Ann Med Surg (Lond) 2024; 86:4634-4642. [PMID: 39118706 PMCID: PMC11305715 DOI: 10.1097/ms9.0000000000002302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Accepted: 06/13/2024] [Indexed: 08/10/2024] Open
Abstract
The COVID-19 pandemic has brought to light the intricate relationship between platelets, soluble platelet selectin (sP-selectin), and disease pathogenesis. Platelets, traditionally recognized for their role in hemostasis, have emerged as key contributors to the immunothrombotic complications observed in COVID-19 patients. Concurrently, elevated levels of sP-selectin, indicative of platelet activation and endothelial injury, have been consistently identified in COVID-19 patients and have shown associations with disease severity and adverse outcomes. This multifaceted connection underscores the pivotal role of platelets and sP-selectin in orchestrating thromboinflammation, vascular dysfunction, and disease progression in COVID-19. Platelet activation triggers the release of inflammatory mediators and promotes platelet-leukocyte interactions, amplifying the systemic inflammatory response and exacerbating endothelial injury. Additionally, platelet-derived factors contribute to microvascular thrombosis, further exacerbating tissue damage and organ dysfunction in severe COVID-19. Elevated sP-selectin levels serve as biomarkers for disease severity and prognostication, aiding in risk stratification and early identification of patients at higher risk of adverse outcomes. Therapeutic strategies targeting platelet dysfunction and sP-selectin-mediated pathways hold promise in mitigating thromboinflammation and improving outcomes in COVID-19 patients. Antiplatelet agents, platelet inhibitors, and anti-inflammatory therapies represent potential interventions to attenuate platelet activation, inhibit platelet-leukocyte interactions, and alleviate endothelial dysfunction. A comprehensive understanding of the multifaceted connection between platelets, sP-selectin, and COVID-19 pathogenesis offers opportunities for tailored therapeutic approaches aimed at mitigating thromboinflammation and improving patient outcomes in this complex and challenging clinical setting.

Abstract
Background Rate and pattern of under-five mortality is a reflection of a society's healthcare system and quality of life. This study is aimed at reviewing the causes of infants and under-five morbidity and mortality in Calabar, Southern Nigeria. Methods This study used retrospective descriptive cross-sectional design. We did a retrospective collation of data on under-five morbidity and mortality from 2012 to 2017 of under-five patients admitted or died while in admission in University of Calabar Teaching Hospital. The causes of morbidity and mortality were reported based on International Classification of Diseases 10 (ICD-10). The morbidity, mortality and fatality rates were computed. Results A total of 11,416 under-five admissions and 391 deaths were recorded within the study period giving a fatality rate of 3.4%. Age 1-4 years category represented 50.5% of the admissions while infants (<1 year) constitute majority of the deaths (64.7%). There were 5652 infant admissions and 253 infant deaths giving fatality rate of 4.5% within the study period. Males constituted majority (55.8%) of under-five morbidity whereas females constituted majority (51.2%) of the deaths. Conditions originating from perinatal period; and infectious and parasitic diseases were the leading broad cause of under-five mortality. Specific disease analysis showed sepsis/septicemia; congenital infectious and parasitic diseases; slow fetal growth, malnutrition and short gestation as the chief causes of both infant and under-five mortality. Conclusion The leading causes of under-five deaths in the studied population are amenable. Improved healthcare and antenatal will be of immense benefit.

