| Abstract | A 59-year-old treatment-naive patient with advanced HIV infection presented with a severe and protracted course of mpox (formerly known as monkeypox) that did not respond to the current mpox treatment options. The patient worsened clinically, and developed new mucocutaneous lesions and necrotic evolution of pre-existing ones, along with multiple bilateral lung nodules and the appearance of a tracheal necrotic lesion. Although severe forms of mpox have been observed in people with severe immune system deficiency, including those with advanced HIV presentation, the immunological mechanisms underlying this observation have not yet been fully explained. To our knowledge, this is the first account of a necrotising mpox in a person living with HIV, with viral shedding for more than 11 months and a comprehensive immunological description. Moreover, we documented the virus' persistence by detecting mpox virus DNA from multiple sites and quantified anti-monkeypox virus IgA, IgM, IgG, and neutralising antibodies in serum samples. The severe HIV-driven immune depression and the presence of other co-infections might skew and impair immune responses, thus contributing to the persistence of monkeypox virus infection. Further investigations of immune responses to monkeypox virus infection in people with severe immunosuppression are required to improve management and prevention. |
