Abstract
Systemic lupus erythematosus (SLE), a common autoimmune disease with a global incidence and newly diagnosed population estimated at 5.14 (range, 1.4-15.13) per 100,000 person-years and 0.40 million people annually, respectively, affects multiple tissues and organs; for example, skin, blood system, heart and kidneys. Accumulating data has also demonstrated that psoriasis (PS) can be a systemic inflammatory disease, which can affect organs other than the skin and occur alongside other autoimmune diseases, such as inflammatory bowel disease, multiple sclerosis, rheumatoid arthritis and SLE. The current explanations for the possible comorbidity of PS and SLE include: i) The two diseases share susceptible gene loci; ii) they share a common IL-23/T helper 17 (Th17) axis inflammatory pathway; and iii) the immunopathogenesis of the two conditions is a consequence of the interactions between IL-17 cytokines with effector Th17 cells, T regulatory cells, as well as B cells. In addition, the therapeutic efficacy of IL-17 or TNF-α inhibitors has been demonstrated in PS, and has also become evident in SLE. However, the mechanisms have not been investigated. To the best of our knowledge, there remains a lack of substantial studies on the correlation between PS and SLE. In the present review, the literature, with regards to the epidemiology, genetic predisposition, inflammatory mechanisms and treatment of the patients with both PS and SLE, has been reviewed. Further investigations into the molecular pathogenic mechanism may provide drug targets that could benefit the patients with concomitant PS and SLE.

Context dependent induction of autoimmunity by TNF signaling deficiency. JCI Insight 2022; 7:149094.

Abstract
TNF inhibitors are widely used to treat inflammatory diseases; however, 30%–50% of treated patients develop new autoantibodies, and 0.5%–1% develop secondary autoimmune diseases, including lupus. TNF is required for formation of germinal centers (GCs), the site where high-affinity autoantibodies are often made. We found that TNF deficiency in Sle1 mice induced TH17 T cells and enhanced the production of germline encoded, T-dependent IgG anti-cardiolipin antibodies but did not induce GC formation or precipitate clinical disease. We then asked whether a second hit could restore GC formation or induce pathogenic autoimmunity in TNF-deficient mice. By using a range of immune stimuli, we found that somatically mutated autoantibodies and clinical disease can arise in the setting of TNF deficiency via extrafollicular pathways or via atypical GC-like pathways. This breach of tolerance may be due to defects in regulatory signals that modulate the negative selection of pathogenic autoreactive B cells.

Abstract
AIM The purpose of this study was to investigate the prevalence of antinuclear antibody (ANA) positivity in a cohort of patients with hidradenitis suppurativa (HS), and to assess the frequency of seroconversion during treatment with tumor necrosis factor (TNF)-α inhibitor therapy. METHODS This prospective study was conducted through the Wound Etiology and Healing (WE-HEAL) Study. Immunofluorescence ANA testing was performed at baseline, and repeated when clinically indicated. ANA titers of ≥1 : 160 were considered positive. Data were collected on demographics and disease activity scores including the Hurley stage, the HS Sartorius score (HSS) and the active nodule (AN) count. RESULTS At the time of data lock, 73 patients with a confirmed diagnosis of HS were enrolled, and four (5.4%) had baseline positive ANA. None of the patients had clinical evidence of systemic lupus erythematosus or other autoimmune diseases. There were no significant differences in demographics, baseline HSS (43.25 ± 47.55 compared to 59.48 ± 56.67, P = 0.58) or AN count (3.25 ± 3.20 compared to 3.45 ± 2.36, P = 0.87) in the ANA positive group. Of the 69 patients who were ANA negative at enrollment, 31 (45%) received TNF-α inhibitor therapy. During follow up, one patient developed drug-induced lupus secondary to TNF-α inhibitor use. Additionally, one patient seroconverted to ANA positive without sequelae and one patient developed drug-induced hepatitis secondary to TNF-α inhibitor use. CONCLUSION The prevalence of baseline ANA positivity in this HS population was similar to that seen in the general population (5.4%). The rate of seroconversion and drug-induced complications in this population were low.

Abstract
Rheumatoid Arthritis (RA) is a chronic inflammatory disease of erosive nature that tends to progress to juxta-articular destruction and ankylosis. The pathological events that lead to joint destruction are due, in part, to an enhanced expression of Tumour Necrosis Factor (TNF). It has been shown that TNF-α blocking agents significantly reduce joint inflammation and slow down the progression of radiographic joint damage. Etanercept is a biological drug obtained through recombinant DNA techniques that acts by inhibiting the cellular response mediated by TNF. The aim of this study is to evaluate the efficacy and tolerance of Etanercept in patients affected by active Rheumatoid Arthritis non- responsive to standard traditional therapies. All patients presented an improvement in the illness. Our study concords with the most recent data from literature that Etanercept acts rapidly and offers a quick and long-lasting reduction of illness activity, as well as an improvement in functional capability and quality of life in patients affected by active RA.

Abstract
Since the first reported use in 2001 of an anti-tumor necrosis factor-alpha (TNF-α) agent, infliximab, for the treatment of uveitis, several new anti-TNF-α agents have emerged for the treatment of refractory noninfectious uveitides, although their use remains off-label in the US. These agents have demonstrated remarkable clinical antiinflammatory efficacy and a potential immunoregulatory role in selected uveitis patients, but it is currently unclear whether they can modify the natural history of disease. We review the rationale and clinical indications for this therapy, the differences between agents, how to manage dosing and intervals, and how to screen for and identify potential side effects. We also present a summary of the science behind the use of anti-TNF-α agents in ocular inflammation and the evidence for their efficacy.

