ABSTRACT
Community-acquired pneumonia is a potentially serious infection in children with high morbidity rate, risk of severe course and unfavorable outcomes. Specialists have noted the increased incidence of the destructive forms in the recent years. Aim. To present a clinical case of destructive pneumonia in a 1 year 2 month old child, hospitalized in the State Budgetary Healthcare Institution "Children's City Clinical Hospital of St. Vladimir Moscow Healthcare Department", and analyze it in terms of current understanding on the disease pathogenesis. Conclusion. During COVID-19 (COronaVIrus Disease 2019) pandemic, pulmonologists and pediatric surgeons encountered an unconventional course of destructive pneumonia. A large number of studies of pathophysiological processes in acute viral interstitial pneumonias have recently allowed to expand our understanding of the role of coagulation system. At the same time, new questions arose concerning the clinical course and development of the pathological infectious process.Copyright © Zaytseva O.V. et al., 2023.
ABSTRACT
Background: X-Linked Moesin-Associated Immune Deficiency (X-MAID) is a rare severe combined immunodeficiency (SCID) subtype that can present at any age due to its variability. Depending on severity, patients demonstrate failure to thrive, recurrent bacterial and viral infections, and increased susceptibility to varicella zoster. It has been characterized by marked lymphopenia with hypogammaglobulinemia and impaired T-cell migration and proliferation. Case Presentation: This is a report of a Cuban 7-year-old male with poor weight gain and facial dysmorphia. He had a history of recurrent bacterial gastrointestinal infections and pneumonia beginning at 4 months of age. He additionally had 4-6 upper respiratory tract and ear infections annually. While still living in Cuba, he was admitted for a profound EBV infection in the setting of significant leukopenia. A bone marrow biopsy confirmed no malignancy. After he moved to the United States, his laboratory work-up revealed marked leukopenia with low absolute neutrophil and lymphocyte count with low T and B cells, very low immunoglobulin levels IgG, IgA, and IgM, and poor vaccination responses to streptococcus pneumonia, varicella zoster, and SARS-CoV-2. Genetic testing revealed a missense pathogenic variant c.511C>T (p.Arg171Trp) in the moesin (MSN) gene associated with X-MAID. He was managed with Bactrim and acyclovir prophylaxis, and immunoglobulin replacement therapy, and considered for hematopoietic stem cell transplantation. Discussion(s): Diagnosis of X-MAID should be considered in patients with recurrent infections and profound lymphopenia. As with SCID, early diagnosis and intervention is of utmost importance to prevent morbidity and mortality. This case demonstrates the importance of genetic testing in identifying this disease as it may prompt an immunologist to consider HSCT if conservative management is suboptimal. In the current literature, HSCT appears promising, but the long-term outcomes have yet to be described.Copyright © 2023 Elsevier Inc.
ABSTRACT
Background/Objectives: The broad spectrum of clinical manifestations from SARS-COV-2 infection and observed risk factors for severe disease highlight the importance of understanding molecular mechanisms underlying SARS-CoV-2 associated disease pathogenesis. Research studies have identified a large number of host proteins that play roles in viral entry, innate immune response, or immune signalling during infection. The ability to interrogate subsets of these genes simultaneously within SARSCOV-2 infected samples is critical to understanding how their expression contribute to phenotypic variability of the disease caused by the pathogen. Method(s): 30 Nasopharyngeal swab were obtained and included SARS-CoV-2 infected and control samples. RNA was extracted, reverse transcribed and loaded onto flexible TaqMan array panels designed specifically for targeting the most cited genes related to SARS-COV-2 entry and restriction factors as well as cytokines, chemokines, and growth factors involved in the pathogenesis. Result(s): Our data indicated that not only were the levels of several of these host factors differentially modulated between the two study groups, but also that SARS-CoV-2 infected subjects presented with greater frequency of several important inflammatory cytokines and chemokines such as CCL2, CCL3, IFNG, entry receptors such as ACE2, TMRPS11A, and host restriction factors including LY6E and ZBP1. Conclusion(s): TaqMan array plates provide a fast, midthroughput solution to determine the levels of several virus and host-associated factors in various cell types and add to our understanding of how the pathogenesis may vary depending on gender, age, infection site etc.
