- CONCLUSION: Subjects with self-reported nasal symptoms following consumption of red wine may respond with less nasal blockage to a wine produced with ecological methods than to wine not labelled as ecologically produced. OBJECTIVE: To compare nasal symptoms following intake of three different wines--one that was ecologically produced and two that were traditionally produced. SUBJECTS AND METHODS: Individuals with self-reported nasal symptoms following consumption of red wine were subjected to controlled intake of three different wines in a double-blinded, randomized, and crossover design. Nasal symptoms and peak nasal inspiratory flow (PNIF) were monitored before and 15, 30, 45, and 60 min following intake of wine. RESULTS: All wines produced nasal symptoms, notably nasal blockage. While blockage scores did not differ between the two non-ecological wines, the ecological wine was associated with significantly lower blockage scores, as compared with both the other wines.

- Background: Topical probiotics have been suggested as a treatment option for allergic rhinitis, as they may skew the immune response towards a beneficial type-1 non-allergic profile. So far observations in man have exclusively involved oral intake. The aim of this study was to examine whether a topical/nasal administration of a probiotic assemblage (PA) affects quality of life, symptoms and signs of allergic rhinitis in a nasal allergen challenge (NAC) model.Methods: In a placebo-controlled and crossover design, 24 patients with seasonal allergic rhinitis were randomised to topical/nasal administration with a PA of Lactobacillus rhamnosus SP1, Lactobacillus paracasei 101/37 and Lactococcus lactis L1A or placebo for 3 weeks. Participants and investigators were blind to treatment allocation. The last week of each treatment period was combined with a NAC series. Efficacy variables were "Mini-Rhinoconjunctivitis Quality of Life Questionnaire" (Mini-RQLQ), "Total Nasal Symptom Score" (TNSS), "Peak Nasal Inspiratory Flow" (PNIF) and "Fractional Exhaled Nitric Oxide" (FeNO). In addition, to assess whether or not the PA produced any pro-inflammatory effect per se, soluble analytes were monitored in nasal lavage fluids. Finally, bacterial cultures, sampled using swabs from the middle nasal meatus, were assessed for the presence of the PA by MALDI-TOF analysis.Results: Administration of the PA did not produce any nasal symptoms (cf. placebo). An innate immune response was discerned within the PA run (cf. baseline), but no change in nasal lavage fluid levels of cytokines/mediators was observed cf. placebo except for IL-17/IL-17A (a minor increase in the PA run). Administration of the PA did neither affect Mini-RQLQ, TNSS, PNIF nor FeNO. No evidence of persistent colonization was observed.Conclusions: Topical/nasal administration of a PA comprising Lactobacillus rhamnosus SP1, Lactobacillus paracasei 101/37 and Lactococcus lactis L1A, while likely evoking a minor innate immune response yet being safe, does not affect quality of life, symptoms or signs of allergic rhinitis.

- Background: Chronic or recurrent rhinosinusitis without polyps (CRSsNP) is characterized by a persistent inflammation of the sinonasal mucosa. The underlying cause is unclear but increasing interest has been directed toward changes in the sinonasal microbiome as a potential driver. Methods: Twenty-two patients diagnosed with CRSsNP were treated with antibiotics for 13 days, followed by 5 consecutive days of nasal microbiome transplants from healthy donors. Outcome measures were 22-item Sino-Nasal Outcome Test (SNOT-22) questionnaire, total nasal symptom score (TNSS), endoscopic grading, 16S ribosomal RNA (rRNA) next generation sequencing (microbiome analysis), and nasal lavage fluid analysis of inflammatory cytokines. Patients were examined at the start of the study and after antibiotic treatment as well as 10 days and 3 months after the transplant series. Results: At the end of the study, patients reported significantly reduced SNOT-22 scores and microbiome analysis showed significantly increased abundance and diversity. No significant change was observed for TNSS or endoscopic scoring. Conclusion: Nasal microbiome transplants obtained from healthy individuals and administered as nasal lavages to patients with CRSsNP are feasible. The patients reported significant and lasting reduction of symptoms and these findings were associated with a lasting increase in abundance and diversity of the local bacterial flora. The observations, which need to be confirmed by randomized controlled trials, may constitute a new treatment avenue for these difficult to treat patients where antibiotics only provide short lasting symptom control.