Abstract
Many studies have explored the pathology of systemic lupus erythematosus (SLE), an autoimmune rheumatic disorder with a striking female predominance. Numerous autoimmune phenomena are present in this disease, which ultimately result in organ damage. However, the specific cellular and humoral mechanisms underlying the immune dysfunction are not yet fully understood. It is postulated that autoimmunity is based on the interaction of genetic predisposition, hormonal and environmental triggers that result in reduced tolerance to self-tissues. These phenomena could occur because of altered antigen presentation, abnormalities in B cell responses, increases in the function of T-helper cells, abnormal cytokine production, exaggerated effector responses, or loss of regulatory T cells or B cells. Abnormalities in all of these components of the immune response have been implicated to varying degrees in the pathogenesis of SLE. This chapter will attempt to provide a "state-of-the-art" review of the evidence about the mechanisms underlying the pathology of SLE.

Abstract
The pathogenesis of systemic lupus erythematosus (SLE) entails a complex interaction between the different arms of the immune system. While autoantibodies production and immune complex deposition are cornered as hallmark features of SLE, there is growing evidence to propose the pathogenic role of cytokines in this disease. Examples of these cytokines include BLys, interleukin-6, interleukin-17, interleukin-18, type I interferons and tumour necrosis factor alpha. These cytokines all assume pivotal functions to orchestrate the differentiation, maturation and activation of various cell types, which would mediate local inflammatory process and tissue injury. The knowledge on these cytokines not only fosters our understanding of the disease, but also provides insights in devising biomarkers and targeted therapies. In this review, we focus on cytokines which have substantial pathogenic significance and also highlight the possible clinical applications of these cytokines.

Abstract
Galectin-9 ameliorates various murine autoimmune disease models by regulating T cells and macrophages, although it is not known what role it may have in B cells. The present experiment shows that galectin-9 ameliorates a variety of clinical symptoms, such as proteinuria, arthritis, and hematocrit in MRL/lpr lupus-prone mice. As previously reported, galectin-9 reduces the frequency of Th1, Th17, and activated CD8(+) T cells. Although anti-dsDNA antibody was increased in MRL/lpr lupus-prone mice, galectin-9 suppressed anti-dsDNA antibody production, at least partly, by decreasing the number of plasma cells. Galectin-9 seemed to decrease the number of plasma cells by inducing plasma cell apoptosis, and not by suppressing BAFF production. Although about 20% of CD19(-/low) CD138(+) plasma cells expressed Tim-3 in MRL/lpr lupus-prone mice, Tim-3 may not be directly involved in the galectin-9-induced apoptosis, because anti-Tim-3 blocking antibody did not block galectin-9-induced apoptosis. This is the first report of plasma cell apoptosis being induced by galectin-9. Collectively, it is likely that galectin-9 attenuates the clinical severity of MRL lupus-prone mice by regulating T cell function and inducing plasma cell apoptosis.

Abstract
OBJECTIVE To analyze the mechanism for the therapeutic effects of tumor necrosis factor α (TNFα) inhibition in a murine model of systemic lupus erythematosus. METHODS We used the (NZB × NZW)F(1) (NZB/NZW) mouse model of interferon-α-induced lupus nephritis and treated mice with TNF receptor type II (TNFRII) Ig after TNFα expression was detected in the kidneys. Autoantibodies were measured by enzyme-linked immunosorbent assay (ELISA), and autoantibody- forming cells were determined using an enzyme-linked immunospot assay. Activation of splenocytes was analyzed by flow cytometry. Kidneys were harvested and analyzed using flow cytometry, immunohistochemistry, ELISA, Western blotting, and real-time polymerase chain reaction. RESULTS TNFRII Ig treatment stabilized nephritis and markedly prolonged survival. Autoantibody production and systemic immune activation were not inhibited, but the renal response to glomerular immune complex deposition was attenuated. This was associated with decreases in renal production of chemokines, renal endothelial cell activation, interstitial F4/80(high) macrophage accumulation, tubular damage, and oxidative stress. In contrast, perivascular lymphoid aggregates containing B cells, T cells, and dendritic cells accumulated unabated. CONCLUSION Our data suggest that TNFα is a critical cytokine that amplifies the response of the nephron to immune complex deposition, but that it has less influence on the response of the systemic vasculature to inflammation.

Abstract
Effective treatment with etanercept results from a congregation of immunological signaling and modulating roles played by tumor necrosis factor-alpha (TNF-alpha), a pervasive member of the TNF super-family of cytokines participating in numerous immunologic and metabolic functions. Macrophages, lymphocytes and other cells produce TNF as part of the deregulated immune response resulting in psoriasis or other chronic inflammatory disorders. Tumor necrosis factor is also produced by macrophages and lymphocytes responding to foreign antigens as a primary response to potential infection. Interference with cytokine signaling by etanercept yields therapeutic response. At the same time, interference with cytokine signaling by etanercept exposes patients to potential adverse events. While the efficacy of etanercept for the treatment of psoriasis is evident, the risks of treatment continue to be defined. Of the potential serious adverse events, response to infection is the best characterized in terms of physiology, incidence, and management. Rare but serious events: activation of latent tuberculosis, multiple sclerosis, lymphoma, and others, have been observed but have questionable or yet to be defined association with therapeutic uses of etanercept. The safe use of etanercept for the treatment of psoriasis requires an appreciation of potential adverse events as well as screening and monitoring strategies designed to manage patient risk

Abstract
Etanercept (ETN) is the first anti-tumor necrosis factor (TNF) agent to be approved for the treatment of rheumatoid arthritis (RA). Over the last 8 years, several clinical trials have shown its efficacy and safety in established and early RA, as well as a monotherapy or in combination with methotrexate. ETN not only reduces the signs and symptoms of RA, but also retards the progression of radiographic damage and improves the quality of life and function of patients. Its safety profile has been predictable since the first clinical trials with no new major safety concerns. Beyond its efficacy in RA, ETN is also indicated for the treatment of psoriatic arthritis. This current report reviews the evidence and the data in RA and psoriatic arthritis (PsA).

