The Impact of Internal Medicine Research
Since 2010, department researchers have received funding totaling more than $67 million from the National Institutes of Health (NIH), leading to discoveries and inventions that have had a profound nationwide impact.
Vaccine researchers' substantial contributions have helped save lives and protect the public from viruses such as influenza, herpes and Zika. Researchers have also played a role in the national response to terrorism by rapidly testing potential smallpox vaccines.
Nephrology researchers are leading the nation's efforts to increase the annual number of kidney transplants, including the safe use of kidneys from liver donors. Their research also includes secondary hyperparathyroidism in chronic renal failure and the function of SALL genes in kidney growth.
Geriatric medicine researchers are the nation's leading educators in healthy and vibrant aging. They've studied and developed novel approaches to manage delirium, frailty and Alzheimer's Disease.
Rheumatology researchers have helped develop treatments for lupus, a disabling and often deadly autoimmune disease that disproportionately affects women, particularly African Americans.
The Saint Louis University Liver Center is notable for its research on hepatitis C, with studies exploring how the virus attacks the liver and causes cirrhosis and liver cancer. Researchers have been at the forefront of efforts to study and treat chronic hepatitis C; work that has and will continue to help save hundreds of thousands of lives around the world.
