kidney failure | Wellness Secrets of a SuperAger

Full disclosure, I love coffee and coffee drinks like latte’s and cappucino. I drink more than one cup every day of my life.

If you need another reason to start the day drinking a cup of joe, a recent study by Johns Hopkins Medicine researchers has revealed that consuming at least one cup of coffee a day may reduce the risk of acute kidney injury (AKI) when compared to those who do not drink coffee.

The findings, published May 5 in the journal Kidney International Reports, show that those who drank any quantity of coffee every day had a 15% lower risk of AKI, with the largest reductions observed in the group that drank two to three cups a day (a 22%–23% lower risk).

“We already know that drinking coffee on a regular basis has been associated with the prevention of chronic and degenerative diseases including type 2 diabetes, cardiovascular disease and liver disease,” says study corresponding author Chirag Parikh, M.D., Ph.D., director of the Division of Nephrology and professor of medicine at the Johns Hopkins University School of Medicine. “We can now add a possible reduction in AKI risk to the growing list of health benefits for caffeine.”

A new study finds that heart disease may increase your chances of kidney failure.

• In adults followed for a median of 17.5 years, cardiovascular diseases—including heart failure, atrial fibrillation, coronary heart disease, and stroke—were each linked with a higher risk of developing kidney failure.

• Heart failure was associated with the highest risk: adults hospitalized with heart failure had an 11.4-times higher risk of developing kidney failure than individuals without cardiovascular disease

New research indicates that cardiovascular diseases—including heart failure, atrial fibrillation, coronary heart disease, and stroke—are each linked with a higher risk of developing kidney failure. The findings, which appear in an upcoming issue of the Journal of the American Society of Nephrology, highlight the importance of protecting the kidney health of individuals diagnosed with cardiovascular disease.

The heart and the kidneys have a bi-directional relationship, whereby dysfunction in either may compromise the function of the other. Many studies have investigated the risks of kidney disease on heart health, but few have examined the reciprocal relationship.

To investigate, a team led by Kunihiro Matsushita, MD, PhDand Junichi Ishigami, MD, PhD(Johns Hopkins Bloomberg School of Public Health)examined information on 9,047US adults who did not have signs ofheart disease when they enrolled in a community-based study.

“Many physicians probably recognize that patients with cardiovascular disease are at risk of kidney disease progression, but to my knowledge, this is the first study quantifying the contribution of different cardiovascular diseases to the development of kidney failure, said Dr. Matsushita.
