Damage to bowel often complicates radiotherapy for abdominal and pelvic malignancy. The symptoms of chronic irradiation enteropathy, which often include intractable diarrhoea, are generally attributed to vascular injury. We have examined specimens of bowel resected from patients who had been therapeutically irradiated to assess the extent of injury to the enteric nerve plexuses. To facilitate visualisation of nerve fibres and cells of neural or neuroendocrine origin, sections were immunostained with antibodies to neuron-specific enolase or PGP 9.5, widely used markers of nerves and neurons. Electron microscopy was performed in selected cases. In 27 out of 33 specimens the number of nerve fibres in the lamina propria was obviously increased compared to that in control material. Scattered cells with the histological, immunohistochemical and ultrastructural features of ganglion cells were noted within the lamina propria in 23 of the specimens, and in 18 cases so-called neuroendocrine cells, not normally seen in this location, were also present. These radiation-induced changes in the innervation of the bowel may contribute to the symptoms of chronic radiation enteropathy.

Immunohistochemical examinations of the enteric nervous system (ENS) were performed on biopsies of healthy cats and compared to findings in cats suffering from inflammatory bowel disease or intestinal lymphoma. In lymphocytic-plasmacytic enterocolitis all affected samples had significant reductions in glial fibrillary acidic protein and vasoactive intestinal peptide (VIP) and mostly of neuron-specific enolase (NSE) possibly reflecting alterations in enteric glial cells and neurons. In cases with eosinophilic gastroenterocolitis significantly reduced phosphorylated neurofilament (PN) expression was present suggesting a disturbance in neuronal cytoskeleton, whereas cats with fibrosing enteropathy had reduced expression of NSE, non-phosphorylated neurofilaments (NPN), PN and VIP, possibly reflecting neuronal disturbances. In cases with intestinal lymphoma only the reduction in PN and the increase in NPN were obvious suggesting direct damage or interference of neoplastic cells with enteric neurons. In conclusion, structural and functional alterations of the ENS may contribute to clinically evident signs of vomiting and/or diarrhea.

INTRODUCTION Celiac disease (CD) is an immune-mediated enteropathy related to permanent gluten intolerance, characterized by gastrointestinal symptoms as well as nongastrointestinal symptoms, including neurologic ones. The presence of neuron-specific enolase (NSE), interleukin 10 (IL-10), and antiganglioside M1 (anti-GM1) antibodies has been demonstrated for neurologic conditions as well as immune disorders with neurologic manifestations. OBJECTIVES The aim of the study was to determine the concentrations of IL-10, NSE, and anti-GM1 antibodies in the course of CD and their correlation with changes in electrogastrography (EGG) and with heart rate variability (HRV). PATIENTS AND METHODS The study included 68 participants: 34 patients with CD and 34 healthy individuals. We assessed the concentrations of IL-10 and NSE as well as the presence of anti-GM1 antibodies in serum. We investigated correlations between the concentrations of IL-10, NSE, and anti-GM1 antibodies and the results of EGG and HRV. RESULTS Patients with CD had a higher level of anti-GM1 antibodies than controls (1.38 ng/ml [0.98-2.03 ng/ml] vs 0.81 ng/ml [0.35-1.15 ng/ml]). Median IL-10 concentrations in patients with CD differed significantly from those in controls (7 pg/ml [4.33-11.48 pg/ml] vs 4.27 pg/ml [2.44-7 pg/ml]; P = 0.010). In HRV analysis, a positive correlation between IL-10 concentrations and very low frequency spectrum was observed (r = 0.63; P = 0.003). There was no correlation between the concentrations of IL-10, NSE, or anti-GM1 antibodies and EGG parameters. CONCLUSIONS Chronic inflammation in the course of CD may lead to autonomic nervous system impairment and development of neurologic disorders. Therefore, anti-GM1 antibodies and IL-10 may be considered as markers of nervous system impairment in the course of CD.
