| 1 | Unique immunological profile in patients with COVID-19显示文摘The relationship between severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)and host immunity is poorly understood.We performed an extensive analysis of immune responses in 32 patients with severe COVID-19,some of whom succumbed A control population of healthy subjects was included.Patients with COVID-19 had an altered distribution of peripheral blood lymphocytes,with an increased proportion of mature natural killer(NK)cells and low T-cell numbers.NK cells and CD8^(+)T cells overexpressed T-cellimmunoglobulin and mucin domain-3(TIM-3)and CD69.NK cell exhaustion was attested by increased frequencies of programmed cell death protein 1(PD-1)positive cells and reduced frequencies of natural killer group 2 member D(NKG2D)-,DNAX accessory molecule-1(DNAM-1)-and sialic acid-binding Ig-like lectin 7(Siglec-7)-expressing NK cells,associated with a reduced ability to secrete interferon(IFN)γ.Patients with poor outcome showed a contraction of immature CD56^(bright) and an expansion of mature CD57^(+)F_(CEI)Rlγ^(eng) adaptive NK cells compared to survivors.Increased serum levels of IL-6 were also more frequently identified in deceased patients compared to survivors.Of note,monocytes secreted abundant quantities of IL-6,IL-8,and IL-1β which persisted at lower levels several weeks after recovery with concomitant normalization of CD69,PD-1 and TIM-3 expression and restoration of CD8^(+)T cell numbers.A hyperactivated/exhausted immune response dominate in severe SARS-CoV-2 infection,probably driven by an uncontrolled secretion of inflammatory cytokines by monocytes.These findings unveil a unique immunological profile in COVID-19 patients that will help to design effective stage-specific treatments for this potentially deadly disease. | Stefania Varchetta Dalila Mele Barbara Olivier Stefania Mantovani Serena Ludovisi Antonella Cerino Raffaele Bruno Alberto Castelli Mario Mosconi Marco Vecchia Silvia Roda Michele Sachs Catherine Klersy Mario U.Mondelli | 2021 | Cellular & Molecular Immunology2021，18，3： | 1 |

| 3 | Factors associated with success of telaprevir-and boceprevir-based triple therapy for hepatitis C virus infection显示文摘AIM To evaluate new therapies for hepatitis C virus(HCV), data about real-world outcomes are needed.METHODS Outcomes of 223 patients with genotype 1 HCV who started telaprevir-or boceprevir-based triple therapy(May 2011-March 2012) at the Mount Sinai Medical Center were analyzed. Human immunodeficiency viruspositive patients and patients who received a liver transplant were excluded. Factors associated with sustained virological response(SVR24) and relapse were analyzed by univariable and multivariable logistic regression as well as classification and regression trees. Fast virological response(FVR) was defined as undetectable HCV RNA at week-4(telaprevir) or week-8(boceprevir). RESULTS The median age was 57 years, 18% were black, 44% had advanced fibrosis/cirrhosis(FIB-4 ≥ 3.25). Only 42%(94/223) of patients achieved SVR24 on an intention-totreat basis. In a model that included platelets, SVR24 was associated with white race [odds ratio(OR) = 5.92, 95% confidence interval(CI): 2.34-14.96], HCV sub-genotype 1b(OR = 2.81, 95%CI: 1.45-5.44), platelet count(OR = 1.10, per x 104 cells/μL, 95%CI: 1.05-1.16), and IL28 B CC genotype(OR = 3.54, 95%CI: 1.19-10.53). Platelet counts > 135 x 103/μL were the strongest predictor of SVR by classification and regression tree. Relapse occurred in 25%(27/104) of patients with an end-oftreatment response and was associated with non-FVR(OR = 4.77, 95%CI: 1.68-13.56), HCV sub-genotype 1a(OR = 5.20; 95%CI: 1.40-18.97), and FIB-4 ≥ 3.25(OR = 2.77; 95%CI: 1.07-7.22). CONCLUSION The SVR rate was 42% with telaprevir-or boceprevirbased triple therapy in real-world practice. Low platelets and advanced fibrosis were associated with treatment failure and relapse. | Kian Bichoupan Neeta Tandon Valerie Martel-Laferriere Neal M Patel David Sachs Michel Ng Emily A Schonfeld Alexis Pappas James Crismale Alicia Stivala Viktoriya Khaitova Donald Gardenier Michael Linderman William Olson Ponni V Perumalswami Thomas D Schiano Joseph A Odin Lawrence U Liu Douglas T Dieterich Andrea D Branch | 2017 | World Journal of Hepatology2017，9，11： | 0 |
