RESUMEN
BACKGROUND: Viral community-acquired pneumonia (CAP) is a potentially serious illness, particularly in adult patients with underlying chronic conditions. In addition to the most recent SARS-CoV-2, influenza, and respiratory syncytial virus (RSV) are considered the most relevant causes of viral CAP. AIMS: To describe the clinical features of hospitalised adults admitted for influenza-A/B and RSV pneumonia and analyse, according to aetiology, factors associated with non-invasive ventilation (NIV) failure and in-hospital death (IHD). METHODS: This was a retrospective and multi-centre study of all adults who were admitted for laboratory-confirmed influenza-A/B or RSV pneumonia, during two consecutive winter seasons (October-April 2017-2018 and 2018-2019) in three tertiary hospitals in Portugal, Italy and Cyprus. RESULTS: A total of 356 adults were included in the study. Influenza-A, influenza-B and RSV were deemed to cause pneumonia in 197 (55.3%), 85 (23.9%) and 74 (20.8%) patients, respectively. Patients with both obstructive sleep apnoea or obesity hypoventilation syndrome and influenza-A virus pneumonia showed a higher risk for NIV failure (odds ratio (OR) 4.66; 95% confidence interval (CI) 1.42-15.30). Patients submitted to NIV showed a higher risk for IHD, regardless of comorbidities (influenza-A OR 3.00; 95% CI 1.35-6.65, influenza-B OR 4.52; 95% CI 1.13-18.01, RSV OR 5.61; 95% CI 1.26-24.93). CONCLUSION: The increased knowledge of influenza-A/B and RSV pneumonia burden may contribute to a better management of patients with viral CAP.

INTRODUCTION: Acute liver failure (ALF) due to diffuse infiltrating solid malignancy without any focal lesions on radiographic imaging is rare. CASE REPORT: A 70-year-old man was admitted due to mental confusion, abdominal pain, and ALF. Three years before, he had undergone a left nephrectomy for urothelial carcinoma followed by adjuvant chemotherapy. The abdominal computed tomography (CT) showed hepatomegaly and ascites. Ascitic fluid had transudate characteristics, with no malignant cells. Percutaneous liver biopsy (LB) showed diffuse liver infiltration of metastatic urothelial carcinoma. The patient rapidly deteriorated and died in a week due to ALF. DISCUSSION: History of solid cancer and hepatomegaly and/or liver failure without other obvious explanation should encourage to perform LB. CONCLUSION: LB is warranted to avoid misdiagnosis, prolonged hospital stays, and delay in palliative care.
RESUMEN
In Europe, the respiratory syncytial virus (RSV) surveillance system is very heterogeneous and there is growing evidence of the importance of RSV infections resulting in hospitalization of elderly patients. The aim of this study was to assess the severity of RSV infection in the elderly living in the aged Southern European countries. We conducted a retrospective study of elderly patients ( ≥65-year old) admitted for laboratory-confirmed RSV infection in three tertiary hospitals in Portugal, Italy, and Cyprus over two consecutive winter seasons (2017-2018). Uni-multivariable analyses were carried out to evaluate the effect of clinical variables on radiologically confirmed pneumonia, use of noninvasive ventilation (NIV), and in-hospital death (IHD). A total of 166 elderly patients were included. Pneumonia was evident in 29.5%. NIV was implemented in 16.3%, length of stay was 11.8 ± 12.2 days, and IHD occurred in 12.1%. Multivariable analyses revealed that the risk of pneumonia was higher in patients with chronic kidney disease (CKD) (odds ratio [OR]: 2.57; 95% confidence interval [CI]: 1.12-5.91); the use of NIV was higher in patients with obstructive sleep apnea or obesity hypoventilation syndrome (OSA or OHS) (OR: 5.38; 95% CI: 1.67-17.35) and CKD (OR: 2.52; 95% CI: 1.01-6.23); the risk of IHD was higher in males (OR: 3.30; 95% CI: 1.07-10.10) and in patients with solid neoplasm (OR: 9.06; 95% CI: 2.44-33.54) and OSA or OHS (OR: 8.39; 95% CI: 2.14-32.89). Knowledge of factors associated with RSV infection severity may aid clinicians to set priorities and reduce disease burden. Development of effective antiviral treatment and vaccine against RSV is highly desirable.

