Arthropathy in Behçet's disease

Behcet disease: an undifferentiating and complex vasculitis

Behçet Disease is a relapsing and remitting variable vessel vasculitis characterized by recurrent mucocutaneous ulcers that can involve almost every organ system in the body. Indeed, the presence of recurrent oral or genital ulcers with other auto-inflammatory symptoms should raise suspicion for this elusive disease. It is unique among the vasculitides in that it can affect vessels of small, medium, and large size and tends to involve venous rather than arterial circulation, and its effects on the pulmonary venous circulation are particularly notable for their role in disease mortality. Classically seen in Mediterranean, Middle-Eastern, and eastern Asian countries, and relatively rare in the United States, prevalence has been increasing, prompting an increased need for internists to be aware of Behcet's clinical presentation and treatment. As early recognition and diagnosis of the disease is key to successful treatment and better prognosis, this review provides a brief summary of the current etiological theories, important clinical manifestations, and treatments including newer biologic alternatives.

Clinical Manifestations and Diagnosis of Axial Spondyloarthritis

BACKGROUND

Axial spondyloarthritis (axSpA) is a chronic, rheumatic disease characterized by inflammation of the sacroiliac joint, spine, and entheses. Axial spondyloarthritis affects up to 1.4% of adults in the United States and is associated with decreased quality of life, increased mortality, and substantial health care-related costs, imposing a high burden on patients, their caregivers, and society.

SUMMARY OF WORK

Diagnosing axSpA can be difficult. In this review, we seek to help rheumatologists in recognizing and diagnosing axSpA.

MAJOR CONCLUSIONS

A discussion of challenges associated with diagnosis is presented, including use and interpretation of imaging, reasons for diagnostic delays, differences in disease presentation by sex, and differential diagnoses of axSpA.

FUTURE RESEARCH DIRECTIONS

The early diagnosis of axSpA and advances in available therapeutic options have improved patient care and disease management, but delays in diagnosis and treatment remain common. Additional research and education are critical for recognizing diverse axSpA presentations and optimizing management early in the course of disease.

Behçet's Syndrome Apart From the Triple Symptom Complex: Vascular, Neurologic, Gastrointestinal, and Musculoskeletal Manifestations. A Mini Review

Behçet‘s Syndrome (BS) is a variable vessel vasculitis according to the Chapel Hill Consensus Nomenclature (1) and may thus affect any organ, including major and minor arterial and venous vessels to a varying degree and with varying frequency. Although the main features of BS are recurrent oral and genital aphthous ulcers, cutaneous lesions, ocular inflammation and arthritis—major vessel and life—or organ threatening involvement of internal organs and the central and peripheral nervous system occur. In general, BS in Europe appears to form six phenotypes of clinical manifestations (2), which are (1) mucocutaneous only, (2) predominant arthritis/articular involvement, (3) vascular phenotype, (4) ocular manifestations, which are most likely associated with CNS manifestations and HLA-B51, (5) dominant parenchymal CNS manifestations (being associated with the ocular ones), and (6) gastrointestinal involvement. Mucocutaneous manifestations are present in almost all patients/all phenotypes. In the following review, we summarize the current knowledge concerning vascular, neurologic, gastrointestinal and musculoskeletal manifestations of the disease.

A case with Behçet's disease involving erosive Metacarpophalangeal joint arthritis: the value of ultrasonography in the diagnosis of an Erosion

Background

Behçet’s disease (BD) is a chronic multisystemic vasculitis that may emerge with musculoskeletal system involvements, oral-genital recurrent aphthae, mucocutaneous lesions, and ocular symptoms. Arthritis in BD is usually non-erosive and not related to crippling disease. Erosive arthropathy is a very rare manifestation of BD.

Case presentation

Herein, we present a 60-year-old male patient suffering from BD for 33 years with erosive arthritis in his second metacarpophalangeal joint. After we assessed his finger by X-ray, we diagnosed erosive arthropathy quickly by musculoskeletal ultrasonography. In addition, a systematic literature search was performed via the PubMed and Scopus databases using the keywords, ‘Behçet’s disease [AND] erosive/destructive arthritis’.

Conclusions

Erosive arthritis due to BD can be evaluated by ultrasonography in an easy, fast and cost-effective manner. The literature search between 1985 and December 2019 revealed a total of 19 patients with peripheral erosive arthropathy related to BD and the characteristics of the results are summarized in the paper.

Retinal vasculitis with Chronic Recurrent Multifocal Osteomyelitis: a case report and review of the literature

Background

Concurrent presentation of retinal vasculitis with mixed sclerotic and lytic bone lesions is rare.

Case presentation

We present the case of a 37-year old woman with a several year history of episodic sternoclavicular pain who presented for rheumatologic evaluation due to a recent diagnosis of retinal vasculitis. We review the differential diagnosis of retinal vasculitis, along with the differential diagnosis of mixed sclerotic and lytic bone lesions. Ultimately, bone marrow biopsy confirmed diagnosis of chronic recurrent multifocal osteomyelitis (CRMO). Concurrent presentation of CRMO with retinal vasculitis is extremely rare but important to recognize. The patient demonstrated clinical response to prednisone and tumor necrosis factor-alpha inhibition (TNF-i).

Conclusion

This case reports and unusual presentation of CRMO spectrum disease involving the sternum and sternoclavicular joint with concurrent retinal vasculitis.

