This study aims to identify two subsets of NK, cytotoxic (cluster of differentiation [CD] 16+bright) and cytokine-producing NK (CD56+bright) in newly diagnosed CML patients. This study is conducted on 20 newly diagnosed Iraqi patients (12 males and 8 females) with CML, in chronic phase, at the age range of 17–55 years. Along with patients, 20 healthy subjects (with matched age and gender) were enrolled to act as a control group. To identify NK cells and their subsets in peripheral blood samples, the expression of CD45, CD3, CD56, and CD16 markers was evaluated by flow cytometry technique. Furthermore, the serum level of interferon gamma (IFN-γ) and interleukin (IL)-18 was determined by the enzyme-linked immunosorbent assay technique. The age of patients at the diagnosis of disease is (35.6 ± 12.2 years) and the male: female ratio was 1.5:1. The serum level of IL-18 in newly diagnosed CML patients (30.3 ± 6.5 pg/mL) was significantly (P < 0.0001) higher than those in control group (18.3 ± 7.8 pg/mL), while the serum levels of IFN-γ in newly diagnosed patients are significantly (P = 0.006) dropped down to (89.1 ± 7.2 pg/mL from that in control group (109.4 ± 30.3 pg/mL). The percentage of NK cells in newly diagnosed CML patients is significantly lower than in control group. There is a significant elevation in the cytotoxic NK cells (CD16+bright) subset, and a significant decrease in the cytokine-producing NK subset (CD56+bright) in newly diagnosed patients when compared to those in control group. Although there is an elevation in the percentage of cytotoxic NK cells (CD16+bright) subset of CML patients at the first diagnosis, these cells are not able to recognize and attack malignant cells, which may be due to low expression of their activating receptors and needs more investigation. Furthermore, present results found a low percentage of cytokine-producing NK cells (CD56+bright) and a low level of IFN-γ in CML patients, although there is an elevation in IL-18, which indicates that IL-18 may be not the main stimulator to these cells, so activation pathway of this subset of NK cells needs further investigation.","PeriodicalId":53847,"journal":{"name":"Iraqi Journal of Hematology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139198023","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 study aimed to look into different expression patterns, prognostic value, and clinical importance of lncRNA small nucleolar RNA host gene 5 ( SNHG5) and promoter of cyclin-dependent kinase inhibitor 1A antisense DNA damage-activated RNA ( PANDAR ) genes in Egyptian adult patients with AML. SUBJECTS AND METHODS: The case–control study was conducted between 2019 and 2022 at the Clinical Pathology Department at the National Cancer Institute, Cairo University, Egypt. The study involved 80 recently diagnosed patients with AML and 20 healthy controls. Real-time quantitative reverse transcription polymerase chain reaction was used to assess the levels of expression of SNHG5 and PANDAR genes. RESULTS: In comparison to healthy controls, there was a significantly higher SNHG5 gene expression ( P = 0.026) and PANDAR expression ( P < 0.001) in patients’ bone marrow samples. The study of the correlations revealed a significant positive association between SNHG5 and PANDAR genes in AML patients. The overall survival (OS) was significantly better in the low SNHG5 gene expression group than in the high SNHG5 gene expression group. No significant difference was detected regarding the disease-free survival (DFS) between patients with low expression and high expression of the SNHG5 gene . No significant variation between high PANDAR gene and low PANDAR gene expression regarding OS and DFS. CONCLUSION: SNHG5 and PANDAR may have a pathogenic role in AML, and their overexpression might be considered a marker for diagnosis in AML patients in Egypt. SNHG5 expression can be used as a predictor for OS, while PANDAR expression cannot be used as a predictor for OS or DFS in patients.","PeriodicalId":53847,"journal":{"name":"Iraqi Journal of Hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135429943","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}

AIMS OF STUDY: The aims of this study were to evaluate the clinical presentation and severity of COVID-19 among pediatric patients with hemoglobinopathies, assess risk factors, and outcome among studied patients. PATIENTS AND METHODS: An analytical, cross-sectional study has been carried out on children and adolescents with hemoglobinopathies, for the period from the first of May 2021 to September 2022. In addition to patient’s data and thorough physical examination, patients were followed concerning the course, complications, and disease outcome. Investigations included complete blood count, inflammatory markers, liver, and renal function tests. RESULTS: Out of 42 patients with hemoglobinopathies and COVID-19, the majority of patients 35 (83.3%) gave a history of COVID-19 exposure, with a median of 5 days for the presentation since exposure and 23 (54.8%) needed hospitalization. All studied patients had fever, followed by cough in 36 (85.7%) and shortness of breath (42.9%). No death was reported in studied patients. The lymphocyte count was significantly lower and C-reactive protein and D-dimer levels were significantly higher in sickle cell disease (SCD) patients with COVID-19 as compared to thalassemia patients, P < 0.05. Twenty-two patients (52.4%) had mild COVID-19 disease, 12 (28.6%) moderate, and 8 (19%) with severe disease. Regression analysis revealed that acute chest syndrome (ACS) as COVID-19 infection presentation, high white blood cells count, and elevated total serum bilirubin were significant variables associated with severe COVID-19 infection, P < 0.05. CONCLUSION: The clinical course of hemoglobinopathy patients with COVID-19 infection is similar to that in the general population and no death was reported among studied patients. However, clinicians treating patients with SCD need to be aware of COVID-19 infection when diagnosing ACS.","PeriodicalId":53847,"journal":{"name":"Iraqi Journal of Hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135975614","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}