Seroprevalence of Transfusion-Transmissible Infections among Family Replacement Donors and Voluntary Non-Remunerated Blood Donors During the COVID-19 Pandemic in Sub Saharan Africa. Mediterr J Hematol Infect Dis 2024; 16:e2024008. [PMID: 38223484 PMCID: PMC10786141 DOI: 10.4084/mjhid.2024.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 12/10/2023] [Indexed: 01/16/2024] Open
Abstract
Introduction : According to WHO, regular, voluntary, unpaid blood donors are the safest group of donors, as they have the lowest prevalence of blood transmitted infections. However, family/replacement blood donors is widely used in sub Saharan Africa and this practice was exacerbated during the COVID 19 pandemic. This study aimed to compare the seroprevalence of infectious markers in family replacement blood donors and voluntary non-remunerated blood donors during the COVID 19 pandemic in a country of sub Saharan Africa.
Materials and Methods
Blood donors received at the National Centre of Blood Transfusion (NBTC) of Dakar from August 1st to October 31th 2021, were included in this study. All donors completed a pre-donation questionnaire. Donors identity, epidemiological parameters, reasons for donation and laboratory results were collected in the Inlog® software of the NBTC. The serological tests for HBV, HIV and HCV were performed with chemiluminescence technology. The Rapid Plasma Reagent test was used to find out treponemal antibodies. The determination of ABO and Rh blood groups was performed using monoclonal antisera following classical hemagglutination test on a plate.
Results
A total of 5002 donors were collected during this COVID-19 pandemic period. Blood family/replacement donors represented 54.0% and new voluntary donors represented 52.6%. Comparison of HIV, HCV and syphilis markers seroprevalence showed no statistically significant difference between new voluntary donors and new family replacement donors (p>0.05). However, for HBV the seroprevalence was significantly higher in new family replacement donors (p=0,002).
Conclusion
The proper supply of blood was impacted by the COVID-19 pandemic meanwhile replacement donations had contributed to limiting the damage observed with blood shortages. However, the significant differences noted on the seroprevalences of transfusion-transmissible infections between voluntary non-paid donors and family/replacement donors strengthens WHO recommendations for the selection of volunteer non-paid donors to lower transfusion-transmissible HBV in sub Saharan Africa.

Abstract
Blood centers, which are arguably the backbone of every hospital, depend on blood donors for a constant and regular supply of blood. Like many other fields, the COVID-19 pandemic severely affected blood donations. In this article, we aim to systematically search the studies done on blood donation during the COVID-19 pandemic period, analyze the pandemic's effect on blood donation, and examine the methodology used to overcome the problem. We performed a systematic review and meta-analysis to investigate the effect of the COVID-19 pandemic on blood donation. Two independent reviewers searched different databases, such as PubMed, ProQuest, Scopus, and Google Scholar. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Joanna Briggs Institute critical appraisal checklist for overall study characteristics. We included a total of 15 studies. There was an overall decrease in blood donation of 25%, with some regions showing a decrease of as much as 71%. However, some regions were able to experience a 2-10% increase in blood donation after taking stringent and early measures to prevent such decreases. The COVID-19 pandemic and consequent lockdown greatly affected blood transfusion services, resulting in a progressive decline in blood donations that threatened the lives of many patients who were fully dependent on blood transfusion. However, by making appropriate and early decisions and taking action, policymakers and the rest of society can prevent such shortages, potentially saving millions of lives.

Abstract
The novel coronavirus (SARS-CoV-2) outbreak exerted a serious effect on healthcare. Between 1st of January and May 31, 2020 due to the special regulations in Hungary, the number of reported COVID-19 infections were relatively low (3876 cases). The inpatient and outpatient care and the blood supply were significantly affected by the implemented regulations. The aim of this study was to evaluate the use of blood products amid the first five months of the pandemic situation. This investigation has observed a significant reduction of hospitalizations (37.35%). Analyzing individually the included units, pre-transfusion hemoglobin concentrations of transfused patients presented slight modifications, which were not statistically significant. The special regulations resulted major changes in the frequency of diagnoses at admissions in case of the Department of Surgery, while in case of the other specialities (Division of Hematology and Department of Anesthesiology and Intensive Therapy), there were no major changes compared to pre-pandemic period. Considering each department separately, transfused red blood cell concentrates (RBC) per patient, and the proportion of transfused patients did not change significantly. However, the combination of these modifications resulted in the significant decrease in RBC transfusions (p < 0.0001) compared to the pre-pandemic baseline. With regard to platelet and fresh frozen plasma (FFP), their usage was significantly reduced (44.40% platelet concentrates and 34.27% FFP). Our results indicate that the pandemic had an important effect on the blood product usage at the included departments by introducing different patient care policies and the temporary deferral of the elective surgical interventions. Despite the challenging circumstances of blood collection and blood product supply, the hospitalized patients received adequate care.

