Seventy-three platelet crossmatches were performed for 69 patients, of which 30 patient samples (41%) showed crossmatch positivity. 25 (89.2%) of 28 unsuccessful transfusions showed crossmatch positivity, and 40 (88.9%) of 45 successful transfusions showed negative crossmatches (p = 0.03). Crossmatch positivity among transfusion dependent Paediatric Oncohaematology patients was as high as 42%, when ABO matched platelet units were allocated without further testing. Our results indicate that this test may be a reliable tool to select compatible platelet units and an effective intervention in the management of patients at risk of immune platelet refractoriness. © Indian Society of Hematology and Blood Transfusion 2019.Thawed fresh frozen plasma (FFP) if not used within 6 h, may have to be discarded due to the risk of contamination and uncertainty about its quality. The main objective of this study was to evaluate the levels of coagulation Factor II (FII), Factor VIII (FVIII), fibrinogen and bacterial growth in thawed refrozen FFP. Thirty FFP samples were collected from healthy donors. FFP were thawed in water bath at 37 °C for 20-25 min. Approximately 10 mL of plasma from each FFP unit was tested for FII, FVIII, fibrinogen and sterility. The thawed FFP units were then kept at 4 °C for 6 h before being refrozen and stored at - 20 °C. Two weeks later, the refrozen FFP were thawed again and representative samples were analysed as before. There was a significant decline in the mean FVIII level, from 155.77% to 85.6% at second thaw. The mean FII level increased significantly from 74.9% to 82%, whereas the mean fibrinogen level fell from 3.34g/L to 3.28 g/L, but the decline was not statistically significant. There was no bacterial contamination in all samples at both time points. Refrozen plasma may be considered as an alternative to the storage of thawed unused FFP provided they are kept in a controlled environment to reduce wastage. These thawed refrozen FFP can be used later in bleeding cases like other FFP as the levels of FVIII are still within the standard haematology range (0.5-2 IU/mL) and above the minimal level of 30% coagulation factors required for adequate haemostasis. © Indian Society of Hematology and Blood Transfusion 2019.Diffuse large B cell lymphoma (DLBCL) is the most common form of non-Hodgkin lymphoma among adults, although it also affects the young and the elderly. DLBCL is treated with a chimeric monoclonal antibody against CD20, a B cell surface protein, named rituximab, in combination with a multidrug chemotherapeutic regimen. However, owing to its high cost, rituximab cannot be afforded by patients in developing or underdeveloped countries. In such cases, biosimilars of rituximab have been used instead of rituximab, with equivalent efficacy. In this single center, retrospective, observational study, we have compared patient outcomes such complete response (CR), partial response (PR), and overall response rate (ORR) in a cohort of 152 patients in an Indian hospital, who were treated either with innovator rituximab or Reditux, a biosimilar. We observed that the ORRs of both groups (88% in innnovator group and 82% in biosimilar group) were comparable. Ropsacitinib supplier There was no statistically significant difference between the two groups in terms of CR (p = 0.353), PR (p = 0.42), ORR (p = 0.23), unfavorable responses, and stable or progressive disease (p = 0.42). The number of patients who died due to complications were few, and there was no significant difference between the two groups. The differences in the 3-year event-free survival and overall survival were not statistically significant. Biosimilar rituximab can suitably and safely replace the innovator rituximab for treatment of diffuse large B cell lymphoma. © Indian Society of Hematology and Blood Transfusion 2019.Patients with hematological malignancies are severely immunocompromised and are at high risk of invasive fungal infection (IFI), particularly those undergoing remission-induction chemotherapy for acute myeloid leukemia (AML). IFIs are a major cause of morbidity and mortality in such patients. We planned to study the incidence of IFI in patients with AML undergoing intensive chemotherapy and receiving antifungal prophylaxis. We retrospectively reviewed consecutive 46 patients with non-M3 AML, who received induction chemotherapy and systemic antifungal prophylaxis. None of the patients had IFI at the time of initiation of the chemotherapy. Patients were monitored for the occurrence of IFI using high-resolution computerized tomography of the chest or para-nasal sinus and test for galactomannan antigen on serum or broncho-alveolar lavage and were followed up for 90 days. Of the 46 patients on intensive chemotherapies, 41, 4 and 1 patients were started on posaconazole, amphotericin B and voriconazole prophylaxis, respectively. The occurrence of possible and probable IFI was observed in 16 and 4 patients respectively, in which 19 patients were on posaconazole and 1 patient was on amphotericin-B prophylaxis. Overall mortality in the study population was 11 (23.9%). Four out of 20 patients died with IFI but none of the death was attributable to IFI. IFI still remains a significant cause of morbidity and mortality in patients with AML despite universal use of antifungal prophylaxis. With effective pharmacotherapy, the mortality due to IFI is preventable. Appropriate antifungal prophylaxis strategy still needs to be developed through larger and prospective studies. © Indian Society of Hematology and Blood Transfusion 2019.Methotrexate (MTX) is an extensively prescribed antimetabolite