Surfactant Protein A Serum Level in Cement Worker

Background: Pneumoconiosis occurs almost in entire worldwide. had threatened cement workers. Serologic abnormalities found pneumoconiosis. Surfactant Protein A (SP-A) levels increased silica-exposed may be a helpful biomarker for the early diagnosis of pneumoconiosis, but it has not yet been studied Indonesia.Methods: The design this study was observational with cross-sectional. sampling cement-exposed workers done by consecutive sampling. subjects were 88, approach population 67 exposed from September 2017 – March 2018 and 17 healthy people as control. serum level SP-A measured ELISA method. Cement is worker production area quarry area.Results: total number research met criteria 67, control 21. mean subject group or 6.02 ng/ml, 4.50 ng/ml. difference between groups different significant, value P=0.084.Conclusion: statistically significant.
