Liver injury associated with high value of D-dimer plasmatic level in COVID-19 patients.

BACKGROUND: The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), causal agent of the coronavirus disease (COVID-19), has infected millions of people worldwide. Currently, the scientific community debates on the direct viral responsibility of liver damage or whether the observed changes are secondary manifestations of systemic inflammation triggered by COVID-19. The hepatic involvement is associated with worse clinical outcomes and higher risk of COVID-19 related morbidity and mortality. Furthermore, SARS-CoV-2 infection may predispose patients to thrombotic disease due to excessive inflammation, platelet activation, and endothelial dysfunction. METHODS: In this paper, we reported a cross-sectional analysis of five patients affected by a severe form of COVID-19, who died between April 11 and May 1, 2020. Each patient has been subjected to a medico-legal autopsy in which both gross and histological liver changes were evaluated, as well as the correlation with the related coagulation profile. RESULTS: In three cases of our cohort, the thromboembolism was recognized as cause of death. Furthermore, a significant statistical difference between D-dimer values at hospital admission and death among enrolled patients (p= 0.033), was evaluated. No patient has recorded a pre-existing liver disease. CONCLUSIONS: Our results support the evidence that hepatic damage in subjects with severe form of COVID-19 is related to the changes in coagulative and fibrinolytic pathways. Hence, the evaluation of D-dimer blood levels may be useful in clinical practice to predict the involvement of the liver and the prognosis of these patients. This data highlights the fundamental role of coagulation balance in subjects with advanced form of COVID-19.

Sudden death due to fulminant lymphocytic myocarditis with atypical prodromal symptoms.

Diagnosis of myocarditis is complex because it is not always preceded by clear symptoms. We report the case of a woman who died suddenly. Autopsy and histopathological investigations revealed a lymphocytic myocarditis. Clinical history showed the patient went to the hospital some days before for joint pain and low-grade fever.

SARS-CoV-2 Spread Dynamics in Italy: The Calabria Experience.

INTRODUCTION: The first case of infection by SARS-CoV-2 (i.e., COVID-19) has been officially recorded by the Italian National Health Service on February 21st, 2020. Lombardy was the first Italian region to be affected by the pandemic. Subsequently, the entire Northern part of Italy recorded a high number of cases, while the South was hit following the migratory waves. On March 8th, the Italian Government has issued a decree that imposed a total lockdown, defining it as a state of isolation and restricting access in Lombardy and the other 14 provinces of Northern Italy. METHODS: We analyzed the virus trend in the period between February 24th and September 8th, 2020, focusing on Calabria, with regards to the following items: new positives, change of total positives, and total cases. Furthermore, we included other information, such as the incubation period, symptom resolution period, quarantine period. RESULTS: On March 27th, the epidemic curve spiked with 101 new positive cases validating the hypothesis that this abnormal event was related to the displacement of non-residents people, living in the Northern part of Italy, to the home regions in the South. The epidemic curve showed a decreasing trend in the period after lockdown, proving the effectiveness of this measure. From the end of the lockdown May 04th to September 8th, the registered trend was -94.51%. A negative growth rate indicates that the number of new positive cases is lower than the number of healed patients. CONCLUSION: This study describes the effectiveness of the Italian Government policy, particularly the role of lockdown, for the containment of SARS-CoV-2 contagion in Calabria, a region with a low SARS-CoV-2 infection rate within the registered period.

Analysis of the persistence time of the SARS-CoV-2 virus in the cadaver and the risk of passing infection to autopsy staff.

The activity of the SARS-CoV-2 virus has not yet been studied in a post-mortem setting. The absence of these data has led to the prohibition of exposure of infected corpses during burial procedures. Our aim was to assess the virus's persistence and the possibility of transmission in the post-mortem phase including autopsy staff. The sample group included 29 patients who were admitted to our Covid-19 Centre who died during hospitalisation and the autopsy staff. All the swabs were subjected to a one-step real-time reverse transcription polymerase chain reaction with cycle threshold (Ct) values. Swab collection was performed at 2 h, 4 h, 6 h, 12 h, over 24 since death. The following were the analysis of patients' swabs: 10 cases were positive 2 h after death; 10 cases positive 4 h after death; 9 cases were found positive 6 h after death; 7 cases positive 12 h after death; 9 cases remained positive 24 h after death. The swabs performed on all the forensic pathologist staff on duty who performed the autopsies were negative. The choice to avoid rituals and the display of corpses before and at the burial procedures given appears cautiously valid due to the persistence of the SARS-CoV-2 virus in the post-mortem period. Although the caution in choosing whether or not to perform an autopsy on infected corpses is acceptable, not to perform autopsies is not biologically supported.

