Immune checkpoint inhibitors (ICIs), such as anti-programmed cell-death 1/programmed death-ligand 1 (anti-PD-1/PD-L1) or anti-CTL-associated protein (anti-CTLA-4), have dramatically changed the treatment of advanced cancers over the past decade. ICIs block T cell inhibition, thus increasing the anti-tumor immune response. ICIs are used not only for metastatic cancer, but also as adjuvant treatment for some stage…
NEW YORK (Reuters Health)—Patients with preexisting autoimmune disease (AIDs) are not at increased risk for immune-related adverse events from immune checkpoint inhibitor (ICI) therapy, although these adverse events may be more likely in patients with inflammatory bowel disease (IBD), new research indicates. “Therefore, we encourage physicians not to withhold ICI in most common AIDs. However,…
Immune checkpoint inhibitors effectively treat malignancy in ways that were not possible just a few years ago, but immune-related adverse events are a potential side effect.
Immune checkpoint inhibitors (ICIs) are at the forefront of advances in cancer therapy and have shown promising results for progression-free survival. Checkpoint signaling pathways, such as cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed cell death protein 1 (PD-1), normally regulate the immune response to promote self-tolerance and prevent tissue damage and inflammation. PD-1 is a…
Since they were first introduced in 2011, immune checkpoint inhibitors (ICIs) have become an important treatment for an expanding list of advanced cancers. Some concerns have been raised around the mechanism of action of these immunotherapy agents, making their use in rheumatic diseases (RD) problematical. An article in the March 2018 issue of Arthritis &…
A 53-year-old female presented to the clinic for severe polyarticular joint pain and was found to have a seronegative inflammatory arthritis. Six months before, she had completed 10 months of treatment for stage IV metastatic melanoma with the immune checkpoint inhibitors, nivolumab and ipilimumab, achieving complete remission of her cancer. She said that throughout her…
NEW YORK (Reuters Health)—After an immune-related adverse event, the risk-reward ratio for an anti-PD-1 (anti-programmed death-1) or anti-PD-L1 (anti-programmed death ligand-1) rechallenge seems to be acceptable if patients are closely monitored, researchers say. “The immune checkpoint inhibitors anti-PD-1 and anti-PD-L1 have proven efficacy in the treatment of many cancers, but patients may experience immune-related adverse…
Introduction: Major advances in the past two decades have enhanced our understanding of the complex interactions between the immune system and cancer cells and their environment. Genetic and epigenetic alterations in tumor cells result in the expression of diverse antigens that can elicit an immune response, primarily mediated by T cells. Immune responses are regulated…
Ultrasound may provide unique insights into the effects of immune checkpoint inhibitors on the human body beyond the immune system. Research suggests synovitis and inflammatory tendon involvement are commonly seen in patients with immune checkpoint inhibitor-induced inflammatory arthritis.
Recent research found inflammatory arthritis caused by immune checkpoint inhibitors (ICIs) may become a long-term disease, requiring rheumatology care and immunomodulatory treatment. Some patients experience active inflammatory arthritis years after ICI cessation…
