多数学者认为D—木糖吸收试验仍是一种重要且较敏感的检查方法。然而,采用一小时血木糖测定还是用五小时尿木糖测定尚存在不同观点。为此,作者等对111例病人进行125次D—木糖试验,包括男50例,平均43.9岁,女61例,平均47.7岁,多数病人还同时进行内镜和X线检查及其他吸收试验。24例病人(D组)有14例获最后诊断,其中乳糜泻者2例,可能为细菌过度繁殖者10例。受试者禁食一夜后口服D—木糖25克,一小时后采血,随后及一小时后分别饮入二杯温开水。摄入木糖后收集5小时的尿液,测定尿和血清中木糖浓度。结果:以血木糖>25mg/dl、尿木糖>4.5g/5hr为正常值。结果为71次检查两者均正常。29次检查两者均异常。1例患者尿木糖值正常(4.8g/5hr),而血清值异常(20.3mg/dl)。24次试验(D组)血清木糖浓度正常而尿本糖值异常(5小时尿木糖均值为3.2±0.9)。此组病人的其他吸收试验结果为,作粪便脂肪测定11例中9例异常(>6g/24hr);20例行~(14)C—甘氨胆酸—呼气试验中15例(75%)异常。21例作粪便脂肪测定和/或行~(14)C—甘氨胆酸—呼气试验者中19例(90.5%)至少有
Most scholars believe that D-xylose absorption test is still an important and more sensitive method of inspection. However, there are different points of view when using the one-hour blood xylose assay or the five-hour urine xylose assay. To this end, the author of 125 patients on 111 cases of D-xylose test, including 50 males, average 43.9 years old, 61 females, an average of 47.7 years of age, most patients also endoscopic and X-ray examination and other absorption test . Of the 24 patients (group D), 14 were finally diagnosed, with 2 cases of celiac disease, possibly 10 cases of bacterial over-breeders. Subjects were fasted overnight overnight 25 grams of D-xylose, one hour after blood collection, and then one hour later were drank two cups of warm water. Urine was collected for 5 hours after ingestion of xylose, and urine and serum xylose concentrations were measured. Results: The normal value of blood xylose> 25mg / dl, urinary xylose> 4.5g / 5hr. The result was 71 tests both were normal. 29 tests both abnormal. One patient had normal urinary xylose values (4.8 g / 5 hr) and abnormal serum values (20.3 mg / dl). Twenty-four trials (group D) had normal serum xylose concentrations and abnormal urine sugar values (mean of 5 hours urinary xylose 3.2 ± 0.9). Other absorption test results of this group of patients were as follows: 9 cases (> 6g / 24hr) in 11 cases of stool fat measurement and 15 cases (75%) in 20 cases of ~ (14) C-glycocholate- )abnormal. Twenty-one of the 21 patients (90.5%) with stool fat and / or C14-glycocholic acid-breath test had at least
