Understanding the Immune Connection in Skin Disorders
Vitiligo and psoriasis are chronic skin conditions with one common thread — they are autoimmune disorders where the immune system mistakenly attacks the body’s own skin cells. Although their symptoms differ, both conditions arise from a dysregulated immune response.
When the immune system becomes overactive, it can damage pigment-producing cells (melanocytes) in vitiligo, or speed up skin cell production in psoriasis. Both result in visible changes to the skin, and in some cases, people can develop both disorders.
Vitiligo vs. Psoriasis – How They Affect the Skin
Vitiligo
Vitiligo causes depigmented patches due to melanocyte destruction. These patches:
- Commonly appear on the face, hands, and genitals, but can occur anywhere.
- May affect hair color in the affected area.
- Can remain stable or spread gradually.
- Sometimes occur symmetrically across the body.
Rarely, vitiligo can also involve inflammation in the eyes or ears.
Psoriasis
Psoriasis results from the immune system accelerating skin cell turnover, leading to:
- Red, pink, or purple rashes (depending on skin tone).
- Thick, scaly patches of skin.
- Itching, burning, and sometimes bleeding skin.
- Nail changes such as pitting or discoloration.
- Psoriatic arthritis in some cases, causing joint pain and swelling.
Psoriasis often fluctuates in severity, with flare-ups triggered by factors like stress, infection, or weather changes.
Having One Condition May Increase Risk of the Other
Research shows:
- People with vitiligo are over three times more likely to develop psoriasis.
- Those with psoriasis are more than twice as likely to develop vitiligo.
- In most cases, patches from both conditions appear in different locations on the body.
Interestingly, psoriasis lesions may leave behind lightened skin after healing, which can resemble vitiligo but is actually hypopigmentation.
Why Do These Conditions Occur Together?
Genetic Factors
- Vitiligo is estimated to be 30% genetic, psoriasis up to 68% genetic.
- Some inflammation-related genes are linked to both disorders.
- Having a family member with one condition may increase the likelihood of developing the other.
Environmental Triggers
- Skin injury (cuts, burns, insect bites) can trigger both conditions — a phenomenon known as the Koebner response.
- Certain medications, such as TNF-alpha inhibitors or biologics for psoriasis, may trigger or worsen vitiligo.
- Infections, including strep throat, Epstein-Barr virus, and COVID-19, have been linked to the onset of these autoimmune disorders.
