Longitudinal outcomes of chronically transfused adults with sickle cell disease and a history of childhood stroke.

Background: Many children with sickle cell disease (SCD) who suffer a stroke receive chronic transfusion therapy (CTT) indefinitely; however, their adulthood neurologic outcomes have not been reported. Understanding these outcomes is critical to inform decisions regarding curative therapy in childhood.

Study Design And Methods: In this retrospective study, we described a cohort of adults with SCD and a history of childhood stroke who received care at a single center and compared their outcomes with matched subjects without childhood stroke using chi and Mann-Whitney U tests.

Late effects of hemopoietic stem cell transplant for sickle cell disease: monitoring and management.

Introduction: Allogeneic hemopoietic stem cell transplantation (HSCT) is a curative therapy for sickle cell disease (SCD). Exposure to both SCD and HSCT conditioning regimens is associated with late health effects.

Areas Covered: This review addresses post-HSCT outcomes and late health effects among individuals with SCD exposed to allogeneic HSCT regimens, summarizes recommendations for long-term care, and identifies future survivorship research needs.

Prophylactic red cell transfusions for sickle cell disease pregnancy: increased use of therapy could transform outcomes.

Purpose Of Review: Pregnancy for people with sickle cell disease (SCD) is high risk with persistently high rates of severe maternal and fetal mortality and morbidity. Transfusion therapy is the best-studied treatment for SCD in pregnancy; hydroxyurea is not usually used because of teratogenicity concerns. In high-resource settings, red cell transfusions are likely underutilized, while in low-resource settings, they may be altogether unavailable.

Sickle cell disease and infertility risks: implications for counseling and care of affected girls and women.

Introduction: Sickle cell disease (SCD), its treatments and cures present infertility risks. Fertility counseling is broadly indicated for affected girls and women and fertility preservation may appeal to some. Several streams of evidence suggest that the reproductive lifespan of women with SCD is reduced.

Managing sickle cell disease and related complications in pregnancy: results of an international Delphi panel.

Data to guide evidence-based management of pregnant people with sickle cell disease (SCD) are limited. This international Delphi panel aimed to identify consensus among multidisciplinary experts for SCD management during pregnancy. The 2-round Delphi process used questionnaires exploring 7 topics (antenatal care, hydroxyurea use, transfusion, prevention of complications, treatment of complications, delivery and follow-up, and bottlenecks and knowledge gaps) developed by a steering committee.

Psychiatry referral and appointment attendance in a clinic for young adults with sickle cell disease.

Mental illness is a common sickle cell disease (SCD) comorbidity. This observational study evaluated psychiatry appointment attendance among 137 young adults with SCD. In their first year of adult SCD care, 43% of subjects were referred to psychiatry.

Blood pressure thresholds for the diagnosis of hypertensive disorders of pregnancy in sickle cell disease.

In this retrospective cohort study of singleton pregnancies in people with sickle cell disease (SCD) delivered at two academic centres between 1990 and 2021, we collected demographic and SCD-related data, pregnancy outcomes, and the highest systolic and diastolic blood pressure (SBP and DBP) at seven time periods. We compared the characteristics of subjects with new or worsening proteinuria (NWP) during pregnancy to those without. We then constructed receiver operating characteristic (ROC) curves to determine the blood pressure (BP) that best identifies those with NWP.

How young adults with sickle cell disease define "being a good patient" in the adult healthcare system.

Background: Young adulthood brings new challenges for managing sickle cell disease. There are fewer adult specialists, sickle cell disease morbidities accumulate, and mortality increases. Developmental changes in roles and responsibilities also affect management.

Natural history of blood pressure in sickle cell disease pregnancy.

In this retrospective cohort study of singleton pregnancies in people with sickle cell disease (SCD) delivered at two academic centres between 1990 and 2021, we collected demographic and SCD-related data, pregnancy outcomes, and the highest systolic and diastolic blood pressure (SBP and DBP) at seven time periods. We compared blood pressure values and trajectories in the composite cohort and in each genotype group to control values in a non-SCD pregnancy dataset. There were 290 pregnancies among 197 patients with SCD.

