Abstract
Introduction Allogeneic hematopoietic stem cell transplantation (HSCT) is currently the only curative treatment option for myelofibrosis (MF). Despite the benefits of long-term relapse-free survival, HSCT can be associated with substantial treatment-related morbidity and mortality. Methods This is an observational retrospective study of 15 consecutive patients with MF who underwent allogeneic HSCT at a tertiary care center in Northern India between June 2012 and January 2020. The pre-transplant Dynamic International Prognostic Scoring System (DIPSS) and hematopoietic cell transplantation-specific co-morbidity index (HCT-CI) scores were used. The primary endpoints were overall survival (OS) and disease-free survival (DFS), and the secondary endpoints were post-transplant complications (acute and chronic graft-versus-host-disease [GvHD], graft failure [GF], and cytomegalovirus reactivation [CMV]). Results The OS and DFS in our study were 60% with no relapse at a median follow-up of 364 days (range 7-2,815 days). Twenty-seven percent of patients developed acute GvHD and 27% of patients developed chronic (limited) GvHD. The non-relapse mortality (NRM) was 40%, with the main cause of death being sepsis, followed by acute GvHD. Conclusion MF remains a challenging condition to treat, with a poor prognosis. Our study showed that reduced toxicity conditioning provided good DFS and OS. Thus, it should be offered to patients with high DIPSS scores. Sepsis was the predominant cause of mortality in this cohort.

Abstract
Background: FxCycleTM Violet (FCV) based flow cytometric (FCM) DNA ploidy analysis is a rapid and simple tool that can substantiate in characterizing the biological behaviour across the spectrum of haematological malignancies and correlates with cytogenetic studies. Materials and Methods: In this prospective study, we performed simultaneous immunophenotyping with FCV based on ploidy analysis in n=132 consecutive new samples, comprising n=110 samples of haemato-lymphoid neoplasms, including acute leukemias (n=67, 60.9%), CML with myeloid blast crisis (n=1, 0.9%), MDS with excess blasts (n=2, 1.8%), mature B cell/ T cell neoplasms (n=37, 33.7%), multiple myeloma (n=3, 2.7%) along with n=22 normal samples. The FCM DNA data was compared with corresponding conventional karyotyping results, wherever available. Results: In FCM ploidy analysis (n=110), the overall DNA index (DI) ranged from 0.81 to 2.17 and S-Phase fraction (SPF) from 0.1-31.6%. Diploidy was seen in n = 90 (81.8%), low-hyperdiploidy in n = 10 (9.1%), high-hyperdiploidy in n = 7 (6.4%) with one case each (0.9% each) having near-tetraploidy, high-hypodiploidy and low-hypodiploidy. The DI of all viable cell populations in normal samples ranged from 0.96-1.05. Conventional karyotyping was performed in n=76/110 cases (70%) with n= 11/76 (15%) culture failures. The modal chromosome number ranged from 45 to 63. A concordance of 95.4% (n=62/65) was noted with corresponding FCM DI. Conclusion: FCV-based ploidy is a sensitive technique that provides complementary information and ascertains a strong correlation with conventional cytogenetics across all haemato-lymphoid neoplasms. It can detect aneuploidy in all B-ALL and myeloma cases, even in hemodiluted samples with cytogenetic culture failure; supplement the diagnoses of erythroleukemia, and provide a useful screen for a higher grade lymph node disease in lymphoma cases with SPF > 3%.

Abstract
Hematopoietic stem cell transplantation (HSCT) is the preferred treatment for high-risk and relapsed/refractory hematological malignancies. Moreover, with the improved supportive care and increasing acceptance of haploidentical transplantations as an alternative treatment modality, more patients are opting for HSCT as a definite treatment for hematological malignancies. We report here the real-world data and outcome of HSCT done for hematological malignancies at our transplant center. Five hundred and sixteen patients underwent HSCT from August 2010 to November 2019. The most common indications for allogeneic and autologous HSCT were acute myeloid leukemia and multiple myeloma, respectively. The 5-year overall survival and disease-free survival for all transplants were 65% and 33%, respectively. Though outcome of matched sibling donor allogeneic transplant is better than haploidentical donor (HID) transplant, patients having only HID can still be considered for allogeneic HSCT for high-risk diseases. The most common cause of death was infections followed by relapse of the disease.

