Abstract
In contrast to the original fear that treatment with disease-modifying antirheumatic drugs (DMARDs) and especially with biologic DMARDs (bDMARDs), was associated with an increased risk of the induction of malignancies, this has meanwhile fortunately not been confirmed over the long-term administration. Evaluations from register-based investigations as well as from other long-term cohort studies confirm that neither conventional DMARDs, such as methotrexate, nor tumor necrosis factor (TNF) inhibitors or biologics with a different mode of action show such a risk for induction of cancer or hematological malignancies (for skin tumors see the other article). Regarding the question whether recurrences of former malignancies can be induced by DMARDs, the database is considerably smaller; however, published investigations dealing with this topic so far signal that also in this respect no increased risk can be found. When comparing the individual substances with each other no substantial differences can be found. Although used in the treatment of hematological cancers, rituximab does not offer any advantages in comparison to other biologics. For the group of Janus kinase (JAK) inhibitors, which have been in use only for a few years, data outside the randomized controlled studies (which are limited in time and are conducted with a selected patient population) are limited so that a clear statement regarding the malignancy risk is not yet possible for these substances. In a solitary study comparing tofacitinib with TNF inhibitors in high-risk patients, the malignancy risk of the JAK inhibitor was increased compared to that under TNF inhibitor treatment; however, these results have not yet been confirmed by a second investigation.

Abstract
There is an increased risk of malignancies in patients with many systemic rheumatic diseases, which negatively impact on their quality of life. The risk and types of malignancies can differ by the type of rheumatic diseases. Possible mechanisms linking them are dynamic and complicated, including chronic inflammation and damage in rheumatic disease, inability to clear oncogenic infections, shared etiology and some anti-rheumatic therapies. Although certain disease-modifying anti-rheumatic drugs (DMARDs) have been proved to be potentially carcinogenic, the majority of them were not associated with increased risk of most malignancies in patients with systemic rheumatic diseases.

Abstract
Autoimmune diseases (ADs) are at a significantly higher risk of cancers with unclear mechanism. By searching GWAS catalog database and Medline, susceptible genes for five common ADs, including systemic lupus erythematosus (SLE), rheumatoid arthritis, Sjögren syndrome, systemic sclerosis, and idiopathic inflammatory myopathies, were collected and then were overlapped with cancer driver genes. Single-cell transcriptome analysis was performed in the comparation between SLE and related cancer. We identified 45 carcinogenic autoimmune disease risk (CAD) genes, which were mainly enriched in T cell signaling pathway and B cell signaling pathway. Integrated single-cell analysis revealed immune cell signaling was significantly downregulated in renal cancer compared with SLE, while stemness signature was significantly enriched in both renal cancer or lymphoma and SLE in specific subpopulations. Drugs targeting CAD genes were shared between ADs and cancer. Our study highlights the common and specific features between ADs and related cancers, and sheds light on a new discovery of treatments.

Abstract
Rheumatoid arthritis (RA) is a multi-system autoimmune disease with significant morbidity and healthcare burden. It is an inflammatory condition and has been associated with lymphomas, with or without the presence of immunosuppressive therapy. However, the association of rheumatoid arthritis with other malignancies has been inconsistent. We used the data from a population-based National Health and Nutrition Examination Survey (NHANES) for epidemiological study to evaluate the association between RA and the incidence of cancer. Using the data collected between 2011 and 2014, we were able to determine the incidence of cancer in 11,262 patients. Incidence of cancer was increased in patients with RA with an odds ratio of 1.632 (95% confidence interval [CI]: 1.239-2.151; p=0.0005). Breast cancer (CA) and prostate CA were the most common types of cancer (each diagnosed in 16.22% individuals) and lung CA and lymphomas found in 1.35% of individuals. It is also important to be aware of increased risk and adequately screen patients for malignancies during the course of treatment and follow up of rheumatoid arthritis. Further large prospective studies are required to determine the association of the RA or its treatment and the risk of malignancies.

Abstract
Methotrexate (MTX) is the first line drug for the treatment of a number of rheumatic and non-rheumatic disorders. It is currently used as an anchor disease, modifying anti-rheumatic drug in the treatment of rheumatoid arthritis (RA). Despite the development of numerous new targeted therapies, MTX remains the backbone of RA therapy due to its potent efficacy and tolerability. There has been also a growing interest in the use of MTX in the treatment of chronic viral mediated arthritis. Many viruses-including old world alphaviruses, Parvovirus B19, hepatitis B/C virus, and human immunodeficiency virus-have been associated with arthritogenic diseases and reminiscent of RA. MTX may provide benefits although with the potential risk of attenuating patients' immune surveillance capacities. In this review, we describe the emerging mechanisms of action of MTX as an anti-inflammatory drug and complementing its well-established immunomodulatory activity. The mechanisms involve adenosine signaling modulation, alteration of cytokine networks, generation of reactive oxygen species and HMGB1 alarmin suppression. We also provide a comprehensive understanding of the mechanisms of MTX toxic effects. Lastly, we discussed the efficacy, as well as the safety, of MTX used in the management of viral-related rheumatic syndromes.

