Polymer structure and solubility of deoxyhemoglobin S in the presence of high concentrations of volume-excluding 70-kDa dextran. Effects of non-s hemoglobins and inhibitors. (1/2332)

Earlier observations indicated that volume exclusion by admixed non-hemoglobin macromolecules lowered the polymer solubility ("Csat") of deoxyhemoglobin (Hb) S, presumably by increasing its activity. In view of the potential usefulness of these observations for in vitro studies of sickling-related polymerization, we examined the ultrastructure, solubility behavior, and phase distributions of deoxygenated mixtures of Hb S with 70-kDa dextran, a relatively inert, low ionic strength space-filling macromolecule. Increasing admixture of dextran progressively lowered the Csat of deoxyHb S. With 12 g/dl dextran, a 5-fold decrease in apparent Csat ("dextran-Csat") was obtained together with acceptable sensitivity and proportionality with the standard Csat when assessing the effects of non-S Hb admixtures (A, C, and F) or polymerization inhibitors (alkylureas or phenylalanine). The volume fraction of dextran excluding Hb was 70-75% of total deoxyHb-dextran (12 g/dl) volumes. Electron microscopy showed polymer fibers and fiber-to-crystal transitions indistinguishable from those formed without dextran. Thus when Hb quantities are limited, as with genetically engineered recombinant Hbs or transgenic sickle mice, the dextran-Csat provides convenient and reliable screening of effects of Hb S modifications on polymerization under near-physiological conditions, avoiding problems of high ionic strength.  (+info)

Sustained induction of fetal hemoglobin by pulse butyrate therapy in sickle cell disease. (2/2332)

High levels of fetal hemoglobin (Hb F) protect from many of the complications of sickle cell disease and lead to improved survival. Butyrate and other short chain fatty acids were previously shown to increase Hb F production in erythroid cells in vitro and in animal models in vivo. However, butyrates are also known to inhibit the proliferation of many cell types, including erythroid cells. Experience with the use of butyrate in animal models and in early clinical trials demonstrated that the Hb F response may be lost after prolonged administration of high doses of butyrate. We hypothesized that this loss of response may be a result of the antiproliferative effects of butyrate. We designed a regimen consisting of intermittent or pulse therapy in which butyrate was administered for 4 days followed by 10 to 24 days with no drug exposure. This pulse regimen induced fetal globin gene expression in 9 of 11 patients. The mean Hb F in this group increased from 7.2% to 21.0% (P <.002) after intermittent butyrate therapy for a mean duration of 29.9 weeks. This was associated with a parallel increase in the number of F cells and F reticulocytes. The total hemoglobin levels also increased from a mean of 7.8 g/dL to a mean of 8.8 g/dL (P <.006). The increased levels of Hb F were sustained in all responders, including 1 patient who has been on pulse butyrate therapy for more than 28 months. This regimen, which resulted in a marked and sustained increase in Hb F levels in more than two thirds of the adult sickle cell patients enrolled in this study, was well tolerated without adverse side effects. These encouraging results require confirmation along with an appropriate evaluation of clinical outcomes in a larger number of patients with sickle cell disease.  (+info)

In vivo blood flow abnormalities in the transgenic knockout sickle cell mouse. (3/2332)

The accepted importance of circulatory impairment to sickle cell anemia remains to be verified by in vivo experimentation. Intravital microscopy studies of blood flow in patients are limited to circulations that can be viewed noninvasively and are restricted from deliberate perturbations of the circulation. Further knowledge of sickle blood flow abnormalities has awaited an animal model of human sickle cell disease. We compared blood flow in the mucosal-intestinal microvessels of normal mice with that in transgenic knockout sickle cell mice that have erythrocytes containing only human hemoglobin S and that exhibit a degree of hemolytic anemia and pathological complications similar to the human disease. In sickle cell mice, in addition to seeing blood flow abnormalities such as sludging in all microvessels, we detected decreased blood flow velocity in venules of all diameters. Flow responses to hyperoxia in both normal and sickle cell mice were dramatic, but opposite: Hyperoxia promptly slowed or halted flow in normal mice but markedly enhanced flow in sickle cell mice. Intravital microscopic studies of this murine model provide important insights into sickle cell blood flow abnormalities and suggest that this model can be used to evaluate the causes of abnormal flow and new approaches to therapy of sickle cell disease.  (+info)

Development of viral vectors for gene therapy of beta-chain hemoglobinopathies: optimization of a gamma-globin gene expression cassette. (5/2332)