Abstract
Systemic lupus erythematosus (SLE) is a complex auto-immune disorder which involves various facets of the immune system. In addition to autoantibody production and immune complex deposition, emerging evidences suggest that cytokines may act as key players in the immunopathogenesis of SLE. These cytokines assume a critical role in the differentiation, maturation and activation of cells and also participate in the local inflammatory processes that mediate tissue insults in SLE. Certain cytokines such as the IL-6, IL-10, IL-17, BLys, type I interferons (IFN) and tumor necrosis factor-α (TNF-α) are closely linked to pathogenesis of SLE. The delineation of the role played by these cytokines not only fosters our understanding of this disease but also provides a sound rationale for various therapeutic approaches. In this context, this review focuses on selected cytokines which exert significant effect in the pathogenesis of SLE and their possible clinical applications.

Abstract
Immunologic research has clarified many aspects of the pathogenesis of inflammatory rheumatic disorders. Biologic drugs acting on different steps of the immune response, including cytokines, B- and T-cell lymphocytes, have been marketed over the past 10 years for the treatment of rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA). Randomized controlled trials (RCTs) of anti-cytokine agents in RA (including the anti-tumor necrosis factor alpha (TNFα) drugs infliximab, etanercept, adalimumab, golimumab, certolizumab, anti-interleukin (IL)-1 anakinra, and anti-IL-6 tocilizumab) demonstrated a significant efficacy compared to traditional therapies, if combined with methotrexate (MTX), as measured by ACR 20, 50 and 70 response criteria. The new therapies have also been demonstrated to be superior to MTX in slowing or halting articular damage. RCTs have shown the efficacy of anti-TNFα in AS patients through significant improvement of symptoms and function. Trials of anti-TNFα in PsA patients showed marked improvement of articular symptoms for psoriasis and radiological disease progression. More recent studies have demonstrated the efficacy of B-cell depletion with rituximab, and T-cell inactivation with abatacept. All these drugs have a satisfactory safety profile. This paper reviews the different aspects of efficacy and tolerability of biologics in the therapy of RA, AS, and PsA.

Abstract
Drug-induced lupus erythematosus (DILE) is defined as an entity characterized by clinical manifestations and immunopathological serum findings similar to those of idiopathic lupus but which is temporally related to continuous drug exposure and resolves after discontinuation of the offending drug. Similar to idiopathic lupus, DILE can be divided into systemic lupus erythematosus (SLE), subacute cutaneous lupus erythematosus (SCLE) and chronic cutaneous lupus erythematosus (CCLE). Based on the literature review and retrospective analysis of our case series, we focused on the dermatological aspects of DILE. The cutaneous features of drug-induced SLE are protean, including particularly purpura, erythema nodosum and photosensitivity as well as the skin lesions characterizing both urticarial and necrotizing vasculitis. The typical laboratory profile of systemic DILE consists of positive antinuclear antibodies (ANA) and antihistone antibodies, the latter being regarded as the serum marker of this subset. The drugs most frequently implicated in the development of systemic DILE are hydralazine, procainamide, isoniazid and minocycline. Drug-induced SCLE usually presents with annular polycyclic or papulosquamous cutaneous manifestations as in the idiopathic form, but blisters or targetoid lesions mimicking erythema multiforme cannot rarely be associated. The clinical presentation is often generalized, with involvement of the lower legs that are usually spared in idiopathic SCLE. ANA and anti-Ro/SSA antibodies are usually present, whereas antihistone antibodies are uncommonly found. Drugs associated with SCLE include particularly calcium channel blockers, angiotensin-converting enzyme inhibitors, thiazide diuretics, terbinafine and the recently reported tumour necrosis factor (TNF)-α antagonists. Drug-induced CCLE is very rarely described in the literature and usually refers to fluorouracile agents or TNF-α antagonists. The picture is characterized by the occurrence of classic discoid lesions, but aspects of lupus tumidus can occasionally develop. ANA are demonstrated in around two-thirds of the cases. Management of DILE is based on the withdrawal of the offending drug. Topical and/or systemic corticosteroids and other immunosuppressive agents should be reserved for resistant cases.

Abstract
BAFF (B lymphocyte activating factor of the tumour necrosis factor family) is a vital homeostatic cytokine for B cells that helps regulate both innate and adaptive immune responses. Increased serum levels of BAFF are found in a number of different autoimmune diseases, and BAFF is found in inflammatory sites in which there is lymphoid neogenesis. BAFF antagonism has been used in several autoimmune disease models, resulting in B cell depletion, decreased activation of T cells and dendritic cells (DC) and a reduction in the overall inflammatory burden. BAFF, through its interaction with BAFF-R, is required for survival of late transitional, marginal zone and mature naive B cells, all of which are depleted by BAFF blockade. Through their interactions with TACI (transmembrane activator and calcium modulator and cyclophilin ligand interactor) and BCMA (B cell maturation protein), BAFF and its homologue APRIL (a proliferation-inducing ligand), support the survival of at least some subsets of plasma cells; blockade of both cytokines results in a decrease in serum levels of immunoglobulin (Ig)G. In contrast, neither BAFF nor APRIL is required for the survival or reactivation of memory B cells or B1 cells. BAFF also helps DC maturation and interleukin (IL)-6 release and is required for proper formation of a follicular dendritic cell (FDC) network within germinal centres, although not for B cell affinity maturation. The clinical efficacy of BAFF blockade in animal models of autoimmunity may be caused both by the decline in the number of inflammatory cells and by the inhibition of DC maturation within target organs. Blockade of BAFF and its homologue APRIL are being explored for human use; several Phase I and II clinical trials of BAFF inhibitors for autoimmunity have been completed and Phase III trials are in progress.

