Multiple Allergen Simultaneous Test for Food Allergens Cannot Screen Wheat-Dependent, Exercise-Induced Anaphylaxis and α-Gal Syndrome.
Screening tests for specific immunoglobulin E (sIgE) to food allergens, such as the multiple allergen simultaneous test (MAST), are widely used in patients with suspected food allergies in South Korea. We evaluated whether MAST could effectively screen wheat-dependent exercise-induced anaphylaxis (WDEIA) and α-gal syndrome (AGS). We retrospectively reviewed patients with WDEIA and AGS diagnosed with unequivocal history and positive sIgE results for omega-5 gliadin and α-gal using ImmunoCAP, respectively. ⋯ Among those positive for α-gal sIgE, 32 (85.7%) and 37 (96.4%) tested positive for pork- and beef-sIgE using ImmunoCAP, respectively, whereas MAST could not detect sIgE for pork and beef (0%, 0/17). MAST for sIgE to food allergens cannot screen WDEIA and AGS. The tests for sIgE to a specific component of food allergen, such as omega-5 gliadin for WDEIA and α-gal for AGS, should be used to screen WDEIA and AGS.

Smoking Experience before Adulthood Is Associated with an Increased Risk of Developing Ulcerative Colitis in Adult Ex-Smokers.
Smoking may have a protective role in developing ulcerative colitis (UC) but have the opposite effect on Crohn's disease (CD). This study aimed to determine the risk of developing inflammatory bowel disease (IBD) according to smoking status and onset age of smoking. ⋯ Ex-smokers who started smoking at a young age have a high risk of UC, even after adjusting for the smoking amount.

Predisposing Risk Factors Affecting Reversibility of Left Ventricular Diastolic Filling Pattern in Patients with Preserved Ejection Fraction.
Improvement of left ventricular (LV) diastolic dysfunction (DD) is known to be a good prognostic factor in patients with heart failure with reduced ejection fraction (EF). In the present study, we investigated the predisposing risk factors affecting the reversibility of LV diastolic filling pattern (DFP) in patients with preserved EF. ⋯ We identified that PAF was an independent predisposing risk factor of the unimproved LVDFP in patients with pseudonormal LVDFP and preserved EF. Therefore, early detection and management of PAF might be required in patients with LVDD and preserved EF to prevent adverse cardiovascular events.
