- To determine the effects of pioglitazone on gastric emptying as measured by the 13C- Spirulina breath test,
- To determine the effects of pioglitazone on satiety as measured by a liquid caloric test
- To determine the effects of pioglitazone on depression and anxiety using the Beck Depression Inventory and State-Trait Anxiety Scores,
- To determine the effects of pioglitazone on Quality of Life using the PAGI-QoL and Short Form (SF)-36 questionnaire,
- To determine the effects of pioglitazone on markers of inflammation (CRP and ESR) and serum cytokine levels
- To determine the nature and incidence of adverse effects from a 12-week course of pioglitazone.
Treatment group

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Severity of gastrointestinal symptoms as assessed by the American Neurogastroenterology and Motility Society Gastroparesis Cardinal Symptom Index Daily Diary
Time Frame: Daily up to 3 months
|
The effect of Pioglitazone on nausea, early satiety, postprandial fullness, and upper abdominal pain as per changes in patient scoring in The American Neurogastroenterology and Motility Society Gastroparesis Cardinal Symptom Index Daily Diary (ANMS GCSI-DD) which has been designed to assess symptoms associated with gastroparesis.
Symptoms are rated as none (0), mild (1), moderate (2), severe (3), very severe (4) scale of the worst severity of the symptom over the last 24 hours.
|
Daily up to 3 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Quality of Life as assessed by the Patient Assessment of Upper Gastrointestinal Disorders-Quality of Life scale
Time Frame: 1 day before treatment and 12 weeks after treatment
|
The effect of Pioglitazone on quality of life assessed by the Patient Assessment of Upper Gastrointestinal Disorders-Quality of Life (PAGI-QoL).
The PAGI-QOL instrument consists of 30 items, each with response options based on a 6-point scale and with a recall period of the previous 2 weeks.
The items are grouped into 5 dimensions: Daily Activities, Clothing, Diet and Food Habits, Relationship and Psychological Well-being and Distress.
A score per dimension as well as a total score can be calculated.
The PAGI-QOL scores range from 0 (lowest QoL) to 5 (highest QoL).
|
1 day before treatment and 12 weeks after treatment
|
Change in Functional status as assessed by the SF-36v2 Health Survey
Time Frame: 1 day before treatment and 12 weeks after treatment
|
The effect of Pioglitazone on quality of life assessed by the SF-36v2 Health Survey.
The SF-36v2 is a 36-item, self-report measure designed to assess quality of life in patients.
This measure also provides two summary scores (physical and mental health) and eight scale scores.
The eight sections are: vitality, physical functioning, bodily pain and general health perceptions, physical role functioning, emotional role functioning, social role functioning and mental health.
Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight.
The lower the score the more disability.
The higher the score the less disability, i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.
|
1 day before treatment and 12 weeks after treatment
|
Change in C- reactive protein level in blood
Time Frame: 1 day before treatment and after 8 weeks of treatment
|
The effect of Pioglitazone on Inflammatory markers as per changes in the values of C reactive protein (CRP) in blood.
Normal CRP levels are below 3.0 mg/L.
|
1 day before treatment and after 8 weeks of treatment
|
Change in Erythrocyte Sedimentation Rate
Time Frame: 1 day before treatment and after 8 weeks of treatment
|
The effect of Pioglitazone on Inflammatory markers as per changes Erythrocyte Sedimentation Rate (ESR) in blood.
Results are reported as the millimeters of clear fluid (plasma) that are present at the top portion of the tube after one hour.
The normal range is 0 to 22 mm/hr for men and 0 to 29 mm/hr for women.
|
1 day before treatment and after 8 weeks of treatment
|
Change in Mood as assessed by the Beck Depression Inventory
Time Frame: 1 day before treatment and 12 weeks after treatment
|
The effect of Pioglitazone on mood as per changes in the score of Beck Depression Inventory (BDI-II).
The BDI-II is a commonly used, reliable 21-item self-report measure designed to assess for depression.
Individuals are asked to respond to each question based on a two-week time period.
The BDI-II is widely used as an indicator of the severity of depression, but not as a diagnostic tool.
BDI-II items are rated on a 4-point scale ranging from 0 to 3 based on the severity of each item.
The maximum total score is 63.
|
1 day before treatment and 12 weeks after treatment
|
Change in Mood as assessed by the State-Trait Anxiety Inventory
Time Frame: 1 day before treatment and 12 weeks after treatment
|
The effect of Pioglitazone on mood as per changes in the score of the State-Trait Anxiety Inventory (STAI).
The STAI is a 40-item self-report measure designed to assess anxiety.
This measure provides two subscale scores (State and Trait).
STAI is one of the first tests to assess both state and trait anxiety separately.
Each type of anxiety has its own scale of 20 different questions that are scored.
Scores range from 20 to 80, with higher scores correlating with greater anxiety.

1 day before treatment and 12 weeks after treatment
|
Change in Behavior as assessed by the Beck Depression Inventory
Time Frame: 1 day before treatment and 12 weeks after treatment
|
The effect of Pioglitazone on behavior as per changes in the score of Beck Depression Inventory (BDI-II).
The BDI-II is a commonly used, reliable 21-item self-report measure designed to assess for depression.
Individuals are asked to respond to each question based on a two-week time period.
The BDI-II is widely used as an indicator of the severity of depression, but not as a diagnostic tool.
BDI-II items are rated on a 4-point scale ranging from 0 to 3 based on the severity of each item.
The maximum total score is 63.
