简要总结
The purpose of this 10-week, double-blind, placebo-controlled study is to determine whether inflammation impacts reward and motor neural circuitry to contribute to depressive symptoms like anhedonia and psychomotor slowing in people with Human Immunodeficiency Virus (HIV) and depression. Sixty male and female patients with HIV who have depression, anhedonia and high inflammation and are stable on effective treatment for their HIV will be randomized to receive either the anti-inflammatory drug baricitinib or a placebo for 10 weeks. Participants will complete lab tests, medical and psychiatric assessments, neurocognitive testing, functional MRI (fMRI) scans, and optional spinal taps as part of the study.
详细描述
Risk of depression is substantially higher in people with HIV (PWH) than the general population, and depression in PWH confers worse outcomes regarding treatment adherence, morbidity, and mortality. Increased inflammation is one biological pathway that is linked to greater risk for depression in PWH and limits options for effective antidepressant therapy. Chronically elevated inflammation is associated with impairments within reward and motor neural circuits that contribute to symptoms of anhedonia (an inability to experience pleasure) and psychomotor slowing, which are overrepresented in PWH. The purpose of this 10-week, double-blind, placebo-controlled study is to provide mechanistic information on whether inflammation impacts corticostriatal reward and motor circuitry to contribute to anhedonia and psychomotor slowing in PWH with depression using the anti-inflammatory drug baricitinib.
This study will utilize an FDA-approved medication, baricitinib, to establish whether the effects of inflammation on reward and motor circuits are a mechanism of anhedonia and motor slowing in PWH with depression, while advancing avenues for new therapies.

结局指标
主要结局
Change in corticostriatal functional connectivity (FC) in reward circuit
时间窗: Baseline visit, week 2, and week 10 after study medication
Patients will undergo resting-state and task-based functional magnetic resonance imaging (fMRI) to calculate functional connectivity (FC) between the ventral striatum (VS) and ventromedial prefrontal cortex (vmPFC). FC is measured as continuous Z scores reflecting the correlation of activity between the brain regions. Higher FC Z scores reflect stronger connectivity.
