ABSTRACT
Food allergies are common, affecting a sizable portion of children and adults in the Western world. In recent years, a promising treatment known as allergen immunotherapy (AIT) has emerged. This technique aims to address the fundamental immune system dysfunction that underlies food allergies. The study’s objective was to evaluate the safety of combining probiotics with AIT, compared to placebo in treating patients with food allergies. A comprehensive literature search in several databases was conducted. All included studies were randomized controlled trials(RCTs). Meta-analyses were performed using R software. Statistical tests to assess safety outcomes and risk of bias were used. After reviewing 519 studies, three studies were included in the systematic review and meta-analysis, involving a total of 258 patients (141 in the probiotics group, 144 in the placebo group). The evaluation of the safety profile of the integrated probiotic therapy revealed an overall favorable outcome, with no significant differences in adverse events compared to placebo for most organ systems examined. However, a potential increase in oral adverse effects was observed in the probiotics group (RR = 1.7573, 95% CI: 0.3941 to 7.8359), although this result did not reach statistical significance. The combination of probiotics and allergen-specific immunotherapy appears to be generally safe and shows promise as a valuable treatment approach.
