Women who have sickle cell trait can have a healthy pregnancy. If you or your partner has sickle cell trait, you may want to talk with a genetic counsellor before getting pregnant. A genetic counsellor can help you learn more about your chances of having a child with sickle cell disease.. A person with sickle cell trait has a 1-in-2 (50%) chance of passing the sickle cell trait gene to each of his or her children. If both parents have sickle cell trait, each of their children will have a 1-in-4 (25%) chance of having sickle cell disease. ...
A 26-yr-old man with sickle cell trait (SCT) suddenly lost visual acuity in the left eye after a cycling race in hot tropical environment. The cause was massive central retinal vein occlusion (CRVO) with hemorrhaging that rapidly worsened to neovascular glaucoma. Although medically treated, the eye is now marked by total retinal detachment. Cardiovascular function assessment shows no electrocardiographic abnormalities, no anomaly in the supra-aortic tree, and no evidence of structural heart disease. Although normal coagulation markers values (i.e., activated partial thromboplastin time, prothrombin time, fibrinogen concentration, antithrombin III, factor V, proteins C and S) were observed 2.5 months after the clinical event, a transesophageal echocardiogram performed few hours after the incident revealed the presence of four thrombi in the left atrium suggesting a postexercise hypercoagulable state at that time. Hemorheological measurements at distance of the events demonstrated high red blood cell
Venous thromboembolism is the major cause of maternal mortality in the United States and there are emerging data that the thrombotic risk is higher in peripartum black women as compared to white women. The reasons are unclear: indeed, the few genetic risk factors for venous thrombosis that have been identified are more common in whites than blacks. This raises the possibility of yet undescribed mutations. To bolster this theory, some intriguing studies have noted a similar frequency of familial thrombosis in blacks and whites, supporting the existence of yet unidentified hereditary component(s). Sickle cell anemia is a genetic disease more prevalent in the black population. Whereas sickle cell anemia has been associated with a prothrombotic state, there are limited data to support a prothrombotic state in sickle cell trait. We plan to examine whether sickle cell trait might play a role in increasing the incidence of thrombosis in the black population.. Peripartum women are 4-5 times more ...
Washington, DC - This week, the Centers for Disease Control, the American Society of Hematology and the Sickle Cell Disease Association of America released an updated Sickle Cell Trait toolkit to provide community members with health education materials and resources. One in twelve African Americans are diagnosed with the Sickle Cell Trait.. Sickle Cell Disease is our nations most common inherited blood disorder, and more than three million Americas carry the Sickle Cell Trait. Tragically, far too many with the trait are unaware that they carry the trait and they have not been educated about the risk factors associated with Sickle Cell Trait, said Congresswoman Barbara Lee. This updated toolkit is an important resource for those with the Sickle Cell Trait, their families and their physicians. I urge everyone to take the time to go through this toolkit and learn more about Sickle Cell Trait.. As a member of the health funding subcommittee, I have long called for a broader public education ...
Objective: The aim of this study was to evaluate the determinants of chronic kidney disease (CKD) with special emphasis on sickle cell trait (SCT). Methods: Three hundred and fifty-nine patients (171 men and 188 women), aged 18 years or older, with reduced kidney function (eGFR < 90 ml/min/1.73 m2) and seen at secondary and tertiary healthcare in Kinshasa were consecutively recruited in this cross-sectional study. Serum creatinine and haemoglobin electrophoresis were performed in each patient. CKD was defined as < 60 ml/min/1.73 m2. Logistic regression analysis was used to assess determinants of CKD with a special emphasis on SCT. A p-value < 0.05 defined the level of statistical significance. Results: SCT was present in 19% of the study population; its frequency was 21 and 18% (p > 0.05) in patients with and without CKD, respectively. In multivariate analysis, sickle cell trait was not significantly (OR: 0.38; 95% CI: 0.559-1.839; p = 0.235) associated with CKD; the main determinants were
Two young patients with sickle cell trait (AS haemaglobinopathy) and ischaemic stroke are reported. The stroke involved the internal carotid artery territory in one and the brainstem in the other. A review of the literature is presented to suggest that the association of sickle cell trait and cerebral infarction is more than coincidental. Haemoglobin electrophoresis should be undertaken routinely in young subjects with ischaemic stroke.. ...
