Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Viamin D levels in kidney dialysis patients

    Researchers from Canada and the US looked for factors that might predict patients with kidney failure who are vitamin D deficient.

    First, the details.

    • 908 patients with known 25-hydroxyvitamin D levels were studied.
    • Factors that might predict the presence of a vitamin D deficiency were evaluated.

    And, the results.

    • 79% of the patients were vitamin D deficient (25-hydroxyvitamin D less than 30 ng/mL).
    • Strongest predictors of vitamin D deficiency
      • Black race
      • Female sex
      • Winter season
      • Low albumin blood levels (hypoalbuminemia; blood albumin at least 3.1 g/dL)
    • The presence of hypoalbuminemia along with dialysis started during the winter was associated with 100% vitamin D deficiency in black women and black men.
      • In white women and men vitamin D deficiency was 94% and 92%, respectively.

    The bottom line?

    The authors concluded, “Deficiency of 25-hydroxyvitamin D is nearly universal among patients with hypoalbuminemia initiating chronic hemodialysis in winter.”

    It’s not proven, say the authors, that correcting these factors will benefit these patients clinically.