ABSTRACT
Submission content Introduction: An unusual case of a very young patient without previously known cardiac disease presenting with severe left ventricular failure, detected by a point of care echocardiogram. Main Body: A 34 year old previously well man was brought to hospital after seeing his general practitioner with one month of progressive shortness of breath on exertion. This began around the time the patient received his second covid-19 vaccination. He was sleeping in a chair as he was unable to lie flat. Abnormal observations led the GP to call an ambulance. In the emergency department, the patient required oxygen 5L/min to maintain SpO2 >94%, but he was not in respiratory distress at rest. Blood pressure was 92/53mmHg, mean 67mmHg. Point of care testing for COVID-19 was negative. He was alert, with warm peripheries. Lactate was 1.0mmol/L and he was producing more than 0.5ml/kg/hr of urine. There was no ankle swelling. ECG showed sinus tachycardia. He underwent CT pulmonary angiography which demonstrated no pulmonary embolus, but there was bilateral pulmonary edema. Troponin was 17ng/l, BNP was 2700pg/ml. Furosemide 40mg was given intravenously by the general medical team. Critical care outreach asked for an urgent intensivist review given the highly unusual diagnosis of pulmonary edema in a man of this age. An immediate FUSIC Heart scan identified a dilated left ventricle with end diastolic diameter 7cm and severe global systolic impairment. The right ventricle was not severely impaired, with TAPSE 18mm. There was no significant pericardial effusion. Multiple B lines and trace pulmonary effusions were identified at the lung bases. The patient was urgently discussed with the regional cardiac unit in case of further deterioration, basic images were shared via a cloud system. A potential diagnosis of vaccination-associated myocarditis was considered,1 but in view of the low troponin, the presentation was felt most likely to represent decompensated chronic dilated cardiomyopathy. The patient disclosed a family history of early cardiac death in males. Aggressive diuresis was commenced. The patient was admitted to a monitored bed given the potential risk of arrhythmia or further haemodynamic deterioration. Advice was given that in the event of worsening hypotension, fluids should not be administered but the cardiac centre should be contacted immediately. Formal echocardiography confirmed the POCUS findings, with ejection fraction <35%. He was initiated on ACE inhibitors and beta adrenergic blockade. His symptoms improved and he was able to return home and to work, and is currently undergoing further investigations to establish the etiology of his condition. Conclusion(s): Early echocardiography provided early evidence of a cardiac cause for the patient's presentation and highlighted the severity of the underlying pathology. This directed early aggressive diuresis and safety-netting by virtue of discussion with a tertiary cardiac centre whilst it was established whether this was an acute or decompensated chronic pathology. Ultrasound findings: PLAX, PSAX and A4Ch views demonstrating a severely dilated (7cm end diastolic diameter) left ventricle with global severe systolic impairment.
ABSTRACT
Introduction: Medical students receive relatively little exposure to intensive care medicine throughout their undergraduate training in comparison to other specialties. The COVID-19 pandemic further hindered students' exposure with entrance to intensive care units (ICU) limited to conserve personal protective equipment (PPE) and reduce the risk of virus spread. To address this problem, this study explored the use of assisted reality technology to create a smart classroom whereby medical students can experience intensive care medicine with the COVID-19 risks mitigated. There is existing literature describing the use of live streaming ward rounds using wearable technology to teach medical students, however, we believe this is the first time assisted reality technology has been harnessed to develop a teaching curriculum on intensive care.1 Objectives: This study aimed to assess the feasibility of using a wearable headset with assisted reality technology to live stream intensive care teaching to remotely based medical students. Method(s): Three intensive care teaching sessions were live streamed to three groups of medical students using the AMA XpertEye wearable glasses. The teaching session focused on the intensive care bed space and equipment as well as the assessment of a critically unwell intensive care patient. Two educators were required to facilitate the optimum learning environment. One educator wore the assisted reality technology glasses on the ICU whilst the other educator remained with the students to facilitate group discussion. The educators had the means to communicate via inbuilt technology on the glasses. Feedback from students was collected using the evaluation of technology-enhanced learning materials (ETELM).2 Results: The response rate for the ETELM survey was 100%. Students strongly agreed that the session was well organised, relevant and that the navigation of technology-based components was logical and efficient. 'There was a strong instructor presence and personal touch to the session' returned the strongest positive response. 'This session will change my practice' received the most varied response from students, potentially due to their stage in undergraduate training and distance from actual clinical practice. Students strongly disagreed that their learning was affected by technology issues. Educators reported problems with securing a patient appropriate to be involved alongside the busy clinical demands of the ICU. Facilitation by trained educators was crucial to ensure the teaching sessions were high quality. Conclusion(s): The use of smart classrooms on intensive care using assisted reality technology was very well received by medical students and educators. The main limitations included the necessity to balance the delivery of teaching alongside the clinical demands of the unit, however this is arguably the case with most forms of clinical teaching. There is the potential to continue using smart classrooms in the post-pandemic period, as they provide an open and safe platform for students to explore intensive care medicine and to ask questions that they may feel less able to raise in the busy clinical environment.
