目的提高对老年系统性血管炎的认识。
方法回顾性分析2006年1月至2017年1月广州军区广州总医院收治的89例老年系统性血管炎患者的临床资料,重点分析其中合并肠梗阻的2例患者,分析其临床特点、诊疗过程以及预后。
结果老年系统性血管炎临床表现多样,发热为常见症状,常伴有乏力、咳嗽、头晕、胸痛、失眠等非特异性症状;全身各个脏器均可受累,以肾脏、肺脏受累最为常见;多数患者血沉、C反应蛋白可升高。合并肠梗阻的2例患者中,1例诊断为"过敏性血管炎",经激素联合吗替麦考酚酯治疗后病情好转;另1例因肠梗阻入院行手术治疗,误诊为"缺血性肠病",1年后患者出现进行性肾功能损害,血清胞浆型和核周型抗中性粒细胞胞浆抗体强阳性,修正诊断为"显微镜下血管炎"。因患者高龄未接受激素治疗,迅速出现急性肾功能衰竭,治疗无效死亡。
结论以肠梗阻为首发症状或并发症的老年患者需排除系统性血管炎,以免延误诊断治疗。 相似文献

系统性小血管炎的分类 总被引:2,自引:0,他引:2
过去的150年间,随着对肾、肺等活体器官病理研究及抗中性粒细胞胞浆抗体(anti-neutrophil cytoplasmic autoantibodies, ANCA)的发现,人们对血管炎发病机制研究的深入,小血管炎的分类发生了很大的变化.根据目前的分类方法,寡免疫性小血管炎包括Wegner肉芽肿(Wegner's granulomatosis, WG)、微型多血管炎(microscopic polyangitis, MPA)、Churg-strauss综合征(Churg-strauss syndrome,CSS)[1].这是一类与ANCA相关,临床又难以区分的系统性小血管炎,因而统称为ANCA相关性小血管炎(简称ANCA小血管炎).本文介绍血管炎分类的历史演变、ANCA致病机制,并对现行的血管炎分类进行评价. 相似文献

目的对我院24例抗中性粒细胞胞浆抗体小血管炎患者的临床资料进行临床分析。方法对确诊为抗中性粒细胞胞浆抗体小血管炎患者的临床表现、实验室检查、肾脏病理、诊治及预后进行分析。结果24例患者均为抗中性粒细胞胞浆抗体(ANCA)阳性,均有肾脏受累,同时还伴有肺、胃肠道、眼、耳、鼻、声带、皮肤、关节、甲状腺及外周神经受累。临床表现复杂多样,平均确诊时间为(9±4)个月。治疗以糖皮质激素加用环磷酰胺为主。总缓减率为78%。结论抗中性粒细胞胞浆抗体小血管炎为多系统受累疾病,漏诊误诊率高,早期诊治能提高生存率,但部分患者预后不佳。 相似文献

Although the presence of antineutrophil cytoplasmic antibodies (ANCA) has been reported in patients with systemic sclerosis (SSc), the association of SSc and systemic vasculitis has rarely been described. We obtained information on cases of systemic vasculitis associated with SSc in France from the French Vasculitis Study Group and all members of the French Research Group on Systemic Sclerosis.We identified 12 patients with systemic vasculitis associated with SSc: 9 with ANCA-associated systemic vasculitis (AASV) and 3 with mixed cryoglobulinemia vasculitis (MCV). In all AASV patients, SSc was of the limited type. The main complication of SSc was pulmonary fibrosis. Only 2 patients underwent a D-penicillamine regimen before the occurrence of AASV. The characteristics of AASV were microscopic polyangiitis (n = 7) and renal limited vasculitis (n = 2). Anti-myeloperoxidase antibodies were found in 8 of the 9 patients. The Five Factor Score was above 1 in 3 of the 9 patients. Of the 3 patients with MCV, Sjögren syndrome was confirmed in 2. We compared our findings with the results of a literature review (42 previously reported cases of AASV with SSc).Although rare, vasculitis is a complication of SSc. AASV is the most frequent type, and its diagnosis can be challenging when the kidney is injured. Better awareness of this rare association could facilitate earlier diagnosis and appropriate management to reduce damage. 相似文献