Abstract
COVID-19, caused by the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), was declared a pandemic by the World Health Organization on March 9, 2020. Hematopoietic stem-cell transplantation (HSCT) recipients may be highly susceptible to infection and related pulmonary complications due to nascent immune systems or organ damage from treatment-related toxicities. Poor outcomes in such group of patients were linked to older age, steroid therapy at the time of COVID-19 infection, and COVID-19 infection within a year of HSCT. We studied a cohort of 28 hematopoietic stem cell transplant recipients (male 17, M:F ratio of 1.5) with COVID-19 infection from 1st June 2020, through 31st December 2020 for outcome. Fever was the most common symptom at the time of presentation in 22 (78.5%) patients. Mortality rate at Day 28 and Day 42 was found to be 4/28 (14.3%) and 7/28 (25%) respectively. Patients within one year of HSCT and severe infection had higher day 28 mortality (with p values = 0.038)". There was no relation of mortality with type of transplant.

Abstract
BACKGROUND There is scarcity of data on outcome of COVID-19 in patients with hematological malignancies. Primary objective of study was to analyse the 14-day and 28-day mortality. Secondary objectives were to correlate age, comorbidities and remission status with outcome. METHODS Retrospective multicentre observational study conducted in 11 centres across India. Total 130 patients with hematological malignancies and COVID-19 were enrolled. RESULTS Fever and cough were commonest presentation. Eleven percent patients were incidentally detected. Median age of our cohort was 49.5 years. Most of our patients had a lymphoid malignancy (n = 91). One-half patients (52%) had mild infection, while moderate and severe infections contributed to one-fourth each. Sixty seven patients (52%) needed oxygen For treatment of COVID-19 infection, half(n = 66) received antivirals. Median time to RT-PCR COVID-19 negativity was 17 days (7-49 days). Nearly three-fourth (n = 95) of our patients were on anticancer treatment at time of infection, of which nearly two-third (n = 59;64%) had a delay in chemotherapy. Overall, 20% (n = 26) patients succumbed. 14-day survival and 28-day survival for whole cohort was 85.4% and 80%, respectively. One patient succumbed outside the study period on day 39. Importantly, death rate at 1 month was 50% and 60% in relapse/refractory and severe disease cohorts, respectively. Elderly patients(age ≥ 60) (p = 0.009), and severe COVID-19 infection (p = 0.000) had a poor 14-day survival. The 28-day survival was significantly better for patients in remission (p = 0.04), non-severe infection (p = 0.00), and age < 60 years (p = 0.05). CONCLUSIONS Elderly patients with hematological malignancy and severe covid-19 have worst outcomes specially when disease is not in remission.

Abstract
The conditioning regimens used for the allo-HSCT include either myeloablative conditioning (MAC) or reduced intensity conditioning (RIC) regimens based on the age, performance status and co-morbidities. Studies comparing the survival outcomes of RIC and MAC allo-HSCT in AML and MDS patients have reported contradictory results. We therefore retrospectively analyzed our data of AML and MDS patients who received MAC and RIC allo-HSCT at our center and compared the long term outcome of the two conditioning regimens. One hundred twenty six consecutive patients were evaluated, 32 (25.4%) underwent MAC allo-HSCT and 94 (74.6%) underwent RIC allo-HSCT. The most common MAC regimen used was busulfan plus cyclophosphamide and the most common RIC regimen used was fludarabine plus melphalan. The median age was higher in RIC group (44 years, range 4-75 years) compared to MAC group (31 yrs, range 6-51 yrs, p = 0.001). There was no significant difference in terms of overall survival (p = 0.498), relapse-free survival (p = 0.791) and non-relapse mortality (p = 0.366) between the two groups. In multivariate analysis, only chronic graft-versus-host disease resulted in decreased risk of relapse and improved overall survival irrespective of the conditioning regimens used.

