Background: Thalassemic children develop liver fibrosis because of liver iron overload and hepatitis C virus (HCV) infection. Transient elastography (FibroScan) can be a reliable non-invasive method for evaluating liver fibrosis in thalassemic patients. Treatment with ledipasvir/sofosbuvir (LED/SOF) direct acting antiviral agents can significantly affect liver stiffness measurement (LSM) by FibroScan. Original Research Article Yosef et al.; IBRR, 11(3): 9-17, 2020; Article no.IBRR.60361 10 Aims: To assess liver fibrosis by non-invasive FibroScan through LSM before and after generic LED/SOF therapy in multi-transfused β-thalassemic children infected with HCV. Place and Duration of Study: Pediatric Hematology Unit, Tanta University Hospital, from November 2017 to May 2019. Methodology: Fifty multi-transfused β-thalassemic treatment-naϊve children (aged 12-18 years and weighing ≥35kg) with chronic HCV infection were subjected to clinical evaluation, quantitative HCV PCR assay, FibroScan examination, and calculation of APRI, FIB4 index and AST/ ALT ratio. In addition to standard therapy, generic LED/SOF (90/400 mg) treatment was given for 12 weeks’ duration with follow up for further 12 weeks after end of treatment. Results: A positive HCV PCR was changed into negative for all studied patients starting from week 4 after treatment. There was highly significant reduction in the LSM values by FibroScan in the studied patients after therapy (p-value <0.001) with median reduction of 19.4 %. The significant reduction in LSM values was particularly prominent in patients with significant (F2) and advanced (F3) liver fibrosis stages as well as cirrhotic patients (F4). There was significant reduction in the values of other non-invasive liver fibrosis markers FIB-4 index, APRI score and AST/ ALT ratio (pvalue <0.001, <0.001 and 0.020 respectively) after therapy. Conclusion: Generic LED/SOF therapy for 12 weeks’ duration resulted in eradication of HCV infection that was associated with significant decrease in LSM by FibroScan particularly those with higher baseline liver fibrosis stages.
背景:地中海贫血儿童由于肝铁超载和丙型肝炎病毒(HCV)感染而发生肝纤维化。瞬时弹性成像(FibroScan)是评估地中海贫血患者肝纤维化的一种可靠的无创方法。使用ledipasvir/sofosbuvir (LED/SOF)直接作用抗病毒药物治疗可显著影响FibroScan肝硬度测量(LSM)。原创研究文章Yosef et al.;Ibrr, 11(3): 9-17, 2020;文章no.IBRR。目的:通过LSM无创纤维扫描评估多次输血感染HCV的β-地中海贫血儿童在通用LED/SOF治疗前后的肝纤维化情况。研究地点和时间:2017年11月至2019年5月,坦塔大学附属医院儿科血液科。方法:对50例经多次输血的慢性HCV感染的β-地中海贫血treatment-naϊve患儿(年龄12-18岁,体重≥35kg)进行临床评价、定量HCV PCR检测、FibroScan检查,并计算APRI、FIB4指数和AST/ ALT比值。除标准治疗外,给予通用LED/SOF (90/400 mg)治疗12周,治疗结束后再随访12周。结果:从治疗后第4周开始,所有研究患者的HCV PCR阳性变为阴性。治疗后,纤维扫描的LSM值显著降低(p值<0.001),中位降低率为19.4%。LSM值的显著降低在严重(F2)和晚期(F3)肝纤维化患者以及肝硬化患者(F4)中尤为突出。治疗后其他非侵袭性肝纤维化指标FIB-4指数、APRI评分和AST/ ALT比值均显著降低(p值分别<0.001、<0.001和0.020)。结论:为期12周的通用LED/SOF治疗可根除HCV感染,这与FibroScan的LSM显著降低有关,特别是那些基线肝纤维化分期较高的患者。

Plasmodium falciparum is the most virulent and prevalent malaria parasite in Nigeria .This study aimed to determine the prevalence of malaria infection among patients at General Hospitals in Benue State. A total of 1200 patients were examined in this study. Blood samples were collected by finger prick onto clean slides and into the round sample well of PfRDTs. Thick and thin blood films were prepared for microscopic examination. The overall prevalence of malaria infection was 34.8%. A questionnaire was used to determine some demographic factors. Prevalence of malaria in relation to residence, rural area recorded higher prevalence of 42.2% than urban area with prevalence of 23.8%. Chi square analysis showed a significant difference (p < 0.05) in prevalence in relation to