Ulcerative cutaneous sarcoidosis responding to adalimumab

Multisystemic Sarcoidosis Presenting With Leg Ulcers, Pancytopenia, and Polyserositis Was Successfully Treated With Glucocorticoids: A Case Report and Literature Review

INTRODUCTION

Sarcoidosis is a chronic granulomatous disease of unknown etiology. A variety of studies have pointed out that almost every part of the body can be affected, but it most often affected the lungs and intrathoracic lymph nodes. However, cases of sarcoidosis involving multiple organs in one patient are rarely reported. We describe a unique case of sarcoidosis, which was characterized by multiorgan involvement, including leg ulcers, splenomegaly, pancytopenia, and polyserositis. Glucocorticoids were effective during the treatment of the above lesions. This case highlights the diversity of clinical manifestations of sarcoidosis and emphasizes the importance of its differential diagnosis and the periodical follow-up. These are crucial to physicians in the diagnosis and treatment of sarcoidosis.

MAIN SYMPTOMS AND IMPORTANT CLINICAL FINDINGS

A 30-year-old male complained about intermittent fever 3 years ago. A computed tomographic scan of the chest showed lymphadenopathy in the mediastinum and hilar regions. Routine blood tests showed leukopenia and mild anemia. The pathologic result of mediastinal lymph node biopsy was granulomatous lesions; thus, the patient was diagnosed with type II sarcoidosis without glucocorticoid therapy. In the following 2 years, the patient suffered from intermittent fever accompanied by dyspnea, fatigue, occasional cough, less sputum, and apparent weight loss. Abnormal physical examinations included leg ulcers and splenomegaly. Laboratory and physical tests revealed pancytopenia, polyserositis, and enlargement of lymph nodes. The pathological findings of leg ulceration, pleura, and left supraclavicular lymph node all suggested granulomas.

DIAGNOSIS INTERVENTIONS AND OUTCOMES

It strongly suggested sarcoidosis since tuberculosis, lymphoma, and connective tissue disease were all excluded. Due to severe conditions and multiorgan involvement, we tried to provide methylprednisolone for this patient. After 9 months of oral glucocorticoids therapy, his subjective symptoms as well as hematological and radiological findings were all improved. His leg skin ulceration and scab were also completely disappeared.

CONCLUSION

Sarcoidosis has diverse clinical presentations, and many patients present with atypical symptoms. It needs to be timely identified by the clinician and carefully differentiated from other diseases with similar findings so as to make an accurate diagnosis. In this case, the patient had a poor clinical response to glucocorticoids in the early stage of treatment due to the severe condition and multi-organ involvement. It is worth noting that the patient had improved significantly after 9 months of treatment of corticosteroids, which suggested that follow-up is critical.

Ulcerative cutaneous sarcoidosis successfully treated with infliximab

Sarcoidosis is a systemic inflammatory disorder with cutaneous involvement present in 25% of cases. We present a patient with ulcerative sarcoidosis to highlight this unusual presentation of a relatively rare cutaneous condition that was treated successfully using infliximab. The drug is effective in cutaneous sarcoidosis, but relapses can occur after discontinuation. In this article, we reviewed the clinical features and therapeutic modalities for ulcerative cutaneous sarcoidosis.

Biologic Therapy in the Treatment of Cutaneous Sarcoidosis: A Literature Review

Sarcoidosis is an inflammatory disease defined by the presence of non-caseating granulomas. It can affect a number of organ systems, most commonly the lungs, lymph nodes, and skin. Cutaneous manifestations of sarcoidosis can impose a significant detriment to patients' quality of life. The accepted first-line therapy for cutaneous sarcoidosis consists of intralesional and oral corticosteroids, but these can fail in the face of resistant disease and corticosteroid-induced adverse effects. Second-line agents include tetracyclines, hydroxychloroquine, and methotrexate. Biologics are an emerging treatment option for the management of cutaneous sarcoidosis, but their role in management is not well-defined. In this article, we reviewed the currently available English-language publications on the use of biologics in managing cutaneous sarcoidosis. Although somewhat limited, the data in published studies support the use of both infliximab and adalimumab as third-line treatments for chronic or resistant cutaneous sarcoidosis. There were also scattered reports of etanercept, rituximab, golimumab, and ustekinumab being utilized as third-line agents with varying degrees of success. Larger and more extensive investigations are required to further assess the adverse effect profile and optimal dosing for managing cutaneous sarcoidosis.

