Abstract
Amyloidosis is one of the rare systemic illnesses characterized by the deposition of amyloid fibrils in various organs and tissues. There is a common point between COVID-19 and systemic amyloidosis regarding the multiorgan involvement in the pathological process which leads to a heightened risk for severe morbidity and mortality in amyloidosis patients who contracted COVID-19. We performed a pathomorphological analysis of the autopsy records of 22 patients who had COVID-19 and pre-existing systemic amyloidosis. The premortem diagnosis of systemic amyloidosis was established in 55% of patients, and in other 45% of cases, amyloidosis was found at autopsy. Based on the results of immunohistochemical amyloid typing, amyloid A (AA) amyloidosis was detected in 23%, amyloid light chain (AL) lambda in 32%, AL kappa-in 9%, and transthyretin (ATTR) amyloidosis-in 36% of observations. Immunohistochemical staining with an antibody against SARS-CoV-2 Spike (S) protein revealed positive immune reactions in type II alveolocytes in 59% of deceased persons. The analysis of autopsy findings indicates that patients with systemic amyloidosis are more likely to experience an aggressive clinical course of COVID-19 which leads to a multiorgan failure and a higher risk of fatal outcome.

Abstract
Three years following the pandemic's emergence, COVID-19 has continued to affect much of the symptomatic population with widely varied respiratory complaints, fevers, numerous unexpected prodromal manifestations, and unknown long-term consequences. Scattered cases involving myopathies, rhabdomyolysis, and compartment syndrome have also been reported throughout the pandemic. Some similar cases have been attributed to systemic capillary leak syndrome (SCLS). Here, we report the development of compartment syndrome involving all extremities in a 57-year-old vaccinated female known to have COVID-19. In retrospect, we believe the clinical severity and the patient's sudden deterioration can also be attributed to the lesser-known SCLS. Treatment required fasciotomies of both forearms, arms, and legs. This is the most significantly involved case, leading to survival reported thus far. Lab abnormalities, misleading imaging, and symmetric involvement of all extremities posed a significant challenge to proper diagnosis and treatment. This case serves as a reminder for providers to remain cognizant of neurovascular emergencies during the workup of critically ill patients when the presentation is unrecognized and usual treatments are refractory. Its purpose is also to contribute to the global understanding of and response to COVID-19.

Abstract
Clinical knowledge about SARS-CoV-2 infection mechanisms and COVID-19 pathophysiology have enormously increased during the pandemic. Nevertheless, because of the great heterogeneity of disease manifestations, a precise patient stratification at admission is still difficult, thus rendering a rational allocation of limited medical resources as well as a tailored therapeutic approach challenging. To date, many hematologic biomarkers have been validated to support the early triage of SARS-CoV-2-positive patients and to monitor their disease progression. Among them, some indices have proven to be not only predictive parameters, but also direct or indirect pharmacological targets, thus allowing for a more tailored approach to single-patient symptoms, especially in those with severe progressive disease. While many blood test-derived parameters quickly entered routine clinical practice, other circulating biomarkers have been proposed by several researchers who have investigated their reliability in specific patient cohorts. Despite their usefulness in specific contexts as well as their potential interest as therapeutic targets, such experimental markers have not been implemented in routine clinical practice, mainly due to their higher costs and low availability in general hospital settings. This narrative review will present an overview of the most commonly adopted biomarkers in clinical practice and of the most promising ones emerging from specific population studies. Considering that each of the validated markers reflects a specific aspect of COVID-19 evolution, embedding new highly informative markers into routine clinical testing could help not only in early patient stratification, but also in guiding a timely and tailored method of therapeutic intervention.