Progress toward gene therapy of beta-chain hemoglobinopathies has been limited in part by poor expression of globin genes in virus vectors. To derive an optimal expression cassette, we systematically analyzed the sequence requirements and relative strengths of the Agamma- and beta-globin promoters, the activities of various erythroid-specific enhancers, and the importance of flanking and intronic sequences. Expression was analyzed by RNase protection after stable plasmid transfection of the murine erythroleukemia cell line, MEL585. Promoter truncation studies showed that the Agamma-globin promoter could be deleted to -159 without affecting expression, while deleting the beta-globin promoter to -127 actually increased expression compared with longer fragments. Expression from the optimal beta-globin gene promoter was consistently higher than that from the optimal Agamma-globin promoter, regardless of the enhancer used. Enhancers tested included a 2.5-kb composite of the beta-globin locus control region (termed a muLCR), a combination of the HS2 and HS3 core elements of the LCR, and the HS-40 core element of the alpha-globin locus. All three enhancers increased expression from the beta-globin gene to roughly the same extent, while the HS-40 element was notably less effective with the Agamma-globin gene. However, the HS-40 element was able to efficiently enhance expression of a Agamma-globin gene linked to the beta-globin promoter. Inclusion of extended 3' sequences from either the beta-globin or the Agamma-globin genes had no significant effect on expression. A 714-bp internal deletion of Agamma-globin intron 2 unexpectedly increased expression more than twofold. With the combination of a -127 beta-globin promoter, an Agamma-globin gene with the internal deletion of intron 2, and a single copy of the HS-40 enhancer, gamma-globin expression averaged 166% of murine alpha-globin mRNA per copy in six pools and 105% in nine clones. When placed in a retrovirus vector, this cassette was also expressed at high levels in MEL585 cells (averaging 75% of murine alpha-globin mRNA per copy) without reducing virus titers. However, recombined provirus or aberrant splicing was observed in 5 of 12 clones, indicating a significant degree of genetic instability. Taken together, these data demonstrate the development of an optimal expression cassette for gamma-globin capable of efficient expression in a retrovirus vector and form the basis for further refinement of vectors containing this cassette.  (+info)

Osteonecrosis of the hip in sickle-cell disease associated with tuberculous arthritis. A review of 15 cases. (6/2332)

We report a study of 15 cases of tuberculous hips with sickle-cell disease who presented during 1991-1993. Although the osteonecrosis was long-standing, biopsy was nearly always required to reveal the more recent tuberculous infection. Management consisted of 6 months of anti-tuberculous chemotherapy with appropriate palliative surgery 5-8 weeks after the start of drug treatment. The operative techniques which we used are described. The results were good both post-operatively, and in 12 patients followed-up at an average of 3 years. We recommend this combined management for the treatment of secondary tuberculous infections of hips previously damaged by sickle-cell disease.  (+info)

Perceived stress factors and coping mechanisms among mothers of children with sickle cell disease in western Nigeria. (8/2332)

While many studies have looked at the stressful effects of chronic illness of those who suffer such conditions, less is known about the effects on caregivers, especially in developing countries. Mothers in particular must bear the brunt of care and stress for children who have sickle cell disease (SCD). A sample of 200 mothers attending six SCD clinics in both public and private hospitals in the Ibadan-Ibarapa Health Zone of Oyo State, Nigeria, were interviewed. Stress levels were measured using an instrument comprised of stressors listed by mothers themselves in focus group discussions that preceded the survey. Higher levels of stress were associated with less educated and older women, as well as non-married women and those in polygamous households. Stress levels were also greater when there was more than one child with SCD in the family and when the index child was of school age. Coping mechanisms varied according to the category of stressor. Financial stress and disease factors were met with confrontation while family sources of stress were either complained about, accepted or avoided. Knowledge of the different types of mothers who experience more stress and of their preferred coping mechanisms can be useful in designing clinic-based counseling.  (+info)

Result: The overall sensitivity of ultrasound in diagnosing osteomyelitis was 74% with a specificity of 63%. The principal ultrasonographic finding of subperiosteal fluid was present in 14 (74%) patients with osteomyelitis and seven (37%) patients without infection. A finding ...
Treatment of Sickle cell anemia is an inherited form of anemia - a condition in which there arent enough healthy red blood cells to carry oxygen throughout your body, Under normal circumstances, your red blood cells are flexible and round, and they move easily through your blood vessels to carry oxygen to all parts of your body. In people with sickle cell anemia, the red blood cells become rigid and sticky and are shaped like sickles or crescent moons, These irregular-shaped blood cells die prematurely, resulting in a chronic shortage of red blood cells. Plus, they can get stuck when traveling through small blood vessels, which can slow or block blood flow and oxygen to certain parts of the body. This produces pain and can lead to the serious complications of sickle cell anemia, Theres no cure for most people with sickle cell anemia. However, treatments can relieve pain and prevent further problems associated with sickle cell anemia, Sickle Cell Anemia, Sickle Cell Disease, Sickle Cell Anemia Symptoms

