Effectiveness, barriers and facilitating factors of strategies for active delabelling of patients with penicillin allergy labels: a systematic review protocol.

Introduction: Up to 15% of adult patients in the clinical setting report to be allergic to penicillin. However, in most cases, penicillin allergy is not confirmed. Due to the negative aspects associated with erroneous penicillin allergy, the implementation of active delabelling processes for penicillin allergy is an important part of antibiotic stewardship programmes.

Accumulation of mutations in antibody and CD8 T cell epitopes in a B cell depleted lymphoma patient with chronic SARS-CoV-2 infection.

Antibodies against the spike protein of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) can drive adaptive evolution in immunocompromised patients with chronic infection. Here we longitudinally analyze SARS-CoV-2 sequences in a B cell-depleted, lymphoma patient with chronic, ultimately fatal infection, and identify three mutations in the spike protein that dampen convalescent plasma-mediated neutralization of SARS-CoV-2. Additionally, four mutations emerge in non-spike regions encoding three CD8 T cell epitopes, including one nucleoprotein epitope affected by two mutations.

[Management of infection in immunocompromised patients].

The number of immunosuppressed patients continues to increase worldwide. The main reasons are the demographic development and improved long-term survival, also for patients under immunosuppression. A major cause of hospitalization and mortality among these patients are infections.

Intracerebral mucormycosis after COVID-19: illustrative cases.

Background: In this case report the authors present two female patients with intracranial mucormycosis after coronavirus disease 2019 (COVID-19).

Observations: The first patient was a 30-year-old woman with no past medical history or allergies who presented with headaches and vomiting. Magnetic resonance imaging (MRI) and computed tomography of the skull showed an endonasal infection, which had already destroyed the frontal skull base and caused a large frontal intracranial abscess.

Should routine risk reduction procedures for the prevention and control of pandemics become a standard in all oncological outpatient clinics? The prospective COVID-19 cohort study: protect-CoV.

Limited knowledge exists on the effectiveness of preventive preparedness plans for the care of outpatient cancer patients during epidemics or pandemics. To ensure adequate, timely and continuous clinical care for this highly vulnerable population, we propose the establishment of preventive standard safety protocols providing effective early phase identification of outbreaks at outpatient cancer facilities and communicating adapted standards of care. The prospective cohort study Protect-CoV conducted at the LMU Klinikum from mid-March to June 2020 investigated the effectiveness of a rapid, proactive and methodical response to protect patients and interrupt SARS-CoV-2 transmission chains during the first pandemic wave.

Presence of mediated linezolid resistance in multiple lineages and plasmids of revealed by long read sequencing.

Transferable linezolid resistance due to , , and -like genes is increasingly detected in enterococci associated with animals and humans globally. We aimed to characterize the genetic environment of in linezolid-resistant isolates from Scotland. Six linezolid-resistant isolated from urogenital samples were confirmed to carry the gene by PCR.

Results from a national survey on COVID-19-associated mucormycosis in Germany: 13 patients from six tertiary hospitals.

Background: Most COVID-19-associated mucormycosis (CAM) cases are reported from India and neighbouring countries. Anecdotally cases from Europe have been presented.

Objective: To estimate the disease burden and describe the clinical presentation of CAM in Germany.

Sensitivity of two SARS-CoV-2 variants with spike protein mutations to neutralising antibodies.

SARS-CoV-2 infections elicit a humoral immune response capable of neutralising the virus. However, multiple variants have emerged with mutations in the spike protein amongst others, the key target of neutralising antibodies. We evaluated the neutralising efficacy of 89 serum samples from patients, infected with SARS-CoV-2 in the beginning of 2020, against two virus variants isolated from acutely infected patients and harbouring spike protein mutations.

Rituximab Treatment of Hairy Cell Leukemia in a Patient with Mycobacterium kansasii Infection: A Case Report.

Introduction: Infectious complications represent a major cause of morbidity and mortality in hairy cell leukemia (HCL) patients. Due to the immunosuppressive nature of the disease, these patients are frequently affected by opportunistic infections and rare pathogens. Furthermore, cytotoxic chemotherapy might lead to poor or even fatal outcomes in the setting of an active infection.

