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.

About this study

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.

Treatment and study plan

umbilical cord-derived mesenchymal stem cells (UC-MSC)

Biological

Group 1 was injected UC-MSC 2 million cells/mL/cm3, 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.

umbilical cord-derived mesenchymal stem cells conditioned medium (UC-CM)

Biological

Group 2 was injected UC-CM 1 mL/cm3, 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.

Triamcinolone Acetonide (TA)

Drug

Group 3 was injected TA 40 mg/mL/cm3, 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.

Primary outcomes

  1. Keloid volume reduction

    Time frame: 15 weeks

    Volume was measured by CT-scan 2 weeks and 17 weeks after the first visit

  2. The Patient and Observer Scar Assessment Scale (POSAS) score reduction

    Time frame: 17 weeks

    Symptoms were measured using The Patient and Observer Scar Assessment Scale (POSAS) on the first visit, five weeks, 13 weeks, and 17 weeks after the first visit. Each item of the POSAS is rated on a 10-point score. The lowest score is '1', corresponding to the normal skin situation (i.e., normal pigmentation, no itching). Score 10 equals the most significant difference from normal skin (i.e., the worst imaginable scar or sensation). The symptoms are considered improved if the score gets lower. The total score of both scales can be calculated by summing up the scores of each of the six items. The total score can range from 6 to 60.
