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
Objectives: Treatment of severe respiratory distress syndrome (ARDS) due to COVID-19 by veno-venous extracorporeal membrane oxygenation (VV-ECMO) had a mortality of up to 70% in Germany. Many patients with COVID-19 need VV-ECMO support longer than 28 days (long-term VV-ECMO). Evidence on mortality, complications during intensive care, functional status after discharge and mortality-predictors for patients supported with long-term VV-ECMO is lacking. Method(s): Retrospective study of 137 consecutive patients treated with VV-ECMO for ARDS due to COVID-19 at University Hospital Regensburg from March 2020 to March 2022. Result(s): 38% (n=52;87% male) of patients needed longterm VV-ECMO support. In these, SOFA score (median [IQR]) at ECMO initiation was 9 [8-11], age 58.2 [50.6- 62.5] years, PaO2/FiO2-ratio 67 [52-88] mmHg, pCO262 [52-74] mmHg, Murray-Score 3.3 [3.0-3.6] and PEEP 15 [13 - 16] cmH2O. Duration of long-term support was 45 [35-65] days. 26 (50%) patients were discharged from the ICU. Only one patient died after hospital discharge. At VVECMO initiation, baseline characteristics did not differ between deceased and survivors. Complications were frequent (acute kidney injury: 31/52, renal replacement therapy: 14/52, pulmonary embolism: 21/52, intracranial hemorrhage 8/52, major bleeding 34/52 and secondary sclerosing cholangitis: 5/52) and more frequent in the deceased. Karnofsky index (normal 100) after rehabilitation was 70 [57.5-82.5]. Twelve of the 18 patients discharged from rehabilitation had a satisfactory quality of life according to their own subjective assessment. Four patients required nursing support. Mortality-predictors within the first 30 days on VV-ECMO only observed in those who deceased later, were: Bilirubin >5mg/dl for > 7 days, pulmonary compliance <10ml/mbar for >14 days, and repeated serum concentrations of interleukin 8 >150ng/L. Conclusion(s): Long-term extracorporeal lung support in patients with COVID-19 resulted in 50 % survival and subsequently lead to a satisfactory quality of life and functionality in the majority of patients. It should preferably be performed in experienced centers because of a high incidence of complications. Several findings during the early course were associated with late mortality but need validation in large prospective studies.
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: It is important to predict the prognosis during hospital admission of Covid-19 patients. The purpose of this study was to see how CRP/ Albumin (CAR) and Platelet/Lymphocyte (PLR) ratios, obtained from patients in the intensive care unit (ICU) within the first 24 hours of their hospitalization with a Covid-19 diagnosis, predictmortality and how they correlated with acute physiology and chronic health evaluation (APACHE II) and sequential organ failure assessment (SOFA). Method(s): Using hospital records, records of 83 patients hospitalized in the ICU with a diagnosis of Covid-19 between 11.03.2020 and 01.01.2021 were retrospectively analyzed . Patients were divided into two groups discharged (Group I) and exits (ex) group (Group II). CAR and PLR were recorded during the first 24 hours of ICU admission, and APACHE II and SOFA scores were computed. The calculated CAR and PLR were correlated with APACHE II and SOFA scores and their association with mortality was investigated. Result(s): SOFA, APACHE II, PLO, and age were higher, and albumin was lower in patients in the mortal course (p<0.05). ROC analysis revealed that APACHE II and SOFA scores could be employed to estimate mortality. Conclusion(s): We believe that APACHE II and SOFA scores can be used to predict mortality in patients admitted to the ICU due to Covid-19, whereas CRP/Albumin and Platelet/Lymphocyte ratios cannot.