Abstract
The established efficacy of electronic volatile organic compound (VOC) detection technologies as diagnostic tools for noninvasive early detection of COVID-19 and related coronaviruses has been demonstrated from multiple studies using a variety of experimental and commercial electronic devices capable of detecting precise mixtures of VOC emissions in human breath. The activities of numerous global research teams, developing novel electronic-nose (e-nose) devices and diagnostic methods, have generated empirical laboratory and clinical trial test results based on the detection of different types of host VOC-biomarker metabolites from specific chemical classes. COVID-19-specific volatile biomarkers are derived from disease-induced changes in host metabolic pathways by SARS-CoV-2 viral pathogenesis. The unique mechanisms proposed from recent researchers to explain how COVID-19 causes damage to multiple organ systems throughout the body are associated with unique symptom combinations, cytokine storms and physiological cascades that disrupt normal biochemical processes through gene dysregulation to generate disease-specific VOC metabolites targeted for e-nose detection. This paper reviewed recent methods and applications of e-nose and related VOC-detection devices for early, noninvasive diagnosis of SARS-CoV-2 infections. In addition, metabolomic (quantitative) COVID-19 disease-specific chemical biomarkers, consisting of host-derived VOCs identified from exhaled breath of patients, were summarized as possible sources of volatile metabolic biomarkers useful for confirming and supporting e-nose diagnoses.

Abstract
BACKGROUND Inflammatory responses contribute to tissue damage in COVID-19 and community-acquired pneumonia (CAP). Although predictive values of different inflammatory biomarkers have been reported in both, similarities and differences of inflammatory profiles between these conditions remain uncertain. Therefore, we aimed to determine the similarities and differences of the inflammatory profiles between COVID-19 and CAP, and their association with clinical outcomes. METHODS We report a prospective observational cohort study; conducted in a reference hospital in Latin America. Patients with confirmed COVID-19 pneumonia and CAP were included. Multiplex (Luminex) cytokine assays were used to measure the plasma concentration of 14 cytokines at hospital admission. After comparing similarities and differences in the inflammatory profile between COVID-19 and CAP patients, an unsupervised classification method (i.e., hierarchical clustering) was used to identify subpopulations within COVID-19 and CAP patients. RESULTS A total of 160 patients were included, 62.5% were diagnosed with COVID-19 (100/160), and 37.5% with CAP (60/160). Using the hierarchical clustering, COVID-19 and CAP patients were divided based on its inflammatory profile: pauci, moderate, and hyper-inflammatory immune response. COVID-19 hyper-inflammatory subpopulation had the highest mortality. COVID-19 hyper-inflammatory subpopulation, compared to pauci-inflammatory, had higher levels of IL-10 (median [IQR] 61.4 [42.0-109.4] vs 13.0 [5.0-24.9], P: < 0.001), IL-6 (48.1 [22.3-82.6] vs 9.1 [0.1-30.4], P: < 0.001), among others. Hyper-inflammatory vs pauci-inflammatory CAP patients were characterized by elevation of IFN2 (48.8 [29.7-110.5] vs 3.0 [1.7-10.3], P: < 0.001), TNFα (36.3 [24.8-53.4] vs 13.1 [11.3-16.9], P: < 0.001), among others. Hyper-inflammatory subpopulations in COVID-19 and CAP compared to the corresponding pauci-inflammatory subpopulations had higher MCP-1. CONCLUSIONS Our data highlights three distinct subpopulations in COVID-19 and CAP, with differences in inflammatory marker profiles and risks of adverse clinical outcomes. TRIAL REGISTRATION This is a prospective study, therefore no health care intervention were applied to participants and trial registration is not applicable.

Abstract
The clinical manifestation of coronavirus disease 2019 (COVID-19) mainly targets the lung as a primary affected organ, which is also a critical site of immune cell activation by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, recent reports also suggest the involvement of extrapulmonary tissues in COVID-19 pathology. The interplay of both innate and adaptive immune responses is key to COVID-19 management. As a result, a robust innate immune response provides the first line of defense, concomitantly, adaptive immunity neutralizes the infection and builds memory for long-term protection. However, dysregulated immunity, both innate and adaptive, can skew towards immunopathology both in acute and chronic cases. Here we have summarized some of the recent findings that provide critical insight into the immunopathology caused by SARS-CoV-2, in acute and post-acute cases. Finally, we further discuss some of the immunomodulatory drugs in preclinical and clinical trials for dampening the immunopathology caused by COVID-19.

