中性粒细胞缺乏症 中国就医指南

Neutropenia is a hematologic disorder characterized by an abnormally low absolute neutrophil count (ANC) — typically defined as fewer than 1,500 neutrophils per microliter (μL) of blood in adults. Severe neutropenia is diagnosed when ANC falls below 500/μL, significantly increasing susceptibility to bacterial and fungal infections. Neutrophils are the most abundant granulocytes and serve as the body’s first-line defense against invasive pathogens; thus, their deficiency compromises innate immunity. Pathogenesis varies widely and includes decreased bone marrow production (e.g., due to chemotherapy, radiation, aplastic anemia, or congenital disorders like Kostmann syndrome), accelerated peripheral destruction (e.g., autoimmune neutropenia, drug-induced immune reactions), or abnormal neutrophil distribution (e.g., margination in sepsis or hypersplenism). Secondary causes predominate clinically — chemotherapy for malignancies accounts for over 80% of acquired cases in oncology settings. Other contributors include viral infections (e.g., HIV, hepatitis, EBV), nutritional deficiencies (vitamin B12, folate), autoimmune diseases (SLE, rheumatoid arthritis), and certain medications (e.g., antithyroid drugs, sulfonamides, clozapine). Epidemiologically, neutropenia affects approximately 1–2% of hospitalized adults, with incidence rising sharply among cancer patients undergoing myelosuppressive therapy. In community settings, chronic idiopathic neutropenia occurs in ~0.03% of the general population, more commonly in older adults and females. Risk factors include age >65 years, active malignancy, recent chemotherapy or stem cell transplantation, HIV infection, autoimmune disease, splenomegaly, and prolonged use of high-risk medications. Quality of life is profoundly impacted: recurrent febrile episodes, oral ulcers, gingivitis, skin abscesses, and pneumonia lead to frequent hospitalizations, treatment delays, anxiety about infection, social isolation, and reduced functional capacity. Patients often report fatigue, diminished work productivity, and emotional distress linked to unpredictability of febrile neutropenic events. Chronic neutropenia may also contribute to long-term complications such as periodontal disease and growth impairment in pediatric populations. Early diagnosis via complete blood count (CBC) with differential and ANC calculation is essential; further evaluation includes bone marrow aspiration/biopsy, autoantibody testing, cytogenetics, and infectious workup depending on clinical context. Prognosis is generally favorable in transient or mild cases but depends critically on underlying etiology — severe congenital or clonal neutropenias carry higher risks of transformation to myelodysplastic syndrome or acute myeloid leukemia.
