Eczema, also known as atopic dermatitis, is a common, chronic, inflammatory skin condition characterized by regions of skin that are red, irritating, and dry. It affects individuals of all ages, but neonates and children are most commonly affected. Eczema is not contagious, but its precise cause remains unknown.
Atopic dermatitis is one of several forms of eczema and is frequently used interchangeably with the term “eczema.” It is the most common and severe variant, afflicting 10 to 20 percent of children and 1 to 3 percent of adults globally. In recent decades, the prevalence of atopic dermatitis has increased, particularly in industrialized nations, due to various environmental and lifestyle factors.
1.Variants of Eczema
There are several distinct varieties of eczema, each with its own triggers and characteristics. Among the most prevalent varieties are:
- Atopic dermatitis: The most prevalent form of eczema, atopic dermatitis is characterized by irritating, inflamed, and dehydrated skin. It is frequently linked to a family history of atopic disorders, such as asthma and hay fever.
- Contact dermatitis: This form of eczema develops when the skin comes into contact with an allergen or irritant, causing an allergic reaction or direct irritation. Soaps, detergents, cosmetics, and specific metals are frequent allergens. (e.g., nickel).
- Dyshidrotic eczema: This form of eczema affects the hands and feet, causing small, fluid-filled lesions that can become irritating and uncomfortable.
- Nummular eczema:This type of eczema, also known as discoid eczema, is characterized by coin-shaped regions of irritated skin, which typically appear on the arms and legs.
- Seborrheic dermatitis:This form of eczema typically affects the cranium, face, and upper body, resulting in red, scaly regions of skin. In neonates, it is sometimes referred to as “cradle cap.”
2. Reasons and Threat Factors of Eczema
Eczema is believed to be caused by a combination of genetic and environmental factors, although the exact cause is not entirely understood. Among the primary contributors to the development of dermatitis are:
- Genetic predisposition: Those with a family history of eczema or other atopic conditions (e.g., asthma, hay fever) are more likely to develop the condition.
- Immune system dysfunction: An overactive immune system may cause inflammation and eczema symptoms by responding excessively to certain stimuli or antigens.
- Skin barrier dysfunction: A compromised skin barrier allows moisture to escape and irritants or pollutants to enter, thereby contributing to the development of eczema.
- Environmental factors: Exposure to allergens (e.g., pollen, canine dander), irritants (e.g., cleansers, detergents), temperature fluctuations, and humidity levels can provoke or aggravate eczema symptoms.
- Stress: High levels of tension can impair the immune system, making the epidermis more prone to eczema outbreaks.
3. Indications and symptoms of Eczema
Symptoms of eczema can vary between individuals and evolve over time. Common symptoms and indications of eczema include:
- Red, inflamed epidermis
- Extreme burning
- Scaly, dry skin
- Small, fluid-filled sores (vesicles)
- Ruptured and thickened epidermis
- Skin discoloration (e.g., hyperpigmentation or hypopigmentation)
- inflammation and heat in afflicted regions
Symptoms of eczema typically follow a pattern of flare-ups and remissions, with periods of increased severity followed by periods of improvement or total resolution.
4. Diagnosis and Evaluation of Eczema
A comprehensive medical history, a physical examination of the skin, and an evaluation of potential triggers and risk factors are typically required to diagnose dermatitis. There is no specific test for the diagnosis of eczema, but a healthcare provider may execute the following to rule out other conditions and assess the severity of the condition:
- Allergy testing: Patch testing, skin probe tests, or blood tests can help identify potential allergens that may be contributing to the development of eczema symptoms.
- Skin biopsy: In some instances, a small skin sample may be removed and examined under a microscope to rule out the possibility of other skin conditions.
- Severity assessment: Healthcare providers may use the Eczema Area and Severity Index (EASI) or Scoring Atopic Dermatitis (SCORAD) to assess the severity of eczema and track treatment progress.
It is essential to consult a healthcare professional in order to obtain an accurate diagnosis and individualized treatment plan.
5. Management and Treatment
There is no remedy for eczema, but various remedies and management strategies can help alleviate symptoms, reduce the frequency and severity of flare-ups, and enhance the quality of life for those afflicted. Options for treatment include:
5.1 Topical Therapy of Eczema
The first line of defense in the management of eczema symptoms is frequently topical remedies, which are administered directly to the skin. These are common topical treatments:
- Moisturizers: Regular use of fragrance-free, hypoallergenic moisturizers assists in maintaining the skin’s barrier function, reducing dehydration, and relieving irritation.
