When toxicity is not just from gluten: a systematic review on financial toxicity and celiac disease

Abstract

Abstract Background With an incidence of up to ∼2% globally, Celiac Disease (CD) is probably one of the most life-long common chronic conditions. Although ‘Financial toxicity’ (FT) has been mainly linked to oncology, significant financial burdens have been described across all healthcare domains, even in CD and to the unexpected economic effort resulting from illness and the need for treatments. This study aimed to investigate the potential relationship between CD and FT. Methods A systematic literature review was performed according to the PRISMA Statement 2020 guidelines. The search query queried the following databases: PubMed, Scopus, CINAHL and APA PsycInfo. No time and study design limits were included. Results 105 articles were found, and 25 were included in the review. The main results revealed that CD impacts physical health and imposes a significant financial burden on patients and their families. FT in CD is primarily due to the high costs of diagnosis, lifestyle changes, and expenses for gluten-free foods. Several studies highlighted the scarce adherence to the therapeutic diet due to the cost of food and poor acceptance of CD. Furthermore, since 2007, there has been increased attention to the difficulty of finding gluten-free products and their expensive fees. All these aspects, even for low-income countries, were faced differently globally, as documented by the heterogeneity of government subsidy policies highlighting the health inequity. Conclusions Considering the prevalence, a comprehensive health assessment with a global health approach should consider clinical, social, and economic aspects. This regard could improve the quality of life for CD patients and ensure fair and personalised access to care, regardless of their geographical location or financial situation. This review has highlighted the fragmentation of resources available internationally, underlining the relevance from a public health point of view. Key messages • Celiac Disease is one of the most common life-long disorders, and financial toxicity is an aspect that should be taken into account also from a public health point of view to ensure health equity. • The gluten-free diet represents an important therapeutic choice in CD; the related expensive fees could increase scarce adherence and worse health outcomes.
