Common virus may be cause of high blood pressure

High blood pressure can lead to an increased risk for heart disease, stroke and kidney disease with 1 in 20 adults in the UK being affected and as many as 70 percent of adult diabetics. It’s causes can be varied, from genetic predisposition, medical conditions and stress, but now there may be a completely different explanation. Researchers at Beth Israel Deaconess Medical Center believe that a common viral infection might also be a cause.

The virus in question is cytomegalovirus, part of the herpes family, and it infects between 40 and 80 percent of adults worldwide. It is spread through bodily fluids such as saliva and urine, and can be transmitted from person to person through close bodily contact. Like most other herpes-type viruses, once you’re infected by CMV it will remain dormant in your body for the rest of your life, though you may never show any symptoms. If a woman has CMV it can be passed on to her unborn child and it is estimated that one in every 200 babies will be born with congenital CMV.

Viruses have the ability to turn on human genes and, in this case, the CMV virus is enhancing expression of renin, an enzyme directly involved in causing high blood pressure a whole new approach to treating hypertension, with anti-viral therapies or vaccines becoming part of the prescription.”

This breakthrough came about because for the first time researchers were brought together from a combination of disciplines including allergies, cardiology, infectious diseases and pathology. This collaborative venture meant that insights were shared and led to a statement from author Clyde Crumpacker, MD the co-author of the study and Professor of Medicine at Harvard Medical School that.. “This new discovery may eventually provide doctors with a whole new approach to treating hypertension, with anti-viral therapies or vaccines becoming part of the prescription.”
