OBJECTIVES: Throughout history, gout has been referred to as the "disease of the kings", and has been clearly associated with the lifestyle of the aristocratic social classes. According to the written sources, several members of the famous Medici family of Florence suffered from an arthritic disease that contemporary physicians called "gout". A paleopathological study carried out on the skeletal remains of some members of the family, exhumed from their tombs in the Church of San Lorenzo in Florence, offered a unique opportunity to directly investigate the evidence of the arthritic diseases affecting this elite group...

Though present in small amounts, the minor constituents of dietary oils may supplement the dietary therapies for rheumatoid arthritis (RA). Hence, in the present study, we assessed the effect of minor constituents from sesame oil (SO) and rice bran oil (RBO) and their fatty acids on the severity of adjuvant-induced arthritis in experimental rats. Rats were gavaged with 1 mL of SO or RBO or groundnut oil (GNO, control) with or without its minor components for a period 15 days before and 15 days after the induction of arthritis...

Collagen type Ⅱ (col Ⅱ) and aggrecan, the main components of the extracellular matrix (ECM) in human joint cartilage, have been reported to be reduced by chronic production of inflammatory cytokine interleukin (IL)-1β in arthritic joints. Carvedilol, a licensed medicine, has been used for treatment of hypertension, congestive heart failure and coronary disease in clinics. In this study, we investigated the effects of Carvedilol on the expression of col Ⅱ and aggrecan. Our results demonstrate that treatment with Carvedilol didn't change the expression of aggrecan or col Ⅱ at mRNA levels in SW1353 chondrocytes...

OBJECTIVE: Therapeutic agents that are transformable via introducing cleavable linkage by locally enriched MMP-2 within inflamed synovium would enhance therapeutic efficacy on chronic inflammatory arthritis. Transforming growth factor-β-inducible gene-h3 (βig-h3), which consists of four fas-1 domains and an Arg-Gly-Asp (RGD) motif, intensifies inflammatory processes by facilitating adhesion and migration of fibroblast-like synoviocyte in the pathogenesis of rheumatoid arthritis (RA)...

OBJECTIVE: Cytosolic DNA sensors detect microbial DNA and promote type I interferon and pro-inflammatory cytokine production through the adaptor stimulator of interferon genes (STING) to resolve infection. Endogenous DNA also engages the STING pathway, contributing to autoimmune disease. We identified a novel role for STING in bone in arthritic DNase II/IFNaR double deficient (DKO) mice, and sought to define the bone phenotype in these mice and to address mechanism. METHODS: Bone parameters were evaluated in DKO, STING/DNaseII/IFNaR triple deficient and control mice by microcomputed tomography and histomorphometry...

Rheumatoid arthritis, a synthesized form of adjuvant arthritis exhibited throughout many animal species, inhibits liver function and circulation of IGF-I and contributes to the degradation of skeletal muscle mass. One of the primary goals of the present study is determining whether a high-Methionine (high-Met) diet is capable of reducing the adverse effects of arthritis, namely, loss of body mass. Following adjuvant injection, forty arthritic rats were randomly assigned to either a control group with a basal diet or a high-Met group with the same basal diet + 0...

In rheumatoid arthritis (RA), synovial fibroblasts (RA-SFs) accumulate in affected joints, where they play roles in inflammation and joint destruction. RA-SFs exhibit tumor-like proliferation and are resistant to apoptosis. Although RA-SF activation is well described, negative regulators of RA-SF activation are unknown. We previously reported that histone deacetylase (HDAC) inhibitors facilitate apoptosis in RA-SFs. Here we found that RA-SFs treated with the HDAC inhibitor Trichostatin A (TSA) exhibited an upregulation of the immediate early response gene X-1 (IEX-1)...

Rheumatoid arthritis is a chronic inflammatory joint disorder characterised by erosive inflammation of the articular cartilage and by destruction of the synovial joints. It is regulated by both genetic and environmental factors, and, currently, there is no preventative treatment or cure for this disease. Genome-wide association studies have identified ∼100 new loci associated with rheumatoid arthritis, in addition to the already known locus within the major histocompatibility complex II region. However, together, these loci account for only a modest fraction of the genetic variance associated with this disease and very little is known about the pathogenic roles of most of the risk loci identified...

