Acute Approach to Central Nervous System Infections in Kazakhstan

Background Neuroinfections in children are a socially significant problem of our time, as they can lead to disability and death of the patient, which actualizes the need for their early clinical diagnosis. The purpose of the study: to identify patterns of clinical manifestations of central nervous system lesions in children with neuroinfections. Materials and methods The cases of neuroinfections in 101 children treated at the “City Clinical Infectious Diseases Hospital” (Shymkent) in the period from 2018 to 2022 were analyzed, of which 37 patients with viral neuroinfections, 64 with bacterial ones. Results The predominance of bacterial neuroinfections over viral ones was revealed, with a predominance among young boys. Headache or its equivalents (in children under one year old) were observed in 72.5%; most often in children with viral infections of the nervous system (81.2%), less often in patients with bacterial infections (65.4%), p 0.01. In most cases, the disease manifested with the phenomena of fever and vomiting. When assessing the neurological status, the duration of preservation of two frequently occurring meningeal signs (rigidity of the occipital muscles, Kernig’s symptom) was taken into account, which was 6 ± 1.3 days and 5 ± 1.1 days in the group with bacterial neuroinfections, and 4 ± 1.8 and 5 ± 1.7 days, respectively, in the group with viral neuroinfections (p 0.05). With pneumococcal etiology, the most severe and protracted cases of the course of neuroinfections are recorded. Frequent emergency conditions in infectious lesions of the central nervous system in the form of cerebral edema, septic shock, which occur more often in bacterial neuroinfections, have been identified. Conclusion Neuroinfections are characterized by a symptom complex of clinical manifestations, which should be interpreted by doctors in a timely and correct manner in order to diagnose early and minimize adverse outcomes of the disease.

Assessing the Psychological Well-being of Healthcare Workers During the COVID-19 Pandemic

During the COVID-19 pandemic, working in any medical organization is associated with the risk of coronavirus infection. This applies first and foremost to specialized medical organizations dealing with the treatment of patients infected with coronavirus. Medical workers experiencing increased psychological stress are at an increased risk of infection with the SARS-CoV-2 virus while providing medical care. Therefore, studying the psychological states of medical workers – doctors, nurses, orderlies - is of particular importance and relevance. Our research goal is to investigate the psychological responses of medical professionals amid the COVID-19 pandemic. The research focused on the Aktobe Medical Center (AMC), which hosts the regional pulmonology center for COVID-19 patients and the Regional Clinical Infectious Diseases Hospital (RCIDH). The study is a selective, single-stage cross-sectional analysis. To assess the psychological reactions of medical workers, standardized questionnaires are used, including the PSM-25, GAD-7, and MFI-20. Statistical analysis of the data is conducted using the STATISTICA 10.0 software package from StatSoft, Inc., USA. An analysis of the research results indicates that medical personnel, nurses, and administrative staff in medical organizations associated with the risk of coronavirus infection are susceptible to adverse psychophysiological disorders. The study revealed that stress levels, anxiety, and asthenia in doctors and nursing staff are significantly higher compared to those in nurses and administrative personnel. Medical workers at risk of COVID- 19 clearly require support measures, as the potential for occupational infection has been definitively established. Additionally, the psychological risk is largely influenced by the nature of their work and their direct contact with the population and patients infected with the coronavirus. Senior and mid-level medical workers at the forefront of combating coronavirus infection is at a high risk of experiencing psycho-emotional and psychophysiological health issues. Doctors and nurses have been found to exhibit high levels of physical and mental asthenia, anxiety, and moderate-to-high levels of stress. Evaluating potential risk factors for psychophysiological disorders among healthcare workers not only provides an objective assessment of their health status, but also aids in the effective and rational organization of their work.

