天疱疮及大疱性类天疱疮外观正常皮肤的免疫荧光检查

本文报告9例天疱疮及8例大疱性类天疱疮外观正常皮肤DIF检查结果.“正常”皮肤取自皮损外3cm、5cm及远隔部位,结果均为阳性.同时取自皮损材料对比检查,其反应情况与病期、病情、取材部位及皮损距离等均无明显差异.因此,采取“正常”皮肤作DIF检查对大疱性疾病的诊断是非常有价值的.

Frequency of IgA antibodies in pemphigus, bullous pemphigoid and mucous membrane pemphigoid

Circulating and bound IgA antibodies can be found in the autoimmune blistering diseases, but their prevalence, clinical relevance and target antigens remain unknown. Thirty-two patients with pemphigus, 73 with bullous pemphigoid and 28 with mucous membrane pemphigoid were studied retrospectively. Direct immunofluorescence (DIF) analysis of IgG, IgA, IgM and C3 was carried out for all cases. Sera were studied by standard indirect immunofluorescence, indirect immunofluorescence on salt-split skin, immunoblotting for bullous pemphigoid and mucous membrane pemphigoid and ELISA for pemphigus. With DIF, we found IgA autoantibodies in 22 of all 133 cases. Circulating IgA antibodies to skin were detected in 2 of 3 IgA-DIF-positive patients with pemphigus, in 3 of 6 with bullous pemphigoid, and in 6 of 13 with mucous membrane pemphigoid. We confirm that the IgA reactivity is more frequently associated with mucous membrane involvement, especially in cases without critical involvement (5/8). The role of IgA and its antigenic specificity in these diseases remain unclear.     

A Clinicopathological Study of Pemphigus in Eastern India with Special Reference to Direct Immunofluorescence

Background:Pemphigus is a group of chronic autoimmune vesico-bullous disorders in which the epidermis and the basement membrane zone are the focus of attack resulting in cutaneous and mucosal blister formation. Direct immunofluorescence (DIF) test is a very sensitive test for the diagnosisAim:To study the clinico histopathological patterns of pemphigus in eastern India. The study also aims to correlate DIF with clinical and histologic findings as well as severity of skin involvement [scoring systems].Results:In our study Pemphigus vulgaris (PV) was the predominant type with 32 cases followed by 8 cases of pemphigus foliaceus (PF) and a single case of IgA pemphigus. Mean age at presentation was late middle age. Majority of the patients, 26 (63.41%) initially had cutaneous involvement followed by mucosal involvement. In this study group 36 (87.80%) patients showed acantholytic cells on histopathological examination. Most patients of PV showed suprabasal blister 20 (62.50%) followed by intraspinous 5 (15.62%) and subcorneal 5 (15.62%) blister. In majority 28 (87.50%) of the PV patients IgG and C3 antibodies were deposited throughout the epidermis. The strength of antibody positivity was strong in most of the patients (71.87%). In cases of PF mostly IgG 6 (75%) antibodies were deposited in the upper epidermis. DIF intensity had poor correlation with disease activity/severity except in PF.Conclusion:Almost 85.36% cases of pemphigus were diagnosed clinicopathologically. But 6 cases couldn’t be diagnosed accurately on clinicopathological basis and in them DIF was confirmatory. Two cases of pure mucosal PV and 1 case of IgA pemphigus was confirmed by DIF. Two cases of bullous pemphigoid clinico-histologically mimicking PV were also excluded by DIF. So it appears from our study that DIF is confirmatory for diagnosis of pemphigus in all cases.     

IMMUNO-HISTOPATHOLOGY OF THE SKIN IN PEMPHIGOID

SUMMARY.— The in vivo direct immunofluorescent (DIF) staining patterns of the skin surrounding the lesions of 5 patients suffering from pemphigoid are reported.
It appeared that fine granular IgG deposits occur in the dermis and more closely packed in the junctional zone of most of the biopsies examined. Only 1 case with a very high (anti-basement membrane) IgG antibody titre showed a conspicuous linear fluorescence of the basement membrane zone, while 2 other cases with a less high antibody litre showed both types of staining patterns. The impression was gained that there is some relation between the antibody litre and the DIF staining pattern in DH.
The findings of this study are also in favour of the concept that pemphigoid and dermatitis herpetiformis are 2 different disease entities; however the existence of intermediate cases cannot be ruled out.
The advantages of the DIF method are discussed. An improved filter combination for blue narrow-band excitation and a rigid control of the conjugates used for IF studies are recommended.