Abstract
Methotrexate (MTX) is used as an anchor disease-modifying anti-rheumatic drugs (DMARDs) in treating rheumatoid arthritis (RA) because of its potent efficacy and tolerability. MTX benefits a large number of RA patients but partially suffered from side effects. A variety of side effects can be associated with MTX when treating RA patients, from mild to severe or discontinuation of the treatment. In this report, we reviewed the possible side effects that MTX might cause from the most common gastrointestinal toxicity effects to less frequent malignant diseases. In order to achieve regimen with less side effects, the administration of MTX with appropriate dose and a careful pretreatment inspection is necessary. Further investigations are required when combining MTX with other drugs so as to enhance the efficacy and reduce side effects at the same time. The management of MTX treatment is also discussed to provide strategies for occurred side effects. Thus, this review will provide scholars with a comprehensive understanding the side effects of MTX administration by RA patients.

Abstract
In kidney transplant recipients, cancer is one of the leading causes of death with a functioning graft beyond the first year of kidney transplantation, and malignancies account for 8-10% of all deaths in the USA (2.6 deaths/1000 patient-years) and exceed 30% of deaths in Australia (5/1000 patient-years) in kidney transplant recipients. Patient-, transplant- and medication-related factors contribute to the increased cancer risk following kidney transplantation. While it is well established that the overall immunosuppressive dose is associated with an increased risk for cancer following transplantation, the contributive effect of different immunosuppressive agents is not well established. In this review we will discuss the different risk factors for malignancies after kidney transplantation.

Abstract
UNLABELLED Autoimmune disease (AD) is common in patients with Wiskott-Aldrich syndrome (WAS) and patients with WAS who has an AD usually constitute a high-risk group with poor outcome. However, knowledge of AD in WAS is limited in China. In this study, medical records of 53 patients with WAS at Children´s Hospital of Chongqing Medical University from April 2004 to January 2014 were evaluated retrospectively and 14 patients (26%) had at least one AD. Autoimmune hemolytic anemia (AIHA) was the most common and detected in 12 patients (23%), other complications included immune thrombocytopenia (n = 1), immune neutropenia (n = 1), autoimmune arthritis (n = 1), and renal injury (n = 1). No significant differences were found in the level of serum immunoglobulins and lymphocyte subsets between the AD group and non-AD group. Although eight patients with AD received hematopoietic stem cell transplantation (HSCT), three patients died of pulmonary infection after HSCT. CONCLUSIONS AD is frequent in Chinese patients with WAS and AIHA was the most common. AD is a poor prognosis factor for WAS and should be treated as early as possible by HSCT. WHAT IS KNOWN • Autoimmune disease is common in patients with WAS. • Manifestations, follow-up finding, and treatment approaches of autoimmune disease in Chinese patients with WAS have received less attention in the literature. What is New: • This study is firstly intended for evaluation of the clinical and immune characteristics of autoimmune disease in a large series Chinese patients with WAS. • AD is frequent in Chinese patients with WAS and AIHA is the most common.

Abstract
Methotrexate (MTX) is the anchor disease-modifying antirheumatic drug (DMARD) in rheumatoid arthritis (RA) treatment. It is used in monotherapy and/or in combination with other synthetic or biological DMARDs, and is known to have the best cost-effectiveness and efficacy/toxicity ratios. However, toxicity is still a concern, with a significant proportion of patients interrupting long-term treatment due to the occurrence of MTX-related adverse drug reactions (ADRs), which are the main cause of drug withdrawal. Despite the extensive accumulated experience in the last three decades, it is still impossible in routine clinical practice to identify patients prone to develop MTX toxicity. While clinical and biological variables, including folate supplementation, partially help to minimize MTX-related ADRs, the advent of pharmacogenomics could provide further insight into risk stratification and help to optimize drug monitoring and long-term retention. In this paper, we aimed to review and summarize current data on low-dose MTX-associated toxicity, its prevention and predictors, keeping in mind practical RA clinical care.

Abstract
BACKGROUND The effects of extra-intestinal cancer on the course of inflammatory bowel disease (IBD) are poorly understood. AIM To evaluate the impact of cancer and its management on IBD outcomes. METHODS A total 80 IBD patients (51 Crohn's disease, 29 ulcerative colitis; 33 men, median age at cancer diagnosis 48yrs) diagnosed with extra-intestinal cancer were selected from a prospective database. IBD activity and therapeutic requirements (assessed year-by-year) were compared before and after cancer diagnosis, with a control group of patients without cancer matched for gender, birth date, date of IBD diagnosis and IBD phenotype. RESULTS Paired comparisons of the consecutive periods before and after cancer diagnosis did not show significant changes in median (IQR) percentages of years with active disease (27% [0-50] vs. 19% [0-53]), while the proportion of patient-years on any immunosuppressant remained stable (26% vs. 28%). Chemotherapy had no significant effect on IBD activity. Compared to controls, patients with cancer had a similar IBD activity and use of anti-TNF, but less use of immunomodulators (19% vs. 25%, p<0,001) and an increased rate of surgery (4% vs. 2.5%, p<0,05). Individual variations in IBD activity after cancer diagnosis were not significantly different in patients with cancer and their matched controls. CONCLUSION Occurrence of extra-intestinal cancer impacts IBD therapeutic management, with a trend towards less use of immunomodulators and more surgery. In the long-term, cancer diagnoses and treatments do not modify IBD outcomes.

