Filter by:The objective of this clinical trial was to assess the efficacy and safety of cetirizine HCl syrup vs. loratadine syrup vs. placebo syrup in the treatment of SAR in children 6 to 11 years old.
Rhinovirus (RV) infections represent the most common cause of asthma exacerbations in children and adolescents. The investigators hypothesize that the immune responses generated in the nose of allergic rhinitics and asthmatics underlie subsequent systemic modulation of the immune system, and that - in susceptible individuals (i.e., those with pre-existing asthma) - this modified nasal milieu is responsible for the asthma exacerbation. Open label single center study in asthmatics as well as allergic rhinitis (AR) and healthy controls. All subjects will undergo good manufacturing practice (GMP) RV16 inoculation and responses will be compared between the 3 cohorts.
The prevalence of allergic diseases (atopic dermatitis, asthma, rhinitis, conjunctivitis and food allergy) has increased dramatically in industrialized countries over the last 20-30 years. Allergic diseases are present especially in children and young adults, but all age groups are affected, with variations across countries and age. To propose new therapies, the investigators must first understand the physiopathology. Since their discovery the regulatory T cells have continued to be the subject of work to understand their role in maintaining immune homeostasis in the human body but also their involvement in autoimmune diseases, inflammatory diseases, transplants of solid organs or fluids and allergic diseases. It was identified two broad classes of regulatory T cells: - T cells = natural regulators acquisition of a phenotype and a regulatory function right out of the thymus ( CD25 + / CD127 + low / FoxP3 +). - T cells induced regulators = acquisition of a phenotype and a regulatory function on the periphery depending on the cytokine micro-environment. Phenotypic characterization of these is less obvious and even more so than during the last ten years several induced regulatory T cell populations have been described ( eg, Tr1 ). A new subpopulation of T cells induced in patients with inflammatory bowel disease recently identified have a particular phenotype as bearing the CD4 and CD8 double marking with a regulatory phenotype. These regulatory T cells are also induced a specific of a commensal intestinal bacterium (Faecalibacterium prausnitzii). Regarding allergies, it has been widely demonstrated a relationship between changes of the intestinal microbiota and the occurrence of allergic diseases. The investigators would therefore propose a cross-sectional study, single-center, controlled, single blinded to study the role of T cells called double positive induced regulators DP8 to compare the frequency and the regulatory function of specific DP8 of Faecalibacterium prausnitzii in atopic dermatitis, asthma and allergic rhinitis compared to control samples.
This is an observational prospective study to assess the tolerability and safety of treatment of SCIT Allergovac Poliplus polymerized in depot presentation. The study drug will be administered either by a 1 day Schedule or by a rapid Schedule (3 increasing weekly doses at initiation period till maintenance dose is reached) The study population is both: adult and child, polysensitized to at least 2 allergen sources with rhinitis or allergic rhinoconjunctivitis. Patients may also present a concomitant mild or moderate asthma. The assignment of a patient to a particular therapeutic strategy will not be decided in advanced by a trial protocol but will be determined by routine clinical practice. The decision of the investigator to prescribe a particular treatment will be clearly dissociated from the decision to include the patient in the study. The patients will not suffer any intervention, whether diagnostic or monitoring, other than the usual in clinical practice.
This is a pilot cross-sectional study of measured transcutaneous CO-oximetry in children with inflammatory and non-inflammatory conditions.
Allergic rhinitis is a common condition that affects adults as well as children and adolescents, often with impaired quality of life. Patients often report a poor level of satisfaction with the effectiveness of their treatment and are always looking for more drug combinations to improve their symptom. Several tools exist for assessing control of allergic rhinitis, but none has been validated in adolescents or in children. A study conducted in 2008, resulted in the validation of a self-administered control test of allergic rhinitsis (ARCT) in patients from 12 years of age. However, this study included only 67 adolescents aged 12 to 17 years old and lacked power. In this new study,the investigators propose, following exactly the same procedure as the pilot study of 2008, to confirme the validation of unmodified Adult questionnaire in adolescents 12 to 17 years inclusive.
Caucasian male and female participants age 18 years of age and older will be enrolled in this study if they have known birch or peanut allergies or known to be non-atopic. Participants will undergo skin testing to confirm their allergies if not completed in the last 12 months. Medications and medical history will be captured with a focus on atopic disorders. Participants will undergo birch and peanut patch testing to assess penetration and if potential correlation exists with filaggrin genotyping and phenotyping. Blood samples will be drawn from participants and DNA isolated for genotyping of null mutations in filaggrin.
The main objective of RinASol project is to assess in patients with seasonal Allergic Rhinitis the effect of hypertonic saline solution NACL 3%+NAHCO3 vs the effect of standard saline solution on nasal inflammation by means of nasal cytology. The secondary objective is the symptom score assessment by T5SS Questionnaire (Total Symptom Score 5)
The clinical relevance of an allergen-specific sensitization is proven e.g., by allergen challenge tests in clinical routine. Several protocols for different challenge tests such as nasal (NPT), bronchial (BPT) or conjunctival provocation test (CPT) have been proposed. Beneath others, the CPT is broadly used in both clinical trials and routine because of its feasibility. However, there is no internationally harmonized standard regarding the clinical interpretation of CPT results as well as a lack of validation of a specific outcome score. Therefore, this trial aims to investigate and validate a new scoring system for CPT results in order to provide this test as a useful method in future clinical trials.
The investigators will perform double-blinded placebo-controlled randomized clinical trial which evaluates the efficacy and safety of allergen-specific intralymphatic immunotherapy (ILIT) for allergens including Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), cat, and dog that are sensitized and provoke rhinitis-related symptoms in patients with allergic rhinitis (AR), using allergen extracts for allergen-specific immunotherapy (Tyrosine S, Allergy Therapeutic, West Sussex, UK).
