Patients with Chronic Lymphocytic Leukemia Have a Very High Risk of Ineffective Response to the BNT162b2 Vaccine.

Patients with CLL have high rates of either severe disease or death from COVID-19 and a low response rate after COVID-19 vaccination has been reported. We conducted a single-center study with the main objective to evaluate the immunogenicity of the BNT1162b2 mRNA vaccines in 42 patients affected by CLL with the assessment of antibody response after the second and the third dose. After the second dose of vaccine, 13 patients (30%) showed an antibody response. The presence of hypogammaglobulinemia and the use of steroids or IVIG were the main factors associated with poor response. After the third dose, 5/27 (18%) patients showed an antibody response while in non-responders to the second dose, only 1 patient (4%) showed an elicitation of the immune response by the third dose, with no statistically significant difference. Our data, despite the small size of our cohort, demonstrate that patients with CLL have a low rate of effective response to the BNT162b2 vaccine. However, the effective role of a subsequent dose is still unclear, highlighting the need for alternative methods of immunization in this particularly fragile group of patients.

Severe myopathy complicating multisystem inflammatory syndrome in adults (MIS-A) in a young man.

We report the case of a man in his early 30s who presented with high fever, cervical lymphadenopathy, maculopapular rash and considerably elevated inflammatory markers. Further evaluations revealed cardiomyopathy and renal failure. During hospitalisation he developed profound generalised muscle weakness caused by diffuse myopathy without elevated creatine kinase. He was eventually diagnosed with multisystem inflammatory syndrome in adults (MIS-A) after it was established that he had been suffering from COVID-19 5 weeks prior to presentation. He was started on intravenous immunoglobulins and high-dose corticosteroids, after which symptoms resolved rapidly. MIS-A is a rare but severe complication of COVID-19, whose pathogenesis is insufficiently understood. This case provides further insight into this new disease entity by describing a previously unreported disease progression with severe inflammatory myopathy without elevated creatine kinase.

Mental Health Impact and Burnout in Critical Care Staff During Coronavirus Disease 2019 Outbreak.

OBJECTIVE: The coronavirus disease 2019 outbreak exposed intensive care unit health care workers to a psychological burden. The aim of the study was to assess burnout, depression, anxiety, and post-traumatic stress symptoms in the intensive care unit staff during the pandemic period and to focus on the factors that contributed to psychological discomfort by using validated psychometric tools. METHODS: This was a monocentric study developed at the end of the first emergency crisis period (May 2020). We used a custom-designed survey using SurveyMonkey. The first part of the online survey included 27 general questions (sociodemographic information, the professional role, and possible changes assigned in job tasks and duties), the second part included validated psychometric tools: Maslach Burnout Inventory, General Health Questionnaire-12 Items, Impact of Event Scale, Beck Anxiety Inventory, and Beck Depression Inventory-II. Factors indepen- dently associated with reported symptoms of mental health disorders were identified. RESULTS: The response rate was 88%, with 95 respondents. Depressive and mild-moderate anxiety symptoms were reported in 20% and in 12% of health care workers, respectively, and half of the sample experienced moderate or severe post-traumatic stress symptoms. In total, 64% of health care workers reported high levels of burnout. General mental health problems were more frequently reported by women (P =.3), by those who were tested negative for the coronavirus disease 2019 buffer (P < .02), and by those who changed their family habits (P =.02) as a consequence of the pandemic. Being single or divorced (P = .04) was associated with the presence of depressive symptoms; vice versa, cohabiting with a partner or being married was associated with lower levels of depression. Anxious symptoms were reported in health care workers with no previous working experience in the intensive care unit. CONCLUSIONS: Health care workers experience high levels of psychological burden during the coronavirus disease 2019 pandemic. Knowing the risk factors can aid to develop strategies of observation and prevention and also strengthen the ability to be resilient to stressful situations.

How to Build the Plane While Flying: VTE/PE Thromboprophylaxis Clinical Guidelines for COVID-19 Patients.

Over the years, the practice of medicine has evolved from authority-based to experience-based to evidence-based with the introduction of the scientific process, clinical trials, and outcomes-based data analysis (Tebala GD. Int J Med Sci. 2018;15(12):1397-1405). The time required to perform the necessary randomized controlled trials, a systematic literature review, and meta-analysis of these trials to then create, accept, promulgate, and educate the practicing clinicians to use the evidence-based clinical guidelines is typically measured in years. When the severe acute respiratory syndrome novel coronavirus-2 (SARS-nCoV-2) pandemic commenced in Wuhan, China at the end of 2019, there were few available clinical guidelines to deploy, let alone adapt and adopt to treat the surge of coronavirus disease 2019 (COVID-19) patients. The aim of this study is to first explain how clinical guidelines, on which bedside clinicians have grown accustomed, can be created in the midst of a pandemic, with an evolving scientific understanding of the pathophysiology of the hypercoagulable state. The second is to adapt and adopt current venous thromboembolism diagnostic and treatment guidelines, while relying on the limited available observational reporting of COVID-19 patients to create a comprehensive clinical guideline to treat COVID-19 patients.
