The Role of Corticosteroids in Non-Bacterial and Secondary Encephalitis

Encephalitis affects 1.9 to 14.3 people per 100,000 each year, and the mortality rate varies but can be up to 40%. After the identification of a particular microorganism in a patient with encephalitis, appropriate antimicrobial therapy should be initiated. Corticosteroid therapy represents a therapeutic option in the treatment of primary central nervous system diseases due to its ability to reduce the inflammatory commitment of CNS and consequently reduce mortality rates regardless of the causative agent of injury. Corticosteroid therapy represents a therapeutic option in the treatment of primary central nervous system diseases. Their use is also recommended in meningitis with autoimmune etiology. While corticosteroids have repeatedly been used as adjunctive treatment in encephalitis of viral etiology, the scientific evidence supporting their effectiveness remains scarce. The use of standard doses recommended by the guidelines seems reasonable as an initial setting, especially when a definitive diagnosis of the causal agent is still awaited. The subsequent adjustment should be personalized based on the individual clinical response.
