Triptan treatment is associated with a higher number of red wine-induced migraine episodes: An exploratory questionnaire-based survey.

Aim: Diet, including foods and beverages, affects migraine. Conversely, the influence of migraine therapies on dietary habits is largely unknown. This study aimed at investigating the effects of triptan intake on foods and drinks consumed by adults with migraine with and/or without aura.

Sensitization to cereals and peanut evidenced by skin prick test and specific IgE in food-tolerant, grass pollen allergic patients.

Background: The botanical relation between grass and cereal grains may be relevant when diagnosing food allergy to cereals. The aim was to investigate the diagnostic specificity of skin prick test (SPT) and specific immunoglobulin E (sIgE) tests to cereals and peanut in grass pollen allergic subjects without history of, and clinically reactions to foods botanically related to grass.

Methods: 70 subjects (41 females; mean age 32 years) and 20 healthy controls (13 females; mean age 24 years) were tested by open food challenge (OFC) with cereals and peanut.

[Impaired activation and costimulation of T CD4+ lymphocytes during chronic hepatitis C infection].

Hepatitis C chronic infection occurs in 80% of the cases and eventually leads to cirrhosis and hepatocellular carcinoma. A deficient adaptive immune response has been described during chronic infection which contributes to viral persistence. This altered T cell response could be associated to deficient costimulation signals during priming of T cells.
