Modification of the current screening criteria are needed for diagnosing patients with autosomal dominant polycystic disease (ADPKD), according to a study appearing in the January 2009 issue of the Journal of the American Society Nephrology (JASN). The results suggest that some patients with a milder form of the disease may otherwise be misdiagnosed.

The Stowers Institute’s Rong Li Lab has discovered that a protein previously shown to have a role in inflammation may also have a role in the formation of cysts in Autosomal Dominant Polycystic Kidney Disease (ADPKD) — one of the most common life-threatening genetic diseases — and has shown that a drug inhibiting the protein can slow the disease in mice.

Gender influences the prevalence and progression rate of many renal diseases, such as polycystic kidney disease (PKD). The physiology behind gender differences and renal disease is still uncertain, but the distinct characteristics of male and female kidney size, along with diet and the presence of hypertension, have all been thought to play a part.

Using a compound from a centuries-old Chinese traditional medicine, Yale University researcher Dr. Craig Crews has been able to prevent the formation of kidney-destroying cysts in a mouse model of polycystic kidney disease. This ability holds out hope for what would be the first treatment, other than kidney transplant or frequent dialysis, for one of the most lethal of all kidney diseases worldwide.
