Sažetak
Myeloproliferative neoplasms (MPN) are rare diseases and their incidence varies from 0.1 to 2.6 per 100 000 persons in Europe. The aim of this study was to summarize diagnosis and laboratory findings in a cohort of patients diagnosed with MPN (polycythemia vera - PV, essential thrombocythemia - ET and primary myelofibrosis - PMF) in University Hospital Center Zagreb between 2011 and 2015. In this study 115 JAK2 V617F positive patients (78 females, 37 males) were included. Patients diagnosis, clinical data, blood count parameters and JAK2 V617F allele burden were investigated. JAK2 V617F was detected by allele specific PCR (Baxter et al, Lancet 2005). JAK2 V617F allele burden was quantified in granulocyte DNA by JAK2 Mutaquant kit (Qiagen). Blood parameters were obtained on routine hematologic analyzer Beckman Coulter DxH 800. High proportion of female patients was observed in all three groups that is not common in other MPN studies, particularly for diagnosis of PV and PMF. PV group presented with higher leucocyte and platelet count but lower hemoglobin concentration. ET is the most common MPN diagnosis in Croatian population with majority of female patients and laboratory findings similar to those observed in other studies. PMF patients are younger than those in other European countries and have higher blood cell counts. Results for V617F allele burden for all three groups are somewhat lower to those observed in JAK2 V617F positive MPN patients in Europe. In conclusion, MPN patients in Croatia showed some differences in laboratory findings in comparison with European JAK2 V617F positive MPN patients ; the reason for this could be the high proportion of female patients in our study.
