To study the iron profile and find out an accurate diagnostic tool which reflects iron status in different types of infection in severely malnourished children aged 12 months to 71 months.
Hundred and Eight (108) children of whom 72 children were infected and 36 non infected severely malnourished children according to WHO criteria in the age group of 12-71 months were interrogated. 36 healthy control in the same age group were also interrogated.
Mean serum iron, total iron binding capacity (TIBC), ferritin concentration in normal children were significantly higher (P<0.001) than non-infected severely malnourished children. On the other hand mean serum ferritin concentration was significantly higher (P<0.001) in infected group than non-infected group but still lower than normal. Mean serum TIBC concentration significantly reduced in severely malnourished children than normal children but no significant difference was observed between non-infected and infected group. Mean serum iron, and transferrin saturation were significantly reduced (P<0.05) in parasitic infestation.
Severely malnourished children had reduced mean serum iron profile. Parasitic infestation influenced the marked reduction of mean serum iron concentration and transferrin saturation level. Mean serum iron concentration was reduced in acute respiratory infection(ARI) and parasitic infestation than other infections. Serum ferritin concentration was elevated in all types of infection as acute phase protein but still lower than normal. So Iron, TIBC and Transferin saturation <16% constitute good evidence for iron deficiency in both infected and non-infected severely malnourished children.
研究铁谱,寻找一种准确的诊断工具,反映不同类型感染在 12 个月至 71 个月大严重营养不良儿童中的铁状态。
根据世卫组织标准,对 12-71 个月大的 72 名感染儿童和 36 名未感染的严重营养不良儿童进行询问,108 名儿童中有 108 名,此外还对 36 名同年龄组的健康对照进行询问。
正常儿童的血清铁、总铁结合力(TIBC)和铁蛋白浓度均值明显高于(P<0.001)未感染的严重营养不良儿童。另一方面,感染组的血清铁蛋白浓度均值明显高于(P<0.001)未感染组,但仍低于正常水平。严重营养不良儿童的血清 TIBC 浓度均值明显低于正常儿童,但未感染组和感染组之间无显著差异。血清铁和转铁蛋白饱和度在寄生虫感染中明显降低(P<0.05)。
严重营养不良儿童的血清铁谱均值降低。寄生虫感染会影响血清铁浓度和转铁蛋白饱和度的显著降低。急性呼吸道感染(ARI)和寄生虫感染的血清铁浓度比其他感染降低。血清铁蛋白浓度在所有类型的感染中作为急性期蛋白升高,但仍低于正常水平。因此,铁、TIBC 和转铁蛋白饱和度<16%,在感染和未感染的严重营养不良儿童中均构成缺铁的有力证据。
