Patients with leukemia might be at a higher risk of developing COVID-19 because of associated myelosuppression in the case of AML. The authors present the management of a confirmed case of severe COVID-19 in a newly diagnosed patients with acute promyelocytic leukemia (APL) and review of the literature. Case A 33-year-old man got referred to the hematology outpatient clinic because of marked leukocytosis and moderate thrombocytopenia. He was diagnosed as having COVID-19 pneumonia and high-risk APL at the same time. AIDA protocol and COVID-19 pneumonia treatments had to be given at the same time. At the end of this successful treatment process, the patient was discharged with complete remission. Discussion APL is a distinct and rare type of AML. Coagulopathy is the most important cause of early death owing to APL. Although there is no consensus regarding the treatment approach to be applied in the co-existence of AML and COVID-19 infection, there are various recommendations. Conclusion The simultaneous diagnosis of high-risk APL and covid-19 is a challenging process for both patients and clinicians.","PeriodicalId":42139,"journal":{"name":"Egyptian Journal of Haematology","volume":"47 1","pages":"74 - 79"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49010831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common type is latent tuberculosis infection (LTBI); however, patients can develop active TB disease and become infectious. Managing LTBI properly can prevent active disease evolution, and exclusion of active TB is the main primary question in LTBI management. Protein C (PC) and antithrombin (AT) are natural anticoagulants with anti-inflammatory properties, so they are suggested to have a role in hypercoagulability due to inflammatory processes. Aim To correlate PC and AT levels in TB patients with patients’ coagulable and clinical state. Patients and methods Sixty patients (20 pretreatment, 20 posttreatment active TB, and 20 LTBI) and 20 normal-controls were included. Activity levels of PC and AT were measured and correlated to patients’ coagulable and clinical states, and routine laboratory results. Results Activity levels of PC and AT are significantly low in active TB, increasing with treatment, and normal in LTBI. No thromboembolic events were detected in all patients included, so correlation with PC and AT could not be verified. Conclusion Active TB is associated with hypercoagulable state, with low activity levels of PC and AT. Both proteins are suggested to be used as adjuvant markers of activation of LTBI and during their pretreatment assessment, together with monitoring therapeutic response in patients with active TB.","PeriodicalId":42139,"journal":{"name":"Egyptian Journal of Haematology","volume":"46 1","pages":"201 - 207"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48636063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to analyze leukocyte β-glucocerebrosidase (β-GBA) levels and plasma chitotriosidase (PCT) activity in patients with β-TM and to determine the significance of these two enzymes in this disease. Patients and methods This study included 40 patients, 18–55 years of age, who were under follow-up for β-TM in our clinic. Physical examination, ECG, echocardiography, laboratory findings, and the results of imaging tests obtained during routine control visits were recorded. Leukocyte β-GBA and PCT activity levels were analyzed in the blood using fluorometric methods. Results The average age of the 40 patients, which included 24 (60%) women and 16 (40%) men, was 28.5±7.8 years. Leukocyte β-GBA levels were below 2.5 nmol/mg/h in 15 patients, and PCT activity was above 200 μmol/l/h in 10 patients. A positive correlation was detected for leukocyte β-GBA enzyme levels with cardiac T2FNx01 (P=0.024); however, a negative correlation was detected with intraventricular septum thickness (P=0.029) and left heart posterior wall thickness (P=0.030). Conclusion Lower leukocyte β-GBA levels and higher PCT activity may be present in patients with β-TM. There may be an increase in cardiac iron load, intraventricular septum thickness, and left ventricle posterior wall thickness, especially in patients with lower leukocyte β-GBA levels and higher PCT activity. Therefore, leukocyte β-GBA levels and PCT activity may be associated with cardiac complications in patients with β-TM.","PeriodicalId":42139,"journal":{"name":"Egyptian Journal of Haematology","volume":"46 1","pages":"234 - 242"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43984646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the definition of CD34+ different subsets has gained importance concerning the engraftment kinetics and immune reconstitution, after hematopoietic stem-cell transplantation. Objectives This study aimed to describe and enumerate CD34 subpopulations, using a multicolor flow-cytometric protocol, based on the expression of CD133, SSEA-4, CD38, and CD10, in an attempt to explore the impact of the different CD34 subsets on engraftment kinetics, patient, and graft outcomes. Methods A total of 33 bone marrow transplant (25 autologous and 8 allogenic) Egyptian patients were