Introduction: Metabolic syndrome (MetS) is comprised of a clustering of various cardiovascular risk factors that can also affect bone health. We aimed the associations between MetS and bone mineral density (BMD) and trabecular bone score (TBS) in subjects with abdominal adiposity.Methods: Individuals with body mass index less than 25 kg/m2 were enrolled from the SUVINA study and allocated into two groups according criteria of IDF for metabolic syndrome. TBS T-score and Z/T score of fore skeletal region were measured using dual-energy X-ray absorptiometry (DXA). SPSS software was used for statistical analysis and p value 0<0.05 was considered significant.Results: DXA measurements were made in 201 participants, of whom 75 had MetS and 126 did not. Scores related to the neck of femur and total femur, radius Z-score and TBST-score were lower in subjects with MetS (all P<0.05). Subjects with FBG≥100 had lower TBST-score (p < 0.05). SBP≥130 and DBP≥85 in subjects, led to the lower TBST-score, and lumbar T-score (both P < 0.05). Subjects with (LDL-C≥160 mg/dl) had lower TBST-score, neck of femur Z score, and total femur T/Z scores (all P < 0.05). TBST-score and scores related to neck of femur, and total femur were lower in participants with serum cholesterol≥200 mg/dl (P < 0.05).Conclusion: MetS is negatively associated with TBS and BMD scores. Higher levels of LDL-C and cholesterol were the most associated factors related to TBST-score decrease. The neck of femur was the most vulnerable skeletal against the MetS components increment.

Metabolic syndrome and its various manifestations are considered to be a significant health epidemic in the developed and developing countries across the world. Metabolic syndrome is characterized by a series of metabolic abnormalities, such as central adiposity, insulin resistance, hypertension, glucose intolerance, and dyslipidemia. Patients with metabolic syndrome are at a higher risk of major complications, including fatty liver, type II diabetes mellitus, and cardiovascular diseases. Nuclear receptors are the key regulators of gene transcription, as well as several metabolic pathways. Among these receptors, LXRα and β play a major role in the regulation of lipogenesis, cholesterol/glucose homoeostasis, and inflammatory pathways through the induction or repression of target genes. In addition to metabolic homeostasis and diseases, lipogenesis and hypertriglyceridemia are regarded as the most significant adverse effects of liver X receptor (LXR) activation. Given the importance of lipid and carbohydrate metabolism and inflammation in the development of metabolic disorders, the present study aimed to review the impact of LXR signaling on the risk of metabolic syndrome and its phenotypes, with an emphasis on their potential therapeutic applications in the treatment of metabolic syndrome. In general, growing evidence supports the notion that LXRs may represent the potential drug targets for the treatment of metabolic syndrome.
