Objective: The aim of this study is to assess bone mineral status in children with epilepsy, on different antiepileptic drugs (AEDs) regimen, using dual-energy X-ray absorptiometry (DXA) and routine biochemical bone markers.
Patients And Methods: This is observational prospective controlled cohort study, conducted at Mansoura University Children Hospital, from January 2014 to June 2015. In this study, we had 152 participants with ages 3-13 years, 70 children diagnosed with epilepsy and 82 were controls. Children classified into two groups according to the duration of treatment, Group 1 children maintained on AEDs for 6-24 months, Group 2 children ≥24 months. Bone mineral density (BMD) measured by DXA and biochemical markers includes serum calcium, phosphorus, alkaline phosphatase (ALP), and parathyroid hormone (PTH).
Results: In this study, we found that the serum level of calcium and phosphate were significantly low ( > 0.05) in total cases versus control. We found that the serum level of and ALP and PTH were significantly high ( > 0.05) in total cases versus control. Regarding the DXA markers, there was a significant decrease of BMD and Z-score for the total body and lumbar area in the total cases versus control ( > 0.05).
Conclusion: The present study showed that all AEDs (new and old) affect bone mineral status in children receiving therapy for more than 6 months, altering both biochemical markers (serum calcium, phosphorus, ALP, and PTH) and radiologic markers (BMD assessed using DXA). Children on AEDs for a longer duration (≥2 years) showed more severe side effects on BMD. Children receiving multiple AEDs are more prone to altered bone mineral status, especially with long duration of therapy. The study also highlights the role of DXA as a safe noninvasive method to assess BMD in children on long-term AEDs.

FRAX, a risk calculator that provides individualized 10-year probabilities of hip and major osteoporotic fracture, has been widely used for fracture risk assessment since its launch in 2008. It is now incorporated into very many guidelines worldwide to inform osteoporosis management. In this review, we explore the development of FRAX and how it enhances fracture risk prediction as compared to use of bone mineral density alone, as well as approaches to utilizing FRAX in determining intervention and assessment thresholds.

Alzheimer's disease (AD) and osteoporosis (OP) pose distinct but interconnected health challenges, both significantly impacting the aging population. AD, a neurodegenerative disorder characterized by memory impairment and cognitive decline, is primarily associated with the accumulation of abnormally folded amyloid beta (Aβ) peptides and neurofibrillary tangles in the brain. OP, a skeletal disorder marked by low bone mineral density, involves dysregulation of bone remodeling and is associated with an increased risk of fractures.

Bone mineral density (BMD) measured by T-score is strongly associated with bone health, but research on its association with metals in humans body remains limited. To investigate the relationship between metal exposure and BMD, numbers of 159 participants in eastern China were studied. Urine and blood samples were collected and levels of 20 metals in the samples were measured using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS).

Fracture healing is a complex process during which the bone restores its structural and mechanical integrity. Collagen networks and minerals are the fundamental components to rebuild the bone matrix in callus. It has been recognized that bone quality could be impaired during aging.

Purpose: Thyroid hormones have a catabolic effect on bone mineral homeostasis. Hypothyroid patients have shown changes in bone mineral density with increased risk for osteoporosis and bone fractures. Radiomorphometric parameters on panoramic images are good indicators of bone mineral density.
