| Sumario: | Abstract Background Symptom control is a major concern in chronic urticaria. Histobulin™ is a histamine/immunoglobulin complex that has been approved for allergic rhinitis, bronchial asthma and chronic urticaria in some countries. Not only has the immunoglobulin/histamine complex been reported to be effective in allergic diseases, including chronic urticaria, but recently, the possibility of remission induction in chronic urticaria by the immunoglobulin/histamine complex has been reported. Case presentation Histobulin™ was administered until remission was induced instead of fixing the number of administrations in four cases of chronic urticaria. Two patients showed an early response and finished treatment with 12 injections of Histobulin™, and the other two patients showed a late response and were injected 43 and 46 times. Remission was induced successfully in all four cases. Conclusions Histobulin™ is not only effective but also induces remission in CSU. The Histobulin™ therapy protocol in CSU may be better if the treatment is continued until remission is achieved. Based on the responses of the patients, early responders and late responders were present. The progression of the disease during treatment consisted of a slow improvement phase and a rapid improvement phase. Uniquely, the appropriate allergy laboratory results, including blood eosinophil fraction, total IgE and eosinophil cationic protein level, were normal in all 4 cases. Further studies concerning the mechanisms of Histobulin™ may be needed. |
