OVERVIEW

What is Eczema?

Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by dry, itchy, red, and inflamed skin. It is a common condition that affects people of all ages, but it is most common in infants and children. The exact cause of eczema is not known, but it is thought to be related to a combination of genetic and environmental factors, such as a malfunction in the skin's barrier function, an overactive immune response, and exposure to certain irritants or allergens. Symptoms of eczema can vary from person to person and can include dry, red, and itchy skin, rashes, and blisters. It is a long-term condition that can be managed with a combination of treatments, including moisturizing the skin, avoiding triggers, and taking medication.

CAUSES AND RISK FACTORS 

The exact cause of eczema is not known, but it is thought to be related to a combination of genetic and environmental factors.

• Genetic factors: People with eczema often have a family history of the condition or other atopic diseases such as asthma or hay fever.
• Skin barrier dysfunction: People with eczema have a dysfunction in the skin barrier, which allows moisture to escape and irritants and allergens to enter the skin.
• Immune system dysfunction: Eczema is associated with an overactive immune response, which causes inflammation in the skin.
• Environmental factors: Certain irritants and allergens can trigger eczema symptoms, such as soaps, detergents, lotions, fragrances, and certain fabrics. Also, dry air, low humidity, and cold weather can aggravate eczema symptoms.

Additional risk factors include premature birth, exposure to tobacco smoke, and other atopic conditions such as asthma or hay fever.

It is important to note that not all these factors are necessarily present in every case of eczema, and some cases may have other underlying causes. Consult with a medical professional to help identify the specific cause of your eczema and the best course of treatment.

SIGNS AND SYMPTOMS 

The signs and symptoms of eczema can vary from person to person and can range from mild to severe. Some common symptoms include:

• Dry, itchy skin: This is the most common symptom of eczema, and the itching can be intense and persistent.
• Red, inflamed skin: The skin may appear red and swollen, and there may be small bumps or blisters present.
• Rashes: Eczema can cause a rash to develop on the skin, and the rash may be scaly or crusty.
• Dark-colored patches of skin: Sometimes eczema can cause dark patches of skin, known as hyperpigmentation.
• Cracked or scaly skin: The skin may become thickened or scaly as a result of scratching or rubbing.

Symptoms can appear differently depending on the age of the person, for instance in infants, eczema appears as a red, weepy rash on the face and scalp. In older children and adults, eczema is more likely to appear on the inside of the elbows, behind the knees, and on the hands and feet.

DIAGNOSIS 

The diagnosis of eczema is typically made by a healthcare professional based on the patient's symptoms and a physical examination of the affected skin.

During the physical examination, the healthcare professional will look for the characteristic signs of eczema such as dry, itchy skin, redness, and rashes. They may also take a detailed history of the patient's symptoms, including when the symptoms first appeared, how often they occur, and what seems to make them better or worse.

In some cases, a skin biopsy may be performed to confirm the diagnosis. A skin biopsy involves taking a small sample of skin and analyzing it under a microscope. This can help to rule out other skin conditions that may have similar symptoms.

Blood tests may also be done to rule out other conditions or to check for allergies.

It is important to note that eczema can look similar to other skin conditions such as psoriasis, and a healthcare professional will take the patient's medical history and perform a physical examination to help make a definitive diagnosis. If you suspect you have eczema, it is important to consult with a medical professional for an accurate diagnosis and proper treatment.

MANAGEMENT AND TREATMENT 

The management and treatment of eczema can vary depending on the severity of the condition and the individual's symptoms. The main goal of treatment is to reduce inflammation, relieve itching, and prevent future outbreaks.

The following are some of the most common management and treatment options for eczema:

• Moisturizing the skin: Moisturizing the skin can help to restore the skin's natural barrier and reduce dryness, itching, and redness. It is recommended to use fragrance-free and hypoallergenic moisturizers.
• Avoiding triggers: Identifying and avoiding triggers that cause symptoms to worsen can help to reduce the frequency and severity of outbreaks. Common triggers include certain fabrics, soaps, detergents, and lotions, as well as dry air, low humidity, and cold weather.
• Topical medications: Topical medications such as corticosteroids, calcineurin inhibitors, and topical immunomodulators can be used to reduce inflammation and relieve itching. These medications can be applied directly to the skin in the form of creams, ointments, or lotions.
• Oral medications: Oral medications such as antihistamines can be used to relieve itching and improve sleep. In severe cases, oral corticosteroids may be used for a short period to quickly reduce inflammation.
• Phototherapy: Phototherapy, also known as light therapy, involves exposing the skin to controlled amounts of natural or artificial light. This can help to reduce inflammation and improve skin condition.
• Lifestyle changes: Maintaining a healthy diet, reducing stress, and getting enough sleep can also help to manage eczema symptoms.

