目的分析大疱性类天疱疮患者血清总IgE与抗BP180IgG抗体、抗BP230IgG抗体、抗表皮基底膜IgG抗体滴度(即间接免疫荧光滴度)的关系。方法收集沈阳市第七人民医院2014年1月-2020年1月大疱性类天疱疮病例,进行回顾性分析,根据抗BP180IgG抗体、抗BP230IgG抗体阳性情况将患者分组,比较组间血清总IgE值的差异。同时分析血清总IgE值与抗表皮基底膜IgG抗体滴度的相关性。结果收集病例119例。抗BP230IgG抗体阳性伴抗BP180IgG抗体阳性组血清总IgE值升高更显著,且与抗BP180IgG抗体及抗BP230IgG抗体均阴性组及仅抗BP180IgG抗体阳性组差异有统计学意义(P=0.000);而抗BP180IgG抗体及抗BP230IgG抗体均阴性组与仅抗BP180IgG抗体阳性组比较,血清总IgE值差异无统计学意义(P=0.777);血清总IgE值与抗表皮基底膜IgG抗体滴度呈正线性相关(r=0.548,P=0.000)。结论大疱性类天疱疮患者中,血清总IgE水平与表皮基底膜抗原暴露程度有一定相关性,且IgE可能主要与BP230结合在大疱性类天疱疮发病过程中起作用。  相似文献

【摘要】 目的 探讨抗幽门螺杆菌(Hp)抗体与慢性荨麻疹(CU)发病的关系。 方法 选择13C呼吸实验阳性、抗Hp抗体阳性的CU患者为实验组,健康人为对照组。用CU患者血清孵育人皮肤肥大细胞原代细胞株(HMC),检测血清是否可刺激HMC细胞释放组胺。用抗Hp抗体(IgG)刺激HMC细胞,检测其是否具有活化细胞释放组胺的作用。检测CU患者血清中是否也含有高亲和力受体(FcεRI)抗体或抗IgE抗体。分别用抗FcεRI抗体、抗IgE抗体刺激HMC细胞,检测其活化HMC细胞释放组胺作用。 结果 CU患者组血清活化HMC细胞释放组胺作用(3.13 ± 0.93)高于健康对照组(2.92 ± 0.75,t = 2.39,P < 0.05),4例CU患者血清中同时存在抗FcεRI抗体、3例存在抗IgE抗体。分别用这两种抗体阳性的CU患者血清孵育HMC细胞,释放组胺量均高于健康对照组(t值分别为4.82、6.34,均P < 0.01),但用只含有抗Hp抗体CU患者血清孵育HMC细胞无释放组胺作用(与健康对照组比较,t = 1.74,P > 0.05)。抗Hp抗体(IgG)无激活HMC细胞释放组胺作用(与阴性对照血清比较,t = 1.95,P > 0.05),抗FcεRI抗体、抗IgE抗体均可激活HMC细胞释放组胺(与阴性对照血清比较,t值分别为3.72、3.02,均P < 0.01)。 结论 抗Hp抗体对CU无致病作用,血清中同时存在抗FcεRI抗体或抗IgE抗体可导致部分Hp感染者同时患有CU。  相似文献

系统性红斑狼疮(SLE)患者的表皮基底膜上有各种免疫球蛋白和补体成分等沉着,但还没有见到免疫球蛋白E(IgE)沉着的报导。在免疫球蛋白中,一般认为IgE与先天过敏性疾病,特别是与即刻过敏反应型疾病有密切关系。关于SLE,最近相继有报告发表,认为在病情发展期,血清中的免疫球蛋白E浓度升高,而与血中抗核抗体的变动相一致,另外,有IgE抗核抗体的患者,肾病变化发生恶化的情况较之皮疹要多,因此IgE和SLE的关系受到人们重视。作者证明IgE在SLE的皮损及健康皮肤上均有沉着。其情况:1.表皮基底膜上:7例SLE患者中5例IgE为阳性,荧光类型呈现颗粒状或细颗粒状,沿表皮基底膜可以看到有连续性的分布,2.血管上:7例中4例为阳性,发现在真皮毛细血管甚至小血管上。3.表皮细胞核:仅1例在表  相似文献

During PUVA therapy 7 patients out of 34 with severe psoriasis developed circulating antinuclear antibodies (ANA) (21%). Before treatment only 3 patients of 50 (6%) considered for PUVA had detectable ANA. The ANA titres were usually low. Antibodies against native DNA as studied with the Crithidia luciliae test, were not found, and blood and urinary screening for collagenosis was negative. All 7 patients responded well to the PUVA treatment. The significance of these findings remains to be determined.  相似文献

Nucleosomes and the broad family of antinucleosome antibodies (ANAs; anti-double-stranded DNA, antihistone and antinucleosome antibodies) may contribute to the pathogenesis of systemic lupus erythematosus (SLE). We collected clinical information on 90 patients with SLE and 73 healthy volunteers and measured serum levels of the ANA family using a double-sandwich ELISA. The results showed that the levels of serum nucleosomes of patients with SLE was significantly lower and the levels of ANA were significantly higher than healthy controls. Negative correlations between serum nucleosomes and ANA, and positive correlations between individual ANAs were found. Patients with SLE with positive ANA had a significantly higher frequency of renal disorders than those with negative ANA. Determination of serum nucleosomes and ANAs contributes to SLE monitoring.  相似文献

