Overview
Laboratory Findings
- Autologous serum skin test (ASST) and basophil activation test (BAT) are two tests that are capable of detecting any autoantibodies against IgE for FcεRI.[1][2]
- Although ASST is not a specific test, positive results can determine active disease, mast cells and basophils activation and possible reduction in basophils.
- Interestingly positive autologous serum skin test (ASST) could be related to better prognosis.
- Moreover positive autologous serum skin test (ASST) seems to be related to slower response to omalizumab.
- C-reactive protein (CRP) is also related to disease activity and treatment response in urticaria.[3][4][5]
- It's elevated level is also associated with positive autologous serum skin test (ASST) and elevated levels of erythrocyte sedimentation rate (ESR), leukocytes, neutrophils and IL-6.
- Elevated CRP is related to better response to oral cyclosporine therapy and conversely poor response to antihistamines.
- In contrast to other inflammatory conditions, urticaria patients usually present with lower quantitative level of CRP.
- Elevated level of IL-6 is related to disease activity in urticaria.[4]
- IL-18, one of the IL-1 family cytokines, has been present in serum specimens of nearly all patients with chronic spontaneous urticaria. Nevertheless more studies required to determine it's exact role in the pathogenesis of this subtype.[6][7]
