COVID-19 patients with hypertension under potential risk of worsened organ injuries

Abstract COVID -19 has rapidly spread from Wuhan to worldwide, and now has become a global health concern. Hypertension is the most common chronic illness in COVID-19, while the influence on those patients have not been well described. In this retrospective study, 82 confirmed patients with COVID-19 were enrolled, with epidemiological, demographic, clinical, laboratory, radiological, and therapies data analyzed and compared between COVID-19 patients with (29 cases) or without (53 cases) hypertension. Of all 82 patients with COVID-19, the median age of all patients was 60.5 years, including 49 females (59.8%) and 33 (40.2%) males. Hypertension (31[28.2%]) was the most chronic illness, followed by diabetes (16 [19.5%]) and cardiovascular disease (15 [18.3%]). Common symptoms included fatigue (55[67.1%]), dry cough (46 [56.1%]) and fever (≥37.3℃ (46 [56.1%]). The median time from illness onset to positive outcomes of RT-PCR analysis were 13.0 days, ranging from 3-25 days. In hypertension group, 6 (20.7%) patients died compared to 5 (9.4%) died in non-hypertension group. More hypertension patients with COVID-19 (8 [27.6%]) had at least one coexisting disease than those of non-hypertension patients (2 [3.8%]) (P=0.002). Compared with non-hypertension patients, higher levels of neutrophil counts, serum amyloid A, C-reactive protein, and NT-proBNP were observed in hypertension group, whereas levels of lymphocyte count and eGFR were decreased. Dynamic observations displayed more significant and worsened outcomes in hypertension group after hospital admission. COVID-19 patients with hypertension take more risks of severe inflammatory reactions, worsened internal organ injuries, and deteriorated progress.

AbstractIn less than 6 months, COVID-19 spread rapidly around the world and became a global health concern. Hypertension is the most common chronic disease in COVID-19 patients, but its impact on these patients has not been well described. In this retrospective study, 82 patients diagnosed with COVID-19 were enrolled, and epidemiological, demographic, clinical, laboratory, radiological and therapy-related data were analyzed and compared between COVID-19 patients with (29 cases) or without (53 cases) hypertension. The median age of the included patients was 60.5 years, and the cohort included 49 women (59.8%) and 33 (40.2%) men. Hypertension (31 [28.2%]) was the most common chronic illness, followed by diabetes (16 [19.5%]) and cardiovascular disease (15 [18.3%]). The most common symptoms were fatigue (55 [67.1%]), dry cough (46 [56.1%]) and fever ≥ 37.3 °C (46 [56.1%]). The median time from illness onset to positive RT-PCR test was 13.0 days (range 3–25 days). There were 6 deaths (20.7%) in the hypertension group and 5 deaths (9.4%) in the nonhypertension group, and more hypertensive patients with COVID-19 (8 [27.6%]) than nonhypertensive patients (2 [3.8%]) (P = 0.002) had at least one comorbid disease. Compared with nonhypertensive patients, hypertensive patients exhibited higher neutrophil counts, serum amyloid A, C-reactive protein, and NT-proBNP and lower lymphocyte counts and eGFR. Dynamic observations indicated more severe disease and poorer outcomes after hospital admission in the hypertension group. COVID-19 patients with hypertension have increased risks of severe inflammatory reactions, serious internal organ injury, and disease progression and deterioration.

Abstract Objectives: To investigate the clinical and chest CT characteristics of medical personnel infected with the Coronavirus Disease-2019 (COVID-19).Methods: The clinical, laboratory test and computed tomography (CT) features of 30 medical personnel (MP group, 26-65 years, 16 males) with COVID-19 were retrospectively analyzed, and compared to 33 non-medical related patients (non-MP group, 26-74 years, 19 males). Follow-up CT characteristics were analyzed to assess the changes of the COVID-19 infection in the period of hospitalization.Results: At admission, the main complaints of MP group, including fever (86.7%), fatigue (53.3%) and cough (43.3%), were similar to the non-MP group; the C-reactive protein, erythrocyte sedimentation rate and lactate dehydrogenase levels of the non-MP group (55.6±45.9mg/L, 34.7±26.3mm/H and 321±117U/L) were higher than that of the MP group (17.8±19.9mg/L, 18.6±21.3mm/H and 219±54.2U/L, respectively, all p<0.05). Ground-grass opacities, consolidation, interstitial thickening were common CT features of both groups. The days from illness onset to the first CT exam, and the severity of opacities on initial CT were less in the MP group than that of the non-MP group (p<0.05). However, the days from onset to observation of the most obvious pulmonary opacities, according to CT findings, were similar in the MP group (11.5±5.9 days) and the non-MP group (12.2±3.1 days, p=0.55).Conclusions: Like the general population, medical personnel are also susceptible to the COVID-19, although with more professional knowledge and protective equipment. Occupational exposure is a very important factor. Medical personnel have a higher vigilance about the infection in the early stage of the disease.

