Abstract
SUMMARY: Tapered oral dexamethasone for acute chest syndrome (ACS) in sickle cell anaemia was studied using a novel ACS assessment tool and investigational biomarkers. Twelve participants were randomized (mean age 17·3 years) before early study termination. Dexamethasone decreased duration of hospitalization for ACS by 20·8 h compared to placebo (P = 0·024). Rebound pain occurred in both groups (3 dexamethasone versus 1 placebo). Overall, dexamethasone decreased the leucocyte activation biomarker, sL-selectin; however, participants with rebound pain had higher sL-selectin within 24 h of treatment (dexamethasone or placebo). This ACS assessment tool was feasibly applied, and sL-selectin is a promising biomarker of ACS therapy.