A practical approach to cutaneous sarcoidosis

Sarcoidosis is a chronic inflammatory disorder that has the potential to affect multiple organs, including the skin. Its cutaneous manifestations are varied and can provide clues to underlying systemic manifestations. Unfortunately, they also can be disfiguring. Therapy is usually directed at the organ system most severely affected, which often may help cutaneous disease. However, cutaneous disease may be recalcitrant to treatment directed at extracutaneous disease, or it may be severe enough to require targeted therapy. This article focuses on the dermatologist's role in recognizing and diagnosing cutaneous sarcoidosis, evaluating patients for systemic disease involvement, and treating the skin manifestations of sarcoidosis.

Exacerbation of recalcitrant cutaneous sarcoidosis with adalimumab--a paradoxical effect? A case report

The paradoxical adverse effects of tumor necrosis factor-alpha (TNF-alpha) antagonists have been described frequently as a result of the widespread use of these drugs. Among the TNF-alpha blocking agents, few reports exist relating the use of adalimumab in cutaneous sarcoidosis, although all of them show good results. More recently, sarcoidosis onsets have been reported with various TNF-alpha inhibitors. The current case is, to our knowledge, the first to describe the exacerbation of cutaneous lesions of sarcoidosis treated with adalimumab.

Sarcoidosis Can Present with Necrotizing Granulomas Histologically: Two Cases of Ulcerated Sarcoidosis and Review of the Literature

Background:

Sarcoidosis is a systemic inflammatory disorder with cutaneous involvement present in 25% of cases. The presence of naked granulomas histologically is the hallmark of sarcoidosis. The presence of necrotizing granulomas is highly suggestive of other granulomatous conditions and leads the clinician to pursue other diagnoses, such as infectious causes.

Objectives:

We describe two cases of sarcoidosis in which necrotizing granulomas were present on biopsy. Both patients had ulcerated cutaneous lesions of sarcoidosis. In one case, the presence of these atypical histologic features led to a delay in diagnosis of almost 10 years. We review the various histopathologic findings associated with cutaneous sarcoidosis and discuss a potential connection between ulcerated sarcoidosis and atypical histologic findings.

Conclusion:

When atypical histopathologic features are present, the differential diagnosis of sarcoidosis should not be excluded.

Monitoring of nonsteroidal immunosuppressive drugs in patients with lung disease and lung transplant recipients: American College of Chest Physicians evidence-based clinical practice guidelines

OBJECTIVES

Immunosuppressive pharmacologic agents prescribed to patients with diffuse interstitial and inflammatory lung disease and lung transplant recipients are associated with potential risks for adverse reactions. Strategies for minimizing such risks include administering these drugs according to established, safe protocols; monitoring to detect manifestations of toxicity; and patient education. Hence, an evidence-based guideline for physicians can improve safety and optimize the likelihood of a successful outcome. To maximize the likelihood that these agents will be used safely, the American College of Chest Physicians established a committee to examine the clinical evidence for the administration and monitoring of immunosuppressive drugs (with the exception of corticosteroids) to identify associated toxicities associated with each drug and appropriate protocols for monitoring these agents.

METHODS

Committee members developed and refined a series of questions about toxicities of immunosuppressives and current approaches to administration and monitoring. A systematic review was carried out by the American College of Chest Physicians. Committee members were supplied with this information and created this evidence-based guideline.

CONCLUSIONS

It is hoped that these guidelines will improve patient safety when immunosuppressive drugs are given to lung transplant recipients and to patients with diffuse interstitial lung disease.

A case series of refractory cutaneous sarcoidosis successfully treated with infliximab

INTRODUCTION

Sarcoidosis is a systemic granulomatous disease of unknown cause. The management of sarcoidosis remains problematic. Systemic and topical corticosteroids are the mainstay of therapy but may cause unacceptable side effects. Biologic therapies, such as infliximab, have recently been proposed as another treatment option for cutaneous sarcoidosis.

CASE REPORT

The authors describe three patients who were diagnosed with cutaneous sarcoidosis with systemic involvement. All of the patients were refractory to conventional therapies but responded to infliximab therapy.

