Resolving the developmental mechanisms of cardiac microthrombosis of SARS-CoV-2 based on single-cell transcriptome analysis

The coronavirus disease 2019（COVID-19） outbreak caused by the severe acute respiratory syndrome coronavirus-2（SARS-CoV-2） developed into a global health emergency. Systemic microthrombus caused by SARS-CoV-2 infection is a common complication in patients with COVID-19. Cardiac microthrombosis as a complication of SARS-CoV-2 infection is the primary cause of cardiac injury and death in patietns with severe COVID-19. In this study, we performed single-cell sequencing analysis of the right ventricular free wall tissue from healthy donors,patients who died during the hypercoagulable period of characteristic coagulation abnormality（CAC）, and patients who died during the fibrinolytic period of CAC. We collected 61,187 cells enriched in 24 immune cell subsets and 13 cardiac-resident cell subsets. We found that in the course of SARS-CoV-2 infected heart microthrombus, MYO1EhighRASGEF1Bhighmonocyte-derived macrophages promoted hyperactivation of the immune system and initiated the extrinsic coagulation pathway by activating chemokines CCL3, CCL5. This series of events is the main cause of cardiac microthrombi following SARS-CoV-2 infection. In a SARS-CoV-2 infected heart microthrombus, excessive immune activation is accompanied by an increase in cellular iron content, which in turn promotes oxidative stress and intensifies intercellular competition. This induces cells to alter their metabolic environment, resulting in increased sugar uptake via the glycosaminoglycan synthesis pathway. In addition, high levels of reactive oxygen species generated by elevated iron levels promote increased endogenous malondialdehyde synthesis in a subpopulation of cardiac endothelial cells. This exacerbates endothelial cell dysfunction and exacerbates the coagulopathy process.

Background:Hepatocellular carcinoma (HCC) is the most common cause of cancer-related death in Saudi Arabia. Our study aimed to investigate the patterns of HCC and the effect of TNM staging, Alfa-fetoprotein (AFP), and Child-Turcotte Pugh (CTP) on patients' overall survival (OS).Methods:A retrospective analysis was conducted on 43 HCC patients at a single oncology center in Saudi Arabia from 2015 to 2020. All patients had to fulfill one of the following criteria: (a) a liver lesion reported as definitive HCC on dynamic imaging and/or (b) a biopsy-confirmed diagnosis.Results:The mean patient age of all HCC cases was 66.8 with a male-to-female ratio of 3.3:1. All patients were stratified into two groups: viral HCC (n = 22, 51%) and non-viral HCC (n = 21, 49%). Among viral-HCC patients, 55% were due to HBV and 45% due to HCV. Cirrhosis was diagnosed in 79% of cases. Age and sex did not significantly statistically differ in OS among viral and non-viral HCC patients (-value > 0.05). About 65% of patients had tumor size >5 cm during the diagnosis, with a significant statistical difference in OS (-value = 0.027). AFP was >400 ng/ml in 45% of the patients. There was a statistically significant difference in the OS in terms of AFP levels (-value = 0.021). A statistically significant difference was also observed between the CTP score and OS (-value = 0.02). CTP class B had the longest survival. BSC was the most common treatment provided to HCC patients followed by sorafenib therapy. There was a significant statistical difference in OS among viral and non-viral HCC patients (-value = 0.008).Conclusions:The most common predictors for OS were the underlying cause of HCC, AFP, and tumor size. Being having non-viral etiology, a tumor size >5 cm, an AFP > 400 ng/mL, and a CTP score class C were all negatively associated with OS.

Entecavir as treatment for reactivation of hepatitis B in immunosuppressed patients

引用

World Journal of Gastroenterology 2010年第43期16卷 5447-5451页

作者： Sylvia Brost Paul Schnitzler Wolfgang Stremmel Christoph Eisenbach department of Gastroenterology and infectious diseases University of Heidelberg department of infectious diseases Virology University of Heidelberg

AIM: To study the efficacy and safety of entecavir (ETV) as first-line therapy for hepatitis B virus (HBV) reactivation due to immunosuppression. METHODS: Four patients that were treated with different immunosuppressive regimens for hematological malignancies, who presented with HBV reactivation were treated with ETV. Clinical outcome, biochemical and virological factors, including quantitative hepatitis B surface antigen (HBsAg) were studied. RESULTS: In all patients, ETV induced suppression of HBV, and rapid clinical improvement without side effects. In one patient with an alanine aminotransferase (ALT) flare, tenofovir was added after 3 mo of treatment. Until death from disease progression at 6 mo after treatment initiation, this patient did not clear HBV infection. Retrospectively, it is highly probable that thepatient had been non-adherent. In the other three patients, the virological responses were associated with an expeditious decrease in quantitative HBsAg titers with negativity after 2 mo, and all three had HBsAg seroconversion. In one patient, HBV DNA reached a plateau after 3 mo, before becoming undetectable after 1 year, despite early ALT normalization and undetectable quantitative HBsAg. CONCLUSION: ETV seems to be effective and safe treatment for HBV reactivation. Monitoring of quantitative HBsAg might be an additional useful tool to monitor treatment response.
