Evolution of antibiotic treatments for healthcare-associated infections caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae in France.

BACKGROUND: Infections caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBLE) remain a public health challenge. AIM: We traced the evolution of antibiotics prescribed for patients with ESBLE-healthcare associated infections (ESBLE-HAI) between 2012 and 2017, with a specific focus on treatments for lower urinary tract infections (LUTI). METHODS: We used the 2012 and 2017 French point prevalence survey data. Patients with ESBLE-HAI were defined as those diagnosed with at least one Enterobacteriaceae with ESBL production. Patients with LUTI caused by ESBLE (ESBLE-LUTI) were defined as those with LUTI as the reported infection site and diagnosed with ESBLE. We only analysed treatments intended for HAI. RESULTS: In 2017, more than half of treatments for ESBLE-HAIs were ß-lactams. While from 2012 to 2017 the proportion of carbapenem treatments decreased from 30% to 25%, penicillin treatments doubled. Among patients treated for ESBLE-LUTI, a larger proportion received a single antibiotic in 2017. The most frequently prescribed antibiotics for these infections were amoxicillin/clavulanic acid, nitrofurantoin and ofloxacin. More than one out of six treatments lasted for more than 7 days. Carbapenem use was halved between 2012 and 2017, and decreases were likewise observed for aminoglycosides. CONCLUSION: In accordance with French recommendations, comparison of the two most recent French point prevalence surveys showed an evolution in ESBLE-HAI treatment, especially for ESBLE-LUTI. However, treatment durations remained longer than recommended. Data from the 2022 survey should provide insights on the future evolution of prescription trends.

Association of Healthcare and Aesthetic Procedures with Infections Caused by Nontuberculous Mycobacteria, France, 2012‒2020.

We describe nontuberculous mycobacteria (NTM) infections during 2012-2020 associated with health care and aesthetic procedures in France. We obtained epidemiologic data from the national early warning response system for healtcare-associated infections and data on NTM isolates from the National Reference Center for Mycobacteria. We compared clinical and environmental isolates by using whole-genome sequencing. The 85 original cases were reported after surgery (48, 56%), other invasive procedures (28, 33%) and other procedures (9, 11%). NTM isolates belonged to rapidly growing (73, 86%) and slowly growing (10, 12%) species; in 2 cases, the species was not identified. We performed environmental investigations for 38 (45%) cases; results for 12 (32%) were positive for the same NTM species as for the infection. In 10 cases that had environmental and clinical samples whose genomes were similar, the infection source was probably the water used in the procedures. NTM infections could be preventable by using sterile water in all invasive procedures.

Health crisis: What opportunities for clinical drug research?

The COVID-19 pandemic led to the deployment of an unprecedented academic and industrial research effort, the sometimes redundant nature of which is regrettable, as is the lack of both national and international management. However, it must be noted that during this crisis, regulatory procedures were adapted and certain obstacles in the organisation of clinical research were partly removed to contribute to the deployment of trials as close as possible to patients and to facilitate monitoring and control procedures. The digitisation of certain processes and the decentralisation of certain activities were implemented under the cover of a mobilisation of the authorities and all institutional, academic and industrial players. While in the UK, the optimisation of resources through a single platform trial has made it possible to demonstrate or invalidate the efficacy of many treatments, in France the health crisis has highlighted the fragility of the organisation of clinical research, in particular a lack of coordination and funding, difficulties in implementing studies and a certain reluctance to share data. However, the crisis has also revealed the adaptability of the various stakeholders and has led to the improvement of several processes useful for the deployment of therapeutic innovation. Let us hope that the lessons learned during this crisis will allow for greater efficiency in the event of a new pandemic and, above all, that the progress made will continue to apply to all future clinical research activities.

Health Literacy among Health and Social Care University Students.

Health literacy has been defined by the World Health Organization as the cognitive and social skills which determine the motivation and ability of individuals to gain access to, understand and use information in ways which promote and maintain good health. Its importance in reducing inequalities makes health literacy a thematic area that should be addressed in the training of professionals in the fields of healthcare, Social Work and Education. The objective of this study was to define the health literacy levels of students from the Universities of Girona and Barcelona (Spain) and the Regional Institute of Social Work in Perpignan (France). A cross-sectional study was conducted among students of Nursing, Social Work, Primary Education and Special Education in the 2017-2018 academic year. Sociodemographic and academic variables were considered and the HLS-EU-Q16 questionnaire was used to study health literacy levels. In total, 219 students with an average age of 24.9 participated. Of these, 64.4% were studying Social Work, 23.7% Nursing, 5.9% Primary Education, and 5.9% Special Education. Of the total sample, 36.5% were classified as sufficient in health literacy. The total average score of the health literacy index was 11.1; 13.2 among Nursing students; 10.5 among Social Work students; 10.1 among Primary Education students, and 10.1 among Special Education students (p < 0.001). Nursing students obtained the best results and healthcare was the highest rated subdomain, more than disease prevention and health promotion.

