The ghrelin hormone is one of the major regulators of appetite. Objectives To evaluate appetite and ghrelin levels in patients with IDA, and to investigate the change in appetite and ghrelin following intravenous iron therapy. Methods A total of 56 IDA patients and 51 controls were included in the study. Both appetite and ghrelin were assessed at baseline and following intravenous iron therapy. These were assessed at corresponding time intervals in the control group. Appetite was assessed by the SNAQ score (Simplified Nutritional Appetite Questionnaire) and fasting ghrelin levels were assessed by acylated ghrelin (AG), unacylated ghrelin (UAG) and their respective ratio AG/UAG. Results IDA patients had significantly lower SNAQ scores, yet higher AG levels and higher AG/UAG ratios compared to healthy controls; the mean SNAQ scores were 12.56 ± 3.45 and 16.1 ± 2, respectively (P less then 0.01); the median AG levels were 57.5 pg/ml and 43 pg/ml respectively (P = 0.007); and the median AG/UAG ratios were 0.48 and 0.25 respectively (P = 0.04). On multivariate linear regression analysis, IDA remained independently associated with decreased SNAQ score (β = -0.524, P less then 0.001) and increased acylated ghrelin (β = 0.289, P = 0.013). After IDA was treated, SNAQ scores increased significantly by a mean of 2 points. AG and AG/UAG ratios decreased significantly by a mean of -18.44 pg/ml and -0.2 respectively. The control group showed no significant change in SNAQ scores or ghrelin at corresponding time intervals. Conclusions IDA patients have a reduced appetite and paradoxically elevated ghrelin hormone activity compared to healthy controls. Treating IDA enhances appetite and lowers ghrelin levels. Future studies are needed to explore the mechanism of this paradoxical ghrelin activity.The impact of a method for MR-based respiratory
