AIMS: The aims of this study were to determine the frequency of microalbuminuria (MA) among pediatric patients with SCD and to determine risk factors for MA among those patients. SUBJECTS AND METHODS: A case–control study was carried out on 120 patients with SCD, 2–18 years old, registered at Basrah Center for Hereditary Blood Diseases, and 132 age- and sex-matched healthy children were included as a control group. Investigations included complete blood panel, blood urea, serum creatinine (Cr), urinalysis, and urinary albumin-to-Cr ratio (ACR). Logistic regression analysis was used to assess the predictors of MA. RESULTS: Among SCD patients, 39 (32.5%) had MA compared to 6 (4.5%) in the control group. The mean levels of blood urea, serum Cr, and ACR were significantly higher, and the urine-specific gravity was significantly lower in SCD patients than in the control group (P < 0.05). Logistic regression analysis revealed that frequent painful crisis (odds ratio [OR]: 12.146, confidence interval [CI]: 3.439–42.952), high serum ferritin (OR: 8.146, CI: 1.802–36.827), deferoxamine therapy (OR: 23.423, CI: 3.961–60.509), and female sex (OR: 4.590, CI: 1.225–17.202) are independent risk factors for MA (P < 0.05). CONCLUSION: The frequency of MA was high among our pediatric SCD patients. Risk factors for MA include female sex, nutritional factors, painful episodes, and iron overload. This is important for planning for future follow-up and management of this common disease in our locality.","PeriodicalId":53847,"journal":{"name":"Iraqi Journal of Hematology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47996822","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}

HLA tissue compatibility percentage is the most important parameter that increases the success of transplantation in donor selection. Pretransplant HLA tissue typing can be looked at in low and high resolution according to the facilities of the center and the urgency of transplantation. Many centers evaluate HLA HLA-A, B, C, DP, DQ, DR tissue types before allogeneic bone marrow transplantation. HLA tissue types differ in many races and even between unrelated individuals of the same race. AIMS: This study aimed to show the common human leukocyte antigen (HLA) rates and differences in Syrian and Turkish ethnicity patients who underwent allogeneic stem cell transplantation in our center. MATERIALS AND METHODS: HLA tissue similarities between Turkish and Syrian patients were revealed by examining the HLA tissue records of Turkish and Syrian patients who applied to the bone marrow transplant unit of Inonu University Turgut Ozal Medical Center between December 2009 and November 2021 for allogeneic stem cell transplantation. RESULTS: As a result of our study, it has been observed that there are similarities in terms of HLA A*02, HLA B*35, HLA C 04,07,12, HLA DP*02,04,11 HLA DQ*02,03,05,06, HLA DR*01,03,11,13 in Turkish and Syrian patients.

FMS-like tyrosine kinase 3 (FLT3) is a cellular receptor belongs to the Class III receptor tyrosine kinase family. The main expression of FLT3 on bone marrow (BM) cells especially CD34+ hematopoietic stem cells, early progenitor cells, dendritic progenitor cells, and other cells of organs (brain, placenta, and testis). Activation of FLT3 results in increased cell proliferation, decreased cell apoptosis, and inhibition of differentiation of cells. This study aims to detect the expression of the FLT3 cluster of differentiation antigen 135 (CD135) in childhood B-ALL patients. Moreover, to correlate this expression with hematological parameters include a complete blood count and BM examination findings and clinical parameters. PATIENTS, MATERIALS AND METHODS: This study was conducted on 30 newly diagnosed pediatric ALL patients. Diagnosis of the disease was based on the blood film, BM examination findings, cytochemistry, and flowcytometry of peripheral blood (PB) and/or BM sample, 1 ml of PB and/or BM sample was collected in EDTA tubes for flowcytometry for detection of CD135. RESULTS: This study found that male patients were more than females with a male-to-female ratio (1.14:1) and a median age of 5 years. Most of the patients had a positive expression of the FLT3 receptor and according to NCI risk groups, 60% of patients fall in the standard risk and 40% in the high-risk group. There was a significant correlation between the level of FLT3 (CD135) and age but no significant correlation with hemoglobin, white blood count, platelets, and peripheral or BM blast percentage. CONCLUSION: In this study, the patients with positive FLT3 blast cells (which is a bad prognostic factor) were associated with good prognostic factors. This proves that FLT3 is an independent prognostic factor.","PeriodicalId":53847,"journal":{"name":"Iraqi Journal of Hematology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45943715","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}

