Abstract |
Background |
Early diagnosis and prompt management of acute mesenteric ischaemia (AMI) are key to survival but remain extremely difficult, due to vague and non-specific symptoms. Serum lactate (SL) is commonly presented as a useful biomarker for the diagnosis or prognosis of AMI. The aim of our study was test SL (1) as a diagnostic marker and (2) as a prognostic marker for AMI.
Study design |
This was an ancillary multicentre case-control study. Patients with AMI at intensive care unit (ICU) admission were included (AMI group) and matched to ICU patients without AMI (control group). SL was measured and compared on day 0 (D0) and day 1 (D1). Diagnosis and prognosis accuracy were assessed by receiver operating characteristic (ROC) and their area under the curve (AUC).
Results |
Each group consisted of 137 matched ICU patients. There was no significant difference of SL between the two groups at D0 or at D1 (p = 0.26 and p = 0.29 respectively). SL was a poor marker of AMI: at D0 and D1, AUC were respectively 0.57 [0.51; 0.63] and 0.60 [0.53; 0.67]. SL at D0 and D1 correctly predicted ICU mortality, independently of AMI (AUC D0: 0.69 [0.59; 0.79] vs. 0.74 [0.65; 0.82]; p = 0.51 and D1: 0.74 [0.64; 0.84] vs. 0.76 [0.66; 0.87]; p = 0.77, respectively, for control and AMI groups].
Conclusions |
SL has no specific link with AMI, both for diagnosis and prognosis. SL should not be used for the diagnosis of AMI but, despite its lack of specificity, it may help to assess severity.
