Abstract
Background: Early phase clinical research provided initial support for the use of a multispecies probiotic supplement to improve quality of life (QoL) in adults with seasonal allergic rhinitis (AR) and reduce the use of AR symptom relieving medication. This study aimed to confirm these early phase findings in a double-blind randomized placebo-controlled trial. Methods: Individuals, aged 18-65 years, with a minimum 2-year history of AR, moderate-to-severe AR symptoms, and a positive radio-allergosorbent test to Bermuda (Couch) Grass were randomized to receive either a multispecies probiotic supplement (total colony-forming units 4 × 109/day) or placebo twice daily for 8 weeks. A mini-rhinoconjunctivitis quality of life questionnaire (mRQLQ) scale was administered at screening, days 0, 28, and 56. The proportion of participants with a >0.7 improvement in mRQLQ was the primary outcome. Participants also completed a daily symptom and medication diary during the supplementation period. Results: There were 165 participants randomized, with 142 included in the primary outcome analysis. The percentage of participants meeting the threshold for a clinically meaningful reduction in the mRQLQ from days 0 to 56 was not significantly different between groups (61% vs. 62%, p = 0.90). However, 76 participants had a clinically meaningful improvement in QoL (decrease in mRQLQ >0.7) prior to the start of supplementation (screening to day 0). Conclusion: Changes in self-reported QoL and other disease severity metrics between screening and the start of supplementation limited the ability to discern an effect of supplementation and highlight the need for adaptive clinical trial designs in allergy research. Clinical Trial Registration: The trial was registered with the Australia and New Zealand Clinical Trials Registry (ACTRN12619001319167).

Abstract
Probiotic intervention may have a promising role in the prevention of AR, in preventing allergic diseases including AR. Probiotics can exert beneficial effects on the host through distinct cellular and molecular pathways, these mechanisms of action may vary from one kind of probiotic to another for the same immune response and may be regulated by a combination of several events. Material and methods- Research site-Tertiary Care Government Hospital and Medical College in a major metropolitan city.TYPE OF STUDY-Prospective comparative Study.No. of Subjects -100 cases.Study Duration-Duration for collection of data-24 months.Sample size -100 patientsData Collection:Was collected from data of case proforma of all patients.Mode of Selection -Patients presenting in Out Patient Department (OPD)and In PatientDepartment(IPD) who meet the inclusion criteria and who consent to be a part of the study.Results-Significant difference was found in 12 weeks of treatment among group A and group B. Mild symptoms were seen more after 12 weeks in group B while severity of symptom reduction was less in group A as compared to group B in 12 weeks of treatment.Conclusion Probiotic intervention may have a promising role in the prevention of AR, in preventing allergic diseases including AR.Probiotics can exert beneficial effects on the host through distinct cellular and molecular pathways, these mechanisms of action may vary from one kind of probiotic to another for the same immune response and may be regulated by a combination of several events. Thus making probiotics' mechanism of action a challenging, complex, and fertile area for investigation. Probiotics appear to prevent allergy recurrences, alleviate the severity of symptoms and improve the quality of life of patients with allergic rhinitis.

Abstract
OBJECTIVE This meta-analysis aimed to evaluate the effectiveness and safety of probiotics for allergic rhinitis (AR) management in children. METHODS In total, 6 databases were searched, and 26 randomized controlled trials that compared the effects of probiotics with those not using probiotics in pediatric AR were included. Methodological quality was assessed using the Cochrane risk-of-bias tool. Data for relevant endpoints were extracted and analyzed. RESULTS Our meta-analysis of the effectiveness of probiotics for pediatric AR showed that probiotics improved the remission rate of nasal symptoms (risk ratio (RR) 1.21, 95% confidence interval (CI) 1.04 to 1.40; P = 0.01), reduced the Total Nasal Symptoms Scores (TNSS) (weighted mean difference (WMD) -2.58, 95% CI -2.77 to -2.39; P < 0.00001) and the total scores of Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) (for frequency of symptoms: WMD -9.51, 95% CI -10.34 to -8.69; P < 0.00001; and for level of bother: WMD -9.27, 95% CI -10.13 to -8.41; P < 0.00001). Furthermore, they reduced the serum levels of interleukin-4 (IL-4) (WMD -13.86 ng/L, 95% CI -15.92 to -11.81; P < 0.00001), IL-6 (WMD -13.70 pg/mL, 95% CI -16.34 to -11.07; P < 0.00001), and IL-17(WMD -5.41 pg/mL, 95% CI -7.29 to -3.52; P < 0.00001), and significantly elevated the serum levels of interferon-γ (WMD 9.08 ng/L, 95% CI 8.10 to 10.06; P < 0.00001) and IL-10 (WMD 7.82 pg/mL, 95% CI 5.01 to 10.63; P < 0.00001). Probiotics also reduced the duration of cetirizine use in pediatric AR (WMD -2.88 days, 95% CI -4.50 to -1.26; P < 0.0005). No obvious adverse reactions were found to be related to probiotic treatment. CONCLUSIONS This meta-analysis indicated that probiotic therapy can partially improve pediatric AR outcomes, assisted by modulating immune balance and reducing anti-allergic medication use, without obvious adverse reactions.

