A study found that kidney transplants performed in Europe have higher survival rates after 5 and 10 years compared to those in the United States. The disparity may be attributed to the lack of cost reimbursement for anti-rejection drugs in the US, leading to poorer outcomes among certain demographics.
A single gene variant in donors has been linked to a 69% increased risk for long-term failure of transplanted kidneys. The variant affects the expression of the protein that pumps drugs out of cells, which can be toxic to the kidneys.
A study found that variations in the APOL1 gene are associated with non-diabetic kidney disease in African-Americans, but not all carriers develop the disease. Researchers suggest that environmental or viral infections may play a role in triggering the disease.