ABSTRACT
Objectives: Data about COVID-19 patients treated with veno-arterial-ECMO (VA-ECMO) is limited. Reported survival rates range from 27.9% to 77.8%, depending on VA-ECMO indication. A subgroup of patients suffers from circulatory failure due to a COVID-19 associated hyperinflammatory state (CovHI). In these patients, differentiation between inflammation and sepsis is difficult but important. In this retrospective case series, differential diagnoses of COVID-19 associated refractory circulatory failure and survival rates in different indications for VA-ECMO are investigated. Method(s): Retrospective analysis of 28 consecutive COVID-19 patients requiring VA-ECMO at the University Hospital Regensburg between March 2020 and May 2022. Specific treatment for COVID-19 was in accordance with respective guidelines. Mycotic infections were either invasive or met current definitions of COVID19-associated-pulmonary aspergillosis. Result(s): At VA-ECMO initiation, median age was 57.3 years (IQR: 51.4 - 61.8), SOFA score 16 (IQR: 13 - 17) and norepinephrine dosing 0.53mug/kg/min (IQR: 0.32 - 0.78). Virus-variants were: 61% wild-type, 14% Alpha, 18% Delta and 7% Omicron. Survival to hospital discharge was 39%. 17 patients were primarily supported with VA-ECMO only (survival 42%), 3 patients were switched from VV to VA-ECMO (survival 0%), and 8 patients were converted from VA to VAV or VV-ECMO (survival 50%). Indications for VA-ECMO support were pulmonary embolism (PE) (n=5, survival 80%), right heart failure due to secondary pulmonary hypertension (n=5, survival 20%), cardiac arrest (n=4, survival 25%), acute left heart failure (ALHF) (n=11, survival 36%) and refractory vasoplegia (n=3, survival 0%). Inflammatory markers at VA-ECMO initiation were higher in patients with ALHF or vasoplegia;in these patients a higher rate of invasive fungal infections (10/14, 71% vs. 4/14, 29%;p=0.023) compared to the other patients was found. Conclusion(s): Survival on VA-ECMO in COVID-19 depends on VA-ECMO indication, which should be considered in further studies and clinical decisions making. Circulatory failure due to vasoplegia should be considered very carefully as indication for VA-ECMO. A high rate of mycotic infections mandates an intense microbiological workup of these patients and must be considered as an important differential diagnosis to CovHI.