What Is Vascular Behçet's Disease?

Vascular Behçet's disease (BD) would keep risk of anastomotic pseudoaneurysm due to deterioration of the disease even after vascular surgery was successfully done. Therefore, it is one of the least-welcome diseases for vascular surgeons. There still exist several points on a concept and criteria of the vascular BD which not only general practitioners but also the vascular surgeons do not understand. Clinical findings strongly suspecting vascular BD are follows; saccular aneurysms without atherosclerosis developed in younger than 50-year-old patients, superior vena cava syndrome or deep vein thrombosis in bilateral legs without apparent causes, and multiple superficial thrombophlebitis, etc. It is very difficult to make a diagnosis of BD in the patients whose onset of the disease is a vascular lesion, because vascular BD combines few ocular lesions. In such case, it is very important to find out not only oral and genital ulceration, but also past history of arthritis. To establish the vascular BD, we vascular surgeons have to collect cases of the vascular BD and to revise criteria of the disease. (This is a translation of Jpn J Vasc Surg 2017; 26: 19-23.).

Autoinflammatory Diseases and Physical Therapy

Autoinflammatory diseases (AIDs) constitute a group of clinical conditions, characterized by recurrent episodes of systemic inflammation, due to dysregulation of the innate immune system, without involving autoantibodies or antigen-specific T-cells. The patients exhibit recurrent episodes of fever with potentially serious complications and may have classic rheumatologic symptoms, including joint, skin, eye and muscle inflammation. Therefore, musculoskeletal problems and impaired quality of life can be anticipated as unavoidable consequences. In this regards any approach to ease the burden of symptoms and compensate the functional deficits are the main objectives of rehabilitation approach. For patients with inflammatory arthritis, physical therapy and rehabilitation methods have an important role in reducing joint pain and stiffness, preventing deformity, reconstructing muscle tissue and improving function. In order to justify the integration of rehabilitation approach in the management of AIDs and to determine the optimal protocols to use in this group of patients, well-designed, comprehensive, longitudinal, clinical trials using physical therapy centred outcomes are greatly needed.

Carpal Tunnel Syndrome in Behçet's Disease

PURPOSE

Behçet's disease (BD) is a chronic inflammatory disease characterized by orogenital ulcers, skin and ocular lesions, in addition to articular, vascular, and neurologic symptoms. Carpal tunnel syndrome (CTS), can also occur in BD patients secondary to inflammation in the connective tissues, vessels, and tendons, as well as nerve involvement in BD itself. However, reports of patients who have CTS in BD are rare. The aim of this study was to evaluate the clinical characteristics of CTS in BD patients.

MATERIALS AND METHODS

Retrospective analysis of the medical records of 1750 BD patients, and 14 (0.8%) BD patients who were diagnosed with CTS was performed at the BD Specialty Clinic of Severance Hospital. Patient demographics, disease activity/severity for both diseases, and the clinical characteristics of CTS in BD were recorded and analyzed.

RESULTS

All 14 BD patients with CTS were women. Twelve patients (85.7%) were diagnosed with active BD. The CTS was mild in 8 patients (57.2%), moderate in 3 patients (21.4%), and severe in 3 patients (21.4%). Ten patients (71.4%) had BD prior to the diagnosis of CTS, and these 10 patients all had active BD.

CONCLUSION

CTS can occur as a result of the inflammation associated with BD and can also be the presenting symptom of nerve involvement in BD. CTS can also develop as the initial symptom of BD. Therefore, a higher degree of suspicion should be maintained for CTS in patients with BD and vice versa; however, the exact relationship is uncertain.

Prospective study of articular manifestations in Behçet's disease: five-year report

AIM

To evaluate different aspects of articular involvements (prevalence, types, relation to extra-articular manifestations, etc.) in Iranian patients with Behcet's disease (BD).

METHODS

In a prospective study, all patients with BD attending an outpatient BD clinic were enrolled. The type of articular involvements (peripheral or axial), involved joints, duration of attacks and their relation to extra-articular manifestations, human leukocyte antigen (HLA)-B5 and HLA-B27 were evaluated. Data analysis was done by using descriptive statistical indices such as mean and confidence interval. The comparisons were done by chi-square test.

RESULTS

In a 5-year period, 2312 patients were recruited. Musculoskeletal manifestations were recorded in 430 patients (190 without previous history of these involvements). The remaining 1882 patients showed no musculoskeletal involvements, of which 753 had past histories of musculoskeletal manifestations. The 5-year incidence rate was 18.6%, and the prevalence rate was 51.2%. History of previous musculoskeletal involvements has no effect in its new development (P = 0.2). Arthritis was the most common type of involvement (289/430, 67%). The most frequent pattern was monoarthritis (191/289, 66%), and the most frequent involved joints were knees (147/289, 50.9%). The arthritic attacks were unilateral in 82.4% of cases. Ankylosing spondylitis was seen in 44/430 (10.2%). There was no association between HLA-B5 or HLA-B27 and any type of musculoskeletal involvements (P > 0.5). Pseudofolliculitis was the only extra-articular manifestation related to arthritic attacks (P = 0.046).

CONCLUSION

Musculoskeletal involvement is a common manifestation of BD seen in more than half of patients. Acute knee monoarthritis was the most common pattern of articular involvement in BD.

