患者女性, 43岁。因反复血栓形成2年余, 血小板(PLT)减低1年余就诊。患者临床表现为反复动静脉血栓形成、少见部位血栓及抗凝治疗中新发血栓, 伴有进行性加重的血小板减少。外院及我院多次筛查抗核抗体、抗可溶性抗原抗体、抗磷脂抗体谱均为阴性。病程中糖皮质激素冲击及静脉免疫球蛋白(IVIG)曾使血小板升至正常, 骨髓巨核细胞成熟障碍, 支持免疫性血小板减低。入院后筛查易栓症的病因, 同时予肝素静脉泵入抗凝, 利妥昔单抗600 mg 1次;IVIG 20 g/d×3 d;口服艾曲波帕50 mg/d治疗。以上治疗3周后, 血小板减少无明显改善, 期间仍有新发血栓。后易栓症基因筛查回报PROS1基因杂合突变, MTHFR基因型为TT型, 发现少量IgGκ型M蛋白, 但仍不足以解释如此顽固的血栓倾向。在排除肿瘤、肝素诱导的血小板减少症等之后最终诊断血清阴性抗磷脂综合征可能性大。后续加用地塞米松20 mg/d×4 d, 联合口服西罗莫司2 mg/d加强免疫抑制, 抗凝方案过渡为低分子肝素后出院。1个月后电话随访, 患者颅内静脉窦血栓所致的头痛症状好转, PLT升至(20~30)×109/L, 无新... 相似文献

肺动脉高压(pulmonary arterial hypertension,PAH)是结缔组织病(connec tivetissue disease,CTD)常见且严重的并发症之一,与特发性肺动脉高压相比较,其生存率更低。目前PAH的发病机制尚不明确,但有证据显示肿瘤坏死因子-α(TNF-α)在结缔组织病和肺动脉高压发病过程中起重要作用,并且血清TNF-α升高与CTD-PAH的疾病进展相关。新开发的生物制剂(infliximab,etanercept,adalimumab)能够选择性阻断TNF-α,从而为PAH的治疗提供了新的机会。 相似文献

Objective To identify a novel auto-antibody in sera of systemic sclerosis (SSc) patients and to analyze its relevance with SSc-associated interstitial lung disease (ILD). Methods The anti-moesin antibody in the sera of 62 SSc patients, who had participated the European League Against Rheumatism's Scl eroderma Trial and Research Group (EUSTAR), were tested by enzyme linked immunosorbent assay (ELJSA). Patients were grouped by high resolution computerized tomography (HRCT) features, pulmonary function test (PFT) abnormalities, inflammatory markers and disease course. The prevalence and titer (Optical density value) of anti-moesin antibody were compared between groups with t and χ2 test. Results The titer of anti-moesin antibody was significantly higher in the SSc-ILD group than non-ILD group (0.156±0.062 vs 0.107± 0.026, P=0.005). Among SSc patients, the diagnostic sensitivity and specificity of the anti-moesin antibody for ILD was 44.0% and 91.7% respectively (Kappa=0.2, P=0.022). Anti-rnoesin antibody was more prevalent in SSc patients with HRCT features of honeycomb-like lesion, lobular septal thickening and mediastinal lymphadenopathy (P<0.05). SSc patients with deteriorated total lung volume (TLC %) had higher titer of anti-moesin antibody significantly (0.172±0.067 vs 0.133±0.039, P=0.011), as the same tendency in patients with decreased diffusing capacity of the lung for carbon monoxide (DLco% ) but without statistical significant difference (0.153±0.580 vs 0.120±0.340, P=0.089). The anti-moesin antibody was equally prevalent between abnormal ESR, C reactive protein, immunoglobulin and complements groups and their normal controls (P> 0.05). Group of patients who had SSc courses more than or less than 5 years demonstrated similar anti-moesin antibody titers (0.146±0.047 vs 0.164±0.077, P=0.272). However, patients with ILD courses less than 12 months had higher liter of the antibody than controls (0.182±0.073 vs 0.138±0.049, P=0.040). Conclusion This study suggests that the novel anti-moesin antibody has comparatively high specificity for SSc-associated ILD patients, which may contribute to further understanding the pathogenesis of ILD in SSc patients. Further investigations are deserved to evaluate the application of anti-moesin antibody in facilitating early screening and evaluation of ILD. 相似文献

目的 了解我国风湿免疫病患者新型冠状病毒(新冠)感染现状。方法 通过在线问卷的形式,收集风湿免疫病患者的原发病特征、新冠疫苗接种情况以及新冠感染的相关信息。结果 共5 468位受试者完整地填写了问卷,女性占84.5%,系统性红斑狼疮(33.7%)是最多的疾病类型,其中3 554人(65.0%)接种了至少1剂新冠疫苗,4 370人(77.9%)已感染新冠,231人(5.3%)因新冠住院治疗。多因素回归分析显示,使用利妥昔单抗治疗原发病是新冠感染的独立危险因素(P<0.05)。存在原发病相关的肺(OR 2.098,95%CI:1.546~2.847)、心脏(OR 1.625,95%CI:1.102~2.397)和胃肠道(OR 1.432,95CI:1.021~2.009)受累是新冠感染后需要住院治疗的独立危险因素,接种新冠疫苗加强剂是其保护性因素(OR 0.681,95%CI:0.468~0.991,P<0.05)。结论 本研究提供了部分中国风湿病患者新冠感染相关的数据,接种疫苗、原发病脏器受累和治疗均可影响新冠感染风险或预后。 相似文献

患者青年男性,早发心肌梗死,合并多囊肾,存在肾病综合征及抗磷脂抗体综合征,冠状动脉造影示多支冠状动脉瘤样扩张伴狭窄闭塞,植入支架后出现支架内反复再狭窄。抗磷脂抗体综合征为反复冠状动脉血栓形成的危险因素,且可累及肾脏并导致肾病综合征,而遗传性多囊肾可有肾病综合征临床表现且可因基因异常合并动脉瘤样病变。遗传因素、免疫因素、代谢因素等均参与其中,经多学科讨论并结合随诊结果,考虑患者为结缔组织病继发抗磷脂抗体综合征、肾病综合征和冠状动脉病变,针对原发病治疗后患者症状及指标均好转。本例患者的诊治拓宽了临床医师对年轻患者冠状动脉疾病背后病因的认识,也体现了多学科诊疗临床思维的重要性。 相似文献
