<p class="Pa7">Sickle cell anemia (SCA) is a common hematological disorder among individu­als of African descent in the United States; the disorder results in the production of abnormal hemoglobin. It is caused by homozygosity for a genetic mutation in HBB; rs334. While the presence of a single mutation (sickle cell trait, SCT) has long been considered a benign trait, recent research suggests that SCT is associated with renal dysfunction, including a decrease in estimated glomerular filtration rate (eGFR) and increased risk of chronic kidney disease (CKD) in African Americans. It is currently unknown whether similar associations are observed in Hispanics. Therefore, our study aimed to determine if SCT is associated with mean eGFR and CKD in a sample of 340 Dominican Hispanics from the Northern Manhattan Study. Using regression analyses, we tested rs334 for association with eGFR and CKD, adjusting for age and sex. eGFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration equa­tion and CKD was defined as eGFR &lt; 60 mL/min/1.73 m2. Within our sample, there were 16 individuals with SCT (SCT carriers). We found that SCT carriers had a mean eGFR that was 12.12 mL/min/1.73m2 lower than non-carriers (P=.002). Additionally, SCT carriers had 2.72 times higher odds of CKD compared with non-carriers (P=.09). Taken together, these novel results show that Hispanics with SCT, as found among African Americans with SCT, may also be at increased risk for kidney disease.</p><p class="Pa7"><em>Ethn Dis. </em>2017; 27(1)<strong>:</strong>11-14; doi:10.18865/ed.27.1.11.</p><p class="Pa7"> </p>

Introduction: Sickle cell trait (SCT) is an independent risk factor for chronic kidney disease (CKD). CKD is a well-established risk factor for progressive cardiovascular dysfunction. Sickle Cell trait has been noted to promote a persistent systemic pro-inflammatory state. This pro-inflammatory state could potentially increase the risk of systemic endothelial dysfunction when accompanied with other cardiotoxic conditions. We aim to investigate cardiovascular outcomes in patients with SCT and CKD, compared to SCT alone. Methods: Patients with CKD were identified in the National Inpatient Sample (NIS) database 2016 using the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM), and subsequently were divided into two groups, those with and without SCT. Both population sets were paired using 1:1 propensity score matching based on Age, Sex and co-morbidities to address potential confounding factors. Outcomes of interest were overall mortality, rates of stroke, sudden cardiac arrest (SCA) and cardiomyopathy. Results: Mean age of patients with CKD alone was 72.98 ± 13.2 years, while for CKD and SCT 56.68 ± 17.3 years. There was no significant difference between the two group in the rates of stroke (1.3% vs 1.0%; P= 0.125), and SCA (1.0% vs 1.1%; P= 0.841). Overall mortality (5.7% vs 2.2%; P<0.0001) and rates of cardiomyopathy (10.1% vs 2.9%; P<0.0001) were significantly lower in patients with CKD and SCT, compared to CKD alone. Multivariate logistic regression followed a similar trend, compared to those with CKD alone, the adjusted odds ratio (aOR) for overall mortality aOR; 0.625 (0.372-1.049) and cardiomyopathy aOR; 0.451 (0.293-0.696) were significantly lower in patients with CKD and SCT. Conclusion: Compared to patients with CKD alone, those with CKD and SCT have a lower risk for overall mortality and cardiomyopathy. Further studies are needed to replicate this finding and look at the possible protective role of SCT in patients with CKD.

The Mean

Background: Sickle cell trait (SCT) is common among African Americans and has been historically considered to be benign. Recently, SCT has been associated with an increased risk for chronic kidney disease (CKD) and cardiovascular disease in the general population. Our understanding of SCT has been extrapolated largely from data of patients with sickle cell disease (SCD). Notably, in SCD, the outcomes differ by sex. The effect of SCT on cardiovascular risk in the African American CKD population is unknown, and the interaction between SCT and sex on cardiovascular risk has not been investigated. Methods: We performed a 2-center retrospective cohort study of all African American patients with SCT using international classification of disease diagnosis codes and CKD (using the 2012 Kidney Disease Improving Global Outcomes criteria) with at least 1 year of follow-up between January 2005 and December 2017. A reference group of ­African American CKD patients without SCT was used as a comparator during the same period. SCT patients and the reference patients were matched at baseline for age, sex, comorbidities, and proteinuria. Primary outcomes were incident coronary artery disease (CAD), incident stroke, and all-cause mortality. Analysis of effect modification between sex and SCT on primary outcomes was performed. Results: We identified 621 African American CKD patients, 217 SCT patients, and 404 reference patients. The mean age was 56 ± 13 years and 66% were female. The mean estimated glomerular filtration rate was 69 ± 30 mL/min. The mean follow-up time was 8 ± 4 years. There were no significant differences in the primary outcomes comparing SCT patients to matched controls. The interaction term between SCT and sex, however, was significant in the CAD model (p < 0.01). Stratification by sex showed no increased risk in females but a significantly increased risk for CAD in male SCT patients (hazard ratio [HR] 2.14; 95% CI 1.18–3.86), which persisted after multivariable analysis (HR 2.13; 95% CI 1.17–3.86). Conclusion: SCT is associated with an increased risk for CAD in African American males with CKD. The excess risk in males with SCT appears to follow the same pattern as risk in males with SCD. Larger studies are needed to confirm these findings.
