Impact of monocytes on Myeloproliferative Neoplasm hematopoietic stem cell growth and differentiation in vitro
The survival of children, adolescents and young adults (AYA) with acute leukemia has improved dramatically over the last two decades. This success is a result of using multiple chemotherapy drugs in combination, with the inclusion of drugs that enter the brain and prevent leukemia cells from growing there. Studies in these cancer survivors have shown that the exposure to these chemotherapy drugs can lead to risks for impaired brain function, also referred to as neurocognitive side effects of chemotherapy. There is an opportunity to identify participants at risk for these side effects and to prevent their development. The purpose of this study is to incorporate a brain imaging tool known as Magnetic Resonance Fingerprinting (MRF) to look for brain matter changes in acute leukemia participants receiving chemotherapy. The MRF scan will be performed at diagnosis and repeated at multiple times during the entire therapy duration as well as at defined intervals after therapy is complete. Investigators would also do an electronic test of memory and brain function (cognitive function), which would be administered in a gaming format on iPads or a similar device. The goal will be to correlate results of MRF imaging with the tests of cognitive function. The benefits of this imaging technique include that it can be done quickly (in minutes), it is non-invasive, it is resistant to motion-artifacts and it can be easily repeated for comparison purposes. The advantages of the cognitive test include its short duration of 20 minutes and its gaming format making it friendly for children to use.
Adult patients (>18 years) with newly diagnosis of Ph negative myeloproliferative neoplasms (MPNs) according to WHO 2016 criteria, will be recruited to this study. This study is the result of the collaboration the Hematology Division of Federico II University Medical School of Naples (Italy), that performed the US investigation and the IRCCS SYNLAB SDN where the patients carried out MR. The study is conducted in accordance with the Declaration of Helsinki. All subjects gave informed consent to receive both US and MR scans of the spleen. All spleen US scans were performed by the same operator (with>10 years of experience in abdominal US), who used an EPIQ 5 Philips instrument with a 1-5 MHz broadband curvilinear probe. The spleen was scanned in patients who were fasting, in the longitudinal and transverse planes by using an intercostal approach, a subcostal approach, or both. The patient was placed in a supine or right-sided position until complete organ visualization was achieved. Perimeter, longitudinal diameter (LD), and area, defined as the maximum measurements with splenic borders and angles clearly defined, were measured, and SV (in milliliters) was calculated automatically. For each subject, the mean value of 3 measurements repeated on the same imaging session was calculated and recorded for final analysis. Within two weeks from the US, each patient underwent an MRI of the upper abdomen to evaluate the splenic volume. MRI examinations were performed using a 3T Biograph mMR scanner (Siemens Healthcare, Erlangen, Germany) with 4-channel flex phased-array body coil. Routine clinical abdominal MRI acquisition includes coronal T2W Half-Fourier Acquisition Single-shot Turbo spin Echo imaging (HASTE), axial T1 Dual-echo FSE, axial T2 TSE Fat Sat, and an axial diffusion-weighted imaging (DWI). The DWI includes an apparent diffusion coefficient (ADC) map that was automatically generated at the time of acquisition. At last, an isotropic 2mm3 axial Volumetric Interpolated Breath-hold Examination (VIBE) sequence for SV evaluation was acquired. For the latter, attention was paid to optimize the field of view to the spleen, in order to reduce patient's apnea and possible respiratory artifacts. A radiologist with mote than 10 years of experience in abdominal MRI reporting performed measurement of the three orthogonal diameters of the spleen for each patient. Subsequently, SV was calculated using ITK-SNAP software and semi-automatic 3D segmentation approach, firstly based on a signal threshold.
Prospective study for functional and phenotypic characterization of monocytes in philadelphia-negative myeloproliferative neoplasms
The investigators will assess the use of a smart phone app to monitor patient reported outcomes and record biometric data in patients with myeloproliferative neoplasms.
This is a randomized, open-label, multicenter, two-arm study to assess the efficacy and safety of ropeginterferon alfa-2b for patients with low-risk PV. Approximately 110 patients with low-risk PV will be enrolled. The whole study period is 108 weeks, including a main treatment phase (56 weeks), an extension treatment phase (48 weeks), and a safety follow-up phase (four weeks).
The goal of Part 1 of this clinical research study is to find the highest tolerable dose of ASTX029 that can be given in combination with ASTX727 to participants who have RAS-mutant MDS or MDS/MPN. The goal of Part 2 of this clinical research study is to learn if the dose of ASTX029 found in Part 1 can help to control the disease when used in combination with ASTX727.
BCR:ABL1 negative myeloproliferative neoplasms (MPN) include three entities: polycythemia vera, essential thrombocythemia and primitive myelofibrosis. Myelofibrosis is a life-threatening complication in MPN with several therapeutic options including hematopoietic stem cell transplantation (HSCT) which remains the only curative treatment. Bone marrow biopsy with histological analysis allows myelofibrosis identification and staging. However, it is an invasive procedure that remains painful and provides potential haemorrhagic complications. Development of non-invasive biomarkers for myelofibrosis staging could help to better stratify this disease, better define patients' prognosis and lead to optimal cares. The main aim of this work is to develop a non-invasive blood score including several biomarkers for myelofibrosis staging in MPN using bone marrow biopsy as a gold standard.
Multicenter prevalence study of the PNH clone (paroxysmal hemoglobinuria nocturnal) in SMP Ph-. This multicenter, prospective study aims to evaluate the presence of an PNH clone in patients with a confirmed diagnosis of myeloproliferative neoplasia Phcon or without mutations in the 3 main genes involved in this disease (JAK2, MPL, and Cal-R),but showing signs of ongoing hemolysis or particular clinical conditions. To this end, a multicolor flow cytometric test will be used to evaluate the presence of deficient GPI molecules in granulocytic, monocytic and other cells erythrocyte (flow cytometric test, based on the use of the FLAER reagent in peripheral blood samples). The study will be conducted at clinical hematology centers in the wider area of the Romagna and at other Italian hematology clinical centers, where and analyzed the peripheral blood samples and clinical data to be included in the study. The participating centers will carry out the flow cytometric diagnostic test at i own reference laboratories, while the biological material for subsequent studies genetic-molecular type (next generation sequencing) will be analyzed centrally at the Biosciences laboratory of the IRST IRCCS only for cases testing positive for the presence of the PNH clone. Clinical information will be collected for each patient enrolled in the study necessary for the classification of the case and all the laboratory data necessary for achievement of the objectives of the study. The main objective of the study is to evaluate the prevalence of PNH clones in patients with a confirmed diagnosis of myeloproliferative neoplasm Ph- with or without mutations affecting the 3 main genes involved in this disease (JAK2, MPL, e Cal-R), but showing signs of ongoing hemolysis or particular clinical conditions. Secondary objectives of the study are: - correlate the characteristics of the PNH clone with the clinical characteristics and laboratory of myeloproliferative neoplasms Ph- (the presence of phenomena thrombotics, the disease state, the DIPSS prognostic score index, and the state mutational). · characterize the genomic architecture of the cases using NGS technology positive results