Since screening for the sickle cell mutation is already widely performed in the U.S., these findings present additional public health and policy implications, including the role of genetic counseling, community awareness and education around genetic findings such as sickle cell trait, he said.. In their study, the researchers analyzed data independently from African-American cohorts in five population studies. In each group they found SCT increased risk between 1.5 and 2 times. Altogether the analysis included data from 15,975 people. One of the convincing things is that the results were the same across all five studies, Wilson said. Dr. Adolfo Correa is University of Mississippi professor of medicine and pediatrics and interim director of the Jackson Heart Study, one of the five cohorts included in the investigation. These findings begin to open up a whole new horizon for research, he said. Now that we appreciate that sickle cell trait can have an impact on kidney disease, we need to ...
Atomic force microscopy (AFM) allows for high-resolution topography studies of biological cells and measurement of their mechanical properties in physiological conditions. In this work, AFM was employed to measure the stiffness of abnormal human red blood cells (RBCs) from patients with the genotype for sickle cell trait. The determined Youngs modulus was compared with that obtained from measurements of erythrocytes from healthy subjects. The results showed that the Youngs modulus of pathological erythrocytes was approximately three times higher than in normal cells. Observed differences indicate the effect of hemoglobin S as well as possible changes in the organization of the cell cytoskeleton associated with the sickle cell trait.. Copyright © 2010 by ASME ...
The sickle cell trait could be a cause?albeit rare?of sudden death in young African-American competitive athletes, most commonly during football training, according to a scientific poster that will be presented at the American College of Cardiology (ACC) Scientific Sessions, April 1-3, in New Orleans.. The sickle cell trait (SCT), which affects approximately 8 percent of African-Americans in the U.S., has been associated with sudden death in military recruits undergoing vigorous exercise. Due to the potential hypothesis that SCT may also cause sudden death in young highly trained athletes during physical activity, the National Collegiate Athletic Association (NCAA) has recently made screening of athletes for SCT mandatory for all Division I athletes prior to their participation in college athletics. However, Kevin M. Harris, MD, co-director of the Acute Aortic Dissection Program and director of the echocardiography laboratory at the Minneapolis Heart Institute® at Abbott Northwestern Hospital ...
When a child inherits the gene for sickle cell anemia from just one parent, its referred to as sickle cell trait. Sickle cell trait does not cause anemia. However, when other common genetic conditions are present, sickle cell trait can cause symptoms like those of sickle cell anemia. These symptoms can appear when you engage in strenuous activities or sports. You can experience shortness of breath, coldness in the hands and feet, pale skin, chest pain or headaches. And if you have sickle cell trait, you are at risk of having a child with either sickle cell trait or sickle cell disease.. ...

Recent studies in Kenya and Ghana have shown that individuals who inherit two malaria-protective genetic disorders of haemoglobin-α(+) thalassaemia and sickle cell trait-experience a much lower level of malaria protection than those who inherit sickle cell trait alone. We have previously demonstrated that this can limit the frequency of α(+) thalassaemia in a population in which sickle cell is present, which may account for the frequency of α(+) thalassaemia in sub-Saharan Africa not exceeding 50%. Here we consider the relationship between α(+) thalassaemia and sickle cell in South Asian populations, and show that very high levels of α(+) thalassaemia combined with varying levels of malaria selection can explain why sickle cell has penetrated certain South Asian populations but not others.

