QST Study: Predicting Treatment Response in Chronic Pancreatitis Using Quantitative Sensory Testing
Study Overview
Status
Conditions
Detailed Description
In Chronic Pancreatitis (CP), clinical pain symptoms correlate poorly with pancreatic ductal morphology, response to endoscopic or surgical therapy is unpredictable, and the rationale for invasive therapies is often questioned. Quantitative sensory testing (QST) is a technique used to map the pain system based on the rationale that different neural pathways and networks can be explored using standardized stimulation and simultaneous recording of the evoked pain response by psychophysical and/or objective methods. In this study, the investigators aim to distinguish phenotypes characterized by segmental sensitization of the pancreatic viscerotome, and systemic sensitization with pathological central pain processing.
The investigators will perform QST on controls and CP subjects consisting of stimulation in several different dermatomes including pancreatic and control areas. All subjects will also answer standardized questionnaires assessing pain, depression, anxiety, and quality of life at baseline. Subjects undergoing endoscopic or surgical therapy will also undergo follow-up testing consisting of the same tests at 1, 3, and 6 months post-procedure for evaluation of changes in their pain profile.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain Pattern Assessment as assessed by the combination of Temporal Summation score, Sensitization score, and Conditioned Pain Modulation score
Time Frame: One-time baseline testing
|
Assignment to one of four groups (Segmental Sensitization, Systemic Sensitization, Impaired Conditioned Pain Modulation, or Other) based on combination of patient-reported pain symptoms.
Temporal summation pain symptoms are measured on visual analogue scales which are measured from 0 (minimum) to 10 (maximum).
10 on this scale indicates worse pain; 0 indicates no pain.
Sensitization scores are measured via patient reported thresholds in kilopascals.
Conditioned Pain modulation is measured also via patient reported threshold in kilopascals.

One-time baseline testing

Time Frame |
---|---|---|
Change in Mean Pain score
Time Frame: 90 days

In Definite CP Patients undergoing endotherapy as part of regular clinical care, assessment of mean pain level for 7 days prior to endotherapy will be assessed immediately pre-procedure and again at 90 days post-procedure.
A pain reduction of >30% in 90 days after procedure will be characterized as positive response to procedure.
