Ulcerative colitis (UC) and Crohn's disease (CD) are two major forms of inflammatory bowel disease (IBD), which is an inflammatory disease.Studies have shown that adipose tissue and inflammation play important roles in the pathogenesis of IBD. C1q/TNF-related protein-3 (CTRP3) is a newly discovered adipokine playing a substantial role during inflammatory process, and for the first time in the present study, serum levels of this adipokine were measured in the UC and CD patients. This casecontrol study included 70 control, 50 UC, and 50 CD patients who were diagnosed by standard criteria. Serum levels of adiponectin, IL-6, TNF-α, TGF-β, and CTRP3 were evaluated using ELISA kits.
Background
Meteorin-like (Metrnl) is an adipokine with insulin sensitizing and anti-inflammatory properties that has been discovered recently. The relation among Metrnl, Inflammatory Bowel Disease (IBD), and obesity has been unexplored yet.
Methods
The present study was conducted on 54 healthy control, 42 Ulcerative Colitis (UC), and 43 Crohn’s disease (CD) patients who were diagnosed by pathological examination. In all participants, serum levels of adiponectin, Metrnl, interleukin (IL)-6, and Tumor necrosis factor (TNF-α) were measured using ELISA kits.
Results
Metrnl concentration was considerably lower in both UC (85.25 ± 36.55 pg/mL) and CD (76.93 ± 27.92 pg/mL) patients in comparison to control (107.52 ± 35.33 pg/mL). In addition, it was seen that both patient groups have a decreased level of adiponectin compared to the controls. Besides that, the level of IL-6 and TNF-α were significantly greater in the patient groups. Moreover, the result showed that the level of Metrnl is inversely correlated with body mass index (BMI) in the controls and the patients. Metrnl levels are also inversely associated with IL-6, and TNF-α in both of the patient groups.
Conclusions
The current study is the first one reporting the decreased levels of Metrnl in serum among patients with IBD, which is inversely related with BMI, TNF-α, and IL-6. These results suggested a possible relation of Metrnl with the pathogenesis of IBD, particularly through inflammatory process, although further studies are warranted to dissect the possible mechanism.

AbstractBackground
Meteorin-like (Metrnl) is a newly discovered adipokine with the anti-inflammatory and insulin sensitizing properties. Accordingly, Metrnl regulates glucose tolerance, enhances metabolism in body tissues, and induces thermogenesis in white adipose tissue. However, the correlation among Metrnl, IBD, and obesity still remains unexplored.
Methods
The present study was conducted on 54 healthy control, 42 Ulcerative Colitis (UC), and 43 Crohn's disease (CD) patients who were diagnosed by pathological examination. In these patients, serum levels of adiponectin, Metrnl, IL-6, and TNF-α were measured using ELISA kits.
Results
Metrnl concentration significantly decreased in both of the UC (85.25 ± 36.55 pg/mL) and CD (76.93 ± 27.92 pg/mL) patients compared to control group (107.52 ± 35.33 pg/mL). Similarly, adiponectin has also decreased in these two patient groups compared to the controls. However, IL-6 and TNF-α significantly increased in both of the patient groups. Moreover, Metrnl indicated an inverse relationship with BMI in the controls and both of the patient groups. In addition, there was an inverse correlation among Metrnl, IL-6, and TNF-α in both of the patient groups.
Conclusions
The current study is the first one reporting the decreased Metrnl serum level in the patients with IBD, which is inversely related to BMI, TNF-α, and IL-6. These results suggested a possible role for Metrnl in the pathogenesis of IBD, particularly through inflammation modulating.
