Extensive gastric mucosal atrophy is a possible predictor of clinical effectiveness of acotiamide in patients with functional dyspepsia
.

BACKGROUND

Acotiamide is known as an effective agent for functional dyspepsia. However, clinical factors related to its effectiveness have not been fully elucidated, so it is difficult to predict the drug's effectiveness prior to its administration in patients.

OBJECTIVE

The present retrospective study was conducted to examine the relationship between clinical factors and the effectiveness of acotiamide for functional dyspepsia.

METHODS

The study subjects were 149 patients with functional dyspepsia who were prescribed acotiamide. Based on medical records and clinical factors, including endoscopic findings, the effectiveness of acotiamide was investigated.

RESULTS

Significant clinical factors associated with acotiamide's effectiveness were identified. These included postprandial syndrome, concomitant mental disorder, and extensive gastric mucosal atrophy. On multiple regression analysis, extensive gastric mucosal atrophy showed the strongest relationship with the clinical effectiveness of acotiamide; the other significant factor was concomitant mental disorder.

CONCLUSIONS

Although the pathophysiology of the relationship between mucosal atrophy and acotiamide remains uncertain, a decrease in hormonal secretion, such as that of ghrelin, may be a possible mechanism. .
