Factors associated with survival in a contemporary adult sickle cell disease cohort: Factors Associated with Survival in Sickle Cell Disease

We examined the relationship of clinical differences among sickle cell disease (SCD) patients in order to understand the major contributors to early mortality in a contemporary cohort

Immune Reconstitution after Haploidentical Donor and Umbilical Cord Blood Allogeneic Hematopoietic Cell Transplantation

Allogeneic hematopoietic cell transplantation (HCT) is the only potentially curative therapy for a variety of hematologic diseases. However, this therapeutic platform is limited by an initial period when patients are profoundly immunocompromised. There is gradual immune recovery over time, that varies by transplant platform. Here, we review immune reconstitution after allogeneic HCT with a specific focus on two alternative donor platforms that have dramatically improved access to allogeneic HCT for patients who lack an HLA-matched related or unrelated donor: haploidentical and umbilical cord blood HCT. Despite challenges, interventions are available to mitigate the risks during the immunocompromised period including antimicrobial prophylaxis, modified immune suppression strategies, graft manipulation, and emerging adoptive cell therapies. Such interventions can improve the potential for long-term overall survival after allogeneic HCT

Trends and in-hospital cardiac complications in patients with atrial fibrillation undergoing allogeneic stem cell transplant: A National Inpatient Sample analysis (2002-2019)

BACKGROUND: Cardiovascular comorbidities increase the risk of transplant-associated complications. However, the impact of atrial fibrillation (AF) as an independent risk factor remains limited. METHODS: The National Inpatient Sample (NIS) database was queried using the International Classification of Diseases codes to identify patients admitted for allogeneic stem cell transplant (ASCT). The patients were then subclassified into with and without AF. Subsequently, a multivariate logistic regression model was constructed to account for patient demographics, comorbidities, and hospital characteristics to evaluate the impact of AF on the primary outcome of interest: all-cause mortality, and secondary outcomes of interest that included common hospitalization complications. RESULTS: The data for 77 157 cases of ASCT were collected between 2002 and 2019. Among these 5086 (6.6%) cases had concurrent AF. Multivariate logistic regression revealed patients undergoing ASCT with AF had almost a three times higher risk of all-cause mortality (odds ratio = 2.99 [95% confidence interval: 2.73-3.28]; p \u3c .01). AF patients also had a higher risk for cardiac arrest, cardiogenic shock, acute kidney injury, and need for hemodialysis (all p \u3c .01). CONCLUSION: AF causes a higher risk of death and cardiovascular complications among patients undergoing ASCT. This signifies the importance of pretransplant consultation and optimization for cardiovascular comorbidities to improve hospitalization outcomes

Factors associated with survival in a contemporary adult sickle cell disease cohort

In this study, the relationship of clinical differences among patients with sickle cell disease (SCD) was examined to understand the major contributors to early mortality in a contemporary cohort. Survival data were obtained for 542 adult subjects who were enrolled since 2002 at three university hospitals in the southeast United States. Subjects were followed up for a median of 9.3 years. At enrollment, clinical parameters were collected, including hemoglobin (Hb) genotype, baseline laboratory values, comorbidities, and medication usage. Levels of soluble adhesion molecules were measured for a subset of 87 subjects. The relationship of clinical characteristics to survival was determined using regression analysis. Median age at enrollment was 32 years. Median survival was 61 years for all subjects. Median survival for Hb SS and Sb 0 was 58 years and for Hb SC and Sb 1 was 66 years. Elevated white blood count, lower estimated glomerular filtration rate, proteinuria, frequency of pain crises, pulmonary hypertension, cerebrovascular events, seizures, stroke, sVCAM-1, and short-acting narcotics use were significantly associated with decreased survival. Forty-two percent of subjects were on hydroxyurea therapy, which was not associated with survival. SCD continues to reduce life expectancy for affected individuals, particularly those with Hb Sb 0 and SS. Not only were comorbidities individually associated with decreased survival but also an additive effect was observed, thus, those with a greater number of negative endpoints had worse survival (P < 0.0001). The association of higher sVCAM-1 levels with decreased survival suggests that targeted therapies to reduce endothelial damage and inflammation may also be beneficial

Outcomes of CD19-Targeted Chimeric Antigen Receptor T Cell Therapy for Patients with Reduced Renal Function Including Dialysis.

Patients with renal impairment (RI) are typically excluded from trials evaluating chimeric antigen receptor (CAR) T cell therapies. We evaluated the outcomes of patients with RI receiving standard of care (SOC) CAR T cell therapy for relapsed/refractory (R/R) diffuse large B cell lymphoma (DLBCL). In this retrospective, single-center cohort study of patients with R/R DLBCL treated with SOC axicabtagene ciloleucel (axi-cel) or tisagenlecleucel (tisa-cel) after 2 or more prior lines of therapy, renal and survival outcomes were compared based on RI and fludarabine dose reduction (DR) status. RI was defined by an estimated glomerular filtration rate/min/1.73
