Introduction. In 2019, the European Committee for the Study of Antibiotic Susceptibility modified the categories of antibiotic susceptibility tests to include the term “susceptible with increased exposure”. Following the dissemination of local protocols reflecting these modifications, the aim of our study was to analyse whether prescribers have adapted to them and the clinical impact in cases of inadequacy.
Material and methods. Observational and retrospective study of patients with infection who received antipseudomonal antibiotics from January to October 2021 in a tertiary hospital.
Results. Non-adherence to the guideline recommendations was 57.6% in the ward and 40.4% in the ICU (p<0.05). In both the ward and ICU, the group with the most prescriptions not by the guideline recommendations were aminoglycosides (92.9% and 64.9% respectively) for using suboptimal doses, followed by carbapenems (89.1% and 53.7% respectively) for not administering an extended infusion. On the ward, the mortality rate during admission or at 30 days in the inadequate therapy group was 23.3% vs 11.5% in those who received adequate treatment (OR: 2.34; 95% CI 1.14-4.82); in ICU there were no statistically significant differences.
Conclusions. The results show the need to implement measures to ensure better dissemination and knowledge of key concepts in antibiotic management, to ensure increased exposures, and to be able to provide better infection coverage, as well as to avoid amplifying resistant strains.

Role of Hologic® Panther AptimaTM SARS-CoV-2 assay in the detection of SARS-CoV-2: screening or diagnostic technique?

During the multiple waves of COVID-19 suffered all over the world, having a rapid and sensitive diagnostic test has become a priority for microbiology laboratories. The AptimaTM SARS-CoV-2 transcription-mediated amplification (TMA) assay running on the Panther system (Hologic) was presented as a very good option to cover this need. To evaluate this system, 570 respiratory samples were included in the study and were processed both by the Panther (Hologic) system and by qRT-PCR (Thermo Fisher Science, Waltham, USA), current assay for the diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A high number of false positives (n=76) was obtained with Panther system (Hologic), but the number of false positives decreases as the relative light units (RLU) value increases. These results show that this technique can be a good option for sample screening but checking for positive results should be mandatory, especially those with low RLU values.

Tuberculous otitis media: A case presentation and review of european literature

Tuberculous otitis media (TOM) is a rare affectation in our environment that represents a challenge in its diagnosis due to the non-specific symptoms that it usually presents. This paper presents our experience in the diagnosis of a case of TOM in a 66-year-old woman with hearing loss and chronic otorrhea of more than 6 months of evolution that did not respond to conventional treatments. In addition, a review of the cases published in the last 20 years (2000-2022) in countries of the European Union (EU) is carried out. The most common symptoms were otorrhea (n=43; 100%), hearing loss (n=37; 86.05%), eardrum perforation (n=19; 44.18%), facial paralysis (n=12, 27,91%) and ear pain (n=13; 30,23%). The most used sample for diagnosis was the biopsy obtained by mastoidectomy (n=34; 79.06%). All patients were given antituberculous therapy for a mean duration of 8.11 months (range, 6-12 months). The most frequent aftereffect was hearing loss (n=28; 65.12%). TOM should be included in the differential diagnosis of chronic suppurative otitis, since early diagnosis and treatment reduce the probability of suffering irreversible sequelae.

Objective. We aim to evaluate the adherence rate to an Antimicrobial Stewardship Program (ASP) in an Intensive Care Unit (ICU), and to assess its effect on the use of antibiotics, quality indicators and clinical outcomes.
Patients and methods. Retrospective description of the interventions proposed by the ASP. We compared antimicrobial use, quality and safety indicators in an ASP versus a non-ASP period. The study was performed in a polyvalent ICU of a medium-size University Hospital (600 beds). We studied patients admitted to the ICU for any cause during the ASP period, provided that a microbiological sample aiming to diagnose a potential infection has been drawn, or antibiotics have been started. We elaborated and registered of non-mandatory recommendations to improve antimicrobial prescription (audit and feedback structure) and its registry during the ASP period (15 months, October 2018-December 2019). We compared indicators in a period with ASP (April-June 2019) and without ASP (April-June 2018).
Results. We issued 241 recommendations on 117 patients, 67% of them classified as de-escalation type. The rate of adherence to the recommendations was high (96.3%). In the ASP period, the mean number of antibiotics per patient (3.3±4.1 vs 2.4±1.7, p=0.04) and the days of treatment (155 DOT/100 PD vs 94 DOT/100 PD, p <0.01) were reduced. The implementation of the ASP did not compromise patient safety or produce changes in clinical outcomes.
Conclusion. The implementation of an ASP is widely accepted in the ICU, reducing the consumption of antimicrobials, without compromising patient safety.
