Bencycloquidium bromide nasal spray is effective and safe for persistent allergic rhinitis: a phase III, multicenter, randomized, double-blinded, placebo-controlled clinical trial

AbstractPurposeTo investigate the efficacy and safety of bencycloquidium bromide nasal spray (BCQB) in patients with persistent allergic rhinitis (PAR).MethodsWe enrolled 720 patients from 15 hospitals across China and randomly assigned them into BCQB group or placebo group (90  μg per nostril qid) to receive a 4-week treatment. Visual analog scale (VAS) for rhinorrhea, sneezing, nasal congestion, itching and overall symptoms were recorded by patients every day. Anterior rhinoscopy scoring was completed by doctors on every visit. Adverse events were recorded in detail.ResultsA total of 354 and 351 patients were included in BCQB group and in placebo group. Baseline information was comparable. At the end of the trial, the decrease of VAS for rhinorrhea from baseline was 4.83  ± 2.35 and 2.46 ± 2.34 in BCQB group and placebo group, respectively (P

Conclusion: Existing evidence shows that TFM is safe and effective for AR. Due to the universal low quality of the eligible trials and low evidence level, we should draw our conclusions with caution. Therefore, clinical researchers should carry out more large-sample, multicentre, high-quality randomized controlled clinical trials in the future to verify the clinical efficacy of TFM in treating AR.

ConclusionThe prevalence of SDB is high in children living in both settings but associated risk factors may vary. Children residing in rural areas should also be screened for sleep-disordered breathing during routine health visits.

Authors: Ehret M, Bourcier T, Domis N, Gherasim A, Speeg-Schatz C, de Blay F Abstract Allergic conjunctivitis affects 15 to 20% of the general population. It is currently evaluated by the Conjunctival Provocation Test (CPT), which is considered as the gold standard. In the investigation of allergic rhinitis and asthma, environmental exposure chambers (EEC) are increasingly utilised. For allergic conjunctivitis, EEC might be a valid alternative to the CPT. However, evaluation of the allergen response in individual provocation tests or in EECs is still in discussion due to the multiplicity of symptom scores. Indeed, ...

CONCLUSIONS: Increased TRPV4 expression occurred in epithelial cells harvested from patients with AR and epithelial cells stimulated by Th2 cytokines. Decreased junctional protein expression in epithelial cells after the stimulation by house dust mite allergen with TRPV4 agonist indicates a possible role of TRPV4 in the pathogenesis of allergen-induced epithelial barrier disruption in AR.

In this study, the effects of a novel pendrin inhibitor, YS-01, were investigated in an LPS-induced acute lung injury (ALI) mice model, and the mechanism underlying the effect of YS-01 was examined.Methods: Lipopolysaccharide (LPS, 10 mg/kg) was intranasally instilled in wild type (WT) and pendrin-null mice. YS-01 (10 mg/kg) was administered intra-peritoneally before or after LPS inhalation. Lung injury parameters were assessed in the lung tissue and bronchoalveolar lavage fluid (BALF). Pendrin levels in the BALF of 41 patients with acute respiratory distress syndrome (ARDS) due to pneumonia and 25 control (solitary pulmon...

ConclusionThe most common otolaryngologic symptoms of COVID-19 infection are known as sore throat, smell and/or taste disturbances. However, our study showed that these patients can be seen with different symptoms in otological or laryngeal areas. Therefore, a more careful evaluation should be made in terms of otolaryngologic symptoms when COVID 19 infection is suspected.

Biologics have revolutionized medical therapy in the past 2 decades. Allergic Diseases have benefited from this revolution as a variety of biologics have impacted all categories of allergic diseases. Anticytokines directed at type 2 immunity has helped in the treatment of all allergic conditions covered in this issue ranging from Allergic Rhinitis to Asthma to Atopic Dermatitis to Food Allergy and others. Obviously, the ravages of COVID-19 on processes involved in biologic treatment are a consideration, but current thinking suggests such therapies should not be affected by the pandemic.
