Background Behçet's disease is a multisystem disease featuring mucocutaneous, ocular, articular, vascular, intestinal, urogenital, and neurologic involvement and occurs with a high prevalence in the Mediterranean including Turkey. Higher incidence of severe clinical course and systemic involvement is observed in male patients. Objective To determine the influence of sex on the clinical course of Behçet’ s disease. Methods We retrospectively evaluated the clinical findings of 2313 Behçet patients followed up at the multidisciplinary Behçet's Disease Center at Ankara University. Results The male/female patient ratio was 1.03. Oral aphthae was seen in all patients. In male Behçet patients, the prevalence of mucocutaneous lesions and systemic manifestations was as follows: 85.6% genital aphthae, 45.5% erythema nodosum, 59.5% papulopustular lesions, 17.5% thrombophlebitis, 38.1% ocular involvement, 11.3% articular involvement, 11.7% vascular involvement, 3.3% neurologic involvement, 1.4% gastrointestinal involvement, and 1.8% pulmonary involvement. In female Behçet patients, the prevalence of manifestations were as follows: 91% genital aphthae, 49.8% erythema nodosum, 48.3% papulopustular lesions, 3.5% thrombophlebitis, 19.8% ocular involvement, 11.8% articular involvement, 2.1% vascular involvement, 1.3% neurologic involvement, 1.4% gastrointestinal involvement, and 0.03% pulmonary involvement. Conclusions Only genital aphthae and erythema nodosum were more frequent in females. On the other hand papulopustular eruptions, thrombophlebitis, ocular, neurologic, pulmonary and vascular involvement were more frequent in males. While female patients had the best prognosis, male patients had a worse overall prognosis than females. 相似文献

We report a 6-year-old girl with recurrent oral aphthae, genital and perianal ulcers, and folliculitis-like erythema followed by intestinal symptoms. No ocular lesions were found. Her ailment was diagnosed as incomplete Behçet's disease with intestinal involvement. According to the literature, pediatric Behçet's disease is characterizesd by a low incidence of ocular lesions and a high incidence of intestinal involvement, as exhibited in this case. As intestinal lesions in pediatric Behçet's disease are often life-threatening, a barium enema must be given to exclude the possibility of intestinal involvement when pediatric patients with Behçet's disease complain of abdominal pain 相似文献

In the current study, we present guidelines for the diagnosis and treatment of the mucocutaneous lesions of Behçet's disease, which is a chronic inflammatory disease characterized by the involvement of various organs, including mucocutaneous, ocular, vascular, intestinal and central nervous system lesions. It is often identified in the Middle East Mediterranean to East Asia region. Skin manifestations include erythema nodosum, papulopustular lesions and thrombophlebitis, and mucosal manifestations include oral and genital ulcers. These mucocutaneous lesions are characteristically the first signs of Behçet's disease and are important to be recognized for the early diagnosis of the disease. Moreover, these manifestations also recur and persist over the long-term course of the disease. The management of mucocutaneous lesions is important to prevent recurrence. We developed consensus guidelines that provide recommendations for general practitioners and dermatologists and physicians on the management of the mucocutaneous lesions of Behçet's disease. 相似文献

Abstract Background Expression of bcl‐2 protein has been shown to play an important role in the pathogenesis of some inflammatory as well as neoplastic disorders. In this study we have investigated the presence of bcl‐2 protein in active skin lesions of Behçet's disease and compared these results with normal skin samples of Behçet's disease (BD) patients and BD unrelated leukocytoclastic vasculitis. Methods Active skin lesions of 23 Behçet's disease patients, normal skin samples of seven Behçet's disease patients, and archival biopsy specimens of 23 cutaneous leukocytoclastic vasculitis were investigated for the presence of bcl‐2 protein by immunohistochemical methods. Results of staining were assessed semiquantitatively. Chi‐square tests were used for statistical analysis. Results Expression of bcl‐2 protein were demonstrated in 16 of 23 (69.5%) and 8 of 23 (34.7%) patients with Behçet's disease and leukocytoclastic vasculitis, respectively. There were statistically significant difference between two groups (x2 = 4.27, P < 0.05). None of the normal skin samples of Behçet's disease patients showed bcl‐2 expression. Conclusion Expression of bcl‐2 protein may play a particular role in the development of skin lesions in Behçet's disease by causing prolonged survival of infiltrating lymphocytes. 相似文献

