Psoriasis

Definition

Psoriasis is a chronic, inflammatory skin condition characterized by the rapid buildup of skin cells, resulting in scaly, red patches on the body. It is an autoimmune disorder that affects the body's normal skin cell growth and turnover process, leading to the development of these distinctive lesions.

5 Must Know Facts For Your Next Test

1. Psoriasis is not contagious and cannot be passed from person to person through physical contact.
2. Stress is a well-known trigger for psoriasis flare-ups, as it can weaken the immune system and exacerbate the condition.
3. Certain medications, such as beta-blockers, lithium, and antimalarial drugs, have been associated with the development or worsening of psoriasis in some individuals.
4. Psoriasis is often a lifelong condition, with periods of remission and flare-ups, and can significantly impact a person's quality of life.
5. Treatments for psoriasis aim to stop the rapid growth of skin cells, reduce inflammation, and remove scales, with options ranging from topical creams to systemic medications and phototherapy.

Review Questions

• Explain the connection between psoriasis and the immune system.
  • Psoriasis is an autoimmune disorder, meaning that the body's immune system mistakenly attacks its own healthy skin cells, leading to the rapid buildup of skin cells and the development of the characteristic red, scaly patches. This abnormal immune response is a key driver of the inflammation and skin cell overgrowth seen in psoriasis, highlighting the important role the immune system plays in the development and progression of this chronic condition.
• Describe how stress can impact the symptoms and management of psoriasis.
  • Stress is a well-established trigger for psoriasis flare-ups. When an individual experiences high levels of stress, it can weaken the immune system and lead to increased inflammation, which in turn can exacerbate the skin lesions and symptoms of psoriasis. Effective stress management, through techniques such as relaxation exercises, mindfulness practices, or counseling, can help individuals with psoriasis better control their condition and prevent or minimize flare-ups.
• Evaluate the potential impact of certain medications on the development and progression of psoriasis.
  • Some medications, such as beta-blockers, lithium, and antimalarial drugs, have been associated with the onset or worsening of psoriasis in some individuals. These medications may trigger or exacerbate the abnormal immune response and skin cell growth that characterize psoriasis. Individuals with psoriasis should be aware of this potential link and discuss any medication changes with their healthcare provider, as adjustments to their treatment plan may be necessary to manage both their primary condition and the psoriasis effectively.
