Jejunal biopsy and hydrogen breath test were performed in 57 children, 34 having coeliac disease and 23 with other forms of malabsorption. In children affected by coeliac disease there was a gradually increasing incidence of positive findings with the H2 breath test as villous damage progressed. In the group of subtotal villous atrophy age dependence was also observed, the majority of positive results occurring below three years of age. In the non-coeliac group the most frequent cause of the positive finding was Giardia lamblia infestation. Among 27 cases with lactose malabsorption confirmed by a positive hydrogen breath test only 11 had diarrhoea. The test proved to be useful in differentiating between the contaminated intestine syndrome and malabsorption due to reduced absorptive surface.
对57名儿童进行了空肠活检和氢呼气试验，其中34名患有乳糜泻，23名患有其他形式的吸收不良。在患有乳糜泻的儿童中，随着绒毛损伤的进展，氢呼气试验阳性结果的发生率逐渐增加。在全绒毛萎缩组中也观察到年龄依赖性，大多数阳性结果出现在3岁以下。在非乳糜泻组中，阳性结果最常见的原因是贾第鞭毛虫感染。在27例经氢呼气试验证实为乳糖吸收不良的病例中，只有11例有腹泻。该试验被证明有助于区分污染肠综合征和由于吸收表面减少引起的吸收不良。
