Blood rheology and proliferative retinopathy in homozygous sickle cell disease.
Some haematological and rheological features were compared in 27 age and sex matched pairs of patients (15 male, 12 female) with homozygous sickle cell (SS) disease with and without proliferative sickle retinopathy (PSR). Significant haematological differences between the groups were a higher haemoglobin and a lower fetal haemoglobin in PSR positive males and a higher MCHC in PSR positive femal...
متن کاملBlood rheology and proliferative retinopathy in sickle cell-haemoglobin C disease.
Haematological and rheological (plasma and serum viscosity, whole blood viscosity, and erythrocyte filterability) factors were studied in 31 age-sex matched pairs of patients with sickle cell haemoglobin C disease with and without proliferative sickle retinopathy (PSR). Patients with PSR had significantly higher mean cell haemoglobin and lower Hb F levels on average than the matched controls, b...
متن کاملHaematological factors associated with proliferative retinopathy in homozygous sickle cell disease.
Haematological indices were investigated in 261 patients with homozygous sickle cell disease, 29 of whom had developed proliferative sickle retinopathy (PSR). After allowing for age-related effects, male patients with high Hb (> 9 g/dl) and low HbF (< 5%) levels appeared to constitute a high risk group for PSR. This relationship was not evident in females, PSR being observed in patients with lo...
متن کاملSevere proliferative retinopathy is associated with blood hyperviscosity in sickle cell hemoglobin-C disease but not in sickle cell anemia.
Little is known about the impact of blood rheology on the occurrence of retinopathy in sickle cell disease (SCD). Fifty-nine adult SCD patients in steady-state condition participated to the study: 32 with homozygous SCD (sickle cell anemia; SCA) and 27 with sickle cell hemoglobin-C disease (SCC). The patients underwent retinal examination and were categorized according to the classification of ...
متن کاملSteady state hemoglobin concentration and packed cell volume in homozygous sickle cell disease patients in Lagos, Nigeria
Background: Sickle cell disease is a genetic disorder of hemoglobin causing myriad of pathology including anemia. The purpose of this study was to evaluate the baseline values of steady state hemoglobin and packed cell volume as a guide to managing the early recognition of hemolytic crises in sickle cell anemia. Methods: A cross-sectional study was conducted among the sickle cell patients atte...
