Obesity, liver steatosis and metabolic syndrome: The hidden enemies in transfusion‐dependent thalassaemia.

In their paper, the authors quantified liver iron concentration (LIC) and hepatic steatosis (HS) using MRI‐T2* technology in transfusion‐dependent thalassaemia (TDT) patients and healthy controls and found that the prevalence of HS among patients with TDT was 36.4%. In comparison with healthy controls, the hepatic fat fraction (FF) was significantly higher in the TDT population (p = 0.013). Active hepatitis C virus infection, body mass index (BMI) and LIC were independent predictors of HS. An inverse correlation between hepatic FF and high‐density lipoprotein cholesterol (p = 0.042) and a significant association of high glycaemia level (p = 0.037) with higher hepatic FF and a significant relationship (p = 0.026) between HS and higher BMI (though in a 'lean' group of patients) in TDT patients indicated that 'metabolic syndrome' was present in this subset with TDT. The impact of metabolic syndrome on TDT, including cardiac disease unrelated to iron overload, needs further study. Commentary on: Ricchi et al.
