ABSTRACT
ABSTRACT Introduction: Hematologic abnormalities are common in HIV and involve all blood cell lineages. A study on cytopenias, as correlated with disease progression, can be valuable in resource-limited settings. This study aimed to determine the hematologic profile of HIV patients and its association with CD4 count and antiretroviral (ARV) treatment. Methods: This is a retrospective cohort study involving adult Filipino HIV patients with complete blood count (CBC) and CD4 count determinations prior to the initiation of ARV treatment and after ≥6 months of ARV treatment. Logistic regression was performed to determine the association between cytopenias and a CD4 count <200 cells/μL. Results: The study included 302 patients. Anemia was the most common cytopenia. Anemia and leukopenia were associated with an increased likelihood of having a CD4 count <200 cells/μL in ARV-naïve patients. In ARV-treated patients, leukopenia was associated with an increased probability of having a CD4 count <200 cells/μL. An increase in hemoglobin, white blood cell (WBC) and platelet counts was observed after ≥6 months of ARV treatment. Conclusion: Anemia and leukopenia can be used as markers of immune status in HIV-infected individuals and improvement in the CBC parameters can be used to assess response to ARV treatment. Routine monitoring of hematologic parameters is recommended.
