Highlights
Hyperinflammation in COVID-19 activates blood coagulation increasing thrombotic risk.
Tocilizumab blocks IL-6 receptor and may improve inflammatory-induced hypercoagulability.
Tocilizumab was associated with rapid and sustained coagulation improvement.
These benefits were consistent independently of thromboprophylaxis dose.
Highlights
Early treatment with low-dose tocilizumab TCZ (324 mg, administered subcutaneously in two simultaneous 162 mg injections) was used to prevent progression of disease in a subgroup of patients with moderate COVID-19 pneumonia and hyperinflammation.
Low-dose subcutaneous tocilizumab TCZ (324 mg) was well-tolerated with no significant adverse effects.
Low-dose subcutaneous tocilizumab TCZ (324 mg) was associated with a rapid and significant reduction in C reactive protein (CRP) paralleled by a progressive improvement in oxygenation as reflected by the ratio of partial pressure of oxygen to fraction of inspired oxygen (P/F) ratio.
None of the TCZ-treated patients had disease progression, suggesting that IL-6 receptor blockade with subcutaneous TCZ may prevent COVID-19 progression when administered early in the course of disease.
Background: In the treatment of idiopathic pulmonary fibrosis (IPF), nintedanib and pirfenidone, with their different mechanisms of action, lead to a reduction in the rate of progression of the fibrosis process measured by the reduction of functional decline, and, in particular, the decrease in forced vital capacity (FVC) and of the diffusion capacity of the lungs for carbon monoxide (DLCO). The objective of this study was to analyze real-life adherence, persistence and efficacy in the use of pirfenidone and nintedanib in the treatment of IPF. Methods: A non-interventional multicenter retrospective observational pharmacological study in real-life treat-ment at 1 and 2 years was conducted. Furthermore, we analyzed the levels of FVC and DLCO at 6 and 12 months, respectively, from the start of treatment. Results: We identified 144 patients in the period between January 2013 and April 2019. From the point of view of adherence, there is no difference between the two drugs, even though patients who used pirfenidone had increasingly higher values: 0.90 vs 0.89, in the first year, and 0.91 vs 0.84, in the second year. In the first year of treatment, the percentage of persistent patients was 67% and 76%, while in the second year, it dropped to 47% and 53% for pirfenidone and nintedanib, respectively. Conclusion: The stratification of the adherence values as a function of the response to treatment in terms of FVC at 12 months for both study drugs showed that patients with optimal response scored adherence of more than 90%.
High-flow nasal cannula (HFNC) has often been used in the treatment of acute respiratory failure during pulmonary rehabilitation setting. The aim of this retrospective study was to investigate the utility of HCFN during the early rehabilitation in COVID-19 pneumonia. Twenty-two patients (10 males and 12 females, mean age 64.5 ± 5.9 years) with COVID-19 pneumonia were considered. Medical data and rehabilitative scales were used to evaluate acute hypoxemic respiratory failure (PaO2/FiO2 < 300), treated with HFNC three times during evaluation. Overall clinical outcomes from the evaluation of the synergy between HFNC strategy and rehabilitation were evaluated. A statistically significant improvement was observed at T2 (and of treatment) in 1 minute sit to stand test (1STST) (4 ± 3 vs. 17 ± 5, p < 0.05), short physical performance battery (SPPB) (4.3 ± 2.81 vs. 9.15 ± 2.39, p < 0.05), SpO2% post effort (93 ± 1.26 vs. 98 ± 1.01, p < 0.05), respiratory rate post effort (RR) (24 ± 3.91 vs. 20 ± 3.13, p < 0.05), heart rate (HR) (97 ± 11.9 vs. 87 ± 9.17, p < 0.05), P/F rate (235 ± 7.35 vs. 331 ± 10.91, p < 0.05), SpO2 (86 ± 4.54 vs. 97 ± 1.01 p < 0.05), RR (20 ± 4 vs. 12 ± 1.39, p < 0.05). Then, treated HFNC patients showed a good improvement in physical performance at T2 and a good compliance with treatments proved to be extremely useful in the control and reduction of dyspnea and fatigue symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
