Abstract
The aim of this study is to analyze whether clozapine serum concentration may affect fasting serum levels of several appetite regulating peptides: CART, PYY(1-36), NPY, AgRP, des-acylated ghrelin, leptin and obestatin. Serum concentration of clozapine and fasting serum levels of des-acylated ghrelin, neuropeptide Y (NPY), agouti-related protein (AgRP), peptide YY (PYY(1-36)), cocaine- and amphetamine-regulated transcript (CART), leptin and obestatin were measured in 30 subjects with schizophrenia on clozapine monotherapy. Leptin concentration was negatively correlated with clozapine dose (r = â0.53, p = 0.002), while NPY concentration was negatively correlated with clozapine concentration (r = â0.55, p = 0.01). Correlations with other peptides were not significant. We cannot conclude that serum concentration of clozapine is directly associated with increased or decreased level of appetite-regulating peptides.
