RESUMO
INTRODUCTION: Respiratory syncytial virus (RSV) causes an acute respiratory illness similar to influenza, although there are few data comparing both of them in adults. The existence of clinical differences between these two infections could have implications for their management. MATERIALS AND METHODS: Retrospective observational cohort study including 63 adults with positive PCR for RSV and 221 for influenza during winter 2018-2019. Epidemiological, clinical characteristics and outcomes were contrasted between both groups. RESULTS: Compared to influenza, RSV-positive patients presented a higher association with active neoplasia (OR=2.9; 95% CI: 1.2-6.9), dependence for basic activities of daily living (OR=3.4; 95% CI: 1.4-8.2) and immunosuppression due to chronic glucocorticoid administration (OR=7.6; 95% CI: 1.6-36.1). At diagnosis, fever was less common (OR=0.3; 95% CI: 0.2-0.7), and C-reactive protein level ≥100mg/l was more frequent (OR=2.1; 95% CI: 1.0-4.5). They developed bacterial co-infection by Staphylococcus aureus in a higher proportion (OR=8.3; 95% CI: 1.5-46.9) and presented a greater need for admission to the intensive care unit (OR=5.4; 95% CI: 1.4-19.2). CONCLUSION: RSV is an important cause of respiratory illness in adults during the influenza season. It especially affects vulnerable patients with chronic underlying diseases, and has a higher morbidity than influenza. For all these reasons, specific detection, prevention and treatment of RSV is necessary in order to reduce the consumption of health care resources due to RSV disease in adults.

BACKGROUND: Both fidaxomicin and bezlotoxumab (used in combination with an antibiotic against Clostridioides difficile) achieve reductions in recurrence rates of C. difficile infection (CDI). However, the two strategies have never been compared. METHODS: Data from two retrospective cohorts of 'real-life' use of fidaxomicin and bezlotoxumab in combination with a standard anti-C. difficile antibiotic were used to compare the rates of recurrence of both strategies. Since the two cohorts were not identical, we used a propensity score analysis. RESULTS: Three hundred and two patients were included: 244 in the fidaxomicin cohort and 78 in the bezlotoxumab cohort. A history of renal failure or immunosuppression was more frequent in patients receiving bezlotoxumab (39.7% and 66.7% versus 26.6% and 38.9%; Pâ=â0.03 and Pâ<â0.001, respectively), but the severity and number of previous CDI episodes were similar in both cohorts. We observed that 19.3% of the patients in the fidaxomicin cohort experienced recurrence, compared with 14.1% in the bezlotoxumab cohort (OR 1.45; 95% CI 0.71-2.96; Pâ=â0.29) but the difference remained non-significant after propensity score matching using previously defined variables (OR 1.24; 95% CI 0.50-3.07; Pâ=â0.64). Moreover, the multivariate analysis did not show differences depending on the drug used. CONCLUSIONS: We observed that fidaxomicin and bezlotoxumab are prescribed in similar clinical scenarios, although those treated with bezlotoxumab have greater comorbidity. The proportion of recurrences was numerically lower in those treated with bezlotoxumab, although the propensity analysis did not find significant differences between the two drugs.

OBJECTIVE: To describe the clinical experience with dalbavancin in the treatment of diabetic foot infection in a multidisciplinary unit of a second level hospital. METHODS: A retrospective, descriptive study was made with all patients with diabetic foot infection treated with dalbavancin in the Diabetic Foot Unit of Hospital Universitario Fundación Alcorcón, covering the period from September 2016 to December 2019. Demographic parameters and comorbidities, characteristics of the infection and treatment with dalbavancin were recorded. The cure rate is estimated at 90 days after finishing the treatment. RESULTS: A total of 23 patients with diabetic foot infection (osteomyelitis) started treatment with dalbavancin, 19 were men and the mean age was 65 years. The microorganisms most frequently isolated for the indication of treatment with dalbavancin were Staphylococcus aureus (11) and Corynebacterium striatum (7). Dalbavancin was used as a second choice therapy in 22 cases, in 11 due to toxicity from other antibiotics. The median duration of treatment was 5 (4-7) weeks; the most frequent dose of dalbavancin (8 patients) was 1000â¯mg followed by 500â¯mg weekly for 5 weeks. 3 patients presented mild side effects (nausea and gastrointestinal discomfort). At 90 days after completion of dalbavancin therapy, 87% (20) of the patients were cured (95% CI: 65.2%-94.52%). CONCLUSION: Patients with osteomyelitis due to gram-positive microorganisms who received as part of the multidisciplinary antibiotic treatment with dalbavancin, had a high rate of cure with adequate tolerance and few side effects. Dalbavancin offers a safe alternative in treating deep diabetic foot infection.

