Plasma-immunoreactive trypsin in chronic renal failure

H Koop, K W Rumpf, P G Lankisch

    Summary

    Plasma immunoreactive trypsin (IRT) levels are elevated in patients with chronic kidney disease, correlating with creatinine. Kidney function significantly impacts trypsin metabolism, potentially affecting pancreatitis diagnoses.

    Area of Science:

    • Nephrology
    • Clinical Biochemistry

    Background:

    • Plasma immunoreactive trypsin (IRT) is an enzyme relevant to pancreatic function.
    • Chronic renal failure (CRF) affects various metabolic processes.
    • Accurate diagnosis of pancreatitis is crucial in patients with kidney disease.

    Purpose of the Study:

    • To investigate the relationship between plasma IRT levels and chronic renal failure.
    • To determine the influence of renal replacement therapies on plasma IRT.

    Main Methods:

    • Radioimmunoassay was used to measure plasma IRT in 52 patients with CRF.
    • Patients were categorized into conservative treatment, hemodialysis, and hemofiltration groups.
    • Correlation analysis was performed between plasma IRT and plasma creatinine.

    Main Results:

    • Plasma IRT levels were elevated in patients with CRF, showing a significant positive correlation with plasma creatinine (r = 0.853; p < 0.001).
    • Hemodialysis and hemofiltration did not significantly alter plasma IRT levels.
    • The kidney plays a crucial role in the metabolism of plasma trypsin.

    Conclusions:

    • Elevated plasma IRT in CRF suggests impaired renal clearance of trypsin.
    • IRT measurements for diagnosing pancreatitis may be unreliable in patients with kidney disease.
    • Renal function is a key factor to consider when interpreting plasma IRT levels.
