The study comprised 36 patients who were divided into two groups. In the first one, there were acute or chronic infectious diseases and the second was a control group. In all of them, the following laboratory counts were done: hemoglobin, hematocrit, leukocyte; also, measurement of protein electrophoresis, of serum iron and of total fixation capacity of iron (transferrin). The procedure was that of a blind study, so that the laboratories responsible for the measurements were not given any clinical information on the different patients. Hypochromic anemia of different degrees of severeness was reported in all infected patients and was attributted to nutritional and infectious factors. In spite of decreased levels of hemoglobin and iron, it was shown that transferrin did not rise, but otherwise, dropped in these patients; therefore, the capacity to convey and fix iron is decreased. This would be a fact resulting in a greater susceptibility, to suffer infections, as has been confirmed in previous studies. A close relationship was found at pediatric level among hypochromic anemia, drop in transferrin levels, poor nutrition and increase of infectious diseases.
该研究纳入了36名患者,他们被分为两组。第一组患有急性或慢性传染病,第二组为对照组。对所有患者都进行了以下实验室检查:血红蛋白、血细胞比容、白细胞计数;还进行了蛋白质电泳、血清铁和铁总结合能力(转铁蛋白)的测定。该研究采用盲法,因此负责测量的实验室未获得任何关于不同患者的临床信息。所有感染患者均报告有不同程度的低色素性贫血,这归因于营养和感染因素。尽管血红蛋白和铁水平降低,但结果显示这些患者的转铁蛋白并未升高,反而下降;因此,铁的转运和结合能力降低。正如先前研究所证实的,这一事实会导致更容易感染。在儿科层面发现低色素性贫血、转铁蛋白水平下降、营养不良和传染病增加之间存在密切关系。