BACKGROUND:In recent outbreak of COVID-19 infection,the risk of thrombosis should be concerned.We observed dynamic changes of D-Dimer level,C-Reactive Protein(CRP) level and Venous Thromboembolism risk assessment score(VTE score) during active disease.We included patients of conrmed covid-19 patients who were RT-PCR positive and patients of community acquired pneumonia(CAP) who were conrmed by CT-SCAN ndings.We observed correlation of D-dimer level with both CRP level & VTE score. METHOD:We examined the clinical laboratory result of 50 patients with conrmed COVID-19 positive patients and 50 patients with community acquired pneumonia(CAP).We analysed D-dimer level of this patients by Automated Coagulometer-STAGO in our hematological laboratory and CRP level by latex method.We use pauda prediction score to identify patients at high risk for venous thrombo embolism.We observed D-dimer level of all patients with their correlation to CRP level & VTE score.S RESULT:On admission,Both COVID-19 and CAP patients,D-dimer level were increased,more increased in COVID-19 patient compare to CAP patient. D-dimer level were related to inammatory marker,mainly with CRP level.There was low correlation between VTE score & Ddimer levels weakened the role of D-dimer in the prediction of thrombosis. CONCLUSION:Elevated baseline D-dimer levels are associated with inammation but not with VTE score in COVID patients,So we can't judge whether anticoagulation is needed only according to D-dimer levels. Abnormal D-dimer level with inammatory factors suggest that anticoagulant therapy might be needed.

Interactions of CRP with various substrates in the presence of human serum have been shown to result in efficient activation of C components C1-C5. We now report the ability of CRP to initiate C-dependent hemolysis. For this purpose CRP was isolated by affinity chromatography using pneumococcal CPS and gel filtration; its purity was established by several criteria. Erythrocytes were coated with CPS (E-CPS) and passively sensitized with CRP. C-dependent lysis of these cells was observed upon the addition of suitably absorbed human serum, and the efficiency of hemolysis compared favorably with that initiated by rabbit IgG anti-CPS antibody. CRP also sensitized E-CPS for lysis by guinea pig C; partial lysis was seen when C4-deficient guinea pig serum was used, suggesting that CRP also shares with antibody the ability of CRP to fully activate the C system and provide further evidence for a role for CRP similar to that of antibody in the initiation and modulation of inflammatory reactions via the complete system.

Regulatory T cells (Tregs) participate in the negative regulation of inflammatory reactions by suppressing effector cells. In a number of autoimmune disorders, the suppressive function and/or the number of Tregs is compromised. The lack of active functioning Tregs can be restored with adoptive transfer of expanded ex vivo autologous Tregs. In our study, we traced the differentiation and maturation of Tregs CD4+CD25+FoxP3+CD127low over 7 days of cultivation from initial CD4+ T cells under ex vivo conditions. The resulting ex vivo expanded cell population (eTregs) demonstrated the immune profile of Tregs with an increased capacity to suppress the proliferation of target effector cells. The expression of the FoxP3 gene was upregulated within the time of expansion and was associated with gradual demethylation in the promotor region of the T cell-specific demethylation region. Real-time RT-PCR analysis revealed changes in the expression profile of genes involved in cell cycle regulation. In addition to FOXP3, the cells displayed elevated mRNA levels of Ikaros zinc finger transcription factors and the main telomerase catalytic subunit hTERT. Alternative splicing of FoxP3, hTERT and IKZF family members was demonstrated to be involved in eTreg maturation. Our data indicate that expanded ex vivo eTregs develop a Treg-specific phenotype and functional suppressive activity. We suggest that eTregs are not just expanded but transformed cells with enhanced capacities of immune suppression. Our findings may influence further development of cell immunosuppressive therapy based on regulatory T cells.

