Abstract
Behçet disease (BD) is a chronic, relapsing, systemic vasculitis of unknown etiology with the clinical features of oral and genital ulcers, cutaneous vasculitic lesions, ocular, articular, vascular, gastrointestinal, neurologic, urogenital and cardiac involvement. BD usually appears around the third or fourth decade of life. Gender distribution is roughly equal. The disease is much more frequent in populations along the ancient 'Silk Road', extending from Eastern Asia to countries in the Middle East and the Mediterranean, compared with Western countries, but has universal distribution. Mucocutaneous manifestations are the clinical hallmarks of BD. The diagnostic criteria widely used in the disease's diagnosis are based on mucocutaneous manifestations because of their high sensitivity and/or specificity. Genetic factors are the key driver of BD pathogenesis, and HLA-B51 antigen is the strongest genetic susceptibility factor. Streptococcus sanguinis (S. sanguinis) or microbiome change can trigger innate immune system-mediated inflammation sustained by adaptive immune responses. Epistatic interaction between HLA-B51 and endoplasmic reticulum aminopeptidase 1 (ERAP1) in antigen-presenting cells disrupt T-cell homeostasis leading to downregulation of Tregs and expansion of Th1 and Th17. Thus, neutrophil activation and intense neutrophil infiltration of the affected organs develop in the early stage of inflammation. BD has a variable clinical course with unpredictable exacerbations and remissions. The disease is associated with a high mortality rate, especially in young male patients, and large-vessel, neurological, gastrointestinal system and cardiac involvement are the most important causes of death. The principal aim of treatment should be to prevent irreversible organ damage, especially during the disease's early, active phase. A better understanding of the disease's pathogenesis has provided important information on its management. New drugs, especially apremilast and anti-TNF-α agents are effective in the management of BD and have the potential to improve patients' quality of life, prognosis and survival.

[PMID: 32622799 DOI: 10.1016/j.oooo.2020.06.009] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 05/13/2020] [Accepted: 06/04/2020] [Indexed: 10/24/2022]
Abstract
OBJECTIVE Thalidomide is an effective systemic agent in the management of ulcerative oromucosal conditions. However, its clinical use is limited because of its known adverse effect profile, including teratogenicity, peripheral neuropathy, and thromboembolic risk. The aim of this study was to review the efficacy and safety of thalidomide over a 10-year period in an Oral Medicine specialty clinic. STUDY DESIGN Clinical records of the Oral Medicine Department at the Royal National ENT and Eastman Dental Hospitals (London, UK) were retrospectively reviewed for patients prescribed thalidomide between 2009 and 2019 for the management of oromucosal ulceration. Twelve eligible patients were identified. Data on patient response to treatment and major/minor adverse events were obtained from their clinical and electrophysiologic records. RESULTS A complete remission rate was noted in 50% (6 of 12) patients treated for recurrent aphthous stomatitis, HIV-related ulceration and oral Crohn disease. A thalidomide-induced neuropathy rate of 41.7% (5 of 12) was detected by electrophysiology testing, however clinical symptoms of neuropathy were only described by 3 subjects. No other major adverse effects were reported. CONCLUSIONS Thalidomide demonstrates a good efficacy-to-safety ratio in the management of oromucosal ulceration over a prolonged treatment period. Interval electrophysiologic testing is essential to monitor for thalidomide-induced neuropathy. In this cohort, neuropathy does not appear to be a dose-dependent outcome.

Abstract
Behçet's disease (BD) is a multisystemic disorder of unknown etiology mainly defined by recurrent oral aphthosis, genital ulcers, and chronic relapsing bilateral uveitis, all of which represent the "stigmata" of disease. However, many other organs including the vascular, neurological, musculoskeletal, and gastrointestinal systems can be affected. The gastrointestinal involvement in Behçet's disease (GIBD), along with the neurological and vascular ones, represents the most feared clinical manifestation of BD and shares many symptoms with inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis. Consequently, the differential diagnosis is often a daunting task, albeit the presence of typical endoscopic and pathologic findings may be a valuable aid to the exact diagnosis. To date, there are no standardized medical treatments for GIBD; therefore therapy should be tailored to the single patient and based on the severity of the clinical features and their complications. This work provides a digest of all current experience and evidence about pharmacological agents suggested by the medical literature as having a potential role for managing the dreadful features of GIBD.