ABSTRACT
Background It is a challenge for pharmacy courses worldwide to combine theoretical knowledge with practical skills to equip students for their future practice. Computer-based simulation offers a way of building a bridge between theory and practice. In recent years, digital simulation has expanded rapidly as a new technique of virtual learning. The digital platform ''Pharmacy Simulator'' proposes computer-based encounters with virtual patients to train clinical and communication skills in a community pharmacy setting. However, during the COVID-19 pandemic, while students were digitally resilient and endured the endless challenges of online lectures, many were dealing with Zoom and screen fatigue. Purpose To investigate pharmacy students' acceptance of Pharmacy Simulator before and during a pandemic situation. This focuses on students' self-assessment and confidence in counselling after playing the scenarios on Pharmacy Simulator. Method Two cohorts of Master of Pharmacy students at The University of Western Australia played two scenarios on Pharmacy Simulator in 2019 (anaphylaxis and salbutamol) and 2021 (anaphylaxis and vaccination). A mixed-method analysis was performed with data from (i) qualitative semi-structured interviews carried out in 2019 pertaining to participants' acceptance of Pharmacy Simulator and in 2021 (ii) a questionnaire with 25 items derived from the interviews. The interviews were transcribed verbatim into electronic format with the data management assistance MAXQDA and analyzed inductively using the Framework Method. Questionnaire responses were analyzed in Microsoft Excel using descriptive statistics. Openended questions were evaluated inductively. Findings Data were collected from 20 interviews and 31 answered questionnaires. In 2019, participants reported that Pharmacy Simulator was a fun, engaging, and straightforward learning tool and, therefore, user-friendly. They reported the feedback at the end of the session to be most valuable. The platform was perceived to fill the gap between the theory from lectures and community pharmacy practice. In 2021, participants ''agreed'' (median: 4, on a 5-point Likert scale) with seven statements about Pharmacy Simulator's usability, such as it being a helpful tool for acquiring new knowledge. Participants' confidence in counselling regarding the scenario topics improved. One participant stated, ''It taught me more through trial and error''. Conclusion Pharmacy students reported similar acceptance levels of Pharmacy Simulator before and during the COVID-19 pandemic. The use of simulation during virtual patient encounters seems to facilitate the transfer from theory to practice, independently of learning conditions that were predominantly screen-based.
ABSTRACT
Smoking is a significant social problem threatening the population's health, especially during the coronavirus pandemic. Due to the problem's urgency, we present a clinical case of SARS-CoV-2 infection in a patient with 10 years of smoking and concomitant chronic obstructive pulmonary disease (chronic bronchitis and peribronchial pneumosclerosis). Patient L.K., 42 years old, on 13.10.2022, was hospitalized for several hours at the Emergency Hospital of the Ministry of Health of Chuvashia (Cheboksary) with a severe new coronavirus infection. Secondary diagnosis: Chronic obstructive pulmonary disease Case history: for about two to three weeks, the patient noted an increase in body temperature to 37.2-37.4 degreeC and a cough. He has smoked for about 10 years, 1 pack per day. Computed tomography showed signs of bilateral COVID-associated pneumonitis, alveolitis with 85% involvement and consolidation sites, signs of chronic bronchitis, and peribronchial pneumosclerosis. The diagnosis of COVID-19 was confirmed by a polymerase chain reaction in a nasopharyngeal smear. The NEWS2 score was 9. After the treatment started, the patient died. Histological examination showed perivascular sclerosis, peribronchial pneumosclerosis, atrophic changes in the ciliated epithelium, and structural and functional alteration of the bronchial mucosa. In addition, areas of hemorrhage and inflammatory infiltrate in the bronchial wall were found. Coronavirus is known not to cause bronchitis but bronchiolitis. In the presented case, the patient showed signs of transition of bronchitis to the acute stage. Therefore, it can be assumed that the coronavirus acts as a complicating factor. In addition to the described changes, signs of viral interstitial pneumonia, pulmonary edema, and early development of acute respiratory distress syndrome were identified.Copyright © 2023, Media Sphera Publishing Group.

ABSTRACT
The aim of the study is to describe a case of COVID-19 and myocardial infarction in an elderly patient. Material and methods. The analysis of medical documentation (outpatient card of the patient, medical history, postmortem report) was carried out. Studied macro- and micropreparations (staining with hematoxylin and eosin). Results. A 67-year-old patient, from 23.04.2020 to 26.04.2020, was hospitalized with a diagnosis of suspected coronavirus infection (COVID-19). On the background of the treatment, the patient's biological death occurred (26.04.2020). The sectional study revealed signs of bilateral total hemorrhagic pneumonia. The signs of acute transmural myocardial infarction of the anterior wall of the left ventricle were determined. Posthumously, SARS-CoV-2 RNA was detected in the lung tissue by nucleic acid amplification. In the described clinical case, a patient with concomitant cardiovascular diseases, such as arterial hypertension, coronary heart disease, developed complications against the background of COVID-19: hemorrhagic pneumonia and myocardial infarction with a fatal outcome.Copyright © Infectious Diseases: News, Opinions, Training.
