目的:了解狼疮肾炎(LN)肾组织中CD134(OX40)的表达并探讨其与LN肾脏病理改变和肾功能损害的关系。方法:用免疫组织化学方法对40例LN患肾组织CD134的表达进行检测,并对其与LN的肾脏病理改变和肾功能损害的相关性进行分析。结果:LN患肾组织中,CD134表达显上调,尤其以WHO Ⅳ型LN更为明显。除系膜细胞、内皮细胞和远曲小管CD134表达明显增强外,肾间质毛细血管和大血管内皮细胞亦有CD134表达阳性的浸润细胞。LN肾组织加以表达与LN肾脏病理活动指数和肾功能损害显相关。结论:LN患确实存在CD134共刺激分子的异常表达,这在LN的发生和发展中可能起着重要的作用。 相似文献

朱辟疆 《中国中西医结合肾病杂志》2003,4(6):358-361
系统性红斑狼疮 (SLE)是我国最常见的风湿病之一 ,发病率约占 70例 /10万人口。SLE伴肾脏损害占 70 %以上 ,而病理检查几乎 10 0 %有肾脏损害。狼疮性肾炎 (LN)占我国继发性肾炎的第一位。LN的治疗近年来取得了重大进展 ,10年存活率已提高到 90 %以上。糖皮质激素及免疫抑制剂仍然是LN的首选药物 ,特别是美国国立卫生研究院(NIH)提倡的大剂量糖皮质激素联合环磷酰胺 (CTX)冲击方案使许多重型LN获得缓解。新的免疫抑制剂如环孢霉素A(CsA)及霉酚酸酯 (MMF)的问世又使部分难治性LN获得缓解。尽管如此 ,仍有许多问题未能解决 ,肾衰… 相似文献

AIMS: To determine the clinicolaboratory renal manifestations; glomerular, extra-glomerular histopathologic lesions; renal tubular dysfunction (RTD) frequency and outcome of a short-term renal follow up in Nigerian children with systemic lupus erythematosus (SLE). METHODS: A non-randomized prospective study of consecutive cases of childhood-onset SLE with nephropathy was conducted. Baseline/follow-up clinicolaboratory data were collected. Each patient was followed up for 12 months. RESULTS: Seven of the 11 children studied were girls. The median age at diagnosis was 11.0 years. Median diagnosis time interval (1.9 years) and median time of renal disease onset (1.0 year) were similar. Hypertension, nephrotic syndrome and acute renal failure (ARF) occurred in 45.5%, 54.5% and 63.7% of the patients, respectively. The glomerular lesions were non-proliferative lupus nephritis (LN) in 9.0% (class II LN); focal (class III LN) and diffuse (class IV LN) proliferative LN (PLN) in 27.0% and 64.0%, respectively. Tubulointerstitial nephritis (TIN, 91.0%) and RTD (64.0%) were common. ARF (P = 0.033) and RTD (P = 0.015) were significantly associated with severe TIN. Complete renal remission rate at end-point was 71.4%. Relapse and renal survival rates were 14.3% and 86.0%, respectively. RTD was persistent in 43.0%. CONCLUSION: Renal function disorders, diffuse PLN and extra-glomerular lesions were frequent. Significant association of ARF and RTD with severe TIN in this series suggests the need for early renal tubular function (RTF) assessment in our SLE patients. Deranged RTF may be marker of severe TIN in SLE warranting early confirmatory renal biopsy and aggressive interventional treatment. 相似文献

狼疮肾炎终末期狼疮活动情况和预后的观察 总被引:9,自引:0,他引:9
目的探讨狼疮肾炎(LN)患者发展至终末期肾病(ESRD)时狼疮活动情况和预后的关系。方法分析1987~1997年资料完整的71例LN的ESRD患者临床性SLE活动和血清学SLE活动的各项指标、死亡原因,分析比较LN的ESRD患者与非LN的ESRD患者的存活率。结果本组LN的ESRD患者在进行透析治疗前有648%已没有SLE临床活动表现。进行透析治疗后,SLE临床性活动渐趋静止状态,活动率从第一年563%下降至第十年28%;SLE血清学活动表现的消退,要比临床活动表现的消退缓慢;LN的ESRD透析治疗患者第2、5、10年的存活率与非LN透析患者相近,分别为796%、525%、305%,其死亡原因似与SLE活动无关。结论在LN的ESRD期间,SLE活动的静止趋势与时俱增,死亡原因与SLE活动性似无明显关系,LN的ESRD替代治疗患者的预后与非LN的ESRD替代治疗患者相同。当LN发展至不可逆的ESRD时,需长期作肾脏替代治疗,无必要再应用免疫抑制治疗。 相似文献

