    Abstract:
    BACKGROUND: To investigate for pretreatment clinical variables to predict the outcome of new-onset epileptic spasms after adrenocorticotropic hormone (ACTH) therapy and to identify risk factors for poor long-term outcome. METHODS: We retrospectively studied 129 consecutive patients with infantile spasms syndrome (ISS). These patients received ACTH with antiseizure medication therapy for the first time and were regularly followed up for more than six months at our hospital. The response to treatment was assessed after two weeks of ACTH injection. Kaplan-Meier survival analysis and the multivariate Cox proportional hazard regression model were used. RESULTS: Among the 129 patients, 61 (47.3%) had a good response after two weeks of ACTH treatment. At the time of the latest follow-up, 71 (55%) patients were seizure-free (International League Against Epilepsy class1). The univariate analysis revealed that normal neurodevelopment (P = 0.018), time lag of less than one month (P = 0.026), no hypsarrhythmia on EEG (P = 0.004), and serum calcium level ≥2.50 mmol/L (P = 0.035) were significantly associated with a good response. Only a good response to ACTH therapy was significantly associated with a positive long-term outcome. The Kaplan-Meier survival analysis showed that serum calcium level ≧2.50 mmol/L was significantly associated with a positive long-term outcome (P = 0.030). Multivariate analysis confirmed that no response to ACTH therapy was an independent variable that predicted long-term seizure recurrence (P < 0.001, hazard ratio = 4.602, confidence interval = 2.252 to 9.406). CONCLUSIONS: A good response to ACTH therapy had a significant predictive value for long-term seizure outcomes. Calcium may play an important role in the treatment of ISS with ACTH.