Abstract
Behçet's disease (BD) is a multisystemic disorder of unknown etiology characterized by the "triple symptom complex" consisting of recurrent oral aphthosis, genital ulcers, and chronic relapsing bilateral uveitis. Recurrent mucocutaneous lesions are generally considered the hallmark of the disease, being the most common symptoms presenting at the onset of disease. Although the improvement of knowledge about the pathogenetic mechanism added important changes in the treatment management of BD clinical manifestations, thus avoiding the appearance of serious life-threatening complications which are disease related, the mucocutaneous lesions are still the most nagging clinical manifestations to be treated. In this work we reviewed the current state of knowledge regarding the therapeutic approaches for mucocutaneous lesions of BD mainly based on controlled studies to provide a rational framework for selecting the appropriate therapy for treating these troublesome features of the disease.

Abstract
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.

Abstract
Thalidomide is approved for treating erythema nodosum leprosum and multiple myeloma, but it has also emerged as a useful treatment option for many refractory dermatologic disorders. Some of the innovative but off-label uses of thalidomide include aphthous stomatitis, Behçet's disease, lupus erythematosus, prurigo nodularis, sarcoidosis, actinic prurigo, graft-versus-host disease, Langerhans cell histiocytosis, erythema multiforme, lichen planus, Kaposi sarcoma, Jessner lymphocytic infiltrate, uremic pruritus, pyoderma gangrenosum, scleroderma, scleromyxedema, and necrobiosis lipoidica. This article reviews the background, pharmacology, and innovative uses of thalidomide in dermatology.

Abstract
Severe recurrent aphthous stomatitis (SRAS) is a rare, disabling disorder of unknown etiology. Thalidomide is an effective second-line therapy for SRAS, but is suppressive rather than curative, and adverse events limit its use. Few reports describe the efficacy, tolerance, and safety of thalidomide, and how it is actually used as long-term (maintenance) therapy for SRAS. Therefore, we conducted this study to describe thalidomide use in the real-life management of a cohort of patients with SRAS. This multicenter retrospective cohort study covered a period of 5 years and 5 months (January 2003-May 2008). Patients who had started thalidomide monotherapy for SRAS during the 2003-2006 period were eligible. Data were collected from patients' medical charts and supplemented by patients' responses during a targeted telephone interview. Ninety-two patients followed at 14 centers were included: 76 had oral or bipolar aphthosis, and 16 had Behçet disease. Thalidomide was rapidly effective: 85% (78/92) entered complete remission (CR) within a median of 14 days. Response time was independent of the initial thalidomide dose (r = 0.04). Thalidomide was continued for > or =3 months (maintenance therapy) by 77/92 (84%) of the patients on 1 of 2 maintenance regimens: continuous therapy with regular intake (60/77) or intermittent therapy in response to attacks (17/77). Although intermittent therapy was less restrictive than continuous therapy, medical supervision under the former was less rigorous. The median maintenance dose was 100 mg/week, and did not reflect the initial dose (r = 0.18). The intermittent-treatment group's median dose was significantly lower and its median duration of thalidomide intake significantly longer than for patients on continuous therapy (19 vs. 150 mg/wk; p < 0.0001, and 32 vs. 19 mo; p = 0.002, respectively). Adverse events were reported by 84% (77/92) of patients. They were mostly mild (78% of patients), but sometimes severe (21%). Nevertheless, after 40 months of follow-up, 60% of patients were still receiving continuous or intermittent maintenance therapy with favorable efficacy/tolerance ratios. Despite its retrospective nature, this detailed study provides novel information on the different ways thalidomide is used as SRAS maintenance therapy in a large and unselected cohort of patients. Low-dose maintenance regimens appear to be widely used, effective, and relatively well tolerated. These observations suggest the value of undertaking a randomized trial to assess various maintenance regimens.

Abstract
Recurrent aphthous stomatitis (RAS; aphthae; canker sores) is common worldwide. Characterised by multiple, recurrent, small, round, or ovoid ulcers with circumscribed margins, erythematous haloes, and yellow or grey floors, it usually presents first in childhood or adolescence. Its aetiology and pathogenesis is not entirely clear, but there is genetic predisposition, with strong associations with interleukin genotypes, and sometimes a family history. Diagnosis is on clinical grounds alone, and must be differentiated from other causes of recurrent ulceration, particularly Behçet disease - a systemic disorder in which aphthous-like ulcers are associated with genital ulceration, and eye disease (particularly posterior uveitis). Management remains unsatisfactory, as topical corticosteroids and most other treatments only reduce the severity of the ulceration, but do not stop recurrence.

