Plasma exchange for acute cholestasis in homozygous sickle cell disease

Area of Science:

• Pediatrics
• Hematology
• Nephrology

Background:

• Sickle cell disease (SCD) is a genetic blood disorder with diverse clinical manifestations.
• Acute chest syndrome, cholestasis, and neurological complications are severe SCD manifestations.
• The underlying mechanisms of these multi-organ complications in SCD require further elucidation.

Purpose of the Study:

• To report a case of a child with sickle cell disease presenting with a rare combination of severe complications.
• To investigate the potential role of immune complexes in the pathogenesis of these complications.
• To evaluate the efficacy of plasma exchange in managing this complex clinical scenario.

Main Methods:

• Clinical case presentation of a pediatric patient with sickle cell disease.
• Laboratory investigations including bilirubin, LDH, alkaline phosphatase, urea, and creatinine levels.
• Measurement of circulating immune complexes.
• Therapeutic intervention with plasma exchange.

Main Results:

• The patient presented with acute chest syndrome, acute cholestasis, and neurological syndrome.
• Markedly elevated levels of bilirubin, LDH, alkaline phosphatase, urea, and creatinine were observed.
• Slightly elevated circulating immune complexes were detected.
• Dramatic clinical improvement was achieved following plasma exchange.

Conclusions:

• Plasma exchange can be a highly effective treatment for severe, multi-systemic complications in children with sickle cell disease.
• The findings suggest a potential role for immune dysregulation in the severe manifestations of SCD.
• This case underscores the importance of prompt and aggressive management for life-threatening SCD complications.
