BACKGROUND In addition to immediate reactions, late adverse reactions to iodinated contrast media (ICM) were reported in 2% to 5% of patients exposed to ICM and, as a consequence, have recently gained more attention. A few well-documented case reports postulate a hypersensitivity mechanism. OBJECTIVE The aim of this study is to demonstrate a T(More)
Five hundred sixty-nine subjects routinely underwent skin prick tests for latent sensitization to latex. The study of risk factors included skin tests to inhalant allergens, to diagnose atopy, and a questionnaire aimed at revealing frequent exposure to latex such as the wearing of gloves, multiple surgical procedures, or urinary catheterization. The(More)
Mesangial IgA in IgA nephropathy are dimers with a J chain but no poly-Ig receptor. This molecular structure has led to the hypothesis that these IgA are issued from the lamina propria of mucosal areas, reaching the kidney by way of the peripheral blood. The availability of hybridomas producing IgA dimers provided an opportunity to test this hypothesis in a(More)
About 10% of health care professionals vaccinated against hepatitis B virus (HBV) fail to develop protective antibodies. We tested the capacity of peripheral blood lymphocytes from 121 health care professionals, including 76 non-responders, to proliferate to four HBV vaccines, examined the proliferating cells' subset, production of IFN-gamma, IL-4 and(More)
The diagnosis of pulmonary sarcoidosis relies in part on the observation of alveolar CD4+ lymphocytosis. However, this criterion is not fully discriminative because this anomaly is also found in other types of lung diseases. Among other possible distinctive criteria, we investigated the expression of lymphocyte-addressing molecules, which could differ(More)
Occupational allergic rhinitis to proteins is increasing in importance. Two cases of latex-induced rhinitis are reported in a nurse's aid and a laboratory technician. A crossed food allergy is quoted. Positive prick-tests and specific IgE to latex have been demonstrated in both cases. A double-blind nasal challenge test has been performed with the rinse(More)
Fourteen patients suffering from perennial allergic asthma linked to mono-sensitivity to the house dust mite were studied. An initial bronchoalveolar lavage with standard cytology as well as a study of the T lymphocyte subpopulations (CD3, CD4, CD8, Leu 7) and B cells (CD19) was carried out, representing the basal situation. Four weeks later an allergic(More)
The role of flavouring was studied in eleven children under five years of age suffering from severe atopic dermatitis. In all cases, the dietary questionnaire showed the high daily intake of natural vanilla, vanillin, natural and artificial flavouring. Double-blind oral provocation tests were carried out with balsam of Peru (225 mg), natural vanilla (50(More)
The growing worldwide prevalence of food allergies is drawing attention to the risk of allergenic proteins found in intravenous medicinal products, particularly anaesthetics. Propofol induced anaphylaxis has been described. The presence of soybean oil and egg lecithins in the lipid emulsion highlights their suspected responsibility in certain cases. We(More)
