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.

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease that affects multiple organs. More than half of the patients with SLE have kidney involvement, and up to 10% of patients with lupus nephritis develop end-stage renal disease (ESRD). Central nervous system (CNS) involvement in SLE occurs in 21% to 95% of patients. Severe neurological manifestations such as seizures, cerebrovascular disease, meningitis, and cerebrovascular accidents can develop in childhood-onset SLE, but cerebral infections, such as brain abscess and hemorrhage, are seldom reported in lupus nephritis, even in adults. Here, we report a rare case of childhood-onset SLE with ESRD, cerebral abscess, and hemorrhage. A 9-year-old girl diagnosed with lupus nephritis was administered high-dose steroids and immunosuppressant therapy to treat acute kidney injury (AKI) and massive proteinuria. The AKI deteriorated, and after 3 months, she developed ESRD. She received hemodialysis three times a week along with daily peritoneal dialysis to control edema. She developed seizures, and imaging showed a brain abscess. This was complicated by spontaneous cerebral hemorrhage, and she became unstable. She died shortly after the hemorrhage was discovered. In conclusion, CNS complications should always be considered in clinical practice because they increase mortality, especially in those with risk factors for infection.

Systemic lupus erythematosus (SLE) is an episodic, multi-system, autoimmune disease characterized by widespread inflammation of blood vessels and connective tissues and by the presence of antinuclear antibodies (ANAs), especially antibodies to native (double-stranded) DNA (dsDNA). Its clinical manifestations are extremely variable, and its natural history is unpredictable. Untreated, SLE is often progressive and has a significant fatality rate. The most widely used criteria for the classification of SLE are those of the American College of Rheumatology (ACR), which were revised in 1982 and modified in 1997. The presence of four criteria have been diagnosed as a SLE. Rashes are common at onset and during active disease. The oral mucosa is the site of ulceration with SLE. Arthralgia and arthritis affect most children and these symptoms are short in duration and can be migratory. Lupus nephritis may be more frequent and of greater severity in children than in adults. The initial manifestation of nephritis is microscopic hematuria, followed by proteinuria. The most common neuropsychiatric symptoms are depression, psychosis(hallucination and paranoia) and headache. CNS disease is a major cause of morbidity and mortality. Pericarditis is the most common cardiac manifestation. Libman-Sacks endocarditis is less common in children. The most frequently described pleuropulmonary manifestations are pleural effusions, pleuritis, pneunonitis and pulmonary hemorrhage. During the active phase ESR, CRP, gamma globulin, ferritin and anti-dsDNA are elevated. Antibodies to dsDNA occur in children with active nephritis. Antibodies to the extractable nuclear antigens (Sm, Ro/SS-A, La/SS-B) are strongly associated with SLE. Specific treatment should be individualized and based on the severity of the disease. Sepsis has replaced renal failure as the most common cause of death.

In childhood systemic lupus erythematosus patients, renal involvement is closely related to mortality and morbidity of the disease. Therefore early diagnosis and treatment are essential to improving prognosis. We saw a child who had hematuria, albuminuria, anorexia, fatigue, and light hyper sensitiveness. He was diagnosed as lupus nephritis (WHO Class II+IV) and treated with ACE inhibitor and steroid therapy for 12 months. However, clinical improvement was not shown. So we treated him with herbal formula (Jasinwhalhyul-tang: Zishenhuoxue-tang) and steroid therapy. After 17 months of treatment, hematuria disappeared and clinical symptoms and albuminuria had improved significantly.

목 적 : 루프스 신염은 전신성 홍반성 낭창(systemiclupuserythematosus,SLE)의 가장 심각한 합병증 가운데 하나이지만, 소아 연령에서 루프스 신염에 대한 국내 연구는 미약한 실정이다. 본 연구는 루프스 신염 환자를 대상으로 빈도, 임상상, 치료반응, 예후 등에 대한 기초 조사를 실시하여 향후 전국 규모의 다기관 연구를 위한 기반 자료로 사용하기 위함이다. 방 법 : 1986년부터 1997년 11년 동안 서울대학교 어린이병원 소아과에 입원한 SLE환아 53례 중 신생검상 루프스 신염이 확인된 46례를 대상으로 후향적 의무기록 고찰을 시행하였다. 결 과 : 1) 전체 남녀비는 1:2.5, 루프스 신염의 진단 당시 정중연령은 12.8세(2세-15세 8개월)이었다. 2) ARA 분류 기준 중 형광항핵항체($85.7\%$), 항ds-DNA항체($78.0\%$), 나비모양 홍반($60.8\%$) 등이 가장 빈번히 관찰되었으며, 기타 검사 소견중에서는 C3의 감소($88.9\%$)가 흔하였다. 3) 혈뇨($87.0\%$)는 가장 흔한 신장 증상이었고, 신생검상 41례에서 WHO class IV 병변이 확인되었다. 4) Prednisolone, azathioprine, 경구 또는 정맥 cyclophosphamide 등을 단독 또는 병합치료 결과 대부분 환자에서 질환 활성도가 정상 혹은 중증도 이하로 조절되었으며, 치료 종류에 따른 반응도의 차이는 관찰할 수 없었다. 5) 감염은 치료 경과중 가장 흔한 합병증이었으며, 특히 Varicella-Zoster virus와 candida 감염증이 흔하였다. 결 론 : SLE 환아중 루프스 신염의 빈도는 $87.0\%$이었고, 그중 $89.1\%$가 장기적 예후가 불량한 WHO class IV 로 확인되었다. 따라서 신염 초기의 적극적인 면역억제제 사용이 장기적 예후 향상에 도움을 주리라 사료되며, 이에 대한 장기간의 전향적-비교연구를 위하여 다기관 공동연구가 절실히 필요하다.

