Serum Elabela level is related to endoscopic activity index in patients with active ulcerative colitis.

Abstract

In ulcerative colitis patients, Elabela levels and the relation of Elabela with laboratory parameters is unknown. The purpose of this study was to investigate the serum Elabela levels in UC patients and its relationship with other clinical and laboratory findings. Forty-three patients with UC and 40 healthy controls (group I) similar in age and gender were included in the study. Routine patient history, physical examination, and laboratory tests were followed by analysis of serum Elabela levels. Endoscopic activity index (EAI) of patients with UC was calculated. There were two groups of patients: those in remission (group II) and with active disease (group III). Groups I, II, and III had 40, 22, and 21 participants, respectively. Serum Elabela levels were found to be 3.32 ± 1.25ng/mL in group I, 3.38 ± 0.88ng/mL in group II, and 5.48 ± 1.61ng/mL in group III. Comparing the serum Elabela levels, a statistically significant difference was found between three groups (p < 0.001). Serum Elabela level showed a significant and positive correlation with EAI, leukocyte count, and hs-CRP, while a negative correlation was found with hemoglobin levels in univariate analysis (p < 0.001, for each). In linear regression analysis, these parameters were found to be associated with EAI and hs-CRP (p = 0.049, β = 0.337, and p = 0.015, β = 0.396, respectively). Elabela concentrations in patients with active UC was significantly higher and was associated with EAI and hs-CRP. Blood Elabela concentrations can be useful in the diagnosis and follow-up of patients with active UC.
