Abstract
BACKGROUND Calcitonin gene-related peptide (CGRP), implicated in migraine pain, also possesses bone anabolic properties, which leads to the possibility that monoclonal antibodies targeting CGRP (anti-CGRPs) might increase the risk of bone density abnormalities. OBJECTIVE The objective of this study was to explore bone mineral density abnormalities in a cohort of migraine patients treated with anti-CGRPs. METHODS This was a single-center, cross-sectional, cohort study including migraine patients who underwent a densitometry assessment during anti-CGRP treatment. We assessed the frequency of osteopenia or osteoporosis (OSTEO+ status), defined as a bone mineral density T-score of -1 to -2.5, and <-2.5 standard deviations from the young female adult mean, respectively. Additionally, the association of OSTEO+ status with anti-CGRP treatment duration and primary osteoporosis' risk factors was investigated using logistic regression models. RESULTS Data from 51 patients (43 female, mean age 46 ± 13.9 years) were evaluated. The mean duration of anti-CGRP treatment was 15.7 (±11.8) months. Twenty-seven patients (53%) were OSTEO+ (n = 22 osteopenia; n = 5 osteoporosis). In the final model, menopause [odds ratio 11.641 (95% confidence interval 1.486-91.197), p = 0.019] and anti-seizure drug use [odds ratio 12.825 (95% confidence interval 1.162-141.569), p = 0.037] were associated with OSTEO+ status. CONCLUSIONS In our cohort of migraine patients, no evidence of an association between anti-CGRP treatment duration and an increasing risk of bone mineral density abnormalities was found. However, these findings are preliminary and necessitate further longitudinal research with larger cohorts and extended follow-up to be validated.

Front Nutr 2024; 11:1439279. [PMID: 39279896 PMCID: PMC11392846 DOI: 10.3389/fnut.2024.1439279] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2024] [Accepted: 08/19/2024] [Indexed: 09/18/2024] Open
Abstract
Introduction The prevalence of vitamin D deficiency and vitamin D levels in patients with epilepsy (PWE) were systematically evaluated, and the differences between subgroups were analyzed. Method We identified all articles investigating the prevalence of vitamin D deficiency in patients with epilepsy from the database established in March 2024 from PubMed, Web of Science, and Embase. We divided them into anti-seizure medication (ASM) interventions and non-ASM interventions according to whether or not someone used ASM. Results A total of 68 articles were included. The prevalence of newly diagnosed epilepsy was 50.2% (95% CI: 38.7-61.7%), and the prevalence after ASM intervention was 47.9% (95% CI: 40-55.9%), including 7,070 patients with epilepsy. Subgroup and meta-regression analyses were performed according to the diagnostic criteria, economic development level, region, age, ASM treatment, and other factors. The results showed that the differences were not significant. In addition, the vitamin D content of epilepsy patients (18.719 ng/mL) was lower than that of healthy people (20.295 ng/mL). Conclusion The prevalence of vitamin D deficiency in patients with epilepsy is very high. Still, the related factors have little effect on the high prevalence of vitamin D in epilepsy, and ASM intervention can reduce the vitamin D content in patients with epilepsy. Therefore, it is emphasized that monitoring vitamin D levels is part of the routine management of patients with epilepsy. Systematic review registration The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO). (registration number CRD42023493896). https://www.crd.york.ac.uk/PROSPERO/ # myprospero.

Drug-induced osteoporosis and mechanisms of bone tissue regeneration through trace elements. J Trace Elem Med Biol 2024; 84:127446. [PMID: 38615498 DOI: 10.1016/j.jtemb.2024.127446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 03/30/2024] [Accepted: 04/03/2024] [Indexed: 04/16/2024]
Abstract
Osteoporosis is associated with an imbalance in bone formation, with certain drugs used in disease treatment being implicated in its development. Supplementation with trace elements may contribute to bone regeneration, offering an alternative approach by enhancing bone mineral density (BMD) and thereby thwarting the onset of osteoporosis. This review aims to assess the mechanisms through which trace elements such as copper (Cu), iron (Fe), selenium (Se), manganese (Mn), and zinc (Zn) are linked to increased bone mass, thus mitigating the effects of pharmaceuticals. Our findings underscore that the use of drugs such as aromatase inhibitors (AIs), proton pump inhibitors (PPIs), antiretrovirals, glucocorticoids, opioids, or anticonvulsants can result in decreased BMD, a primary contributor to osteoporosis. Research indicates that essential elements like Cu, Fe, Se, Mn, and Zn, through various mechanisms, can bolster BMD and forestall the onset of the disease, owing to their protective effects. Consequently, our study recommends a minimum daily intake of these essential minerals for patients undergoing treatment with the aforementioned drugs, as the diverse mechanisms governing the effects of trace elements Cu, Fe, Mn, Se, and Zn facilitate bone remodeling.

Abstract
Epilepsy is a prevalent neurological disorder among women globally, often requiring long-term treatment. Hormonal fluctuations in women with epilepsy (WWE) can have reciprocal effects on epilepsy and antiseizure medications (ASMs), posing significant challenges for WWE. Notably, WWE commonly experience endocrine alterations such as thyroid dysfunctions, low bone metabolism, and reproductive hormone irregularities. On the one hand, the presence of hormones in women with epilepsy affects their susceptibility to epilepsy as well as the metabolism of antiseizure medications in various ways. On the other hand, epilepsy itself and the use of antiseizure medications impact the production, secretion, and metabolism of hormones, resulting in low fertility, increased risk of pregnancy complications, negative offspring outcomes, and so on. In order to develop more precise treatment strategies in the future, it is necessary to comprehend the explicit relationships between hormones, epilepsy, and antiseizure medications, as well as to elucidate the currently known mechanisms underlying these interactions.

Abstract
CASE An 18-year-old autistic boy with seizure disorder had a 4-month-old hip injury with a similar right hip injury 6 months earlier. X-rays revealed an ununited fracture neck femur on the left and a malunited fracture neck femur on the right hip. Magnetic resonance imaging indicated preserved head vascularity. Valgus osteotomy and double-angle plate fixation of both hips were performed at an interval of 2 months. CONCLUSION Delayed presentation bilateral neck fractures are rare. X-rays showed healed fractures with no avascular necrosis in both hips at 2-year 6-month follow-up. Valgus osteotomy is ideal and relevant for osteosynthesis in selected ununited femur neck fractures.

Abstract
OBJECTIVE The present study investigated the possible impacts of anti-epileptic drugs (AEDs) on trabecular and cortical bone in the mandible. STUDY DESIGN Fractal dimension (FD) and the radiomorphometric parameters of mandibular cortical width (MCW), panoramic mandibular index (PMI), and mandibular cortical index (MCI) were assessed on 497 dental panoramic radiographs (DPRs) of patients in the case group and controls. AEDs were compared according to 3 generations, duration of use, and patient age and sex. RESULTS FD of the angle and body of the mandible and MCW were significantly lower in the case group than in the control group (P < .001). FD values in the ramus and angle were lower in first-generation and third-generation AEDs than in second-generation drugs (P ≤ .011). FD in the mandibular body was lower in first-generation and second-generation AED users than in third-generation drugs (P = .017). Drug use for at least 1 year resulted in significantly lower values for all FDs and MCW values and more class 3 MCI assessments than short-duration use, but PMI was higher with more than 1 year of AED use (P ≤ .020). Age and sex had no significant effects. CONCLUSIONS AEDs caused significant changes in bone compared with controls in some FD values, MCW, and MCI. The effect of drug generation is pronounced in trabecular bone. Anti-epileptic drug use for more than 1 year had a greater effect than short-term use.