Abstract
INTRODUCTION Granulocyte-colony stimulating factor (G-CSF) has been approved for use for mobilization of hematopoietic progenitor cells from the marrow into the blood for peripheral blood stem cell collection. Commonly reported side effects of G-CSF include deep throbbing bone pain, severe myalgia and leucocytosis. CASE REPORT We describe a case of severe hypersensitivity anaphylactoid reaction after filgrastim administration in a healthy stem cell donor. This haploidentical donor was a 38-year old man with sickle cell trait, donating stem cells for his son, a case of sickle cell disease. On administration of G-CSF (10 µg/kg) he developed features of anaphylaxis. MANAGEMENT AND OUTCOME He was given supportive care with oxygen, IV fluid bolus, anti histaminics and steroids. The donor had complete recovery and underwent successful bone marrow harvest. CONCLUSION There have been various reports of hypersensitivity anaphylactoid reactions in patients undergoing chemotherapy but those associated with the first dose of G-CSF in healthy stem cell donors have rarely been reported.

Abstract
Cytarabine, a pyramidine analog, is used for treating various hematological malignancies such as acute leukemias and lymphomas. Side effects of cytarabine are dose dependent and include bone marrow suppression, fever, cerebellar toxicity, cardiomyopathy, hepato-renal insufficiency, necrotizing enterocolitis, pancreatitis, acute respiratory distress, corneal toxicity and dermatological side effects. The dermatological side effects can be immediate or due to delayed hypersensitivity reactions. They have been attributed largely to release of cytokines. We present three such cases of delayed hypersensitivity to cytarabine affecting the ears bilaterally.

Abstract
Graft-versus-host disease (GVHD) is the major complication post hematopoeitic stem cell transplantation (HSCT) causing significant morbidity and mortality. Colonic biopsies were performed in 25 post HSCT patients presenting the diarrhea for diagnosis of acute graft versus host disease (A-GVHD). The present study was undertaken to evaluate and illustrate histomorphological features of A-GVHD in GI biopsies and to grade them. Histopathological features of gastrointestinal biopsies from 25 allogeneic HSCT patients having clinical suspicion of A-GVHD were evaluated and compared with colonic biopsies from negative controls. A-GVHD was observed in 17 cases, CMV colitis was present in 3 cases and one case had herpes simplex infection diagnosed in conjunction with serological findings. A-GVHD was graded as grade 1 and 2 in 10 cases and grade 3 and 4 in 7 cases. Apoptosis of crypt epithelial cells was the cardinal feature for diagnosis. Grade 1 and grade 2 A-GVHD cases showed crypt apoptosis in all cases as well as pericryptal apoptosis in lamina propria in many cases. Occasional crypt loss was seen in grade 2 GVHD. Inflammatory infiltrate was composed of lymphocytes and plasma cells. Neutrophils were inconspicuous. Grade 3 and grade 4 A-GVHD cases showed contiguous areas of multiple crypt loss and ulceration with inflammatory infiltrate predominantly composed of lymphocytes and plasma cells, but neutrophils were more prominent than in grade 1 and 2 A-GVHD. Apoptosis of crypt epithelial cells was present in all grade 3 &4 cases except one case. CMV cases were diagnosed by CMV inclusions and IHC stain. Several factors including drug-induced side effects and infections can cause difficulty in histologic interpretation of gastrointestinal biopsies for GVHD. Proper histomorphological interpretation of intestinal A-GVHD is critical for clinical management. A-GVHD is treated with immunosuppression which may worsen infective condition, if present.

Abstract
BACKGROUND AND OBJECTIVE: Controlled-rate freezing is a complicated, expensive, and time-consuming procedure. Therefore, there is a growing interest in uncontrolled-rate freezing (UCF) with −80°C mechanical freezers for cryopreservation of hematopoietic stem cells. This is a retrospective analysis of efficiency of UCF and outcome of autologous peripheral hematopoietic stem cell (PBSC) transplants at our center from December 2011 to June 2016. MATERIALS AND METHODS: Cryoprotectant solutions used included 5% dimethyl sulfoxide and 5% albumin with 2% hydroxyethyl starch and stored at −80°C mechanical freezer till transplant. Evaluation of cryopreservation was studied by analyzing the variation in cellularity, viability, and CD34+ stem cell dose recovery as well as clinical follow-up with engraftment. RESULTS: A total of 51 patients (23 females and 28 males) underwent autologous PBSC transplantations with a median age of 31 years (range: 3–60 years) for both hematological and nonhematological indications. Mean recovery post by UCF at −80°C mechanical was 92.9% ± 15.5% for nucleated cells, 86.6% ± 15.5% for viability, and 80% ± 21.5% in CD34+ dose. The median day to neutrophil engraftment was 10 (range 5–14 days) and platelets engraftment was 15 (range 8–45 days). The cryopreserved products were stored at −80°C for median 7 days (range 2-41 day) before transplant. DISCUSSION/CONCLUSION: Our analysis shows that PBSC can be successfully cryopreserved with mechanical uncontrolled rate freezing. This is a cheap and simple method to freeze the stem cells for a short period in resource-constrained setting.

