Comment on: Homocysteine and vitamin B12 status and iron deficiency anemia in female university students from Gaza, Palestine

vitamin B12. Therefore, the results of the study of Sirdah et al. Iron is themost abundant heavymetal in the earth’s crust and is required by almost all organisms.1 In the human body iron is required by and present in all cells and has several vital functions.2 Anemia due to iron deficiency is the commonest type of nutritional anemia worldwide, and occurs when body iron stores become inadequate for the needs of normal erythropoiesis. Iron deficiency anemia (IDA) results from an imbalance between iron intake and iron losses or utilization.3 Vitamin B12 deficiency is another type of nutritional deficiency that is encountered among the elderly of rich countries, but it is more prevalent in poorer populations around the world.4 On the other hand, increased levels of homocysteine (hyperhomocysteinemia) are found to be associated with coronary atherosclerosis and cerebrovascular disorders.5 In the current issue of the Revista Brasileira de Hematologia e Hemoterapia, Sirdah et al. present original data about serum homocysteine and vitamin B12 status in female university students (18–22 years old) diagnosed with IDA.6 The authors explored the association between the markers of IDA (serum ferritin, hemoglobin concentration, red blood cellmass) and the serum levels of homocysteine and vitamin B12. The importance of the study can be viewed in respect to different aspects. The study is among the very few scientific works that tried to find an association between anemia, specially IDA, homocysteine, and vitamin B12. Also it covers a very vulnerable target group for developing IDA, females of the childbearing age. Moreover, the study was carried out in the Gaza Strip of Palestine where
