Project description:BackgroundMore severe cases of COVID- 19 are more likely to be hospitalized and around one-fifth, needing ICU admission. Understanding the common laboratory features of COVID-19 in more severe cases versus non-severe patients could be quite useful for clinicians and might help to predict the model of disease progression. This systematic review and meta-analysis aimed to compare the laboratory test findings in severe vs. non-severe confirmed infected cases of COVID-19.MethodsElectronic databases were systematically searched in PubMed, EMBASE, Scopus, Web of Science, and Google Scholar from the beginning of 2019 to 3rd of March 2020. Heterogeneity across included studies was determined using Cochrane's Q test and the I2 statistic. We used the fixed or random-effect models to pool the weighted mean differences (WMDs) or standardized mean differences and 95% confidence intervals (CIs).FindingsOut of a total of 3009 citations, 17 articles (22 studies, 21 from China and one study from Singapore) with 3396 ranging from 12 to1099 patients were included. Our meta-analyses showed a significant decrease in lymphocyte, monocyte, and eosinophil, hemoglobin, platelet, albumin, serum sodium, lymphocyte to C-reactive protein ratio (LCR), leukocyte to C-reactive protein ratio (LeCR), leukocyte to IL-6 ratio (LeIR), and an increase in the neutrophil, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, blood urea nitrogen (BUN), creatinine (Cr), erythrocyte Sedimentation Rate (ESR), C-reactive protein (CRP), Procalcitonin (PCT), lactate dehydrogenase (LDH), fibrinogen, prothrombin time (PT), D-dimer, glucose level, and neutrophil to lymphocyte ratio (NLR) in the severe group compared with the non-severe group. No significant changes in white blood cells (WBC), Creatine Kinase (CK), troponin I, myoglobin, IL-6 and K between the two groups were observed.InterpretationThis meta-analysis provides evidence for the differentiation of severe cases of COVID-19 based on laboratory test results at the time of ICU admission. Future well-methodologically designed studies from other populations are strongly recommended.
Project description:AimTo analyze the clinical patterns of new-onset inflammatory arthritis after COVID-19 vaccination among patients without pre-existing rheumatic or autoimmune diseases.MethodCase reports and series of new-onset inflammatory arthritis after COVID-19 vaccination were collected before April 2022. Clinical characteristics including diagnosis, age, gender, vaccine types, time interval between events, joint involvement (poly- or oligo-/monoarthritis), and laboratory data reflecting inflammatory status were sorted and P values between these parameters are calculated with independent sample Student's t test or 2 × 2 Fisher's exact test.ResultsAmong 39 cases with new-onset post-vaccination arthritis including 25 females and 13 males (1 unknown), the most common diagnosis is adult-onset Still's disease (AoSD, 10 cases), and the most common vaccine types are BNT162b2 (16 cases) and AZD-1222 (or ChAdOx1-nCoV19, 15 cases). Sub-analysis reveals that post-vaccination polyarthritis is more common among females (P = .016, by 2 × 2 Fisher's exact test, compared with male patients) and older patients (P = .006, by Student's t test). The C-reactive protein level is significantly higher in cases with post-vaccination inflammatory polyarthritis than oligoarthritis (P = .029), as well as in cases with AoSD than other causes of post-vaccination arthritis (P = .004). However, serum level of erythrocyte sedimentation rate in patients with post-vaccination AoSD are independent of other clinical variables in the analysis.ConclusionNew-onset post-vaccination polyarthritis are more common in females and older patients. Although COVID-19 vaccines may lead to inflammatory arthritis, the benefits of vaccination substantially outweigh the potential risks of such serious adverse effects due to their rarity.
Project description:ObjectivesThis study aimed to evaluate the comorbidities among severe and non-severe COVID-19 patients in Asian versus non-Asian populations.DesignSystemic review and Meta-analysis.MethodsA systematic literature search was conducted using PubMed, Embase, Scopus and the web of science Database up to 24 March 2021. Odds ratios were calculated using a random-effects model.ResultsWe identified 66 studies including 39 Asian and 27 non-Asian studies. This study demonstrated that the proportion of hypertension was significantly higher in severe group than in non-severe group for Asian (OR = 2.46) and non-Asian (OR = 1.60, 95% CI: 1.37-1.86, I2 = 84%; p < .00001) patients. Similarly, the proportion of diabetes, cardiovascular disease and chronic kidney disease was significantly higher in severe group than in non-severe group for both Asian and non-Asian studies. We found no statistically significant difference between the severe versus non-severe group for cancer (OR = 1.26) and chronic obstructive pulmonary disease (OR = 1.32) among non-Asian patients.