Background: Sickle cell anaemia is an autosomal recessive disorder that arises due to the substitution of glutamic acid with valine. This occurs at position 6 of the haemoglobin b chain, resulting in the synthesis of abnormal haemoglobin and the consequent production of the characteristic sickled red blood cells. Studies have documented several alterations in lipid homeostasis in this population. Both hyper and hypolipidaemias are known to be associated with increased morbidity and mortality and it is therefore imperative to evaluate their relationships with sickle cell anaemia. Aim: The aim of this study was to establish baseline serum lipid levels in sickle cell anaemia patients in LASUTH and correlate this with severity scores in the patients. Subjects and Methods: Serum Total cholesterol (TC), Triglycerides (TG), Low-density lipoproteins (LDL), High-density lipoproteins (HDL) and Very low-density lipoproteins (VLDL) were measured in 57 Haemoglobin SS (HbSS) patients in steady state.

Y1 - 2016/3/4. N2 - We describe a case of delirium occurring in a hospitalized sickle cell patient. Following admission for a typical pain crisis, the patient continued to report unrelieved pain with marked agitation for several days, despite escalating doses of opioid analgesia, and ultimately required intubation following development of acute chest syndrome (ACS). After some delay, it was discovered that he had been using a synthetic cannabinoid (K2) which may have precipitated his pain crisis and, with hindsight, explained his prolonged period of delirium. Delayed recognition was due to multiple factors, notably the absence of an index of suspicion for this novel drug, the presence of alternate explanations for the patients altered mental status, and the fact that reliable laboratory screening for ...

Nine patients were assigned to inhaled NO (80 ppm) and nine to placebo (21% O2). Primary outcome was the mean change in pain scores ...
Sickle cell anemia is an autosomal recessive disorder and the most common genetic disease affecting African-Americans. Approximately 0.15% of African-Americans are homozygous for sickle cell disease, and 8% have sickle cell trait. Acute pain crisis, acute chest syndrome (ACS), and secondary pulmonary hypertension are common complications of sickle cell anemia. Mortality rates of sickle cell patients with pulmonary hypertension are significantly increased as compared to patients without pulmonary hypertension. Recent studies report up to 40% mortality at 22 months after detection of elevated pulmonary artery pressures in sickle cell patients. Furthermore, pulmonary hypertension is thought to occur in up to 30% of clinic patients with sickle cell anemia.. This study is designed to determine the prevalence and prognosis of secondary pulmonary hypertension in adult patients with sickle cell anemia, and to determine whether genetic polymorphisms in candidate genes contribute to its development or ...
Background and Objective: Inflammatory markers that influence bone pain crisis (BPC) and other complications of sickle cell anaemia (SCA) are numerous and play various roles. This study determined the plasma levels of tumour necrosis factor (TNF) - ?, interleukin - 8 (IL-8), and endothelin - 1 (ET-1) in adult SCA patients during BPC and in steady state. In addition, the plasma levels of these cytokines were correlated with the severity of BPC of the patients.. Methods and Materials: Sixty adult SCA patients (30 during BPC and 30 during steady state) and 30 haemoglobin A controls were enrolled for this cross-sectional study. The severity of BPC was assessed clinically, and questionnaires were filled.

