Objectives: To describe the prevalence and nature of bacterial co-infections in COVID-19 patients within 48 hours of hospital admission and assess the appropriateness of empirical antibiotic treatment they received.

Methods: In this retrospective observational cohort study, we included all adult non-pregnant patients who were admitted to two acute hospitals in North West London in March and April 2020 and confirmed to have COVID-19 infection within 2 days of admission. Results of microbiological specimens taken within 48 hours of admission were reviewed and their clinical significance was assessed. Empirical antibiotic treatment of representative patients was reviewed. Patient age, gender, co-morbidities, inflammatory markers at admission, admission to ICU and 30 day all-cause in-hospital mortality were collected and compared between patients with and without bacterial co-infections.

Results: Of the 1396 COVID-19 patients included, 37 patients (2.7%) had clinically important bacterial co-infection within 48 hours of admission. The majority of patients (36/37 in those with co-infection and 98/100 in selected patients without co-infection) received empirical antibiotic treatment. There was no significant difference in age, gender, pre-existing illnesses, ICU admission or 30 day all-cause mortality in those with and without bacterial co-infection. However, white cell count, neutrophil count and CRP on admission were significantly higher in patients with bacterial co-infections.

Conclusions: We found that bacterial co-infection was infrequent in hospitalized COVID-19 patients within 48 hours of admission. These results suggest that empirical antimicrobial treatment may not be necessary in all patients presenting with COVID-19 infection, although the decision could be guided by high inflammatory markers.

Temocillin use in England: clinical and microbiological efficacies in infections caused by extended-spectrum and/or derepressed AmpC β-lactamase-producing Enterobacteriaceae.

J Antimicrob Chemother 2011 Nov 2;66(11):2628-31. Epub 2011 Aug 2.

Royal Free Hampstead NHS Trust, London, UK.

Background: Temocillin, a β-lactam stable against most β-lactamases [including extended-spectrum β-lactamases (ESBLs) and derepressed AmpC cephalosporinases (dAmpC)], has been suggested as an alternative to carbapenems when Pseudomonas can be excluded. Aims To assess temocillin clinical and microbiological cure rates (CCR and MCR) in infection caused by ESBL/dAmpC-producing Enterobacteriaceae and the effects of different dosage regimens.

Methods: Data were collected retrospectively from patients treated for at least 3 days with temocillin for urinary tract infection (n = 42), bloodstream infection (n = 42) or hospital-acquired pneumonia (n = 8) in six centres in the UK.

Results: Data on 92 infection episodes were collected. Overall CCR and MCR were 86% and 84% respectively; ESBL/dAmpC status had no effect. Significantly higher CCR and MCR occurred in patients treated with temocillin at optimal dosage [2 g twice daily or renally adjusted equivalent (ORAE)] compared with those treated with a suboptimal dosage (<2 g twice daily ORAE) (CCR 91% and MCR 92% versus CCR 73% and MCR 63%). This difference was more pronounced in the ESBL/dAmpC-positive subset (CCR 97% and MCR 97% versus CCR 67% and MCR 50%).

Conclusions: Clinical and microbiological efficacies of temocillin are unaffected by ESBL/dAmpC production, confirming its potential application as a carbapenem-sparing agent. Both CCR and MCR are optimized by a regimen of 2 g twice daily ORAE in ESBL/dAmpC-positive infection.
