  • Systemic lupus erythematosus in a dog, suspected systemic lupus erythematosus in a dog, and autoimmune thrombocytopenic purpura hemmorrhagica in a dog are reported. A fice-year old, female Chihuahua (Case 1) showed initially hemorrhagic diathesis and purpura hemorrhagica. Afterward, it showed polymyositis and polyarthritis. LE-cell was demonstrated on LE-cell preparation trom blood. Systemic lupus erythematosus was diagnosed. This reponded well to the immunosuppressants, but developed iatrogenic Cushing syndrome and steroid hepatopathy. A two-and-half-year old, male toy poodle (Case 2) had chief complaint of red urine. Occult blood test for the urine sediment. This did not respond at all to antibiotics and carbazochrome, which is one of systemic coagulants. LE-cell was demonstrated on LE-cell preparation from blood. This responded relatively well to immunosupressants such as prenisolone, azathioprine and cyclophosphamide. systemic lupus erythematosus is suspected. A nine-year-and-three-month old, female Maltese (Case 3), which had history of congestive heart failure and ovariohysterectomy showed purpura hemorrhagica in the skin of chest. This had severe thrombocytopenia and leukocytosis. As prednisolone was administered before immunological examination or demonstration of LE-cell, it was impossible to diagnose whether purpura hemorrhagica developed as a member of systemic lupus erythematosus or independent of systemic lupus erythematosus. This responded well to prednisolone, and so autoimmune thrombocytopenic purpura hemorrhagica was diagnosed.

  • Vitiligo is a multifactorial disorder. Neural, biochemical, and autoimmune mechanisms have been hypothetically suggested as etiopathological contributors to this condition. Autoimmunity focuses primarily on genetic factors and the association between vitiligo and other autoimmune disorders including autoimmune thyroid disease, rheumatoid arthritis, psoriasis, type 1 diabetes, pernicious anemia, and Addison's disease. We describe a 35-year-old man with systemic lupus erythematosus who developed concurrent vitiligo and discoid lupus erythematosus suggesting the possible autoimmune association between these 2 different diseases.

  • Macrophage activation syndrome (MAS) is a potentially life-threatening complication in many autoimmune diseases. Early recognition and intervention are essential for a favorable outcome. Neonatal lupus, an acquired autoimmune disease in neonates caused by the transplacental passage of maternal autoantibodies, is rare and usually self-limited. Herein, we report a case of MAS in a patient with neonatal lupus, which improved with intravenous immunoglobulin.

  • Visceral leishmaniasis (VL) is a life-threatening infection caused by Leishmania species. In addition to typical clinical findings as fever, hepatosplenomegaly, and cachexia, VL is associated with autoimmune phenomena. To date, VL mimicking or exacerbating various autoimmune diseases have been described, including systemic lupus erythematosus (SLE), rheumatoid arthritis, and autoimmune hepatitis (AIH). Herein, we presented a patient with VL who had overlapping clinical features with SLE, AIH, as well as antimitochondrial antibody (AMA-M2) positive primary biliary cirrhosis.

  • Systemic Lupus Erythematosus(SLE) is an autoimmune disease invading the skin, joint, kidney, intestinal membrane, neurosystem and other organs. SLE is an autoimmune disease characterized by immune dysregulation resulting in the production of antinuclear antibodies(ANA), generation of circulating immune complexes, and activation of the complement system. In Korean medicine, lupus can be classified as acute arthritis, reddish butterfly erythema, asthenic disease, edema and so on. The cause and procedure of the diseases are flourishing noxious heat, excessive fire due to deficiency of yin, blood stasis due to stagnation of qi, internal movement of the liver-wind, congenital deficiency, exhausted vital-qi, which are treated by clearing away heat and cooling the blood, nourshing yin and extinguishing fire, treating flatulence and activating blood circulation, nourishing the blood to expel wind, invigorating the liver and kidney, invigorating qi and replenishing the blood. To experimentally examine the influence of Insam-Buja-Tang (Ginseng & Aconiti Extract, IBT) on the outbreak and development of lupus, lupus induce MRL/MpJ-Faslpr lupus-prone mice model was used. As IBT was orally administrated to a lupus model mouse, various tests such as the weight, urine protein, renal function, Lymph cell test of the spleen, Cytokine expression, histopathological analysis of kideny were performed to see the influence on the kidney and whether it work effectively on the immune function. The main purpose of this study is to evaluate the effect of IBT on MRL/MpJ-Faslpr lupus-prone mice model. The effect of IBT on MRL/MpJ-Faslpr lupus-prone mice that can have autoimmune disease similar to SLE in human was evaluated after IBT per oral in the present study.

  • Sj$\"{o}$gren's syndrome (SS) is an autoimmune disorder that affects the salivary glands, leading to xerostomia, and the lacrimal glands, resulting in xerophthalmia. Secondary SS is associated with other autoimmune disorders such as systemic rheumatic diseases and systemic lupus erythematosis (SLE), which can affect multiple organs, including the epidermis. Recent studies have demonstrated that green tea polyphenols (GTPs) possess both anti-inflammatory and anti-apoptotic properties in normal human cells. Epidemiological evidence has indicated that, in comparison to the United States, the incidence of SS, clinical xerostomia and lupus is considerably lower in China and Japan, the two leading green tea-consuming countries. Thus, GTPs might be responsible, in part, for geographical differences in the incidence of xerostomia by reducing the initiation or severity of SS and lupus. Consistent with this, molecular, cellular and animal studies indicate that GTPs could provide protective effects against autoimmune reactions in salivary glands and skin. Therefore, salivary tissues and epidermal keratinocytes could be primary targets for novel therapies using GTPs. This review article evaluates the currently available research data on GTPs, focusing on their potential application in the treatment of the oral manifestations of SS and skin manifestations of SLE.