included. Detailed demographic, clinical, and laboratory data, as well as echocardiography and pulmonary-function tests, were collected from all participants enrolled in the study, before transplantation. All patients were monitored up to 1 year post transplantation, for the development of complications. Discrimination of the distinct stem-cell subsets in the harvest was performed on NAVIOS flow cytometer, using multicolor FCM phenotyping. Results Seven CD34+ hematopoietic stem cell subpopulations were identified in the harvest blood by flow cytometry: the multipotent progenitor (MPP), erythromyeloid progenitor, B-lymphoid progenitor (BLP), multilymphoid progenitor (MLP), lymphomyeloid progenitor (LMPP), granulocyte and macrophage progenitor (GMP), and the late GMP. The MPP was the most frequently encountered subpopulation, whereas the BLP was the least-encountered one. In addition, the % population and absolute count of the late GMP were significantly higher after autologous transplantation (P=0.049 and 0.048, respectively). The absolute count of the MLP was significantly higher after G-CSG + chemotherapy-mobilization technique (P=0.039). Higher absolute count of the MLP in the harvest was associated with longer post-transplant 1-year survival of patients (P=0.025). The % population of the GMP in the harvest was significantly correlated with faster engraftment (P=0.039). However, a higher proportion of the late GMP (P=0.041and 0.028, respectively), along with higher absolute count of the LMPP, has been significantly encountered in patients who developed post-transplant disease relapse (P=0.050). By drawing a receiver-operating characteristic curve, only the size of the MPP population at cutoffs of ≤18.85% and ≤165312, respectively, could be significantly used to predict the persistence of cytopenia at 3 months after transplantation. Conclusion This study found that discrimination and quantification of the different CD34 stem-cell subsets might play a pivotal role for better understanding of engraftment kinetics and prediction of post-transplant graft and patient outcomes.","PeriodicalId":42139,"journal":{"name":"Egyptian Journal of Haematology","volume":"46 1","pages":"214 - 226"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44279481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective The experience with patients with CML regarding clinical features, as well as efficacy and safety of tyrosine kinase inhibitors (TKIs) as a treatment for CML was analyzed in this study. Materials and methods A retrospective study was conducted in patients diagnosed with CML regarding clinicomorphological features and treatment outcome in a tertiary hospital located in southwest Saudi Arabia from July 2004 to June 2020. The study population included patients diagnosed with CML who were older than 12 years. Patients younger than 12 years, BCR-ABL-negative CML, and other myeloproliferative neoplasm were not included in the study. Medical records of patients were reviewed, and data were collected. Results During this period, 80 patients with CML were treated. The mean age was 41.6 years, with a slight male predominance. Overall, 90% of patients presented with abdominal discomfort and fatigue. Chronic phase represented 90% of all cases, with 55.5% showing intermediate-risk category of the Sokal score. Patients receiving a first-line treatment with first-generation TKI represented 42.5% and second-generation TKIs represented 52.5%. Complete hematological response was noted in 96.2% of patients after 3 months of treatment, and a major molecular response was seen in 77.2% of patients after 12 months of treatment. Adverse events (AEs) of TKI noted were 16 (20%), of which 81.2% were grade 1. They were as follows: pleural effusion in four (5%), neutropenia in two (2.5%), bone marrow suppression in four (5%), and skin itching in six (7.5%) in patients with dasatinib, contributing to 56.2% of all AEs. Overall, four (5%) patients were in treatment-free remission. Mean survival period in chronic phase CML was found to be 15.4 years, whereas in advanced phase CML was 4.7 years. Conclusion Our study revealed that patients with CML were predominantly middle aged with a slight male preponderance. Most patients presented in the chronic phase, with the Sokal score in the intermediate-risk category. Patients were treated upfront with TKIs with a significant number receiving second-generation TKIs. First-generation TKIs had lesser AEs as compared with second-generation TKIs, but these toxicities were mild.","PeriodicalId":42139,"journal":{"name":"Egyptian Journal of Haematology","volume":"46 1","pages":"208 - 213"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49083960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of these is the significant presence of neonatal thrombocytopenia and the need for lots of platelet transfusions per an infant. Many neonatal factors can cause thrombocytopenia, but we observed severe, prolonged thrombocytopenia in infants who received specifically vancomycin for sepsis or other medical/surgical conditions. Literature search revealed that vancomycin can cause immune