Eradication of an outbreak of vancomycin-resistant Enterococcus (VRE): the cost of a failure in the systematic screening

BACKGROUND: Vancomycin-resistant enterococci (VRE) are still a concern in hospital units tending to seriously ill patients. However, the cost-effectiveness of active surveillance program to identify asymptomatically VRE colonized patient remains debatable. This work aims at evaluating the cost of a failure in the active surveillance of VRE that had resulted in an outbreak in a French University Hospital. FINDINGS: A VRE outbreak was triggered by a failure in the systematic VRE screening in a medico-surgical ward specialised in liver transplantation as a patient was not tested for VRE. This failure was likely caused by the reduction of healthcare resource. The outbreak involved 13 patients. Colonized patients were grouped in a dedicated part of the infectious diseases unit and tended by a dedicated staff. Transmission was halted within two months after discovery of the index case. The direct cost of the outbreak was assessed as the cost of staffing, disposable materials, hygiene procedures, and surveillance cultures. The loss of income from spare isolation beds was computed by difference with the same period in the preceding year. Payments were drawn from the hospital database. The direct cost of the outbreak (2008 Euros) was €60 524 and the loss of income reached €110 915. CONCLUSIONS: Despite this failure, the rapid eradication of the VRE outbreak was a consequence of the rapid isolation of colonized patient. Yet, eradicating even a limited outbreak requires substantial efforts and resources. This underlines that special attention has to be paid to strictly adhere to active surveillance program

Burden of hepatocellular cancer in patients with type-2 diabetes mellitus: a 2011-2020, french, longitudinal, retrospective, national, cohort study

Background and aims: There are uncertainties on the burden of hepatocellular cancer (HCC) in patients with type-2 diabetes (T2D) in France. We therefore measured national incidences and risks of inhospital HCC. Method: The data source was the 2011–2020 National Hospital Discharge database.We selected all T2D patients. HCC and competing death incidences were measured overall and without well-identified risk factors of liver disease progression, including alcoholic liver disease. Risks were computed with multinomial logistic regression models. Results: The sample comprised 2, 883, 684 adults. Mean (IQR) age was 67 (58, 77) years and 54% were men. HCC incidence (95% CI) was 1.19 (1.17–1.21) per 1000 person-years at risk, totaling 26, 136 (0.9%) cases over 12, 504, 690 patient-years. A history of alcohol use disorders and non-metabolic liver-related risk factors were recorded among 55% and 21% of incident cases, respectively. In patients without well-identified risk factors of liver disease progression, HCC incidence was 0.57 (0.55–0.58) per 1000 person-years at risk. Male sex, age in the 40–70 years category, alcohol use disorders [aOR 20.8 (20.0–21.5)], and obesity [aOR 1.24 (1.2–1.28)] were independently associated with a higher risk of HCC than of competing mortality. Conclusion: A history of alcohol use disorders was the main driver of liver disease progression to HCC in French patients with T2D. Obesity increased the risk of HCC by ∼25%. Patients with T2D should be advised to abstain from alcohol

Epidemiology and Appropriateness of Antibiotic Prescribing in Severe Pneumonia After Lung Resection

International audienceBackground: Postoperative pneumonia (POP) is a severe complication of major lung resection. The objective of this study was to describe the current epidemiology and appropriateness of antibiotic prescriptions in severe POP, 4 years after implementation of an antimicrobial stewardship program that was based on weekly multidisciplinary review of all antibiotic therapies.Methods: This study was a retrospective analysis of a prospectively collected database. It included all cases of severe POP occurring within 30 days after major lung resection of in a 1,500-bed hospital between 2013 and 2015. Criteria for severe POP were acute respiratory failure, severe sepsis, or a rapidly extensive pulmonary infiltrate. The study collected data on incidence, clinical outcomes, and microbiological analyses. Appropriateness of antibiotic prescribing was assessed by quality indicators previously validated in the literature.Results: Over the study period, 1,555 patients underwent major lung surgery. Severe POP occurred in 91 patients (5.8%; confidence interval, 4.7%; 7.0%), with a mortality rate of 9.0% (8 of 91; confidence interval, 3.0%; 14.6%). In POP with positive microbiological results, the proportion of gram-negative bacteria other than Haemophilus was 76% (50 of 66 cases). All patients (91 of 91) had respiratory samples taken within 24 hours after the start of antibiotics; empiric therapy was concordant with the guideline in 80% (69 of 86), and it was switched to pathogen-directed therapy in 74% (46 of 62). In 71 of 91 patients (78%), the antibiotic duration was up to 7 days.Conclusions: This study reported a high proportion of gram-negative bacteria in severe POP. Four years after implementation of the program, quality indicators of antibiotic prescribing were all >70%. The rate of de-escalation to pathogen-directed therapy could be improved, however

Burden of liver disease progression in hospitalized patients with type 2 diabetes mellitus