It is important to note that each person's eczema is unique and the treatment plan will be tailored to the individual's needs. It is important to consult with a medical professional to help identify the specific symptoms of your eczema and the best course of treatment.

COMPLICATIONS

Eczema can lead to several complications if left untreated or not managed properly. Some of the most common complications include:

• Skin infections: Scratching the itchy skin can cause tiny breaks in the skin, which can allow bacteria or viruses to enter and cause an infection. This is particularly common in people with eczema on their hands.
• Allergic reactions: Eczema can cause allergic reactions to certain substances, such as soaps, detergents, and lotions.
• Scratching and rubbing: Scratching and rubbing the skin can cause further damage to the skin, and lead to thickened or discolored skin.
• Sleep disturbance: Eczema can cause intense itching that can interfere with sleep, leading to daytime fatigue, irritability, and difficulty concentrating.
• Social and emotional issues: Eczema can cause emotional stress, anxiety, and depression. It can also lead to social isolation, as people with eczema may avoid certain activities or situations due to self-consciousness about their skin condition.
• Secondary skin infections: The skin may also get infected with bacteria, viruses, or fungi and may require antibiotics or other treatments.

It is important to work closely with a healthcare professional to manage the symptoms of eczema and prevent complications. With proper treatment, most people with eczema are able to control their symptoms and avoid complications.

PREVENTION

There is no surefire way to prevent eczema, but there are steps that can be taken to reduce the risk of outbreaks and manage symptoms. These include:

• Moisturize the skin: Keeping the skin moisturized can help to restore the skin's natural barrier and reduce dryness, itching, and redness. It is recommended to use fragrance-free and hypoallergenic moisturizers.
• Avoid triggers: Identifying and avoiding triggers that cause symptoms to worsen can help to reduce the frequency and severity of outbreaks. Common triggers include certain fabrics, soaps, detergents, and lotions, as well as dry air, low humidity, and cold weather.
• Keep the skin clean: Use a mild soap or cleanser to wash the skin, and avoid hot water, which can strip the skin of its natural oils. Pat the skin dry after washing, rather than rubbing it.
• Dress in breathable fabrics: Wear loose-fitting, breathable clothing made of natural fibers, such as cotton, to reduce sweating and irritation.
• Keep the skin cool: Avoid overheating, which can cause sweating and itching. Use a fan or air conditioner to keep the room cool, and avoid heavy blankets and bedding.
• Manage stress: Stress can worsen eczema symptoms, so it is important to find ways to manage stress, such as exercise, yoga, meditation, or talk therapy.

Consult a doctor: If you suspect you have eczema, it is important to consult with a medical professional for an accurate diagnosis and proper treatment.

By following these guidelines, most people with eczema are able to reduce the frequency and severity of outbreaks and maintain healthy skin.

PROGNOSIS

The prognosis for eczema varies depending on the severity of the condition and how well it is managed. In general, eczema is a chronic condition that can be managed, but not cured.

Some people with eczema experience periods of remission, where their symptoms disappear for long periods of time, while others experience persistent symptoms. The severity of eczema can also fluctuate over time, with symptoms sometimes worsening or improving.

Proper management of eczema can help to reduce the frequency and severity of outbreaks and improve the overall quality of life. This includes identifying and avoiding triggers, using moisturizers, and taking medications as prescribed.

People with eczema also need to be vigilant about preventing complications such as skin infections, which can occur if the skin is damaged by scratching or rubbing. If a secondary infection is suspected, it should be treated promptly.

In summary, eczema is a chronic condition that can be managed but not cured. With proper management, most people are able to control their symptoms and improve their quality of life.
