Glucocorticosteroid treatment for cerebrospinal fluid eosinophilia in a patient with ventriculoperitonial shunt.

BACKGROUND

Cerebrospinal fluid (CSF) eosinophilia commonly occurs in patients with ventriculoperitoneal (VP) shunts and is associated with shunt complications such as obstruction or infection. Glucocorticosteroids (GCS) are effective in reducing eosinophilia and eosinophils in skin, nasal mucosa, and airway epithelium. Effects of GCS on CSF eosinophils has not been reported.

OBJECTIVE

To demonstrate glucocorticosteroid effects on the CSF eosinophil levels and to propose that GCS may be used as a therapeutic agent for CSF eosinophilia.

RESULT

A case report of a patient with congenital hydrocephalus and a VP shunt developed CSF eosinophilia associated with latex allergy and shunt malfunction. Daily treatment with 2 mg/kg of methylprednisolone was associated with reduced peripheral eosinophilia and slightly reduced CSF eosinophil counts. Pulse methylprednisolone, 15 mg/kg, was associated with complete reduction of CSF eosinophils and prolonged VP shunt survival.

CONCLUSION

Systemic glucocorticosteroids effectively reduce CSF eosinophils. Glucocorticosteroids may be beneficial for treatment of CSF eosinophilia associated with VP shunt malfunction.
