Vitiligo: Causes, Symptoms, Diagnosis, and Treatment

Vitiligo: Causes, Symptoms, Diagnosis, and Treatment

Vitiligo is a chronic skin disease affecting many people worldwide, characterized by the formation of white patches on the skin. This condition occurs due to the loss of function or destruction of skin cells called melanocytes, resulting in the skin's inability to produce pigment. Vitiligo is a common dermatological condition that can lead to changes in skin color and socially stressful situations. In this article prepared for you, you will learn about vitiligo and explore who develops the disease, its types, and treatment methods.

What is Vitiligo?

Vitiligo is a pigmentation disorder characterized by well-defined white patches on the skin. This disease develops due to the reduction or disappearance of cells called melanocytes, which determine the skin's color. Vitiligo can develop at any age and in any skin type, but typically begins before age 20. Although the exact cause of vitiligo remains unknown, it is believed that genetic factors, autoimmune diseases, and environmental factors play a role in the disease's development.

Who Develops Vitiligo?

Vitiligo can occur in all age groups and skin types, but generally begins before age 20 and has certain risk factors. Individuals with a family history of vitiligo have a higher risk of developing the disease. Additionally, those with autoimmune conditions (such as thyroid diseases, lupus, and type 1 diabetes) or those whose skin is repeatedly exposed to trauma such as friction or sunburn may also be at higher risk of developing vitiligo.

What Are the Types of Vitiligo?

Vitiligo is generally divided into two main types: segmental vitiligo and non-segmental vitiligo.

Segmental vitiligo: This type of vitiligo appears on one side of the body or in a specific area and typically begins rapidly. Segmental vitiligo is more common in children and adolescents and is less commonly seen than other types of vitiligo.

Non-segmental vitiligo: This type of vitiligo is characterized by white patches appearing symmetrically on both sides of the body. Non-segmental vitiligo typically begins on the hands, feet, face, and skin folds and may spread over time. This type of vitiligo is commonly seen among patients.

Various subtypes of vitiligo also exist and can be classified according to the spread of the disease and affected areas. These include localized vitiligo, generalized vitiligo, and universal vitiligo. Since each patient's vitiligo condition is different, it is important to work with dermatologists for proper diagnosis and treatment.

What Causes Vitiligo?

Vitiligo is a skin disease characterized by white patches on the skin, resulting from the loss of function or destruction of cells called melanocytes. Melanocytes are cells that produce melanin, the color pigment of the skin. Melanin is a pigment that determines skin color and protects against ultraviolet radiation. Although the exact cause of vitiligo is unknown, it is believed that several factors contribute to its development.

• Vitiligo has been observed to have a familial predisposition. Individuals with a family history of vitiligo have a higher risk of developing the disease.

• There are theories suggesting that vitiligo develops as a result of the immune system attacking and destroying melanocytes. This condition is considered an autoimmune disease.

• Neuronal Theory. According to this theory, vitiligo develops as a result of nerve damage to melanocyte cells.

• Increased free radicals in the body and weakened antioxidant defense systems resulting in melanocyte damage may contribute to vitiligo development.

• Environmental factors such as chemical exposure, sunburn, skin trauma, and stress can also be effective in the development of vitiligo.

What Are the Symptoms of Vitiligo?

Vitiligo manifests with white patches on the skin, its most distinctive characteristic. These patches can appear on any part of the body and may grow over time. The symptoms of vitiligo are as follows:

• White Patches on the Skin

• Changes in Hair Color

• Changes in Eye and Ear Color

• Skin Itching

Symptoms of vitiligo vary from person to person, and the progression rate of the disease may also differ. Individuals suspected of having vitiligo should be evaluated by a dermatologist.

How is Vitiligo Diagnosed?

Vitiligo is typically diagnosed through the patient's complaints, physical examination, and certain laboratory tests. Here are the details on how vitiligo is diagnosed:

Vitiligo diagnosis typically begins with the patient's complaints about white patches on the skin and the doctor's examination of these patches. The patches are usually located symmetrically on both sides of the body and frequently appear in areas such as the hands, face, knees, and ankles.

Another method used in vitiligo diagnosis is Wood's lamp examination. This is a special ultraviolet lamp that makes vitiligo patches more apparent. Under the Wood's lamp, vitiligo patches appear brighter and whiter than normal skin.

In some cases, skin biopsy may be necessary for vitiligo diagnosis. During this procedure, the doctor takes a small tissue sample from the skin and sends it to the laboratory for examination under a microscope. If the biopsy results show that melanocyte cells are reduced or absent, a diagnosis of vitiligo can be made.

Vitiligo may in some cases be associated with autoimmune diseases such as thyroid disease, diabetes, and pernicious anemia. For this reason, doctors may order blood tests to check for the presence of these diseases.

Rarely, imaging tests may be used for vitiligo diagnosis. Particularly if the patient has concerns about the thyroid gland, tests such as ultrasound or radioactive iodine scan may be performed.

How is Vitiligo Treated?

Vitiligo treatment varies depending on the patient's age, type of vitiligo, size and extent of patches, and should be planned by a physician. The main goal of treatment is to help stop pigment loss from the skin and support the return of the skin's natural color, though results can vary from person to person. Some methods used in vitiligo treatment are as follows:

• In vitiligo treatment, topical corticosteroids, calcineurin inhibitors, and creams or ointments such as vitamin D analogs can be used initially. These medications aim to help stop pigment loss on the skin and support the skin's return to its natural color.

• Phototherapy is a treatment method that uses ultraviolet (UV) light to stimulate pigment production in the skin. The most commonly used type of phototherapy in vitiligo treatment is narrowband UVB (NB-UVB) therapy. PUVA (psoralen and UVA) therapy can also be used, but is less commonly preferred.

• Microskin grafting is a procedure in which small tissue samples taken from the patient's normally pigmented skin are transplanted to vitiligo patches. This method may be considered for patients who have not responded to other treatments; outcomes can vary and should be discussed with a physician.

• Skin Color Matching Treatments. These treatments aim to reduce skin color differences by lightening the normally pigmented skin surrounding vitiligo patches. These methods include applications such as cryotherapy (cold therapy), laser therapy, and chemical peeling.

• Cosmetic products can be used to cover vitiligo patches and even out skin color. Products suitable for skin type, including waterproof options, may be considered in consultation with a healthcare provider.

• Vitiligo can affect patients' self-confidence and quality of life. Therefore, psychological support may be included in vitiligo treatment. Psychotherapy, group therapy, and stress management techniques can help patients cope with emotional difficulties they experience.

Vitiligo Treatment Costs in Turkey

Turkey has made investments in the healthcare field, including the use of technological equipment in diagnostic and treatment procedures. There has also been an increase in medical tourism to Turkey.

Some factors that patients and their relatives may consider when evaluating healthcare options include:

• Hospital infrastructure and equipment

• The experience of healthcare professionals

• Communication and support provided by healthcare staff

• Response time to questions and requests

• Support provided by intermediary companies assisting patients
