Introduction: Control attenuation parameters (CAP) can detect nonalcoholic fatty liver disease (NAFLD). Our previous study found that miR-192-5p could screen for acute pancreatitis (AP) in NAFLD patients. This study focused on the role of CAP and miR-192-5p in NAFLD of acute AP.
Material and methods: AP patients and controls were enrolled. Classification of AP patients into NAFLD/AP patients and non-NAFLD/AP was made based on the CAP value. CAP was measured by liver transient elastography. Serum miR-192-5p was measured by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Logistic regression analysis was conducted to examine the risk factors for the development of NAFLD. Receiver operating characteristic (ROC) was assessed for the predictive value of AP severity.
Results: NAFLD was more common in the AP group than in the controls (35.00% vs. 8.75%). The CAP value was higher in AP patients with NAFLD than in non-NAFLD, whereas miR-192-5p was significantly lower in AP patients with NAFLD. Additionally, AP patients with NALFD are more likely to experience respiratory failure, systemic inflammatory response syndrome (SIRS), and pancreatic necrosis with longer hospitalisation and exacerbate the incidence of moderate to severe AP. Both miR-192-5p and TG are potential risk factors for the development of NAFLD in patients with AP. Furthermore, the CAP value gradually increased with increasing AP severity, while miR-192-5p gradually decreased. Finally, the sensitivity and specificity of CAP combined with miR-192-5p for the prediction of moderate to severe AP were scored as 82.61% and 82.43%, respectively.
Conclusions: NAFLD exacerbated the progression of AP, and CAP combined with miR-192-5p could predict the severity of AP. Our study may provide more reference for AP disease progression and treatment.