CONCLUSION

Infliximab is an alternative medication for refractory sarcoidosis that has a relatively benign side-effect profile. However, definite indications, dosage, interval, and duration of treatment for cutaneous sarcoidosis are not firmly established.

Sarcoidosis: a comprehensive review and update for the dermatologist: part I. Cutaneous disease

Sarcoidosis is a common systemic, noncaseating granulomatous disease of unknown etiology. The development of sarcoidosis has been associated with a number of environmental factors and genes. Cutaneous sarcoidosis, the "great imitator," can baffle clinicians because of its diverse manifestations and its ability to resemble both common and rare cutaneous diseases. Depending on the type, location, and distribution of the lesions, treatment can prevent functional impairment, symptomatic distress, scarring, and disfigurement. Numerous therapeutic options are available for the treatment of cutaneous sarcoidosis, but there are few well designed trials to guide practitioners on evidence-based, best practice management. In part I, we review the current knowledge and advances in the epidemiology, etiology, pathogenesis, and genetics of sarcoidosis, discuss the heterogeneous manifestations of cutaneous sarcoidosis, and provide a guide for treatment of cutaneous sarcoidosis.

[Misdiagnosed childhood sarcoidosis as non-Langerhans' cell histiocytosis treated with tumor necrosis factors-α antagonists]

Sarcoidosis is a chronic multisystemic granulomatous disease of unknown origin. Generalised eruptive histiocytosis is a rare, benign, self-healing, non-Langerhans' cell histiocytosis (non-LCH). We report the case of an 8-year-old girl with sarcoidosis who was misdiagnosed as non-LCH. She was treated with oral corticosteroids, methotrexate and adalimumab, but there was insufficient control of ocular disease. The introduction of infliximab achieved a control of the uveitis and enabled the corticosteroid dose to be tapered. In some cases of sarcoidosis the lack of well-organised granuloma formation at the beginning of the disease, and the presence of prominent giant cells may suggest alternative diagnoses, such as non-LCH. Although the experience of tumour necrosis factor-α antagonists use in children with sarcoidosis is limited, these drugs may be helpful for those patients experiencing a severe and refractory disease.

Adalimumab successful in sarcoidosis patients with refractory chronic non-infectious uveitis

INTRODUCTION

Adalimumab, a humanized monoclonal antibody targeted against TNF-α, has proved to be successful in the treatment of uveitis. Another anti-TNF-α agent, i.e., infliximab, has been reported of benefit in the treatment of refractory sarcoidosis. The aim of this prospective case series was to evaluate the effect of adalimumab on intraocular inflammatory signs and other relevant clinical manifestations (lung function, serological inflammatory parameters, and fatigue) of sarcoidosis.

METHODS

Sarcoidosis patients with refractory posterior uveitis (n = 26, 17 females, 41 eyes in total) were systematically followed for 12 months after initiation of adalimumab 40 mg sc once a week. Inclusion criteria were non-responsiveness to prednisone and methotrexate (MTX) or intolerance to these drugs. Adjunctive therapy with prednisone and MTX was tapered during treatment with adalimumab. Localization and improvement, stabilization or deterioration of intraocular inflammatory signs was scored. Pulmonary function- and laboratory testing were performed and Fatigue Assessment Scale was completed. Results at baseline, 6 months, and 12 months were compared.

RESULTS

Choroidal involvement resolved in 10/15 patients, five had partial improvement; vasculitis resolved in 1/1 patient; papillitis resolved in 7/8 patients, one had partial response; macular edema resolved in 5/8 patients, three had partial response; vitreous cleared completely in 5/5 patients. Overall outcome regarding intraocular inflammatory signs showed improvement in 22 patients (85%) and stabilization in four patients (15%). At 12 months, no recurrences were reported in those successfully treated. Laboratory parameters of inflammatory activity (C-reactive protein; serum angiotensin-converting enzyme and soluble interleukin-2 Receptor) improved (p < 0.01). Moreover, fatigue improved in 14/21 (67%) of the patients suffering from fatigue and the diffusion capacity for carbon monoxide (DLCO) improved in 7/8 (88%) of patients with a decreased DLCO (p < 0.01). The dosage of both prednisone and MTX could be tapered down significantly (p < 0.01 and p < 0.05, respectively).