OBJECTIVES: Our study aimed to compare the clinical severity of lower respiratory tract infections (LRTI's) caused by Influenza and Respiratory Syncytial Virus (RSV). METHODS: We conducted a retrospective cohort study of LRTI admissions with positive PCR results for Influenza or RSV from 2017 to 2019 in three teaching hospitals in southern Europe. Data on clinical characteristics, viral agents and disease outcome were collected. Nosocomial infection was excluded. Main outcomes were invasive mechanical ventilation and in-hospital death. RESULTS: A total of 984 patients were included. Median age was 75 years. Influenza A was the most frequently identified virus (56.5%), of which 27.1% were subtype H1N1 and 53.0% H3N2. Influenza B was isolated in 22.3% and RSV in 21.0%. There were 10.5% of patients who died during admission and 8.3% submitted to IMV. Influenza A H1N1 was associated with lower age and less co-morbidity, while the opposite was observed for RSV. Influenza A H1N1 was independently associated with both higher risk of death (adjusted odds ratio 2.0 [1.2-3.4] p = 0.008) and IMV (adjusted odds ratio 5.1 [3.0-8.5] p < 0.001). CONCLUSION: Influenza A H1N1 was an independent predictor of mortality and IMV. These findings may have implications on hospital resource planning and vaccination policies.

SARS-CoV-2 dramatically revealed the sudden impact of respiratory viruses in our lives. Influenza and respiratory syncytial virus (RSV) infections are associated with high rates of morbidity, mortality, and an important burden on healthcare systems worldwide, especially in elderly patients. The aim of this study was to identify severity predictors in the oldest-old admitted with influenza and/or RSV infections. This is a multicenter, retrospective study of all oldest-old patients (≥ 85 years old) admitted for laboratory-confirmed influenza and/or RSV infection in three tertiary hospitals in Portugal, Italy, and Cyprus over two consecutive winter seasons. The outcomes included the following: pneumonia on infection presentation, use of non-invasive ventilation (NIV), and in-hospital death (IHD). The association with possible predictors, including clinical features and type of virus infection, was assessed using uni- and multivariable analyses. A total of 251 oldest-old patients were included in the study. Pneumonia was evident in 32.3% (n = 81). NIV was implemented in 8.8% (n = 22), and IHD occurred in 13.9% (n = 35). Multivariable analyses revealed that chronic obstructive pulmonary disease (COPD) or asthma was associated with pneumonia (OR 1.86; 95% CI 1.02-3.43; p = 0.045). COPD or asthma (OR 4.4; 95% CI 1.67-11.6; p = 0.003), RSV (OR 3.12; 95% CI 1.09-8.92; p = 0.023), and influenza B infections (OR 3.77; 95% CI 1.06-13.5; p = 0.041) were associated with NIV use, respectively, while chronic kidney disease was associated with IHD (OR 2.50; 95% CI 1.14-5.51; p = 0.023). Among the oldest-old, chronic organ failure, such as COPD or asthma, and CKD predicted pneumonia and IHD, respectively, beyond the importance of viral virulence itself. These findings could impact on public health policies, such as fostering influenza immunization campaigns, home-based care programs, and end-of-life care. Filling knowledge gaps is crucial to set priorities and advise on transition model of care that best fits the oldest-old.

