Objective: In Japan, red blood cell (RBC) solution is usually transported by car from a medical institution to the patient’s house for home transfusion. However, there are no regulations for transporting blood by car in the medical setting. Therefore, we assessed and compared the methods (containers) used for transporting the RBC solution by car. Materials and Methods: Irradiated RBC solution samples (280 mL) supplied by the Japan Red Cross Society were each divided into two bags. The quality of blood transported by car (1 - 2 hours) in an active transport refrigerator (ATR) (control group) was compared with that transported in a cooler, or styrofoam box (study group). We tested the hemolytic effects of transportation by car, storage, and filtration through a transfusion set on the lactate dehydrogenase (LD) levels in the RBC solutions. Results: Post-filtered LD levels were significantly higher in the RBC solutions transported in a cooler-box with inadequate temperature control when compared to those transported in an ATR with optimal temperature control. However, under conditions of optimal temperature control, the post-filtered LD levels were comparable in the control and study (both cooler and styrofoam boxes) group RBC solutions. Conclusion: Temperature management is critical for the maintenance of the quality of the RBC solution transported by car.

In the Democratic Republic of the Congo, the sickle cell trait carriage is estimated at 25%. Routine neonatal screening is not a common practice, leading to a very late diagnosis. In this study, the screening of pregnant women was assessed as well as their attitudes. This is an analytical cross-sectional study conducted in 245 pregnant women, sampled by convenience in four hospitals in Kisangani city (Democratic Republic of Congo) and screened using the sickle SCAN® test, from February 1 to July 31, 2019. The sensitivity and specificity of the latter were determined using liquid chromatography coupled with mass spectrometry as the gold standard. The attitudes of 240 pregnant women without previous screening history were assessed upon the announcement of the results. The sensitivity of screening for hemoglobin (Hb) AA and Hb AS was 96.69% and 98.39%, respectively; while the specificities were 99.43% and 96.32%, respectively. The Kappa coefficient (κ) was excellent. Concerning attitudes, Hb SS pregnant women and 55.17% of AS pregnant women worried when the results relating to their hemoglobin status were announced. The sickle SCAN® test was found reliable for sickle cell disease screening in Kisangani. The announcement of the results, mainly positive, raises worry among pregnant woman. Therefore, we recommend the involvement of a clinician psychologist for pre-screening counselling and for results announcement, as well as early newborns and unmarried teenage girls screening.

Multicolor flow cytometry (MFC) is essential to the diagnosis of non-Hodgkin lymphoma (NHL). In our institution, MFC specimens are submitted by pathologists or an ordering provider. As endoscopy has revolutionized the ability to biopsy the gastrointestinal (GI) tract, our lab increasingly receives provider-submitted, endoscopically-acquired GI biopsies (PEGIB) for MFC analysis. This study evaluates the clinical utility of MFC performed on PEGIB and proposes a new testing algorithm to enhance the pathology team’s role in MFC test utilization. Fifty-five archival PEGIB MFC cases were identified and histories were reviewed. MFC was non-contributory to the overall diagnosis in 85% of PEGIB. Retroactively implementing an algorithm that used PEGIB permanent section screening to triage the 55 archival cases resulted in the appropriate identification of 100% of specimens whose diagnosis would have benefitted from MFC analysis, and the optimization of test utilization by decreasing unnecessary MFC studies.

Hemophagocytic lymphohistiocytosis (HLH), which was first described in 1939 by paediatricians Scott and Robb-Smith, is a life-threatening disease. HLH is characterized as cytokine release syndrome which is caused by excessive but non-malignant activation of macrophages and/or histiocytes in bone marrow and other reticuloendothelial systems. EBV-HLH is the most common type of infection-associated HLH, has a high mortality rate without prompt and effective treatment. A previous study showed that the one-year mortality rate of EBV-HLH patients is 75%. Here we report a case of EBV-associated hemophagocytic syndrome in adult, and the lessons from the treatment process. Through this case, we think that for EBV-related HLH, EBV-DNA should also be monitored in addition to hemophagocytosis-related indicators during treatment. In addition, DEP regimen may not be suitable for patients who have received at least partial response, because impaired immunological functioning may lead to EBV and hemophagocytic re-activity.

