Effect Of Probiotic Lactobacillus Paracasei Lp-33 For The Management Of Rhinitis In People Sensitized To Allergens
Summary
The aim of the study is to show an improvement of quality of life on the 5th week of product consumption (probiotic Lactobacillus paracasei LP-33)(as assessed by RQLQ global score) in subjects with persistent allergic rhinitis currently treated with Loratadine or oral anti-histaminic treatment.
Description
Oral H1-antihistamines are first treatment recommended for allergic rhinitis (Bousquet et al, 2008) however they do not completely alleviate symptoms. This new study will therefore assess the effect of Lactobacillus paracasei LP-33 in the management of nasal and ocular symptoms, in addition to H1-antihistamines treatment. The main objective is to evaluate the effect of Lactobacillus paracasei LP-33 on quality of life. Additionally allergic rhinitis symptoms (nasal and eye symptoms) and immunological parameters will be evaluated, before and during the supplementation. Lactobacillus paracasei LP-33 is targeting the general population and improving quality of life of people sensitized to allergens. The study will be conducted in Europe on adult subjects with persistent allergic rhinitis.

Medical and Biotech [MESH] Definitions
Rhinitis, Vasomotor
A form of non-allergic rhinitis that is characterized by nasal congestion and posterior pharyngeal drainage.
Rhinitis, Allergic, Seasonal
Allergic rhinitis that occurs at the same time every year. It is characterized by acute CONJUNCTIVITIS with lacrimation and ITCHING, and regarded as an allergic condition triggered by specific ALLERGENS.
Therapeutic Misconception
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
Placebo Effect
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
Sick Building Syndrome
A group of symptoms that are two- to three-fold more common in those who work in large, energy-efficient buildings, associated with an increased frequency of headaches, lethargy, and dry skin. Clinical manifestations include hypersensitivity pneumonitis (ALVEOLITIS, EXTRINSIC ALLERGIC); allergic rhinitis (RHINITIS, ALLERGIC, PERENNIAL); ASTHMA; infections, skin eruptions, and mucous membrane irritation syndromes. Current usage tends to be less restrictive with regard to the type of building and delineation of complaints. (From Segen, Dictionary of Modern Medicine, 1992)
