Abstract

Background

ß-glucans isolated from natural sources have demonstrated pluripotent immunomodulatory potential, making them a promising supportive treatment for the management of recurrent respiratory infections (RRIs) in children. This study aimed to evaluate the effects of a pleuran-based supplement (ß-glucan isolated from Pleurotus ostreatus in combination with vitamin D and zinc) on mucosal immunity –through modulating salivary secretory immunoglobulin A (sIgA) levels –in children with RRIs.

Methods

This monocentric, prospective, open-label pilot study investigated the effect of an orally administered pleuran/vitamin D/zinc supplement (1–2 chewable tablets daily depending on body weight) on the dynamics of sIgA secretion measured in saliva samples collected at three timepoints: at baseline and after 4–6 and 8–10 days.

Results

This study included 49 children aged 6-11 years (mean age: 8.2 ± 1.6 years) with a history of one or more of the following conditions in the inclusion criteria: RRIs, allergy, and asthma. After 8–10 days with daily administration of the chewable pleuran/vitamin D/zinc supplement, children exhibited a statistically significant increase in salivary sIgA concentrations compared with baseline (227 ± 211 µg/mL; P = 0.045). No adverse events were observed during the course of the study in relation to the administration of pleuran-based supplement.

Conclusions

We demonstrated the beneficial effects of the short-term administration of a pleuran-based chewable supplement on mucosal immunity through increasing salivatory sIgA levels. This study confirms the favourable safety profile of this pleuran/vitamin D/zinc combination, which could be beneficial for children with acute or recurrent respiratory infections, including children with allergies and/or asthma. Moreover, the significant increases in salivary sIgA concentrations that were observed after a few days of supplementation support the use of pleuran in not only the prevention but also the treatment of acute respiratory infections.

期刊介绍： We also encourage the submission of manuscripts presenting preclinical and very preliminary research that may stimulate further investigation of potentially relevant findings, as well as in-depth review articles on specific therapies or disease states, and applied health delivery or pharmacoeconomics. CTR encourages and supports the submission of manuscripts describing: • Interventions designed to understand or improve human health, disease treatment or disease prevention; • Studies that focus on problems that are uncommon in resource-rich countries; • Research that is "under-published" because of limited access to monetary resources such as English language support and Open Access fees (CTR offers deeply discounted English language editing); • Republication of articles previously published in non-English journals (eg, evidence-based guidelines) which could be useful if translated into English; • Preclinical and clinical product development studies that are not pursued for further investigation based upon early phase results.