Abstract
OBJECTIVE To report a case of probable anaphylaxis due to anakinra in a patient with rheumatoid arthritis and multiple drug allergies. CASE SUMMARY A 46-year-old Indian female with rheumatoid arthritis demonstrated distinct adverse reactions to all commercially available anti-tumor necrosis factor therapies, sulfasalazine, and hydroxychloroquine. Over a 4-year period her disease remained active during therapy with methotrexate and prednisone. Biologics were added sequentially, with development of intolerable reactions, first to infliximab (urticarial rash, infusion reactions) after 3 doses, and then to etanercept (autoantibodies, worsening Raynaud's phenomenon, digital microinfarcts) after 1 year. Following 2 months of daily injections of anakinra, she experienced an immediate immunoglobulin E-mediated anaphylactic reaction within 20 minutes of an injection, as evidenced by positive testing to both anakinra and histamine with the skin prick method. The patient subsequently started adalimumab therapy, which was discontinued after the fourth dose due to the development of generalized hives. DISCUSSION The Naranjo probability scale demonstrated a probable relationship between anaphylaxis and anakinra in this patient. Although cases of anakinra-related hypersensitivity have been reported in patients in which therapy was interrupted and then reintroduced, to our knowledge, this is the first report of anaphylaxis with continuous therapy. CONCLUSIONS This unusual case of a patient with multiple drug allergies presents a difficult clinical scenario, which was unsuccessfully managed with multiple biologic therapies on a trial-and-error basis. In the future, pharmacogenetics may help to better identify individuals at risk for multiple drug reactions and preclude unnecessary exposure to potentially harmful therapeutic options in similar patients.

Abstract
Drug-induced lupus is a syndrome which share symptoms and laboratory characteristics with idiopathic systemic lupus erythematosus (SLE). The terms drug-induced lupus (DIL) and drug-induced lupus erythematosus (DILE) are preferred, but other ones are also used-drug-related lupus, lupus-like syndrome and lupus erythematosus medicamentosus. The first case of DILE was reported in 1945 and associated with sulfadiazine. In 1953, it was reported that DILE was related to the use of hydralazine. More than 80 drugs have been associated with DILE. The average age of patients with DILE is nearly twice that of patients with idiopathic SLE. Approximately half the patients with drug-induced SLE are women, compared with 90% of patients with idiopathic SLE. Similarly to idiopathic lupus, DILE can be divided into systemic, sub-acute cutaneous and chronic cutaneous lupus. The syndrome is characterised by arthralgia, myalgia, pleurisy, rash and fever in association with antinuclear antibodies in the serum. The clinical and laboratory manifestations of drug-induced SLE are similar to those of idiopathic SLE, but central nervous system and renal involvement are rare in DILE. Recognition of DILE is important because it usually reverts within a few weeks after stopping the drug. This review discusses the general issues in DILE, such as pathogenic mechanisms, clinical forms and diagnostic criteria, and provides more detailed information for some of the most recent implicated drugs: minocycline, statins, anti-TNF-alpha agents.

Abstract
Autoantibodies and lupus-like syndromes can develop following the use of certain medications; however, although many patients develop autoantibodies, only a minority develop clinical features. Although these autoantibodies primarily consist of antinuclear and antihistone antibodies, additional types of antibody, such as antineutrophil cytoplasmic antibodies and anti-double-stranded DNA antibodies, have been reported in association with minocycline and tumor necrosis factor inhibitor therapy. Clinical features of drug-related lupus usually consist of constitutional symptoms, arthralgias, arthritis, myalgias and serositis, although cutaneous manifestations have been reported in association with the use of tumor necrosis factor inhibitors. Typically, clinical features resolve with discontinuation of the medication, although antibodies can persist for months or years. Arthralgias and inflammatory arthritis have also been reported in association with the use of aromatase inhibitors and other biologic agents such as interleukins and interferons.

Abstract
OBJECTIVES All pharmacologic agents have the potential for both benefit and toxicity. Among the more interesting and important adverse consequences of drug therapy are a range of joint and connective tissue complaints that may mimic or reproduce primary rheumatologic diseases. In this article, we review the literature on commonly used drugs reported to induce arthritis and/or connective tissue-based diseases. We assess the strength of the reported associations, discuss diagnostic features and treatment implications, and consider possible mechanisms for drug-induced genesis of rheumatic conditions. METHODS We reviewed the Medline database from 1987 to 2006 to identify drug-induced arthritic and connective-tissue disease syndromes, utilizing 48 search terms. A qualitative review was performed after the articles were abstracted and the relevant information was organized. RESULTS Three hundred fifty-seven articles of possible relevance were identified. Two hundred eleven publications were included in the final analysis (case series and reports, clinical trials, and reviews). Many drugs were identified as mimicking existing rheumatic conditions, including both well-established small molecules (eg, sulfasalazine) and recently introduced biologic agents (eg, antitumor necrosis factor agents). The most commonly reported drug-induced rheumatic conditions were lupus-like syndromes. Arthritis and vasculitis were also often reported. CONCLUSIONS Drug-induced rheumatic syndromes are manifold and offer the clinician an opportunity to define an illness that may remit with discontinuation of the offending agent. Early diagnosis and withdrawal of the drug may prevent unnecessary morbidity and disability.

