SN Comprehensive Clinical Medicine
Currently, the coronavirus disease 2019 (COVID-19) is the priority of the global health agenda. Since the first case was reported in Wuhan, China, this infection has continued to spread and has been considered as a pandemic by the World Health Organization (WHO) within 3 months of its outbreak. Several studies have been done to better understand the pathogenesis and clinical aspects of the disease. It appears that COVID-19 affects almost all body organs due to the direct effect of the virus and its induced widespread inflammatory response. This multi-systemic aspect of the disease has to be inculcated in COVID-19 management by health providers to improve patient outcomes. This strategy could help curb the burden of the disease especially in low-and middle-income countries (LMICs) like most African countries where the pandemic is at an "embryonic" stage.
Neurological Sequelae in Patients with COVID-19: A Histopathological Perspective
International Journal of Environmental Research and Public Health
Background: Neuroinvasive properties of SARS-CoV-2 have allowed the hypothesis of several pathogenic mechanisms related to acute and chronic neurological sequelae. However, neuropathological correlates have been poorly systematically investigated, being retrieved from reports of single case or limited case series still. Methods: A PubMed search was carried out to review all publications on autopsy in subjects with “COronaVIrus Disease-19” (COVID-19). Among them, we focused on histological findings of the brain, which were compared with those from the authors’ autoptic studies performed in some COVID-19 patients. Results: Only seven studies reported histological evidence of brain pathology in patients deceased for COVID-19, including three with reverse transcription–quantitative polymerase chain reaction evidence of viral infection. All these studies, in line with our experience, showed vascular-related and infection-related secondary inflammatory tissue damage due to an abnormal imm...
Autopsy findings in COVID-19 infection-related death: a systematic review
Egyptian Journal of Forensic Sciences
Introduction Coronavirus-19 disease (COVID-19) has been declared as pandemic by the World Health Organization (WHO) in March 2020. As of 28 November 2021, there were more than 260 million cases and nearly 5.2 million deaths caused by COVID-19. The most affected system by COVID-19 infection was the respiratory system although several other studies suggested multi-organ involvement with pathophysiology that was not clearly understood. Autopsy findings were beneficial to researchers to determine the mechanism behind these organ failures. The objective of this review was to summarize the autopsy findings related to COVID-19 death. Method Online literature search was conducted via online databases such as Scopus, PubMed and Google Scholar. The keywords inputted during the search were “post-mortem”, “autopsy” and “COVID-19” in title, abstract and keywords. The inclusion criteria were the topic related with the title of this review, published in 2020–2021, have full text available and in E...
COVID-19 and myocarditis: a systematic review and overview of current challenges
Heart Failure Reviews
Myocardial inflammation in COVID-19 has been documented. Its pathogenesis is not fully elucidated, but the two main theories foresee a direct role of ACE2 receptor and a hyperimmune response, which may also lead to isolated presentation of COVID-19-mediated myocarditis. The frequency and prognostic impact of COVID-19-mediated myocarditis is unknown. This review aims to summarise current evidence on this topic. We performed a systematic review of MEDLINE and Cochrane Library (1/12/19–30/09/20). We also searched clinicaltrials.gov for unpublished studies testing therapies with potential implication for COVID-19-mediated cardiovascular complication. Eligible studies had laboratory confirmed COVID-19 and a clinical and/or histological diagnosis of myocarditis by ESC or WHO/ISFC criteria. Reports of 38 cases were included (26 male patients, 24 aged
Review on Pathogenesis of Various Comorbidities in COVID-19 and Homoeopathic Immunomodulation
2020
Background: COVID -19 infection has already became pandemic with a heightened mortality. The emerging data suggest that there is an increased association of COVID-19 with comorbidities. The aim of this study was to understand the association between various comorbidities and COVID-19, probable pathophysiological mechanism leading to direct and indirect damage of the system and also to find whether Homoeopathy can offer anything at the pathogenetic level for controlling the infection. Methods: A systematic search on all the available relevant articles and research publications in the English language was made on Pub Med database and Google Scholar using the Mesh key words ‘COVID-19’, ‘comorbidities’, ‘diabetes ‘, ‘hypertension’, ‘cardiovascular disease’, ‘kidney’, ‘pathogenesis’ till June 7 2020. Result: The probable pathophysiological mechanism of various comorbidities in COVID-19 were analysed. The expression of ACE2 in various locations can be considered as the main determinant of...