Injuries of the oral mucosa. Clinical cases

Background. Often with some infectious diseases, in addition to the typical manifestations, characteristic inflammatory changes are observed on the mucous membranes, which can imitate the course of other diseases. The purpose was to remind dentists and general practitioners about the importance of differential diagnosis of lesions of the oral mucosa in infectious and non-infectious pathologies on the example of clinical cases. Materials and methods. We conducted an empirical, descriptive study of 3 clinical cases of lesions of the oral mucosa in children who underwent inpatient treatment at the Kyiv City Children’s Clinical Infectious Hospital in 2023–2024. Results. In the first clinical case, the manifestation of type 1 diabetes was described, which was accompanied by oral candidiasis that was previously regarded as a suspicion of measles. The second clinical case demonstrates aphthous ulcers in HIV infection, which was previously mistaken for acute tonsillitis in a child. The third case described enteroviral vesicular stomatitis, which by the nature of the elements resembled chicken pox. Conclusions. Lesions of the oral mucosa can mimic the manifestations of common infectious and non-infectious diseases. Therefore, differential diagnosis of lesions of the oral mucosa is extremely important in various fields of medicine and dentistry.

European Society of Clinical Microbiology and Infectious Diseases/European Committee on infection control clinical guidelines on pre-operative decolonization and targeted prophylaxis in patients colonized by multidrug-resistant Gram-positive bacteria before surgery

ScopeThe aim of these guidelines is to provide recommendations for decolonization and perioperative antibiotic prophylaxis (PAP) in multidrug-resistant Gram-positive bacteria (MDR-GPB) adult carriers before inpatient surgery. MethodsThese European Society of Clinical Microbiology and Infectious Diseases/European Committee on Infection Control guidelines were developed following a systematic review of published studies targeting methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci, methicillin-resistant coagulase-negative Staphylococci, and pan-drug-resistant-GPB. Critical outcomes were the occurrence of surgical site infections (SSIs) caused by the colonizing MDR-GPB and SSIs-attributable mortality. Important outcomes included the occurrence of SSIs caused by any pathogen, hospital-acquired infections, all-cause mortality, and adverse events associated with the interventions, including resistance development to the agents used and the incidence of Clostridioides difficile infections. The last search of all databases was performed on 1 November 2023. The level of evidence and the strength of each recommendation were defined according to the Grading of Recommendations Assessment, Development, and Evaluation approach. Consensus of a multidisciplinary expert panel was reached for the final list of recommendations. Antimicrobial stewardship considerations were included. RecommendationsThe guideline panel reviewed the impact of decolonization, targeted PAP, and combined interventions (e.g. decolonization and targeted PAP) on the risk of SSIs and other outcomes in MDR-GPB carriers, according to the type of bacteria and type of surgery.We recommend screening for S. aureus before high-risk operations, such as cardiothoracic and orthopaedic surgery. Decolonization with intranasal mupirocin with or without a chlorhexidine bath is recommended in patients colonized with S. aureus before cardiothoracic and orthopaedic surgery and suggested in other surgeries. The addition of vancomycin to standard prophylaxis is suggested for MRSA carriers in cardiothoracic surgery, orthopaedic surgery, and neurosurgery. Combined interventions (e.g. decolonization and targeted prophylaxis) are suggested for MRSA carriers undergoing cardiothoracic and orthopaedic surgery. No recommendation could be made regarding screening, decolonization and targeted prophylaxis for vancomycin-resistant enterococci because of the lack of data. No evidence was retrieved for methicillin-resistant coagulase-negative Staphylococci and pan-drug-resistant-GPB. Careful consideration of the laboratory workload and involvement of antimicrobial stewardship and infection control teams are warranted before implementing screening procedures or performing changes in PAP policy. Future research should focus on novel decolonizing techniques, on the monitoring of resistance to decolonizing agents and PAP regimens, and on standardized combined interventions in high-quality studies.

