Low haemoglobin in haemophilia children is associated with chronic immune activation.
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.
