T2 | 74-82 | Sentence | denotes | Abstract |
T3 | 83-93 | Sentence | denotes | Background |
T4 | 94-149 | Sentence | denotes | Evidence links COVID-19 severity to hyper-inflammation. |
T5 | 150-327 | Sentence | denotes | Treatment with tocilizumab, a monoclonal antibody directed against the interleukin-6 (IL-6) receptor, was shown to lead to clinical improvement in patients with severe COVID-19. |
T6 | 328-537 | Sentence | denotes | We, therefore, performed the present systematic review and meta-analysis to investigate whether the circulating levels of IL-6 is a reliable indicator of disease severity among patients affected with COVID-19. |
T7 | 539-546 | Sentence | denotes | Methods |
T8 | 547-653 | Sentence | denotes | A systematic search was conducted in PubMed, Scopus, Web of Science, and Google Scholar on April 19, 2020. |
T9 | 655-662 | Sentence | denotes | Results |
T10 | 663-818 | Sentence | denotes | Eleven studies provided data of IL-6 levels in patients with severe to critical COVID-19 (severe) and patients with mild to moderate COVID-19 (non-severe). |
T11 | 819-873 | Sentence | denotes | The included studies were of moderate to high quality. |
T12 | 874-1035 | Sentence | denotes | The mean patients’ age was 60.9 years, ranging from 45.2 to 76.7 years in the severe group and 46.8 years, ranging from 37.9 to 61 years, in the nonsevere group. |
T13 | 1036-1128 | Sentence | denotes | Fifty-two percent were male in the severe group, as compared to 46% in the non-severe group. |
T14 | 1129-1313 | Sentence | denotes | An overall random effects meta-analysis showed significantly higher serum levels of IL-6 in the severe group than in the non-severe group with a mean difference of +23.1 pg/mL (95% CI: |
T15 | 1314-1376 | Sentence | denotes | 12.42–33.79) and the overall effect of 4.24 (P-value < 0.001). |
T16 | 1377-1498 | Sentence | denotes | Meta-regressions showed that neither age nor sex significantly influenced the mean difference of IL-6 between the groups. |
T17 | 1500-1511 | Sentence | denotes | Conclusions |
T18 | 1512-1640 | Sentence | denotes | Meta-analysis and meta-regression reveal a reliable relationship between IL-6 and COVID-19 severity, independent of age and sex. |
T19 | 1641-1767 | Sentence | denotes | Future research is, however, required to assess the effect of BMI on the pattern of IL-6 production in patients with COVID-19. |
T20 | 1768-1902 | Sentence | denotes | Also, there might be confounding factors that influence the relationship between IL-6 and COVID-19 severity and remain as yet unknown. |
