皮肤狼疮带试验对系统性红斑狼疮诊断的意义

目的：探讨狼疮带试验（LBT）在系统性红斑狼疮（SLE）诊断中的意义。方法：回顾分析32例LBT活检结果。结果：LBT在SLE中敏感性为78．13％。LBT与抗核抗体（ANA），抗ds—DAN抗体对SLE诊断的敏感性相近。SLE伴肾损害组LBT阳性率为90．48％，显著高于SLE不伴肾损害组54．55％。结论：LBT是SLE诊断的一项重要的辅助指标。     

Lupus nephritis and lupus band test.

Twenty-seven patients with histologically confirmed lupus nephritis were studied to identify the incidence of lupus band and its significance to histological patterns of nephritis and complement levels. It was found that the kidney involvement is 2.5 times more frequent in lupus band positive patients. The association of a positive lupus and low C3 level signifies the presence of diffuse proliferative glomerulonephritis rather than membranous glomerulonephritis. The results, together with earlier reports, are discussed.     

Pregnancy in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune disease that predominantly affects women of reproductive age. Pregnancy and its outcome is a major concern to most SLE patients. Queries regarding the risk of disease flares during pregnancy, chance of fetal loss, and the safety of various drugs are often raised. With the improvement in the understanding of the pathogenesis of SLE and the judicious use of immunosuppressive drugs, better disease control can now be achieved and SLE patients should not be deprived of the opportunity for bearing children. Prepregnancy counselling and close collaboration with other specialists such as the obstetricians and the perinatologists is essential in optimising the maternal and fetal outcome in lupus pregnancies. In this review, important issues regarding the fertility rate, optimal timing of conception, risk of disease flares during lupus pregnancy, pregnancy course, fetal outcome, safety of various drugs used for disease control during pregnancy and lactation, and contraceptive advice are discussed.     

Methylprednisolone in systemic lupus erythematosus

39 patients who received pulse methylprednisolone for disease manifestations of systemic lupus erythematosus were studied for zero to twenty-four weeks following therapy. Pulse methylprednisolone was given as intravenous infusions of methylprednisolone (10 mg/kg body weight) over one hour each day for three consecutive days. 27 (69.2%) patients were treated for lupus nephritis, 12 (30.8%) patients for non-renal manifestations of lupus. 17 (63.0%) of the renal lupus patients and 7 (58.3%) of the non-renal lupus patients showed clinical response. 11 (28.2%) patients had infections from which 7 (63.6%) died. Overall, 15 (38.5%) patients died. Early deaths (occurring within the first two weeks) were mainly due to disease activity while later deaths were mainly due to infection. In conclusion, the majority of lupus patients appeared to have had a beneficial response to pulse methylprednisolone therapy.     

Ptosis in systemic lupus erythematosus

Mild unilateral ptosis was observed in 11 women with systemic lupus erythematosus. It was associated with active disease in 8 patients, but only 2 had overt cerebral involvement. Isolated ptosis should not therefore be regarded as an indication of cerebral lupus.     

干扰素γ与系统性红斑狼疮

系统性红斑狼疮(systemic lupus erythematosus,SLE)的病因及发病机制至今尚未完全清楚,作为Th1型细胞因子之一的干扰素γ(IFN-γ)可能参与了SLE的发病及炎症过程。本文就近年来国内外对狼疮患者及狼疮鼠模型的血清、体外细胞培养分泌的IFN-γ水平、IFN-γ诱导蛋白和IFN-γ相关基因表达以及中医药治疗等方面的研究作一综述。     

Antinuclear antibodies in systemic lupus erythematosus

Autoantibodies to the three extractable nuclear antigens (ENA), Anti-SSA (Ro), Anti-Sm, Anti-RNP and antinuclear antibodies were determined in 150 patients with SLE. Seventy patients (46.7%) had Anti-SSA (Ro), 40 (26.7%) Anti-Sm and 25 (16.7%) Anti-RNP antibodies. Ninety four percent patients had a positive Fluorescent anti-nuclear antibody (FANA) test. The commonest FANA pattern is the speckled pattern. Subclinical keratoconjunctivitis sicca (KCS) was present in 60% patients. No correlation could be demonstrated between the presence of ENA autoantibodies and the clinical features of patients.
