Non-Pharmacological and Non-Surgical Treatment of Refractory Childhood Epilepsy

Sequential Treatment with Modified Atkins Diet and Low Glycemic Index Treatment for Drug-Resistant Epilepsy in Children

OBJECTIVES

The present study was designed to study the efficacy of sequential dietary therapy with a modified Atkins diet (mAD) followed by low glycemic index treatment (LGIT) in treating drug-resistant epilepsy in children.

METHODS

This interventional study was conducted from February 2021 to February 2022 among children aged 6 months to 5 years who had failed to respond to more than two conventional and correctly chosen antiseizure medications. The primary endpoint was the proportion of good responders, that is, children with more than 50% seizure reduction. Secondary outcome measures were the proportion of children with seizure freedom, > 90% seizure reduction, and the nature of parent-reported adverse events.

RESULTS

A total of 45 children were recruited for the study, with 6 children being lost to follow-up at 12 weeks. At 12 weeks, 30 of 39 (76.9%) children were good responders with more than 50% seizure reduction. Of these 30 children, 11 (24.4%) had more than 90% seizure reduction, with 9 (20%) achieving complete spasm freedom. Constipation was the most common side effect of the diet among the enrolled subjects.

CONCLUSION

Clinicians can consider sequential dietary therapy with a mAD in the first month followed by LGIT in the next 2 months for treating children who could not tolerate mAD beyond 1 month.

Ketogenic diet therapies as a non-pharmacological adjuvant in resistant epilepsy: retrospective analysis of adult outpatients in Colombia

Twelve patients between 18 and 53 years of age were included. MAD plus nutritional supplementation was administered to 75% (n = 10) of the participants, one (8.3%) received MAD alone, and 16.7 (n = 2) received Classic Ketogenic Diet (cKD) plus nutritional supplementation. Oral nutritional supplementation, administered in the outpatient setting, provided patients with between 31 and 55% of the total caloric value. In the first month of KDT treatment, 83.3% (n = 10) of patients reduced the number of weekly seizures by 40% (median). At six months of treatment, 75% of patients had at least halved the number of weekly seizures. At 12 months of treatment, the number of weekly seizures had been reduced by 85.7% (median). KDT was well tolerated, and there was no need to discontinue treatment. This study provides real-world information on the use of KDT, particularly MAD in adults, in developing countries. Future studies in larger cohorts will provide further information on different types of KDT, adherence, and patient-reported outcomes.

The role of ketogenic diet in controlling epileptic seizures

Objectives:

To study the role of the ketogenic diet (KD) in controlling seizures in children with medically resistant epilepsy in Saudi Arabia.

Methods:

This retrospective study was conducted in the Pediatric Neurology Clinic at a tertiary care epilepsy center. Thirty-one patients with medically resistant epilepsy were enrolled from 2013 to 2018. The seizure reduction variables were evaluated at 6, 12, 18 and 24 months after enrollment.

Results:

Of the 31 patients, 14 (45.2%) were males and 17 (54.8%) were females. The most common types of seizures were myoclonic seizures and mixed seizures, both of which occurred in 9 (29%) of the participants. Of the participants, 15 (48.4%) had seizures one to 5 times per day. Six months after starting a KD, 2 (6.45%) of participants were seizure-free; 6 (19.35%) were seizure-free after 12 months of treatment.

Conclusion:

The present study highlighted the effectiveness of KD in medically resistant epilepsy children to local population. A larger cohort is warrant to confirm these findings.

Recommendations for the treatment of epilepsy in adult and pediatric patients in Belgium: 2020 update

To guide health care professionals in Belgium in selecting the appropriate antiepileptic drugs (AEDs) for their epilepsy patients, a group of Belgian epilepsy experts developed recommendations for AED treatment in adults and children (initial recommendations in 2008, updated in 2012). As new drugs have become available, others have been withdrawn, new indications have been approved and recommendations for pregnant women have changed, a new update was pertinent. A group of Belgian epilepsy experts (partly overlapping with the group in charge of the 2008/2012 recommendations) evaluated the most recent international guidelines and relevant literature for their applicability to the Belgian situation (registration status, reimbursement, clinical practice) and updated the recommendations for initial monotherapy in adults and children and add-on treatment in adults. Recommendations for add-on treatment in children were also included (not covered in the 2008/2012 publications). Like the 2008/2012 publications, the current update also covers other important aspects related to the management of epilepsy, including the importance of early referral in drug-resistant epilepsy, pharmacokinetic properties and tolerability of AEDs, comorbidities, specific considerations in elderly and pregnant patients, generic substitution and the rapidly evolving field of precision medicine.

Ketogenic diet induces autophagy to alleviate bleomycin-induced pulmonary fibrosis in murine models

AIM OF THE STUDY

Ketogenic diet (KD) has been identified as an effective strategy in treating multiple diseases. KD is capable of inducing autophagy which is an important therapeutic target for pulmonary fibrosis (PF). This study aimed to investigate the effect of KD treatment on PF progression. Materials and Methods: Intratracheal instillation of bleomycin (BLM, 5 mg/kg) to establish PF model in male Kunming mice fed either KD or standard diet. The survival of mice was recorded every day for 3 weeks. The pulmonary tissues were weighed on day 21 and the pulmonary index was calculated. The histopathological changes of pulmonary tissues were analyzed by hematoxylin and eosin staining and Masson staining, and the collagen deposition by hydroxyproline assay. Then the content of proinflammatory factors in pulmonary tissues was measured using enzyme-linked immunosorbent assay, and the expression of profibrogenic cytokines, autophagy markers and PI3K/AKT/mTOR pathway-related proteins in pulmonary tissues using western blotting or immunohistochemistry. Results: KD treatment significantly restored the BLM-induced increase of pulmonary index and had a tendency to increase the survival rate of PF mice. Furthermore, KD treatment restored the BLM-induced damage of alveolar structure, infiltration of inflammatory cells and collagen deposition and decreased hydroxyproline content. In addition, the BLM-induced secretion of tumor necrosis factor-alpha, interleukin-6 and interleukin-1β and expression of transforming growth factor β1, phospho-Smad2/3, connective tissue growth factor, α-smooth muscle actin and collagen type III alpha 1 chain were inhibited by KD. KD treatment also up-regulated the expression of light chain 3 II/I and Beclin1 and down-regulated the expression of p62, phospho-AKT, phospho-mTOR and phospho-p70S6K, suggesting that KD induced autophagy and suppressed the BLM-induced activation of PI3K/AKT/mTOR signaling pathway. Conclusions: These findings indicate that KD can alleviate PF in vivo by regulating autophagy and PI3K/AKT/mTOR signaling pathway, which provides a novel therapeutic strategy for PF.