Background. Behçet's disease is a chronic, recurrent, inflammatory disorder characterized by the triad of oral and genital ulcers and ocular lesions. The etiology is unknown. This is the first report giving details of the clinical manifestations of Behçet's disease in Jordanian patients. Methods. Twenty patients with Behçet's disease were studied to determine the clinical pattern in the North of Jordan. The patients were seen in Princess Basma Teaching Hospital in North Jordan. They presented to various clinics and underwent full clinical examination. Data for each patient on all features of Behçet's disease were recorded on a standard form. A comparison was made between Behçet's disease in Jordan and other countries in the region. Results. Of the 20 patients, 14 were men and six women, giving a ratio of 2.3:1. Their ages ranged from 14 to 58 years. All had mouth ulcers, 65% genital ulcers, 65% ocular involvement, 55% joint involvement, 35% skin lesions, 20% vascular lesions, and 5% gastrointestinal involvement. The oral ulcers were the first manifestation of the disease process in 70% of our patients. Skin lesions, genital ulcers, and involvement of the central nervous system and the pulmonary system were less frequent in our study. Conclusions. Although it is difficult to obtain figures as to the incidence and prevalence of Behçet's disease in Jordan, the clinical manifestations, with a few exceptions, are similar to those in other countries in the region. 相似文献

Environmental chemicals (benzene hexachloride(BHC) and dichlor diphenyl trichlor ethane(DDT) as organic chlorides, Sumithion as an organic phosphorated compound and copper powder) were mixed together and administered orally to pedigreed Pitman-Moor's strain miniature swine for a period of about one year. Oral aphthae, folliculitis, cutaneous and subcutaneous nodules, genital ulcers, hyperemia of conjunctiva and intestinal ulcers were observed in all treated animals. Biopsy and autopsy specimens obtained from the experimental animals showed typical histopathological findings of human Behçet's disease. By ultrastructural X-ray microanalysis of peripheral neutrophils, vascular endothelial cells and infiltrated cells in affected lesions obtained from the experimental animals, highly significant amounts of chlorine and phosphorus were detected, mainly in the lysosomes. The incidence of Behçet's disease has been reported in countries where pesticides made from organic chlorine, organic phosphorus, arsenic and copper compounds have been used in massive amounts. Therefore, our findings suggest that these environmental chemicals play a main role in the pathogenesis of Behçet's disease. 相似文献

Over‐expression of bcl‐2 in lymphocytes has an important role in some immunological and inflammatory diseases. Fas (CD95) is a cell surface molecule that mediates receptor‐triggered apoptosis in various cells including autoreactive T cells. In this study we investigated bcl‐2 and Fas (CD95) expression in dermal lymphocytes in active skin lesions of Behçet's disease (BD) and in skin biopsy samples with chronic, non‐specific inflammations. Tissue sections of 29 skin lesions of Behçet's disease and of 10 chronic non‐spesific inflammatory process cases from the archives of the Ondokuz May?s University's Pathology Department were immunohistochemically stained for bcl‐2 and Fas (CD95), and lymphocytes in the dermal infiltrate were evaluated for cytoplasmic staining. bcl‐2 staining was observed in the skin lesions of 22 cases (75.8%) of Behçet's disease. bcl‐2 staining was detected in two (20%) control skin biopsy samples with non‐specific chronic inflammation. Fas (CD95) positivity was not detected in lymphocytes in Behçet's disease‐related skin lesions. Fas (CD95) staining was observed in only three skin biopsy samples with non‐specific chronic inflammation. bcl‐2 and Fas (CD95) staining values in Behçet's and non‐specific inflammation groups were significantly different (P < 0.01); differences in the bcl‐2 staining values between Behçet's patients with mucocutaneous involvement only and mucocutaneous and other systemic involvements were not significant (P > 0.05). Expression of bcl‐2 and loss of Fas (CD95) expression in dermal lymphocytes may play a role in the development of skin lesions and may account for the chronic course with periodic exacerbations in BD. 相似文献

