Salsalate as an Adjunctive Treatment for Patients With Schizophrenia
This is a 12-week, open-label trial of salsalate 3 g/day as an adjunctive treatment in 15 schizophrenia subjects to examine salsalate's effect on psychopathology, cognitive functioning, and metabolic parameters.
Potential subjects will be identified by their clinicians at the Freedom Trail Clinic, or Massachusetts General Hospital. A total of 15 subjects will be enrolled.

Detaljerad beskrivning
The specific aims include:
Primary aims:
- Examine the efficacy of salsalate (3g/day) in improving positive and negative symptoms as measured by the Positive and Negative Syndrome Scale (PANSS) and the Scale for Assessment of Negative Symptoms (SANS).
- Examine the efficacy of salsalate in improving cognition as measured by the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) composite score.
Secondary aims:
1. Examine salsalate's effects on inflammatory markers such as high sensitivity C-reactive protein (hs-CRP), TNF-α and IL-6.

Åtgärdsbeskrivning |
Tidsram |
|---|---|---|
|
PANSS Total Score
Tidsram: Baseline and 12 weeks
|
Positive and negative symptoms of schizophrenia will be measured by total score on all subscales of the Positive and Negative Syndrome Scale (PANSS; score range 30-210).
Higher scores correspond with worse outcomes.
|
Baseline and 12 weeks
|
|
SANS Total Score
Tidsram: Baseline, 12 weeks
|
Negative symptoms of schizophrenia will be measured by total score on the Scale for Assessment of Negative Symptoms (SANS; score range 0-100).
Higher scores correspond with worse outcomes.
|
Baseline, 12 weeks
|
|
MATRICS Composite Score
Tidsram: Baseline, 12 weeks
|
Improved cognition will be measured using the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) assessment.
The MATRICS assessment includes a battery of tests, and the composite t-score measures cognition across 7 domains including speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition.
A higher score indicates better cognition.
|
Baseline, 12 weeks
|
|
PANSS Positive Score
Tidsram: Baseline, 12 weeks
|
Subscale of Positive and Negative Syndrome Scale that specifically measures positive symptoms.
The scores range from 7-49, with higher scores representing a worse outcome.
|
Baseline, 12 weeks

|
PANSS- Negative Score
Tidsram: Baseline, 12 weeks
|
Subscale of Positive and Negative Syndrome Scale that specifically measures negative symptoms.
The scores range from 7-49, with higher scores representing a worse outcome.

Åtgärdsbeskrivning |
Tidsram |
|---|---|---|
|
Hs-CRP
Tidsram: Baseline, 12 weeks
|
High-sensitivity C-reactive protein (hs-CRP) will be measured in mg/L in order to detect inflammation.
Higher hs-CRP values correspond to higher levels of inflammation.
|
Baseline, 12 weeks
|
|
TNF-alpha
Tidsram: Baseline,12 weeks
|
Tumor necrosis-alpha factor will be measured to assess inflammation levels.
|
Baseline,12 weeks

|
IL-6
Tidsram: Baseline, week 12
|
IL-6 (interleukin 6) is a marker used to measure inflammation.