Behçet syndrome: from pathogenesis to novel therapies

Behçet syndrome is a chronic disease hallmarked by inflammation of the blood vessels that is related to an autoimmune reaction caused by inherited susceptibility due to specific genes and environmental factors, probably components of infectious microorganisms, which turn on or get going the disease in genetically susceptible subjects. The more common clinical expression of the disease is represented by a triple-symptom complex of recurrent oral aphthous ulcers, genital ulcers, and uveitis, sometimes associated with inflammatory arthritis, phlebitis, iritis, as well as inflammation of the digestive tract, brain, and spinal cord. The treatment strategies used to manage the manifestations of Behçet syndrome have gradually progressed, and a number of new therapeutic resources have been implemented in recent years, allowing better control of pathogenic mechanisms, reducing symptoms and suffering, and ameliorating patient's outcome.

Demographical and Clinical Characteristics of Behcet's Disease in Southeastern Turkey

BACKGROUND

We aimed to determine the demographic and clinical features of patients with Behcet's disease (BD) in Southeastern Turkey.

METHODS

In this study, files of 132 patients with BD (76 females and 56 males) who were diagnosed with BD according to the International Study Group criteria at the Department of Dermatology of Dicle University Faculty of Medicine from 2005 to 2009 were evaluated retrospectively. Demographical and clinical characteristics of the cases were recorded.

RESULTS

Mean age of the cases was 32.40 ± 9.4 years (range 15 - 59 years) and male/female ratio was 0.73. The mean age at diagnosis was 28.71 ± 9.1 years. Six cases were diagnosed as juvenile BD (4.45%). Oral aphthous lesions (100%) and genital ulcers (94%) were found to be the most common findings of the disease, followed by pathergy positivity (75%), papulopustular lesions (74.2%), erythema nodosum (43.2%), thrombophlebitis (6.8%) and extragenital ulcers (6.1%). Systemic involvement was noted as joint involvement in 79.5%, ocular involvement in 28.8%, vascular involvement in 9.8%, pulmonary involvement in 2.3%, neurologic involvement in 2.3% and genitourinary system involvement in 0.8%. There was no significant difference between mucocutaneous findings and systemic involvement ratios of male and female cases.

CONCLUSION

Demographic and clinical features of BD may vary according to geographical region, gender and ethnicity. We hope that this study will contribute to the epidemiologic data of BD which may exhibit different clinical and demographic features in different parts of the world.

Refractory pseudoseptic arthritis in Behçet's disease successfully treated with infliximab: a case report and literature review

Arthritis associated with Behçet's disease is typically nonerosive and nondeforming, and most patients respond to colchicine treatment. However, destructive arthritis and refractory arthritis have also been reported on occasion. Elevated white blood cell counts may occur in synovial fluid in BD, but pseudoseptic arthritis is a very rare event in this disease. We report a patient with BD and rapidly progressive deforming pseudoseptic arthritis refractory to colchicine, corticosteroids, and methotrexate, who entered remission after infliximab treatment.

Behçet's disease with severe destructive arthritis

Abstract Behçet's disease is a systemic disease characterized by oral aphta, genital ulcers, and ocular lesions, and arthritic manifestations also appear to be common. However, this disease rarely produces loss of function or deformity in arthritic joints. We report the case of a 52-year-old woman with Behçet's disease who had a history of recurrent oral aphta, genital ulcerations, and intestinal lesions for almost 30 years. When she was about 30 years old, she began to notice significant morning stiffness and polyarthritis, and progressive destructive arthritic changes in the bilateral fingers, wrists, and left ankle. Behçet's disease with severe destructive arthritic changes is rare, and the underlying mechanism is still unknown.

Ocular Behçet disease: current therapeutic approaches

PURPOSE OF REVIEW

To alert physician to timely recognition and current treatment of recurrent hypopyon iridocyclitis or panuveitis in ocular Behçet disease (OBD).

RECENT FINDINGS

Interferon-α, rituximab, intravitreal triamcinolone, and biological response modifiers by tumor necrosis factor inhibitors such as infliximab and adalimumab are being used increasingly for the treatment of severe sight-threatening ocular inflammation including retinal vasculitis and cystoid macular edema (CME).

SUMMARY

Biological agents offer tremendous potential in the treatment of OBD. Given that OBD predominantly afflicts the younger adults in their most productive years, dermatologist, rheumatologist, internist, or general practitioners supervising patients with oculo-articulo-oromucocutaneous syndromes should be aware of systemic Behçet disease. Early recognition of ocular involvement is important and such patients should strongly be instructed to visit immediately an ophthalmologist, as uveitis management differs from extraocular involvements with high ocular morbidity from sight-threatening complications due to relapsing inflammatory attacks in the posterior segment of the eye. A single infliximab infusion should be considered for the control of acute panuveitis, whereas repeated long-term infliximab infusions were proved to be more effective in reducing the number of episodes in refractory uveoretinitis with faster regression and complete remission of CME.

