  • Drug-induced autoimmune hepatitis (DIAIH) is an increasingly recognized form of drug-induced liver injury that leads to a condition similar to idiopathic autoimmune hepatitis. A number of drugs have been associated with DIAIH, minocycline is one of the most well characterized. Minocycline is a semisynthetic tetracycline antibiotic used in the treatment of acne vulgaris. Minocycline-induced autoimmune hepatitis presents with serologic and histologic features similar to idiopathic autoimmune hepatitis. However, the natural history and outcomes of these two conditions differ significantly. The majority of patients with minocycline-induced autoimmune hepatitis experience complete resolution of symptoms after withdrawal of the medication. Some patients may require a short course of steroids and rarely use of an immunomodulator to achieve resolution of disease. Recurrence of symptoms is rare and typically only occurs with reintroduction of minocycline. It is important for primary care providers to consider minocycline-induced autoimmune hepatitis when liver injury develops during minocycline therapy.

  • Kikuchi-Fujimoto disease (KFD) is a benign self-limiting disease characterized by fever and lymphadenitis. The etiology and pathogenesis of KFD is unclear. However, two hypotheses have been suggested: a viral infection hypothesis and an autoimmune hypothesis. Several KFD patients with various types of autoimmune diseases have been reported, and these reports support the hypothesis for autoimmune pathogenesis of KFD. Here, we report the case of a 17-year-old female patient diagnosed with KFD and autoimmune thyroiditis. This case serves as additional evidence that the etiology of KFD is autoimmune origin.

  • Autoimmune hemolytic anemia is a disease characterized with destruction of erythrocytes as a result of antibody produce against patient's own erythrocytes and anemia. Autoimmune hemolytic anemia can be roughly stratified into two groups according to serological features and secondary causes including drugs induced hemolytic anemia. Drugs induced autoimmune hemolytic anemia is very rare in pediatric patients. Even though hematological side effects such as leucopenia, agranulocytosis, eosinophilia, thrombocytopenic purpura and aplastic anemia might occur due to psychotropic drug use; to the best of our knowledge there is no autoimmune hemolytic anemia case due to quetiapine, an atypical antipsychotics, in literature. We hereby describe the first child case of autoimmune hemolytic anemia during quetiapine treatment.We also are pointing out that one should keep in mind serious hematological side effects with atypical antipsychotic drug use with this case report.

  • Objectives: It was aimed to investigate the basic action mechanism of the autoimmune diseases and common features of all diseases. Autoimmune disease are classified organ specific and systemic. Methods: These diseases are seen systemic and disease start locations, origins seem differently. This makes learning and understanding difficult. Autoimmune diseases investigated for easier understanding. It was noticed that, autoimmune diseases' starting places are specific and same all of them. This remarkable point is very important for acupuncture also. So; whole literatüre was researched and important point was found. Results: Whole autoimmune diseases are attack to mesodermal layers and mesodermal origin organs of the body's. The common property of all these disease are same; Diseases start from the mesoderm and mesodermal layer even though their organ origins' belongs to different germ layer. From this point of view, we were able to classify autoimmune diseases simply and it was planned how can we effect body in this context with acupuncture. Conclusion: And, when immunity comes into question, induction of adaptive immunity is depend on antigen presentation to T cells and this situation take place in the lymph node (LN) and also in the skin.When we sank the acupuncture needle into skin, signals create and start mesodermal contacts, during this time mesenchymal origin' autoimmune cells are regulated with this signals.

  • Autoimmune disease is known to be caused by unregulated self-antigen-specific T cells, causing tissue damage. Although antigen specificity is an important mechanism of the adaptive immune system, antigen non-related T cells have been found in the inflamed tissues in various conditions. Bystander T cell activation refers to the activation of T cells without antigen recognition. During an immune response to a pathogen, bystander activation of self-reactive T cells via inflammatory mediators such as cytokines can trigger autoimmune diseases. Other antigen-specific T cells can also be bystander-activated to induce innate immune response resulting in autoimmune disease pathogenesis along with self-antigen-specific T cells. In this review, we summarize previous studies investigating bystander activation of various T cell types (NKT, γδ T cells, MAIT cells, conventional CD4+, and CD8+ T cells) and discuss the role of innate-like T cell response in autoimmune diseases. In addition, we also review previous findings of bystander T cell function in infection and cancer. A better understanding of bystander-activated T cells versus antigen-stimulated T cells provides a novel insight to control autoimmune disease pathogenesis.

