英文摘要
Project Summary
Sickle cell disease (SCD), one of the most common inherited disorders, effects an estimated 100,000
Americans, mostly of African-American descent, as well as millions globally. Despite current
preventative/treatment modalities, SCD morbidity is associated with premature mortality and substantial
financial and quality of life costs. A hallmark of SCD is the vaso-occlusive pain crisis, a recurrent,
unpredictable, and debilitating event. Demographic factors, genotype, psychosocial factors, socioeconomic
status (SES) and environmental exposures have been linked with SCD pain crises. Although the precise
pathophysiology of vaso-occlusive crises is not fully understood, identified mechanisms are markedly similar to
those postulated for the well-established associations of cardiovascular morbidity and mortality with ambient air
pollution exposures. While it is biologically plausible that exposure to ambient air pollution could be associated
with increased risk of sickle cell pain crises, epidemiologic research is very limited. The proposed study takes
advantage of an existing statewide hospital administrative dataset; complex, innovative spatio-temporal
particulate matter (PM) and component exposure models developed for previously funded research;
hierarchical Bayesian ozone exposure models developed by the US EPA; and the case crossover study
design. We will examine whether hospitalizations and emergency department visits for vaso-occlusive pain
crises among SCD patients are associated with short-term exposures to ambient air pollutants. The proposed
study will, to the best of our knowledge, be the first to evaluate comprehensively the effects of ozone, PM2.5,
and biologically relevant traffic-related PM components on SCD vaso-occlusive pain crises among a statewide
population with a high rate of reported SCD-related mortality. The results of our study could advance
understanding of pathophysiological responses to air pollution among a population experiencing debilitating
and costly adverse outcomes.
