Biologic abnormalities were also found: 1) 25 patients have a microcytic hypochromic anemia which was iron-deficiency in 18 of them; 2) leukocytosis was shown in 21 patients with neutrophil predominance in 16 of them; 3) eosinophilia was found in 3 patients; 4) C-reactive protein (CRP) had a value between 5 and 360 mg/l with an average of 74; and 5) the detection of Mycobacterium tuberculosis and the tuberculin skin testing performed for 13 patients were negative in all cases. This evidence concerns the gene CRP and anemia (phenotype).