Scientific misconduct in infectious diseases—European Society of Clinical Microbiology and Infectious Diseases survey

ObjectivesWe aimed to evaluate the prevalence and perception of scientific misconduct in infectious diseases (ID) and clinical microbiology (CM), as reported by the ID/CM community. MethodsAn anonymous online European Society of Clinical Microbiology and Infectious Diseases survey circulated among society members from October 2023 to June 2024; the questionnaire included data on participants' views on their own and their colleagues' scientific misconduct in the last 5 years. ResultsThe survey received 220 responses. Responders were 73% ID physicians, 52% men, 56% aged 35–54 years, and represented 48 countries, mainly European (126 participants). The vast majority of participants (78%) reported that they did not personally commit scientific misconduct, whereas 54% reported witnessing misconduct by colleagues in their field. The most commonly committed misconduct by both responders and their colleagues was misconduct of authorship rules, 14% and 41%, respectively. Overall, 18% reported witnessing misleading reporting and 14% reported witnessing nonaccurate reporting of conflict of interest. Nevertheless, the majority (>60%) of responders reported high confidence in the integrity of published work in the field of ID/CM. Approximately one-third of responders were not aware of the European Society of Clinical Microbiology and Infectious Diseases ethics advisory committee as an authority to which members can report misconduct. DiscussionScientific misconduct, mostly related to violation of authorship rules, seems to be common in ID/CM. Efforts to improve scientific integrity should be made to keep trust in the scientific process.

European society of clinical microbiology and infectious diseases guidelines for antimicrobial stewardship in emergency departments (endorsed by European association of hospital pharmacists)

ScopeThis European Society of Clinical Microbiology and Infectious Diseases guideline provides evidence-based recommendations to support a selection of appropriate antibiotic use practices for patients seen in the emergency department (ED) and guidance for their implementation. The topics addressed in this guideline are (a) Do biomarkers or rapid pathogen tests improve antibiotic prescribing and/or clinical outcomes? (b) Does taking blood cultures in common infectious syndromes improve antibiotic prescribing and/or clinical outcomes? (c) Does watchful waiting without antibacterial therapy or with delayed antibiotic prescribing reduce antibiotic prescribing without worsening clinical outcomes in patients with specific infectious syndromes? (d) Do structured culture follow-up programs in patients discharged from the ED with cultures pending improve antibiotic prescribing? MethodsAn expert panel was convened by European Society of Clinical Microbiology and Infectious Diseases and the guideline chair. The panel selected in consensus the four most relevant antimicrobial stewardship topics according to pre-defined relevance criteria. For each main question for the four topics, a systematic review was performed, including randomized controlled trials and observational studies. Both clinical outcomes and stewardship process outcomes related to antibiotic use were deemed relevant. The literature searches were conducted between May 2021 and March 2022. In April 2022, the panel members were formally asked to suggest additional studies that were not identified in the initial searches. Data were summarized in a meta-analysis if possible or otherwise summarized narratively. The certainty of the evidence was classified according to the Grading of Recommendations Assessment, Development and Evaluation criteria. The guideline panel reviewed the evidence per topic critically appraising the evidence and formulated recommendations through a consensus-based process. The strength of the recommendations was classified as strong or weak. To substantiate the implementation process, implementation trials or observational studies describing facilitators/barriers for implementation were identified from the same searches and were summarized narratively. RecommendationsThe recommendations on the use of biomarkers and rapid pathogen diagnostic tests focus on the initiation of antibiotics in patients admitted through the ED. Their effect on the discontinuation or de-escalation of antibiotics during hospital stay was not reported, neither was their effect on hospital infection prevention and control practices. The recommendations on watchful waiting (i.e. withholding antibiotics with some form of follow-up) focus on specific infectious syndromes for which the primary care literature was also included. The recommendations on blood cultures focus on the indication in three common infectious syndromes in the ED explicitly excluding patients with sepsis or septic shock. Most recommendations are based on very low and low certainty of evidence, leading to weak recommendations or, when no evidence was available, to best practice statements. Implementation of these recommendations needs to be adapted to the specific settings and circumstances of the ED. The scarcity of high-quality studies in the area of antimicrobial stewardship in the ED highlights the need for future research in this field.

Evaluation and management of febrile neutropenia in patients with cancer.

Febrile neutropenia is a common oncologic emergency that increases the risk for serious infection. This article reviews a joint American Society of Clinical Oncology and Infectious Diseases Society of America guideline for the evaluation and management of patients with cancer who present with fever and neutropenia. Knowledge and use of available risk assessment tools may reduce unnecessary hospitalizations, decrease inappropriate antibiotic use, and improve patient outcomes.

