This is the first study of Intravenous immunoglobulins (IVIG) therapy on a large number of patients with West syndrome.
IVIG therapy is rarely effective as the initial treatment in West syndrome.
The efficacy of IVIG therapy in our study was lower than that in previous studies.
IVIG therapy has a good safety profile and we would recommend it for West syndrome cases with drug resistance, severe complications associated with profound brain damage, severe brain atrophy, and in immunocompromised patients.
Patients with short treatment lag showed better seizure outcomes in IVIG therapy.
