Secundaire Infectie bij Nummulair Eczeem - Oorzaken, Symptomen en Behandeling

Types of Weeping Eczema

There are many types of eczema. Some are prone to blisters and weeping. Weeping eczema may also happen if there is an infection in the skin.

Dyshidrotic Eczema

Dyshidrotic eczema produces tiny, itchy blisters. The rash is usually found on the hands and feet and can last up to a month before clearing.

Dyshidrotic eczema may happen once, occasionally, or be chronic and debilitating.

Nummular Eczema

Nummular eczema usually occurs on the limbs and hands. This type is characterized by tiny bumps and blisters that occur after an injury to the skin, coin-shaped raised spots, and an extremely itchy and dry rash.

Scratching patches of nummular eczema can lead to infections.

Infection

Weeping eczema can also occur with any form of eczema if there is an infection. Most infections with eczema are caused by excessive scratching. The weeping caused by infection is usually pus-colored and accompanied by other signs of infection.

All types of eczema are extremely itchy, which means that scratching is common. However, scratching can lead to infection.

Treatments for Nummular Eczema

Skin Hydration

Dry skin can worsen nummular eczema symptoms or trigger flare-ups. Your dermatologist may recommend applying a hypoallergenic, fragrance-free moisturizing cream or ointment to your skin throughout the day to help trap moisture and promote healing.

Keeping your skin well-hydrated may also involve:

• Bathing or showering daily in lukewarm water
• Adding bath oil to your bathwater
• Using a cool mist humidifier in your bedroom to keep the air moist

Corticosteroids

Corticosteroids are prescription medications that suppress overactive immune responses. As a result, this can reduce inflammation and itchiness. Corticosteroids come in different forms, and the type your healthcare provider prescribes will depend on the severity of nummular eczema. Types of corticosteroids include:

Other Medications

Your healthcare provider may prescribe other topical medications to treat nummular eczema if corticosteroids are ineffective or cause unwanted side effects, such as:

Phototherapy

Phototherapy (light therapy) uses different wavelengths of ultraviolet (UV) light to reduce skin inflammation and soothe symptoms like itching. Healthcare providers may recommend phototherapy for widespread nummular eczema or when topical treatments are ineffective.

During phototherapy treatment, a provider will apply a moisturizing oil to the affected areas of your skin. Your healthcare provider will ask you to wear goggles to protect your eyes from the ultraviolet rays. Most phototherapy sessions only take minutes to complete, though you may need several treatments over one to two months to see improvements.

Antibiotics

People with nummular eczema are prone to developing secondary bacterial infections — most commonly Staphylococcus aureus (staph) infections. S. aureus bacteria naturally live on the skin of 80% of people with eczema. Scratching or rubbing itchy eczema patches can introduce these bacteria deeper into yourthe skin, causing infection.

Causes

The exact cause of eczema is not known. However, some factors can make people more prone to developing eczema, including:

• A personal history of allergies
• A family history of allergies
• Exposure to environmental irritants
• Stress

In addition to being more at risk for eczema in general, there are certain risk factors that may make you more prone to developing a certain type of eczema.

You might be more at risk for dyshidrotic eczema if you:

• Have existing eczema
• Frequently have sweaty or wet hands
• Work with metal or cement

You might be more at risk for nummular eczema if you:

• Are under intense stress
• Are exposed to excessively dry or humid air
• Have a skin injury or skin infection
• Are a heavy user of alcohol

How Skin Damage From Scratching Can Worsen Eczema

Eczema is extremely itchy. People with the condition, especially children, often find it hard not to scratch the rash. However, scratching eczema can cause tiny tears in the skin. These openings allow bacteria, fungus, and viruses to enter and cause an infection.

Scratching an eczema rash damages the skin and can lead to weeping eczema and infections.

When you have eczema, the top layer of your skin is already damaged and there is less protection within the skin. The compromised skin caused by eczema makes people with the condition more prone to skin infections.

Related Conditions

People with nummular eczema, are more likely to have or develop other related conditions, particularly allergic diseases. Research is ongoing, but some evidence suggests that genetic factors and immune dysfunction may play a role in the connection between these conditions and eczema.

When you live with nummular eczema, the relentless itching and discomfort can disrupt your sleep and daily activities. The discomfort can take a toll on your overall well-being. The good news is that proactive skincare practices can reduce the frequency of flare-ups.

Knowing and avoiding your triggers is one of the best ways to reduce flare-ups, but it may take some time before you can identify them. For some people, this may involve wearing cotton clothing and avoiding extreme weather temperatures. For others, avoiding perfumes and personal care products with fragrance and other added chemicals may help.

When flare-ups occur, ask your healthcare provider to work with you to find effective treatments for symptom relief and clearing your skin. Doing so can help you improve symptoms and better your quality of life.

How To Prevent Nummular Eczema

Nummular eczema is a chronic condition that has periods of remission (when symptoms go away with treatment) and flare-ups (when symptoms return). Maintaining a skincare routine that keeps your skin healthy and being aware of possible triggers can help prevent nummular eczema flare-ups. This may include:

• Applying fragrance-free creams, ointments, or body oils daily to keep your skin well-hydrated
• Showering or bathing in lukewarm water and avoiding hot water that dries out your skin
• Using fragrance-free, hypoallergenic, and gentle soaps to cleanse your skin
• Wearing loose-fitting clothing made of breathable factors (e.g., cotton) and avoiding wearing wool or other rough-textured fabrics, such as nylon, spandex, and polyester
• Trying dye-free, fragrance-free laundry detergents
• Visiting your healthcare provider regularly to monitor your skin health and adjust your treatment plan as needed
• Engaging in stress management techniques, such as yoga, meditation, or breathing exercises
• Limiting your alcohol intake
