Norwegian scabies in a patient with AIDS
1Department of Medicine, Medical College of Ohio, Toledo 43699.
Summary
Norwegian scabies, a severe mite infection, can overwhelm individuals with weakened immune systems, particularly those with AIDS. Early diagnosis and treatment are crucial as it is highly contagious and curable.
Area of Science:
- Immunology
- Dermatology
- Infectious Diseases
Background:
- Cellular and humoral immunity are crucial for controlling Sarcoptes scabiei mite infections.
- High mite densities lead to Norwegian (crusted) scabies, a severe form of the disease.
Observation:
- Norwegian scabies cases are sporadically reported in patients with Acquired Immunodeficiency Syndrome (AIDS).
- The rash presentation in these patients can be misleading, appearing diffuse, papular, or psoriasiform.
Findings:
- Immunocompromised individuals, especially those with AIDS, are susceptible to severe scabies infections.
- Patients with Norwegian scabies can readily transmit the mite to others.
Implications:
- Norwegian scabies should be considered in the differential diagnosis of persistent papular or psoriasiform rashes in AIDS patients.
- Prompt diagnosis and treatment are essential for managing this curable but highly transmissible condition.
