Objective〓〖WTBZ〗To observe the clinical features of autoimmune optic neuropathy (AON). 〖WTHZ〗Methods〓 〖WTBZ〗The clinical data of 58 patients with AON from Jan. 2006 to Dec. 2007 were retrospectively analyzed. The patients had undergone routine ophthalmological, neurological examination, visual field test, all set of autoimmune antibody test, brain MRI. 〖WTHZ〗Results〓〖WTBZ〗In 93 eyes of 58 patients with AON, the lowest best corrected visual acuity (BCVA) was lt;01 in 68 eyes (731%), 10 patients (172%) had other symptoms of nervous system, 14 patients (241%) had lesions of nonneurological system. Positive antinuclear antibody was found in 43 patients (796%); other abnormal antibodies were also found, including antiSSA/SSB, antidsDNA, antihistonic, anticardiolipin, and antihuman leukocyte antigen B27 antibodies. Systematic connective tissue disease presented in 20 patients (345%), such as sicca syndrome, systemic lupus erythematosus, and Behcet disease. 32 patients (552%) had abnormal brain MRI, and the BCVA of 49 eyes (777%) improved significantly after hospitalization. 〖WTHZ〗Conclusion〓〖WTBZ〗Patients with AON always have poor visual function, some of whom associate with other systems, as well as damages to other parts of the nervous system. While some AON patients are secondary to systemic connective tissue disease involving the optic nerve, the majority of these patients are isolated autoimmune optic neuropathy.
Iron death is an alternative to normal cell death and is regulated by a variety of cellular metabolic pathways. Iron death has become a hot topic of research because it can cause damage to various organs and degenerative diseases in the body. Metabolism, signalling pathways, endoplasmic reticulum stress, and immune cells can all affect the occurrence of iron death, and the blood-retina destruction induced by iron death plays an important role in autoimmune uveitis. Exploring the components of the blood-retina regulatory mechanism of iron death in autoimmune uveitis can lead to the search for targeted drug targets, which can provide a new research idea for the subsequent study of the diagnosis and treatment of autoimmune uveitis.
Neuromyelitis optica spectrum disorders (NMOSDs) are a class of immune-mediated inflammatory demyelinating diseases of the central nervous system that mainly involve the optic nerve and spinal cord. As an important environmental factor, the gut microbiota may play an important role in the occurrence and development of NMOSDs. Previous studies have shown that the structure and number of intestinal flora in NMOSDs patients are different from those of normal healthy people. The altered intestinal flora may cross-react with central nervous system autoantigens, induce T cell differentiation, and affect short-chain fatty acids, etc. The metabolite secretion pathway triggers the occurrence of NMOSDs. The summary of the changes of gut microbiota in patients with NMOSDs and the possible underlying mechanisms by summarizing the literature, aim to provide more effective treatments for the prevention and treatment of NMOSDs in the future.
ObjectiveTo explore the epidemiological and clinical features of hepatic hemangioma. MethodsThe clinical data of patients with hepatic hemangioma who were diagnosed in the First Affiliated Hospital of Guangxi Medical University from 2003 to 2011 were retrospectively analyzed, and then analyzed the epidemiological and clinical characteristics of hepatic hemangioma. ResultsEight hundreds and eighteen patients with hepatic hemangioma were included in the study.Among them, 398 cases (48.7%) were male, 420 cases (51.3%) were female, and there were no significant differences in constitute of gender for each year (χ2=9.912, P=0.271), but there were significant differences in constitute of gender between different age groups (χ2=18.791, P=0.000 1), male patients were more than female in the group of aged over 60 years old.There was no special clinical manifestations of hepatic hemangioma.There were 75 patients (9.2%) combined autoimmune diseases in this group.The size of hepatic hemangioma ranged from 0.5-39.0 cm, the median diameter was 3.0 cm.There were significant differences between different gender, the tumor size of female patients were larger than male's (P < 0.05).The tumor happened mostly in the right hepatic lobe (57.2%), and there were no significant differences of the tumor location in different gender (P > 0.05).Hepatic hemangioma with a single lesion was most common (70.0%), and the right lobe lesions were more common than the left lobe lesions in single lesion group, multiple lesions in double lobes were most common in multiple lesion group. ConclusionsHepatic hemangioma has a certain distribution pattern in gender, age, size, position, and so on, further research in prevention and controlled strategy need to be carried out in the future.At the same time, more in-depth research in the related factors participated in occurrence and development of hepatic hemangioma also need to be carried out, especially for the relationship between gender, age, autoimmune diseases, and hepatic hemangioma, which is worthy to be discussed.
