SARS-CoV-2 Vaccination in Solid-Organ Transplant Recipients

The coronavirus disease 2019 (COVID-19) pandemic has posed significant global challenges for solid organ transplant (SOT) recipients. Mortality rates of COVID-19 in this patient population remain high, despite new available therapeutic options and Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccination. Priority access to SARS-CoV-2 vaccination for waitlisted candidates and for SOT patients and their family members is recommended since the advantage from vaccination reduces the risk of COVID-19-related complications. However, immunogenicity and efficacy of COVID-19 vaccines are lower in waitlisted candidates and SOT recipients than in the general population. Routine systematic assessment of humoral and cellular immune responses after SARS-CoV-2 vaccination is controversial, although highly recommended for investigation and improvement of knowledge. SOT recipients should continue to adhere to preventive protective measures despite vaccination and may undergo passive antibody prophylaxis. This article seeks to provide an update on SARS-CoV-2 vaccination and preventive measures in SOT recipients based on existing literature and international guidelines

Treatment of Bloodstream Infections Due to Gram-Negative Bacteria with Difficult-to-Treat Resistance

The rising incidence of bloodstream infections (BSI) due to Gram-negative bacteria (GNB) with difficult-to-treat resistance (DTR) has been recognized as a global emergency. The aim of this review is to provide a comprehensive assessment of the mechanisms of antibiotic resistance, epidemiology and treatment options for BSI caused by GNB with DTR, namely extended-spectrum Beta-lactamase-producing Enterobacteriales; carbapenem-resistant Enterobacteriales; DTR Pseudomonas aeruginosa; and DTR Acinetobacter baumannii

Il mosaico della Sardegna interna come “cultura delle differenze”

Il Piano paesaggistico della Sardegna ha radicalmente innovato la cultura del paesaggio in ambito regionale, avviando per la prima volta una moderna strategia delle “identità sostenibili” e dandole strumenti che ancora, dopo 15 anni, dimostrano una sostanziale tenuta. Tuttavia, nel 2004 il PPR viene impostato per fare argine all’occupazione edilizia del territorio costiero, e rinvia sostanzialmente la “questione rurale”, largamente sovrapposta al tema delle Aree interne, proprio quelle rimaste escluse dal PPR stesso. Anche se questa indispensabile integrazione a distanza di 15 anni non si è ancora concretizzata, a partire dal 2015 si dà avvio ad un progetto di ricerca congiunta Regione-Università dedicato ai paesaggi rurali, destinato a colmare, almeno in parte, il divario di conoscenze e di linee guida progettuali in materia. Peraltro, questa ricerca si svolge in un momento in cui le grandi crisi contemporanee danno una nuova prospettiva alle strategie per lo sviluppo sostenibile. In particolare – come del resto era stato già anticipato nei principi posti alla base del PPR - quello che è stato percepito a lungo come un vincolo, la modernizzazione imperfetta e lo sviluppo insufficiente e comunque continuamente interrotto, alla luce dei concetti di resilienza/antifragilità, e di transizione ecologica, può essere interpretato invece come una risorsa. Questo saggio propone un primo bilancio di questa ricerca, della sua impostazione e dei suoi esiti. E giunge alla conclusione che nell’era delle grandi crisi, pandemiche e soprattutto climatiche, e del Green Deal europeo, il paesaggio rurale assume nuovi e decisivi ruoli

Clinical presentation and immunological features of Post-Malaria Neurologic Syndrome: a case report and review of literature

