Concerted efforts have been made by scientists over the last decades in elucidating the molecular mechanisms leading to myeloproliferative neoplasms. The identification of oncogenic mutations in signal transduction pathways revealed the role of specific pathways in inducing excessive proliferation of myeloid lineages. The subsequent development of mouse models carrying mutations found in patients proved that the aberrant activation of these specific pathways plays a crucial role in the pathology...

Alloimmunization is an immune response against red blood cell (RBC) antigens due to sensitization during RBC transfusion. RBC alloimmunization is more common in sickle cell disease (SCD) with prevalence between 18 and 47%. Retrospective chart review of a cohort of 120 children treated at Fundação Hemominas born between 1998 and 2007 and diagnosed with SCD through neonatal screening. The statistical analysis was made with the usage of Mann-Whitney’s U test, Student’s T-test and Chi-Square t...
Coping with Bleeding Disorders
Article Type: Case Report | First Published: October 14, 2020
Living with a bleeding disorder is something that very few live within the United States. In fact, hemophilia occurs in only approximately 1 in 5,000 live births. There are about 20,000 people with hemophilia A in the US. Hemophilia B is four times less common than hemophilia A. von Willebrand Disease is much more common than both hemophilia A & B which is believed to effect 1% of the population. Von Willebrand disease is estimated to affect 1 in 100 to 10,000 individuals. The 3 common bleeding ...

Hundred subjects were involved for this study. The subjects were divided into 2 groups: 50 sickle cell anaemic subjects (20 males and 30 females) and 50 non-sickle cell subjects or control (23 males and 27 females). Sickle cell anaemic subjects were between the age ranges of 15-41 years while control subjects were between 17-31 years. Subjects were both Sickle Cell Anaemic Centre, Benin City, Edo State, Nigeria and volunteer students at the Department Medical Laboratory Science, Ambrose Ali Univ...
Laboratory Blood Coagulation in Sudanese with Falciparum Malaria: A Glance of Change Outcomes
Bashir Abdrhman Bashir and Mohamed Seed Ahmed
Article Type: Original Research | First Published: September 03, 2020
Malaria is a potentially life-threatening disease caused by infection of erythrocytes with one of five different types of protozoan parasites of genus plasmodia. Falciparum species is an aggressive type associated with multiple alterations in hemostasis. A cross-sectional descriptive study was undertaken to screen the effect of malaria infection on coagulation test results in adults with the falciparum malaria parasite. Forty- eight consecutive adults with falciparum malaria were studied along w...
Influence of ABO Blood Group on Fibrinogen Levels and Platelet Count in Apparently Healthy Nigerian Subjects

Article Type: Original Article | First Published: July 25, 2020
A close association has been shown to exist between ABO blood type and the risk of some diseases with non-O (A, B, or AB) individuals having an increased differential disposition to thrombotic disorders. The present study evaluated the fibrinogen levels and platelet count in subjects of different ABO blood groups with the view of ascertaining if disparity exists in the levels of fibrinogen and platelet count amongst the different ABO blood groups....
Hemopure, HBOC-201, for Life Threatening Anemia in a Jehovah’s Witness

Article Type: Case Report | First Published: June 04, 2020
There are over 1 million Jehovah’s Witnesses in the United States and nearly 8.5 million worldwide. Within the medical community, they are most notably known for their refusal of blood transfusions. Prior studies have shown that healthy euvolemic volunteers tolerate hemoglobin of 5 g/dL, although when faced with the stress of surgery their operative mortalities are over 30%. Herein we explore the use of Hemopure, HBOC-201, an investigational blood substitute, for a frail 72-year-old female Jeh...
