Encephalitis is defined as inflammation of the brain parenchyma associated with neurological dysfunction . Limbic encephalitis (LE) is characterized by rapid development of confusional episodes, memory deficits, mood changes, and epileptic seizures.
While paraneoplastic LE generally has a poor prognosis, autoimmune LE often responds well to immunotherapy . In case series, but not controlled studies, patients with autoimmune encephalitis have been shown to benefit from first-line immunotherapies that include corticosteroids, intravenous immunoglobulins (IVIG) therapy, and plasma exchange, either alone or in combination .
In this paper, we report on the efficacy of 20%-concentrated subcutaneous immunoglobulin G (SCIG, Hizentra®, CSL Behring AG) in a patient with autoimmune encephalitis, treated initially and successfully with IVIG. To our knowledge, this is the first clinical case with SCIG showing a maintenance of the outcomes with IVIG. In December 2016, a...
