摘要 潰瘍性結腸炎是我國消化系統的常見病,由于其具有易復發、病程遷延不愈、癌變傾向等特點,嚴重影響患者的生命質量。中性粒細胞與淋巴細胞比值(NLR)和血小板與淋巴細胞比值(PLR)是新型炎癥標志物,越來越多的研究發現NLR、PLR與潰瘍性結腸炎具有相關性。本文就NLR、PLR在潰瘍性結腸炎中臨床價值的研究進展作一綜述。
關鍵詞 結腸炎, 潰瘍性; 中性粒細胞與淋巴細胞比值; 血小板與淋巴細胞比值

Abstract Ulcerative colitis is a common disease of the digestive system in China, which seriously affects the quality of life of patients due to its disease characteristics, such as easy recurrence, repeated course of disease and carcinogenic tendency. Neutrophil?to?lymphocyte ratio (NLR) and platelet?to?lymphocyte ratio (PLR) are considered as new inflammatory biomarkers, which have been found to be related with ulcerative colitis. This article reviewed the clinical value of NLR and PLR in ulcerative colitis.
Key words Colitis, Ulcerative; Neutrophil?to?Lymphocyte Ratio; Platelet?to?Lymphocyte Ratio
潰瘍性結腸炎(ulcerative colitis, UC)是炎癥性腸病的主要亞型之一,目前認為其發病機制是遺傳易感性、異常免疫反應、腸黏膜屏障、腸道微生態失調等多種因素作用的結果。UC的臨床特征是活動期與緩解期交替,臨床活動分期和嚴重程度的判斷對于臨床診治至關重要,早期識別UC患者的疾病分期可降低UC患者的手術率和死亡率,有助于改善患者預后和生命質量。目前比較準確地評估UC嚴重程度和臨床活動性的方法主要是結腸鏡檢查,由于其具有侵入性、患者耐受性差等缺陷,在臨床中的應用往往受到限制。此外,目前常規檢測提示炎癥反應和臨床活動性的指標包括C反應蛋白(C?reactive protein, CRP)、紅細胞沉降率(erythrocyte sedimentation rate, ESR)、白細胞等,但缺乏特異性且合并其他感染因素。因此,尋找一種易獲得、簡便、敏感性和特異性均較好的血清學標志物評估UC病情很有必要。近年大量研究揭示了血常規中白細胞亞型及其相關比值與UC疾病活動性相關,可輔助評估患者的腸黏膜炎癥反應程度,具有一定的穩定性,聯合傳統炎癥標志物可提高診斷效能,同時對于UC療效的監測具有一定臨床價值。……