Healthcare-associated Diarrhea due to Clostridioides difficile in Patients Attending a Tertiary Care Teaching Hospital of North India.

Healthcare-associated diarrhea (HCAD) is diarrhea that develops at least after 3 days of hospitalization, with the most common infectious cause being Clostridioides difficile. Over the last decade, there has been a remarkable growth in the frequency and severity of C. difficile infection (CDI), making it one of the most prevalent healthcare-associated infections. This study aimed to analyze the prevalence and risk factors associated with CDI. A total of 107 patients with clinical suspicion of having HCAD were included in this study. Enzyme-linked fluorescent assay (ELFA) technique-based glutamate dehydrogenase (GDH) and toxin A/B assay were used as per the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) for diagnosing CDI. The details about associated comorbidities were retrieved from the hospital information system records. The presence of risk factors was noted. Risk factors associated with CDI were looked for. Out of the 107 stool samples received in the microbiology laboratory from patients with suspected HCAD eight (7.6%) samples were positive for CDI. The most frequent comorbidity observed in these patients was renal illness (acute or chronic kidney disease). In this study, a total of 7/8 cases were on multiple antibiotics most common being carbapenem. The 6-year prevalence of CDI observed in this study was found to be 7.6% risk factors, associated with CDI were kidney disease, diabetes mellitus, malignancy, and exposure to broad-spectrum antibiotics.

THE IMPACT OF VACCINATION STATUS ON THE CLINICAL CHARACTERISTICS OF MEASLES COURSE

Measles is a dangerous and highly contagious viral disease with a tendency to spread rapidly. The incidence of measles is cyclical with outbreaks occurring every 5-6 years and is directly related to the level of vaccination against the disease. Measles can become severe clinical course and have serious, sometimes fatal consequences. The purpose of the study is to compare the clinical course of measles depending on the vaccination status of patients. We analysed medical records of 218 patients aged 18 to 55 years who were inpatients with a diagnosis of measles at the Poltava Regional Clinical Infectious Diseases Hospital. The clinical features of measles were compared based on vaccine status using descriptive statistics methods in accordance with the analysis requirements. Comparison of the clinical course of the disease depending on vaccination status did not reveal a statistically significant difference in clinical symptoms between the groups of vaccinated and unvaccinated individuals. However, in the group of unvaccinated patients, a severe course of measles was significantly more often observed compared to those who were vaccinated (p = 0.003). The incidence of complications was studied and found to be lower in vaccinated individuals than in non-immune patients (p = 0.051), specifically pneumonia (p = 0.006). No cases of complications such as measles encephalitis and enterocolitis were recorded among vaccinated individuals. Thus, the course of the disease was characterised by typical clinical signs with a predominance of intoxication syndrome, the appearance of a typical rash, its stages, the presence of catarrhal and, less often, intestinal syndromes. It was found that vaccinated individuals had significantly less frequent severe measles, and the incidence of complications, including pneumonia, was was significantly lower than in unvaccinated patients.

Comparison of international guidelines for CT prior to lumbar puncture in patients with suspected meningitis.

To compare the performance of multiple international guidelines in selecting patients for head CT prior to lumbar puncture (LP) in suspected meningitis, focusing on identification of potential contraindications to immediate LP. Retrospective study of 196 patients with suspected meningitis presenting to an emergency department between March 2013 and March 2023 and undergoing head CT prior to LP. UK Joint Specialist Society Guidelines (UK), European Society of Clinical Microbiology and Infectious Diseases (ESCMID) and Infectious Diseases Society of America (IDSA) guidelines were evaluated by cross-referencing imaging criteria with clinical characteristics present at time of presentation. Sensitivity of each guideline for recommending neuroimaging in cases with brain shift on CT was evaluated, along with the number of normal studies and incidental or spurious findings. 2/196 (1%) patients had abnormal CTs with evidence of brain shift, while 14/196 (7%) had other abnormalities on CT without brain shift. UK, ESCMID and IDSA guidelines recommended imaging in 10%, 14% and 33% of cases respectively. All three guidelines recommended imaging pre-LP in 2/2 (100%) cases with brain shift. IDSA guidelines recommended more CT studies with normal findings (59 vs 16 and 24 for UK and ESCMID guidelines respectively) and CT abnormalities without brain shift (4 vs 1 and 2 respectively) than the other guidelines. UK, ESCMID and IDSA guidelines are all effective at identifying the small cohort of patients who benefit from a head CT prior to LP. Following the more selective UK/ESCMID guidelines limits the number of normal studies and incidental or spurious CT findings.

