OBJECTIVE: Hemochromatosis is an autosomal recessive disease which is one of the most important reasons of iron overload. Sickle cell disease is a hemoglobinopathy which occurs as a result of a homozygote mutation in the hemoglobin gene. Erythrocyte transfusion is frequently used in treatment of this disease. Iron overload as a result of transfusion is important in mortality and morbidity of sickle cell anemia patients as well as in other hemoglobinopathies. In this study, the effect of HFE gene p...

Haemoglobinopathies particularly haemoglobin S and E (HbS, HbE) and β-thalassaemia are important challenges for tribal populations in India. The HbS, HbE and β-thalassaemia genes are variably distributed across various tribal populations of India. HbE is mainly restricted in tribals of North-East, West Bengal, Odisha and those in Andaman and Nicobar islands. HbS has more extensive distribution in the country (10-40% trait frequency) and the homozygotes and double heterozygotes present with a wide array of morbidities...

Worldwide, sickle cell trait is a highly prevalent gene carrier state. While generally a benign condition with a normal life expectancy, it is becoming increasingly clear that the sickle trait is associated with certain adverse outcomes. This article will focus on three of these outcomes, namely exertional rhabdomyolysis and sudden death, chronic renal dysfunction, and venous thromboembolism. In each case, the epidemiological evidence for the association is reviewed, together with the existing data on potential underlying mechanisms...

BACKGROUND: Haemoglobinopathies, inherited disorders of haemoglobin synthesis (thalassaemia) or structure (sickle cell disease), are responsible for significant morbidity and mortality throughout the world. The WHO estimates that, globally, 5% of adults are carriers of a haemoglobin condition, 2.9% are carriers of thalassaemia and 2.3% are carriers of sickle cell disease. Carriers are found worldwide as a result of migration of various ethnic groups to different regions of the world. Zinc is an easily available supplement and intervention programs have been carried out to prevent deficiency in people with thalassaemia or sickle cell anaemia...

Sickle cell anaemia (SCA) is a severe debilitating haematological disorder associated with a high degree of morbidity and mortality. The level of fetal haemoglobin (HbF) is well-recognized as a critical laboratory parameter: lower HbF is associated with a higher risk of vaso-occlusive complications, organ damage, and early death. Hydroxycarbamide treatment can induce HbF, improve laboratory parameters, and ameliorate clinical complications of SCA but its mechanisms of action remain incompletely defined and the HbF response is highly variable...

Severe malarial anemia (SMA) is a leading cause of morbidity and mortality in children residing in regions where Plasmodium falciparum transmission is holoendemic. Although largely unexplored in children with SMA, interleukin-18 (IL-18) is important for regulating innate and acquired immunity in inflammatory and infectious diseases. As such, we selected two functional single-nucleotide polymorphisms (SNPs) in the IL-18 promoter (-137G→C [rs187238] and -607C→A [rs1946518]) whose haplotypes encompass significant genetic variation due to the presence of strong linkage disequilibrium among these variants...

Transfusional iron overload is a major cause of morbidity and mortality in thalassemia, sickle-cell disease and other chronic anemias. To overcome these problems, orally bio available iron chelators, deferiprone and deferasirox, were used for the treatment of patients suffering from thalassemia. The interactions between deferiprone and deferasirox with the carrier protein, beta-thalassemia hemoglobin (Hb), were investigated using fluorescence, circular dichroism (CD) and UV-visible measurements at physiological condition...

Sickle cell trait occurs in approximately 300 million people worldwide, with the highest prevalence of approximately 30% to 40% in sub-Saharan Africa. Long considered a benign carrier state with relative protection against severe malaria, sickle cell trait occasionally can be associated with significant morbidity and mortality. Sickle cell trait is exclusively associated with rare but often fatal renal medullary cancer. Current cumulative evidence is convincing for associations with hematuria, renal papillary necrosis, hyposthenuria, splenic infarction, exertional rhabdomyolysis, and exercise-related sudden death...

Neonatal screening for haemoglobinopathies started in The Netherlands on 1 January 2007. The method of choice, high-performance liquid chromatography, and the universal setting have shown that the predicted incidence is indeed present in the country. Patients and carriers are reported in order to prevent morbidity, and for the primary prevention of serious haemoglobinopathies. Background, preceding discussion, health gain, implementation, provisional results and ethics issues are discussed, as well as matters concerning technology, know-how, and ongoing and future developments...

Sickle cell disease (SCD) is a debilitating monogenic blood disorder with a highly variable phenotype characterized by severe pain crises, acute clinical events, and early mortality. Interindividual variation in fetal hemoglobin (HbF) expression is a known and potentially heritable modifier of SCD severity. High HbF levels are correlated with reduced morbidity and mortality. Common single nucleotide polymorphisms (SNPs) at the BCL11A and HBS1L-MYB loci have been implicated previously in HbF level variation in nonanemic European populations...

