Clinical Trial Summary

Background: Scabies is a skin disease due to Sarcoptes scabiei. The transmission risk is high among communities living together, such as dormitories, boarding schools, nursing homes, and so on. Blacksoap® is a soap product that is recognized as adjuvant therapy. Until now, there has been no research on the effectiveness and side effects of using Blacksoap®. Purpose: This research aimed to assess the cure rate of standard scabies treatment, with and without Blacksoap®, to determine pruritus visual analog scale (VAS) score, transepidermal water loss (TEWL) score before and after receiving therapy, and to evaluate the side effects of the treatment. Methods: The intervention group obtained standard therapy and Blacksoap®; meanwhile, the control group received standard therapy and baby soap.

Description:

This study is a single-blind randomized clinical trial on scabies patient population at Pondok Pesantren Al Islami, Cibinong, Bogor. It is part of a research and social service by the Dermatology and Venereology Department of Faculty of Medicine Universitas Indonesia / dr. Cipto Mangunkusumo National Central General Hospital entitled "Early Detection of Scabies and Other Dermatoses and Evaluation of Scabies Treatment in Al-Hidayah and Al Islami Islamic Boarding School" Research subjects who are participating are those diagnosed with scabies (fulfilling 2 out of 4 cardinal signs of scabies).

The research was conducted from September to October 2018 with the entire scabies patient in Indonesia as the target population, and all students at Al Islami Boarding School who at the time had scabies as the accessible population. A random cluster sampling was done on the population member diagnosed with scabies based on the boarding school building location into the intervention group and control group. The intervention group was receiving permethrin 5% cream and Blacksoap®, while the control group was receiving permethrin 5% cream and baby soap.

Skin scraping examination was done on the research subjects with potassium hydroxide (KOH) solution to find the mites, alongside pruritus visual analog scale (VAS) score assessment and transepidermal water loss (TEWL) measurement before suitable therapy given. In the first and fourth weeks after the initial assessment, which includes the scabies cure rate, pruritus VAS score, TEWL score, and side effects evaluation, a follow-up was conducted. TEWL was measured using Tewameter® TM 300 made by Courage-Khazaka from Germany. Subsequent data were documented and processed using Statistical Product and Service Product (SPSS) program version 20. Finally, an analysis was done by a third-party which did not seem aware of the treatment given (single-blind).