ABSTRACT
COVID-19 is caused by the novel coronavirus SARS-CoV-2. First started in Wuhan, COVID-19 has spread everywhere, including Indonesia. COVID-19 can cause severe pneumonia, severe acute respiratory distress syndrome (ARDS) symptoms, and multiple organ failure. According to the WHO, COVID-19 generally has an incubation period of 5-6 days, ranging from 1 to 14 days. However, in Jakarta, the cases have decreased significantly since the implementation of PPKM (Restrictions of Activity), running since early July 2021. The government claimed that the PPKM rule has significantly impacted COVID-19 cases, decreasing every day, especially in Jawa-Bali Region. In addition, the Vaccination rate in Indonesia also played a significant part in decreasing COVID-19 cases, with Jakarta currently standing with 9 million people fully vaccinated per December 2021. To monitor the development of COVID-19 in Jakarta and provide information to the public about health facilities, especially hospitals in Jakarta, in this study, the distribution area of COVID-19 cases will be mapped with CHIME using ArcGIS Online tools. The analysis results obtained based on the mapping results that most cases were in the Cengkareng area, and the area with the most hospitals werein East Jakarta. © 2022 IEEE.
ABSTRACT
The novel coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).Mortality attributable to COVID-19 remains considerably high, with case fatality rates as high as 8-11%. Early medical intervention in patients who are seriously and critically ill with COVID-19 reduces fatal outcomes. Thus, there is an urgent need to identify biomarkers that could help clinicians determine which patients with SARS-CoV-2 infection are at a higher risk of developing the most adverse outcomes, which include intensive care unit (ICU) admission, invasive ventilation, and death. In COVID-19 patients experiencing the most severe form of the disease, tests of liver function are frequently abnormal and liver enzymes are found to be elevated. For this reason, we examine the most promising liver biomarkers for COVID-19 prognosis in an effort to help clinicians predict the risk of ARDS, ICU admission, and death at hospital admission. In patients meeting hospitalization criteria for COVID-19, serum albumin < 36 g/L is an independent risk factor for ICU admission, with an AUC of 0.989, whereas lactate dehydrogenase (LDH) values > 365 U/L accurately predict death with an AUC of 0.943.The clinical scores COVID-GRAM and SOFA that include measures of liver function such as albumin, LDH, and total bilirubin are also good predictors of pneumonia development, ICU admission, and death, with AUC values ranging from 0.88 to 0.978.Thus, serum albumin and LDH, together with clinical risk scores such as COVID-GRAM and SOFA, are the most accurate biomarkers in the prognosis of COVID-19.Copyright © 2021 Sociedad Medica del Hospital General de Mexico.

ABSTRACT
Since the outbreak in December 2019, the SARS-CoV-2 pandemic virus has been a major public health problem in all countries of the world. The virus is transmitted by inhalation of respiratory droplets from the patient or asymptomatic carrier and is highly contagious. The clinical disease in children is similar to any acute respiratory infection with predominant upper respiratory symptoms, but occasionally can progress to pneumonia with acute respiratory distress syndrome and multiorgan failure. The disease is milder in children than in adults, with low mortality, and it appears that infants and young children have a somewhat more severe clinical course. Diagnosis is made by detecting the virus from respiratory samples (mainly nasopharyngeal and oropharyngeal swabs) using polymerase chain reaction. Treatment is usually symptomatic, and in severe and critical forms, the use of one of the antiviral drugs (lopinavir-ritonavir, remdesivir, hydroxychloroquine) may be consideredCopyright © 2020 Croatian Paediatric Society.

ABSTRACT
Background: COVID-19 syndrome is associated with high morbidity and mortality in haemodialyzed patients. Pancreatic Stone Protein (PSP) is an early biomarker of sepsis and a prognostic biomarker of disease severity in critically-ill patients and can be rapidly measured at the patient's bedside with a point-of-care-test from a small drop of whole blood. The aim of our pilot was to investigate PSP in patients requiring haemodialysis with SARS-CoV-2 infection, at different severities of COVID-19 disease. Method(s): Between February and July 2021, 23 patients (6 severe COVID-19 with Acute Kidney Injury, 6 moderate COVID-19 haemodialyzed, 2 haemodialyzed without COVID-19 and 3 healthy controls) were recruited at the University Hospital of Foggia for PSP evaluation. Biomarker's measurements were performed within 48 hours after admission or upon arrival for haemodialysis (pre-treatment). PSP was measured at the patient's bedside with "abioSCOPE", a point-of-care test capable of evaluating PSP levels in five minutes from a small drop (50mul) of whole blood or serum. Result(s): The preliminary results of this pilot study showed a trend for PSP to increase along with the severity of disease. In fact, serum PSP levels were significantly higher in Intensive Care Unit subjects than in COVID-19 negative haemodialysis subjects and controls (ANOVA p=0.032). Furthermore, PSP levels were significantly higher in subjects who died (p<0.017). Whether this increase is due to the kidney injury or COVID-19 disease remains unknown, and more research is needed to understand the relationship. Conclusion(s): Several clinical studies published in literature have shown the predictive value of PSP in the early identification of sepsis and severity of the clinical outcome. In our experience we have seen a trend for PSP to increase with disease severity also in COVID-19 patients. These results are preliminary, but PSP was significantly higher in patients who died, in accordance with the literature. This experience also has demonstrated the feasibility of a point of care system to be easily implemented in the unit and adopted by personnel and its design enables fast results and immediate decisions to be taken, especially in urgent situations.
