Psoriasis Overview
Psoriasis, a chronic skin condition, presents in various forms, most commonly as inflamed plaques. It affects adults mostly, with peaks in specific age groups. Beyond skin, it involves risks like arthritis and heart disease.
Psoriasis shows varied forms and risks, with age-peaked prevalence in adults.
Understanding Psoriasis and Its Variations
Psoriasis is a long-lasting inflammatory skin condition driven by the immune system. It shows up in different forms, the most common being chronic plaque psoriasis, marked by red, swollen patches on the skin covered with silvery scales.
Other forms include guttate psoriasis, often linked to infections and leading to tiny, dot-like lesions, pustular psoriasis with pus-filled lesions, and erythrodermic psoriasis, a rare type that can inflame and scale much of the skin surface.
Psoriasis can affect anyone, though rates differ by region and population.

Source Quotes:
Chronic plaque рѕοriаsiѕ, the most common subtype of рѕоriаѕis, is characterized by well-demarcated, erythematous рlаԛսes with overlying, coarse scale.
Plaque psoriasis is the most common variant, accounting for more than 80% of the psoriasis cases.
Who is Affected by Psoriasis?
Psoriasis can affect anyone, with similar rates in men and women. It's more common in adults, but children can also get it, especially between the ages of 30-39 and 50-69.
In kids, psoriasis often shows up on the face or as guttate psoriasis, which features drop-shaped lesions. The occurrence varies worldwide, with higher rates in some Caucasian and Scandinavian communities than in Asian or African groups.
About 10% of cases start before age 10, with up to a third beginning in childhood.

Its age of onset shows a bimodal distribution with peaks at 30–39 years and 60–69 years in men, and 10 years earlier in women.
Approximately one-third reported onset of disease during the first two decades of life and 10 percent reported onset prior to the age of 10 years.
Beyond the Skin: Psoriasis and Health Risks
Psoriasis affects more than just the skin. It can lead to joint problems like psoriatic arthritis and increase the risk of heart disease and metabolic disorders.
Mental health can also be impacted, with conditions like anxiety and depression being common. These can affect day-to-day activities and overall well-being.

Source Quotes:
Psoriasis patients exhibit increased hyperlipidemia, hypertension, coronary artery disease, type 2 diabetes, and increased body mass index.
Increased rates of various psychopathologies, such as poor self-esteem, sexual dysfunction, anxiety, depression, and suicidal ideation, have been reported in patients with рѕоriаѕis.
Global Prevalence of Psoriasis
Psoriasis affects people worldwide, with 2-11% impacted globally. The rates are higher in Northern Europe and lower in parts of Asia and Africa.
In the U.S., around 3% of adults and less than 1.5% of children are affected. Interestingly, occurrence rates tend to increase the further you move from the equator, which suggests environmental factors might play a role.

The worldwide prevalence is about 2%, but varies according to regions.
A systematic, worldwide review found the prevalence of рѕоriаsiѕ ranged from 0.5 to 11.4 percent in adults and 0 to 1.4 percent in children.
Key Takeaways
Conclusions
Psoriasis is a complex, chronic inflammatory skin condition characterized by distinct subtypes, notably chronic plaque psoriasis with silvery scales.
It affects individuals worldwide, showing demographic and geographic variations, more prevalent in Northern Europe compared to Asia and Africa. A broader understanding reveals psoriasis's systemic connections, including heightened cardiovascular risks and mental health effects.
Addressing these aspects can lead to improved holistic patient outcomes.

Literature Review
Lv, 2018
Comparative Efficacy and Safety:
Anti-IL12/23 and Anti-IL17 efficacy: Both therapies show excellent effectiveness for treating psoriasis.
Adverse effects of therapies: Anti-IL12/23, Anti-IL17, and Anti-TNF-α have a high chance of causing infections.
Recommended Treatment:Anti-IL12/23 is highly recommended due to its efficacy and safety profile compared to Anti-IL17.
Literature Review

cGAS-STING Pathway Role:
Activation of specific cells: Psoriasis involves abnormal activation of skin cells and immune cells.
Pathway signaling in lesions: cGAS-STING signaling increases in psoriatic skin areas.
Therapeutic Insights:The STING inhibitor C-176 reduces psoriatic inflammation and boosts treatment response, suggesting therapy options.
