Abstract: Five hemodialysis patients were treated with combined hemodialysis-hemoperfusion with their conventional hemodialyzer plus a 70-gram ultrathin collodion coated activated charcoal device for a total of 63 months. Indications for this therapy included pericarditis, peripheral neuropathy, clotting of conventional hemodialyzers and reduction of dialysis time and frequency. The outcome was beneficial in all cases and stable biochemical and hematological parameters were maintained. No increase in heparin requirements was noted and the therapy was thought to be cost-effective.
Which is the apt title for the abstract? option1: Routine clinical applications of hemodialysis-hemoperfusion in chronic renal failure: case reports. option2: Adrenal insufficiency due to cryptococcosis.
Output:
Routine clinical applications of hemodialysis-hemoperfusion in chronic renal failure: case reports.
