Abstract BackgroundCholinergic urticaria (CholU) is classified into several subtypes: 1) conventional sweat allergy-type CholU (conventional SAT-CholU), 2) CholU with palpebral angioedema (CholU-PA), 3) CholU with acquired anhidrosis and/or hypohidrosis (CholU-Anhd), and other rare type; 1) and 2) include SAT based on pathogenesis. There have been no studies on differences in the prevalence of bronchial asthma among the CholU subtypes. This is investigated in the present study by evaluating the bronchial responsiveness of each subtype.MethodsPatients 16–80 years of age with CholU were enrolled. We analyzed bronchial responsiveness, respiratory symptoms, and exhaled nitric oxide (FeNO). Bronchial responsiveness was assessed using the methacholine dose indicator Dmin.ResultsA total of 11 patients with conventional SAT-CholU, 11 with CholU-PA, and 11 with CholU-Anhd were enrolled. Median log10 Dmin (interquartile range) of patients with conventional SAT-CholU, CholU-PA, and CholU-Anhd was 0.381 (−0.829, 1.079), 0.717 (0.249, 0.787), and 1.318 (0.121, 1.699), respectively (p=0.516). Dmin was lower in patients with SAT (conventional SAT-CholU and CholU-PA) than in those with CholU-Anhd, although the differences among the 3 types were not significant. Respiratory symptoms evaluated using the International Primary Care Airways Group questionnaire were less frequently observed in CholU-Anhd (0 [0, 1]) than in conventional SAT-CholU (1 [0–2]) or CholU-PA (1 [1–3]) (p=0.049). FeNO of patients with conventional SAT-CholU, CholU-PA, and CholU-Anhd was 23 (18.5, 65.0), 39 (32.0, 59.5), and 25 (19.0, 33.0) ppb, respectively (p=0.237). One of 11 conventional SAT-CholU patients (9.1%) and 6 of 11 CholU-PA patients (54.5%) required treatment for bronchial asthma.ConclusionsLog Dmin tended to be lower in patients with SAT-CholU than in those with CholU-Anhd. Distinguishing between CholU subtypes may reveal different degrees of bronchial responsiveness based on a distinct pathogenesis.Trial registration numberUMIN 000025669; https://upload.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno=R000027550

Abstract Background: Cholinergic urticaria (CholU) is classified into several subtypes: 1) conventional sweat allergy-type CholU (conventional SAT-CholU), 2) CholU with palpebral angioedema (CholU-PA), 3) CholU with acquired anhidrosis and/or hypohidrosis (CholU-Anhd); 1) and 2) include SAT based on pathogenesis. There have been no studies on differences in the prevalence of bronchial asthma among the subtypes. We evaluated the bronchial responsiveness of each subtype. Methods: We analyzed bronchial responsiveness using the methacholine dose indicator Dmin, respiratory symptoms, and exhaled nitric oxide (FeNO). Results: Median log10 Dmin (interquartile range) of patients with conventional SAT-CholU (n=11), CholU-PA (n=11), and CholU-Anhd (n=11) was 0.381 (−0.829, 1.079), 0.717 (0.249, 0.787), and 1.318 (0.121, 1.699), respectively (p=0.516). Respiratory symptoms evaluated using the International Primary Care Airways Group questionnaire were less frequently observed in CholU-Anhd (0 [0, 1]) than in conventional SAT-CholU (1 [0–2]) or CholU-PA (1 [1–3]) (p=0.049). FeNO of patients with conventional SAT-CholU, CholU-PA, and CholU-Anhd was 23 (18.5, 65.0), 39 (32.0, 59.5), and 25 (19.0, 33.0) ppb, respectively (p=0.237). Conclusions: Log Dmin tended to be lower in patients with SAT-CholU than in those with CholU-Anhd. Distinguishing between CholU subtypes may reveal different degrees of bronchial responsiveness based on a distinct pathogenesis.

Abstract Background Elderly asthmatics represent an important group that is often excluded from clinical studies. In this study we wanted to present characteristics of asthmatics older than 70 years old as compared to younger patients. Methods We conducted a retrospective analysis on a series of 758 asthmatics subdivided in three groups: lower than 40, between 40 and 70 and older than 70. All the patients who had a successful sputum induction were included in the study. Results Older patients had a higher Body Mass Index, had less active smokers and were more often treated with Long Acting anti-Muscarinic Agents. We found a significant increase in sputum neutrophil counts with ageing. There was no significant difference in blood inflammatory cell counts whatever the age group. Forced expiratory volume in one second (FEV1) and FEV1/FVC values were significantly lower in elderly who had lower bronchial hyperresponsiveness and signs of air trapping. We found a lower occurrence of the allergic component in advanced ages. Asthmatics older than 70 years old had later onset of the disease and a significant longer disease duration. Conclusion Our study highlights that asthmatics older than 70 years old have higher bronchial neutrophilic inflammation, a poorer lung function, signs of air trapping and lower airway variability. The role of immunosenescence inducing chronic low-grade inflammation in this asthma subtype remains to be elucidated.
