Diffuse pneumonitis from coronavirus HKU1 on checkpoint inhibitor therapy.

ABSTRACT: BACKGROUND:Immune checkpoint inhibitors (ICIs) can produce specific immune-related adverse events including pneumonitis. The impact of ICI therapy on the severity of acute coronavirus infection symptomatology warrants further exploration. CASE PRESENTATION:We report a 65-year-old man diagnosed with stage IV melanoma who developed pulmonary and brain metastases and was treated with bilateral craniotomies followed by combined nivolumab and ipilimumab immunotherapy. He developed early-onset severe dyspnea associated with acute coronavirus HKU1 (non-COVID-19) infection, with diffuse pneumonitis evidenced by ground glass opacification on CT scan. He was treated with steroids leading to resolution of pneumonitis on repeat imaging, suggesting an exacerbated immune-mediated toxicity. CONCLUSION:We report the first case of a patient with melanoma with severe and reversible diffuse pneumonitis in association with coronavirus HKU1 following combined nivolumab and ipilimumab immunotherapy. Although we do not have data on the impact of ICI therapy on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) symptomatology, a possible interaction should be considered when deciding on dosing in patients with possible SARS-CoV-2 exposure or when evaluating patients with presumed ICI-related pneumonitis during the COVID-19 pandemic.
