Ipilimumab is a cytotoxic T-lymphocyte-associated antigen-4-blocking monoclonal antibody, which has shown a significant survival benefit in metastatic melanoma patients. Despite being a promising therapy for a disease with an otherwise rather dismal prognosis, it is associated with several immune-related adverse effects (IRAE) mainly targeted toward the digestive tract, skin, liver, and hypothalamic-pituitary axis. Ipilimumab-induced gastrointestinal toxicity (IGT) include diarrhea (~44 %), colitis (~18 %), bowel perforation (<1 %), and pancreatitis (<1.5 %). Early recognition of IRAE and treatment initiation are critical to decrease the risk of further complications. Management included steroids as initial therapy, followed by infliximab (anti-tumor necrosis factor alpha antibody) and/or surgical option for complications like bowel perforation. We present a series of three patients with metastatic melanoma, who received treatment with ipilimumab, and presented with varying gastrointestinal clinical manifestations and complications. Through this case series, our attempt is to make practicing gastroenterologists cognizant about the wide spectrum of gastrointestinal toxicity of this rather new clinical entity, as well as to discuss management algorithm for IGT.
Lasiodiplodia species are environmental fungi that have been reported as a cause of infection in both immunocompetent and immunocompromised patients. We present a case of fungal osteomyelitis caused by Lasiodiplodia species in a patient with multiple myeloma after autologous stem cell transplant. The patient was successfully treated with a combination of surgery and oral voriconzole. To the best of our knowledge, this is the first reported case of fungal osteomyelitis caused by Lasiodiplodia species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