residence. The Prevalence of malaria in relation to age groups, age between 6-10 and 7-15 recorded higher infection rate of 54.5% and 51.5% respectively. While, age group >46 recorded 17.5%. The female patients 36.2% were more infected than the males 33.1%.Patients that had informal education recorded higher prevalence rate of 89.2% and those that are farmers had 57.9%. Chi square analysis however showed that the difference was significant (p < 0.05). A significant Original Research Article Adulugba et al.; IBRR, 11(3): 1-8, 2020; Article no.IBRR.59986 2 difference (P<0.05) was observed between patients that used insecticide spray alone as malaria preventive methods (70.1%) compared to patients that used combined methods of prevention (17.2%). Malaria still remains prevalent among patients in Benue State, Nigeria.

Aim: The study was designed to comparatively assess the degree of fibrinolytic response amongst malaria-positive pregnant women, and non-malaria positive subjects in Rivers State, Nigeria. Methods: The study area covered University of Port Harcourt Teaching Hospital, Port Harcourt [UPTH] and Rivers State University Teaching Hospital, [RSUTH] both in Port Harcourt metropolis Rivers State. It was a cross-sectional study carried out on a total of two hundred and forty female attendees at the obstetrics and gynecology clinics of the two hospitals. The subjects were grouped into three comprising of eighty subjects in each group; malarious pregnant women, nonmalarious pregnant women and apparently healthy non-pregnant women. Venous blood sample measuring 5 milliliter volume was drawn from each subject, The sample was dispensed into two separate EDTA anticoagulant bottles, 3 milliliter and 2 milliliter meant for measuring the levels of markers of Original Research Article Stella et al.; IBRR, 11(2): 34-45, 2020; Article no.IBRR.59396 35 fibrinolysis which were Plasminogen, Plasminogen activator inhibitor-1, Plasminogen activator inhibitor-2, Tissue Plasminogen activator, alpha-2-antiplasmin, D-dimers and fibrinogen, and preparation of blood films for malaria microscopy respectively. Results: Fibrinogen result; 760.44±16.18 ng/ml of malaria-positive pregnant women was elevated compared to the malaria-negative women; 697.70±18.84 ng/ml and the non-pregnant control values of 704.73±15.25 ng/ml. These values were significantly different [P<.011] between the study groups. Results of tissue plasminogen activator [tPA]; 46.39±2.69 ng/ml, D-dimer; 77.64±6.94 ng/ml, plasminogen activator inhibitor-1 [PAI-1]; 89.73±2.14 ng/ml, plasminogen activator inhibitor-2 [PAI2]; 568.00±12.51 ng/ml, plasminogen; 23.82±0.75 ng/ml and 2-antiplasmin; 1314.06±34.64 ng/ml of the malaria-positive pregnant women were significantly different [P=0.0001] from non-positive pregnant women; tPA; 28.87±1.38 ng/ml, D-dimer; 53.90±1.18 ng/ml., PAI-1; 80.00± 1.81 ng/ml, PAI-2; 456.31±5.94 ng/ml, Plasminogen; 16.63±0.67 ng/ml and 2-antiplasmin; 1130.61±29.74 ng/ml . Both results were significantly different [P=0.0001] from the non-pregnant control group; tPA; 31.34±1.64 ng/ml, D-dimer; 30.24±1.04 ng/ml, PAI-1; 65,47±2,33 ng/ml, PAI-2; 427.86±6.95 ng/ml, plasminogen; 16.49±0.04 ng/ml and 2-antiplasmin; 1016.98±24.51 ng/ml. Conclusion: The study witnessed significantly high concentrations of fibrinolytic markers in malariapositive pregnant women. This could be due to compromised endothelial cell function resulting to overproduction of biomarkers of fibrinolysis. The implication is thrombus formation and excessive bleeding in pregnancy which could lead to miscarriages, fetal death or maternal mortality.

