Behçet's disease in India: a clinical, immunological, immunogenetic and outcome study

Clinical profile and management with immunosuppressants and biologics in Behcet's uveitis: A cohort of 25 patients from a tertiary eye care center in South India

Purpose

To report the clinical profile of Behcet's disease and its management with immunosuppressants and biologics in a cohort of 25 patients from a tertiary eye care center in South India.

Methods

This was a retrospective, observational study. Records of 45 eyes of 25 patients between January 2016 and December 2021 were retrieved from the hospital database. Complete ophthalmic evaluation and systemic examination by the rheumatologist with appropriate investigations had been done. Results were analyzed using Statistical Package for the Social Sciences (SPSS) software.

Results

Males (19, 76%) were found to be more affected than females (6, 24%). Mean age of presentation was 27.68 ± 11.08 years. Twenty patients had bilateral involvement (80%), and unilateral involvement was seen in five patients (20%). Seven eyes of four patients (16%) had isolated anterior uveitis, out of which one patient had unilateral and three patients had bilateral involvement. Twenty-six eyes of 16 patients (64%) had posterior uveitis, out of which six patients had unilateral and 10 had bilateral involvement. Twelve eyes of seven patients (28%) had panuveitis, out of which two patients had unilateral and five had bilateral involvement. Hypopyon was seen in five eyes (11.1%) and posterior synechiae in seven eyes (15.55%). Posterior segment findings included vitritis (24.44%), vasculitis (17.78%), retinitis (17.78%), disc hyperemia (11.11%), and disc pallor (8.89%). Steroids alone were given in five patients (20%) and intravenous methylprednisolone (IVMP) was given in four patients (16%). Immunosuppressive agents along with steroids were given in 20 patients (80%), of which azathioprine alone was given in seven patients (28%), cyclosporin alone was given in two patients (8%), mycophenolate mofetil alone was given in three patients (12%), combination of azathioprine and cyclosporin was given in six patients (24%), and combination of methotrexate and mycophenolate mofetil was given in one patient (4%). Biologics were given in 10 patients (40%) - adalimumab in seven patients (28%) and infliximab in three patients (12%).

Conclusion

Behcet's disease is an uncommon uveitis in India. Addition of immunosuppressants and biologics to conventional steroid therapy gives better visual outcomes.

Behcet's disease in an adult male from Nepal: A case report

This case report highlights considering Behcet's disease as a diagnosis in orogenital ulcers and uveitis, although its prevalence is unknown in Nepal due to underreporting. Also, collaboration for patient care among relevant specialties is required.

Behcet disease - A nonvenereal cause of genital ulceration

Behcet's disease (BD) is a chronic, relapsing, inflammatory vascular disease with no diagnostic or pathognomonic test. Here, we present a case of 26-year-old male with a complaint of recurrent oral, genital, and cutaneous lesions. The diagnosis of BD was confirmed on the basis of revised the International Criteria for BD. The case was treated satisfactorily with systemic corticosteroid in the tapering dose and oral Dapsone.

Surprise of Behcet’s disease in a patient with bilateral disc oedema and the role of OCT

Behcet’s disease is a multisystem vasculitis which can be associated with cerebral venous thrombosis (CVT) leading to increased intracranial tension and papilloedema. We report a case of a 17-year-old boy who presented to us with inward deviation of right eye with bilateral disc oedema and on further investigations was found to be Human Leukocyte Antigen (HLA) B5 positive, along with CVT on magnetic resonance venography which further led us to the diagnosis of non-parenchymal neuro-Behcet’s.

Poor prognostic factors in patients with newly diagnosed intestinal Adamantiades-Behçet's disease in the Shanghai Adamantiades-Behçet's disease database: a prospective cohort study

BACKGROUND

Adamantiades-Behçet's Disease (ABD) is an immunological recurrent systemic vasculitis with a chronic course. We investigated the predictors of long-term flare-ups, poor outcomes and event-free survival in Chinese non-surgical patients with intestinal ABD.

METHODS

This was a prospective cohort study of 109 intestinal ABD patients seen in our institution between October 2012 and January 2019 who met the international criteria for ABD and had intestinal ulcers confirmed on colonoscopy. Predictors of relapses and poor outcomes, event-free survival were calculated using logistic regression models and Cox proportional hazard regression models, respectively.