Musculoskeletal Findings in Behcet's Disease

Behcet's disease is a multisystem disease characterized by recurrent oral and genital ulcers, relapsing uveitis, mucocutaneous, articular, gastrointestinal, neurologic, and vascular manifestations. Rheumatologic manifestations may also occur in Behcet's disease, and arthritis and arthralgia are the most common musculoskeletal findings followed by enthesopathy, avascular necrosis, myalgia, and myositis. Although the main pathology of Behcet's disease has been known to be the underlying vasculitis, the etiology and exact pathogenesis of the disease are still unclear. Musculoskeletal findings of Behcet's disease, the relationship between Behcet's disease and spondyloarthropathy disease complex, and the status of bone metabolism in patients with Behcet's disease were discussed in this paper.

Destructive arthritis in Behçet's disease: a report of eight cases and literature review

Behçet's disease (BD) is a multisystemic disease with typically non-erosive and non-deforming joint manifestations. The occurrence of destructive arthritis in Behçet's disease has rarely been reported. Here we attempt to define the epidemiological, clinical and radiological features of this unusual type of osteoarticular manifestation of BD. We retrospectively reviewed the medical records of 553 patients with Behçet's disease seen over 25-year period in our department of Internal Medicine (Sfax-Tunisia). All the patients fulfilled The International Study Group of Behçet's Disease criteria. Patients with destructive arthritis (defined by radiological changes: erosions and/or geodes and/or global narrowing of the joint space and/or ankylosis) were included in this study. Rheumatologic manifestations were observed in 71.1% patients. Eight patients (1.4% overall, 2% among patients with rheumatologic manifestations) had presented with destructive arthritis. The joint symptoms involved the knee in two cases, the wrist in one case, the elbow (one case), the sternoclavicular joint in two cases, the foot in one case and the tarsal scaphoïd in one case. There was recurrent arthritis at the same joint in the majority of cases. X-ray examinations revealed radiological changes: global narrowing of the joint in one case (knee), narrowing of the joint with geodes in three cases (knee, sternoclavicular), isolated geodes in two cases (tarsal scaphoid, foot) and severe lesions with ankylosis in two cases (two elbows, right wrist). Joint manifestations are common in patients with BD, but destructive arthritis is rare.

Clinical characteristics of Behçet's disease in China

To evaluate the prevalence of clinical findings in Behçet's disease (BD) in Chinese population. The clinical data of 170 consecutive BD patients were, retrospectively, analyzed and compared with previous reports. The mean age at onset was 34.4 years (range 6-72) and the mean age of diagnosis was 39.1 years (range 8-72). Mean delay in diagnosis was 5.7 years. The male to female ratio was 1.3:1. Recurrent aphthous ulceration (64.7%), skin lesion (18.2%), and genital ulceration (8.2%) were the commonest onset-presentations of the disease. During the disease course, the commonest presenting features were oral ulcer (100%), cutaneous involvement (68.2%), genital ulcer (63.5%), arthritis (37.1%), and ocular lesion (14.1%). As for the minor clinical manifestations, gastrointestinal lesion (10.0%), vascular lesion (8.8%), and cardiac lesion (4.7%) occurred occasionally. The pathergy skin test showed positive in 63.5% of the patients and revealed a higher positive rate in the females (76.7%) than in the males (53.6%). Less ocular lesion and genital ulcer were present in Chinese BD patients.

Macroscopic features of knee synovitis in early untreated Behçet disease and psoriatic arthritis

In a previous study, we found that synovial immunopathology differs between Behçet disease (BD) and psoriatic arthritis (PsA). The objective of this study is to describe the macroscopic features of early untreated knee synovitis in BD and PsA. Fourteen consecutive patients with active early knee synovitis (seven BD and seven PsA) undergoing rheumatologic arthroscopy were assessed. The following macroscopic synovial features were evaluated and scored by analyzing the video recordings of each procedure: capillary hyperaemia, morphology of synovitis, vascular pattern, fibrinoid membranes, and topographic distribution of these features. Video-recording of 35 early untreated arthritis patients with different diagnoses were also studied looking for BD-like macroscopic features. Six out of seven BD patients had extensive fibrinoid membranes and large areas of erythematous synovitis without villi or a distinctive vascular pattern, while PsA patients had diffuse erythematous villous synovitis with a tortuous vascular morphology. None of the 35 patients with early untreated arthritis exhibited all the characteristic features of BD synovitis. This exploratory study shows some distinctive features between BD and PsA knee synovitis that confirm macroscopic differences in patients with previously reported immunopathological differences.

Increased enthesopathy among Behçet's syndrome patients with acne and arthritis: an ultrasonography study

OBJECTIVE

Behçet's syndrome is characterized by clusters of disease expression, one of which is the coexistence of acne and arthritis. The aim of this study was to test the hypothesis that enthesopathy is increased in this cluster, having features reminiscent of acne-associated arthritis.

METHODS

The study group comprised 35 patients with Behçet's syndrome who had acne and arthritis (BS-AA), 38 patients with Behçet's syndrome who did not have arthritis (BS-WA), 37 patients with ankylosing spondylitis (AS), 25 patients with rheumatoid arthritis (RA), and 25 healthy control subjects. Five entheseal sites (the superior and inferior poles of the patella, the tibial tuberosity, and the superior and inferior poles of the calcaneus) on both lower extremities were examined by 2 independent observers, using ultrasonography. A previously validated composite score was calculated for each patient. The numbers of entheseal sites giving a positive power Doppler signal in each group were also compared.

