Risk factors and predictors of acute gastrointestinal injury in stroke patients

This prospective study investigates the incidence, risk factors, biological markers, and predictors of acute gastrointestinal injury (AGI) in patients with stroke.

The study involved a total of 98 patients with acute cerebrovascular disease were included. According to the ESICM, the definition of AGI in intensive care patients is classified as grade 0, I, II and III. Patients' demographics, serological indicators (e.g., urea nitrogen, albumin, D-lactate, α-GST, neutrophil count and lymphocyte count), relevant scores (NIHSS score, GCS score, APACHE II score), length of hospital stay as well as the 7-day and 28-day mortality were recorded.

In 98 patients, the incidence of AGI was 90.8 %. The APACHE II, NIHSS, GCS and Hs-mGPS scores significantly increased the odds of a higher AGI grade (P < 0.05). Also, current use of antibiotics and the presence of pneumonia significantly increased the probability of a higher AGI grade (P < 0.05). NLR, diabetes and dehydrating drugs increased the probability of AGI grade II and III (P < 0.05). Finally, an early commencement of endovascular treatment significantly reduced the incidence of AGI class III (P < 0.05). Patients with higher AGI grades had longer hospital stays and higher 28-day mortality (P < 0.05).

The degree of the neurological deficit in stroke patients (high NIHSS score, low GCS score) in this study was associated with the development of AGI. The patients' gastrointestinal barrier function continued to deteriorate during the week of onset. The APACHE II score, NRL score and HS-mGPS score have some predictive value for the occurrence of AGI in stroke patients.