Background Connective tissue diseases (CTDs) are a heterogeneous group of disorders defined by the association of a variety of clinical manifestations with immunologic and other laboratory findings. Overlap of syndromes and aberrant findings appear rather frequently. Methods Sera of eight antinuclear antibody (ANA) negative, cases of subacute cutaneous lupus erythematosus (SCLE) with antibodies to Ro (SS-A) and a ninth case with clinical and laboratory signs of Sjögren’s syndrome and systemic lupus erythematosus (SLE) were tested for complement (C′) fixing antinuclear antibodies (C-ANAs). The ninth case was examined in depth by direct immunofluorescence (DIF) and a two-step “C + DIF” test of biopsies for C′ fixation to in vivo bound ANAs, as well as serum tests for C-ANA, ANA, and SCLE markers. Results Sera of five of the eight ANA negative, Ro(SS-A) positive SCLE cases had C-ANAs. The ninth case, a 50-year-old woman with clinical and laboratory signs of Sjögren’s syndrome and SLE, gave a strong positive C + DIF reaction in the skin biopsy for in vivo bound ANAs that fix C′, but negative ANAs and C-ANAs in routine serum tests; they revealed antimitochondrial antibodies. Serum tests on normal skin, however, revealed weak ANA and strong C-ANA reactions with in vitro fixed C′. Conclusions ANA negative cases of SCLE or Sjögren’s syndrome may have C-ANAs. A case with Sjögren’s syndrome and signs of SLE had both in vivo and in vitro C′ fixing ANAs. C-ANA tests can aid in the identification of such cases.  相似文献

Psoriasis and systemic lupus erythematosus are common, but their coexistence is thought to be infrequent. Each of these diseases has a broad clinical spectrum, so that diagnosis may not be straightforward. This study aimed to investigate the following immunological parameters in psoriasis patients: (i) direct immunofluorescence (DIF); (ii) antinuclear antibody; (iii) anti-double-stranded DNA (dsDNA); (iv) anti-Ro; and (v) anti-nuclear ribonucleoprotein (nRNP). Of 300 cases, comprising 189 men (62.9%) and 111 women (37.1%), 17 (5.7%; 10 men, seven women) were positive for at least one immunological parameter. Nine of 300 (3%; seven male, two female) biopsy specimens from sun-exposed psoriatic lesions demonstrated bright continuous bands of granular IF along the dermoepidermal junction with immunoreactant immunoglobulin (Ig)G, IgM, C3 and fibrinogen. The intensity of IF at the dermoepidermal junction was graded 3+ and 2+. Three cases demonstrated IgM, two had IgG, two fibrinogen and six cases showed C3. Three cases demonstrated more than one immunoreactant. One case demonstrated C3 at the vessels. No specimen demonstrated IgA deposition. Three hundred sera were obtained from patients with psoriasis, of which five demonstrated elevated antinuclear antibody (ANA) titer; dilution titer varied from 1:80-640. Three had a homogeneous pattern and two had a speckled pattern. None had a peripheral pattern. Five (1.7%) of 300 demonstrated anti-Ro, two had negative ANA, and three were positive ANA, two of which were speckled and the other homogenous. Anti-dsDNA, anti-Sm and anti-nRNP were not detected. Ten patients had positive DIF but negative ANA, while five had positive ANA; all had negative DIF results. Thus, the incidence of psoriasis and lupus erythematosus coexistence is low and a baseline immunological screening test for psoriasis might not prove worthwhile.  相似文献

A 52-year-old woman suffering from eczematous, nodular, prurigo-like eruptions and systemic disorders including fever and weight loss revealed lymphadenopathy, hepatosplenomegaly, moderate eosinophilia, elevated levels of IgE, and positive ANA. Although the eosinophil count was not always “over 1500/mm3”, one of the criteria for diagnosis of hypereosinophilic syndrome (HES), this case may be considered as mild HES at present. The cause of eosinophilia in this syndrome remains uncertain.  相似文献

Fifty-one patients with lupus erythematosus were studied retrospectively. They were chosen on the basis of their antinuclear antibody (ANA) immunofluorescent pattern. Only those with the thready or the large speckle-like thready patterns were studied. Autoantibody profiles consisting of ANA, anti-single-stranded deoxyribonucleic acid (ssDNA) antibody, and anti-extractable nuclear antigen (ENA) antibody determinations were obtained. The patients with the thready ANA pattern and anti-ENA (Sm) antibodies had a significantly higher incidence of pulmonary, joint, and renal involvement than the anti-ENA negative patients with the large speckle-like thready pattern. There was also a significantly higher incidence of Raynaud's phenomenon in patients with the thready pattern than in those with the large speckle-like thready pattern. Photosensitivity was seen significantly more frequently in the patients with the large speckle-like thready pattern than in those with the thready pattern.  相似文献
