Clinical Trial Summary

The objectives are to compare the efficacy of pre and post-treatment and between 5% losartan potassium loaded in ethosomal gel and 10 mg/ml triamcinolone acetonide injection based on the indicator score of The patient and observer scar assessment scale 3.0 (POSAS 3.0), degree of erythema and pigmentation, area size, thickness and density of human keloids.

Description:

After being informed about the study and the associated risks and benefits, participants will be randomly allocated to one of two groups, each consisting of 23 individuals. After being informed about the study and the associated risks and benefits, participants will be randomly allocated to one of two groups, each consisting of 23 individuals. One group will receive the topical application of 5% losartan gel, while the other will receive an injection of triamcinolone acetonide 10mg/ml. After being informed about the study and the associated risks and benefits, participants will be randomly allocated to one of two groups, each consisting of 23 individuals. To measure the subjective and objective changes that occur in the keloid before and after treatment, outcome assessors will be blinded. Measurements will be taken four times over the course of three months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The patient and observer scar assessment scale score (POSAS 3.0)	The Patient and Observer Scar Assessment Scale 3.0 consists of sixteen items of the patient questionnaire (PSAS) with maximum and minimum values are 80 and 16, consecutively; and seven items of the observer questionnaire (OSAS) with maximum and minimum values are 35 and 7, consecutively. The lower score, the better result of the keloid.	change from baseline the POSAS score at 4,8, and 12 weeks, consecutively.
Secondary	Degree of erythema and hyperpigmentation	The colors are taken using dermoscopy and quantifiably analysed using image analysis ImageJ	change from baseline the degree of erythema and hyperpigmentation at 4, 8 and 12 weeks, consecutively.
Secondary	the width of the keloid surface area (mm2)	The surface area is taken by digital photography and quantifiably analysed using image analysis ImageJ	change from baseline width of keloid surface area at 4, 8 and 12 weeks, consecutively.
Secondary	The thickness of keloid (mm)	The thickness of the keloids is assessed using high-frequency ultrasonography	change from baseline thickness of keloid at 4, 8 and 12 weeks, consecutively.
Secondary	The degree of pliability of keloid (durometer unit)	The pliability of keloids is assessed using durometer shore type oo (Teclock Japan)	change from baseline pliability at 4, 8 and 12 weeks, consecutively.
