Serum immunoglobulin E (IgE) and IgG levels are extremely high in patients with crusted scabies, yet the immune reaction does not seem to be protective. Cell-mediated immunity in classic scabies demonstrates T4-cell predominance in the dermal infiltrate, while one study suggests a T8-cell predominance in crusted scabies.
