Exertional sickling: questions and controversy
Sickle cell trait (SCT) occurs in about 8% of African-Americans and is often described to be of little clinical consequence. Over time, a number of risks have emerged, and among these are rare but catastrophic episodes of sudden death in athletes and other individuals associated with physical activities which is often described as exercise collapse associated with sickle trait (ECAST). Despite ...
متن کاملMacular and perimacular vascular remodelling sickling haemoglobinopathies.
The posterior pole vasculature of 100 patients with different sickling haemoglobinopathies was studied prospectively over a period of three years. Various abnormalities of the posterior pole vasculature were seen in 29 per cent of the patients. Continuous remodelling of the macular and perimacular vasculature occurred. Visual acuity was variably affected and sometimes remained intact.
متن کاملErythrocyte sickling during exercise and thermal stress.
OBJECTIVE To examine effects of exercise in the heat and fluid intake on erythrocyte sickling and neutrophil activation in carriers of sickle cell trait (HbAS). DESIGN, SETTING, AND PARTICIPANTS Six African American men (2 HbAS; 42% HbS, 4 HbAA; 20.7 +/- 0.8 years; 87.4 +/- 9.6 kg) participated in 2 randomized sessions (separate days) each consisting of 45 minutes of brisk walking (treadmill)...
متن کاملLi+ and sickling of homozygous HbS cells.
Vol.31, No. 4, 1985 649 tecting hypercholesterolemia must have the best possible analytical performance. We suggest that, in screening a population for hypercholesterolemia, serum or plasma samples are preferable to blood spots on fiter paper. Instruments such as the Cobas-Bio centrifugal analyzer require less than 50 L of sample and the typical overall CV is 4% for assays of cholesterol in pla...
متن کاملRed cells shrink during sickling.
Rapid transformatIon of discoid hemoglobin SS erythrocytes into grossly distorted sickled forms suggests alteration of surface/volume ratio. We, therefore, examined the effect of deoxygenation on red cell volume. ‘31llaholed albumin was used as a marker of plasma volume in normal (Hb AA), sickle (Hb SS), and sickle-C (Hb SC) blood. Heparinized blood was incubated for 30 mm at 37#{176}Cin a tpno...
