Clinical observations in chronic inflammatory diseases have demonstrated the significant influence of neuroendocrine mechanisms on the immune system: (1) Amelioration of rheumatoid arthritis during pregnancy; (2) preponderance of women versus men with respect to autoimmune diseases; (3) negative effects of ovulation-inducing therapy, oral contraceptives, and hormone replacement therapy; (4) protective effect of hemiplegia; (5) influence of psychological stress on inflammation; and (6) influence of circadian rhythms on inflammatory symptoms.The effects of different hormones and neurotransmitters on the immune system are influenced by: (1) the immune stimulus (foreign antigens or autoantigens) and subsequent antigen-specific immune responses, (2) the cell types involved during different phases of the disease, (3) the target organ with its specific microenvironment, (4) the timing of hormone or neurotransmitter increase in relation to the disease course, (5) the concentration of hormones and neurotransmitters, (6) the variability in expression of receptors depending on the microenvironment and the cell type, and (7) the intra- and extracellular peripheral metabolism of hormones and neurotransmitters leading to important biologically active metabolites with quite different anti- and proinflammatory functions.The circadian rhythm of disease-related symptoms with a peak in the early morning hours confirms that the neuroendocrine system has a strong influence on these chronic immune/inflammatory diseases. The influence is transmitted by the circadian fluctuation in the activity of hormonal and neuronal pathways linking the brain to immune cell activation.These considerations could lead to novel therapeutic strategies for rheumatic diseases in the future.

Rapid-onset dystonia-parkinsonism (RDP) is a movement disorder associated with mutations in the ATP1A3 gene. Signs and symptoms of RDP commonly occur in adolescence or early adulthood and can be triggered by physical or psychological stress. Mutations in ATP1A3 are also associated with alternating hemiplegia of childhood (AHC). The neuropathologic substrate of these conditions is unknown. The central nervous system of four siblings, three affected by RDP and one asymptomatic, all carrying the I758S mutation in the ATP1A3 gene, was analyzed. This neuropathologic study is the first carried out in ATP1A3 mutation carriers, whether affected by RDP or AHC. Symptoms began in the third decade of life for two subjects and in the fifth for another. The present investigation aimed at identifying, in mutation carriers, anatomical areas potentially affected and contributing to RDP pathogenesis. Comorbid conditions, including cerebrovascular disease and Alzheimer disease, were evident in all subjects. We evaluated areas that may be relevant to RDP separately from those affected by the comorbid conditions. Anatomical areas identified as potential targets of I758S mutation were globus pallidus, subthalamic nucleus, red nucleus, inferior olivary nucleus, cerebellar Purkinje and granule cell layers, and dentate nucleus. Involvement of subcortical white matter tracts was also evident. Furthermore, in the spinal cord, a loss of dorsal column fibers was noted. This study has identified RDP-associated pathology in neuronal populations, which are part of complex motor and sensory loops. Their involvement would cause an interruption of cerebral and cerebellar connections which are essential for maintenance of motor control.

Stroke research and rehabilitation have traditionally focused on the physical and functional impact of a stroke. Less attention has been given to the psychosocial factors associated with this chronic condition. By the few studies that have specifically focused on psychosocial factors in the context of stroke, poststroke depression is demonstrated to significantly influence stroke outcomes. Associations of stroke with psychological symptoms other than depression have rarely been evaluated. This study was aimed to investigate the changes of psychological stress, social support and medication adherence in patients with ischemic stroke in the mainland of China. In this study, 90 patients with hemiplegia one year after first-ever middle cerebral artery infarction (stroke group) in the Zhongnan Hospital of Wuhan University from June 2008 to June 2011 were recruited for interview. Ninety age- and sex-matched normal volunteers (control group) were also examined at the same period. The psychological distress was assessed by the Symptom Checklist 90 (SCL-90), the social support by the Social Support Rating Scale (SSRS), and medication adherence by Morisky's self-reported inventory, respectively. Group differences were analyzed using unpaired-t test and chi-squared test. The results showed that total mean scores of the SCL-90 in the stroke group were higher than those in the control group (P<0.01). Except two dimensions, paranoid ideation and psychoticism, mean scores of the rest dimensions (including somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, and phobic anxiety) of SCL-90 were significantly higher in the stroke group than those in the control group (P<0.05, or P<0.01). The objective support, subjective support, support availability and total social support scores in the stroke group were significantly higher than those in the control group (P<0.05, or P<0.01). Those in the "SCL-90 total scores >150 group" were significantly higher than in the "SCL-90 total scores <100 group" and the "SCL-90 total scores between 100 to 150 group" (P<0.05, or P<0.01). Those in the "SCL-90 total scores between 100 to 150 group" were significantly higher than in the "SCL-90 total scores <100 group" (P<0.05). In 90 patients with ischemic stroke, 26 (28.89%) patients obtained high medication adherence, 47 (52.22%) patients medium medication adherence, and 17 (18.89%) patients low medication adherence, respectively. Among these stroke patients, there were 17 (50.00%) patients with high medication adherence in the "SCL-90 total scores >150 group", 28 (75.67%) patients with medium medication adherence in the "SCL-90 total scores between 100 to 150 group", and 12 (61.16%) patients with low medication adherence in the "SCL-90 total scores <100 group", respectively. There was significant difference in the medication adherence rate among the different SCL-90 scores groups in these stroke patients (P<0.05 or P<0.01). It was led to conclude that ischemic stroke patients one year after hemiplegia have psychological distress, low level of social support and poor medication adherence in the mainland of China. Therefore, it is necessary to mobilize the government, medical institutions and various social support groups to offer psychological interventions to relieve the stress of patients with ischemic stroke, and improve their medication adherence.
