This study aims to evaluate if tocilizumab, an anti-soluble IL-6 receptor monoclonal antibody, reduces patients' mortality.\nMethods: 85 consecutive patients admitted to the Montichiari Hospital (Italy) with COVID-19 related pneumonia and respiratory failure, not needing mechanical ventilation, were included if satisfying at least one among: respiratory rate ≥ 30 breaths/min, peripheral capillary oxygen saturation ≤ 93% or PaO2/FiO2\u003c=300 mmHg. Patients admitted before March 13th (n=23) were prescribed the standard therapy (hydroxychloroquine, lopinavir and ritonavir) and were considered controls. On March 13th tocilizumab was available and patients admitted thereafter (n=62) received tocilizumab once within 4 days from admission, plus the standard care.\nResults: Patients receiving tocilizumab showed significantly greater survival rate as compared to control patients (hazard ratio for death, 0.035; 95% confidence interval [CI], 0.004 to 0.347; p = 0.004), adjusting for baseline clinical characteristics. Two out of 62 patients of the tocilizumab group and 11 out of 23 in the control group died. 92% and 42.1% of the discharged patients in the tocilizumab and control group respectively, recovered. The respiratory function resulted improved in 64.8% of the observations in tocilizumab patients who were still hospitalized, whereas 100% of controls worsened and needed mechanical ventilation. No infections were reported.\nConclusions: Tocilizumab results to have a positive impact if used early during Covid-19 pneumonia with severe respiratory syndrome in terms of increased survival and favorable clinical course.","tracks":[{"project":"LitCovid-OGER-BB","denotations":[{"id":"T1","span":{"begin":19,"end":30},"obj":"DG_35"},{"id":"T2","span":{"begin":66,"end":74},"obj":"SP_7"},{"id":"T3","span":{"begin":106,"end":115},"obj":"UBERON:0002048"},{"id":"T4","span":{"begin":121,"end":132},"obj":"UBERON:0001004"},{"id":"T5","span":{"begin":170,"end":175},"obj":"GO:0016265"},{"id":"T6","span":{"begin":179,"end":187},"obj":"SP_7"},{"id":"T7","span":{"begin":241,"end":245},"obj":"UBERON:0002048"},{"id":"T8","span":{"begin":285,"end":296},"obj":"DG_35"},{"id":"T9","span":{"begin":314,"end":318},"obj":"PR:000001393"},{"id":"T10","span":{"begin":339,"end":347},"obj":"GO:0042571"},{"id":"T11","span":{"begin":461,"end":469},"obj":"SP_7"},{"id":"T12","span":{"begin":492,"end":503},"obj":"UBERON:0001004"},{"id":"T13","span":{"begin":597,"end":608},"obj":"UBERON:0001004"},{"id":"T14","span":{"begin":643,"end":652},"obj":"UBERON:0001982"},{"id":"T15","span":{"begin":782,"end":800},"obj":"CHEBI:5801;DG_20;CHEBI:5801"},{"id":"T16","span":{"begin":802,"end":811},"obj":"CHEBI:31781;DG_23;CHEBI:31781"},{"id":"T17","span":{"begin":816,"end":825},"obj":"CHEBI:45409;DG_30;CHEBI:45409"},{"id":"T18","span":{"begin":871,"end":882},"obj":"DG_35"},{"id":"T19","span":{"begin":946,"end":957},"obj":"DG_35"},{"id":"T20","span":{"begin":1045,"end":1056},"obj":"DG_35"},{"id":"T21","span":{"begin":1150,"end":1155},"obj":"GO:0016265"},{"id":"T22","span":{"begin":1301,"end":1312},"obj":"DG_35"},{"id":"T23","span":{"begin":1357,"end":1361},"obj":"GO:0016265"},{"id":"T24","span":{"begin":1411,"end":1422},"obj":"DG_35"},{"id":"T25","span":{"begin":1470,"end":1481},"obj":"UBERON:0001004"},{"id":"T26","span":{"begin":1541,"end":1552},"obj":"DG_35"},{"id":"T27","span":{"begin":1702,"end":1713},"obj":"DG_35"},{"id":"T28","span":{"begin":1769,"end":1777},"obj":"SP_7"},{"id":"T29","span":{"begin":1800,"end":1811},"obj":"UBERON:0001004"}],"namespaces":[{"prefix":"NCBITaxon","uri":"https://www.ncbi.nlm.nih.gov/taxonomy/"}],"attributes":[{"subj":"T1","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T2","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T3","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T4","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T5","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T6","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T7","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T8","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T9","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T10","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T11","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T12","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T13","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T14","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T15","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T16","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T17","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T18","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T19","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T20","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T21","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T22","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T23","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T24","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T25","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T26","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T27","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T28","pred":"source","obj":"LitCovid-OGER-BB"},{"subj":"T29","pred":"source","obj":"LitCovid-OGER-BB"}]},{"project":"hydroxychloroquine","denotations":[{"id":"T1","span":{"begin":83,"end":92},"obj":"Phenotype"},{"id":"T2","span":{"begin":106,"end":115},"obj":"Phenotype"},{"id":"T3","span":{"begin":121,"end":140},"obj":"Phenotype"},{"id":"T4","span":{"begin":478,"end":487},"obj":"Phenotype"},{"id":"T5","span":{"begin":492,"end":511},"obj":"Phenotype"},{"id":"T6","span":{"begin":1778,"end":1787},"obj":"Phenotype"}],"attributes":[{"id":"A1","pred":"hp_id","subj":"T1","obj":"http://purl.obolibrary.org/obo/HP_0002090"},{"id":"A6","pred":"hp_id","subj":"T6","obj":"http://purl.obolibrary.org/obo/HP_0002090"},{"id":"A3","pred":"hp_id","subj":"T3","obj":"http://purl.obolibrary.org/obo/HP_0002878"},{"id":"A4","pred":"hp_id","subj":"T4","obj":"http://purl.obolibrary.org/obo/HP_0002090"},{"id":"A2","pred":"hp_id","subj":"T2","obj":"http://purl.obolibrary.org/obo/HP_0002090"},{"id":"A5","pred":"hp_id","subj":"T5","obj":"http://purl.obolibrary.org/obo/HP_0002878"},{"subj":"T1","pred":"source","obj":"hydroxychloroquine"},{"subj":"T2","pred":"source","obj":"hydroxychloroquine"},{"subj":"T3","pred":"source","obj":"hydroxychloroquine"},{"subj":"T4","pred":"source","obj":"hydroxychloroquine"},{"subj":"T5","pred":"source","obj":"hydroxychloroquine"},{"subj":"T6","pred":"source","obj":"hydroxychloroquine"}]},{"project":"Inflammaging","denotations":[{"id":"T1","span":
