111 A LUPUS NEPHRITIS PATIENT WITH BREATHLESSNESS FOLLOWING PLASMA EXCHANGE

Abstract

Category: Other Presenter: Dr WAN HASNUL HALIMI WAN HASSAN Keywords: SLE, lupus nephritis, plasma exchange, fluid overload A 17 years old girl, diagnosed with Lupus nephritis since 2014. She had Lupus Nephritis class III , in partial remission following treatment with t.mycophenolate mofetil (MMF). She was transferred to high dependency ward requiring non invasive ventilation after 4th cycle of plasmapharesis. This is due to fluid overload and her condition improves after hemodialysis and ultrafiltration. She initially presented with symptoms of facial puffiness and leg swelling for 2 weeks. She was admitted was started on high dose prednisolone (60mg OD) and t.MMF 1g BD. Progressive worsening renal function was noted (urea 29/creat 190; baseline renal function was normal urea/creat) Renal biopsy results shows Crescentric Lupus Nephritis, ISN/RPS class IV-G (A/C). activity index 15/24, chronicity index 4/12. (57% cellular crescent, 15% global sclerosis). IV cyclophosphamide induction and plasma exchange was initiated. She completed total of 10 plasmapheresis cycle and is currently still ongoing 3rd cyclophosphamide induction. Her renal profile shows improvement (urea 15.7/creatinine 116). Plasma Exchange is a recognized modality of treatment in more severe and/or resistant lupus nephritis, moreover for crescentic glomerulonephritis. The complication rate of is not high. The Swedish registry reported no fatalities during 20,485 procedures, and an overall adverse incidence rate of only 4.3% of all exchanges (0.9% for severe adverse events) of which 27% were paresthesias, 19% transient hypotension, 13% urticaria, and 8% nausea. An overall complication rate of 1.4% has been reported in more than 15,000 treatments in patients receiving albumin, and 20% in patients receiving FFP. There's increases the risk of bleeding as a result of depletion of coagulation factors in patients receiving albumin as sole replacement colloid. A study in Japan looking at 53 kidney transplant recipients receiving plasma exchange for desensitization, recorded the were no severe adverse event, milder events were pruritus 53%, numbness 40% and mild dyspnea 5%. The incidence of numbness during plasma exchange was less in patients receiving combined hemodialysis. In our case, fluid overload was noted as a major complication requiring non invasive ventilation and hemodialysis. This is due to the large volume exchange and associated renal impairment. Although uncommon, fluid overload and other complication related to large volume plasma exchange is needed to be taken under account in a renal impaired patient.