Probiotics function and modulation of the immune system in allergic diseases. Allergol Immunopathol (Madr) 2020; 48:771-788.

Abstract
Allergic diseases have been a global problem over the past few decades. The effect of allergic diseases on healthcare systems and society is generally remarkable and is considered as one of the most common causes of chronic and hospitalized disease. The functional ability of probiotics to modulate the innate/acquired immune system leads to the initiation of mucosal/systemic immune responses. Gut microbiota plays a beneficial role in food digestion, development of the immune system, control/growth of the intestinal epithelial cells and their differentiation. Prescribing probiotics causes a significant change in the intestinal microflora and modulates cytokine secretion, including networks of genes, TLRs, signaling molecules and increased intestinal IgA responses. The modulation of the Th1/Th2 balance is done by probiotics, which suppress Th2 responses with shifts to Th1 and thereby prevent allergies. In general, probiotics are associated with a decrease in inflammation by increasing butyrate production and induction of tolerance with an increase in the ratio of cytokines such as IL-4, IL-10/IFN-γ, Treg/TGF-β, reducing serum eosinophil levels and the expression of metalloproteinase-9 which contribute to the improvement of the allergic disease's symptoms. Finally, it can be said that the therapeutic approach to immunotherapy and the reduction of the risk of side effects in the treatment of allergic diseases is the first priority of treatment and the final approach that completes the first priority in maintaining the condition and sustainability of the tolerance along with the recovery of the individual.

Abstract
INTRODUCTION Unique gut microbial colonisation patterns are associated with the onset of allergic disease in infants; however, there is insufficient evidence to determine if aberrant microbial composition patterns persist in adult allergic rhinitis (AR) sufferers. OBJECTIVE To compare the gut microbiome composition between adult AR sufferers and controls. METHODS Gut microbial composition in stool samples was compared between 57 adult AR sufferers (39.06 ± 13.29 years) and 23 controls (CG; 36.55 ± 10.51 years) via next-generation sequencing of the V3-V4 hypervariable regions of the 16S rRNA gene. Taxonomic classification and identity assignment was performed using a reference-based approach with the NCBI database of 16S rRNA gene sequences. RESULTS Species richness determined via the Shannon index was significantly reduced in the AR cohort compared to the CG (4.35 ± 0.59 in AR vs. 4.65 ± 0.55 in CG, p = 0.037); trends for reductions in operational taxonomic unit (OTU) counts, inverse Simpson, and CHAO1 diversity indices were also noted. Bacteroidetes (p = 0.014) was significantly more abundant in the AR group than in the CG. In contrast, the Firmicutes phylum was significantly less abundant in the AR group than in the CG (p = 0.006). An increased abundance of Parabacteroides (p = 0.008) and a reduced abundance of Oxalobacter (p = 0.001) and Clostridiales (p = 0.005) were also observed in the AR cohort compared to the CG. CONCLUSION Adult AR sufferers have a distinct gut microbiome profile, marked by a reduced microbial diversity and altered abundance of certain microbes compared to controls. The results of this study provide evidence that unique gut microbial patterns occur in AR sufferers in adulthood and warrant further examination in the form of mechanistic studies.

Abstract
Interaction between a healthy microbiome and the immune system leads to body homeostasis, as dysbiosis in microbiome content and loss of diversity may result in disease development. Due to the ability of probiotics to help and modify microbiome constitution, probiotics are now widely used for the prevention and treatment of different gastrointestinal, inflammatory, and, more recently, respiratory diseases. In this regard, chronic respiratory diseases including chronic obstructive pulmonary disease (COPD), asthma and allergic rhinitis are among the most common and complicated respiratory diseases with no specific treatment until now. Accordingly, many studies have evaluated the therapeutic efficacy of probiotic administration (mostly via the oral route and much lesser nasal route) on chronic respiratory diseases. We tried to summarise and evaluate these studies to give a perspective of probiotic therapy via both the oral and nasal routes for respiratory infections (in general) and chronic respiratory diseases (specifically). We finally concluded that probiotics might be useful for allergic diseases. For asthmatic patients, probiotics can modulate serum cytokines and IgE and decrease eosinophilia, but with no significant reduction in clinical symptoms. For COPD, only limited studies were found with uncertain clinical efficacy. For intranasal administration, although some studies propose more efficiency than the oral route, more clinical evaluations are warranted.

