Exhaled nitric oxide, bronchial hyperresponsiveness and spirometric parameters in patients with allergic rhinitis during pollen season.

Allergic rhinitis and asthma share common epidemiological features and inflammatory processes. The aim of the present study was to document the influence of natural allergen exposure in exhaled NO (eNO) and in spirometric parameters of patients with seasonal allergic rhinitis(SAR) and to investigate the differences among subjects with positive versus negative bronchial provocation to metacholine(BPMch).Twenty-six non-smoking patients (13F/13M; mean age 28.

Allergy skin testing in predicting adverse reactions to fluorescein: a prospective clinical study.

Purpose: To evaluate allergy skin testing as a diagnostic tool of adverse reactions to fluorescein and whether allergy and previous sodium fluorescein angiography (SFA) act as predisposing factors.

Methods: Patients with adequate indication for fluorescein angiography and normal skin responsiveness were subjected to allergy skin-prick and intradermal tests for fluorescein, followed by SFA. During SFA, adverse reactions were monitored and classified as mild, moderate or severe.

Skin testing and adverse reactions in fluorescein: a prospective study.

Sodium fluorescein (SF) is widely used to assess chorioretinal disorders. Adverse reactions are well documented but the underlying mechanism is still uncertain. The aim of this study was the evaluation of skin testing to predict SF reaction, the identification of possible predisposing factors, and the objective record of the reported reactions.

Sensitization to other foods in subjects with reported allergy to grapes.

The grape is widely produced and consumed in the Mediterranean area. The object of this prospective study was to present in detail the clinical features of patients with documented immunoglobulin E (IgE)-mediated reactions to grapes or its products as well as the existing cosensitizations in other food allergens among this population. Sixty-one patients (27 male patients and 34 female patients), aged 14-52 years (mean, 28.

Grape anaphylaxis: a study of 11 adult onset cases.

Reports of immunoglobulin E (IgE)-mediated allergic reactions to grapes and wine are limited in the literature. Nevertheless, grapes are widely grown and consumed in Mediterranean countries. The object of this prospective study was to present clinical features, in vivo and in vitro allergy testing, and human leukocyte antigen (HLA) serotyping in patients with recurring reactions to grapes and grape products.
