Silicosis Associated Osteoporosis

Silicate Associated Osteoporosis

We are investigating a recently identified disease in horses in which the bones become weak and osteoporotic. Research is focused on 1) determining what happens to affected horses; 2) evaluating diagnostic tests for early disease detection; and 3) identifying the underlying cause of the disease, risk factors for disease development, and management and prevention strategies.  Because many of the horses with the bone disease also have a lung disease called pulmonary silicosis, we are pursuing understanding of the link between the lung disease and the bone disease.
