Background: Myeloproliferative disorders (MPDs) are clonal hematologic malignancies originating at the level of the pluripotent hematopoietic stem cell. Matrix metalloproteases (MMPs) are proteolytic enzymes that contribute to all stages of malignancy progression. Genetic variants in the MMP genes may influence the biological function of these enzymes and change their role in carcinogenesis and progression. To our knowledge, this is the first investigation of associations between the -735 C/T and -1562 C/T polymorphisms in the MMP2 and MMP9 genes, respectively, and the risk of essential thrombocytosis (ET), and polycythemia vera (PV). Materials and Methods: The case-control study included JAK2V617F mutation positive 102 ET and PV patients and 111 controls. Polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and electrophoresis. Results: No statistically significant differences were detected between patient (ET+PV) and control groups regarding genotype distribution for MMP2 gene-735 C/T and MMP9 gene -1562 C/T polymorphisms and C/T allele frequency (p>0.050). Statistically borderline significance was observed between PV and control groups regarding genotype distribution for the MMP9 gene -1562 C/T polymorphism (p=0.050, OR=2.26, 95%Cl=0.99-5.16). Conclusions: Consequently this study supported that CC genotype of MMP9 gene -1562 C/T polymorphism may be related with PV even if with borderline significance.

Background: Invasive aspergillosis (IA)) is a serious cause of morbidity and mortality in immunocompromised patients with haematologic malignancy. The serum galactomannan enzyme immunoassay (GM-EIA; Platelia Aspergillus EIA; Bio-Rad) was cleared by the Food and Drug Administration at an optical density index cut-off of 0.5 for a probable diagnosis of invasive aspergillosis. In this prospective study GM-EIA (Platelia Aspergillus EIA, Bio-Rad) with 0.5cut-off value and sequential sensitivity-specificity for single, consecutive two and consecutive three positivity were investigated for the diagnosis of IA in neutropenic hematologic patients. Methods: Serum samples were taken twice a week from patients during their hospitalization. IA was classified according to European Organisation for Research and Treatment of Cancer and Mycoses Study Group Guidelines as “proven”, “probable”, and “possible”. The sensitivity was calculated from the results of patients with proven/propable and the specificity was calculated from the results of patients non-IPA patients. Results: In 165 consecutive febrile episodes in 106 patients, 80 (48.5%) episodes were defined with IA (4 proven, 11 probable, 65 possible) and 85 (51.5%) episodes were defined as non-IA. Per episode average 8.3 serum samples were examined for a total of 1385 serum samples. Cut-off value of single GM-EIA = 0.5 for proven/probable IA with sensitivity/specificity 100%/ 27%, two consecutive positive GM-EIA = 0.5 with sensitivity/specificity 86%/ 71% and three consecutive positive GM-EIA = 0.5 with sensitivity/specificity 73%/85% were obtained. Conclusions: Measuring the level of galactomannan twice a week and consecutive monitoring reduced the sensitivity and increased the specificity. Monitoring of the GM-EIA frequently from the first positivity can increase sensitivity/specificity.