Inflammatory Reactions

Tooth eruption is characterized by a coordinated complex cascade of cellular and molecular events that promote tooth movement through the eruptive pathway. During tooth eruption, the stratum intermedium structurally changes to the papillary layer with tooth organ development. We previously reported intercellular adhesion molecule-1 (ICAM-1) expression on the papillary layer, which is the origin of the ICAM-1-positive junctional epithelium. ICAM-1 expression is induced by proinflammatory cytokines, including interleukin-1 and tumor necrosis factor. Inflammatory reactions induce tissue degradation. Therefore, this study aimed to examine whether inflammatory reactions are involved in tooth eruption. Reverse transcription-polymerase chain reaction (RT-PCR) analysis revealed sequential expression of hypoxia-induced factor-1α, interleukin-1β, and chemotactic factors, including keratinocyte-derived chemokine (KC) and macrophage inflammatory protein-2 (MIP-2), during tooth eruption. Consistent with the RT-PCR results, immunohistochemical analysis revealed KC and MIP-2 expression in the papillary layer cells of the enamel organ from the ameloblast maturation stage. Moreover, there was massive macrophage and neutrophil infiltration in the connective tissue between the tooth organ and oral epithelium during tooth eruption. These findings suggest that inflammatory reactions might be involved in the degradation of tissue overlying the tooth organ. Further, these reactions might be induced by hypoxia in the tissue overlying the tooth organ, which results from decreased capillaries in the tissue. Our findings indicate that bacterial infections are not associated with the eruption process. Therefore, tooth eruption might be regulated by innate inflammatory mechanisms.

AbstractDietary recommendations suggest decreased consumption of SFA to minimise CVD risk; however, not all foods rich in SFA are equivalent. To evaluate the effects of SFA in a dairy food matrix, as Cheddar cheese, v. SFA from a vegan-alternative test meal on postprandial inflammatory markers, a randomised controlled cross-over trial was conducted in twenty overweight or obese adults with metabolic abnormalities. Individuals consumed two isoenergetic high-fat mixed meals separated by a 1- to 2-week washout period. Serum was collected at baseline, and at 1, 3 and 6 h postprandially and analysed for inflammatory markers (IL-6, IL-8, IL-10, IL-17, IL-18, TNFα, monocyte chemotactic protein-1 (MCP-1)), acute-phase proteins C-reactive protein (CRP) and serum amyloid-A (SAA), cellular adhesion molecules and blood lipids, glucose and insulin. Following both high-fat test meals, postprandial TAG concentrations rose steadily (P < 0·05) without a decrease by 6 h. The incremental AUC (iAUC) for CRP was significantly lower (P < 0·05) in response to the cheese compared with the vegan-alternative test meal. A treatment effect was not observed for any other inflammatory markers; however, for both test meals, multiple markers significantly changed from baseline over the 6 h postprandial period (IL-6, IL-8, IL-18, TNFα, MCP-1, SAA). Saturated fat in the form of a cheese matrix reduced the iAUC for CRP compared with a vegan-alternative test meal during the postprandial 6 h period. The study is registered at clinicaltrials.gov under NCT01803633.

We defined the acute phase behaviour of a number of rabbit plasma proteins in studies (in vivo) and studied the effects of monokine preparations on their synthesis by rabbit primary hepatocyte cultures. Following turpentine injection, increased serum levels of C-reactive protein, serum amyloid A protein, haptoglobin, ceruloplasmin, and decreased concentrations of albumin were observed. In contrast to what is observed in man, concentrations of alpha 2-macroglobulin and transferrin were increased. Co-culture of primary hepatocyte cultures with lipopolysaccharide-activated human peripheral blood monocytes or incubation with conditioned medium prepared from lipopolysaccharide-activated human or rabbit monocytes resulted in dose-dependent induction of serum amyloid A, haptoglobin, ceruloplasmin and transferrin and depression of albumin synthesis, while C-reactive protein synthesis and mRNA levels remained unchanged. A variety of interleukin-1 preparations induced dose-dependent increases in the synthesis and secretion of serum amyloid A, haptoglobin, ceruloplasmin and transferrin and decreased albumin synthesis. Human recombinant tumour necrosis factor (cachectin) induced a dose-dependent increase in synthesis of haptoglobin and ceruloplasmin. In general, human interleukin-1 was more potent than mouse interleukin-1 and tumour necrosis factor. None of the monokines we studied had an effect on C-reactive protein synthesis or mRNA levels. These data confirm that C-reactive protein, serum amyloid A, haptoglobin and ceruloplasmin display acute phase behaviour in the rabbit, and demonstrate that, in contrast to their behaviour in man, alpha 2M and transferrin are positive acute phase proteins in this species. While both interleukin-1 and tumour necrosis factor regulate biosynthesis of a number of these acute phase proteins in rabbit primary hepatocyte cultures, neither of these monokines induced C-reactive protein synthesis. Comparison of these findings with those in human hepatoma cell lines, in which interleukin-1 does not induce serum amyloid A synthesis, suggests that the effect of interleukin-1 on serum amyloid A synthesis may be indirect.