Background and Aim: Obstetric complications are part of the leading causes of maternal mortality worldwide. This study was carried out to investigate the effect of   complications on the Prothrombin time (PT), activated partial thromboplastin time (APTT), and platelet count (PLC). Women with obstetric complications were recruited as subjects). Pregnant women without complications were included as controls. Study Design: This is a case-control study. Place and Duration of Study: The study took place in Obstetrics and Gynaecology Department of Specialist Hospital Sokoto and the duration was six months. Methodology: Pregnant women aged 18–41 years (mean age 29.5 years) were recruited for the study. The determination of PT and APTT was done by manual methods using commercially prepared Agappe reagent kits, whereas PLC was done by manual methods using a haemocytometer (Improved Neubauer counting chamber). Data were analyzed using SPSS version 23. Results: The results of PT and APTT were significantly higher among women with obstetric complications (14.26±0.23 seconds and 31.32±0.70 second) compared to normal pregnant women (13.00 ± 0.13 seconds and 29.66±0.33) (P<0.05). The PLC was significantly lower among women with obstetric complications compared to women without obstetric complications (P< 0.05).Obstetric complications in subject show a significant association when compared with PT and APTT (P< 0.05). The age group of subjects shows a significant association when compared with APTT (P< 0.05). Conclusion: Findings from this study have shown that obstetric complications causes decrease in platelet count and prolongation in PT and APTT. There is need to assess the PT, APTT and Platelet count routinely for pregnant women to improve the ante-natal care in Specialist Hospital Sokoto.
背景和目的:产科并发症是全世界孕产妇死亡的主要原因之一。本研究旨在探讨并发症对凝血酶原时间(PT)、活化部分凝血活素时间(APTT)和血小板计数(PLC)的影响。有产科并发症的妇女被招募为研究对象)。无并发症的孕妇作为对照。研究设计:这是一项病例对照研究。研究地点和持续时间:研究在索科托专科医院妇产科进行,持续时间为6个月。方法:研究招募年龄在18-41岁(平均年龄29.5岁)的孕妇。PT和APTT的测定采用人工方法,使用商业制备的Agappe试剂盒,而PLC的测定采用人工方法,使用血细胞计(改进的Neubauer计数室)。数据分析采用SPSS version 23。结果:产科并发症组PT、APTT评分分别为14.26±0.23秒和31.32±0.70秒,显著高于正常妊娠组(13.00±0.13秒和29.66±0.33秒),差异有统计学意义(P<0.05)。有产科并发症妇女的PLC明显低于无产科并发症妇女(P< 0.05)。与PT和APTT相比,受试者的产科并发症有显著相关性(P< 0.05)。与APTT比较,各年龄组间存在显著相关性(P< 0.05)。结论:本研究结果表明,产科并发症导致血小板计数下降,延长PT和APTT时间。有必要对孕妇的PT、APTT和血小板计数进行常规评估,以改善索科托专科医院的产前护理。

Data were analyzed using SPSS version 23. \u0000Results: The results of PT and APTT were significantly higher among women with obstetric complications (14.26±0.23 seconds and 31.32±0.70 second) compared to normal pregnant women (13.00 ± 0.13 seconds and 29.66±0.33) (P<0.05). The PLC was significantly lower among women with obstetric complications compared to women without obstetric complications (P< 0.05).Obstetric complications in subject show a significant association when compared with PT and APTT (P< 0.05). The age group of subjects shows a significant association when compared with APTT (P< 0.05). \u0000Conclusion: Findings from this study have shown that obstetric complications causes decrease in platelet count and prolongation in PT and APTT. There is need to assess the PT, APTT and Platelet count routinely for pregnant women to improve the ante-natal care in Specialist Hospital Sokoto.","PeriodicalId":13659,"journal":{"name":"International Blood Research & Reviews","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82526742","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}