Abstract
Recurrent aphthous stomatitis (RAS; aphthae; canker sores) is a common condition which is characterized by multiple recurrent small, round or ovoid ulcers with circumscribed margins, erythematous haloes, and yellow or grey floors typically presenting first in childhood or adolescence. RAS occurs worldwide although it appears most common in the developed world. The aetiology of RAS is not entirely clear. Despite many studies trying to identify a causal microorganism, RAS does not appear to be infectious. A genetic predisposition is present, as shown by strong associations with genotypes of IL-1beta; IL-6 in RAS patients, and a positive family history in about one-third of patients with RAS. Haematinic deficiency is found in up to 20% of patients. Cessation of smoking may precipitate or exacerbate RAS in some cases. Ulcers similar to RAS may be seen in human immunodeficiency virus disease and some other immune defects, and drugs, especially non-steroidal anti-inflammatory drugs and nicorandil may produce lesions clinically similar to RAS. Topical corticosteroids can often control RAS. However, the treatment of RAS remains unsatisfactory, as most therapies only reduce the severity of the ulceration and do not stop recurrence.

Abstract
Thalidomide was first introduced in the 1950s as a sedative but was quickly removed from the market after it was linked to cases of severe birth defects. However, it has since made a remarkable comeback for the U.S. Food and Drug Administration-approved use in the treatment of erythema nodosum leprosum. Further, it has shown its effectiveness in unresponsive dermatological conditions such as actinic prurigo, adult Langerhans cell histiocytosis, aphthous stomatitis, Behçet's syndrome, graft-versus-host disease, cutaneous sarcoidosis, erythema multiforme, Jessner-Kanof lymphocytic infiltration of the skin, Kaposi sarcoma, lichen planus, lupus erythematosus, melanoma, prurigo nodularis, pyoderma gangrenosum and uraemic pruritus. This article reviews the history, pharmacology, mechanism of action, clinical uses and adverse effects of thalidomide.

Abstract
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.

Abstract
OBJECTIVE To review published data on thalidomide, with emphasis on current knowledge about mechanism of action, new and/or potential dermatologic and nondermatologic therapeutic applications, well-known and emerging adverse effects, and current indications for its safe use. DATA SOURCES Review articles, in vitro research studies, references from retrieved articles, case reports, and clinical trials were identified from a computerized literature search using MEDLINE and OVID (1966-January 2003) and on the Cochrane Clinical Trials Register (January 2003). Information available from meetings' abstract books, Internet, or pharmaceutical companies was also considered. STUDY SELECTION AND DATA EXTRACTION All articles identified as relevant, including those from non-English literature, were considered in an attempt to provide to the reader both the theoretical basis and practical guidelines for thalidomide pharmacotherapy. DATA SYNTHESIS Thalidomide has hypnosedative, antiangiogenic, antiinflammatory, and immunomodulatory properties. Moreover, it has been shown to selectively inhibit the production of tumor necrosis factor-alpha and reduce the expression of various integrin receptors on the membrane of leukocytes and other cell types in a dose-dependent fashion. Controlled trials demonstrated the efficacy of thalidomide in a number of diseases, including erythema nodosum leprosum, lupus erythematosus, aphthosis, graft-versus-host disease, prurigo nodularis, and actinic prurigo. Single case reports or studies in small series have also suggested a possible role for thalidomide in numerous other dermatologic and nondermatologic disorders. Possibly severe and sometimes irreversible risks related to the clinical use of thalidomide include teratogenicity and neurotoxicity. CONCLUSIONS Although teratogenicity and neurotoxicity are significant adverse effects requiring cautious use, thalidomide is an effective therapeutic modality in a variety of difficult-to-treat disorders and, providing careful selection of patients, should offer an acceptable risk-to-benefit ratio.