Neutrophils are the predominant immune cells that infiltrate joints after hemorrhage. Tissue injury is often accompanied by the production of neutrophil extracellular traps (NETs), which are DNA constructs containing attached granular enzymes. AIMS OF STUDY: The aim of this study was to identify the presence of neutrophil extracellular traps including the neutrophil elastase (NE) and myeloperoxidase (MPO), in patients with hemophilia A presented with hemarthrosis. SUBJECTS AND METHODS: During a period of 8 months from November 2022 to June 2023, 50 persons were recruited cross-sectional study was conducted. In the current study, a sample of 25 individuals with hemophilia A presenting with hemarthrosis were included. Additionally, a control group of 25 unrelated, almost healthy persons,matched in terms of age and sex were also included. NE and MPO levels in blood were measured by flow cytometry technique. RESULTS: The level of MPO and NE in the blood was significantly higher in hemophilia A patients than controls. In the results of hemophilia A patients, the mean and standard deviation of MPO were 3253.36 +_1865.48, while for NE it was 5229.08+_2667.43. These values were found to be statistically significant P <0.05 when compared to the control group.

The effectiveness of preserved blood cells following transfusion is affected by a variety of factors, like changes in miRNA levels. One day, these small RNAs might help determine the efficacy and safety of blood products. AIMS: This study sought to identify the miRNA present in both fresh blood and stored blood because there is growing evidence that these cells are enriched with miRNAs. MATERIALS AND METHODS: Blood samples were taken from three healthy donors to detect the expression of miRNAs using illumina platform for RNA sequencing. Total RNA was isolated from stored units at 0, 14, 21, and 28 days, respectively. Bioinformatics analysis has been carried out to analyze the miRNAs. RESULTS: The majority of miRNA expression was decreased in time-dependent manner, particularly after day 14 of packed blood cells (PBCs) storage such as hsa-miR-20a-5p, hsa-miR-17-5p, and hsa-miR-423-3p. While other miRNAs such as hsa-miR-320a-3p, hsa-miR-186-5p, and hsa-miR-486-5p, showed a significant re-upregulated after day 21. CONCLUSION: In summary, the PBCs at days 14 and 21 had the lowest levels of miRNAs, which may indicate less of a relationship with storage lesions. However, older PBCs displayed significant levels of miRNAs, which could indicate storage lesions or cause a number of clinical issues for the recipients.","PeriodicalId":53847,"journal":{"name":"Iraqi Journal of Hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136068221","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}

Typhidot IgM test is reported in a few studies to give false-positive results in various viral illnesses in the past. The aim of this study was to estimate the typhidot IgM positivity rate in reverse transcription-polymerase chain reaction (RT-PCR)-confirmed COVID-19 patients. MATERIALS AND METHODS: The present study was a cross-sectional study conducted at a tertiary care hospital. All symptomatic patients having fever that were admitted between April 1, 2021, and July 15, 2021, with a confirmed RT-PCR-positive result for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) were included in the study. Serological testing was done by typhoid IgM/IgG rapid diagnostic test for all SARS-CoV-2 RT-PCR-positive patients. The primary outcome studied was to estimate the typhidot IgM positivity rate among RT-PCR-confirmed COVID-19 patients. The secondary outcome studied was to determine the correlation between SARS-CoV-2 RT PCR cycle threshold (CT) value and typhidot-positive result. RESULTS: Three hundred and five (17.99%) out of 1695 samples of confirmed COVID-19 patients were positive for typhoid serology by typhidot IgM test. However, upon performing Point-Biserial correlation analysis ( P = 0.832, r = 0.021), no correlation was seen between RT-PCR CT value and typhidot result. CONCLUSIONS: Typhidot test is a nonspecific diagnostic test for typhoid fever which can be false positive in COVID-19 patients. Hence, physicians should take this into consideration to avoid misdiagnosis and delay in accurate treatment of acute febrile illness cases, especially in the present scenario of COVID-19 endemicity.","PeriodicalId":53847,"journal":{"name":"Iraqi Journal of Hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136103204","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}
