What are the Recent Developments in Global Sitosterolemia Market?

• In June 2025, a clinical study highlighted on ClinicalTrials.gov, sponsored by the National Heart, Lung, and Blood Institute (NHLBI), continued to investigate the use of a higher dose of ezetimibe (40 mg daily) for patients with sitosterolemia. This study aims to determine the safety and effectiveness of a higher dose in lowering plant sterol levels
• In May 2025, a bibliometric analysis published in the Journal of Clinical Lipidology highlighted the growing trend of global scientific collaboration in sitosterolemia research, with a specific focus on genetic analysis. The study found that research institutions are increasingly collaborating to understand the disease's underlying genetics, particularly whole exome sequencing to identify pathogenic variants in the ABCG5 and ABCG8 genes
• In November 2024, the American Society of Hematology (ASH) highlighted that hematologists should consider sitosterolemia as a potential diagnosis in patients presenting with hemolytic anemia and thrombocytopenia. Historically, the disease has been primarily associated with high cholesterol and xanthomas, often leading to a misdiagnosis of familial hypercholesterolemia (FH)
• In October 2023, a case report published in the journal Pediatric Patients with Sitosterolemia highlighted the critical role of next-generation sequencing (NGS) in the accurate diagnosis of sitosterolemia. The report detailed three new cases where NGS custom panels, which included the ABCG5 and ABCG8 genes, were used to differentiate sitosterolemia from other inherited disorders such as familial hypercholesterolemia
• In October 2023, a case study presented at the European Congress of Endocrinology provided a 17-year follow-up on a patient with sitosterolemia treated with ezetimibe. The report concluded that ezetimibe therapy, in combination with dietary management, was effective in preventing the progression of xanthomas (fatty deposits under the skin), which is a key clinical feature of the disease
