Abstract
Background:
In the last decade, a number of studies have examined the relationship between serum vitamin D concentration and the risk of cerebrovascular events. Besides vitamin D, the latest evidence shows that vitamin A is also a risk factor for cerebrovascular disease. Vitamin A and its derivatives act biologically via specific nuclear receptors that regulate gene transcription. Vitamin A receptors can also interact with other nuclear receptors that have neuroprotective effects such as vitamin D, against stroke. Although many studies suggested the synergism of vitamin A and D, there is still no study that evaluates their levels simultaneously in acute phase ischemic stroke, and the relationship to outcome.
Objective:
The objective of this study was to analyze the correlation between serum vitamin A and D levels on admission in Acute Ischemic Stroke patients and clinical outcome by using the National Institutes of Health Stroke Scale (NIHSS).
Methods:
A prospective cohort study was conducted, and samples were followed since the diagnosis of acute-phase Ischemic Stroke was established until the clinical outcome of day 14 after stroke onset. A total of 50 subjects enrolled for this study would be examined for serum levels of vitamins A and D on admission, and on the 14th day were assessed for NIHSS as a clinical outcome.
Results:
From 50 research subjects, the mean of vitamin A and D level in the acute phase of Ischemic Stroke was 463.35 ± 116.97 µg/L and 21.65 ± 6.51 ng/mL, respectively. By using the Spearman’s correlation test, it was found that the acute phase vitamin A level and NIHSS on day 14 had a significant and strong correlation with p = 0.045 (r = -0.672). Along with it, vitamin D serum levels and NIHSS also had a significant and strong correlation with p = 0.026 (r = -0.754). Both of these results showed that vitamin A and D had an inverse association with NIHSS, meaning that the higher vitamin A and D serum levels, the better the clinical outcome would be.
Conclusion:
Both serum vitamin A and D levels in the acute phase of Ischemic Stroke was correlated strongly with short time clinical outcome. The higher vitamin A and D serum levels in the acute phase, the better the clinical outcome would be for Ischemic Stroke patients.
