摘要
目的探讨婴幼儿腹泻与乳糖不耐受的关系及去乳糖饮食治疗的疗效。方法采用醋酸铅法检测粪便乳糖的含量;应用ELISA双抗体夹心法测定粪便轮状病毒抗原;分组治疗婴幼儿腹泻,观察疗效。结果婴幼儿腹泻中乳糖不耐受的发生率为61.6%。其中<1岁乳糖不耐受的发生率为71.4%;>1岁乳糖不耐受的发生率为41.7%,二者发生率比较差异有统计学意义。RVAg(+)乳糖不耐受的发生率62.7%。RV(-)乳糖不耐受的发生率59.1%,二者发生率比较差异无统计学意义。对婴幼儿腹泻乳糖不耐受,去乳糖饮食疗效明显高于常规西药治疗;对轮状病毒肠炎合并乳糖不耐受,去乳糖饮食疗效高于常规西药治疗。结论婴幼儿腹泻中乳糖不耐受发生率比较高,以<1岁婴儿为多见;对婴幼儿腹泻乳糖不耐受给予去乳糖饮食疗效肯定,值得临床推广。
Objective To study the relationship between infantile diarrhea and lactose intolerance, and the curative effect of lactose free diet. Methods The content of lactose in dejecta was determined with lead acetate method. The rotavirus Ag was determined with ELISA. Infants with diarrhea were divided into lactose free diet group and routine western medidine group, and the curative effect of the two groups was observed. Results The lactose intolerance rate in infants was 61.6 %. The lactose intolerance rate was 71.4 % in infants aged less than oneyear. and 41.7 % in infants aged more than one- year; there showed statistical differences, The lactose intolerance rate of RVAg , （＋） was 62.7 %. and the lactose in- tolerance rate of RV （ - ） was 59.1% ; there was no statistical difference between them. The curative effect of actose free diet group was better than that of western medicine group in infants with diarrhea and lactose intolerance and in infants with ro- tavirus enteritis complicated with lactose intolerance. Conclusions The lactose intolerance rate is higner in infants with diarrhea, especially in infants less than I year of age. Non lactose diet has notable curative effects in infants with diarrhea, and it is worthily recommended in clinical application.
