Popis: Abstract Background Current classification of chronic urticaria is primarily based on clinical presentation of skin manifestations. Hence, therapeutic treatment is primarily aimed locally for immediate symptom relief. We reason that limiting therapeutic strategies to the skin pathology might be inadequate since cellular activation and inflammation might be triggered remotely. Case presentation In this series two patients had exhausted all current treatments for recalcitrant urticaria but remained symptomatic. The first case was 26-year-old Caucasian female and the second was 63-year-old African American female. Both cases had frequent breakthrough urticaria requiring frequent pulsating courses of prednisone to control urticaria despite treatment with omalizumab and antihistamines. When inflammatory airway disease was discovered and managed with inhaled corticosteroid, urticaria is controlled much faster without the need of high dose immunosuppression over several years of observation. Coincidentally, autoimmune thyroiditis and anti-immunogobulin-E immunoglobulin-G titers dropped significantly in one case with sustained inhaled corticosteroid therapy. Conclusions We suggest a novel approach of controlling remote epithelial site inflammation in these two cases that resulted in sustained-control of urticaria symptoms without the need for systemic corticosteroids or immunosuppressant. The changes of autoimmune antibodies might be the consequences of tolerance breaking from chronic lower airway inflammation as observed in other epithelial inflammatory condition like in celiac disease and rheumatoid arthritis.