As one of the manifestations of patients with systemic lupus erythematosus, lupus nephritis (LN) has high morbidity and mortality. Although the explicit mechanism of LN remains to be fully elucidated, there is increasing evidence to support the notion that tumour necrosis factor‐related weak inducer of apoptosis (TWEAK), acting via its sole receptor, fibroblast growth factor‐inducible 14 (Fn14), plays a pivotal role in such pathologic process. TWEAK/Fn14 interactions occur prominently in kidneys of LN, inducing inflammatory responses, angiogenesis, mesangial proliferation, filtration barrier injuries, renal fibrosis, etc. This review will specify the important roles of TWEAK/Fn14 pathway in the pathogenesis of LN with experimental data from cellular and animal models. Additionally, the raised levels of urinary and serum soluble TWEAK correlate with renal disease activity in patients with LN. The neutralizing antibodies targeting TWEAK or other approaches inhibiting TWEAK/Fn14 signals can attenuate renal damage in the murine lupus models. Therefore, to focus on TWEAK/Fn14 signalling may be promising in both clinical evaluation and the treatment of patients with LN. 相似文献

SUMMARY: To clarify the characteristics of renal haemodynamics and their correlation with renal pathology in patients with systemic lupus erythematosus (SLE), renal function and renal biopsy findings from 101 SLE patients were analysed retrospectively. Glomerular filtration rate (GFR) and renal plasma flow (RPF) were examined simultaneously. Filtration fraction (FF) was calculated from the values obtained for GFR and RPF (GFR/RPF). The GFR was low in one-third and within normal limits in two-thirds of class IV patients with lupus nephritis (LN). In contrast, high RPF was observed in half of class IV patients. As a result, over 70% of class IV patients possessed a very low FF (less than 15%). The sensitivity of very low FF for class IV LN was significantly higher than that of low GFR. In conclusion, low FF was frequently recognized, especially in patients with diffuse proliferative LN. Decreased FF was a highly sensitive indicator of diffuse proliferative LN. Thus, determination of renal haemodynamics, including FF, may be a useful clinical parameter for evaluating renal involvement in patients with SLE. 相似文献

The objective of this study was to determine the clinical and histopathological features and outcome of children with lupus
nephritis (LN). Of 84 children with systemic lupus erythematosus (SLE), we retrospectively studied 58 children (69%) under
15 years of age with biopsy-proven LN who had been followed between October 1989 and January 2005. The mean age at diagnosis
or initial referral was 10.6 ± 2.25 years, and the mean follow-up was 5.3 ± 4.1 years. Class IV LN was observed in 34 (58.6%)
patients. The 5-year patient and renal survival rates were 82.5 and 78.5%, respectively, in the total group, and 75 and 85.8%,
respectively, in patients with Class IV LN. No independent predictor of unfavorable outcome, including renal histology, was
detected by multivariate analysis. The mid-term patient and the renal survival rates of Iranian children with biopsy-proven
LN are high. Within 5 years of follow-up, renal histology was not a predictor for survival. 相似文献

Tubulointerstitial nephritis is a less frequently recognized but important complication of systemic lupus erythematosus. We have investigated the cytokine beta2-microglobulin (beta2M) and Tamm-Horsfall glycoprotein (THG) excretions in the urine of systemic lupus erythematosus patients to identify indices for evaluation of tubulointerstitial inflammation in lupus nephritis (LN). Daily urine was collected from 15 patients with active LN, from 12 patients with inactive LN, and from 17 normal subjects. The amounts of soluble interleukin (IL) 2 receptor, IL-6, IL-8, beta2M, and THG in urine were measured. Beta2M and THG were regarded as indicators of proximal and distal renal tubule function, respectively. The urinary excretions of IL-6 and IL-8 were significantly higher in patients with active LN than in those with inactive LN and in normal individuals. The excretion of soluble IL-2 receptor in all three groups of subjects was not significantly different. On the other hand, the excretion of beta2M in patients with LN was significantly higher than that in normal individuals. The excretion of beta2M in patients with active or inactive LN was not significantly different. The THG excretion was lower in patients with active LN and tubulointerstitial inflammation as compared with patients with inactive LN or normal individuals. Six patients underwent pulse cyclophosphamide therapy during the course of experiments. Five of them showed a decrease in IL-8 and IL-6 excretions in urine after the treatment. The excretions of beta2M and THG in urine, in addition to IL-6 and IL-8, can reflect the renal inflammatory activity in patients with lupus tubulointerstitial nephritis as well as in those having lupus glomerulonephritis. 相似文献