thrombocytopenia by inducing platelet antibodies, though this is scarcely described in neonates. Participants and methods This is a hospital-based longitudinal study held in NICU during February 2017 to February 2019. All admitted neonates (term and preterm) who received vancomycin were involved, but those with maternal thrombocytopenia, systemic lupus erythematosus (SLE), maternal eclampsia/HELLP (Haemolysis, Elevated Liver enzymes, Low Platelets) syndrome, and Intr Uterine Growth Rrestriction (IUGR) were excluded. Results Of 117 infants admitted in this period, 68 infants fulfilled the inclusion criteria. The severe decline in platelet count observed on the second to third day of vancomycin treatment continued throughout the treatment and started to rise 2–3 days after discontinuation. During treatment with vancomycin, platelet transfusion 2–3 times a day was observed not to raise platelet level significantly, but it prevented serious bleeding. Conclusion Vancomycin-induced thrombocytopenia in neonate is a rising new problem in NICUs. The authors may need to add adjunctive intravenous immunoglobulins or methylprednisolone or change the dosing system to smaller frequent doses, given over longer time, to overcome this serious problem.","PeriodicalId":42139,"journal":{"name":"Egyptian Journal of Haematology","volume":"46 1","pages":"255 - 257"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47172461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods Twenty-nine survivors of childhood ALL and 35 age- and sex-matched healthy controls were evaluated for anthropometric measurements, including weight, height, body mass index (BMI), and waist-to-hip ratio. Body composition was analyzed using Tanita SC-330P scale. Measurement of fasting insulin, glucose, lipids, and serum leptin was done for all participants. Results BMI-standard deviation score (SDS) was significantly higher among the survivor group (mean±SD 0.79±1.2) versus controls (0.25±0.85, P=0.041). Obesity/overweightness were more prevalent among survivors than the control group (34.5% and 17.6%, respectively); however, the difference did not reach statistical significance (P=0.215). There was no difference between both the groups when comparing waist-to-hip ratio, body fat %, fat-free mass %, muscle mass %, and total body water % as well as serum leptin and lipid profile.

Hemostatic abnormalities are common in inflammatory bowel disease (IBD) with higher risk for a hypercoagulable state and prothrombotic conditions. In addition, a few cases of acquired coagulopathy with higher risk of bleeding have been reported. The involved pathophysiologic mechanisms are complex and incompletely understood. Objective This is a case–control study that aimed to assess the levels of Von Willebrand factor (VWF) in IBD as a marker of disease activity and its relation to higher risk of bleeding or thrombotic events. Patients and methods A total of 46 patients with IBD aged 18 years or older were enrolled in the study. After consenting, patients were divided into two groups: one group included 23 patients with active IBD and the other group included 23 patients with inactive IBD. Activity of Crohn’s disease was assessed through the Harvey-Bradshaw index and activity in patients with ulcerative colitis was evaluated with the simple clinical colitis activity index. The white blood cell count, hemoglobin level, platelet count, activated partial thromboplastin time, C-reactive protein, erythrocyte sedimentation rate, albumin, fecal calprotectin, VWF antigen level (VWF:Ag), and VWF ristocetin cofactor activity (VWF:RCo) were measured. The VWF:RCo/VWF:Ag ratio was calculated. Results There were significant differences in the mean±SD of vWF antigen and vWF:RCo levels between active IBD group (189.30±62.83 and 101.73±23.42, respectively, P=0.001) and inactive IBD group 177.30±64.90 and 97.08±24.21, respectively, P=0.001). The IBD activity index was correlated with VWF antigen (r=0.78 P=0.001) and VWF:RCo levels (r=0.74 P=0.001). VWF antigen and VWF:RCo were correlated with fecal calprotectin (r=0.65, P=0.001, and r=0.67, P=0.001, respectively). The odds ratio of an elevated vWF antigen greater than 150% was 24 (95% confidence interval: 4.38–131.47) in the group with active IBD compared with the inactive IBD group. The VWF:RCo/VWF:Ag ratio of less than 0.7 which reflects the possibility of acquired Von Willebrand syndrome was detected in five patients (21.7%) with active IBD in comparison with only one patient (4.3%) in the inactive IBD group, with odds ratio of 6.1 (95% confidence interval: 0.65–57.1). Conclusion VWF antigen and activity levels can be used as markers for evaluation of IBD activity. Assessment of VWF in IBD could be significant for better hemostatic control of such patients. Activated coagulation system in IBD is well known; however, precautions for coexisting acquired functional coagulopathy should be considered.","PeriodicalId":42139,"journal":{"name":"Egyptian Journal of Haematology","volume":"46 1","pages":"227 - 233"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45101841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