RESULTS

Sixty-six intestinal ABD patients (60.55%) had ileocecal ulcers; 19 patients (17.43%) presented with colorectum ulcers; 24 patients (22.02%) showed both ileocecal and colorectum ulcers. 7 patients (6.42%) experienced at least 1 flare-up of intestinal ulcers. 38 patients (34.86%) complained of non-healing intestinal ulcers. In multivariate analysis, location of intestinal ulcers (ileocecal and colorectum) (odd ratio (OR) 7.498 [95% confidence interval [95% CI] 1.844-30.480]), erythrocyte sedimentation rate (ESR) > 24 mm/h (OR 5.966 [95% CI 1.734-20.528]), treatment with infliximab (IFX) (OR 0.130 [95% CI 0.024-0.715]), and poor compliance (OR 11.730 [95% CI 2.341-58.781]) were independently correlated with a poor outcome. After a median follow-up of 28 months, 45 intestinal ABD patients (41.28%) underwent adverse events. Factors independently associated with shorter event-free survival were early onset of ABD (< 7 years) (hazard ratio (HR) 2.431 [95% CI 1.240-4.764]) and poor compliance (HR 3.058 [95% CI 1.612-5.800]).

CONCLUSION

Distribution of intestinal ulcers (ileocecal and colorectum), ESR > 24 mm/h, treatment without IFX, and poor compliance were independent risk factors for poor outcomes in non-surgical intestinal ABD patients.

Behcet's disease in Iran: Analysis of 7641 cases

Objective: To analyze Behcet's Disease (BD) in Iran, from 1975 to 2018, and compare to 35 large/small reports from other countries.Methods: Patients from all over Iran, when suspected, were sent to the BD Unit. The diagnosis was done by expert opinion. All data were recorded in the BD registry (updated in each follow-up). The data are given in percentage with 95% confidence Intervals.Results: The mean age at onset was 25.6 years. Standard deviation (SD) was 9.8. The mean disease duration was 11.7 years (SD: 8.9). Males were 55.8% (54.7-56.9), Females 44.2% (43.1-45.3), Oral Aphthosis (OA) 97.5% (97.1-97.9), genital aphthosis (GA) 64.4% (63.3-65.5), skin lesions 62.2% (61.1-63.3), ocular lesions 55.6% (54.5-56.7), Joint Manifestations 38.1% (37.0-39.2), Gastrointestinal 6.8% (6.2-7.4), Vascular 8.9% (8.3-9.5), neurological (central-peripheral) 3.9% (3.5-4.3), epididymitis 4.6% (4.1-5.1). Lab tests were positive pathergy test 50.4% (49.3-51.5), elevated ESR 51.1% (50.0-52.2), abnormal urinalysis 13.4% (12.6-14.2). The International Study Group (ISG, 1990) criteria and the International Criteria for Behcet's Disease (ICBD, 2014) had respectively a sensitivity of 76.2% (75.2-77.2) and 96.6% (96.2-97.0). The specificity was 99.3% (99.1-99.5) and 97.3% (96.9-97.7). The accuracy was 86.4% (85.8-87.0) and 96.9% (96.6-97.2).Conclusion: The most frequent manifestations were OA, GA, skin manifestations, and ocular manifestations.

Noninfectious uveitis in the Asia-Pacific region

Uveitis is a sight-threatening disease. Up to 35% of patients may have impaired vision. Inflammation of the uvea tissue has more than 60 etiologies. Previous reports have shown that 20-40% of uveitis cases were noninfectious. Some of them may be associated with systemic rheumatological and autoimmune diseases but some may affect the eyes only. The epidemiology and clinical situations of some specific uveitis entities vary worldwide because they are influenced by genetic, ethnic, environmental, and socioeconomic factors. The Asia-Pacific region comprises more than 30 countries. Epidemiology and patterns of uveitis vary greatly in this region. However, some uveitis entities, such as Behcet's disease, sarcoidosis, and Vogt-Koyanagi-Harada disease, are more common in this region. Many studies on the epidemiology, risk factors, and immune pathogenesis of this disease have been conducted. In this article, we review the epidemiology of noninfectious uveitis and special situations of these three uveitis entities in the Asia-Pacific region.

Severe panuveitis in neuro-Behçet's disease in Malaysia: a case series

Behçet’s disease (BD) is a multisystemic disease that is very rare in Malaysia. About 5% of patients develop central nervous system involvement, termed neuro-Behçet’s. Neuro-Behçet’s is one of the most serious causes of long-term morbidity and mortality. We report two cases of neuro-Behçet’s associated with uveitis (ocular BD) highlighting the clinical presentation, diagnostic measurement, and therapeutic management of these cases.

