Hypothesis

Does mild to moderate long-term exposure to vinyl chloride monomer affect liver enzyme levels in workers?

Conclusion

Mild exposure to vinyl chloride can cause mild liver cholestasis, indicating the need for regular liver function assessments in affected workers.

Supporting Evidence

  • Liver enzyme levels were significantly higher in workers exposed to vinyl chloride compared to controls.
  • The study found a statistically significant relationship between VCM exposure and increased ALP and GGT levels.
  • No significant differences were found for other liver enzymes between the two groups.

Takeaway

Workers exposed to vinyl chloride might have slight liver problems, so it's important to check their liver health regularly.

Methodology

Cross-sectional study comparing liver enzyme levels of 52 workers exposed to vinyl chloride with 48 control workers using T-tests.

Potential Biases

Potential confounding factors such as BMI, smoking, and alcohol consumption were not systematically controlled in previous studies.

Limitations

The study did not measure bile acid levels or perform hepatic and splenic sonography due to financial constraints.

Participant Demographics

All participants were Iranian males with at least 2 years of work experience.