Blood banks in sub-Saharan Africa regularly face shortages of blood products (PS). Several factors are responsible for this, including transfusion-transmissible infections (ITT) and deficiencies in the transfusion system. This study aims to determine the prevalence and the various reasons for rejection at the blood bank of the Central Hospital of Yaoundé. We first conducted a retrospective study at the blood bank of the Central Hospital of Yaoundé for 12 months between January 01, 2014 and December 31, 2014.Secondly, we carried out a prospective study in October 2015. Five milliliters (05 ml) of venous blood were taken from each participant in a tube without anticoagulant; patient samples were stored at -24°C. A rapid screening test and ELISA were used to test for HIV, HCV, HBs and syphilis on the samples taken. Approximately 15,028 bags of whole blood were drawn in 2014, of which 3,688 bags were rejected. This equates to a rejection rate of 24.54%. Discards for non-infectious reasons represented 3.51% and rejections for infectious reasons 21.03%. During the prospective study, among those selected, there were 95.74% men and 4.26% women. The average age of the participants was 30 years. Among the 705 people in this investigation, 185 blood bags were rejected. Infectious causes represented 22.55% (Hepatitis B and C, HIV and syphilis with a respective prevalence of 9.08%, 0.71% 6.95% and 5.82%) and nonOriginal Research Article Bernard; IBRR, 11(2): 15-22, 2020; Article no.IBRR.57155 16 infectious causes represented 3.68 % (clots, insufficient volume of PST, hemolysis and expiration with a respective prevalence of: 1.84%, 0.71 0.14% and 0.99%).The association between rejection of blood bags and qualitative variables was assessed. There emerged a significant association between the risk of rejection of a blood bag and the type of donor; condom use, number of partners, history of STIs. At the Yaoundé Central Hospital blood bank, the reasons for rejecting blood bags are divided into two categories: Mainly infectious and non-infectious. Also, certain risk variables such as not using a condom, multiple sexual partners and a history of STIs are risk factors that can encourage rejection of blood bags.
撒哈拉以南非洲的血库经常面临血液制品短缺的问题。造成这种情况的因素有几个,包括输血传播感染(ITT)和输血系统缺陷。本研究旨在了解雅温德市中心医院血库血液排斥反应的发生率及各种原因。我们首先于2014年1月1日至2014年12月31日在雅温得中心医院血库进行了为期12个月的回顾性研究。其次,我们在2015年10月进行了前瞻性研究。5毫升(05毫升)静脉血从每个参与者在不使用抗凝剂的试管中取出;患者标本保存于-24°C。采用快速筛选试验和酶联免疫吸附试验对采集的样本进行HIV、HCV、HBs和梅毒检测。2014年抽取了15028袋全血,其中3688袋被拒绝。这相当于24.54%的拒绝率。非感染原因报废占3.51%,感染原因拒收占21.03%。在前瞻性研究中,被选者中男性占95.74%,女性占4.26%。参与者的平均年龄为30岁。在此次调查的705人中,有185个血袋被拒收。感染原因占22.55%(乙肝、丙肝、HIV、梅毒患病率分别为9.08%、0.71%、6.95%和5.82%),非原创性研究伯纳德;国际生物医学杂志,11(2):15-22,2020;文章no.IBRR。57155 16种感染原因占3.68%(凝块、PST容量不足、溶血和呼气,患病率分别为1.84%、0.71、0.14%和0.99%)。评估血袋拒收与定性变量之间的关系。血袋的排斥风险与捐赠者的类型之间存在显著关联;避孕套使用情况,性伴侣数量,性传播感染史。在雅温得中心医院血库,拒绝血袋的原因分为两类:主要是传染性和非传染性。此外,某些风险变量,如不使用避孕套、多个性伴侣和性传播感染史,都是可能鼓励排斥血袋的风险因素。

