Diabetes
represents an extremely large problem in today’s society,
affecting approximately 25 million people. There are a large
number of complications associated with diabetes, including
increased heart disease and stroke caused by the narrowing of
blood vessels due to fat deposits, leading to restricted blood
flow. When severe, this restricted blood flow can lead to
critical limb ischemia (CLI). This in turn can lead to nerve
damage, ulcers or foot wounds that won’t heal and potentially,
amputation. Indeed, 90% of lower extremity amputations results
from non-healing wounds and 17% of diabetic patients will
develop a foot ulcer within 3 years.
During diabetes, biologically available NO is greatly
reduced resulting in defective blood vessel function and blunted
wound healing responses. Recent studies from Dr. Kevil’s
laboratory show that nitrite therapy significantly enhances
diabetic ischemic hind limb blood flow and enhances wound
healing responses.
Images to the left readily demonstrate that
diabetic wounds treated with vehicle control remain open and
poorly healed 14 days after injury. Conversely, daily nitrite
therapy significantly enhances closure of diabetic wounds and
restoration of tissue perfusion. These exciting discoveries
provide the foundation for our second product, a nitrite agent
which shows great potential for the treatment of diabetic
ulcers, chronic wound management and many other applications.
