Vitiligo is a chronic (long-lasting) autoimmune disorder that causes patches of skin to lose pigment or color. This happens when melanocytes – skin cells that make pigment – are attacked and destroyed, causing the skin to turn a milky-white color.
Vitiligo is an autoimmune disease of the skin, which means that someone with vitiligo has an immune system that is malfunctioning in a small way. The normal role of the immune system is to protect you from infections and cancer.
Vitiligo occurs when immune cells destroy the cells that make brown pigment (melanocytes). This destruction is thought to be due to an autoimmune problem. An autoimmune disorder occurs when the body's immune system, which normally protects the body from infection, attacks and destroys healthy body tissue instead.
The disease does not affect life expectancy. However, it can have a significant impact on quality of life, especially psychologically and be responsible for disorders such as depression and anxiety.
Vitiligo is a common pigmentary disorder caused by the destruction of functional melanocytes. Vitamin D is an essential hormone synthesized in the skin and is responsible for skin pigmentation. Low levels of vitamin D have been observed in vitiligo patients and in patients with other autoimmune diseases.
Vitiligo is caused by the lack of a pigment called melanin in the skin. Melanin is produced by skin cells called melanocytes, and it gives your skin its colour. In vitiligo, there are not enough working melanocytes to produce enough melanin in your skin. This causes white patches to develop on your skin or hair.
Studies suggest that vitamin D3 increases tyrosinase activity and melanogenesis in vitro [12], which may lead to repigmentation in vitiligo skin lesions. Calcipotriol and tacalcitol, which are vitamin D analogs, are also known to induce repigmentation in patients with vitiligo [13,14].
Research suggests that most people who develop vitiligo do so during childhood. As you age, Dr. Mohta says untreated vitiligo often progresses to involve the surrounding skin or create new patches of discoloration.
Vitiligo — like many skin conditions — can be challenging to live with, mainly because of the way the skin looks. However, people with vitiligo are usually in good health and live normal lives. If it is not associated with symptoms that cause physical discomfort or complications, the condition may be left untreated.
The condition usually begins with small white patches in a localized area. If the vitiligo progresses it can gradually spread across the body over time.
About 15 to 25 percent of people with vitiligo are also affected by at least one other autoimmune disorder, particularly autoimmune thyroid disease, rheumatoid arthritis, type 1 diabetes, psoriasis , pernicious anemia, Addison disease, systemic lupus erythematosus, celiac disease, Crohn disease, or ulcerative colitis.
As non-segmental vitiligo is closely associated with other autoimmune conditions, you may be assessed to see whether you have any symptoms that could suggest an autoimmune condition, such as: being tired and lacking energy (signs of Addison's disease) being thirsty and needing to urinate often (signs of diabetes)
Many people who have vitiligo are often otherwise healthy. Even so, it's important to find a doctor like a dermatologist who knows about vitiligo. People who have vitiligo have a higher risk of getting some other medical conditions. You can also get painful sunburns on the skin that has lost color.
Vitiligo is a chronic (long-lasting) autoimmune disorder that causes patches of skin to lose pigment or color. This happens when melanocytes – skin cells that make pigment – are attacked and destroyed, causing the skin to turn a milky-white color.
Who gets vitiligo? People of all races and skin colors can get vitiligo, and the disease occurs about equally in people of all races. About half the people who develop vitiligo get it before they turn 20 years of age. For many of these people, vitiligo begins when they're a child.
Complications of vitiligo are social stigmatization and mental stress, eye involvement like iritis, depigmented skin is more prone to sunburn, skin cancer, and hearing loss because of loss of cochlear melanocytes. Other complications are related to medications like skin atrophy after prolonged use of topical steroids.
Moreover, people with vitiligo lack melanin, which is the body's natural protection from the sun, so sun exposure can be particularly dangerous. That's why it's vital that people with vitiligo use broad-spectrum sun protection with an SPF (sun protection factor) of 30 and above.
It is also true that the lack of pigment in the skin in vitiligo patients, which results from the loss of the pigment-producing cells called melanocytes, makes them more likely to burn when spending time in the sun.
Significant number of vitiligo patients have diverse psychological problems. Hormonal response to psychological stress such as cortisol has a role in the development of vitiligo.
Vitiligo signs include: Patchy loss of skin color, which usually first appears on the hands, face, and areas around body openings and the genitals.
Some people lose color in areas called mucous membranes, which includes the inside of the mouth or nose and the genitals. Vitiligo can also affect the hair, causing white or prematurely gray hair.
Vitamin C is not used and is contraindicated in treating vitiligo as it disrupts the melanin production pathways [21]. Vitamin D is a fat-soluble vitamin that absorbs substances like calcium and magnesium.
Vitamin B12 has been shown to be useful for repigmentation in patients suffering from vitiligo. Folic acid (or vitamin B9) has been proven to be significant for treating vitiligo.
Skin lesions associated with vitamin B12 deficiency are skin hyperpigmentation, vitiligo, angular stomatitis, and hair changes. Cutaneous lesions that do not respond to conventional therapy can be an indication of vitamin B12 deficiency.
