Coronavirus disease 2019 (COVID-19): current status and future perspective. With regard to the aetiology and pathogenesis of SARS, this study has demonstrated extensive pulmonary consolidation; significant pulmonary oedema; localized haemorrhage and necrosis; widespread hyaline membrane formation; a local inflammatory reaction consisting mostly of monocytes, lymphocytes, and plasma cells; desquamation of bronchial and alveolar epithelial cells; numerous multinucleate and mononuclear giant cells in pulmonary alveoli in two cases; and typical viral inclusion bodies in epithelial cells in alveoli in all the three cases. It is widely used as a descriptive histologic term rather than a specific marker for cell injury.

It is an RNA virus, the membrane of which contains two types of glycoprotein, E1 and E2, which bind to the receptors of the sensitive cells and enter by endophagocytosis, replicating entirely in the cytoplasm 5. The frequency and distribution of thinning and disorientation of collagen fibers, myxoid degeneration, and hyaline degeneration suggest that these are early degenerative processes. Overlapping and discrete aspects of the pathology and pathogenesis of the emerging human pathogenic coronaviruses SARS‐CoV, MERS‐CoV, and 2019‐nCoV. In view of the clinical symptoms, the disease was initially referred to as ‘atypical pneumonia’ (AP). 2019 Novel-coronavirus: Cardiovascular Insights about Risk Factors, Myocardial Injury, Therapy and Clinical Implications. The onset of SARS is very acute and sudden. The typical histopathological features of MPEs have been well described, whereas reports of hyaline changes and low cellular variants are rarely published. Copyright © 2003 John Wiley & Sons, Ltd. An acute infectious disease spreading mainly via the respiratory route was first identified in Guangdong, China in November 2002 and was then found in other regions in Asia, North America, and Europe. Systemic toxic changes included degeneration and necrosis of the parenchyma cells in the lung, liver, kidney, heart, and adrenal gland. Hyaline Degeneration.

COVID-19: A challenge for forensic and pathological researchers. We believe that all of these changes most likely result from a complicated process involving (1) disturbed cell metabolism as a result of the release of a large number of viral particles following entry into sensitive cells and rapid replication; (2) intense local vascular reactions; and (3) immune impairment mediated by cellular immunity and cytokine functions 6.

They also have a non‐productive cough and some may have traces of blood in their sputum. Although it is a variant of CV, the SARS virus has the same virological characteristics as CV. The first case was reported around Guangzhou, southern China, but as the disease was unknown at this time, it resulted in severe infections of the medical personnel in the hospital, with an infection rate up to 33%. The lungs, immune organs, and systemic small vessels are the main targets of virus attack, so that extensive consolidation of the lung, diffuse alveolar damage with hyaline membrane formation, respiratory distress, and decreased immune function are the main causes of death. Link/Cite. International Journal of Antimicrobial Agents. If you do not receive an email within 10 minutes, your email address may not be registered, Vasculitis of small veins in the renal interstitial tissue and medulla of the adrenal gland was present with associated infiltration chiefly of monocytes and lymphocytes. Background: Nephrotoxicity is characterized and scored by many parameters such as vacuolization, dilatation, hyaline cast, debris or degeneration in injured renal tissue. Hyaline degeneration involves the presence of homogeneous eosinophilic bands or plaques in the extracellular space, which represent the accumulation of proteinaceous tissue 1. (A) Dissociation of hepatocyte cords. The pulmonary lesions included bilateral extensive consolidation, localized haemorrhage and necrosis, desquamative pulmonary alveolitis and bronchitis, proliferation and desquamation of alveolar epithelial cells, exudation of protein and monocytes, lymphocytes and plasma cells in alveoli, hyaline membrane formation, and viral inclusion bodies in alveolar epithelial cells. The clinicopathological observations of the case are described and analyzed. Hyaline glomerulopathy may occur as a spontaneous and/or treatment-related condition in B6C3F1 mice and a treatment-related condition in F344/N rats. Alveolar epithelial cells were markedly swollen, with expansion of mitochondria and expansion and vacuolation of the endoplasmic reticulum.

In some patients, the clinical symptoms are inconsistent with the degree of pulmonary involvement, in that while their clinical symptoms appear slight, their lung lesions deteriorate progressively. Journal of Neurology, Neurosurgery & Psychiatry.
