摘要嗜酸性脓疱性毛囊炎(EPF)的临床特征是躯干、四肢和面部的嗜酸性聚集性毛囊性丘疹和脓疱。组织学表现为嗜酸性粒细胞滤泡浸润。大多数患者的血嗜酸性粒细胞计数升高。口服米诺环素。非甾体类抗炎药、二氨基二苯砜和皮质类固醇可诱导缓解。我们报告两名日本男子与EPF谁反应不佳,以通常的治疗。静脉注射重组干扰素-γ(riFN-γ)。每日5 × 105至2 × 106日本参考单位(JRU)(1 JRU大致相当于4 NIH单位),持续7天,清除了皮肤病变,并使2例患者的外周嗜酸性粒细胞计数恢复正常。然而,在停用rIFN-γ后2-3天,病变复发。这两名患者每周接受一次或两次静脉注射rIFN-γ,持续近1年,无全身副作用。逆转录聚合酶链反应显示rIFN-γ治疗后外周血单个核细胞中白细胞介素5(IL-5)mRNA的表达降低。rIFN-γ可能成为治疗难治性EPF的首选,但需要进一步研究。它可能通过干扰2型T辅助细胞的免疫功能起作用,包括负责嗜酸性粒细胞生长和分化的IL-5产生。
Summary Eosinophilic pustular folliculitis (EPF) is characterized clinically by pruritic grouped follicular papules and pustules on the trunk, limbs, and face, and. Histologically by follicular infiltration with eoslnophils. The blood eosinophil count is elevated in most patients. Oral minocycline. Nonsteroidal anti‐inflammatory drugs, diamino diphenyl sulphone and corticosteroids may induce remission. We report two Japanese men with EPF who responded poorly to the usual therapy. Intravenous injections of recombinant interferon‐γ (riFN‐γ). 5 × 105 to 2 × 106 Japan Reference Unit (JRU) (1 JRU roughly corresponds to 4 NIH units) daily for 7 days, cleared the skin lesions and returned the peripheral eosinophil counts to normal in both patients. However, the lesions recurred 2–3 days after rIFN‐γ was stopped. Both patients have received intravenous rIFN‐γ once or twice a week for nearly 1 year without systemic side‐effects. Reverse transcripta sepolymerase chain reaction revealed a decreased expression of interleukin 5 (IL‐S) mRNA in peripheral mononuclear cells after the rIFN‐γ therapy. rIFN‐γ may become the treatment of choice in recalcitrant EPF, although further studies are needed. It may work by interfering with the immunological function of type 2 T‐helper cells, including IL‐5 production responsible for the growth and differentiation of eosinophils.
