Introduction
Vitamin D has long been recognized for its crucial role in calcium and bone metabolism, but recent studies have linked it to various hematological malignancies. This study aimed to explore the relationship between vitamin D deficiency and disease characteristics in patients with essential thrombocythemia (ET) and polycythemia vera (PV), both of which are classified as chronic myeloproliferative neoplasms. It involved a retrospective cohort of 73 patients diagnosed according to World Health Organization (WHO) criteria between 2012 and 2018 in Turkey, employing polymerase chain reaction to detect the JAK2 V617F mutation, which is common in these diseases.
Vitamin D and JAK2 V617F Mutation
The findings revealed a concerning prevalence of vitamin D deficiency in both PV and ET patients, with 66.7% of PV patients and 74.2% of ET patients falling below the threshold of 20 ng/mL. Furthermore, the study established a significant correlation between JAK2 V617F mutation positivity and vitamin D deficiency in both patient groups. Specifically, older patients and those harboring the mutation experienced higher rates of thrombosis, emphasizing the need for closer monitoring of vitamin D levels in JAK2 mutation-positive individuals. The results indicate that JAK2 mutations can lead to altered responses in hematopoietic progenitor cells, potentially exacerbated by vitamin D deficiency, suggesting a complex interplay between these factors.
Conclusion
Overall, this study highlights a notably high prevalence of vitamin D deficiency among patients with PV and ET, particularly those who are JAK2 mutation-positive. Given the potential implications for patient management, it is crucial to evaluate vitamin D levels more diligently in these populations. The association found supports the need for further research to illuminate the relationship between vitamin D status and the JAK2 mutation, as it may have significant implications for understanding the pathophysiology of these conditions and guiding treatment strategies. Future studies are warranted to explore whether vitamin D supplementation could positively influence disease outcomes in these patients.
