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

ABSTRACT:

Background

Chronic systemic inflammation accelerates early vascular ageing. Atopic sensitization and allergic diseases may involve increased inflammatory activity. This study aimed to assess whether atopic sensitization and allergic diseases were associated with altered vascular biomarkers in Norwegian adolescents.

Methods

Distensibility coefficient of the common carotid arteries, carotid intima-media thickness and atopic sensitization (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.

Results

Atopic sensitization was found in 33 (34.7%) of the adolescents. Symptomatic allergic disease was found in 11 (33.3%) of those with atopic sensitization. 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 sensitization nor of allergic disease, with distensibility coefficient of the common carotid arteries and carotid intima-media thickness.

Conclusions

Our results do not support the assumption of an adverse impact of atopic sensitization 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 sensitization.

Project description:BackgroundMigraine with aura is associated with an increased risk of cardiovascular disease, yet the pathophysiology is unknown. Suggested underlying mechanisms of aura formation point into the direction of an abnormal vasoreactivity that also extends to the extracranial vasculature.MethodsIn the Early Vascular Ageing Tyrol study, a community-based non-randomized controlled trial conducted in 45 schools and companies in Tyrol (Austria) and South-Tyrol (Italy) between May 2015 and September 2018 aiming to increase cardiovascular health in adolescents, headache syndromes were classified according to the International Classification of Headache Disorders in a face-to-face interview. Carotid-femoral pulse-wave-velocity was measured by applanation tonometry and carotid intima-media-thickness by high-resolution ultrasound of the distal common carotid arteries. Differences in pulse-wave-velocity and carotid intima-media-thickness in youngsters with migraine with aura were compared respectively to those without headache and with other headaches by multivariable linear regression analysis.ResultsOf the 2102 study participants 1589 were aged 14 to 19 (mean 16.8) years and had complete data. 43 (2.7%) reported migraine with aura and 737 (46.4%) other headaches. Mean pulse-wave-velocity was 6.17 m/s (± 0.85) for migraine with aura, 6.06 m/s (± 0.82) for all other headaches and 6.15 (0.95) m/s for participants without headaches. Carotid intima-media-thickness was 411.3 µm (± 43.5) for migraine with aura, 410.9 µm (± 46.0) for all other headaches and 421.6 µm (± 48.4) for participants without headaches. In multivariable linear regression analysis, we found no differences in carotid-femoral pulse-wave-velocity or carotid intima-media-thickness in young subjects with migraine with aura, all other headaches, or no headaches.ConclusionsIn line with previous large-scale studies in adults, we could not demonstrate relevant associations of migraine with aura with markers of arterial stiffness or subclinical atherosclerosis making early vascular ageing an unlikely pathophysiological link between migraine with aura and cardiovascular diseases.Trial registrationFirst registered on ClinicalTrials.gov 29/04/2019 (NCT03929692).

Project description:ObjectivesPrevalence of child and adolescents' overweight and obesity in low- and middle-income countries has increased dramatically. Simultaneously, the incidence of pre-hypertension/hypertension is also increasing in children, which, in turn, predisposes these children to the risk of cardiovascular disease (CVD) in later life. The present study assessed cardiometabolic risk factors and early indicators of vascular dysfunction in adolescents from a low socio-economic rural area in South Africa.DesignCross-sectional cohort study.SettingThe study was conducted in public schools in Mthatha, OR Tambo district municipality, Eastern Cape Province, South Africa.ParticipantsA total of 244 adolescents (188 females) of African ancestry aged 13-16 years were enrolled.Primary and secondary outcome measuresAnthropometric and haemodynamic measures and pulse wave velocity (PWV) were related to overweight/obesity and hypertension. Blood markers of cardiometabolic syndrome were assessed as well as vascular function (via PWV).ResultsOne-third (33.0%) of the adolescents exceeded the age and sex-specific body mass index percentiles for overweight (≥85th) or obesity (>95th) with a prevalence of 61.1% pre-hypertensives in this group. Overweight/obesity and hypertension were associated with higher triglycerides (lean:overweight: 0.79<1.01 mmol/L; normotensive:hypertensive: 0.82<0.89 mmol/L). Fasting glucose was higher in hypertensive as compared to normotensive adolescents (4.85>4.69 mmol/L, p<0.05). PWV was elevated in 25.9% of the children and significantly correlated with asymmetric dimethylarginine and systolic blood pressure (p<0.001).ConclusionOverweight/obesity and hypertension show a high prevalence in rural South African youth. Almost half of the studied adolescents are at risk for developing CVD. The high association between cardiometabolic risk factors and PWV further suggests that hypertension in adolescents may promote the progression of CVD in adulthood. Early detection of those at risk and the implementation of preventive strategies in underprivileged young people is urgently needed to stop the progression of vascular damage and manifestation of CVD in rural African children.