[PMID: 37088260 DOI: 10.1016/j.phrs.2023.106780] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/12/2023] [Accepted: 04/21/2023] [Indexed: 04/25/2023]
Abstract
The ketogenic diet is known to be a possible adjuvant treatment in several medical conditions, such as in patients with severe or drug-resistant forms of epilepsy. Its use has recently been increasing among adolescents and young adults due to its supposed weight-loss effect, mediated by lipolysis and lowered insulin levels. However, there are still no precise indications on the possible use of ketogenic diets in pediatric age for weight loss. This approach has also recently been proposed for other types of disorder such as inherited metabolic disorders, Prader-Willi syndrome, and some specific types of cancers. Due to its unbalanced ratio of lipids, carbohydrates and proteins, a clinical evaluation of possible side effects with a strict evaluation of growth and nutritional status is essential in all patients following a long-term restrictive diet such as the ketogenic one. The prophylactic use of micronutrients supplementation should be considered before starting any ketogenic diet. Lastly, while there is sufficient literature on possible short-term side effects of ketogenic diets, their possible long-term impact on growth and nutritional status is not yet fully understood, especially when started in pediatric age.

Abstract
The term osteomalacia (OM) refers to a series of processes characterized by altered mineralization of the skeleton, which can be caused by various disorders of mineral metabolism. OM can be genetically determined or occur due to acquired disorders, among which the nutritional origin is particularly relevant, due to its wide epidemiological extension and its nature as a preventable disease. Among the hereditary diseases associated with OM, the most relevant is X-linked hypophosphatemia (XLH), which manifests in childhood, although its consequences persist into adulthood where it can acquire specific clinical characteristics, and, although rare, there are XLH cases that reach the third or fourth decade of life without a diagnosis. Some forms of OM present very subtle initial manifestations which cause both considerable diagnosis and treatment delay. On occasions, the presence of osteopenia and fragility fractures leads to an erroneous diagnosis of osteoporosis, which may imply the prescription of antiresorptive drugs (i.e., bisphosphonates or denosumab) with catastrophic consequences for OM bone. On the other hand, some radiological features of OM can be confused with those of axial spondyloarthritis and lead to erroneous diagnoses. The current prevalence of OM is not known and is very likely that its incidence is much higher than previously thought. Moreover, OM explains part of the therapeutic failures that occur in patients diagnosed with other bone diseases. Therefore, it is essential that clinicians who treat adult skeletal diseases take into account the considerations provided in this practical review when focusing on the diagnosis and treatment of their patients with bone diseases.

Definition, Assessment, and Management of Vitamin D Inadequacy: Suggestions, Recommendations, and Warnings from the Italian Society for Osteoporosis, Mineral Metabolism and Bone Diseases (SIOMMMS). Nutrients 2022; 14:nu14194148. [PMID: 36235800 PMCID: PMC9573415 DOI: 10.3390/nu14194148] [Citation(s) in RCA: 31] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Revised: 09/23/2022] [Accepted: 09/30/2022] [Indexed: 11/07/2022] Open
Abstract
In the recent years, both the prescriptions of serum 25(OH)D levels assay, and vitamin D supplementation are constantly increasing, as well as the costs to be incurred relating to these specific aspects. As in many other countries, the risk of vitamin D deficiency is particularly high in Italy, as recently confirmed by cohort studies in the general population as well as in patients with metabolic bone disorder. Results confirmed the North-South gradient of vitamin D levels described among European countries, despite the wide use of supplements. Although vitamin D supplementation is also recommended by the Italian Medicine Agency for patients at risk for fragility fracture or for initiating osteoporotic medication, the therapeutic gap for osteoporosis in Italy is very high. There is a consistent proportion of osteoporotic patients not receiving specific therapy for osteoporosis following a fragility fracture, with a poor adherence to the recommendations provided by national guidelines and position paper documents. The failure or inadequate supplementation with vitamin D in patients on antiresorptive or anabolic treatment for osteoporosis is thought to further amplify the problem and exposes patients to a high risk of re-fracture and mortality. Therefore, it is important that attention to its possible clinical consequences must be given. Thus, in light of new evidence from the literature, the SIOMMMS board felt the need to revise and update, by a GRADE/PICO system approach, its previous original recommendations about the definition, prevention, and treatment of vitamin D deficiency in adults, released in 2011. Several key points have been here addressed, such as the definition of the vitamin D status: normality values and optimal values; who are the subjects considered at risk of hypovitaminosis D; opportunity or not of performing the biochemical assessment of serum 25(OH)D levels in general population and in subjects at risk of hypovitaminosis D; the need or not to evaluate baseline serum 25(OH)D in candidate subjects for pharmacological treatment for osteoporosis; how and whether to supplement vitamin D subjects with hypovitaminosis D or candidates for pharmacological treatment with bone active agents, and the general population; how and whether to supplement vitamin D in chronic kidney disease and/or chronic liver diseases or under treatment with drugs interfering with hepatic metabolism; and finally, if vitamin D may have toxic effects in the subject in need of supplementation.

Abstract
Osteoporosis is a systemic bone-resorbing disease that easily causes subsequent risk of fracture. Hence, the substantial physical burden of osteoporosis makes it an important public health issue. Seborrheic dermatitis (SD) is a chronic, recurrent, inflammatory skin disease. Despite the advances in medication for treating osteoporosis, identifying undiagnosed osteoporosis patients is still challenging. Since osteoporosis and SD share a similar pathobiology, e.g. inflammation and hormonal imbalance, we aimed to investigate whether the existence of SD increases osteoporosis risk by using the Taiwan National Health Insurance Research Database. A total of 7831 patients aged 18-50 years with SD and a control group of 31 324 patients without SD matched by age, gender, Charlson Comorbidity Index, and index date at a ratio of 1:4 during 1996-2010 were recruited in the study. To measure the cumulative incidence and compare the hazard ratios of osteoporosis between each group, the Kaplan-Meier method and Cox proportional hazard regression models were utilized. It was found that 0.98% of SD patients had osteoporosis. Compared to the non-SD group, the SD group had a 5.95-fold higher osteoporosis risk after adjustment for variables. The impact of SD on osteoporosis risk was largest in the female and young age groups. In addition, the presence of hyperlipidemia, hyperthyroidism, and epilepsy synergistically increased osteoporosis incidence in the SD group. This first large cohort study demonstrated an association between SD and osteoporosis. Since the effect on bone health in SD patients with concomitant diseases is largest in early life, diet or lifestyle recommendations as well as regular bone examinations are advised during follow-up of SD.

Abstract
Increasing number of studies shows significant reductions in bone mineral density in patients with epilepsy treated with enzyme-inducing anti-seizure medications (EIASM), valproic acid, and newer anti-seizure medications (ASM). ASM seems to be a specific risk factor for the development of osteoporosis affecting 11%-31% of patients with epilepsy and leads to 2 to 6 times increased risk of fractures compared to the background population. Treatment with ASM clearly contributes to epilepsy-associated bone disease. Yet, the exact pathophysiological mechanism has not been established; however, several hypotheses were suggested, especially in relation to EIASM. As the long-lasting medical treatment, often in polytherapy, has shown negative effects on bone health, it indicates the need for guidelines for the prevention and management of bone disease to be included in the follow-up of patients with epilepsy. An algorithm for following bone status during the treatment has been suggested based on Danish national guidelines.

