Longitudinal changes in LIC LIC and other parameters in patients receiving different chelation regimens: Data from LICNET LICNET

摘要

Abstract Objectives The liver remains the primary site of iron storage, with liver iron concentration ( LIC ) being a strong surrogate of total body iron. MRI ‐R2 can accurately measure LIC . The LICNET (Liver Iron Cutino Network) was established to diagnostics of liver iron overload by MRI ‐R2 subjects with hemochromatosis in hematological disorders. The aims of the study were to look at variation in LIC measurements during time across different chelation regimens. Methods This was a cross‐sectional study of 130 patients attending 9 Italian centers participating in the LICNET . LIC comparisons over time (T 0 and T 1 ) were made using t test and/or Wilcoxon test. Results LIC significantly decreased from MRI 1 to MRI 2 although at high variance (median change ?0.8?mg Fe/g dw, range: ?29.0 to 33.0; P? =?.011) and 7.7% of patients shifted from LIC values of high risk (15?mg Fe/g dw) to an intermediate‐risk category (7‐15?mg Fe/g dw). Median change in LIC and correlation with serum ferritin levels ( SF ), during different chelation regimens, is reported. Conclusions These findings suggest as longitudinal variation in the LIC is possible, across all chelation regimens. It confirms as SF levels not always can be used for estimating changes in LIC .
