简要总结
Acute Respiratory Distress Syndrome (ARDS) is a life-threatening condition characterized by acute respiratory failure with hypoxemia, noncardiogenic or non-fluid overload pulmonary edema, bilateral diffuse opacities on chest radiograph in the presence of a predisposing factor.
In ARDS there is activation of the inflammatory cascade which is very intense and persistent in the severe types. It was highlighted that the inflammatory cytokines in patients with ARDS or sepsis is similar to that observed in COVID-19 positive patients.
Emerging therapies include immunomodulation and the administration of mesenchymal stem cells for the modulation of lung repair through the release of cytokines and growth factors that modulate the local inflammatory response.
Regardless of the cause of ARDS, the severity of the inflammatory state and fibroproliferative evolution have been shown to be independent predictors of survival and ventilator dependence. Patients suffering from severe forms of ARDS in fact require prolonged mechanical ventilation, which exposes them to ventilator-associated pneumonia (VAP) and the onset of multiorgan insufficiency. The hyperinflammatory state underlying ARDS predisposes to pulmonary fibroproliferation, which in turn increases susceptibility to ventilator dependence and increases the risk of MOF and death. For this reason, the rationale in the use of anakinra is to limit the inflammatory process of ARDS as early as possible, avoiding the progression of lung damage.

anakinra 100 mg/day for 14 consecutive days
干预措施: Anakinra 100Mg/0.67Ml Inj Syringe (Drug)
结局指标
主要结局
Assessment of ventilation-free days
时间窗: 28 days
The calculation will take place from the day of extubation to the 28th day of hospitalization. Patients who die before ventilator weaning will be considered as having 0 days off ventilation. The calculation of the days free from ventilation will be calculated as follows: 28 - number of days of ventilation.
