NCT07671222
Sjögren's syndrome is a condition in which the immune system attacks the body's moisture-producing glands. This often causes severe dry eye, leading to discomfort, irritation, blurred vision, and damage to the eye surface. Inflammation plays an important role in this process, and a protein called TNF-alpha is one of the key drivers. This study will test a new eye drop containing infliximab, a medication that blocks TNF-alpha. The goal is to see whether this treatment can safely improve symptoms and signs of severe dry eye in patients with Sjögren's syndrome.
NCT07563439
This study evaluates the effectiveness and safety of PollenVax, a subcutaneous allergen immunotherapy (SCIT) drug developed for the treatment of allergic rhinitis and asthma caused by mugwort (Artemisia vulgaris) pollen. PollenVax contains a recombinant form of Art v 1 - the major mugwort pollen allergen - combined with the adjuvant Montanide ISA-51. It is the first-in-class product of this type designed for an ultra-short treatment course. This is a randomized, double-blind, placebo-controlled Phase II study. Participants will be adults aged 18-65 years diagnosed with moderate-to-severe mugwort pollen-induced allergic rhinitis confirmed by skin prick test and/or specific IgE testing. A total of 138 participants will be randomly assigned to one of three groups: placebo, PollenVax at a cumulative dose of 22 µg of recombinant Art v 1, or PollenVax at 44 µg, administered as four weekly subcutaneous injections. The primary efficacy outcome is the Combined Symptom and Medication Score (CSMS) during the peak mugwort pollen period (PGPP). Safety and tolerability outcomes are co-primary endpoints, assessed throughout the study. Secondary outcomes include daily symptom scores, quality of life (RQLQ/AQLQ), visual analogue scale for rhinoconjunctivitis discomfort, skin prick test reactivity, and immunological markers (Art v 1-specific IgE and IgG). The study is conducted at a single clinical center (Medcenter-Rakhat, Almaty, Kazakhstan). Sponsor: Kazakh National Agrarian Research University (KazNARU).

NCT07436208
Soluble suppression of tumorigenicity 2 (sST2), a decoy receptor of interleukin-33 (IL-33), involved in allergic inflammation. Objectives: This study explored serum sST2 as a biomarker for disease activity and for predicting clinical response to sublingual immunotherapy (SLIT) in patients with house dust mite (HDM) induced AR. Methods: This study included 54 patients with moderate-to-severe AR (MSAR) and 54 healthy controls (HC). Serum sST2, total IgE, HDM-specific IgE, and eosinophil counts were measured. Serum levels of miR-223 were assayed using real-time PCR. Clinical severity was assessed using the total nasal symptom score (TNSS) and visual analogue scale (VAS). MSAR patients received SLIT for 6 months. Treatment response was defined by ≥30% reduction in symptom and medication scores.
NCT07427576
House dust mites are the main source of allergies in indoor environments. They are predominant in coastal areas, with the Canary Islands being the autonomous community with the highest percentage of patients with rhinoconjunctivitis due to sensitisation to these mites (94.7%). Immunotherapy is indicated for the treatment of allergic rhinoconjunctivitis and is capable of altering the natural course of allergic diseases. The aim of the study was to evaluate the efficacy and safety of Clustoid® Max Forte in the treatment of patients with respiratory allergy to Dermatophagoides/Blomia tropicalis.

NCT07385495
Allergic conjunctivitis (AC) causes inflammation of the conjunctiva in response to environmental allergens, affecting a significant percentage of the world population and reducing quality of life. The pathophysiology is poorly understood, lacking effective treatments. MicroRNAs have potential for diagnosing and characterizing inflammatory diseases. This study aims to compare the expression profiles of inflammation-regulating microRNAs (miR-19, miR-23, miR-125b, miR-146a, and miR-155) in serum and tear samples from subjects with AC and healthy subjects to identify biomarkers and therapeutic targets.
NCT07380178

NCT01992835
After an allergen challenge, the allergic inflammatory response disappears spontaneously. The initiation of the resolution of the inflammatory response is now recognized as a dynamic process, involving active biochemical programs that enable inflamed tissues to return to homeostasis. Recent data established key roles of different specific lipid mediators in the endogenous counter-regulation of inflammation and activation of resolution. Only little is known about kinetics of these specialized pro-resolving lipid mediators during acute allergic inflammation. Therefore, the primary propose of our study is to characterize the temporal evolution of cellular inflammation and specific lipid mediators after allergen challenge.

NCT06732414
Background: Allergic or sinus diseases can affect the skin, sinuses, airways, and other parts of the body. Examples include pollen and environmental allergies, food allergies, asthma, and eczema. To learn more about how to prevent and treat these diseases, researchers need to study data, blood, fluid, and tissue samples from people affected by them. Objective: To collect data, blood, fluid, and tissue samples from people with allergic or sinus diseases. Eligibility: People aged 3 to 100 years with allergic or sinus diseases. Design: Participants will have at least one clinic visit, and most participants will have a baseline visit, annual visit, and an end of study visit. The duration of the study is 1 to 3 years. During the first clinic visit, the following procedures will be done to collect data, blood, fluid, and tissue samples: * Blood will be collected. * Cells and fluid may be collected from the inside of the nose using a long swab, and a small piece of skin may be scraped from inside the nose. * Skin cells will be collected by rubbing with a cotton swab. * A urine sample will be collected. * Allergy skin prick tests. Allergy-causing substances will be placed on the back or arm and the skin underneath gently scratched. If the participant is allergic to the substance, the skin may become red, itchy, and swollen locally ( at the site of the test). * Lung function test. Participants will breathe into a machine that measures the air moving in and out of their lungs. * If, as part of their routine care, participants are undergoing procedures such as having nasal polyps removed, skin tissue samples taken, or gastrointestinal biopsies, additional tissues may be collected for this study. * Participants will complete online questionnaires regarding their symptoms, health, and life. Participants may return for more visits for up to 3 years.
