Objectives and importance: Patients with multiple myeloma (MM) have an increased risk of cardiovascular comorbidities due to disease burden and treatment-related risk factors. Proteasome inhibitors, including bortezomib and carfilzomib, are effective and generally well tolerated anti-MM agents. However, cardiovascular-related toxicities have been reported with this class of agents, the mechanisms of which are not fully understood. We discuss the practical management of cardiovascular events during carfilzomib therapy for relapsed MM...

OBJECTIVES: We report a case of a 7-year-old girl with severe hypochromic microcytic anemia, who was unresponsive to classical iron supplements. We suspected IRIDA, iron-refractory iron-deficiency anemia, a genetic iron metabolism disorder, caused by TMPRSS6 variations. TMPRSS6 encodes matriptase-2, a negative regulator of hepcidin, and its pathological variants are related to normal to high levels of hepcidin. We analyzed the TMPRSS6 gene and we improved clinical management of the patient, selecting the appropriate supplementation therapy...