When WHO has laid down correct Terminology [34 35], we find reputable publications/Guidelines riddled with confusion, most glaringly confusing Sickle Cell Trait with Sickle Cell Disease [36-40], and sometimes describing both Trait and Disease phenotypes in same person - [41] all of which mistakes have been exposed [42-49]. Doyen of Abnormal Haemoglobins Professor Hermann Lehmann FRS wrote to The Times-London [50] that Sickle Cell Traits had run at Olympic Games at Mexico City 7000 ft and won Gold Medals, yet reports of Sickle Cell Traits dying at 4000ft continued, ensuring Insurance Companies made huge profits.

Sickle cell trait (SCT), or sicklemia, affects around 1-3 million people in the US and 8-10% of African Americans. It is an inherited condition in which an individual carries a single copy of the gene that causes sickle cell disease - a group of inherited red blood cell disorders - but people with SCT never develop the disease.

The final section of the 1949 paper discussed genetics. The Caltech authors stated that people suffering from sickle cell anemia were homozygous, whereas people with sickle cell trait were heterozygous. The Longsworth scanning diagrams that they reproduced with their article, definitively show that those with sickle cell trait hemoglobin have two distinct peaks - one that resembles the peak of sickle cell anemia hemoglobin and one that resembles the peak of normal hemoglobin. Thus, they found that sicklemics had one normal allele producing normal hemoglobin and one sickle cell allele producing sickled hemoglobin. In their discussion on genetics, the authors mentioned that geneticist James V. Neel of the Heredity Clinic at University of Michigan had published a paper earlier that year and proposed the same genetic conclusion. Neel had analyzed the blood of parents and their children and concluded that sickle cell trait is a heterozygous trait, and sickle cell anemia is homozygous recessive. ...
Author. By Munsoor M.Munsoor, Afaf Alabid.. Abstracts. This is an analytical hospital based study carried out in relatives of patients suffering from sickle cell disease (SCD) who referred to Elobied Hospital. The aim of this study was to estimate the frequency of sickle cell trait (HbAS) among those relatives and to assess their CBC. One hundred persons of seventeen different tribes were included (48% males and 52% females) with an age ranged between 4 to 70 years. From each person, 2.5 mL of venous blood was collected into EDTA container. Blood film, complete blood count (CBC) and sickling test were performed immediately. Then haemolysate was made and stored at ( 20 ◌C) for electrophoresis test. The results of hemoglobin electrophoresis show that, 54% of target samples were heterozygous carrier (HbAS) while 42% were normal (HbAA) and 4% were diagnosed as sickle cell disease (HbSS). The highest distribution of sickle cell trait was among Bederia tribe 9 (23.1%) followed by Fulani and Selehab ...
Sickle Cell Disease (continued from previous page) Sickle cell is a disease that affects the oxygen-carrying red blood cells. While normal red blood cells with HbA are round with a doughnut-like indentation to carry oxygen, the HbS gene causes the red blood cells to become abnormally crescent-shaped and rigid. Sickled red blood cells get caught in the bodys smaller blood vessels, blocking normal blood flow and causing severe pain and damage to the delicate tissues of the lungs, eyes, spleen, kidneys and liver. People with one copy of the HbS gene are carriers of the sickle cell trait and may experience some symptoms. People with two copies of the gene develop sickle cell anemia/disease, which can be deadly.. How does the sickle cell trait help people resist malaria? The malaria parasite gains entrance to the bloodstream through a mosquito bite and begins to destroy the normal round-shaped red blood cells that carry oxygen throughout the body. Many of the red blood cells of people with one ...
its passed down from parents to children. Like you, lots of people dont have the disease, but they can have the sickle cell gene in their bodies. When someone has the gene but not the disease, its known as sickle cell trait.. Your doctors office can do an easy blood test to find out if you have sickle cell trait. If the test shows you have the gene in your body, it means that you could pass it on to your children.. Of course, children inherit genes from both parents. So your kids dad will play a role in sickle cell disease:. ...
