摘要:

目的 探讨以IgE和嗜酸粒细胞升高伴多发淋巴结肿大为主要表现的IgG4相关性疾病的临床特点和治疗方案。方法 回顾性分析1例以IgE和嗜酸粒细胞升高伴多发淋巴结肿大为主要表现的IgG4相关性疾病患者的临床资料、诊疗经过并复习相关文献。结果 患者男性,24岁,双侧腹股沟淋巴结肿大2年余入院。结合临床表现、血IgG4检验、病理结果,诊断为IgG4相关性疾病。治疗方案给予强的松20 mg, 1次/日,枸橼酸托法替布片5 mg, 2次/日,根据复查血检验指标和超声结果调整剂量,最终随访患者症状明显改善。结论 lgG4相关性疾病常表现为显著升高的血清IgG4水平和肿块样病灶,合并IgE和嗜酸粒细胞升高的较少见, 但近期研究发现IgE和嗜酸性粒细胞在IgG4相关性疾病中发挥了重要作用。治疗方案以糖皮质激素为一线药物,靶向药物如托法替布可能有潜在的治疗作用,拓展了IgG4相关性疾病治疗的新思路。

Abstract:

Objective To explore the clinical features and treatment of immunoglobulin G4 (IgG4)-related diseases characterized by increased immunoglobulin E (IgE) level and eosinophilic count with multiple lymphadenopathy. Methods The clinical data, diagnosis and treatment process of a patient with IgG4-related disease characterized by increased IgE level and eosinophilic count with multiple lymphadenopathy were retrospective analyzed, and related literatures were reviewed. Results A 24-year-old male patient was admitted with the enlargement of bilateral inguinal lymph nodes for more than 2 years. The clinical manifestations, IgG4 test and pathology results suggested the diagnosis of IgG4-related disease. The therapeutic regimen was 20 mg prednisone orally once a day and 5 mg Tofacitinib citrate tablets orally twice a day. The dosage was adjusted according to the blood test and ultrasound results, and the symptoms of the patient were significantly improved at the final follow-up visit. Conclusion IgG4-related diseases are often characterized by significantly elevated serum IgG4 levels and lump-like lesions. Increased IgE level and eosinophil count are rarely observed in cases of IgG4-related diseases, although their important roles have been recently identified. Glucocorticoids are the first-line drugs, and targeted drugs like Tofacitinib may have potential therapeutic effects on IgG4-related diseases, which expand the new idea of the treatment.
