Pulmonary pathogenesis in lupus is characterized by interstitial inflammation and vasculitis in lungs. We investigated whether bamboo culm extract (BC) attenuates pulmonary inflammation and lung injury in pristane-induced lupus mice. The pristane-induced lupus mice and healthy mice were administrated with BC 0.5 ml/kg or PBS orally once a day for 14 days. Our results demonstrated that BC significantly attenuated levels of bronchoalveolar lavage (BAL) IL-6, IL-10, IFN-$\gamma$, $PGE_2$ and VEGF, and pulmonary vascular permeability in pristane-induced lupus mice. Therefore, these findings suggest that BC may inhibit development of pulmonary inflammation and lung injury in lupus.

Lupus thrombocytopenia is a common clinical manifestation in systemic lupus erythematosus (SLE). It may present to clinicians with considerable therapeutic difficulties. We experienced a 40-year-old poly trauma patient with lupus thrombocytopenia who had been treated with immunosuppressive drugs for SLE. She was treated for refractory thrombocytopenia with platelet transfusion, corticosteroid and Intravenous immunoglobulin (IVIG). Fourteen days after admission, her platelet count started to increase, $101{\times}103/ul$ at 16 days after admission. Trauma patients may carry various underlying diseases and thus trauma surgeons should always be aware and ready for peculiar situations.

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.

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.

Scutellaria baicalensis is known as a herbal medicine with anti-inflammatory and anti-oxidative activities. However, effect of Scutellaria baicalensis on lupus pathogenesis that is characterized by overproduction of proinflammatory cytokines and abnormalities in regulation, function, and interaction of immune cells remains unclear. We investigated effects of Scutellariae radix methanol extract (SBMeOH) on the production of proinflammatory cytokines and abnormal activation of T cells in vitro in pristane-induced lupus BALB/c mice. These results demonstrated that SBMeOH significantly decreased the LPS-stimulated production of $TNF-{\alpha}$, IL-6, and IL-10 by splenic and peritoneal macrophages and IL-6 and IL-10 by splenocytes from pristane-induced lupus mice. SBMeOH significantly downregulated the Con A-stimulated overproduction of IL-6, IL-10, and $IFN-{\gamma}$ by splenocytes from pristane-induced lupus mice. Also, SBMeOH significantly attenuated the Con A-induced expression of CD4+ T cells and CD69+CD4+ T cells but not CD8+ T cells in pristane-induced lupus mice. Our findings indicate that SBMeOH may ameliorate lupus pathogenic inflammation and autoimmunity via downregulation of proinflammatory cytokine production and abnormal activation of T cells.

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.

Lupus panniculitis is a rare disease that may present with similar clinical manifestations to an infection, such as cellulitis or abscess. This paper reports a case of a 25-year-old woman with systemic lupus erythematosus who underwent surgical intervention initially with the suspicion of an abscess but who was eventually diagnosed with lupus panniculitis. Despite the low incidence of lower leg involvement of panniculitis, clinicians should be aware of the possibility of an etiology other than infection when encountering patients with inflammatory diseases. Moreover, a skin biopsy and magnetic resonance imaging with a diffusion-weight image may be helpful.

Neonatal lupus erythematosus (NLE) is a rare disease characterized by typical clinical features and the transplacental passage of maternal autoantibodies, particularly anti-SSA/Ro. The major clinical manifestations are cutaneous lupus lesions, congenital heart block, hematological disorders, and hepatobiliary diseases. We report a case of NLE presenting with multiple round and oval target-like erythematous skin lesions and abnormal liver function, born to a clinically asymptomatic mother whose diagnosis was made retrospectively only after her newborn's diagnosis. Both the infant and the mother were positive for the anti-SSA/Ro and anti-SSB/La antibodies.

A 16 years old girl with systemic lupus erythematosus had a high fever for 20 days. Skin and renal biopsy showed diffuse granular deposits (IgG, IgM, $C_3$, $C_{1q}$ at dermo-epideral junction and IgG, IgA, IgM, $C_3$, $C_{1q}$, fibrinogen in the renal mesangium and segmentally along the capillary walls) which were compatable with systemic lupus erythematosus. The chest X-ray revealed patchy mottled densities in whole lung field when she complained more dyspnea at 9th hospital days. Even with the parenteral administration of broad-spectrum antibiotics, the symptoms of high fever, cough, tachydyspnea and hypoxia were continued. At 24th hospital day, the clinical course was rapidly deteriorated after sudden loss of consciousness with focal seizure which suggested CNS involvement during hydrocortisone administration for 10 days. She died of respiratory failure despite the mechanical ventilatory support with PEEP. The limited necropsy showed interstitial pneumonia, alveolar hemorrhage and occlusive necrotizing vasculitis of acute lupus pneumonitis.

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.