Abstract
Targeting tumor necrosis factor alpha (TNF-alpha) has offered an additional therapeutic strategy against several rheumatic inflammatory disorders. The current use of TNF-alpha inhibitors allows physicians who manage these diseases and patients themselves to testify to an extraordinary efficacy, even though caution for possible adverse events must be maintained. Among these, the occurrence of autoimmune phenomena, encompassing new autoantibody formation and triggering of clinical manifestations, continues to be noted in published reports. Here, we review the current knowledge regarding the autoimmune phenomena linked to anti-TNF-alpha therapy in patients with rheumatic inflammatory disorders.

Abstract
Etanercept is a dimeric fusion protein based on the p75 TNF-alpha receptor. It binds to TNF-alpha and blocks its biologic activity. In randomized, double-blind, placebo-controlled trials, etanercept has therapeutic activity in rheumatoid arthritis, psoriatic arthritis, polyarticular-course juvenile idiopathic arthritis and ankylosing spondylitis. Etanercept improves joint inflammation, physical function and slows/halts structural damage, especially when combined with methotrexate. A sustained response is observed in a substantial percentage of patients. Although some safety issues should be considered before starting etanercept treatment, in general terms, etanercept is a well tolerated drug with an acceptable safety profile. The use of any TNF-alpha antagonist must be in agreement with the National Recommendations for Biologic Therapy, and in difficult clinical situations, a balance between risk/benefit needs to be obtained.

Abstract
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.

Abstract
To evaluate ANA specificity using the fully automated multiplexed fluorescent microsphere immunoassay in patients affected either by rheumatoid arthritis or ankylosing spondylitis who developed strong positivity for ANA as assessed by indirect immunofluorescent method on HEp-2 cells during infliximab treatment. Three men affected by ankylosing spondylitis and 12 women affected by rheumatoid arthritis who developed ANA positivity at high titres during infliximab treatment underwent the identification of ANA specificity by multiplexed fluorescent microsphere immunoassay; moreover anti-DNA and anti-ENA antibodies were tested by indirect immunofluorescence and ELISA method, respectively. In 4 out of 15 cases, the determination of ANA reactivity by multiplexed fluorescent microsphere immunoassay was also performed on the serum collected before infliximab administration. One patient affected by rheumatoid arthritis showed multiple ANA reactivities against SS-A, SS-B, RNP, Sm, Jo-1 and histones; one patient affected by ankylosing spondylitis resulted positive for the same autoantibodies, except for anti-Sm antibody. Moreover, two patients, one with rheumatoid arthritis and one with ankylosing spondylitis, showed single antibody specificity to SS-B and RNP, respectively. The remaining 11 cases did not show any positivity. Instead, all the patients resulted negative for anti-ENA antibodies by the ELISA method. In the four cases tested for ANA specificity by multiplexed fluorescent microsphere immunoassay before and after infliximab administration no difference was found. The search for anti-DNA antibody always resulted negative by both the traditional immunofluorescent assay and the novel technique. The use of multiplexed fluorescent microsphere immunoassay in patients treated with infliximab with ANA positivity at high titres allowed to find some ANA specificities which were not revealed by ELISA method. Nevertheless, the majority of patients resulted negative in spite of ANA positivity at high titres; the molecular target of ANA which develop after infliximab administration still remains to be identified.

Abstract
In recent years, an explosion of biologic response modifiers has entered the market to combat a variety of immune-mediated diseases. These can be in the form of recombinant cytokines, as in the case of interferon beta in the treatment of multiple sclerosis, or novel engineered antibodies constructed by combining non-human determinants with a human immunoglobulin scaffold, as in the case of omalizumab in the treatment of allergic asthma. More recently, completely human monoclonal antibodies have also been constructed. Adverse reactions related to these agents can be classified as expected or unexpected events. A number of case studies and a handful of randomized trials have demonstrated the potential toxicities with the use of biologic response modifiers. This article aims to review adverse event profiles of select biologic response modifiers for which the most data is available and are common to a rheumatology, allergy/immunology, and dermatology patient population.

Abstract
We report a case of a 45-year-old man with an 8-month history of rheumatoid arthritis, who was treated with hydroxychloroquine 400 mg per day and 15 mg intramuscular methotrexate per week without reaching a good control of the disease. The patient was successfully treated with 3 mg/kg infliximab for 20 weeks. Before the last infusion, drug-induced lupus (DIL) was diagnosed based on the clinical features of fever > 37.5 degrees C, recurrence of active synovitis, myalgia, erythematosus rash, pericardial and pleural effusion, and of some laboratory findings (antinuclear antibodies 1:160 and anti double-strand DNA positive by DNA recombinant plasmid assay dsDNA). After infliximab discontinuation and the beginning of therapy with methylprednisolone, lupus symptoms resolved within 6 weeks. A new rheumatoid arthritis flare, occurring after 8 weeks, was controlled by methotrexate plus leflunomide. We also review the development of antinuclear and antidouble-strand DNA antibodies and drug-induced lupus in patients treated with anti-TNFalpha agents (infliximab, etanercept, and adalimumab).

Abstract
PURPOSE OF REVIEW The anti-tumor necrosis factor agents are now widely used in the management of patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile inflammatory arthritis. One of the most common observations made during their use is the development of autoantibodies. The purpose of this paper is to review this phenomenon and its clinical implications. RECENT FINDINGS While the development of different autoantibodies is a common encounter, rare cases of lupus-like syndromes have been reported. On the other hand, a variety of immune-mediated clinical manifestations have been described, including vasculitis and demyelinating syndromes. Rare cases of cytopenia and non-specific lung injuries have also been reported. SUMMARY While these clinical complications are rare and isolated events, clinicians must be aware of their occurrence. The experience with the anti-tumor necrosis factor agents is rather short and new, unusual immune-mediated complications may still appear. Clinicians should be prepared to recognize them.