BACKGROUND: Scaphoid fractures represent the most common carpal fractures and are often problematic and frequently lead to nonunion with osteoarthritis and collapse of the wrist. The reasons for the nonunion are manifold. Therefore, the main goal of diagnosis and therapy of acute fractures is to achieve bony union and to restore the anatomic shape of the scaphoid. In the long run, only this can preserve the normal function of the wrist. METHODOLOGY: The given recommendations are based on the new S3-level guideline of the AWMF (Association of the Scientific Medical Societies)...

OBJECTIVE: Osteoarthritis (OA) is a heterogeneous, multi-tissue disease. We hypothesised that different histopathological features characterise different stages during knee OA progression, and that discrete subgroups can be defined based on validated measures of OA histopathological features. DESIGN: Medial tibial plateaux and synovium were from 343 post-mortem (PM) and 143 OA arthroplasty donations. A `chondropathy/osteophyte' group (n=217) was classified as PM cases with osteophytes or macroscopic medial tibiofemoral chondropathy lesions ≥ grade 3 to represent pre-surgical (early) OA...

We set out to investigate the influence of STA-21, a dynamic STAT-3 inhibitor, on the expansion and progression of rheumatoid arthritis (RA), and to determine its potential mechanisms of action in a mouse model of collagen antibody-induced arthritis (CAIA). To this end, arthritis was induced via intravenous (IV) injection of Balb/c mice with a cocktail of antibodies directed against type II collagen (1.5μg/mouse, IV), followed by lipopolysaccharide (LPS) at a dose of (25μg/mouse, i.p.) on day 3. Mice were then left untreated or were simultaneously treated with STA-21 (0...

Two basic discoveries spurred research into inflammation as a driving force in the pathogenesis of Alzheimer's disease (AD). The first was the identification of activated microglia in association with the lesions. The second was the discovery that rheumatoid arthritics, who regularly consume anti-inflammatory agents, were relatively spared from the disease. These findings led to an exploration of the inflammatory pathways that were involved in AD pathogenesis. A pivotal advance was the discovery that amyloid-β protein (Aβ) activated the complement system...

PURPOSE: The aim of this study was to assess the kinematics of arthritic knees prior to TKA. The hypothesis was that the arthritic knee follows distinct patterns with regard to deformity in coronal plane as it flexes from extended position. METHOD: Data from 585 consecutive arthritic knees that had undergone TKA using two non-image-based navigation systems were included in the study. Coronal plane alignment given by the femoro-tibial mechanical angle (FTMA) was recorded in extension, 30°, 60°, 90° and maximum flexion prior to making any bony cuts or ligamentous releases...

Peptide-based therapy, such as modified peptides, has attracted increased attention. IL-17 is a promising therapeutic target for autoimmune diseases, and levels of circulating bioactive IL-17 are associated with rheumatoid arthritis severity. In this study, a modified truncated IL-17RC is generated to ameliorate inflammation and bone destruction in arthritis. The truncated IL-17RC binds to both IL-17A and IL-17F with higher binding capacity compared to nonmodified IL-17RC. In addition, the truncated IL-17RC reduces the secretion of inflammatory and osteoclastogenic factors induced by IL-17A/F in vitro...

Considering the functions of aggrecanase-1 (ADAMTS4) and -2 (ADAMTS5), which are thought to be the two major enzymes responsible for the destruction of aggrecans in arthritic diseases, we investigated whether important polymorphisms in the ADAMTS4 and ADAMTS5 genes affect osteoarthritis (OA) susceptibility. Our study took place in Mugla, Turkey. Ninety-five cases were recruited following OA diagnosis (72 women and 23 men), and 80 individuals without any symptoms or radiographic signs of OA (56 women and 24 men) were chosen as healthy controls...
