Iron deficiency is a frequent comorbidity of chronic diseases such as inflammatory bowel disease that can severely impact the health and quality of life of affected individuals. It can exist as a silent condition and manifest in non-specific symptoms even in the absence of anemia. Even though iron deficiency anemia is the most common complication and extra-intestinal manifestation of inflammatory bowel disease, the majority of inflammatory bowel disease patients who are diagnosed with iron deficiency anemia are not treated. Areas covered: In this review, we discuss iron deficiency and iron deficiency anemia in patients with inflammatory bowel disease, and review diagnostic and therapeutic options. Expert commentary: We invite international gastroenterological societies and associations to refine the practice guidelines and include iron deficiency as a potential morbidity associated with IBD in analogy to arthritis, uveitis or any other extra intestinal manifestations. There should a more unanimous agreement among different societies on the specific diagnostic cutoff values for C-reactive protein levels, serum ferritin, and transferrin saturation in order to differentiate iron deficiency anemia from anemia of chronic disease.

The incidence of hepatocellular carcinoma (HCC) in patients with thalassemia is increasing, the two well recognized HCC risk factors in thalassemia being iron overload and chronic hepatitis C. The carcinogenicity of iron is related to its induction of oxidative damage, whereas chronic hepatitis leads to necroinflammation that can accelerate progression to HCC. We hereby report the case of a non transfused, hepatitis C-negative, β-thalassemia intermedia (β-TI) patient from our practice who had evidence of significant iron overload, suggesting the importance of increased iron burden as a HCC risk factor in this patient population. As such, screening thalassemia patients using magnetic resonance imaging (MRI)-based liver iron concentration (LIC) measurement and liver ultrasound is strongly recommended for early detection of iron overload and HCC, respectively. Data appears to be lacking on HCC treatment outcomes in patients who have thalassemia, but an approach tailored to each patient's comorbidities is key to treatment success. The prognosis of these patients can be improved by multicenter studies investigating novel HCC therapeutic targets in the thalassemia realm.
