The effect of iron deficiency anaemia (IDA) on CD71 expression by peripheral blood lymphocytes was studied in 43 children with iron deficiency anaemia. 18 healthy age‐matched children were selected as the control group. 11 children with β‐thalassaemia trait were also studied. Lymphocytes bearing CD71 were enumerated by flow cytometric analysis of peripheral blood. At diagnosis, CD71+ peripheral lymphocytes (mean ± SE) was 5.90 ± 0.76% in patients with IDA and 12.60 ± 0.98% in healthy controls (P = 0.000). In β‐thalassaemia trait patients the peripheral blood CD71+ lymphocytes were 7.80 ± 1.20%. In IDA patients there was a statistically significant correlation between the levels of CD71+ peripheral lymphocytes and haemoglobin value (P = 0.000). In 19 patients studied at days 0 and 30 of oral iron therapy, the number of peripheral blood CD71+ lymphocytes was shown to be increased from 5.90 ± 0.76% to 12.11 ± 1.21%. In severe IDA presence of a limited number of CD71+ peripheral blood lymphocytes indicated that severe IDA should be borne in mind when considering conditions responsible for the suppression of lymphocyte proliferation.