ABSTRACT
Introduction: Mucormycosis is a rare, severe fungal infection with an incidence of 0.005 to 0.17 per million.1 but incidence has risen recently, particularly in the Asian subcontinent, due to use of immunosuppression for Covid19.2 Presentations can vary and are classified into: rhino-orbito-cerebral, pulmonary, cutaneous, disseminated, renal and gastrointestinal. Risk factors include diabetes, immunosuppression, iron overload, malnutrition, and prematurity.1,3 Although mucormycosis has an extremely high mortality rate and disseminated infection is usually fatal, treatment options exist if diagnosed early and surgical debridement may be curative. Objective(s): We present a case of mucormycois in a female patient in her 40s who was immunosuppressed with methotrexate for rheumatoid disease. This case is discussed to increase awareness of critical illness caused by opportunistic invasive fungal infections in immunosuppressed patients and promote timely identification and management. Method(s): We detail the clinical context and management of a patient with mucormycosis and discuss relevant literature. Result(s): A female patient in her 40s who had been experiencing upper respiratory tract symptoms for several weeks, including cough and brown sputum, was admitted with a presumptive diagnosis of methotrexate toxicity after a full blood count performed by the general practitioner demonstrated pancytopenia. Initially, National Early Warning System 2 score (NEWS2) was 2 but became intensely hypertensive during blood transfusion and then profoundly shocked with an escalating NEWS2. Broad-spectrum antibiotics and fluconazole were commenced for neutropenic sepsis and the patient was referred to critical care in multiple organ failure. Computerised tomography (CT) scan of the chest, abdomen and pelvis showed "left upper lobe consolidation, which with neutropenia might represent an angioinvasive aspergillosis". She had multiple areas of skin discolouration and desquamation. Haematology and Infectious Diseases opinions were sought, and a bone marrow biopsy was performed which showed severe toxic effects consistent with sepsis/life threatening infection. Progressive proptosis was noted, and CT scan of her head was requested. Sadly, she was never stable enough for CT transfer. Beta D Glucan and aspergillus antigen serology was negative. Broncho-alveolar lavage demonstrated Candida albicans and then, later, Rhizopus arrhizus was isolated and anti-fungal treatment changed to voriconazole and then amphotericin B. Upon reviewing the notes in light of the positive culture for Rhizopus, the patient had likely been exhibiting symptomatic Mucormycosis sinus infection for some time prior to this admission with disseminated infection. The patient's condition continued to deteriorate and she sadly died. Conclusion(s): * The Early Warning Score significantly underestimated how unwell the patient was upon arrival in ED, a systems-based assessment would have demonstrated that the patient had multiple system dysfunction and significant potential to deteriorate suddenly despite having stable observations * The methotrexate level has no clinical value in diagnosing or refuting a diagnosis of methotrexate toxicity * A full examination of the immunosuppressed patient including ENT is a necessity when searching for a source of infection * Invasive fungal infections can cause multi-system symptoms and atypical presentations * As a greater proportion of patients have received systemic immunosuppression for Covid-19, vigilance for more unusual pathogens, including Mucormycosis by clinicians is advised.
