| Abstract | Patients with epilepsy and treated with antiepileptic drugs (AEDs) may develop metabolic bone disease, however, the exact pathogenesis of bone loss with AEDs is still unclear. Included were 75 adults with epilepsy (mean age: 31.90±5.62years; duration of treatment with AEDs: 10.57±3.55years) and 40 matched healthy controls. Bone mineral content (BMC) and densities (BMD) of the femoral neck and lumbar spine were measured using dual energy X-ray absorptiometry (DEXA). Blood samples were analyzed for calcium, magnesium, phosphate, alkaline phosphatase (ALP), 25-hydroxy vitamin D (25OHD), soluble receptor activator of nuclear factor kB ligand (sRANKL), osteoprotegerin (OPG) and OPG/RANKL ratio (markers of bone remodeling). Compared to controls, patients had lower BMD, BMC, Z-score and T-score at the femoral neck and lumbar spine (all p<0.001). 72% and 29.33% of patients had osteoporosis of the lumbar spine and femoral neck. Patients had significantly lower serum calcium, 25(OH)D and OPG and higher ALP, sRANKL levels and sRANKL/OPG (all p<0.001). 52% of patients had hypocalcemia, 93% had hypovitaminosis D, 31% had high levels of sRANKL and 49% had low levels of OPG. No differences were identified between DEXA and laboratory results in relation to the type, dose or serum levels of AEDs. BMD at the femoral neck and lumbar spine were found to be correlated with the duration of illness (p=0.043; p=0.010), duration of treatment with AEDs (p<0.001; p=0.012) and serum levels of 25(OH)D (p<0.042; p=0.010), sRANKLs (p=0.005; p=0.01) and OPG (p<0.006; p<0.01). In linear regression analysis and after adjusting for gender, age, weight, duration and number of AEDs, we observed an association between BMD, 25(OH)D (p=0.04) and sRANKL (p=0.03) concentrations. We conclude that AEDs may compromise bone health through disturbance of mineral metabolism and acceleration of bone turnover mechanisms. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
