Extracorporeal treatments have been used since the 1970s in the management of systemic lupus erythematosus (SLE). A randomised controlled trial comparing the efficacy of standard of care (SOC) combined with plasma exchange against SOC alone in patients with lupus nephritis revealed no difference in terms of renal outcome. Subsequently, initial expectations have been dampened and further experie...

Over the past 37 year the role of plasma exchange in the treatment of patients with renal disease has undergone several changes. The majority of the changes for the use of plasma exchange relied on randomized control trials and delineations of mechanisms that potentially would benefit from the use of plasma exchange. Over the past 11 years plasma exchange indications for renal disease, the abso...

OBJECTIVES The aim of this report is to evaluate the plasma exchange as a choice for the management of life-threating gastrointestinal system (GIS) involvement in Henoch-Schönlein purpura (HSP) when refractory to conventional therapies. METHODS We retrospectively reviewed the medical records of HSP patients who had plasma exchange therapy due to massive GIS involvement. We reported age, gende...

The results of plasma-ammonium determinations by an ion-exchange method and by a microdiffusion method were compared on the same specimens with each other and with ammonium determinations carried out on the corresponding whole-blood specimens by the microdiffusion method. The plasma-ammonium levels of whole-blood specimens were higher than those of the corresponding plasma specimens, but the di...

The outcomes of the treatment of thrombotic thrombocytopenic purpura (TTP) have been shown to be improved by the administration of plasma exchange. However, treatment options are currently limited for cases refractory to plasma exchange. The autoantibodies that block the activity of ADAMTS13 have been demonstrated to play a role in the pathogenesis of TTP; therefore, high-dose immunoglobulin, w...
