Abstract:

Pneumoconiosis is one of the most important and serious occupational diseases in China. In recent years, the number of notified pulmonary tuberculosis (PTB) ranks as the second place in the class A and B infectious diseases after viral hepatitis. PTB is a common complication among pneumoconiosis patients and is caused by a combination of various factors. This article introduced the incidence of PTB in patients with pneumoconiosis in recent years in different areas of China, and analyzed the researches on the susceptible factors for developing PTB. It is concluded that the incidence of PTB is still high in patients with pneumoconiosis. The results showed that the possible susceptible factors included: the stage of pneumoconiosis, age of onset, the years exposure to dust, type of work, the age of exposure to dust and other occupational susceptible factors, as well as other susceptible factors such as gene and preventive medication. In recent years, the related researches more aimed at the diagnosis and treatment of pneumoconiosis tuberculosis, but less on the cause of the disease and how to prevent and control the disease. The existing researches have various shortcomings and differences, and need to be further verified. Through our study, we suggest that the regular physical examinations to the workers exposed to dust and the patients with pneumoconiosis should be strengthened to timely detect the patients with pneumoconiosis and the pneumoconiosis patients complicated with PTB. Populations with the susceptible factors for developing PTB, such as the pneumoconiosis patients at higher pneumoconiosis stage, workers with longer time exposure to dust or earlier age exposure to dust and engaging in excavation work, etc., should be regarded as the key populations of prevention and give special attentions. So the incidence of pulmonary tuberculosis in patients with pneumoconiosis can be reduced and the pneumoconiosis tuberculosis can be effectively controlled.