Background: Toxoplasmosis is an extremely rare disease that occurs in the hosts contact with cat and dog frequently. Most human acute infections go unnoticed in immunocompetent individuals, and gradually transformed into chronic infection. However, while host immunity significantly waned, the risk of reactivation of chronic toxoplasma infection is greatly increased. Reactivation of latent toxoplasmic infection often presents with fever, leukopenia, thrombocytopenia, neurological signs and pneumonia. However, for the non-specific clinical and biological signs and its fetal outcome, toxoplasmosis is often misdiagnosed and only revealed at autopsy. Case Presenation: We report a case hospitalized for a week history of cough, anorexia and fatigue with nasal bleeding for a day. After hospitalization, broad-spectrum antibiotherapy was started without a clear diagnosis of infection. Then the patient did a lot of investigations to search the cause of infection, but there were no positive findings. However, an unexpected discovery was detected from peripheral blood smears, shows 1 - 3 μm in diameter, scattered, short and bow like microorganisms on Day 39 of hospitalization. Combined with the medical history and clinical manifestation, toxoplasmosis was diagnosed finally. Unfortunately, secondary hemophagocytic syndrome (HPS) was diagnosed only two days after targeted anti-infection therapy, and the patient died on Day 45 of hospitalization. Conclusions: Patient with unexplained long-term fever and neurological symptoms, interstitial pneumonitis or myocarditis, toxoplasmosis should be positively considered. Only early diagnosis and treatment can increase the possibility of a successful cure and avoid other secondary diseases.

Objective: Study the HBS1L-MYB (rs4895441 and rs9376090) genetic polymorphisms in Egyptian patients with β-thalassemia major and sickle cell disease and its relation to Hb F and severity of the disease. Background: Hb F is a predominant modulator for the severity of β-thalassemia major & sickle cell disease. Genetic polymorphism in the intergenic region (HBS1L-MYB) between GTP-binding elongation factor HBS1L and myeloblastosis oncogene MYB on chromosome 6q is associated with high fetal hemoglobin levels. Subjects and Methods: 150 subjects were included in this study. For all studied groups: Complete blood picture and serum ferritin were evaluated. For patients, hemoglobin variants were separated by High-performance liquid chromatography. Genotyping of HBS1L-MYB (rs4895441 & rs9376090) was evaluated by real-time polymerase chain reaction technique using TaqMan probe. Results: AG, CT genotypes, and G, C alleles of HBS1L-MYB (rs4895441 & rs9376090) were significantly high in sickle cell patients [OR (3.400); 95% C.I (1.482 - 7.799)], (p = 0.003) & [OR (4.522); 95% C.I (1.854 -11.029)], (p = 0.001) respectively. Also, a significant association was detected between polymorphisms and disease severity. However, in β-thalassemia major, no significant association was detected. Conclusion: In sickle cell disease patients, Genetic polymorphisms in HBS1L-MYB (rs9376090 & rs4895441) affect the level of Hb F which could improve the prognosis of these patients.

Background: Haematological abnormalities are strong independent predictors of morbidity and mortality in HIV infection. Objectives of the Study: This study was carried out to assess the pattern of the changes in the baseline peripheral blood cell counts among adult HIV positive patients. To also determine the CD4+ T cell levels and its correlation with the changes in the baseline cell counts of the patients using HIV negative blood donors as controls. Methods: This was a case controlled prospective study. The subjects were antiretroviral therapy naive adult HIV positive patients and HIV negative blood donor controls. Five milliliters (5 mls) of venous blood was collected from the cubitus of every consecutive consenting subject. Blood sample was analysed for baseline complete blood cell counts and the CD4+ T lymphocyte levels using Sysmex and Cyflow R Counter autoanalysers respectively. Obtained data was analysed with the statistical package for the social scientist (SPSS version 20.0). The Erythrocyte sedimentation rate of subjects was measured by the manual standard Westergreen method. Results: Of 300 subjects, there were 139 (46.3%) males and 161 (53.7%) females in the study. Anaemia was found in 72 (29.2%), leucopenia in 20 (8%) and thrombocytopenia in 6 (2.4%) of the patients. The mean erythrocyte sedimentation rates of the subjects were 81.88 mm/hr and 9.46 mm/hr (p = 0.000) for the patients and the controls respectively. The mean CD4+ T lymphocyte cell counts were 293 cells/μl and 750 cells/μl (p = 0.000) for the patients and controls respectively. Conclusion: Anaemia, leucopenia and thrombocytopenia were more prevalent among the studied HIV positive patients.

