Research Summary

Dr. Lloyd Friedman recently published the results of a multicenter trial investigating the incidence of reversion of latent tuberculosis infection through the use of skin tests and interferon gamma release assays. He has been following a cohort of welfare patients in New York to assess the incidence of tuberculosis, AIDS, and death. His major focus currently is an experimental project on the association of a tuberculosis and asthma. His critical care efforts include participation as a study site principal investigator in a recently reported study on the use of drotrecogin alpha (activated) in early sepsis. He also has an interest in the improvement of medical care through the use of electronic medical records.