ABSTRACT
Objectives: Varicella is common infectious disease mainly in childhood, usually is a mild, self-limited illness and complications are usually rare. The incubation period for this disease is generally 14- 16 days but may vary from 7 to 21 days. Varicella in the adults with comorbidities or immunosuppressed children may be severe and prolonged with complications. Method(s): A case report of a 6-year-old girl hospitalized for new-onset manifestations of disseminated vesicular exanthema, the manifestations of which occurred mainly on the chest, back, capillitium, oral cavity, and genital area. The child was suffering from abdominal, knee and lumbosacral pain at that time. The patient's history revealed that 10 days prior to the cutaneous manifestations, she had influenza with bronchopneumonia requiring oxygen therapy, steroids and antibiotics. Result(s): The condition progressed within 48 h, complicated by the development of multi-organ failure, coagulopathy with the development of disseminated intravascular coagulopathy over the course of antiviral, antibiotic and antifungal therapy. Laboratory parameters included high elevation of C-reactive protein, il-6, leukocytosis, neutrophilia and highly elevated liver enzymes. Varicella infection was confirmed by detection of herpes zoster virus - polymerase chain reaction (PCR) from vesicles. The patient received intravenous immunoglobulin therapy at a dose of 2 g/L and fresh frozen plasma, thrombocyte concentrate. The girl was intubated with analogization. Laboratory parameters subsequently revealed high anti CoV-2 positivity, high CoV-2 IgG positivity and negative CoV-2 IgM. The patient's condition did not preclude the course of multisystem inflammatory syndrome in children (MIS-C) corticosteroids were added to the treatment at a dose of 1 mg/kg weight. Patient's condition stabilized after 1 month. Discussion(s): Our case report presents an example of fulminant complicated life-threatening course of varicella. Even in common respiratory infections, we must think about the risk and consequences of coinfections and post-infectious complications such as in our case especially influenza and COVID-19.
ABSTRACT
Objectives: Cases of fulminant myocarditis after mRNA COVID-19 vaccination have been reported. The most severe may need venoarterial extracorporeal membrane oxygenation (V-A ECMO) support. Here we report two cases successfully rescued with V-A ECMO. Method(s): We included all the cases supported with V-A ECMO for refractory cardiogenic shock due to myocarditis secondary to a mRNA SARS-COV2 vaccine in the high-volume adult ECMO Program in Vall Hebron University Hospital since January 2020. Result(s): We identified two cases (table). One of them was admitted for out-of-hospital cardiac arrest. In both, a peripheral V-A ECMO was implanted in the cath lab. An intra-aortic balloon pump was needed in one case for left ventricle unloading. Support could be successfully withdrawn in a mean of five days. No major bleeding or thrombosis complications occurred. Definite microscopic diagnosis could be reached in one case (Image, 3). Treatment was the same, using 1000mg of methylprednisolone/day for 3 days. A cardiac magnetic resonance 10 days after admission showed a significant improvement in systolic function and diffuse oedema and subepicardial contrast intake in different segments (Image, 1-2). Both patients were discharged fully recovered. Conclusion(s): V-A ECMO should be established in cases of COVID-19 vaccine-associated myocarditis with refractory cardiogenic shock during the acute phase. (Table Presented).
ABSTRACT
Objectives: Acne is a leading skin problem in adolescents. After the end of COVID-19 pandemic, with the gradual transition to the routine life, we started to encounter more severe forms of acne in the last 6-month than we had seen before in the 10 year period of our Paediatric Dermatology outpatient clinic. Method(s): We evaluated the demographic and clinical characteristics, COVID infection and vaccination status, and treatment of patients who were treated at our Paediatric Dermatology outpatient clinic in the last 6 months due to severe acne. Result(s): One of our patients had acne fulminans, and four patients had acne conglobata. The common features of these patients presenting with severe acne were that they were young boys aged 15- 16 years, medium height, normal weight, and skin type 3-4. All patients had a family history of acne in their parents. They had no known comorbidities, additional treatment, history of nutritional supplement use, or accompanying arthralgia or arthritis. Four patients were initially treated with isotretinoin for severe acne, developed acne conglobata, and one developed acne fulminans during the follow-up period. Dapsone therapy was initiated in all patients according to the severity of the lesions, and adalimumab was administered to acne fulminans. Discussion(s): The frequent occurrence of severe forms of acne after the pandemic raises the question of whether COVID-19 infection or vaccination may play a role in its aetiology. Cases of mask-related acne exacerbation during COVID-19 have been well-described in the literature. However, there are no data on the effects of COVID-19 vaccination or infection on the development of severe acne. In this report, we present cases of adolescent patients with severe acne to investigate the possible reasons for the increasing number of severe acne cases presenting to our outpatient clinic during the postpandemic period.
