Abstract:
BACKGROUND: Several measures have been used to assess the health-related quality of life (HRQoL) of patients with eosinophilic oesophagitis (EoE).
AIMS: To systematically review these HRQoL measures, to appraise measurement properties of specific instruments and to evaluate determinant factors influencing HRQoL in paediatric and adult EoE patients.
METHODS: We searched the PubMed, Embase, Scopus, Web of Science (WOS) and PsycINFO databases for documents providing original information on the development of measurement tools and/or evaluation of HRQoL outcomes in EoE patients of all ages.
RESULTS: Of the 596 references identified, data was collected from 34 studies (with only 16 of them being published as full papers) including a total of 1,689 individual patients. Three disease-specific HRQoL measures in EoE covering different aspects of patients' lives and developed in English, were scored positive regarding measurement properties. The PedsQL inventory (including parent and child report forms) and the Peds-QoL EoE module were the generic and specific instruments respectively used in children, while the SF-36 and EoE-QoL-A were the most used questionnaires in adults. Patients with EoE show an impaired HRQoL compared to controls, which greatly depends on symptom severity and disease duration. Severity of endoscopic features and female gender may also determine an impaired HRQoL. The effect of treatments on HRQoL requires further assessment.
CONCLUSIONS: HRQoL is a relevant outcome that should be considered in clinical practice and research of EoE. Further validation studies in several languages and populations are required to support the use of disease-specific HRQoL measures.
