Dietary therapies for epilepsy in low resource settings: challenges and successes

The Ketogenic Diet (KD) is a high fat, low carbohydrate and restricted protein diet which has been used for the treatment of drug resistant epilepsy in children. It is considered the treatment of choice for refractory nonsurgical epilepsy in children. However, despite this being a very useful and relatively simple treatment, children from developing countries have not been able to benefit as much as their counterparts in more privileged settings. In this article, the challenges faced by pediatric neurologists and parents who wish to use the diet in children with refractory epilepsy are discussed, and also the simple low cost innovations which can be used to overcome these challenges are suggested. The evolution from the use of the classic ketogenic diet to the flexible use of the modified Atkins diet in low resource settings will be discussed.

Ketogenic diet: a promising alternative nonpharmacology treatment for pediatric epilepsy

Epilepsy is a syndrome of brain dysfunction induced by the aberrant excitability of certain neurons. Despite advances in surgical technique and anti-epileptic drug in recent years, recurrent epileptic seizures remain intractable and lead to a serious morbidity in the world. The ketogenic diet (KD) is a nonpharmacologic treatment that has been used for refractory epilepsy since 1921. The KD is a high-fat, low-carbohydrate, and restricted protein diet, which is calculated and weighed for each individual patient. The goal of the KD treatment is to bring the brain into a state of ketosis to control seizures. Many studies have shown that ketogenic diet was very useful in controlling refractory epilepsy.

The Effect of Ketoanalogues on Chronic Kidney Disease Deterioration: A Meta-Analysis

The effects of ketoanalogues (KA) on chronic kidney disease (CKD) deterioration have not yet been fully confirmed. To strengthen the evidence of the role of KA in CKD, PubMed and Embase were searched for studies published through February 2019. Effect sizes from ten randomized control trials (RCTs) and two non-RCTs comprising a total of 951 patients were pooled and analyzed. A restricted protein diet supplemented with ketoanalogues (RPKA) was found to significantly delay the progression of CKD (p = 0.008), particularly in patients with an estimated glomerular filtration rate (eGFR) > 18 mL/min/1.73 m2 (p < 0.0001). No significant change in eGFR was found when comparing a very-low-protein diet and a low-protein diet (p = 0.10). In addition, compared with the placebo, RPKA did not cause malnutrition (albumin: p = 0.56; cholesterol: p = 0.50). Moreover, RPKA significantly decreased phosphorous levels (p = 0.001), increased calcium levels (p = 0.04), and decreased parathyroid hormone (PTH) levels (p = 0.05) in patients with eGFR < 18 mL/min/1.73 m2. In conclusion, RPKA could slow down the progression of CKD in patients with eGFR > 18 mL/min/1.73 m2 without causing malnutrition and reverse CKD-MBD in patients with eGFR < 18 mL/min/1.73 m2.

The use of a formula-based ketogenic diet in children with refractory epilepsy

ABSTRACT The ketogenic diet (KD) is a nonpharmacologic treatment that has been used for refractory epilepsy since 1921. The KD is a high-fat, low-carbohydrate, and restricted protein diet, which is calculated and weighed for each individual patient. Introducing and maintaining the diet for a long time remains a challenge. In this study, we evaluated the acceptability, tolerance, and efficacy of a formula-based KD in 10 children with refractory epilepsy. The ketogenic formula tested herein caused only mild KD-related adverse events and adequate adherence. Moreover, 60% of patients had more than 50% seizure frequency reduction and 10% were seizure-free.