Abstract
The association between rheumatoid arthritis (RA) and cancer is still controversial. This study aimed to estimate cancer incidence (both overall and site-specific) among patients with RA and to determine whether their cancer risk was higher than in the general population. We used the nationwide dynamic cohort from the National Health Insurance Research Database of Taiwan and obtained a total of 30,504 patients with no history of cancer who were newly diagnosed with RA between 1996 and 2008; they were followed up until 2010. Standardized incidence ratios (SIR) by age for various types of cancer were calculated in 5-year calendar periods by 5-year age intervals (quinquinquennium) to compare elevated risk of increasing age and increased cancer rate in later calendar years in Taiwan. During 225,432 person-years of follow-up, 1,595 cancers occurred, corresponding to 7.08 per 1,000 person-years. The SIR for all cancers was 0.93 (95 % CI 0.88-0.97). Most cancers were found in the first 2 years after diagnosis of RA, but the incidence decreased afterward. A significant excess of Hodgkin's lymphoma (SIR 3.31, 95 % CI 1.24-8.81) and non-Hodgkin's lymphoma (SIR 3.18, 95 % CI 2.64-3.83) was seen among patients with RA, whereas the risk of colorectal cancer was 29 % lower than the general population. In conclusion, this study showed that patients with RA do not have increased overall risk of cancers but have higher risk of hematologic malignancies and lower risk of colorectal cancer, than the general population.

Abstract
The purpose of this study is to review the literature on the risk of malignancy in patients with inflammatory eye disease (IED) treated with systemic immunosuppressive (IS) therapy. Relevant databases in transplant medicine, autoimmune diseases and literature regarding uveitis and scleritis were reviewed. Literature with regards systemic IS therapy in transplant recipients and patients with autoimmune diseases revealed a significant increase in malignancies, especially non-melanocytic skin cancers and lymphomas. Studies of patients with IED were limited in number and scope, with no studies adequately evaluating the incidence of malignancy in these patients. Difficulties associated with the evaluation of the risk of malignancy associated with IS therapy in patients with IED include the heterogeneity of the disease and treatment regimens as well as the low frequency of IED, its variable severity and the lack of adequate long-term follow-up studies. Systemic IS therapy is an important therapeutic option in the treatment of patients with severe IED. A well-designed, comprehensive, multi-centre long-term follow-up study is required to evaluate the risk of malignancy in patients with specific IED diseases treated with defined systemic IS therapy. Until such evidence is available, we recommend the adoption of preventative strategies to help minimise the risk of malignancy in such patients.

Left lower limb ultrasound, computed tomography and positron emission tomography scans showed extensive lymphadenopathy. Core biopsies of the left groin, axilla and nipple lesion showed this to be concurrent diffuse B-cell lymphoma and locally metastatic invasive ductal carcinoma of the breast. He underwent a left mastectomy with axillary clearance, and adjuvant fluorouracil, epirubicin and cyclophosphamide chemotherapy with rituximab, and the adalimumab was stopped. CONCLUSIONS The findings from our patient's case should increase awareness that patients with severe rheumatoid arthritis, especially if they are on high-dose biological treatments, have the potential to develop lymphoma, which in turn increases the risk of developing other primary tumors, so that in rare cases a patient may have concurrent tumors. Assessment and management of these patients is challenging and should include computed tomography scans of the of neck, thorax, abdomen and pelvis, including a fludeoxyglucose positron emission tomography/computed tomography scan, bone marrow testing and appropriate core biopsies and discussion at multidisciplinary team meetings about treatment of the separate tumors in the presence of hematologists, oncologists, surgeons and rheumatologists.

Abstract
The relationship between non-steroidal anti-inflammatory drug (NSAID) use and esophageal squamous cell carcinoma (ESCC) has remained unclear. To evaluate the relationship between NSAID use and risk of ESCC, we searched the MEDLINE, Biosis, Web of Science and ISI proceedings databases up to September 2010, together with a manual search of reference lists of relevant articles. Studies evaluating the association between exposure to NSAIDs and risk of ESCC were included. The analyses used random-effect or fixed-effect model based on homogeneity analysis. Seven studies (six case-control studies and one nested case-control study) were included in this meta-analysis. NSAID use was associated with a reduced risk of ESCC (odds ratio = 0.58, 95% confidence interval = 0.47 to 0.72). Specific analysis for aspirin and non-aspirin NSAIDs yielded similar results. There was a protective association between NSAIDs and ESCC. This finding warrants more prospective studies evaluating the relationship between NSAIDs and ESCC.