Background Although papulopustular lesions are one of the diagnostic criteria for Behçet's disease, controversy exists as to the nature of these lesions. Specific vessel‐based papulopustular lesions as well as nonspecific follicular lesions may be seen in patients with Behçet's disease. Some authors suggest that papulopustular lesions should be considered a positive criterion only if they exhibit a vessel‐based neutrophilic reaction. Objective To determine whether specific vessel‐based papulopustular lesions can be differentiated clinically from nonspecific follicular lesions in patients with Behçet's disease. Methods Twenty‐three papulopustular lesions in 20 patients with Behçet's disease were initially examined clinically by two dermatologists blind to each other's diagnosis. Biopsies taken from these lesions were examined by a pathologist unaware of the patient data. Results Leukocytoclastic vasculitis or perivascular infiltration was observed in 10 lesions, perifollicular and perivascular infiltration was noted in nine lesions, and perifollicular inflammation was seen in four biopsy specimens. Most of the lesions interpreted clinically as specific papulopustular lesions of Behçet's disease had predominantly perivascular infiltration or leukocytoclastic vasculitis; however, three papulopustular lesions evaluated by both observers as specific papulopustular lesions had only perifollicular inflammation, and one lesion diagnosed clinically as a nonspecific follicular eruption revealed perivascular neutrophilic reaction. Interobserver variance was noted in three papulopustular lesions. Conclusions Clinical examination may not be sufficient to predict the dermatopathologic pattern in all lesions. Papulopustular lesions with no specific clinical and histopathologic features may create problems in the diagnosis of Behçet's disease. 相似文献

Mast cells in the upper dermis and mucosal subepithelial layer were counted in thirty consecutive light microscopy oil-immersion fields of the following: thirty-four skin and oral specimens from lesions in patients with active Behçet's disease, eight specimens of apparently uninvolved skin of the same patients, and 102 lesions of a variety of other skin diseases. The results revealed a significant increase in the number of mast cells in Behçet's lesions. Furthermore, the histamine content of five reactive lesions showed a two-fold increase compared with that in apparently uninvolved skin of patients with active Behçet's disease. It is suggested that mechanisms similar to cutaneous basophil hypersensitivity may be involved in the production of Behçet's lesions. 相似文献

Behçet's disease is a chronic systemic inflammatory disease involving mucous membranes, skin, eyes, the gastrointestinal tract, joints, blood vessels, and the neurologic system. Behçet's disease occurs endemically in the Middle East and Mediterranean regions. It is also distributed in the Central and Far Eastern Asian countries including Korea, Japan, and China. With the volume of clinical information obtained from over 5,000 patients who visited the Behçet's Disease Specialty Clinic, Severance Hospital, Yonsei University College of Medicine, informative and educational viewpoints of Behçet's disease including dermatologic and other systemic manifestations were introduced. 相似文献

Although Behçet's disease is mainly diagnosed during the reproductive periods of life, we know little about the influence of pregnancy on the clinical course of Behçet's disease. Therefore, we analyzed the relationship between Behçet's disease and pregnancy retrospectively, in order to detect any possible interaction between the two multisystemic processes, particularly in regard to the influence of pregnancy on the clinical course of Behçet's disease. We studied 44 pregnancies in 28 women with Behçet's disease. The diagnoses were made according to the criteria of the International Study Group for Behçet's disease. The patients were observed during pregnancy and puerperium periods at monthly intervals. The existence and incidence of symptoms were recorded during these periods. There was remission of Behçet's disease during 23 (52.3%) pregnancies, although the disease had been in a stage of exacerbation before pregnancy. The disease became exacerbated during 12 (27.3%) pregnancies, although it had been in a stage of remission before pregnancy. There were no changes in the clinical course of Behçet's disease in 9 (20.4%) pregnancies. The most frequent manifestations of the clinical exacerbation were increases in the intensity and severity of outbreaks of oral ulcers during pregnancy. Outbreaks of genital ulcers, eye inflammations, and arthritis were other signs of exacerbation. Other than spontaneous abortion in three patients, we did not observe maternal or fetal complications. Although Behçet's disease tends toward remission during pregnancy, the influence of pregnancy on its clinical course is quite variable between patients and even during different pregnancies in the same patient. On the basis of our and previous results, we speculate that pregnancy in general does not seem to markedly affect the natural course of Behçet's disease. 相似文献