ABSTRACT
The current outbreak of COVID-19 is caused by the SARS-CoV-2 virus that has affected > 210 countries. Various steps are taken by different countries to tackle the current war-like health situation. In India, the Ministry of AYUSH released a self-care advisory for immunomodulation measures during the COVID-19 and this review article discusses the detailed scientific rationale associated with this advisory. Authors have spotted and presented in-depth insight of advisory in terms of immunomodulatory, antiviral, antibacterial, co-morbidity associated actions, and their probable mechanism of action. Immunomodulatory actions of advised herbs with no significant adverse drug reaction/toxicity strongly support the extension of advisory for COVID-19 prevention, prophylaxis, mitigations, and rehabilitation capacities. This advisory also emphasized Dhyana (meditation) and Yogasanas as a holistic approach in enhancing immunity, mental health, and quality of life. The present review may open-up new meadows for research and can provide better conceptual leads for future researches in immunomodulation, antiviral-development, psychoneuroimmunology, especially for COVID-19.Copyright © 2021, Institute of Korean Medicine, Kyung Hee University.
ABSTRACT
Considering the commonality of the pathogenetic links of the critical forms of COVID-19 and influenza AH1N1pdm09 (cytokine over-release syndrome), the question arises: will the predictors of an unfavorable outcome in patients on mechanical ventilation and, accordingly, the universal tactics of respiratory support in these diseases be identical? Objective. In a comparative aspect, to characterize patients with influenza AH1N1pdm09 and COVID-19 who were on mechanical ventilation, to identify additional clinical and laboratory risk factors for death, to determine the degree of influence of respiratory support (RP) tactics on an unfavorable outcome in the studied category of patients. Patients and methods. Patients treated on the basis of resuscitation and intensive care departments of the State Budgetary Healthcare Institution "SKIB" in Krasnodar and the State Budgetary Healthcare Institution "IB No 2" in Sochi were studied: group 1 - 31 people with influenza AH1N1pdm09 (21 people died - subgroup 1A;10 people survived - subgroup 1B) and group 2 - 50 people with COVID-19 (29 patients died - subgroup 2A;21 people survived - subgroup 2B). All patients developed hypoxemic ARF. All patients received step-by-step tactics of respiratory support, starting with oxygen therapy and ending with the use of "traditional" mechanical ventilation. Continuous variables were compared in subgroups of deceased and surviving patients for both nosologies at the stages: hospital admission;registration of hypoxemia and the use of various methods of respiratory therapy;development of multiple organ dysfunctions. With regard to the criteria for which a statistically significant difference was found (p < 0.05), we calculated a simple correlation, the relative risk of an event (RR [CI 25-75%]), the cut-off point, which corresponded to the best combination of sensitivity and specificity. Results. Risk factors for death of patients with influenza AH1N1pdm09 on mechanical ventilation: admission to the hospital later than the 8th day of illness;the fact of transfer from another hospital;leukocytosis >=10.0 x 109/l, granulocytosis >=5.5 x 109/l and LDH level >=700.0 U/l at admission;transfer of patients to mechanical ventilation on the 9th day of illness and later;SOFA score >=8;the need for pressor amines and replacement of kidney function. Predictors of poor outcome in ventilated COVID-19 patients: platelet count <=210 x 109/L on admission;the duration of oxygen therapy for more than 4.5 days;the use of HPNO and NIV as the 2nd step of RP for more than 2 days;transfer of patients to mechanical ventilation on the 14th day of illness and later;oxygenation index <=80;the need for pressors;SOFA score >=8. Conclusion. When comparing the identified predictors of death for patients with influenza and COVID-19 who needed mechanical ventilation, there are both some commonality and differences due to the peculiarities of the course of the disease. A step-by-step approach to the application of respiratory support methods is effective both in the case of patients with influenza AH1N1pdm09 and patients with COVID-19, provided that the respiratory support method used is consistent with the current state of the patient and his respiratory system, timely identification of markers of ineffectiveness of the respiratory support stage being carried out and determining the optimal moment escalation of respiratory therapy.Copyright © 2022, Dynasty Publishing House.

