Syndromes associated with concurrent skin and joint inflammation frequently pose a therapeutic challenge for both dermatologists and rheumatologists. In part 1 of this review, we discussed psoriatic arthritis as well as the autoinflammatory disorders SAPHO syndrome, Still's disease and Behçet's disease. Part 2 will address rheumatoid arthritis, reactive arthritis, Reiter's syndrome and Lyme borre...
This review aims to determine whether ultrasound-guided platelet-rich plasma injection has any role in improving clinical outcomes in patients with hip osteoarthritis. A search of the National Institute for Health and Care Excellence database using the Healthcare Databases Advanced Search tool was conducted. The PubMed database was also utilised to search the Medical Literature Analysis and Retri...
In recent years, low dose naltrexone (LDN) has been used as an off-label therapy for several chronic diseases. Results from small laboratory and clinical studies indicate some beneficial effects of LDN in autoimmune diseases, but clinical research on LDN in rheumatic disease is limited. Using a pharmacoepidemiological approach, we wanted to test the hypothesis that starting LDN leads to reduced di...
Esophageal carcinoma, with a increasing incidence, is one of the most aggressive carcinomas in gastrointestinal tract. Epidemiologic studies demonstrate an association of oral pathogens with multiple diseases, including rheumatoid arthritis, cardiovascular diseases, diabetes, and gastrointestinal malignancies. Nevertheless, a causal relationship between oral pathogens and esophageal squamous cell ...
The receptor activator of nuclear factor kappa-B ligand (RANKL) is an important factor for osteoclastogenesis and contributes to the pathology of rheumatoid arthritis (RA); thus, the anti-RANKL antibody (Ab) has been expected to protect joint destruction in RA patients. Interleukin (IL)-8 also has osteoclastogenic activity; however, the role of IL-8 in the bone pathology of RA as well as the relat...
Dysregulated signal transduction and activator of transcription-3 (STAT3) signalling in CD4+ T cells has been proposed as an early pathophysiological event in RA. We sought further evidence for this observation, and to determine its clinical relevance.
The diagnostic value added by musculoskeletal ultrasound (MSUS) over standard clinical and laboratory parameters has proved difficult to quantify. The additive contribution to diagnostic classification of a pragmatic, 15 min MSUS protocol was appraised in a large, unselected cohort of early arthritis clinic attendees.
Sphingosine kinase 1 (SphK1) and 2 (SphK2) have been shown contribute to synovial inflammation in animal models of arthritis. However, low levels of intracellular sphingosine-1 phosphate (S1P) were reported in fibroblast-like synoviocytes (FLS) from patients in the end stage of rheumatoid arthritis (RA) compared to normal FLS. Moreover, the S1P receptor-mediated chemokine synthesis was altered in ...
Clostridium is a diverse genus including more than 200 species involved in varied clinical presentations in infectious diseases. Septic arthritis caused by Clostridium sp. are however uncommon. We report here the first septic arthritis due to Clostridium tarantellae, formerly called Eubacterium tarantellae, in a patient under anti-TNF therapy.
Smoking is associated with increased risk for subsets of RA defined by the presence of anti-citrulline protein antibodies (ACPA) and rheumatoid factors (RF) and an interaction between smoking and HLA-DRB1 SE has been confined to risk of seropositive RA. We aimed to investigate the interplay between smoking and HLA-DRB1 SE with regard to risk of different RA subsets, based on RF and ACPA status.
Toreforant, an orally active histamine H-receptor antagonist, in patients with active rheumatoid arthritis despite methotrexate: mechanism of action results from a phase 2, multicenter, randomized, double-blind, placebo-controlled synovial biopsy study.
In a double-blind, placebo-controlled, multiple-dose study, we assessed the molecular mechanism of action of the selective histamine-4-receptor antagonist toreforant.
To investigate the natural history of central osteophytes (COs) by analyzing the structure and matrix composition of CO-associated cartilage using 3-T MRI at and 1-3 years before the onset of COs.
Theoretical risks of biologic agents remain under study.
Structural changes of bone and cartilage are the hallmarks of rheumatoid arthritis (RA) and psoriatic arthritis (PsA). Radiography can help in making diagnosis and in differentiating PsA and RA from other articular diseases. Radiography is still considered the preferred imaging method to assess disease progression, reflecting cumulative damage over time. The presence of bone erosions in RA is as a...
Molecular serum markers that can identify early reversible osteoarthritis (OA) in horses are lacking.
Interferon-γ (IFN-γ) is a versatile cytokine which broadly involves in the inflammatory diseases, mediating both immune activation and tolerance. Here, we aimed to investigate the role of IFN-γ in the initiation of adjuvant-induced arthritis (AIA).
To study the effect of intraarticular injection of crosslinked-chitosan in the treatment of knee osteoarthritis in rabbits.
The nature of model-based cost-effectiveness analysis can lead to disputes in the scientific community. We propose an iterative and collaborative approach to model development by presenting a flexible open-source simulation model for rheumatoid arthritis (RA), accessible to both technical and non-technical end-users.
Psoriatic arthritis (PsA) is a heterogeneous chronic inflammatory musculoskeletal condition with complex pathophysiology. In recent years, understanding of the pathogenesis of PsA has improved substantially. Several genetic and inflammatory factors have been identified and studied as targets for new biologic disease-modifying therapies. This review presents findings from a detailed literature asse...
The sirtuin family of NAD-dependent protein deacetylases promotes longevity and counteract age-related diseases. One of the major targets of Sirtuins are the FoxO family of transcription factors. FoxOs play a major role in the adaptation of cells to a variety of stressors such as oxidative stress and growth factor deprivation. Studies with murine models of cell-specific loss- or gain-of-function o...
Genetic studies have implicated both CD40 and tumour necrosis factor receptor-associated factor-1 (TRAF1) with rheumatoid arthritis (RA). CD40 signalling is known to be associated with TRAF1 expression, directly or indirectly; however, the detailed mechanisms of these interactions are not clear in RA, and in particular in fibroblast-like synoviocytes. This study aims to investigate this pathway an...
