Patients with haematologic malignancies appear to have a greater risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and severe disease due to myelosuppression.

Hepcidin, the liver peptide hormone that regulates plasma iron concentration by blocking ferroportin function,4 is at the crossroad between iron metabolism and inflammation, being positively regulated by iron itself and proinflammatory cytokines,5 and may represent the link between iron deficiency and COVID-19 severity.

Anaemia is a public health problem. Two aetiologies of microcytic anaemia are relatively common in Tunisia: iron deficiency anaemia (IDA)…

Myelodysplastic syndromes (MDS) are clonal haematopoietic disorders of pluripotent stem cells, characterised by ineffective haematopoiesis…

Gadolinium-based contrast agents are widely used for MRI. Although they may be considered well-tolerated at recommended dosing levels, recent evidence supports the deposition of free gadolinium in the tissues and its slow release into circulation, resulting in long-term toxicity, which is aggravated in renal patients.

The authors revisited the phenomenon of asymptomatic patients despite very low pulse oximetry readings, the so-called ‘sweet hypoxia’, ‘happy hypoxia’, or ‘silent hypoxaemia’.

Spontaneous renal artery dissection (SRAD) is a rare and often unrecognised clinical entity, which accounts for 1–2% of all arterial dissections. It can be the result of several underlying diseases, such as atherosclerosis, malignant hypertension, fibromuscular dysplasia, and connective tissue disorders.

The purpose of this study was to evaluate the effects of haemodialysis (HD) on B-cell subsets, in terms of untimely expression of immunosenescent phenotype.