Behçet’s Disease: A Review

Behçet’s disease (BD) is a multi-system inflammatory disorder dominated clinically by recurrent oral and genital ulceration, uveitis, and erythema nodosum. Behçet’s disease runs a chronic course, with unpredictable exacerbations and remissions whose frequency and severity may diminish with time. Behçet’s disease typically arises in young adults, although childhood-onset BD has also been reported. The disease can affect both genders and has a worldwide distribution, although it is more prevalent in countries of the ancient Silk Route. The cause of BD remains unknown, although an autoimmune reaction triggered by an infectious agent in a genetically predisposed individual has been suggested. The treatment of BD is symptomatic and empirical, but generally specific to the clinical features of each patient. The majority of affected individuals do not have life-threatening disease, although mortality can be associated with vascular-thrombotic and neurological disease.

Nodular scleritis as the eye manifestation in Behcet's syndrome

We report a case of a 45-year-old female, who was diagnosed as Behcet's disease and presented to us with nodular scleritis in her right eye.

Genital aphthosis in Behçet's disease: is it associated with less eye involvement?

Behçet's disease (BD) is a multisystem disease classified among the vasculitides with various clinical features. Genital aphthosis (GA) is one of the major manifestations of BD. The aim of this study was to evaluate the characteristics of BD patients with GA. A cross-sectional sample of BD patients registered in 37 years was selected. We determined clinical and laboratory features of BD patients with GA (GA cases) and compared them with the patients who never developed GA (non-GA cases). The comparisons were performed by the chi-square test and logistic regression analysis. Odds ratios (ORs) with 95 % confidence intervals were calculated to estimate the precision of ORs. Among 6,935 BD patients, 4,489 cases (64.7 %) were ascribed to GA cases. Male to female ratio (1.11:1.00 vs. 1.48:1.00 OR 0.753, P value <0.001) and mean age of disease onset (OR = 0.9, P value <0.001) were lower in GA subset. In GA cases, oral aphthosis (OA) was a more common onset manifestation (OR 2.250, P value <0.001), while uveitis (OR 0.140, P value <0.001) and retinal vasculitis (OR 0.077, P value <0.001) were less common at the disease onset. In the whole course of disease, eye involvement was less common in GA cases (OR 0.215, P value <0.001). On the contrary, OA (OR 19.698, P value <0.001), skin (OR 1.762, P value <0.001), joint (OR 1.257, P value = 0.001), gastrointestinal (OR 1.302, P value = 0.009), neurological (OR 1.624, P value <0.001) and vascular involvements (OR 1.362, P value <0.001), epididymitis (OR 1.596, P value <0.001), positive pathergy test (OR 1.209, P value <0.001) and positive familial history of OA (OR 1.325, P value <0.001) were more common in GA subset. This study showed that GA subset of BD is associated with less eye involvement but higher rates of other BD manifestations.

Right hilar mass with hemoptysis: An unusual presentation of uncommon disorder

Common differential diagnosis of lung and hilar opacity includes infectious pathology or a mitotic lesion. Behcet's disease (BD) is a rarely diagnosed disease in Indian subcontinent. BD is a multisystem inflammatory disorder that presents with recurrent orogenital ulceration, uveitis, and erythema nodosum. We present here the case of a patient who presented with recurrent hemoptysis with radiological picture of hilar mass, during the evaluation of which the diagnosis of BD was established.

Behcet's disease: from East to West

Behcet's disease (BD) is classified among vasculitides. There are actually five nationwide surveys of BD: Iran, Japan, China, Korea, and Germany. Among case series, four are on more than 200 cases (Turkey, Morocco, Tunisia, and UK). BD was classically seen around the Silk Route. Now, it is seen everywhere. The male to female ratios were, respectively (in nationwide surveys), 1.19, 0.98, 1.34, 0.63, and 1.40 to 1. The mean age at onset was 26.2, 35.7, 33.8, 29, and 26 years. Major manifestations were seen, respectively, in nationwide surveys: mucous membrane (oral aphthosis in 97%, 98%, 98%, 99%, and 98%; genital aphthosis in 65%, 73%, 76%, 83%, and 64%); skin manifestations (pseudo-folliculitis in 57%, N/A, 31%, N/A, and 62%; erythema nodosum in 22%, N/A, 38%, N/A, and 42%; ocular manifestations in 55%, 69%, 35%, 51%, and 53%). Minor manifestations were seen, respectively, in nationwide surveys: joint manifestations in 33%, 57%, 30%, 38%, and 53%; neurological manifestations in 9%, 11%, 6.5%, 4.6%, and 11%; gastrointestinal manifestations in 7%, 15.5%, 9%, 7.3%, and 12%; vascular involvement in 8.9%, 8.9%, 7.7%, 1.8%, and 13%; pulmonary manifestations in 0.3%, N/A, 2.2%, N/A, and 3.6%; cardiac manifestations in 0.5%, N/A, 4%, N/A, and 3.2%. Laboratory tests are not useful except the pathergy test, which was positive in 54%, 44%, N/A, 40%, and 34% of cases. ESR was normal in many patients. Diagnosis is based upon clinical manifestations. The International Criteria for Behcet's Disease (ICBD, 2006) may be of help, having a sensitivity of 98.2% and a specificity of 95.6% in Iranian patients.

