To evaluate the anti-inflammatory cytokine interleukin-13 (IL-13) for the treatment of uveitis.
Uveitis was induced in monkeys by immunisation with human retinal S-antigen. Starting at the onset of disease, the animals were treated with IL-13 at 25 micrograms/kg, or vehicle control, injected subcutaneously once a day for 28 days. Intraocular inflammation was scored by indirect ophthalmoscopy for a period of 56 days. Circulating leucocyte levels were monitored.
Uveitis started unilaterally in all but one animal. IL-13 inhibited inflammation both in the eyes in which the disease was present when the treatment was initiated (p = 0.0001), and in the contralateral initially negative eyes (p = 0.0001). After cessation of therapy, there was a progressive increase of inflammation in the IL-13 treated group. However, the beneficial effect of IL-13 extended into the 4 week follow up period. IL-13 produced an increase in circulating polymorphonuclear neutrophils and a decrease in lymphocytes.
Administration of IL-13 appears to be a promising modality of treatment for severe uveitis.
评估抗炎细胞因子白细胞介素 - 13(IL - 13)治疗葡萄膜炎的效果。
通过用人视网膜S抗原免疫诱导猴子发生葡萄膜炎。从疾病发作开始,动物分别接受25微克/千克的IL - 13治疗或赋形剂对照,每天皮下注射一次,持续28天。通过间接检眼镜检查对眼内炎症进行评分,为期56天。监测循环白细胞水平。
除一只动物外,所有动物的葡萄膜炎均单侧发病。IL - 13在治疗开始时已发病的眼睛中抑制炎症(p = 0.0001),在对侧最初未发病的眼睛中也抑制炎症(p = 0.0001)。治疗停止后,IL - 13治疗组的炎症逐渐加重。然而,IL - 13的有益作用持续到4周的随访期。IL - 13使循环中的多形核中性粒细胞增加,淋巴细胞减少。
给予IL - 13似乎是治疗严重葡萄膜炎的一种有前景的方法。