Sickle cell is haematological disorder (haematology is a study of blood in health and diseases) which may lead to an organ damage, heart strokes and serious complications. It may also reduce human life span. Most of the sickle cells are observed in new born babies. At the start of sickle cells in human people though it’s a kind of feature in tribal people but it has spread over the world. Sickle cell Symptoms are observed in human beings as episodes of pains (crisis), Vision problems, swelling of hands and Feet. Sickle Cell Disease (SCD) can harm patient’s spleen (slightly pain at left Ribs). If one organ is affected in human body, then slowly it affects the entire body by spreading into Brain, Lungs, Heart, Liver, Kidneys, Joints, Eyes, Penis, Skin or Bone. This paper is aimed at presenting the complete details of the SCD with its properties, symptoms, signs, treatment for this disease. This is also a comprehensive study and characteristics of this disease with other similar diseases. The technological implications and usage in the field of SCD for better accuracy of identification of the disease is presented.
镰状细胞病是一种血液学疾病(血液学是对健康和疾病中的血液的研究),可能导致器官损伤、心脏病和严重并发症。它还可能缩短人类的寿命。大多数镰状细胞见于新生儿。在人类的镰状细胞出现之初,虽然这是部落人群的一种特征,但它已经传播到世界各地。镰状细胞症状在人类中被观察到为阵发性疼痛(危象)、视力问题、手脚肿胀。镰状细胞病(SCD)可损害患者的脾脏(左肋骨轻微疼痛)。如果人体的一个器官受到影响,那么慢慢地,它会通过扩散到大脑、肺、心脏、肝脏、肾脏、关节、眼睛、阴茎、皮肤或骨骼来影响整个身体。本文旨在介绍SCD的完整细节,包括其特性,症状,体征,治疗方法。这也是综合研究本病与其他类似疾病的特点。介绍了SCD领域的技术含义和应用,以提高疾病识别的准确性。

Background & Aims: Acute coronary syndrome is one of the leading causes of morbidity and mortality in the world and platelet hyperactivity with local platelet activation plays a crucial role in its genesis. As there is discrepancy regarding the significance of deranged platelet parameters, we aimed to study the role of platelet volume indices in the spectrum of coronary artery syndrome and to correlate them clinically. Study Design: The study was conducted by collecting the data of patients with Myocardial infarction from the Cardiac care unit registry along with their clinical history and investigations. Stable coronary artery cases were collected from the Catheterization Lab and compared with Age and Sex matched controls. All CBCs of the above groups were processed by a 5-part counter and the data generated was transferred to a master chart for statistical analysis. Place and Duration of study: The study was conducted in the Central Laboratory & Department of Pathology at D.Y. Patil Hospital, Navi Mumbai, India in collaboration with the Cardiac Care Unit and Catheterisation Lab of the hospital for a period of two years. Original Research Article Paramjit et al.; IBRR, 11(2): 1-5, 2020; Article no.IBRR.55817 2 Methods: A total of 122 cases were studied and grouped into 5 groups according to presentation and the platelet volume indices of these were compared with 38 matched controls and statistically analysed. Results: Mean Platelet Volume and Platelet Distribution Width of patients with ST elevation Myocardial Infarction (STEMI) and Non ST elevation Myocardial Infarction(NSTEMI) were increased marginally in number when compared to Stable Coronary Artery Disease(SCAD) and Control group, however this was not statistically significant. Platelet Large Cell Ratio (PLCR) was significantly raised in STEMI cases only (P = 0.09), so it may prove to be a better marker for the disease (P = 0.09). Platelet counts in various groups when compared with controls gave inconsistent results i.e SCAD vs Control significantly decreased (P = 0.07) and STEMI vs Control significantly increased (P = 0.01). Conclusion: The platelet volume indices in suspected acute coronary syndrome cases showed various changes, but present data failed to be diagnostically significant. However this data may later help to characterise further relationship between Acute coronary syndrome and platelet function in subsequent studies.
