Celiac disease is an immune-mediated enteropathy due to a permanent sensitivity to gluten in genetically susceptible people. Iron-deficiency anemia is the most widely experienced anemia in humans. Iron-deficiency anemia additionally is a common extra intestinal manifestation of celiac disease.
To investigate correlation between tTg levels and histological alterations and then to determine the prevalence of celiac disease in Center and South area patients of Iran with iron deficiency anemia.
A total of 402 patients aged 12-78 years who presented with iron-deficiency anemia were included in this study. Hemoglobin, mean corpuscular volume and serum ferritin were determined. Venous blood samples for anti-tissue transglutaminase antibody immunoglobuline A and G were obtained from these patients. Upper gastrointestinal endoscopy was recommended to patients who had positive serology.
Of 402 patients with iron-deficiency anemia, 42 (10.4%) had positive serology for celiac disease. The small intestine biopsy of all patients with positive serology showed pathological changes (Marsh I, II & III). There was not significant difference in the mean hemoglobin level between iron-deficiency anemia patients with celiac disease and without celiac disease, duodenal biopsy results did not show significant relationship between the severity of pathological changes and levels of anti-tTG IgG (P -value: 0/869) but significant relationship was discovered between pathological changes and levels of anti-tTG IgA (P -value: 0/004).
Screening of celiac disease by anti-tissue transglutaminase antibody should be completed as a routine investigation in patients with iron-deficiency anemia. Also physicians must consider celiac disease as a possible reason of anemia in all patients with iron deficiency anemia.
乳糜泻是一种免疫介导的肠病,是由于遗传易感性个体对麸质产生永久性敏感所致。缺铁性贫血是人类最常见的贫血类型。此外,缺铁性贫血还是乳糜泻常见的肠外表现。
研究组织转谷氨酰胺酶(tTg)水平与组织学改变之间的相关性,进而确定伊朗中部和南部地区缺铁性贫血患者中乳糜泻的患病率。
本研究纳入了402例年龄在12 - 78岁之间、患有缺铁性贫血的患者。测定了血红蛋白、平均红细胞体积和血清铁蛋白。采集这些患者的静脉血样本检测抗组织转谷氨酰胺酶抗体免疫球蛋白A和G。对血清学阳性的患者建议进行上消化道内镜检查。
在402例缺铁性贫血患者中,42例(10.4%)乳糜泻血清学呈阳性。所有血清学阳性患者的小肠活检均显示病理改变(马什I、II和III级)。患有乳糜泻和未患乳糜泻的缺铁性贫血患者之间的平均血红蛋白水平无显著差异,十二指肠活检结果显示病理改变的严重程度与抗tTG IgG水平之间无显著关系(P值:0/869),但病理改变与抗tTG IgA水平之间存在显著关系(P值:0/004)。
应将抗组织转谷氨酰胺酶抗体筛查乳糜泻作为缺铁性贫血患者的常规检查。此外,医生必须将乳糜泻视为所有缺铁性贫血患者贫血的可能原因。
