Cerebro-spinal fluid eosinophilia in shunt infections

Hypereosinophilia has been detected in the CSF of 22 patients in a series of 81 cases of shunt infection. It was related with the evolution of the sepsis. Its persistence at the end of treatment appeared to predict later complications, septic or obstructive, and it could be the sign of latent infection. HE might be the result of a specific reaction directed against the infected material, but a non-specific process cannot be eliminated.
