猫传染性腹膜炎(FIP):从"绝症"到可治疗,识别与用药认知更新
2026/10/3· 约 5 分钟读完· 28 个要点
FIP 曾被视为不治之症,近年的抗病毒研究与 RCT 改变了这一判断。这篇按 ABCD 指南与口服 GS-441524 随机对照试验,讲清症状识别、确诊路径与治疗现实。
一、FIP 到底是什么
FIP 由猫肠道冠状病毒(FECV)在个体内变异后引起,是一种免疫介导的血管炎性疾病,而不是简单的"传染病"——绝大多数携带冠状病毒的猫并不会发病[1]。
两类表现:
- 渗出型(湿性):腹水/胸水,肚子渐进性变大、呼吸变快变浅;
- 非渗出型(干性):眼部/神经症状、脏器肉芽肿,发热、消瘦、黄疸,诊断更难。
二、需要警惕的信号组合
- 幼猫(<2 岁)或多猫环境/收容所来源;
- 持续或反复发热,抗生素无效;
- 食欲下降、体重不增或下降、精神沉郁;
- 腹部逐渐膨大(湿性)、呼吸费力(胸水);
- 眼内发炎、抽搐、走路不稳(干性);
- 近期有应激事件(搬家、绝育、新猫入户、寄养)。
三、确诊不是靠单一化验
ABCD(欧洲猫病顾问委员会)指南强调:FIP 的诊断需要综合信号、临床症状、血液生化(如球蛋白升高、A:G 比)、影像学/积液分析与病原检测,单一检测无法直接定论[1]。
四、治疗:认知已经被数据改写
- 2024 年一项前瞻随机对照研究比较了口服 GS-441524 42 天与推荐的 84 天方案,结果显示在有渗出的 FIP 猫中,42 天方案的疗效与 84 天相当[2]

👉 ABCD 指南:FIP 的免疫介导机制、综合诊断路径与管理原则。
展开原文摘要(英文,1346 字)
Feline coronavirus (FCoV) is a ubiquitous RNA virus of cats, which is transmitted faeco-orally. In these guidelines, the European Advisory Board on Cat Diseases (ABCD) presents a comprehensive review of feline infectious peritonitis (FIP). FCoV is primarily an enteric virus and most infections do not cause clinical signs, or result in only enteritis, but a small proportion of FCoV-infected cats develop FIP. The pathology in FIP comprises a perivascular phlebitis that can affect any organ. Cats under two years old are most frequently affected by FIP. Most cats present with fever, anorexia, and weight loss; many have effusions, and some have ocular and/or neurological signs. Making a diagnosis is complex and ABCD FIP Diagnostic Approach Tools are available to aid veterinarians. Sampling an effusion, when present, for cytology, biochemistry, and FCoV RNA or FCoV antigen detection is very useful diagnostically. In the absence of an effusion, fine-needle aspirates from affected organs for cytology and FCoV RNA or FCoV antigen detection are helpful. Definitive diagnosis usually requires histopathology with FCoV antigen detection. Antiviral treatments now enable recovery in many cases from this previously fatal disease; nucleoside analogues (e.g., oral GS-441524) are very effective, although they are not available in all countries.