Abstract
Objectives Intellectual disability (ID) and epilepsy are independent risk factors for osteoporosis. Diverse predisposing factors influence this, for example in ID, genetics and poor nutrition and in epilepsy, anti‐seizure medication (ASM). Around 25% people with ID have epilepsy, majority treatment resistant. ASMs polypharmacy is common. However, little is known about the bone‐related characteristics of this vulnerable group. A prospective observational cohort study of bone profile across a community ID Epilepsy service was undertaken to understand this. Materials & Methods Participants were on minimum 2 years of ASMs. Baseline demographics, epilepsy data, bone metabolism biomarkers, bone mineral density (BMD) and vitamin D levels were collected. Doses needed to correct vitamin D insufficiency/deficiency were calculated. Results At baseline, of 104 participants, 92 (90.2%) were vitamin D insufficient/deficient. Seventy‐six (73.1%) had a DEXA scan, 50 of whom—in the osteopaenic/osteoporotic range. DEXA scores between ambulant and non‐ambulant patients were significantly different (p = .05) but not for ID severity. A high alkaline phosphatase (ALP) predicted lower vitamin D levels. Borderline significance (p = .06) in calcium levels between normal and high ALP was identified. There were no significant associations between parathyroid hormone, inorganic phosphate and magnesium levels, with vitamin D status or DEXA hip T‐scores. Normalizing vitamin D levels (mean 101.4 nmol/L) required an average of 1951IU cholecalciferol daily. Conclusions Vitamin D deficiency is highly prevalent in people with ID and epilepsy treated with ASMs impacting likely on their bone health. Screening with vitamin D levels, ALP and DEXA in this group should be pro‐actively and routinely considered.

Complications associated with the use of enzyme-inducing and non-enzyme-inducing anti-seizure medications in the Japanese population: A retrospective cohort study. Epilepsy Behav 2022; 129:108610. [PMID: 35231856 DOI: 10.1016/j.yebeh.2022.108610] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 01/05/2022] [Accepted: 02/01/2022] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Enzyme-inducing anti-seizure medications (EIASMs) may contribute to the development of complications such as fracture and cardiovascular disease. The objective of the study was to determine whether the use of EIASMs is associated with a higher risk of fracture and cardiovascular outcome in young Japanese patients with epilepsy. METHOD Adult patients diagnosed with epilepsy and initiated a monotherapy with an anti-seizure medication (ASM) between 2008 and 2018 were included in the study. The primary outcomes were the occurrence of acute myocardial infarction (AMI) or stroke. The secondary outcome was fracture. We performed a propensity score-matched analysis (1:1) to control for imbalances in patient characteristics, and the matched hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models. RESULT Of the 7115 eligible patients, 626 (8.79%) initiated treatment with EIASMs. The median age of the patients was 44 years (interquartile range: 31-54 years), and 56.2% were male. Propensity score matching generated 626 matched pairs of patients treated with EIASMs and non-EIASMs. There were no significant differences in the risk of stroke (EIASM group: n = 28[4.47%], non-EIASM group: n = 22[3.51%], HR: 1.47, 95% CI: 0.79-2.72, p = 0.22) or fracture (EIASM group: n = 7[1.12%], non-EIASM group: n = 5[0.80%], HR: 1.00, 95% CI: 0.29-3.45, p = 1.00) between the two groups. The hazard ratio for the occurrence of AMI could not be calculated due to the small number of events (EIASM group: n = 0[0.00], non-EIASM group: n = 2[0.32]). SIGNIFICANCE Our cohort study did not find increased risk of the occurrence of stroke, AMI, or fracture hospitalization with the use of enzyme-inducing ASMs. Although the findings suggested that exposure to EIASMs does not appear to increase the risk of complications in young patients, caution should be taken as patients with epilepsy tend to take medication in the long run.

Abstract
BACKGROUND During seizures, injury of the upper extremities may occur. Standardized guidelines are deficient for diagnosis and perioperative care. METHODS PubMed, Embase, Cochrane, Scopus, and Web of Science databases were systematically screened using predefined search terms. RESULTS Of the 59 patients included, 36 (61.0%) involved a posterior shoulder dislocation. Associated fractures were observed in 34 (57.6%) cases with surgical procedures performed in 30 (50.8%) patients. Functional outcomes were reported in 44 patients, with over half (23 of 44, [52.2%]) endorsing range of motion deficits. CONCLUSION Standardized guidelines, to guarantee timely management of injury in post-seizure patients, are needed with a customized treatment approach that accommodates the various aspects of their condition.

How Do Drugs Affect the Skeleton? Implications for Forensic Anthropology. BIOLOGY 2022; 11:biology11040524. [PMID: 35453723 PMCID: PMC9030599 DOI: 10.3390/biology11040524] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 02/21/2022] [Accepted: 03/18/2022] [Indexed: 01/10/2023]
Abstract
Simple Summary Forensic anthropologists analyze human remains to assist in the identification of the deceased, predominantly by assessing age-at-death, sex, stature, ancestry and any unique identifying features. Whilst methods have been established to create this biological profile of the skeleton, these may be influenced by a number of factors. This paper, for the first time, provides an overview from a reading of the clinical and pharmacological literature to explore whether the intake of drugs can affect the skeleton and whether these may have implications for forensic anthropology casework. In effect, drugs such as tobacco, heroin, and prescription medications can alter bone mineral density, can increase the risk of fractures, destroy bone and changes to the dentition. By considering how drugs can affect the skeleton, forensic anthropologists can be aware of this when attempting to identify the deceased. Abstract Forensic anthropologists rely on a number of parameters when analyzing human skeletal remains to assist in the identification of the deceased, predominantly age-at-death, sex, stature, ancestry or population affinity, and any unique identifying features. During the examination of human remains, it is important to be aware that the skeletal features considered when applying anthropological methods may be influenced and modified by a number of factors, and particular to this article, prescription drugs (including medical and non-medical use) and other commonly used drugs. In view of this, this paper aims to review the medical, clinical and pharmacological literature to enable an assessment of those drug groups that as side effects have the potential to have an adverse effect on the skeleton, and explore whether or not they can influence the estimation of age-at-death, sex and other indicators of the biological profile. Moreover, it may be that the observation of certain alterations or inconsistencies in the skeleton may relate to the use of drugs or medication, and this in turn may help narrow down the list of missing persons to which a set of human remains could belong. The information gathered from the clinical and medical literature has been extracted with a forensic anthropological perspective and provides an awareness on how several drugs, such as opioids, cocaine, corticosteroids, non-steroidal anti-inflammatory drugs, alcohol, tobacco and others have notable effects on bone. Through different mechanisms, drugs can alter bone mineral density, causing osteopenia, osteoporosis, increase the risk of fractures, osteonecrosis, and oral changes. Not much has been written on the influence of drugs on the skeleton from the forensic anthropological practitioner perspective; and this review, in spite of its limitations and the requirement of further research, aims to investigate the current knowledge of the possible effects of both prescription and recreational drugs on bones, contributing to providing a better awareness in forensic anthropological practice and assisting in the identification process of the deceased.

