Insights
Anemia is common in children with human immunodeficiency virus type 1 (HIV-1). Higher neopterin levels correlate with lower hemoglobin, suggesting immune activation contributes to anemia in HIV-1 patients.
Area of Science:
- Hematology
- Immunology
- Virology
Background:
- Anemia is a frequent complication in patients with human immunodeficiency virus type 1 (HIV-1) infection.
- Understanding the pathogenesis of anemia in HIV-1 is crucial for effective management.
Purpose of the Study:
- To investigate the relationship between immune activation markers and hemoglobin levels in children with severe hemophilia, particularly those with HIV-1 infection.
Main Methods:
- Assessed hemoglobin and urinary neopterin concentrations in 14 children with severe hemophilia (9 HIV-1 seropositive, 5 seronegative).
- Utilized Spearman's rank correlation to analyze the association between neopterin and hemoglobin levels.
Main Results:
- A significant negative correlation was found between urinary neopterin and hemoglobin concentrations (rs = -0.745, p = 0.007).
- This indicates that higher levels of immune activation (neopterin) are associated with lower hemoglobin levels.
Conclusions:
- Chronic immune activation, potentially involving cytokines like interferon gamma and tumor necrosis factor alpha, may play a role in the pathogenesis of anemia in HIV-1 infected children.
- Neopterin may serve as a marker for immune activation contributing to anemia in this population.
Abstract:
Anaemia is a frequent complication in patients with human immunodeficiency virus type 1 (HIV-1) infection. We tested 14 children with severe haemophilia (9 HIV-1 antibody seropositive CDC stage IIA, 5 seronegative) for haemoglobin and urinary neopterin concentrations and found a negative correlation between neopterin and haemoglobin (rs = -0.745, p = 0.007; Spearman's rank correlation). This finding suggests that chronic immune activation, possibly along with the release of specific cytokines such as interferon gamma and tumor necrosis factor alpha may be involved in the pathogenesis of anaemia.
