HemMa Study

HemMa is a prospective cross-sectional observational study that aims to identify hematological markers in patients with sickle cell disease. The study is a collaboration between the Biologics Research Center of CSL Behring at SITEM and the Department of Hematology of the University Hospital (Inselspital) Bern. CTU Bern is involved in designing, implementing, conducting, and analyzing the study.

The HemMa study investigates a very rare and serious illness named “sickle cell disease”. The disease causes red blood cells to break down and can affect nearly every organ in the human body. Patients suffer from a poor quality of life and a reduced life expectancy.

The study collects blood and urine samples in patients with sickle cell disease and a matched control group. The primary aim is to identify potentially novel biomarkers to more precisely characterize the pathophysiological mechanisms involved in the disease complications.
