ABSTRACT
Chronic systemic inflammation is a pathophysiological feature of sickle cell disease (SCD). Considering that regular exercise exerts multiple beneficial health effects including anti-inflammatory actions, we investigated whether a treadmill training program could minimize the inflammatory state in transgenic sickle cell (SS) mice. To test this hypothesis, SS mice were subjected to a treadmill training protocol of 1h/day, 5days a week for 8weeks. Exercise training increased the percent of venous oxyhemoglobin and sharply decreased the percent of carboxyhemoglobin suggesting that exercise training may limit the proportion of erythrocytes that were deoxygenated in the venous circulation. Exercise training attenuated systemic inflammation as attested by a significant drop in white blood cell (WBC) count and plasma Th1/Th2 cytokine ratio. There was reduction in interleukin-1ß and endothelin-1 mRNA expression in trained sickle mice. The spleen/body mass ratio was significantly decreased in trained sickle mice and there was a strong correlation between the magnitude of congestion and the relative spleen mass in all animals (trained and untrained). We conclude that moderate intensity exercise training, without any noticeable complications, may be associated with limited baseline blood deoxygenation and inflammation in sickle cell mice, and reduce sequestration of sickle erythrocytes/congestion in the spleen.