Postmortem Swabs in the Severe Acute Respiratory Syndrome Coronavirus 2 Pandemic: Report on 12 Complete Clinical Autopsy Cases.

CONTEXT.­: Clinical autopsies have historically provided a fundamental contribution in the definition of the clinicopathologic basis of infectious diseases. Even though we are witnessing the decline of the clinical autopsy, its importance remains unchanged as it is the most exhaustive way to investigate diseases. The identification of the virus in postmortem tissues is a fundamental step in the definition of its clinical features. OBJECTIVE.­: To investigate the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in postmortem examination with swabs. DESIGN.­: We performed postmortem swabs in 12 autopsy cases of patients with a clinical diagnosis of SARS-CoV-2-related pneumonia. Our protocol consisted of a rhinopharyngeal and a tracheal swab in order to search for the virus in the upper airways, and of 2 swabs on the parenchyma of each lung. We also performed a fifth swab on the parenchyma of both lungs in order to search for other viruses that could evolve in a clinical picture of interstitial pneumonia. RESULTS.­: Overall, we found 9 of 12 cases had at least 1 postmortem swab positive for SARS-CoV-2. Moreover, we evaluated the time between the antemortem and postmortem swabs, the time between death and the postmortem swabs, and the time between the postmortem swabs and acceptance to the microbiology laboratory. Of note, we did not find a relationship between the results of the swabs and either the time elapsed from their collection or the time elapsed before their acceptance in the microbiology laboratory. CONCLUSIONS.­: A thorough knowledge of the eventual persistence of pathogens in deaths related to infectious diseases is fundamental for the safety of the operators during the autopsy practice, especially when referring to emergent pathogens, such as SARS-CoV-2. Our study highlights the importance in performing multiple swabs in the postmortem examination, because SARS-CoV-2 swab positivity can be limited to only a single swab.

Severe Acute Respiratory Syndrome Coronavirus 2 Pandemic.

CONTEXT.­: The novel coronavirus disease 2019 (COVID-19) pandemic is significantly changing methodologic approaches in all branches of the health system. From a forensic point of view, this event is partly changing the manner in which forensic pathologists and all those who work in autopsy services operate, but above all, it is changing the patterns established for years by which cadavers are analyzed postmortem. OBJECTIVE.­: To present a review of the literature and a proposal for COVID-19 autopsy protocols. To contain the infection risk, a revision of all the protocols that until now have been applied to the examination of bodies that require autopsy services is required. DATA SOURCES.­: Currently, the diagnosis and postmortem analysis of positive or suspected COVID-19 cases plays a crucial role in scientific research. A review of the main recommendations proposed by international scientific societies regarding the risk of infection during autopsy was carried out. Scientific papers currently available via the PubMed NCBI search engine on COVID-19 postmortem diagnosis were also examined. CONCLUSIONS.­: Throughout the history of medicine, autopsy has been fundamental to the understanding of multiple pathogenic processes that are investigated postmortem. The purpose of the study is to propose an operating protocol that can be useful for all clinical and forensic autopsies, with particular reference to the correct methods to be applied to the examination of positive or suspected COVID-19 cases, regarding both the autopsy procedure and the collection and analysis of biological samples.

Gut Microbiota and Liver Interaction through Immune System Cross-Talk: A Comprehensive Review at the Time of the SARS-CoV-2 Pandemic.

