Kidney Disease In Kids Linked To Maternal Diabetes, Obesity

A new study has found that kids with Chronic Kidney Disease (CKD) are more likely to have mothers who were obese or had diabetes during pregnancy.

The study by Christine W. Hsu, (University of Washington, Seattle) and colleagues included more than 4,000 patients with childhood CKD-diagnosed at age 21 or younger-in Washington State.

These patients were compared to more than 20,000 healthy children to evaluate possible relationships between a pregnant woman having diabetes, being obese or overweight, and the risk of her child developing CKD anytime during infancy, childhood, or adolescence.

The overall rate of childhood CKD was approximately 0.26 percent-about 1 case per 400 live births.

When investigators adjusted for length of gestation, CKD risk was 69 percent higher for children whose mothers had diabetes before pregnancy.

Cysts - Dysplastic Kidneys
Ultrasound scan reveals multiple cysts and there is no function on that kidney when tested on DMSA scan. A vast majority of them resolve spontaneously.

For children whose mothers developed diabetes during pregnancy (gestational diabetes), there was a 28 percent increase in CKD risk.

Children of obese mothers demonstrated a 22 percent increase in CKD risk.

When specific causes of kidney disease were analyzed, children whose mothers had diabetes before pregnancy had nearly a 700 percent increase in the risk of kidney-related birth defects (renal aplasia/dysplasia).

"Developmental abnormalities of the kidney and urinary tract are the most common cause of childhood CKD," Hsu explains.

Top Ten Facts About Diabetes
Diabetes or diabetes mellitus, is an endocrine and metabolic disorder characterized by high blood sugar levels (hyperglycemia) over a prolonged period of time.

The risk of urinary blockage (obstructive uropathy) -which can lead to CKD-was increased by 34 percent for children whose mothers had gestational diabetes, 23 percent in those whose mothers were obese, and 21 percent in those whose mothers were overweight but not obese.

In adults, CKD is often related to medical conditions like diabetes and high blood pressure. In contrast, according to Hsu, "Development of childhood CKD may be programmed prenatally." Few studies have looked at possible risk factors for CKD development before adulthood.

"Our research shows that childhood CKD is modestly associated with maternal diabetes and maternal overweight or obesity, with the strongest association between abnormal kidney development and maternal diabetes," says Hsu.

The study has been presented at the American Society of Nephrology's 43rd Annual Meeting and Scientific Exposition.
