Behcet disease is a rare disorder characterized by recurrent oral and genital ulceration, eye lesions, and multiple skin lesions. The first modern description was in the 1930s by a Turkish dermatologist, Hulusi Behcet, who noted the triad of aphthous oral ulcers, genital lesions, and recurrent eye inflammation. A recent consensus conference identified several criteria to establish the diagnosis. Some of these parameters include:
Mucocutaneous lesions (oral ulcers-recurrent, at least three times per year)
Patients must also meet two of the following four criteria:
Recurrent genital ulcerations
Eye lesions (uveitis or retinal vasculitis)
Positive pathergy test (trauma induced lesions)
Skin lesions as diagnostic of Behcet's disease
The skin lesions range from leukocytoclastic vasculitis, pustular dermatitis, and clinical lesions resembling Sweet's syndrome, pyoderma gangrenosum, and erythema nodosum. Some investigators believe only cutaneous lesions containing infiltrates of neutrophils around blood vessels is diagnostic.
This disease is characterized by recurrence and relapse. Like many vasculitides, this disease may affect multiple organs. See the outline below for a detailed discussion.

PURPOSE: To determine the epidemiology of Behcet's disease in Western Switzerland and to study the characteristics of ocular disease.
METHODS: Patients newly diagnosed with Behcet's disease, seen from January 1990 to December 1998 at Hopital Jules Gonin, La Source Eye Center, and the Division of Immunology and Allergy, University of Lausanne, were analyzed. The Japanese diagnostic criteria for Behcet's disease were used and both complete and incomplete forms were included. Incidence, proportion of cases with ocular involvement, and the characteristics of ocular disease were determined.
RESULTS: During the follow-up period, a total of 35 Behcet's patients were seen in the three study centers. Twenty-five of these patients had ocular involvement. The incidences of Behcet's disease and Behcet's ocular disease in the western part of Switzerland, with a referral population of roughly 600000 persons, were 0.65 and 0.46 per 100000 per year, respectively. The mean age of the group was 33.2 years, age at presentation was 25.8 years, and mean follow-up was 5.7 years. The most frequent sign was oral aphthous involvement (86%), followed by ocular manifestations (72%). The HLA-B51 antigen was present in 66% of the patients with ocular involvement. Panuveitis was present in 20/25 patients (80%), anterior uveitis in 3/25 patients, and posterior involvement in 2/25 patients. Twenty-two patients (88%) had systemic treatment that always included corticosteroids; it was associated with other treatments in 17/22 patients. Mean duration of treatment was 45.5 +/- 25.1 (SD) months. The mean recurrence-free period in the six patients in whom treatment could be interrupted was 18.0 +/- 8.8 (SD) months. Visual function was maintained at the end of the follow-up for the collective and visual outcome was correlated to visual function at presentation.
CONCLUSIONS: The incidence of Behcet's disease in Western Switzerland was comparable to that in other western nonendemic countries. With early diagnosis and appropriate therapy, the prognosis was favorable in our collective of patients.

BACKGROUND: Defects in immune responses have been reported in patients with Behcet's disease (BD). To further characterize the immune dysfunction and its contribution to the pathogenesis, we have studied Fas ligand (FasL) expression in peripheral blood lymphocytes (PBL) and mononuclear cells in the skin lesions in patients with BD.
METHODS: FasL expression in PBL was studied with RT-PCR and immunoblotting with rabbit anti-human FasL antibody. We studied the expression of FasL in cryostat sections of biopsy specimens of erythema nodosum lesions from 4 patients with BD and of a genital ulcer lesion in another patient using immunohistochemical staining. Apoptotic cell death was detected with the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) method.
RESULTS: We found that FasL mRNA and FasL protein expression was detected marginally in the unstimulated PBL, and was induced upon activation in normal individuals. PBL from patients with BD exhibited an enhanced expression of FasL mRNA and FasL protein without in vitro stimulation. Moreover, mitogen stimulation failed to augment FasL expression of their lymphocytes, suggesting a dysregulation of FasL expression of PBL in patients with BD. The skin biopsy specimens revealed that cells infiltrating into skin lesions expressed FasL and there were several TUNEL staining-positive cells in the lesions, suggesting that Fas/FasL-mediated apoptosis is involved in the development of the skin lesion and thus may be associated with the pathogenesis.
CONCLUSIONS: We found an excessive expression of FasL in circulating as well as skin-infiltrating lymphocytes and the presence of apoptotic cells in the skin lesions, suggesting that lymphocytes expressing FasL aberrantly may play a role in the development and pathogenesis of BD.

