Key Findings
- Purpose
To describe clinical presentation, diagnostic challenges, and management of fat embolism syndrome (FES) in adolescents with sickle cell disease (SCD). - Population (Model)
Case series of three adolescents with SCD (HbSS and HbS-β+ thalassemia) presenting with severe vaso-occlusive episodes complicated by respiratory failure and neurologic impairment. - Headline Result
This small case series (n = 3) highlights that FES in SCD can present with acute respiratory failure, altered mental status, and characteristic neuroimaging findings (microhemorrhages and infarcts), with clinical improvement observed following red blood cell exchange (RBCX) and, in some cases, therapeutic plasma exchange (TPE). - Why It Matters
FES is a rare but life-threatening complication of SCD that is frequently underrecognized. These cases underscore the importance of early suspicion in patients with unexplained neurologic or respiratory deterioration, where timely intervention may influence outcomes. - Evidence Gaps & Limitations
Extremely small sample size and descriptive design limit generalizability. The role of TPE in addition to RBCX remains exploratory, with no controlled comparisons to establish efficacy or standardize treatment protocols.

Regulatory & Guideline Watch
The American Society of Hematology recommends red blood cell exchange in severe complications of sickle cell disease, including acute chest syndrome and neurologic events. Fat embolism syndrome is not explicitly addressed in current guidelines, reflecting limited evidence and reliance on case-based management approaches.
