CONCLUSIONS: Our study identifies that both IAS and PTI cause MCPj swelling, where PTI is almost as frequent as IAS as a cause of swelling. The reliability of PTI is at least as good as for IAS. PMID: 29998840 [PubMed - as supplied by publisher]
CONCLUSIONS: Our results demonstrate that two thirds of patients with PsA in Iceland who are treated with TNFi would not have qualified for the randomised clinical trials performed leading up to the registration of the medications. Further studies with regards to whether outcomes are different between those who met the inclusion criteria and those who did not remain to be performed.

CONCLUSIONS: Over a 10-year follow-up period, reclassification revealed significant heterogeneity in the diagnosis of seronegative RA. Therefore, seronegative arthritis should not be studied as a homogenous entity. PMID: 29998832 [PubMed - as supplied by publisher]
CONCLUSIONS: Overall, these results suggest that IL-17, TRAIL and TNF-α sustain bone tissue inflammation associated with decrease of calcified component. To do so, they act redundantly each other, to amplify the inflammatory response in the bone. In conclusion, unravelling novel molecular targets within the bone-cytokine network represents a platform for innovative treatment of bone diseases due to immunological diseases such as psoriatic arthritis.

CONCLUSIONS: Our data fail to show an increased prevalence of anti-glycan antibodies in AS or PsA patients. ACCA were found to be significantly higher in RA patients than in controls, and may serve as an inflammatory biomarker. The present results do not support a role for antiglycan antibodies as biomarkers for spondyloarthritis. PMID: 29998822 [PubMed - as supplied by publisher]
Abstract The complex pathogenesis of psoriatic arthritis (PsA) is still only partially understood; however, recently a greatly improved understanding of this disease has been achieved, especially with respect to the inflammatory processes of the entheses. Thus, the clinical aspects of enthesitis increasingly differentiate PsA from other autoimmune diseases and sharpen the unique pathological clinical picture of PsA. Better pathophysiological understanding and the development of different biomarker approaches will bolster early detection of PsA. Therefore, the successful early recognition of PsA and more reliable i...
Psoriasis is a systemic inflammatory disease associated with increased risk of comorbidities such as psoriatic arthritis, Crohn disease, malignancy, obesity and cardiovascular diseases. All these factors have a significant impact on the decision to use one therapy over another. The past decade has seen a paradigm shift in our understanding of the pathogenesis of psoriasis which has led to identification of new therapeutic targets. Several new drugs have gained FDA approval, expanding the psoriasis armamentarium but still a large number of patients continue to be untreated or undertreated.
ConclusionMales had a higher prevalence of SpA. Ankylosing spondylitis, psoriatic arthritis, and reactive arthritis were the most commonly diagnosed subtypes.
Publication date: Available online 11 July 2018Source: Autoimmunity ReviewsAuthor(s): Elena Generali, Tanima Bose, Carlo Selmi, J. Willem Voncken, Jan G.M.C. DamoiseauxAbstractSpondyloarthritides (SpA) include inflammatory joint diseases with various clinical phenotypes that may also include the axial skeleton and/or entheses. SpA include psoriatic arthritis, reactive arthritis, enteropathic arthritis and ankylosing spondylitis; the latter is frequently associated with extra-articular manifestations, such as uveitis, psoriasis, and inflammatory bowel disease. SpA are associated with the HLA-B27 allele and recognize T cells...
