The Effect of Intravenous Ketamine on Non Suicidal Self Injuries.
- Registration Number
- NCT04242914
- Lead Sponsor
- Tel-Aviv Sourasky Medical Center
- Brief Summary
Non-suicidal self-injuries (NSSI) is a deliberate harm a person causes directly to their body, resulting in structural or functional damage, without suicidal ideation. This behavior is related to unbearable internal stress, thoughts, or mental pain, which NSSI assists in dismantling. To date, there is no generally approved therapy that assists in lowering NSSI. Ketamine is a sedative drug, presently at the focus of psychopharmacologic research, which was found to improve depression, when taken orally, and lower suicidal ideation, when given intravenously. Our aim is to assess the efficiency of intravenous ketamine in decreasing NSSI symptomology in women with a history of childhood sexual abuse presenting with such behavior. Participants will be recruited among hospitalized patients from the Tel-Aviv Medical Central psychiatric ward, who will present with either NSSI urges or behavior. The study design is a randomized control, double blind trial. Each patient will be assessed before, during, and after the trial by physical examination, blood tests and questionnaires. The patients will be randomized into research group (treated by ketamine and midazolam intravenously) or control group (treated intravenously via midazolam only). Our hypothesis is that treatment by intravenous ketamine will lower NSSI symptomology, and enable optimal treatment while being hospitalized.

- PARALLEL
- Arm && Interventions
Group Intervention Description Control: Midazolam Midazolam Control group will receive midazolam. Research: Ketamine + Midazolam Ketamine Research group will receive ketamine and midazolam. Research: Ketamine + Midazolam Midazolam Research group will receive ketamine and midazolam.
- Primary Outcome Measures
Name Time Method Clinical measures - non suicidal self injuries symptoms Four days prior to 1st treatment; after each intervention: 1 hour, 4 hours, 24 hours; next intervention will take place 3 days after (4 interventions altogether); 3 weeks post last intervention. Change in non suicidal self injuries symptoms will be measured by Brief Non-Suicidal Self-Injury Assessment (BNSSI), which assess the quality of self injuries (method of injury, time since last injury, causes of injury, motivation of self injury and bodily areas where injuries are most common).
- Secondary Outcome Measures
Name Time Method Clinical measures - biomarkers related to ketamine treatment - hsCRP Four days prior to 1st treatment; 1 hour after 2nd intervention; 7 days later, 1 hour after 4th intervention; 3 weeks post last intervention. Changes in specific biomarkers as a result of ketamine treatment: high sensitive C-Reactive Protein (hsCRP).
Self reported questionnaires - Suicidal ideation SSI will be taken four days prior to 1st treatment; 1 hour after 2nd intervention; 7 days later, 1 hour after 4th intervention; 3 weeks post last intervention. Changes in suicidal ideation will be measured by Scale for Suicidal Ideation (SSI). Score scale from 0 to 38 points, higher score means increased severity of suicidal ideation.
Self reported questionnaires - impulsivity BIS-11 will be taken four days prior to 1st treatment four days; 3 weeks post last intervention. Changes in impulsive behavior will be measured by Barratt Impulsiveness Scale (BIS-11). This questionnaire assess impulsive behavior, with 30 items, including motor, attention and non-planning contributors. The factors are scored directly and reversibly, hence each factor assessed independently.
Clinical measures - biomarkers related to ketamine treatment - BDNF Four days prior to 1st treatment; 1 hour after 2nd intervention; 7 days later, 1 hour after 4th intervention; 3 weeks post last intervention. Changes in specific biomarkers as a result of ketamine treatment - Brain Dendritic Neurotrophic Factor (BDNF).
Self reported questionnaires - Visual Analogue Scale (VAS) VAS will be after each intervention: 1 hour, 4 hours, 24 hours; next intervention will take place 3 days after (4 interventions altogether). During the treatments, there will be an on going assessment by visual analogue scale, composed of items regarding symptomatology of non suicidal self-injuries, suicidality, Depression and anxiety.
Clinical measures - adverse effects Adverse effects questionnaire will be taken after each intervention: 1 hour, 4 hours; next intervention will take place 3 days after (4 interventions altogether). During the treatments, the patient will be assessed for adverse effects of the infusion by ketamine side effects scale, including physical symptoms and psychotic symptoms.
Clinical measures - biomarkers related to ketamine treatment - IL-6 Four days prior to 1st treatment; 1 hour after 2nd intervention; 7 days later, 1 hour after 4th intervention; 3 weeks post last intervention. Changes in specific biomarkers as a result of ketamine treatment: interleukin 6 (IL-6).
Self reported questionnaires - depressive symptoms BDI will be taken four days prior to 1st treatment; 1 hour after 2nd intervention; 7 days later, 1 hour after 4th intervention; 3 weeks post last intervention. Changes in depressive symptoms will be measured by Back Depression Inventory (BDI). Score scale from 1 to 40 points, higher score means more severe depression.
Self reported questionnaires - anxiety symptoms DASS-21 will be taken four days prior to 1st treatment; 3 weeks post last intervention. Changes in anxiety symptoms will be measured by Depression, Anxiety and Stress Scale (DASS-21 Items).
Score scale from 0 to 63 points, higher score means more severe anxiety symptoms.Self reported questionnaires - well being WHO-5 will be taken four days prior to 1st treatment; 4 hour after 2nd intervention; 7 days later, 4 hour after 4th intervention; 3 weeks post last intervention. Patients well being will be measured by Well-Being Index (WHO 5). Higher score means greater well being.
