Background Hypofibrinolysis resulting from the up-regulation of plasminogen activator inhibitor-1 (PAI-1) usually occurs in patients with type 2 diabetes mellitus (T2DM), rendering them hypercoagulable. This study assessed the plasma antigen and activity levels of the PAI-1 enzyme in T2DM patients in a district hospital in Ghana. Methods This was a hospital-based case-control study conducted from December 2018 to May 2019 at Nkenkaasu District Hospital. Sixty subjects with T2DM (30 T2DM subjects with good glycemic control and 30 with poor glycemic control), and 30 apparently healthy blood donors were recruited into the study. Blood specimens were collected for complete blood count, lipid profile, PAI-1 Ag and PAI-1 activity levels. A pre-tested questionnaire was used to obtain demographic and clinical information. The data was analyzed using SPSS version 22.0. Results Elevated PAI-1 Ag and activity levels were observed in the T2DM subjects compared to the healthy controls, with the levels and activity significantly higher (PAI-1 Ag; p< 0.001, PAI-1 activity level; p = 0.004) in the T2DM subjects with poor glycemic control in comparison to those with good glycemic control. A significant positive correlation was observed between HbA1c and PAI-1 enzymes. PAI-1 Ag levels significantly increased along with increased total cholesterol (Β = 0.262, p = 0.033), triglyceride (Β = -0.273, p = 0.034) and HbA1c (Β = 0.419, p = 0.001). Similarly, PAI-1 activity level was associated with total cholesterol (Β = 0.325, p = 0.009), triglyceride (Β = -0.262, p = 0.042), HbA1c (Β = 0.389, p = 0.003) and VLDL-c (Β = -0.227, p = 0.029). Conclusion PAI-1 antigen/activity is enhanced in poorly controlled Ghanaian T2DM subjects. The hypercoagulable state of the affected individuals put them at higher risk of developing cardiovascular diseases. Good glycemic control to regulate plasma PAI-1 levels is essential during T2DM lifelong management. Markers of fibrinolysis should be assessed in these individuals and appropriate anticoagulants given to prevent thrombosis and adverse cardiovascular diseases.

Background and Aim: Impaired coagulation and fibrinolysis have been implicated in thromboembolism in human immunodeficiency virus (HIV)-infected individuals. This study evaluated the plasma levels of plasminogen activator inhibitor-1 (PAI-1) and coagulation biomarkers in HIV-infected individuals on highly active antiretroviral therapy (HAART).Methods: This matched case-control study from March to December, 2020 comprised 76 participants: 38 HIV-positive individuals on HAART and 38 apparently healthy HIV-negative individuals as controls. Blood samples were collected for prothrombin time (PT), activated partial thromboplastin time (aPTT), D-dimers, PAI-1, and soluble fibrin monomer complex (SFMC) estimations. The data were analysed using SPSS version 22.0 and statistical significance was set at p < 0.05.

Introduction: The burden of hernia is disproportionately high in low-to-middle-income countries, due to the lack of fundamental resources needed to effectively diagnose and manage cases. The patterns of hernia, the haematological profile, and the predictive ability of blood cell indices were all investigated in this study. Methods: Fifty-four subjects: 27 hernia patients and 27 healthy controls were included in this single-centre, unmatched case-control study. Hernia was diagnosed using physical examination and ultrasound scan. Haematological indices of each subject were measured with an automated blood cell counter. Results: Herniae recorded were 92.59% inguinal, and 3.27% each epigastric and uterine prolapse. Hernia was prevalent in males (85.2%, p=0.008) and older subjects ≥53 years (48.1%, p=0.004). HgB (p=0.006), MCHC (p≤0.001), and RDW-CV (p=0.042) levels were significantly elevated in strangulated than non-strangulated hernia and controls respectively, while Abs GRAN (p=0.024) was decreased in non-strangulated than strangulated hernia and control groups respectively. MCHC (AUC=0.947 [0.895-0.999], p≤0.001) was the most sensitive predictor for herniation followed by age (AUC=0.750 [0.610-0.889], p=0.002); HgB (AUC=0.718 [0.580-0.857], p=0.006); and RDW-CV (AUC=0.700 [0.559-0.840], p=0.012). Also, MCHC (AUC=0.831 [0.723-0.938], p≤0.001); HgB (AUC=0.738 [0.590-0.887], p=0.005); and RBC (AUC=0.671 [0.502-0.840], p=0.045) respectively, were significant predictors of strangulation. Conclusion: Gender and age were significantly associated with hernias. Inguinal hernia and strangulation were common in the study setting, especially, among males. Also, there were significant variations in erythrocyte- and leucocyte indices across the groups, but not platelets. Erythrocyte indices were significant predictive biomarkers for hernia and strangulation. The CBC is a useful test for the early detection of herniation and strangulation. Doi: 10.28991/SciMedJ-2022-0401-1 Full Text: PDF

Background: The ABO blood antigens may influence the levels of vWF: Ag and put individuals at risk of coagulopathies. This study assessed the plasma vWF: Ag and its relation with ABO blood antigens among healthy adults in northern Ghana. Methods: This cross-sectional study recruited 84 blood donors, aged 18–50 years, at Tamale Teaching Hospital. Blood groups were determined using the standard tube method, and a complete blood count was measured with an automated haematology analyzer. Sandwich ELISA was used to assess plasma vWF: Ag levels. The data obtained were analyzed using SPSS version 22. Results: The frequencies of O, A, B, and AB blood groups were 34 (40.5%), 25 (29.8%), 20 (23.8%), and 5 (6.0%), respectively. vWF: Ag levels were higher among the non-O than group O individuals (p = 0.008). Plasma vWF: Ag levels were lower in group O compared to AB (p = 0.015) and A (p = 0.013) individuals. Males had higher vWF: Ag levels than females (p = 0.002). A moderately positive correlation was observed between age and vWF levels (r = 0.497, p<0.001). Blood group O participants had lower absolute neutrophil counts (p = 0.039), but higher RDW-SD (p = 0.045). Conclusion: The predominant blood group was O, followed by other groups in the order: O>A>B>AB. Plasma vWF: Ag levels were higher in non-group O compared with group O individuals. Males had higher vWF: Ag levels, and a positive correlation between age and vWF: Ag was observed. Again, blood group O participants had lower neutrophil counts, but higher RDW-SD. The relationship between ABO blood phenotypes and plasma vWF: Ag should be considered in clinical practice. The establishment of separate reference intervals of vWF: Ag for the various phenotypes of ABO is recommended. Also, the study recommends further multicenter studies to assess the link between ABO phenotypes and all the endothelial cell parameters. Doi: 10.28991/SciMedJ-2022-04-02-02 Full Text: PDF
