Norwegian Scabies

Norwegian scabies, also known as crusted scabies or hyperkeratotic scabies, is a highly contagious skin condition caused by the Sarcoptes scabiei mite. Unlike typical scabies, Norwegian scabies is characterized by a severe infestation of mites and an overwhelming skin reaction. In this article, we’ll provide plain English explanations of Norwegian scabies, its types, causes, symptoms, diagnostic tests, treatments, and medications to help you understand this condition better.

Types of Norwegian Scabies:

There is only one type of Norwegian scabies, but it can vary in severity from person to person. It’s essential to identify the condition early to prevent its spread and complications.

Causes of Norwegian Scabies

1. Weakened Immune System: A compromised immune system due to conditions like HIV/AIDS or certain medications can increase the risk of Norwegian scabies.
2. Close Contact: Prolonged, close contact with an infected person can facilitate the transmission of scabies mites.
3. Crowded Living Conditions: Overcrowded living spaces, such as nursing homes or homeless shelters, can make it easier for the mites to spread.
4. Poor Hygiene: Inadequate personal hygiene may increase susceptibility to scabies infestation.
5. Age: Norwegian scabies is more common among the elderly due to weakened immune systems.
6. Mental Illness: People with conditions affecting their mental capacity may not recognize or seek treatment for scabies.
7. Chronic Illness: Conditions like leukemia, which weaken the immune system, can make individuals more susceptible.
8. Long-Term Steroid Use: Prolonged use of steroids can suppress the immune system, making it easier for mites to thrive.
9. Bed Sharing: Sharing a bed with an infected person can lead to the transmission of scabies.
10. Occupational Exposure: Certain jobs, like healthcare workers or caregivers, may have a higher risk of contracting scabies.
11. Travel to Endemic Areas: Visiting regions where scabies is prevalent can increase your risk.
12. Poor Living Conditions: Living in unsanitary environments may encourage mite infestations.
13. Sharing Personal Items: Sharing clothing, towels, or bedding with an infected person can transfer mites.
14. Malnutrition: Poor nutrition can weaken the immune system, making you more susceptible.
15. Lack of Awareness: Not recognizing the symptoms or seeking timely treatment can lead to severe infestations.
16. Chronic Skin Conditions: Skin problems like eczema can provide an entry point for scabies mites.
17. Substance Abuse: People with substance abuse issues may neglect personal hygiene, increasing the risk.
18. Immunodeficiency Disorders: Conditions like lupus or rheumatoid arthritis can compromise the immune system.
19. Organ Transplants: Patients taking immunosuppressive drugs post-transplant are at risk.
20. Genetic Factors: Some individuals may be genetically predisposed to severe scabies infestations.

19. Emotional Distress: Severe itching and visible symptoms can cause anxiety and distress.
20. Limited Mobility: Thickened skin can restrict movement.

Diagnostic Tests for Norwegian Scabies

1. Skin Scraping: A healthcare provider will scrape off a tiny sample of skin to check for mites or their eggs.
2. Microscopic Examination: The skin sample is examined under a microscope to identify scabies mites.
3. Dermatoscopy: A dermatoscope can help visualize mites or burrows on the skin’s surface.
4. Skin Biopsy: In some cases, a small piece of affected skin is removed for examination.
5. Blood Tests: Blood tests may be performed to check for underlying conditions or infections.
6. Polymerase Chain Reaction (PCR): PCR tests can detect scabies DNA in skin samples.
7. Tzanck Smear: This test can reveal the presence of mites, eggs, or feces on a skin sample.
8. Skin Culture: A culture may be done to identify bacterial infections in open sores.
9. Allergy Testing: To rule out other skin conditions that may mimic scabies symptoms.
10. X-rays: In severe cases, X-rays may be used to check for bone involvement.
11. Skin Swabs: Swabs of the affected skin can be cultured for bacteria.
12. Skin Biopsy: A small piece of skin is removed and examined under a microscope.
13. Patch Testing: To identify allergic reactions to scabies mites.
14. Skin Prick Test: To check for allergies to scabies antigens.
15. Skin pH Test: Scabies can alter skin pH levels, which can be measured.
16. Skin Reflectance Spectroscopy: Measures changes in skin color and texture.
17. Ultrasound: To evaluate deeper tissue involvement in severe cases.
18. Magnetic Resonance Imaging (MRI): For assessing neurological symptoms.
19. CT Scans: Used when there is suspicion of internal organ involvement.
20. Eosinophil Count: A blood test to check for elevated eosinophils, which may indicate an allergic response to mites.