ABSTRACT
Background/Objectives: Li-Fraumeni Syndrome (LFS) is a rare hereditary cancer predisposition syndrome characterized by high lifetime risks for multiple primary malignancies. Although most individuals with LFS inherit a pathogenic TP53 variant from a parent, approximately 20% have de novo variants with no suggestive family cancer history. This may result in an LFS experience distinct from individuals with affected relatives. This multi-case study report examines the unique psychosocial experiences of three young adults with de novo TP53 variants. Method(s): The National Cancer Institute's LFS study (NCT01443468) recruited adolescents and young adults (AYAs;aged 15-39 years) with LFS for qualitative interviews. Three participants had a de novo TP53 variant and a personal cancer history. An interprofessional team analyzed interview data using extended case study and narrative methods. Result(s): De novo participants lacked familiarity with LFS to situate a cancer diagnosis, interpret genetic test results, or adjust to chronic cancer risk. Communicating with and receiving support from family was challenged by their lack of common experience. De novo participants experienced socioemotional isolation, which was amplified during the COVID-19 pandemic. To cope, they sought support in online rare disease communities or through mental health providers. Conclusion(s): Individuals with de novo variants may lack familial guides and familiar providers to address disease management and uncertainty. Specialty health and mental health providers may support de novo patients across hereditary cancer syndromes by validating their uncertainties and connecting them with diseasespecific patient advocacy groups that support adjustment to chronic cancer risk.
ABSTRACT
The cavernous sinus is one of the dural venous sinuses which plays an important role in venous outflow from the brain and eye sockets and in the regulation of intracranial circulation. We report a case of septic cavernous sinus thrombosis in a female patient with COVID-19. The disease often results in alterations of blood rheology, thrombosis in different organs, and septic complications. This article aims to raise awareness of healthcare professionals about the characteristics of COVID-19 that might cause septic cavernous sinus thrombosis in patients with severe comorbidities. Laboratory testing revealed severe comorbidities, including diabetes mellitus and liver cirrhosis caused by hepatitis C. They manifested with an impaired protein production in the liver and coagulation disorders. Systemic effects of SARS-CoV-2 on the vascular endothelium aggravated preexisting coagulation disorders and led to hemorrhage into retrobulbar tissue and clinical signs of septic cavernous sinus thrombosis, including swelling of the eyelids, bilateral exophthalmos, and ophthalmoplegia, followed by necrosis of the facial skin.Copyright © 2022, Dynasty Publishing House.

ABSTRACT
Objectives: We present a case report of medical intensivist driven ECMO program using ECMO as a pre-procedural tool to maintain oxygenation in a patient with critical tracheal stenosis during tracheostomy placement. Method(s): VV ECMO is primarily used to support patients when mechanical ventilation is unable to provide adequate gas exchange. Alternatively, it has been used pre-procedurally when intubation is required in anticipation of a difficult airway. Described here is the first intensivist preformed awake VV ECMO cannulation to facilitate tracheostomy in a patient with severe tracheal stenosis. Result(s): The patient is a 41-year-old female with the relevant background of COVID19 pneumonia status post tracheostomy and subsequently decannulated after prolonged intubation and ICU stay. As a result, the patient developed symptomatic tracheal stenosis and presented two years after her ICU stay for scheduled bronchoscopy and balloon dilation. However, the patient developed worsening stridor and shortness of breath requiring heliox and BPAP. After multidisciplinary discussion between the critical care team ENT teams, the decision was made to cannulate for VV ECMO as a pre-procedural maneuver to allow for oxygenation during open tracheostomy in the OR. Dexmedetomidine and local anesthesia were used for the procedure with the patient sitting at 30 degrees on non-invasive ventilation and heliox. The patient was cannulated with a 21F right internal jugular return cannula and 25F right common femoral drainage cannula by medical intensivists in the intensive care unit using ultrasound guidance. The patient went for operative tracheostomy the next day and was subsequently decannulated from ECMO the following day without complication. She was discharged home on trach collar. Conclusion(s): Intensivist performed ECMO cannulation has been shown to be safe and effective. We anticipate the indications and use will continue to expand. This case is an example that intensivist driven preprocedural ECMO is a viable extension of that practice.
