【摘要】 目的:回顧性觀察糖尿病酮癥酸中毒患者血清CA19-9水平,分析糖尿病急性代謝紊亂狀態(tài)下CA19-9升高的特點。方法:選取糖尿病酮癥酸中毒患者73例和血糖控制差(糖化大于7.5%)的糖尿病非酮癥酸中毒患者209例,對其性別、年齡、糖尿病病程、體重指數(shù)、HbA1c、CA19-9水平進行分析。結果:(1)酮癥酸中毒組平均CA19-9水平29.7(57.8~15.35)U/mL,顯著高于非酮癥酸中毒組10.1(19.65~5.40)U/mL,比較差異有統(tǒng)計學意義(P<0.01);前者CA19-9升高的比例為39.7%,而后者為7.7%(P<0.01),兩者比較差異有統(tǒng)計學意義。(2)CA19-9升高的45例患者中數(shù)值在200 U/mL以內者占95.6%,其中10例患者病情糾正后復查CA19-9均呈下降趨勢。結論:糖尿病患者CA19-9水平在酮癥酸中毒狀態(tài)下較非酮癥酸中毒狀態(tài)下可更明顯升高。

The Alteration of Serum CA19-9 Levels in Patients with Diabetic Ketoacidosis/LU Xun-liang.//Medical Innovation of China,2014,11(28):016-018
【Abstract】 Objective: To retrospectively observe the alteration of serum CA19-9 levels in patients with diabetic ketoacidosis (DKA) compared to diabetics without DKA. Method: Seventy-three patients with DKA(DKA group) and 209 diabetics under dissatisfied glucose control (non-DKA group, HbA1c>7.5%) were enrolled. Records of gender, age, diabetic duration, BMI, HbA1c, CA19-9 level were collected. The levels of serum CA19-9 were compared between the two groups. Result: (1) Average CA19-9 level was significantly higher in DKA group 29.7(57.8-15.35)U/mL than that in non-DKA group 10.1(19.65-5.40)U/mL (P<0.01), as well as the percentage of positive CA19-9 level (39.7% and 7.7%, P<0.01). (2) The abnormal values were in range of 37.1-674.5 U/mL, mainly distributed within 200 U/mL(95.6%). Conclusion: Slight to moderate elevations of CA19-9 levels are more frequently found in DKA patients than diabetics under poor glucose control, as well as significant higher levels.

糖尿病和腫瘤的關系近年來備受關注,尤其是糖尿病與胰腺癌之間的相互關系近年來成為研究熱點[1-2]。因此,對糖尿病患者進行腫瘤標志物檢測已成為常規(guī)篩查手段。糖類抗原CA19-9(CA19-9)是臨床最常用的腫瘤標志物之一,它對胰腺癌診斷的特異性和敏感性均超過70%,但由于它也可以在很多非腫瘤性疾病中升高[3-5],包括肝硬化、急慢性肝炎、膽道梗阻、某些甲狀腺疾病、某些肺部良性疾病以及糖尿病,因此在臨床應用中仍需結合病情分析其升高的原因。
人們早就注意到CA19-9水平在糖尿病患者中升高的現(xiàn)象,以往的研究報道已給出以下結論:糖尿病人群CA19-9水平高于正常健康人群;血糖控制欠佳糖尿病患者CA19-9水平高于血糖控制良好者;糖化血紅蛋白可能是影響因素[6-8]。在臨床工作中,筆者注意到糖尿病酮癥酸中毒患者似乎更易出現(xiàn)CA19-9升高的現(xiàn)象,而目前關于CA19-9在酮癥酸中毒狀態(tài)下升高情況的研究報道很少,為明確該急性代謝紊亂狀態(tài)是否影響了CA19-9水平,本研究通過回顧性觀察,并與血糖控制欠佳的非酮癥酸中毒患者比較,總結了酮癥酸中毒狀態(tài)下CA19-9水平升高的特點并嘗試解釋這些現(xiàn)象的可能原因。……p>