Abstract
Background The coronavirus pandemic confronted blood transfusion services with major challenges. The present study was conducted to explore the effect of the COVID-19 pandemic on blood transfusion services including seroprevalence of transfusion-transmitted infections. Material and Methods A retrospective cross-sectional study was conducted and data on blood donation, utilization, camps, plateletpheresis and seroprevalence of transfusion-transmitted infections (TTI) was retrieved from software from March to September 2020 and 2021 and compared with corresponding time periods of three preceding non-pandemic years. Results There was a decline of 53.79% and 34.4% in blood donations in 2020 and 2021 respectively with a significant reduction in voluntary donations from 91.8% in the pre-pandemic period to 72.2% in 2020 and 77.7% in 2021. Replacement donors increased by 60.81% and 72.89% in 2020 and 2021 respectively. There was a decline of 48.4% in the number of plateletpheresis procedures in 2020 which increased in 2021 during the dengue outbreak. The decline in total blood donations and issue of packed red blood cells was statistically significant but supply and demand were balanced with no deficit. TTI seroprevalence increased from 1.01% to 1.49%(p<0.001) and 1.51%(p<0.001) in 2020 and 2021 respectively. Replacement donors showed a significantly higher TTI prevalence as compared to voluntary donors(p<0.001). A significant increase in prevalence was observed for Syphilis (0.4%) in 2020 and HBsAg (0.54%), HCV(0.63%) and syphilis (0.25%) in 2021. Conclusion The potential consequences of the COVID-19 pandemic on blood safety cannot be undermined. Developing a strong database of regular voluntary donors can be instrumental in dealing with future waves and surges in infections.

Abstract
Purpose The coronavirus disease 2019 (COVID-19) pandemic disrupted the supply of blood globally, resulting in numerous studies focusing on the challenges in maintaining blood supply, and the responses to it, in countries with a mixed blood donation model. This study explored blood donation challenges and mobilization mechanisms in North China, which employs a non-remunerative donation model, during the COVID-19 pandemic’s first wave. Materials and Methods A qualitative approach was adopted to investigate blood donation practices in Chengde from April to June 2020. Data were collected from eight blood donors, six potential donors, three blood donation station leaders, and two government officials, through semi-structured interviews. Results The major challenge for blood supply was decreased blood donations, owing to lockdown restrictions, and individual and familial apprehensions. Mobilization mechanisms included bureaucratic and ideological mobilization. However, although group blood donation alleviates the pressure on supply chains during emergencies, it is detrimental to the cultivation of civic engagement in the long run. Conclusion This study contributes to the understanding of how countries with uncompensated blood donation models respond to public health emergencies. It suggests that striking a balance between the society’s and the state’s perception of blood donation would allow the state to incorporate the different “voices” of society, and devise an inclusive blood donation policy.

Abstract
Introduction After the World Health Organization declared COVID-19 a pandemic, a hand full of cases and deaths have been recorded globally, Nigeria inclusive. Methods A retrospective analysis of the COVID-19 weekly disease update report by the Nigeria Centre for Disease Control (NCDC) covering February 29, 2020 (Week 9) and March 28, 2021 (Week 12) was adopted for this study. Data were curated from the NCDC database. Results As of March 28, 2021, Nigeria is the 5th most affected African country and the 77th most affected country globally with 162,593 COVID-19 cases and 2,048 COVID-19 related deaths. COVID-19 has been reported in all 36 States and the Federal Capital Territory. However, Lagos has remained the epicenter of the pandemic accounting for 35.4% of the pandemic in Nigeria while Kogi State is the least affected State (0.003%). The trend showed male predilection while the age bracket 35-39 years was the most affected. The attack rate was found to be 78.8 per 100,000 of the population while the cumulative death per 100,000 of the population was found to be 1.0. The case fatality rate was found to be 1.30. Approximately 1,778,105 COVID-19 tests have been performed while 923,623 doses of vaccine have been administered. Conclusions COVID-19 has been reported in all states in Nigeria as well as the Federal Capital Territory with many of the cases involving males. The case trend showed a bimodal form indicating a second wave occurrence. Nigeria government has initiated some combative measures as well as vaccine initiation.

