Data on the impact of the ketogenic diet (KD) on children’s growth remain controversial. Here, we retrospectively investigated the occurrence of linear growth retardation in 34 children (47% males; age range: 2−17 years) diagnosed with drug-resistant epilepsy (DRE; n = 14) or glucose transporter type 1 deficiency syndrome (GLUT1-DS; n = 20) who had been treated with the KD for 12 months. The general characteristics of children with and without growth retardation were also compared. All participants received a full-calorie, traditional KD supplemented with vitamins, minerals, and citrate. Most children (80%; 11/14 in the DRE subgroup and 16/20 in the GLUT1-DS subgroup) treated with the KD did not show growth retardation at 12 months. Although participants with and without delay of growth did not differ in terms of baseline clinical characteristics, dietary prescriptions, or supplementation patterns, marked ketosis at 12 months tended to occur more frequently in the latter group. Altogether, our results indicate that growth retardation may occur in a minority of children treated with the KD. However, further research is required to identify children at risk and to clarify how increased ketones levels may affect endocrine pathways regulating growth during KD administration.
Objective The objective of this study was to evaluate care needs, emotional and behavioral changes, and parental stress indices in a cohort of pediatric patients with epilepsy with neurocognitive and emotional comorbidities at the time of the coronavirus disease 2019 (COVID-19) pandemic. Methods This is a prospective observational study involving pediatric patients with epilepsy with neurocognitive and emotional comorbidities. Included patients were admitted to our hospital between August 2019 and February 2020 for epilepsy and neuropsychiatric assessment, and Child Behavior Checklist (CBCL) questionnaires were filled in by parents. Those patients and their families accepted to participate in a phone follow-up visit in April–May 2020 and to refill CBCL and Parenting Stress Index–Short Form (PSI-SF) questionnaires. Descriptive statistics for demographic and clinical data, CBCL questionnaire scores before and during the COVID-19 pandemic, and PSI-SF scores have been computed. Moreover, results of a short phone survey on the psychological burden during COVID lockdown have been reported. Results This study provides the parental-proxy report of emotional and behavioral profile changes of 23 pediatric patients with epilepsy and neurocognitive and emotional comorbidities during the COVID-19 pandemic. Concerns for therapy monitoring at the time of lockdown emerged in 43% of families, and 30% of patients showed worries for an altered contact with the referring medical team. Patients with neurocognitive comorbidities were more likely to exhibit behavioral problems, especially externalizing problems compared with patients with a diagnosis of anxiety/depression. Conclusion Our data suggest the importance to monitor disease trajectory and behavior and affective symptoms with telehealth strategies to provide effective care to patients and their families.
Introduction Glucose Transporter Type I Deficiency Syndrome ( GLUT 1 DS ) classical symptoms are seizures, involuntary movements, and cognitive impairment but so far the literature has not devoted much attention to the last. Methods In our retrospective study involving 25 patients with established GLUT 1 DS diagnosis, we describe the cognitive impairment of these patients in detail and their response to the ketogenic diet in terms of cognitive improvement. Results We outlined a specific cognitive profile where performance skills were more affected than verbal ones, with prominent deficiencies in visuospatial and visuomotor abilities. We demonstrated the efficacy of ketogenic diet ( KD ) on cognitive outcome, with particular improvement tin total and verbal IQ ; we found that timing of KD introduction was inversely related to IQ outcome: the later the starting of KD , the lower the IQ , more notable nonverbal scale (verbal IQ correlation coefficient −0.634, p ‐value = 0.015). We found a significant direct correlation between cognition and CSF /blood glucose ratio values: the higher the ratio, the better the cognitive improvement in response to diet (from T0–baseline evaluation to T1 on average 18 months after introduction of KD ‐: TIQ correlation coefficient 0.592, p ‐value = 0.26; VIQ correlation coefficient 0.555, p ‐value = 0.039). Finally, we demonstrated that a longer duration of treatment is necessary to find an improvement in patients with “severely low ratio.” Conclusion Our results were consistent with the hypothesis that timing of the diet introduction is a predictive factor of cognitive outcome in these patients, confirming that earlier initiation of the diet may prevent the onset of all GLUT 1 DS symptoms: epilepsy, movement disorders, and cognitive impairment.
• Ketogenic diet efficacy is now described in large case series, with adequate diet compliance and side effects control. • Ketogenic diet is far from being attempted as a first line therapy. Its availability varies worldwide. What is New: • New pharmacological targets such as mitochondrial permeability transition and new epileptic syndromes and etiologies responding to the diet such as refractory status epilepticus are being pointed out. • Ketogenic diet can function at its best when used as a tailor-made therapy. Fine tuning is crucial.
