Core Tip
Core Tip: In this retrospective study we investigated the clinical, demographic, and microbiologic characteristics of pyogenic liver abscess (PLA) in Mexico. We found that the prevalence of PLA in Mexico is increasing and had a very high mortality rate (63%) in our study. Our data also indicated that the presence of ESBL-Escherichia coli and Klebsiella pneumoniae and an immunocompromised state were independent predictors of high-risk mortality with an adjusted OR of 6.7, 4.8 and 3.9, respectively.