Abstract
Many countries have observed an increase in the incidence of invasive fungal infections (IFIs) over the past two decades with emergence of new risk factors and isolation of new fungal pathogens. Early diagnosis and appropriate antifungal treatment remain the cornerstones of successful outcomes. However, due to non-specific clinical presentations and limited availability of rapid diagnostic tests, in more than half of cases antifungal treatment is inappropriate. As a result, the emergence of antifungal resistance both in yeasts and mycelial fungi is becoming increasingly common. The Delhi Chapter of the Indian Association of Medical Microbiologists (IAMM-DC) organized a 1 day workshop in collaboration with BSAC on 10 December 2015 in New Delhi to design a road map towards the development of a robust antifungal stewardship programme in the context of conditions in India. The workshop aimed at developing a road map for optimizing better outcomes in patients with IFIs while minimizing unintended consequences of antifungal use, ultimately leading to reduced healthcare costs and prevention development of resistance to antifungals. The workshop was a conclave of all stakeholders, eminent experts from India and the UK, including clinical microbiologists, critical care specialists and infectious disease physicians. Various issues in managing IFIs were discussed, including epidemiology, diagnostic and therapeutic algorithms in different healthcare settings. At the end of the deliberations, a consensus opinion and key messages were formulated, outlining a step-by-step approach to tackling the growing incidence of IFIs and antifungal resistance, particularly in the Indian scenario.

Abstract
BACKGROUND Furanone and pyrrolone heterocyclic ring system represent important and interesting classes of bioactive compounds. Medicinal chemists use these heterocycyclic moieties as scaffolds in drug design and discovery. METHODS A series of 3-arylidene-5-(naphthalene-2-yl)-furan-2(3H)-ones (2a-j) were synthesized by incorporating pharmacophore of COX-2 inhibitor rofecoxib and naphthyl ring of naproxen as potential non steroidal anti-inflammatory agents. These furanone derivatives were subsequently reacted with dry ammonia gas and benzylamine to furnish corresponding 3-arylidene-5-(naphthlen-2-yl)-1H-pyrrol-2(3H)-ones (3a-e) and 3-arylidene-1-benzyl-5- (naphthalene-2-yl)-1H-pyrrol-2(3H)-ones (4a-e), respectively. The newly prepared heterocyclics were screened for their expected in-vivo biological activities including anti-inflammatory, analgesic and ulcerogenic actions in rodents. The COX-2 inhibitory behavior of synthesized compounds was also assessed via automated docking studies. RESULTS The chemical structure of the synthesized compounds was characterized by using modern spectroscopic techniques. Result of in-vivo pharmacological studies demonstrated that almost all N-Benzyl-pyrrol-2(3H)-ones (4a-e) showed better anti-inflammatory and analgesic activities in comparison with the other two series of furan-2(3H)-ones and pyrrol- 2(3H)-ones. The moldock score value of the tested compounds was found in the range of -116.66 to -170.328 and was better than the standard drug. CONCLUSION Among all the synthesized compounds, only nine compounds (2d, 2g, 2h, 3d, 4a, 4b, 4c, 4d and 4e) exhibited potent anti-inflammatory and analgesic activities with significantly reduced gastrointestinal toxicity in various animal models in comparison to standard drug, diclofenac. Therefore, it is recommended to explore the potential of the synthesized compounds as lead candidates for the development of new therapeutic agents.

Abstract
Juvenile myelomonocytic leukemia (JMML) and chronic myelomonocytic leukemia (CMML) are myelodysplastic/myeloproliferative neoplasms associated with poor prognosis. There is no definitive treatment for such patients other than stem cell transplantation, and chemotherapy is not much effective. Timely diagnosis and early referral to the transplant centre is important for the management of these diseases. We report here a case of JMML and another case of CMML who were treated successfully with peripheral blood stem cell transplantation.