RESUMO
Bezlotoxumab is marketed for the prevention of recurrent Clostridioides difficile infection (rCDI). Its high cost could be determining its prescription to a different population than that represented in clinical trials. The objective of the study was to verify the effectiveness and safety of bezlotoxumab in preventing rCDI and to investigate factors related to bezlotoxumab failure in the real world. A retrospective, multicentre cohort study of patients treated with bezlotoxumab in Spain was conducted. We compared the characteristics of cohort patients with those of patients treated with bezlotoxumab in the pivotal MODIFY trials. We assessed recurrence rates 12 weeks after completion of treatment against C. difficile, and we analysed the factors associated with bezlotoxumab failure. Ninety-one patients were included in the study. The cohort presented with more risk factors for rCDI than the patients included in the MODIFY trials. Thirteen (14.2%) developed rCDI at 12 weeks of follow-up, and rCDI rates were numerically higher in patients with two or more previous episodes (25%) than in those who had fewer than two previous episodes of C. difficile infection (CDI) (10.4%); p = 0.09. There were no adverse effects attributable to bezlotoxumab. Despite being used in a more compromised population than that represented in clinical trials, we confirm the effectiveness of bezlotoxumab for the prevention of rCDI.
RESUMO
Emphysematous pyelonephritis (EPN) is a rare and serious necrotizing infection that is potentially life-threatening. It has been seldom reported in kidney grafts and is usually caused by Gram-negative bacteria, with some case reports caused by anaerobic bacteria, and has been closely associated with poorly controlled diabetes mellitus (DM) and urinary tract structural abnormalities. There are no reports of EPN of fungal etiology in kidney grafts. We present a case of a 53-year-old kidney transplant recipient with a history of DM, active vesicoureteral reflux, and recurrent urinary tract infections who developed EPN in the kidney allograft caused by Candida glabrata, 3 weeks after starting treatment with empagliflozin, with an aggressive course that required urgent transplant nephrectomy.

BACKGROUND: Interstitial lung disease (ILD) is a frequent manifestation of Sjögren's syndrome (SS), an autoimmune disease of salivary and lacrimal glands, and affects approximately 20% of patients. No clinical or serological features appear to be useful to predict its presence, severity or progression, and chest high-resolution computed tomography (CT) remains the gold standard for diagnosis. Semiquantitative CT (SQCT) based on visual assessment (Goh and Taouli scoring) can estimate ILD extent, although it is burdened by relevant intra- and interobserver variability. Quantitative chest CT (QCT) is a promising alternative modality to assess ILD severity. AIM: To determine whether QCT assessment can identify extensive or limited lung disease in patients with SS and ILD. METHODS: This multi-center, cross-sectional and retrospective study enrolled patients with SS and a chest CT scan. SQCT assessment was carried out in a blinded and centralized manner to calculate both Goh and Taouli scores. An operator-independent analysis of all CT scans with the open-source software platform Horos was used to evaluate the QCT indices. Patients were classified according to the extent of ILD and differences in QCT index distribution were investigated with non-parametric tests. RESULTS: From a total of 102 consecutive patients with SS, the prevalence of ILD was 35.3% (36/102). There was a statistically significant difference in QCT index distribution between the SS with ILD and SS without ILD groups (p<0.001). Moreover, SS-ILD patients with ILD >20% (by Goh score) had a QCT index statistically different from those with limited ILD extent (p<0.001). Finally, QCT indices showed a moderate-to-good correlation with the Goh and Taouli scores (from 0.44 to 0.65; p<0.001). CONCLUSIONS: QCT indices can identify patients with SS and ILD and discriminate those with lesser or greater lung disease.
