【摘要】 目的:分析腸易激綜合征(IBS)典型癥狀嚴(yán)重程度與血清25-羥維生素D[25-(OH)D]水平的相關(guān)性。方法:選取本院2018年1月-2020年1月收治的100例IBS患者作為試驗組,另選取同期于本院體檢的100例健康人員作為參照組。比較兩組血清25-(OH)D水平,比較試驗組中不同類型IBS患者血清25-(OH)D水平,分析IBS典型癥狀嚴(yán)重程度與血清25-(OH)D的相關(guān)性。結(jié)果:試驗組血清25-(OH)D水平為(17.62±2.62)ng/mL,低于參照組的(43.62±5.11)ng/mL(P<0.05)。試驗組維生素D缺乏與不足比例均高于參照組,維生素D充足比例低于參照組(P<0.05)。便秘型患者血清25-(OH)D水平明顯高于腹瀉型與混合型患者(P<0.05),混合型患者血清25-(OH)D明顯高于未定型患者(P<0.05)。IBS臨床癥狀嚴(yán)重程度評分系統(tǒng)(IBS-SSS)評分與血清25-(OH)D水平呈負(fù)相關(guān)(r=-0.516,P=0.021)。結(jié)論:IBS典型癥狀嚴(yán)重程度與血清25-(OH)D呈負(fù)相關(guān),血清25-(OH)D水平較低的IBS患者應(yīng)引起臨床重視。

[Abstract] Objective: To analyze the correlation between the severity of typical symptoms of irritable bowel syndrome (IBS) and serum 25-hydroxyvitamin D [25-(OH)D] levels. Method: A total of 100 IBS patients admitted in our hospital from January 2018 to January 2020 were selected as the experimental group, and 100 healthy persons examined in our hospital during the same period were selected as the reference group. Serum 25-(OH)D levels were compared between the two groups, serum 25-(OH)D levels of patients with different types of IBS in the experimental group were compared, the correlation between the severity of typical symptoms of IBS and serum 25-(OH)D was analyzed. Result: The serum 25-(OH)D level of the experimental group was (17.62±2.62) ng/mL, it was lower than (43.62±5.11) ng/mL of the reference group (P<0.05). The proportion of vitamin D lack and deficiency in the experimental group were higher than those in the reference group, and the proportion of vitamin D sufficient was lower than that in the reference group (P<0.05). The serum 25-(OH)D level of patients with constipation type was significantly higher than that of the patients with diarrhea-type and the mixed type (P<0.05). The serum 25-(OH)D of the patients with the mixed type was significantly higher than that in the the patients with unformed (P<0.05). IBS symptom severity scale (IBS-SSS) score was negatively correlated with serum 25-(OH)D level (r=-0.516, P=0.021). Conclusion: The severity of typical symptoms in IBS patients is negatively correlated with serum 25-(OH) D, the IBS patients with low serum 25-(OH)D should be paid attention to clinically.

腸易激綜合征(IBS)是一種臨床常見病,具體表現(xiàn)為便秘、腹瀉、腹脹、腹痛以及排便習(xí)慣改變等,嚴(yán)重影響了患者正常的生活、工作[1]。據(jù)不完全統(tǒng)計,世界范圍內(nèi)IBS的發(fā)生率高達(dá)25%,亞洲地區(qū)IBS發(fā)生率高達(dá)10%[2]。當(dāng)前,臨床治療IBS主要為對癥藥物治療,整體治療效果欠佳,將近1/3的IBS患者對常規(guī)藥物治療無反應(yīng)[3-4]。既往有研究表明維生素D具有調(diào)節(jié)鈣、磷代謝、免疫反應(yīng)、抗炎等作用,IBS患者機(jī)體維生素D水平明顯比健康人群低[5]?;诖?,本研究選取本院2018年1月-2020年1月收治的IBS患者100例,分析了IBS典型癥狀嚴(yán)重程度與血清25-羥維生素D[25-(OH)D]水平的相關(guān)性,現(xiàn)報道如下。
本研究中便秘型患者血清25-(OH)D水平(24.62±6.55)ng/mL明顯高于腹瀉型患者的(18.26±2.62)ng/mL與混合型患者的(18.86±2.64)ng/mL(P<0.05)。混合型患者血清25-(OH)D明顯高于未定型患者的(16.25±1.66)ng/mL(P<0.05)。表明腹瀉型、混合型、未定型IBS患者機(jī)體血清25-(OH)D水平要明顯比便秘型IBS患者低??紤]與膽汁酸吸收障礙有著密切關(guān)系,膽汁酸在脂溶性、脂質(zhì)維生素吸收的過程中發(fā)揮著至關(guān)重要的作用,而腹瀉型、混合型以及未定型的IBS患者脂溶性維生素以及其他的營養(yǎng)物質(zhì),吸收不良程度要比便秘型IBS患者重。本研究結(jié)果顯示,IBS-SSS評分與血清25-(OH)D水平呈負(fù)相關(guān)(r=-0.516,P=0.021)。分析如下:維生素D與IBS患者腸道黏膜輕度炎癥反應(yīng)以及內(nèi)臟敏感性有著密切聯(lián)系,輕度的炎癥反應(yīng)以及免疫活性,會加重IBS患者臨床癥狀。陳旭桑等[20]研究中認(rèn)為維生素D與IBS患者內(nèi)臟高敏性有著密切聯(lián)系,且肥大細(xì)胞參與了由于維生素D介導(dǎo)的IBS內(nèi)臟高敏性。
綜上所述,IBS患者典型癥狀嚴(yán)重程度與血清25-(OH)D水平呈負(fù)相關(guān)性,隨著IBS疾病的發(fā)生、發(fā)展,血清25-(OH)D水平會逐漸降低,故在IBS診斷及治療中,臨床應(yīng)加強血清25-(OH)D檢測,為治療方案的制定提供科學(xué)的參考依據(jù),最大限度改善患者預(yù)后,防止疾病進(jìn)展。