Abstract
Adolescence is a fundamental period for the formation of the skeleton, because is the stage in which bones grow more in both size and strength, laying a solid foundation for the future health of the skeleton. Any condition interfering with optimal peak bone mass accrual can increase fracture risk later in life. Up to 80% of peak bone mass is genetically determined while the remaining 20% is modulated by environmental factors that, if deleterious, may result in low bone mineral density (BMD) and an increased risk of fracture. The preferred test to assess bone health is dual-energy x-ray absorptiometry (spine or total body less head) using Z scores instead of T scores, even though in short stature or growth delay, should be used the height Z-score. The correction of risk factors is the first treatment for low BMD in children and adolescents. It's necessary having a correct lifestyle for preserving bone health: a proper nutrition, an adequate physical weight-bearing activity and avoidance of alcohol intake and tobacco smoke. Bisphosphonates could be used in children who sustained osteoporotic fractures, impairing quality of life, when spontaneous recovery is low for the persistence of osteoporosis risk factors. This clinical review discusses factors affecting bone health during childhood and adolescence and deals with diagnosis and treatment of low bone mass or osteoporosis in this age group.

Impact of carbamazepine on vitamin D levels: A meta-analysis. Epilepsy Res 2021; 178:106829.

Abstract
PURPOSE There are longstanding concerns about the impact of enzyme-inducing anti-seizure medications (ASMs) on vitamin D, an important molecule in both bone metabolism and inflammation pathways. The relationship between chronic use of carbamazepine and vitamin D levels has been studied, but no comprehensive review to inform practitioners and policymakers is currently available. We performed a meta-analysis on studies that measured 25-hydroxyvitamin D (25OHD) levels in persons taking carbamazepine to determine whether this drug significantly reduces circulating 25OHD. PRINCIPAL RESULTS From a literature search of the terms "carbamazepine" and "vitamin D", we identified 12 studies that measured 25OHD levels in persons on carbamazepine monotherapy groups and controls. Persons taking carbamazepine had significantly lower 25OHD levels than persons not taking carbamazepine. The average 25OHD levels of carbamazepine-treated patients across all studies was 21.8 ng/mL (IQR 15.4,26.0) whereas 25OHD levels of control subjects was 28.0 ng/mL (IQR 20.8,30.4). The weighted difference of means was 4.00 ng/mL of 25OHD. Neither age nor sex nor duration of carbamazepine therapy had a significant impact on this finding. The effect was similar irrespective of whether the comparator group consisted of healthy controls or epilepsy patients taking non-inducing medications. MAJOR CONCLUSIONS Carbamazepine use is associated with a reduction of 25OHD levels. In combination with other literature establishing the problematic metabolic effects of carbamazepine, this meta-analysis provides additional evidence in favor of the use of alternative ASMs as first-line agents. At minimum, vitamin D supplementation should be strongly considered for patients prescribed carbamazepine.

Abstract
Background Anti-seizure medication (ASM) treatment is one of the significant risk factors associated with abnormal vitamin D status in epilepsy patients. Multiple studies have shown that adult epilepsy patients can exhibit vitamin D deficiency. However, there are few reports investigating pediatric epilepsy patients. In this study, we aimed to identify risk factors related to hypovitaminosis D in pediatric epilepsy patients in Thailand. Methods A cross-sectional retrospective cohort study was conducted in 138 pediatric epilepsy patients who received anticonvulsants from April 2018 to January 2019. Demographic data, seizure types, puberty status, physical activity, duration, and types of anti-seizure medications were analyzed. Patients with abnormal liver function, abnormal renal function, and who received vitamin D supplements or ketogenic diet containing vitamin D were excluded. Levels of serum vitamin D (25(OH)D) were measured. Results All 138 subjects were enrolled, the age ranged from 1.04 – 19.96 years; (mean = 9.65 ± 5.09), the mean serum 25(OH) D level was 26.56 ± 9.67 ng/ml. The prevalence of vitamin D deficiency was 23.2% and insufficiency was 47.8% respectively. Two risk factors—puberty status (OR 5.43, 95% CI 1.879-15.67) and non-enzyme-inhibiting ASMs therapy (OR 3.58, 95% CI 1.117-11.46)—were significantly associated with hypovitaminosis D, as shown by multivariate analyses. Conclusions Our study reports the high prevalence of hypovitaminosis D in pediatric epilepsy patients in Thailand despite being located in the tropical zone. These findings can guide clinicians to measure vitamin D status in pediatric epilepsy patients particularly when they reach puberty and/or are using non-enzyme-inhibiting ASMs therapy. Early detection of vitamin D status and prompt vitamin D supplementation can prevent fractures and osteoporosis later in life. Trial registration TCTR20210215005 (http://www.clinicaltrials.in.th/).

Abstract
There have been a number of reports that chronic antiepileptic drug (AEDs) therapy is associated with abnormal bone and calcium metabolism, osteoporosis/osteomalacia, and increased risk of fractures. Bony adverse effects of long term antiepileptic drug therapy have been reported for more than four decades but the exact molecular mechanism is still lacking. Several mechanisms have been proposed regarding AEDs induced bone loss; Hypovitaminosis D, hyperparathyroidism, estrogen deficiency, calcitonin deficiency. Transforming growth factor-β (TGF- β) is abundant in bone matrix and has been shown to regulate the activity of osteoblasts and osteoclasts in vitro. All isoforms of TGF- β are expressed in bone and intricately play role in bone homeostasis by modulating estrogen level. Ovariectomised animal have shown down regulation of TGF- β in bone that could also be a probable target of AEDs therapy associated bone loss. One of the widely accepted hypotheses regarding the conventional drugs induced bone loss is hypovitaminosis D which is by virtue of their microsomal enzyme inducing effect. However, despite of the lack of enzyme inducing effect of certain newer antiepileptic drugs, reduced bone mineral density with these drugs have also been reported. Thus an understanding of bone biology, pathophysiology of AEDs induced bone loss at molecular level can aid in the better management of bone loss in patients on chronic AEDs therapy. This review focuses mainly on certain new molecular targets of AEDs induced bone loss.

Abstract
Objective To develop an index assessing the risks of low energy fractures (LEF) in patients prescribed antiepileptic drugs (AED) by exploring five previously suggested risk factors; age, gender, AED-type, epilepsy diagnosis and BMI. Methods In a population-based retrospective open cohort study we used real world data from the Electronic Health Register (EHR) in Region Kalmar County, Sweden. 23 209 patients prescribed AEDs at any time from January 2008 to November 2018 and 23 281 matching controls were followed from first registration in the EHR until the first documented LEF, disenrollment (or death) or until the end of the study period, whichever came first. Risks of LEF measured as hazard rate ratios in relation to the suggested risk factors and in comparison to matched controls were analyzed using Cox regression. The index was developed using a linear combination of the statistically significant variables multiplied by the corresponding regression coefficients. Results Data from 23 209 patients prescribed AEDs and 2084 documented LEFs during a follow-up time of more than 10 years resulted in the Kalmar Epilepsy Fracture Risk Index (KEFRI). KEFRI = Age-category x (1.18) + Gender x (-0.51) + AED-type x (0.29) + Epilepsy diagnosis-category x (0.31) + BMI-category x (-0.35). All five previously suggested risk factors were confirmed. Women aged 75 years and older treated with an inducing AED against epilepsy and BMIs of 25 kg/m2 or below had 48 times higher LEF rates compared to men aged 50 years or younger, treated with a non-inducing AED for a condition other than epilepsy and BMIs above 25 kg/m2. Conclusion The KEFRI is the first weighted multifactorial assessment tool estimating risks of LEF in patients prescribed AEDs and could serve as a feasible guide within clinical practice.

