RESUMEN
Objective To investigate the clinical effect of L -glutamine gung shimron acid sodium in combi-nation with esomeprazole in the treatment of pediatric peptic ulcer and its effects on immunological function and intes-tinal flora.Methods 120 patients of pediatric peptic ulcer meeting the inclusion criteria were randomly divided into two groups equally.Besides conventional treatments,the control group was treated with esomeprazole,and the observa-tion group was treated with L -glutamine gung shimron acid sodium in combination with esomeprazole.After the course of treatment,the curative efficacy was compared after the eight -week follow -up.Before and after the treat-ment,T lymphocyte subpopulation (CD +4 ,CD +8 ,CD +4 /CD +8 )reflecting cellular immune function,intestinal flora and adverse reactions were compared.Results After the eight -week follow -up,the total effective rate of the observa-tion group was 96.7%,which was significantly higher than 86.7% of the control group (χ2 =3.93,P <0.05).After treatment,levels of CD +4 [(43.5 ±6.6)% vs (40.9 ±6.2)%],CD +4 /CD +8 [(1.72 ±0.38)vs (1.38 ±0.45)] were statistically higher and level of CD +8 [(26.2 ±3.7)% vs (30.1 ±5.0)%]was statistically lower in the obser-vation group in comparison with the control group (t =2.22,P <0.05;t =4.47,t =4.86,P <0.01).As to intestinal flora,the observation group had statistically higher concentration of lactobacillus [(7.5 ±1.3 )LonN /g feces vs (5.8 ±1.2)LonN /g feces],bifidobacterium[(8.3 ±1.1)LonN /g feces vs (6.6 ±1.4)LonN /g feces]in the feces in comparison with the control group after treatment (t =7.44,t =7.40,both P <0.05).During the treatment,there were no severe adverse reactions.Conclusion L -glutamine gung shimron acid sodium in combination with esome-prazole is effective for pediatric peptic ulcer,which can significantly increase curative efficacy,enhance cellular immune function and effectively regulate intestinal flora with minor adverse reactions.