The pathogenesis of Vogt-Koyanagi Harada disease (VKH) has not yet been fully defined. Current studies mainly suggest that VKH is actually an autoimmune disease, especially related to the immune response mediated by various signal transduction pathways involved in the function of T cells. In recent years, the influence of the balance imbalance of various T cell subsets in cellular immunity on the pathogenesis of VKH has been a hot research direction. Currently, T helper cell 17/T regulatory cells, balance is the focus of clinical research, meanwhile, new discoveries and potential clinical treatment schemes have been made for related cellular pathways, particularly the Janus kinase/signal transducers and activators of transcription pathway and NF-kappa B pathway. The exploration of B cells in the pathogenesis of VKH has also achieved initial results through the successful application of various targeted drugs. In the future, further screening and localization of genes or proteins that are abnormally regulated or expressed in VKH, for which early comprehensive and in-depth exploration will be helpful, thus improve the efficacy of clinical treatment programs and develop new therapeutic targets.
Autoimmune uveitis (AU) and mood disorders, such as anxiety and depression, share a close bidirectional association. Visual impairment caused by AU and the side effects of glucocorticoid therapy significantly increase the incidence of anxiety and depression. Conversely, mood disorders disrupt immune homeostasis through neuro-endocrine-immune mechanisms, exacerbating inflammatory responses and elevating the risk of AU recurrence. The primary reasons for AU-induced mood disorders include visual impairment, unpredictable fluctuations in vision, long-term treatment, and glucocorticoid-related psychiatric reactions. Meanwhile, mood disorders not only trigger the onset and recurrence of AU but also interfere with treatment efficacy by reducing patient adherence. The underlying mechanisms involve psychological stress leading to hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis, inflammatory factor-mediated “brain-eye axis” regulation, synergistic effects of the gut microbiota-brain-immune axis, and stage-specific immune regulatory characteristics of acute and chronic stress. Therefore, clinical management should emphasize the synergistic integration of psychological interventions and anti-inflammatory therapy to enable early detection and treatment of extramedullary lesions, optimize diagnostic and therapeutic protocols, and improve the prognosis of AU patients. Future research should further elucidate the molecular mechanisms underlying the interaction between mood and inflammation, establish multidisciplinary collaborative diagnosis and treatment systems, validate the efficacy of psychological interventions through large-scale clinical studies, and explore the development of neuroprotective anti-inflammatory drugs.
ObjectiveTo learn the distribution pattern and characteristics of autoimmune pancreatitis research literature, and its worldwide research trend. MethodsPublished data between September 22, 2004 and September 21, 2014 were searched by using the keyword autoimmune pancreatitis in the database of Pubmed. Publication year, journals, authors and research topics were bibliometrically analyzed. The analysis software Bibliographic Item Co-occurrence Matrix Builder was used for cluster analysis on high-frequency keywords. ResultsA total of 1 518 articles on autoimmune pancreatitis were acquired. The amount of published literature rose rapidly in the past 10 years, reaching its peak in the year of 2012. Most of the articles were published by several leading authors in the leading journals. There were 26 keywords with a frequency of more than 30 times, and 4 categories were classified through cluster analysis of these keywords. They were pathology and immunology, imaging, diagnosis and treatment. ConclusionsAttention on autoimmune pancreatitis has been increasing in the recent 10 years. Japanese researchers have been taking the lead. Current research focus is the diagnosis of autoimmune pancreatitis.