Abstract
Thalidomide, administered as a sedative and antiemetic decades ago, was considered responsible for numerous devastating cases of birth defects and consequently was banned from markets worldwide. However, the drug remarkably has resurfaced with promise of immunomodulatory benefit in a wide array of immunologic disorders for which available treatments were limited. It is approved by the Food and Drug Administration for erythema nodosum leprosum (ENL). Although the relative paucity of leprosy and ENL worldwide may perceivably limit interest in and knowledge about thalidomide, increasing numbers of new and potential uses expand its applicability widely beyond ENL. Thalidomide, an inhibitor of tumor necrosis factor a, is the best known agent for short-term treatment of ENL skin manifestations, as well as postremission maintenance therapy to prevent recurrence. For this indication, it is effective as monotherapy and as part of combination therapy with corticosteroids. Studies of thalidomide in chronic graft-versus-host disease showed benefit in children and adults as treatment, but not as prophylaxis. The agent has been administered successfully for treatment of cachexia related to cancer, tuberculosis, and human immunodeficiency virus infection, although evidence of efficacy is inconclusive. Thalidomide monotherapy effectively induced objective response in trials in patients with both newly diagnosed and advanced or refractory multiple myeloma. Combination therapy with thalidomide and corticosteroids was also effective in these patients, as well as in treatment of aphthous and genital ulcers. Limited evidence supports the drug's benefit in treatment of Kaposi's sarcoma. Other thalidomide applications include Crohn's disease, rheumatoid arthritis, and multiple sclerosis. Somnolence, constipation, and rash were the most frequently cited adverse effects in studies, but thalidomide-induced neuropathy and idiopathic thromboembolism were critical causes for drug discontinuation. Thalidomide is still contraindicated in pregnant women, women of childbearing age, and sexually active men not using contraception. Clinicians should be conversant with thalidomide in ENL (its primary application) in the natural course of leprosy, as well as in the agent's other applications.

Abstract
Oral ulcers have may possible causes, including immunosuppression and drug therapy. Severe cases of oral ulceration merit special consideration because the ulcers may become large enough to alter the quality of life of the patient. The present case involves a male patient who in 1994 received an orthotopic liver transplantation because of alcoholic cirrhosis. The initial immunosuppressive regimen was induced with tacrolimus (4 mg/d) and prednisone (20 mg/d). Ten months after orthotopic liver transplantation, the patient complained of multiple recurrent oral ulcers, dysphagia, and severe oral pain, which did not respond to any of the treatments over a 3-year period. Approximately 3(1/4) years after these unresponsive ulcers appeared, the reduction of the oral dosage of tacrolimus resulted in the total remission of the ulcers. A retrospective analysis demonstrated that appearance of the ulcers coincided with a dose of 9 mg/d of tacrolimus (whole blood levels of 12 ng/mL); the ulcers did not disappear until the dose was reduced to 4 mg/d (whole blood level of 6.6 ng/mL).

Abstract
OBJECTIVES To report the experience of the investigators and review the major treatment trials conducted for Behçet's disease (BD). METHODS A MEDLINE literature review from 1970 to date was performed on the drugs prescribed for the treatment of BD. Open and controlled clinical studies and indications for the treatment of affected organs are analyzed. RESULTS Glucocorticoids are indicated for the treatment of BD, although no controlled studies have been reported. The combination of corticosteroids and immunosuppressant drugs is used when vital organs are involved. Nonsteroidal anti-inflammatory drugs are of little value in arthritis. In controlled trials, colchicine was efficacious for erythema nodosum and arthritis, particularly in women. Cyclosporine A has a rapid action and when combined with azathioprine is effective in patients with severe uveitis and extraocular manifestations. Chlorambucil is indicated for uveitis and meningoencephalitis. In controlled studies, azathioprine prevented unilateral uveitis from becoming bilateral and improved extraocular symptoms. Pulse cyclophosphamide combined with corticosteroids improves severe systemic vasculitis. Interferon alpha benefits ocular and extraocular manifestations, but controlled studies are lacking. Methotrexate is indicated for uveitis and arthritis, and sulfasalazine improves gastrointestinal vasculitis. In controlled trials, thalidomide was effective for mucocutaneous manifestations, but on its discontinuation the disease exacerbated. Orogenital manifestations are treated with local application of corticosteroids or other medications. CONCLUSIONS Combination therapy is not always efficacious in controlling inflammation. The goal of management is to treat early to avoid recurrences and irreversible damage to the vital organs. With proper management of BD, loss of useful vision was reduced from 75% to 20% of the affected eyes. However, less favorable results are seen for central nervous system and large artery and vein involvement.
