Mutual associations among diseases causing disability, such as musculoskeletal diseases, metabolic syndrome components, and mild cognitive impairment: a 3-year follow-up of the ROAD study

Yoshimura Noriko , Muraki Shigeyuki , Oka Hiroyuki , Tanaka Sakae , Kawaguchi Hiroshi , Nakamura Kozo , Akune Toru

To assess the associations among diseases causing disability requiring support, including i) musculoskeletal diseases (knee osteoarthritis (KOA), lumbar spondylosis (LS), and osteoporosis (OP)); ii) metabolic risk factors for cardiovascular diseases, including overweight (OW), hypertension (HT), dyslipidaemia (DL), and impaired glucose tolerance (IGT); and iii) mild cognitive impairment (MCI).Among 1690 participants (596 men and 1094 women) at the baseli...

Bone marrow lesions are characterized by increased bone turnover and increased vascularity

Shabestari Maziar , Vik Jarle , Reseland Janne , Eriksen Erik Fink

Bone marrow lesions (BMLs), previously denoted bone marrow edema are detected as water signals on MR scans (low intensity on T1 weighted images and high intensity on T2 weighted scans). Previous histologic studies were unable to demonstrate any edematous changes at the tissue level, which led us to hypothesize that the water signal stems from increased vascularization accompanying a high turnover state in bone. To test this hypothesis we performed tetracy...

Phenotypic and functional characterization of osteoclast progenitors in circulatory and synovial compartments of patients with rheumatoid arthritis

Sucur Alana , Jajic Zrinka , Ikic Marina , Ivcevic Sanja , Kelava Tomislav , Grcevic Danka

Rheumatoid arthritis (RA) is marked by the persistent inflammation and osteodestruction, causing progressive disability. Osteoclast progenitors (OCPs) represent a subpopulation of peripheral blood monocytes and have been shown to be present in healthy subjects and arthritic patients. The aim of our study was to determine the phenotype, frequency and osteoclastogenic potential of OCPs in the peripheral blood and synovial fluid of RA patients in response to anti-TNF therapy....

MIV-711, a highly selective cathepsin K inhibitor: safety, pharmacokinetics and pharmacodynamics of multiple oral doses in healthy postmenopausal women

Grabowska Urszula , Lindstrom Erik , Jerling Markus , Edenius Charlotte

Introduction: Cathepsin K is necessary for bone matrix resorption. Excessive resorption associated with osteoporosis and osteoarthritis can be reduced by cathepsin K inhibition. MIV-711, a highly selective cathepsin K inhibitor, successfully attenuates both bone resorption and cartilage degradation in non-clinical studies.Aim: To determine safety, tolerability, pharmacokinetics and pharmacodynamics of MIV-711 during multiple oral dosing to postmenopausal...

Do osteophytes protect femoral neck against fracture in osteoarthritis?

Rabelo Gustavo Davi , Roux Jean Paul , Portero-Muzy Nathalie , Boutroy Stephanie , Chapurlat Roland , Chavassieux Pascale

Beside the bone mass, structural changes are important determinants of the bone strength. Patients with osteoarthritis (OA) seem protected against femoral neck (FN) fracture. When compared to osteoporosis, FN in OA are characterized by a higher bone mass and a better trabecular microarchitecture (Blain et al., 2008, Boutroy et al., 2011). The presence of microcracks is one of the determinants of the bone strength. The aim of this study was to evaluate the mic...

Comparison of trabecular bone composition between osteoarthritis and non-osteoarthritis of distal femur by Raman spectroscopy

Kim Kwangkyoun

Objectives: The purpose of this study is to determine the chemical information in trabecular bone by Raman spectroscopy in the osteoarthritic and non-osteoarthritic distal femur.Materials and methods: Distal femur specimens were obtained from ten donors composed of ten womens with OA (mean age of 63 years, ranging from 50 to 76). As controls, the normal distal femur was sampled from age and gender matched donors consisting of ten womens (mean age of 53 y...

The influence of the 24-month treatment with anti-CD20 antibodies (rituximab) on bone mineral density in patients with rheumatoid arthritis

Dydykina Polina , Dydykina Irina , Devyataikina Anna , Lukina Galina , Smirnov Alexandr , Nasonov Evgeniy

Background: The activity of rheumatoid arthritis (RA) is the one of the significant reasons of the increase of bone resorption and decrease of bone mineral density (BMD). The control of activity of inflammatory process with biologics (including rituximab – anti-CD20 antibodies) can be considered as possibility of decrease in bone resorption and BMD stabilization.Objectives: To access the dynamics of BMD after 24 months of treatment with rituximab in...

Cartilage oligomeric matrix protein assay on the IDS-iSYS automated system

Lorenzo Pilar , Manolopoulou Jenny , Seres Zoltan

Diseases affecting the musculoskeletal system are a major cost burden to society. Articular cartilage loss or damage in these diseases is detected by radiography and measuring decreases in joint space width (JSW). The early stages of the disease may remain latent and asymptomatic for many years. This forms the rationale for applying molecular marker technology (biomarkers) to identify patients prone to joint diseases. One such biomarker is cartilage oligomeric matrix protein (...

RANK expression is reduced in circulating monocytes from ankylosing spondylitis patients

Perpetuo Ines Pedro , Caetano-Lopes Joana , Vieira-Sousa Elsa , Campanilho-Marques Raquel , Ponte Cristina , Canhao Helena , Ainola Mari , Fonseca Joao Eurico

Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are systemic, immune-mediated diseases. RA’s main targets are the peripheral joints while AS has the axial skeleton and enthesis as the principal affected areas. RA is characterized by bone erosions and impaired repair whilst AS is typified by bone overgrowth. The causes for these differences are not yet understood; however we hypothesize that AS patients’ monocytes receive reduced osteoclastogenic stimuli and...

Effect of risedronate on painful periprosthetic resorption of total hip arthroplasty: preliminary observational study

Behra-Marsac Aurelie , Bonnet Christine , Mabit Christian , Coste Cedric , Preux Pierre-Marie , Vergne-Salle Pascale , Dufauret-Lombard Carine , Treves Richard , Bertin Philippe

Total hip arthroplasty (THA) is the treatment for severe hip osteoarthritis. It improves the quality of life, pain and patient autonomy. However, a periprosthetic resorption may occur, in 3–5% of patients after 10 years of the primary surgery requiring implant replacement. Bisphosphonates (BP), inhibitors of bone resorption, represent a potential candidate for modulating periprosthetic bone loss. Randomized controlled trials have also suggested that BP could prevent early...

Bone secreted dickkopf-related protein 1 ameliorates osteoarthritis in mice

Funck-Brentano Thomas , Bouaziz Wafa , Marty Caroline , Geoffroy Valerie , Hay Eric , Cohen-Solal Martine

Objective: Cartilage loss and subchondral bone changes are hallmarks of osteoarthritis (OA). The Wnt family is involved in the regulation of bone and cartilage. We have shown that the Wnt/β-catenin pathway is activated in bone during OA, but the effect of its inhibition in bone in cartilage remodeling is unknown. We here investigated the impact of the bone-specific inhibition of Wnt during the development of OA.Methods: Partial meniscectomy (Mnx) wa...