Analysis of OXA-204 carbapenemase-producing Enterobacteriaceae reveals possible endoscopy-associated transmission, France, 2012 to 2014.

OXA-48-like beta-lactamase producing bacteria are now endemic in several European and Mediterranean countries. Among this carbapenemase family, the OXA-48 and OXA-181 variants predominate, whereas other variants such as OXA-204 are rarely reported. Here, we report the molecular epidemiology of a collection of OXA-204-positive enterobacterial isolates (n = 29) recovered in France between October 2012 and May 2014. This study describes the first outbreak of OXA-204-producing Enterobacteriaceae in Europe, involving 12 isolates of an ST90 Escherichia coli clone and nine isolates of an ST147 Klebsiella pneumoniae clone. All isolates co-produced the cephalosporinase CMY-4, and 60% of them co-produced the extended-spectrum beta-lactamase CTX-M-15. The blaOXA-204 gene was located on a 150-kb IncA/C plasmid, isolated from various enterobacterial species in the same patient, indicating a high conjugative ability of this genetic vehicle.

Standard precautions in medical office / Précautions standard et hygiène lors des soins au cabinet médical

Standard precautions in medical office. Standard precautions as the foundation for preventing transmission of infectious agents during patient care in all healthcare settings. Improve hands hygiene, appropriate use of gloves, caps, masks and plastic impermeable aprons must be emphasized. The new respiratory hygiene or cough etiquette concept need to be introduce and applies broadly to all persons who enter a medical office setting, including healthcare personnel, patients and visitors. Diffère de la version française.

Précautions standard et hygiène lors des soins au cabinet médical. Les précautions standard visent à prévenir la survenue d'accidents exposant au sang ou aux liquides biologiques. Son objectif est double : prévenir le risque de transmission d'agents pathogènes du soigné vers le soignant mais aussi du soignant vers le soigné. Elles s'appliquent pour tout patient et en tout lieu de soin. Il était important de rappeler et de synthétiser les mesures d'hygiène des mains, les indications et le choix des différents équipements de protection sans oublier d'introduire la logique d'hygiène respiratoire pour l'exercice en cabinet médical.

Feasibility of azithromycin prophylaxis during a pertussis outbreak among healthcare workers in a university hospital in Paris.

The objective of the present study was to evaluate the feasibility of azithromycin prophylaxis with respect to tolerability and compliance during a pertussis outbreak among healthcare workers in a university hospital ward. Compliance with the prophylaxis regimen was 89%; compliance was 75% from intent-to-treat perspective. The rate of adverse events was 33%. Female sex was associated with reporting of adverse events. Nonstudents and healthcare workers who reported adverse events were less compliant with the prophylaxis regimen.

Circulating endotoxin and antiendotoxin antibodies during severe sepsis and septic shock.

The presence of circulating endotoxin is common during sepsis but its prognostic value is poor. We hypothesized that this lack of correlation with outcome could be related in part to the presence of circulating antiendotoxin antibodies. In a 14-bed medical intensive care unit, in an 821-bed tertiary teaching hospital, we prospectively assessed endotoxin and antiendotoxin antibodies in patients with severe sepsis or septic shock. Blood samples for the determination of circulating endotoxin and antiendotoxin antibodies were drawn when severe sepsis or septic shock were diagnosed (day 0) and then on day 1, day 2, and day 4. Daily measurements of antiendotoxin antibodies did not discriminate survivors from nonsurvivors. No antibody depletion was observed. However, during follow-up, the antiendotoxin immunoglobulin (Ig)M antibody level increased among survivors but decreased among nonsurvivors (51.2 vs -44.8 MU/mL, P=007). Circulating endotoxin was detectable among 9 of 17 patients on inclusion but neither the basal value nor sequential measurements correlated with outcome. These results suggest that during severe sepsis and septic shock, circulating endotoxin is a poor prognostic marker whereas the detection of an increase in IgM antiendotoxin antibody levels could identify survivors. This increase in IgM antibody levels could be attributed to a reactivation of the immune system.

Characterization of CMY-type beta-lactamases in clinical strains of Proteus mirabilis and Klebsiella pneumoniae isolated in four hospitals in the Paris area.

We isolated five clinical strains (three Proteus mirabilis and two Klebsiella pneumoniae) with beta-lactam resistance phenotypes consistent with production of an AmpC-type beta-lactamase. The predicted amino acid sequences of the enzymes were typical of class C beta-lactamases. The enzymes were identified as CMY-2, CMY-4 and a new CMY-variant beta-lactamase, CMY-12. The AmpC beta-lactamases from the two K. pneumoniae isolates were found to be encoded on self-transferable plasmids. The genes encoding the AmpC-type beta-lactamase produced by the three P. mirabilis isolates were chromosomal. Four of the five clinical isolates were from patients transferred from Greece, Algeria and Egypt; one of the K. pneumoniae strains was recovered from a French patient. PFGE analysis and rep-PCR fingerprinting showed that the two P. mirabilis isolates from Greek patients were closely related.