背景与目的:急性冠状动脉综合征是世界上发病率和死亡率的主要原因之一,血小板过度活跃伴局部血小板活化在其发病中起着至关重要的作用。由于血小板参数紊乱的意义存在差异,我们旨在研究血小板体积指数在冠状动脉综合征频谱中的作用,并在临床上将它们联系起来。研究设计:本研究通过收集心脏护理单位登记的心肌梗死患者的资料以及他们的临床病史和调查来进行。从导管实验室收集稳定冠状动脉病例,并与年龄和性别匹配的对照组进行比较。以上各组CBCs均采用五分式计数器处理,产生的数据移入主图进行统计分析。研究地点和时间:该研究在印度孟买D.Y. Patil医院的中心实验室和病理学部与医院的心脏护理科和导管实验室合作进行,为期两年。Paramjit et al.;中国生物医学杂志,11(2):1-5,2020;文章no.IBRR。方法:对122例患者进行研究,按临床表现分为5组,与38例对照者进行血小板体积指数的比较,并进行统计学分析。结果:ST段抬高型心肌梗死(STEMI)和非ST段抬高型心肌梗死(NSTEMI)患者的平均血小板体积和血小板分布宽度与稳定型冠状动脉疾病(SCAD)和对照组相比,数量略有增加,但无统计学意义。血小板大细胞比率(PLCR)仅在STEMI病例中显著升高(P = 0.09),因此它可能是更好的疾病标志物(P = 0.09)。与对照组相比,不同组的血小板计数结果不一致,即SCAD组与对照组相比显著降低(P = 0.07), STEMI组与对照组相比显著增加(P = 0.01)。结论:疑似急性冠状动脉综合征患者血小板体积指标有不同程度的变化,但目前的资料对诊断意义不大。然而,这些数据可能有助于在随后的研究中进一步确定急性冠状动脉综合征和血小板功能之间的关系。

In order to prevent post transfusion alloimmunization, it is essential to give recipients compatible blood products. However in countries with limited income, blood grouping is limited to the ABO system and to the D antigen of the Rhesus system; however, there are other immunogenic antigens such as C, c, E, e and K to name a few. This should be the reason why a retrospective study by Tayou et al. at the blood bank of the University Hospital Center (CHU) of Yaoundé in 2009 on the erythrocyte phenotype in the donor and recipient of blood product only reported to us that data relate to the erythrocyte blood group system ABO and the Rh 1 antigen. We therefore found it expedient to carry out erythrocyte phenotyping in the ABO, RH and KELL blood group systems in the donor and recipient of blood products at the CHU of Yaoundé. A descriptive, transversal and prospective study was carried out at the blood bank of the CHU of Yaoundé over 6 months, from June 1, 2017 to December 31, 2017. It was interested in the donorOriginal Research Article Chemegni et al.; IBRR, 11(1): 31-37, 2020; Article no.IBRR.56051 32 recipient couples of blood within which the recipient was a patient hospitalized at the CHU. Laboratory analyses of donor and recipient blood samples have allowed us to have the phenotypes in the ABO, RH, and KELL blood group systems. In the ABO system, the phenotypes obtained were 4: A1, A1B, B and O at 27.27%, 2.27%, 13.64% and 56.82% respectively among donors and 31.82%, 2.27%, 13.64% and 52.27% among recipients. In addition, from the Rhesus system, there were 5 phenotypes in donors: D + C + E + c + e +, D + C + E-c + e +, D + C-E + c + e +, D + CE-c + e +, DCE-c + e + respectively at 2.27%, 11.36%, 9.09%, 75.00% and 2.27% and in recipients 4 phenotypes, namely: D + C + E + c + e +, D + C-E + c + e +, D + CE-c + e +, DCE-c + e + at 15.91%, 27.27%, 54.55% and 2.27% respectively. In the KELL system, the K antigen was present in 4.55% of donors and 2.27% of recipients. An antigen supply from the donor to the recipient was evaluated at 6.82% for C, 4.54% for E, 2.27% for K and 2.27% for K, C, E at the same time. This gave us an estimate of the average risk of alloimmunization at 15.9%. Erythrocyte phenotyping would therefore be of major benefit during blood transfusion and would considerably prevent the risks of alloimmunization.