Abstract
Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disease, which continues to cause significant morbidity in affected persons. In the past few years, a number of new exciting therapeutic options have become available. These reflect the application of knowledge obtained from advancements in understanding of disease pathogenesis and underlying molecular mechanisms. A number of these therapies are outlined in the following review, including the various biological modifiers, in particular, anti-tumour necrosis factor-alpha agents and interleukin-1 (IL-1) receptor antagonists, which have been developed in recognition of the role of pro-inflammatory cytokines in RA. Also notable, is the current interest centring on the development and trials with B cell depletion therapies, specifically rituximab, in patients with RA. This demonstrates acknowledgment for a more significant role for B cells in the aetiology of RA, in contrast to the long held view that RA was a predominantly T cell mediated disease. To evaluate this therapeutic option for RA, salient features from recent rituximab trials have been collated. Finally, a selection of other therapeutic alternatives, including anti-IL-6 receptor monoclonal antibody and tacrolimus, and newer anti-rheumatic therapies presently in development are summarized.

Abstract
To evaluate antibodies against cyclic citrullinated peptides (anti-CCP) together with rheumatoid factor (RF), antinuclear antibodies (ANA) and C-reactive protein (CRP), in patients affected by rheumatoid arthritis (RA), before and after infliximab treatment. Twenty-seven patients (five men and 22 women, mean age of 51.9 years, mean duration of disease 12.6 years) affected by RA, refractory to conventional DMARDs, were treated with infliximab, at the conventional dosage. Before starting infliximab and after 22 weeks, on the occasion of the fifth infusion, anti-CCP antibodies were tested by ELISA method. At the same time IgM RF, ANA and CRP level were measured. Before infliximab therapy, anti-CCP antibodies resulted positive in 23 patients (85.1%); the serum level did not change after infliximab treatment; only one case negative at baseline became slightly positive after treatment. Before and after therapy RF resulted positive in 22 cases (81.4%) and 21 cases (77.7%) respectively; comparing values at baseline with those after 22 weeks of treatment with infliximab, RF levels significantly decreased, as well as CRP values. In contrast to both anti-CCP antibodies, which remained stable, and to RF, which fell after infliximab, ANA were positive > or = 1: 160 in four cases at baseline and in 12 after treatment. The titre of anti-CCP antibodies did not significantly change after anti-TNFalpha blocker administration; instead the positivity of RF significantly decreased. As opposed to antinuclear and anti-dsDNA antibodies, which may appear or increase in titre during infliximab treatment, the typical autoantibodies detectable in RA show a different trend; in fact, anti-CCP antibodies remained stable and RF decreased.

Abstract
Systemic lupus erythematosus (SLE) is an autoantibody and immune complex mediated disease. However, it is the ensuing inflammatory process that leads to irreversible organ damage. In fact several murine models of SLE suggest that this inflammatory organ damage can be prevented even in the presence of autoantibodies. Given data from experimental models as well as from patients, proinflammatory cytokines including tumour necrosis factor (TNF) alpha apparently play a significant role in the inflammatory process, but may have immunoregulatory functions at the same time. Therefore, anti-TNF alpha therapy may constitute an interesting candidate approach for treating SLE inflammatory organ disease, but potentially at the cost of increased autoantibody formation. Clinical trials will be required to answer whether TNF alpha blockade fulfils this hope with an acceptable safety profile. Interferon (IFN)-gamma, interleukin (IL)-18, IL-6 and possibly IL-1 are increased in SLE and likewise involved in the inflammatory process. Specific therapeutic agents for blocking these cytokines should be available in the near future.

Abstract
OBJECTIVE Tumor necrosis factor (TNF)-neutralizing agents are the most successful means of ameliorating systemic autoimmune inflammation. Neutralization of TNF, however, is often associated with the development of autoantibodies, particularly to nuclear antigens, and the mechanisms of this are unknown. We undertook this study to analyze the effect of TNF and its neutralization on the expression of major histocompatibility complex class II molecules and on the function of antigen-presenting myeloid cells in rheumatoid arthritis (RA). METHODS Monocytes were isolated from the peripheral blood of RA patients before and after anti-TNF monoclonal antibody (mAb) treatment and from the peripheral blood of controls by negative selection, differentiated in vitro to macrophages, and analyzed by flow cytometry for HLA-DR expression. T cell responses to activation by myeloid cells were assessed in proliferation assays, and messenger RNA (mRNA) levels of the class II transactivator (CIITA) were determined by semiquantitative reverse transcriptase-polymerase chain reaction. RESULTS HLA-DR expression was significantly reduced on myeloid cells from RA patients with active disease, but was increased to normal levels after anti-TNF mAb treatment. Concordantly, in vitro application of TNF to monocytes from healthy individuals reduced their ability to up-regulate HLA-DR during differentiation to macrophages and, importantly, inhibited their ability to stimulate T cells in mixed lymphocyte reactions. Molecular analysis revealed that the effect of TNF on HLA-DR expression was mediated via suppression of the transcription factor CIITA. CONCLUSION The data indicate that TNF decreases HLA-DR expression by reducing CIITA mRNA levels in myeloid cells, functionally resulting in a decreased capacity of myeloid cells to stimulate T cells. Concordantly, ameliorating disease activity in chronic inflammatory diseases by neutralizing TNF restores expression of HLA-DR on myeloid cells as well as the ability of myeloid cells to stimulate T cells. Thus, anti-TNF treatment might lead to augmented T cell activation by myeloid cells, thereby promoting immune responses to (auto)antigens and the development of antinuclear antibodies that are frequently associated with anti-TNF therapy.