ABSTRACT
Introduction: Acute kidney injury (AKI) is a complication of SARS-CoV-2 disease, associated with worse clinical outcomes. Renal replacement therapy (RRT) in combination with sequential extracorporeal blood purification therapies (EBPT) might support renal function, attenuate systemic inflammation, and prevent or mitigate multiple organ dysfunctions. Method(s): We retrospectively analyzed 20 patients admitted in ICU for ARDS and who developed moderate-to-severe AKI requiring RRT. Cytokine hemadsorption with Cytosorb was performed in association with CRRT. The main indication for this treatment was the worsening of hemodynamic and respiratory conditions and suspicion of cytokine storm. The protocol consisted in the use of 3-4 cartridges in total;among these, the first 2 were changed after 12 hours of treatment to maximize cytokine removal, while the others after 24 hours. We examined comorbidities, clinical and laboratory characteristics and the impact of treatment in terms of mortality rate and changes in data before and after treatment. Result(s): Nineteen patients (95%) had an AKI at any time during their ICU stay. Of these, 5 patients (25%) had AKI stage II and 14 patients (70%) had AKI stage III. All patients included in this subgroup were mechanical ventilated and required vasopressor's use. Mean prescribed CRRT dose was 31.2 +/- 11.7 ml/kg/h. The median time to strating RRT after ICU admission was 7 days (IQR 3.5-15 days) and the median duration was 7 days (IQR 2.5-12.5 days). Mean SOFA score at the time of RRT start was extremely high (14.5 +/- 2.8). Mortality rate was important (18 patients, 90%) in our cohort. Comparing clinical and laboratory data before and after treatment, a significant improvement of inflammatory markers was reported, with the reduction of C-reactive protein (CRP, 143 [62.1- 328.5] vs 83.5 [66.7-153.5] mg/L);however, no significant changes in IL-6, WBC and PCT values were observed. A slight increase of PaO2/FiO2 were described, although not statistically significant (PaO2/FiO2 ratio 144 [82.7-174.2] vs 183 [132-355.5] mmHg). Conclusion(s): Our experience supports the need of an adequate timing for the use of Cytosorb in critically ill patients with Covid-19. Although a discrete efficacy in improving inflammatory cascade, the late use of EBPT, when organ dysfunction was already ongoing, didn't impact survival.
ABSTRACT
Introduction: Active cancer increases the odds of death among patients with COVID-19.1 Cancer patients may be at increased risk of complications and mortality from COVID-19 owing to the systemic effects of malignancy, immune suppression after chemotherapy, treatment-related complications and presence of co-morbidities.2 They may develop serious complications necessitating ICU admission. In a meta-analysis, the pooled mortality in cancer patients with COVID-19 admitted to an ICU was 60.2%.3 Our hospital is a tertiary referral cancer centre, and the ICU admitted cancer patients with Covid-19 throughout the pandemic. Objective(s): To determine the 30-day in-hospital mortality of adult cancer patients with Covid-19 admitted to the ICU. We also aimed to determine the factors associated with mortality in cancer patients with Covid-19. Method(s): After approval from the Institutional Ethics Committee, data of all cancer patients (age = 16 years) with Covid-19 admitted to the ICU between March 2020 and March 2021 were retrieved from the hospital records. In case of multiple ICU admissions, data from the first admission was recorded. Data recorded included demographic details, type of cancer (solid, haematological), surgical status, APACHE-II and SOFA scores, C-reactive protein, and interventions in ICU. The primary outcome was 30-day in-hospital mortality. Data were analysed using Man-Whitney test and chi-square test. A multivariable regression analysis was carried out to determine factors associated with mortality. Result(s): Data of 127 cancer patients with Covid-19 was analysed. The median [interquartile range, IQR] age was 55 (43-62) years, and there were 50 females (39.3%). Comorbidities were present in 46 (36%) patients, the commonest being diabetes (29 patients) and hypertension (31 patients). The median [IQR] APACHE-II and SOFA scores were 15[8-20] and 4[2-7], respectively. Overall, 62/127 patients died, and 30-day hospital mortality was 49%. There were 30 patients with haematological malignancy and 97 with solid tumours with 30-day in-hospital mortality rates of 46.7% and 49.5%, respectively;p = 0.84). Amongst patients with solid tumours, there was no difference in mortality in surgical patients compared to non-surgical patients (43.3% vs. 52.2%;p = 0.42). Table 1 summarises the parameters and interventions in survivors and non-survivors. On multivariable analysis, only the change in SOFA score from Day 1 to Day 3 was independently associated with outcome (Odds ratio 1.36 (95% confidence interval 1.01-1.84, p-0.04). Conclusion(s): In patients with cancer and Covid-19 and age =16 years admitted to our ICU, the crude 30-day hospital mortality was 47%. There was no association of mortality with cancer type or surgical status. The only independent predictor of mortality was progression of organ failure. Cancer patients with Covid-19 have a reasonable outcome and should be given a trial of intensive care.
