Resistin 12.5-kDa cystein-rich protein name from the original observation that it induced insulin resistance in mice Predominant source : pph blood mononuclear cell, macrophages, BM cell In obesity : increased Positive correlation between resistin and BMI change

Visfatin B-cell maturation, inhibit neutrophil apoptosis 52-kDa protein enriched in the visceral fat of both human & mice plasma levels increase in obesity insulin-mimetic effects in cultured cells activates human leukocytes induces cytokine production IL-1, TNF-α, IL-6 The Journal of Immunology, 2007

27
현재까지의 IBD 관련 연구 상황 아직까지 conflicting data 연구 수가 적다. Resistin, visfatin 에 대한 연구가 부족 남 녀 구분, Clinical response 의 객관화 부족 치료 전 후의 비교 Data 부족
28
Study Aim & Design IBD 환자군과 정상 control 군 (age, sex, BMI matched) 사이에서 adipocytokine 의혈중 level 비교 IBD 환자에서 induction therapy 전 후의 혈중 adipocytokine 의 변화양상 확인 inflammatory marker 나 치료 및 예후 인자로 서의 가치평가. Prospective study
29
Body weight (for BMI) Height (for BMI) CD: CDAI UC: TWMAI(Truelove-Witt Index) Mayo Score CRP Blood samples –after a 12-hour overnight fasting –Lipid profiles (Total-C,HDL-C,LDL-C,TG) Measurements
30
Adiopcytokines –Reptin, adiponectin, resistin, visfatin –Blood sample after a 12-hour overnight fasting –Serum Serum :immediately separation(centrifuge) and store at – 70° until analysis Serum levels :measure by ELISA 각 환자의 Disease activity 평가 염증이 재발하여 Induction therapy 가 필요한 환자 0 주 (T0), 4 주 (T4) 평가
