Correlation between cytokine levels and liver function damage in patients with occupational medicamentosa-like dermatitis due to trichloroethylene / 中国职业医学

ABSTRACT

OBJECTIVE: To investigate the correlation between plasma cytokine levels and liver functions in patients with occupational medicamentosa-like dermatitis due to trichloroethylene(OMDT). METHODS: A total of 22 OMDT patients were selected as research subjects using judgment sampling method. Blood samples were collected from patients on the 1 st, 2 nd, 3 rd, 4 th, and 5 th week of admission and the day of hospital discharge. The automatic biochemical instrument was used for detecting the index of serum liver function. The levels of cytokines including tumor necrosis factor-α(TNF-α), interferon-γ(IFN-γ), interleukin(IL)-5, IL-6, and IL-10 in plasma were measured by enzyme-linked immunosorbent assay. The Spearman correlation analysis was performed to analyze the correlation between cytokines and liver function in 15 patients with exfoliative dermatitis. RESULTS: The levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bilirubin(TBIL), direct bilirubin(DBIL), glutamyl transpeptidase(GGT), and total bile acid(TBA) of OMDT patients on the 1 st week of admission increased(P<0.05), while total protein(TP) and albumin(ALB) decreased(P<0.05) compared with the results at discharge(a stage of recovery). The correlation analysis results of patients with exfoliative dermatitis showed that the levels of TNF-α, IFN-γ and IL-6 were negatively correlated with the levels of TP and ALB respectively(P<0.05), the level of IL-5 was negatively correlated with TBIL(P<0.05), and the level of IL-10 was negatively correlated with ALB(P<0.05) in the 1 st week. The level of IL-6 was positively correlated with ALT(P<0.05) in the 2 nd week. The level of TNF-α was positively correlated with TBIL(P<0.05), the level of IL-10 was positively correlated with AST(P<0.05) in the 3 rd week. The levels of TNF-α and IL-10 were positively correlated with AST and ALT respectively(P<0.05), the level of IFN-γ was positively correlated with AST(P<0.05) in the 4 th week. The levels of IL-6 and IL-10 were positively correlated with ALT and GGT(P<0.05), and the levels of TNF-α and IFN-γ were positively correlated with AST(P<0.05) in the 5 th week. The level of TNF-α was negatively correlated with DBIL(P<0.05) and was positively correlated with TBA(P<0.05) at discharge.CONCLUSION:s Patients with OMDT are frequently accompanied with severe liver function damage at the early stage. The level of plasma cytokines(TNF-α, IFN-γ, IL-6 and IL-10) might correlate with the severity of liver dysfunction.