Digital Immune Gene Expression Profiling Discriminates Allergic Rhinitis Responders from Non-Responders to Probiotic Supplementation. Genes (Basel) 2019; 10:genes10110889.

Abstract
Probiotic supplementation for eight weeks with a multi-strain probiotic by individuals with allergic rhinitis (AR) reduced overall symptom severity, the frequency of medication use and improved quality of life. The purported mechanism of action is modulation of the immune system. This analysis examined changes in systemic and mucosal immune gene expression in a subgroup of individuals, classified as either responders or non-responders based on improvement of AR symptoms in response to the probiotic supplement. Based on established criteria of a beneficial change in the mini-rhinoconjunctivitis quality of life questionnaire (mRQLQ), individuals with AR were classified as either responders or non-responders. Systemic and mucosal immune gene expression was assessed using nCounter PanCancer Immune Profiling (Nanostring Technologies, Seattle, WA, USA) kit on blood samples and a nasal lysate. There were 414 immune genes in the blood and 312 immune genes in the mucosal samples expressed above the limit of detection. Unsupervised hierarchical clustering of immune genes separated responders from non-responders in blood and mucosal samples at baseline and after supplementation, with key T-cell immune genes differentially expressed between the groups. Striking differences in biological processes and pathways were evident in nasal mucosa but not blood in responders compared to non-responders. These findings support the use of network approaches to understand probiotic-induced changes to the immune system.

Abstract
Objectives: To evaluate the effect of a probiotic supplement containing two genera and five species of bacteria versus placebo on the quality of life (QoL) in female university students with intestinal constipation (IC). Design: A randomized, double-blind placebo-controlled study was conducted on female university students in a single study center. Settings/Location: Two phases of interventions were carried out, the pilot and main study. All participants were female students of Federal University of Mato Grosso, Brazil. Subjects: Female students whose ages ranged from 20 to 40 years and self-reported to be suffering from IC based on a questionnaire containing Rome III criteria were included. Interventions: Interventions occurred during a period of 30 days in the pilot phase (n = 32) and 15 days in the main study phase (n = 63). The subjects were numbered and randomly divided into experimental probiotic and placebo control groups. Therefore, neither the participants nor the researchers were aware of the allocations of the treatment groups. Outcome measures: The sociodemographic, Rome III, Patient Assessment of Constipation Quality of Life (PAC-QoL) and International Physical Activity questionnaires, and anthropometric measures were utilized. The relative risk (RR) treatment effect, absolute risk reduction (ARR), RR reduction, number needed to treat (NNT), and odds ratio were calculated. Results: Improvement in the QoL (ARR = 14% and p < 0.01) and satisfaction (ARR = 44% and p < 0.01) according to the PAC-QoL questionnaire was observed in the experimental group compared with the control group. For probiotic supplementation, an NNT = 7 was obtained. This implies that for every seven constipated women treated, a worsening in the QoL is prevented in one. An NNT = 1 was obtained concerning satisfaction in the same group of women with respect to the treatment. No clinically significant observations related to the safety of the product were reported. The authors did not detect the effect of exercise intensity on the QoL of participants. Conclusion: The probiotic supplementation had a positive impact on the QoL of constipated female university students.

Bovine colostrum-driven modulation of intestinal epithelial cells for increased commensal colonisation. Appl Microbiol Biotechnol 2019; 103:2745-2758.

Abstract
Nutritional intake may influence the intestinal epithelial glycome and in turn the available attachment sites for bacteria. In this study, we tested the hypothesis that bovine colostrum may influence the intestinal cell surface and in turn the attachment of commensal organisms. Human HT-29 intestinal cells were exposed to a bovine colostrum fraction (BCF) rich in free oligosaccharides. The adherence of several commensal bacteria, comprising mainly bifidobacteria, to the intestinal cells was significantly enhanced (up to 52-fold) for all strains tested which spanned species that are found across the human lifespan. Importantly, the changes to the HT-29 cell surface did not support enhanced adhesion of the enteric pathogens tested. The gene expression profile of the HT-29 cells following treatment with the BCF was evaluated by microarray analysis. Many so called "glyco-genes" (glycosyltransferases and genes involved in the complex biosynthetic pathways of glycans) were found to be differentially regulated suggesting modulation of the enzymatic addition of sugars to glycoconjugate proteins. The microarray data was further validated by means of real-time PCR. The current findings provide an insight into how commensal microorganisms colonise the human gut and highlight the potential of colostrum and milk components as functional ingredients that can potentially increase commensal numbers in individuals with lower counts of health-promoting bacteria.
