1 方法

1.3 神經(jīng)電生理檢查 患兒入我院后常規(guī)行1～2次長程VEEG(意大利EB PLUS-32導(dǎo)視頻腦電圖系統(tǒng))和同步肌電監(jiān)測，監(jiān)測時間>4 h，記錄至少1個完整的清醒-睡眠周期。

2 結(jié)果

2.2.2 發(fā)作癥狀學(xué)特點 經(jīng)VEEG監(jiān)測到成串痙攣9例，孤立痙攣8例，成串和孤立痙攣1例。痙攣表現(xiàn)為屈曲型13例，伸展型2例，混合型1例，輕微痙攣(無明顯軀干和肢體收縮)2例，其中合并強直痙攣3例；對稱痙攣16例，不對稱痙攣2例。同時還監(jiān)測到全面性發(fā)作7例，其中不典型失神3例，強直發(fā)作和肌陣攣發(fā)作各2例；部分性發(fā)作3例。

2.3 神經(jīng)電生理特點

2.3.1 發(fā)作間期神經(jīng)電生理特點 18例患兒中EEG為典型高度失律4例(圖1A)；無典型高度失律14例，其中多灶和廣泛性放電12例，一側(cè)多灶放電2例。10例異常放電在顳區(qū)或顳額區(qū)明顯(圖1B)，4例可見尖波或棘波節(jié)律(圖1C)。

Fig 1 Interictal and ictal EEG findings in late-onset epileptic spasm

Notes A: Interictal EEG showed hypsarrhythmia in a 2-year old male patient diagnosed as late-onset West syndrome; B: Interictal EEG showed multifocal discharges could be identified obviously in temporofrontal regions in an 8-year old male patient; C: Interictal EEG showed general spike wave rhythm in a 6-year old male patient diagnosed as Lennox-Gastaut syndrome; D: Ictal EEG showed clustered epileptic spasms in a 2-year old male patient diagnosed with late-onset West syndrome (L1R1, left and right deltoid muscle)

2.4 其他檢查 18例均行頭顱影像學(xué)檢查，結(jié)構(gòu)異常8例，其中腦多發(fā)軟化灶5例，腦萎縮3例。10例行血、尿串聯(lián)質(zhì)譜檢查，均未見明顯異常。1例行ARX基因目標區(qū)域捕獲二代測序，結(jié)果為陰性。

2.6 電-臨床綜合征分類 根據(jù)腦電圖和臨床表現(xiàn)，8例符合電-臨床綜合征診斷，其中晚發(fā)型West綜合征4例，Lennox-Gastaut綜合征4例。

ObjectiveTo explore the clinical manifestations and electroencephalogram (EEG) features, causes and the effect of ketogenic diet (KD) for children diagnosed as pharmacoresistant late-onset epileptic spasms (LOES).MethodsThe clinical and EEG characteristics and the effect of antiepileptic drugs (AEDs) in 18 children with LOES were analyzed retrospectively. The effectiveness of one week, one month and three months after KD therapy for 8 children with pharmacoresistant LOES was evaluated. Results Eighteen children including 13 boys and 5 girls aged from 2 to 10 years with the median age of 6 years and 6 months were included. The onset age of epileptic seizures ranged from 1 year to 8 years with the median age of 3 years. The course of epilepsy ranged from 1 to 72 months with the median age of 9 months. The first seizure type was epileptic spasms in 4 cases and other seizure types in 14 children (77.8%). Interictal EEG showed classic hypsarrhythmia in 4 cases and no hypsarrhythmia in 14 cases (77.8%) of which multifocal discharges could be dentified obviously in temporofrontal regions. Developmental delay presented in all cases and 7 cases (44.4%) were symptomatic epilepsies, of which the commonest causes were central nervous system infection and perinatal insults, while 11 cases (61.1%) had unknown causes. Four patients fulfilled the entry criteria of late-onset West syndrome and 4 patients were diagnosed as Lennox-Gastaut syndrome. Eighteen patients were followed up for 3 to 24 months during AEDs treatment and the majority of the children were on valproate in monotherapy (n=2) or in combination with other AEDs (n=16) at the last follow up. Fourteen patients (77.8%) were diagnosed with pharmacoresistant epilepsy and 8 cases of them received KD therapy. Greater than 50% seizure reduction was achieved in 2 of 8 cases at one week, 3 of 8 cases at 1 month and 5 cases (62.5%) at 3 months after KD therapy. Seizure free was achieved in 1 of 8 case at one month and 3 cases (37.5%) at 3 months after KD therapy. Eight patients treated with KD was well tolerated and adverse effects were not found.ConclusionChildren with LOES not only occur in West syndrome, but also in other epileptic encephalopathy. Interictal EEG does not show classic hypsarrhythmia in most patients generally. Most LOES are refractory epilepsy and the KD is a safe and potentially effective method of treatment for children with LEOS.