  • Fresh Rehmanniae radix is known as a traditional medicine with anti-inflammatory and antioxidant activities. However, whether Rehmanniae radix attenuates autoimmune inflammation in lupus models characterized by T cell-dependent autoimmune disease including overproduction of proinflammatory cytokines, loss of T cell tolerance, and B cell hyperactivity remains unclear. We investigated the effect of fresh Rehmanniae radix methanol extracts (RGMeOH) on the in vitro overproduction of proinflammatory cytokines by immune cells from pristaneinduced lupus BALB/c mice. These results showed that RGMeOH remarkably attenuated Con A-increased overproduction of proinflammatory cytokines, such as IL-2, IFN-${\gamma}$, IL-6 and IL-10 by splenocytes from pristaneinduced lupus mice. RGMeOH greatly reduced LPS-induced production of TNF-${\alpha}$ by splenic macrophages from pristane-induced lupus mice, while significantly enhanced LPS-induced production of IL-10 but did not alter IL-6 by splenic macrophages and splenocytes. These findings suggest that RGMeOH may ameliorate lupus systemic inflammatory autoimmunity via down-regulation of TNF-${\alpha}$ and T cell-dependent cytokine production.

  • Systemic lupus erythematosus is a severe cutaneous-systemic disorder of unknown etiology, It is represented with erythematous patches on the face in a so-called butterfly distribution, and characteristically classified as an autoimmune disease with antinuclear antibodies. The autoimmune diseases such as systemic lupus erythematosus, $Sj{\ddot{o}}gren$ syndrome, rheumatoid arthritis have been associated with lymphoid malignancy - leukemia, malignant lymphoma - which could involve various organs(spleen, liver, brain, mediastinal lymph node, supraclavicular lymph node, inguinal lymph node, cervical lymph node etc.). Many authors have studied about the association of systemic lupus erythematosus and malignant lymphoma, but exact etiology is still unknown. A common viral etioloty for systemic lupus erythematosus has been suggested since virus-like particles have been found in the glomerular endothelium of patients with systemic lupus erythematosus. These oncogenic viruses may be responsible for the higher frequency of malignant lymphoma in patients with systemic lupus erythematosus. In the other theory, the causes of malignant lymphoma are the defect of immune system due to systemic lupus erythematosus and the long-term use of therapeutics for treatment of systemic lupus erythematosus. When the cellular immune system(delayed hypersensitivity) is impaired by immunosuppressive drugs, it is likely that the body is no longer able to recognize and reject malignant cells as they arise; they continue to grow and divide unhindered. The impairment of the cellular immune system may allow growth of oncogenic virus or the survival of neoplatic tissues. 47-year old female patient treated systemic lupus erythematosus with steroid and immunosuppressive drugs for 5 years visited to our hospital due to elevated mass on left upper anterior maxilla area. By performing biopsy, we diagnosed this lesion as malignant lymphoma and referred to oncologist for chemotherapy. So we report a case of malignant lymphoma due to systemic lupus erythematosus with review of literatures.

  • Systemic lupus erythematosus (SLE) is the prototypic systemic autoimmune disease characterized by production of autoantibodies to various nuclear antigens and overexpression of genes regulated by IFN-I called IFN signature. Genetic studies on SLE patients and mutational analyses of mouse models demonstrate crucial roles of nucleic acid (NA) sensors in development of SLE. Although NA sensors are involved in induction of antimicrobial immune responses by recognizing microbial NAs, recognition of self NAs by NA sensors induces production of autoantibodies to NAs in B cells and production of IFN-I in plasmacytoid dendritic cells. Among various NA sensors, the endosomal RNA sensor TLR7 plays an essential role in development of SLE at least in mouse models. CD72 is an inhibitory B cell co-receptor containing an immunoreceptor tyrosine-based inhibition motif (ITIM) in the cytoplasmic region and a C-type lectin like-domain (CTLD) in the extracellular region. CD72 is known to regulate development of SLE because CD72 polymorphisms associate with SLE in both human and mice and CD72-/- mice develop relatively severe lupus-like disease. CD72 specifically recognizes the RNA-containing endogenous TLR7 ligand Sm/RNP by its extracellular CTLD, and inhibits B cell responses to Sm/RNP by ITIM-mediated signal inhibition. These findings indicate that CD72 inhibits development of SLE by suppressing TLR7-dependent B cell response to self NAs. CD72 is thus involved in discrimination of self-NAs from microbial NAs by specifically suppressing autoimmune responses to self-NAs.

  • Idiopathic thrombocytopenic purpura(ITP) is characterized by the development of a specific anti-platelet autoantibody immune response mediating the development of thrombocytopenia. Systemic lupus erythematosus(SLE) is an autoimmune disease characterized by the production of a wide variety of autoantibodies. We experienced SLE patient whose initial symptoms were related to idiopathic thrombocytopenic purpura(ITP). She has a thrombocytopenia after Splenectomy and Steroid therapy on ITP and SLE. After she took Eight constitution Acupuncture treatment, thrombocytopenia has improved. We think Acupuncture will be effective treatment at autoimmune disease.