Current trends in the management of ocular symptoms in Adamantiades-Behçet's disease

Adamantiades-Behçet’s disease (ABD) is a multisystemic vasculitic disease. It is most prevalent in the Eastern Mediterranean countries and the Eastern region of Asia. Its effect on the eye can range from mild to debilitating, resulting in total blindness. A necrotizing and obliterative vasculitis affects both arteries and veins of organs. Recurrent attacks of uveitis, oral aphthous ulcers, skin lesions, and genital ulcers are common. Topical and systemic corticosteroids have been the mainstay in the treatment of ocular inflammation for many years; however, due to the several known side effects of corticosteroids and thanks to scientific advances, more novel approaches to ABD treatment have been emerging. Antimetabolites such as methotrexate and azathioprine have been utilized with the latter showing positive results. Chlorambucil has been utilized effectively for ocular manifestations of ABD. Interferon alpha has shown encouraging results in the management of refractory ocular inflammation associated with ABD, either alone or in combination with other immunosuppressive agents. Surgical interventions to deal with complications from ABD can be safely done if adequate control of inflammation is achieved peri-operatively. Early detection and aggressive treatment, when needed, have proven to be essential in the management of this relentlessly explosive disease.

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.

[Skeletal manifestations in Behçet's disease. A report of 79 cases]

PURPOSE

Our aim is to describe the skeletal manifestations of Behcet's disease (BD) among young adults in a military population.

METHODS

We conducted a retrospective study of 176 patients with BD who were followed between 1980 and 2005. All the patients fulfilled the international study group on Behcet's disease diagnostic criteria.

RESULTS

Rheumatic manifestations were noticed in 79 out of 176 patients (45%), ranking second after the skin and mucosal manifestations of the disease. Articular manifestations were the first disease manifestation in 16.5% of the patients. Inflammatory arthralgias were the most common manifestation and observed in 81%, interesting mainly the large lower limb joints. Disease course was acute in most of the patients. Arthritis was less common: oligoarthritis (7.5%), monoarthritis (6.5%) and polyarthritis (5%). Axial involvement was also noted: spine pain in 29%, isolated sacroiliitis in 7.5%, and definite ankylosing spondylitis in 5%.

CONCLUSION

Joint involvement is common in BD and could be the first manifestation of the disease. Most of the patients present with inflammatory arthralgias of the large lower limb joints. Disease course is usually favourable, spontaneously or with treatment. However, in our study population, skeletal manifestations were responsible for significant disability.

[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.

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.

Pulmonary vasculitis in behcet disease: a cumulative analysis

STUDY OBJECTIVES

The aims of this study were to investigate the frequency of pulmonary problems in Behçet disease (BD), and to discuss lesser-known features of pulmonary BD such as clinical characteristics, analysis of prognosis, and evaluation of treatment options with respect to the previously published cases.

DESIGN

We conducted a comprehensive review of the literature to analyze cumulated data about pulmonary involvement in BD.

SETTING

We found 159 articles regarding pulmonary disease associated with BD in May 2003.

PATIENTS

The evaluation of these articles demonstrated 598 pulmonary problems in 585 cases.

RESULTS

Pulmonary artery aneurysms (PAAs) are the most common pulmonary lesion in BD, and these are almost always associated with hemoptysis. Seventy-eight percent of patients with aneurysms have concomitant extrapulmonary venous thrombi or thrombophlebitis. Other pulmonary problems are reported in BD, and these are principally related to vascular lesions and radiologic abnormalities.

