Hemolytic uremic syndrome (HUS) in associated with infections of neuraminidase-producing streptococcus pneumoniae was rarely reported in the literature. We report two infants with proven pneumococcal meningitis associated with anemia, thrombocytopenia, renal failure, and T-antigen activation characteristic of neuraminidase activity. This supports a common pathogenesis in HUS following infection of neuraminidase-producing strains of S. pneumoniae. One infant complicated with status epilepticus died, and the other infant survived without sequelae. We recommend that neuraminidase production should be considered in case of pneumococcal meningitis associated with anemia and thrombocytopenia without diffuse bleeding tendency. Early recognition of HUS associated S. pneumoniae neuraminidase production is vital. The use of compatible washed red blood cells, meticulous supportive care and appropriate use of dialysis will improve survival.

Interictal spikes have been implicated in epileptogenesis and cognitive dysfunction in epilepsy. Unfortunately, antiepileptic drugs have shown poor efficacy in suppressing interictal discharges; novel therapies are needed. Surface charge on neuronal membranes provides a novel target for abolishing interictal spikes. This property can be modulated through the use of neuraminidase, an enzyme that decreases the amount of negatively charged sialic acid. In the present report we determined whether applying neuraminidase to brains of rats with a history of status epilepticus would reduce number of interictal discharges. Following pilocarpine-induced status epilepticus, rats received intrahippocampal injections of neuraminidase, which significantly decreased the number of interictal spikes recorded in the CA1 region. This study provides evidence that sialic acid degradation can reduce the number of interictal spikes. Furthermore, the results suggest that modifying surface charge created by negatively charged sialic acid may provide new opportunities for reducing aberrant epileptiform events in epilepsy.