Individuals carrying just one copy of the sickle mutation (inherited from either the father or mother) were known not to develop sickle cell anemia, leading rather normal lives. However, it was found that these same individuals, said to carry the sickle cell trait, were in fact highly protected against malaria, thus explaining the high prevalence of this mutation in geographical areas where malaria is endemic.. These findings lead to the widespread believe in the medical community that understanding the mechanism whereby sickle cell trait protects against malaria would provide critical insight into developing treatment or a possible cure for this devastating disease, responsible for over a million premature deaths in sub-Saharan Africa. Despite several decades of research, the mechanism underlying this protective effect remained elusive. Until now.. Several studies suggested that, in one way or another, sickle hemoglobin might get in the way of the Plasmodium parasite infecting red blood cells, ...
Sickle beta plus thalassemia - Do beta thalassemia and sickle cell anemia always reduce life expectancy? Not if just 1 trait. Having either beta thalassemia trait or sickle cell trait is a mild condition and should not cause symptoms to the point of making a person frequently ill nor shortening life expectancy. Having beta thalassemia major or sickle cell disease, or both sickle cell trait and beta thalassemia trait, usually causes severe enough chronic disease symptoms to shorten lifespan an uncertain amount.
Malaria and Sickle Cell Anemia: Malaria is a deadly parasitic disease which results in over 1 million deaths annually. It is carried by mosquitoes. Humans have tried to control the disease by attacking the parasite, P. falciparium, with drugs or by using pesticides to control the mosquitoes. In both cases, the organisms have developed resistance. Malaria is common in Africa and many people of African descent have either sickle cell anemia or sickle cell trait. . Sickle cell anemia is a deadly condition itself, however, the more commonly occurring sickle cell trait reduces the occurrence of malaria by making infection by P. falciparium less likely, hence this adaptation has been selected for and retained in human populations.

Contrary to earlier report by Lehmann and Rapper [7], our results show that, the prevalence of the AS carrier state was highest in Eastern Uganda, followed by Bundibugyo (see Figure 1-map of Uganda, and Figure 2 for distribution of results). The fact that the first survey on sickle cell disease (SCD) in Uganda was done over 60 years ago, and no similar surveys have been conducted since then; it is not surprising that SCD has changed its dynamics. This is because the inherited nature of the SCD trait predicts likely changes in the prevalence and distribution of the same depending on the prevailing biological (malaria interventions) and social factors (marriage patterns). Indeed, contrary to an earlier report of 45% prevalence of the AS trait in Bundibugyo, we found the current AS prevalence to be 13.4%; changes that we have appropriated to the possible earlier adoption of intermarriage-avoidance in Bundibugyo resulting from a similarly earlier knowledge of AS prevalence [7]. Specifically, ...
Here we have demonstrated that low O2 concentrations impair parasite growth in RBCs containing HbAS. While the Hb polymerization observed does not typically occur in heterozygous carriers of HbS, it can occur in extreme conditions like the prolonged hypoxia occurring during sequestration. In our experiments, both infected and uninfected cells have prolonged exposure to hypoxic conditions and may even sickle at the cellular level. In vivo, we postulate that only infected RBCs that express PfEMP1 will demonstrate significant Hb polymerization, because they are the only cells that sequester into the hypoxic microvasculature. This was particularly significant at 5% and 7.5% O2 concentrations, which most closely simulate the environment in the microcirculation (25⇓⇓⇓⇓-30). At these O2 concentrations, we observed an intermediate phenotype that accounts for the incomplete phenotype of reduced parasite densities observed in AS individuals. It was also notable that in the 1% and 3% O2 ...
Our study is the first to suggest that SCT could worsen the vascular dysfunction among patients with T2DM. In addition, we found elevated blood viscosity and oxidative stress in patients with T2DM-SCT, which, in association with the vascular dysfunction, could increase the risk for vascular disorders in this population.. The principal aim of this study was to test whether the presence of SCT could worsen the vascular dysfunction and the biological abnormalities observed in patients with T2DM. Despite the fact that individuals with T2DM were older than subjects with T2DM-SCT, their vascular function was less altered. PWV, FMD, and corrected FMD were blunted in subjects with T2DM-SCT compared with the three other groups, demonstrating increased arterial stiffness and a loss of vascular reactivity in these subjects, which, in other diseases, have been shown to increase the risks for cardiovascular morbidity and/or mortality (27,28). In agreement with this assumption, a higher number of participants ...