Evaluation of the in vitro susceptibility of clinical isolates of NDM-producing Klebsiella pneumoniae to new antibiotics included in a treatment regimen for infections.

Due to the growing resistance to routinely used antibiotics, the search for new antibiotics or their combinations with effective inhibitors against multidrug-resistant microorganisms is ongoing. In our study, we assessed the in vitro drug susceptibility of Klebsiella pneumoniae strains producing New Delhi metallo-β-lactamases (NDM) to antibiotics included in the Infectious Diseases Society of America (IDSA) and European Society of Clinical Microbiology and Infectious Diseases (ESCMID) recommendations. A total of 60 strains of NDM-producing K. pneumoniae were obtained from different patients hospitalized at the 4th Military Hospital in Wroclaw between 2019 and 2022 and subjected to drug susceptibility to selected antibiotics, including the effects of drug combinations. Among the tested antibiotics, the highest sensitivity (100%) was observed for cefiderocol, eravacycline (interpreted according to the European Committee on Antimicrobial Susceptibility Testing [EUCAST]), and tigecycline. Sensitivity to intravenous fosfomycin varied depending on the method used. Using the "strip stacking" method, determining cumulative sensitivity to ceftazidime/avibactam and aztreonam demonstrated 100% in vitro sensitivity to this combination among the tested strains. The in vitro susceptibility assessment demonstrated that, the best therapeutic option for treating infections caused by carbapenemase-producing strains seems to be a combination of ceftazidime/avibactam with aztreonam. Due to the safety of using both drugs, cost effectiveness, and the broadest indications for use among the tested antibiotics, this therapy should be the first-line treatment for carbapenemase-producing Enterobacterales infections. Nevertheless, a comprehensive evaluation of the efficacy of treating infections caused by NDM-producing K. pneumoniae strains should include not only in vitro susceptibility assessment but also an analysis of clinical cases.

Laboratory diagnosis of Clostridioides difficile infection: guidelines and status of practice in Korea

Clostridioides difficile infection (CDI) is a common healthcare-associated infection that is expected to increase with the increases in the elderly population, immunocompromised patients treated with chemotherapy and immunosuppressive drugs, antimicrobial-resistant bacteria, and invasive medical technologies. Accurate diagnosis is critical for proper treatment and management of CDI. Clinical laboratories typically use four methods to diagnose CDI: C. difficile culture, toxin detection using immunoassays, detection of glutamate dehydrogenase using immunoassays, and detection of toxin A/B gene. Each CDI diagnostic test has strengths and limitations, and varies in performance. Guidelines for CDI diagnosis have been developed by organizations that include the European Society of Clinical Microbiology and Infectious Diseases, Infectious Diseases Society of America/Society for Healthcare Epidemiology of America, and American College of Gastroenterology. Certain other countries have guidelines. In Korea, surveys on CDI diagnosis performed in 2015 and 2018 revealed a shift in CDI testing in clinical laboratories in Korea. It is necessary to develop standardized diagnostic guidelines for CDI appropriate for the Korean context.

Compliance with guideline recommendations in the management of patients with hospitalized community-acquired pneumonia.