Abstract
OBJECTIVE This work aimed to establish the effects of the COVID-19 pandemic on blood collection and blood product usage at the end of the first year. BACKGROUND The arrival of SARS-CoV-2 to Colombia on March 6, 2020, triggered closure of borders and mandatory lockdown from March 23, 2020. METHODS/MATERIALS The Colombian National Institute of Health administers the National database of confirmed cases of SARS-CoV-2 and the National Haemovigilance System. We examined positive SARS-CoV-2 cases identified between March 6, 2020, and March 6, 2021, using positive RT-PCR testing (72.8%) or reactive antigen (27.2%). We also analysed accepted and deferred donors' information provided by 100% of blood banks and transfused patients notified by 83% of health care facilities nationwide, between March 1, 2019, to February 28, 2021. RESULTS Colombia registered 2 273 245 SARS-CoV-2 cases. From these, 60 412 people died from COVID-19 (2.7%) and 2 172 418 individuals recovered (95.6%). There were 11 659 216 SARS-CoV-2 processed samples nationwide. People between the ages of 20 and 39 years concentrated 44.4% of the SARS-CoV-2 cases. There were 773 569 blood donations, mainly from a 20-39-year-old population (60.5%). The pandemic caused a reduction of 155 393 blood donations (16.7%) and 51 823 total deferrals (33.7%). An 18.4% drop in volunteer donors and a 37.3% increase in donations from family/replacements members were observed. There were 399 453 transfused patients and 1 179 895 blood components administered (-8.7% and - 13.9% compared to March 2019-February 2020). CONCLUSION Mandatory lockdowns in Colombia decreased blood collection and usage, resulting in a reduction of blood components transfused to individual patients.

Abstract
Introduction The safety of a blood transfusion practice is anchored on safe blood from a healthy donor, while further protecting the donor from future harm. This study aimed to evaluate the hematological parameters of blood donors in view of their donor category to aid in assessing the safety threshold in terms of donation frequency. Methods This study made use of the descriptive cross-sectional design. The blood donors were bled and their samples analyzed using a hematology autoanalyzer. Results A total of 178 male blood donors were recruited. Most of the donors were aged 18 to 39 years and were mostly students. A greater part of them were repeat donors who had donated blood more than four times. First- and second-time donors constituted the majority of the voluntary donors. While the total red cell count was significantly lower in repeat third-time donors, the hemoglobin and hematocrit of the first-time donors were significantly higher than those of the repeat fourth-time donors. The mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) of the first-time donors were significantly higher than those of the repeat fifth-time donors. The red cell distribution width (RDW) and mean platelet volume (MPV) were significantly lower in the first-time donors from those of the sixth- and seventh-time donors, respectively. Most of the fifth-time donors have subclinical anemia. There was more subclinical anemia in commercial donors than in voluntary donors. Conclusion Repeat donors more than fifth-time donors are at risk of donation-induced iron deficiency anemia.

Hematol Transfus Cell Ther 2021; 43:119-125. [PMID: 33714719 PMCID: PMC8211632 DOI: 10.1016/j.htct.2021.01.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 11/13/2020] [Accepted: 01/07/2021] [Indexed: 02/07/2023] Open
Abstract
Introduction The West African region has been lagging in terms of the availability of, and accessibility to, safe blood. According to the 2016 World Health Organization (WHO) Global Status Report on Blood Safety and Availability, none of the West African countries met the WHO benchmark of 10 blood units per 1000 inhabitants. This study is aimed at discussing the blood transfusion status of West African countries in the pre-COVID-19 period and analyze the capacity to respond to the COVID-19 blood crisis, as well as to outline the panacea. Methods Secondary data were extracted from published reports, journal articles and web pages, reviewed and analyzed. Result All the West African countries have recorded confirmed COVID-19 cases and deaths. The confirmed cases have reached 55,697, with 1069 deaths and a fatality rate of 1.9%, as of June 17, 2020. The assessed countries lagged in most of the WHO benchmarks for effective blood transfusion services. Conclusion Blood transfusion services in the West African region lacked the basic benchmark practice and policy, are not coordinated and may find it hard to tackle the blood transfusion crisis created by the COVID-19 pandemic.
