  • 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.

  • Reversible posterior leukoencephalopathy syndrome (RPLS) is an acute encephalopathy, usually characterized by seizures, visual disorder, mental change and reversible posterior white and gray matter lesions on brain magnetic resonance imaging (MRI). Conditions commonly associated with RPLS include acute renal failure, eclampsia, hypertension, immunosuppresion state, and use of intravenous immunoglobulin or chemotherapy, and additional contributing factors. We report the case of RPLS associated with cyclosporine use in lupus nephritis. In this case, it was not clearly elucidated which was main cause of RPLS. We could think RPLS developed maybe due to combined effect of cyclosporine and lupus nephritis.

  • An 11-year-old, spayed female poodle presented with fever and shifting lameness. Physical examination revealed hyperthermia ($40.6^{\circ}C$), and proteinuria was detected upon urinalysis. Increased neutrophils (83%) and decreased viscosity were revealed upon synovial fluid analysis. Serum antinuclear antibody was positive at 1 : 80. Based on these findings, the dog was diagnosed with systemic lupus erythematosus. Immunosuppressive therapy was initiated with prednisolone and cyclosporine, and the condition was markedly improved after the treatments. This case report describes the clinical and laboratory findings, imaging characteristics and successful outcomes after prednisolone plus cyclosporine therapy in a canine systemic lupus erythematosus case.

  • After observing a patient diagnosed with Systemic Lupus Erythematosus from the September 21, 2000 to the January 13, 2001, the following results are obtained. Method and Result: We treated one case of Systemic Lupus Erythematosus with the Korean Bee Venom Therapy and the other Oriental Medical treatments. In acupuncture therapy, Korean Bee-venom Therapy is believed to be outstanding way to treat Systemic Lupus Erythematosus. Korean Bee Venom Therapy is treated on the following acupuncture points: ST36(B23(Shinsu:腎兪), BL26(Guanyuanshu:關元兪), ST36(Chok-Samni:足三里), LI4(Hapkok:合谷), LV3(Taechung), SP10(Hyolhae:血海) SP6 (Samumgyo;三陰交). In addition, CFC(Carthami Flos;紅花 and Cervi Pantotrichum Cornu;) Herbal-Acupuncture was applied on the acupucture points of GB20(Pungji: 風池), GB21(Kyonjong:), as well as BUM(It was made of Boviscalculus(牛黃), Moschus and Fel ursi Herbal-Acupuncture was given on CV17(Chonjung). In herbal medication, based on the Sasang Constitution, Taeyumin Chungsimyunja-Tang was given to the patient. As the results of these treatments, general conditions of this patient improved drastically. Conclusion: Based on the clinical results, traditional Korean Medical treatment is believed to be effective for treating Systemic Lupus Erythematosus, and futher studies should be carried out to provide more valuable information.

  • Purpose: The purpose of this study was to evaluate the prevalence, clinical characteristics, and long-term clinical effects of hypertension in Korean childhood-onset systemic lupus erythematous (SLE) patients. Methods: The medical records of SLE patients, diagnosed by 2019 SLE European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria, who visited Samsung Medical Center from January 2009 to May 2019 were reviewed. Disease activity and long-term damage were evaluated using the Modified Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and the Pediatric Systemic Lupus International Collaborating Clinics/ACR Damage Index (Ped-SDI), respectively. The sex-, age- and height-blood pressure standards recommended by the American Academy of Pediatrics 2017 guideline was used to define hypertension. Results: A total of 32 patients were enrolled in this study. The median follow-up duration was 7.3 years and females were predominant. The median ages at SLE and hypertension diagnoses were 14.2 and 14.3 years, respectively. The biopsy-proven lupus nephritis was detected in 90.6% and 37.5% were class IV. During the follow-up, 12 patients (37.5%) had hypertension. Among them, 2 patients had 3 episodes of posterior reversible encephalopathy syndrome and 5 patients had left ventricular hypertrophy (LVH). Univariate analysis showed baseline hypertension was significantly correlated with a lower estimated glomerular filtration rate, higher body mass index and SLEDAI at baseline. The development of hypertension during the follow-up was significantly correlated with obesity, LVH, and higher Ped-SDI. Conclusion: Our study revealed that hypertension in pediatric SLE is associated with obesity and renal function at SLE diagnosis and could affect long-term damage.

  • Brain meningioma, the most common benign brain tumor, has been reported to account for 13-26% of all intracranial tumors, with a crude incidence rate of 2.3 per 100,000 persons for all types of meningiomas. The prevalence of neuropsychiatric lupus erythematosus is 15-91% and its clinical manifestations are diverse: from mild cognitive dysfunction to serious neurological or psychiatric symptoms. Here, we report the first Korean patient with brain meningioma and systemic lupus erythematosus who had undergone surgical tumor resection.
