    The clinical features, molecular characteristics, and immune responses of COVID-19 MESHD patients with persistent SARS-CoV-2 infection MESHD are not yet well described. In this study, we investigated the differences in clinical parameters, laboratory indexes, plasma cytokines, and peripheral blood mononuclear cell responses, which were assessed using single-cell RNA-sequencing in patients with non-critical COVID-19 MESHD with long durations (LDs) and short durations (SDs) of viral shedding. Our results revealed that clinical parameters and laboratory indexes, such as c-reactive protein (CRP) HGNC and D-dimer, were comparable between SDs and LDs. Most inflammatory cytokines/chemokines, such as IL-2 HGNC, IL2R HGNC, TNFα HGNC/β, IL1β HGNC, and CCL5 HGNC were present at low levels in LDs. Our single-cell RNA-sequencing revealed a reconfiguration of the peripheral immune cell phenotype in LDs, including decreases in natural killer (NK) cells and CD14+ monocytes and an increase in regulatory T cells (Tregs). Furthermore, most cell subsets in LDs consistently exhibited reduced expression of ribosomal protein (RP) genes, indicating dysfunctions in cytokine/chemokine synthesis, folding, modification, and assembly. Accordingly, the negative correlation between the RP levels and viral shedding duration was validated in an independent cohort of bulk-RNA-sequencing data from 103 non-critical patients, which may help guide clinical management and resource allocation. Moreover, peripheral T and NK cells and memory B cells in LDs likely failed to activate, which contributed to the persistence of viral shedding.

    BackgroundLaboratory abnormalities associated with disease severity and mortality in patients with coronavirus disease 2019 MESHD ( COVID-19 MESHD) have been reported in many observational studies. However, there are significant heterogeneities in patient characteristics and research methodologies in these studies.ObjectivesWe aimed to provide an updated synthesis of the association between laboratory abnormalities MESHD and COVID-19 MESHD prognosis.MethodsWe conducted an electronic search of PubMed, Scopus, Ovid, Willey, Web of Science, and the China National Knowledge Infrastructure (CNKI) for studies reporting hematological, coagulation, inflammatory, and immunological results during hospital admission of COVID-19 MESHD patients with different severities and outcomes.ResultsA total of 64 studies were included in the current meta-analysis, with 8 hematological, 3 coagulation, 5 inflammatory, and 23 immunological variables reported. Of them, white blood cell (WBC) and neutrophil counts ( Neu HGNC), D-dimer level, procalcitonin (PCT), erythrocyte sedimentation rate (ESR), C-reactive protein HGNC ( CRP HGNC), ferretin, serum amyloid A (SAA), interleukins (ILs)–2R, IL-6 HGNC, and IL-10 HGNC were significantly increased in severely ill patients and non-survivors. Meanwhile, non-severely ill patients and survivors presented significantly higher counts of eosinophils, lymphocytes, and CD4+ and CD8+ T cells. A majority of included variables presented with significant heterogeneity, some of which resulted from differing disease severities and ages of included patients.ConclusionsThe current meta-analysis provides a comprehensive and updated synthesis of the association between admission laboratory abnormalities with severity and mortality of COVID-19 MESHD. Our results highlight that increases in the levels of PCT, ESR, CRP HGNC, ferretin, SAA, IL-2R HGNC, IL-6 HGNC, and IL-10 HGNC were associated with disease deterioration, whereas elevated eosinophils, lymphocytes, and T-cell subsets might serve as indicators of favorable outcomes.

    Aim: Abnormal laboratory findings have been shown to be associated with severe COVID-19 MESHD. However, all aspects of this association have not been reviewed systematically. Therefore, the aim of this meta-analysis was to explore crucial laboratory parameters in severe COVID-19 MESHD infection. Methods: We performed the literature review of scientific articles indexed in electronic databases. Scientific search engines were used to perform the electronic literature search. After the removal of duplicates and selection of articles of interest, 30 studies were eligible to include. If heterogeneity was high (I2>50%), a random-effects model was applied to combine the data. Otherwise, a fixed-effects model was used.Results: A total of 5586 individuals were assessed (1555 patients with severe COVID-19 MESHD infection and 3452 with non-severe infection). Platelets, lymphocytes and serum albumin were significantly lower in severe patients while other biochemical and immunological parameters including prothrombin time, ALT, AST HGNC, total bilirubin, LDH, procalcitonin, CRP HGNC, IL-6 HGNC, and IgA were significantly higher in patients with severe infection. Neutrophil and monocyte counts as well as hemoglobin level, D-dimer, hypersensitive troponin I, IL-2R HGNC, IgG and IgM levels were different between two groups; however, the difference was not statistically significant (All P-values >0.05). Conclusions: Lymphopenia MESHD, elevated liver enzymes, and high levels of inflammatory biomarkers are associated with severe COVID-19 MESHD infection.

