title: Serum and effluent lysozyme (muramidase) activity in CAPD patients.
abstract: The elevated serum lysozyme activity in 13 chronic renal failure patients (n = 26) dropped significantly during their first three months of CAPD and subsequently returned to initial levels. When compared with peritoneal mass transfer of lysozyme and serum creatinine levels, a distinct correlation was observed between these and the fluctuations in serum lysozyme activity recorded up to three years of CAPD (r = 0.319, P less than 0.05 and r = 0.425, P less than 0.025, respectively). A notable drop in the mass transfer of this low molecular weight protein took place after the first hour of dialysis. We concluded that long-term CAPD does not affect serum lysozyme activity and that passive loss across the peritoneal membrane could account for the lysozyme found in the effluent fluid.
