Rhinitis

The objective of this study is to test the hypothesis that over-the-counter amino acid supplement 5HTP (isolated from the plant Griffonia Simplifolia) reduces human allergic lung responses and consequently improves lung function. The primary outcome is the change in FEV1. We anticipate the 5HTP at the proposed doses will improve lung function as in preclinical studies that used clinically relevant 5HTP. Secondary outcomes will be blood eosinophil counts and reduced symptoms for anxiety/depression, as seen in changes in the anxiety-depression scores from questionnaires (CES-DC \& SCARED). The results from these studies have the transformative potential to influence approaches to improve lung function and asthma-associated anxiety/depression. * Aim 1: Test that 5HTP improves lung function in children with allergic asthma * Aim 2: Test that 5HTP reduces eosinophil numbers in the blood and nasal fluid of patients with asthma from Aim 1 * Aim 3: Test that 5HTP decreases lung inflammation, increases cortisol and prolactin without altering systemic plasma concentrations of 5HTP, serotonin, 5-hydroxyindoleacetic acid (5-HIAA), and dopamine

This is a trial to evaluate the safety and efficacy of SHR-1819 injection in the treatment of patients with seasonal allergic rhinitis.

This is a follow-up study of a randomised clinical trial, called TEMPO (a double-blind randomized clinical trial investigating infant formula and human breast milk consumption), in which infants participated in their first year of life. The investigators like to know if these children develop allergies or infections in childhood and whether their feeding pattern in infancy plays a role.

The aim of the present study is to establish a modified minimally invasive surgical technique for sinus floor augmentation with a residual bone height of 3-6mm. Hypothesis: The investigators expect that the present surgical technique allows to achieve an adequate implant bed of at least 10mm height after a healing period of 3-5 months. Further the modification of the technique enables a reduced patient stress level.

The trial aims to evaluate efficacy of the house dust mite (HDM) SLIT-tablet compared to placebo in Chinese participants aged 12-65 with HDM allergic rhinitis/rhinoconjunctivitis with or without asthma. Efficacy will be assessed based on the total combined rhinitis score during the last 4 weeks of treatment. The trial is a randomised, double-blind, parallel-group, placebo-controlled, multi-site, phase III trial conducted in China. The treatment period will be 24-28 weeks.

The present study is a randomized, double-blind, placebo-controlled, comparative study. 176 individuals will be screened, and considering a screening failure rate of 15 percent approximately 150 will be randomized in a ratio of 1:1 to receive either IP or placebo and will be assigned a unique randomization code. Each group will have at least 60 completed participants after accounting for a dropout/withdrawal rate of 20percent. The intervention duration for all the study participants is 7 days

The main purpose of this study is to evaluate the efficacy and safety of lebrikizumab in adult participants with perennial allergic rhinitis. Participants can expect study participation to last up to 29.5 months.

To further evaluate the efficacy and safety of Antiwei granule in the treatment of common cold (wind-cold syndrome)

Allergic rhinitis (AR) is an immunoglobulin E-mediated inflammatory disease1 caused by hypersensitivity of the immune system to an allergen, affecting 100 million people in Europe 2and 400 million of the global population.The etiology of AR is multifactorial, resulting primarily from genetic predisposition, immunological response, and environmental pollutants.AR traditionally has been classified as seasonal (SAR) or perennial (PAR) depending on the causes and duration of symptoms. Some patients with AR prefer complementary and alternative medicine for their symptoms, with nearly 20% receiving acupuncture. According to the updated practice parameter of rhinitis in 2020, the use of acupuncture for the treatment of AR was not recommended due to a lack of well-controlled studies. The sphenopalatine ganglion (SPG), located under a thin (1-2 mm) layer of mucosa in the pterygopalatine fossa, consists of sensory fibers that innervate the nasopharynx, nasal cavity, and palate.Several studies have reported the benefit of SPG stimulation in chronic cluster headache and acute ischaemic stroke. Compared with traditional acupoints selected on basis of traditional meridian theory, acupuncture at SPG(inserting a needle through SPG acupoint (near ST7, Xiaguan) to reach and directly stimulate the SPG) may help patients ameliorate nasal symptoms immediately and improve quality of life by increasing sympathetic nerve excitability, but the evidence is inconclusive. We have designed this three-armed, randomized trial to investigate the efficacy and safety of acupuncture at SPG for the treatment of SAR. We hypothesize that acupuncture at SPG plus rescue medication is superior to sham acupuncture plus RM and RM alone in the treatment of SAR.

The purpose of the study is to investigate the impact of co-morbidities, history, and allergen tests on the outcome of allergen provocation tests. Subjects are children aged 0-18 years old investigated for allergy to foods or antibiotics. Data entered in the database are demographics, co-morbidities, symptoms, SPT, specific IgE and details of the allergen provocations.
