Activation state of circulating eosinophils in nasal polyposis.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common disease with an uncertain pathophysiology. It is characterized by polyps rich in eosinophils, with an activation status already investigated at the tissue level. In a group of CRSwNP patients, we assessed the activation status of circulating eosinophils in the blood before migration into tissues.

Oral probiotic treatment of Lactobacillus rhamnosus Lcr35 prevents visceral hypersensitivity to a colonic inflammation and an acute psychological stress.

Aims: This study evaluated the efficacy of a repeated oral treatment with two active pharmaceutical ingredients (Lcr Lenio and Lcr Restituo ) derivated from the probiotic bacterial strain Lactobacillus rhamnosus Lcr35 in two animal models mimicking different features of irritable bowel syndrome (IBS). IBS is characterized by visceral pain associated with alteration of bowel transit. IBS patients present visceral hypersensitivity with peripheral and central origins.

Slight Pro-Inflammatory Immunomodulation Properties of Dendritic Cells by Gardnerella vaginalis: The "Invisible Man" of Bacterial Vaginosis?

Bacterial vaginosis (BV), the most common genital infection in reproductive-aged women, is associated with increased risk of sexually transmitted infections. Its etiology remains unclear, especially the role of Gardnerella (G.) vaginalis, an anaerobic bacterium characteristic of the BV-alteration of the vaginal ecosystem.

Binding Potency of Heparin Immobilized on Activated Charcoal for DNA Antibodies.

In vitro experiments showed that heparin adsorbed on activated charcoal can bind antibodies raised against native and single-stranded DNA in a diluted sera pool with a high level of these DNA. Thus, heparin used as anticoagulant during hemosorption procedure can demonstrate supplementary therapeutic activity resulting from its interaction with various agents involved in acute and chronic inflammatory reactions such as DNA- and RNA-binding substances, proinflammatory cytokines, complement components, growth factors, etc. Research and development of heparin-containing carbonic adsorbents for the therapy of numerous inflammatory and autoimmune diseases seems to be a promising avenue in hematology.

Airborne pollen levels and drug consumption for seasonal allergic rhinoconjunctivitis: a 10-year study in France.

Background: Few time-series studies, and none lasting longer than 4 years, have investigated the etiology of treated seasonal allergic rhinoconjunctivitis (SAR) on the basis of anti-allergic medication prescriptions. The aim of this article was to study the short-term relationship between pollen exposure and drug-treated SAR over 10 years in an urban area in central France.

Methods: A SAR case was defined as the association between an oral antihistamine and a local anti-allergic drug on the same prescription.
