100 young subjects with sickle cell disease were screened for hearing loss at the Sickle Cell Clinic at Arkansas Children's Hospital. 12% of the sample failed, which is higher than prevalence rates for the age groups suggest. Routine screening of hearing is suggested as the first step in the audiologic rehabilitation process.

The Relationship

The relationship between antiphospholipid antibodies (aPL) and sickle cell disease (SCD) has never been systematically addressed. Our aim was to evaluate potential links between SCD and aPL in all age groups. EMBASE/PubMed was screened from inception to May 2020 and Peto odds ratios for rare events were calculated. The pooled prevalence (PP) of IgG anticardiolipin antibodies (aCL) was higher in individuals with SCD than in controls (27.9% vs 8.7%, P < 0.0001), that of IgM aCL was similar in the two groups (2.9% vs 2.7%); only individuals with SCD were positive for lupus anticoagulant (LA) (7.7% vs 0%, P < 0.0001). The PP of leg ulcers was similar between aPL positive and negative individuals (44% vs 53%) and between patients in acute crisis and stable patients (5.6% vs 7.3%). Reporting of aPL as a binary outcome and not as a titer precluded further interpretation. The results indicate that a prospective case-control study with serial measurements of a panel of aPL in SCD patients might be warranted, in order to understand further the possible pathogenic role of aPL in SCD.

Hematological and biochemical reference values in sickle cell disease (SCD) are crucial for patient management and the evaluation of interventions. This study was conducted at Muhimbili National Hospital (MNH) in Dar es Salaam, Tanzania, to establish laboratory reference ranges among children and adults with SCD at steady state. Patients were grouped into five age groups and according to their sex. Aggregate functions were used to handle repeated measurements within the individual level in each age group. A nonparametric approach was used to smooth the curves, and a parametric approach was used to determine SCD normal ranges. Comparison between males and females and against the general population was documented. Data from 4422 patients collected from 2004–2015 were analyzed. The majority of the patients (35.41%) were children aged between 5–11 years. There were no significant differences (p ≥ 0.05) in mean corpuscular hemoglobin concentration (MCHC), lymphocytes, basophils, and direct bilirubin observed between males and females. Significant differences (p < 0.05) were observed in all selected parameters across age groups except with neutrophils and MCHC in adults, as well as platelets and alkaline phosphatase in infants when the SCD estimates were compared to the general population. The laboratory reference ranges in SCD at steady state were different from those of the general population and varied with sex and age. The established reference ranges for SCD at steady state will be helpful in the management and monitoring of the progress of SCD.

Chi Square Analysis

Introduction: Sickle cell disease (SCD) is associated with recurrent complications and healthcare burden. Although SCD management guidelines differ based on age groups, little is known regarding actual utilization of preventative (hydroxyurea) and palliative therapies (opioid and nonopioid analgesics) to manage complications. This study assessed whether there were age-related differences in SCD index therapy type and SCD-related medication utilization.Design and patients: Texas Medicaid prescription claims from September 1, 2011 to August 31, 2016 were retrospectively analyzed for SCD patients aged 2-63 years who received one or more SCD-related medications (hydroxyurea, opioid, or nonopioid analgesics).Outcome measures: The primary outcomes were SCD index drug type and medication utilization: hydroxyurea adherence, and days’ supply of opioid, and nonopioid analgesics. Chi-square, analysis of variance, and Kruskal–Wallis tests were used.Results: Index therapy percentages for included patients (N = 2,339) were the following: opioids (45.7 percent), nonopioids (36.6 percent), dual therapy-opioids and nonopioids (11.2 percent), and hydroxyurea (6.5 percent), and they differed by age-groups (χ2 = 243.0, p 0.0001). Hydroxyurea as index therapy was higher among children (2-12:9.1 percent) compared to adults (26-40:3.7 percent; 41-63:2.9 percent). Opioids as index therapy were higher among adults (18-25:48.0 percent; 26-40:54.9 percent; 41-63:65.2 percent) compared to children (2-12:36.6 percent). Mean hydroxyurea adherence was higher (p 0.0001) for younger ages, and opioid days’ supply was higher for older ages.Conclusions: Texas Medicaid SCD patients had low hydroxyurea utilization and adherence across all age groups. Interventions to increase the use of hydroxyurea and newer preventative therapies could result in better management of SCDrelated complications and reduce the frequency of pain crises, which may reduce the need for opioid use.

Age Range

Abstract Neuraminic (sialic) acid concentrations in serum from normal and sickle cell (HbSS) subjects were determined for discrete age groups from childhood through adolescence. Values in sickle cell disease were consistently lower over the entire age range. We further investigated the effect of exogenous sialic acid on the rate of sickling reversion of HbSS erythrocytes and demonstrated that this compound in millimole per liter concentrations could revert pre-sickled erythrocytes to their normal morphology in a concentration-dependent manner. When subjected to partial de-sialation with sialidase (EC 3.2.1.18), the HbSS erythrocytes not only sickled faster upon deoxygenation, they also reverted more slowly on treatment with phenylalanine (a more efficient anti-sickling agent than sialic acid) than did untreated cells. We conclude that, in sickle cell disease, erythrocyte sialic acid content could play a significant role, not only in the control of the sickling rate in vivo, but also, after sickling has occurred, in the rate of recovery from a sickling crisis.

Abstract In recent years, several sickle cell–specific quality indicators have been developed using rigorous approaches. A review of the history and current status of the development of sickle cell–specific indicators highlights opportunities for future refinement. Despite efforts at alignment, lack of strong evidence hinders the adoption of current quality indicators across stakeholder groups. There are many directions in which to take the current existing quality indicators, including expanding to different age groups, aims of care such as safety and equity, and better understanding of contextual and environmental factors.
