July 18, 2026 updated by: nirmeen amr habib, Ain Shams University

Effect of Melatonin Administration on the Clinical Outcomes of Systemic Lupus Erythematosus Patients

The aim of the current study is to evaluate the effect of melatonin administration on circulating levels of inflammatory mediators, oxidative stress, sleep quality, fatigue and quality of life in patients with SLE. To the best of our knowledge, this is the first randomized-controlled trial to evaluate the impact of melatonin on sleep quality and assess fatigue and quality of life in SLE adult patients. Moreover, the impact of melatonin on serum concentrations of Interleukin-6 and superoxide dismutase SOD will be evaluated.

Detailed Description

Systemic lupus erythematosus (SLE) is a multisystem chronic autoimmune disease with a relapsing and remitting course. Its prevalence is higher in women of childbearing age of non-white ethnicity. It has a broad spectrum of clinical features ranging from mild cutaneous involvement to severe organ damage, such as kidney failure, pulmonary hypertension, and cardiac failure. The exact etiology of the disease is not well understood well. However, inflammation and oxidative stress are among the most important targets for the management of SLE. Elevated circulating IL-6 concentrations have been consistently observed in patients with systemic lupus erythematosus (SLE) relative to healthy controls, underscoring its pathogenic relevance. In systemic lupus erythematosus (SLE), excessive oxidative stress arising from chronic inflammation and immune complex deposition leads to depletion of endogenous antioxidants, including SOD.

Moreover, diminished SOD activity correlates with disease activity indices such as SLEDAI, suggesting its potential utility as a biomarker for oxidative stress-related disease burden.

melatonin has anti-inflammatory and anti-oxidant characteristics that may aid in the management of autoimmune diseases. In different animal models, melatonin has demonstrated to ameliorate lupus nephritis, reduce inflammation, and improve overall disease pathology. However, these studies have their limitations of being performed in vitro.Only one randomized controlled trial (RCT) was conducted on adult SLE patients and showed improvement in oxidative stress markers, namely malondialdehyde and total antioxidant capacity but no effect on disease activity.

The aim of the current study is to evaluate the effect of melatonin administration on circulating levels of inflammatory mediators, oxidative stress, sleep quality, fatigue and quality of life in patients with SLE. To the best of our knowledge, this is the first randomized-controlled trial to evaluate the impact of melatonin on sleep quality and assess fatigue and quality of life in SLE adult patients. Moreover, the impact of melatonin on serum concentrations of Interleukin-6 and superoxide dismutase SOD will be evaluated.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Serum Interleukin- 6 (IL-6)
Time Frame: at baseline and then after 12 weeks
Blood samples will be drawn from the patients at baseline and after 12 weeks of intervention. Blood samples will be collected at baseline, centrifuged and stored as serum at - 80°C or -20°C until analysis. Enzyme-linked immunosorbent assay (ELISA) method will be used to measure Interleukin 6 concentrations
at baseline and then after 12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
SLEDAI -2K Score
Time Frame: at baseline and then after 12 weeks

A)Items: It includes 24 items, with 16 clinical and 8 laboratory-based descriptors.

B)Domains: The items are grouped into nine organ systems: central nervous system, vascular, musculoskeletal, serosal, dermal, constitutional, renal, immunological, and hematological.

C)Scoring: Each item is scored as present or absent, typically based on the preceding 30 days.

D)Total Score: The individual item scores are summed to produce a global score, ranging from 0 to 105.

at baseline and then after 12 weeks
Serum SOD
Time Frame: at baseline and after 12 weeks
Superoxide dismutase (SOD) measured by Spectrophotometric Method, by tracking the inhibition of superoxide radical-driven reactions, often involving the reduction of nitro blue tetrazolium (NBT) or the autoxidation of other compounds like BXT-01050, which produce a color change that is measured at a specific wavelength, typically around 525 nm or 560-562 nm. The rate of this color change in the presence of a sample is compared to the rate in a blank, with the percent inhibition of the reaction directly correlating to the amount of SOD present in the sample.
at baseline and after 12 weeks
Arabic version form of Systemic Lupus Erythematosus-Specific Quality of Life Questionnaire (SLEQOL-Arabic Version)
Time Frame: at baseline -1st Month-2nd Month-3rd Month

The questionnaire consists of 40 items covering multiple domains relevant to SLE. These items are grouped into 6 domains which are:

  1. Physical functioning / mobility
  2. Role limitation / daily activities
  3. Self-image / appearance
  4. Emotional / mood
  5. Symptoms 6_Social / interpersonal relations Each of the 40 items is rated using a 7-point Likert scale (1=Not at all affected and 7=Extremely affected). Higher scores generally reflect poorer QoL.
at baseline -1st Month-2nd Month-3rd Month
Arabic version of Fatigue Severity Scale (FSS)
Time Frame: at baseline -1st Month-2nd Month-3rd Month
FSS is a self-reported questionnaire that is simple and easy to use. It consists of 9 statements that rate the severity of the patient's fatigue symptoms in terms of how these symptoms affect motivation, exercise, physical function, and activities of daily living Reflecting on their condition over the past month, patients score each item from 1 to 7, based on the extent, to which they agree or disagree with each statement (1 = strong disagreement, 7 = strong agreement).
at baseline -1st Month-2nd Month-3rd Month
Arabic Version of the Pittsburgh Sleep Quality Index (PSQI)
Time Frame: at baseline- 1st Month-2nd Month-3rd Month
The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Nineteen individual items generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these seven components yields one global score. Each weighed equally on a O-3 scale. The seven component scores are then summed to yield a global PSQI score, which has a range of O-2 I; higher scores indicate worse sleep quality.
at baseline- 1st Month-2nd Month-3rd Month
Incidence of Adverse Effects and Medication Adherence & Modifications
Time Frame: weekly up to 12 weeks
All patients in both arms will be followed weekly by a telephone call for reporting of any adverse effects from melatonin and patients will be given a side effect-reporting card and will be educated on how to use it. Moreover, compliance to medications and any change of doses or addition or discontinuation of medications will be assessed.
weekly up to 12 weeks
