In this study ixekizumab and secukinumab patients had similar treatment patterns. It was also surmised that the use of adjunctive pain and anti-inflammatory medications were similar between therapies. In coming to this conclusion investigators aimed to compare treatment patterns and use of pain and anti-inflammatory medications between patients with PsA initiating ixekizumab and secukinumab in two cohorts of patients from…(add here where is the population coming from).

Many cytokines associated with RA pathogenesis and pain are affected directly or indirectly by the JAK/STAT pathway, therapeutic targeting may offer promise. Having better understanding of these mechanisms can help clinicians make treatment decisions that optimise the control of inflammation and pain. However, pain in patients with RA is complex and involves multiple driving mechanisms that may differentially occur over time in different people. Although one known constant is that nociceptive ac...

Itacitinib is an orally active JAK inhibitor and effectively delayed disease onset, reduced symptom severity, and accelerated recovery of inflammatory diseases in mouse models. Covington M et al demonstrated itacitinib’s high selectivity for JAK 1, its inhibition on IL-2 induced T cell proliferation and JAK/STAT signalling, its ability to also inhibit of the JAK/STAT pathway in response to IL-6 stimulation, and its effect on rat adjuvant induced arthritis model. The study used recombinant enzym...

TOF demonstrated a dose-dependent promotion of human mesenchymal stromal cell (hMSC) recruitment under hypoxia, while inhibiting recruitment under normoxia. TOF also dose-dependently enhances osteogenic differentiation of hMSCs and reduces osteoclast differentiation and activity. As people age, they are more likely to suffer from fractures and delayed bone healing, as well as degenerative joint diseases or osteoporosis. Bone metabolism and fracture healing may be negatively affected by underlyin...

Baricitinib (BARI) was associated with increased lipid levels; baseline statins did not alter these profiles. The introduction of statins during treatment reduced total cholesterol and LDL-C.The use of anti-inflammatory drugs in RA patients has been shown to alter lipid levels and is associated with reduced atherogenic risk. Increases in lipid levels, specifically HDL-C and LDL-C, have been observed in Phase 2 BARI studies1.This study analysed data from seven randomised RA Phase 2/3 studies of ...

IL-37, a member of the IL-1 family, has recently been characterised as a fundamental inhibitor of innate inflammation. This study examines the effects of recombinant IL-37 on joint inflammation and pathology in a mouse model of arthritis, and also explores its potential in the treatment of human joint inflammation.In this mouse model of experimental arthritis, short-term, low-dose treatment with IL-37 suppressed joint and systemic inflammation. Wild-type mice received three intraperitoneal doses...

Clinical Relevance of VPAC1 Receptor Expression in Early Arthritis: Association with IL-6 and Disease Activity

VPAC1 and VPAC2 both mediate anti-inflammatory and immunoregulatory responses in RA. Both these are receptors of vasoactive intestinal peptide (VIP), a broadly distributed peptide found in neural, endocrine and immune cells, which triggers biological response when interacting with the aforementioned receptors. It has recently been described in Martinez et al. that those patients with low levels of VIP have worse disease outcome.1This study analyzed 250 blood samples from the Princesa early Arthr...

A team of scientists at Trinity College Dublin and the University of Queensland Australia, led by Professor Luke O'Neill, have identified a key molecule that may result in the development of new anti-inflammatory therapies for diseases such as: cryopyrin-associated periodic syndrome (CAPS), multiple sclerosis, type 2 diabetes, Alzheimer’s disease and atherosclerosis.

Professor O'Neill and his team have identified MCC950 as a potent, selective, small-molecule inhibitor of the NLRP3 infla...
