Epigenetic influences on childhood bone accrual

Javaid Kassim

Fragility fractures including hip fracture are a significant global burden. There is a growing body of evidence that the early environment influences an individual’s risk of fracture. Evidence from longitudinal studies have demonstrated the relationship between measures of body size in early life with later bone mass and risk of fragility fracture. These observations have been extended by parent/offspring cohorts with detailed examination of the maternal environment and s...

Epigenetic influences on childhood bone accrual

Javaid Kassim

Biographical DetailsAfter completing medical training at Charing Cross and Westminster Medical School, I specialized in adult rheumatology at the Wessex Deanery. During that time, I completed a PhD examining the maternal determinants of intra-uterine bone growth as part of an ARC Clinical Fellowship at the University of Southampton. In my last year of clinical training, I was fortunate to...

Characterization of pain in patients with fibrous dysplasia

Spencer Tiahna , Javaid Kassim , Boyce Alison

Pain is common in patients with fibrous dysplasia (FD), however the mechanisms and presentation of pain is poorly understood. Retrospective studies have shown that pain in FD presents along a broad spectrum, responds variably to treatment, and does not correlate with FD disease burden. Pain may be generally conceptualized into two categories: nociceptive pain (associated with actual or potentially tissue damaging stimuli) and neuropathic pain (caused by dysfunction of the soma...

Rare diseases of bones, joints and vessels study

Forestier-Zhang Lydia , Barrett Joe , Wordsworth Paul , Luqmani Raashid , Bishop Nicholas , Kassim Javaid Muhammad

Background: There are currently 456 rare bone disease recorded within 40 groups. Within many of these diagnoses there is marked heterogeneity of severity and complications that is often not explained by current understanding of disease mechanisms. There is an urgent need to improve the care of these patients by developing novel diagnostic tests and therapies based on understanding sub-phenotypes within existing diagnostic groups.Aim: To develop a nationa...

Two-fold regional variation in initiation of anti-osteoporosis medication after hip fracture in the UK

Shah Anjali , Prieto-Alhambra Daniel , Hawley Samuel , Delmestri Antonella , Lippett Janet , Cooper Cyrus , Judge Andrew , Javaid Kassim

Objective: Describe UK regional variation in prescription of anti-osteoporosis drug therapy before and after a primary hip fracture during 1999–2013.Materials and Methods: We used primary care data (Clinical Practice Research Datalink) to identify patients with a hip fracture and primary-care prescriptions of any anti-osteoporosis drugs (bisphosphonates, strontium, denosumab, oestrogen therapy, SERMS, teriparatide) prior to primary hip fracture and ...

Maternal vitamin D status has been positively associated with infant bone mass in observational studies. We therefore evaluated whether 1000 IU/day cholecalciferol during pregnancy would lead to greater offspring bone mass at birth, in a UK, multicentre, randomised, double-blind, placebo-controlled trial (MAVIDOS, ISRCTN82927713).At 12 weeks’ gestation, pregnant women with a serum 25-hydroxyvitamin D [25(OH)D] 25-100 nmol/l were randomised to either...

25-hydroxyvitamin D response to antenatal cholecalciferol supplementation is associated with common vitamin D related genetic variants: findings from the MAVIDOS trial

Objectives: Single nucleotide polymorphisms (SNP) in genes related to vitamin D metabolism have been associated with 25-hydroxyvitamin D (25(OH)D) status, but these relationships have not been examined in pregnancy or following antenatal vitamin D supplementation. We assessed whether SNPs in DHCR7 (7-dehydrocholesterol reductase), CYP2R1 (25-hydroxylase), CYP24A1 (24-hydroxylase) and GC (Vitamin D binding protein) were associated with the re...