    Aim: The new coronavirus pneumonia MESHD ( COVID-19 MESHD) outbreaking at the end of 2019 is highly contagious. Crude mortality rate reached 49% in critical patients. Inflammation matters MESHD on disease progression. This study analyzed blood inflammation MESHD indicators among mild, severe and critical patients, helping to identify severe or critical patients early. Methods: In this cross-sectional study, 100 patients were included and divided to mild, severe or critical groups. Correlation of peripheral blood inflammation MESHD-related indicators with disease criticality was analyzed. Cut-off values for critically ill MESHD patients were speculated through the ROC curve. ResultsSignificantly, disease severity were associated with age (R=-0.564, P<0.001), interleukin-2 receptor ( IL2R HGNC) (R=-0.534, P<0.001), interleukin-6 HGNC ( IL-6 HGNC) (R=-0.535, P<0.001), interleukin-8 HGNC ( IL-8 HGNC) (R=-0.308, P<0.001), interleukin-10 HGNC ( IL-10 HGNC) (R=-0.422, P<0.001), tumor MESHD tumor HGNC necrosis MESHD factor ( TNF HGNC) (R=-0.322, P<0.001), C-reactive protein HGNC ( CRP HGNC) (R=-0.604, P<0.001), ferroprotein (R=-0.508, P<0.001), procalcitonin (R=-0.650, P<0.001), white cell counts (WBC) (R=-0.54, P<0.001), lymphocyte counts (LC) (R=-0.56, P<0.001), neutrophil count (NC) (R=-0.585, P<0.001) and eosinophil counts (EC) (R=-0.299, P=0.01). ConclusionWith following parameters such as age >67.5 years, IL2R HGNC >793.5U/mL, CRP HGNC >30.7ng/mL, ferroprotein >2252g/L, WBC>9.5*10^9/L or NC >7.305*10^9/L, the progress of COVID-19 MESHD to critical stage should be closely observed and possibly prevented. Inflammation is closely related to severity of COVID-19 MESHD, and IL-6 HGNC, TNF HGNC and IL-8 HGNC might be promising therapeutic targets.

    Background Since late December, 2019, an outbreak of pneumonia MESHD cases caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, and continued to spread throughout China and across the globe. To date, few data on immunologic features of Coronavirus Disease 2019 MESHD ( COVID-19 MESHD) have been reported. Methods In this single-centre retrospective study, a total of 21 patients with pneumonia MESHD who were laboratory-confirmed to be infected with SARS-CoV-2 in Wuhan Tongji hospital were included from Dec 19, 2019 to Jan 27, 2020. The immunologic characteristics as well as their clinical, laboratory, radiological features were compared between 11 severe cases and 10 moderate cases. Results Of the 21 patients with COVID-19 MESHD, only 4 (19%) had a history of exposure to the Huanan seafood market. 7 (33.3%) patients had underlying conditions. The average age of severe and moderate cases was 63.9 and 51.4 years, 10 (90.9%) severe cases and 7 (70.0%) moderate cases were male. Common clinical manifestations including fever MESHD (100%, 100%), cough (70%, 90%), fatigue MESHD (100%, 70%) and myalgia MESHD (50%, 30%) in severe cases and moderate cases. PaO2/FiO2 ratio was significantly lower in severe cases (122.9) than moderate cases (366.2). Lymphocyte counts were significantly lower in severe cases (7000 million/L) than moderate cases (11000 million/L). Alanine aminotransferase HGNC, lactate dehydrogenase levels, high-sensitivity C-reactive protein HGNC and ferritin were significantly higher in severe cases (41.4 U/L, 567.2 U/L, 135.2 mg/L and 1734.4 ug/L) than moderate cases (17.6 U/L, 234.4 U/L, 51.4 mg/L and 880.2 ug /L). IL-2R HGNC, TNF HGNC- and IL-10 HGNC concentrations on admission were significantly higher in severe cases (1202.4 pg/mL, 10.9 pg/mL and 10.9 pg/mL) than moderate cases (441.7 pg/mL, 7.5 pg/mL and 6.6 pg/mL). Absolute number of total T lymphocytes, CD4+T cells and CD8+T cells decreased in nearly all the patients, and were significantly lower in severe cases (332.5, 185.6 and 124.3 million/L) than moderate cases (676.5, 359.2 and 272.0 million/L). The expressions of IFN-{gamma HGNC} by CD4+T cells tended to be lower in severe cases (14.6%) than moderate cases (23.6%). Conclusion The SARS-CoV-2 infection MESHD may affect primarily T lymphocytes, particularly CD4+T cells, resulting in significant decrease in number as well as IFN-{gamma HGNC} production, which may be associated with disease severity. Together with clinical characteristics, early immunologic indicators including diminished T lymphocytes and elevated cytokines may serve as potential markers for prognosis in COVID-19 MESHD.