Abstract
Lower-extremity injuries may occur during seizures. There is a lack of standardized guidelines when diagnosing and planning perioperative care. Databases were systematically screened using predefined search terms. Of the 13 patients included, seven (53.8%) involved bilateral femoral neck fractures. Associated fractures were observed in all cases with surgical intervention performed in eight (61.5%) patients. Eleven patients reported functional outcomes, with over a quarter (three of 11, [27.3%]) endorsing mild range of motion deficits or issues with ambulation. Post-seizure patients may require standardized diagnostic protocols to ensure prompt management with a specialized treatment approach that accommodates the nuances of their condition.

Sun L, Zheng W, Liu QD, Ge L. Valproic Acid Protects Chondrocytes from LPS-Stimulated Damage via Regulating miR-302d-3p/ITGB4 Axis and Mediating the PI3K-AKT Signaling Pathway. Front Mol Biosci 2021; 8:633315. [PMID: 33968981 PMCID: PMC8100442 DOI: 10.3389/fmolb.2021.633315] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Accepted: 02/04/2021] [Indexed: 01/10/2023] Open
Abstract
Background: Osteoarthritis (OA) is one of the most common degenerative joint diseases characterized by increased apoptosis and autophagy deficiency. The investigation was performed to examine the effect of valproic acid (VPA) and molecular mechanism related to miR-302d-3p/ITGB4 axis in OA. Methods: The OA clinical samples were obtained from the GEO database to analyze differentially expressed genes. An in vitro OA model was mimicked by LPS in CHON-001 cells. Autophagy-related genes were downloaded from the HADb website, and potential drugs were mined using the CTD website. The upstream factors of ITGB4 were predicted with bioinformatics analysis, which was validated by luciferase activity assay and RIP assay. Cell viability and apoptosis were evaluated using CCK-8 and flow cytometry. The expression levels, including ITGB4, miR-302d-3p, and autophagy-/PI3K-AKT pathway-related markers, were measured by qRT-PCR or/and western blot. Results: Our results showed that miR-302d-3p inhibited cell viability and promoted apoptosis of LPS-treated CHON-001 cells by targeting ITGB4. VPA treatment remarkably alleviated LPS-stimulated injury in CHON-001 cells. The inhibitory effect of VPA on LPS-stimulated damage in CHON-001 cells was weakened by miR-302d-3p overexpression, while it was intensified because of ITGB4 upregulation. Mechanistically, VPA treatment induced a significant decrease in the levels of p-PI3K and p-AKT in LPS-stimulated CHON-001 cells through regulating miR-302d-3p/ITGB4 axis. Conclusion: Overall, VPA treatment may ameliorate LPS-induced injury on chondrocytes via the regulation of miR-302d-3p/ITGB4 pair and the inactivation of the PI3K-AKT pathway.

The effects of antiepileptic drugs on bone health: A systematic review. Epilepsy Res 2021; 173:106619. [PMID: 33774428 DOI: 10.1016/j.eplepsyres.2021.106619] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 03/09/2021] [Accepted: 03/18/2021] [Indexed: 11/21/2022]
Abstract
PURPOSE Epilepsy may be treated with antiepileptic drugs (AEDs), which have been reported to decrease bone mineral density (BMD). Current data is conflicting and variable, and little is known with regard to how duration of AED use or specific AEDs, such as CYP-450 enzyme-inducing (EIAEDs) versus non-enzyme inducing (NEIAEDs) drugs affect BMD. We sought to systematically review BMD changes due to AED use to identify trends in reporting. METHODS A literature search via Medline (PubMed), EMBASE, and Cochrane databases was performed. Peer-reviewed articles were identified that reported on BMD measurements in conjunction with AEDs. RESULTS Twenty-six studies met inclusion criteria. Long-term therapy was shown across multiple, well-controlled studies to have the most significant BMD loss. Carbamazepine had the most frequent reporting of unfavorable effects on bone health and Lamotrigine seemed to show the most bone-protective qualities. Serum biochemical markers of bone turnover did not significantly correlate with measured BMD changes. CONCLUSION The present study provides evidence that long-term AED therapy is the most significant risk factor for BMD loss. Furthermore, there was little compelling evidence to support that EIAEDs, as a class, were more harmful to bone than NEIAEDs, which has been previously suggested in multiple studies. Early clinical concern for significant loss of BMD may not be warranted as lower BMD was less likely to be observed during the initial years of AED therapy. Furthermore, serum markers of bone turnover are not clinically reliable in assessing BMD changes in patients taking AEDs.

Abstract
Calcium is responsible for the effectiveness of various processes, and its supply in the diet is necessary for the normal function of the human body. Apart from being an important component of the skeleton, calcium also helps maintain the structure of cell organelles and regulates intracellular and extracellular fluid homeostasis. This review presents the nutritional and health factors that affect the bioavailability of calcium. Physiological conditions and factors such as pregnancy, infancy, menopause, old age, hormones, growth factors associated with calcium metabolism, diseases limiting its absorption, and intestinal microbiota are distinguished among endogenous factors. Although the calcium supply in the body is genetically conditioned and specific to each person, its qualitative and quantitative composition can be modified by external factors. The exogenous factors include dietary modifications with particular nutrients and pharmacological treatment. Adequate calcium levels increase bone protection and prevent osteoporosis, a disease involving low mineral bone mass.

Abstract
OBJECTIVES We aimed to investigate fracture risk associated with anticonvulsant use in a population-based sample of men and women. METHODS Data from 1,458 participants (51.8% women) with a radiologically confirmed incident fracture (cases) were compared to 1,796 participants (46.5% women) without fracture (controls). Lifestyle factors, medication use and medical history were self-reported. Associations between anticonvulsant use and fracture were explored using binary logistic regression following adjustment for confounders. RESULTS In men, fracture cases and controls differed in age, smoking history, education, alcohol use, and gonadal hormone supplementation. In women, fracture cases and controls differed by previous fracture history, alcohol use, physical activity levels and use of anti-fracture agents. After adjustment for age, pooled anticonvulsant use was associated with a 3.4-fold higher risk of fracture in men and a 1.8-fold higher risk in women. Following further adjustments for confounders these patterns persisted; a 2.8-fold higher fracture risk in men and a 1.8-fold higher fracture risk in women. CONCLUSIONS Anticonvulsant use was associated with increased fracture risk, independent of demographic, lifestyle, medical and medication related factors. While further studies exploring potential underlying mechanisms are warranted, regular monitoring of bone health in anticonvulsant users with risk factors may be useful.

Carbamazepine adversely altered the pituitary-testicular axis with resultant reproductive dysfunctions than levetiracetam or carbamazepine-levetiracetam adjuvant treatment in male Wistar rat. Andrologia 2020; 52:e13871.