Abstract
The aim of the study was to evaluate a panel of autoantibodies in patients affected by rheumatoid arthritis (RA) treated with anti-TNFalpha blockers, and to consider a different autoantibody induction effect by infliximab and etanercept; and in addition to evaluate in these cases a relationship between antinuclear antibody (ANA) titre and both C-reactive protein (CRP) and Blys levels. Fifty-four patients (8 men, 46 women, mean age 51.4 years, mean duration of disease 13.6 years) affected by refractory RA were treated with anti-TNFalpha blockers for 12 consecutive months; 43 patients were given infliximab and 11 etanercept. At baseline and every 4 months a panel of autoantibodies consisting of rheumatoid factor, antinuclear, anti-double-stranded DNA, anti-ENA, anti-mitochondrial, anti-thyroid and anti-neutrophil cytoplasmic antibodies (ANCA) was tested. At the same time CRP level was measured. Blys level was determined at baseline and after 1 year in five cases that developed a strong positivity for ANA during infliximab therapy. In 41 cases (95.3%) treated with infliximab, ANA were detected on at least one occasion, and in almost half of these cases the titre was very high, equal to or higher than 1:1.280. On the other hand, patients treated with etanercept presented ANA positivity in a lower percentage of cases and at a low titre. No correlation was found between ANA titre and CRP level; Blys level did not present a constant trend in patients who developed a very high positivity for ANA. Anti-double-stranded DNA, anti-thyroid or ANCA were found only in a few patients, in the absence of a clinical picture indicative of systemic lupus erythematosus, autoimmune thyroiditis or ANCA-associated vasculitis. A different incidence of ANA positivity was found in infliximab- and etanercept-treated RA patients; this finding might be due to the partially different method of inhibition of TNFalpha between the two drugs. Both CRP and Blys do not seem to participate in this phenomenon. Other autoantibodies were detected in a few patients, but no case of onset of new autoimmune disorders was observed.

Abstract
Among the numerous idiopathic immune-mediated diseases that can be drug-induced, such as pemphigus, psoriasis, lichen, etc, drug-induced lupus is the most widely commented upon and investigated. The terms drug-induced lupus (DIL) and drug-induced lupus erythematosus (DILE) are preferred, but other ones are also used--drug-related lupus, lupus-like syndrome, and lupus erythematosus medicamentosus. This review discusses the general issues in DILE, such as pathogenic mechanisms, clinical forms, and diagnostic criteria, and provides more detailed information for some of the implicated drugs: minocycline, statins, terbinafine, etc.

Abstract
PURPOSE OF REVIEW The introduction of tumor necrosis factor-alpha antagonists in 1998 has had a significant impact on the treatment of rheumatoid arthritis. However, as use of these agents has increased worldwide, infrequent adverse events that were not apparent in pivotal controlled clinical trials required for registration have emerged. RECENT FINDINGS These adverse events include serious infections, particularly tuberculosis, which may be atypical in presentation. Concern regarding increased risk of lymphoma has also emerged, although it remains unclear whether the risk exceeds that observed in other rheumatoid arthritis patients with comparable disease activity. Development of a systemic lupus erythematosus-like syndrome, which typically abates after discontinuation of the drug, is another rare complication that was further reported during the past year. Finally, additional cases of congestive heart failure and demyelinating syndromes (including cases resembling progressive multifocal leukoencephalopathy) have been reported that appear to be related to the tumor necrosis factor-alpha antagonists. SUMMARY Additional postmarketing surveillance of these and other serious adverse events is necessary to determine the true risk of their occurrence, and whether a reassessment of the overall risk-benefit of tumor necrosis factor-alpha antagonists will be required.

Abstract
The aim of the present study was to investigate the effect of long-term infliximab treatment on various autoantibodies in patients with rheumatoid arthritis. Serum samples from 30 consecutive patients, who were prospectively followed during infliximab and methotrexate therapy for refractory rheumatoid arthritis, were tested at baseline and after 30, 54 and 78 weeks. At these points, median values of the Disease Activity Score were 6.38 (interquartile range 5.30-6.75), 3.69 (2.67-4.62), 2.9 (2.39-4.65) and 3.71 (2.62-5.06), respectively. Various autoantibodies were assessed by standard indirect immunofluorescence and/or ELISA. Initially, 50% of patients were positive for antinuclear antibodies, and this figure increased to 80% after 78 weeks (P = 0.029). A less marked, similar increase was found for IgG and IgM anticardiolipin antibody titre, whereas the frequency of anti-double-stranded DNA antibodies (by ELISA) exhibited a transient rise (up to 16.7%) at 54 weeks and dropped to 0% at 78 weeks. Antibodies to proteinase-3 and myeloperoxidase were not detected. The proportion of patients who were positive for rheumatoid factor (RF) was similar at baseline and at 78 weeks (87% and 80%, respectively). However, the median RF titre exhibited a progressive reduction from 128 IU/ml (interquartile range 47-290 IU/ml) to 53 IU/ml (18-106 IU/ml). Anti-cyclic citrullinated peptide (CCP) antibodies were found in 83% of patients before therapy; anti-CCP antibody titre significantly decreased at 30 weeks but returned to baseline thereafter. In conclusion, the presence of anti-double-stranded DNA antibodies is a transient phenomenon, despite a stable increase in antinuclear and anticardiolipin antibodies. Also, the evolution of RF titres and that of anti-CCP antibody titres differed during long-term infliximab therapy.