RESULTS

Patients with AS had the highest enthesopathy score (mean +/- SD 4.1 +/- 2.4; F [4df] = 8.43, P < 0.001) followed by BS-AA patients (3.0 +/- 1.9; F [3df] = 3.63, P = 0.015). The mean +/- SD enthesopathy scores among the remaining 3 groups were similar (for BS-WA, 1.8 +/- 1.4; for RA, 2.2 +/- 1.6; for healthy controls, 2.0 +/- 1.5 [F (2df) = 0.65, P = 0.53]). Power Doppler scores were highest for the BS-AA group (mean +/- SD 3.0 +/- 1.5; F [4df] = 15.54, P < 0.001) followed by the AS group (2.7 +/- 1.8; F [3df] = 14.38, P < 0.001), the RA group (2.6 +/- 1.8; F [2df] = 13.88, P < 0.001), the BS-WA group (1.2 +/- 1.3; F [1df] = 4.48, P = 0.038), and the control group (0.5 +/- 1.1). There was 87% agreement between the 2 observers (kappa = 0.55, intraclass correlation coefficient 0.71).

CONCLUSION

The increased presence of enthesopathy among BS-AA patients compared with that among BS-WA patients further supports the hypothesis that patients with Behçet's syndrome who also have arthritis and acne form a distinct cluster.

Bone mineral density and bone turnover markers of patients with Behçet's disease

BACKGROUND

Behçet's disease (BD) is a systemic inflammatory disease of unknown aetiology. The pathogenesis of rheumatological findings and the status of bone metabolism in this disease are unknown. Inflammatory diseases may predispose to a decrease in bone mineral density (BMD) and there are many studies concerning osteoporosis in chronic inflammatory diseases.

OBJECTIVE

The aim of this study was to investigate BMD and bone turnover markers in patients with BD.

METHODS

Thirty BD patients (17 male and 13 female patients, mean age 36.9+/-12.6 years) and a total of 30 age- and sex-matched healthy controls (17 male and 13 female controls, mean age 34.9+/-8.95 years) recruited from the general population were enrolled in the study. Bone mineral density was measured at the lumbar spine (L1-4) and the left hip (total hip) using dual energy X-ray absorptiometry. Serum samples were collected between 8 and 10 am after overnight fasting. Serum calcium (Ca), phosphate (P), parathormone (PTH), total alkaline phosphatase (ALP), osteocalcin (OC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were measured. Free deoxypyridinoline cross-links (DPD) in second-void urine and total daily urinary calcium excretion were analysed.

RESULTS

No statistically significant difference in lumbar spine or femoral BMD and bone turnover markers were found between BD patients and control groups (P>0.05).

CONCLUSION

Although it is difficult to draw definite conclusions because of the limited number of patients involved, our study indicates that bone mineral density and bone turnover markers in Behçet's disease were no different than in healthy subjects.

The usefulness of Tc-99m-MDP bone scintigraphy in detection of articular involvement of Behçet's disease

Articular involvement was reported to be present in approximately 5-76% of Behçet patients. Therefore, we need a useful non-invasive method to detect articular involvement early in Behçet patients with nonspecific complaints. We aimed to evaluate the usefulness of 99mTc-methylene diphosphonate (Tc-99m-MDP) bone scintigraphy in the detection of the articular involvement of Behçet's disease (BD). Bone scintigraphy with Tc-99m-MDP was performed in 32 (17 male, 15 female) consecutive patients with BD. The sacroiliac (SI) joints with SI index higher than 1.34 were diagnosed as having sacroiliitis. Although joint complaints were present in only 8 (25%) patients, we detected joint involvement by scintigraphy in 27/32 (84.4%) Behçet patients mostly affecting the knees (62.5%), ankles (59.4%), SI joints (25%), wrists (21.9%), shoulders (18.7%), elbows (12.5%) and hips (3.1%). The articular involvement was monoarticular in four cases (12.5%) and was oligoarticular in the remaining. There was no correlation between joint involvement and age, gender, disease duration, drug usage or other clinical manifestations. Despite the fact that our patients were clinically asymptomatic and had normal pelvis radiography, sacroiliitis was found in 8 patients (25%). Bone scintigraphy is sensitive in the diagnosis of joint involvement allowing earlier diagnosis and showing the presence of articular involvement, especially in SI joints.

Decreased protein S activity is related to the disease activity of Behcet's disease

We wanted to see whether the active inflammation in Behcet's disease (BD) can cause a thrombotic disorder by decreasing the protein S (PS) activity, and we evaluated the relationship between the decreased PS activity and the disease activity of BD. We included 122 patients with BD whose PS activity levels were measured. In 51 patients, the PS activity was measured again when there were changes in the number of items of "The Behcet's Disease Current Activity Form (BDCAF)". The thrombosis rate was 2.5% (3/122), and the PS activity was low in all three of the patients with thrombosis. The incidence of low PS activity in the total 122 BD patients was 27% (33/122). The incidence of the low PS activity in the active BD patients was 33.7% (31/92), and this was significantly more frequent than in the inactive BD patients, (6.7%, 2/30) (chi(2)-test, P value = 0.0038). The decrease of PS activity had good correlation with the increase of the number of BDCAF items (r = -0.351, P value = 0.012). The PS activity decrease is related to the BD activity. The low PS activity can be the risk factor for thrombotic disorder and also the activity marker for BD and other inflammatory diseases.