Abstract
Management of patients with inflammatory rheumatic disease and a history of (or even a current) malignant disease poses some particular challenges. As direct evidence of the risk of (recurrent or de novo) malignancy in patients with a history of malignant disease is scarce, such a risk may be estimated indirectly from the principal carcinogenicity of the respective drug to be used or (also indirectly) from cancer reactivation data from the transplant literature. In general, cancer risk is increased in patients receiving combination immunosuppressive treatment, but the risk in patients receiving individual drugs (with the exception of alkylating agents) remains entirely unclear. Indirect evidence supports the intuitive concept that the risk of cancer decreases over time after a successful cancer treatment. The only two studies in rheumatic patients with a cancer history were small and have not been able to show an increase in cancer reactivation. The risk of reactivation also depends on the site and location of the prior malignancy. In conclusion, the decision to treat a patient with a history of cancer immunosuppressively should be shared by the rheumatologist and the oncologist. Once the decision is established, such patients need intensive and close monitoring.

Abstract
OBJECTIVE It is unclear if skin cancer risk is affected by the use of immunomodulatory medications in rheumatoid arthritis (RA), psoriasis, and psoriatic arthritis (PsA). The purpose of this study is to evaluate and summarize the available data pertinent to this question. METHODS The English language literature on PubMed was searched with a combination of phrases, including "malignancy," "skin cancer," "squamous cell carcinoma," "basal cell carcinoma," "melanoma," "psoriasis," "psoriatic arthritis," and "rheumatoid arthritis" in addition to the generic names of a variety of common immunomodulatory drugs. Relevant articles were identified and data were extracted. RESULTS In total, 2218 potentially relevant articles were identified through the search process. After further screening, 20 articles relevant to RA were included. An additional 19 articles relevant to either psoriasis or PsA were included as well. RA may be a risk factor for the development of cutaneous malignancy. Treatment with tumor necrosis factor inhibitors increases the rates of non-melanoma skin cancer (NMSC) in RA and psoriasis. This risk doubles when combination methotrexate therapy is used in RA. Methotrexate may increase the risk of malignant melanoma in patients with RA and the risk of NMSC in psoriasis. Cyclosporine and prior phototherapy significantly increase the risk of NMSC. CONCLUSION RA may potentiate the risk of cutaneous malignancy and therefore dermatologic screening in this population should be considered. The use of immunomodulatory therapy in RA, psoriasis, and PsA may further increase the risk of cutaneous malignancy and therefore dermatologic screening examinations are warranted in these groups. More careful recording of skin cancer development during clinical trials and cohort studies is necessary to further delineate the risks of immunomodulatory therapy.

Abstract
Juvenile idiopathic arthritis (JIA) includes several forms of chronic arthritis in children. Treatments are chosen according to the type and severity of the disease. Nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids remain the mainstays of therapy. Traditional slower acting anti-rheumatic drugs, such as gold therapy, penicillamine, sulfasalazine, tiopronin and hydroxychloroquine, are usually poorly active in children. In addition, adverse effects are common, including severe macrophage activation syndrome with gold therapy or sulfasalazine. Low dose, once weekly methotrexate has emerged as the therapeutic agent of choice for children who fail to respond adequately to the administration of an NSAID, especially in those with the extended oligoarticular subtype of the disease. Other immunosuppressive agents, such as cyclosporin, are sometimes combined with methotrexate. In recent years, novel treatments have been developed. Autologous hematopoietic stem cell transplantation is effective in a number of children with severe JIA, whose disease has been refractory to conventional therapy. However, only short term follow-up data are currently available for this novel therapy. In addition, severe infections complicated by macrophage activation syndrome and death have been reported. Finally, anti-tumour necrosis factor-alpha therapy has shown efficacy in more than two-thirds of children with JIA and polyarthritis, and other cytokine inhibitors may be soon available.

Abstract
OBJECTIVE The objective of this retrospective cohort study was to evaluate cancer risk among rheumatoid arthritis (RA) patients in California. METHODS The study cohort derived from statewide patient discharge records was followed via linkage with cancer registry data over the period 1991-2002. Age and sex adjusted standardized incidence ratios (SIRs) and 95% confidence intervals were calculated to compare observed to expected numbers of cancers based on age, race, and sex specific incidence rates in the California population. RESULTS Among the 84,475 RA patients, who were observed for 405,540 person-years, 5,533 incident cancers were diagnosed during the observation interval. The risk of developing lymphohematopoietic cancer was significantly higher in the cohort for both sexes. Males had significantly higher risks of lung, liver, and esophageal cancer, but a lower risk of prostate cancer. Females were at significantly decreased risk for several cancers including breast, ovary, uterus, cervix, and melanoma, with the risk reduction ranging from 15 to 57% lower than the general population. Hispanics had increased risks of leukemia, vagina/vulva, lung, and liver cancers. CONCLUSION Studies investigating the mechanisms that underlie the reported associations between RA and specific cancer types are needed.

