Studies have shown that platelets play an important role in the pathophysiology of vaso-occlusive crises (VOC) in sickle cell disease. This study investigates whether changes in platelet indices from baseline can be predictive of complications during acute pain crisis. Methods. Data were obtained from pediatric sickle cell patients in the well-clinic setting and compared with data gathered during VOC (n = 67). Primary outcome was complicated (admission, acute chest syndrome, transfusion, etc) versus uncomplicated (discharge from emergency department without subsequent return) course. Results. Patients with uncomplicated courses had larger platelet declines (53.7) than those with complicated courses (14.8, P = .005). Conclusions. The study suggests that patients with uncomplicated VOC are more likely to experience a larger decline in platelets. The predictive value is limited by the need to have preexisting steady-state data and relatively small decline. Ongoing studies are needed to identify useful laboratory data to help predict severity of VOC.<\/jats:p>","DOI":"10.1177\/0009922811399347","type":"journal-article","created":{"date-parts":[[2011,3,8]],"date-time":"2011-03-08T01:05:29Z","timestamp":1299546329000},"page":"657-661","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Changes in Platelet Count as a Predictive Tool in Sickle Cell Acute Vaso-Occlusive Crises: A Pediatric Study"],"prefix":"10.1177","volume":"50","author":[{"given":"Leticia A.","family":"Shanley","sequence":"first","affiliation":[{"name":"University of Texas-Southwestern, Dallas, TX, USA,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Myla","family":"Ebeling","sequence":"additional","affiliation":[{"name":"Medical University of South Carolina, Charleston, SC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