Abstract
Opsoclonus myoclonus syndrome (OMS)/opsoclonus myoclonus ataxia syndrome (OMAS), also known as Kinsbourne's syndrome or 'dancing eyes-dancing feet' syndrome, is a rare central nervous system manifestation of COVID-19 but an increasing number of articles have reported patients in whom COVID-19 was complicated by OMS/OMAS. This narrative review aims at summarising and discussing current knowledge about the clinical presentation, diagnosis, treatment and outcome of SARS-CoV-2 associated OMS/OMAS. Altogether, 29 articles reporting 45 patients with SARS-CoV-2 associated OMS/OMAS were retrieved. Their ages ranged from 2 to 88 years. Three patients were children and the remainder adults. Gender was male in 32 patients and female in 13 patients. Opsoclonus was described in 29 patients, which was associated with myoclonus in 28 cases. Myoclonus was described in 43 patients, which was associated with opsoclonus and ataxia in 18 patients. Cerebral magnetic resonance imaging and cerebrospinal fluid investigations were not informative in the majority of the cases. OMS/OMAS was treated with steroids in 28 patients and with intravenous immunoglobulin (IVIG) in 15 patients. Clonazepam was given to 18 patients, levetiracetam to 13 patients, and sodium valproate to eight patients. Complete recovery was achieved in 12 cases and incomplete recovery in 22 cases. Diagnosing SARS-CoV-2 associated OMS/OMAS requires extensive neurological work up and exclusion of various differentials. SARS-CoV-2 associated OMS/OMAS may not always present with the full spectrum of manifestations but as an abortive syndrome. OMS/OMAS should not be missed as it usually responds favourably to steroids or IVIG.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) utilizes its Spike (S) glycoprotein to bind to the angiotensin-converting enzyme 2 (ACE2) receptor for cellular entry. ACE2 is a critical negative regulator of the renin-angiotensin system and plays a protective role in preventing tissue injury. Expression of ACE2 has been shown to decrease upon infection by SARS-CoV. However, whether SARS-CoV-2 down-regulates ACE2 and the underlying mechanism and biological impact of this down-regulation have not been well defined. Here we show that the SARS-CoV-2 infection down-regulates ACE2 in vivo in an animal model, and in cultured cells in vitro, by inducing clathrin- and AP2-dependent endocytosis, leading to its degradation in the lysosome. SARS-CoV-2 S-treated cells and ACE2 knockdown cells exhibit similar alterations in downstream gene expression, with a pattern indicative of activated cytokine signaling that is associated with respiratory distress and inflammatory diseases often observed in COVID-19 patients. Finally, we have identified a soluble ACE2 fragment with a stronger binding to SARS-CoV-2 S that can efficiently block ACE2 down-regulation and viral infection. Thus, our study suggests that ACE2 down-regulation represents an important mechanism underlying SARS-CoV-2-associated pathology, and blocking this process could be a promising therapeutic strategy.

Abstract
COVID-19 has been a source of several stays in intensive care units, increasing the number of prone positioning. In parallel, complications increased, such as facial ulcers. Herein, we present a literature review and a case series about facial pressure sores in COVID-19 patients during prone positioning. This study aimed to show that such facial pressure sores may require surgical intervention in specific cases.