Long-term risk of malignancy among patients treated with immunosuppressive agents for ocular inflammation: a critical assessment of the evidence. Am J Ophthalmol 2008; 146:802-12.e1.

Abstract
PURPOSE To critically assess potentially carcinogenic effects of immunosuppressive therapy in the ocular inflammation setting. DESIGN Focused evidence assessment. METHODS Relevant publications were identified by MEDLINE and EMBASE queries and reference list searches. RESULTS Extrapolation from transplant, rheumatology, skin disease, and inflammatory bowel disease cohorts to the ocular inflammation setting suggest that: 1) alkylating agents increase hematologic malignancy risk and cyclophosphamide increases bladder cancer risk, but less so with < or =18 months' duration of therapy and hydration, respectively; 2) calcineurin inhibitors and azathioprine probably do not increase total cancer risk to a detectable degree, except perhaps some other risk factors (uncommon in ocular inflammation patients) might interact with the former to raise risk; 3) tumor necrosis factor (TNF) inhibitors may accelerate diagnosis of cancer in the first six to 12 months, but probably do not increase long-term cancer risk; and 4) changes in risk with methotrexate, mycophenolate mofetil, and daclizumab appear negligible, although nontransplant data are limited for the latter agents. Immunosuppression in general may increase skin cancer risk in a sun exposure-dependent manner. CONCLUSION Use of alkylating agents for a limited duration seems justifiable for severe, vision-threatening disease, but otherwise cancer risk may be a relevant constraint on use of this approach. Antimetabolites, daclizumab, TNF inhibitors, and calcineurin inhibitors probably do not increase cancer risk to a degree that outweighs the expected benefits of therapy. Monitoring for skin cancer may be useful for highly sun-exposed patients. Data from ocular inflammation patients are needed to confirm the conclusions made in this analysis by extrapolation.

Abstract
OBJECTIVE To determine cancer risk in a cohort of 459 rheumatoid arthritis (RA) patients treated with methotrexate in community practice. METHODS All RA patients who started methotrexate prior to June 1986 and were attending 1 of 6 rheumatologists were studied. Demographic data were matched to the State Cancer Registry to identify all malignancies (except nonmelanoma skin cancer) for 1983-1998, and to the National Death Index to identify all deaths to the end of 1999. Followup started on the date when methotrexate was started and ended either on the last confirmed date on which the patient was seen by the rheumatologist or at death. Standardized incidence ratios (SIRs) were calculated using state population cancer rates stratified by sex, age (in 5-year groups), and calendar year. RESULTS There were 4,145 person-years of followup (average 9.3 years). Eighty-seven malignancies were identified (14 before, 64 during, and 9 after the followup period). There was an estimated 50% excess risk of malignancy among methotrexate-exposed RA patients relative to the general population (SIR 1.5, 95% confidence interval [95% CI] 1.2-1.9), with a 3-fold increase in melanoma (SIR 3.0, 95% CI 1.2-6.2), a 5-fold increase in non-Hodgkin's lymphoma (SIR 5.1, 95% CI 2.2-10.0), and an almost 3-fold increase in lung cancer (SIR 2.9, 95% CI 1.6-4.8). CONCLUSION Compared with the general population, methotrexate-treated RA patients have an increased incidence of melanoma, non-Hodgkin's lymphoma, and lung cancer. There may be a role for regular skin cancer screening for all RA patients, particularly those receiving immunosuppressive therapy.

Abstract
Psoriasis is a chronic skin disorder affecting up to 2.5% of the world's population. Despite the myriad treatment options available, there is no uniformly accepted therapeutic approach for moderate-to-severe psoriasis. The objective of this review is to evaluate the relative efficacy and safety of available therapeutic options and to formulate general recommendations for the treatment of moderate-to-severe psoriasis. MEDLINE and Evidence Based Medicine (Cochrane) were used to perform a comprehensive search of the literature from 1986 to 2006. The most scientifically rigorous clinical trial published in the literature was selected for Psoriasis Area and Severity Index (PASI 75) comparison. Only information from clinical trials, human subjects and English language journals are reported in this study. The percentage of PASI 75 reduction at approximately 12 weeks obtained by the following treatment options were: Goeckerman and RePUVA, 100%; calcipotriene plus PUVA, 87%; ciclosporin, 78.2-80.3%; infliximab, 80%; adalimumab 40 mg every other week, 53% and 40 mg/week, 80%; PUVA, 63%; methotrexate, 60%; NB-UVB, 55%; acitretin 52%; etanercept 50 mg twice weekly, 49% and 25 mg twice weekly, 34%; efalizumab, 31.4%; and alefacept 21%. Psoriatic treatments with safer profiles compared with other agents include bath PUVA, Goeckerman and RePUVA. Based on the literature review of efficacy and safety of biologics and prebiologic treatment options for moderate-to-severe psoriasis, the risk:benefit ratio seems most favorable for Goeckerman and RePUVA, followed by either etanercept or adalimumab.