Sickle cell anemia is an inherited disease of the red blood cells. This disease has the highest prevalence in African Americans (approx. 8% of African Americans carry the gene trait). Patients who have this serious disease are known as sickle cell DOMINANT. Those who are carriers for sickle cell disease are known as sickle cell TRAIT. The patients with sickle cell trait do NOT have the problems associated with true sickle cell disease, but could pass the DOMINANT form of the disease to their offspring. Patients with sickle cell disease have an abnormal type of hemoglobin in their red blood cells. Hemoglobin is the molecule inside the red blood cell that allows it to carry oxygen. Sickle cell anemia is a multisystem problem, meaning that it can affect several different systems in the body. Blockage of small blood vessels occurs, resulting in many of the manifestations of sickle cell anemia. Below is a partial list.. ...
The clinical severity of sickle cell disease (SCD) and β-thalassemia, the major hemoglobinopathies which affect millions of patients worldwide, can be ameliorated by increased production of fetal hemoglobin (HbF). To date, genome-wide association studies have uncovered three main loci (BCL11A, HBS1L-Myb, and the HBB cluster) that modulate levels of HbF and together account for upwards of 50% of heritability in different populations. In this study, we sought not only to identify new loci by perfoming a step-wise conditional meta-analysis of HbF in ~3400 SCD patients of Africans ancestry and ~6000 healthy Sardinians, but also to understand the regulatory role of these genetic variations by integrating epigenomic annotations. We discovered an intronic common variant (rs4433524, P=3.8x10-8), which maps to BICC1, a gene that encodes for a protein shown in mouse model to have an impact on polycystic kidney disease. Furthermore, we discovered in the Sardinian cohort a non-synonymous variant (rs558942739)
A new research study has determined that body measurements (anthropometric variables) of children with sickle cell anemia are usually smaller than healthy children.. The research study, Body mass index and other anthropometric variables in children with sickle cell anemia, was published in Pakistan Journal of Medical Sciences.. Sickle cell anemia is a frequently inherited hematological disease among people of African descent and common in Nigeria. Symptoms of the disease are many and include chronic haemolytic anemia, musculoskeletal anomalies, infections and some growth problems.. According the report, abnormal growth occurs often in children with sickle cell anemia with nutrition playing a key role in anthropometric status, illness severity and body composition. For example, energy supply is known to cause a constant disturbance in children with sickle cell anemia which influences body mass index (BMI), which can be due to high metabolic rates, inefficient absorption and raised ...
Sickle cell anemia, also known as Sickle Cell Disease (SCD), is a hereditary disorder of the blood characterized by the formation of abnormal hemoglobin molecules in the red blood cells. Hemoglobin is a protein carried by red blood cells that is responsible for transporting oxygen around the body. Due to the atypical haemoglobin molecules the red blood cells in Sickle Cell Anemia disease are also abnormal and tend to be more rigid and crescent or sickle shaped. Sickle Cell Anemia is characterized by ischemia and infarction which is caused by the sickle-shaped blood cells obstructing blood vessels and restricting blood flow to organs or other tissues of the body. Another main symptom of Sickle Cell disease is Hemolytic anemia which is a deficiency of red blood cells due to overly rapid breakdown of the red sickle cells. Organs most frequently damaged by Sickle Cell Disease are the spleen, bone marrow, liver and kidneys.(3) Lung disease can also pose a serious problems and a complication of this ...

Hello Dr. Keller, Recently at our facility (mid-sized jail), we have been having more difficulty managing some of our Sickle Cell Disease patients. I am looking for input from you and / or your readers regarding strategies for managing Sickle Cell patients. The problem as I see it is this: Sickling can be brought on by stressful and/or uncomfortable conditions; temperature variations, hydration issues, and physical or emotional stressful conditions - ALL of which occur routinely in a jail environment. At my facility, I typically allow for more comfort measures when dealing with my Sickle Cell Disease patients. I give an extra mat and extra blanket for comfort and warmth. I give them a small pitcher to fill with water to encourage good hydration. I start off with Tylenol/Motrin for mild everyday pain. We typically avoid opiates in our facility, but allow for opiate medication when it is believed patients are in moderate discomfort. I keep a close eye on things that would suggest infection - heart ...

Background: Sickle cell anaemia (SCA) is a major problem in Uganda; it is estimated to contribute about 15% of paediatric admissions and 10% mortality in children at Mulago hospital. Fetal haemoglobin (HbF) level is one of the most important factors influencing the clinical course in SCA. Populations with high levels of HbF like those in Saudi Arabia have been described as having a mild clinical course with fewer complications. Disease modifying drugs can induce the Hb F levels and modify the presentation of SCA. However, in Uganda, there is no documentation on HbF levels and the correlation to clinical features and disease severity in patients with SCA. Objective: The aims of this study were to document fetal haemoglobin levels and describe the correlation between these levels and disease severity in patients with SCA in Mulago Hospital. Design: This study had two designs: a cross sectional survey to document fetal haemoglobin levels in children with SCA attending Mulago hospital and a ...

Of a cohort of 308 children with homozygous sickle cell disease diagnosed at birth, 89 experienced 132 clinically significant attacks of acute splenic sequestration (ASS) over a 10-year period. The age at first attack ranged from 3 months to 6 years. Survival curve analysis of the interval until first attack indicated a cumulative probability of 0.225 by 2 years, and 0.265 by 3 years, and 0.297 by 5 years of age. Thirteen events were fatal, 11 during the first attack, and all before transfusion could be instituted. Recurrences occurred in 49% of survivors of the first attacks, and there were diminishing intervals between subsequent events. Respiratory symptoms were associated with 52 of 132 events, but bacterial isolates on blood culture were less frequent, and ASS was not prevented by pneumococcal vaccine or penicillin prophylaxis. A high fetal hemoglobin level protected against attacks of ASS. A parental education program aimed at early diagnosis of ASS was followed by an increase in the incidence

