Secretin, a gastrointestinal (GI) peptide, may offer therapeutic benefit in autism. Autistic features can also be present in schizophrenia and a recent study suggested a role for adjunctive secretin in treatment-resistant schizophrenia. The current report describes one patient with undifferentiated schizophrenia and prominent autistic features who received a single dose of secretin and demonstrated substantial yet transient improvement. The case illustrates the potential role of secretin as a novel adjunctive treatment strategy in schizophrenic patients with autistic features.

Secretin shows a wide distribution in the brain. Functional significance of central secretin is stressed since it has been associated with autism and schizophrenia. The presence of the secretin receptor was previously demonstrated in the brain by different methods. Neurons in the cerebellum, hypothalamic paraventricular and supraoptic nuclei, and in the vascular organ of lamina terminalis were shown to express secretin receptor mRNA by using in situ hybridization with digoxigenin-labeled probe. In this work, we used a very sensitive radioactive in situ hybridization technique and systematically mapped the expression of secretin receptor mRNA in the brain. The densest labeling was observed in the nucleus of solitary tract and in the laterodorsal thalamic nucleus, where decreasing number of receptors was seen in the vascular organ of lamina terminalis, and the lateral habenular complex, and then in the supraoptic nucleus. Only a few scattered labeled cells were observed in the median frontal gyrus, entorhinal cortex, hypothalamic paraventricular nucleus, perifornical region, lateral hypothalamic area, head of the caudate nucleus, spinal trigeminal nucleus, and cerebellum. Secretin receptor mRNA showed a far wider distribution than was known before, suggesting a more significant functional relevance than thought earlier.
