Abstract

Transient or intermittent plasmapheresis with concurrent immunosuppressive therapy is thought to be beneficial in the treatment of recurrent focal segmental glomerulosclerosis (FSGS) in the early post-transplant period. The results of long-term (6-year) plasmapheresis therapy, in a 9-year-old female with an immediate recurrence of FSGS [urinary protein/urinary creatinine (UP/UC)=17.7] after cadaveric renal transplant, are presented. A 4-week plasmapheresis course induced a decline in the proteinuria, but a relapse occurred after cessation of plasmapheresis. Addition of protein A column therapy led to a further decrease in the proteinuria, to a non-nephrotic range. Long-term control of the nephrotic syndrome was established using a chronic treatment regimen consisting of a single-volume plasmapheresis, followed by a protein A column treatment, performed on sequential days every 3-4 weeks. Mean UP/UC values decreased to 1.15±0.9. A course of cyclophosphamide was successfully used to control a worsening of proteinuria 4 years post transplant. Although sequential renal biopsies demonstrated progressive glomerular sclerosis, the patient's mean calculated creatinine clearance only modestly declined from 78.3 ml/min per 1.73 m2, at the time of transplantation, to 62.7 ml/min per 1.73 m2, 6 years later. This patient demonstrated dependence on plasmapheresis/protein A column therapy to maintain a clinical remission of her FSGS recurrence. While long-term plasmapheresis and protein A column therapy in combination with immunosuppressive therapy reversed the effects of uncontrolled nephrosis and possibly facilitated long-term renal allograft survival, the glomerular sclerosis continued to progress.
