Magilavy, M.D.: An Oral Spleen Tyrosine Kinase Inhibitor for ARTHRITIS RHEUMATOID Spleen tyrosine kinase is an intracellular cytoplasmic tyrosine kinase that is a significant mediator of immunoreceptor signaling in macrophages, neutrophils, mast cells, and B cells.1 In rodent types of collagen-induced arthritis,2 R788 , an oral prodrug that is rapidly changed into a potent and relatively selective inhibitor of Syk , 3 had potent antiinflammatory activity, suggesting a role for Syk inhibition in the treating rheumatoid arthritis. In a previous 12-week, ascending-dose, randomized, placebo-controlled trial4 involving 189 patients who had dynamic rheumatoid arthritis despite methotrexate therapy, a substantial decrease in arthritis activity and in serum degrees of interleukin-6 and matrix metalloproteinase 3 were observed in the two organizations that received the best doses of R788 , in comparison with the organizations that received placebo or the 50-mg dose of R788 twice daily.
Many lines of evidence suggest that a density shift in the distribution of Hounsfield models is unlikely to explain our findings. First, the associations we discovered between emphysema and interstitial lung abnormalities weren’t most prominent in the low lobes, where even more interstitial abnormalities are anticipated . Second, the reductions in emphysema noted in participants with interstitial lung abnormalities were paired with the physiological outcomes of reduced emphysema . Third, we observed inverse associations between the presence of interstitial lung abnormalities and clinically diagnosable COPD, a variable that’s independent of the measurement of emphysema with the use of HRCT.
