[Influence of progressive systemic sclerosis on gastric emptying]

Area of Science:

• Gastroenterology
• Rheumatology
• Nuclear Medicine

Context:

• Progressive systemic sclerosis (PSS) is a multisystem autoimmune disease.
• Gastrointestinal dysmotility is a common complication of PSS.
• Accurate assessment of gastric motility is crucial for managing PSS patients.

Purpose:

• To investigate and quantify gastric motility in patients with progressive systemic sclerosis (PSS).
• To compare gastric emptying and transit times between PSS patients and healthy controls.
• To explore potential correlations between gastric motility and disease parameters in PSS.

Summary:

• Gastric motility was assessed using an isotopic method in 26 women with PSS and 12 healthy controls.
• Patients with PSS demonstrated significantly delayed gastric emptying (GE t 1/2: 289 ± 325 min vs. 92 ± 19 min) and prolonged mean transit time (MTT90: 42.3 ± 1.4 min vs. 40 ± 0.9 min) compared to controls (p < 0.001).
• No significant correlation was found between delayed gastric emptying and PSS duration, disease type, or Scl-70 antibody titers.

Impact:

• This study highlights significant gastric dysmotility in PSS patients, underscoring the need for gastrointestinal symptom management.
• The findings provide quantitative data on delayed gastric emptying, aiding in the understanding of PSS pathophysiology.
• The lack of correlation with disease parameters suggests complex mechanisms influencing gastric motility in PSS.
