The economic and social burden of congenital thrombotic thrombocytopenic purpura (cTTP) in Italy

Background: Congenital thrombotic thrombocytopenic purpura (cTTP) is a rare genetic disorder characterized by an abnormal clotting process leading to serious health complications such as thrombocytopenia and hemolytic anemia. Despite its clinical significance, the estimated broader economic and social impacts in Italy on patients and society remain underexplored. Methods: A detailed questionnaire, developed and validated by a panel of cTTP experts, was distributed to healthcare professionals and patient associations to gather comprehensive data on the economic and social burden of cTTP in Italy. The study was focused on direct and indirect costs associated with the disease management of 15 patients with cTTP, as well as out-of-pocket expenses incurred by patients. Results: The analysis revealed that of the 15 patients diagnosed with cTTP in Italy, 60% were adults aged 40-55 years. Productivity loss and diminished quality of life dominated the economic burden of cTTP, accounting for 81.05% of total costs. Direct medical costs, while substantial, represented a smaller portion of the overall financial impact. Additionally, out-of-pocket expenses, though constituting the smallest fraction, underscored the financial contributions made by patients towards their own care management. Conclusion: The findings underscore the need for a multidisciplinary and holistic approach to cTTP management that extends beyond the clinical treatment. Addressing the economic and social implications of the disease is crucial for improving patient well-being and ensuring the sustainability of healthcare systems. The study advocates for increased awareness, research, and access to care for cTTP patients, highlighting the importance of comprehensive support networks to mitigate the disease’s broader societal impacts, estimated to be around 2 million euro for 15 patients in 10 years.