CONCLUSIONS

Pulmonary vascular problems, either PAA or involvement of small-sized vessels, are the main pulmonary disorders in BD. Immunopathologic findings indicate that the underlying pathogenesis is pulmonary vasculitis, which may result in thrombosis, infarction, hemorrhage, and PAA formation. Patients with small nonspecific radiologic abnormalities should be followed up closely since early diagnosis of vascular lesions may be life-saving. Immunosuppression is the main therapy for the treatment of a vasculitis. It is important that pulmonary angiitis is not mistaken for pulmonary thromboembolic disease since fatalities have occurred in BD shortly after initiation of anticoagulation/thrombolytic treatment.

Behçet's syndrome with pyoderma-gangrenosum-like lesions treated successfully with dapsone monotherapy

Behçet's syndrome (BS) is a rare multisystem disorder belonging to a group of neutrophilic dermatoses. We report a 65-year-old male patient who had suffered from recurrent painful orogenital ulcers for 50 years from the age of 15 and started developing pustular and bullous lesions evolving into non-healing ulcers similar to those seen in pyoderma gangrenosum (PG) two months prior to presenting to us. There was no evidence of systemic disease or malignancy. Routine baseline investigations were within normal limits. The patient was treated successfully with dapsone, antibiotics, and local wound care.

[Neurologic manifestations of Behcet's disease: analysis of a series of 27 patients]

PURPOSE

To describe epidemiological and clinical characteristics of neurological involvement in Behçet's disease (BD) and to determine a subgroup of patients at high risk for this complication.

PATIENTS AND METHODS

The medical notes of 105 patients with BD fulfilling the criteria of the international Study Group for Behçet's disease were retrospectively reviewed. Patients were divided into two groups according to the presence (group 1) or not (group 2) of neurological and/or psychiatric involvement attributable to BD. The epidemiological, clinical and genetic (HLA B51 and MICA 6 frequency) features in the two groups were analysed and compared using the Kruskall-Wallis and the chi-square tests.

RESULTS

Twenty-seven patients (25.7%) had clinical evidence of neurological involvement. They were 20 men and 7 women. The mean age at neurological onset was 34.26 +/- 8.79 years. Nineteen patients (70.3%) had meningoparenchymal "MP" central nervous system involvement (brainstem: 9, hemispheric involvement: 6, spinal cord: 4, psychiatric involvement: 2, isolated pyramidal signs: 1, aseptic meningitis: 1). Seven patients (25.9%) had cerebral large vessels involvement that is cerebral angio-Behçet "CAB" (intracranial hypertension: 5 cases due to cerebral venous thrombosis: 3 and pseudotumor cerebri: 2, cerebral haemorrhage: 1, cerebral arterial thrombosis: 1). One patient (3.7%) had both "MP" and "CAB" involvement. Headache was significantly more frequent in non-parenchymal patients. In group 1, complete recovery or improvement with mild neurological impairment was seen in 13 cases, improvement with severe disability in 3 cases, worsening in 1 case, the course was stationary in 1 case and 3 patients died (11.2%). Arterial aneurysms were significantly more frequent in "CAB" subgroups than in subgroup 2.

CONCLUSION

Frequency of neurological involvements in BD was high in our study. Arterial aneurysms seem to be a risk factor to these complications. Cerebral angio-Behçet appears to be a protector factor against uveitis.

Renal Behçet's disease: a cumulative analysis

OBJECTIVE

To analyze cumulated data about renal involvement in Behçet's disease (BD) and to report on 6 patients with BD and renal problems.

METHODS

We found reports of 159 patients (including our patients) with BD and specific renal disease (amyloidosis 69, glomerulonephritis [GN] 51, renal vascular disease 35, and interstitial nephritis 4) in our survey.

RESULTS

The frequency of renal problems among BD patients has been reported to vary between 0% to 55%. Male gender is a risk factor for all types of renal BD. Nephrotic syndrome was present in 83% of patients with amyloidosis, and renal failure was common at the time of diagnosis. The mean interval between the initial manifestation of BD and diagnosis of amyloidosis was shorter in men than in women (P =.02). AA-type amyloid fibrils were shown in all cases studied. Vascular involvement was common in the patients with amyloidosis (60%). The renal findings in GN show a wide spectrum, from asymptomatic hematuria and/or proteinuria to rapidly progressive GN. Several types of glomerular lesions ranging from minor glomerular changes to crescentic glomerulonephritis are observed in BD. The common types of glomerular lesions among the reported cases are crescentic GN, proliferative GN, and immunoglobulin A (IgA) nephritis. Aneurysms may be located throughout the renal artery, from the orifice of the main artery to intrarenal microaneurysms. Another type of renal disease (amyloidosis or GN) and other major vascular involvement were present in all cases with renal vein thrombosis. Hypertension is common among patients with renal artery aneurysm or stenosis. Microscopic vascular disease was described in 4 patients.

