Gastroparesis Clinical Trial
— PGpR2Official title:
GpCRC Pediatric Gastroparesis Registry 2: Characterization and Clinical Course of Symptoms and Gastric Emptying in Pediatric, Adolescent, and Young Adult Participants With Symptoms of Gastroparesis
The objective of the Pediatric Gastroparesis Registry 2 is to create a national prospective registry of children, adolescents, and young adults with gastroparesis and gastroparesis-like syndrome (symptoms of gastroparesis but normal gastric emptying).

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in mean symptom severity of gastrointestinal symptoms using the change in total score from the Pediatric Quality of Life Inventory (PedsQL) Gastrointestinal Symptoms Scales™ | The PedsQL™ GI Symptoms Scales questionnaire has 65 response items covering 10 dimensions, with each item offered as a better-to-worse 5-point Likert scale choice: 0=never, 1=almost never, 2=sometimes, 3=often, 4=almost always. The item responses are transformed to a worse-to-better order and rescaled to 0-100: 0=almost always, 25= often, 50=sometimes, 75=almost never, 100= never, with higher scores indicating better health-related quality of life (HRQOL) and fewer problems or symptoms.he per-participant PedsQL™ GI Symptoms Scales total score is the sum of the 65 transformed and rescaled item responses. The primary outcome measure is the arithmetic mean of the 65 transformed item responses and is repeated at baseline and 48 weeks for each participant. | Baseline, 48 weeks | |
Secondary | Presence or absence of Carnett's sign as assessed by abdominal examination | Presence or absence Carnett's sign for abdominal wall pain at baseline. Carnett's sign is a finding on clinical examination in which (acute) abdominal pain remains unchanged or increases when the muscles of the abdominal wall are tensed. As part of the abdominal examination, the patient is asked to lift the head and shoulders from the examination table to tense the abdominal muscles. An alternative is to ask the patient to raise both legs with straight knees.
A positive test indicates the increased likelihood that the abdominal wall and not the abdominal cavity is the source of the pain (for example, due to rectus sheath hematoma instead of appendicitis). A negative Carnett's sign is said to occur when the abdominal pain decreases when the patient is asked to lift the head; this points to an intra-abdominal cause of the pain. |
Baseline | |
Secondary | Change in volume (mL) of liquid consumed as assessed by the Water Load Satiety Test | Change from baseline to 48 weeks in amount of liquid (mL) consumed during the Water Load Satiety Test (WLST) Lower volumes are signs of impaired accommodation. | Baseline, 48 weeks | |
Secondary | Change in Pain Catastrophizing Scale scores (PCS) | The outcome is assessed using change in the total score at 48-weeks minus the baseline score. A negative change indicates reduced pain catastrophizing. PCS total score is computed by summing responses to all 13 items. PCS total scores range from 0 - 52. | Baseline, 48 weeks |