无肌病性皮肌炎15例临床分析 总被引:1,自引:0,他引:1
目的:探讨无肌病性皮肌炎(ADM)的临床特征、诊断、治疗和预后。提高临床医师对ADM的诊治水平。方法:将89例患者分为2组.其中有Gouron丘疹。或有眶周水肿性淡紫色斑疹,而临床缺乏明显肌炎者15例为ADM组,皮肌炎组(1)M组)74例。分别记录其临床特征、肌酸激酶、肌电图、肌肉病理检查、胸部影像学检查、器官受累情况、治疗方案和转归。结果:ADM组关节痛、发热、继发肺间质炎症和抗Jo-1抗体阳性的发生率分别为40%、13.3%、66.7%和13.3%,并发肿瘤6.7%,病死率20%。DM组关节痛、发热、肺间质炎症和抗Jo-1抗体阳性的发生率分别为37.8%、14.9%、32.4%和14、9%,病死率5.4%。二者比较,ADM组肺间质炎症发生率明显高于DM组。结论:ADM组虽然没有明显肌病表现,但是同样可以累及内脏,其中肺间质炎症的发生率较高,联合糖皮质激素和细胞毒免疫抑制剂治疗可以改善患者预后。临床医师需提高对ADM的认识。 相似文献

Systemic vasculitis (SV) involving abdominal structures usually has a poor prognosis. Gallbladder vasculitis (GV) has been reported as part of SV (GB-SV) and focal single-organ vasculitis (GB-SOV). We analyzed clinical and histologic characteristics of patients with GV to identify features that differentiate GB-SOV from the systemic forms of GV. To identify affected patients with GV we used pathology databases from our institution and an English-language PubMed search. Clinical manifestations, laboratory and histologic features, treatment administered, and outcomes were recorded. Patients were divided in 2 groups, GB-SOV and GB-SV. As in previous studies of single-organ vasculitis, GB-SOV was only considered to be a sustainable diagnosis if disease beyond the gallbladder was not apparent after a follow-up period of at least 6 months. Sixty-one well-characterized patients with GV were included (6 from our institution). There was no significant sex bias (32 female patients, 29 male). Median age was 52 years (range, 18–94 yr). GB-SOV was found in 20 (33%) and GB-SV in 41 (67%) patients. No differences were observed in age, sex frequency, or duration of gallbladder symptoms between groups. Past episodes of recurrent right-upper quadrant or abdominal pain and lithiasic cholecystitis were more frequent in GB-SOV patients, whereas acalculous cholecystitis occurred more often in GB-SV. In GB-SV, gallbladder-related symptoms occurred more often concomitantly with or after the systemic features, but they sometimes appeared before SV was fully developed (13.5%). Constitutional and musculoskeletal symptoms were reported only in GB-SV patients. Compared to GB-SOV, GB-SV patients presented more often with fever (62.5% vs 20%; p = 0.003) and exhibited higher erythrocyte sedimentation rate levels (80 ± 28 vs 37 ± 25 mm/h, respectively; p = 0.006). All GB-SV patients required glucocorticoids and 50% of them also received cytotoxic agents. Mortality in GB-SV was higher than in GB-SOV (35.5% vs 10%; p = 0.05). Nongranulomatous inflammation with fibrinoid necrosis of medium-sized vessels occurred equally in both groups (>90%). Forms of SV affecting the gallbladder included polyarteritis nodosa (n = 10), hepatitis B virus-associated vasculitis (n = 8), cryoglobulinemic (essential or hepatitis C virus-associated) vasculitis (n = 6), vasculitis associated with autoimmune diseases (n = 6), microscopic polyangiitis (n = 4), eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (n = 4), IgA vasculitis (Henoch-Schönlein) (n = 2), and giant cell arteritis (n = 1).GV is uncommon. Its histology most often consists of a nongranulomatous necrotizing vasculitis affecting medium-sized vessels. GB-SOV is usually discovered after routine cholecystectomy performed because of the presence of local symptoms, gallstone-associated cholecystitis, and contrary to GB-SV, GB-SOV is usually not associated with systemic symptoms. Acute phase reactants and surrogate markers of autoimmunity are usually normal or negative in GB-SOV. GB-SOV does not require systemic antiinflammatory or immunosuppressive therapy; surgery is adequate to achieve cure. GB-SV always warrants immunosuppressant therapy and is associated with high mortality. The finding of GV may precede the generalized manifestations of SV. Therefore, once GV is discovered, studies to determine disease extent and a vigilant follow-up are mandatory. 相似文献