ABSTRACT
Background: Septic shock is a life-threatening organ dysfunction caused by a dysregulated host response to infection. The reduction of pro-inflammatory and anti-inflammatory mediators by hemoadsorption represents a new tool in the treatment of sepsis. In the present case series, we evaluated the impact of CytoSorb on adult patients with septic shock. Method(s): Patients with septic shock, admitted to Intensive Care Unit (ICU) from March 1, 2021 to February 28, 2022 who received CytoSorb therapy within 72 hours of admission were enrolled in the study. The severity of clinical conditions at admission was assessed by the SAPS II and SOFA scores;The magnitude of the inflammatory response was estimated using the plasmatic levels of C reactive protein (CRP) and interleukin-6 (IL-6). The effect of CytoSorb therapy on the inflammatory state, was evaluated measuring the percentage reduction of IL-6 and CRP. Time elapsed from ICU admission and the start of CytoSorb therapy was also assessed. T-test was used to compare the means of the groups of Survivors and No survivors. Fisher's test was used to evaluated the difference in mortality between Covid and No covid patients. Result(s): Twelve patients were evaluated. Six patients tested positive for covid-19, while the other six did not. Table 1 shows the values of age, SAPSII, SOFA, IL-6, CRP, PCT and timing between the survivors and the no survivors. Overall, there was no significant difference between the two groups in terms of SAPSII, SOFA, age, CRP. There was a significant difference in the timing of Cytosorb start and percentage of IL-6 removal: In surviving patients the timing of intervention was shorter (3,3+/-1,8 vs 23,5+/-18,9 hours) than in non- survivors. The IL-6 removal rate was significantly higher in the survivor group (70,8+/-15,87 vs 33,2+/-12,26). Conclusion(s): In survivors the timing of CytoSorb therapy was shorter and the IL-6 removal rate was higher than in non-survivors. This suggest that the early applying of CytoSorb adsorber in combination with Continuous Renal Replacement Therapy (CRRT) techniques, could increase the survival rate of septic shock patients. Using CytoSorb was safe and well tolerated with no device-related adverse events during or after the treatment.
ABSTRACT
Objectives: To present a series of immunosuppressed patients (oncohematological disease, congenital immunosuppression, hematopoietic stem cell (HSCT), and solid organ transplant) assisted on ECMO. Method(s): Descriptive, retrospective study (2011-2020) of a cohort of 9 immunosuppressed patients, supported on ECMO. Medical records were reviewed and demographic, clinical, and analytical variables were collected. Result(s): In our series of 9 patients, 5 were male, the median age was 8 years [RIC 3-11 years]. Considering the underlying disease, 6 were oncologic, 1 liver transplant and 2 with congenital immunodeficiency after HSCT. 4 were under active chemotherapy (median 6 days after the last cycle [RIC 5-188]). 6 were admitted due to acute respiratory failure, 3 due to hemodynamic instability (3/9), (one septic shock). The median PEEP was 12 [RIC 9-15] and FiO2 100% (81-100%). 78% (6) required vasoactive drugs (median inotropic score 35 [RIC 0-75]. 40%. 5 had severe neutropenia and/or plateletopenia in the 24 hours prior to ECMO, and alterations in acid-base balance (median pH 7. 1 [RIC 6.9-7.15]. 5 were on multiorgan failure. TPrimary ECMO transport was performed in 4 patients (44%). Cannulation was peripheral in 80% (57% cervical, 43% femoral) and central in 20%;70% VA-ECMO. Median time of assistance was 15 days [RIC 3.5-31.5] in cardiac ECMO (4), and 29 days [RIC 13.5-42] and in pulmonary ECMO (n=5). The median total time of admission was 45 days [RIC 27-59]. 9 had an infection, 2 COVID after HSCT, and 8 bleeding complications, but only one required surgical revision. Renal replacement therapy was used in 5 (median 9 days [RIC 5-34.5]). Other therapies used were polymyxin hemadsorption(2), intratracheal surfactant(2), plasma exchange(1), infusion of mesenchymal cells(1) and specific memory T lymphocytes(2). 4 patients died, 5 survived decannulation, 2 died later, with an overall survival rate to hospital discharge of 33% (3/9). Conclusion(s): Despite having a worse prognosis, ECMO can increase survival in immunosuppressed patients, in situations that are challenging and require a multidisciplinary approach.