Abstract
This study investigated the on-toward reactions of individual or adjunctive treatment with carbamazepine (CBZ) and levetiracetam (LEV) on the pituitary-testicular axis in male rats. Twenty-four male Wistar rats were randomised into 4 groups (n = 6) and received daily intraperitoneal (i.p) treatment of normal saline (0.1 ml/day); CBZ (25 mg/kg i.p); LEV (50 mg/kg i.p); or combination of CBZ (12.5 mg/kg) and LEV (25 mg/kg) for 4 weeks. The serum concentration of luteinising hormone (LH), follicle-stimulating hormone (FSH), and testosterone was determined. Also, the seminal profile and histomorphological status of the testis were determined. Data were analysed using descriptive and inferential statistics. The control and test groups were compared using Student's t test, analysis of variance (ANOVA), and Student-Newman-Keuls post hoc analysis where appropriate, while the results presented as mean ± SEM in graphs or tables. The level of significance was taken at p < .05. The percentage motility, viability, and concentration of FSH decreased significantly in all the treatment groups, while the testis was presented with various forms of histomorphological aberrations. This study concludes that CBZ, and CBZ + LEV adjunctive treatments alter the pituitary-testicular axis with evidence of hormonal deregulation and alteration in the reproductive functions' indices, while LEV treatment remains the safest.

Abstract
Although antiepileptic drugs (AEDs) are mainstay of the treatment of epilepsy, they are associated with significant adverse effects. The present study reviews the adverse effects of AEDs on some of the nutrition-related issues, including bone health, body weight, glucose and lipid metabolism, vitamin homeostasis, antioxidant defense system, and pregnancy. This paper also provides some nutritional recommendations for people with epilepsy. Patients with epilepsy should be regularly evaluated with regard to their nutrition status and any possible nutritional problems. Daily intake of adequate amounts of all nutrients from various sources should be encouraged, especially for vulnerable groups such as children, adolescents, elderly, and pregnant women. When necessary, preventative or therapeutic supplementation with appropriate micronutrients could be helpful. Graphical abstract.

Abstract
BACKGROUND Interpretation of pediatric bone mineral density by dual energy absorptiometry (DXA) requires adjustment for height (Ht). This is often not easily obtainable in nonambulant subjects. AIMS To investigate the feasibility of using DXA images to evaluate measurements of Ht, sitting height (SH), and leg length (LL). METHODOLOGY A total of 2 observers performed measurements of Ht, SH, and LL on 3 separate occasion using DXA digital images in 125 children. Intraclass correlation and relative technical error of measurement (rTEM) were performed to assess reliability of repeated measurements. In 25 children, Ht and SH were measured in clinic on the same day and Bland-Altman analysis was performed to compare DXA measured Ht, SH, LL with clinic measurements for these 25 children. RESULTS Intraclass correlation for DXA based Ht, SH, and LL measurements ranged from 0.996 to 0.998 (p < 0.0001). rTEM of Ht, SH, and LL for observer 1 was 0.0016%, 0.002%, and 0.0034%, respectively. rTEM of Ht, SH, and LL between observer 1 and 2 was 0.0047%, 0.0049%, and 0.0087%, respectively. Mean difference between clinic and DXA measurements from Bland-Altman plots were +0.57 cm (95% confidence interval [CI] -0.54 to +1.68) for Ht, +1.33cm (-1.60 to +4.24) for SH, and -0.76cm (-3.88 to +2.37) for LL. CONCLUSIONS Our study demonstrated for the first time that Ht, SH, and LL in children can be measured very precisely using DXA images. Ht can be measured accurately. We believe this may be a convenient method to obtain Ht measurements to allow size adjustment of DXA bone mineral density in immobile children with chronic conditions.

Abstract
Hepatic cytochrome P450 enzyme induction is associated with certain antiepileptic drugs (AEDs) and may result in hypocalcaemia secondary to vitamin D deficiency. We report a case of a 44-year-old man with a history of epilepsy, who presented with breakthrough seizures after having previously been seizure-free for 11 years. Investigations revealed severe hypocalcaemia with a corrected calcium of 1.7 mmol/L. His phenytoin dose was increased, and he was started on calcium supplementation. He was discharged with a corrected calcium level of 2.05 mmol/L but was readmitted 1 week later with further seizures and a corrected calcium of 1.89 mmol/L. 25-hydroxyvitamin D was low. AED-induced hypocalcaemia was suspected, which had been made paradoxically worse by the increase in phenytoin dose. Alfacalcidol was prescribed and he was switched from phenytoin to levetiracetam with resolution of hypocalcaemia and no further seizures. The authors recommend screening for calcium and vitamin D deficiency in patients on enzyme-inducing AEDs.

Abstract
PURPOSE Numerous studies have shown that the risk of fracture is increased by long-term antiepileptic drugs (AEDs). Valproic acid (VPA) is one of the most commonly used AEDs. In this meta-analysis, we aimed to assess the effects of VPA on bone mineral density (BMD) and bone metabolism. METHODS PubMed, Embase, Cochrane and Web of Science databases were searched from inception to January 2019 for articles focusing on the effects of VPA on BMD and bone metabolism in adults or children. A meta-analysis was performed using RevMan 5. 3 software. RESULTS 18 studies were included in the meta-analysis. The BMD of lumber spine (MD= -0.06, 95%CI: -0.09 to -0.03, P < 0.0001) and femoral neck (MD= -0.05, 95% CI= -0.08 to -0.01, P = 0.02) was markedly decreased in the VPA group compared to healthy controls. Serum bone-specific alkaline phosphatase (BALP) level (SMD = 0.85, 95% CI: 0.30-1.40, P = 0.002) was notably increased in the VPA group compared to healthy groups. In the child group, the serum parathyroid hormone (PTH) level was higher than in healthy groups (SMD= -0.22, 95% CI: -0.40 to -0.04, P = 0.02); besides, the serum 25-hydroxy vitamin D3 (25(OH)D3) level was decreased (SMD= -0.22, 95% CI: -0.40 to -0.04, P = 0.02), while no significant alteration of these parameters was noted in the adult VPA group (P ≥ 0.05). CONCLUSIONS VPA may reduce the BMD of lumbar spine and femoral neck in patients with epilepsy while increasing the serum BALP level. Serum PTH level are increased and serum 25(OH)D3 level decreased in children with epilepsy treated with VPA. These parameters were unaltered in adults.

Abstract
Osteoporosis is a prevalent osteodegenerative disease and silent killer linked to a decrease in bone mass and decline of bone microarchitecture, due to impaired bone matrix mineralization, raising the risk of fracture. Nevertheless, the process of bone matrix mineralization is still an unsolved mystery. Osteoporosis is a polygenic disorder associated with genetic and environmental risk factors; however, the majority of genes associated with osteoporosis remain largely unknown. Several signaling pathways regulate bone mass; therefore, dysregulation of a single signaling pathway leads to metabolic bone disease owing to high or low bone mass. Parathyroid hormone, core-binding factor α-1 (Cbfa1), Wnt/β-catenin, the receptor activator of the nuclear factor kappa-B (NF-κB) ligand (RANKL), myostatin, and osteogenic exercise signaling pathways play pivotal roles in the regulation of bone mass. The myostatin signaling pathway increases bone resorption by activating the RANKL signaling pathway, whereas osteogenic exercise inhibits myostatin and sclerostin while inducing irisin that consequentially activates the Cbfa1 and Wnt/β-catenin bone formation pathways. The aims of this review are to summarize what is known about osteoporosis-related signaling pathways; define the role of these pathways in osteoporosis drug discovery; focus light on the link between bone, muscle, pancreas, and adipose integrative physiology and osteoporosis; and underline the emerging role of osteogenic exercise in the prevention of, and care for, osteoporosis, obesity, and diabetes.

