This investigation has been performed to show the efficacy of Lactobacillus rhamnosus GG (LGG) together with milk-free diet in patients with cow’s milk protein allergy (CMPA). This multicentre prospective investigation has been performed in 0–12 months of age children diagnosed as CMPA clinically and biochemically. Patients have been randomly divided in to two groups. İnfants in probiotic group were received with cow’s milk protein free diet and per oral (p.o.) daily 1X109 CFU LGG and in placebo group with milk-free diet and placebo. Mothers of all breast-fed patients have been put on milk-free diet and all patients fed with formula, offered to extensively hydrolysed formula. Symptoms like diarrhoea, vomiting, mucousy or bloody stool, abdominal pain or distension, constipation, dermatitis and restiveness were recorded at the beginning and weekly during the receiving dietary by the investigator. One-hundred infants diagnosed CMPA were included in this double-blind placebo controlled study. Forty-eight infants placed in probiotic group and 52 in placebo group. After 4 weeks of receiving dietary, infants in probiotic group have showed statistically significant improvement in symptoms of bloody stool, diarrhoea, restiveness and abdominal distension (p ≤ 0.001). Whilst statistically significant improvement was also observed in symptoms of mucousy stool (p = 0.038) and vomiting (p = 0.034), no significant improvement were observed in abdominal pain (p = 0.325), constipation (p = 0.917) and dermatitis (p = 0.071). In this study we observed significant improvement in symptoms of infants diagnosed CMPA receiving dietary LGG with cow’s milk-free diet.
