Trial Outcomes & Findings for Effects of Pioglitazone on Stress Reactivity and Alcohol Craving (Pilot) (NCT NCT03860753)

NCT ID: NCT03860753

Last Updated: 2020-10-26

Results Overview

The cold pressor task (CPT) a stress-inducer in human laboratory studies that elicits moderate activation of the sympathetic nervous system and limited activation of the HPA-axis. During CPT, participants will submerge their dominant arm in an ice-water bath for up to 2 minutes, and heart rate will be measured before and after CPT. The heart rate change for each time point is calculated as heart rate after CPT minus the heart rate before CPT. This outcome measure reports the heart rate change at week 4 minus the heart rate change at baseline.

PRIMARY outcome

Timeframe: baseline, week 4

Population: All 4 participants were allocated to Pioglitazone and none to placebo.

The cold pressor task (CPT) a stress-inducer in human laboratory studies that elicits moderate activation of the sympathetic nervous system and limited activation of the HPA-axis. During CPT, participants will submerge their dominant arm in an ice-water bath for up to 2 minutes, and heart rate will be measured before and after CPT. The heart rate change for each time point is calculated as heart rate after CPT minus the heart rate before CPT. This outcome measure reports the heart rate change at week 4 minus the heart rate change at baseline.

The cold pressor task (CPT) a stress-inducer in human laboratory studies that elicits moderate activation of the sympathetic nervous system and limited activation of the HPA-axis. During CPT, participants will submerge their dominant arm in an ice-water bath for up to 2 minutes, and blood pressure will be measured before and after CPT. The blood pressure change for each time point is calculated as blood pressure after CPT minus the blood pressure before CPT. This outcome measure reports the blood pressure change at week 4 minus the blood pressure change at baseline.

The cold pressor task (CPT) a stress-inducer in human laboratory studies that elicits moderate activation of the sympathetic nervous system and limited activation of the HPA-axis. During CPT, participants will submerge their dominant arm in an ice-water bath for up to 2 minutes, and salivary cortisol level will be measured before and after CPT. The salivary cortisol level change for each time point is calculated as salivary cortisol level after CPT minus the salivary cortisol level before CPT. This outcome measure reports the salivary cortisol level change at week 4 minus the salivary cortisol level change at baseline.

The Penn Alcohol Craving Scale (PACS) is a 5-item questionnaire that measures an individual's craving to drink alcohol in the past week. Each item is scored on a scale from 0 to 6, with a total score range of 0 to 30. A higher score indicates greater level of alcohol craving.
