Characteristics and progression of childhood-onset and adult-onset eosinophilic esophagitis.

BACKGROUND AND AIM: The prevalence and incidence of eosinophilic esophagitis (EoE) has been increasing over recent years. However, the natural history remains incompletely understood particularly the differences in disease characteristics and progression of childhood-onset and adult-onset EoE. The aim of this study was to evaluate the disease characteristics and progression of childhood-onset and adult-onset EoE. METHODS: A cross-sectional, questionnaire-based study, on 87 adults and 67 children from 2 major tertiary hospitals in South Australia was conducted. Data of those who were diagnosed with EoE between 1999 and 2018 were collected and correlated with medical records. RESULTS: Of the 87 adults with EoE, 34 (39%) were diagnosed at the age of < 18 years (childhood-onset EoE). Reflux symptoms were more common in childhood-onset EoE, whereas asthma was more common in adult-onset EoE. The median duration of symptoms prior to diagnosis of EoE was > 1-4 years in childhood-onset disease (44%) and ≥ 10 years in adult-onset disease (34%). Food impaction was significantly more common on initial presentation in those with adult-onset EoE, whereas weight loss was more common in childhood-onset EoE. At the time of questionnaire, regurgitation, abdominal pain, and bloating were more common in childhood-onset EoE. Those with childhood-onset EoE were more likely to have multiple symptoms at questionnaire when compared with their adult-onset counterparts. In both groups, 15% (5/34 childhood-onset EoE and 8/53 adult-onset EoE) were asymptomatic at the time of questionnaire. CONCLUSION: Childhood-onset EoE appears to be a progressive disease from childhood to adulthood, however with more inflammatory-type symptoms post transition compared to those with adult-onset EoE.

Depressive symptom trajectories in late adolescence and early adulthood: A systematic review.

OBJECTIVE: In adolescents and young adults, depressive symptoms are highly prevalent and dynamic. For clinicians, it is difficult to determine whether a young person reporting depressive symptoms is at risk of developing ongoing mood difficulties or whether symptoms form part of a transient maturational process. Trajectory analyses of longitudinally assessed symptoms in large cohorts have the potential to untangle clinical heterogeneity by determining subgroups or classes of symptom course and their risk factors, by interrogating the impact of known or suspected risk factors on trajectory slope and intercept and by tracing the interrelation between depressive symptoms and other clinical outcomes over time. METHOD: We conducted a systematic review of trajectory studies conducted in cohorts including people aged between 15 and 25 years. RESULTS: We retrieved 47 relevant articles. These studies suggest that young people fall into common mood trajectory classes and that class membership and symptom course are mediated by biological and environmental risk factors. Furthermore, studies provide evidence that high and persistent depressive symptoms are associated with a range of concurrent health and behavioral outcomes. CONCLUSION: Findings could assist in the formulation of novel concepts of depressive disorders in young people and inform preventive strategies and predictive models for clinical practice.
