  • Lupus-like syndrome is characterized by multiple organ injuries including lungs and kidneys. Endotoxin induces a transiently intent systemic inflammatory response and indirectly transient acute lung injury in normal condition. However, whether endotoxin may trigger the persistent development of lung injury in chronic, inflammatory lupus-like syndrome compared with normal condition remains unclear. We examined the pulmonary vascular permeability and production of proinflammatory cytokines, such as TNF-${\alpha}$, IL-6, IL-10 and IFN-${\gamma}$, which play prominent roles in the pathogenesis of lupus-like tissue injury, 6 hand 72 h after i.p. lipopolysaccharide (LPS; endotoxin) injection in pristane-primed chronic inflammation ICR mice characterized by a lupus-like syndrome. These results demonstrated that levels of serum IL-6, IL-10 and IFN-${\gamma}$ and bronchoalveolar lavage (BAL) IL-6 and IFN-${\gamma}$ were remarkably increased 6 h in LPS-exposed pristane-primed mice compared with pristane-primed controls, while pulmonary vascular permeability and levels of serum and BAL TNF-${\alpha}$ were not. And levels of BAL TNF-${\alpha}$, IL-6 and IL-10 were significantly enhanced 72 h in LPS-exposed pristane-primed mice compared with pristane-primed controls. Also, LPS significantly induced the increased in vitro production of TNF-${\alpha}$, IL-6 and IL-10 by lung cells obtained from LPS-exposed pristane-primed mice compared with LPS-exposed normal mice. Our findings indicate that LPS may trigger persistent progression of lung injury through late overproduction of BAL TNF-${\alpha}$, IL-6, and IL-10 in lupuslike chronic inflammation syndrome compared with normal condition.

  • Purpose: The purpose of this study was to determine the mediating effects of self-efficacy and the belief about medication on the association between depression and medication adherence in patients with systemic lupus erythematosus. Methods: 128 patients aged ${\geq}19years$, who were regular outpatients or admitted patients diagnosed with systemic lupus erythematosus at a tertiary hospital in B city, participated in this study. Data were collected by using a self-administered questionnaire. Testing of mediating effects was analyzed by a parallel redundant mediated model using the PROCESS macro for SPSS version 3.3. Results: They scored an average of $16.71{\pm}11.13$ for depression, $694.14{\pm}170.68$ for self-efficacy, $3.05{\pm}4.60$ for the belief about medication, and $90.14{\pm}15.37$ for medication adherence. The direct effect of depression on medication adherence was not statistically significant, but the indirect effects of depression mediated with self-efficacy and belief about medication were statistically significant. Conclusion: It is necessary to develop and apply a nursing intervention program that can not only relieve depression but also promote self-efficacy and the belief about medication with the objective of improving medication adherence among patients with systemic lupus erythematosus.

  • Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disorder that affects mainly salivary and lacrimal glands, but its cause remains largely unknown. Clinical data indicating that SS occurs in a substantial proportion of patients with lupus points to common pathogenic mechanisms underlying the two diseases. To address this idea, we asked whether SS develops in the lupus-prone mouse strain sanroque (SAN). Owing to hyper-activation of follicular helper T (Tfh) cells, female SAN mice developed lupus-like symptoms at approximately 20 wk of age but there were no signs of SS at that time. However, symptoms typical of SS were evident at approximately 40 wk of age, as judged by reduced saliva flow rate, sialadenitis, and IgG deposits in the salivary glands. Increases in serum titers of SS-related autoantibodies and numbers of autoantibody-secreting cells in cervical lymph nodes (LNs) preceded the pathologic manifestations of SS and were accompanied by expansion of Tfh cells and their downstream effector cells. Thus, our results suggest that chronic dysregulation of Tfh cells in salivary gland-draining LNs is sufficient to drive the development of SS in lupus-prone mice.

  • Fluorouracil (FU) is well known to induce discoid lupus-like eruption at the sun exposure sites in Japan. It means the associations of UVB with drug induced DLE. It is still obscure which cytokines are involved in the development of DLE. To address the issue, we established a murine model of FU and UVB-induced discoid lupus and could show the Th1 dominant cytokine profiles in DLE model of TCR $\alpha$ chain KO mice treated with FU and UVB.

  • 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.

  • Systemic lupus erythematosus (SLE) is characterized by various symptoms and multi-organ involvement. Hypophosphatemia has been described in several diseases accompanied with systemic inflammation. However, hypophosphatemia has rarely been described in SLE patients, especially in those without nephritis. We report the case of a 13-year-old girl with SLE who developed hypophosphatemia without renal involvement. Her hypophosphatemia was caused by renal loss of phosphorus and persisted for 7 months. It improved as her complement levels increased. Therefore, hypophosphatemia may be related to disease activity in SLE patients.

  • 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.

  • The systemic lupus erythematosus(SLE) is a systemic inflammatory disease caused by autoimmune mechanism, involving blood cells, the kidney, the central nervous system, and etc. The heart is one of the frequently involved organs but it is rare as an initial manifestation. Therefore, early suspicion and accurate diagnosis followed by aggressive immunosuppressive therapy including corticosteroid is mandatory for heart-involved patients. We experienced a case of pericardial effusion as an initial manifestation of childhood SLE, which showed immediate response to corticosteroid.

  • Systemic lupus erythematosus is a disease of unknown etiology that affects many organ system and is characterized by the presence of multiple autoantibodies that participated in immunology mediated tissue injury. A 36 years-old female patient was admitted to ward due to high fever and erythematous rash on face and hole body. She exhibited itching sense, joint pain, nausea, fatigue, sensitivity to light. The homatologic finding revealed anemia, decrease of lymphocyte, low platelet count, but LE cell, Anti nuclear antibody(ANA) were negative. In the point of Differentiation of Syndrome(辨證), SLE can be thought to be a category of Seasonal febril disease(溫病). This subject diagnosed as Domination of intense evil heat(熱毒熾盛), and was administrated with Chungonpadocyem-gamibang(淸瘟敗毒飮加味方). The clinical and laboratory findings of our patient were improved by herb medication, acupuncture therapy and general supportive measure.

  • Left main coronary artery (LMCA) thrombosis is rare and the cause should be determined. A previously healthy young man presented with severe chest pain and dyspnea. The electrocardiogram showed typical ST-segment elevation myocardial infarction with clinical instability. Emergency coronary angiography revealed complete LMCA occlusion by thrombosis. After reperfusion, the patient was admitted to the cardiac care unit. He was diagnosed with hemolytic anemia and tested positive for antinuclear antibodies. Systemic lupus erythematosus (SLE) and LMCA disease due to systemic thrombosis were diagnosed. Steroids were started and the patient was discharged without complications. We report this rare case of LMCA thrombosis as an initial presentation of SLE.
