Could vitamin C treat intensive care patients with sepsis?
Study into vitamin C’s effectiveness in treating intensive care patients.
A Christchurch researcher is doing New Zealand’s first study of vitamin C's potential as a treatment for intensive care
patients with sepsis.
Dr Anitra Carr is doing the clinically-relevant work with support from the Health Research Council (HRC). She was
recently awarded a $500,000 Sir Charles Hercus Health Research Fellowship for promising emerging researchers.
Dr Carr works at the University of Otago's Christchurch health campus with its Centre for Free Radical Research.
She says sepsis is the main cause of death in intensive care patients. Rates are increasing and treatment options for
the life-threatening condition are limited. Patients with severe sepsis often develop cardiac dysfunction and
dangerously low blood pressure (known as septic shock) and are given drugs to stabilize their cardiovascular function.
Dr Carr’s hypothesis is that cardiac dysfunction, and resulting drug treatments, could be avoided if patients had
appropriate vitamin C levels. When sepsis patients experience cardiac problems, they are often given drugs to stimulate
the cardiovascular system. Dr Carr says vitamin C is potentially involved in a similar natural process, and if levels
were high enough patients might not need as much medication.
Dr Carr will carry out a clinical trial in Christchurch where people with sepsis are given the vitamin to see if this
intervention results in a better recovery or survival. She will be trying to find out whether the positive biological
effects of vitamin C translate into an improvement in patient outcome, which has been reported in a smaller study
overseas. Her study will also involve comparing vitamin C levels with severity of illness and whether this contributes
to progression of sepsis.”
HRC Chief Executive Professor Kath McPherson says the Sir Charles Hercus fellowship is a really important opportunity
for New Zealand’s up-and-coming scientists to consolidate their research career, and “we’re delighted to be able to
support Anitra in this way.”
Dr Carr says she is very grateful to the HRC for the funding that will allow her to carry out clinical research that
will have a positive impact on the outcomes of critically ill people and potentially even save lives.