BackgroundMalaria still represents a major health threat, in terms of both morbidity and mortality. Complications of malaria present a diversified clinical spectrum, with neurological involvement leading to the most serious related-conditions. The authors recently encountered a case of a 60-year old Italian man presenting with confusion, language disturbances and Parkinson-like syndrome 3 weeks after complete remission from severe Plasmodium falciparum cerebral malaria. Chemical and microbiological analysis revealed aseptic meningitis, diffuse encephalitis and abnormal immune-activation. Re-infection and recrudescence of infection were excluded. Further analysis excluded paraneoplastic and autoimmune causes of encephalitis. A diagnosis of Post-Malaria Neurological Syndrome (PMNS) was finally formulated and successfully treated with high dose of steroids.MethodsA systematic research of current literature related to PMNS was performed.Results151 cases of PMNS were included, the majority of which occurred after severe P. falciparum infections. Four main clinical pattern were identified: 37% of the cases presented as "classical" PMNS, 36% presented as delayed cerebellar ataxia (DCA), 18% resembled acute inflammatory demyelinating polyneuropathy (AIDP), and 8% presented as acute disseminated encephalomyelitis (ADEM)-like form. Differentiation between different forms was not always simple, as clinical and radiological findings frequently overlap. Overall, in almost all of the tested cases, cerebrospinal fluid was found pathological; EEG revealed nonspecific encephalopathy in 30% of classical PMNS and 67% ADEM; imaging tests were found abnormal in 92% of ADEM-like forms. Pathogenesis remains unclear. An autoimmune mechanism is the most corroborated pathogenic hypothesis. Overall, the majority of PMNS cases revert without specific treatment. In most severe forms, high dose steroids, intravenous immunoglobulins, and plasmapheresis have been shown to improve symptoms.ConclusionsPMNS is a disabling complication of malaria. The overall incidence is not known, due to frequent misdiagnosis and under-reporting. Pathogenesis is not also fully understood, but rapid response to immune-modulating treatment along with similarities to auto-immune neurological disease, strongly support a dysregulated immunological genesis of this condition. The lack of randomized controlled studies regarding therapeutic approaches is a major unmet need in this setting. A systematic collection of all the PMNS cases would be desirable, in order to increase awareness of this rare condition and to prospectively investigate the most appropriate management

Performance of Existing Definitions and Tests for the Diagnosis of Invasive Fungal Diseases other than Invasive Candidiasis and Invasive Aspergillosis in Critically Ill, Adult Patients: A Systematic Review with Qualitative Evidence Synthesis

Diagnòstic; Malalties fúngiques invasores; PneumocystisDiagnóstico; Enfermedades fúngicas invasivas; PneumocystisDiagnosis; Invasive fungal diseases; PneumocystisThe Fungal Infections Definitions in Intensive Care Unit (ICU) patients (FUNDICU) project aims to provide standard sets of definitions for invasive fungal diseases (IFDs) in critically ill, adult patients, including invasive aspergillosis (IA), invasive candidiasis (IC), Pneumocystis jirovecii pneumonia (PJP), and other non-IA, non-IC IFDs. The first step of the project was the conduction of separated systematic reviews of the characteristics and applicability to critically ill, adult patients outside classical populations at risk (hematology patients, solid organ transplant recipients) of available definitions and diagnostic tests for IFDs. We report here the results of two systematic reviews exploring the performance of available definitions and tests, for PJP and for other non-IA, non-IC IFDs. Starting from 2585 and 4584 records for PJP and other IFDs, respectively, 89 and 61 studies were deemed as eligible for full-text evaluation. However, only two studies for PJP and no studies for other IFDs met the FUNDICU protocol criteria for inclusion in qualitative synthesis. Currently, there is no sufficient solid data for directly evaluating the performance of existing definitions and laboratory tests for the diagnosis of PJP and other non-IA, non-IC IFDs in critically ill adult patients outside classical populations at risk.The present project did not require additional funding from routine research activities. Costs for open-access publications were covered by research funds of the main authors

Fungal endogenous endophthalmitis secondary to magnusiomyces capitatus

We report the case of a 68-year-old immunocompetent patient with a dilatation of the ascending aorta, intraluminal vegetations, and pseudoaneurysmatic bulging who presented with unilateral fungal endogenous endophthalmitis 8 days after coronary angiogram. The isolated pathogen resulted to be Magnusiomyces capitatus, a filamentous, yeast-like fungus that can be commonly found in normal human microflora, with an immunosuppression-related pathogenicity. A literature research revealed a single case of ophthalmic infection - a keratitis - caused by this pathogen. Furthermore, we add a review of mycotic endophthalmitis related to aortic infection

One Word to Describe My Experience as a COVID-19 Survivor Six Months after Its Onset: Findings of a Qualitative Study