There is no way of predicting whether a patient with recurrent oral ulcerations (ROU) will develop Behçet's disease (BD). In the absence of a valid laboratory test to exclude BD, such oral ulcerations result in a diagnostic problem when they occur as the sole and earliest manifestation of disease. We assessed the prognosis of ROU by performing prospective evaluations of 67 patients who had only a history of ROU and were registered at the Behçet's Disease Specialty Clinic at Severance Hospital of Yonsei University, Seoul, Korea. Thirty-five patients (52.2%) developed overt manifestations of BD at an average of 7.7 years after the onset of ROU. The frequency of recurrence was 9.8 times per year in progressive cases. From these results, it appears that highly recurrent ROU is a warning signal for BD. Careful examinations of patients, including their minor symptoms, additional laboratory tests, and regular follow-ups by physicians are required for proper diagnosis. 相似文献

Background Behçet's disease is a chronic, multisystem, inflammatory disease characterized by the predominance of T‐helper 1 cytokines. The disease is also characterized by infiltration of lymphocytes and neutrophils into the affected tissues. Because cytokines are involved in the regulation of lymphocyte and phagocyte functions, they may play an important role in the pathogenesis of Behçet's disease. Leptin, a member of the gp 130 family of cytokines, induces a strong T‐helper 1 response and is regarded as a proinflammatory inducer. Recent studies have shown that serum leptin concentration was increased in patients with Behçet's disease and correlated with disease activity. Objectives We aimed to investigate the role of G2548A polymorphism of leptin gene in patients with Behçet's disease and compare the results with healthy controls. Patients and methods A total of 93 subjects with Behçet's disease and 125 healthy controls were included in this study. Analyses of G‐2548A polymorphism of the LEP gene were performed using the PCR‐restriction fragment length polymorphism technique. The genotypes (GG, GA, and AA of leptin G2548A) and alleles (G and A of leptin 2548) were scored and the frequency was estimated. The frequencies of the alleles and genotypes in patients and controls were compared. We analysed the correlation between leptin gene polymorphism and the clinical features of BD. Results Both genotype and allele frequencies were not significantly different between controls and Behçet's disease patients [OR = 0.67, 95% CI (0.35–1.29), P = 0.197 and OR = 0.77, 95% CI (0.52–1.15), P = 0.184]. We did not find any significant relationship between leptin gene polymorphism and the clinical features of BD (P > 0.05). Conclusion In the present case‐control study, we found no evidence of an association between the G‐2548A variant of the leptin gene and BD among Turks. Further studies are needed to investigate serum leptin level to explain the mechanisms behind the lack of association between leptin G2548A gene polymorphism and BD. 相似文献

Five patients with Behçet's disease were satisfactorily treated with colchicine. Oral aphthosis, erythema nodosum-like lesions and genital erosions improved greatly within a month as did laboratory findings. We believe colchicine to be the first choice in the management of the cutaneous and ocular lesions of Behçet's disease. 相似文献

Introduction Behçet's disease is a rare, chronic disorder. The cause of Behçet's disease is unknown. It is believed to be caused by an autoimmune reaction. As in other chronic autoimmune diseases, Behçet's disease may show a subclinical adrenal failure and some changes in cortisol levels. We aimed to evaluate adrenal gland function in Behçet's disease patients. Material and method This study included 18 Behçet's disease patients and 15 healthy controls. Patient and control groups were administered i.v. 1 µg low dose test (LDT) and 250 µg standard dose test (SDT) adrenocorticotropic hormone (ACTH) stimulation test after 12 h of night fasting with an interval of 3‐days and cortisol responses in the 0th, 30th and 60th minutes were evaluated. Results There was no statistically significant difference between basal cortisol values of Behçet's disease and control groups. Cortisol values in the 60th minute in LDT were significantly lower in Behçet's disease group than in the control group. In the peak cortisol responses to LDT, a significant decrease was found in Behçet's disease group. Conclusion These findings suggest that hypothalamo‐pituitary adrenal axis is partially suppressed in Behçet's disease. 相似文献

