Comparison of Keloid Volume and Symptoms Reduction Between Intralesional Umbilical-Cord Mesenchymal Stem Cells, Its Conditioned Medium, and Triamcinolone Acetonide Injection as Keloid Therapy: A Randomised Controlled Trial
Comparison of Keloid Volume and Symptoms Reduction Between Intralesional Umbilical-Cord Mesenchymal Stem Cells, Its Conditioned Medium, and Triamcinolone Acetonide Injection as Keloid Therapy: A Randomised Controlled Trial
This study is a double-blind randomized controlled trial (RCT) examining the effect of intralesional injection of umbilical cord-derived mesenchymal stem cells (UC-MSC), umbilical cord-derived conditioned medium (UC-CM), or triamcinolone acetonide (TA) on keloids carried out using CONSORT statement. Research is directed at studying keloid volume reduction and changes in POSAS score.
Patients were screened initially by measuring the length and thickness of the keloids using a ruler. Patients who met the study inclusion criteria were randomly divided into three groups. Each patient in the groups was given the same injection volume (1 mL) in every cm3 keloid volume using a 1 mL syringe and 27G needle. The injections were ultrasound-guided into the center of the lesion with a 30-45-degree angle using an in-plane technique, therefore the same pressure. Group 1 was given umbilical cord-derived mesenchymal stem cells (UC-MSC) 2 million cells/mL/cm3, group 2 was given umbilical cord-derived conditioned medium(UC-CM) 1 mL/cm3, and group 3 was given triamcinolone acetonide (TA) 40 mg/mL/cm3. All patients received a single dose and 1 booster dose. The percentage of keloid volume regression in each treatment group was calculated by calculating the difference in volume before and after therapy with a 3-dimensional CT-scan, then expressed as a percentage. The CT-scan volume was obtained with the SmartVitrea application (Figure 2), then a POSAS examination will be carried out for subjective and objective assessment.
