Summary
The ketogenic diet (KD) may initially affect vascular health in children with epilepsy, but these changes in lipids and arterial function appear reversible after two years. Long-term KD effects on vascular atherogenic processes require further investigation.
Area of Science:
- Pediatric Neurology
- Metabolic Disorders
- Vascular Biology
Background:
- The ketogenic diet (KD) is a recognized treatment for drug-resistant childhood epilepsy.
- Long-term effects of the high-fat, low-carbohydrate KD on vascular atherogenic and biochemical markers are not well understood.
Purpose of the Study:
- To evaluate the long-term vascular and biochemical effects of the ketogenic diet in children with epilepsy.
- To assess changes in carotid artery intima-media thickness (cIMT), distensibility, compliance, and blood lipid profiles.
Main Methods:
- Longitudinal study of 26 children on KD at 1 year and 13 at 2 years.
- High-resolution ultrasound assessed cIMT, distensibility, and compliance.
- Analyzed blood lipids (HDL-C, LDL-C, TC, apoA, apoB) and hsCRP.
Main Results:
- A decrease in carotid distensibility and increases in LDL-C, apoB, and lipid ratios were observed at 3 and 12 months.
- These vascular and lipid changes were not statistically significant at 24 months.
- No significant changes in cIMT, BMI, or hsCRP were detected.
Conclusions:
- Initial alterations in lipids and arterial function during the first year of KD treatment seem reversible.
- The long-term (24 months) KD treatment did not show significant adverse vascular or biochemical changes in this cohort.

Diabetic ketoacidosis (DKA) is a metabolic emergency characterized by hyperglycemia, ketonemia, and metabolic acidosis. It results from severe insulin deficiency and an excess of counterregulatory hormones, leading to uncontrolled lipolysis, ketogenesis, and widespread electrolyte and fluid disturbances.Pathophysiology The central event in DKA is a profound loss of insulin action. Without insulin, glucose uptake in insulin-dependent tissues is impaired, while hepatic glucose production...

30
DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic...

2.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

01:26Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
382
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

2.7K
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
