Dyshidrotic Eczema

Dyshidrotic eczema, also known as pompholyx, is a type of skin condition that causes small, itchy blisters to form on your hands and feet. Imagine getting tiny, intensely itchy water balloons on your skin. The exact cause of dyshidrotic eczema is still a mystery to doctors. However, it is often linked to seasonal allergies or stress, and it seems to be more common in people who have a history of other types of eczema. It’s kind of like a pesky uninvited guest that shows up when you’re already dealing with a lot.

Types of Dyshidrotic Eczema

Dyshidrotic eczema typically falls into two categories based on how long it lasts.

1. Acute Dyshidrotic Eczema: This form of eczema tends to appear suddenly. It typically presents with many small, intensely itchy blisters. The symptoms may last for a few weeks and then disappear. Most people with dyshidrotic eczema experience acute bouts.
2. Chronic Dyshidrotic Eczema: Unlike the acute form, chronic dyshidrotic eczema is persistent. The blisters may be less in number, but the itchiness can be extreme. The skin might become thick and cracked due to consistent scratching. The problem persists for many months or even years, and the symptoms can be more severe.

Causes

1. Allergies: Allergies can trigger dyshidrotic eczema. If you’re allergic to certain substances, like nickel or fragrances, it can cause these pesky blisters.
2. Stress: High-stress levels can cause your body to react in unusual ways, including causing dyshidrotic eczema outbreaks.
3. Sweating: Sweating a lot? This could be a trigger. When sweat is trapped under your skin, it can lead to this form of eczema.
4. Hot and humid weather: Heat and humidity can cause you to sweat more, which in turn, can trigger dyshidrotic eczema.
5. Cold and dry weather: On the flip side, cold, dry climates can also lead to dyshidrotic eczema by drying out the skin.
6. Contact with irritants: Chemicals in detergents, soaps, and cleaning supplies can cause skin irritation, leading to dyshidrotic eczema.
7. Fungal infections: Yeast and other fungal infections can trigger this skin condition.
8. Bacterial infections: Similarly, bacterial infections can also cause dyshidrotic eczema.
9. UV light exposure: Too much exposure to ultraviolet (UV) light from the sun can trigger this condition.

30. Endocrine disorders: Conditions that affect your hormones, like thyroid problems, can trigger dyshidrotic eczema.

Symptoms

Dyshidrotic eczema, also known as pompholyx, primarily affects your palms, sides of the fingers, and soles of the feet. It can be bothersome and painful, but understanding the signs can help you seek timely treatment. So, let’s dive right into these symptoms.

1. Small Fluid-filled Blisters: One of the first symptoms are small blisters filled with fluid, often appearing on the sides of the fingers, palms, or soles. These blisters can be as small as a pinhead or larger.
2. Itching: An itch is often the first sign. This itch may intensify once blisters start forming, and it’s usually worse before the blisters appear.
3. Pain: If these blisters burst or become inflamed, they can cause significant pain. This discomfort is often sharp and localized to where the blisters are.
4. Redness: Affected skin areas may become red, signalling inflammation. This is your body’s response to the condition.
5. Sweating in Affected Areas: People with this condition may notice an increase in sweating where they have blisters.
6. Swelling: As with many skin conditions, swelling or puffiness is a common symptom due to inflammation and fluid build-up.
7. Scaly Skin: Over time, the skin in affected areas may become scaly or rough, which is a result of chronic irritation and scratching.
8. Cracked Skin: Dry, cracked skin often occurs in the aftermath of the blisters, especially if you’ve been scratching.
9. Changes in Skin Color: Long-term dyshidrotic eczema can cause skin discoloration, typically making it darker.
10. Thickened Skin: Chronic cases often result in thicker skin on the hands or feet, a result of the body’s response to continual inflammation.
11. Burning Sensation: Some individuals may feel a burning sensation, typically in tandem with itching and pain.
12. Fluid Leakage: When the blisters burst, clear or yellowish fluid may leak out, which can be bothersome.
13. Bacterial Infection Signs: Signs of secondary bacterial infection, like pus or increased pain, can occur if open sores are not kept clean.
14. Nail Changes: The condition may cause changes to your nails, such as pitting (small dents) or discoloration.
15. Peeling Skin: Skin may start to peel, particularly as blisters dry up or following intense itching episodes.
16. Difficulty in Moving Fingers or Toes: Severe swelling and pain can hinder the free movement of fingers or toes.
17. Increased Symptoms under Stress: Many patients report flare-ups during periods of stress.
18. Worsening in Warm Weather: Symptoms often worsen in hot, humid weather.
19. Frequent Skin Infections: Frequent skin infections may indicate dyshidrotic eczema, especially if you have other symptoms.
20. Flare-ups After Contact with Irritants: If symptoms flare up after contact with potential irritants like nickel, cobalt, or certain cosmetic products, it could be a sign.

Diagnosis

Tests and diagnoses for dyshidrotic eczema.

