Description:
Background: Vitamin C (ascorbic acid) is a micronutrient imperative for many bodily functions,
with research revealing its functional support of leukocytes. The purpose of this meta-analysis
was to determine the effects of surgery on leukocyte vitamin C concentrations by assessing the
amount and longevity of post-operative leukocyte vitamin C change.
Methods: We searched the PubMed, Scopus and the Cochrane Library databases for relevant
research papers. Studies were included until January 2022, with no time limits. Studies that
reported means and standard deviations of leukocyte/buffer layer vitamin C concentrations
before and after surgery were included into the meta-analysis. The meta-analysis comprised of
eight studies.
Results: Seven studies (which included eight individual studies) were included into our metaanalysis. Combined data from the meta-analysis displayed a significant depletion in mean
leukocyte vitamin C concentrations during the first 24 hours following the surgery by a mean
of 5.37 µg/108
(32.3%) (CI = -6.35, -4.40) (n = 6, p < 0.001) and during the first post-operative
week by 4.43 µg/108
(23%) (-7.27, -1.58) (n = 7, p < 0.001). However, this depletion was followed
by an uprise in mean ascorbic acid leukocyte concentrations of 0.93 µg/108
(4.8%) (-0.79, 2.66)
(n = 6, p = 0.29) at 7 days (or beyond) post-operatively.
Conclusion:Significant post-operative leukocyte vitamin C depletions were particularly observed
during the first post-operative week. Further research is required to validate the observed
results and to determine whether the observed depletions may be linked to compromised
immunological function and pathophysiologies that arise during the post-operative period.
