A Phase 1 interventional study of Omeprazole 20mg in Systemic Sclerosis, Gastroesophageal Reflux and Proton Pubm Inhibitor, sponsored by Khon Kaen University. Completed. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2018-06-21.

Proton pump inhibitor (PPI) twice daily dosing regimen-a standard dose therapy for gastroesophageal reflux disease (GERD)-is an effective therapy for uncomplicated GERD in systemic sclerosis (SSc) but there is no data of response rate of standard dose of PPI and predictors of PPI-partial response (PPI-PR) GERD in SSc.Objectives of the study were to determine the prevalence of omeprazole partial response GERD in SSc and to define the predictors of PPI-PR GERD in SSc. Adult SSc patients having GERD were treated with omeprazole 20 mg twice daily 30 minutes before meal for 4 weeks. Severity of symptom-grading by visual analogue scale (VAS) and frequency of symptoms by frequency scale for symptoms of GERD (FSSG) were assessed at baseline and 4 weeks after treatment. PPI-PR GERD was defined by less than 50% improvement in VAS of severity of symptom and acid reflux score by FSSG after treatment compare to baseline.

Changing severity of heart burn of SSc related GERD evaluated by visual analogue score (VAS) Changing Severity of Heart Burn of SSc Evaluated by Visual Analogue Score (VAS)
VAS scale 0-100 was applied for an outcome measurement of the severity of heart burn. The VAS scale 0 was no symptoms of heart burn and scale 100 was a maximum symptom of heart burn. The changing of the severity of heart burn was the changing of VAS before and after treatment. PPI-PR GERD is defined when the changing of severity of heart burn is improvement less than 50% compare to baseline.
Time frame: 4 weeks
Changing of Frequency of Symptoms in SSc related GERD Evaluated by Frequency Scale for the Symptoms of GERD (FSSG)
Unit scale 0-48 was applied for an outcome measurement of the frequency of symptoms. The unit scale 0 was no symptom and scale 48 was usual symptom of GERD. The changing of the frequency of symptoms was the changing of the unit scale before and after treatment. PPI-PR GERD is defined when the changing of frequency of symptom in SSc related GERD evaluated by FSSG is improvement less than 50% compare to baseline.
Time frame: 4 weeks
The proportion of participant with diffuse cutaneous SSc (dcSSc) subset between the patient who response to omeprazole and partial response to omeprazole,
The number of dcSSc subset in the patient who response to omeprazole and partial response to omeprazole, DcSSc is defined as yes or no when the patient has skin tightness includes trunk and both extremities and not include trunk and extremities, respectively.
Time frame: 4 weeks
The proportion of participant with esophageal dysphagia between the patient who response to omeprazole and partial response to omeprazole,
The number of dysphagia in the patients who response to omeprazole and partial response to omeprazole. Esophageal dysphagia is defined as yes or no when the patients has dysphagia and no dysphagia symptom, respectively.
Time frame: 4 weeks
The proportion of participant with female gender between the patient who response to omeprazole and partial response to omeprazole
The number of female gender in the patients who response to omeprazole and partial response to omeprazole. Female gender is defined as yes or no when the patient is female and male, respectively.
Time frame: 4 weeks
The proportion of participant with age>60 years between the patient who response to omeprazole and partial response to omeprazole
The number of age\>60 years in the patients who response to omeprazole and partial response to omeprazole. Age\>60 is defined as yes or no when the patient has age\>60 and equal or less than 60 years, respectively.
Time frame: 4 weeks
The proportion of participant with modified Rodnan skin score (mRSS)>20 between the patient who response to omeprazole and partial response to omeprazole
The number of mRSS\>20 in the patients who response to omeprazole and partial response to omeprazole. The mRSS was assessed at 17 sites; viz., the face, chest, abdomen, arms, forearms, hands, fingers, thighs, legs and feet. Assessment was rated as 0 (normal skin thickness), 1 (mild but definite skin thickness), 2 (moderate thickness), or 3 (sever thickness with inability to pinch a fold of skin). The score was calculated by summing the rating score from all 17 areas (range, 0-51). mRSS\> 20 is defined as yes or no when the patient has mRSS\>20 and equal or less than 20, respectively.
Time frame: 4 weeks
The proportion of participant with serum anti-topoisomerase I antibody positive between the patient who response to omeprazole and partial response to omeprazole
The number of anti-topoisomerase I positive in the patients who response to omeprazole and partial response to omeprazole. Serum anti-topoisomerase I antibody is defined as yes or no when the antibody in serum was positive and negative, respectively.
Time frame: 4 weeks
