Features of diagnostics and clinical approaches to case management of patients with hereditary angioedema without C1 esterase inhibitor deficiency. Analysis of the clinical case
Abstract
This article describes the clinical, biochemical and genetic features of hereditary angioedema (HAE) with normal level and functional activity of C1 esterase inhibitor. The discussion includes pathogenesis, diagnostics and case management of patients with hereditary angioedema without C1 esterase inhibitor deficiency. The materials of few scientific sources about patients with HAE without C1 esterase inhibitor deficiency in stages and our own clinical case (the female patient of fertile age with a confirmed mutation associated with factor XII (Hageman) deficiency) was given. The article describes the current state of the issue of the algorithm of primary diagnostics and differential diagnostics of HAE without C1 esterase inhibitor deficiency based on international and Russian data. It has been suggested that the new understanding of pathogenesis and treatment of patients with HAE without C1 esterase inhibitor deficiency is encouraging and becoming accessible to the medical society.
Comparative study of Allergy Explorer (ALEX) versus ImmunoCAP platforms
Abstract
Objective. In this study, technical performance of the new multiplex ALEX test was compared with results from ImmunoCAP single tests (tIgE, sIgE) and the multiplex platform ImmunoCAP ISAC sIgE 112. Materials and methods. Eleven whole allergen extracts and corresponding allergen components from different allergen groups were used for the analysis of 64-66 patients’ sera by all three platforms. Results. For the whole allergens, 55% false negative results were obtained with the ALEX test comparing to the ImmunoCAP sIgE tests while for allergen components the ALEX test gives 33% false negative results when compared to ImmunoCAP sIgE test results. Additionally, the ALEX test is characterized by a low dynamic range - the platform demonstrated no results above 36 kUA/L for samples giving >100 kUA/L using ImmunoCAP Specific IgE tests in the analysis of sIgE response to the whole allergens. For the allergen components, ALEX showed no results above 38 kUA/L for samples of up to 150 kUA/L according to ImmunoCAP Specific IgE test results. Comparing to ImmunoCAP single plex tests, ALEX show low dynamic range and poor agreement in quantitative results for tIgE and sIgE both for whole allergens and allergen components, while in the comparison with ImmunoCAP ISAC sIgE 112 platform, the agreement is better, but the sensitivity and dynamic range are still low._ Conclusions. The ALEX test has some serious limitations in its performance comparing to both types of ImmunoCAP platforms.