ABSTRACT
Up to 70% of patients hospitalized for COVID-19 need respiratory support, up to 10% need high-flow oxygen therapy, non-invasive and invasive ventilation. However, standard methods of respiratory support are ineffective in 0.4-0.5% of patients. In case of potentially reversible critical refractory respiratory failure that patients may require ECMO. Management of patients with extremely severe COVID-19 associates with numerous clinical challenges, including critical illness, multiple organ dysfunction, blood coagulation disorders, requiring prolonged ICU stay and care, use of multiple pharmacotherapies including immunosuppressive drugs. Pharmacological suppression of immunity is associated with a significant increase in the risk of secondary bacterial and fungal infections. Currently, data on epidemiology of secondary infections in patients with COVID-19 undergoing ECMO is limited. Aim. To study the prevalence and etiology of secondary infections associated with positive blood cultures in patients with extremely severe COVID-19 requiring ECMO. Materials and methods. A single-center retrospective non-interventional epidemiological study including 125 patients with extremely severe COVID-19 treated with ECMO in April 2020 to December 2021. Results. Out of 700 blood culture tests performed in 125 patients during the study, 250 tests were positive confirming bacteremia/fungemia. Isolated pathogens varied depending on the duration of ECMO: gram-positive bacteria (primarily coagulase-negative staphylococci) dominated from the initiation of ECMO support;increased duration of ECMO associated with an increasing the proportion of pathogens common in ICU (Klebsiella pneumoniae and/or Acinetobacter baumannii with extensively drug resistant and pan-drug resistant phenotypes, and vancomycin-resistant Enterococcus faecium). When ECMO lasted more than 7-14 days, opportunistic pathogens (Candida species, Stenotrophomonas maltophilia, Providencia stuartii, non-diphtheria corynebacteria, Burkholderia species and others) prevailed as etiological agents. Conclusion. Longer duration of ECMO resulted in increasing the rates of infectious complications. In patients undergoing ECMO for more than 14 days, the microbiological landscape becomes extremely diverse, which hampers choosing an empirical antimicrobial therapy. Since potential pathogens causing secondary infections in patients during ECMO are difficult to predict, rapid identification of rare opportunistic pathogens and their sensitivity profile, followed by targeted administration of antimicrobials, seems most beneficial.Copyright © 2023, V.A.

ABSTRACT
Background: NFX1-type zinc finger-containing 1 (ZNFX1) is an interferon-stimulated double-stranded RNA sensor that restricts the replication of RNA viruses in mice. ZNFX1 deficiency in humans is very rare;to date, only fifteen cases have been reported by Vavassori S et al. (10.1016/j.jaci.2021.03.045). The disease presented in all cases as severe viral infections complicated by multisystem inflammation evolved to multiorgan failure with a high mortality rate. Pediatric Allergy and Immunology Section at Queen Rania Children's Hospital in Jordan had confirmed the diagnosis of ZNFX1 deficiency in an infant at his first presentation with severe viral illness based on the positive family history of one sibling death caused by complicated COVID-19 infection. Case presentation: A 12-month-old boy was born to consanguineous parents, full-term, with no NICU admission. He was doing well till the age of four months when he was admitted to the hospital with fever, hypoactivity, and maculopapular skin rash. On admission, he was ill, hypoactive, and febrile, and a physical exam showed hepatosplenomegaly and maculopapular skin rash. His lab showed thrombocytopenia, elevated transaminases, hyperferritinemia, and high CRP;he was treated with broad-spectrum antibiotics, but he continued to deteriorate, and his infectious workup was unrevealing, including COVID-19 PCR. His older sibling died at eight months in 2020 when she got a COVID-19 infection, deceased after rapid deterioration evolved to multiorgan failure. Unfortunately, she had no stored DNA, as she was treated at a peripheral hospital. Based on this presentation and the fatal COVID-19 infection, pediatric immunology service got consulted;we did an immunological workup, which showed normal lymphocyte subsets, Immunoglobulins, and bacterial antibodies. Whole exome sequencing showed a homozygous frameshift mutation in the ZNFX1 gene, protein change defect had detected;p.Tyr555MetfsTer6, and nucleotide change variant: c.1663_1665delTACinsAT. Family screening showed heterozygous for the same variant in both parents and a healthy sibling. The patient was diagnosed with the hemophagocytic lymphohistiocytosis-like disease and treated with steroids, intravenous immunoglobulin, and antimicrobials, he showed complete recovery, and we are going to do bone marrow transplantation as his brother is 8/8 HLA matched.Copyright © 2023 Elsevier Inc.
