Comparison of Intralesional Vitamin D with Intralesional Triamcinolone Acetonide in the Treatment of Keloids.

Abstract

Background: Hypertrophic scars and keloids are disorders caused by the excessive growth of connective tissue, associated with the accumulation of collagen and cellular matrix components. These scars are caused by abnormal wound healing and can have a great impact on patients' lives. Therefore, we aimed to compare the effect of intralesional injection of vitamin D with triamcinolone acetonide in the treatment of keloid.

Methods: This study was a one-sided blind clinical trial, conducted on 22 patients (44 samples) with keloid. It was a randomized, blinded clinical trial, conducted in Imam Khomeini Hospital in Ahvaz, Iran in 2022. In each group, triamcinolone or vitamin D was injected at the lesion site with an interval of three weeks and an average of 6 sessions. The patients were re-evaluated 3 months after the end of the treatment in terms of recurrence.

Results: By examining the VSS scale in each of the groups, this scale decreased significantly in both groups after the intervention (P=0.001), which was greater in the group receiving triamcinolone (P=0.001).

Conclusion: It seems that the injection of vitamin D at the site of the lesion helps to treat it, but the effectiveness of the usual triamcinolone treatment was still higher, it is suggested to use vitamin D as an adjunctive treatment in these patients.
