Abstract:
Sickle cell disease was first described by Herrick in 1910. This disease involves an abnormality of the hemoglobin molecule which, under certain conditions, causes the red cell to take on a sickle shape. This abnormal shape and hemoglobin prevent the red cell from performing the normal respiratory functions and interfere with the normal flow through the circulatory system. Individuals demonstrate either a homozygous (dominant) SS or a heterozygous Ss state. Clinical symptoms for patients with SS disease are most often characterized by recurrent painful crises, sequestration of sickled cells, c

Malaria, according to encyclopedia Britannica, is a relapsing infection caused by plasmodium, transmitted to humans through the bite of an anopheles mosquito. The composition of the genes in humans can either be homozygous (AA, SS) or heterozygous (AS), the homozygous are usually prone to the infection of malaria. The homozygous sickle cell genes (SS) encounter serious problems with blood shortage due to the sickle cell, this makes the malaria infection in them more complicated.

Abstract:
Abstract In humans, genetic mutations have led to the formation of several haemoglobin (Hb) variants during human evolution. These mutations usually occur in the genes for a and Β- polypeptide or globin chains of haemoglobin located on chromosomes 11 and 16, respectively. Among these haemoglobin variants, sickle cell haemoglobin (Hb-S) is highly significant in the humans. In fact, this abnormal or mutant haemoglobin is the resultant of a point mutation in the gene for Β-globin, located on chromosome 11. No doubt, this sickle cell gene is relatively more prevalent among tribal people

Sickle cell disease (SCD), the most commonly inherited hemoglobinopathy, can result in vision loss due to sickle cell retinopathy (SCR), vascular occlusions, and retinal atrophy. SCR is more common in heterozygous (HbSc) than homozygous (HbSS) patients. HbD (Punjab) is a less commonly reported form of hemoglobin in SCD, seen in northwestern states of India. Patients with sickle cell hemoglobin D disease (HbSD) can clinically behave like HbSS. We report a case of asymmetric SCR and multiple branch retinal artery occlusions in a patient with sickle cell hemoglobin D disease in central India.

Abstract:
Sickle cell disease (SCD) results in alteration of both hematological and biochemical parameters of the affected individuals. In Kenya, it is estimated that 4,000 children are born with SCD annually; about 21% of children in Kisumu are born with Sickle cell trait. Study objective was to analyze the screening of SCD using various screening techniques at German Doctors-Baraka Health Center in Mathare, Nairobi. On methodology, purposive sampling and cross sectional study design was employed among patients of all ages with clinical features suggestive of SCD. Data utilization permission was sought

Abstract:
Introduction: Homozygous sickle cell disease is characterized by chronic anemia which contributes to a clinical course characterized by recurrent pain crisis episodes. These episodes are usually managed with the use of packed red blood cell products. Randomized data is currently available that supports lower transfusion thresholds in non-sickle cell related conditions including but not limited to patients undergoing orthopedic procedures, cardio-vascular interventions and those needing intensive care. Due to lack of similar randomized trials in patients with sickle cell disease, recommendation

Abstract:
Sickle cell disease is an autosomal recessive genetic disorder and one of the most common haemoglobinopathies in Morocco. It is characterised by the polymerisation of haemoglobin S, resulting in a change in the spatial conformation of sickle cell haemoglobin, and consequently in its function. Hydroxyurea is the only product with proven efficacy in preventing the complications of sickle cell anaemia and has been approved by the "Food and Drug Administration". The effects of hydroxyurea are essentially linked to the increase in HbF by inhibiting the polymerisation of haemoglobin S, which is the

Abstract:
Sickle cell disease (SCD) is a genetic disorder caused by a missense mutation in the beta-globin gene [Glu6Val] resulting in the formation of HbS (sickle hemoglobin). HbS polymerizes under low oxygen tension causing an array of severe pathophysiological complications, including vaso-occlusion, pain and hemolytic anemia. Traditionally, research efforts toward studying anti-sickling effects of various pathways and compounds in vitro have been made using sickle cell patient derived samples. However, such studies are limited based on sample availability and a large degree of phenotypic variability

Background. This study sought to identify the pattern of electrocardiographic changes in steady state adult sickle cell anaemia.Methods.A case-control, cross-sectional study was conducted amongst sickle cell patients attending the sickle cell clinic of Lagos State University Teaching Hospital, Ikeja, and HbAA controls. All consenting participants had haemoglobin electrophoresis done and were subjected to electrocardiography (ECG). The descriptive data were given as means ± standard deviation (SD). The differences were considered to be statistically significant when thepvalue obtained was &lt;0

SummaryPlatelet and vascular endothelial prostaglandin derivatives were measured by radioimmunoassay in the plasma of 39 children with homozygous sickle cell anaemia and 27 control subjects. The levels of both thromboxane B2 and 6-keto-PGF1α, the stable endproducts of platelet and vascular prostaglandin metabolism, were significantly (p &lt;0.001) greater in sickle cell anaemia plasma than in the plasma of the controls. There were no differences in levels of either 6-keto-PGF1α or thromboxane B2 between steady state and vaso-occlusive crisis in the sickle cell patients. Injury to the endotheli