ABSTRACT
Introduction: TBX1 haploinsufficiency is an inborn error of immunity with the phenotype of DiGeorge Syndrome. DiGeorge Syndrome has variable immunodeficiency associated with grade of thymic hypoplasia ranging from mild with no infections to severe requiring thymus implant. Enterovirus is an example of an opportunistic infection that can be fatal in these patients. Case Presentation: A 1 year old girl with TBX1 haploinsufficiency complicated by Tetralogy of Fallot, pulmonary atresia, high arched palate, and vesicovaginal fistula presented for elective cardiac repair surgery from another country due to failure to thrive and cyanosis. She had no prior infectious history but was on sulfamethoxazole-trimethoprim for prophylaxis. She was asymptomatic with a negative COVID test but no other infectious studies performed. Immediately postoperatively, she was febrile and nasal respiratory viral panel was positive for rhinovirus/enterovirus with increased procalcitonin and leukocytosis with left shift. She decompensated with multi-organ failure and cardiac arrest on postoperative day two. She was cannulated to veno-arterial extracorporeal membrane oxygenation (ECMO). Pre-operatively, she had a normal absolute lymphocyte count. No thymus tissue was observed in surgery. She had profound CD3 lymphopenia to 130 cells/cmm when critically ill. Enteroviral meningitis was suspected as no infectious, cardiac, or other pathology could be identified causing decompensation. Enteroviral serum polymerase chain reaction (PCR) test was negative while lumbar puncture deferred due to clinical status. She was treated with immunoglobulin. Offlabel investigational drug pocapavir was considered but deferred to patient's irreversible neurological status. The patient was disconnected from ECMO and expired. Discussion(s): Though we cannot confirm that this patient had enteroviral meningitis, invasive enteroviral infections are associated with elevated transaminases, coagulopathy, and seizures all present in our patient. There has also been reported negative serum enteroviral PCR but positive CSF enteroviral PCR in an immunodeficient patient. Additionally, this case highlights the importance of immunologic evaluation in patients with DiGeorge Syndrome and questions if asymptomatic viral screening for viruses like enterovirus should be considered pre-operatively in patients with inborn errors of immunity. This case highlights potential treatment options for invasive enteroviral infections in patients with inborn errors of immunity: high dose immunoglobulin, fluoxetine, and pocapavir.Copyright © 2023 Elsevier Inc.
ABSTRACT
COVID-19 is a multisystem disease that requires holistic management. Most patients will experience mild symptoms including cough, fever and mild dyspnoea. A small proportion of patients will have severe manifestations including respiratory failure, ARDS and multiorgan failure. Extrapulmonary features are common and include gastrointestinal, thromboembolic, neurological, cardiac, renal, endocrine and dermatological manifestations. The care of COVID-19 patients requires close attention to these features. This includes respiratory support (such as supplemental oxygen, NIV and awake proning);fluid, electrolyte and nutrition management;prevention, detection and treatment of thrombotic events;management of diabetic complications;review of medications;appropriate use of antibiotics;and evidence-based use of therapeutic agents such as corticosteroids, antivirals such as remdesivir and other emerging therapies such as immunomodulating agents. Early planning for treatment escalation and decision making around the appropriateness of cardiopulmonary resuscitation are crucial as deterioration can be rapid. Prolonged symptoms occur in a minority of patients and longitudinal follow-up is required.Copyright © ERS 2021.