ABSTRACT
Background: People living with cancer are reported to be at increased risk of hospitalization and death following infection with acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This is proposed to be dependent on a combination of intrinsic patient and cancer factors such as cancer subtype, and emerging SARS-CoV-2 variants with differing pathogenicity. However, COVID-19 phenotype evolution across the pandemic from 2020 has not yet been systematically evaluated in cancer patients. Method(s): This study is a population-scale real-world evaluation of Coronavirus outcomes in the United Kingdom for cancer patients from 1st November 2020-31st August 2022. The cancer cohort comprises individuals from Public Health England's national cancer dataset, excluding individuals less than 18 years old. Case-outcome rates, including hospitalization, intensive care and casefatality rates were used to assess the evolution in disease phenotype of COVID-19 in cancer patients. Multivariable logistic regression models were fitted to compare risk of Coronavirus outcomes in the cancer cohort relative to the non-cancer population during the Omicron wave in 2022. Result(s): The cancer cohort comprised of 198,819 positive SARS-CoV-2 tests from 127,322 individual infections. Coronavirus case-outcome rates were evaluated by reference to 18,188,573 positive tests from 15,801,004 individual infections in the non-cancer population. From 2020 to 2022, the SARS-CoV-2 disease phenotype became less severe in both patients with cancer and the non-cancer population, though cancer patients remain at higher risk. In 2022, the relative risk of Coronavirus hospital admission, inpatient hospitalization, intensive care admission and mortality in cancer patients was 3.02x, 2.10x, 2.53x and 2.54x compared to the non-cancer population following multivariable adjustment, respectively. Higher risk of hospital admission and inpatient hospitalization were associated with receipt of B/T cell antibody and/or targeted therapy which also corresponded with an increased risk of Coronavirus mortality. Conclusion(s): The disease phenotype of SARS-CoV-2 in cancer patients in 2022 has evolved significantly from the disease phenotype in 2020. Direct effects of the virus in terms of SARS-CoV-2 hospitalization, intensive care and case fatality rates have fallen significantly over time. However, relative to the general population, people living with cancer and hematological malignancies remain at elevated risk. In order to mitigate the indirect effects of the SARS-CoV-2 pandemic in terms of disruption to cancer care, there should be increased focus on preventative measures. Used in conjunction with vaccination and early treatment programs, this will maximize quality of life for those with cancer during the ongoing pandemic and ensure the best cancer outcomes.
ABSTRACT
Case history: We present the case of a 31-year-old Hispanic male with history of recurrent bronchiectasis, invasive aspergillosis, and severe persistent asthma, who is now status post lung transplant for end-stage lung disease. He initially presented at 7 years of age with diarrhea, failure to thrive, and nearly absent immunoglobulin levels (IgG < 33 mg/dL, IgA < 7 mg/dL, IgM = 11 mg/dL, IgE = 4 IU/dL) necessitating IVIG treatment. Small intestinal biopsy showed villous atrophy consistent with autoimmune enteropathy. Sweat chloride was reported as indeterminate (44 me/dL). Initial WBC, platelet, and T- and NK-cell counts were within normal range, and B-cell count and percentage were borderline low. Most recently, he was found to have increased immature B-cell count (CD21low), decreased memory B-cells, and poor pneumococcal vaccine antibody response. Patient has been hospitalized numerous times with increasingly severe bronchiectasis, pneumonitis, and COVID-19 infections twice despite vaccination, leading to respiratory failure and lung transplantation. Family history is negative for immune deficiency and lung diseases. Discussion(s): Of these 3 VUSs (see the table), the one in IRF2BP2 has the most pathogenic potential due to its autosomal dominant inheritance, its location in a conserved domain (Ring), and previous case reports of pathogenic variants at the same or adjacent alleles 1-3. Baxter et al reported a de novo truncating mutation in IRF2BP2 at codon 536 (c.1606CinsTTT), which is similar to our patient's mutation. This patient was noted to have an IPEX-like presentation, with chronic diarrhea, hypogammaglobulinemia, and recurrent infections. Variant Functional Prediction Score for our variant predicts a potentially high damage effect. There are 2 other case reports of heterozygous mutations in loci adjacent to this allele;one (c.1652G>A)2 with a similar clinical phenotype to our patient and the other (C.625-665 del)3 with primarily inflammatory features and few infections. Impact: This case highlights a variant in IRF2BP2 associated with severe hypogammaglobulinemia, recurrent pulmonary infections, and autoimmune enteropathy.

