Neurologic complications with elevated antibody titer after acute hemorrhagic conjunctivitis.

Nine patients with polyradiculomyeloneuropathy after acute hemorrhagic conjunctivitis (AHC) infection were studied serologically. All except one patient had neutralization titers larger than or equal to 1:16 against the prototype J670/71 strain of AHC virus in at least one of their serum samples. The development of a significant fourfold rise in antibody titer against AHC virus occurred in one of the patients who developed neurologic complications five days after the onset of AHC infection.
