Oxidative stress contributes to the complex pathophysiology of sickle cell disease. Oral therapy with pharmaceutical-grade l-glutamine (USAN, glutamine) has been shown increase proportion reduced form nicotinamide adenine dinucleotides in erythrocytes, which probably reduces oxidative and could result fewer episodes cell–related pain.

Sickle cell nephropathy begins in childhood and may progress to renal failure. Albuminuria is a sensitive marker of glomerular damage that indicate early chronic kidney disease (CKD).The aims this study were determine the cross-sectional prevalence clinical correlates albuminuria CKD among children with sickle (SCD). Over 10-year period (1995 2005) 410 pediatric SCD patients ages 2 21 years enrolled: 261 hemoglobin SS (HbSS) or HbSβ(0) thalassemia (HbSβ(0)) 149 HbSC HbSβ(+) (HbSβ(+)). The...

Background Health systems and providers across America are increasingly employing telehealth technologies to better serve medically underserved low-income, minority, rural populations at the highest risk for health disparities. The Patient-Centered Outcomes Research Institute (PCORI) has invested US $386 million in comparative effectiveness research telehealth, yet little is known about key early lessons garnered from this regarding best practices using address Objective This paper describes...

Transition of young adults with sickle cell disease (SCD) from pediatric to adult medical care is an important priority, given advances that have transformed SCD into a lifelong chronic condition, rather than childhood. Successful transfer has its foundation in collaboration among the adult, family, and health system support building skills positive management independent living. Systemic issues transition for individuals include limited access providers and/or interest caring people SCD;...

We report results of a pilot study high-dose vitamin D in sickle cell disease (SCD). Subjects were given 6-week course oral cholecalciferol (4000-100 000 IU per week) or placebo and monitored prospectively for period six months. Vitamin insufficiency deficiency was present at baseline 82·5% 52·5% subjects, respectively. who received achieved higher serum 25-hydroxyvitamin D, experienced fewer pain days week, had physical activity quality-of-life scores. These findings suggest potential...

The hallmark of sickle cell disease (SCD) is pain from a vaso-occlusive crisis. Although ambulatory accounts for most days in pain, also the common cause hospitalization and typically treated with parenteral opioids. evidence base lacking analgesic practice SCD, particularly optimal opioid dosing patient-controlled analgesia (PCA), part because challenges trial design conduct this rare disease.The purpose report to describe our Network's experiences protocol development, implementation,...

Abstract Background Invasive mold infections (IMI) are a leading cause of infectious mortality in allogeneic stem cell transplant (AlloSCT) recipients. Fluconazole, the current standard for fungal prophylaxis, is ineffective against molds. We initiated pilot study to determine safety and activity prophylactic liposomal amphotericin B (AMB) preventing IMI pediatric adolescent AlloSCT recipients during first 100 days. Procedure Fifty‐one patients (57 AlloSCT) were given AMB (3 mg/kg/day)...

Summary ‘Paradoxical’ embolization via intracardiac or intrapulmonary right‐to‐left shunts ( RLS ) is an established cause of stroke. Hypercoagulable states and increased right heart pressure, which both occur in sickle cell anaemia SCA ), predispose to paradoxical embolization. We hypothesized that children with overt stroke + stroke) have prevalence potential . performed contrasted transthoracic echocardiograms on 147 (aged 2–19 years) mean age 12·7 ± 4·8 years, 54·4% male) a control group...

The opioid medications codeine and hydrocodone, commonly prescribed in sickle cell disease (SCD), require metabolic conversion by cytochrome P450 2D6 (CYP2D6) to morphine hydromorphone, respectively, exert their analgesic effects. CYP2D6 gene is highly polymorphic, with variant alleles that result decreased, absent, or ultrarapid enzyme activity. Seventy-five children SCD were tested for polymorphisms, phenotypes inferred from the genotypes. most common CYP2D6*2 (normal activity, 28.7%),...

The prevalence of cerebrovascular events in sickle cell disease (SCD) can be as low 10% by the age 18 for overt cerebral infarction or strokes, up to 35% silent infarction, and high 43/100 patient years acute ischemic events. These typically occur during childhood with a peak incidence between 4 7 years. cumulative risk central nervous system SCD increases age. Transcranial Doppler (TCD) ultrasonography is an established screening tool detecting children at highest stroke measuring flow...

Abstract Background Abnormalities in bone mineral density (BMD) occur children treated for acute lymphoblastic leukemia (ALL). However, BMD estimates have been performed using varied instruments, reference data, and interpretations. This exploratory cross sectional study to evaluate mass with ALL, uses an algorithm that serially adjusts variables known affect pediatric measures by dual energy X‐ray absorptiometry (DXA), based on models developed 1,218 healthy adolescents. Procedure...
