Pregnancy associated Osteoporosis: Pathophysiology and management

Zillikens Carola

Although the baby growing in its mother’s womb needs calcium for skeletal development osteoporosis and fractures very rarely occur during pregnancy. Pregnancy- and lactation-associated osteoporosis with the occurrence of fragility fractures mainly of the vertebral bodies was first described as a syndrome Nordin et al. in 1955. It is most commonly observed in the third trimester or early post-partum in women presenting with severe and prolonged back pain and somet...

Background: The relation between sex hormone-binding globulin (SHBG) and vertebral fracture (VFx) is unclear.Aim: To examine whether SHBG is associated with bone mineral density at lumbar spine (LS-BMD), trabecular bone score (TBS) and prevalent VFx.Methods: Data of 6224 men and women participants in the third visit of the first cohort (I-3) and the first visit of the second cohort (II-1) of a prospective population based cohort, w...

The association between diabetes, trabecular bone score, bone mineral density and vertebral fractures

Koromani Fjorda , Muka Taulant , Oei Ling , Zillikens Carola , Hofman Albert , Franco Oscar H , Uitterlinden Andre G , Oei Edwin , Hans Didier , Rivadeneira Fernando

Background: Fracture risk is increased in Type 2 diabetes (T2D) individuals. Bone mineral density (BMD) is inversely associated with fracture risk but paradoxically high in T2D individuals. Trabecular bone score (TBS) reflects bone microarchitecture and predicts fracture risk.Objective: We aimed to compare mean lumbar spine TBS (LS-TBS) and lumbar spine BMD (LS-BMD) values, across individuals with and without i) vertebral fracture (VFx), ii) T2D; and iii...

Phenotypic dissection of bone mineral density facilitates the identification of skeletal site specificity on the genetic regulation of bone

Kemp John P , Medina-Gomez Carolina , Estrada Karol , Heppe Denise , Zillikens Carola , Timpson Nicholas , Pourcain Beate , Ring Susan , Hofman Albert , Jaddoe Vincent V W , Smith George Davey , Uitterlinden Andre G , Tobias Jonathan H , Rivadeneira Fernando , Evans David M

Heritability of bone mineral density (BMD) varies at skeletal sites, possibly reflecting different relative contributions of environmental and genetic influences. To quantify shared genetic influences across different sites, we estimated the genetic correlation of BMD at the upper limb (UL), lower limb (LL), and skull (S) obtained from whole body DXA scans, using bivariate genome-wide complex trait analysis (GCTA). The study (n=9395) combined data from the Avon Longit...

Bivariate analyses of BMD and lean mass in children identifies variants with novel pleiotropic effects across six BMD loci and in the TOM1L2 locus

Medina-Gomez Carolina , Kemp John P , Heppe Denise H M , Tobias Jon H , Hofman Albert , Carola Zillikens M , Uitterlinden Andre G , Jaddoe Vincent W V , Evans David M , Rivadeneira Fernando

Background: Lean and bone mass are heritable traits with high phenotypic correlation (rho=0.44), likely reflecting the underlying mechanical and biochemical interactions between tissues.Aim: Estimate the shared heritability (genetic correlation) of both traits in children and identify genetic determinants displaying pleiotropic effects on lean mass and bone mass accrual.Methods: Participants make part of two prospective po...
