This study shows for the first time that in an animal model of MS, the insulin sensitizer, rosiglitazone, improves the metabolic profile and increases plasma levels of adiponectin and its gene expression. It is possible therefore that rosiglitazone exerts its beneficial effects by increasing the levels of adiponectin.

Obesity and its related disorders, glucose intolerance, hypertension and hyperlipidemia, collectively named the metabolic syndrome, result in substantial cardiovascular morbidity and mortality. Recent data point to several underlying regulatory mechanisms through which obesity links these various outcomes. Adipose tissue is now understood to function not merely as a passive energy storage depot but as an active endocrine organ, producing a variety of bioactive substances termed adipocytokines. Adiponectin, an adipocytokine first described as the most abundant protein produced by adipocytes, appears to serve as a central regulatory protein in many of the physiologic pathways controlling lipid and carbohydrate metabolism, and to mediate various vascular processes. Adiponectin displays both anti-inflammatory and antiatherogenic properties. Unlike other adipocytokines, its levels are paradoxically decreased in obesity and insulin-resistance states including metabolic syndrome and diabetes, as well as hypertension and coronary artery disease. This review will detail the relationship of adiponectin to various features of obesity and insulin-resistance syndromes, as well as its relationship to the cardiovascular complications of these disorders.

Background and the Study Aim: Crohn’s disease (CD) is a chronic inflammatory disorder defined as a transmural inflammation of the bowel wall, affecting the small and large intestine. The Capsule Endoscopy Crohn’s Disease Activity Index (CECDAI or Niv score) was devised to measure mucosal disease activity. We extended the Niv score to the colon and have a comprehensive view of the whole intestine. Methods: We evaluated 3 parameters of intestinal pathology: A, Inflammation; B, Extent of disease; C, Presence of strictures. The scoring formula is as follows: CEDCAIic=(A1×B1+C1)+(A2×B2+C2)+(A3×B3+C3)+(A4×B4+C4) (1=proximal small bowel, 2=distal small bowel, 3=right colon, 4=left colon). Results: The median CECDAIic score was 15.5 (range, 0 to 42), and the mean±SD score was 17.2±11.5. The CECDAIic scores per patient were similar among the 5 observers. Kendall’s coefficient of concordance was high and significant for almost all the parameters examined except for strictures in the proximal small bowel and distal colon. Nevertheless, the coefficients for the small bowel and for the whole intestine were high, 0.85 and 0.77, P<0.0001, respectively. Conclusions: We established a new score, the CECDAIic of the small-bowel and colonic CD. We offer this easy, user-friendly score for use in randomized controlled trials and in the clinical follow-up of CD patients.
