Design outcomes

Primary

MeasureTime frame
Main Objective: This study aims to evaluate the improvement of dysphagia experienced by patients suffering from systemic sclerosis by pyridostigmine.;Secondary Objective: Secondarily, as esophageal dysmotility results in impaired clearance of refluxate, the influence of pyridostigmine on the severity of symp-toms of gastro-esophageal reflux disease will be assessed.;Primary end point(s): The primary endpoint is the number of patients with improvement of Eckardt score to 3 or less (which is widely accepted as absence of significant dysphagia).;Timepoint(s) of evaluation of this end point: 4 weeks

Secondary

MeasureTime frame
Secondary end point(s): - Changes of Eckardt score from baseline will be compared be-tween both treatment arms; - Changes in HRM (high resolution manometry) parameters from baseline: Increase in Distal Contractility Integral, in-crease in Integrative Relaxatory Pressure 4s, increase in the percentage of successful bolus clearance, decrease in number of failed peristalsis, increase in the percentage of normal peri-stalsis; - Decrease in GERD-FSSG; - Improvement in the score of the SF-36 QOL questionnaire; - Comparison of the occurrence of side effects.;Timepoint(s) of evaluation of this end point: At the end of the study
