Analysis of inflammatory markers in apparently healthy automobile vehicle drivers in response to exposure to traffic pollution fumes

Abstract

Objective: This study aimed to evaluate pattern of markers of inflammation in apparently healthy drivers who exposed to traffic fumes.
 Methods: This cross-sectional study was conducted from June 2016 to January 2017 at Liaquat University of Medical & Health Sciences (LUMHS), Jamshoro. It looked into the effects of traffic pollutants on markers of inflammation including CRP, Leukocytes count, IL-6, TNF-α, TNF-β of healthy human volunteers. Eighty-seven, apparently healthy, non-smoking automobile vehicle drivers, having daily contact of traffic exhaust for at least six hours, aged between 18-40 years recruited for this study. Levels of traffic-generated pollutants P.M2.5, P.M10, NOx were recorded in different areas of Hyderabad City.
 Results: P.M2.5 found to be positively correlated with markers of inflammation including IL-6 (rs = 0.99), TNF-α (rs = 0.41), CRP mg/dl (rs = 0.99) , neutrophils (rs = 0.29), lymphocytes (rs = 0.31), eosinophils (rs = 0.20), monocytes (rs = 0.42) and basophils (rs = 0.16). Positive correlation present among IL-6 (rs = 0.21), TNF-α (rs = 0.49) and CRP mg/dl (rs = 0.22) (rs = -0.31), Leukocytes (rs = 0.14) neutrophils (rs = 0.31), lymphocytes (rs = 0.21), monocytes (rs = 0.50), basophils (rs = 0.17) with P.M10. NOx showed positive correlation with IL-6 (rs = 0.22), TNF-α (rs = 0.48), CRP (rs = 0.22), neutrophils (rs = 0.31), lymphocytes (rs = 0.13), basophils (rs = 0.17) and monocytes (rs = 0.48).
 Conclusion: Findings of our study suggest that almost all markers of inflammation are positively correlated with traffic pollutants and this condition might raise the risk of systemic diseases.

Methylomic, proteomic, and metabolomic correlates of traffic-related air pollution: A systematic review, pathway analysis, and network analysis relating traffic-related air pollution to subclinical and clinical cardiorespiratory outcomes

“…Three of the methylomic markers (for genes CSF2, IL6, and IL10 ) were described in the section on inflammation and immunity. Briefly, short- and long-term TRAP was associated with hypomethylation of these markers and higher levels of the proteins they encode [58,73,88–91,113,115,124,141,162,205,225,235,254,255]. Hypermethylation of one methylomic marker relevant here (related to a gene that encodes interferon gamma ( IFNG )) was associated with short-term TRAP exposure (though short-term BC was associated with hypomethylation) [38,256].…”

“…Three of the methylomic markers (for the genes CSF2 , IL6 , and IL10 ) were described in the section on inflammation and immunity.

Hypermethylation of one methylomic marker relevant here (related to a gene that encodes interferon gamma ( IFNG )) was associated with short-term TRAP exposure (though short-term BC was associated with hypomethylation) [ 41 , 120 ].…”

Determination of serum tumor necrosis factor-alpha (TNF-α) levels in metabolic syndrome patients from Saudi population

“…Various studies have demonstrated that pro-inflammatory markers like TNF-α impart their roles in developing cardiovascular diseases, metabolic syndrome, obesity, type 2 diabetes, insulin resistance, and non-alcoholic fatty liver disease. 10 , 11 The current study was carried out to demonstrate the association between serum TNF-α and MetS characteristics.…”
