Psoriasis: Understanding its Types, Causes, Symptoms, and Impact on Quality of Life

Psoriasis is a chronic skin condition with a prevalence of approximately 2% worldwide. It is not only confined to the skin and nails but may also affect joints (psoriatic arthritis) and eyes (uveitis)[1,2]. Despite being a common condition, psoriasis has no definite cure. In this article, we will discuss different types of psoriasis, causes of the disease, symptoms it presents, treatment options available, and its impact on quality of life.

Types of Psoriasis

Plaque Psoriasis: This is the most common form of psoriasis, characterized by raised, red patches covered with white or silver scales. It can appear anywhere on the body but usually occurs on knees, elbows, scalp, and lower back.
Pustular Psoriasis: In this type, small blisters containing pus develop on affected areas in response to physical stressors like infection or injury. Pustular psoriasis can occur in localized forms (e.g., palmoplantar, generalized, guttate).
Erythrodermic Psoriasis: This rare but severe form causes widespread, fiery redness and scaling over much of the body. Patients may feel intense itching and burning pain throughout their bodies.
Scalp Psoriasis: Scaly plaques are present on the scalp, which may lead to hair loss or thinning.
Nail Psoriasis: The nails become thickened, separated from the nail bed, and sometimes show pitting or surface indentation.
Inverse or Interdigital Psoriasis: This form affects areas where skin rubs together such as the underarms, groin area, buttocks, and armpits.
Guttate Psoriasis: This occurs when small red spots appear on the trunk, arms, and legs, often triggered by strep infection.

Causes of Psoriasis

The exact cause of psoriasis remains unknown, but several factors are thought to contribute to its development. These include genetic susceptibility, environmental factors, stress, trauma to the skin, and certain medications.

Symptoms of Psoriasis

The most frequent symptoms experienced by patients with psoriasis include scaling (94%), itching (79%) and skin redness (71%). Additionally, some people may develop pustules, and others can have joint pain related to psoriatic arthritis. The severity of symptoms varies among individuals.

Treatments for Psoriasis

There is no cure for psoriasis, so treatment focuses on managing symptoms and preventing flares. Common treatments include topical creams and ointments, light therapy, oral and injectable drugs, and systemic immunosuppressants. Biologics have also shown significant improvement in patients' quality of life, despite their added cost and side effects.

Impact of Psoriasis on Quality of Life

Psoriasis has a profound impact on a patient's quality of life. It is associated with social stigma, mental health problems like depression and anxiety, physical disability, and economic burden. A study found that at least 20% of psoriasis patients had contemplated suicide. Furthermore, psoriasis can affect workplace performance due to physical and emotional effects.

In conclusion, understanding psoriasis' types, causes, symptoms, and impact on quality of life is crucial for both healthcare providers and patients. With proper treatment and management strategies, many people with psoriasis can improve their overall well-being and live fulfilling lives.
