Liver fibrosis screening for patients with psoriasis taking methotrexate: a cross‐sectional study comparing transient elastography and liver biopsy

Abstract Objective To evaluated the performance of FIB-4 score as a screening tool to detect significant liver fibrosis (F2) compared to transient elastography (TE) among chronic transfusion-dependent beta-thalassemia (TDT) patients, in a resource-poor setting. Design A cross-sectional study Setting Adolescent and Adult Thalassaemia Care Center (University Medical Unit) Kiribathgoda Sri Lanka. Participants 45 TDT patients who have undergone more than 100 blood transfusions with elevated serum ferritin more than 2000ng/mL were selected for the study. Patients who were serologically positive for hepatitis C antibody were excluded. Outcome measures TE and FIB-4 score were estimated at the time of recruitment in all participants. Pre-defined cut-off values for F2 extracted from previous studies for TE and FIB-4 score were compared. A new cut-off value for FIB-4 score was estimated using ROC curve analysis to improve the sensitivity for F2 prediction. Results Of the selected 45 TDT patients 22(49%) were males. FIB-4 score showed a significant linear correlation with TE (r= 0.52 p< 0.0003). The FIB-4 score was improbable to lead to a false classification of TDT patients to have F2 when the FIB-4 cut-off value was 1.3. On the other hand it had a very low diagnostic yield in missing almost all (except one) of those who had F2. Using a much-lowered cut-off point of 0.32 for FIB-4 we improved the pick-up rate of F2 to 72%. Conclusions Regardless of the cut-off point FIB-4 score cannot be used as a good screening tool to pick-up F2 in patients with TDT irrespective of their splenectomy status. On the contrary at 1.3 cut off value though FIB-4 is a very poor detector for F2 fibrosis it will not erroneously diagnose F2 fibrosis in those who do not have it.

Fibrosis Staging

Background: Non-alcoholic fatty liver disease (NAFLD) is the second most common cause of liver transplantation in the United States, with a continuously growing prevalence. There are several non-invasive methods to detect liver fibrosis, which is defined as the accumulation of extracellular matrix proteins, particularly collagens. It is most commonly associated with chronic liver diseases, such as NAFLD. Objectives: This study aimed to investigate the concordance between transient elastography (TE) and shear wave elastography (SWE) for liver fibrosis staging and also to examine the congruence between the controlled attenuation parameter (CAP) and the B-mode hepatorenal ratio for hepatic steatosis grading in patients with NAFLD. Materials and Methods: In this cross-sectional study conducted during March 2018 - 2019, NAFLD patients, referred to the liver clinic of our center for the non-invasive assessment of hepatic fibrosis, were enrolled. However, patients with sonographic features of cirrhosis, multiple hepatic masses, or moderate to large ascites were excluded; also, patients who were uncooperative during the tests were excluded. Measurements obtained by different tools were recorded. Kolmogorov-Smirnov test, Chi-square test, independent t-test, or Mann-Whitney tests, as well as Pearson’s correlation coefficient test, were used to analyze the data. Results: Sixty-five patients (male-to-female ratio, 1:13), with a median age of 47 years, were included in the study. The tools for assessing fibrosis (r = 0.9538, 95% CI: 0.9252 - 0.9717, P < 0.0001) and steatosis (r = 0.429, 95% CI: 0.2048 - 0.6104, P < 0.0001) were perfectly and moderately correlated, respectively. Sex, age, and body mass index (BMI) did not affect the results. Conclusion: The two elastography modalities showed a strong correlation for fibrosis staging in our study population. Also, the CAP and B-mode hepatorenal ratio were moderately correlated for grading hepatosteatosis. Overall, selection of the best assessment method among the studied modalities depends on factors other than internal validity.
