• Urticaria, physical (inducible):Mechanical:
  • Urticaria factitia (most frequent form of physical urticaria)
  • Pressure Urticaria
  • Vibratory Urticaria/Angioedema.
• thermal:
  • Cold urticaria (contact type; second most common form of physical urticaria)
  • Thermal urticaria (heat contact urticaria)
• Electromagnetic waves:
  • Light urticaria (solar urticaria)
  • Radiolucent urticaria

Omalizumab: A literature review of 43 studies, case studies, case reports and analyses on the use of amalizumab in various diseases was conducted. Subtypes of chronically inducible urticaria (symptomatic dermographism, cold, heat, sun, water and pressure urticaria, vibratory angioedema, cholinergic urticaria and contact urticaria). This resulted in clear therapy effects with the strongest evidence in symptomatic dermographism, cold urticaria, sun urticaria (Maurer M et al. 2018)