ABSTRACT
Introduction: Macrophage activation syndrome (MAS) is a severe hyper inflammatory condition caused by the over-activation and proliferation of T cells, NK cells and macrophages. It is often associated with complications of rheumatic/immune diseases. We present a case of a 15-year-old female who experiences recurrent episodes of MAS without any known definitive underlying etiology. Case Presentation: A 15-year-old previously healthy female developed fatigue, fevers, myalgia, chest pain, splenomegaly and lymphadenopathy 10 days after receiving her first Pfizer COVID-19 vaccine. Her symptoms recurred 10 days after receiving the second dose. Her myocarditis, MIS-C, and infectious work up was negative except for positive EBV IgG. Laboratory studies revealed anemia, hypertriglyceridemia, hypofibrinogenemia, and hyperferritinemia. She initially responded to decadron;however, her symptoms recurred with steroid taper. Bone marrow biopsy revealed hemophagocytosis. Whole exome sequencing (WES) revealed a heterozygous variant of uncertain significance in UNC13D c.962C>A (p.Thr321Asn). She had multiple re-admissions with significantly elevated inflammatory markers, including extremely high IL2-R, IL-18 and CXCL9. Each episode was complicated by an acute viral infection. She responds to high dose steroids, anti-IL-1, and JAK inhibitors. Nonetheless, it has been difficult to wean decadron without triggering a flare. She continues to require increasing doses of baricitinib. Discussion(s): MAS may be seen as a complication of rheumatic diseases, as well as inborn errors of immunity. However, none of these conditions have been diagnosed in this patient despite extensive testing, including WES. The degree of her immune dysregulation has been very severe making her disease process unpredictable and extremely difficult to control. She has frequent flares precipitated by viral infections or attempts at adjusting her immunomodulators. Weaning her medications has been challenging as she continues to require increasing doses of baricitinib and corticosteroids. The UNC13D gene is associated with autosomal recessive familial hemophagocytic lymphohistiocytosis type 3 (FHL3). Our patient is heterozygous for an UNC13D variant of uncertain significance. Additional genetic inquiries with whole genome sequencing to help elucidate the underlying etiology of her severe condition is being conducted. We hypothesize she developed MAS due to a combination of genetic predisposition, prior EBV infection, and immune stress associated with the COVID-19 vaccine.

ABSTRACT
Background: Women are most at risk for Clostridium difficile infection in the early postpartum period. Clostridium difficile-associated colitis may be mistaken for the intestinal form of COVID-19 during the ongoing novel coronavirus infection pandemic. Case report: The paper describes a clinical case of a female patient diagnosed with the novel coronavirus infection and Clostridium difficile-associated pseudomembranous colitis in the early postpartum period. It depicts the diagnosis and treatment of the identified concurrent pathology. It demonstrates data from of an endoscopic examination of the colon and spiral computed tomography of the chest and provides laboratory confirmation of the infectious etiology of comorbidity. There are data available in the literature on the high rate and recurrent course of pseudomembranous colitis in the early postpartum period. It is noted that timely C. difficile eradication and pathogenetic treatment for the novel coronavirus infection allow relief of clinical symptoms. Conclusion(s): The case of the novel coronavirus infection concurrent with Clostridium difficile-associated pseudomembranous colitis in the early postpartum period is of interest in connection with the need for differential diagnosis of the etiology of diarrheal syndrome, the precise identification of which determines the further tactics of patient management and the nature of anti-epidemic measures.Copyright © A group of authors, 2021.