- Topical corticosteroids: These medications help reduce inflammation and irritation when applied topically. The appropriate efficacy depends on the severity of the condition and the area of the epidermis that is afflicted.
- Topical calcineurin inhibitors: Non-steroidal calcineurin inhibitors, such as tacrolimus and pimecrolimus, are frequently used as an alternative to corticosteroids for long-term management or in sensitive areas. (e.g., face, neck).
- Topical PDE4 inhibitors: Crisaborole, a topical phosphodiesterase-4 (PDE4) inhibitor, can reduce inflammation and irritation in mild to moderate dermatitis.
5.2 Systemic Procedures of Eczema
Generally, systemic therapies are reserved for severe instances of eczema that do not respond to topical treatments. The following are examples of systemic treatments:
- Oral corticosteroids: These medications, such as prednisone, can provide rapid relief of severe eczema symptoms, but long-term use is generally discouraged due to the risk of adverse effects.
- Immunosuppressants: Medications such as cyclosporine, methotrexate, and mycophenolate mofetil suppress the overactivity of the immune system and reduce inflammation.
- Biologic therapy: Dupilumab, a monoclonal antibody that provides relief for moderate to severe atopic dermatitis by inhibiting specific proteins implicated in the inflammatory process, is a form of biologic therapy.
Phototherapy, also known as light therapy, is the controlled exposure of the epidermis to ultraviolet (UV) radiation to reduce inflammation and irritation. Individuals who do not respond favorably to topical or systemic treatments may benefit from this treatment option.
5.4 Way of Life and Home Remedy
In addition to medical treatments, a number of lifestyle adjustments and domestic remedies can aid in the management of eczema symptoms:
- Avoid triggers: Identify and avoid allergens and irritants that may contribute to eczema outbreaks. (e.g., certain soaps, detergents, fabrics).
- Maintain a healthy skin barrier: Maintain a healthy skin barrier by bathing in tepid water and applying an emollient within a few minutes of bathing to seal in hydration.
- Use humidifiers: Keep indoor humidity levels between 40-60% to prevent excessive skin fatigue.
Choose apparel manufactured from natural fibers, such as cotton, to reduce skin irritation.
Utilize stress-reduction techniques, such as meditation, yoga, or deep breathing exercises, to manage tension.
6. Complications and Related Disorders
Eczema can result in a variety of complications and is frequently accompanied by other atopic conditions. Among the possible complications and associated conditions are:
- Infections of the skin: Scratching or tearing the skin can introduce bacteria, resulting in infections that may require antibiotic therapy.
- Sleep disturbances: Intense irritation can disrupt sleep, resulting in fatigue and diminished quality of life.
- Mental health issues: Living with a chronic skin condition such as dermatitis can contribute to feelings of anxiety, melancholy, and alienation.
- Asthma and hay fever: Individuals with eczema are more likely to develop asthma and hay fever, two other atopic conditions. (allergic rhinitis).
7. Eczema in Infants and Children
Symptoms of eczema frequently manifest in neonates and children before the age of five. In the majority of cases, eczema symptoms improve as a child ages; however, some individuals may continue to experience symptoms into maturity. Developing an appropriate treatment and management plan for children with dermatitis requires consultation with a healthcare professional, as their skin is more delicate and may require specialized care.
Treatment and management strategies for infants and children with eczema are comparable to those for adults, but may need to be modified to accommodate the child’s age, skin sensitivity, and specific requirements. Among the factors to consider when treating eczema in neonates and children are:
- Gentle skincare: Utilize soothing, fragrance-free cleansers and moisturizers formulated specifically for infants and children. Avoid abrasive cleansers and froth baths, as they can deplete the skin of its natural lipids and exacerbate eczema symptoms.
- Avoiding triggers:Identify and minimize exposure to allergens (e.g., pet dander, dust mites), irritants (e.g., synthetic fabrics, abrasive garments), and environmental triggers. (e.g., temperature changes, low humidity).
- Prevention of clawing: Keep the child’s nails brief and tidy to reduce skin injury caused by scratching. Consider wearing soft cotton mitts or mittens, particularly while sleeping, to prevent involuntary clawing.
- Wet wraps: For moderate to severe eczema, healthcare personnel may recommend wet wrap therapy, which consists of applying a moist layer of garments or bandages over topical medications to enhance their efficacy and provide additional relief.
As the child ages, it is crucial to involve them in their eczema care by educating them about their condition and assisting them in developing healthy practices for managing their symptoms. Encourage open communication and offer emotional support to assist children in coping with any feelings of humiliation or self-consciousness associated with their eczema.
