Objectives: Subjective life expectancy (SLE) has been found to show a significant association with mortality. In this study, we aimed to investigate the major factors affecting SLE. We also examined whether any differences existed between SLE and actuarial life expectancy (LE) in Korea. Methods: A cross-sectional survey of 1000 individuals in Korea aged 20-59 was conducted. Participants were asked about SLE via a self-reported questionnaire. LE from the National Health Insurance database in Korea was used to evaluate differences between SLE and actuarial LE. Age-adjusted least-squares means, correlations, and regression analyses were used to test the relationship of SLE with four categories of predictors: demographic factors, socioeconomic factors, health behaviors, and psychosocial factors. Results: Among the 1000 participants, women (mean SLE, 83.43 years; 95% confidence interval, 82.41 to 84.46 years; 48% of the total sample) had an expected LE 1.59 years longer than that of men. The socioeconomic factors of household income and housing arrangements were related to SLE. Among the health behaviors, smoking status, alcohol status, and physical activity were associated with SLE. Among the psychosocial factors, stress, self-rated health, and social connectedness were related to SLE. SLE had a positive correlation with actuarial estimates (r=0.61, p<0.001). Gender, household income, history of smoking, and distress were related to the presence of a gap between SLE and actuarial LE. Conclusions: Demographic factors, socioeconomic factors, health behaviors, and psychosocial factors showed significant associations with SLE, in the expected directions. Further studies are needed to determine the reasons for these results.

SLE 환자들에서 인지기능의 장애가 있는지를 알아보기 위해서 신경정신과적 병력이 없는 내과 외래 SLE 환자 20명과 정상 대조군 20명을 대상으로 전산화 신경인지기능 검사인 Vienna test system을 시행하고 이를 인지기능에 영향을 미칠 수 있는 임상 변인들과의 연관성을 분석하여 다음과 같은 결과를 얻었다. 1) SLE 환자군과 정상 대조군의 신경인지기능 검사의 각 항목 비교 인식력 검사항목에서 SLE 환자군은 정상 대조군에 비해 정확하게 응답한 반응수가 적었으며 '예'와 '아니오' 중 '아니오'를 정확하게 반응한 수도 적었다. 또한 '예'와 '아니오'에 대해 각각 정확한 반응을 하는 평균 반응시간이 길었으며 검사소요 시간도 길었다. 주의력 검사항목에서는 SLE 환자군이 정상 대조군에 비해 정확하게 응답한 반응수가 적었고, 평균 반응시간이 길었다. 그러나, corsi단기 기억력 검사항목에서는 시각적 단기 기억력 범위와 정확하게 맞춘 총 응답수에서 두군 간에 유의한 차이가 없었다. 표준도형 지능검사항목에서 SLE 환자군은 정상 대조군에 비해 정확하게 응답한 반응수가 적었다. 신경행동학적 인지상태 검사중 기억력 항목에서 SLE 환자군은 정상 대조군에 비해 유의하게 낮은 점수를 보였다. 2) 신경인지기능의 각 항목과 환자군의 연령, 교육연한, SLE 질환 활성도(SLE Disease Activity Index), 우울 증상의 정도, 항 ds-DNA항체. 보체 C3/C4, 스테로이드의 용량 등의 임상 변인들과의 상관관계를 비교하였을 때 통계적으로 유의하지 않았다. 이상의 결과에서 질환 활성도가 낮은 SLE환자들은 과거 신경정신과적 증상의 병력이 없고 병의 이환 기간이 비교적 짧음에도 불구하고 인지기능의 장애를 나타내었다. 그리고 이는 기타 장기의 침범으로 인한 비특이적 영향이 아닌 중추신경계의 침범에 의한 것으로 보이며 우울정도나 스테로이드 용량에 영향을 받지 않는 것으로 생각된다.

Background: Myasthenia gravis (MG) and systemic lupus erythematosus (SLE) are well recognized to coexist and have some similarities in immunologic, clinical and serologic findings. Despite several reports of the association with autoantibodies and thymectomy in these disorders, the pathomechanism of coexistence remains to be elucidated. Objective: We aimed to investigate the relationship of MG and SLE through overall features of patients with both disorders;: clinical, laboratory, and electrophysiological findings. Materials and Methods: We reviewed the medical records of 6 consecutive patients with MG and SLE (2 men, 4 women, ages 17-51, mean 30.5 years, Seoul National University Hospital, from 1998 to 2005). Results: Three patients who developed SLE first, had ocular type of MG and 2 were children showing much severe and recurrent SLE features and only 1 patient had thymic hyperplasia. The other 3 developed MG first and they were generalized type and none underwent thymectomy. In addition, the development of MG or SLE was not coincident with remission or improvement of another disorder. Conclusion: The coexistence of SLE and MG may support the hypothesis of two different antibody populations modulated by thymus in the opposite extremesThis report suggests that the systemic and extensive autoimmune response in preceding MG or SLE may effect the development of the other disorder followed, while. the coexistence of two disorders cannot be explained by the hypothesis of two different antibody populations modulated by thymus in the opposite extremes The role of thymectomy and the theorectical subsequent effect on the development of SLE have been debated with controversy. However, SLE occurred without thymectomy in MG and these disorders did not develop in the quiescent period of another disorder. Therefore, the other pathomechanism for the coexistence of MG and SLE should be elucidated.

