OBJECTIVES: The knowledge about pathogens and their antibiotic susceptibility patterns is essential to select an appropriate antibiotic.
METHODS: We investigated the microbiological profile in pancreatic and extrapancreatic infections, and antibiotic sensitivity pattern in patients with acute pancreatitis.
RESULTS: Of 556 patients with acute pancreatitis, only 189 developed bacterial infection; however, bacteremia was present in 42 patients (7.6%). Culture-proven infected pancreatic necrotic collection was present in 161 patients (29%). Escherichia coli and Klebsiella pneumoniae were the most common organisms. Among the bacterial infection cohort, 164 patients developed multidrug-resistant bacterial infection. Infection with multidrug-resistant bacteria, especially at multiple sites, increased mortality. Nearly 50% of patients (n = 94) acquired extremely drug-resistant bacterial infection at some time and emerged as key reason for prolonged hospital and intensive care unit stay. Colistin resistance and tigecycline resistance were documented in 2.1% and 17.2% of the specimens at admission and in 4.6% and 21% of specimens during the hospital stay. Of 556 patients, 102 patients developed fungal infection and 28 patients had only fungal infection without bacterial infection.
CONCLUSIONS: Colistin and tigecycline are best reserved as last-resort antibiotics. Fungal infection was found to be associated with increased mortality, median hospital stay, and intensive care unit stay.
