小儿过敏性紫癜肾炎的预后影响因素   总被引:3,自引:2,他引:1  
小儿过敏性紫癜性肾炎(henoch schonlein purpura nephritis,HSPN)是小儿时期最常见的继发性肾小球肾炎,虽然HSPN患儿大多预后良好,但迁延不愈、发展成肾衰竭的也为数不少,国外有报道约15%~20%[1,2]患儿最终发展成慢性肾衰竭.由于HSPN的预后未必良好,在了解每个HSPN患儿的病情之后都应进行全面评估,并且随着病情的发展不断加以修正,这不仅便于及时向家长进行必要的交待,而且医生自己也可做到心中有数,努力采取适当的治疗措施.根据近些年的研究发现HSPN的预后与其临床类型、病理改变程度、病程进展、发病年龄等因素密切相关.  相似文献

过敏性紫癜性肾炎(HSPN)是由于过敏性紫癜(HSP)而导致的肾损害,是过敏性紫癜最严重的并发症,是影响过敏性紫癜病程、预后的决定性因素之一。HSPN发病机制尚未明确,但它属于自身免疫反应已为多数学者公认,越来越多的研究表明其发病诱因与细菌、病毒、支原体等感染后的免疫反应有关。HSPN是儿科常见的继发性肾小球肾炎,在儿童过敏性紫癜中高达20%~55%的患儿发生肾脏损伤。  相似文献

过敏性紫癜性肾炎的治疗   总被引:2,自引:0,他引:2  
过敏性紫癜(Henoch—Schoenlein Purpura,HSP)是一种小血管炎,主要特征是非血小板减少性紫癜、关节炎、腹痛和肾脏病变。1801年,由Heberden首先报道,Schonlein和Henoch随后也陆续报道。目前对于过敏性紫瘢的定义为:以IgA沉积为主的血管炎,主要累及皮肤、胃肠道、肾脏和关节。过敏性紫癜累及肾脏导致的肾脏病变称为紫癜性肾炎(HSPN)。  相似文献

目的 前瞻性观察来氟米特治疗不同病理类型的过敏性紫癜性肾炎(HSPN)的临床疗效。方法 将60例HSPN患者随机分为两组,治疗组每日给予来氟米特50mg,3d后改为20mg,完全缓解后减量至10mg,维持3个月;对照组给予传统的激素和抗过敏治疗(泼尼松每日30-50mg,尿蛋白完全消失后2周起逐渐减量至最小维持量)。两组均可加护肾、抗凝、降血压等药物治疗,3个月后分析结果。结果 治疗组24h尿蛋白定量、尿红细胞数明显减少,血浆白蛋白含量明显升高,与对照组的差异有统计学意义(P〈0.05),血肌酐浓度则无明显改变(P〉0.05)。治疗组完全缓解率为73.3%,明显高于对照组的46.7%/6(P〈0.05),副作用较少。结论 来氟米特治疗HSPN近期治愈率高,安全性好;远期疗效及安全性有待进一步探讨。  相似文献

过敏性紫癜又称亨诺一许兰综合征(Henoch-Schoenlein purpura,HSP),是儿童时期最常见的系统性血管炎之一,以非血小板减少性紫癜、腹痛、关节痛等为主要临床表现。该病极易累及肾脏,称过敏性紫癜肾炎(Henoch-Schoenlein purpura nephritis,HSPN)。HSPN的发病机制至今尚未完全阐明,近年的研究主要涉及免疫学因素异常,基因遗传多态性改变以及其他方面。  相似文献

过敏性紫癜(HSP)是一种以皮肤紫癜、出血性胃肠炎、关节炎及肾脏损害为主要特征的综合征,基本病变为全身弥漫性坏死性小血管炎,伴肾脏损害者称为过敏性紫癜性肾炎(HSPN),简称紫癜性肾炎。肾脏的受累直接影响预后,预后又取决于肾脏受累的病理类型及程度,本病大多呈良性、自限性过程,但也有反复发作或迁延数年,发展至慢性肾衰竭者。  相似文献

