Durvalumab-associated vasculitis presenting as ‘the blue toe syndrome’

Abstract: Durvalumab is a selective, high-affinity human immunoglobulin monoclonal antibody in a class called check point inhibitors, that blocks PD-L1 on tumour cells. Despite clinical success in increasing progression-free survival rates in patients with stage III non-small-cell lung cancer, durvalumab has been associated with immune-related side effects such as pneumonitis and colitis. We present a case of an 84-year-old woman with acral vasculitis presenting as blue toe syndrome, associated with prolonged use of dur… Show more

“…Several irAEs of special interest have been described in elderly patients treated with PD1/PD-L1 axis inhibitors and are summarized in Table 2. They included severe cutaneous adverse reactions [135][136][137][138][139][140], secondary sclerosing cholangitis [141], colangiopathy [142,143], immune-related hepatitis [144,145], type 1 diabetes [146][147][148], hypophysitis [149], primary adrenal insufficiency [150], myasthenia gravis and myopathy [151][152][153][154], myocarditis [154][155][156][157], severe heart failure [158], eosinophilic vasculitis and arteritic anterior ischemic optic neuropathy [159], blue toe syndrome due to peripheral vasculitis [160], Vogt-Koyanagi-Harada Disease-like Uveitis [161], acute interstitial nephritis [134,162], fulminant Goodpasture's disease [163], neuromyelitis optica [164], isolated optic neuritis [165], encephalitis [166], hypereosinophilia [167], severe neutropenia [144,[168][169][170], immune thrombocytopenia [171], autoimmune hemolytic anemia and hemophagocytic lymphohist...…”

“…Durvalumab-associated acral vasculitis has previously been reported. 5 Cardiovascular irAEs other than AVEs include those that primarily affect the heart, such as myocarditis, cardiomyopathy, heart failure, and heart block. Though cardiovascular irAEs are overall rare, they can quickly cause severe morbidity and mortality, often due to arrhythmia or shock.…”

“…Serologies rarely are positive, and the diagnosis is lack of autoantibodies in vasculitis. In a recently case with NSCLC, the patient developed acral vasculitis after receiving anti-PD-L1 mAb therapy ( 62 ). The laboratory test results revealed a positive perinuclear-ANCA, and negative anti-myeloperoxidase (MPO) and anti-proteinase 3 (PR3) antibodies.…”