CONCLUSIONS

Adalimumab appeared successful in sarcoidosis patients with refractory chronic non-infectious uveitis showing improvement in intraocular inflammatory signs as well as in other relevant clinical indicators of disease activity. Future randomized studies are needed to determine the optimal dosage, dose interval and duration of therapy in refractory multisystemic sarcoidosis.

Tumor necrosis factor-alpha inhibitor treatment for sarcoidosis

Sarcoidosis is a chronic multisystem disease of unknown etiology, characterized by noncaseating granulomatous infiltration of virtually any organ system. Treatment is often undertaken in an attempt to resolve symptoms or prevent progression to organ failure. Previous studies have suggested a prominent role for tumor necrosis factor-alpha (TNF-α) in the inflammatory process seen in sarcoidosis. TNF-α and interleukin-1 are released by alveolar macrophages in patients with active lung disease. Corticosteroids have proved to be efficacious in the treatment of sarcoidosis, possibly by suppressing the production of TNF-α and other cytokines. Three agents are currently available as specific TNF antagonists: etanercept, infliximab, and adalimumab. Although data from noncomparative trials suggest that all three have comparable therapeutic effects in rheumatoid arthritis, their effects in a granulomatous disease such as sarcoidosis are less consistent. In this review, current data on the effectiveness are summarized.

Tumor necrosis factor biologics beyond psoriasis in dermatology

INTRODUCTION

TNF-α is a cytokine essential for immune response and its receptors has been shown to be dysregulated in a variety of diseases including psoriasis vulgaris. There are a number of TNF-α inhibitors approved for psoriasis, however there is a growing body of literature supporting their use in a wide variety of dermatological conditions.

AREAS COVERED

The use of biologic TNF-α antagonists in conditions for which they have not yet been approved by the FDA ('off-label' uses) and the literature that supports the most appropriate agents and conditions for use. A PubMed/MEDLINE search was performed with the keywords 'TNFα antagonist', 'biologic therapy', 'off-label' and 'unapproved'. The list of references and citing articles of the articles retrieved were also used as sources. This complete list was evaluated for inclusion, based on relevance to the proposed goal of this review.

EXPERT OPINION

There are a large number of conditions for which biologic antagonists of TNFα are effective, beyond those already approved by the FDA. The various agents vary in their efficacy in treatment, with infliximab consistently the most effective, particularly in granulomatous diseases. Although effectiveness varies among these conditions, biologic antagonists of TNF-α are promising for the treatment of these diseases.

Cytokine modulators in the treatment of sarcoidosis

Sarcoidosis is a granulomatous lung disease in which several cytokines play a pivotal pathogenetic role. Steroid-resistant disease can be treated with immunosuppressive drugs, antimalarial therapies and recently with anti-TNFα agents. The use of biological agents for the treatment of sarcoidosis springs from research into the pathogenesis of the disease and also from the experience of rheumatologists with other chronic inflammatory diseases. Rituximab, golimumab and ustekinumab are cytokine modulators, useful in the treatment of immunoinflammatory disorders, for which randomized trials to evaluate safety and efficacy in sarcoidosis are not yet available. Novel anticytokine drugs administered alone or in association may offer a new approach to treatment of the disease. This review focuses on recent advances in anti-TNFα agents and cytokine modulators for the treatment of sarcoidosis and their therapeutic prospects.

Innovative uses of tumor necrosis factor alpha inhibitors

Tumor necrosis factor alpha (TNF-alpha) is an inflammatory cytokine that is released by a variety of cell types, including immune effector cells and tissue-specific cells. TNF-alpha has been shown to promote inflammation via the activation and induction of cytokines interleukin 1 (IL-1), IL-6, and IL-8 and by the upregulation of adhesion molecules on endothelial cells leading to increased leukocyte extravasation. Theoretically, the blockade of TNF should have widespread potential in the treatment of numerous inflammatory diseases. Currently, 3 TNF-alpha inhibitors available in the United States are approved for psoriasis and psoriatic arthritis: infliximab, etanercept, and adalimumab. Numerous case reports and case series have been published in recent years reporting the off-label uses of these drugs in various inflammatory skin diseases. This review summarizes the most recent reports on 20 such conditions.