[Behçet's disease in Tunisia. Clinical study of 519 cases]

PURPOSE

To describe clinical characteristics of Behçet's disease in Tunisia.

METHODS

It's a retrospective and multicentric study conducted by the Tunisian society of internal medicine. Inclusion criteria were those of the international study group. Were also included patients without international study group criteria but with at least one manifestation among arthritis, venous thrombosis or neurological manifestation with oral and genital ulceration or oral ulceration and skin lesions.

RESULTS

Five hundred and nineteen patients were included. 87.5% of them fulfilled the international criteria. The male to female ratio was 2,7. The mean age was 28.7+/-9.3 years at onset and 32.7+/-9.2 years at diagnosis. The incidence of each manifestations was as follows: oral ulcers: 100%, genital ulcers: 87.5%, pseudo-folliculitis: 67.6%, erythema nodosum: 17.5%, positive pathergy test: 51%, joint involvement: 55%, uveitis: 32.2%, vein thrombosis: 24.9%, arterial aneurysms: 3.9%, neurological involvement: 11.6%. The frequency of HLA B51 antigen was 35% among the 187 patients tested. There was no difference in the manifestations of the disease between patients having B51 and those lacking it. Venous thrombosis (29.8 vs 11.4%), arterial involvement (4.4 vs 1.4%) and uveitis (37.5 vs 17,9%) were significantly more frequent in men whereas erythema nodosum (22.9% vs 15.6%) and joint involvement (70,7 vs 49.9%) more frequent in women. The mean follow up was 6,1+/-5.7 years. Mortality rate was 2.3% in our series.

CONCLUSION

Our study confirms the androtropism of the disease in Mediterranean and Middle east countries. Positive pathergy test and venous thrombosis were more frequent in our study, like those from Mediterranean region. Whereas, ocular and neurological involvement were quite less frequent in our series.

The association between total antioxidant status and oxidative stress in Behçet’s disease

There has recently been growing evidence supporting the importance of oxidative stress in the pathogenesis of Behçet's disease (BD). In this study, we aim to evaluate total antioxidant status (TAS) and total oxidative stress (TOS) in BD patients, and compare their results both with controls that had recurrent aphthous stomatitis (RAS) and healthy controls. TAS statistically decreased in RAS patients, and TOS levels increased in BD and RAS patients than those in healthy controls. The serum levels of Cu significantly increased only in BD patients when compared with healthy controls. Fe levels were not statistically different among the BD patients, RAS patients and healthy controls, but there was a positive correlation between TOS and plasma Fe levels in BD patients. Our results suggest that there is an insufficient antioxidant system and increased oxidative status both in BD and RAS patients. The antioxidant supplementations in addition to medical treatments will improve the quality of life.

Arthropathy, quality of life, depression, and anxiety in Behcet's disease: relationship between arthritis and these factors

We aimed to determine arthritis frequency, quality of life (QoL), anxiety, and depression levels in Behcet's disease (BD) and thereby the effect of joint involvement on QoL, anxiety, and depression. Sixty-three patients diagnosed with BD according to the International Study Group Diagnostic Criteria and 45 healthy subjects as control were included in the study. All patients were evaluated in terms of clinical findings, the number and site of the joints involved, sacroiliac joint involvement, pain intensity, QoL, anxiety, and depression scale. The instruments used were Beck Depression Inventory (BDI) for depression, State-Trait Anxiety Inventory (STAI-T) for anxiety, and Health Assessment Questionnaire (HAQ) and Nottingham Health Profile (NHP) for health status and QoL. Joint involvement was seen in 41.3% of the patients. The most characteristic form was asymmetric oligoarthritis, which was seen in 65.3% of the patients. The joints most commonly involved were found to be in the wrist (53.8%) and knee (50%). Sacroiliitis was found at a rate of 38.1%. In BD patients without arthritis, rates of men (p=0.004) and genital ulcer (p=0.001) were higher, and rates of erythema nodosum (p=0.001) and human leukocyte antigen B5 positivity (p=0.023) were less than those of BD patients with arthritis. Pain intensity (p=0.000), NHP (p=0.004), and HAQ (p=0.003) scores were significantly higher in BD patients with arthritis than those without arthritis. Pain intensity, NHP, BDI, and STAI-T scores were significantly higher in BD patients without arthritis than in healthy controls, while pain intensity, NHP, HAQ, BDI, and STAI-T scores were significantly higher in BD patients with arthritis than in healthy controls (p=0.000). In conclusion, our study establishes that arthropathy is one of the common manifestations of BD. Arthritis in BD affects considerably patients' pain levels and QoL. A multistep approach is required for these patients. We are of the opinion that this approach may also improve the QoL of these patients and prevent the activation of the disease.

Extensive erosive arthropathy in a patient with Behçet’s disease: case report

Behçet's disease (BD) is a multisystem disease with typically nondeforming articular manifestations. Erosive arthropathy is an uncommon condition in patients with BD. We report herein an unusual case of long-standing BD with extensive erosive arthropathy radiologically mimicking psoriatic arthritis.

