Abstract

Background: Iodinated and gadolinium-based contrast media (ICM; GBCM) induce immediate hypersensitivity (IH) reactions. Differentiating allergic from non-allergic IH is crucial; allergy contraindicates the culprit agent for life. We studied frequency of allergic IH among ICM or GBCM reactors. Methods: Patients were recruited in 31 hospitals between 2005 and 2009. Clinical symptoms, plasma histamine and tryptase concentrations and skin tests were recorded. Allergic IH was diagnosed by intradermal tests (IDT) with the culprit CM diluted 1:10, “potentially allergic” IH by positive IDT with pure CM, and non-allergic IH by negative IDT. Findings: Among 245 skin-tested patients (ICM = 209; GBCM = 36), allergic IH to ICM was identified in 41 (19.6%) and to GBCM in 10 (27.8%). Skin cross-reactivity was observed in 11 patients with ICM (26.8%) and 5 with GBCM (50%). Allergy frequency increased with clinical severity and histamine and tryptase concentrations (p 50% of life-threatening ones. GBCM and ICM triggered comparable IH reactions in frequency and severity. Cross-reactivity was frequent, especially for GBCM. We propose considering skin testing with pure contrast agent, as it is more sensitive than the usual 1:10 dilution criteria.

Abstract

Due to the multiple factors affecting exhaled nitric oxide (NO) value, physicians are often puzzled by the result of a single measurement in asthmatic patients.The aim of this prospective transversal study was to evaluate the relative contributions to exhaled NO fraction (FE(NO)) of the commonly considered major NO determinants, i.e., recent symptoms (upper and lower respiratory tract), atopy (prick skin tests and degree of allergic exposure), and treatment (dose of inhaled corticosteroid [ICS]) to know what information gives a single measure.FE(NO) at 50 mL/s expiratory flow was measured in 199 asthmatic children (141 boys, age: 11.2 years +/- 2.5 years). The allergic risk due to pollen exposure (ARPE index) was independently evaluated by the "Réseau National de Surveillance Aérobiologique."A multivariate analysis of FE(NO) as dependent variable showed that explanatory variables explained 23% of total FE(NO) variance (symptomsatopyICS). In the children without recent symptoms (n = 118), a FE(NO)23 ppb predicted atopy (sensitivity 47%, specificity 85%, p = 0.0006). Multiple regression only showed a trend to significance between FE(NO) and the dose of ICS (p = 0.057, r = - 0.19). Incidentally, despite similar dose of ICS, children under fluticasone (mean +/- SD, 259 +/- 149 microg/day) had lower FE(NO) than those under budesonide (299 +/- 195 microg/day) (median [interquartile], 21 ppb [14-42], n = 55 versus 35 ppb [19-47], n = 104; p = 0.007), which may be due to a higher potency of fluticasone. A relationship between FE(NO) and ARPE index was significant in children with exclusive seasonal sensitisation (n = 31, r = 0.48, p = 0.008).Common exhaled NO determinants weakly explain a single value of FE(NO), which only can confidently predict atopy.
