5% children were moderate and 54.8% children were of severe type. In our study there was no significant correlation between severity of the disease and HbF level (r = 0.0853, p = 0.0509). Age at the time of diagnosis, hemoglobin level at the time of first transfusion, age at receiving first blood transfusion, requirement of blood transfusion, spleen size and growth, are some factors affecting severity of the disease. But severity cannot be assessed by considering only one clinical or hematological parameter but by considering several parameters together. © Indian Society of Hematology and Blood Transfusion 2019.To describe the health-related quality of life (HRQoL) and fatigue burden among adult patients with immune thrombocytopenia (ITP) in China and determine whether they vary with disease phase. This is a cross-sectional, multi-centre observational study of adult ITP patients and the general population. Participants completed the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). We compared HRQoL and fatigue between ITP patients and the general population, overall and by disease phase (newly diagnosed, persistent, and chronic), using propensity score matching. 203 Patients and 269 members of the general population were recruited. Thirty-six ITP patients (17.7%) were newly diagnosed, 46 (22.7%) were persistent, and 121 (59.6%) were chronic. Compared with the general population, ITP patients had impaired HRQoL and greater fatigue burden. The persistent ITP group showed the largest number of SF-36 scales exceeding the minimally important difference physical functioning [- 10.5; 95% confidence interval (CI) - 24.5 to 3.5; P  less then  0.001], role physical (- 16.7; 95% CI - 36.4 to 3.0; P  less then  0.001), social functioning (- 15.6; 95% CI - 34.5 to 3.3; P  less then  0.001), and role emotional (- 12.1; 95% CI - 26.0 to 1.8; P  less then  0.001). Chronic ITP patients had the worst FACIT-F scores (36.89 ± 5.21). Higher fatigue severity was associated with lower physical and mental HRQoL. The HRQoL and fatigue burden of Chinese adult patients with ITP vary by disease phase. Persistent ITP patients were the most vulnerable subgroup in terms of HRQoL, while chronic ITP patients bear the heaviest fatigue burden. © Indian Society of Hematology and Blood Transfusion 2019.We performed a prospective multi-centre observational study to understand the incidence of IFI in patients with AML in India with use of anti-fungal prophylaxis. All patients with AML receiving either induction chemotherapy or salvage chemotherapy between November 2014 and February 2016 were included in this prospective observational study from 10 Indian centres. IFI was defined as per the revised EORTC-MSG criteria. Data on type of chemotherapy used, type of anti-fungal prophylaxis used, time to neutrophil recovery, incidence of IFI and survival were collected. Two hundred patients (118 male and 82 females) with a median age of 35 years (range 2-66) were recruited. One hundred and eighty-six (93%) had newly diagnosed acute myeloid leukemia (AML) while 14 (7%) had relapsed disease. IFI occurred in 53 patients (26.5%) with proven or probable IFI occurring in 17 (8.5%). Use of posaconazole prophylaxis (p = 0.027) was the only factor found to be associated with a reduced incidence of IFI. The overall survival (OS) at 6 weeks and 3 months respectively was similar among patients who had IFI (83.0 ± 5.2%; 81.0 ± 5.4%) as compared to those without IFI (84.4 + 3.0%; 81.4 ± 3.2%). This prospective study reveals a high incidence of IFI in patients undergoing chemotherapy for AML in India. The use of posaconazole prophylaxis was associated with a significantly lower incidence of IFI. Optimal strategies to prevent IFI need to be studied. © Indian Society of Hematology and Blood Transfusion 2019.Acute myelogenous leukemia (AML) is a heterogeneous disease characterized by myeloid progenitor cells uncontrolled proliferation gradually replacing normal hematopoiesis. To evaluate Ten Eleven Translocation 2 gene (TET2) single nucleotide polymorphism (SNP) (rs2454206, rs34402524, rs61744960) in AML, and chronic myeloid leukemia (CML) in relation to their disease prognostic criteria. The study included 136 subjects; 52 AML, 54 CML and 30 subjects as control group matched for age and sex. Routine investigations including CBC, bone marrow aspiration, flow cytometry biochemical investigations and cytogenetics and molecular study were performed accordingly.  https://www.selleckchem.com/products/mrtx0902.html  DNA extraction and SNP assay for TET2 gene polymorphism was done using (Thermo-Fisher predesigned SNP, USA) PCR prism 7500. The mean age was 43.4 ± 14.0 years in AML patients, 45.98 ± 15.7 years in CML patients and 39.3 ± 6.587 years in control group (p > 0.05). The frequency of TET2 SNP rs 34402524 ranged from heterozygous to homozygous in both AML (46%, 54%leukemogenesis transformation. © Indian Society of Hematology and Blood Transfusion 2019.Chronic lymphocytic leukemia (CLL) is a common hematological malignancy. This study is aimed to investigate the prognostic effect of clinic, laboratory and flow cytometric analysis in CLL patients. Newly diagnosed 55 CLL cases were divided into two groups, as stable disease (Group 1) and progressive disease (Group 2). Group 1 included those who did not require any treatment since diagnosis and those who did not progress after receiving the first step anti CLL treatment. Group 2 included the patients who received ≥ 2 steps treatment. The relation between the two groups was analyzed statistically in terms of clinical, laboratory and flow cytometric findings. Twenty patients (36.3%) required treatment at the time of diagnosis, four patients (3.8%) received first-line treatment during follow-up and 31 (56.3%) patients were followed without any treatment. Thirteen patients required second step treatment after a median of 26.3 months. The risk of progression was found to be increased 5-fold (p = 0.015) in the CD38 positive patient group, 4.