Abstract
Background and objective The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that causes coronavirus disease 2019 (COVID-19) infection, with symptoms ranging from mild upper respiratory illness to multisystem organ failure, and even death. Since its discovery in December 2019, the SARS-CoV-2 virus has led to a global pandemic, rapidly spreading to countries around the world, with millions of reported deaths to date. As researchers around the world continue to analyze and interpret the data gathered regarding the novel virus, it is evident that its co-infection with various bacterial pathogens is associated with a worse overall prognosis. One such bacterial pathogen, Mycoplasma pneumoniae (M. pneumoniae), has been associated with an increase in inpatient mortality, length of hospital stay, and need for mechanical ventilation. The aim of this study was to evaluate the characteristics and outcomes of patients co-infected with SARS-CoV-2 and M. pneumoniae. We sought to determine if this co-infection led to increased incidence of ventilatory support, intensive care unit (ICU) stay, and mortality. Materials and Methods A multi-center retrospective study was conducted involving patients aged 18 years and older. We compared the incidence of in-hospital mortality, ICU stay, and mechanical ventilation support between COVID-19-positive patients with and without M. pneumoniae co-infection. Based on the collected data, a binary logistic regression model was implemented to assess the correlation between mortality and ventilatory support, while linear regression was used to study the length of stay (LOS) independent variable. Results A total of 1,208 patients with a positive SARS-CoV-2 test were identified. Among them, 604 (50%) had an M. pneumoniae co-infection. LOS (95% CI for the coefficient estimate [0.86, 1.05], p<0.001), need for mechanical ventilation (95% CI for the odds ratio [2.60, 6.02], p<0.001), and inpatient mortality (95% CI for the odds ratio [1.43, 2.97], p<0.001) among those co-infected were significantly higher compared to COVID-19 patients without concomitant M. pneumoniae infection. Conclusion COVID-19 with a concomitant M. pneumoniae infection was found to have worse outcomes and overall prognosis when compared to individuals with independent disease states. Based on retrospective data gathered from a large multicenter database, the rates of mortality, ventilatory support, and length of hospital stay were significantly worse in patients with a co-infection of SARS-CoV-2 and M. pneumoniae.

Abstract
Immune response to SARS-CoV-2 and ensuing inflammation pose a huge challenge to the host’s nicotinamide adenine dinucleotide (NAD+) metabolism. Humans depend on vitamin B3 for biosynthesis of NAD+, indispensable for many metabolic and NAD+-consuming signaling reactions. The balance between its utilization and resynthesis is vitally important. Many extra-pulmonary symptoms of COVID-19 strikingly resemble those of pellagra, vitamin B3 deficiency (e.g., diarrhoea, dermatitis, oral cavity and tongue manifestations, loss of smell and taste, mental confusion). In most developed countries, pellagra is successfully eradicated by vitamin B3 fortification programs. Thus, conceivably, it has not been suspected as a cause of COVID-19 symptoms. Here, the deregulation of the NAD+ metabolism in response to the SARS-CoV-2 infection is reviewed, with special emphasis on the differences in the NAD+ biosynthetic pathway’s efficiency in conditions predisposing for the development of serious COVID-19. SARS-CoV-2 infection-induced NAD+ depletion and the elevated levels of its metabolites contribute to the development of a systemic disease. Acute liberation of nicotinamide (NAM) in antiviral NAD+-consuming reactions potentiates “NAM drain”, cooperatively mediated by nicotinamide N-methyltransferase and aldehyde oxidase. “NAM drain” compromises the NAD+ salvage pathway’s fail-safe function. The robustness of the host’s NAD+ salvage pathway, prior to the SARS-CoV-2 infection, is an important determinant of COVID-19 severity and persistence of certain symptoms upon resolution of infection.

Abstract
Objectives There are indications that SARS-CoV-2 can trigger new onset or relapses of neuro-immunological disease. We report a patient with relapsing remitting multiple sclerosis (RRMS) under disease-modifying therapy (DMT) who experienced a relapse of RRMS after mild COVID-19. Case report The patient is a 27-year-old female with RRMS who developed a third exacerbation of RRMS under DMT two weeks after mild COVID-19. Compared to previous imaging findings, new studies revealed an increase in the lesion load and an enhancing lesion over two segments in the thoracic spine. The patient profited from steroids and replacement of her previous DMT. She tolerated the first SARS-CoV-2 vaccination without side effects 6 months after the SARS-CoV-2 infection. Conclusions SARS-CoV-2 infections can be followed by exacerbation of MS and failure of DMT. More arguments in favour than against a causal relation can be raised. Neurologist should remain vigilant for new or relapsing neuro-immunological disease following SARS-CoV-2 infections.