为了防止输血后同种异体免疫,必须向受者提供相容的血液制品。然而,在收入有限的国家,血型仅限于ABO系统和恒河猴系统的D抗原;然而,还有其他免疫原性抗原,如C、C、E、E和K等。这应该就是为什么2009年,Tayou等人在雅温市大学医院中心血库对供血者和受血者的红细胞表型进行回顾性研究时,只向我们报告了红细胞血型系统ABO和Rh 1抗原的数据。因此,我们发现在雅温德医院血液制品供者和受者的ABO、RH和KELL血型系统中进行红细胞表型分析是有利的。本研究于2017年6月1日至2017年12月31日6个多月的时间内,在雅温得市CHU血库进行了一项描述性、横向、前瞻性研究。它对捐赠者的原创研究文章Chemegni等人感兴趣;国际生物医学杂志,11(1):31-37,2020;文章no.IBRR。56051 32对受血人,其中受血人是在保健所住院的病人。供体和受体血液样本的实验室分析使我们能够在ABO, RH和KELL血型系统中获得表型。在ABO系统中,获得的表型为4种:A1、A1B、B和O,供者分别占27.27%、2.27%、13.64%和56.82%,受体占31.82%、2.27%、13.64%和52.27%。此外,从恒河系统,捐赠者有5表型:D + C + E + E C + +,英汉+ E D + C + +, D +汉英+ C + E + D + CE-c + E + DCE-c + E +分别为2.27%,11.36%,9.09%,75.00%和2.27%,而接受者4表型,即:D + C + E + E C + +, D +汉英+ C + E + D + CE-c + E + DCE-c + E + 15.91%,分别为27.27%、54.55%和2.27%。在KELL系统中,4.55%的供体和2.27%的受体存在K抗原。从供体到受体的抗原供给率分别为C的6.82%、E的4.54%、K的2.27%和K、C、E的2.27%。这使我们估计同种异体免疫的平均风险为15.9%。因此,红细胞表型在输血过程中具有重要的益处,并可大大预防同种异体免疫的风险。

An antigen supply from the donor to the recipient was evaluated at 6.82% for C, 4.54% for E, 2.27% for K and 2.27% for K, C, E at the same time. This gave us an estimate of the average risk of alloimmunization at 15.9%. Erythrocyte phenotyping would therefore be of major benefit during blood transfusion and would considerably prevent the risks of alloimmunization.","PeriodicalId":13659,"journal":{"name":"International Blood Research & Reviews","volume":"27 1","pages":"31-37"},"PeriodicalIF":0.0,"publicationDate":"2020-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78695111","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: Sickle Cell Disease (SCD) is a hereditary haemoglobinopathy that has been related with significant mortality in Nigeria. Knowledge on cause, prevention and risk factors are important for adequate control of the occurrence of SCD. Methods: A cross sectional study on the awareness of SCD was carried out among undergraduate students in Port Harcourt, Nigeria. A structured questionnaire was interviewer-administered to 146 students. Results: The study showed that 97.9% claim to have heard about sickle cell, while 68.5% indicated that the source of information on sickle cell was in school. One hundred and twenty-seven (87%) indicated that SCD describes abnormal blood cells. In 68.5% the source of information on SCD was in school. Only 42% had a good awareness on SCD. Students of male gender, of less than 20 years, with less average family income were more likely to have poor awareness of SCD. Conclusion: The study shows the need for improved awareness on SCD and increased awareness campaigns on every available media platform.
