In the past few decades, several studies have found that iron deficiency markedly affects the immune system. However, data on the effect of iron deficiency on immune function are still confusing and contradictory. Aim To assess the effect of iron-deficiency anemia on cell-mediated immunity. Patients and methods The percentage and count of T-lymphocytes (CD3+) and their CD4+ and CD8+ subsets and CD4+/CD8+ ratio were evaluated in 25 iron-deficient and 15 healthy adult women. The effect of iron therapy on the same parameters was also assessed in patients after correction of anemia. Results In our study, there was no statistically significant difference between patient and control groups regarding CD3+, CD4+, and CD8+ cell counts and percentages and CD4+/CD8+ ratio, with no statistically significant difference after iron therapy. However, it was found that serum ferritin level was significantly positively correlated with CD4+/CD8+ ratio and CD4+ cell percentage and absolute count and significantly negatively correlated with CD8+ cell percentage.

The studies on TTP are scarce; most of them have small numbers of patients. Since not enough data on Egyptian patients with TTP can be found in the literature, we carried out this retrospective study to define the therapeutic modalities and outcome of these patients. Patients and methods We studied the records of patients clinically diagnosed with TTP from 2006 to 2020. Twenty-nine patients were diagnosed with TTP. However, full records were available only for 22 patients. The primary outcome of the study was the 1-year survival. Other outcomes were the factors on which the survival seemed to depend on such as age, platelet count, lactate dehydrogenase (LDH), serum creatinine, hemoglobin, reticulocytic %, plasma volume exchange (PVE), days to start of treatment, and indirect bilirubin. Results Platelet count change was negatively correlated with both the number of plasma exchange sessions and the days to start of treatment, but it was positively correlated with the volume of plasma exchange. Univariate analysis identified factors associated with better survival of the patients: LDH, reticulocytic percent, days to start of treatment, serum creatinine, PVE, and hemoglobin level. The multivariate analysis revealed that the independent factors affecting the survival were LDH, reticulocytic percent, hemoglobin level, and age.

Patients and methods Cases were adults with SCA with PHT. Controls were patients with SCA without PHT. All patients were recruited in a steady state. Echocardiography was done according to the recommendation of the American Society for Echocardiography. Measures of RV function used were RV fractional area change, peak tricuspid annular systolic velocity (S′), and tricuspid annular plane systolic excursion. PHT was estimated from tricuspid regurgitation jet velocities. Mean pulmonary arterial pressures more than 20 mmHg were said to have PHT. Results Of 86 patients, 14 had PHT. The mean values of RV systolic function (RV fractional area change, S′, and tricuspid annular plane systolic excursion) were not significantly different between cases and controls. Transtricuspid A was faster, with the E deceleration time shorter in those with PHT. Loud P2, PR interval, and waist–hip ratio (especially in women) correlate directly with PHT, whereas systolic blood pressure, early E deceleration time, and a history of hemolytic crisis correlated inversely with PHT. Systolic blood pressure and loud P2 are independent predictors of PHT in this study. Conclusion PHT had a prevalence of 16.3% in patients with SCA in this study.

In this review, 20 articles published between December 2019 and January 2021 were included, which reported cases of patients with SCD diagnosed with COVID-19. Patients and methods A total of 343 patients with SCD worldwide were included (mean age is 25 years). Overall, 56% of the study population was female. A total of 322 patients had symptoms; 193 patients presented with vaso-occlusive crises and COVID-19 symptoms. Moreover, 15% reported only vaso-occlusive crises symptoms without COVID-19 symptoms. Typical acute chest syndrome symptoms were reported in 27 patients. Results Overall, 79% of the population was admitted to hospitals. Blood transfusion was received by 51%, and 23% needed oxygen.

Objectives The present study aims to evaluate the laboratory and transfusion statuses of adult patients admitted to our hospital and receiving outpatient/inpatient treatment and diagnosed with thrombocytopenia (<100 × 109/l). Design Single-center, retrospective, laboratory-based study. Patients and methods In the study, after obtaining permission of the hospital’s Non-Invasive Clinical Research Ethics Committee, the information of patients diagnosed with thrombocytopenia (platelet count <100 × 109/l) and who were examined and treated in the outpatient/inpatient settings between 2008 and 2010 were retrospectively analyzed using patient files and the hospital electronic database. Sample size A total of 1020 patients diagnosed with thrombocytopenia. Results The patients were divided into groups according to the most common diagnoses for diseases associated with thrombocytopenia (hematological malignancy, disseminated intravascular coagulation (DIC)-sepsis, immune thrombocytopenia (ITP), infection, and chronic liver disease (n=708). Chemotherapy-induced, drug-induced, nutritional (B12, folate deficiency, etc.), OKIT, pregnancy-induced thrombocytopenias and other less common causes of thrombocytopenia were evaluated in a separate group (n=312). It was found that female patients were more frequently diagnosed with ITP (71.7 vs. 28.3%). Sex distributions were similar in other groups. The highest mean age (71 years: 50/80) was observed in patients with DIC-sepsis, whereas the lowest mean age was found in patients with ITP (40 years: 30/57) (P<0.001). It was found that the most frequent need for transfusion developed in patients diagnosed with acute myeloid leukemia, acute lymphoblastic leukemia, and aplastic anemia. Conclusion In this study, it was determined that the prevalence of thrombocytopenia was highest in patients diagnosed with hematological malignancy, ITP, and DIC-sepsis, respectively. In cases of hematological malignancy, the need for replacement of blood products is considered to be inevitable during the treatment process of the underlying disease compared with other clinical conditions.","PeriodicalId":42139,"journal":{"name":"Egyptian Journal of Haematology","volume":"47 1","pages":"35 - 43"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46815379","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}

Although these disorders are classified to be rare, their exact prevalence is still unknown; however, they are more frequent in communities where consanguineous marriages are common. Aim To study platelet surface glycoproteins expression using flow cytometry and to examine their correlation with bleeding severity using International Society of Thrombosis and Hemostasis–Bleeding Assessment Tools (ISTH-BAT) as bleeding score of choice. Patients and methods This case–control study included 51 patients with bleeding disorders recruited from the Department of Pediatric Hematology, Assiut University Hospital, in addition to 36 apparently healthy age- and sex-matched controls. All patients were tested for complete blood count (CBC), prothrombin time, partial thromboplastin time, platelet aggregation, and platelets surface glycoprotein analysis by flow cytometry. ISTH-BAT was used to register bleeding data for patients. Results GT and BSS had some similarities regarding the presentation and bleeding severity, but when CBC, platelet aggregation studies, and flow cytometric analysis were done, differentiation became much easier. GT patients showed a decrease in the expression of CD41 and CD61. Type I GT patients had more bleeding severity than type II and type III. BSS patients showed a decrease in expression of CD42b. There are correlations between the bleeding severity and CD41 in GT, and between the severity and CD42b in BSS.