CONCLUSIONS

Based on data in the literature, we suggest that renal involvement in BD is more frequent than has been recognized, although it is most often mild in nature. Amyloidosis is one of the prognostic factors affecting survival. Patients with vascular involvement carry high risk for amyloidosis, and administration of colchicine to these patients may be beneficial. More evidence is needed to accept interstitial nephritis as a manifestation of BD. In spite of some difficulties, hemodialysis and renal transplantation are safe treatment options in BD-related uremia.

Gastrointestinal manifestations of Behcet's disease

Behcet's disease (BD) is a multisystem, chronic, relapsing vasculitis of unknown origin that affects nearly all organs and systems. While recurrent oral ulcerations are a "sine qua non" of BD, the frequency of extra-oral parts of the gastrointestinal involvement varies widely in different countries. The most frequent extra-oral sites of gastrointestinal involvement are the ileocecal region and the colon. The liver (except with Budd-Chiari syndrome), pancreas, and spleen are rarely involved. The symptoms associated with these extra-oral manifestations of BD are abdominal pain, nausea, vomiting, diarrhea with or without blood, and constipation. The lesions typically are resistant to medical treatment and frequently recur with surgical treatment. We review the literature regarding the gastrointestinal and hepatobiliary systems in BD. Also, we present a patient who had BD complicated with radiologically-proven hepatic veins involvement (Budd-Chiari syndrome) and complete occlusion of hepatic portion of inferior vena cava and who had a good response to colchicine and penicillin treatment.

Recurrent epididymo-orchitis in patients with Behçet's disease

PURPOSE

We study the clinical features of epididymo-orchitis in patients with Behçet's disease.

MATERIALS AND METHODS

Of 57 men with Behçet's disease 7 had epididymo-orchitis during the course of disease. A questionnaire was applied to all cases and the clinical features were recorded. HLA class 1 was determined and a pathergy test was performed.

RESULTS

All 7 patients fulfilled the international study group criteria for Behçet's disease. All patients had recurrent oral ulcers, skin lesions (folliculitis, erythema nodosum-like lesions) and uveitis, and 6 had recurrent genital ulcers, 2 arthritis, 1 vasculitis and 4 central nervous system involvement. The pathergy test was positive in 4 patients and all had B5(51). The allele B5101 was present in 6 patients and 1 had B5102. Recurrences were observed in 5 patients. Concurrent symptoms with epididymo-orchitis consisted of oral ulcers, fever, uveitis, arthritis and penile ulcer. Colchicine, glucocorticoids, nonsteroidal anti-inflammatory drugs and cyclosporine were administered.

CONCLUSIONS

Epididymo-orchitis in patients with Behçet's disease is not as infrequent as believed. It was not the first manifestation of the disease but developed during followup. In any patient with epididymo-orchitis Behçet's disease should be considered, particularly in regions with a high prevalence of the disease.

The Bath Ankylosing Spondylitis Radiology Index (BASRI): a new, validated approach to disease assessment

OBJECTIVE

To develop a reproducible and simple radiologic scoring system for the spine in patients with ankylosing spondylitis (AS): the Bath Ankylosing Spondylitis Radiology Index for the spine (BASRI-s).

METHODS

Radiographs of 470 patients with AS were scored using the New York criteria for the sacroiliac joints and, similarly, grading the lumbar and cervical spine on a scale of 0-4 (for normal, suspicious, mild, moderate, and severe). These 3 scores were added together to produce the BASRI-s score (scored 2-12). Radiographs of 188 patients were used to test reproducibility. Blinded radiographs of 89 non-AS patients were included, randomly, to assess disease specificity. Sensitivity to change was assessed using 177 radiographs from 58 AS patients.

RESULTS

Intra- and interobserver variation showed 75-86% and 73-79% complete agreement at all sites, respectively. Specificities of 0.83-0.89 suggested that the lumbar and cervical spine BASRI scores were disease specific. Sensitivity to change became apparent at 2 years (P < 0.001). Using a lateral view and an anteroposterior view of the lumbar spine was more sensitive than using a lateral view alone. Grading a set of radiographs (sacroiliac joints, lumbar spine, and cervical spine) took 30 seconds.

CONCLUSION

BASRI is a reliable method for grading radiographic changes in patients with AS. It is disease specific, sensitive to change, valid, simple, and rapid to perform.
