Long-term outcome of lung transplantation in previous intravenous drug users with talc lung granulomatosis.

Talc lung granulomatosis results from the intravenous use of medication intended for oral use. Talc (magnesium silicate) acts as filler in some oral medications; when injected intravenously, it deposits in the lungs leading to airflow obstruction and impaired gas exchange. Allocation of donor lungs to previous intravenous drug users is controversial. After a careful selection process, 19 patients with talc lung granulomatosis have received lung allografts in our program. Long-term survival for these patients is excellent and our results suggest the previous use of intravenous drugs should not necessarily preclude lung transplantation.
