Severe Late-Onset Drug-Induced Immune Thrombocytopenia Following IFN -1a Treatment: A Case Report of a 52-Year-Old Woman with Relapse-Remitting Multiple Sclerosis. | LitMetric
Interferon -1a (IFN1a) is considered safe in relapsing-remitting multiple sclerosis (RRMS). Drug-induced thrombocytopenia (DITP) is a rare but underreported adverse event that is often confused with other causes of thrombocytopenia. We report the case of a 52-year-old woman who developed limb and oral mucosa petechiae and hematochezia, 10 years after beginning IFN1a. Blood work showed an isolated severe thrombocytopenia and ruled out other autoimmune diseases, viral infections, intravascular hemolysis, and renal impairment. Oral corticosteroids and tranexamic acid were initiated with a favorable platelet response. IFN1a was resumed, leading to recurrence of thrombocytopenia. Platelets came back to normal after intravenous immunoglobulins and IFN1a was definitively discontinued. To our knowledge, this is the first case of drug-induced immune thrombocytopenia (DITP) associated with IFN1a.
Immune checkpoint inhibitor (ICI) therapies have made considerable advances in cancer immunotherapy, but the complex and diverse spectrum of ICI-induced toxicities poses substantial challenges to treatment outcomes and computational analysis. Here we introduce DySPred, a dynamic graph convolutional network-based deep learning framework, to map and predict the toxicity profiles of ICIs at the population level by leveraging large-scale real-world pharmacovigilance data. DySPred accurately predicts toxicity risks across diverse demographic cohorts and cancer types, demonstrating resilience in small-sample scenarios and revealing toxicity trends over time.
Sweet syndrome (SS), originally described as acute febrile neutrophilic dermatosis, is a rare inflammatory skin condition, considered the prototype of neutrophilic dermatoses. It is characterised by the sudden onset of well-defined tender papules, plaques and nodules often accompanied by fever, neutrophilia and elevated markers of inflammation. Several variants have been described both clinically and histopathologically.
Ceftriaxone, a widely used antibiotic, is one of the most common drugs to cause drug-induced immune hemolytic anemia. In this report, we describe the effect of ceftriaxone on red blood cell parameters (low red blood cell count, low hematocrit, and high erythrocyte index values) in two pediatric patients without clinical symptoms of hemolytic anemia. Although automated hematology analyzers have helped to detect incorrect results, a peripheral blood smear examination was necessary for recognizing the erythrocyte agglutinins caused by ceftriaxone.
Background: Immune checkpoint inhibitors (ICIs) play a central role in cancer immunotherapy. However, the occurrence of immune-related adverse events, especially ICI-induced interstitial lung disease (ICI-ILD), is life-threatening and affects the effectiveness of ICI treatment. This study aimed to explore potential drugs to mitigate ICI-ILD occurrence using data from the Japanese Adverse Drug Event Report (JADER) and the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS [JAPIC AERS]).
Vaccines are the most effective tool against COVID-19 and are generally safe. Very rare and heterogeneous cases of acute liver injury associated to all types of SARS-CoV-2 vaccines have been reported, mostly with autoimmune features. Epidemiological studies used heterogeneous diagnostic criteria and included different populations.
