Isolated abducens nerve palsy treated by immunoadsorption in a patient with diarrhea-associated hemolytic uremic syndrome
Abstract
Shiga toxin-producing Escherichia coli (STEC) that causes a prodromal hemorrhagic enteritis is the main cause of hemolytic uremic syndrome (HUS) particularly in pediatric patients. It is characterized by acute kidney injury with microangiopathic hemolytic anemia and thrombocytopenia. The kidney and brain are the two major target organs, and neurological involvement is the most frequent cause of mortality. The time delay between bloody diarrhea and neurological symptoms ranges from few days to a month. Neurological disorders include disturbances in cognitive functions, focal neurological signs, epileptic seizures, myoclonus and neuropsychiatric symptoms. Cerebral magnetic resonance imaging reveals various patterns of hyperintensities distributed through cerebral matter or may be totally normal even the patient has severe neurological involvement. Electroencephalography usually show generalized or focal slowing of the background activity, spikes or sharp waves despite being normal in around 20% of patients. We present here an adult male patient referred to our center with requirement of hemodialysis due to diarrhea-associated HUS complicated by acute kidney injury. Later during the course of plasma exchange therapy the patient developed an isolated abducens nerve palsy. Complete renal recovery was achieved by plasma exchange therapy but abducens palsy remedied rescue introduction of immunoglobulin G (IgG) depletion by immunoadsorption.