Patients with sickle cell disease need certain treatment and follow-up even when not having a painful crisis. Supplementation with folic acid , an essential element in producing cells, is required because of the rapid red blood cell turnover. Bone marrow transplants are currently the only potential cure for sickle cell anemia. In this treatment the patients bone marrow (which makes the sickled red blood cells) is replaced with bone marrow from another individual without sickle cell disease. However, it is difficult to find the right bone marrow donor, and the drugs needed to make the transplant possible are highly toxic. During a sickle crisis, certain therapies may be necessary. Gene therapy (replacing the Hemoglobin S with a normal Hemoglobin A) may be the ideal treatment, but it has proven to be very difficult in humans Pain management. Pain is a common problem with sickle cell anemia. Some patients get the relief they need from over-the-counter medication,. Others need stronger painkillers. ...
The National Heart, Lung, and Blood Institute (NHLBI) announced today a treatment that reduces the rate of stroke (cerebral infarction) in children with sickle cell anemia. Strokes occur in approximately 10% of children with sickle cell anemia. These events can be very debilitating, leading to physical and neuro-psychological impairment which can affect motor skills, school performance, and overall quality of life. The treatment, periodic red blood cell transfusions to maintain the level of hemoglobin S (HbS) below 30%, reduced the rate of cerebral infarction by 90% in children found to be at increased risk by virtue of having elevated transcranial doppler velocities.. The Stroke Prevention Trial in Sickle Cell Anemia (STOP) proposed to reduce first-time stroke in children with sickle cell anemia by 70% by the administration of prophylactic transfusion therapy. The study design was based on the clinical observation that if hemoglobin S (HbS) levels are maintained at or below 30% in children who ...
Sickle cell anemia develops when a person inherits defective sickle beta-globin genes from their parents, causing them to produce abnormal hemoglobin. The cells are abnormally shaped, which makes it difficult for them to travel through blood vessels. Sickle-shaped red blood cells are more fragile, causing them to break or become lodged, which can block blood flow or reduce the bodys oxygen supply. Sickle cell anemia symptoms include weakness, shortness of breath and chest pains. (1) While sickle cell anemia causes cannot be prevented, natural sickle cell anemia treatment can help manage symptoms.. ...
Background: Hydroxyurea is an antimetabolite that minimizes pain and prolongs survival in patients with sickle cell anemia (1). It is not widely prescribed because of concerns about late effects, including cancer (2), and its leukemogenic risk is extrapolated from its reported risk in myeloproliferative disorders (3). Few cases of leukemia in patients with sickle cell anemia have been described, and only half of them report cytogenetics (4). Acute myelogenous leukemia (AML) in patients with sickle cell anemia receiving hydroxyurea treatment is exceptionally rare, but data on its true incidence are insufficient (1, 2). Whether AML in hydroxyurea-treated patients with sickle cell anemia is coincidental or related to therapy remains an unanswered question (2) ...
A stem cell transplant, also called a bone marrow transplant, includes changing bone marrow affected by sickle cell anemia with healthy bone marrow from a donor. Since of the risks connected with a stem cell transplant, the procedure is suggested only for individuals who have considerable symptoms and problems from sickle cell anemia.. If a donor is found, the infected bone marrow in the individual with sickle cell anemia wases initially diminished with radiation or chemotherapy. Healthy stem cells from the donor are filtered from the blood.. The healthy stem cells are injected intravenously into the bloodstream of the person with sickle cell anemia, where they migrate to the bone marrow cavities and begin generating new members cells. The procedure needs a prolonged hospital stay. After the transplant, youll get drugs to assist avoid rejection of the contributed stem cells.. A stem cell transplant brings risks. Theres a possibility that your body may decline the transplant, resulting in ...
What is sickle cell anemia disease?Anatomy and Pathophysiology of Sickle Cell Anemia.The Mechanism for the Chronic Pain of Sickle Cell Anemia.Treatment for Sickle Cell Anemia.
INTRODUCTION. Sickle cell anemia is a genetic disorder characterized by a mutant type of hemoglobin, called hemoglobin S (HbS), that causes the sickling of red blood cells.1 Sickle cell anemia is the most common hereditary disease in Brazil and worldwide.2-5 In Brazil, it is estimated that more than two million people carry the gene for HbS, and over 8,000 individuals have the severe form (SS). Approximately 700,000 new cases of sickle-cell disease occur annually.6 The disease is prevalent among African descendents.6,7. Sickle cell anemia, although treatable, is a chronic incurable disease involving medical, dental, genetic, and psychosocial factors.7,8 Dentists play an important role in preventing complications and improving the quality of life of patients with sickle cell disease9 because these patients are more susceptible to infections and periodontal disease.10 These patients are also at a higher risk of developing dental caries because of the high prevalence of dental opacities (changes in ...

