摘　　要：Background Medium-chain triglyceride ketogenic diet(MCTKD)is previously less commonly used in China.This study was aimed to assess the efficacy and safety of the modified MCTKD in the treatment of drug-resistant epilepsy in Chinese patients.Methods Patients with drug-resistant epilepsy were enrolled to receive treatment with modified MCTKD in Guangdong Sanjiu Brain Hospital during December 2020 and September 2022.The modified MCTKD contained fat that provided 50–70%of the total energy,as well as proteins and carbohydrates that provided 20–30%and 20%of energy,respectively.The fat component was composed of 20–30%medium-chain triglycerides(MCTs)and 30–40%long-chain triglycerides.The efficacy and safety of the diet were assessed at 1,3 and 6 months.Results A total of 123 patients aged 2.5 to 65 years,were included in this study.The response rates at 1,3 and 6 months were 49.6%,43.1%,and 30.9%,respectively.The seizure freedom rates at 1,3 and 6 months were 12.2%,10.6%,and 6.5%,respectively.The retention rates at 1,3 and 6 months were 98.4%,65.0%and 33.3%respectively.Side effects occurred in 21.14%of patients,which were predominantly gastrointestinal symptoms such as abdominal pain,diarrhea,vomiting,and constipation,and most of them resolved after dietary adjustments.A total of 82 patients(66.7%)discontinued the treatment with the reason of refusing to eat(8.1%),poor efficacy(35.0%),poor compliance(4.9%),and inability to follow-up(9.8%).Only 4 patients(3.3%)withdrew the diet due to side effects.Conclusions The modified MCTKD with MCTs providing 20–30%of energy has a good safety in patients with drug-resistant epilepsy,but its effectiveness needs to be enhanced.Further modifications of MCTKD with an optimal energy ratio are required to achieve a better efficacy and safety.