Development of sarcoidosis during adalimumab therapy for chronic plaque psoriasis

A 38-year-old woman developed clinical, biochemical, radiological and histopathological evidence of cutaneous and pulmonary sarcoidosis 5 months after commencing adalimumab for chronic plaque psoriasis. Signs and symptoms resolved within 3 months of cessation of adalimumab.

[TNFα blocking agents and sarcoidosis: an update]

Increased production of TNFα by alveolar macrophages and involvement of TNFα in granuloma formation suggest that this cytokine is involved in the pathophysiology of sarcoidosis. The three available TNFα blocking agents have been tested in sarcoidosis refractory to corticosteroids or immunosuppressive drugs. Data are available from isolated case reports or limited series of patients treated in open label trials with favourable issue with anti-TNFα monoclonal antibodies. Two randomized placebo controlled studies evaluated the efficacy of infliximab in pulmonary and extra-pulmonary sarcoidosis, showing that infliximab improves significantly extra-pulmonary disease. There is no significant difference between infliximab and placebo in the treatment of pulmonary manifestations. Etanercept showed no efficacy for treating ocular sarcoidosis in a controlled trial and for pulmonary disease in an open label trial. Paradoxical cases of proven sarcoidosis have been reported in patients receiving anti-TNFα agents for chronic inflammatory rheumatic diseases. A literature review identified 28 cases, including 16 with etanercept, eight with infliximab and four with adalimumab. Although these cases were mainly reported with etanercept, paradoxical sarcoidosis has been reported with the three available anti-TNFα agents, suggesting a class effect. Changes in the cytokine balance may be involved in these cases of induced sarcoidosis, which must be known by the clinician.

[Systematic review on the use of adalimumab in autoinmune. Efficacy and safety in 54 patients]

OBJECTIVE

To analyze published evidence about adalimumab use in autoimmune diseases.

METHODS

Systematic review of MEDLINE database of citations included from January 1990 to December 2008 employing the terms "adalimumab" and the different systemic autoimmune diseases.

RESULTS

Our search identified 241 potentially relevant citations. 154 were retrieved for detailed evaluation. Finally, 18 were selected as relevant, including 54 patients. The reported diseases were as follow: Behçet disease in 16 patients, idiopathic uveitis in 13, sarcoidosis in 5, uveitis associated with rheumatologic diseases in 5 (psoriasis in 2, ankylosing spondylitis in 1, juvenile idiopathic arthritis in 1, Crohn disease in 1), Vogt-Koyanagi-Harada disease in 4, Birdshot uveitis in 4, vasculitis in 3 (1 temporal arteritis, 1 Takayasu's disease, 1 skin vasculitis associated with rheumatoid arthritis), adult onset Still disease in 2, relapsing polychondritis in 1 and systemic sclerosis in 1. The clinical spectrum included uveitis (39 cases), skin and/or mucosae (9), vasculitis (3), arthritis (6), lung (3). These patients were refractory to standard therapy, including corticosteroids (42 cases, 78%), immunosuppressants (42, 78%) and biologics (29, 54%). Fifty (93%) patients responded to adalimumab. The clinical response was similar in those patients who had been treated with other biologic and in those who had not received biologic therapy before adalimumab. The patients were followed for 11.9 months. Twelve (22%) patients relapsed. Five (9%) patients suffer some side effect (3 local skin reaction, 1 angioedema, 1 lung fibrosis). One patient (2%) died due to progression of her disease.

CONCLUSIONS

Available data about the use of adalimumab in autoinmune diseases come from case reports and uncontrolled studies, that include patients with severe disease and refractory to standard therapy. In this setting, it seems to be an effective and safe treatment option, especially in patients with uveitis and Behçet's disease. This initial data must be confirmed by controlled assays before extending adalimumab use.

Treatment of sarcoid granulomatous interstitial nephritis with adalimumab

Sarcoidosis is a systemic disease with multiorgan involvement which can cause renal failure through several different mechanisms. Granulomatous interstitial nephritis is an important albeit less frequent cause of clinically significant renal disease. Herein, we present the case of a 46 year old woman with a history of sarcoidosis whom we evaluated for rapidly worsening kidney function and proteinuria. Renal biopsy revealed granulomatous interstitial nephritis. After therapy with adalimumab, her renal function improved with a significant reduction in proteinuria. Repeat kidney biopsy showed resolution of renal granulomata. To our knowledge, this is the first report of successful treatment of granulomatous interstitial nephritis with adalimumab.