Atrium Health Navicent Beverly Knight Olson Childrens Hospital Honors Sickle Cell Patients. September is National Sickle Cell Awareness Month MACON, GA (Wednesday, September 24, 2014) - Atrium Health Navicent Beverly Knight Olson Childrens Hospital will honor brave young patients who live with sickle cell anemia during September, National Sickle Cell Awareness Month, by raising awareness of this genetic disease.. Sickle cell anemia is an inherited form of anemia, a condition caused when the body does not produce enough healthy red blood cells to adequately carry oxygen throughout the body. Red blood cells are normally round and flexible, easily moving through the bodys blood vessels. For patients with sickle cell anemia, however, red blood cells become rigid, sticky and shaped like crescent moons. The irregular cells may become stuck in small blood vessels, which may slow or block blood flow and oxygen to various parts of the body. Symptoms of the condition include anemia, episodes of pain, ...
What is the main genetic abnormality in sickle cell disease? Describe why patients with sickle cell disease are at risk of vascular crises.. Sickle cell disease includes all conditions associated with hemolytic anemia and vaso-occlusive pain. Over 20% of people in equatorial Africa are heterozygous for the sickle gene, as it is believed to offer protection against malaria. The pathophysiology arises from an amino acid switch in the 6th position (11th chromosome) from glutamic acid to valine.. When hemoglobin S encounters a deoxygenated state, the hemoglobin is less soluble and the Hb S tetramers aggregate or polymerize. The sickled RBCs adhere to the vascular surface, causing occlusion and an increased hypercoagulable state.. Not surprisingly, sickle cell disease patients have the potential for many co-morbidities:. ...
Vaso-occlusive crisis-sickle cell pain related crisis-is the primary cause for hospital visits for sickle cell patients. Although the etiology of vaso-occlusion is not well understood, increased expression of P-selectin in endothelial cells and platelets contributes to the pathogenesis. Crizanlizumab, a monoclonal antibody directed toward P-selection, blocks its interaction with other cells and may reduce the risk of sickle cell pain crises. In a phase-2, multi-center, placebo-controlled trial, 198 patients were randomized in a 1:1:1 ratio to receive either high dose crizanlizumab (5.0 mg per kg of body weight), low dose crizanlizumab (2.5 mg per kg) or a placebo drug during the one year study. Patients with sickle cell disease who were taking high doses of crizanlizumab had a median rate of 1.63 pain crises compared to 2.98 among those taking the placebo (45.3% lower rate, P=0.01). Furthermore, the median time to first crisis was longer for patients taking high dose crizanlizumab, and these ...

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.. ...

In Northern Nigeria with a population of 90 million there are 30 Million Sickle Cell Traits. One in every three babies born there in Kano, Sokoto, Maedeguru is Sickle Cell Trait. And in Accra where I worked at the Korle Bu Teaching Hospital every 1 in 5 babies of the 13000 consecutive deliveries we tested in 12 months had Sickle Cell Trait.. What is more, 1 in every 3 of the white people in Greece where Lake Kopais used to be is Sickle Cell Trait! And now, lo and behold, In Fontana August is Sickle Cell Trait Prevention Month. Are they serious in suggesting Sickle Cell Trait needs preventing? Making 1 in 5 of us Ghanaians feel guilty for being ...
Sickle Cell Anemia is the most common inherited blood disorder in the United States, affecting 1 in 375 to 500 African Americans. Eight percent of African Americans are affected. Homozygous HbS disease occurs in 0.2% of African Americans, while heterozygous sickle cell trait occurs in 8%. Globally, a quarter of a million children are born every year with the disease. At least five haplotypes of sickle cell disease are recognized based upon their origin: Senegal, Cameron, Benin, Central African Republic, and India. Among these, patients from the Central African Republic have the most severe disease and those from Senegal the least severe. Other nationalities with sickle cell include Arabs, Greeks, Italians (mostly southern), and Latin Americans. ...
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. ...
Sickle cell anemia patients suffer from oxidative stress due to chronic inflammation and self-oxidation of sickle hemoglobin (Hb S). Chronic oxidative stress contributes to endothelial dysfunction, inflammation and multiple organ damage in sickle cell disease (SCD). Thus, antioxidant medication may favorably influence the disease. Gum Arabic (GA), edible, dried, gummy exudates from Acacia Senegal tree, has been claimed to act as an anti-oxidant and cytoprotective agent, protecting against experimental hepatic, renal and cardiac toxicities in rats. We hypothesized that regular intake of GA increases anti-oxidant capacity and reduce oxidative stress. Forty-seven patients (5-42 years) carrying hemoglobin SS were recruited. Patients received 30 g/day GA for 12 weeks. Total anti-oxidant capacity (TAC), malondialdehyde (MDA) and hydrogen peroxide (H2O2) levels were measured by spectrophotometric methods before and after GA intake. Complete blood count was measured by sysmex. Gum Arabic significantly increased