BACKGROUND: Sweet syndrome (SS), an acute inflammatory disease, has clinical and laboratory features similar to those of Behcet disease (BD). Serum levels of granulocyte colony-stimulating factor (G-CSF) are elevated in patients with SS, and exogenous administration of G-CSF has repeatedly been implicated in the causation of SS. Granulocyte colony-stimulating factor is a hematopoietic growth factor that regulates the production and differentiation of neutrophils.
OBJECTIVES: To clarify the role of elevated serum G-CSF levels in patients with active SS and active BD compared with those with inactive SS or BD and healthy controls. To then analyze neutrophil apoptosis in the active state of SS and BD; and to also investigate the influence of autologous serum on neutrophil apoptosis.
METHODS: Serum G-CSF was examined in 5 patients with active SS, 7 with inactive SS, 7 with active BD, 9 with inactive BD, and 5 healthy controls by means of an enzyme immunoassay kit. We measured apoptotic cells in the neutrophil fraction of peripheral blood collections in patients with active diseases and controls by means of flow cytometry.
RESULTS: Serum G-CSF level was significantly higher in patients with active SS than in those with inactive SS. The difference in serum G-CSF levels among patients with active and inactive BD was also significant. Serum G-CSF level was significantly higher in patients with active SS than in those with active BD. Neutrophil apoptosis was significantly higher in patients with active SS than healthy controls. This increased apoptosis rate was also seen in patients with active BD. The increased rate of neutrophil apoptosis was significantly suppressed when the neutrophils were cultured for 18 hours in the presence of autologous active SS serum. Similarly, neutrophil apoptosis was suppressed in the presence of autologous serum in patients with active BD, but not significantly so.
CONCLUSIONS: These findings indicate that increased production of G-CSF in patients with SS and BD may play an important role in the manifestation of these disorders. Given the suppression of neutrophil apoptosis in the active state in the presence of the influence of autologous serum, which includes elevated G-CSF level, we propose that serum G-CSF plays a significant role in the suppression of neutrophil apoptosis. Furthermore, G-CSF-induced suppression of neutrophil apoptosis appears to be deeply involved in the pathogenesis of SS and BD

Background: Heat shock protein (60 kd HSP) has been implicated in the etiology of Behçet's disease, but its expression at sites of inflammation is unknown. Objective: Our aim was to investigate local HSP 60 expression and to quantify T-cell receptor (TCR) -positive cells, which are known to respond to HSP peptides.
Methods: Patients with active Behçet's disease (n = 21) and controls (n = 18) were included. Flow cytometric analysis was performed on peripheral blood to investigate TCR -positive cell counts. Biopsies were performed on active skin lesions, and immunohistochemical analysis was performed by a streptavidin-biotin method using the monoclonal ML-30 antibody; HSP staining intensity and distribution were evaluated in a blinded fashion. Immunhistochemical studies were performed to quantify TCR -positive cells at lesional sites.
Results: Mucocutaneous lesions of patients with Behçet's disease had statistically significantly increased expression of HSP 60/65. Peripheral blood TCR -positive cell counts were similar in both groups. However, lesional skin of patients with Behçet's disease had significantly increased -positive T-cell counts.
Conclusion: Up-regulation of HSP expression was found at lesional skin sites in Behçet's disease. The increased number of TCR -positive cells, which are known to respond to HSP peptides, may support the function of HSPs in the etiology of Behçet's disease. However, these findings may also be an epiphenomenon that needs to be further investigated.

Background: The origin of Behçet's disease (BD) is unclear. One of the prominent features of BD is vasculitis and thrombosis as a result of endothelial dysfunction. Because nitric oxide (NO) is synthesized by endothelium, we considered it as an interesting target of investigation in BD.
Objective: Our purpose was to define the level of NO in the serum of patients with BD and its relation with disease activity.
Methods: As an indicator for NO, serum total nitrite levels (end product of NO) were measured by Griess reaction in 52 consecutive patients with BD and compared with 32 age- and sex-matched healthy staff volunteers. Serum NO levels of active and inactive patients were compared.
Results: The overall serum nitrite levels in patients with BD (40.25 ħ 10.51 µmol/L) were significantly higher (P < .001) than those in healthy volunteers (25.09 ħ 5.33 µmol/L). The difference in serum total nitrite levels among patients with active BD (46.74 ħ 10.62 µmol/L) and inactive BD (33.24 ħ 3.73 µmol/L) was significant (P < .001). Significant differences were observed in serum nitrite levels between patients in the inactive period of BD and the control group (P < .001).
Conclusion: Increased NO production might be responsible for the overall inflammatory process of BD. NO seems to be related to disease activity.