AIM: The aim was to evaluate the safety and efficacy of the coagulation factor VIIa, recombinant (AryoSeven RT) among congenital FVII deficiency patients at different centers in Iraq. METHODOLOGY: This is a prospective, observational, noninterventional study done at 5 medical centers in Iraq and it included 22 patients with FVII deficiency (congenital form) older than 14 years of age. Patients are recorded and followed for 6 months and they are subjected to AryoSeven RT depending on each patient individually. There were 3 main visits and 3 unscheduled visits for each patient during the study. Effectiveness evaluation was performed 6 h after each intervention. Adverse drug reactions related to the administration of AryoSeven RT were reported for each patient during each visit. RESULTS: A total of 22 participants were enrolled, classified into 18 (82%) were female and 4 (18%) were male. The mean age was 27.5 ± 14.0 years. Among 91 bleeding events, AryoSeven RT efficacy was effective in 89 events, excellent in 1 event, and partially effective in also 1 event. There was a reduction of PT from baseline (57.3 ± 15.2 s) to (13.9 ± 6.2 s) after 1st dose of AryoSeven RT and more reduction after 2nd dose of therapy (13.4 ± 4.4 s) and these were statistically significant (P = 0.001). Regarding FVII activity, there was a significant increase from baseline (8.4% ± 8.0%) to (95.8% ± 46.6%) after 1st dose and (131.8% ± 40.1%) after 2nd dose of AryoSeven RT with P = 0.001 for both. No major adverse events were reported except for headache in one participant (4.5%), and injection site reactions in three participants (13.6%).)

Ameen, Haithem A Al-Rubaie","doi":"10.4103/ijh.ijh_31_22","DOIUrl":"https://doi.org/10.4103/ijh.ijh_31_22","url":null,"abstract":"BACKGROUND: Chronic lymphocytic leukemia (CLL) is a malignancy of mature appearing clonal B lymphocytes where there is a progressive accumulation of leukemic cells in peripheral blood, bone marrow, and secondary lymphoid tissues as a consequence of defective apoptosis and survival signals derived from the microenvironment. The soluble CD23 (sCD23) is a 25 kDa fragment that can be found in serum, plasma, and urine in patients with CLL. It is a B-cell growth factor. B-cell maturation antigen (BCMA) is a member of the tumor necrosis factor superfamily, it enhances the survival and proliferation of mature B cells and plasma cells through signal transduction of the B-cell activating factor and a proliferation-inducing ligand. AIMS: The aims of this study were to assess the serum levels of sCD23 and BCMA in newly diagnosed CLL patients and to correlate them with clinical Binet staging and other hematological and clinical parameters. PATIENTS, MATERIALS AND METHODS: This study was conducted on 54 newly diagnosed CLL patients and 27 healthy controls. Diagnosis of CLL patients was based on lymphocyte count of >5 × 109/L and immunophenotyping. The serum levels of sCD23 and BCMA were measured in both groups using an enzyme-linked immunosorbent assay. RESULTS: Serum levels of sCD23 and BCMA were significantly higher in CLL patients in comparison with control group (P < 0.001 for both). There was a significant direct association between serum levels of sCD23 and BCMA with the clinical Binet stage of the disease (P < 0.001 for both). sCD23 showed significant correlation with hemoglobin (Hb) level (P < 0.001), total white blood cell (WBC) count (P = 0.001), lymphocyte count (P < 0.001), platelet count (P = 0.017), B-symptoms (P = 0.001), and splenomegaly (P = 0.019), whereas BCMA has significant correlations with Hb level, total WBC count, lymphocyte count (P < 0.001 for each one), B-symptoms (P < 0.001), lymphadenopathy (P = 0.001), splenomegaly (P = 0.024), and hepatomegaly (P = 0.04). CONCLUSIONS: The levels of serum sCD23 and serum BCMA increase with advancing Binet stages of the disease indicating their possible usefulness as good and reliable parameters for prognostic evaluation in CLL patients. The significant correlation of serum sCD23 and serum BCMA with hematological parameters and clinical features render them as reliable tumor burden markers in CLL patients.","PeriodicalId":53847,"journal":{"name":"Iraqi Journal of Hematology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43638463","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}
