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.","PeriodicalId":13659,"journal":{"name":"International Blood Research & Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81171346","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}

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.","PeriodicalId":13659,"journal":{"name":"International Blood Research & Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73116215","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}

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.

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.","PeriodicalId":13659,"journal":{"name":"International Blood Research & Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86241469","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}

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.

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%.