Synovial nitric oxide concentrations are increased and correlated with serum levels in patients with active Behçet's disease: a pilot study

Behçet's disease (BD) is a relapsing immunoinflammatory vasculitis of unknown etiology characterized by endothelial dysfunction. Articular symptoms and signs are present in about 75% of cases and characterized by seronegative arthritis and nonspecific synovitis. We demonstrated that both serum and erythrocyte nitric oxide (NO(.)) levels, the most abundant free radical in the body, were elevated in BD and associated with disease activity. This study further investigated NO(.) levels in the synovial fluid and serum from patients with active and inactive BD. A total of 23 BD patients with articular involvement (14 men and 9 women) satisfying International Study Group criteria and 15 age- and sex-matched healthy control subjects (9 men and 6 women) undergoing elective arthroscopy were included in this case-control investigation. The synovial fluid and serum were obtained from BD patients and controls. Clinical and laboratory findings including neutrophil count and erythrocyte sedimentation rate (ESR) were used to classify BD patients as active (n = 11) or inactive (n = 12). Synovial as well as serum NO(.) levels were compared between the groups and correlation analysis was performed. Acute phase reactant levels were significantly higher (for each, p < 0.01) in BD patients than control subjects in the active period. The mean synovial NO(.) level in active Behçet's patients (mean +/- SD 76.61 +/- 11.95 micromol/l) was significantly higher than in inactive patients (46.16 +/- 8.89 micromol/l, p < 0.001) and healthy control subjects (39.60 +/-8.03 micromol/l, p < 0.001). The difference between inactive patients and controls was not significant (p > 0.05). Active BD patients had significantly higher serum NO(.) levels (38.84 +/- 9.15 micromol/l) than inactive patients (30.91 +/- 5.88 micromol/l, p = 0.018) and control subjects (28.86 +/- 5.91 micromol/l, p = 0.002). In addition, synovial NO(.) levels were positively correlated with serum levels (r(2) = 0.621, p < 0.001). Increased synovial NO(.) levels in active BD patients probably reflect a nonspecific inflammatory process of the synovium and, therefore, arthralgia and arthritis as a common finding of BD.

Managing the symptoms of Behçet's disease

Behçet's disease (BD) is a chronic, relapsing, systemic inflammatory vasculitis of unknown aetiology with a myriad of immunological and pathological consequences. Patients with BD are clustered along the ancient silk road, extending from Far-East Asia to Turkey. The disease affects both genders of all ages from infants to the elderly. It is a long-term, cyclical disease and such patients may have symptom-free periods of weeks, months or years that are interrupted by exacerbations of varying intensities lasting a few days, weeks or months. Clinical features include oral aphthae, genital ulcers, ocular inflammation, skin lesions, as well as articular, vascular, neurological, pulmonary, gastrointestinal, renal and genitourinary manifestations. The main histopathological finding is a widespread vasculitis of the arteries and veins of any size or thrombophilia according to the site of involvement. BD may start with just one or two small symptoms but other symptoms may gradually appear over the years. Recurrent ocular inflammation, which occurs in approximately 50% of cases, is the major morbidity that may eventually lead to blindness. The treatment of BD is usually symptomatic and palliative. Therefore, the main objectives are to relieve symptoms associated with mucocutaneous lesions and arthritis, to modify the course of the disease, to control inflammatory eye disease, clinically suppress the inflammation and vasculitis, to prevent recurrences and thus, prevent irreversible damage. The choice of treatment is based on the severity of systemic involvement, clinical presentation and the site affected. The preferred treatment modalities are combined drug therapy and include topical therapies as well as systemic corticosteroids, NSAIDs, colchicine, dapsone and immunosuppressive and cytotoxic agents. Such therapies are tailored to the individual patient depending on clinical manifestations. Thalidomide, tacrolimus, IFN-alpha and anti-TNF monoclonal antibody have recently attracted attention as novel therapeutic approaches.

Erosive arthritis in a patient with Behçet's disease

We report on a 35-year-old female patient suffering from Behçet's disease for 20 years who developed recurrent oral ulcerations during the onset of the disease. This was followed by recurrent genital ulcerations and joint symptoms involving knee, wrist and feet joints and bilateral heel pain. X-rays of the feet revealed erosive and destructive changes in the 1st metatarsophalangeal and 1st proximal interphalangeal joints of the right foot and enthesopathy on calcaneus. A literature review indicated that erosive arthritis is a rare event in Behçet's disease.

Arthropathy in Behçet disease: MR imaging findings in two cases

Arthropathy is part of the protean manifestations of Behçet disease. Imaging findings reported thus far have been based on those of conventional radiography. Magnetic resonance imaging in two cases of Behçet disease with arthropathy demonstrated synovial thickening and effusion, as well as myositis manifested by high signal intensity on T2-weighted images.

Behçet's disease and sacroiliitis in a child

Abstract We describe the case of a Japanese girl who suffered from both Behçet's disease (BD) and bilateral sacroiliitis. This patient was diagnosed with BD at 8 years of age, and began to complain of buttock pain when she was 10 years old. X-rays of her pelvis showed bilateral grade 3 sacroiliitis, and bone scintigraphy showed an increased uptake in the sacroiliac joints. Movements of the spine and chest expansion were not restricted. HLA typing was positive for B44 and DR4, but negative for B27. The patient was not diagnosed as having seronegative spondyloarthropathy. This case indicates that erosive sacroiliitis is an intrinsic condition of BD.

