ObjectiveAnalyze the clinical features of epilepsy induced by tuberous sclerosis complex (TSC) to improve diagnosis and treatment level of this disease, and improve the prognosis. MethodsThe clinical data of 54 patients with epilepsy induced by TSC from May, 2012 to May, 2015 were analyzed together with the physical data, clinical presentations, EEG, imaging findings, treatment, prognosis and follow-up. Summarizing the clinical features of epilepsy induced by TSC. ResultsPatients with different epilepsy onset age, whether or not combined spasm, differences in intelligence status were statistically significant (P < 0.05); Patients with different gender, skin lesions, types of seizures, differences in intelligence status were no statistical significance (P > 0.05); Patients with different gender, epilepsy onset age, differences in patients with spasm were statistically significant (P < 0.05); Patients with different family history, skin lesions, types of seizures, differences in patients with spasm were not statistically significant (P > 0.05). Patients with different intelligence status, difference of medication quantity was statistically significant (P < 0.05); Patients with different gender, onset age, family history, skin lesions, whether or not combined spasm, types of seizures, difference of medication quantity was not statistically significant (P > 0.05). ConclusionsEpilepsy is the most common neurological manifestations in TSC, mostly onset in early childhood. Seizure types are different from one to another. Patients can be combined with skin damage and mental retardation. Positive rate of EEG and head imaging examination are high, seizure control rate is low. Patients need long-term follow-up and timely adjustment of treatment. Intelligence status is related to epilepsy onset age, spasm. Patients with spasm are related to different gender, epilepsy onset age. Medication quantity is related to intelligence status.
Objective To explore the efficiency of Vigabatrin for epilepsy in children with Tuberous Sclerosis Complex, and to further research the risk factors related to the outcome after adjunctive use of Vigabatrin. Methods 25 children with TSC and epilepsy treated with Vigabatrin at Children′s Hospital of Fudan University between 2013 and 2015 were included. Clinical characteristics and the effectiveness of other antiepileptic drugs were extracted from the follow-up data. The prevalence of visual field defect was analyzed among the cases. And correlations were made between the responses to Vigabatrin in groups. Results 25 cases, 15 male (60%). 18 cases had response to VGB-adjuvant therapy. Children with epilepsy onset at greater than six months of age were most likely to demonstrateagood response to VGB treatment. And the poorly response of cases showed that 4 had TSC1 mutation. And among the 25 cases, one child had the visual filed defect. Conclusions Vigabatrin as adjunctive therapy showed certain effect in controlling epilepsy in TSC cases, especially infantile spasms and some partial epilepsy. But the side effect of visual filed defect should be cautious. Age-appropriate visual field testing is recommended at baseline and then repeated at intervals in patients exposed to long term Vigabatrin therapy.
