Liver and the Spleen Stifness in Adult Patients With Gaucher's Disease Using Ultrasound Shear Wave Elastography

Terminated

• Conditions: Gaucher Disease; Liver Fibrosis; Spleen; Fibrosis

• Registration Number: NCT03896607
• Lead Sponsor: HaEmek Medical Center, Israel

Brief Summary

The investigated cohort will examine liver and spleen fibrosis in patients with Gaucher Disease(GD) by using Shear Wave Elastography- SWE to evaluation fibrosis of the tissue and to check the correlation of fibrosis with the biomarkers of disease severity.

Detailed Description

To assess liver and spleen stiffness measurement using Shear Wave Elastography-SWE and evaluate liver and spleen fibrosis in patients with Gaucher Disease. To compare the elastography with the biomarkers that taken at the GD haematology clinic and to check the correlation with severity of liver and spleen fibrosis.

SWE is a safe with diagnostic accuracy regarding the liver (\& Spleen) fibrosis. Estimating spleen fibrosis is an innovative approach in liver disease and Gaucher.

The evaluation of fibrosis with this relatively new and safe method could avoid complications and invasive procedure in GD patients .

Primary Outcome Measures

Name	Time	Method
Shear Wave Elastography of liver to asses liver fibrosis in Gaucher disease patients.	0-2 hours	Shear wave elastography(SWE),an ultrasound imaging technique that can produce 2D and 3D images and quantified measurements of tissue stiffness noninvasively. SWE obtained from the right liver lobe for staging liver fibrosis according to Metavir Fibrosis Score with sensitivity86%-98% and specificity 90%-93%. SWE well corelated with Metavir Fibrosis Score which is system used to assess the extent of inflammation and fibrosis by histopathological evaluation in a liver biopsy. The biomarkers of disease severity will be correlated to METAVIR score. METAVIR score(F0-F4) ,Fibrosis Level measured by KPa(kiloPascal) using SWE. F0 = Below 5 KPa, No fibrosis. F1=5.0-7.1 KPa, Mild Fibrosis. F2=7.1-8.7 KPa, Significant Fibrosis. F3=8.7-10.4 KPa, Sever Fibrosis. F4=10.4-19 KPa ,Cirrhosis. SWE can differentiate patients with no or minimal (F0 and F1) fibrosis from those with severe fibrosis or cirrhosis (F3 and F4) with no need for biopsy unless there are other factors that need to be considered.

Secondary Outcome Measures

Name	Time	Method
Shear Wave Elastography of spleen to asses spleen fibrosis in Gaucher disease patients.	0-2 hours	Shear wave elastography (SWE), an ultrasound imaging technique that can produce 2D and 3D images and quantified measurements of tissue stiffness noninvasively.; Participants with Gaucher disease will under go shear wave elastography for spleen.; Ultrasound Elastography is a non-invasive test which uses the technology of Shear Wave Elastography (SWE) obtained from the spleen for staging tissue fibrosis according to a study, Spleen Elastography was performed in 59 healthy individuals and the mean value measured in KPa (kiloPascal) was 16.6 ± 2.5 kPa, independent of patient age, sex or spleen size.; above the normal value it is considerd fibrosis of the tisuue of the spleen.
