Recent years have seen an increase in use of mepolizumab and other biological therapies for the treatment of severe eosinophilic asthma. A few cases of paradoxical responses to mepolizumab therapy have now been reported and are hypothesised as being a response to immune complex formation. We present a case of mepolizumab-induced alopecia in a patient with paradoxical adverse response to mepolizumab given for severe eosinophilic asthma. We postulate this could be secondary to autoimmune mechanisms and that it could help herald poor response to treatment, thereby facilitating early identification of patients having paradoxical responses.
近年来,美泊利单抗及其他生物疗法在重度嗜酸性粒细胞性哮喘治疗中的应用有所增加。现已报告了几例美泊利单抗治疗出现矛盾反应的病例,据推测这是对免疫复合物形成的一种反应。我们报告了1例因重度嗜酸性粒细胞性哮喘接受美泊利单抗治疗出现矛盾不良反应的患者发生美泊利单抗诱发脱发的病例。我们推测这可能继发于自身免疫机制,并且可能预示治疗反应不佳,从而有助于早期识别出现矛盾反应的患者。
