Sickle cell trait was included because, at that time, a great deal of speculation and new information was forthcoming regarding sudden death in military recruits who had sickle cell trait. The members of the Sports Medicine Committee believed that it was important to indicate that, in spite of these new concerns, there were no data to indicate that anyone with sickle cell trait should not be included in any athletic activities. Sickle cell disease was excluded because it is a disease with variable expression and one which is characterized by numerous exacerbations and periods of quiescence.

Although sickle cell disease has long been viewed as a contraindication to free flap transfer, little data exist evaluating complications of microsurgical procedures in the sickle cell trait patient. Reported is the case of a 55-year-old woman with sickle cell trait who underwent a deep inferior epigastric perforator (DIEP) microvascular free flap following mastectomy. The flap developed signs of venous congestion on postoperative day two but was found to have patent arterial and venous anastomoses upon exploration in the operating room. On near-infrared indocyanine green angiography, poor vascular flow was noted despite patent anastomoses and strong cutaneous arterial Doppler signals. Intrinsic microvascular compromise or sickling remains a risk in the sickle cell trait population as it does for the sickle cell disease population. Just like in sickle cell disease patients, special care should be taken to optimize anticoagulation and minimize ischemia-induced sickling for patients with sickle cell trait undergoing microsurgery.

Hyposthenuria was investigated in subjects with sickle cell trait and in patients with sickle cell anemia. The following were observed: 1) in subjects with sickle cell trait both normal and reduced maxima of urinary concentration are found, whereas all untreated patients with sickle cell anemia over 6 months of age have hyposthenuria; 2) hyposthenuria becomes increasingly more severe with advancing age in both sickle cell anemia and sickle cell trait; 3) in a 6-month-old patient with sickle cell anemia and hyposthenuria, the maxima of urinary concentration returned to normal after two transfusions of normal erythrocytes. Reasons are presented for favoring the hypothesis that hyposthenuria in sickle cell disease is due to renal damage, possibly from intravascular sickling of erythrocytes in renal vessels or from the presence of "free" circulating S-hemoglobin.

The highest frequency of sickle cell gene in India is reported in Odisha. The present study was taken up to assess the presence of sickle cell disease among febrile patients of a medical college of eastern Odisha. Patients referred from both pediatric and medicine department to the Hematology section of the department of Pathology, SCB Medical College, Cuttack were subjected to measurement of RBC indices, Sickling test, Haemoglobin Electrophoresis and Fetal Haemoglobin Estimation. Out of total 1000 referred patients 76(7.6%) were found to be positive for sickling. Two‐third of sicklingpositive patients had sickle cell trait with electrophoretic AS band. There was a significant association between age and positive sickling (χ2 = 24.357; df = 4, P = <0.0001). No significant association was observed between sickling and gender. Sickle cell positive cases are not uncommon in eastern Odisha. Our study demonstrated sickle cell trait to be more common among screened patients than other forms of sickle cell diseases.

A patient who presented with sickle retinopathy and hemoglobin electrophoresis results compatible with sickle cell trait was found, on further investigation, to be a compound heterozygote with hemoglobin S and hemoglobin New York disease. This recently reported form of sickle cell disease was not previously known to cause retinopathy and surprisingly was observed in a non-Asian individual. The ophthalmological findings, the laboratory diagnosis, and possible pathophysiology of this disorder are discussed. Persons diagnosed with sickle cell trait who present with symptoms of sickle cell disease may benefit from specific screening for this variant.

Abstract People with sickle cell disease have a chronically activated coagulation system and display hemostatic perturbations, but it is unknown whether they experience an increased risk of venous thromboembolism. We conducted a case–control study of venous thromboembolism that included 515 hospitalized black patients and 555 black controls obtained from medical clinics. All subjects were assayed for hemoglobin S and hemoglobin C genotypes. The prevalence of the S allele was 0.070 and 0.032 for case patients and controls, respectively (P < .001). The odds that a patient had sickle cell trait were approximately twice that of a control, indicating that the risk of venous thromboembolism is increased approximately 2-fold among blacks with sickle cell trait compared with those with the wild-type genotype (odds ratio = 1.8 with 95% confidence interval, 1.2-2.9). The odds ratio for pulmonary embolism and sickle cell trait was higher, 3.9 (2.2-6.9). The prevalence of sickle cell disease was also increased among case patients compared with controls. We conclude that sickle cell trait is a risk factor for venous thromboembolism and that the proportion of venous thromboembolism among blacks attributable to the mutation is approximately 7%.

0.2% of African-Americans have sickle cell anemia while, with 8% to 10% have sickle cell trait. This chapter provides an overiew of the etiology, pathophysiology, and treatment of sickle cell anemia as they affect anesthetic management—before, during, and after surgery.

Abstract A family of Greek derivation is described in which 2 out of 6 children examined exhibited a sickle cell type of anemia. The father of these children was found to have thalassemia minor and the mother the sickle cell trait. It is presumed that the anemia in the two children was due to simultaneous heterozygosity for the sickling and thalassemia genes. Biochemical studies with reference to the occurrence and amounts of normal, sickle cell, and fetal hemoglobin were carried out on the parents and the 6 children. The theoretic interpretation of the biochemical findings is discussed.
