Summary
The prevalence of High Altitude Polycythemia (or Chronic Mountain Sickness) is between 8 and 15% in the high altitude regions of South America. There is no pharmacological treatment available. After a first preliminary study in 2003 demonstrating the beneficial effects of acetazolamide in reducing hematocrit in these patients, after 3 weeks of treatment, we want to confirm this effect and implement a treatment protocol of 3 month-duration.
