transplant). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02483481, which also lists 20 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Feb 2024.
