BENCOMO HERNANDEZ, Antonio A et al. Concentration of IgG autoantibodies on red blood cells and response to treatment in autoimmune hemolytic anemia. Rev Cubana Hematol Inmunol Hemoter [online]. 2013, vol.29, n.2, pp.173-182. ISSN 0864-0289.

Introduction: there is not enough evidence that relates the response to treatment with the pattern of autoantibodies or their concentration on red blood cells in patients with autoimmune hemolytic anemia. Objective: to investigate the association of the response to treatment and the remission of the disease with the concentration of IgG autoantibodies on red blood cells at the beginning of the disease. Methods: a retrospective study in 44 adult patients with idiopathic warm autoimmune hemolytic anemia with only IgG autoantibodies was carried out in order to relate the response to treatment to the immunoprotein pattern of red blood cells, the IgG autoantibodies concentration on red blood cells, the hemoglobin level and the reticulocyte count. Results: association was not observed between the immunoprotein pattern, the hemoglobin level, the reticulocyte count and the quantitation of IgG on red blood cells, with the response to treatment with prednisone, administration of second-line treatment and the remission of the disease; although, the number of IgG molecules on red blood cells was 1,4 times higher in patients with no remission of the disease to those with remission. Conclusions: the immunoprotein pattern, the hemoglobin level, the reticulocyte count and the quantitation of IgG on red blood cells at the beginning of the disease are not a prognostic marker of the response to treatment.