Background: Deposition of immune complexes drives podocyte injury acting in the initial phase of lupus nephritis (LN), a process mediated by B cell involvement. Accordingly, targeting B cell subsets represents a potential therapeutic approach for LN. Ginsenoside compound K (CK), a bioavailable component of ginseng, possesses nephritis benefits in lupus-prone mice; however, the underlying mechanisms involving B cell subpopulations remain elusive. Methods: Female MRL/lpr mice were administered CK (40 mg/kg) intragastrically for 10 weeks, followed by measurements of anti-dsDNA antibodies, inflammatory chemokines, and metabolite profiles on renal samples. Podocyte function and ultrastructure were detected. Publicly available single-cell RNA sequencing data and flow cytometry analysis were employed to investigate B cell subpopulations. Metabolomics analysis was adopted. SIRT1 and AMPK expression were analyzed by immunoblotting and immunofluorescence assays. Results: CK reduced proteinuria and protected podocyte ultrastructure in MRL/lpr mice by suppressing circulating anti-dsDNA antibodies and mitigating systemic inflammation. It activated B cell-specific SIRT1 and AMPK with Rhamnose accumulation, hindering the conversion of renal B cells into plasma cells. This cascade facilitated the resolution of local renal inflammation. CK facilitated the clearance of deposited immune complexes, thus reinstating podocyte morphology and mobility by normalizing the expression of nephrin and SYNPO. Conclusions: Our study reveals the synergistic interplay between SIRT1 and AMPK, orchestrating the restoration of renal B cell subsets. This process effectively mitigates immune complex deposition and preserves podocyte function. Accordingly, CK emerges as a promising therapeutic agent, potentially alleviating the hyperactivity of renal B cell subsets during LN.

목적 : 전신성 홍반성 낭창(Systemic lupus erythematosus, SLE)은 여러장기를 침범하는 자가면역성 질환으로 신장의 손상이 본 질환의 예후를 좌우하는 주요원인이다. 특히 소아에서 루프스 신염은 성인보다 그 빈도가 높고, 증상이 심하므로, 신생검은 효과적인 치료의 계획을 위해서 중요한 수기이다. 이에 저자는 소아연령에서 루프스 신염의 임상적 병리학적 특성 및 치료방법에 대해 전반적으로 고찰하여 예후의 향상을 기대하고자 한다. 방법 : 1990년 1월부터 2002년 9월까지 소아과에서 전신성 홍반성 낭창으로 진단받은 63례의 환아중 신생검을 시행하여 루프스 신염으로 진단되었던 40례를 대상으로 의무 기록을 후향적으로 고찰하였다. 결과 : 환아의 남녀비는 1:3이었고 진단당시 평균발병 연령은 12.1(2-18)세였다. ARA 기준중에서는 형광 항핵항체(95.0%), 항dsDNA항체(87.5%), 나비모양 홍반(80.0%)의 순이었다. 가장 흔한 신장증상은 단백뇨와 현미경적 혈뇨(75.0%), 신증후군(55.0%), 현미경적 혈뇨 단독(15.0%)의 순이었고, 신생검상 27례(67.5%)에서 WHO Class IV 병변이 관찰되었고 3례에서 추적 관찰 신생검에서 조직소견이 바뀌었다. 치료는 prednisolone 단독 5례, prednisolone+azathioprine 9례, prednisolone+azathioprine+정맥cyclophosphamide 14례, prednisolone+cyclosporineA+정맥 cyclophosphamide 12례였고, 9례에서 혈장 교환술을 시행하였다. 환아들의 평균 추적관찰은 $51.8{\pm}40.5$개월이었고 사망은 4례에서 있었다. 사망과 관련된 위험인자로는 진단당시 성별이 남아일 때, WHO class IV의 조직소견, 급성 신부전을 동반할 때 의미있는 것으로 나타났다. 결론 : SLE 환아 중 루프스 신염의 빈도는 63.5%였으며 그중 67.5%가 예후가 불량한 WHO Class IV로 확인되었다. 따라서 신염의 초기에 적극적인 면역억제제 사용이 장기 예후 향상에 도움을 주리라고 생각된다. 하지만 소아기에 성장, 정신 사회적 발달, 생식기의 독성 등도 중요한 문제이므로 항상 적절한 치료를 위해 세심한 관심을 쏟아야 할 것이다.

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.
