Pancreatic Quantitative Sensory Testing (P-QST)

Sponsor: Children's Hospital Medical Center, Cincinnati

View on ClinicalTrials.gov

Summary

Quantitative Sensory Testing (QST) is a novel investigative technique used in other pain conditions to evaluate patterns of chronic pain, and in this study will be used to elucidate pain patterns in patients with Chronic Pancreatitis (CP). QST uses a specific series of standardized stimulations to map the pain system. QST has the potential to change and improve the treatment paradigm for patients with CP and may eventually be able to predict response to invasive CP therapies.

Interventions

DIAGNOSTIC_TEST

Quantitative Sensory Test 1

Subject will give pain rating (on Visual Analogue Scale (VAS) 0-10) of single as well as multiple stimulation with round-tip non-invasive pin-prick device. Difference is recorded as Temporal Summation Score.

DIAGNOSTIC_TEST

Quantitative Sensory Test 2

Subject will state when they first detect pain and pain detection threshold in response to pressure administration with pressure algometer. Pressure threshold recorded in kilopascals(kP). Stimulation will be repeated in pancreatic and control dermatomes. Subject will then state pain tolerance threshold at same locations. Sensitization will be characterized by ratio of pancreatic vs. control dermatome scores.

DIAGNOSTIC_TEST

Quantitative Sensory Test 3

Subject will apply dominant hand to ice-chilled water bath (36F) for up to 2 minutes. Pain score (VAS 0-10) will be assessed each 10 seconds. Pain tolerance threshold (in kP) will be assessed with algometer on non-dominant thigh before and after water bath to determine change in threshold. Difference in pain tolerance recorded as Conditioned Pain Modulation Score.