  • To verify the association between GSTM1/GSTT1 gene polymorphisms and susceptibility to autoimmune diseases in Asian population. 18 published reports cited in EMBASE, Google, KISS, MEDLINE and PubMed up to December 2015 were collected for a meta-analysis. The GSTM1/GSTT1 polymorphism for null and present type were analysed separately. The significant association was found between the GST polymorphism and autoimmune diseases in an overall population (GSTM1, OR=1.334, 95% CI=1.137-1.567, p=0.000; GSTT1, OR=1.212, 95% CI=1.012-1.452, p=0.037). Asian population showed the significant association of GSTM1 in the autoimmune diseases, especially vitiligo and atopic dermatitis but non-significant association of GSTT1 in RA and SLE. The GSTM1 null and the GSTT1 present type showed the association with autoimmune diseases in Asian population. The null type frequency of the combination of GSTM1-GSTT1 polymorphism in autoimmune diseases in Asian population was higher than that of the control group. This result indicated that null type of GSTM1-GSTT1 combination can be a risk factor of autoimmune diseases in Asian population.

  • Autoimmune enteropathy is a rare chronic diarrheal disease of infancy. Clinicopathologically, this entity is characterized by chronic secretory diarrhea, villous atrophy with crypt hypoplasia of a small intestine and/or associated autoimmune disorders, and absence of severe immunodeficiency. For the confirmation of diagnosis, antienterocyte autoantibody should be delineated. The treatment of choice of this disorder is immunosuppression. We has been experienced a case of autoimmune enteropathy without autoimmune disorders in a 10-month-old male infant. He developed protracted diarrhea from 5 months of his age and has been appeared to be failure to thrive. Antienterocyte autoantibody was demonstrated by immunohistochemistry and western blotting. He was successfully treated with corticosteroid and FK506. This is the first case report of autoimmune enteropathy without autoimmune disorders in Korea.

  • Autoimmune thyroiditis is the most common cause of hypothyroidism in the world. It is characterized clinically by gradual thyroid failure, goiter formation, or both, because of the autoimmune-mediated destruction of the thyroid gland. Renal involvement presenting proteinuria in autoimmune thyroiditis is not uncommon, occurring in 10% to 30% of the cases. Glomerulonephropathy associated with autoimmune thyroiditis, however, is a rare disease. Most reports of autoimmune thyroiditis with glomerulonephropathy have demonstrated a mixed pathological morphology and have been predominantly associated with membranous glomerulopathy. The case of minimal-change disease associated with thyroiditis presenting acute kidney injury is a rare disease that has not been reported in South Korea. Reported herein is the case of a 16-year-old man diagnosed with Hashimoto's thyroiditis, with minimal-change disease presenting acute kidney injury. He revealed hypothyroidism, proteinuria, and impaired renal function. Renal biopsy showed minimal-change disease and minimal tubular atrophy. The patient was treated with thyroid hormone, and his renal function and proteinuria improved. Therefore, for patients with autoimmune thyroiditis presenting unexplained proteinuria, glomer-ulonephropathy should be ruled out. Conversely, for patients with glomerulonephropathy and persistent proteinuria despite proper treatment, thyroid function and antibody tests should be performed.

  • There have been vast amount studies regarding immunologic dysregulation in schizophrenia. The mechanism of immune pathogenesis in schizophrenia still is unclear, even though various immune dysfunction have been reported. We endeavored to report on two major hypothesis on immunologic dysregulation in schizophrenia, the infection hypothesis and autoimmune hypothesis. We went on to focus on the autoimmune hypothesis, which has received the most attention over the years. We explored the accumulated data and the rational behind the autoimmune hypothesis and the implications of the autoimmune hypothesis for future research in the pathogenesis of schizophrenia.

  • Inflammasomes are intracellular multiprotein complexes that coordinate anti-pathogenic host defense during inflammatory responses in myeloid cells, especially macrophages. Inflammasome activation leads to activation of caspase-1, resulting in the induction of pyroptosis and the secretion of pro-inflammatory cytokines including interleukin $(IL)-1{\beta}$ and IL-18. Although the inflammatory response is an innate host defense mechanism, chronic inflammation is the main cause of rheumatic diseases, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), and $Sj{\ddot{o}}gren^{\prime}s$ syndrome (SS). Since rheumatic diseases are inflammatory/autoimmune disorders, it is reasonable to hypothesize that inflammasomes activated during the inflammatory response play a pivotal role in development and progression of these diseases. Indeed, previous studies have provided important observations that inflammasomes are actively involved in the pathogenesis of inflammatory/autoimmune rheumatic diseases. In this review, we summarize the current knowledge on several types of inflammasomes during macrophage-mediated inflammatory responses and discuss recent research regarding the role of inflammasomes in the pathogenesis of inflammatory/autoimmune rheumatic diseases. This avenue of research could provide new insights for the development of promising therapeutics to treat inflammatory/autoimmune rheumatic diseases.
