New study finds high rates of vitamin D deficiency in kidney transplant patients

Researchers have recently found that vitamin D deficiency is common in kidney transplant patients in Southern California.

These findings were presented at the National Kidney Foundation’s 2014 Spring Clinical Meeting. This meeting allows for kidney health care providers to come together and learn about and discuss the latest developments in various aspects of kidney health.

Vitamin D is important in any surgical procedure as higher vitamin D levels can help decrease the risk of inflammation and infection. Vitamin D deficiency may increase the risk of the patient’s body rejecting the new kidney after a transplant.

In this new study, researchers from the University of Southern California looked at the vitamin D levels of 53 patients who had received kidney transplants in 2013.

They found that 26 patients had levels between 10 and 20 ng/ml, 17 patients had levels between 20 and 30 ng/ml, and only 9 patients had levels above 30 ng/ml.

“Our initial data suggests that approximately 83 percent of our transplant populations is vitamin D deficient four weeks after transplantation. These results were surprising, as most of these patients were taking vitamin D supplements,” said lead researcher Dr. Rahul Dhawan. “It shows us that we need to be even more aggressive in recognizing and treating deficiency.”
