In current conditions, traditional antiallergic therapy for atopic dermatitis does not always help to achieve timely remission, so the development of effective therapy methods is a very topical task. The promising direction of probiotics in combination with prebiot-ics, including the original mono-strain synbiotic Lactobacillus rhamnosus LGG® at optimal high concentration of 4 х 109 CFU and prebiotic fructooligosaccharides 800 mg is drawing attention. This article presents data in a clinical case format. This article presents its own data in a clinical case format. The clinical case 1 showed that administration of synbiotic in 1 sachet 1 time per day for 14 days in the composition therapeutic diet during the period of complex antiallergic therapy to a 5-month-old child with a moderate course of atopic dermatitis resulted in a pronounced positive dynamics and achievement of remission on the 10th day after the treatment start against normalization of stool. Prior to this, the child had received only antiallergic therapy, which led to improvement of the skin process, but full clinical remission could not be achieved. Clinical case 2 showed the effectiveness of synbiotic in the composition therapeutic diet during the period of comprehensive antiallergic therapy in a 10-month-old child with a mild course of atopic dermatitis. From day 2 of treatment there was a significant positive dynamics in the skin process. On day 12, remission was achieved: relief of acute inflammatory elements on the face and at the elbows on the background of increased lactobaciUus content from 104 to 106 CFU/g of feces and bifidobacteria from 107 to 109 CFU/g of feces. Clinical case 3 demonstrates the efficacy of synbiotic in 2 sachets once a day for 14 days in a 9-year-old child with atopic dermatitis of moderate severity with a continuously relapsing course. From the 4th day of the beginning of the complex therapy positive dynamics in the skin process was noted, on the 14th day partial remission was achieved: erythematous elements on the back and extremities were eliminated, signs of hyperemia, infiltration and scratching disappeared against the background of stool normalization. Signs of dryness and slight lichenification persisted. Thus, these clinical examples demonstrate a high efficacy of synbiotic treatment in the complex antiallergic therapy of atopic dermatitis in children.
