    Elevated prolactin levels are common in patients with kidney disease, often linked to impaired renal function rather than medication. Successful kidney transplants can normalize these prolactin concentrations, highlighting the kidney's role in prolactin metabolism.

    Area of Science:

    • Nephrology
    • Endocrinology
    • Biochemistry

    Background:

    • Hyperprolactinemia is frequently observed in patients with chronic kidney disease.
    • The precise causes and mechanisms underlying elevated prolactin in renal impairment are not fully understood.
    • Distinguishing between drug-induced and kidney-related hyperprolactinemia is clinically important.

    Purpose of the Study:

    • To investigate the prevalence and causes of elevated prolactin concentrations in patients with renal disease.
    • To explore the relationship between prolactin levels, renal function, and kidney transplantation.
    • To determine the kidney's role in prolactin metabolism.

    Main Methods:

    • Comparison of basal prolactin concentrations in 357 renal disease patients and 210 controls.

  • Analysis of prolactin levels in relation to drug therapy and renal function (creatinine).
  • Measurement of arteriovenous prolactin concentration differences across the kidney in select patients.

    • Main Results:

    • 32% of renal patients (113/357) had elevated prolactin; 53% of these were possibly drug-related.
    • In 60 patients without drug-induced hyperprolactinemia, elevated prolactin correlated significantly with impaired renal function (P < 0.005).
    • Prolactin levels normalized post-renal transplantation, and a significant arteriovenous prolactin difference across the kidney was observed.

    Conclusions:

    • Hyperprolactinemia in renal disease is partly due to impaired renal function, not solely drug effects.
    • The kidney plays a significant role in prolactin metabolism, evidenced by correlations with creatinine and normalization post-transplant.
    • Abnormal prolactin secretion regulation may contribute to hyperprolactinemia in renal failure.
