Two New Studies Provide Further Evidence for the Link Between Psoriasis and Inflammatory Bowel Disease

New cytokines and T cells populations, as IL-17A, IL-22, and Th22 cells, could play an important pathogenetic role in psoriasis and IBD. Several genetic correlations between psoriasis and IBD have been reported thanks to Genome Wide Association Studies (GWAS) that have identified 13 psoriasis susceptibility loci (called PSORS1-13) and 28 IBD susceptibility loci (called IBD1-28) (Figure 1). Two loci appear to be more important thus needing further studies. Crohn’s disease (CD) and ulcerative colitis (UC), the two predominant types of inflammatory bowel disease (IBD), are chronic relapsing inflammatory disorders of the gastrointestinal tract. Prior studies examining the association between psoriasis and risk of CD or UC have been conflicting20, 22 24 and have been limited by their cross-sectional or retrospective design, which obscures the temporal relationship between psoriasis and onset of IBD. 21 Prior studies examining the association between psoriasis and risk of CD or UC have been conflicting20, 22 24 and have been limited by their cross-sectional or retrospective design, which obscures the temporal relationship between psoriasis and onset of IBD. However, the link between psoriasis and IBD is currently far from clear. In conclusion, the study by Lolli et al. provides a new perspective in terms of understanding the complex mechanisms underlying IMID and, in general, the immune system. Such further studies may lead to the discovery of new methods for early diagnosis and new tailored therapeutic agents for the control and restoration of a healthy immune system in patients with IMID. Evidence for two psoriasis susceptibility loci (HLA and 17q) and two novel candidate regions (16q and 20p) by genome-wide scan.

Despite the common manifestation, data on the frequency of EIM in large IBD populations are limited so far and there is especially a paucity of studies evaluating EIM-associated risk factors. The correlation between disease activity and frequency and type of EIM is further illustrated in Tables 2 and 3. Table 2 – EIM in CD patients in relation to disease activity. Inflammatory bowel diseases and psoriasis may be related to each other. Two New Studies Provide Further Evidence for the Link Between Psoriasis and Inflammatory Bowel Disease. The innate arm of the immune system provides an initial, rapid response to microbes.

Psoriasis (OMIM 177900) is an ancient and universal inflammatory disease, initially described at the beginning of medicine in the Corpus Hippocraticum. (besides arthritis of small joints) is the inflammatory bowel disorder Crohn disease (2). Psoriasis can begin at any age, although epidemiological studies demonstrate that it most commonly appears for the first time between the ages of 15 and 25 years (3). Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine. The way doctors can tell the difference between Crohn’s disease and UC is the location and nature of the inflammatory changes. Further evidence of the role of gut flora in the cause of inflammatory bowel disease is that IBD-affected individuals are more likely to have been prescribed antibiotics in the 2-5 year period before their diagnosis than unaffected individuals. Some preliminary studies have suggested benefits similar to those in Clostridium difficile infection but a review of use in IBD shows that FMT is safe, but of variably efficacy. The striking relationship between IBD and AS has been recognized for many years: up to 10 of IBD patients develop AS, and, vice versa, IBD commonly develops in patients primarily diagnosed with AS 3. Danoy and co-workers provide two additional links to the Th17 pathway.

What is currently known about the causes of this inflammatory autoimmune disease? Her diverse work in psoriasis investigates the role and importance of interleukin-17C (IL-17C) in the onset and escalation of the disease; the link between psoriasis and heart attack and stroke; NIH researchers identify new gene variants associated with risk for complex inflammatory syndrome. Two years ago, the research team identified gene associations at two other specific chromosome locations, or loci. These newly discovered genetic associations provide a link between Behcet’s disease and other more common illnesses, and thereby suggest new therapies for Behcet’s disease. The genetic associations have helped classify Behcet’s disease with more common inflammatory conditions such as psoriasis, inflammatory bowel disease and a form of spinal arthritis called ankylosing spondylitis. Rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis are immune-mediated inflammatory diseases with similarities in pathophysiology, and all can be treated with similar biological agents. Data on patients with RA or IBD were collected from two registries in which patients treated with biologic medication were enrolled. More recent treatments include biologic drugs of which anti-tumor necrosis factor (anti-TNF) agents are the most frequently used 1, 2. In most studies focusing on the relationship between gender and RA, women were found to have higher disease activity scores, more pain and greater loss of function, both in early and established disease 3 6. Many studies report that omega-3 fatty acids may help reduce blood pressure. However, a significant link between mother’s fish intake and child eczema was lacking. Many studies have looked at the possible benefit of omega-3 fatty acids in people who have inflammatory bowel diseases, such as ulcerative colitis and Crohn’s disease, when used with standard therapy. Several studies looking at psoriasis and fish oil do not provide enough reliable evidence to form a clear conclusion. Psoriatic arthritis – a seronegative inflammatory arthritis, which between 7-40 of people with psoriasis will develop. There is no strong evidence that any of the interventions have a disease-modifying effect or impact beyond improvement of the psoriasis itself. Treatment with narrow-band UVB phototherapy can be given three or two times a week. Besides individual studies, recent meta-analysis of GWAS has also enabled the identification of dozens of susceptibility loci for T1D (Cooper et al. IFIH1 exerts its influence through the apoptosis of virally infected cells in antiviral immune responses, which may in turn support the notion that there is a connection between viral infections and the pathogenesis of T1D (Knip et al. As a result, the IL2-IL21 association strengthened further and they found strong evidence for the following loci: BACH2 (as we described previously (Grant et al.