Gammadelta T-cells participate in the immune response to infections and in autoimmunity by recognizing bacteria-derived and autologous antigens.
The goal of this study was to evaluate the involvement of gammadelta T-cells in Behcet's disease (BD). Gammadelta T-cells in the peripheral-blood mononuclear cells (PBMCs) of Israeli patients with definite BD (n = 23), normal controls (n = 16), and patients with familial Mediterrranean fever (FMF; n = 20) were evaluated by means of flow cytometry. The responses of patient and control gammadelta T-cells to medium conditioned by microorganisms cultured from an oral ulcer of a patient with active BD were compared. The proportions of CD3(+) and CD8(+) cells in the PBMCs were not significantly different between groups. In contrast, gammadelta-T-cells accounted for 7.01% +/- 4.42% of the PBMCs in BD compared with 3.56% +/- 3.45% in FMF (P < .005) and 3.7% +/- 3.15% in normal individuals (P < .009). Their numbers were significantly higher during active disease than in remission (9.45% +/- 5.08% versus 2.27% +/- 3.3%; P < .009).
The number of T-cell-receptor gammadelta(+) and Vdelta2(+) cells of BD patients, but not of controls, increased after 96 hours of culture in medium containing supernatant of microorganisms cultured from an oral ulcer in a patient with BD relative to their proportions in control medium: 58.2% vs 13.9% (P < .05) and 28% vs 9% (P < .04), respectively, of the cultured T-cells (n = 4).gammadelta T-cells are expanded in BD PBMCs during active disease.
An exaggerated proliferative response to products released by microorganisms present in oral ulcers may play a role in this phenomenon.

Involvement of the brain is one of the most important complications of Behcet's disease, but its diagnosis is difficult because of the lack of effective imaging tools.
Therefore, technetium-99m ethyl cysteinate dimer (Tc-99m ECD) single-photon emission computed tomography (SPECT) of the brain was used to detect abnormal regional cerebral blood flow in patients with neuro-Behcet's syndrome (NBS). Tc-99m ECD brain SPECT was performed to detect hypoperfusion areas of the brain in 10 NBS patients with definite neuropsychiatric symptoms or signs and normal brain magnetic resonance imaging (MRI) findings. Tc-99m ECD brain SPECT demonstrated hypoperfusion areas of the brain in all of the 10 NBS patients.
The parietal lobes were the most common areas with hypoperfusion lesions. Tc-99m ECD brain SPECT is a more sensitive and useful tool than brain MRI for detecting hypoperfusion areas of the brain in NBS patients.

OBJECTIVE: To analyse proinflammatory Th1 and Th2 cytokines in patients with Behcet's disease (BD) in relation to disease activity.
METHODS: Forty-five BD patients (25 in active stage) were investigated with ELISA for estimation of cytokines levels. Furthermore, cytokines intracellular synthesis (IL-4 and IFN-gamma) of CD4+ T cells was studied.
RESULTS: Active and in remission BD patients showed increased serum levels of Th1 (IFN-gamma, IL-12) and Th2 (IL-4, IL-6 and IL-10) cytokines. Active BD was characterized by a higher increase of IL-6, IL-10 and a striking increase of IL-17, IL-18 and IFN-gamma, compared to remission RD. Upon in vitro stimulation, the percentages of CD4+ T cells containing IFN-gamma and CD40L were higher in active BD compared to healthy controls.
CONCLUSION: Our results suggest that the microenvironment of CD4+ T cells in active BD may induce the production of more cells committed to Th1 than in BD patients in remission and healthy controls.