Background Immune dysregulation has been shown to be one of the major aspects of the yet unknown pathogenesis of Behçet's disease. Interleukin-8 (IL-8), a major chemokine with pivotal effects concerning leukocytes and endothelial cells, has been found to be elevated in patients with Behçet's disease. Aim To evaluate the significance of elevated levels of IL-8 with respect to the activity of Behçet's disease. Methods Sixty-seven consecutive patients with Behçet's disease (37 males, 30 females; 32.5 ± 9.3 years) were enrolled in our study. The number of active clinical manifestations at the time of serum sampling was recorded. The degree of association between disease activity and IL-8, C-reactive protein, and erythrocyte sedimentation rate was assessed. Results Serum levels of IL-8 increased as the number of clinically involved organs increased (P < 0.05). C-reactive protein and the erythrocyte sedimentation rate showed no correlation with disease activity. Conclusions Our study confirms that the IL-8 level is a more sensitive marker of disease activity than the erythrocyte sedimentation rate and C-reactive protein. It may be assumed that IL-8 plays an important role in the pathophysiology of Behçet's disease. 相似文献

Background Chronic oral aphthae, recurrent genital ulcers and uveitis are the three main manifestations of Behçet's disease (BD). The aetiopathogenesis of BD is still obscure, but herpes simplex virus (HSV) is one of the possible causal factors. Various kinds of drugs, including immunosuppressants and aciclovir have been used in treatment, but effectiveness is variable. Objectives To demonstrate the efficacy of famciclovir, an antiviral compound that acts against HSV, varicella‐zoster virus and hepatitis B virus, in a murine model of BD. Methods Using the HSV‐induced BD mouse model, famciclovir was administered variously before and after inoculation or from the day of lesion occurrence, with appropriate controls. Ulceration of the mouth and genital skin and eye involvement were monitored. In addition, spleen cytokine expression was measured by polymerase chain reaction. Results Pretreatment and concurrent treatment did not affect the occurrence of BD, but treatment from the appearance of lesions was effective in improving BD and preventing recurrence. After famciclovir, interleukin 2 expression correlated with the recurrence of BD symptoms. Conclusions This model suggests the possible role of immune response to viral infection in the development and activation of BD. The study provides a rationale for clinical trials of famciclovir in the human form of BD. 相似文献

Summary Behçet's disease (BD) is a multisystem disease of unknown aetiology characterized by chronic relapsing oro‐genital ulcers, uveitis, and systemic involvement including articular, gastrointestinal, cardiopulmonary, neurologic and vascular pathology. Vascular involvement is observed in 30% of cases. Although the pathogenic mechanisms underlying the thrombotic disposition in BD are not well known, prothrombin (PT) gene mutations may be one factor that contributes to the development of vascular involvement in this disorder. We report a case of BD with a PT gene mutation, presenting with cardiovascular involvement. 相似文献

Systemic lupus erythematosus and Behçet's disease are known to be induced by immunoregulatory defects and to have some identical manifestations. Although the possibility of the coexistence of these disorders exists only one example of an association of these disorders has been described previously by Lee et al. Therefore, we describe an example of typical SLE with additional symptoms of Behçet's disease as a part of the symptom complex of SLE. 相似文献

Background Behçet's disease is a multisystem disease of unknown etiology. Caspase‐9 is responsible for initiating the caspase activation cascade during apoptosis. The aim of this study was to examine caspase‐9 expression in both endothelial and perivascular infiltrates of patients with active Behçet's disease. Methods Fifteen patients with active Behçet's disease, attending the First Dermatology Department, Ankara Numune Hospital, Ankara, Turkey between June 2003 and December 2005, were included in the study. Oral biopsy specimens from nine healthy volunteers were taken as the healthy control group, and skin biopsies from 18 psoriasis patients were used as the inflammatory control group. The specimens were examined with caspase‐9 primary antibody. Statistical analyses were performed using SPSS 11.5. Results The mean caspase‐9‐positive endothelial cell counts were 7.17 ± 2.45 in active Behçet's disease, 4.81 ± 0.76 in healthy controls, and 4.35 ± 1.34 in inflammatory controls. The difference between Behçet's disease and healthy controls was statistically significant, with increased endothelial staining in active Behçet's disease (P = 0.049). The difference between Behçet's disease and inflammatory controls was also statistically significant; the rate of staining was higher in Behçet's disease (P = 0.006). The mean caspase‐9‐positive dermal perivascular cell counts were 5.15 ± 2.32 in Behçet's disease, 3.32 ± 0.82 in healthy controls, and 5.54 ± 4.95 in inflammatory controls. These values did not show any statistically significant difference (P = 0.407). Conclusion Endothelial cells are one of the key cells in Behçet's disease, and our findings support the role of endothelial cells in the etiopathogenesis of Behçet's disease. 相似文献
