Dermatitis atópica: cómo los fibroblastos están cambiando la vida de las personas

Atopic dermatitis, also known as atopic eczema, is a chronic skin disease characterized by dryness, inflammation, and itching. It is one of the most common forms of dermatitis and usually begins in childhood, although it can appear at any age.

Those who suffer from this disease know that its symptoms can become extremely uncomfortable and that conventional treatments often involve the use of corticosteroids or antihistamines with negative side effects. For this reason, today at Fcells we will talk a little more about this topic and how autologous fibroblast treatment can be a good option to improve dermal inflammation from its roots.

Atopic dermatitis: symptoms that are not easy to eliminate

Although atopic dermatitis is not a life-threatening problem for those who suffer from it, when it is moderate to severe, it can indeed represent a significant obstacle to a person's quality of life, especially because it is a recurring condition and often unpredictable in its reappearance.

It is not just the physical discomfort caused by the constant itching; this can also lead to sleep disturbances, poor self-esteem due to aesthetic impairments, intensification of stress and depression, limitation of recreational activities such as exercise—since sweat exacerbates the symptoms—a high economic cost due to the treatments needed to keep symptoms under control, and even affect social and family relationships.

Its main symptoms are as follows:

• Reddened and inflamed skin that occasionally presents small, fluid-filled blisters that can ooze and form crusts.

• Intense itching, so much so that even though scratching causes pain, the patient continues to do so.

• Skin rashes that can appear anywhere on the body, most commonly on the hands, feet, ankles, wrists, face, neck, and upper chest.

• Dry, rough, thickened, and scaly skin in dermatitis lesions that do not heal. There may also be a change in coloration in the surrounding skin, becoming either lighter or darker.

• Skin infections, since affected skin areas are more susceptible to bacteria, viruses, and fungi.

• Some people with atopic dermatitis may also present ocular symptoms, such as watery or itchy eyes.

The severity and duration of symptoms can vary widely between individuals. Some people only have small areas of dry skin and occasional itching, while others may experience extensive rashes and intense itching for long periods.

What factors contribute to the development of atopic dermatitis?

The exact cause of the disease is unknown, but it is believed to be the result of a complex interaction of genetic, immunological, or environmental factors related to the skin barrier.

Family history: atopic dermatitis tends to be more common in families where members have eczema, asthma, or hay fever, as well as food allergies. Certain genes have been identified that are associated with a greater susceptibility to the disease.

Alterations in the skin barrier: people with atopic dermatitis often have deficiencies in certain skin proteins, which can make it more susceptible to irritants and allergens. This compromised skin barrier can also allow for greater water loss and, therefore, make it more prone to extreme dryness.

Abnormal immune response: the immune system overreacts to certain allergens or irritants, leading to skin inflammation.

Environmental and emotional factors: such as dry or cold climates, sweating, stress, exposure to chemical or physical irritants like soaps, detergents, wool, or dust; allergens such as pollen, dust mites, mold, or certain foods.

Hormonal factors: in some women, symptoms of atopic dermatitis may worsen during certain times of the menstrual cycle or during pregnancy.

How do fibroblasts relate to skin health and function?

Fibroblasts are essential cells for skin health and function. They play a crucial role in the structure and repair of cutaneous tissue and are mainly responsible for the production of collagen and elastin in the dermis. Collagen provides strength and structure to the skin, while elastin provides elasticity.

Their key role in wound repair and healing, the production of the extracellular matrix that provides support, nutrition, and water retention for skin cells, and their participation in defense against external agents through the mediation of the immune response, mean that any alteration in fibroblasts has serious consequences for skin health.

In aesthetic and regenerative medicine, autologous fibroblasts (obtained from the patient themselves) are being used for innovative skin treatments. By reintroducing active fibroblasts into the skin, the goal is to stimulate the production of collagen and elastin, improving appearance and resistance.

How can fibroblasts help treat or improve the symptoms of atopic dermatitis?

Although research on fibroblasts for atopic dermatitis is very recent, their role in skin regeneration and health suggests that reintroducing healthy fibroblasts into the tissue could have a positive impact on improving the symptoms of affected skin.

• Restoring the skin barrier, facilitating water retention, and preventing the entry of allergens and pathogens.

• Stimulating collagen production, improving the texture and appearance of the skin.

• Acting as a fundamental and active part of the immune response by interacting with other types of skin barrier cells and the immune system through the secretion of growth factors and cytokines.

• Accelerating the tissue healing and repair process.

Furthermore, fibroblast therapy could complement other conventional treatments for atopic dermatitis, enhancing their effects and offering a more comprehensive improvement of the skin.

Consult your doctor to see if your skin is a candidate for autologous fibroblast treatment, and discover how reintroducing health and youth to your skin improves your quality of life.