Abstract
Juvenile rheumatoid arthritis is a chronic condition. The goal of therapy is to control pain, preserve joint range of motion and function, minimize systemic complications, and assist in normal growth and development. Recent advances in understanding the pathophysiology of arthritis have expanded the treatment of this chronic condition. Many medications including nonsteroidal anti-inflammatory agents, disease-modifying antirheumatic drugs, biologic agents, and cytotoxic agents are available for treating juvenile rheumatoid arthritis. Emergency medicine physicians should be familiar with the different classes and adverse effects of these drugs.

Abstract
Paraneoplastic symptoms, caused by a malignancy, but not directly related to invasion by the tumor or its metastases are the result of a wide variety of tumor-derived biologic mediators like hormones, peptides, antibodies, cytotoxic lymphocytes, autocrine and paracrine mediators. Recognition of paraneoplastic syndromes is important, as it may lead to an early diagnosis of cancer. There is some evidence that systemic inflammatory diseases, such as rheumatoid arthritis (RA), lupus, scleroderma or dermatomyositis may increase the risk for the development of malignancies, predominantly lymphoproliferative disorders. However, reports are somewhat controversial. Immunosuppressive and cytotoxic drugs used in antirheumatic therapy, such as methotrexate, cyclophosphamide, azathioprine or anti-TNF biologicals may also lead to the development of such tumors. Tumor-associated antigens may be produced by inflammatory cells and their production may be increased in RA and other autoimmune diseases.

Abstract
Malignancy is a well defined complication of chronic immunosuppression. Post transplant malignancies appear to be related to cumulative doses of immunosuppression, and in pediatric patients, acute infection of previously naive patients. The most commonly encountered malignancy in this age population is Post Transplant Lymphoproliferative Disorder (PTLD). PTLD is not a single entity but rather represents a continuum of disease. Treatment of PTLD should be initiated with immunosuppression reduction. Standard dose chemotherapy leads to significant morbidity. With the introduction of anti-CD20 antibody treatment with rituximab, chemotherapy has become second line therapy. The occurrence of solid malignancy appears to be associated with chronic immunosuppression. These cancers include those of skin, gynecologic organs, and the rectum, all of which appear to have the strongest association with viral mediators. Several strategies have been postulated to minimize the occurrence of malignancy. These include ganciclovir prophylaxis for the prevention of PTLD and the use of mychophenolic acid and TOR inhibitor maintenance to diminish the incidence of PTLD and solid malignancies. This leaves transplant physicians with several new and novel immunosuppressive agents with uncertain oncologic potentials that will need to be examined over the next decade.

Abstract
Methotrexate is used increasingly in low-dose regimes for a variety of conditions, particularly rheumatoid arthritis. While certain adverse effects of low-dose methotrexate have been described in detail, oral complications have received little attention. This article includes a summary of the uses and pharmacology of low-dose methotrexate and the mechanisms that lead to general and oral toxicity. The literature relevant to potential oral adverse effects is discussed and 7 illustrative cases are presented. The oral effects noted range from nonhealing ulcers to lymphoma-like lesions. Dental practitioners should be aware of the possible oral effects of low-dose methotrexate that have so far been largely unrecognized.

Abstract
As newer immunosuppressive regimens have steadily reduced the incidence of acute rejection and have extended the life expectancy of allograft recipients, posttransplant malignancy has become an important cause of mortality. In fact, it is expected that cancer will surpass cardiovascular complications as the leading cause of death in transplant patients within the next 2 decades. An understanding of the underlying pathobiology and how to minimize cancer risks in transplant recipients are essential. The etiology of posttransplant malignancy is believed to be multifactorial and likely involves impaired immunosurveillance of neoplastic cells as well as depressed antiviral immune activity with a number of common posttransplant malignancies being viral-related. Although calcineurin inhibitors and azathioprine have been linked with posttransplant malignancies, newer agents such as mycophenolate mofetil and sirolimus have not and indeed may have antitumor properties. Long-term data are needed to determine if the use of these agents will ultimately lower the mortality due to malignancy for transplant recipients.

