The novel satiety factor nesfatin-1 has been shown to decrease food intake and body weight in rodents after i.c.v. injection. However, no further developments regarding the true patho-physiological relevance of nesfatin-1 in obesity and type 1 diabetes mellitus (T1 DM) and type 2 diabetes mellitus (T2 DM) have been reported. A recent study by Stengel et al. demonstrated that a down-regulation of NUCB2 mRNA in gastric endocrine cells was observed after 24-h fasting. They raised the possibility that nesfatin/NUCB2 gene expression may be regulated by nutritional status, suggesting that nesfatin-1 in the stomach might play a role in satiety. In the present study, fasting levels in plasma nesfatin-1, insulin and glucose were measured and analyzed in healthy subjects and in patients with T1 DM and T2 DM. Plasma nesfatin-1 levels were measured 6 times before and after oral glucose ingestion in healthy subjects. No sex differences in plasma nesfatin-1 were found. The mean fasting plasma nesfatin-1 levels were slightly but not significantly higher in T1 DM patients compared to healthy subjects. However, fasting plasma nesfatin-1 levels were significantly lower in T2 DM patients compared to healthy subjects and T1 DM patients. Plasma nesfatin-1 did not change acutely, although a small rise in circulating nesfatin-1 occurred within 30 min after the beginning of an oral glucose ingestion (from a mean basal value of 0.99+/-0.23 ng/ml to a maximum of 1.08+/-0.24 ng/ml). No significant difference in plasma nesfatin-1 before and after an oral glucose was observed. In conclusion, we showed that fasting nesfatin-1 was significantly lower in T2 DM patients compared to healthy subjects and T1 DM patients. The significance of this result is unclear but the reduction in fasting nesfatin-1 may be one of the appetite-related hormones involved in diabetic hyperphagia. In addition, neither glucose nor saline ingestions affected plasma nesfatin-1, suggesting that gastric chemosensation is not sufficient for the nesfatin-1 response under the present conditions.
