Under this study, we would like to collect specimens from CP patients who will undergo pancreatic resection at the VA Hospital for in vitro experiments. In these experiments, we will determine whether immune cells from CP patients are different from cells from healthy donors purchased from ATCC or other commercial sources. We will then assess whether pre-culture of immune cells from CP patients with MSCs can shift them to less pro-inflammatory phenotypes that won't induce inflammation in neuronal cells. All studies will be done in vitro in the cell culture system. Exploring mechanisms that contribute to chronic pain is vital for veterans' health and VA healthcare.

The purpose of this study is to test to see if you have a certain genetic mutation (changes in DNA) so we can learn more about kidney disease. The study involves one blood and saliva test and takes about 30 minutes. The blood test is to see if you have genetic changes in your DNA of a protein called APOL1. People who have this gene mutation may be at risk of losing their kidney function faster than others. The test won't cost you anything. In fact, if you decide to participate, you will be compensated $45. You should know that the test used to determine if you have an APOL1 genetic mutation is not FDA approved, however the FDA has approved this test for research purposes. If you were to participate in this study and take the blood test, and the result indicated you have this mutation, there may be an opportunity in the future to volunteer in an additional research study where you will receive the treatment. This treatment is designed by Vertex, especially for people with kidney disease from APOL1 mutation.
