Is IgG galactosylation the relevant factor for pregnancy-induced remission of rheumatoid arthritis?

During pregnancy, most patients with rheumatoid arthritis (RA) experience spontaneous improvement of their disease activity. Among the soluble candidates that have been investigated in search for the most relevant disease-remitting factor are the galactosylation levels of immunoglobulin G (IgG). In RA, a higher percentage of IgG lacking the terminal galactose residues, thought to play a pro-inflammatory role, is found. During pregnancy, however, IgG galactosylation levels increase and correlate with improved disease activity. The question remains whether the increase in IgG galactosylation during pregnancy is a mere epiphenomenon or a true remission-inducing factor.

Effectiveness of individual resource-oriented joint protection education in people with rheumatoid arthritis. A randomized controlled trial

the modern joint protection (JP) concept for people with rheumatoid arthritis (RA) is an active coping strategy to improve daily tasks and role performance by changing working methods and using assistive devices. Effective group JP education includes psycho-educational interventions. The Pictorial Representation of Illness and Self Measure (PRISM) is an interactive hands-on-tool, assessing (a) the individual's perceived burden of illness and (b) relevant individual resources. Both issues are important for intrinsic motivation to take action and change behaviour. This study compared individual conventional JP education (C-JP) with PRISM-based JP education (PRISM-JP).

Influence of anti-infliximab antibodies and residual infliximab concentrations on the occurrence of acquired drug resistance to infliximab in rheumatoid arthritis patients

Infliximab (IFX) can be immunogenic for humans and lead to the formation of antibodies against IFX (anti-IFX Ab), which could induce acquired IFX resistance.

[Ultrasound and arthritis]

Musculoskeletal ultrasonography (US) is an established and validated imaging technique in rheumatology. Ultrasonography is able to directly visualize soft tissue pathologies such as synovial tissue changes. Pathological findings in superficial cartilage, bone lesions and synovial tissue changes in the context of rheumatoid arthritis, spondyloarthritis or crystal arthropathies may only be seen by sonography or detected earlier by ultrasonography compared to conventional imaging techniques. The activity of an inflammatory arthropathy can be visualized using Doppler and power Doppler US. US is helpful in the detection of early inflammatory changes, particularly in patients with undifferentiated arthritis and/or unremarkable conventional radiography. In addition to diagnosis in early arthritis and monitoring of therapy in rheumatoid arthritis, sonography is able to detect pivotal pathologies in spondyloarthritis and crystal deposition diseases such as gout, pseudogout and apatite deposition disease. Ultrasound-guided diagnostic and therapeutic interventions are characterized by their excellent accuracy and improvement of clinical effectiveness compared to unguided procedures. In conclusion, ultrasonography plays a pivotal role in the assessment and monitoring of therapy in rheumatic diseases.

Six and 12 months' effects of individual joint protection education in people with rheumatoid arthritis: A randomized controlled trial

Joint protection (JP) education for people with rheumatoid arthritis (RA) is effective when applying psycho-educational teaching strategies. The Pictorial Representation of Illness and Self Measure (PRISM) was used to identify relevant JP education goals and life aspects, both supporting motivation and behaviour change. The objective of this study was to compare the effects of individual JP education, PRISM-based (PRISM-JP) vs. conventional (C-JP), in people with rheumatoid arthritis (RA).

Biologics in rheumatoid arthritis--recommendations for Swiss practice

The new paradigm of therapy in rheumatoid arthritis is to aim toward early and complete remission, using a larger use of conventional DMARDs and biologic agents. The present recommendations were established through a consensus to help practitioners in their daily use of those agents, to reflect the current "best practice" in Switzerland.

Elevated laser flare values correlate with complicated course of anterior uveitis in patients with juvenile idiopathic arthritis

To evaluate the prognostic value of anterior chamber (AC) laser flare (LF) in uveitis associated with juvenile idiopathic arthritis (JIA).

Influence of pregnancy on the adipocytokine and peroxisome proliferator-activated receptor pathways in peripheral blood mononuclear cells from healthy donors and rheumatoid arthritis patients

To identify candidate genes that are regulated by human pregnancy and have the potential to modulate rheumatoid arthritis (RA) disease activity.

The postoperative COFAS end-stage ankle arthritis classification system: interobserver and intraobserver reliability

End-stage ankle arthritis is operatively treated with numerous designs of total ankle replacement and different techniques for ankle fusion. For superior comparison of these procedures, outcome research requires a classification system to stratify patients appropriately. A postoperative 4-type classification system was designed by 6 fellowship-trained foot and ankle surgeons. Four surgeons reviewed blinded patient profiles and radiographs on 2 occasions to determine the interobserver and intraobserver reliability of the classification. Excellent interobserver reliability (κ = .89) and intraobserver reproducibility (κ = .87) were demonstrated for the postoperative classification system. In conclusion, the postoperative Canadian Orthopaedic Foot and Ankle Society (COFAS) end-stage ankle arthritis classification system appears to be a valid tool to evaluate the outcome of patients operated for end-stage ankle arthritis.

Slow release antibiotics for treatment of septic arthritis in large animals

The search for an effective treatment for septic arthritis is ongoing. Current therapies are expensive since they require repeated joint lavage and long term antibiotic treatment. Local application of antimicrobial drugs is advantageous because high concentrations can be attained at the infection site, although repeated injections increase the risk of superinfection of the joint. Thus, slow release formulations, which have the advantage of local treatment yet single application of the drug, are appealing. Antibiotics used in slow release formulations are selected for tissue compatibility, an appropriate antibacterial spectrum, and stability both during the mixing procedure and within the carrier during the release period. Ideally the carriers should be bioresorbable. Promising reports on the clinical use of poly(methyl methacrylate) (PMMA) mixed with several different antibiotics, and of collagen sponges impregnated with gentamicin, should encourage the search for formulations optimally adapted to veterinary medical requirements.
