Assessment of Some Haematological, Coagulation and Immune Parameters among Male Oil Refinery Workers in Port Harcourt, Nigeria
Aim: The aim of this study was to assess the levels of some hematological, coagulation and immune parameters among male oil refinery workers in Port Harcourt, Nigeria.
Study Design: This study is a cross-sectional study.
Place and Duration of Study: Rivers State University Teaching Hospital (RSUTH), Port Harcourt, Shell Petroleum Development Company of Nigeria Limited and Modular Oil Refinery, Rivers State, between January 2021 and September 2021.
Methodology: A total of one hundred (100) subjects (50 oil and gas workers as test subjects and 50 non-oil and gas workers as control subjects), were enrolled in the study. The convenient sampling technique was employed in the study. Venous blood samples were collected from all subjects and tested for Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT), Fibrinogen concentration, Full Blood Count (FBC) (Haemoglobin (Hb), Packed Cell Volume (PCV), Total White Blood Cell (WBC) count, Lymphocyte, Neutrophils, monocytes and Platelet Count), CD4 cell count, CD3 cell count and CD8 cell count. Data generated were analyzed statistically using Graph-Pad Prism, Version 8.0.2.
Results: There was statistically significant decrease (P<.001) in Prothrombin time (PT) (11.55±0.73s), International Normalized Ratio (INR) (0.85±0.05), Fibrinogen (202.4±27.4mg/dl), Platelet count (185.6±37.1(103/μl)) and Neutrophils (46.6±6.4%) in oil refinery workers exposed to gas flare, while there was a statistical significant increase in APTT (31.8±4.15s), Hb (13.7±1.0g/dl), PCV (41.1±3.2%), Monocytes (8.4±3.0%) in subjects exposed to gas flare over control subjects with Prothrombin time(12.23±0.82s), INR(0.90±0.06), Fibrinogen(252.0±57.0mg/dl), platelet count(213.3±49.5(103/μl)) and Neutrophils(52.6±11.7%). Other parameters showed no statistical significant difference at P<.05 in both test and control subjects. Comparison of the mean ± standard deviation of the studied parameters in test subjects based on age using Analysis of Variance showed no statistically significant difference in all parameters at P<.05. Also, Comparison of the mean ± standard deviation of the studied parameters in test subjects based on duration of Exposure using Analysis of Variance showed a significant decrease in CD8 cells as the years of exposure increase (2-5years exposure = 865±319, 6-10years exposure = 579±288, 11-20 years exposure = 591± 286, F- Value = 3.869, P- Value = 0.0278).
Conclusion: In conclusion, based on the findings, some haematogical, coagulation and immune parameters increased while others decreased in male oil refinery workers and duration of exposure can also be considered as a risk factor and age was considered not a risk factor as to cause any aberrations in the studied parameters.