"Buprenorphine, It Works so Differently": Adults with Sickle Cell Disease Describe Transitioning to Buprenorphine for Treatment of Chronic Pain.

A growing body of literature describes the use of buprenorphine for the treatment of chronic pain in people with sickle cell disease. The experiences of people with sickle cell disease who have tried buprenorphine have not yet reported. This qualitative descriptive study was conducted to explore perspectives on buprenorphine for chronic pain in sickle cell disease.

"The Patient Should Have a Choice": Adults with Sickle Cell Disease Advise Integration of Telemedicine into the Comprehensive Sickle Cell Disease Care Model.

Background: Adults with sickle cell disease (SCD) constitute a unique and vulnerable patient population with complex healthcare needs including routine follow-up visits and acute care evaluations. The COVID-19 pandemic accelerated healthcare systems' transition to providing telemedicine care. The purpose of this qualitative study was to elicit the perspectives of adults with SCD about their experience with telemedicine during the COVID-19 pandemic and to understand their preferences with respect to future telemedicine care.

Alpha globin gene copy number and incident ischemic stroke risk among Black Americans.

Introduction: People with African ancestry have greater stroke risk and greater heritability of stroke risk than people of other ancestries. Given the importance of nitric oxide (NO) in stroke, and recent evidence that alpha globin restricts nitric oxide release from vascular endothelial cells, we hypothesized that alpha globin gene ( deletion would be associated with reduced risk of incident ischemic stroke.

Methods: We evaluated 8,947 participants self-reporting African ancestry in the national, prospective Reasons for Geographic And Racial Differences in Stroke (REGARDS) cohort.

Knowledge of fertility and perception of fertility treatment among adults with sickle cell disease (KNOW FERTILITY).

Introduction: This study assessed fertility knowledge in adults with sickle cell disease using the Cardiff Fertility Knowledge Scale and Fertility Treatment Perception Survey and compared knowledge scores in respondents with sickle cell disease to previously reported unaffected cohorts.

Methods: This cross-sectional study surveyed adults over age 18 with sickle cell disease at an adult sickle cell disease center using a 35-question survey addressing infertility risk factor knowledge and perceptions of fertility treatment. Analyses included summary statistics for continuous and categorical variables, univariate linear regression, and Mann-Whitney U tests for group comparisons of Fertility Knowledge Scale scores.

High Dietary Sodium, Measured Using Spot Urine Samples, is Associated with Higher Blood Pressure among Young Adults in Haiti.

Background: Hypertension (HTN) is the leading cardiovascular disease (CVD) risk factor in Haiti and is likely driven by poverty-related social and dietary factors. Salt consumption in Haiti is hypothesized to be high but has never been rigorously quantified.

Methods: We used spot urine samples from a subset of participants in the population-based Haiti Cardiovascular Disease Cohort to estimate population mean daily sodium intake.

Comparisons of Severe Maternal Morbidity and Other Adverse Pregnancy Outcomes in Pregnant People With Sickle Cell Disease vs Anemia.

Importance: Pregnancy in sickle cell disease (SCD) is high risk, but whether prenatal anemia, which is treatable with red blood cell transfusions, is a mediator associated with adverse pregnancy outcomes (APOs) is not known.

Objective: To compare rates and odds of severe maternal morbidity (SMM) and other APOs in pregnancies among individuals with SCD vs those without SCD but with prenatal anemia.

Design, Setting, And Participants: This cross-sectional study was conducted using data from 2012 to 2018 from the National Inpatient Sample, a nationally representative sample of 20% of acute hospital admissions in the United States.

Severe Maternal Morbidity and Mortality in Sickle Cell Disease in the National Inpatient Sample, 2012-2018.

Importance: Pregnancy outcomes are historically poor among people with sickle cell disease (SCD) in the US, most of whom have Black race. Whether outcomes have improved is unknown.

Objective: To tabulate adverse pregnancy outcomes among patients with SCD, comparing outcomes of deliveries among Black people with SCD with those of Black people without SCD and a control non-Black population, and to measure the association of racial disparities with adverse outcomes in SCD pregnancies.