1. Medical History Review: This is where doctors begin. They ask questions about your symptoms, previous medical issues, and family history of skin problems.
2. Visual Inspection: Doctors can often diagnose dyshidrotic eczema by just looking at the skin. The tiny blisters are usually a tell-tale sign.
3. Patch Testing: This is a method used to identify if you’re allergic to something that could be causing your eczema. Doctors apply small patches with different substances to your skin and check for reactions.
4. KOH Test: This test checks for fungal infections, which can look like dyshidrotic eczema. A solution with potassium hydroxide (KOH) is applied to a skin sample, which dissolves skin cells and leaves behind any fungi.
5. Allergy Blood Test: This test checks for specific antibodies in the blood. If you have higher levels, you might be allergic to certain substances, which can trigger eczema.
6. Skin Biopsy: In rare cases, doctors might take a small sample of your skin to examine under a microscope. This helps rule out other skin conditions.
7. Prick Test: A tiny amount of a potential allergen is put on your skin using a small needle. If your skin reacts, you could be allergic to that substance.
8. Intradermal Test: A small amount of allergen is injected under your skin. A stronger response than the prick test might indicate an allergy.
9. Atopy Patch Test: It’s similar to a patch test, but it’s used to identify airborne allergens like dust mites or pollen.
10. Tzanck Test: A test used to check for herpes virus, which can sometimes look like eczema.
11. Swab Test: A simple test where a cotton swab is rubbed on the skin to collect samples for bacterial or viral infections.
12. Phototesting: This test uses light to diagnose different skin conditions and to determine your skin’s sensitivity to UV light.
13. IgE Test: This blood test checks for levels of IgE antibodies, which are often higher in people with allergies or asthma.
14. Asthma Test: Many people with eczema also have asthma. Pulmonary function tests, like spirometry, can identify asthma.
15. Complete Blood Count (CBC): While not specific to eczema, this test can give an overall picture of your health and can highlight inflammation or infection.
16. Eosinophil Count: This test counts eosinophils, a type of white blood cell often elevated in people with allergies or skin conditions like eczema.
17. C-Reactive Protein Test: This blood test checks for inflammation in the body, which can be higher in people with eczema.
18. Dermoscopy: This non-invasive method uses a magnifying tool to visualize details of the skin not visible to the naked eye.
19. Skin Scraping: A doctor scrapes a small part of your skin to check for conditions that might be confused with dyshidrotic eczema, like psoriasis.
20. RAST Test: The Radioallergosorbent test is an older form of blood test for allergies. It has largely been replaced by newer methods, but some doctors may still use it.
21. Food Allergy Test: Eczema can be worsened by food allergies. These tests can identify potential culprits.
22. ESR Test: The erythrocyte sedimentation rate test checks for inflammation in the body, which can indicate the severity of eczema.
23. Immunofluorescence: This technique uses fluorescent dyes to visualize specific proteins in skin samples, helping to diagnose certain skin diseases.
24. Lymphocyte Count: This test counts the number of lymphocytes, a type of white blood cell. These cells may increase with skin issues like eczema.
25. Trypsin Test: High trypsin levels can indicate inflammation or damage to the skin.
26. Erythroderma Test: This test is used to identify severe skin diseases that can occur with untreated eczema.
27. Histamine Test: Histamine is a substance that your body makes during an allergic reaction. This test can help identify potential allergens.
28. Protein Electrophoresis: A blood test used to measure specific proteins in the blood and detect any abnormalities.
29. Serum Protein Test: This blood test measures the amount of proteins in your blood. Certain protein levels can be higher with skin diseases like eczema.
30. Contact Hypersensitivity Test: This test checks how your skin reacts to certain substances to identify if any cause allergic reactions.

Treatment

Don’t worry; we’ve got you covered with the top treatments for this condition. Let’s dive in!

1. Moisturizing creams: These are your first line of defense. They help hydrate the skin, reducing dryness and itching.

2. Steroid creams or ointments: When moisturizers aren’t enough, doctors often recommend corticosteroid creams. They work by reducing inflammation and can help clear up your eczema faster.

3. Over-the-counter hydrocortisone creams: These are weaker forms of steroids that you can buy without a prescription. They can help with mild eczema.

4. Oral corticosteroids: For severe cases, your doctor might give you corticosteroids in pill form. They can quickly control the symptoms, but shouldn’t be used long-term due to side effects.

5. Coal tar preparations: Sounds strange, right? But this old-school remedy can help slow skin cell growth and ease symptoms.

6. Anti-itch creams or lotions (containing pramoxine): These can help control itching, a common symptom of dyshidrotic eczema.

8. Anti-fungal creams: These are helpful if your eczema is triggered by a fungal infection.

9. UV light therapy: Also known as phototherapy, this treatment uses UV light to reduce inflammation and improve symptoms.

10. Patch testing: This is more of a diagnostic procedure, but it can help figure out if allergies are causing your eczema, so you can avoid those triggers.

11. Botulinum toxin injections: In severe cases, injections of Botox might be used to control excessive sweating that can worsen eczema.

12. Immunosuppressant drugs: Drugs like methotrexate or cyclosporine may be prescribed for severe or chronic cases that don’t respond to other treatments.

13. Antibiotics: If your eczema gets infected, antibiotics can help.

14. Alitretinoin (Toctino): This is a medication used for chronic hand eczema that hasn’t responded to other treatments.

15. Immunomodulators: Drugs like tacrolimus and pimecrolimus are topical immunomodulators, which can help by altering the immune response that leads to inflammation.

16. Topical calcineurin inhibitors: These are non-steroidal medications that work similarly to immunomodulators.