BACKGROUND AND OBJECTIVE: Prevalence of hemoglobinophaty S and glucose-6-phosphate dehydrogenase (G6PD) deficiency are very increased in certain zones of Western Africa due to the positive pressure exerted by malaria on these congenital defects. In Maresme, a region of East Catalonia, there is a numerous community of African people, coming from areas of Western Africa where sickle cell trait and G6PD deficiency are frequent. The aim of our study was to know the prevalence of both disturbances in this population...

BACKGROUND: Erythrocyte transfusion decreases morbidity in sickle cell disease, but is not without risk. Use of a hemoglobin-based oxygen carrier could offer the benefits of erythrocyte transfusion while reducing related complications. The authors tested the hypothesis that the novel hemoglobin-based oxygen carrier, HRC 101, would improve survival during exposure to acute hypoxia in a murine model of sickle cell disease, the transgenic mouse expressing hemoglobin SAD (alpha2beta2). METHODS: Wild-type (n = 30) and transgenic SAD (n = 36) mice received 0...

BACKGROUND: Sickle cell anemia is a hereditary disease which, as a result of migration, constitutes one of the most frequent genetic disorders in northwest Europe. Complications secondary to this disease are common during the first 3 years of life and early diagnosis has been recommended to reduce their development. The autonomous community of Madrid began to perform universal neonatal screening for hemoglobinopathies in May 2003. This study presents the results of the first 32 months of this screening program...

UNLABELLED: Seventy-two thousand Americans are homozygous for the sickle cell gene and 2 million are carriers. The gene offers protection against malaria but can be a cause of chronic pain and early death. Life expectancy is 48 years for females. Some people with sickle cell anemia live into their 60s and beyond. The purpose of this article is to review and summarize evidence from clinical, translational, and epidemiologic studies that have examined the clinically relevant aspects of sickle cell anemia as it relates to the female patient...

Sickle cell disease and G6PD deficiency have similar prevalence of 8 to 10% in Senegalese population. Our objectives were to determine the prevalence of G6PD deficiency in Hb S carriers and normal subjects, and to assess the interaction of G6PD deficiency on clinical severity of sickle cell disease. G6PD activity was measured in 319 sickle cell patients and in 318 subjects without HbS. Clinical severity was compared in male homozygous sickle cell patients (11 with G6PD deficiency and 19 without deficit). In homozygous sickle cell patients, the G6PD status was assessed after correction of reticulocyte count following the micro-centrifugation method of Herz...

Homozygous sickle cell disease (SCD) has a wide spectrum of clinical manifestations. In Brazil, the main cause of death of individuals with SCD is recurrent infection. The CCR5delta32 allele, which confers relative resistance to macrophage-tropic HIV virus infection, probably has reached its frequency and world distribution due to other pathogens that target macrophage in European populations. In the present investigation a relatively higher prevalence (5.1%) of the CCR5delta32 allele was identified, by PCR amplification using specific primers, in 79 SCD patients when compared to healthy controls (1...

Plasmodium ovale is a common malaria parasite in Africa, but the epidemiology of P. ovale malaria is poorly known. Exposure to malaria, parasitemia, and morbidity were monitored for 6 years among the residents of a village in Senegal. The relationship between the level of P. ovale parasitemia and fever risk were analyzed, and diagnostic criteria for clinical P. ovale malaria were established. Then the relationships between the occurrence of P. ovale clinical malaria and a series of entomological, epidemiological, and genetic factors were investigated...

Sickle cell disease is caused by a variant of the beta-globin gene called sickle hemoglobin (Hb S). Inherited autosomal recessively, either two copies of Hb S or one copy of Hb S plus another beta-globin variant (such as Hb C) are required for disease expression. Hb S carriers are protected from malaria infection, and this protection probably led to the high frequency of Hb S in individuals of African and Mediterranean ancestry. Despite this advantage, individuals with sickle cell disease exhibit significant morbidity and mortality...

By its frequency, but also by its morbidity and mortality, sickle cell disease is a real problem of public health in Senegal. It is an inherited disease of the red blood cell, characterized by vaso-occlusive manifestations in several organs, and chronic hemolytic anemia. Out of this work carried upon subjects presenting sickle cell trait (AS), we especially studied the membrane phospholipids. The aims of this study was to identify and to measure the major phospholipids of the red blood cell membrane (lecithin, lysolecithin, cephalin, lysocephalin and sphingomyelin)...

Sickle cell trait is a benign genetic abnormality which has been wrongly projected as a health hazard in aviation. Conflicting reports on the relationship between this trait and flying exist in the literature. Limitations placed on sickle trait individuals unfairly stigmatize large numbers of people, both socially and economically. The imprecise identification of the sickle hemoglobinopathies and unrecognized interactions of other abnormal hemoglobins with hemoglobin S have perpetuated the controversy. There is a tendency to use isolated anecdotal incidents as evidence of increased morbidity in sickle cell trait; however, it has not been documented that hypoxic conditions cause in vivo sickling in pure trait carriers...