Hypertension (HTN) is a major health problem worldwide. It can lead to cardiovascular disease and functional disturbances including haematological parameters. Full blood count (FBC) parameters of a total of 60 consecutively-recruited hypertensive subjects and 30 age-matched non-hypertensive controls were studied between June and September, 2018. Ethylene Diamine Tetra Acetic Acid (EDTA) anticoagulated blood and serum from subjects and control participants were analyzed for FBC. The total white cell count (WBC), packed cell volume (PCV) haemoglobin (Hb), neutrophils and eosinophils were significantly lower among hypertensive subjects compared to non-hypertensive controls (p 40-year-old compared to those <40 years of age (p = 0.02 and 0.01) respectively. The RBC count was significantly higher among female compared to male hypertensives (p = 0.05). The haemoglobin and monocyte count were significantly higher among male compared to female hypertensives (p = 0.02 and 0.04) respectively. The monocyte count was significantly higher among hypertensive subjects of Hausa ethnic group compared to Fulani (t = 2.79, p < 0.01). The findings from this study indicates that the WBC, PCV, Hb, neutrophils and eosinophils were significantly lower among hypertensive subjects compared to non-hypertensive controls. Stage of the disease, age, gender and ethnicity had a significant effect on the FBC parameters of the hypertensive patients. There is need to step up public enlightenment programme to educate hypertensive patients on the need for attending clinic regularly for effective follow up. It is recommended that facilities for the routine monitoring of FBC parameters among hypertensive in the area be provided.

There is need to step up public enlightenment programme to educate hypertensive patients on the need for attending clinic regularly for effective follow up. It is recommended that facilities for the routine monitoring of FBC parameters among hypertensive in the area be provided.","PeriodicalId":93480,"journal":{"name":"Open journal of blood diseases","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41730918","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}

Background: Mature red blood cells lack protein synthesis and are unable to restore inactivated enzymes, damaged cytoskeleton and membrane proteins. An oxidation breakdown of band 3 is probably part of the mechanism leading to the generation of a senescent cell antigen. This specific signal serves for the clearance of RBCs by inducing the binding of autologous IgG and C3, leading to phagocytosis. In addition, phosphatidilserin molecules appear in the outer membrane and the CD47 expression diminishes. Methods: Erythrocytes of different ages from whole blood were studied by flow cytometry analysing light scatter proprieties, binding of autologous IgG, C3 complement deposits, externalization of phosphatidylserine and CD47 expression. Dot-plot analysis based on forward scatter versus side scatter parameters showed two RBCs populations of different sizes and density. RBCs were further incubated with Alexa 488 IgG, APC-anti-C3, PE-annexin-V and PE-CD47. The comparison of the values obtained for the different variables studied in SeRBC and YRBC populations was carried out by the Student t-test for matched samples or by the Wilcoxon test (after verification of the normality assumption). Results: The percentage of IgG and C3 positive cells was significantly higher in senescent red blood cells population. The fraction of annexin-V positive RBCs was also larger in SeRBCs while the CD47 expression was lower in this population. Conclusions: These results indicate that flow cytometry allow differenciation of erythrocytes populations of different ages, turning this tool into an useful alternative option to study erythrocyte aging process. These findings will contribute to a better understanding of the process and mechanisms involved in erythrocyte senescence process.

Sickle Cell Disease (SCD) is one of the most common genetic diseases in the world. It is associated with oxidative stress which occurs as a result of HbS unstable character causing a rise in the formation of free radicals. The aim of this study was to determine some antioxidant enzymes activities among patients with SCD. We investigated the superoxide dismutase (SOD), and glutathione peroxidases (GPx) levels among 60 children aged 1 - 14 years with SCD. Twenty-two age-matched non-SCD children served as control. The study subjects were divided into two groups; steady state A (n = 30) and vaso- occlusive crisis (VOC) B (n = 30). The SOD, and GPx levels were significantly lower among the SCD subjects compared to controls (p = 0.000). There were no statistically significant differences in the SOD and GPX levels between sickle cell disease patient in steady state (A) and those in crisis (B) (p = 0.998 and 0.555) respectively. There was a statistically significant difference between the SOD and GPX levels between sickle cell disease patient in steady state (A) and non-sickle cell controls (p = 0.005 and 0.000) respectively as well as between sickle cell disease patient in VOC (B) and non-sickle cell controls (p = 0.000). There were no statistically significant differences in the SOD and GPX levels of sickle disease subjects based on age, gender, maternal level of educational attainment, occupational group and income (p = 0.629 and 0.476; p = 0.382 and 0.417; p = 0.450 and 0.314 and p = 0.397 and 0.762 and p = 0.553 and 0.929) respectively. There were no statistically significant differences in the SOD and GPX levels of sickle disease subjects of Hausa/Fulani extraction versus Yoruba (p = 0.714 and 0.856), between Hausa/Fulani extraction versus Igbo (0.917 and 0.486) and between Yoruba extraction versus Igbo (p = 0.740 and 0.965) respectively. This study confirms that SCD children have lower values of antioxidant enzymes compared to controls. SOD and GPX levels in sickle cell disease patient in steady state and vaso-occlusive crisis are significantly lower compared that of non-sickle cell controls. Patients with SCD may benefit from substances with antioxidant properties which can potentially reduce the complications associated with the disease.
