background functional iron deficiency (fid) may cause erythropoietin resistance in patients under hemodialysis (hd). since the role of chronic inflammation or oxidative stress in its pathogenesis is unclear, controversy remains to whether intravenous iron or intravenous ascorbic acid (an antioxidant) can improve this anemia due to decreased iron availability. objectives the current study compar...

background: vitamin d (vit d) is linked to various conditions including musculoskeletal, metabolic and   cardiopulmonary diseases. however, it is not clear whether correction of vit d deficiency exerts any beneficial effect in patients with pulmonary hypertension. methods: this study was a prospective uncontrolled longitudinal study. patients with pulmonary hypertension and vit d deficiency wer...