Leptospirosis is a zoonotic disease of worldwide distribution caused by infection with Leptospira genus bacteria, a pathogenic spirochaete. We present the case of a 29-year-old man admitted to our hospital with fever and multiorgan failure. He provided poor information about his symptoms. No recent travel or occupational history was reported and his clinical presentation did not suggest any infectious foci. His relatives later disclosed that he had been homeless for 3 weeks in the context of behavioural changes, obtaining foodstuff from waste containers and water from rain puddles. In the setting of this epidemiology, his presentation of fever, jaundice, acute renal injury and thrombocytopaenia suggested leptospirosis. Prompt empirical antimicrobial coverage was started, alongside organ support therapy. The diagnosis was later confirmed through microscopical and molecular methods. The patient made a full recovery. Leptospirosis should be considered early in the diagnostic work-up of any patient with acute febrile illness with multiorgan system involvement, with the identification of risk factors being essential to treat early in development of the disease.

The authors report the case of an 86-year-old woman presenting with recurrent Klebsiella pneumoniae bacteraemia. She had severe aortic stenosis submitted to a recent transcatheter aortic valve implantation (TAVI). Initially, Klebsiella pneumoniae bacteraemia from a urinary source was diagnosed. Following another 4 episodes of bacteraemia with the same agent, the source was ultimately found to be a periprosthetic abscess. Considering the patient's unsuitability for surgery, a decision was made for life-long antimicrobial therapy. This approach has been successful in preventing recurrences or complications. Endocarditis is one of the most severe complications seen following TAVI, often carrying a poor prognosis. Even though Klebsiella spp. are common pathogens for healthcare-associated infections among the elderly, they are seldom the causative agent for endocarditis. Being the first reported case of TAVI-related Klebsiella endocarditis, it was successfully managed using a medical approach. LEARNING POINTS: Non-HACEK Gram-negative bacilli are organisms infrequently found to cause infective endocarditis (IE). This is the first reported case of transcatheter aortic valve implantation (TAVI)-related Klebsiella IE.Diagnosing an infectious complication associated with procedural or prosthetic material is not always straightforward; a high level of suspicion and a systematic approach are essential.Most cases of TAVI-related IE are ineligible for surgery due to a prohibitive procedural risk. Long-term antibiotic therapy may be a suitable alternative for patients with uncontrolled infection considered unfit for surgery.

Hepatic hydrothorax, a rare and debilitating complication of cirrhosis, carries high morbidity and mortality. First-line treatment consists of dietary sodium restriction and diuretic therapy. Some patients, mainly those who are refractory to medical management, will require invasive pleural drainage. The authors report the case of a 76-year-old man in a late cirrhotic stage of alcoholic chronic liver disease, presenting with recurrent right-sided hepatic hydrothorax, portal hypertension, hepatosplenomegaly and thrombocytopaenia. After recurrent admissions and complications, the potential for adjusting diuretic therapy was limited. After unsuccessful talc pleurodesis, an indwelling tunnelled pleural catheter was placed with effective symptomatic control. One month later, the patient was readmitted with empyema due to Acinetobacter radioresistens Despite optimised medical and surgical treatment, the patient died 4 weeks later.

We performed a retrospective analysis of clinical and laboratory data over 5 years in a tertiary centre to assess clinical and microbiological characteristics of patients with Raoultella spp. infection. Raoultella spp. were deemed responsible for clinical infections in 57 patients (R. planticola, n = 32 and R. ornithinolytica, n = 25). The most prevalent diagnoses for R. planticola were cystitis (50%; n = 16) followed by bacteraemia and pneumonia (9.4%; n = 3); for R. ornithinolytica, cystitis (36%; n = 9) followed by pneumonia (24%; n = 6). Immunodeficiency was present in 18 patients (56.3%) with R. planticola and in 16 patients (64%) with R. ornithinolytica infection. Of these, 55.6% and 37.5% had diabetes and 27.8% and 18.% were solid organ transplant recipients, respectively. All isolates were sensitive to third-generation cephalosporins, fluoroquinolones and aminoglycosides. Mortality of infections with R. planticola (n = 5; 15.6%) was higher than for R. ornithinolytica (n = 2; 8.0%), but the difference was not statistically significant.
