Does AIDS cause a decrease or increase in white blood cell count?

Introduction
In the early stage after HIV infection, transient toxemic symptoms may occur. A complete blood count (CBC) may reveal mild decreases in white blood cells and platelets. In the middle to late stages of the disease, CBC typically shows leukopenia, along with varying degrees of reduction in hemoglobin, red blood cells, and platelets.
In general, patients with AIDS exhibit leukopenia (reduced white blood cell count). AIDS is a chronic infectious disease caused by human immunodeficiency virus (HIV) infection. Following viral infection, HIV preferentially targets and destroys CD4+ T lymphocytes, leading to progressive deterioration of immune function and subsequent development of various opportunistic infections and malignancies.
Currently, AIDS remains an incurable disease, and no established therapeutic regimen can achieve complete viral eradication or cure. During the early phase of HIV infection, transient systemic symptoms resembling sepsis may occur. Routine blood tests at this stage may reveal mild reductions in white blood cell and platelet counts.
In the intermediate to late stages of the disease, complete blood count (CBC) typically shows leukopenia, often accompanied by varying degrees of anemia (reduced hemoglobin and red blood cell count) and thrombocytopenia (reduced platelet count). However, leukopenia observed on CBC lacks diagnostic specificity for AIDS; therefore, diagnosis requires comprehensive evaluation incorporating epidemiological history, clinical manifestations, and confirmatory laboratory testing.