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. ...
Background. Hemoglobin SC disease is one of the most frequent hemoglobinopathy. Surprisingly, few studies were dedicated to this disease, currently considered as a mild variant of homozygous sickle cell disease. The aim of this study was to update our knowledge about hemoglobin SC disease. Design and Methods. We conducted this study in a monocentric series of 179 patients. Clinical and biological data were collected, with a special concern for the assessment of pulmonary arterial hypertension and nephropathy. Results. Hemoglobin SC diagnosis was delayed and performed in adulthood in 29% of cases. Hospitalized painful vasoocclusive crisis, acute chest syndrome and priapism had a prevalence of 36%, 20% and 20% respectively. The most common chronic organ complications were retinopathy and sensorineural otologic disorders occurring in 70% and 29% of cases. Indeed, prevalence of complications reported in homozygous sickle cell disease such as nephropathy, suspicion of pulmonary hypertension, strokes ...
Dr. Rodger McEver and his teams at the Oklahoma Medical Research Foundation and Selexys did not set out to create a drug that could be used by sickle cell disease patients.. Rather, McEver was studying a protein thats connected to white blood cells.. He had been studying that protein, call P-selectin, since the 1980s when he worked at the University of Texas in San Antonio. P-selectin is a protein thats expressed on the surface of blood platelets that are involved in blood clotting, as well as on cells that line blood vessels. P-selectin only goes to the surface of cells when activated, which happens as a response to an injury, infection or bleeding.. When he moved to Oklahoma City in 1987, he and other researchers dug more into P-selectin.. We thought this protein we discovered was likely to do something important because it was an early sentinel, he said. It got popped to the surface when you needed a protective response or had an infection.. Read the story on VeloCityOKC.com. ...
Review question We reviewed the effectiveness of blood transfusions, simple and exchange, for treating acute chest syndrome by comparing improvement in symptoms and clinical outcomes against standard care. This is an update of a Cochrane review first published in 2010.. Background Sickle cell disease is an inherited blood condition affecting over 250 million people worldwide and is particularly common in Sub-Saharan Africa, South and Central America, Saudi Arabia, India and a number of Mediterranean countries. It is characterised by the presence of sickle-shaped red blood cells which are capable of blocking the blood vessels causing pain and severe damage to several organs of the body. People with sickle cell disease may have the acute onset of chest problems which may include fever, this is called acute chest syndrome. It may have several different causes which include infection and blockage of blood vessels. Fever, coughing, shortness of breath which are accompanied with chest pain are the ...

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 ...

In the resting state, capillary red cell (rbc) flux exhibited greater intermittence compared with normal subjects, which increased with painful crisis. In crisis-free HbSS subjects, capillary occlusion and red cell sequestration occurred in only 8.2% of all capillaries and diminished to 5.8% during crisis, possibly due to sequestration of less deformable rbcs in other organs. Velocities of rbcs (V(rbc)) were measured by video techniques under resting conditions and during postocclusive reactive hyperemia (PORH) induced by a pressure cuff around the finger. Resting V(rbc) was normal in crisis-free HbSS subjects, ...
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 ...
AIM--This study was set up to determine whether or not retinal changes occur in sickle cell disease in Saudi Arabian subjects with either the Benin, which exists in the south western part of the kingdom, or Asian haplotypes in the east, and to compare the findings with those in sickle cell disease in Jamaica. METHODS--Retinal examination and fluorescein angiography were performed in 61 patients with SS disease (40 eastern, 20 south western, 1 central region) and 10 with sickle cell beta(0) thalassaemia. RESULTS--Peripheral retinal vascular changes were common, and a qualitatively abnormal vascular border believed to imply risk of proliferative sickle retinography (PSR) was significantly more common in south western SS patients and PSR was shown in one of these. There were no differences in visual acuity, the presence of peripheral retinal patches, or the circumferential or posterior extent of peripheral retinal vessel closure between SS disease and sickle cell beta(0) thalassaemia or between SS ...
Sickle Cell Disease (SCD) is an autosomal recessive inherited condition characterized by the inheritance of two abnormal genes coding for the formation of Haemoglobin and one of them is Haemoglobin s. Musculoskeletal manifestations are the commonest clinical presentations of both acute and chronic cases of vaso-occlusive crisis (VOC). According to the Surgical department (of the University Teaching Hospital, Lusaka) audits done in the last 3 years, patients with SCD have been presenting very late with advanced musculoskeletal manifestations. The objective of this study was to explore the potential predictors of Musculoskeletal Manifestations in Paediatric patients presenting with Sickle Cell Disease seen at the University Teaching Hospital, Lusaka. The specific objectives were: To determine the commonest musculoskeletal manifestations in paediatric patients presenting with Sickle Cell Disease seen at University Teaching Hospital; then to determine the socio-demographic factors associated with ...
Peculiar elongated and sickle-shaped is how sickle cells were first described in 1904 by intern Ernest Edward Irons when examining the blood of Walter Clement Noel, a 20-year-old first-year dental student from a wealthy Black family in Grenada. Noel had been admitted to the Chicago Presbyterian Hospital suffering from anemia and was readmitted several times over the next three years before completing his studies and returning to Grenada to successfully practice dentistry. He died of pneumonia in 1916.. Irons supervising physician, James B. Herrick, wrote a paper published in 1910 in the Archives of Internal Medicine documenting the first known case of sickle cell disease in the United States. (Source: https://www.sicklecellnewjersey.org/). Sickle cell disease mainly affects people of African, Caribbean, Middle Eastern, Eastern Mediterranean and Asian origin. In the UK, its particularly common in people with an African or Caribbean family background.. People with sickle cell disease produce ...