Adalimumab in dermatology

Adalimumab is a biological agent, one of the tumour necrosis factor-alpha inhibitors. Pivotal studies evaluating its efficacy in plaque psoriasis (CHAMPION, REVEAL) and psoriatic arthritis (PsA) (ADEPT) were carried out in recent years. Adalimumab proved highly effective in psoriasis patients and in PsA patients previously unresponsive to nonsteroidal anti-inflammatory drugs. Results of smaller studies suggest therapy with the drug may be successful in psoriasis resistant to other biologics and PsA unresponsive to disease-modifying antirheumatic drugs. Adalimumab has also been shown to improve patients' quality of life significantly. Although they should be further extended as far as dermatological conditions are concerned, available data indicate adalimumab is safe and well tolerated. Numerous case reports featuring its off-label use suggest the drug could be helpful in treating hidradenitis suppurativa, pyoderma gangrenosum, Sweet's syndrome, cutaneous sarcoidosis, pemphigus, systemic vasculitides, multicentric reticulohistiocytosis and stomatitis.

Sarcoidosis, role of tumor necrosis factor inhibitors and other biologic agents, past, present, and future concepts

Tumor necrosis factor is a potent cytokine involved in the inflammatory process of many diseases. Agents that block tumor necrosis factor have been used in the treatment of various immune-mediated diseases, including rheumatoid arthritis, Crohn disease, psoriatic arthritis, and ankylosing spondylitis. Sarcoidosis is an immune-mediated inflammatory disorder of unknown etiology characterized by the formation of noncaseating granulomas. Tumor necrosis factor plays a major role in the inflammatory process seen in sarcoidosis. Sarcoidosis therapies with activity against tumor necrosis factor and specific anti-tumor necrosis factor therapies have been used with variable success. The long-term safety and efficacy of such therapies are yet to be determined in well-designed clinical trials with long-term follow-up.

Steroid-resistant sarcoidosis: is antagonism of TNF-alpha the answer?

Steroid-resistant sarcoidosis has conventionally been treated with various drugs, including methotrexate, azathioprine, cyclophosphamide, cyclosporine, antimalarial drugs and thalidomide, with variable success. There is a compelling need for more efficient and safer alternatives to these agents. Several lines of evidence suggest a critical role of TNF-alpha (tumour necrosis factor-alpha) in the initiation and organization of sarcoid granulomas. Inhibition of TNF-alpha with monoclonal antibodies has therefore received attention as a potential treatment option in therapy-resistant sarcoidosis. A number of case reports and small case series describe successful treatment of refractory disease with infliximab. Preliminary evidence from an RCT (randomized controlled trial) with infliximab in pulmonary sarcoidosis suggests a modest improvement in functional and radiological parameters. In contrast, the results with etanercept have been disappointing, perhaps related to differences in the mechanism of TNF-alpha blockade. The experience with adalimumab in sarcoidosis is too limited to draw conclusions. An open-label study and an RCT evaluating the efficacy of adalimumab in sarcoidosis with pulmonary and cutaneous involvement respectively, have been initiated. Although TNF-alpha antagonists appear relatively safe, especially when compared with conventional agents, caution is warranted in view of the increased incidence of tuberculosis, which may be a particular diagnostic challenge in patients with sarcoidosis. Pending publication of the RCTs, the use of TNF-alpha blockade in sarcoidosis should remain in the realm of experimental treatment.

Off-label uses of biologics in dermatology: Rituximab, omalizumab, infliximab, etanercept, adalimumab, efalizumab, and alefacept (Part 2 of 2)

Recently, dermatologists have witnessed a revolution in our therapeutic armamentarium with the development of several novel biologic immunomodulators. Although psoriasis remains the only condition in dermatology for which the use of biologic immunomodulators has been approved by the Food and Drug Administration, these drugs have the potential to significantly impact the treatment of several inflammatory conditions in dermatology. This article includes a review of the mechanism of action, dosing, and side-effect profile, as well as a review of the current literature on off-label uses of the CD20-positive B-cell antagonist rituximab, the IgE antagonist omalizumab, the tumor necrosis factor-alpha antagonists infliximab, etanercept, and adalimumab, and the T-cell response modifiers efalizumab and alefacept.
