Nivolumab and interferon-γ rescue therapy to control mixed mould and bacterial superinfection after necrotizing fasciitis and septic shock.

Immunosuppression is a major feature of septic shock and patients are at increased risk for opportunistic infections. We describe a successful use of immunostimulation to treat mixed mould and bacterial superinfection in a previously healthy 38-year-old female patient admitted for severe extensive fasciitis. Interferon gamma associated with nivolumab reversed successfully deactivation of immune cells assessed by altered expressions of monocyte human leukocyte antigen-DR (HLA-DR) and lymphocyte programmed death receptor-1 (PD-1). Immunosuppressed patients in ICU with invasive bacterial and fungal infections may benefit from immunostimulation.

Acute aortoiliac occlusion in a patient with novel coronavirus disease-2019.

The severe acute respiratory syndrome novel coronavirus-2 pandemic is affecting almost every country in the world. Even if the major symptoms of coronavirus disease-2019 are respiratory, different symptoms at presentation are now recognized. Venous thromboembolism has been reported in infected patients and few but increasing cases of arterial thrombosis have been described. We report a case of acute aortoiliac and lower limb artery occlusions in a patient presenting with severe coronavirus disease-2019 infection. The mechanism of the occlusion seemed to be distal embolization from a floating thrombus in the aortic arch caused by a major inflammatory state and virus infection. The patient underwent aortoiliac and lower limb artery mechanical thrombectomy, but required unilateral major amputation.
