Clinical efficacy and tolerability for allergen specific immunotherapy (AIT) with Itulazax (birch pollen extract tablet) is well established. Allergen challenges are used by clinicians to confirm correct diagnosis and by researchers to evaluate the efficacy of different interventions, eg. AIT. The challenge is performed by using a specific controlled administration schedule of an allergen product in the shock organ (nose, eye, or airway) and then monitor the result. Nasal Allergen Challenge (NAC) is the most common allergen challenge used. Aquagen SQ (birch pollen extract) has since decades been golden standard for this purpose, but production of this product ended 2019. Clinicians as well as researchers are now in need for an alternative product. To evaluate a new method for NAC would be of value from a clinical- and research perspective. From a Nordic perspective a NAC study with dissolved Itulazax would be of special interest since birch allergy is a dominant allergen in the region. In a recently published article it was shown that dissolved Grazax and Aquagen Phleum pratense gave comparable result used in grass allergic patients. Therefore, it seems reasonable to assume that the same method could be used with dissolved Itulazax. The aim of this clinical trial is to evaluate the feasibility of nasal allergen challenge tests with dissolved Itulazax tablets. The main benefit of this proposal is that the allergen composition of the provocation test product is the same as the final product to be treated with. This is likely to increase the treatment motivation of the patient. In addition, the dissolving process is easier for the physician compared to the dissolving of the previously used Aquagen.
Allergic rhinitis (AR) affects large population worldwide, the most commonly used medication include anti-histamine, nasal spray and anti-LTRAs inhibitors (leukotriene receptor antagonists), Even after those first-line treatment, there is still a large number of patient (~20%) are not well/adequately controlled. Anti-IgE antibody has been approved to treat moderate to severe AR by PMDA/Japan in 2020, demonstrating the efficacy of IgE blockade in the treatment of allergic rhinitis. The current study presents a novel anti-IgE antibody (LP-003) with higher affinity to IgE, stronger efficacy and longer half-life.
Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease of the nasal mucosa mainly mediated by immunoglobulin E after exposure to allergens in atopic individuals. The typical symptoms of AR are paroxysmal sneezing, watery rhinorrhea, itching, and nasal congestion, which may be accompanied by ocular symptoms, including eye itching, tearing, redness, and burning sensation, which are more common in patients with hay fever allergies. Bronchial asthma is associated with bronchial asthma in 40% of patients with AR, suggesting a comorbid feature of allergic disease.
Allergy is a public health problem as more than 20% of western society is affected by it. Symptomatic treatment of allergy suffices with less severe allergy. Patients with more severe allergy should be treated with allergen immunotherapy (AIT). Present options of AIT are efficient but of long duration, associated with side effects and require much time from the patient. With Intralymphatic immunotherapy (ILIT), allergen is injected into the lymph node under ultrasound guidance. ILIT is complete after 3 treatment visits, may be more effective than and may have markedly fewer side effects than presently available methods of AIT. The investigators plan a randomized, parallel group, open-label, prospective case-control study to assess immunological changes in lymph node and peripheral blood after intralymphatic (ILIT) or subcutaneous (SCIT) immunotherapy with POLVAC. The intervention consists of one ultrasound-guided injection of allergen into inguinal lymph node or subcutaneous injection 1 cm next to the lymph node. Intervention quality (accuracy of injection) will be assessed by the administering physician during treatment and via video recording on the ultrasound device. Side effects associated with treatment will be recorded by the patients for 3 days after the injection. The effect of intralymphatic or subcutaneous injection on lymph node tissue and immunoglobulins E and G4 in serum as well as cellular analyses of lymph node tissue and peripheral blood will be determined in samples taken during the trial. The primary effect parameter is the effect of a single intralymphatic allergen injection on immunological parameters as well as allergen delivery to the lymph node as compared with a single subcutaneous injection.
The motivation-enhancing intervention is designed for participants in the ILIT.NU trial. The participants are patients with hay fever who are treated with a vaccination in an inguinal lymph node. The motivation-enhancing intervention is a web-based app developed in collaboration with patient partners and is intended to increase retention and reporting in the ILIT.NU trial.
The ragweed Ambrosia artemisiifolia is spreading in northern Europe due to climate change. The pollen are considered highly allergenic and might trigger allergy symptoms at much lower concentrations than e.g. grass or birch pollen. This study aims to determine threshold concentrations for ragweed and birch pollen in patients with seasonal allergic rhinitis. Participants will be exposed in an allergen challenge chamber that was technically modified to maintain very low and stable pollen concentrations for several hours. The study design is adaptive, where the pollen concentrations are escalated or de-escalated based on interim analysis of resulting allergic symptoms.
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.
This prospective multicentric academic NAPT study aims to compile a database of all patients who initiate immunotherapy. The NAPT will take place before, during and after AIT to evaluate the cost and effectiveness of the treatment. The study consists of 4 visits and 2 telephone contacts that are repeated annually for 3 years. This study will be conducted in 2 hospitals: UZ Leuven and AZ ST.

In recent years, a number of randomized controlled trials have confirmed the efficacy and safety of acupuncture in the treatment of allergic rhinitis (AR). Indeed, the latest American clinical guidelines recommended acupuncture treatment for AR patients who are interested in non-pharmacological treatment. In conventional acupuncture treatment for AR, needles are inserted at specific acupoints in the body; with several studies demonstrating acupuncture of sphenopalatine ganglion (SPG) to improve nasal symptoms and quality of life in nasal inflammatory diseases. The investigators hypothesize that, compared with sham acupuncture and rescue medication (RM), active SPG acupuncture combined with RM would lead to greater improvements in symptoms score and reduction in overall need for antihistamines. To test this hypothesis the investigators design a randomized, double blind, controlled trial to evaluate the efficacy of SPG acupuncture in pollen-induced seasonal AR patients and to explore the potential underlying mechanisms.