Abstract
Background We conducted this study to assess the diagnostic test properties of point of care ultrasonography (POCUS) of lung and cardiovascular system in prediction of mortality in COVID-19 patients. Methods This is a cross-sectional study of 178 Covid-19 patients; POCUS was performed within one hour of admission to the ICU. We estimated sensitivity, specificity, positive predictive value, negative predictive value for prediction of mortality. Results The mean (SD) age of these patients was 57.3 (12.8) years. The findings were on cardiac ultrasonography were: mild pericardial effusion (45%), chamber dilatation (15%), hypokinesia (11%), and low ejection fraction (8%). In our study, 30 patients (17%) had died. A cut-off score of > to 13 (for lung ultrasound score [LUS]) had high sensitivity for mortality (93.3%, 95% CI: 77.9–99.2%). However, low ejection fraction (92.3%, 95% CI: 86,6–96.1%), and thrombosis in either vein (96.5%, 95% CI: 92.0–98.9%) were specific for mortality. A combination of LUS > =13 or low ejection fraction or thrombosis or spontaneous echo contrast (slow flow) improved sensitivity for mortality to 96.7% (95% CI: 82.8–99.9%). The agreement between LUS of > =13 and CT score of moderate/severe was 85.7% (95% CI: 62.8–100%). The interrater agreement between these two parameters was 0.82 (95% CI: 0.68, 0.97). Conclusions Multi-organ POCUS is effective in diagnosis, prognosis, and management of COVID-19 patients. Rather than just lung ultrasound, clinicians should use multiorgan POCUS for early identification of severe lung involvement and thrombotic changes; it may help reduce mortality in these patients.

Abstract
The 2019 coronavirus disease (Coronavirus disease 2019, COVID-19) poses a great threat to the health of people in all countries of the world. Infection with SARS-CoV-2 (Severe acute respiratory syndrome-related coronavirus 2) is a respiratory disease characterized by the development of severe life-threatening complications. COVID-19 is more likely to be severe and sometimes fatal, especially in older people with co-morbidities. A topical issue is predicting the course of chronic diseases in people who have contracted a coronavirus infection. An increasing number of cases of arthritis associated with COVID-19 have been reported in the literature, making this condition worthy of further study. It is known that the development of osteoarthritis is associated with oxidative stress and excessive production of reactive oxygen species. Lipid peroxidation products can serve as a marker of the intensity of free radical processes. The aim of the study was to determine the concentration of lipid peroxidation products in the synovial fluid of patients with osteoarthritis after SARS-CoV2 infection. All study participants were divided into two groups. The first group (n=22) is patients with osteoarthritis of knee joints II-III degree. The second group (n=14) is patients with osteoarthritis of the knee joints II-III degree, who suffered a mild and moderate form of COVID-19 6-9 months ago. In the conducted studies, the products of lipid peroxidation in the synovial fluid of patients of all research groups were evaluated.The content of diene conjugates was determined in the heptane-isopropanol extract by the spectrophotometric method, Schiff bases by the fluorimetric method. The content of TBA-active products was determined by the reaction with thiobarbituric acid (TBA). The processing of the research results was carried out using generally accepted methods of variational statistics. It was established that in the synovial fluid of patients with osteoarthritis of the knee joints who contracted COVID-19, the concentration of lipid peroxidation products increases compared to the group of patients with osteoarthritis (diene conjugates – by 1.7 times, TBА-active compounds – by 1,5 times, Schiff bases – 1.3 times). The detected changes indicate a violation of the oxidative-antioxidant balance. This indicates the prevalence of free radical processes and the development of oxidative stress directly in the joint. The results obtained by us indicate that patients with osteoarthritis may develop more severe joint damage and complications after infection with COVID-19.