Behçet disease is an inflammatory disorder of unknown etiology showing diverse clinical presentations. Cardiac involvement is a critical problem that requires a timely diagnosis and management. However, clinicopathologic features have not been characterized clearly.
Here, we present clinicopathologic characteristics of this uncommon disease. Patients included 8 males and 4 females, ranging from 24 to 52 years old. They were presented with abrupt heart failure and were mostly diagnosed as having cardiac Behçet disease later in the course. Upon echocardiography, 8 patients showed severe aortic regurgitation with redundant prolapsing aortic cusps and 4 patients showed irregular mass lesions in the right ventricular cavity. No one had both lesions. The aortic root was also involved with aortic valvulitis, showing severe mixed acute and chronic inflammation of various stages. There were frequent microabscess and extensive endothelial loss with fibrinous deposit. The right heart lesions showed similar histopathologic features. Four patients who initially underwent simple aortic valve replacement developed serious postoperative complications requiring reoperations. No serious complications developed after the treatment was changed to a replacement of aortic root with extensive debridement and concomitant immunosuppressive therapy.
Cardiac Behçet disease is presented as aortic valvulitis/aortitis or inflammatory mass lesion. Characteristic echocardiographic and pathologic findings seem to be helpful for the timely diagnosis of this critical disease.

Among the cutaneous manifestations, nodular lesions are rather common in Behçet syndrome. The histologic nature of these lesions has been a matter of controversy.
To establish their distinguishing features, biopsy specimens from nodular lesions of 24 patients with Behçet syndrome, 25 with nodular vasculitis (NV), and 20 with erythema nodosum (EN) were compared. Statistical analysis revealed insignificant differences between most of the histologic features of Behçet syndrome and NV. However, neutrophil-predominating infiltrate in the subcutis was more common in Behçet syndrome, while necrosis and granuloma formation were encountered more frequently in NV. The differences between Behçet syndrome and EN were more significant. Septal panniculitis, lymphocyte-predominating infiltrate, absence of many vascular changes as well as vasculitis, and necrosis were features in favor of EN.
Nodular lesions of Behçet syndrome are mainly neutrophilic vascular reactions with histologic features similar to NV but significantly differing from EN associated with other systemic diseases.
Immunohistology of oral lesions from patients with recurrent oral ulcers and Behcet's syndrome.

Clin Exp Immunol 1989 Nov;78(2):189-95 Abstract quote
A qualitative and quantitative immunohistological investigation was performed on biopsies of oral ulcers from patients with Behcet's syndrome (BS) and those with recurrent oral ulcers (ROU). The results were compared with control oral biopsies from patients with other diseases and normal oral mucosa. The expression of HLA-DR on the cell membrane of keratinocytes was found in 13 out of 15 lesions from patients with BS and ROU, as compared with only one out of 15 controls.
The relative density of HLA-DR was investigated quantitatively by microdensitometry and this confirmed that DR expression in the epithelial cells of patients with BS and ROU was significantly greater than in diseased and normal control oral tissues. A prominent mononuclear cell infiltration consisted predominantly of T lymphocytes and mature macrophages. Analysis of the CD4 and CD8 subsets of T cells failed to show significant differences between BS, ROU and control diseased tissues. Increased numbers of Langerhans cells were found in the epithelium by morphometric analysis with the CD1 monoclonal antibody in BS and ROU but an increased number was also found in lichen planus.
The results suggest that the immunohistological changes in oral lesions of BS and ROU manifest an enhanced immune response in the epithelium, keratinocytes express HLA-class II antigen and increased number of Langerhans cells as well as in the lamina propria with a prominent infiltration of CD4, CD8 and macrophage-like cells.
The characteristic pattern of exacerbations and remissions of oral ulceration can be interpreted by the hypothesis that an initiating microbial agent may induce a mononuclear cell infiltration, with the release of cytokines, expression of class II antigen in keratinocytes and causing ulceration, followed by down-regulation of immunity by tolerant T cells induced by the class II positive keratinocytes, leading to a remission.

BACKGROUND: Recurrent aphthous stomatitis is a common problem with 20% to 50% of the population having experienced simple aphthous lesions (ie, canker sores). Complex aphthosis is the diagnosis given to patients with almost constant >3 oral aphthae or recurrent oral and genital aphthae in the absence of Behcet's disease.
METHODS: Eighty-one patients were referred to the Wake Forest University School of Medicine, Department of Dermatology from 1995 to 2001 with the diagnosis of presumptive Behcet's disease. After exclusion of patients with simple recurrent aphthous stomatitis or non-aphthous oral disease, 64 patients remained. Ten of the patients met criteria for Behcet's disease. The remaining 54 patients were evaluated and treated as patients with the diagnosis of complex aphthosis.
RESULTS: The 54 patients with complex aphthosis became the subject of this study. Twelve patients had secondary complex aphthosis with 10/12 having inflammatory bowel disease. The remaining 42 patients had primary (ie, idiopathic) complex aphthosis. The therapeutic ladder for these patients ranged from topical therapy through oral colchicine and combination oral colchicine and oral dapsone therapy to oral thalidomide therapy.
CONCLUSION: Complex aphthosis is an important condition to distinguish from Behcet's disease. Appropriate patient evaluation algorithms and treatment therapeutic ladders are proposed.