HbSC disease causes symptoms similar to those of homozygous (SS) sickle cell anemia (SCA) such as vaso-occlusive episodes and organ damage [2] with milder severity and less frequency [2,6,13]. Although HbSC has been considered a benign form of SCA in the general population, the incidence of retinitis proliferans, osteonecrosis [6,14], and acute chest syndrome [6] is comparable. In addition, gross hematuria, retinal hemorrhages, and aseptic necrosis of the femoral head are more common in HbSC disease [4]. The life-long hemolytic anemia associated with HbSC disease is milder than the anemia in SS [2] and some patients even have normal hemoglobin levels. This is evidenced by the red cell life-span being approximately two-fold higher in HbSC than in SCA patients (28.9 days vs 15 days, respectively) [15,16]. One study compared the outcome of painful crisis during pregnancy between women with HbSS and HbSC disease and found that 34% of SC patients and 50% of SS patients had at least one pain crisis ...

BACKGROUND: Sickle cell disease (SCD) is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. SCD can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Silent cerebral infarcts are the commonest neurological complication in children and probably adults with SCD. Silent cerebral infarcts also affect academic performance, increase cognitive deficits and may lower intelligence quotient. OBJECTIVES: To assess the effectiveness of interventions to reduce or prevent silent cerebral infarcts in people with SCD. SEARCH METHODS: We searched for relevant trials in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 19 September 2016. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register: 06 October 2016. SELECTION CRITERIA: Randomised controlled
Sickle cell disease is a highly prevalent disease in the United States, affecting 1 in 500 African American infants. It is common in individuals of African, Caribbean, Mediterranean, Arab, and other Middle Eastern descent. It is a genetic disorder with an autosomal recessive inheritance pattern. Sickle cell disease is often called the first molecular disease because the biochemical alteration in sickle hemoglobin described by Linus Pauling in 1948 was one of the first lesions identified at the molecular level for a human disease. Sickle hemoglobin forms rod-like polymers in deoxygenated red cells in areas of the circulation, with low oxygen tension, acidosis, or hyperosmolarity. Sickle hemoglobin polymerization causes a host of secondary molecular and cellular changes, many of which impair blood flow and contribute to tissue damage. The microcirculation can be acutely or chronically impaired in virtually any organ in the body, resulting in the characteristic crisis pattern of intermittent pain ...

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:. ...

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.

Background: Recent studies suggest that patients with sickle cell disease (SCD) have profound vitamin D deficiency (VDD). Moreover, lower levels of vitamin D can affect thyroid function which in turn affects bone formation. Aim: To determine the prevalence of VDD in patients with homozygous SCD and to evaluate the predictors of VDD in them. Method: Relevant data was retrieved from hospital database. Pearsons correlation and Multiple linear regression analysis was performed on these data to assess VDD in patients with SCD. Results: The vitamin D level was remarkably lowered in SCD patients (mean 19.1±14.7 nmol/L vs. 75.9±33.5 nmol/L) when compared to controls (p,0.05). SCD patients had increased ALP levels (161.3±68.0 vs. 61.7±16.6, p,0.001), reticulocyte count (4.18±2.7 vs. 1.07±0.68, p,0.01) and reduced levels of TSH (1.05±0.91 vs. 1.74±1.0, p,0.05). No difference existed between patients of different age groups or gender. Conclusion: A general VDD prevailed in Kuwaiti population but ...
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.

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 ...