especially in the treatment of several pediatric cancers, though managing toxicities associated with methotrexate in high dose continues to be a challenge. A prospective study was carried out from April 2017 to October 2018. Children of either sex below 18 years at the time of enrolment and receiving high dose Methotrexate intravenous infusion over 24 h as a 2 g/m2, 3 g/m2 and 5 g/m2 dose was included in the study. The serum methotrexate level was estimated after the start of 48 h HDMTX infusion by using the ARCHITECT methotrexate assay. Toxicity due to HDMTX was assessed by Common Terminology Criteria for Adverse Events v.5.0. A total of 244 HDMTX infusions were delivered to 62 ALL patients. From the total of 244 cycles, serum methotrexate level in 35 cycles after the start of 48 h HDMTX infusion was found to be ≥ 1.0 μmol/L with reported toxicities among 31 cycles (88.6%). In 209 cycles MTX level was found to be less than 1.0 is statistically significant as compared to other cycles (p  less then  0.0001). Highest toxicities reported were in cycle I (38.8%). The toxicities such as oral mucositis, neutropenia, the elevation of liver enzymes, dermatological toxicities were found more in cycles whose methotrexate level are greater than 1.0 μmol/L. Dose reduction, increased the length of stay and treatment delay occurred in patients with severe toxicities. Severe toxicities of methotrexate can be interrelated with serum methotrexate levels at 48 h after the start of HDMTX infusion. © Indian Society of Hematology and Blood Transfusion 2019.The median age of diagnosis for chronic myeloid leukemia (CML) in India is 35 years on the contrary to western literature which is 47 years. link2 The outcome of the elderly patient in CML TKI era is not reported from the Indian population. However, Western literature suggests that use of TKI alleviate the adverse impact of age in outcomes of CML. This study was carried out to analyze the clinical profile and outcome of elderly, in comparison with younger patients with CML. We retrospectively analyzed CML patients treated at our department from January 2008 to December 2017. The data cutoff date was December 2018. link3 The cohorts of 712 patients were divided into two groups. Patients belonging to the age group of ≥ 60 years were classified as the study group and those who were 18-60 years were used as controls. Patient's clinical history, examination and milestones in terms of achieving hematological, molecular responses and toxicity profile were also recorded. The total of 712 patients, 52 patients in the study group and 660 patients in the control group were treated during the study period. The study group was having more co-morbidities than the control group (15.3% vs. 4.5%). Patients having high-risk EUTOS score were similar in both groups (38.4% vs. 37.6%). The patients presented in blast phase were higher in the study group as compared to control group (9.6% vs. 6.36%) but the differences were not statistically significant. Rates of achieving a hematological response at 3 months (85.1% vs. 86.89%) and the major molecular response at 18 months (54.3% vs. 60.16%) were almost similar in both groups. However, hematological toxicity, muscle cramps and gastritis were reported more in elderly patients. The outcome of CML patients in TKI era do not differ in elderly patients. However, toxicity profile was not significantly inferior in elderly patients. © Indian Society of Hematology and Blood Transfusion 2019.Erythropoietin (EPO) is an important hormone responsible for the stimulation of hematopoiesis which is impaired in a variety of diseases, such as chronic kidney disease, cancer chemotherapy, and the use of some anti-HIV drugs. Difficulties in the purification of endogenous EPO due to problems such as technical limitations, heterogeneity of target cells, inadequate amount and immunogenicity of the resultant product, had limited the entry of endogenous EPO in the clinical applications. The integration of medical biotechnology and hematology has introduced novel procedures for the production of human recombinant erythropoietin (rHuEPO), and other erythropoiesis-stimulating agents (ESAs). To investigate and produce rHuEPO, the first step is to recognize the molecular biology and functional pathways, structure, metabolism, and basic physiology of EPO. In this review, all clinical indications, side effects, challenges and notable points regarding EPO, rHuEPO, and other ESAs have also been addressed along with its molecular characterization, such as the modifications needed to optimize their rHuEPO biosynthesis. © Indian Society of Hematology and Blood Transfusion 2019.Minimal residual disease (MRD) analysis for patients of acute leukemia has evolved as a significant prognostic factor. Based on the MRD results, the cases are risk-stratified after induction chemotherapy, and an alteration in further management is made to yield maximal therapeutic benefits. The two primary methodologies for MRD detection are multi-parameter flow cytometry (MFC) and polymerase chain reaction. MFC identifies the MRD based on characteristic 'leukemia-associated immunophenotypes' on the residual leukemia cells. MRD analysis by MFC is most frequently done at the post-induction stage of treatment and often can achieve a sensitivity of detecting one leukemic cell in 10,000 normal cells, or even higher at times. This review outlines the technical aspects and provides inputs on standard antibody panels used for MRD detection in B-, T-lineage acute lymphoblastic leukemias, and acute myeloid leukemia. © Indian Society of Hematology and Blood Transfusion 2019.
