VIRCHOW'S TRIAD

• Proposes that VTE occurs as a result of1.Alterations in blood flow (stasis)2.Vascular endothelial injury3.Alterations in the constituents of the blood

(inherited or acquired hypercoagulable state)

RISK FACTORS FOR VENOUS THROMBOSIS

• Inherited thrombophilia1. Factor V Leiden mutation2. Prothrombin gene

mutation3. Protein S deficiency4. Protein C deficiency5. Antithrombin (AT)

deficiency 6. Rare disorders

Dysfibrinogenemia

RISK FACTORS FOR VENOUS THROMBOSIS

• Acquired disorders1. Malignancy 2. Surgery, especially

orthopedic 3. Trauma 4. Pregnancy 5. Oral contraceptives 6. Immobilization 7. Antiphospholipid antibody

syndrome 8. Myeloproliferative

disorders – Polycythemia vera – Essential thrombocythemia

9) Presence of a central venous catheter

10) Congestive failure 11) Hormone replacement

therapy 12) Tamoxifen, Thalidomide,

Lenalidomide13) PNH14) IBD15) Nephrotic syndrome16) Behcet disease

SCREENING FOR HYPERCOAGULABLE STATE

• Screening for a hypercoagulable state is not generally recommended unless the results are likely to change subsequent therapy for the patient or family members

• There is currently no consensus regarding who to test for inherited thrombophilia

SCREENING FOR HYPERCOAGULABLE STATE

Only patients with one or more of the following:1.Initial thrombosis occurring prior to age 50 without an immediately identified risk factor (ie, idiopathic or unprovoked venous thrombosis)2.A family history of venous thromboembolism (ie, first-degree relatives with VTE prior to age 50)3.Recurrent venous thrombosis4.Thrombosis occurring in unusual vascular beds such as portal, hepatic, mesenteric, or cerebral veins5.A history of warfarin-induced skin necrosis, which suggests protein C deficiency

BEHCET’S DISEASE

DEFINITION

• Behcet's disease is a multisystem autoimmune disorder presenting with recurrent oral and genital ulcerations as well as ocular involvement.

EPIDEMIOLOGY

• Affects young males and females• Males and females are affected equally• Males often have more severe disease• Mediterranean region, the Middle East, and the

Far East• Prevalence ranges from 13.5 to 20 per 100,000• Prevalence in the United States and Europe have

ranged from 0.12 to 7.5 per 100,000

PATHOGENESISThe etiology and pathogenesis of this syndrome remain obscure•Increase of circulating autoantibodies – Anti-Enolase of endothelial cells– Anti-Selenium binding protein – Anti-Saccharomyces cerevisiae antibodies

•Association of Behcet's disease with HLA-B*5, HLA-B*51 and the MHC Class I region is confirmed•An association with ILI0 and the IL23R-ILI2RB2 locus were also observed•Perhaps infectious acts as a immune activity trigger

PATHOLOGY

The classic Behçet’s lesion is 1. Necrotizing leukocytoclastic obliterative

perivasculitis 2. Venous thrombosis 3. Lymphocytic infiltration of capillaries, veins and

arteries of all sizes• Cellular infiltration is often neutrophils and CD4+ T

lymphocytes

1.In some patients, diffuse inflammatory disease, involving all layers of large vessels and resulting to formation of pseudoaneurysms, suggests vasculitis of vasa vasorum.

CLINICAL FEATURES

Mucocutaneous1.The recurrent aphthous ulcerations– Are a sine qua non for the diagnosis – The ulcers are usually painful – Are shallow or deep with a central yellowish necrotic base – Appear singly or in crops – Are located anywhere in the oral cavity – Less than 10 mm in diameter are seen in 85% of patients,

while large or herpetiform lesions are less frequent– The ulcers persist for 1-2 weeks and subside without

leaving scars

CLINICAL FEATURES

2. The genital ulcers – Are less common but more specific – Painful – Do not affect the glans penis or urethra– Produce scrotal scars

3. Pseudofolliculitis 4. Erythema nodosum 5. Acne-like exanthem

CLINICAL FEATURESEye involvement•Occurring in 50% of patients•Is usually present at the onset but may also develop within the first few years•Includes

1. Anterior uveitis (Iritis )2. Posterior uveitis3. Bilateral pan uveitis with scarring

• Is the most dreaded complication, since it occasionally progresses rapidly to blindness.