Abstract
Tumour necrosis factor-alpha (TNFalpha) is a proinflammatory cytokine that is synthesised by a variety of cell types in response to infectious or inflammatory stimuli. Although TNFalpha plays an adaptive role in immune protection and wound healing at 'physiological' levels, excess TNFalpha production can lead to adverse consequences. TNFalpha is a pivotal cytokine involved in the pathogenesis and progression of rheumatoid arthritis (RA). TNFalpha antagonists have been shown to be effective in the treatment of signs and symptoms of RA and the US FDA has approved three TNFalpha antagonists, etanercept, infliximab, and most recently, adalimumab, for the treatment of RA. However, differences have emerged, with respect to their demonstrated efficacy in other diseases (e.g. Crohn's disease). Worldwide, over half a million patients have been treated with TNFalpha antagonists and concerns regarding their safety have been raised. There is a risk of reactivation of granulomatous diseases, especially tuberculosis, with all three agents and appropriate measures should be taken for detection and treatment of latent infections. An association between non-Hodgkin's lymphoma and treatment with TNFalpha antagonists has been reported, although patients with active, long-standing RA are already known to have an increased incidence of non-Hodgkin's lymphoma. No associations with solid tumours have been found to date. The biological plausibility of lymphomas associated with immunomodulatory agents raises concern and vigilance is appropriate until the relationship is fully characterised. Large phase II and III trials have shown a detrimental effect of TNFalpha antagonists in advanced heart failure and these agents should be avoided in this population. Rare case reports of drug-induced lupus, seizure disorder, pancytopenia and demyelinating diseases have been noted after TNFalpha antagonists and continued vigilance is warranted in patients on TNFalpha antagonists for the development of these diseases. At present there is no evidence implicating TNFalpha antagonists with embryotoxicity, teratogenicity or increased pregnancy loss.

Abstract
Cytokines and anticytokines are used increasingly in the treatment of immune, autoimmune, inflammatory, infectious, and malignant disorders. Commonly used treatments include the anti-tumor necrosis factor agents interferon alpha, interferon beta, interferon gamma, and interleukin 2. Several autoimmune phenomena have been reported in patients treated with these substances. This review summarizes the published data on the autoimmune manifestations associated with cytokine and anticytokine therapies, as well as describes possible mechanisms of these phenomena.

Abstract
The definition of PsA is still being refined, as is the understanding of the genetic and immunologic contributors to the pathophysiology of this disease. As knowledge of the underlying immunologic causes of PsA evolves, so too do treatment choices. Conventional therapies with broadly immunosuppressive effects have been the standard of therapy, but the clinical benefits of these agents are often unpredictable and might be limited by their side effects. Newer agents with mechanisms of action targeted toward specific components of the immune cascade are expected to provide more reliable responses with fewer efficacy-limiting side effects than the more conventional agents borrowed from the RA armamentarium. Anti-TNF medicines such as etanercept, the first agent approved specifically for treatment of PsA, are an advance in the treatment of PsA, and other biological agents are on the horizon that might continue to help define the immunopathogenesis of PsA and treat the disease effectively.

Abstract
OBJECTIVE There is increasing evidence that tumor necrosis factor alpha (TNFalpha) is centrally involved in the pathogenesis of ankylosing spondylitis (AS) and other spondylarthritides. This study was designed to investigate the efficacy of anti-TNFalpha therapy with etanercept, a 75-kd receptor fusion protein, in active AS. METHODS This multicenter trial had 2 phases: an initial placebo-controlled period of 6 weeks' duration and an observational phase lasting 24 weeks. Thirty patients with active AS were included. They were randomized into 2 groups, which received either etanercept (25 mg twice weekly) (n = 14) or placebo (n = 16) for 6 weeks. Then both groups were treated with etanercept. Nonsteroidal antiinflammatory drug (NSAID) treatment could be continued, but disease-modifying antirheumatic drugs (DMARDs) and steroids had to be withdrawn prior to the study. All patients received etanercept for a total of 12 weeks and were followed up for at least 24 weeks. The Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index, Bath AS Metrology Index, pain level on a numeric rating scale, quality of life by the Short Form 36, and C-reactive protein (CRP) level were assessed. The primary outcome parameter was a >or=50% improvement in the BASDAI. RESULTS Treatment with etanercept resulted in at least a 50% regression of disease activity in 57% of these patients at week 6, versus 6% of the placebo-treated patients (P = 0.004). After the placebo-treated patients switched to etanercept, 56% improved. The mean +/- SD BASDAI improved from 6.5 +/- 1.2 at baseline to 3.5 +/- 1.9 at week 6 in the etanercept group, with no improvement in the placebo group (P = 0.003 between groups). Similarly, pain, function, mobility, and quality of life improved with etanercept but not with placebo at week 6 (P < 0.05). Mean CRP levels decreased significantly with etanercept but not with placebo (P = 0.001). There was ongoing improvement in all parameters in both groups until week 12 and week 18, respectively (i.e., throughout the period of etanercept treatment). Disease relapses occurred a mean +/- SD of 6.2 +/- 3.0 weeks after cessation of etanercept. No severe adverse events, including major infections, were observed during the trial. CONCLUSION This study shows that on a short-term basis (3 months), treatment with etanercept is clearly efficacious in patients with active AS who are receiving NSAID therapy but not DMARDs or steroids. After cessation of therapy, almost all patients experienced a relapse within a few weeks. Thus, it seems probable that etanercept must be administered continuously in most AS patients to achieve permanent inhibition of the inflammatory process.
