Obesity represents a higher risk of severe COVID-19 infection, which may lead to the requirement of a mechanical ventilation in intensive care units and premature death. The underlying mechanisms are multiple: alteration of the respiratory performance, presence of comorbidities such as diabetes, hypertension or obstructive sleep apnea, finally inadequate and excessive immunological responses, possibly aggravated by ectopic intrathoracic fat depots. Thus, COVID-19 may challenge the so-called « obesity paradox » commonly reported by intensivists in patients with acute respiratory distress syndrome. These findings require reinforced preventive and curative measures among obese patients to limit the risk of progression towards an unfavorable outcome in case of COVID-19.

Review[Venous thrombotic risk related to SARS-CoV-2 : prevalence, recommendations and perspectives].
Since the SARS-CoV-2 pandemic outbreak, growing evidence suggests that patients suffering from COVID-19 are at increased risk of thrombotic events. The sepsis-related activation of the coagulation combined with a high prevalence of common thrombotic risk factors could contribute to this prothrombotic state. ⋯ Based on that knowledge, several societies have provided recommendation on the prevention of venous thromboembolism. In this narrative review, we summarize available epidemiologic data on venous thromboembolism and recommendations on thromboprophylaxis in COVID-19.
