Prevalence of sicklecelltrait and needs assessment for uptake of sickle cell screening among secondary school students in Kampala City, Uganda. Sickle cell disease (SCD) is one of the most frequent and traumatizing genetic disease in Uganda, with the prevalence of the sicklecelltrait (SCT) estimated at 13.3% leading to serious psycho-social and economic impact on the patients
Statistical exploration of factors associated with birth of children having sicklecelltraits among reproductive-age women in Nigeria. Despite the relatively high prevalence of Sicklecelltrait (SCT) in Nigeria, there has been little research into the correlates of having children with SCT among Nigerian mothers, particularly in terms of socio-demographic differentials. This study aims
Sicklecelltrait in São Tomé e Príncipe: a population-based prevalence study in women of reproductive age. Sickle Cell Disorder is Africa's most prevalent genetic disease. Yet, it remains a neglected condition, with high mortality under-five, and a lack of population-based studies in the region. This is the first of its kind in São Tomé e Príncipe, aiming to estimate the prevalence of sicklecelltrait and other haemoglobin variants in women of reproductive age and its associated factors. We conducted a cluster survey in 35 neighbourhoods. Haemoglobin was assessed through point-of-care capillary electrophoresis or high-performance liquid chromatography, and sociodemographic data through questionnaires. The weighted prevalence of sicklecelltrait (HbAS) and HbC carriers was estimated
Delayed Plasmodium falciparum Malaria in Pregnant Patient with SickleCellTrait 11 Years after Exposure, Oregon, USA. Delayed Plasmodium falciparum malaria in immigrants from disease-endemic countries is rare. Such cases pose a challenge for public health because mosquitoborne transmission must be rigorously investigated. We report a case of delayed P. falciparum malaria in a pregnant woman with sicklecelltrait 11 years after immigration to the United States.
Blood count changes in malaria patients according to blood groups (ABO/Rh) and sicklecelltrait. Introduction: Malaria continues to be the leading cause of hospitalization and death in Angola, a country in sub- Saharan Africa. In 2023, in the first quarter, 2,744,682 cases were registered, and of these 2,673 patients died due to malaria disease. Previous studies have shown that the ABO blood group can affect the progression of malaria to severe conditions after P. falciparum infection, while the sickle cell gene offers relative protection. We investigated changes in the blood count according to blood groups (ABO/Rh) and sicklecelltrait in patients with malaria in Luanda, capital of Angola. This was a longitudinal, prospective and observational study with 198 patients hospitalized
SickleCellTrait PRACTICE GUIDE FOR SICKLECELLTRAIT IDENTIFIED IN NEWBORN SCREENING | April 2019 These recommendations are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances. They should be used as an adjunct to sound clinical decision making. OBJECTIVE To provide guidance to health care providers when they receive notification a newborn in their care is a sicklecelltrait carrier. Providers will be responsible for communicating results with the family and arranging necessary follow-up in accordance with this guide. TARGET POPULATION Infants born
Influence of the sicklecelltrait on Plasmodium falciparum infectivity from naturally infected gametocyte carriers. Sicklecelltrait (SCT) refers to the carriage of one abnormal copy of the β-globin gene, the HbS allele. SCT offers protection against malaria, controlling parasite density and preventing progression to symptomatic malaria. However, it remains unclear whether SCT also affects
Association of sicklecelltrait with adverse pregnancy outcomes in a population-based cohort. Sicklecelltrait (SCT) is common in African descendants. Its association with several adverse pregnancy outcomes (APOs) has been reported but remains inconsistent. The objectives of this study are to test associations of SCT with APOs in non-Hispanic Black women, including (1) validate
Differences in the Circulating Proteome in Individuals with versus without SickleCellTrait. Sicklecelltrait affects ∼ 8% of African American individuals, along with many other individuals with ancestry from malaria-endemic regions worldwide. While traditionally considered a benign condition, recent evidence suggests sicklecelltrait is associated with lower eGFR and higher risk of kidney diseases, including end-stage kidney disease. The mechanisms underlying these associations remain poorly understood. We utilized proteomic profiling to gain insight into the pathobiology of sicklecelltrait. We measured proteomics (N=1,285 proteins assayed by Olink Explore) using baseline plasma samples from 592 African American participants with sicklecelltrait and 1:1 age-matched African American
Silent Infarcts, White Matter Integrity, and Oxygen Metabolic Stress in Young Adults With and Without SickleCellTrait. Individuals with sickle cell anemia have heightened risk of stroke and cognitive dysfunction. Given its high prevalence globally, whether sicklecelltrait (SCT) is a risk factor for neurological injury has been of interest; however, data have been limited. We hypothesized
Strenuous exercise in warm environment is associated with improved microvascular function in sicklecelltrait. Sicklecelltrait is characterized by the presence of both normal and abnormal haemoglobin in red blood cells. The rate of exertional collapse is increased in athletes and military recruits who carry the trait, particularly in stressful environmental conditions. The aim of the present study was to investigate microvascular function and its determinants in response to intense exercise at control and warm environmental temperatures in carriers (AS) and non-carriers (AA) of sicklecelltrait. Nine AS and 11 AA, all healthy physically active young men, randomly participated in four experimental sessions (rest at 21 °C and 31 °C and cycling at 21 °C and 31 °C). All participants