BACKGROUND: Eye involvement is the main cause of morbidity in Behcet's syndrome. The efficacy of the combined use of azathioprine and interferon alfa in treating this condition has not been studied.
METHODS: Ten male BD patients with retinal involvement but no irreversible structural changes were treated with azathioprine 2.5 mg/kg/day and IFN alpha 2b three times weekly for 24 weeks in an open trial. At week 24, IFN alpha was stopped and the patients continued to use azathioprine or received other immunosuppressives as indicated. Clinical response was assessed by visual acuity changes of either eye under the combination treatment and during the follow-up after stopping interferon.
RESULTS: As compared to the study entry, the mean visual acuities of either eye increased significantly at the end of the combination treatment (right eye 5.8 +/- 1.26 vs. 8.3 1.14; P = 0.043; left eye 6.3 1.15 SEM vs. 9.1 +/- 0.9 SEM; P = 0.027). The improvement in visual acuity persisted in the nine patients who were followed for 7.2 +/- 1.6 SEM months after stopping interferon. Reversible hematologic toxicity, mostly in the form of leukopenia, was detected in six patients during the combination treatment.
CONCLUSIONS: The combination of IFN alpha and azathioprine appears to be effective for eye involvement of BD. However, the frequent occurrence of myelosuppression mandates close monitoring.

OBJECTIVE: To determine the therapeutic efficacy of interferon alfa-2a in the treatment of Behcet disease.
DESIGN: A randomized placebo-controlled and double-blind study.
SETTING: University referral center.
PATIENTS: Fifty patients with Behcet disease were involved in the study.
INTERVENTION: The patients were given interferon alfa-2a, 6 x 10(6) IU, subcutaneously 3 times per week or placebo for 3 months, and examined clinically at weekly intervals.
MAIN OUTCOME MEASURES: For each mucocutaneous lesion and articular symptom, the mean frequency and duration were evaluated during the 3-month pretreatment, treatment, and follow-up periods. Pain for oral and genital ulcers was scored on a scale of 0 to 3. The ocular inflammatory score, the frequency of attacks, and changes in visual acuities for patients with ocular involvement were assessed before the study, at the end of treatment, and during the follow-up periods. In addition, overall responses at the end of the treatment period were graded as follows: complete remission, disappearance of all clinical signs and symptoms during treatment; partial remission, greater than a 50% decrease in the frequency, duration, and severity of pain for oral and genital ulcers and/or a decrease in the severity and frequency of ocular attacks; stable disease, less than a 50% change in the clinical signs and symptoms; and no effect or deterioration, ineffectiveness or worsening of clinical signs and symptoms.
RESULTS: Twenty-three interferon alfa-2a- and 21 placebo-treated patients, ranging in age from 16 to 55 years (mean +/- SD age, 32.38 +/- 7.94 years), were evaluable for efficacy. Interferon alfa-2a treatment significantly decreased the duration (P=.02) and pain (P=.01) of oral ulcers and the frequency of genital ulcers (P=.03) and papulopustular lesions (P=.01). The mean frequency and duration of erythema nodosum-like lesions (P=.77 and.27, respectively), thrombophlebitis (P=.29 and.61, respectively), and articular symptoms (P=.92 and.74, respectively) also decreased. But there were no statistically significant differences. An improvement in the severity and the frequency of ocular attacks occurred in 5 of 6 patients in the interferon alfa-2a-treated group and in 1 of 3 patients in the placebo-treated group. Of the 23 patients in the interferon alfa-2a-treated group, 15 responded to treatment (2 complete and 13 partial responses); and of the 21 patients in the placebo group, 3 responded to treatment (3 partial responses) (P<.005).
CONCLUSION: Interferon alfa-2a is an effective alternative treatment for Behcet disease, particularly for the management of the mucocutaneous lesions of the disease.