Compliance with guidelines in the empirical treatment for community-acquired pneumonia (CAP) is very important to increase treatment success and reduce mortality. This study aimed to determine compliance with guideline recommendations for CAP and define the role of the clinical pharmacist (CP). Patients diagnosed with CAP were evaluated retrospectively between January 2018 and January 2020 and prospectively between February 2020 and February 2021. Compliance with guidelines was evaluated according to the local, national (Turkish Thoracic Society), and international (American Thoracic Society and Infectious Disease Society of America, European Society of Clinical Microbiology and Infectious Diseases) guidelines. A total of 751 patients (423 in the retrospective and 328 in the prospective period) were included. It was determined that the 30-day mortality and length of stay were higher in patients who were not treated according to the guidelines. The compliance for empirical treatments was 16.3%-59.1% and 7.8%-30.1% in retrospective and prospective periods, respectively. During the prospective period, a total of 603 recommendations were made by CP, and 578 (95.9%) were accepted and implemented. In the prospective period, treatment duration was shortened, inappropriate fluoroquinolone use was decreased, the switch to oral treatment was increased, and the number of potential drug-drug interactions was decreased (p < 0.001). Compliance with guidelines is essential to be improved to reduce mortality, shorten the length of stay, determine the appropriate antimicrobial duration, and reduce the use of fluoroquinolones and broad-spectrum antibiotics unless necessary. CP intervention contributes to the rational selection of antimicrobials, limiting drug-drug interactions, avoiding toxicities, and compliance with guidelines.

Discrepancy between IDSA and ESGBOR in Lyme disease: Individual participant meta-analysis in Türkiye.

The evidence on the prevalence of Lyme borreliosis (LB) is limited, but there is a suspicion of overdiagnosis of LB in recent years. We reviewed the LB diagnosis and treatment-related data in Türkiye, based on the Infectious Diseases Society of America (IDSA) 2020 and European Society of Clinical Microbiology and Infectious Diseases Study Group for Lyme Borreliosis (ESGBOR) 2018 guidelines. By detecting the disagreements between these two, we outlined the areas to be improved for future guidelines. We performed a literature search according to the PRISMA guidelines in PubMed, Ovid-Medline, Web of Science, Turkish Medline, Scopus, CINAHL, ULAKBIM TR Index, Google Scholar and Cochrane Library databases. We included the published cases in a database and evaluated according to IDSA and ESGBOR guidelines. We outlined the reasons for misdiagnoses and inappropriate uses of antibiotics. We included 42 relevant studies with 84 LB cases reported from Türkiye between 1990 and December 2022. Among 84 cases, the most common clinical findings were nervous system findings (n = 37, 44.0%), erythema migrans (n = 29, 34.5%) and ophthalmologic findings (n = 15, 17.9%). The IDSA 2020 and ESGBOR 2018 guidelines agreed on the diagnosis of 71 (84.5%) cases; there was an agreement that 31 cases (36.9%) were misdiagnosed and 40 cases (47.6%) were correctly diagnosed, and there was disagreement for 13 cases (15.5%). Serum immunoglobulin M (IgM), IgG measurements by ELISA and western blot were widely performed, and they were effective in definitive diagnosis merely when used according to guidelines. Inappropriate use of antibiotics was detected in 42 (50.0%) of cases which were classified in the following categories: incorrect LB diagnosis, inappropriate choice of antibiotic, inappropriate route of drug administration and prolonged antibiotic treatment. Overdiagnosis and non-adherence to guidelines is a common problem. The discordance between seroprevalence and clinical studies necessitates a consensus over the best clinical approach.

