Impaired blood rheology plays a role inthe chronic disorders associated with sickle cell- hemoglobin C disease: Blood viscosity in hemoglobin SC disease

Abstract : Lionnet et al. recently reported a high prevalence of retinopathy (RET) and otologic disorders (OTD) in patients with sickle cell-hemoglobin C disease (SC), while a significant number of patients had renal diseases (mainly glomerulopathy; GLO) and osteonecrosis (OST). The pathophysiological processes of these complications in SC are not well defined, although blood hyperviscosity has been suspected, but never tested to the best of our knowledge, as responsible for several chronic complications in SC disease1,2. The aim of this study was to analyze the associations between hematological and hemorheological parameters and chronic complications in adult SC patients.
