In a naturalistic pre-post design, samples of saliva were collected from the members of a professional chorale during an early rehearsal (n = 31), a late rehearsal (n = 34) and a public performance (n = 32) of Beethoven's Missa Solemnis. As measures of immune system response, mean levels of secretory immunoglobulin A increased significantly, as a proportion of whole protein, 150% during rehearsals and 240% during the performance. Cortisol concentrations decreased significantly an average of 30% during rehearsals and increased 37% during performance. As measured through performance perception rating scales, a group of emotions and other experiential states that singers associated with professional singing were highly predictive of changes in level of secretory immunoglobulin A during the performance condition, but the results for the rehearsal conditions were not significant. The best multiple regression model for performance level of immunoglobulin A (p < .0015) included seven emotional, cognitive, and evaluative variables generally associated with choral singing, including levels of mood before and during singing, stress, relaxation, feeling "high," detachment/engagement, and specific satisfaction with the immediate performance.

Formula-fed infants are more susceptible to infectious diseases because they lack the maternal immune factors transferred from breast milk, while their own immune system is still immature. As timely probiotic administration was suggested to promote immune system development in formula-fed infants, this study aimed at assessing the safety and the effects of a probiotic supplement (Bifidobacterium infantis R0033, Bifidobacterium bifidum R0071, and Lactobacillus helveticus R0052) on mucosal immune competence and digestive function in formula-fed infants. Healthy infants (3.5-6 months old) were randomised to receive either probiotic- (n=66) or placebo-supplemented (n=66) formula once a day for four weeks. In the probiotics group, faecal secretory immunoglobulin A (SIgA) levels remained similar between visit 2 (baseline; V2) and visit 3 (end-of-treatment; V3), but decreased in the placebo group. Changes in SIgA levels following treatment (log10ΔV3-V2 [95%CI]) between the probiotic and placebo groups were statistically significant (23 ng/dl [-57;102] and -137 ng/dl [-212;-62], respectively (P=0.0044; ANCOVA)). While log10ΔV3-V2 [95%CI] for salivary SIgA levels increased in both groups, this trend was more pronounced in the probiotics than in the placebo group with an increase of 123 ng/dl [9;236] and 37 ng/dL [-72;147], respectively (P=0.2829; ANCOVA). The weekly average number of stools/day was significantly higher in the probiotics group compared to placebo during the last week of treatment for the per protocol population. There was no difference in microbiota composition or anthropometric parameters between groups. No serious adverse event was reported, and all adverse events were mild and unrelated to the product or study. Our results show that formula-fed infants receiving probiotics maintained higher faecal SIgA levels at the end of the four-week treatment period, suggesting a positive effect of probiotics on SIgA production. This study demonstrates the safety of this probiotic formulation in infants. Formula-fed infants may benefit from probiotics supplementation to sustain the development of mucosal immunity.

Background: One of the problems with burn patients is the impairment of host immunity, which makes difficult to treat. In burns, immunoglobulinA has demonstrated to decrease. Immunoglobulin A is the main product of mucous immune system, which increases viral clearance and decreasesbacterial adhesion in the intestine. Probiotics consist of living microflora, which control the balance of lactobacilli and bifidobacteria in the intestine.Instead of producing organic component, increasing the acidity of intestine, mucin and bacteriocin, they also activate the intestinal immune systemand secretory immunoglobulin A (sIgA). The goal of this study was to propose that regular intake of probiotic might help to improve the mucousimmune system, especially sIgA in intestines in burn patients.Methods: An experimental, double-blind, controlled clinical trial was carried out in 33 burn patients. Those patients were divided into two groups.The first group was given daily probiotic and the second group was given only placebo for 10 days. The treatment began on the 4th day admission, andthen, the degree of sIgA was evaluated before treatment and day 14 from fecal specimen.Results: Significant differences between probiotic and control group were observed (p<0.0001). The degree of sIgA in the probiotic group increased61.25%, and in the control group, it decreased to 36.80%.Conclusion: The mucous immune system, especially sIgA, increases by probiotic intake.

The aim: To present data on the possibility of occurrence and active progression of generalized periodontitis in persons with secretory immunoglobulin A deficiency and possible methods of its correction. Мaterials and methods: Analytical elaboration of scientific and medical literature based on the immunological aspect of generalized periodontitis. Conclusions: The deficiency of secretory immunoglobulin A may occur in cases of primary or secondary insufficiency of the immune system. Selective IgA deficiency is an example of primary insufficiency of the immune system. Secondary immunodeficiency disorders is a clinical and immunological syndrome that develops against the background of a previously normally functioning immune system, characterized by a steady decrease in quantitative or functional indicators of specific or(and) nonspecific factors of immunoresistance. Insufficient awareness of dentists about certain aspects of the etiology and pathogenesis of generalized periodontitis leads to deterioration of treatment results.

Secretory Immunoglobulin

AbstractAntibodies are key elements of protective immunity. In the mucosal immune system in particular, secretory immunoglobulin A (SIgA), the most abundantly produced antibody isotype, protects against infections, shields the mucosal surface from toxins and environmental factors, and regulates immune homeostasis and a peaceful coexistence with our microbiota. However, the dark side of IgA biology promotes the formation of immune complexes and provokes pathologies, e.g., IgA nephropathy (IgAN). The precise mechanisms of how IgA responses become deregulated and pathogenic in IgAN remain unresolved. Yet, as the field of microbiota research moved into the limelight, our basic understanding of IgA biology has been taking a leap forward. Here, we discuss the structure of IgA, the anatomical and cellular foundation of mucosal antibody responses, and current concepts of how we envision the interaction of SIgA and the microbiota. We center on key concepts in the field while taking account of both historic findings and exciting new observations to provide a comprehensive groundwork for the understanding of IgA biology from the perspective of a mucosal immunologist.