Abstract
Cytogenetic abnormalities are the hallmark of leukemias. We report here two cases of unusual cytogenetic abnormalities associated with Philadelphia chromosome, one with mixed phenotypic acute leukemia showing monosomy 7 and t(9;22) (q34;q11.2) and the other with chronic myeloid leukemia and additional translocation involving chromosomes 10 and 13. Both patients achieved complete remission following imatinib based treatment.

Abstract
Mucositis is a known complication following use of chemotherapy, but fatal mucositis is unusual and management of such cases may be challenging. Pathologically there is denudation of mucosa of gastrointestinal tract. Severe cases can develop ileus and even perforation of bowel wall. We report here a case of multiple myeloma who developed World Health Organization grade 4 gut mucositis following the use of high dose melphalan with the expulsion of “intestine-like” material.

Abstract
The association of CYP1B1 gene alterations in primary congenital glaucoma individuals has been known for about a decade. Recent evidence has shown the involvement of CYP1B1 mutations in a number of forms of glaucoma and anterior segment disorders. This suggests a wide role for CYP1B1 in ocular physiology. Histochemical studies of eyes from individuals with primary congenital glaucoma revealed abnormalities in the anterior chamber angle, the region between the cornea and the iris, containing the trabecular meshwork. The cells of the trabecular meshwork serve as a filter to allow drainage of the aqueous humour, the fluid formed by the ciliary body that fills the anterior chamber. Mutations in CYP1B1 that affect its activity have frequently been shown to influence development of the trabecular meshwork, and it is thought that CYP1B1, a monooxygenase, acts to form or degrade some endobiotic compound that is necessary for proper development of the filtering structures. The rapidly developing area of stem cell research suggests a potential therapeutic approach for glaucomas resulting from deleterious mutations in CYP1B1, that is, the transfer of stem cells, differentiated to a specific lineage, containing wild-type CYP1B1 to specific regions of the eye, where they will develop into normal cells of that region and rectify the defect.

Abstract
Expression of 10 CYP orthologs (Families 1-3) in developing mouse conceptus is constitutive. These forms have specific temporal and spatial expression. Studies on CYP1B1 indicate its requirement for normal eye development, both in human and mouse. The distribution of the enzyme in the mouse eye is in three regions, which may reflect three different, perhaps equally important, functions in this organ. Its presence in the inner ciliary and lens epithelia appears to be necessary for normal development of the trabecular meshwork and its function in regulating intraocular pressure. Its expression in the retinal ganglion and inner nuclear layers may reflect a role in maintenance of the visual cycle. Its expression in the corneal epithelium may indicate a function in metabolism of environmental xenobiotics.

Abstract
This study is the first systematic investigation of the gestational age-dependent and adult tissue-specific expression patterns of each known mouse CYP family (40 genes) using normalized cDNA panels and uniform reverse transcriptase polymerase chain reaction-based assays. Twenty-seven of the P450s were constitutively expressed during development. The number gradually increased through the phases of gastrulation E7 (n=14), neural patterning and somitogenesis E11 (n=17), organogenesis E15 (n=20), and fetal period E17 (n=21). Cyp2s1, Cyp8a1, Cyp20, Cyp21a1, Cyp26a1, Cyp46, and Cyp51 were detected in each of the four stages studied. Members of family CYP1 demonstrated complex, nonoverlapping embryonic patterns of expression, indicating that Cyp1a1 and Cyp1a2 may not compensate for Cyp1b1 deficiency associated with abnormal eye development. Multiple Cyp forms were found to be constitutively expressed in each of the adult tissues studied: liver (n=31), kidney (n=30), testis (n=26), lung (n=24), and heart (n=13). The tissue-specific P450-expression profiles reported in this study provide a reference for more focused analysis of the tissue-specific and developmental functions of the cytochrome P450 monooxygenases.

