Clinical Trial Summary

The purpose of this study is to investigate the effects of a type of non-invasive transcranial alternating current stimulation (tACS) on patients diagnosed with systemic lupus erythematosus (SLE) who are experiencing depression.

Targeting depression in patients with SLE may provide benefit to these patients, as there is a clear relationship between chronic pain and depression. The investigators propose that a tACS stimulation montage that was previously used in depression could be beneficial to patients with SLE, resulting in reduced depression symptoms, thus resulting in reduced chronic pain and cognitive difficulties.

Description:

At the initial session, consent will be obtained and eligibility will be determined.

Eligible participants will undergo a structural MRI as part of the screening process, then be randomized and have 5 consecutive daily, 40 minute stimulation sessions.

Participants will be randomly assigned to one of three groups: sham stimulation, individualized alpha-tACS (usually 8-12 Hz), or individualized theta-tACS (individualized alpha frequency minus 4 Hz). Participation will include 1 to 11 visits.

Neurophysiological measures will be taken before and after the stimulation sessions on the first and fifth days of the intervention, as well as the 2-week follow-up and 4-week follow-up visits. Psychiatric clinical assessments will be performed at baseline (Day 1 of stimulation), Day 5 of stimulation, and at both follow-up visits using the Hamilton Depression Rating Scale (HDRS17), the Hamilton Anxiety Rating Scale (HAM-A), the Inventory of Depression and Anxiety Symptoms (IDAS), and the Comparative Pain Scale Chart. All participants will also be asked to complete self-report surveys via REDCap at a 3-month time point measured from completion of the intervention.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change in correlation between frontal midline alpha and theta activity (as measured from EEG recordings) and accuracy at cognitive tasks tasks.	Participants will complete various tasks paired with electroencephalogram (EEG) recordings to assess physiological changes. Participants will be asked to perform sustained attention, selective attention, and working memory tasks with EEG recordings.	Day 1, Day 5
Other	Change in the WHODAS 2.0 score.	The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) will assess for co morbid disabilities. This 12-item survey ranges from 0 to 4 with 0 being "none" and 4 being "extreme or cannot do". Total scores can range from 0 to 48 with higher scores lower levels of social functioning.	Day 1, 3 month
Primary	Change in alpha oscillation power as measured by RSEEG recordings.	Change in alpha oscillation power (8-12 Hz) will be measured between resting state electroencephalogram (RSEEG) recordings.	Day 1, Day 5
Secondary	Change in correlation between the IDAS score and alpha oscillation power (as measured by resting state EEG recordings).	The Inventory of Depression and Anxiety Symptoms (IDAS) Scale is a 10 symptom scale (General depression, Suicidality, Lassitude, Insomnia, Appetite Loss, Appetite Gain, Ill Temper, Well-Being, Panic, Social Anxiety, and Traumatic Intrusions) used to assess depression and anxiety related disorders. The scale ranges from 1 to 5 with 1 equal to "not at all" and 5 equal to"extremely". Higher scores indicate a greater experience of a given symptom.	Day 1, Day 5
Secondary	Change in correlation between the PANAS score and alpha oscillation power (as measured by resting state EEG recordings).	The Positive and Negative Affect Schedule (PANAS) will be used to measure positive and negative emotion. This 20-item self-reported survey will measure 10 positive and 10 negative affective states. Positive affect score ranges from 10-50 and higher scores indicate a greater positive affect. Negative affect scores range from 10-50 with higher scores indicating a greater negative affect.	Day 1, Day 5
Secondary	Change in correlation between the Comparative Pain Scale score and alpha oscillation power (as measured by resting state EEG recordings).	The Comparative Pain Scale score will assess for self-reported pain. The scale ranges from 0 to 10, with 0 equal to "pain free" and 10 equal to "unmanageable, unspeakable". Higher scores reflect a higher severity of self-reported pain.	Day 1, Day 5
Secondary	Change in correlation between the Short Form Health Survey (SF-36) score and alpha oscillation power (as measured by resting state EEG recordings).	The 36-Item Short Form Health Survey (SF-36) measures general health using 36 questions. There are 8 individual health "domains" or categories that each receive their own score, and from these 8 individual scores an overall score can be obtained. Overall scores can range from 0-100, with higher scores indicating better overall health.	Screening, 4 week
Secondary	Change in correlation between the FSMC score and alpha oscillation power (as measured by resting state EEG recordings).	The Fatigue Scale for Motor and Cognitive Functions (FSMC) will measure self-reported levels of physical and mental fatigue. This 20-item survey will measure 10 motor fatigue items and 10 cognitive fatigue items. The scale ranges from 1 to 5 with 1 equal to "does not apply at all" and 5 equal to "applies completely". Total scores can range from 20 to 100 with higher scores indicating worse fatigue.	Day 1, Day 5
Secondary	Change in correlation between the PCS score and alpha oscillation power (as measured by resting state EEG recordings).	The Pain Catastrophizing Scale (PCS) will assess for self-reported pain. The survey consists of 13 items with a 5-point scale, where 0 equals"not at all" and 4 equals "all the time". Total scores can range from 0 to 52 with higher scores indicating a greater frequency in which individuals experience pain-related thoughts and feelings.	Day 1, Day 5
Secondary	Change in correlation between the YMRS score and alpha oscillation power (as measured by resting state EEG recordings).	The Young Mania Rating Scale (YMRS) will assess for manic symptoms at baseline and over the period of the study. The 11 item scale ranges from 0 to 56 with higher scores indicating more severe manic symptoms.	Day 1, Day 5
Secondary	Change in correlation between the HDRS17 score and alpha oscillation power (as measured by resting state EEG recordings).	The Hamilton Depression Rating Scale (HDRS17) will assess for the severity of depressive symptoms in the patients. The scale ranges from 0 to 52 with higher scores indicating a greater severity of depressive symptoms.	Day 1, Day 5
Secondary	Change in correlation between the HAM-A score and alpha oscillation power (as measured by resting state EEG recordings).	The Hamilton Anxiety (HAM-A) scale will assess for the severity of anxiety symptoms. The scale ranges from 0 to 30 with higher scores indicating greater anxiety.	Day 1, Day 5
