Nematode Dermatitis

Nematode dermatitis, also known as “creeping eruption” or “ground itch,” is a skin condition caused by tiny parasitic worms called nematodes. These worms can burrow into your skin, leading to itching, redness, and discomfort. In this article, we’ll explain nematode dermatitis in plain English, covering types, causes, symptoms, diagnosis, treatments, drugs, and more.

Types of Nematode Dermatitis:

There are two main types of nematode dermatitis:

1. Cutaneous Larva Migrans (CLM): This type occurs when dog or cat hookworm larvae penetrate human skin. It’s the most common form of nematode dermatitis.
2. Swimmer’s Itch: Swimmer’s itch is caused by waterfowl schistosomes, a type of nematode. It affects people who swim or wade in contaminated freshwater.

Causes of Nematode Dermatitis:

1. Walking Barefoot: Nematode larvae often lurk in sandy or moist soil. Walking barefoot can make you susceptible to infestation.
2. Playing in Sand: Children who play in sandboxes or on the beach are at risk of nematode dermatitis.
3. Pets: Having dogs or cats that carry hookworms can increase the risk.
4. Swimming in Contaminated Water: Lakes or ponds with waterfowl can expose swimmers to swimmer’s itch.
5. Poor Hygiene: Infrequent handwashing after outdoor activities can lead to nematode infection.
6. Gardening: Handling contaminated soil while gardening can introduce nematodes to your skin.
7. Beach Activities: Lounging on sandy shores or participating in beach sports may result in exposure.
8. Exposure to Infected Soil: Camping or hiking in areas with infected soil can lead to infestation.
9. Occupational Exposure: Certain jobs, like farming or construction, may increase the risk of contact with infected soil.
10. Lack of Footwear: Not wearing shoes in affected areas can put your feet at risk.
11. Contaminated Clothing: Clothes exposed to contaminated soil can transfer nematodes to your skin.
12. Poor Sanitation: Inadequate sanitation facilities in some regions can contribute to nematode spread.
13. Tropical Regions: Nematode dermatitis is more common in tropical and subtropical climates.
14. Inadequate Waste Disposal: Improper disposal of feces can contaminate the environment.
15. Playing with Pets: Children playing with infected pets can contract CLM.
16. Using Infected Bedding: Sleeping on bedding infested with nematodes can lead to infection.
17. Contact with Contaminated Water: Swimmer’s itch can occur after swimming in infected waters.
18. Inadequate Foot Protection: Open-toed shoes or sandals can expose your feet to nematode-infested soil.
19. Contaminated Bathrooms: Shared bathrooms in certain settings may pose a risk.
20. Lack of Pest Control: Insufficient measures to control pests like rodents can increase exposure.

Common Symptoms of Nematode Dermatitis (Creeping Eruption):

Nematode dermatitis can cause various symptoms, including:

1. Itching: The primary symptom is intense itching at the site of infection.
2. Redness: The affected area may become red and inflamed.
3. Raised Tracks: You might notice raised, winding tracks on your skin.
4. Blisters: In severe cases, blisters may form.
5. Pain or Burning: Some people experience pain or a burning sensation.
6. Swelling: Swelling around the affected area is possible.
7. Rash: A rash may develop, resembling hives.
8. Infection: Scratching can lead to secondary bacterial infections.
9. Fever: In rare instances, a fever may occur.
10. Fatigue: Discomfort and itchiness can lead to fatigue.
11. Restlessness: The itching may cause difficulty sleeping.
12. Anxiety: Prolonged symptoms can cause anxiety and distress.
13. Pus: Pus-filled bumps may develop if the area becomes infected.

20. Difficulty Walking: If the feet are affected, walking can become painful.

Diagnostic Tests for Nematode Dermatitis:

Diagnosing nematode dermatitis typically involves clinical evaluation and may include:

1. Physical Examination: Your healthcare provider will inspect the affected area and ask about your symptoms and recent activities.
2. Medical History: Providing information about your recent activities, travels, and pet interactions is crucial.
3. Skin Scraping: A skin scraping may reveal nematode larvae under a microscope.
4. Biopsy: In rare cases, a skin biopsy may be necessary for confirmation.
5. Blood Tests: Blood tests can help rule out other conditions with similar symptoms.
6. Dermoscopy: Dermoscopy may aid in identifying the characteristic tracks left by the larvae.
7. Patch Testing: Patch testing can help confirm the diagnosis in some cases.
8. Skin Culture: Culturing the larvae from a skin sample can confirm the presence of nematodes.
9. Imaging: In severe or complicated cases, imaging tests like ultrasound may be necessary.
10. Allergy Testing: Allergy testing can help determine if an allergic reaction is contributing to the symptoms.

Treatment Options for Nematode Dermatitis:

Nematode dermatitis can be treated effectively. Here are 30 treatments to consider:

1. Topical Anti-Parasitic Cream: Applying anti-parasitic creams directly to the affected area can kill the larvae.
2. Oral Anti-Parasitic Medications: Your healthcare provider may prescribe oral medications to eliminate the nematodes.
3. Steroid Cream: Steroid creams can reduce itching and inflammation.
4. Antibiotics: If there’s a secondary bacterial infection, antibiotics may be necessary.

6. Pain Relievers: Over-the-counter pain relievers can alleviate discomfort.
7. Cool Compresses: Applying a cool, damp cloth to the affected area can soothe itching.
8. Elevating Affected Limbs: Elevating the legs, if affected, can reduce swelling.
9. Avoid Scratching: Resisting the urge to scratch is crucial to prevent infection.
10. Good Hygiene: Keeping the affected area clean is essential.
11. Trim Nails: Short nails can minimize skin damage from scratching.
12. Corticosteroid Cream: In severe cases, corticosteroid creams may be prescribed.