Project description:Cancer patients are vulnerable to complications of respiratory viruses. This systematic review and meta-analysis sought to examine the prevalence of cancer and its association with disease severity in patients with novel coronavirus disease 2019 (COVID-19). Searches were performed in MEDLINE, EMBASE and ScienceDirect from their inception until 28 April 2020. Severe disease was considered to encompass cases resulting in death or as defined by the primary study authors. Meta-analysis was performed using random-effect models. We included 20 studies involving 32,404 patients from China, the United Kingdom, the United States, Italy, Singapore, Thailand, France, India and South Korea. The pooled prevalence of cancer was 3.50% (95% confidence interval (CI) 1.70 to 5.80). The pooled prevalence was not moderated by study mean age, proportion of females or whether the study was conducted in/outside of China. Patients with cancer were more likely to experience severe COVID-19 disease compared to patients without cancer (pooled risk ratio 1.76, 95% CI 1.39 to 2.23). Our findings reiterate the need for additional precautionary measures to ensure that patients with cancer are not exposed to COVID-19, and if they become infected, extra attention should be provided to minimise their risk of adverse outcomes.
Project description:Early in the COVID-19 pandemic, type 2 diabetes (T2D) was marked as a risk-factor for severe disease. Inflammation is central to the aetiology of both conditions where immune responses influence disease course. Identifying at-risk groups through immuno-inflammatory signatures can direct personalised care and help develop potential targets for precision therapy. This observational study characterised immunophenotypic variation associated with COVID-19 severity in T2D. Broad-spectrum immunophenotyping quantified 15 leukocyte populations in circulation from a cohort of 45 hospitalised COVID-19 patients with and without T2D. Lymphocytopenia, of CD8+ lymphocytes, was associated with severe COVID-19 and intensive care admission in non-diabetic and T2D patients. A morphological anomaly of increased monocyte size and monocytopenia of classical monocytes were specifically associated with severe COVID-19 in patients with T2D requiring intensive care. Over-expression of inflammatory markers reminiscent of the type-1 interferon pathway underlaid the immunophenotype associated with T2D. These changes may contribute to severity of COVID-19 in T2D. These findings show characteristics of severe COVID-19 in T2D as well as provide evidence that type-1 interferons may be actionable targets for future studies.
Project description:ObjectivesThis study aimed to conduct a comprehensive systematic literature review and meta-analysis to assess the risk and outcomes of coronavirus disease 2019 (COVID-19) in patients with rheumatoid arthritis.MethodsA systematic search was performed across four electronic databases. The quality of the studies was assessed using the Newcastle‒Ottawa quality assessment scale and the Joanna Briggs Institute critical appraisal checklist. Statistical analyses were conducted using STATA 14 software.ResultsA total of 62 studies were included in the analysis. First, the meta-analysis revealed the following prevalence rates among rheumatoid arthritis patients: COVID-19, 11%; severe COVID-19, 18%; COVID-19-related hospitalization, 29%; admission to the intensive care unit (ICU) due to COVID-19, 10%; and death from COVID-19, 8%. Second, rheumatoid arthritis was associated with an increased risk of COVID-19 infection (OR 1.045(0.969-1.122), p = 0.006), COVID-19-related hospitalization (OR 1.319(1.055-1.584), p = 0.006), admission to the ICU due to COVID-19 (OR 1.498(1.145-1.850), p = 0.002), and death from COVID-19 (OR 1.377(1.168-1.587), p = 0.001). Third, no statistically significant association was found between rheumatoid arthritis and severe COVID-19 (OR 1.354(1.002-1.706), p = 0.135).ConclusionsRheumatoid arthritis patients have a significantly greater risk of COVID-19 infection, hospitalization, ICU admission, and death than individuals without rheumatoid arthritis. However, rheumatoid arthritis did not show a significant association with the risk of severe COVID-19. These findings underscore the need for tailored management strategies and vigilant monitoring of COVID-19 outcomes in rheumatoid arthritis patients.Systematic review registrationThe study has been registered on PROSPERO [ https://www.crd.york.ac.uk/PROSPERO/ ], and the registration number is CRD42024528119.
