Millions of people worldwide suffer from iron overload toxicity diseases such as transfusional iron overload in thalassaemia and hereditary haemochromatosis. The accumulation and presence of toxic focal iron deposits causing tissue damage can also be identified in Friedreich's ataxia, Alzheimer's, Parkinson's, renal and other diseases. Different diagnostic criteria of toxicity and therapeutic interventions apply to each disease of excess or misplaced iron. Magnetic resonance imaging relaxation times T2 and T2* for monitoring iron deposits in organs and iron biomarkers such as serum ferritin and transferrin iron saturation have contributed in the elucidation of iron toxicity mechanisms and pathways, and also the evaluation of the efficacy and mode of action of chelating drugs in the treatment of diseases related to iron overload, toxicity and metabolism...

Progression of liver fibrosis in patients with hemoglobinopathies is strongly related to the severity of iron overload and the presence of chronic hepatitis C virus (HCV) infection. Effective iron chelation therapy and HCV infection eradication may prevent liver complications. The European Association for the Study of the Liver guidelines recommend interferon-free regimens for the treatment of HCV infection in patients with hemoglobinopathies. However, data regarding the use of direct-acting antiviral drugs (DAAs) in this patient population are few...

The patient was a 67-year-old woman with type 2 diabetes and non-alcoholic steatohepatitis (NASH). The administration of the sodium-glucose cotransporter 2 (SGLT2) inhibitor, ipragliflozin improved her liver dysfunction clinically and histologically. The serum alanine aminotransferase (ALT) and ferritin levels decreased to normal limits after treatment for four months. Type IV collagen and hyaluronic acid, both of which were serum fibrotic markers, decreased after treatment. Ultrasonography and computed tomography showed a decrease in the fat deposits in her liver...

INTRODUCTION: Macrophage activation syndrome (MAS) is a life-threatening hyperinflammatory state mediated by uncontrolled cytokine storm and haemophagocytosis. Although rarely reported, MAS might occur in systemic lupus erythematosus (SLE), notably as an inaugural manifestation. Glucocorticoids (GCs) are the cornerstone of SLE therapy. However, in some cases high doses of GCs are required to achieve remission (i.e. glucocorticoid-resistance), leading to significant side effects. CASE REPORT: A 28-year-old Romani male was admitted to our hospital for polyarthralgia, polyserositis and fatigability...

Multiple sclerosis is a chronic demyelinating disease of the central nervous system characterised by inflammatory and degenerative changes. It is considered that disease arises from the influence of environmental factors on genetically susceptible individuals. Recent researches, using magnetic resonance imaging, connected iron deposits in different brain regions with demyelinating process in multiple sclerosis patients. Although iron is an essential trace element important for many biological functions it could be harmful because iron excess can induce the production of reactive oxygen species, development of oxidative stress and lipid peroxidation which leads to demyelination...

BACKGROUND: Nonalcoholic steatohepatitis (NASH) is an active form of nonalcoholic fatty liver disease. Risk factors for NASH include type 2 diabetes mellitus (T2DM) and obesity. Sodium-glucose cotransporter 2 (SGLT2) inhibitors used to treat T2DM prevent glucose reabsorption in the kidney and increase glucose urinary excretion. Dapagliflozin is a potent, selective SGLT2 inhibitor that reduces hyperglycemia in patients with T2DM and has been demonstrated to reduce some complications associated with NASH in rodent models...

Gaucher disease (GD) is a lysosomal storage disorder characterized by the storage of glycosphingolipids in macrophages. Despite effective therapy, residual disease is present in varying degrees and may be associated with late complications, such as persistent bone or liver disease and increased cancer risk. Gaucher macrophages are capable of storing iron and locations of residual disease may thus be detectable with iron imaging. Forty type 1 GD (GD1) patients and 40 matched healthy controls were examined using a whole-body magnetic resonance imaging protocol consisting of standard sequences, allowing analysis of iron content per organ, expressed as R2* (Hz)...

Previous studies have detected abnormal serum ferritin levels in patients with depression; however, the results have been inconsistent. This study used quantitative susceptibility mapping (QSM) for the first time to examine brain iron concentration in depressed patients and evaluated whether it is related to severity. We included three groups of age- and gender-matched participants: 30 patients with mild-moderate depression (MD), 14 patients with major depression disorder (MDD) and 20 control subjects. All participants underwent MR scans with a 3D gradient-echo sequence reconstructing for QSM and performed the 17-item Hamilton Depression Rating Scale (HDRS) test...
