Insights

Enfortumab vedotin, an antimitotic therapy, can cause skin reactions like symmetrical drug-related intertriginous and flexural exanthema. Topical corticosteroids effectively treated this adverse event in a patient with urothelial malignancy.

Area of Science:

  • Oncology
  • Dermatology
  • Pharmacology

Background:

  • Urothelial malignancies are often treated with platinum-based chemotherapy.
  • Novel antimitotic therapies, including enfortumab vedotin, are emerging for refractory cases.
  • Enfortumab vedotin targets nectin-4, expressed in various epithelial cancers.

Observation:

  • A patient receiving enfortumab vedotin developed symmetrical drug-related intertriginous and flexural exanthema.
  • This specific cutaneous toxicity is a notable adverse reaction.
  • The patient's condition was successfully managed with topical corticosteroids.

Findings:

  • Enfortumab vedotin, an antibody-drug conjugate, is associated with significant cutaneous toxicity.
  • Symmetrical drug-related intertriginous and flexural exanthema is a documented side effect.
  • Topical corticosteroids provide an effective treatment for this adverse reaction.

Implications:

  • Awareness of potential skin toxicities is crucial for clinicians managing patients on enfortumab vedotin.
  • Prompt recognition and treatment of cutaneous adverse events can improve patient outcomes.
  • Further research into managing side effects of antibody-drug conjugates is warranted.

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Autoimmune Disorders01:29

Autoimmune Disorders

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
