Abstract The aim of this work is to compare the immunological pattern in various types of malnutrition diseases by studying the hemoral immunity (the serum immunoglobulin and complement system) in different patterns of malnutrition: PEM, vitamin D deficiency rickets and iron deficiency anaemia. Furthermore a trial to evaluate the role of serum proteins and deficiency of elements in these diseases. This may help in the treatment of these cases. We conclude from this study that IgM, IgA, C3 and C4 were not affected in infantile rickets and iron deficiency anaemia. The serum albumin levels in the kwashiorkor and marasmic kwashiorkor patients, in this study were markedly reduced, while were less markedly deficient in the marasmic patients. The PEM patients had a significant deficient transferring serum levels. In our rachtic and iron deficient patients, there were slightly reduced serum levels of both albumin and transferring. This may due to be adequate intake of proteins and calories. In our PEM patients, there were significant deficiency of calcium, phosphorus, potassium, magnesium, iron, zinc and copper. This may be due to deficiency of albumin, reduced intake, malabsorption, or loss in repeated diarrhoea. In our rachitic patients, the serum levels of phosphorus only were markedly deficient while other elements like calcium, potassium, magnesium, iron, zinc and copper were slightly reduced. While the iron deficient patients had markedly deficient iron and slightly deficient of the other elements. |
