Q: Abstract: OBJECTIVE Ankylosing spondylitis (AS) and spondyloarthropathy (SpA) are inflammatory diseases of unknown etiology. Various exogenous and endogenous (inherited) factors play a role in their development. Sulfasalazine (SSZ) is generally accepted as a disease modifying drug in the treatment of AS and SpA. Which part of SSZ, 5-acetylsalicylic acid (5-ASA, mesalazine) or sulfapyridine (SP), is the effective moiety is unknown. As the bowel, colon, and the ileum play an important role in the development of AS and SpA, it may be possible that 5-ASA is the effective moiety, with a similar mode of action as in the treatment of inflammatory bowel disease. To determine the efficacy of 5-ASA an open pilot study was done in 2 groups of patients with SpA. METHODS Twenty patients with SpA, who were taking SSZ, were switched to 5-ASA (Pentasa), and 19 patients with active SpA were treated with 5-ASA without previous administration of SSZ.
RESULTS In the first group, 17 (85%) patients responded with respect to the physician global clinical assessment compared to the previous SSZ treatment period; whereas in the second patient group a statistically significant improvement was obtained in erythrocyte sedimentation rate.
CONCLUSION The results support our hypothesis that 5-ASA might be the active moiety of SSZ in the treatment of SpA.. Title: Treatment of spondyloarthropathy with 5-aminosalicylic acid (mesalazine): an open trial.

Q: Abstract: Several lines of evidence suggest a role for the gut microbiome in type 1 diabetes. Treating diabetes-prone rodents with probiotics or antibiotics prevents the development of the disorder. Diabetes-prone rodents also have a distinctly different gut microbiome compared with healthy rodents. Recent studies in children with a high genetic risk for type 1 diabetes demonstrate significant differences in the gut microbiome between children who develop autoimmunity for the disease and those who remain healthy. However, the differences in microbiome composition between autoimmune and healthy children are not consistent across all studies because of the strong environmental influences on microbiome composition, particularly diet and geography. Controlling confounding factors of microbiome composition uncovers bacterial associations with disease. For example, in a human cohort from a single Finnish city where geography is confined, a strong association between one dominant bacterial species, Bacteroides dorei, and type 1 diabetes was discovered (Davis-Richardson et al. Front Microbiol 2014;5:678). Beyond this, recent DNA methylation analyses suggest that a thorough epigenetic analysis of the gut microbiome may be warranted. These studies suggest a testable model whereby a diet high in fat and gluten and low in resistant starch may be the primary driver of gut dysbiosis. This dysbiosis may cause a lack of butyrate production by gut bacteria, which, in turn, leads to the development of a permeable gut followed by autoimmunity. The bacterial community responsible for these changes in butyrate production may vary around the world, but bacteria of the genus Bacteroides are thought to play a key role..

Q: Abstract: PURPOSE The CpG island methylator phenotype (CIMP) may be associated with development of malignancy through coordinated inactivation of tumor suppressor and tumor-related genes (TRG) and methylation of multiple noncoding, methylated-in-tumor (MINT) loci. These epigenetic changes create a distinct CIMP pattern that has been linked to recurrence and survival in gastrointestinal cancers. Because epigenetic inactivation of TRGs also has been shown in malignant melanoma, we hypothesized the existence of a clinically significant CIMP in cutaneous melanoma progression. EXPERIMENTAL DESIGN The methylation status of the CpG island promoter region of TRGs related to melanoma pathophysiology (WIF1, TFPI2, RASSF1A, RARbeta2, SOCS1, and GATA4) and a panel of MINT loci (MINT1, MINT2, MINT3, MINT12, MINT17, MINT25, and MINT31) in primary and metastatic tumors of different clinical stages (n=122) was assessed.
RESULTS Here, we show an increase in hypermethylation of the TRGs WIF1, TFPI2, RASSF1A, and SOCS1 with advancing clinical tumor stage. Furthermore, we find a significant positive association between the methylation status of MINT17, MINT31, and TRGs. The methylation status of MINT31 is associated with disease outcome in stage III melanoma.
CONCLUSIONS These findings show the significance of a CIMP pattern that is associated with advancing clinical stage of malignant melanoma. Future prospective large-scale studies may determine if CIMP-positive primary melanomas are at high risk of metastasis or recurrence..