背景:镰状细胞病(SCD)是一种遗传性血红蛋白病,在尼日利亚与显著的死亡率相关。了解病因、预防和危险因素对于充分控制SCD的发生非常重要。方法:对尼日利亚哈科特港的大学生进行SCD认知的横断面调查。对146名学生进行了结构化问卷调查。结果:97.9%的人表示听说过镰状细胞,68.5%的人表示镰状细胞的信息来源是学校。127例(87%)提示SCD表现为血细胞异常。68.5%的儿童残疾信息来自学校。只有42%的人对SCD有良好的认识。年龄小于20岁、家庭平均收入较低的男性学生对SCD的认识较差的可能性更大。结论:该研究表明,需要提高对SCD的认识,并在每个可用的媒体平台上增加认识活动。

Introduction: Haemostasis refers to the arrest of bleeding due to vascular damage and involves the intrinsic and extrinsic coagulation pathways which converge at the point of fibrin activation to stop or minimize blood loss. Amaranthus hybridus contains a while range of nutritional, chemical and phytochemical constituents which gives it wide range of applications in folk medicine. Aim: To evaluate the effects of ethanolic extracts of Amaranthus hybridus on blood platelet count, prothrombin time (PT) and activated partial thromboplastin time (APTT) using Wistar rat models. Methodology: Twenty Four (24) adult male Wistar rats were used for the study. The animals were randomly divided into three (3) groups of eight (8) animals each. Oral administration of distilled water for the control group and ethanolic extracts of Amaranthus hybridus at 30 and 60 mg/kg lasted for twenty eight (28) days. Platelet count, prothrombin time (PT) and activated partial thromboplastin time (APTT) were determined using standard laboratory methods. Results: Ethanolic extracts of Amaranthus hybridus significantly increased platelet count at 30 mg and 60 mg/kg compared to the control animals (p<0.05). Also, it significantly reduced prothrombin time and activated partial thromboplastin time at 30 and 60 mg/kg in a dose dependent manner compared to control animals (P<0.05).   Conclusion: The study shows that ethanolic extract of Amaranthus hybridus may have enhanced haemostasis as demonstrated by increased platelet count and reduced prothrombin (PT) and activated partial thromboplastin time (APTT) time.
简介:止血是指血管损伤引起的出血的停止,涉及内在和外在凝血途径,它们在纤维蛋白激活点聚集,以停止或减少失血。苋菜含有丰富的营养、化学和植物化学成分,在民间医药中有着广泛的应用。目的:采用Wistar大鼠模型,观察苋菜乙醇提取物对大鼠血小板计数、凝血酶原时间(PT)和活化部分凝血活酶时间(APTT)的影响。方法:采用成年雄性Wistar大鼠24只。这些动物被随机分成三组,每组8只。对照组灌胃蒸馏水,苋菜乙醇提取物灌胃30、60 mg/kg,连续灌胃28 d。血小板计数,凝血酶原时间(PT)和活化部分凝血活素时间(APTT)采用标准实验室方法测定。结果:紫花苋乙醇提取物在30 mg和60 mg/kg组与对照组相比,血小板计数显著增加(p<0.05)。此外,与对照动物相比,30和60 mg/kg的剂量依赖性显著降低了凝血酶原时间和激活部分凝血活酶时间(P<0.05)。结论:紫花苋醇提物可能通过增加血小板计数、降低凝血酶原(PT)和激活部分凝血活酶时间(APTT)来增强止血作用。
