In many countries, adult clinics specifically dedicated to adult patients with lysosomal storage diseases (LSDs) do not exist. In Turkey, these patients are managed either by pediatric metabolic specialists or adult physicians who do not specifically specialize in LSDs. In this study, we aimed to identify the unmet clinical needs of these adult patients and their suggestions.

The focus group participants were 24 adult LSD patients. Interviews were conducted in person.

A total of 23 LSD patients and parents of a patient with mucopolysaccharidosis type-3b with intellectual deficit were interviewed, with 84.6% of patients diagnosed after the age of 18 years and 18% of patients diagnosed before the age of 18 years desiring management by adult physicians. Patients with particular physical characteristics or severe intellectual deficit declined the transition. Patients reported structural problems in the hospital and social problems associated with pediatric clinics. They made suggestions to facilitate the possible transition.

With improved care, more patients with LSDs survive into adulthood or receive the diagnosis in adulthood. Children with chronic diseases need to transition to the care of adult physicians when they reach adulthood. Thus, there is an increasing need for adult physicians to manage these patients. In this study, most LSD patients accepted a well-planned and organized transition. Problems were related to stigmatization and social isolation in the pediatric clinic or adult issues with which pediatricians are not familiar. There is a need for adult metabolic physicians. Thus, health authorities should adopt necessary regulations for training of physicians in this field.
