Intervention / Treatment
Detailed Description
Less than half of patients with major depressive disorder (MDD) remit after first-line therapy (i.e., pharmacotherapy and/or psychotherapy). A progressively smaller proportion of patients remit with each subsequent medication trial, and a remission rate of only 10-15% after a fourth antidepressant trial. Patients with MDD are considered to have a treatment-resistant depression (TRD) whey they do not achieve response to first-line antidepressants. Repetitive Transcranial Magnetic Stimulation (rTMS) applied over the DLPFC for modulating brain activity and network connectivity has well-documented positive effects on major depressive disorder (MDD), especially TRD. rTMS research in treating MDD has shown a dose-response relationship and more recently, studies have shown a trend towards administering more stimuli over a shorter period of time and at higher frequencies leading to accelerated protocols. An optimized rTMS parameter called intermittent theta burst stimulation (iTBS) is a novel protocol that consists of intermittently delivering bursts of 3 TMS pulses at high frequency (50 Hz) every 200 ms for 2 s (5Hz) every 10 s (total 600 pulses), allowing for greater long-lasting effects on cortical excitability and a more important number of rTMS pulses to be delivered in a shorter duration than standardized high frequency (HF) rTMS protocols. iTBS induces a long-term potentiation (LTP)-like effect by increasing the postsynaptic concentration of calcium ions and has been applied to treat MDD. iTBS has been proved to be safe and well tolerated and to have antidepressant properties. Prolonged iTBS (piTBS, total 1800 pulses) has been recently applied to treat MDD with favorable antidepressant properties. An accelerated protocol of piTBS has been recently approved to treat medication-refractory MDD by FDA.
MDD is associated with a 2.3 fold increase in prevalence of suicidal ideation as compared to the general population. The lifetime rate of death due to suicide among MDD patients is 15-20%. Research indicates that 30% of TRD patients will attempt suicide during their lifetime, which is a two-to-four times greater proportion than MDD patients who respond to treatment. Research indicates that rTMS improves several preconditions for suicide, including mood, memory, attention, executive functioning. rTMS is thought to have molecular effects similar to those seen with electroconvulsive therapy (ECT), which is effective in treating suicidal patients, such as increased BDNF, increased monoamine turnover and normalization of the hypothalamic-pituitary-adrenal axis. Some research indicates that rTMS may reduce suicidal ideations of patients with MDD. However, powered sham-controlled rTMS clinical trials focusing on the efficacy to improve suicide risks are limited.
Our study aims to investigate the efficacy of accelerated piTBS over the left DLPFC as an add-on therapy to improve suicide ideations in TRD patients. Moreover, it provides data on other secondary outcomes and neurophysiological data for this intervention condition.

Intervention / Treatment |
---|---|
Experimental: piTBS (active, N=50)
The piTBS sessions will be delivered using the Magstim Rapid2 stimulator (Magstim Company, Ltd, Whitland, Wales, UK, SA340HR) with a 70-mm air-cooled figure-eight coil (Magstim D70 Air film coil).
The piTBS protocol consists of 3-pulse 50-Hz bursts given every 200 ms (at 5 Hz) for 2 s at 8-s intervals for 60 cycles.
A 2-s train of piTBS will be repeated every 10 s for a total of 1800 pulses per session.
The intensity of stimulation will be set at 90% resting motor threshold (RMT), as measured from the right first dorsal interosseous muscle by a handheld 700-mm figure-of-eight coil (Magstim D70 alpha coil).
The Beam F3 method will be used for coil positioning to target the left dorsolateral prefrontal cortex.
The piTBS protocol will be scheduled for 3 sessions per working day for 2 weeks (i.e., a total of 30 sessions over 2 weeks).
Three sessions of the piTBS per day will be separated by at least 60 mins.

|
The changes over time in the results of indices of heart rate variability (HRV) (from baseline to the timepoint at the end of piTBS) and the HRV indices during each piTBS session.
Time Frame: 2 weeks
|
HRV indices represent autonomic functioning.
ECG electrodes were placed on bilateral arms just below the elbows, with a ground electrode placed just above the right wrist bone.
For HRV indices measured at baseline and the end of piTBS, lead I electrocardiogram of each patient was taken for 5 min after sitting and having a rest for 20 min in a soundproof, dim-lighted room with thermostatic control.
For HRV indices measured during each piTBS session, lead I electrocardiogram of each patient was taken for 11 min.
The ECG signals were acquired, stored, pre-processed according to the recommended procedures and processed by an HRV analyser.
The time domain of HRV is obtained: Standard deviation of NN intervals (SDNN).
Power spectrum of HRV is quantified into the standard frequency-domain measurements including low-frequency power (LF, 0.04-0.15
Hz), high-frequency power (HF, 0.15- 0.40 Hz).

2 weeks
|
The changes over time in EEG absolute power and lag phase synchronization in the frontal electrodes in the delta, theta, alpha, beta and gamma range (from baseline to the end of piTBS).
Time Frame: 2 weeks
|
In a recliner in a dimly lit, electrically shielded room, patients' EEGs were recorded at baseline and at the end of piTBS by using the full-band DC-EEG system with 32 EEG Ag/AgCl electrodes in the extended 10-20 International placement.
EEG will be collected with eye opened (5min) and closed (5min).
Signals will be amplified in the dynamic input range of ± 140 mV at a resolution of 0.5 μV by using EEG amplifiers and stored for offline analyses.
Eye or muscle artifacts were automatically detected and removed.
|
2 weeks
|
The changes over time in high density near infrared spectroscopy (from baseline to the end of piTBS).
Time Frame: 2 weeks
|
Resting-state and cognitive-task protocol used for the functional near infrared spectroscopy (fNIRS) system to measure the relative changes in oxy Hb.
Hemoglobin Hb changes will be measured during a resting state (for 3 min) and 2 different cognitive tasks (each for around 5 min): semantic verbal fluency task (SVFT) and a 2 back task.
An SVFT involves generating as many words as possible within a certain time frame and hints at the semantic category of the words generated.
The 2 back task is used to evaluate participants' working memory.