Medical Research Genres in the English Academic Discourse

Introduction. The research article in English has recently been under scrutiny by theoretical and applied linguists. The understanding of research article is heterogeneous: it can be defined as a scientific manuscript, an independent text type or a separate genre. In Russian academic discourse the concept of the research article usually implies a scientific publication with the definite word count which is less than a monograph. However, this broad definition comprises a variety of heterogeneous genres. The English academic discourse, on the contrary, specifies research genres manifested in Research, Review, Editorial, Commentary, Clinical Case Report and other text names. Additionally, these research genres can vary according to the scientific discipline. The objective of this paper is to identify and classify academic research genres in medical discourse.Methodology and sources. The research corpus was collected from the original highimpact open-access medical journals, i.e., Lancet, New England Journal of Medicine, British Medical Journal, Clinical Infectious Diseases, Journal of Clinical Investigation, Brain, Pediatrics, Diabetes, Heart, Journal of Neuroscience. The research procedure involved contextual, semantic and comparative analysis of the journal requirements on the article type and content presented in typical sections About the Journal, Authors Guidelines and Table of Contents.Results and discussion. The analysis has led to the development of differential parameters for further research genres classification. The findings have shown that a variety of research papers under different names can be classified as a system of research genres in the academic discourse represented by medical research publications. We have also found distinct correlations between medical journal requirements and linguistic characteristics of medical research genres.Conclusion. The academic medical discourse functions in a wide spectrum of article types, which can be classified as medical research genres according to discourse parameters.

Current management of SARS-CoV-2 infection in solid organ transplant recipients: Experience derived from an ESGICH-ESOT survey.

Solid organ transplant (SOT) recipients have a poorer SARS-CoV-2 vaccine response and higher risk for COVID-19-associated complications. However, there is no consensus on the current management of COVID-19 and data on persistent COVID-19 rates in SOT recipients are lacking. An electronic survey concerning the management of COVID-19 in SOT recipients was distributed among all members of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Study Group for Infections in Compromised Hosts (ESGICH) and of the European Society for Organ Transplantation (ESOT). Four major sections were covered: prevention, early COVID-19, late COVID-19, and persistent COVID-19. We developed a structured questionnaire including eight multiple-choice questions with branching logic in case of positive answers and three open-ended questions related to clinical practice. Questions were asked separately for lung and non-lung transplantation. Thirty-two physicians from 24 different centers participated. Most answers (n = 30) were provided by European physicians. Thirty of 32 (93.75%) physicians managed non-lung transplant recipients and 12 of 32 (33.3%) lung transplant recipients. There was a huge variability in practice regarding the treatment of COVID-19, and particularly noticeable when considering lung and non-lung transplant recipients. Main discordances included the use of nirmatrelvir alone or in combination therapy for early COVID-19, the use of immunomodulatory drugs other than steroids for late COVID-19, and the need for treating asymptomatic viral shedding in persistent COVID-19. There was more similarity in terms of prophylaxis recommendations. Despite a low number of respondents, this survey shows that there are many differences on how experts manage SARS-CoV-2 infections in SOT recipients.

Personalized corticosteroid treatment of patients with severe new coronavirus infection complicated by pneumonia: a prospective comparative study

INTRODUCTION: A new coronavirus infection caused by the SARS-CoV-2 coronavirus and the associated disease COVID-19 is accompanied by a high incidence of acute respiratory distress syndrome (ARDS) and pneumonia with respiratory failure. Corticosteroids are a therapeutic treatment option. OBJECTIVE: To determine the advantage of personalized corticosteroid dosing to reduce inflammation in pneumonia in patients with comorbid diseases. MATERIALS AND METHODS: A prospective comparative study was conducted among adult patients in the Republican Clinical Infectious Hospital and the Clinical Emergency Hospital (Ufa, Republic of Bashkortostan) from May 2020 to May 2021. Patients were divided into two groups: personalized corticosteroid administration in accordance with the level of the inflammation biomarker C-reactive protein (CRP) (n = 30) compared with conventional therapy (n = 28). Measurements of CRP levels in blood samples were carried out at the time of hospitalization and then daily during the first 5 days of treatment. RESULTS: The intervention group had fewer days of respiratory support (9.4 [6.2–15.6] vs. 14.3 [7.1–21.4]; p = 0.003) and no differences in cumulative outcome (persistent dependence of respiratory support or death) and the incidence of nosocomial infection compared with the control group. Daily distribution of the biomarker CRP showed significantly lower levels on 2–4 days of treatment in the intervention group compared with the control group. CONCLUSIONS: In critically ill patients with pneumonia caused by COVID-19, and comorbid diseases, a personalized approach to the corticosteroids prescribing slightly reduced the frequency of treatment ineffectiveness and statistically significantly reduced the duration of respiratory support.