Abstract
Over the last decade, several new drugs have become available for the treatment of patients with rheumatoid arthritis. These agents include the new disease-modifying antirheumatic drug (DMARD) leflunomide and the biologic agents, tumor necrosis factor (TNF)-alpha antagonists and an interleukin (IL)-1 receptor antagonist. Methotrexate is commonly used as the first DMARD, has a well documented clinical efficacy and slows radiological deterioration. Sulfasalazine appears to have similar properties, albeit to a lesser extent. Leflunomide has similar efficacy as methotrexate but it is less tolerated than sulfasalazine. The adverse effect profiles of these three drugs makes regular laboratory monitoring mandatory. Several combination therapies with DMARDs were proven to be more effective than mono-DMARD therapy. However, until now these strategies have not been widely adopted. TNF antagonists are potent anti-inflammatory drugs, with a rapid onset of effects compared with traditional DMARDs. The IL-1 receptor antagonist, anakinra, has an intermediate place between methotrexate and the TNF antagonists with respect to efficacy. The adverse effects of TNF antagonists include an increased incidence of common and opportunistic infections. Thus far, anakinra has not been associated with an enhanced rate of opportunistic infections. Some of the biologic agents have been associated with worsening heart failure and demyelinating disease. The limited long-term safety data of the biologic agents are a point of concern because, at present, an enhanced risk for malignancies, particularly lymphoma, can not be excluded. Drug costs of traditional DMARDs are up to US dollars 3000 per year, whereas for the biologics the yearly drug costs range between US dollars 16,000 and > US dollars 20,000. Cost-effectiveness analyses are necessary to determine whether or not these high costs are justified. Unfortunately, adequate, prospective, economic evaluations are not yet available. Until these become available, treatment decisions will be based on the balance of direct costs and indirect costs and expected cost savings in the future.

Abstract
In recent years there has been a surge of interest in the treatment of chronic inflammatory disorders as a result of the development and application of targeted biological therapies. The elucidation of the overlapping cellular and cytokine immunopathology of such diverse conditions as rheumatoid arthritis (RA), Crohn's disease, and psoriasis points to specific targets for bioengineered proteins or small molecules. Similar to clinical trials in RA, trials in psoriatic arthritis (PsA) have shown excellent clinical results with the tumour necrosis factor (TNF) blockers, etanercept, infliximab, and adalimumab in a variety of domains including the joints, quality of life, function, and slowing of disease progress as evidenced radiologically. In addition, these agents have shown benefit in domains more unique to PsA, such as the skin lesions of psoriasis, enthesitis, and dactylitis, pointing out the similar pathogenesis of the disease in the skin, the tendons, and the synovial membrane. This therapy has been generally safe and well tolerated in clinical trials of PsA. Other logical candidates for targeted therapy in development include other anti-TNF agents, costimulatory blockade agents that affect T cell function, blockers of other cytokines such as interleukin (IL)-1, 6, 12, 15, or 18, and B cell modulatory medicines. Also, it will be useful to learn more about the effects of combining traditional disease modifying drugs and the newer biologicals.

Abstract
The treatment of rheumatoid arthritis (RA) has changed dramatically over the past 15 years with the realisation that earlier, aggressive therapy limits progression. There is evidence that biological response modifiers (BRMs), which target specific cytokines such as TNF-alpha and IL-1, are more effective than traditional disease-modifying antirheumatic drugs (DMARDs), especially in combination with methotrexate. Four therapies are approved for use in RA; three target TNF-alpha (etanercept [Enbrel, Amgen Inc.], infliximab [Remicade, Centocor Inc.], and adalimumab [Humira, Abbott]), and one targets IL-1 (anakinra [Kineret, Amgen Inc.]). It is clear from both the clinical trials and postmarketing reports that all four agents have a different safety profile compared with traditional DMARDs. There are several areas of concern with the use of the BRMs, which include serious and opportunistic infections, malignancy/lymphoma, congestive heart failure, demyelination, injection/infusion reactions, development of autoantibodies and lupus-like disease. It is important to be fully aware of the safety profile and differences between BRMs in order to use them appropriately.

Abstract
Tumor necrosis factor (TNF) antagonists are biologic response modifiers that have significantly improved the outcomes in patients with rheumatoid arthritis (RA). At this report, safety data were collected on approximately 271,000 patients administered infliximab (as of February 2002), 121,000 patients administered etanercept (as of December 2001), and on 2400 patients who received adalimumab in trials in connection with the regulatory approval process (approval granted December 2002 in the US and September 2003 in European Union). Infliximab and etanercept have predictable and manageable safety profiles, and preliminary data suggest that the profile of adalimumab is comparable. Safety issues involving the anti-TNF agents as a class include the risk of injection-site reactions or infusion-related reactions, infection (for example, serious, opportunistic, or tubercular), malignancy, autoimmunity, and demyelinating and neurologic disorders. Injection-site and infusion-related reactions are most often easily managed and rarely lead to discontinuation of therapy. Infections can be minimized or prevented by screening and careful monitoring and follow-up; most infections respond to appropriate medical treatment. More studies are needed to evaluate the occurrence of malignancies in patients with RA to determine the potential risk posed by therapy. Antibody formation can follow the administration of any biologic agent. Although demyelinating disease has been reported with anti-TNF agents, it is not clear whether a causal relationship exists. Overall, the anti-TNF agents are well tolerated and have demonstrated a favorable benefit-to-risk profile in patients with RA.

