Blood donation practices, processing and utilisation of blood components in government tertiary hospitals in Nigeria: a multicentre cooperative study.

Background: Timely access to safe blood and blood components is still a challenge in Nigeria. This study aimed to determine blood donation practices, processing and utilization of blood components across government tertiary hospitals (THs) in Nigeria.

Methods: This was a descriptive cross-sectional study done in Nigeria in June-July 2020.

Plasminogen Activator Inhibitor 1 (PAI-1) and Haematologic Parameters in HIV- Positive Patients on Protease Inhibitor-Based HAART Regimen: A Case-Control Study.

Human immunodeficiency virus (HIV) infection is associated with an increased risk of hypercoagulability and treatment with antiretroviral agents especially protease inhibitors has also been reported to contribute to this risk. Altered fibrinolytic activity is reported as a mechanism of increased thrombotic risk in HIV patients on therapy. However, this has not been investigated in our environment.

Prevalence of venous thromboembolism and its associations in a large racially homogenous population of sickle cell disease patients.

Unlabelled: To determine the prevalence of venous thromboembolism (VTE) among adult sickle cell disease (SCD) patients in Nigeria.

Methods: This was a multicentre retrospective study in which the medical records of adult SCD patients were reviewed. Information on demographics, steady-state haemogram, clinical phenotypes, duration of follow-up, history of VTE including risk factors and management was collected.

Determination of von Willebrand factor level in patient with sickle cell diseasein vaso-occlusive crisis.

Background: Sickle cell anemia (SCA) is a hypercoagulable state characterized by a significant alteration in hemostatic parameters that may predispose to increased risk of vaso-occlusive crisis (VOC). The role of von Willebrand factor (VWF) in the pathogenesis of VOC has not been fully investigated in Nigeria.

Objective: The objective of this study was to evaluate the level of VWF in subjects with sickle cell disease (SCD) in Calabar, Nigeria, to determine its role in the pathogenesis of VOC.

Health Status of Persons with Hemophilia: A Pilot Survey from a Resource-Constrained Country.

Background: Most resource-poor countries are yet to develop standard hemophilia treatment center (HTC) despite improved outcome of health status of persons with hemophilia (PWH).

Aim: This study aimed to evaluate the health status of PWH in Nigeria.

Methodology: In this descriptive, cross-sectional study, modified prevalidated and pretested questionnaire (National health and Nutrition examination survey (NHANES) 2013 Health Status questionnaire (HSQ)) was consecutively administered to consenting PWH (pediatric and adult) attending the 2018 Annual General Meeting of the Haemophilia Foundation of Nigeria.