Coagulation parameters and plasma total homocysteine levels in Behcet's disease

Behcet's disease (BD) is a multisystemic inflammatory disorder of unknown etiology that is sometimes associated with thrombosis in addition to systemic manifestations. However, the mechanism of hypercoagulability is not known. We evaluated the coagulation and fibrinolytic activities and the plasma total homocysteine levels of Korean BD patients in two cross-sectional studies. In the first study regarding coagulation and fibrinolytic activities, the levels of fibrinogen and von Willebrand factor (vWF) antigen were significantly higher in the BD patients than in the healthy controls (387.7+/-24.3 versus 240.6+/-8.8 mg/dl, p<0.001, and 131.9+/-8.8 versus 105.2+/-0.3%, p<0.01, respectively). The level of antithrombin III (AT III) was significantly lower in the BD patients (92.8+/-3.2 versus 106.3+/-2.6%, p<0.005). No differences were observed in the levels of plasminogen, protein C, or protein S activities. Activated protein C (APC) resistance was not observed in any BD patients. In the second study, the plasma total homocysteine levels of patients with a history of thrombosis (11.9+/-3.0 micromol/l) or disease activity (12.5+/-3.8 micromol/l) were found to be significantly higher than those of the controls (9.2+/-2.6 micromol/l, p<0.05, both). The plasma homocysteine concentrations in the thrombosis patients were positively correlated with plasma vWF levels; a relationship which suggests injury of the vascular endothelium (Spearman coefficient=0.857, p<0.01). Therefore, coagulation abnormality did not contribute to thrombotic complications, and higher levels of homocysteine may play a role in the hypercoagulablity of BD patients.

[Rheumatologic manifestations of Behcet's disease: report of 309 cases]

PURPOSE

To define the epidemiology and clinical features of Behçet's disease, giving special attention to unusual forms.

METHODS

We retrospectively reviewed the medical records of 309 cases with joint manifestations among 450 cases of Behçet's disease seen over a 20-year period who met the International Study Group of Behçet's disease criteria.

RESULTS

Joint manifestations were present in 68.3% and were inaugural in 34.5%. The knee and ankles were the joints most commonly affected. Monoarthritis, oligoarthritis and polyarthritis were seen respectively in 12, 13.5 and 19.8%. Sacroiliitis is observed in 6%. Unusual forms included destructive polyarthritis (two cases), popliteal cyst (two cases), myositis (two cases) and ankylosing spondylitis (two cases).

CONCLUSION

Joint manifestations are common in Behçet's disease. They are frequently associated with erythema nodosum and necrotic pseudofolliculitis. Polyarthritis is not rare. Their unusual forms deserve to be known.

Behçet's disease

Behçet's disease is a systemic vasculitis of unknown aetiology characteristically affecting venules. Onset is typically in young adults with recurrent oral and genital ulceration, uveitis, skin manifestations, arthritis, neurological involvement, and a tendency to thrombosis. It has a worldwide distribution but is prevalent in Japan, the Middle East, and some Mediterranean countries. International diagnostic criteria have been proposed, however diagnosis can be problematical, particularly if the typical ulcers are not obvious at presentation. Treatment is challenging, must be tailored to the pattern of organ involvement for each patient and often requires combination therapies.

Behçet's disease and complex aphthosis

Behçet's disease is a complex multisystem disease diagnosed by means of clinical criteria. Clinical features include oral and genital aphthae, pustular vasculitic cutaneous lesions, and ocular, gastrointestinal, and vascular manifestations. We believe that complex aphthosis, characterized by oral or oral and genital ulcers, may be a forme fruste of Behçet's disease. Although the pathogenesis of both Behçet's disease and complex aphthosis remain unknown, immune factors, infectious agents, and effector mechanisms are implicated. Treatment is based on the severity of systemic involvement and includes topical therapies as well as colchicine, dapsone, thalidomide, and immunosuppressive agents.

Clinical analysis of Behçet disease: arthritic manifestations in Behçet disease may present as seronegative rheumatoid arthritis or palindromic rheumatism

OBJECTIVES

To analyze arthritic manifestations in Behcet disease, which is one of the most common manifestations of Behcet disease.

METHODS

Among the patients who visited the Rheumatology Division, Keimyung University Dongsan Medical Center, Taegu, Korea from March 1997 to February 1998, 35 patients, with more than 3 months follow-up, were compatible for the diagnosis of Behcet disease according to the Shimizu criteria, after exclusion of uncertain or possible Behcet cases. The presence of various manifestations was evaluated. Regarding the joint manifestations, the involved joint, signs and the pattern of the articular symptoms were examined. Basic laboratory tests, HLA studies and simple radiologic studies were done.

RESULTS

All 35 patients had evident, recurrent, painful oral ulcers by the study definition. Genital ulcers were found in 29%, skin lesions in 77%, uveitis in 9%, gastrointestinal ulcerations in 6% and vascular manifestations in 6%. Joint manifestations appeared in 97%. Knee(91%), proximal interphalangeal (53%) and metacarpophalangeal joints(21%) were the main sites. Tenderness was prominent in 91% and swelling in 44%. Polyarticular presentation was found in 47%. In most cases (76.4%), the articular symptom was short-lasting. C-reactive protein was likely to be positive in active Behcet disease. HLA B51 was positive in 46%.

CONCLUSIONS

In Behcet disease, various manifestations can be found. The arthritic manifestation seems quite common. It may present as seronegative rheumatoid arthritis. Otherwise, it may present as palindromic rheumatism.
