Experience of follow-up, quality of life, and transition from pediatric to adult healthcare of patients with tuberous sclerosis complex.

INTRODUCTION

Tuberous sclerosis complex (TSC) is a multisystemic genetic disease with high clinical variability and age-related manifestations. These characteristics add to the complexity of transition to adulthood. This study aimed to explore the perception of medical follow-up and transition experience in a large group of patients with TSC who presented epilepsy in childhood.

METHOD

This multicenter French study included patients with TSC aged 18 years or older who developed epilepsy before the age of 16 years. A questionnaire specifically designed for the study explored patients' opinion through 270 questions covering different aspects of their social, familial, professional, and medical courses.

RESULTS

The questionnaire was sent to 72 patients, and 60 patients were included in the study (83% response rate) with a mean age of 32 years (18-55 years). Cognitive impairment was present in 80% of patients, and half of questionnaires were completed by the family. Pediatric care was coordinated by the child neurologist and was more regular and multidisciplinary than adult care. Epilepsy had the best follow-up followed by renal issues. Unmet needs were identified for psychiatric and behavioral disorders, both in children and adults. Respondents considered the help in achieving autonomy better in adult care. Only 50% of patients with a normal intellectual development had clear knowledge about their disease and the need for a regular monitoring. Two-thirds of respondents estimated that they had a transition experience between 16.5 and 21-year-old, considered as good in 60% of them. Seventy percent felt continuity between pediatric and adult care, and only 3% of respondents felt that their care would have been better if they were still followed in pediatric healthcare system. The change of care structure and/or caregivers was the most stressful factor during transition and transfer.

CONCLUSION

This study highlights persistent issues in the regularity and coordination of the follow-up of patients with TSC despite established international guidelines. Although most patients had a positive transition experience, there is still an urgent need to optimize transition programs. This would be essential to maintain care continuity between pediatric and adult health systems, especially for patients with TSC with epilepsy and high rate of cognitive and psychiatric impairments.