– Retinal vessel occlusions– Optic neuritis

CLINICAL FEATURES

Articular involvement•Seen in a 50% of patients•Non-deforming arthritis or arthralgia•Affects knees and ankles

CLINICAL FEATURESVascular involvement 1.Venous involvement

– SVT or DVT is seen in 30% of patients– The superior vena cava is obstructed occasionally– Pulmonary emboli are a rare complication

2.Arterial involvement 1. Occurs in less than 5% of patients 2. Presents with

• Aortitis • Peripheral arterial aneurysm • Arterial thrombosis • Pulmonary artery vasculitis presenting with dyspnea, cough, chest

pain, hemoptysis, and infiltrates on chest roentgenograms has been reported in 5% of patients

• Behcet’s disease involve blood vessels of all sizes - small, medium, and large - both arteries and veins

CLINICAL FEATURES

Neurologic involvement •5-10%1.Mainly in the parenchymal form (80%) it is associated with brain stem involvement – IL-6 is persistently raised in CSF of these patients

•Dural sinus thrombi (20%) are associated with headache and increased ICP

CLINICAL FEATURES

Gastrointestinal involvement •Is seen more frequently in patients from Japan •Consists of mucosal ulcerations of the gut, resembling Crohn's disease

Genital tract involvement•Epididymitis is seen in 5% of patients

PATHERGY TEST

• Nonspecific skin inflammatory reactivity to any scratches or intradermal saline injection is a common and specific manifestation

• A papule or pustul 2 mm or more in size developing 24 to 48 hours after oblique insertion of a 20 to 25 gauge needle 5mm intra-demal, generally performed on the forearm

DIFFERENTIAL DIAGNOSIS• Differential diagnosis of recurrent oral ulcers includes – Herpes simplex – Benign aphthous ulcers – Inflammatory bowel disease – Stevens-Johnson syndrome– SLE – Dental prosthetics – Oral hygiene products– Medications such as methotrexate can cause oral ulcers – Pemphigoid, pemphigus vulgaris, cicatricial pemphigoid, – Lichen planus– Linear IgA disease

DIFFERENTIAL DIAGNOSIS

• Differential diagnosis of genital ulcers include:– HSV– Syphilis – Chancroid– Lymphogranuloma venereum– Fixed drug reactions – Neoplasms– Trauma

DIFFERENTIAL DIAGNOSIS• Other causes of inflammatory eye disease, neurologic

disease, vascular disease, arthritis, are included– SLE– IBD– Sarcoidosis – Reactive arthritis– Psoriatic arthritis– Ankylosing spondylitis– Juvenile idiopathic arthritis – FMF – MS– Tuberculosis – HIV– Malignancies

DIAGNOSIS

• Diagnosis is clinical and based on internationally agreed diagnostic criteria

• Recurrent oral ulceration plus two of the following:

1.Recurrent genital ulceration2.Eye lesions3.Skin lesions4.Pathergy test

LABORATORY FINDINGS

• Laboratory findings are mainly nonspecific indices of inflammation, such as

1.Leukocytosis 2.Elevated erythrocyte sedimentation rate3.Elevated C-reactive protein levels

TREATMENT

• Mucocutaneouce involvement1. Topical glucocorticoids (triamcinolone) in the form

of mouthwash or paste 2. Topical Sucralfate 1g/5mL four times daily as a

mouthwash3. Colchicine4. In more serious cases, Thalidomide (l00 mg/d)5. Prednisone starting dose is 15 mg/day, with

tapering to 10 mg/day after one week and discontinuation of prednisone entirely over two to three weeks period

TREATMENT

• Uveitis – Prednisone(I mg/kg per day) and azathioprine (2-3

mg/kg per day)

• Sight-threatening uveitis– Cyclosporin (5mg/kg) +/- azathioprine

• Panuveitis refractory or intolerant to other immunosuppressives– Anti-TNF therapy

TREATMENT

• Arthritis 1. Colchicine 1 to 2 mg/day, administered in

divided doses2. NSAIDs3. Prednisone 10 mg/day is an appropriate starting

dose• Joint complaints not controlled by colchicine

TREATMENT

• CNS-Behcet's syndrome – Prednisone(I mg/kg per day) and azathioprine (2-3

mg/kg per day)

PROGNOSIS• Behçet’s disease typically has a waxing and

waning course characterized by exacerbations and remissions

• The disease appears to be more severe in young, male, and Middle Eastern or Far Eastern patients

• The severity of the syndrome usually abates with time

• Apart from the patients with CNS-Behcet's syndrome and major vessel disease, the life expectancy seems to be normal and the only serious complication is blindness