Background: Immunoglobulin (Ig) light chain repertoire has been implicated as a critical determinant in regulation of autoreactive B cells and production of pathogenic anti-DNA antibodies in systemic lupus erythematosus (SLE). We analyzed the impact of Ig ${\lambda}$ chain repertoire on development of autoimmunity in patients with SLE. Methods: We obtained genomic DNA from individual peripheral CD19+ B cells of 3 untreated active SLE patients, and amplified $V{\lambda}$ rearrangements from each single cell by polymerase chain reaction. Results: A total number of 208 $V{\lambda}J{\lambda}$ rearrangements were analyzed. Analyzed sequences included 158 productive rearrangements and 50 nonproductive rearrangements. The differences in $V{\lambda}$ gene usage in the productive and nonproductive repertoire of SLE patients were found compared to the non-autoimmune individuals. $V{\lambda}$ gene, 9A was significantly overrepresented in nonproducative repertoire of SLE patients (P=0.016). In the productive repertoire, $V{\lambda}$ genes, 3L and 1E were found more often in the SLE patients (P=0.001, P=0.043). When the productive and the nonproductive repertoires were compared, 9A was found significantly less in the productive repertoire in the SLE patients (P=0.000). There were no significant differences in the $J{\lambda}$ gene usage between SLE patients and non-autoimmune individuals, but $J{\lambda}2/3$ gene was the most frequently used in SLE, whereas $J{\lambda}7$ gene was the most frequently used in the normal subjects. In the productive SLE $V{\lambda}$ repertoire, 9.4% of the total sequences employed identical CDR3. It was particularly striking to find 7 identical versions of the 1G-$J{\lambda}2/3$ $V{\lambda}J{\lambda}$ rearrangements from one patient and 3 of the same sequence from another patient. Notably, identical $V{\lambda}$ junctions in the SLE patients utilized significantly more homologous joining compared to $V{\lambda}$ junctions of the normal adults (P=0.044). Conclusion: These data demonstrate regulation of ${\lambda}$ light chain expression in the SLE patients by selection of unique $V{\lambda}$ genes. Also, biased selection and clonal expansion of particular $V{\lambda}$ rearrangements are apparent in the SLE ${\lambda}$ repertoire.

Systemic lupus erythematosus (SLE) is an inflammatory-autoimmune disease with a complex multi-organ pathogenesis, and it is known to be associated with significant morbidity and mortality. Various genetic, immunological, endocrine, and environmental factors contribute to SLE. Genomic variants have been identified as potential contributors to SLE susceptibility across multiple continents. However, the specific pathogenic variants that drive SLE remain largely undefined. In this study, we sought to identify these pathogenic variants across various continents using genomic and bioinformatic-based methodologies. We found that the variants rs35677470, rs34536443, rs17849502, and rs13306575 are likely damaging in SLE. Furthermore, these four variants appear to affect the gene expression of NCF2, TYK2, and DNASE1L3 in whole blood tissue. Our findings suggest that these genomic variants warrant further research for validation in functional studies and clinical trials involving SLE patients. We conclude that the integration of genomic and bioinformatic-based databases could enhance our understanding of disease susceptibility, including that of SLE.

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.

To find the cause, pathology, oriental presciptions for SLE(systemic lupus erythematous) in the field of oriental medicine, we studied the clinical reports. The results were obtained as follows: 1. SLE can' be thought to be a category of chronic fatigue, numbness, yang poison' & erythema. 2. The chief cause of SLE could be a febrile poison and the lack of physiological fluid and the mechanism was that febrile poison attacted area of circulation and blood and injuried the physiological fluid to arise edema and clotted blood. 3. The therapy of SLE was chiefly clarifying heat and toxiciding in acute stage while reinforcing kidney and liver and supplementing Yin & clarifying in chronic stage, sometimes supplementing Qi, eliminating clotted blood, excuding wind and draining water could be applied. 4. The therapy for SLE nephritis was shown to be increasing yin and clarifying heat with toxiciding, reinforcing spleen and kidney, draining water, supplementing yin & Qi etc. The chief prescriptions were Seogakjihwangtang(犀角地黃湯), Wookakjihwangtang(牛角地黃湯), yeechihwan(二至丸), Daepowonjeon(大補元煎), Daepoeumhwan(大補陰煎), Kikukjihwangtang(杞菊地黃湯), Yookmijihwangtang(六味地黃湯) which indicates Rhemanniae radix added prescrition could be used chiefly for the treatment of SLE.
