EUROPEAN JOURNAL O F PAEDIATRIC NEUROLOGY
childhood stroke, participated in the study. Population-based control-group for perinatal stroke consisted of 150 and for childhood stroke of 84 healthy individuals. DNA testing for MTHFR C677T and A1298C mutations was performed, genotypes were determined by PCR using specific primers. Association analysis (p-values with Fisher exact test, odds ratios with 95% confidence intervals) was performed using Terminal software. Results: The 677T allele carrier status (p=0.9, OR=1.0) did not show relevance as a genetic risk factor for perinatal stroke. An interesting observation was the fact that minor allele frequency of A1298C was higher in healthy controls than in patients with either perinatal (p=0.08, OR=0.63) or childhood (p=0.14, OR=0.6) AIS. On the other hand, minor allele frequency of C677T demonstrated a weak association with childhood AIS (p=0.09, OR=1.7, 95% CI: 0.9– 3.2). Conclusion: Our data support the hypothesis that functional MTHFR polymorphism C677T may represent a genetic risk factor for childhood AIS, representing 1.7-times higher risk. The A1298C polymorphism was not found as genetic risk factor for perinatal nor for childhood stroke.
P203 - 2949 Seizures persistence’s prognosis in children with arterial ischemic stroke L. Shalkevich, O. Lvova, M. Lukashchuk, A. Dolmatova, A. Kudlatch. Department of Pediatric Neurology, Belarusian Medical Academy of Post-Graduate Education, Minsk, Belarus Objective: To investigate clinical and electroencephalographic features of seizures during acute and recovery periods of arterial ischemic stroke (AIS) in children. Methods: Type of study: case series. Inclusion criteria: Children 0–15 y.o. with seizures during AIS’s debut. We identified the type of episodes and EEG features in acute and recovery periods after one year. Results: 152 children with AIS were examined. Seizures occurred during the acute period of stroke in 39 (25.7%) cases and antiepileptic therapy was prescribed for all of them. Generalized seizures type was registered in 56.4% (n=22), focal type in 23% (n=9), focal type with secondary generalization – in 20.6% (n=8) children. Epileptiform activity was registered in 31% (n=9) patients. Disorganized changes on background EEG without signs of paroxysmal activity were predominant in most children – 75.9% (n=22) as well as background activity was normal only in 13.8% (n=4) of them. In the recovery period seizures persisted in 10.5% (n=16). Generalized seizures of acute period pass to recovery period in 27.2% (n=6, RR=0.56 95%CI 0.3–1.0), and focal seizures with secondary generalization – in 75% (n=6, RR=2.75 95%CI 1.2–6.0). Seizures accompanied by epileptiform activity on EEG during acute period persisted in the recovery period in 55.6% (n=5, RR=2.7 95%CI 1.1– 6.1), without activity – in 30% (n=9, RR=0.5 95%CI 0.2–1.1). At the same time generalized seizures of acute period combined with epileptiform activity on EEG persist in recovery period in 50% (n=2, RR=2.2 95%CI 0.6–8.3), without it – in 22.2% (n=4, RR=0.6 95%CI 0.2–1.7). Conclusion: The presence of epileptiform activity on EEG and the development of focal with secondary generalization seizures type in children with AIS and seizures in the acute period increase the risk of seizure persistence in the recovery period in spite of antiepileptic therapy have been prescribed.

31 had hemorrhagic stroke). The patients were between infants to 14 years old. We were observation all patients along year. 5 children (6.41%) were died: 2 children after IS, 3 – after HS. Since one year 21 patients (28.77%) were healthy and 52 (71.23%) had outcomes symptoms (motor abnormalities, epilepsy, mental retardation (include speech and cognitive problems)). 44 children (60.27%) had problems with motor function, 27 (36.99%) – seizures, 34 (46.57%) – mental retardation. 18 patients (24.66%) had one outcome symptom, 15 children (20.55%) – had two symptoms, 19 patients (26.02%) – had three symptoms together. Results: Children with motor abnormalities since one year in the acute period had hemoglobin 104.70±2.66 g/l, the average level of hemoglobin in group without motor problems in future was 114.60±4.11 g/l (p<0.05). In the group of children who had seizers since one year level of hemoglobin in acute period was 101.52±3.5 g/l to compared with group of children without seizers – 112.83±2.95 g/l (p<0.05). Patients who had mental retardation since one year in the acute period of stroke had hemoglobin 96.71±2.59 g/l and children without mental problem in future had 119.05±2.87 g/l in the acute period (p<0.05). Conclusion: Children who had outcome symptoms since one year after stroke had a lower hemoglobin level in the acute period than children without neurological problems in future.
P205 - 2992 Dyslipidemia as the possible risk factor for arterial ischemic stroke in children O. Lvova, I. Gavrilov, I. Astryuhina, E. Orlova, O. Kenzina, Y. Kuznetsov. Child Neurology Unit, Clinic Paediatric City Hospital 9, Departament of Clinical Psychology and Psychophysiology, Ural Federal University, Yekaterinburg, Russia Background: Arterial Ischemic Stroke (AIS) in children is very rare and can be caused by huge number of diseases. Dyslipidemia seems to be the risk factors of AIS in children. But interaction between dyslipidemia and pediatric AIS is not investigated thoroughly. Objective: To investigate the incidence and the possible variants of dyslipidemias in children with Arterial Ischemic Stroke (AIS). Methods: Type of study: case series. Inclusion criteria: 76 boys or girls under the age of 15 y.o. with AIS’s debut and confirmed by brain CT (MRI) scan; slavic origin; informed consent form. We identified cholesterol level in 76; HDL, Triglycerides in 37; LDL, VLDL in 32 children (mmol/l was the unit for all data) and KA in AIS acute period (during first 3 days). Results: We found dyslipidemias in more than quarter cases. The average level for exceeding indicators were: triglycerides 2.5±0.21 (n=10), cholesterol 5.62±0.11 (n=20), LDL 3.55±0.2 (n=6), VLDL 1.29±0.12 (n=6), KA 3.9±0.2 (n=19). The low level of HDL was in 15 cases (0.75±0.05). In 24 cases we identified isolated hypo-α-cholesterolemia, in 18 – IIa Fredrickson phenotype, in 6 – IV and in 2 patients IIb Fredrickson phenotype. Conclusion: We assume dyslipidemias to have the diagnostic value in early life stroke’s debut. The maximum possible set of lipid and lipoproteins must be assigned and the reason of dyslipidemias has to be investigated. Detection of dyslipidemia may become a starting point for therapy and secondary prevention in those patients.
