MedicalResearch.com Interview with: Lac Tran, MD Division of Nephrology and Hypertension Kaiser Permanente Los Angeles Medical Center Los Angeles, CA Medical Research: What is the background for this study? What are the main findings? Dr. Tran: Abnormal serum phosphorus levels have been associated with adverse cardiovascular outcomes and progression to renal failure.  Given phosphorus’s important biological roles in cellular replication and bone mineral metabolism, we sought to investigate the association between phosphorus levels and anemia in normal kidney function and early chronic kidney disease. Our study is a population-based study among a large racially/ethnically diverse population within the Kaiser Permanente Southern California health system. Among 155, 974 individuals, 4.1% had moderate anemia and 12.9% had mild anemia.  We found that phosphorus levels greater than 3.5 mg/dL and less than 2.0 mg/dL showed a greater likelihood for moderate anemia.  Every 0.5 mg/dL phosphorus level increase demonstrated a 16% greater likelihood for moderate anemia.  The highest phosphorus tertile of our population had a 26% greater likelihood for anemia compared to the middle tertile.  We also found that female sex, Asian race, diabetes, low albumin, and low iron saturation were risk factors for anemia.
