ObjectiveTo assess the effects of the Coronavirus disease 2019 (COVID-19) epidemic on patients with infantile epileptic spasms syndrome and their parents through an online questionnaire survey.MethodsThis study was a cross-sectional study conducted from May to June 2022. The questionnaire focused on seizure attacks, medical visits, and the mental health assessment of parents. ResultsA total of 67 patients with infantile epileptic spasms syndrome were included in this study. During the epidemic, 25.37% of the patients experienced increased spasms, and 73.13% of the patients had limited commercial availability of anti-seizure medications, mainly vigabatrin and clobazam. All patients had difficulty seeking medical services, and about 73.13% of them used telemedicine service. In addition, 31.34% of parents felt anxious, and 73.14% had different degrees of depressive symptoms. ConclusionThe difficulty in seeking medical services, limited commercial availability of anti-seizure medications, and the anxiety and depressive states of parents during the COVID-19 pandemic aggravate the difficulty in management of patients with infantile epileptic spasms syndrome. Improvement of the health care system and medication management strategy, as well as reasonable use of telemedicine service, may help solve this problem.
ObjectiveTo explore the differences in the detection of vigabatrin-associated brain abnormalities on MRI by different MRI sequences, so as to further guide the clinical understanding of VABAM and improve the appropriate imaging sequences. MethodsA total of 353 patients with infantile spasm or epileptic spasm who were admitted to the Epilepsy Center of Yuquan Hospital of Tsinghua University from January 2020 to January 2023 were retrospectively included. MRI was performed in 131 cases, including 3D T1, T2, T1- fluid-attenuated inversion recovery sequence (FLAIR) images, DWI and ADC sequences, of which 65 cases taking VGB. We aim to evaluate the detection of vigabatrin-associated brain abnormalities on MRI by different MRI sequences in these children. Results Among the 65 patients, VABAM was detected in 23 cases, the detection rate was 35.4%. The average dosage of vigabatrin was 100.73±35.54 mg/(kg·d). The positive detection rates of VABAM were 95.7% in DWI sequence, 26.1% in ADC sequence, 21.3% in FLAIR sequence, 4.3% in T2 sequence and 0 in T1 sequence. The detection rate of ADC sequence was significantly different from DWI sequence and T1 sequence, but not from T2 sequence and FLAIR group. ConclusionDWI sequence has irreplaceable advantages in the detection rate of VABAM. Therefore, for patients with infantile spasm and epileptic spasm who take vigabatrin, we should try our best to add DWI sequence scanning to improve the positive detection rate and avoid clinical symptoms, so as to avoid further brain damage.
Objective To explore the evaluation value of burden of amplitudes and epileptiform discharges score (BASED) in the efficacy of adrenocorticotropic hormone (ACTH) combined with magnesium sulfate therapy for infantile epileptic spasms syndrome (IESS). Methods Retrospective collection the clinical and EEG data of 124 patients admitted to the Dongguan Maternal and Child Health Care Hospital from 2015 to 2023, who were diagnosed with IESS and treated with ACTH combined with magnesium sulfate. According to whether there were epileptic seizures 14 days after ACTH treatment, the patients were divided into two groups: non seizure group (n=74 cases) and seizure group (n=50 cases). The BASED system was used to evaluate the relationship between changes in EEG before and after ACTH treatment and clinical efficacy in both groups. The analysis of electroencephalogram included: ① abnormally high amplitude background waves, ② >3 spike foci , ③ grouped multifocal spikes, ④ paroxysmal voltage attenuation. ResultThe control rate of ACTH combined with magnesium sulfate in the treatment of IESS was 59.7% (74/124), and there was no statistically significant difference in the control rate among children with different etiologies (P=0.09). The BASED score suggests that the overall response rate of electroencephalogram (EEG) in infants with epileptic spasm syndrome after treatment was 57.2%. The EEG remission rate in the seizure control group was 81% (60/74), while in the uncontrolled group was 22% (11/50). The EEG remission rate in the seizure control group was significantly higher than that in the uncontrolled group after treatment (P<0.001), and the EEG score was closely related to clinical efficacy (Spearman correlation coefficient rp=0.601, P<0.001). ConclusionThe BASED score is related to clinical efficacy, and it can provide a quantitative basis for evaluating the efficacy of ACTH combined with magnesium sulfate in the treatment of IESS.
Infantile epileptic spasm syndrome (IESS) is an age-dependent epileptic encephalopathy that onset within 3 ~ 12 months. Commonly used Anti-seizure medications (ASMs) have poor efficacy, low long-term control rate and high recurrence rate, and often leave behind sequelae such as developmental delay/intellectual disability, and autism spectrum disorders. At present, the first-line recommended treatments for IESS are Adrenocorticotropic hormone (ACTH), adrenocortical hormone and vigabatrin. If ineffective, other ASMs, ketogenic diets, and surgical treatments can be tried. This article will provide a review of the current status and related clinical applications of IESS treatment.
