BRIEF RESUME OF INTENDED WORK
6.1. Need for study
Skin forms not only a protective covering but is a part of the specialized immune
apparatus of the body. Immune perturbations as a part of disease pathogenesis are reflected in the skin and compared with other organ systems of the body. It is easily accessible for biopsy. By histopathology and direct immunofluorescence (DIF), presence of immune complexes in the skin biopsy at various locations such as the dermo-epidermal junction (DEJ), dermal blood vessels, etc. help to arrive at a diagnosis The aim of this study is to analyze the contribution of immunofluorescence in diagnosing noninfectious bullous lesions of the skin in comparison with histopathology and clinical diagnosis. The study is also undertaken to analyze the prevalence of various bullous lesions in the skin that are amenable to biopsy and are referred to an immunopathologist for definite diagnosis. This would help in understanding the relative prevalence of different vesiculobullous lesions presenting to a tertiary care center, VIMS,Bellary.
6.2 Review of Literature.
The bullous diseases have a history as old as that of medicine. In the early 1950’s, Lever was able to differentiate most of these by using histological criteria 1. The term pemphigus refers to a group of autoimmune blistering diseases of skin and mucous membranes which are characterized histologically by intraepidermal blisters due to acantholysis. Acantholysis is the characteristic feature of the bullae of pemphigus2 and is defined immunopathologically by the finding in vivo, of bound and circulating IgG directed against the cell surface of keratinocytes 1.
Acantholysis, a process by which epidermal cells lose their cohesiveness is the essential abnormality in the pemphigus group of disorders. Cytological examination (Tzanck smear) of the intact bulla is one of the methods for the demonstration of these acantholytic cells.2
A retrospective study at St. Johns hospital of 100 DIF’s( direct immunofluorescence),histology and clinic data on suspected vesiculobullous lesions of skin showed that sensitivity of DIF was 88% in Pemphigus group.82% in Bullous pemphigoid,and 28% in Dermatitis Herpetiformis.DIF is of great value in the diagnosis of vesiculobullous lesions, specially in clinical /histologic dilemma. 3
A Clinicopathological Study Of 22 Cases Of Pemphigus at JSS Medical College showed an accurate histological diagnosis is essential for the therapy. The association of clinical and histopathological features helps to arrive at the diagnosis in most cases. The study also revealed additional features which are not encountered normally, like the extrusion of adnexal structures into the bulla cavity and the extension of spongiosis and acantholysis into the adnexal epithelium.. Immunofluorescence study helped in confirming the diagnosis where histopathology and clinical features alone were inconclusive.4
A study done in Pakistan showed Pemphigus vulgaris was found to be the most frequent autoimmune blistering lesion of skin and Bullous pemphigoid was the most frequent subepidermal autoimmune blistering lesions.Direct immunofluorescent staining and subsequent microscopy is a useful tool in establishing the exact diagnosis of vesiculobullous disorders of skin..5
The most important techniques for the investigation of patients with noninfectious vesiculobullous disease are histopathology, and direct and indirect immunofluorescence. Research techniques such as immunoblotting and immunoelectron microscopy may refine the diagnosis in the individual patient but do not replace the clinical findings 6
Pemphigus may be precipitated by drugs (with or without antibody formation): penicillamine, captopril, enalapril and others and Neoplasia like lymphoma, bronchogenic squamous cell carcinoma and others8.
OBJECTIVES OF THE STUDY
1. To study the incidence of noninfectious vesiculobullous lesions in VIMS , Bellary
2 To correlate clinical, histologic findings and direct immunofluorescence study of various noninfectious vesiculobullous lesions.
MATERIALS AND METHODS
7.1. SOURCE OF DATA
The Clinical data and biopsies taken from the patients admitted or attending outpatient of Department of Skin &STD, VIMS, Bellary form the subjects and material for our study.
7.2. a) METHOD OF COLLECTION OF DATA
A written informed consent are taken from all patients included in the
Study. History-taking, relevant clinical findings and Tzanck’s smear will be done for these patients Skin biopsies obtained from these patients are submitted to Department of Pathology for a study period of one year, January 2011 to June 2012. The histopathological and immunofluorescent evaluations of biopsies are done in the Department of Pathology. Two biopsies are taken from each patient ,one is sent in 10% formalin for histopathology study and other in Michelle’s medium for DIF.The biopsy material sent in 10% formalin are subjected to routine processing and paraffin embedding. Multiple serial sections are taken from each biopsy and are stained with hematoxylin and eosin and special stain like PAS when required. Biopsies for DIF are obtained in holding fluid (Michelle's medium containing a saturated solution of ammonium sulfate in buffer at room temperature and stored at 4°C) is processed as follows. Before cutting, the biopsies are washed thrice in phosphate-buffered saline (PBS) (pH 7.2) for 15 min each time. Sections are taken with cryostat at 4– 5 micron thickness (minimum 10 sections) .For staining,the sections are first brought to room temperature. Optimally diluted fluorescein isothiocyanate (FITC)-labeled monospecific immunoglobulin’s (IgG, IgA, IgM, C3) are layered onto the sections and incubated at 37°C for 45 min– 1 h. Then, the sections were washed in PBS (pH 7.2, 0.1 M) thrice and mounted in buffered glycerin and finally viewed under Immunofluorescent microscope ,OLYMPUS-UCMAD-3,Prog ResCT3
INCLUSION CRITERIA
All patients presenting with Noninfectious vesiculobullous lesions including Drug eruptions presenting to Department of Skin And STD during January 2011 to June 2012.
EXCLUSION CRITERIA
Patients with genetic blistering diseases, bullous lesions due to physical ,chemical, biological, metabolic factors and eczemas.
b) SAMPLE SIZE AND DURATION OF STUDY:
Patients with vesiculobullous lesions presenting to Department of Skin &STD, are taken up for study at histopathology and immunology section of Pathology Department, VIMS Bellary between January 2011 to June 2012, subject to inclusion/exclusion criteria.
7.3. DOES THE STUDY REQUIRE ANY INVESTIGATIONS OR
INTERVENTIONS TO BE CONDUCTED ON PATIENTS OR OTHER
HUMANS OR ANIMALS?
Histopathology and Immunofluorescence are carried out with informed consent of patients. These investigations form part of special clinical management of patient. Histopathological and Immunofluorescence examination are done in Department of Pathology under guidance and supervision of guide.
7.4 . HAS ETHICAL CLEARANCE BEEN OBTAINED FROM YOUR
INSTITUTION?
Yes, Ethical Clearance has been obtained from Institutional Ethical Committee (IEC) of VIMS, Bellary.
