Concomitant Human Herpes Virus 6 and nivolumab-related pneumonitis: Potential pathogenetic insights
نویسندگان
چکیده
The development of immune system modulating agents, such as immune checkpoint inhibitors (ICIs), has revolutionized cancer treatment. Nivolumab, a human monoclonal antibody against PD-1, has emerged as an efficient treatment for various malignancies, including non-small cell lung cancer (NSCLC); however, it is associated with important immune related side-effects, attributed to organ-specific inflammation, such as immune-mediated pneumonitis, a relatively uncommon, albeit potentially fatal adverse event. We herein present the unique case of severe interstitial pneumonitis with concomitant detection of Human Herpes Virus 6 (HHV-6) in a nivolumab treated patient with NSCLC. Potential pathogenetic mechanisms are discussed.

Association between mycosis fungoides and human herpes virus 8: A case-control study
Background: Mycosis fungoides is the most common type of primary cutaneous T-cell lymphoma. Its etiopathogenesis, despite numerous studies, remains unclear. Environmental, viral, and genetic factors have been proposed as its potential etiologic factors. In recent years, viral agents of herpes virus family such as human herpes virus 8 (HHV-8) have been noticed.Objective: The aim of this study wa...
متن کاملHerpes simplex virus bronchiolitis in a cannabis user.
Herpes simplex virus (HSV) lower respiratory tract infections in adults are uncommon. We present a case of HSV bronchiolitis and pneumonitis in an immunocompetent individual, likely linked to chronic habitual marijuana use and a herpetic orolabial ulcer. The case serves as a reminder to consider HSV as a potential unusual cause of lower respiratory tract infection/inflammation in individuals wi...

BACKGROUND Nivolumab, an anti-programmed cell death-1 (PD-1) monoclonal antibody used as an immune checkpoint inhibitor, is commonly employed for its anti-tumor effects against various types of malignant tumors. However, its administration is complicated by immune-related adverse events (irAEs), including pneumonitis. CASE PRESENTATION We present a case series of four patients with malignant ...

Nivolumab is a recently approved medication for the treatment of unresectable malignant melanoma. Many immune-related adverse events (irAEs) associated with nivolumab have been reported, such as pneumonitis, hepatitis, dermatitis, and thyroiditis. Prednisolone can effectively treat irAEs. However, it is unclear how or if nivolumab should be administered to patients after they have experienced a...

PURPOSE We conducted a meta-analysis of published clinical trials to determine the relationship between the risks of pneumonitis and pneumonitis-related death and programmed cell death-1 (PD-1) inhibitor treatment in patients with cancer. MATERIALS AND METHODS We examined clinical trials from the Medline and Google Scholar databases. Data from original studies and review articles were also cr...