BACKGROUND AND AIMS: There are uncertainties on the burden of liver disease in patients with type-2 diabetes (T2D). METHODS: We measured adjusted hazard ratios of liver disease progression to hepatocellular cancer and/or decompensated cirrhosis in a 2010-2020 retrospective, bicentric, longitudinal, cohort of 52,066 hospitalized patients with T2D. RESULTS: Mean age was 64±14 years and 58% were men. Alcohol use disorders accounted for 57% of liver-related complications and were associated with all liver-related risk factors. Non-metabolic liver-related risk factors accounted for 37% of the liver burden. T2D control was not associated with liver disease progression. The incidence (95% confidence interval) of liver-related complications and of competing mortality were 3.9 (3.5-4.3) and 27.8 (26.7-28.9) per 1000 person-years at risk, respectively. The cumulative incidence of liver disease progression exceeded the cumulative incidence of competing mortality only in the presence of a well-identified risk factors of liver disease progression, including alcohol use. The incidence of hepatocellular cancer was 0.3 (95% CI, 0.1-0.5) per 1000 person-year in patients with obesity and it increased with age. The adjusted hazard ratios of liver disease progression were 55.7 (40.5-76.6), 3.5 (2.3-5.2), 8.9 (6.9-11.5), and 1.5 (1.1-2.1), for alcoholic liver disease, alcohol use disorders without alcoholic liver disease, non-metabolic liver-related risk factors, and obesity, respectively. The attributable fractions of alcohol use disorders, non-metabolic liver risk-related risk factors, and obesity to the liver burden were 55%, 14%, and 7%, respectively. CONCLUSIONS: In this analysis of data from two hospital-based cohorts of patients with T2D, alcohol use disorders, rather than obesity, contributed to most of the liver burden. These results suggest that patients with T2D should be advised to drink minimal amounts of alcohol. LAY SUMMARY: • There is uncertainty on the burden of liver-related complications in patients with type-2 diabetes • We studied the risks of liver cancer and complications of liver disease in over 50,000 patients with type-2 diabetes • We found that alcohol was the main factor associated with complications of liver disease • This finding has major implications on the alcohol advice given to patients with type-2 diabetes

Burden of grade 3 or 4 liver injury associated with immune checkpoint inhibitors

Background &amp; Aims: There is concern about the burden of liver injury in patients with cancer exposed to immune checkpoints inhibitors (ICIs). Methods: In a retrospective cohort study, we evaluated the likelihood of grade 3/4 liver injury, of grade 3/4 cholestatic liver injury, and of liver failure, as per the Common Terminology Criteria for Adverse Events (CTCAE) version 5, following treatment with ICIs. We compared these occurrences with a group of cancer patients who were propensity-matched and treated with conventional chemotherapy. For all ICI patients experiencing grade 3/4 liver injury, we conducted a causality assessment using the RUCAM method and examined patient outcomes. Results: Among 952 patients (median [IQR] age 66 [57–73] years, 64% males) who were treated with ICI between January 1, 2015, and December 31, 2019, a total of 86 (9%) progressed to grade 3/4 liver injury, and liver failure was not observed. Anti-PD-(L)1/anti-CTLA-4 antibodies combinations (adjusted hazard ratio 3.36 [95% CI: 1.67–6.79]; p <0.001), and chronic hepatitis B (adjusted hazard ratio 5.48 [95% CI: 1.62–18.5]; p = 0.006], were independent risk factors. Liver injury was attributed to ICI treatment in 19 (2.0%) patients. Patients with ICI toxicity typically presented with granulomatous hepatitis or cholangiocyte inflammation. ICI withdrawal was associated with cancer progression and mortality. Re-introduction of ICI was not associated with recurrent grade 3/4 liver injury. Compared with matched patients treated with conventional, non-ICI-based chemotherapy, anti-PD-(L)1/anti-CTLA-4 combinations (p <0.001) and anti-PD-(L)1 monotherapies (p = 0.053) increased the risk of grade 3/4 liver injury and of grade 3/4 cholestatic liver injury, respectively. Conclusions: An increased risk of grade 3/4 liver injury under anti-PD-(L)1/anti-CTLA-4 antibodies was observed, whereas no substantial increase in the likelihood of liver failure occurred even after treatment reintroduction. Impact and implications: There is concern about liver injury in patients with cancer exposed to immune checkpoints inhibitors (ICIs). We investigated the burden of grade 3/4 liver injury after treatment with ICIs in a multicentric cohort of patients with cancer. Overall, a 9% incidence of grade 3/4 liver injury was detected after ICIs, and direct ICI hepatotoxicity was demonstrated in 2% of patients. Anti-PD-(L)1/Anti-CTLA-4 antibody combinations, and chronic HBV infection were independent risk factors. ICI withdrawal for grade 3/4 liver injury was associated with cancer progression. Re-introduction of ICI treatment was not associated with recurrent grade 3/4 liver injury