SUMMARY: A comparative immunohistological study was performed for the glomerular deposition of complements (C1q and C3c), fibrin/fibrinogen‐related antigen (FRA), the expression of intercellular adhesion molecule‐1 (ICAM‐1), and the infiltration of leucocytes bearing β2 integrins (leucocyte function associated antigen‐1 (LFA‐1), complement receptor 3 (CR3) and complement receptor 4 (CR4)) on renal biopsy specimens from 49 cases with Henoch‐Schoenlein purpura nephritis (HSPN), and 49 age‐matched cases with immunoglobulin A nephropathy (IgAN). the glomerular expression of ICAM‐1 was signifcantly correlated with the glomerular infiltration of leucocyte function associated antigen (LFA)‐1+ leucocytes in both diseases, and with that of CR3+ leucocytes in HSPN. the expression of ICAM‐1 was closely localized with the infiltration of LFA‐1+ leucocytes in the study with double immunostaining. the incidence and intensity of glomerular deposition of FRA were significantly higher in HSPN than in IgAN (P< 0.001), and those of C3c were significantly lower in HSPN than in IgAN (P< 0.001). the glomerular deposition of FRA was significantly correlated with the glomerular infiltration of CR4+ leucocytes in HSPN (P<0.05) but not in IgAN. In contrast, the glomerular deposition of C3c was significantly correlated with the glomerular infiltration of CR4+ leucocytes in IgAN (P<0.05), but not in HSPN. Studies with double immunostaining revealed a close association of CR4+ leucocytes with FRA deposition in HSPN and with C3c deposition in IgAN, respectively. the number of glomerular leucocytes bearing β2 integrins was significantly correlated with urinary protein at the time of renal biopsy in both diseases. These results suggested the differential roles of β2 integrins in the induction of glomerular injury in HSPN and IgAN. the ICAM‐1/LFA‐1 interaction may commonly be involved in the glomerular infiltration of leucocytes in both diseases. the ICAM‐1/CR3 interaction may be involved only in HSPN. Complement receptor 4 may function as a fibrin/fibrinogen receptor in HSPN, while CR4 may function as a complement receptor in IgAN.  相似文献

Background. The incidence of increased plasma IgE levels was reported to be significantly higher in Henoch-Schoenlein purpura nephritis (HSPN) than in IgA nephropathy (IgAN), and IgE deposits were demonstrated on epidermal Langerhans cells and dermal mast cells in four of six patients with HSPN in two European studies. We designed this study to investigate whether levels of clinical and biological markers of atopy in children with HSPN were significantly higher than those in children with IgAN, non-IgA glomerulonephritis (non-IgAGN), or microhematuria. Methods. The incidence of atopic disease, increased IgE levels, and positive radioallergosorbent test (RAST) results was investigated in 28 children with HSPN, 26 with IgAN, 28 with non-IgAGN, and 30 with microhematuria, all aged 8–16 years. All patients except for those in the microhematuria group, had proteinuria greater than100 mg/dl and had had a kidney biopsy. Results. The incidence of atopic disease, increased IgE levels, and positive RAST results in children with HSPN did not differ from findings in children with IgAN, non-IgAGN, or microhematuria. Conclusion. Our results in Japanese children do not support the idea (suggested by the two European studies) that IgE may play an important role in the pathogenesis of HSPN.

Objective To investigate the effect and the potential mechanism of splenic artery coarctation on the expression of iNOS and Th1/Th2 cytokines in spleen of cirrhotic rats with portal hypertension (PHT). Methods Cirrhotic rats were randomized into 3 groups (n= 10):sham operation group (SOG), splenic artery coarctation group (SAC) and splenic artery ligation group (SAL). Ten normal rats treated with sham operation were employed to serve as normal control group (NCG). Immunohistochemial staining was used to observe iNOS. RT-PCR was used to detect IFN-γ and IL-4mRNA. The Pearson's correlation analysis was used to investigate the relationship between iNOS and IFN-γ or IL-4. Results The expression of iNOS was increased significantly in spleen of cirrhotic rats as compared with NCG(P<0. 01). It was decreased after SAC and SAL compared with SOG (P<0. 01). The expression of IFN-γmRNA and IFN-γ/IL-4 of SOG were decreased but IL-4mRNA increased significantly than that of NCG(P<0.01). IFN-γmRNA was increased after SAC compared with SOG (P<0.05). IL-4mRNA was decreased and IFN-γ/IL-4 increased after SAC and SAL compared with SOG (P<0. 05). The expression of iNOS was negatively correlated with the expression of IFN-γmRNA(r=-0.672, P< 0.01 ) and positively correlated with the expression of IL-4 mRNA (r=0.634,P<0. 01). Conclusion The expression of iNOS is decreased and IFN-γ/IL-4 increased after SAC in spleen of cirrhotic rats with PHT and it may improve Th1/Th2 polarization by reducing the expression of iNOS.  相似文献
