Allergic disorders are very common in the pediatric age group. While the exact etiology is unclear, evidence is mounting to incriminate environmental factors and an aberrant gut microbiota with a shift of the Th1/Th2 balance towards a Th2 response. Probiotics have been shown to modulate the immune system back to a Th1 response. Several in vitro studies suggest a role for probiotics in treating allergic disorders. Human trials demonstrate a limited benefit for the use of probiotics in atopic dermatitis in a preventive as well as a therapeutic capacity. Data supporting their use in allergic rhinitis are less robust. Currently, there is no role for probiotic therapy in the treatment of bronchial asthma. Future studies will be critical in determining the exact role of probiotics in allergic disorders.
过敏症在儿科中非常常见。虽然确切的病因尚不清楚,但越来越多的证据表明环境因素和肠道菌群异常与 Th1/Th2 平衡向 Th2 反应转移有关。益生菌已被证明可以使免疫系统恢复到 Th1 反应。几项体外研究表明益生菌在治疗过敏症方面具有一定作用。人体试验表明,益生菌在预防和治疗特应性皮炎方面具有一定的益处。支持其在过敏性鼻炎中应用的数据则不那么有力。目前,益生菌疗法在治疗支气管哮喘方面没有作用。未来的研究对于确定益生菌在过敏症中的确切作用至关重要。
