Study of Ibuprofen Effects on Brain Function
Study Details
Study Description
Brief Summary
The aim of this project is to determine whether the acute oral administration of Ibuprofen changes the activation pattern in the amygdala and other brain structures during functional magnetic resonance imaging. The investigators use a double-blind, randomized, repeated-measures design. Each of the 20 healthy control subjects will be tested three times and receive placebo, 200 mg or 600 mg dose of ibuprofen p.o. The study will consist of 4 sessions: a baseline screening session and 3 testing sessions scheduled 1-2 weeks apart. Each of these individuals will undergo a multi-level assessment based on the RDoC approach that consists of (a) a standardized diagnostic assessment, (b) self-report questionnaires assessing the positive and negative valence domains as well as interoception, (c) behavioral tasks assessing reward-related processing, avoidance, and aversive processing, cognition, and interoception; (d) physiological measurements consisting of facial emotion expression monitoring, heart rate and respiration, (e) functional magnetic resonance imaging focusing on reward-related processing, fear conditioning and extinction, cognitive inhibition, and interoceptive processing, and (f) biomarker assessments.

Detailed Description
Occasional OTC nonsteroidal anti-inflammatory drugs (NSAID) use is prevalent in the United States (25% aspirin, 9% ibuprofen, and 2% naproxen). An estimated 36 million Americans use over-the-counter (OTC) analgesics daily, however, considering the widespread use of analgesic agents, the overall incidence of serious drug-drug interactions involving these agents has been relatively low. Neuroinflammatory mechanisms have been implicated in depression, and NSAIDs have been found effective in animal models of depression both in monotherapy and when used to augment antidepressant drugs. However, results with NSAIDs have been mixed in human observational studies, with both better and worse depression outcomes reported. In animal studies, mice injected with BCG showed an increase in the total immobility time during the forced swim test (FST) and the tail suspension test (TST) and an increase in cerebral PGE2 and NO levels. Ibuprofen decreased the total immobility time during FST and TST and decreased cerebral PGE2 and NO levels, which was comparable to fluoxetine's effect. This would suggest that ibuprofen might have an antidepressant effect through inhibition of PGE2 and NO production.
Some studies have demonstrated the success of augmentation of antidepressant therapy with nonsteroidal anti-inflammatory drugs (NSAID) in decreasing depressive symptoms. However, little is known about the benefit of NSAID therapy on depressive symptoms. In a recent meta-analysis, using multivariable regression analysis a detectable effect in lowering PHQ-9 score in the ibuprofen or naproxen group (-0.31) and Celebrex group (-0.61) (p= .0390) was observed. However, in a study with cognitively normal volunteers age 70 and older with a family history of Alzheimer-like dementia who were randomly assigned to receive celecoxib 200 mg twice daily, naproxen sodium 220 mg twice daily, or placebo the investigators found no treatment effect on geriatric depression scores over time in the subgroup of participants with significant depressive symptoms at baseline. Moreover, there is some concern that anti-inflammatory drugs inhibit the antidepressant effects of SSRIs. In the only published fMRI study, ten healthy subjects underwent a double-blind, placebo-controlled, randomized, cross-over phFMRI study with somatosensory painful stimulation of the right median nerve. These authors reported a task-related increase of BOLD signal between drug and placebo in the primary somatosensory area and the middle frontal gyrus that was not related to changes in subjective pain scores. Thus there is some evidence that ibuprofen influences the BOLD response in specific pain-related brain areas. Taken together, there is mixed evidence for the effect of ibuprofen on mood and no data on its effect on the emotion circuitry.
Hypotheses:
-
The activation pattern in the amygdala during risk-taking decision-making will be attenuated by ibuprofen in a dose dependent manner.
-
The activation pattern in the amygdala during anticipatory emotional arousal will be attenuated by ibuprofen in a dose dependent manner.
-
The activation pattern in the amygdala during emotional face processing will be attenuated by ibuprofen in a dose dependent manner.
-
The behavioral response during tasks assessing emotional and cognitive processes including positive and negative valence and reward based learning will be modulated by ibuprofen in a dose dependent manner.

Comments | A linear mixed effects model was run for the left amygdala with contrast and percent signal change between faces and shapes as the dependent variable and ibuprofen dose as a continuous predictor. Each subject had up to 3 visits and each visit contained 3 contrasts (happy - shape, angry - shape, fearful - shape) so subject and drug were used as random effects. Drug was nested inside of subject. | |
