Generalized long term bone loss in early rheumatoid arthritis in the biologic treatment era: a 10-year prospective observational study

Proven Anne , Helgetveit Knut , Haugeberg Glenn

Background: Several short-term studies have been performed in rheumatoid arthritis (RA) reporting a rapid rate of generalized bone loss. Aggressive anti-inflammatory treatment with biologic disease modifying anti-rheumatic drugs (DMARDs) has been shown to reduce the rate of bone loss1. There is a lack of long term follow-up studies.Objectives: To study 10-year changes in generalized bone loss in early RA patients in the biologic treatment era....

Ultrasound carotid plaque morphology in rheumatoid arthritis women without previous cardiovascular events

Castro Alice , Carmona-Fernandes Diana , Santos Maria Jose , Mendes-Pedro Luis , Canhao Helena , Fonseca Joao Eurico

Introduction: In rheumatoid arthritis (RA) patients subclinical atherosclerosis and cardiovascular events (CV) occur more frequently and at younger ages than in the general population. Previous data suggest that heterogeneous plaques on USA are more unstable and frequently contain a higher amount of lipids and which make them hypoechoic and had higher potential for embolization and thrombosis. The aim of our work was to estimate the prevalence and the ultrasound morphology of ...

Bone mineral density changes after total knee replacement in women over the age of 65

Kim Deog Yoon

Objective: We analyze changes of spine BMD and hip BMD after total knee replacement (TKR) according to osteoporosis medication, bilaterality of operation site, degree of obesity, degree of knee function and osteoporosis diagnosis at operation in female patients above 65 years old, who received TKR due to severe knee osteoarthritis,Method: 52 patients who checked 1 year follow-up BMD were enrolled. Patients were checked the spine and hip BMD at pre-operat...

Rehabilitation of patients with early rheumatoid arthritis, including cryotherapy, physical exercises, occupational therapy, orthoses, and therapeutic education

Orlova Evgeniya , Karateev Dmitry , Kochetkov Andrey , Denisov Lev

Introduction: The evidence for the effectiveness of early rehabilitation of patients with rheumatoid arthritis (RA) is scanty. The aim of the study is to evaluate the efficiency of rehabilitation program for patients with early RA.Methods: 34 study group patients with early RA underwent 6-month rehabilitation (hospital stage: 15-min local air cryotherapy (−;60 °C, Criojet Air C600) for hand, knee or ankle joints, 45-min therapeutic exercises u...

The femoral neck fractures in patients with rheumatoid arthritis

Podvorotova Marina , Dydykina Irina

The femoral neck fractures (FNF) are one of the most common non-traumatic fractures in elderly people. Frequently the patients with fractures of this localization need surgical treatment and long-term rehabilitation. It’s widely known that FNF in patients with rheumatoid arthritis (RA) occur more often than in the population.Background: To determine the frequency of FNF in patients with RA and to characterize the patients with RA and with FNF at the...

Sclerostin/MEPE axis in OA: lessons from long bone development

Staines Katherine , Poulet Blandine , Farquharson Colin , Pitsillides Andrew

The re-initiation of developmental processes in osteoarthritis (OA) has emerged with similarities to endochondral ossification; responsible for long bone development. We aimed to establish the role of the Wnt inhibitor, sclerostin in endochondral ossification, and its relationship with MEPE, a calcification inhibitor with potential downstream functions. Knee joints from male Str/ort (spontaneous OA) and age-matched CBA control mice were analysed at 8, 18, and 40+ weeks of age ...

The glutamate receptor antagonist NBQX alleviates inflammation, pathology and gait abnormalities in rat antigen induced arthritis

Bonnet Cleo , Williams Anwen , Gilbert Sophie , Harvey Ann , Evans Bronwen , Mason Deborah

Objectives: Synovial fluid glutamate concentrations increase in various arthritides. Activation of kainate (KA) and AMPA glutamate receptors (GluRs) increase interleukin 6 (IL6) release and cause arthritic pain respectively. GluR antagonists represent potential peripheral treatments for inflammatory arthritis and inflammatory mechanisms that contribute to osteoarthritis (OA). We hypothesised that AMPA and KA GluRs are expressed in arthritic joint tissues and that peripheral ad...

A deletion mutation of the gene P58IPK, the cellular inhibitor of PKR and PERK, results in a degenerative joint phenotype in mice

Gilbert Sophie , Nowell Mari , Bonnet Cleo , Ladiges Warren , Morton John , Duance Vic , Mason Debbie

Objective: The protein kinases, PKR, and PERK have been implicated in pro-inflammatory cytokine-mediated cartilage degradation in vitro and endoplasmic reticulum stress-induced arthritis respectively. The objective of this study was to establish whether loss of P58IPK, an inhibitor of PKR and PERK, results in a degenerative joint phenotype in vivo.Methods: Sections of knee joints from P58IPK-null and wild-type mice...

Changes and comparison of bone metabolism, bone mineral density, MRI in early rheumatoid arthritis

Vershhynina Diana , Ryzhyk Varerij , Mikhalchenko Olena , Golovach Iryna , Dudij Peter , Semeniv Igor , Shevchuk Olga

The problem of early diagnosis of rheumatoid arthritis remains an important area of research in rheumatology. We investigated changes in bone metabolism, bone mineral density in early rheumatoid arthritis (ERA; up to 12 months). Data were compared with changes in the MRI study of the dominant hand.We observed 24 patients with ERA, the average age – 33.6±5.7 years. The men were 6 (25%), women – 18 (75%). Bone mineral density (BMD) was deter...

A GWAS in an extreme high bone mass population shows excess signal from genes associated with BMD in the normal population

Gregson Celia L , Leo Leo Paul J , Clark Graeme R , Smith George Davey , Brown Matthew A , Tobias Jon H , Duncan Duncan Emma L

Extreme high bone mass (HBM) may be monogenic (e.g. due to mutations in SOST or LRP5) or polygenic, due to variants in the same genes determining bone mineral density (BMD) as found in the general population. We aimed to determine the genetic cause underlying HBM in an extreme HBM population.258 unexplained HBM cases (defined as L1 Z-score ≥+3.2 plus total hip Z-score ≥+1.2, or total hip Z-score ≥+3.2 and L1 <...
