The Effect of Levetiracetam on Lipid Profile in Children
Study Details
Study Description
Brief Summary
Levetiracetam is a widely prescribed antiseizure medication in epileptic children due to an estimated better safety profile and easy accessibility. There is limited and contradicting data about the effect of levetiracetam on serum lipid metabolisms, especially in epileptic children. The aim of our study was to evaluate the effect of levetiracetam therapy on lipid metabolism in euthyroid non-obese epileptic children. In this case-control study, the investigators recruited 37 epileptic children receiving levetiracetam monotherapy for at least 12 months and 54 healthy controls. All the participants were euthyroid and within normal nutritional status limits for their age. Fasting blood samples were obtained for serum thyroid-stimulating hormone (TSH), free triiodothyronine, free thyroxine, total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides, Triglyceride/HDL Index, uric acid, CRP, and transaminases at the administration. The investigators would like to show if epileptic children with levetiracetam monotherapy are susceptible to lipid metabolism alterations.

Detailed Description
A total of 37 pediatric epileptic patients (children = 16, adolescents = 21) and 54 healthy control (children = 17, adolescents = 37) were enrolled to the study. Participants admitted to the pediatric neurology outpatient clinic of Ataturk City Hospital from October 2020 to October 2021 were recruited to this observational case-control study.
The pediatric neurologist and pediatric endocrinologist evaluated all the participants' medical data to determine their medical history and physical examination. Retrospectively, all the participants' age, gender, anthropometric assessments, BMI (body weight/height2), pubertal development staging, laboratory workup (thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), total cholesterol (TC), aspartate aminotransferase (AST), alanine aminotransferase (ALT), uric acid, CRP) noted from the medical records. Height and weight measurements of the participants were made with a digital Harpenden stadiometer by the same person.
Seizure and epilepsy types of patients were categorized according to recommendations of the International League Against Epilepsy, 2017.
The degree of seizure control was categorized 'controlled' if they were seizure-free for ≥1 year, 'partially controlled' if the seizures' intervals were longer than seven days but shorter than 30 days, and 'uncontrolled' if the seizures occurred several times a day or at intervals shorter than seven days.
The Puberty Development Scale categorized in boys with testicular volume (testicular volume measured with a prader orchidometer) greater than 4 milliliters were considered pubertal. And for girls with breast development at Tanner stage 2 (breast development with an elevation of breast and papilla; enlargement of the areola) and above were considered pubertal.
All participants were established 'euthyroid' by evaluating TSH (mIU/L), fT3 (pmol/L), fT4(pmol/L). For participants aged 4-11.9 years, normal thyroid hormone levels were 0.2- 3.0 mIU/L for TSH, 4.6-8.2 pmol/L for fT3, and 13.8-35.3 pmol/L for fT4.For participants aged older than 11.9 years, published thyroid hormone values of Campbell et al. were used to determine normal thyroid hormone levels23. The physical examinations, blood tests (TSH, fT3, fT4, TG, HDL, LDL, total cholesterol, AST, ALT, uric acid, CRP) for each enrolled patient and control subject were obtained the time after overnight fasting (at least 10 hours) at the outpatient clinic's admission. Published lipid levels of the National Cholesterol Education Program guidelines were used for all participants 24. The TG/HDL index was calculated as the ratio of TG (mg/dL) to HDL (mg/dL) value.
The informed consent form was obtained from parents of all the children and healthy controls. The regional Ethics Committee approved the current study (2021/186-08/09/21). Statistical Analysis Statistical analyses were performed using the SPSS software version 25.0 (SPSS Statistics for Windows, 2017). The sample size was calculated by using the statistical software (G*Power version 3). The variables were investigated using visual (histogram, probability plots) and analytical methods (Kolmogorov-Smirnov) to determine whether they are normally distributed. Descriptive analyses were presented (using frequencies for ordinal variables) and using mean and standard deviation. Continuous variables were compared among the two groups by using an independent t-test. If the variable did not have a normal distribution, the Mann-Whitney U test was applied for the groups. A Chi-Square test was used to examine the association between categorical variables. A 5% type- I error level was used to infer statistical significance.
