Refractory generalized edema : An infrequent complication of long-term pergolide treatment for Parkinson disease

2005 
Generalized edema is the result of increased interstitial fluid volume due to altered Starling forces or capillary endothelial damage. The authors present a patient with severe Parkinson disease who presented with increasing dyspnea, bilateral pleural effusion, and peripheral edema that was refractory to diuretics. Common causes of the severe loss of fluid into the extravascular space were ruled out and pergolide was suspected. Upon discontinuation ofpergolide therapy, all signs of fluid retention resolved. This report emphasizes that pergolide should be considered a cause of otherwise unexplained generalized edema in patients with Parkinson disease on this therapy.
