Sarcoidosis is a rare disease with the number of patients in the European Union (28 member states), Norway, Iceland and Lichtenstein estimated as ∼102 000 [1, 2]. Some 40% of individuals experience sarcoidosis as a chronic condition, while >60% of individuals find that the disease resolves within 2–5 years [3]. However, it has been shown that patients can still have symptoms that result in a reduced quality of life (QoL) even after clinical signs of disease have disappeared. These symptoms include fatigue, pain, everyday cognitive failure, small fibre neuropathy, exercise limitation and depressive symptoms [4, 5]. Findings from a recent survey of patients and their partners in the Netherlands also showed that sarcoidosis has a significant impact on their lives [6].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