Equity for excellence in academic institutions: a manifesto for change.

Higher academic institutions in the UK need to drive improvements in equity, diversity, and inclusion (EDI) through sustainable practical interventions. A broad view of inclusivity is based on an intersectional approach that considers race, geographical location, caring responsibilities, disability, neurodiversity, religion, and LGBTQIA+ identities. We describe the establishment of a diverse stakeholder group to develop practical grass-roots recommendations through which improvements can be advanced.

Pulmonary function impairment of asymptomatic and persistently symptomatic patients 4 months after COVID-19 according to disease severity.

Objective: Evaluation of pulmonary function impairment after COVID-19 in persistently symptomatic and asymptomatic patients of all disease severities and characterisation of risk factors.

Methods: Patients with confirmed SARS-CoV-2 infection underwent prospective follow-up with pulmonary function testing and blood gas analysis during steady-state cycle exercise 4 months after acute illness. Pulmonary function impairment (PFI) was defined as reduction below 80% predicted of DLCOcSB, TLC, FVC, or FEV1.

[Update 2021: COVID-19 from the perspective of infectious diseases specialty].

From an infectious disease perspective, there have been outstanding findings since January 2020 far beyond the knowledge gained about SARS-CoV, which hopefully will help us to manage future pandemics. Positive highlights include the increased public awareness of infectious disease epidemiology, the increase in immunological knowledge, and the successful use of existing vaccine development platforms and technologies. This article presents a personal selection of interesting developments in recent months.

COVID-19 in Patients Receiving CD20-depleting Immunochemotherapy for B-cell Lymphoma.

The clinical and immunological impact of B-cell depletion in the context of coronavirus disease 2019 (COVID-19) is unclear. We conducted a prospectively planned analysis of COVID-19 in patients who received B-cell depleting anti-CD20 antibodies and chemotherapy for B-cell lymphomas. The control cohort consisted of age- and sex-matched patients without lymphoma who were hospitalized because of COVID-19.

Liver transplantation in a patient after COVID-19 - Rapid loss of antibodies and prolonged viral RNA shedding.

To date, little is known about the duration and effectiveness of immunity as well as possible adverse late effects after an infection with SARS-CoV-2. Thus it is unclear, when and if liver transplantation can be safely offered to patients who suffered from COVID-19. Here, we report on a successful liver transplantation shortly after convalescence from COVID-19 with subsequent partial seroreversion as well as recurrence and prolonged shedding of viral RNA.

[COVID-19: Questions and answers from infectiology].

The control and management of infection with the novel SARS-CoV-2 virus requires multidisciplinary work between specialists on all levels. This article aims to provide an overview of the current knowledge of COVID-19 from the view of infectious diseases physicians including all the uncertainties of our understanding of the pathogenesis and immunity.

Urinary Frequency as a Possibly Overlooked Symptom in COVID-19 Patients: Does SARS-CoV-2 Cause Viral Cystitis?

The current coronavirus disease 2019 (COVID-19) pandemic is a challenge for physicians in triaging patients in emergency rooms. We found a potentially dangerous overlap of classical urinary symptoms and the as yet not fully described symptoms of COVID-19. After a patient was primarily triaged as a urosepsis case and then subsequently diagnosed with COVID-19, we focused on an increase in urinary frequency as a symptom of COVID-19 and identified this in seven males out of 57 patients currently being treated in our COVID-19 wards.

Oral versus intravenous antibiotics for bone and joint infections: the OVIVA non-inferiority RCT.

Background: Management of bone and joint infection commonly includes 4-6 weeks of intravenous (IV) antibiotics, but there is little evidence to suggest that oral (PO) therapy results in worse outcomes.

Objective: To determine whether or not PO antibiotics are non-inferior to IV antibiotics in treating bone and joint infection.

Design: Parallel-group, randomised (1 : 1), open-label, non-inferiority trial.
