Common renal findings at high altitude

Serum Findings
Polycythemia (excessive erythrocytosis)
Hemodynamic findings
    elevated systemic BP
    elevated renal vascular resistance
    elevated pulmonary artery pressure
Reduced renal plasma flow
    preserved GFR (elevated FF)
Renal pathology findings
Urinary findings
  • We suggest the designation high altitude renal syndrome to characterize the combination of polycythemia, systemic hypertension, hyperuricemia, and microalbuminuria.
