Clinical Expertise

Dr. Gladwin's clinical research and expertise focuses on pulmonary hypertension and pulmonary complications of sickle cell disease. He was the PI on the multi-center clinical trials Walk-PHASST (Pulmonary Hypertension and Sickle Sildenafil Therapy Trial) and DeNOVO (Delivery of NO for Vaso-Occlusive pain crisis in sickle cell disease). He has served as a principal or associate investigator on more than 25 human subjects protocols and holds seven FDA INDs for the use of investigational therapeutic medications, including nitrite, carbon monoxide, L-NMMA, and sildenafil.

Research Interests

Dr. Gladwin's research activities have led to four major discoveries:
  1. The discovery that the nitrite anion is a circulating storage pool for NO bioactivity (Gladwin, et al. PNAS 2000) that regulates hypoxic vasodilation (Cosby Nature Medicine 2003) and the cellular resilience to low oxygen and ischemia (Duranski JCI 2005).
  2. The discovery of a novel physiological function for hemoglobin as an electronically and allosterically-regulated nitrite reductase (Cosby, et al. Nature Medicine 2003; Huang et al. JCI 2005).
  3. The characterization of a novel mechanism of disease, hemolysis-associated endothelial dysfunction (Reiter, et al. Nature Medicine 2002; Morris et al. JAMA 2005; Minneci et al. JCI 2005; Rother et al. JAMA 2005).
  4. The mechanistic, clinical, and epidemiological description of a human disease syndrome, hemolysis-associated pulmonary hypertension (Gladwin, et al. NEJM 2004).