Abstract
There is a growing interest in understanding the biological effect of time-tested folk medicinal plants. In the present work, the effect of dietary administration of fenugreek seeds on the glyoxalase system and antioxidant enzymes as well as levels of glutathione (GSH) have been examined in different tissues of mice. Swiss albino mice were fed with diet containing powdered fenugreek for 4 weeks. The mode and magnitude of effect was found to depend on the dose of fenugreek and type of tissue. The diet containing 1 and 2% of fenugreek enhanced the specific activity of gly I, whereas 5 and 10% inhibited its activity in the liver. However, on the other hand, the specific activity of gly II decreased continuously with dose. Dietary administration of fenugreek seeds resulted in an increase of GSH levels and the glutathione S-transferase (GST) activity in the liver. Fenugreek (1 and 2%) showed no appreciable change in superoxide dismutase (SOD) and catalase. However, 5 and 10% doses of fenugreek supplementation inhibited their activities. In the case of spleen, a significant change in gly I was observed only at 10% fenugreek. In addition, a significant increase was also observed with GSH levels. Fenugreek treatment up to 5% showed a small but consistent increase in erythrocytes. In the case of GST, the activity enhanced with dose. Significant elevation of catalase activity was observed with a 10% dose of fenugreek. The significance and relevance of these findings are suggested in relation to mechanistic aspects.

Abstract
Understanding the response of tumors to ionizing radiation might potentially lead to improvement in tumor control and patient morbidity. Since the antioxidant status is likely to be linked to radioresponse, its modulation needs to be examined. Therefore, Swiss albino male mice (7-8 weeks old) with Ehrlich solid tumors were irradiated with different doses of gamma rays (0-9 Gy) at a dose rate of 0.0153 Gy/s; and enzymes involved in antioxidant functions were determined in the tumors. Radiation effects in terms of oxidative damage, LDH, nitric oxide and DNA fragmentation were also examined. In tumors, the specific activity of SOD was increased with dose but declined 6 Gy onwards. GST, DTD and GSH showed an almost progressive increase. These enhanced activities might have resulted from the increased protein expression. This possibility was supported by the Western Blot analysis for GST protein. These changes might be closely linked to the radiation-induced oxidative stress as reflected by the enhanced levels of peroxidative damage, DNA fragmentation, LDH activity and nitric oxide levels. These findings may have relevance to radiation therapy of cancer as the elevated antioxidant status of irradiated tumors is likely to limit the effectiveness of radiation dose and adversely affect the therapeutic gain.

Abstract
Human beings have been exposed to radiation for many years. It is quite possible that antioxidant phytochemicals consumed in their diet might be providing a variable degree of radioprotection. However, their radiomodifying ability is not well understood. In the present work, curcumin (diferuloyl methane), a phytochemical present in the rhizome of Curcuma longa Linn. has been examined for its radioprotective property using the glyoxalase system which is vital for various biological functions. Curcumin (5, 25 and 50 mg/kg body weight) in olive oil was given orally to Swiss albino male mice (7-8 weeks old) daily for 2 weeks and irradiated with different doses of gamma-radiation (0-6 Gy) at 0.027 Gy per second dose rate on last day of the treatment. The specific activities of glyoxalase I and II were determined in the liver and spleen. The treatment of curcumin prior to irradiation restored the specific activity of glyoxalase system to almost the control level which was suggestive of the radioprotective ability of curcumin. Free radical scavenging and electron/hydrogen donation are probable attributes for the protective effect of curcumin.

Abstract
Cellular membranes are vital elements, and their integrity is extremely essential for the viability of the cells. We studied the effects of high linear energy transfer (LET) radiation on the membranes. Rabbit erythrocytes (1 x 10(7) cells/ml) and microsomes (0.6 mg protein/ml) prepared from liver of rats were irradiated with 7Li ions of energy 6.42 MeV/u and 16O ions of energy 4.25 MeV/u having maximum LET values of 354 keV/microm and 1130 keV/microm, respectively. 7Li- and 16O-induced microsomal lipid peroxidation was found to increase with fluence. The 16O ions were more effective than 7Li ions, which could be due to the denser energy distribution in the track and the yield of free radicals. These findings suggested that the biological membranes could be peroxidized on exposure to high-LET radiation. Inhibition of the lipid peroxidation was observed in the presence of a membrane-active drug, chlorpromazine (CPZ), which could be due to scavenging of free radicals (mainly HO* and ROO*), electron donation, and hydrogen transfer reactions. The 7Li and 16O ions also induced hemolysis in erythrocytes. The extent of hemolysis was found to be a function of time and fluence, and showed a characteristic sigmoidal pattern. The 16O ions were more effective in the lower fluence range than 7Li ions. These results were compared with lipid peroxidation and hemolysis induced by gamma-radiation.
