Insights

Patients with atopic dermatitis (AD) on oral immunosuppressants have an increased risk of non-melanoma skin cancer (NMSC). Older age at therapy start was linked to NMSC development, highlighting the need for careful monitoring.

Area of Science:

  • Dermatology
  • Oncology
  • Pharmacology

Background:

  • Atopic dermatitis (AD) is a chronic inflammatory skin condition.
  • Oral immunosuppressive drugs are used to manage severe AD.
  • The risk of non-melanoma skin cancer (NMSC) in AD patients on these drugs is not well-established.

Purpose of the Study:

  • To investigate the risk of NMSC in patients with atopic dermatitis treated with oral immunosuppressive drugs.
  • To identify risk factors associated with NMSC development in this patient cohort.

Main Methods:

  • Retrospective analysis of 557 patients with AD treated with oral immunosuppressants.
  • Data collected from University Medical Center Utrecht and Groningen, the Netherlands.
  • Comparison of demographic and treatment data between patients who developed NMSC and those who did not.

Main Results:

  • NMSC was observed in 18 patients (3.2%) treated with oral immunosuppressants.
  • A significantly elevated standardized incidence ratio (SIR) of 13.1 for squamous cell carcinoma (SCC) was found.
  • Patients who developed NMSC were older at the start of therapy and at data lock.

Conclusions:

  • Oral immunosuppressive therapy in AD patients is associated with an increased risk of NMSC, particularly SCC.
  • Older age at initiation of immunosuppressive treatment is a risk factor for NMSC development.
  • Further investigation into risk factors and long-term monitoring strategies is warranted.

Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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...

Drug Toxicity: Allergic Reactions

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
