Is atopic sensitisation associated with indicators of early vascular ageing in adolescents?


Chronic systemic inflammation accelerates early vascular ageing. Atopic sensitisation and allergic diseases may involve increased inflammatory activity. This study aimed to assess whether atopic sensitisation and allergic diseases were associated with altered vascular biomarkers in Norwegian adolescents. Distensibility coefficient of the common carotid arteries, carotid intima-media thickness and atopic sensitisation (serum total and specific IgEs) were assessed in 95 Norwegian adolescents, who participated in the RHINESSA generation study. Symptoms of allergic disease were assessed by an interviewer-led questionnaire. Atopic sensitisation was found in 33 (34.7%) of the adolescents. Symptomatic allergic disease was found in 11 (33.3%) of those with atopic sensitisation. Distensibility coefficient of the common carotid arteries appeared to be lower in participants with atopic sensitization than in those without (46.99±8.07*10-3/kPa versus 51.50±11.46*10-3/kPa; p>0.05), while carotid intima-media thickness did not differ between these groups (0.50±0.04mm versus 0.50±0.04mm; p>0.05). Crude, as well as age- and sex-adjusted multiple regression, revealed no significant association, neither of atopic sensitisation nor of allergic disease, with distensibility coefficient of the common carotid arteries and carotid intima-media thickness. The results do not support the assumption of an adverse impact of atopic sensitisation and/or allergic disease on distensibility coefficient of the common carotid arteries and carotid intima-media thickness in Norwegian adolescents. Further research is necessary to study whether the clinical severity of allergic diseases might be more important than the status of allergic disease or atopic sensitisation.
