Abstract
Aims: In a longitudinal study, we aimed to assess the correlation between ultrasound transient elastography (TE), serum ferritin (SF), liver iron content (LIC) by magnetic resonance imaging (MRI) T2* along with the fibrosis-4 (FIB-4) score as a screening tool to detect significant liver fibrosis among chronically transfusion-dependent beta-thalassemia (TDT) patients.
Methods: The study was conducted at a tertiary health center treating TDT patients. Transient elastography was performed within 3 months of Liver MRI T2* examinations at the radiology department over a median of one-year duration. T-test for independent data or Mann-Whitney U test was used to analyze group differences. Spearman correlation with linear regression analysis was used to evaluate the correlation between TE liver stiffness measurements, Liver MRI T2* values, and SF levels.
Results: In this study on 91 patients, the median age (IQR) of the subjects was 33 (9) years, and the median (IQR) body mass index was 23.8 (6.1) kg/m2. Median (IQR) TE by fibroscan, MRI T2*(3T), Liver iron concentration (LIC) by MRI Liver T2*, and SF levels were 6.38 (2.6) kPa, 32.4 (18) milliseconds, 7(9) g/dry wt., and 1881 (2969) ng/mL, respectively. TE measurements correlated with LIC g/dry wt. (rS =0.39, p=0.0001) and with SF level (rS =0.43, P=0.001) but not with MRI T2* values (rS =-0.24; P=0.98).
Conclusion: In TDT patients, liver stiffness measured as TE decreased significantly with improved iron overload measured as LIC by MRI and SF levels. However, there was no correlation of TE with the fibrosis-4 (FIB-4) score.
期刊介绍:
Reciprocal interdependence between infectious and hematologic diseases (malignant and non-malignant) is well known. This relationship is particularly evident in Mediterranean countries. Parasitosis as Malaria, Leishmaniosis, B Hookworms, Teniasis, very common in the southeast Mediterranean area, infect about a billion people and manifest prevalently with anemia so that they are usually diagnosed mostly by experienced hematologist on blood or bone marrow smear. On the other hand, infections are also a significant problem in patients affected by hematological malignancies. The blood is the primary vector of HIV infection, which otherwise manifest with symptoms related to a reduction in T lymphocytes. In turn, infections can favor the insurgency of hematological malignancies. The causative relationship between Epstein-Barr virus infection, Helicobacter pylori, hepatitis C virus, HIV and lymphoproliferative diseases is well known.
