Brief Summary

The goal of this clinical trial is to learn if drug bleomycin intralesionally is beneficial than intralesional 5FU and Triamcinolone Acetonide in treating Keloids. The main questions it aims to answer are: Does drug Bleomycin injected intrasleisonally lower the time duration to effectively treat the keloids in participants as compared to intralesional Triamcinolone Acetonide and 5-Flourouracil? Researchers will compare drug Bleomycin and 5FU plus Triamcinolone Acetonide and determine if bleomycin is better. Participants will: Treatment will be given in two groups by a researcher blinded of the treatment being given in each group. POSAS patient and observer scar scale will be used to assess the keloids at 0, 2, 4, 6, 8, 10, and 12 weeks and during follow ups afterwards, assessments will be carried out by another researcher who will assess the improvement on the scale of 0-no improvement, to excellent-75-100% improvement in terms of POSAS variables. Effectiveness will be indicated by 50% reduction in POSAS score from the baseline.

Outcome Measures

Primary Outcomes (2)

• The Efficacy in terms of POSAS SCAR SCALE of Intralesional Bleomycin as compared to 5-fluorouracil (5-FU) and Triamcinolone Acetonide(TAC) for the treatment of Keloids: A Randomized Control Trial

  The observer scale of the POSAS consists of six items (vascularity, Pigmentation, thickness, relief, pliability and surface area). All items are scored on a scale ranging from 1 ('like normal skin') to 10 ('worst scar imaginable').The sum of the six items results in a total score of the POSAS observer scale.

  12 weeks

• efficacy of intralesional bleomycin and combination of triamcinolone acetonide and 5-flourouracil in treating keloids, comparing the scar reduction in accordance with the patient and observer scar (POSAS) scale in two groups.

  Efficacy will be assessed by comparing the scar reduction on in accordance with the patient and observer scar (POSAS) scale in two groups. 50% reduction in score from baseline indicates that treatment is affective . It will be assessed at twice weekly interval till 12 weeks.

Study Arms (2)

The Efficacy of Intralesional Bleomycinin treatment of keloids

EXPERIMENTAL

Group B will be given injection Bleomycin 1.5 IU /ml (15 units vial dilution in 10ml Normal saline) 1 ml of this 1cm apart intralesionally as 0.1- 0.2ml/cm2 with max dose of 5ml per session and repeat after 2 weeks. Treatment will be given in two groups by a researcher blinded of the treatment being given in each group. POSAS patient and observer scar scale will be used to assess the keloids at 0, 2, 4, 6, 8, 10, and 12 weeks and during follow ups afterwards, assessments will be carried out by another researcher who will assess the improvement on the scale of 0-no improvement, to excellent-75-100% improvement in terms of POSAS variables.

Drug: intralesional bleomycin

The Efficacy of 5-fluorouracil (5-FU) and Triamcinolone Acetonide in treatment of keloids

EXPERIMENTAL

Group A will be given 1ml if 0.9ml/22.5mg (25mg/ml) of 5-FU with 0.1 ml/4mg (40mg/ml) of Triamcinolone Acetonide, intralesionally 1cm apart, as 0.1- 0.2ml/cm2 with max dose of 5ml per session and repeat after every 2 weeks.

Drug: 5-flourouracil and triamcinolone acetonide

Interventions

intralesional bleomycin DRUG

The role of intralesional bleomycin for the treatment of keloids needs further establishment in terms of effective concentration, number of sessions and post treatment ulceration or/and hypopigmentation. Additionally, its comparison to the commonly used and proven, more effective combination than intralesional steroid alone i-e 5-FU in combination with the intralesional steroid, need also be done so that if found affective will be able to deal with the pathological scar as a 1 st line therapeutic drug. With a strong study design and an adequate sample size, and particularly in a specialized tertiary care clinical setup, Our study, seeks to get over the aforementioned limitations, and will delineates the appropriate guidelines for the management of these pathological scars, and suggest option with the best outcomes, as well as lesser side effects and recurrence rates.