Abstract
INTRODUCTION Antiepileptic drugs (AEDs) have been associated with a negative impact on bone health. Comorbid disorders in patients with epilepsy may require drugs exerting a pro-osteoporotic effect, so a possibility of untoward interactions with AEDs is probable. AREAS COVERED This review discusses evidence related to the deteriorating influence of AEDs on bone, demonstrating generally stronger negative effects of conventional AEDs. Lamotrigine seems to be a safer AED in this regard. Further, literature data indicate that generally AEDs can lower the serum concentration of vitamin D. Importantly, pediatric patients are of greater risk of bone problems during therapy with AEDs, which is probably due to their effects on bone-forming processes. EXPERT OPINION Supplementation with vitamin D and calcium is frequently recommended in patients taking AEDs chronically. Whether to add a bisphosphonate remains an open question due to the limited data on this issue. A possibility of negative interactions exists between AEDs and other pro-osteoporotic drugs: glucocorticoids, proton pump inhibitors and aromatase inhibitors. Depression is a frequent comorbidity in patients with epilepsy. Clinical data indicate that antidepressant drugs may also increase the risk of fractures. Again, patients with epilepsy and depression may be exposed to a greater risk of osteoporosis.

Abstract
Postictal syndrome (PIS) encompasses the clinical, biological, electroencephalographic (EEG) and magnetic resonance imaging (MRI) signs that follow the termination of a seizure. These signs occur as soon as the epileptic discharge ends, but might remain for a substantially long period of time, making them amenable to clinical observation. As a direct consequence, neurologists and intensivists are more frequently attending patients with PIS than during their seizure. Moreover, careful PIS documentation may help physicians to diagnose epileptic seizure from other non-epileptic disorders. Careful analysis of PIS could also be helpful to better characterize the seizure (seizure subtypes, and to some extent, the localization and/or lateralization of the seizure). This article aims to review the main clinical, biological, EEG and MRI components of PIS, discuss differential diagnoses and propose a general clinical attitude, based on the acronym "WAITTT": W for "Watch", to monitor and investigate PIS in order to provide relevant information on seizure, AIT for "Avoid Inappropriate Treatment", to underscore the risk carrying out unnecessary drug injections and intensive care procedures in the setting of a self-limited symptomatology, and TT for "Take Time", to keep in mind that time remains the clinician's best ally for treating patients with PIS.

[PMID: 31064117 PMCID: PMC6566727 DOI: 10.3390/nu11051016] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Revised: 04/28/2019] [Accepted: 05/03/2019] [Indexed: 12/13/2022] Open
Abstract
Hypovitaminosis D is becoming a notable health problem worldwide. A consensus exists among several different medical societies as to the need for adequate levels of vitamin D for bone and general health. The correct method by which to restore normal vitamin D levels is still a matter of debate. Although cholecalciferol remains the most commonly distributed form of vitamin D supplementation worldwide, several drugs with vitamin D activity are available for clinical use, and making the correct selection for the individual patient may be challenging. In this narrative review, we aim to contribute to the current knowledge base on the possible and appropriate use of calcifediol-the 25-alpha-hydroxylated metabolite-in relation to its chemical characteristics, its biological properties, and its pathophysiological aspects. Furthermore, we examine the trials that have aimed to evaluate the effect of calcifediol on the restoration of normal vitamin D levels. Calcifediol is more soluble than cholecalciferol in organic solvents, due to its high polarity. Good intestinal absorption and high affinity for the vitamin-D-binding protein positively affect the bioavailability of calcifediol compared with cholecalciferol. In particular, orally administered calcifediol shows a much shorter half-life than oral cholecalciferol. Most findings suggest that oral calcifediol is about three- to five-fold more powerful than oral cholecalciferol, and that it has a higher rate of intestinal absorption. Accordingly, calcifediol can be particularly useful in treating diseases associated with decreased intestinal absorption, as well as obesity (given its lower trapping in the adipose tissue) and potentially neurological diseases treated with drugs that interfere with the hepatic cytochrome P-450 enzyme system, resulting in decreased synthesis of calcifediol. Up to now, there has not been enough clinical evidence for its use in the context of osteoporosis treatment.

Abstract
INTRODUCTION Epilepsy is a serious chronic neurological disorder manifested by an enduring symptomatic predisposition to seizures. Newly diagnosed individuals face increased morbidity, mortality, and socioeconomic costs. Anti-epileptic drug therapy is the treatment usually prescribed, which has efficacy in seizure control and mitigating long-term mortality. AREAS COVERED Safety of anti-epileptic drug therapy in adults with a focus in newly diagnosed patients. Areas covered include the most commonly experienced adverse drug effects, as well as those with the highest impacts on drug tolerability, quality of life, morbidity and mortality. Evidence was also reviewed to identify clinical strategies to improve the safety of anti-epileptic drug therapy. EXPERT OPINION Anti-epileptic drugs (AEDs) are mostly effective and well tolerated. However, a lack of standardised reporting of adverse drug effects in trials and in clinical practice provides an obstacle for evaluation of which adverse drug effects need to be prioritised in management. Improvement in the reporting of cognitive and other effects, as well as improved precision medicine and pharmacogenomics to target the incidence of high-mortality idiosyncratic reactions, will help to reduce the harm of AEDs in people newly diagnosed with epilepsy.

Abstract
INTRODUCTION Vitamin D deficiency is common, world-wide, but vitamin D repletion throughout life, and into older age, has accepted health benefits for bone. Many mechanisms through which vitamin D also benefits soft tissues are understood, and clinical evidence of such benefits is now accumulating, especially following re-analyses of trial data, which are revealing previously missed health benefits with correction of deficiency. AREAS COVERED The sources of vitamin D, its activation, mechanistic effects; problems of trials of supplementation for reducing health risks, the benefits shown for mortality, cardiovascular disease, infection and cancer; the global problem of vitamin D deficiency; age-related reductions in vitamin D efficacy, and currently recommended intakes. EXPERT COMMENTARY High prevalence of vitamin D deficiency and insufficiency worldwide have proven ill-effects on health. Governmental efforts to improve population repletion by recommending minimal daily intakes does benefit some but is not effective at the population-level. However, food fortification with vitamin D3, already implemented in some countries, can solve this highly avoidable problem cost-effectively and is probably the best way to abolish vitamin D inadequacy, allowing public health benefits to emerge over time, thereby allowing future research on vitamin D to be directed at emerging issues on vitamin D.

Abstract
PURPOSE OF REVIEW Psychotropics are prescribed to youth at rapidly growing rates and may negatively impact bone health. Little awareness exists of this association among prescribing providers. Childhood and adolescence are critical times for bone development. Understanding these effects and their management is important to informed psychotropic use. RECENT FINDINGS Through a variety of mechanisms, antidepressants, benzodiazepines, mood stabilizers, neuroleptics, and stimulants may all negatively impact pediatric bone health. This confers added risk of osteoporosis in a population already at high risk for suboptimal bone health. Awareness of psychotropic-mediated effects on pediatric bone development is clinically relevant to the use and monitoring of these agents. Clinicians can manage these effects through informed consent, vitamin D supplementation, lifestyle modifications, and reducing polypharmacy. For mood stabilizers, vitamin D level monitoring and secondary prevention is indicated. Future longitudinal studies and development of monitoring guidelines regarding psychotropic impact on bone health are necessary.

