Tropical sprue was considered to be the most important cause of malabsorption in adults in India. However, several reports indicate that celiac disease is now recognized more frequently.
We analyzed the clinical presentation, endoscopic and histological features of 94 consecutive patients (age >12 years) with chronic diarrhea and malabsorption syndrome. The spectrum of disease in these patients and features differentiating celiac disease and tropical sprue are reported here.
Celiac disease (n = 61, 65%) was the most common cause of malabsorption followed by tropical sprue (21, 22%). Other conditions including cyclosporiasis (3), Crohn's disease (2), common variable immunodeficiency (2), lymphangiectasia (1), William's syndrome (1), and idiopathic malabsorption (3) accounted for the remainder. A greater number (21, 34%) of patients with celiac disease than those with tropical sprue (4, 19%) presented with atypical manifestations. Patients with celiac disease were younger (p = 0.001), more often had anemia, (p = 0.001), scalloping of folds (p = 0.001), moderate (p = 0.02) or severe (p = 0.001) villous atrophy, higher grade of intraepithelial lymphocytic infiltration (p = 0.001), crypt hyperplasia (p = 0.001), cuboidal (p = 0.001) and pseudostratified (p = 0.009) surface epithelial cells, and diffuse (p = 0.001) epithelial damage. In comparison, patients with tropical sprue were older and more often had normal duodenal folds, normal villi, tall columnar epithelial cells and focal epithelial damage.
Celiac disease was the most frequent cause of malabsorption syndrome in this series of patients. There are significant clinical and histological differences between celiac disease and tropical sprue.
热带口炎性腹泻曾被认为是印度成年人吸收不良的最重要原因。然而,一些报告表明,现在乳糜泻的诊断更为常见。
我们分析了94例(年龄>12岁)慢性腹泻和吸收不良综合征患者的临床表现、内镜及组织学特征。本文报告了这些患者的疾病谱以及区分乳糜泻和热带口炎性腹泻的特征。
乳糜泻(n = 61,65%)是吸收不良最常见的原因,其次是热带口炎性腹泻(21例,22%)。其他情况包括环孢子虫病(3例)、克罗恩病(2例)、常见变异型免疫缺陷病(2例)、淋巴管扩张症(1例)、威廉姆斯综合征(1例)和特发性吸收不良(3例),占其余病例。与热带口炎性腹泻患者(4例,19%)相比,更多乳糜泻患者(21例,34%)表现为非典型症状。乳糜泻患者更年轻(p = 0.001),更常出现贫血(p = 0.001)、皱襞扇贝样改变(p = 0.001)、中度(p = 0.02)或重度(p = 0.001)绒毛萎缩、上皮内淋巴细胞浸润程度更高(p = 0.001)、隐窝增生(p = 0.001)、立方形(p = 0.001)和假复层(p = 0.009)表面上皮细胞以及弥漫性(p = 0.001)上皮损伤。相比之下,热带口炎性腹泻患者年龄更大,十二指肠皱襞、绒毛更常正常,上皮细胞为高柱状,且存在局灶性上皮损伤。
在这组患者中,乳糜泻是吸收不良综合征最常见的病因。乳糜泻和热带口炎性腹泻在临床和组织学上存在显著差异。