Because the genetic disorder is incompletely recessive, a person with only one SCA allele and one unaffected allele will have a mixed phenotype: The sufferer will not experience the ill effects of the disease, yet will still possess a sickle cell trait, whereby some of the red blood cells undergo benign effects of SCA, but nothing severe enough to be harmful. Those afflicted with sickle-cell trait are also known as carriers: If two carriers have a child, there is a 25% chance their child will have SCA, a 50% chance their child will be a carrier, and a 25% chance that the child will neither have SCA nor be a carrier. Were the presence of the SCA allele to confer only negative traits, its allele frequency would be expected to decrease generation after generation, until its presence were completely eliminated by selection and by chance. However, convincing evidence indicates, in areas with persistent malaria outbreaks, individuals with the heterozygous state have a distinct advantage (and this is ...

The sickle cell test is available as part of haemoglobinopathy screening. Hb S is an abnormal haemoglobin caused by a single point substitution of valine for glutamic acid in position 6 of the β-globin chain. The homozygous state, sickle cell anaemia, is characterised by the formation of sickle red cells and moderate to severe anaemia. Sickle cell trait, the heterozygous state, is very common, with no associated haematological abnormalities. In vivo sickling occurs only at very high altitudes and at low oxygen pressures. The sickle solubility screen provides a quick and reliable method of detecting this abnormal haemoglobin. The test is based on the principle that Hb S, in its reduced state, is less soluble in concentrated phosphate buffers than nearly all other haemoglobins (the exceptions being the rare Hb C Harlem and Hb C Georgetown). A sickle screen is required for patients in high risk groups, especially prior to a general anaesthetic and if there is no prior haemoglobin electrophoresis ...
Sickle-cell disease occurs when a person inherits two abnormal copies of the hemoglobin gene, one from each parent. This gene occurs in chromosome 1. Several subtypes exist, depending on the exact mutation in each haemoglobin gene. An attack can be set off by temperature changes, stress,dehydration, and high altitude.A person with a single abnormal copy does not usually have symptoms and is said to have sickle cell trait. Such people are also referred to as carriers. Diagnosis is by a blood test and some countries test all babies at birth for the disease. Diagnosis is also possible during pregnancy.The care of people with sickle-cell disease may include infection prevention with vaccination and antibiotics , high fluid intake , folic acid supplementation, and pain medication. Other measures may include blood transfusion, and the medication hydroxycarbamide (hydroxyurea)A small proportion of people can be cured by transplant of bone marrow ...

Background on Disease Markers The disease that we chose was Sickle Cell Anemia. Sickle Cell is a inherited disease that comes from both parents. If only one parent has the Sickle Cell trait, then the child will be a carrier. If both parents have the trait, then the child will have Sickle Cell. This disease causes the red blood cells to change into a crescent shape instead of being disk shape resulting in the loss of efficient oxygen delivery. It can also result in clotting because the blood cells can not make it through small blood vessels very well. The SNP for this disease is 78478128 and the reference SNP is rs78478128. The link to the page with more info on Sickle cell is http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001554/ The link to the page with the genetic information and SNP is http://www.ncbi.nlm.nih.gov/projects/SNP/snp_ref.cgi?rs=78478128#locus ...
Hemoglobin S is an abnormal version of the protein hemoglobin . The sixth amino acid of the normal beta chain, glutamic acid , is replaced by valine with gluconic acid . This mutation causes the red blood cell to take on a sickle shape, and is the cause of the sickle cell trait condition (when the individual is heterozygous for this mutant hemoglobin) and the disease of sickle cell anemia (when the individual is homozygous for this mutant hemoglobin ...