BACKGROUND AND AIMS: The gut microbiota is a complex ecosystem containing bacteria, viruses, fungi, yeasts and other single-celled organisms. It is involved in the development and maintenance of both innate and systemic immunity of the body. Emerging evidence has shown its role in liver diseases through the immune system cross-talk. We review herein literature data regarding the triangular interaction between gut microbiota, immune system and liver in health and disease. METHODS: We conducted a search on the main medical databases for original articles, reviews, meta-analyses, randomized clinical trials and case series using the following keywords and acronyms and their associations: gut microbiota, microbiome, gut virome, immunity, gastrointestinal-associated lymphoid tissue (GALT), non-alcoholic fatty liver disease (NAFLD), non-alcoholic steato-hepatitis (NASH), alcoholic liver disease, liver cirrhosis, hepatocellular carcinoma. RESULTS: The gut microbiota consists of microorganisms that educate our systemic immunity through GALT and non-GALT interactions. The latter maintain health but are also involved in the pathophysiology and in the outcome of several liver diseases, particularly those with metabolic, toxic or immune-mediated etiology. In this context, gut virome has an emerging role in liver diseases and needs to be further investigated, especially due to the link reported between severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection and hepatic dysfunctions. CONCLUSIONS: Changes in gut microbiota composition and alterations in the immune system response are involved in the pathogenesis of metabolic and immune-mediated liver diseases.

The silent deaths of the elderly in long-term care facilities during the Covid-19 pandemic: The role of forensic pathology.

The Covid-19 pandemic is currently a major global public health problem. We know that the elderly and people with chronic diseases contract the infection more easily and they develop clinically more serious and often lethal forms. To date, the reasons for this have been generically attributed to old age and underlying diseases. Most Covid-19 deaths occurred in long-term care facilities because the residents are elderly people with chronic illness living in close contact. Therefore, facilities have become epidemic outbreaks. Forensic knowledge is very limited because an autopsy is rarely performed. Post-mortem investigations can help increase knowledge about Covid-19 and identify any undiagnosed pathologies in life. Therefore, forensic investigations play a role in protecting a frail population. Autopsies should be encouraged on elderly people who died of Covid-19.

The role of the COVID-19 pandemic as a risk factor for suicide: What is its impact on the public mental health state today?

The phenomenon of suicide is a much studied but still little-known issue. In this particular period of health emergency, quarantine and mandatory restrictions could play a role in the genesis of fatal events or suicide attempts not only in people at risk. However, this issue has not yet been adequately addressed in the literature. The influence of the global pandemic could change the way suicide cases are analyzed; in the future, it is necessary to reconsider and analyze the various risk groups by population but above all to evaluate new methods of intervention for avoiding the increase in fatal events related to the current emergency whose duration is still unknown.

The impact of the Covid-19 pandemic on domestic violence: The dark side of home isolation during quarantine.

Domestic violence is a global public health problem. It takes many different forms and leads to significant physical and psychological consequences for the victim and the whole family. Situations that may prompt episodes of violence in the family include stress, emotional disappointment, economic factors, bad and cramped housing, and alcohol or drug abuse. How does the government's forced home isolation to contain Covid-19 infections impact on this type of abuse? Numerous articles have reported a decrease in reports of domestic violence since quarantine began but how reliable is these data? Is it a potential wake-up call for public institutions? We discuss the risks associated with quarantine measures during the pandemic and suggest the measures to prevent and improve the reporting of abuse cases.

Quarantine of the Covid-19 pandemic in suicide: A psychological autopsy

The epidemiology of suicide has identified numerous psychiatric and occupational risk factors. The circumstances surrounding a suicide are fundamental to determining whether its characteristics will play a crucial role in the decision-making process. The state of emergency arising from the Covid-19 pandemic has introduced a new element, given the general concern and feelings of alarm which are global. The most suitable forensic method to analyse these cases is the psychological autopsy. This study's purpose is to analyse the application of the psychological autopsy method to evaluate the impact of the pandemic where government lockdowns impose restrictions on personal freedom. We set out to consider how far this together with other factors may induce suicide. The literature does not as yet offer us a retrospective analysis of the influence of the global pandemic state on rates of suicide. Accordingly, we report a forensic case and examine the critical issues and problems in the management of these cases.
