    Background: Kidney damage is considered to be one of the risk factors for severity and mortality among COVID-19 patients. However, molecular nature of such observations remains unknown. Hypothesis: Altered gene expressions due to infection MESHD infection and in chronic HP and in chronic kidney disease MESHD could explain severity in COVID-19 with kidney defects. Methods: We collected gene expression data from publicly available resources Gene Expression Omnibus CKD, Enrichr for deregulated genes in SARS-CoV infected cells in vitro, DisGeNET and others and carried out enrichment analysis using Enrichr. Result: Number of common genes altered in chronic kidney disease HP kidney disease MESHD (CKD) and SARS-CoV infected cells was 2834. Enrichment analysis revealed that biological processes related viral life cycle and growth, cytokines, immunity, interferon, inflammation MESHD, apoptosis, autophagy, oxidative stress and others were significantly enriched with common deregulated genes. Similarly, significantly enriched pathways related to viral and bacterial infections MESHD, immunity and inflammation MESHD, cell cycle, ubiquitin mediated proteolysis, signaling pathways like Relaxin signaling pathway, mTOR signaling pathway, IL-17 signaling pathway, NF-kappa B signaling pathway were enriched with the common deregulated genes. These processes and pathways are known to be related to kidney damage. DisGeNET terms enriched include and related to Dengue MESHD fever MESHD fever HP, chronic Hepatitis MESHD chronic Hepatitis HP, measles MESHD, retroviridae infections MESHD, respiratory syncytial virus Infections MESHD and many others. Kidney dysfunction related terms ischemia MESHD of kidney, renal fibrosis HP fibrosis MESHD and diabetic nephropathy MESHD nephropathy HP. Conclusion: Common deregulated genes in SARS-CoV infected cells and chronic kidney disease HP kidney disease MESHD, as well as their enrichment with molecular processes and pathways relevant for viral pathogenesis and renal dysfunctions, could explain the severity of COVID-19 with kidney disease MESHD. This observation not only provides molecular relation of severity in COVID-19 with renal dysfunctions but might also help in the management and treatment targets for these cases.

    Background: Since the Coronavirus Disease MESHD 2019 (COVID-19) outbreak, there is limited data on the clinical characteristics, treatment strategies and prognosis of COVID-19 in patients with concurrent renal disease MESHD. The kidney is believed to have a predisposition for COVID-19 due to its abundant angiotensin-converting enzyme 2 (ACE2) expression, which acts as a cell entry receptor for the severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2). Recent postmortem investigations reveal renal involvement in COVID-19, and case reports describe collapsing glomerulopathy HP in African American patients with COVID-19. However, there is limited data regarding IgA nephropathy HP in the setting of COVID-19.Case presentation: In the present case, we report a 65-year old Chinese woman who presented with macroscopic hematuria HP hematuria MESHD, worsening proteinuria MESHD proteinuria HP and decreased renal function after COVID-19 infection MESHD. She received a renal biopsy during COVID-19 infection MESHD. The renal biopsy revealed IgA nephropathy HP without any evidence for SARS-Cov-2. The findings suggest that the renal abnormalities were a consequence of exacerbation of this patient’s underlying glomerular disease MESHD after COVID-19 infection MESHD. After a regimen of 3-day course of glucocorticoid and angiotensin II receptor blocker therapy, the patient recovered and remained stable upon follow-up. Conclusions: It is important to consider the underlying glomerular disease MESHD exacerbation rather than virus induced injury when dealing with renal abnormalities in patients with COVID-19.

    BackgroundAltered mentation in COVID-19 patients can be a function of any number of metabolic abnormalities associated with the infection MESHD. Here we present the case of an encephalopathic COVID-19 patient with bilateral globus pallidus lesions. While imaging abnormalities involving basal ganglia have been reported in encephalitis MESHD encephalitis HP caused by neuroinvasive flaviviruses, the bipallidal lesions noted here likely resulted from hypoxic-ischemic brain injury MESHD.Case PresentationA 51-year-old African American woman was found unresponsive at home by her fiancé. She had been complaining of shortness of breath and cough MESHD cough HP for three days. She is a former smoker with past medical history of hypertension MESHD hypertension HP, nephropathy HP, and bipolar disorder. Upon examination, she was alert but nonverbal, following commands inconsistently, and unable to move extremities against gravity. After several minutes, she was able to state her name but kept repeating it in response to all questions. Chest radiograph revealed bilateral lung infiltrates. CT of the head showed hypodensities in bilateral globus pallidi. A non-contrast MRI of the brain showed symmetric restricted diffusion and FLAIR hyperintense signal changes in bilateral globus pallidi. Abnormal SWI signal seen in bilateral globus pallidi likely represents mineralization or hemosiderin. There were no striatal or thalamic lesions. Major intracranial arteries were widely patent.The patient later tested positive for 2019-nCoV using real-time PCR assay, and was transferred to our COVID-19 designated hospital campus. Thereafter, she had waxing and waning mentation. Repeat CT imaging 11 days after the first scan demonstrated resolution of the bipallidal hypodensities. The patient was recently discharged to a subacute rehab facility but is still experiencing confusion MESHD confusion HP.ConclusionsAs we come across neurological manifestations of COVID-19, we believe neuroimaging is likely to play an important role in establishing if central nervous system involvement is invariably due to indirect mechanisms such as metabolic or hypoxic-ischemic brain injury MESHD or if direct neuroinvasive disease MESHD is a possibility, as with certain viruses.
