About this study
Official title: Effectiveness of Oral Melatonin as an Adjunct to Standard Treatment in Adults With Atopic Dermatitis: A Randomized Controlled Trial
Atopic dermatitis is a chronic inflammatory skin disease that is commonly associated with itching, sleep disturbance, and impaired quality of life. Melatonin may have beneficial effects on sleep, inflammation, and oxidative stress.
This randomized controlled trial will evaluate the effectiveness of oral melatonin as an adjunct to standard treatment in adults with atopic dermatitis. A total of 130 participants will be randomly assigned in a 1:1 ratio to receive either standard treatment according to the Vietnamese Ministry of Health 2023 guideline or standard treatment plus oral melatonin 6 mg once daily for 4 weeks.
Atopic dermatitis severity will be assessed using the SCORing Atopic Dermatitis (SCORAD) index, and sleep quality will be evaluated using the Pittsburgh Sleep Quality Index (PSQI). Serum superoxide dismutase and melatonin concentrations will also be measured to assess changes related to oxidative stress and melatonin status. Participants will be evaluated at baseline and during the 4-week treatment period.
Read the detailed description
Atopic dermatitis is a chronic, relapsing inflammatory skin disease characterized by pruritus and inflammatory skin lesions. Sleep disturbance is common in patients with atopic dermatitis and may be related to both disease activity and alterations in circadian and oxidative stress pathways.
Melatonin is involved in the regulation of the sleep-wake cycle and also has antioxidant, anti-inflammatory, and immunomodulatory properties. These effects provide a biological rationale for evaluating melatonin as an adjunctive treatment in atopic dermatitis.
In this study, adults diagnosed with atopic dermatitis who meet the eligibility criteria will be randomly allocated to one of two parallel treatment groups. The control group will receive standard treatment for atopic dermatitis according to the Vietnamese Ministry of Health 2023 guideline. The experimental group will receive the same standard treatment plus oral melatonin 6 mg once daily, taken approximately 60 minutes before bedtime.
Participants will be followed for 4 weeks. Clinical disease severity will be assessed using the SCORAD index at baseline, Week 2, and Week 4. Sleep quality will be evaluated using the PSQI at baseline and Week 4. Serum superoxide dismutase and melatonin concentrations will be measured before treatment and after 4 weeks of treatment. Adverse effects occurring during treatment will also be recorded.
The study will compare changes in clinical severity, sleep quality, and biological markers between the two treatment groups to determine whether adjunctive oral melatonin provides additional benefit over standard treatment alone.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in SCORAD Score From Baseline to Week 4
Atopic dermatitis severity will be assessed using the SCORing Atopic Dermatitis (SCORAD) index. The total SCORAD score ranges from 0 to 103, with higher scores indicating greater disease severity. The change in total SCORAD score from baseline to Week 4 will be compared between the standard treatment group and the standard treatment plus melatonin group.
Measured: Baseline to Week 4
Secondary outcomes (6)
Change in SCORAD Score From Baseline to Week 2
Atopic dermatitis severity will be assessed using the SCORing Atopic Dermatitis (SCORAD) index. The change in total SCORAD score from baseline to Week 2 will be compared between the standard treatment group and the standard treatment plus melatonin group. Higher SCORAD scores indicate greater disease severity.
Measured: Baseline to Week 2
Change in Pittsburgh Sleep Quality Index Score From Baseline to Week 4
Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). The total score ranges from 0 to 21, with higher scores indicating poorer sleep quality. Change from baseline to Week 4 will be compared between treatment groups.
Measured: Baseline to Week 4
Change in Serum Superoxide Dismutase Concentration From Baseline to Week 4
Serum superoxide dismutase concentration will be measured before treatment and after 4 weeks to evaluate changes in oxidative stress-related antioxidant status.
Measured: Baseline to Week 4
Change in Serum Melatonin Concentration From Baseline to Week 4
Serum melatonin concentration will be measured before treatment and after 4 weeks. Changes from baseline will be evaluated and compared between treatment groups.
Measured: Baseline to Week 4
Clinical Treatment Response According to SCORAD
Treatment response will be categorized according to the study protocol as good, moderate, or poor/no response based on improvement in clinical manifestations, change in total SCORAD score, and change in disease severity category.
Measured: Week 2 and Week 4
Adverse Events During Treatment
The number and proportion of participants experiencing treatment-related adverse effects, including adverse effects associated with melatonin and concomitant treatments, will be recorded.
Measured: Baseline through Week 4