Abstract
PURPOSE OF REVIEW The purpose is to provide a brief overview of factors that impact adolescent bone health and review special populations that deserve extra consideration of their bone health status. RECENT FINDINGS Optimization of modifiable factors is critical for adolescents to reach peak bone mass. Binge drinking, tobacco use, and certain medications all have accumulating evidence showing detrimental impacts on adolescent bone health and certain populations are more at risk for poorer bone health outcomes because of the nature of their conditions. Furthermore, very recent evidence suggests that in certain patients who have a history of insufficient nutritional and hormone status, 'catch-up' bone acquisition may not occur, underscoring the importance of early attention to these modifiable factors. SUMMARY Providers caring for adolescents should be aware of the many different populations at risk for poor bone health. Treatment that might further compromise bone health should be considered judiciously and providers should encourage optimization of any modifiable factor when possible.

Abstract
INTRODUCTION Carbamazepine (CBZ) is used for the treatment of epilepsy and other neurological and psychiatric disorders. The occurrence of adverse reactions (ADRs) to CBZ can negatively impact the quality of life of patients, as well as increase health-care costs. Thus, knowledge of CBZ-induced ADRs is important to achieve safer treatment outcomes. Areas covered: This review describes the clinical features, known mechanisms, and clinical management of the main CBZ-induced ADRs. In addition, pharmacogenetic studies focused on ADRs induced by CBZ are cited. Expert commentary: CBZ-induced ADRs are well known in the literature. The metabolite CBZ-10,11-epoxide plays an important role in the mechanism that underlies the ADRs induced by CBZ. Several factors should be considered for a safer use of CBZ, such as monotherapy prescription when possible, an adequate dose titration, knowledge of previous ADRs in the patient, and routine monitoring of CBZ plasma concentrations in symptomatic patients. Pharmacogenetics is a potential tool for CBZ therapy improvement, and the design of multicenter studies focused on the identification of biomarkers for CBZ-induced ADRs could provide useful information for a safer CBZ therapy.

Abstract
The severe sole effects of seizures on the cortical part of bone were reported in our previous study. However, the side effects of anti-epileptic drug therapy on bones has not been differentiated from the effects of the convulsive seizures, yet. This study provides the first report on differentiation of the effects of seizures and carbamazepine (a widely used antiepileptic drug) therapy on bones; 50 mg/kg/day drug was given to genetically induced absence epileptic rats for five weeks. Distinct bone regions including cortical, trabecular, and growth plate in each of tibia, femur, and spine tissues were studied using Fourier transform infrared (FT-IR) imaging and Vickers microhardness test. Blood levels of vitamin D and bone turnover biomarkers were also measured. According to the FT-IR imaging results, both seizure and carbamazepine-treated groups, more dominantly the drug-treated group, had lower mineral content with altered collagen crosslinks and higher crystallinity, implying reduced bone strength. Lower microhardness values also supported lower mechanical strength in bones. The most affected bone tissue and region from seizures and treatment was found as the spine and cortical, respectively. While there was a reduction in vitamin D and calcium levels in both seizure and carbamazepin-treated groups, significantly elevated PTH and bone turnover biomarkers were only seen in the drug-treated group.

Abstract
Malnutrition in elderly patients is a common condition. Nevertheless, there is evidence on specific risk factors and problems of malnutrition in geriatric patients with neurological diseases. In this review, we summarize recent knowledge on malnutrition in different neurological diseases with a focus on elderly patients. This overview also provides strategies for a more specific and profound assessment of neurogeriatric patients to improve identification and treatment of malnutrition. Early and consequent treatment of malnutrition can lead to a decreased progression of the neurological disease and to a better quality of life in geriatric patients.

Abstract
INTRODUCTION Vitamin D deficiency is an important public health problem worldwide. Vitamin D deficiency confers a significant risk for both skeletal and non-skeletal disorders and a number of lifelong negative health outcomes. The objectives of this evidence-based guidelines document are to provide health care professionals in Poland, an updated recommendation for the prevention, diagnosis and treatment of vitamin D deficiency. METHODS A systematic literature search examining the prevention and treatment strategies for vitamin D deficiency was conducted. Updated recommendations were developed using the Grading of Recommendations, Assessment, Development and Evaluation system describing the strength of the recommendation and the quality of supporting evidence. Twenty-seven contributors representing different areas of expertise and medical specialties, including pediatricians, geriatricians, endocrinologists, epidemiologists, nephrologists, gynecologists and obstetricians evaluated the available published evidence related to vitamin D, formulated the goals of this document and developed a common consolidated position. The consensus group, representing six national specialist consultants and eight Polish and international scientific organizations/societies, participated in the process of grading evidence and drawing up the general and specific recommendations. RESULTS The updated recommendations define the diagnostic criteria for the evaluation of vitamin D status and describe the prevention and treatment strategies of vitamin D deficiency in the general population and in groups at increased risk of the deficiency. Age- and weight-specific recommendations for prevention, supplementation and treatment of vitamin D deficiency are presented, and detailed practice guidance is discussed regarding the management in primary and specialized health care. CONCLUSION Vitamin D deficiency remains still highly prevalent in Poland, in all age groups. Currently, there is a great necessity to implement a regular supplementation with recommended doses and to develop an effective strategy to alleviate vitamin D deficiency in the population. These updated recommendations are addressed to health professionals and the authorities pursuing comprehensive health policies and should also be included in public health programs aimed at preventing a broad spectrum of chronic diseases.

Abstract
PURPOSE OF REVIEW It is well-recognized that individuals with epilepsy have an increased risk of vertebral and nonvertebral fractures; this increased risk has been described to be secondary to an increased bone fragility and to an increased risk of falls. Osteoporosis is the most common bone disease which has been characterized by microarchitectural deterioration of trabecula and cortical bone mass with a decrease in bone mineral density and bone strength. Specific side effects of antiepileptic drugs (AEDs) on bone metabolism have been identified; recent research publications further characterized some of the specific side effects of AEDs on bone metabolism. It is the purpose of this review to describe recent advances on the knowledge of the effects of AEDs on bone metabolism and the cause of osteoporosis in the field of epilepsy. RECENT FINDINGS Recent literature demonstrates that the increased risk of fractures in the epileptic patient population is likely multifactorial and includes seizure activity, injuries from falls, decreased bone strength, adverse effects from AEDs. Reviewed publications suggest that the mechanism of adverse effects on bone metabolism may differ among different AEDs. The impact of vitamin D deficiency or its metabolism in the epileptic population has also been a concern of several reviewed publications. SUMMARY This is a review is of the recent epilepsy and osteoporosis literature published over the past 18 months, highlighting reports and studies concerning the cause, pathogenesis, and possible preventive measures and effects of AEDs on changes of bone metabolism, bone loss, and development of osteoporosis. In addition, we also reviewed articles focusing on issues of prevention and treatment of osteoporosis in individuals with epilepsy. We utilized the search engines of PubMed and Cochrane Reviews from January 2016 to June 2017.
