補體系統先天或後天缺陷導致免疫功能異常。最常見為C3缺乏，易發嚴重細菌感染。犬布列塔尼獵犬有遺傳性C3缺乏。
Feline immune-mediated diseases include IMHA (often secondary), ITP, pemphigus foliaceus, and immune-mediated polyarthritis. FIV causes progressive immunodeficiency increasing susceptibility to opportunistic infections and neoplasia. Vaccine-associated fibrosarcoma (FISS) involves adjuvant-triggered chronic inflammation at injection sites.

建議：維持量 LRS
類型：LRS
監測頻率：q1-2 週（免疫抑制初期）

建議數日內就診評估，非立即危及生命但不宜拖延 (evaluation within days recommended, not immediately life-threatening)
預後保留。反覆感染影響生活品質及壽命。需終生抗生素預防及積極治療感染。
Diagnostic Approach for Complement System Disorders
Assess for fever, joint swelling, skin lesions, lymphadenopathy, organ involvement
CBC, chemistry, ANA, rheumatoid factor, Coombs test, serum protein electrophoresis
Biopsy of affected tissue (skin, joint, kidney) with histopathology and immunofluorescence
