Introduction: Urticaria is a frequent and heterogeneous skin disease characterised by the development of wheals (hives), angioedema, or both. Chronic urticaria is characterised by the occurrence of wheals lasting less than 24 hours, with or without angioedema occurring daily or almost daily lasting more than six weeks. The two subtypes of chronic urticaria are Chronic Spontaneous Urticaria (CSU) and Chronic Inducible Urticaria (CIU). Autologous Serum Skin Test (ASST) is the simplest and the best in-vivo clinical test for the detection of basophil histamine- releasing activity. ASST has a sensitivity of approximately 70% and a specificity of 80%. Aim: To study the association between clinico-epidemiological features of CSU with positive and negative ASST. Materials and Methods: The cross-sectional study was conducted on 80 clinically diagnosed cases of CSU attending the Department of Dermatology Venereology Leprology Outpatient Department at Mahatma Gandhi Memorial Hospital (Kakatiya Medical College), Warangal, Telangana, India; during the period of January 2016 to September 2017. The detailed history was taken; complete physical and cutaneous examination and laboratory investigations like Complete Blood Picture (CBP), Absolute Eosinophil Count (AEC), Erythrocytic Sedimentation Rate (ESR), Thyroid Function Test (TFT) were carried out. ASST was done and read after 30 minutes. Chi- square test was applied and the results analysed using Statistical Package for the Social Sciences (SPSS) version 10.0. Results: Out of total 80 patients included in the study, ASST was positive in 36 (45%) and negative in 44 (55%). ASST positive patients showed longer duration of the disease with increased frequency of attacks and longer duration of wheals. However, both ASST positive and negative groups did not show statistically significant difference in the age of occurrence, gender, angioedema, dermographism. Conclusion: Autoimmune urticaria has no distinctive clinical features. ASST positive, autoimmune urticaria patients have more severe disease with greater impact on quality of life. Thus, they may need more aggressive treatment.

Background. Chronic urticaria is defined as urticaria persisting daily for more than six weeks. A significant number of patients had autoimmune basis where autologous serum skin test is widely used for detection of chronic autoimmune urticaria. Objectives. To estimate the frequency of autoimmune urticarial in Iraqi patients utilizing the autologous serum skin test and to evaluate its results with the variable clinical features of chronic idiopathic urticaria. Methods. In this prospective study, 54 patients with chronic idiopathic urticaria were investigated with autologous serum skin test where its results were examined with the different clinical parameters of chronic autoimmune urticaria. Results. Twenty two patients (40.7%) out of 54 patients with chronic idiopathic urticarial had positive autologous serum skin test. Statistical analysis of the clinical variables did not show a significant difference between patients with positive and negative autologous serum skin test except for the distribution of wheals on the face and extremities which was significantly associated with positive autologous serum skin test results (P value 0.004). Conclusion. Autologous serum skin test is a simple, office-based test for detecting chronic autoimmune urticaria patients who have no distinctive clinical features differentiating them from chronic idiopathic urticaria patients.

Previous studies indicate that 25–45% of chronic urticaria patients have an autoimmune etiology. Autologous serum skin test (ASST) and autologous plasma skin test (APST) are simple tests for diagnosing chronic autoimmune urticaria (CAU). However, there are still some questions about the specificity of these tests. This study consisted of 50 patients with chronic spontaneous urticaria (CSU) and 50 sex- and age-matched healthy individuals aged 18 years, and older. A total of 31 (62%) patients and 5 (10%) control patients had positive ASST; 21 (42%) patients and 3 (6%) control patients had positive APST. Statistically significant differences were noted in ASST and APST positivity between the patient and control groups (ASSTP<0.001; APSTP<0.001). Thirteen (26%) patients and 5 (10%) control patients had antithyroglobulin antibodies or antithyroid peroxidase antibody positivity. No statistically significant differences were noted in thyroid autoantibodies between the patient and control groups (anti-TGP=0.317; anti-TPOP=0.269). We consider that the ASST and APST can both be used asin vivotests for the assessment of autoimmunity in the etiology of CSU and that thyroid autoantibodies should be checked even when thyroid function tests reveal normal results in patients with CSU.