SickleCellTrait and Risk for Common Diseases: Evidence from the UK Biobank. Sicklecelltrait is typically considered benign. Although evidence remains inconsistent, recent studies suggest that it is associated with several common diseases. We systematically assessed associations of sicklecelltrait with reported diseases in a large population-based cohort. Study subjects were self-reported Blacks from the UK Biobank (UKB), a United Kingdom population-based cohort of subjects aged 40-69 years at recruitment in the United Kingdom. Sickle cell status was based on the International Classification of Diseases, Tenth Revision (ICD-10) or mutations in the HBB gene. Diagnoses of diseases were obtained from ICD-10 and self-reports. Associations of sicklecelltrait and diseases were tested using
Tailored Parenting Plans of Young Adults With Sickle Cell Disease or SickleCellTrait. Our study purpose was to evaluate the variation and accuracy of tailored parenting plans individually generated as a supplement to reproductive health education on the genetic inheritance of sickle cell disease or sicklecelltrait. We present a secondary data analysis of experimental group data from
Association of Kidney Comorbidities and Acute Kidney Failure With Unfavorable Outcomes After COVID-19 in Individuals With the SickleCellTrait. Sicklecelltrait (SCT), defined as the presence of 1 hemoglobin beta sickle allele (rs334-T) and 1 normal beta allele, is prevalent in millions of people in the US, particularly in individuals of African and Hispanic ancestry. However, the association scale and phenotypes derived from International Classification of Diseases codes in the electronic health records. Of the 132 577 MVP participants with COVID-19 data, mean (SD) age at the index date was 64.8 (13.1) years. Sicklecelltrait was present in 7.8% of individuals of African ancestry and associated with a history of chronic kidney disease, diabetic kidney disease, hypertensive kidney disease
Parents' Experiences and Needs Regarding Infant SickleCellTrait Results. Sicklecelltrait (SCT) has reproductive implications and can rarely cause health problems. SCT counseling improves parent knowledge but is infrequently received by children with SCT compared with children with cystic fibrosis carrier status. There are no national guidelines on SCT disclosure timing, frequency
Sudden Death in High School Athletes: A Case Series Examining the Influence of SickleCellTrait. Athletes with sicklecelltrait (SCT) have up to a 37-fold increased risk of exercise-related death. Exertional collapse associated with sicklecelltrait (ECAST) is uncommon but can lead to exercise-related death due to exertional sickling. We present a case series of fatal ECAST in high school associated with sicklecelltrait is an uncommon but potentially deadly condition that is often underrecognized or misdiagnosed as exertional heat stroke. The development of ECAST is thought to be multifactorial with exercise intensity, recent illness, and exercising conditions (ie, heat and altitude). Prevention should be the primary goal for athletes with SCT through exercise modification, education
Effect of SickleCellTrait on Total Hip Arthroplasty in a Matched Cohort. It is unclear if sicklecelltrait (SCT) carrier status conveys an increased risk for poor outcomes following total hip arthroplasty (THA). The purpose of this study is to compare short-term clinical outcomes of THA for patients with SCT vs matched controls. Patient records were queried from the PearlDiver database using
The nephropathy of sicklecelltrait and sickle cell disease. Sickle cell syndromes, including sickle cell disease (SCD) and sicklecelltrait, are associated with multiple kidney abnormalities. Young patients with SCD have elevated effective renal plasma flow and glomerular filtration rates, which decrease to normal ranges in young adulthood and subnormal levels with advancing age . The pathophysiology of SCD-related nephropathy is multifactorial - oxidative stress, hyperfiltration and glomerular hypertension are all contributing factors. Albuminuria, which is an early clinical manifestation of glomerular damage, is common in individuals with SCD. Kidney function declines more rapidly in individuals with SCD than in those with sicklecelltrait or in healthy individuals. Multiple genetic
Association of SickleCellTrait With Incidence of Coronary Heart Disease Among African American Individuals. The incidence of and mortality from coronary heart disease (CHD) are substantially higher among African American individuals compared with non-Hispanic White individuals, even after adjusting for traditional factors associated with CHD. The unexplained excess risk might be due to genetic factors related to African ancestry that are associated with a higher risk of CHD, such as the heterozygous state for the sickle cell variant or sicklecelltrait (SCT). To evaluate whether there is an association between SCT and the incidence of myocardial infarction (MI) or composite CHD outcomes in African American individuals. This cohort study included 5 large, prospective, population-based cohorts
Evaluation of Stillbirth Among Pregnant People With SickleCellTrait. Relative to what is known about pregnancy complications and sickle cell disease (SCD), little is known about the risk of pregnancy complications among those with sicklecelltrait (SCT). There is a lack of clinical research among sickle cell carriers largely due to low sample sizes and disparities in research funding
