We are conducting a research study on the effect of high insulin levels on the buildup of excessive liver fat ("fatty liver disease") in people at risk for type 2 diabetes. We are seeking adult volunteers, ages 18-65, who have obesity with a body mass index of 30-45, and have been diagnosed with, or are at risk for, prediabetes and metabolic…
We are studying the natural course of autoimmune hemolytic anemia (AIHA). If you are an adult between 18 and 120 years old, receive care at Columbia University Irving Medical Center-New York Presbyterian Hospital, are willing to provide a blood sample every 6 months for research, and have one of the following diagnoses: AIHA, mixed AIHA, Evans Syndrome, or…
The purpose of this study is to develop a cohort of patients with early scleroderma and to collect data on clinical outcomes, radiological tests, laboratory tests, and to obtain biological specimens for testing.
We are conducting a research study on how insulin controls blood sugar in both healthy people and those at risk of type 2 diabetes. We are seeking adult volunteers, aged 18-65, who have body mass indices either in the lean range (18-25 kg/m2) or in the obesity range (30-45 kg/m2) but who do not have prediabetes or diabetes. Participants will undergo a…
This research is being done to determine how variations in genes may explain the different risk to develop scleroderma (or CREST) seen in African American patients compared to other populations. People who are African American with scleroderma (or CREST) may join. This research involves a blood draw and physical exams.
