Acute Guillain-Barré syndrome is the most common cause of neuromuscular paralysis. Plasma exchange and intravenous immune globulin (IV IgG) are both effective treatments for this condition and the purpose of this report was to compare the cost-effectiveness of these two modalities. A MEDLINE search was performed to identify randomized studies that compared the use of IV IgG and plasma exchange for treatment of acute Guillain-Barré syndrome to determine if one modality was more effective and/or safer for the management of this condition. ⋯ Plasma exchange and IV IgG are both effective treatments for Guillain-Barré syndrome. However, our analysis determined plasma exchange on average was almost $4,000 less costly per patient than IV IgG. Further research is required to determine the impact of patient and physician preferences on the treatment of this disorder.

Experience of double filtration plasmapheresis in the treatment of Guillain-Barré syndrome.
Therapeutic plasma exchange (TPE) is a standard treatment in Guillain-Barré syndrome. TPE may require exogenous fluid for replacement of plasma and, depending on the equipment used, varying extracorporeal volumes. Potential adverse effects include allergic reaction, infection, and hypotension. ⋯ Only two patients (12.5%) could not reach grade 2 at the end of 6 months. Our results were comparable to previously published results of TPE. We conclude that DFPP may be as effective as TPE in the treatment of GBS.

Intravascular stents do not cause microangiopathic hemolysis or thrombotic microangiopathy.
An increased incidence of TTP has been noted among patients receiving intravascular stents to improve patency in diseased coronary, renal, and peripheral arteries. Placement of transjugular intrahepatic porto-systemic shunt stents is often associated with subsequent development of severe hemolysis. We have prospectively studied the development of microangiopathic hemolysis or TTP in patients undergoing intravascular stent placement for peripheral vascular or renal artery disease. ⋯ No patient developed new renal impairment, a neurological syndrome, or unexplained fever after stent placement. At a mean of 6 weeks follow-up after stent placement, patients have not developed signs of hemolytic anemia or worsening renal function. Our findings argue against a primary risk of microangiopathic hemolytic anemia or TTP due to intravascular stents in patients not receiving ticlopidine.
