BACKGROUND: Multiple myeloma (MM) is a malignant disease with a 10% frequency among all haematology neoplasms. It is characterized by clone proliferation of plasmatic cells in bone marrow, monoclonal gammopathy, and anemia, hypercalcemia, and kidney failure and bone lesions. IL-6 is an inflammatory cytokine, potential growth factor for myeloma cells, as elevated serum levels are connected with poor disease prognosis. IL-6 modulates many gene transcriptions, encoding synthesis of acute phase proteins, including C-reactive protein (CRP) and hepcidin...

Cigarette smoking results in the accumulation of iron both systemically and locally, in the lung thereby causing imbalance in iron homeostasis. This disruption in iron homeostasis can be associated with oxidative stress and consequent tissue injury. Therefore, in this study, we tested the association between iron homeostasis and airway obstruction by examining a large cohort of smokers and non-smokers for relationships between 1) serum ferritin and iron concentrations and transferrin saturation and 2) forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and their ratio (FEV1/FVC)...