Corona Virus Infectious Disease 19 (COVID-19) in Various Reviews
Systematic Reviews in Pharmacy, 2020
The current COVID-19 outbreak was caused by a new coronavirus, SARS-CoV-2. It accesses host cells through the angiotensin-converting enzyme 2 (ACE2) protein, which is expressed by endothelial cells (EC) and very abundantly expressed in the lungs. SARS-CoV-2 uses a surface glycoprotein (peplomer) called a spike to access host cells and ACE2 has been revealed to be a co-receptor for coronavirus entry. The antigen presentation of SARS-CoV mainly depends on the MHC I molecule, but MHC II also contributes to the presentation. Based on the mechanism of a common acute viral infection, the antibody profile against the SARS-CoV virus contains characteristic pattern of IgM and IgG production. By the end of week 12, SARS-specific IgM antibodies disappear, whereas IgG antibodies can last in a longer period of time, which shows IgG antibodies can mainly hold a protective role, and SARS-specific IgG antibodies mainly are S-specific and N-specific antibodies. Clinical manifestations are not only f...
Interplay of COVID-19 and cardiovascular diseases in Africa: an observational snapshot
Clinical Research in Cardiology
The COVID-19 pandemic, which started around December 2019 has, at present, resulted in over 450,000 deaths globally, and approximately 1% of these deaths have been reported in Africa. Despite the high prevalence of COVID-19 risk factors, namely: hypertension, diabetes, chronic pulmonary disease, cardiovascular diseases (CVDs) such as rheumatic heart disease, compromised immunity and obesity, low case fatality rates have been recorded in many parts of Africa so far. COVID-19 severity has previously been shown to be worse in patients with CVD and hypertension. We observed the severity of COVID-19 and mortality rates in Africa, and compared outcomes with prevalence of established risk factors (hypertension and CVD). We stratified data as per the United Nations' 5 African subregions. North African countries show a positive association between the risk factors and the mortality rates from COVID-19. However, we observed discordant patterns in the relationship between COVID-19, and either CVD or hypertension, in sub-Saharan African countries. In this paper, we also review the pathogenesis of SARS-CoV-2 infection and how it worsens CVD and postulate that the differences in modulation of the renin-angiotensin-aldosterone system (RAAS) axis which controls angiotensin-converting enzyme (ACE)/ACE2 balance may be an important determinant of COVID-19 outcomes in Africa.
Lung histopathological findings in COVID-19 disease – a systematic review
Infectious Agents and Cancer
Since December 2019, the global burden of the COVID-19 pandemic has increased rapidly and has impacted nearly every country in the world, affecting those who are elderly or with underlying comorbidities or immunocompromised states. Aim of this systematic review is to summarize lung histopathological characteristics of COVID-19, not only for diagnostic purpose but also to evaluate changes that can reflect pathophysiological pathways that can inform clinicians of useful treatment strategies. We identified following histopathological changes among our patients:: hyaline membranes; endothelial cells/ interstitial cells involvement; alveolar cells, type I pneumocytes/ type II pneumocytes involvement; interstitial and/ or alveolar edema; evidence of hemorrhage, of inflammatory cells, evidence of microthrombi; evidence of fibrin deposition and of viral infection in the tissue samples.The scenario with proliferative cell desquamation is typical of Acute Respiratory Distress Syndrome (ARDS) ...
Children
Cardiac involvement in multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus-19 disease is often observed with a high risk of heart failure. The aim is to describe cardiovascular involvement, management and early outcome in MIS-C by comparing cardiovascular manifestations in children younger and older than 6 years old. This retrospective observational study included 25 children with MIS-C, admitted to a single pediatric center between March 2020 and September 2021. The median age was 5 years (13 patients under 6 years and 12 over 6 years); coronary artery abnormalities were observed in 77% of preschoolers, with small and medium aneurysms in half of the cases and two cases of mild ventricular dysfunction. School-age children presented myopericardial involvement with mild to moderate ventricular dysfunction in 67% of cases, and two cases of transient coronary dilatation. There was a significant NT-pro-BNP and inflammatory markers increase in 25 of the patie...