The COVID-19 pandemic emotionally affected the lives of patients cared for in different settings. However, a comprehensive view of the whole experience as lived by survived patients, from the onset of the disease and over time, is substantially unknown to date. A descriptive qualitative design was implemented according to the Standards for Reporting Qualitative Research. Adult patients (=1067) cared for during the first wave (March/April 2020) capable of answering an interview and willing to participate were interviewed (=397) by phone with an interview guide including open- and closed-ended questions. In this context, they were asked to summarise with a metaphor their entire COVID-19 experience at six months. Then, the emotional orientation (positive, neutral, or negative) of the metaphors expressed was identified. The participants were mainly female (206; 51.9%), with an average age of 52.6 years (CI 95% 50.4-53.6), reporting a mild severity of COVID-19 disease at the onset (261; 65.7%) and the perception of being completely healed (294; 70%) at six months. The patients summarised their experiences mainly using negative-oriented (248; 62.5%) metaphors; only 54 (13.6%) reported positive-oriented metaphors and a quarter (95; 23.95) neutral-oriented metaphors. Nearly all positive-oriented metaphors were reported by patients with symptoms at the onset (53; 98.1%), a significantly higher proportion compared to those reporting negative- (219; 88.3%) and neutral-oriented (78; 82.1%) metaphors (p = 0.014). While no other clinical features of the disease were associated, among females, significantly more negative-oriented metaphors emerged. Moreover, neutral-oriented metaphors were reported by younger patients (49.5 years, CI 95% 64.11-52.92) as compared to those negative and positive that were reported by more mature patients (53.9; CI 95% 52.04-55.93 and 54.8; CI 95% 50.53-59.24, respectively) (p = 0.044). Nurses and healthcare services require data to predict the long-term needs of patients. Our findings suggest that, for many patients, the COVID-19 lived experience was negative over time

Short-term cardiac outcome in survivors of COVID-19: a systematic study after hospital discharge

Background COVID-19 has caused considerable morbidity and mortality worldwide and cardiac involvement has been reported during infection. The short-term cardiac outcome in survivors of COVID-19 is not known.Objective To examine the heart of patients who survived COVID-19 and to compare the cardiac outcome between patients who recovered from mild-to-moderate or severe illness.Methods With use of ECG and echocardiography, we examined the heart of 105 patients who had been hospitalized with COVID-19 and were consecutively recruited after hospital discharge while attending follow-up visits. Survivors of COVID-19 were compared with 105 matched controls. We also compared the cardiac outcome and lung ultrasound scan between COVID-19 patients who had mild-to-moderate or severe illness.Results Cardiac data were collected a median of 41 days from the first detection of COVID-19. Symptoms were present in a low percentage of patients. In comparison with matched controls, no considerable structural or functional differences were observed in the heart of survivors of COVID-19. Lung ultrasound scan detected significantly greater residual pulmonary involvement in COVID-19 patients who had recovered from severe than mild-to-moderate illness. No significant differences were detected in ECG tracings nor were found in the left and right ventricular function of patients who had recovered from mild-to-moderate or severe illness.Conclusions In a short-term follow-up, no abnormalities were identified in the heart of survivors of COVID-19, nor cardiac differences were detected between patients who had different severity of illness. With the limitations of a cross-sectional study, these findings suggest that patients who recover from COVID-19 do not have considerable cardiac sequelae.[GRAPHICS]

The burden of severe cases of Influenza disease: The Friuli Venezia Giulia Region experience

IIntroduction. Influenza is a matter of serious concern for clinicians, in both outpatient and in-hospital settings. Worldwide, the 2017-18 epidemic proved to be the most severe since 2003-04. We report a real-world experience regarding the management of patients with influenza admitted to a large teaching hospital in the Friuli Venezia Giulia region during the 2017-2018 influenza season. We also provide a practical guide for the management of hospitalized influenza patients. Methods. A retrospective observational analysis was conducted among all influenza patients requiring admission to our center during the 2017-18 season. Results. Overall, 29 patients were admitted to the University Hospital of Udine during the 2017-18 season with a diagnosis of influenza. B virus was responsible for the majority of cases. More than 65.5% of the subjects presented with a complication. We estimated that 41.4% of the patients admitted were affected by a \u201csevere form\u201d. All these cases required admission to the Intensive Care Unit, with 27.6% and 10.3% needing Orotracheal Intubation and Extracorporeal Membrane Oxygenation, respectively. The fatality rate was 24.1%. Notably, only 9 subjects in our cohort had been vaccinated. Based on the experience acquired during the past season, we propose a practical guide to the management of influenza cases in everyday hospital practice. Conclusion. The cornerstones of the management of all hospitalized influenza patients are the rapid identification and treatment of severe forms. Timely and strict adherence to contact and respiratory precautions are also fundamental to reducing the risk of intra-hospital outbreaks. Despite improvements in antiviral therapies and supportive measures, influenza-related morbidity and mortality remain high. In our opinion, a universal vaccination program is the only safe and effective method of filling the gap