Abstract
OBJECTIVE To assess and characterise the risk of bladder cancer, and its relation to cyclophosphamide, in patients with Wegener's granulomatosis. METHODS In the population based, nationwide Swedish Inpatient Register a cohort of 1065 patients with Wegener's granulomatosis, 1969-95, was identified. Through linkage with the Swedish Cancer Register, all subjects in this cohort diagnosed with bladder cancer were identified. Nested within the cohort, a matched case-control study was performed to estimate the association between cyclophosphamide and bladder cancer using odds ratios (ORs) as relative risk. In the cohort the cumulative risk of bladder cancer after Wegener's granulomatosis, and the relative prevalence of a history of bladder cancer at the time of diagnosis of Wegener's granulomatosis, were also estimated. RESULTS The median cumulative doses of cyclophosphamide among cases (n = 11) and controls (n = 25) were 113 g and 25 g, respectively. The risk of bladder cancer doubled for every 10 g increment in cyclophosphamide (OR = 2.0, 95% confidence interval (CI) 0.8 to 4.9). Treatment duration longer than 1 year was associated with an eightfold increased risk (OR = 7.7, 95% CI 0.9 to 69). The absolute risk for bladder cancer in the cohort reached 10% 16 years after diagnosis of Wegener's granulomatosis, and a history of bladder cancer was (non-significantly) twice as common as expected at the time of diagnosis of Wegener's granulomatosis. CONCLUSION The results indicate a dose-response relationship between cyclophosphamide and the risk of bladder cancer, high cumulative risks in the entire cohort, and also the possibility of risk factors operating even before Wegener's granulomatosis.

Abstract
There are many complex associations between rheumatoid arthritis(RA) and malignancy. Patients with rheumatic diseases on the whole appear to be at increased risk for the development of certain malignancies. The data from several studies are persuasive that the presence of RA conveys an increased risk for the development of lymphoproliferative disorders and may convey a decreased risk for the development of malignancies of the digestive tract. Understanding the complex interrelationships between RA and malignancy will lead to more accurate diagnosis of underlying pathology, more effective treatment of symptoms and underlying disease, and appropriate surveillance for the development of later complications.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs), including aspirin, seem to have chemopreventive properties against several types of cancer, particularly colon cancer. Persons with rheumatoid arthritis, an autoimmune disease for which NSAIDs are used commonly, have been reported to be at lower risk of colon cancer but at elevated risk of non-Hodgkin lymphoma (NHL), raising the possibility that NSAIDs may be a risk factor for NHL. We evaluated the association of use of NSAIDs, arthritis history, and risk of NHL in a prospective cohort of 27,290 postmenopausal women from the state of Iowa. The frequency of use of aspirin and of other NSAIDs excluding aspirin (e.g., ibuprofen), as well as a physician diagnosis of rheumatoid arthritis (RA) or osteoarthritis (OA), were self-reported on a questionnaire mailed in 1992. The incidence of NHL was ascertained through annual linkages to the Iowa SEER Cancer Registry. Relative risks (RR) and 95% confidence intervals (CI) were estimated using Cox proportional hazards regression. Through 7 years of follow-up, 131 cases of NHL were identified. Compared to women who did not use either aspirin or other non-aspirin NSAIDs, women using aspirin exclusively (RR = 1.71; 95% CI = 0.94-3.13), non-aspirin NSAIDs exclusively (RR = 2.39; 95% CI = 1.18-4.83), or both types of drugs (RR = 1.97; 95% CI = 1.06-3.68) were at increased risk of NHL. A diagnosis of RA (RR = 1.75; 95% CI = 1.09-2.79), but not OA (RR = 1.06; 95% CI = 0.67-1.68), was associated with risk of NHL, but the positive association of use of aspirin and other NSAIDs with NHL was independent of RA history. Multivariate adjustment for other NHL risk factors only attenuated slightly these associations, whereas exclusion of cases occurring during the first 2 years of follow-up strengthened the associations. These data suggest that use of NSAIDs, either aspirin or other non-aspirin NSAIDs, are associated positively with risk of NHL, and that this association is independent of RA history.

Abstract
As many as 40% of patients with Wiskott-Aldrich syndrome may eventually suffer from an autoimmune disorder, with an increased chance of developing a malignancy. Vasculitides and autoimmune hemolytic anemia are the two most common autoimmune manifestations and often cause considerable morbidity and mortality, because they may require treatment with bone marrow transplantation. Insights into the mechanisms of autoimmunity have provided clues to the pathogenesis of these disorders in Wiskott-Aldrich syndrome. Chronic inflammation, interleukin-2 deficiency, and increased apoptosis may all play a possible role in the loss of peripheral tolerance to self-antigens in this disease. This article reviews the manifestations and consequences of autoimmunity in Wiskott-Aldrich syndrome, its possible mechanisms, and available treatments.

Abstract
Low dose pulse methotrexate (LDMTX) therapy has become effective in the treatment of autoimmune and lymphoproliferative diseases. The pharmacokinetics of LDMTX is individually highly variable, resulting in a different systemic exposure to the drug and a variable therapeutic/toxic effect in patients. The improvements and exacerbations of disease activity in relation to the introductions and discontinuations of LDMTX therapy suggest the possible immunosuppresive and anti-inflammatory properties of the drug. Because of a strong correlation between the drug pharmacokinetics and the therapeutic outcomes (pharmacodynamics), it seems to be possible to individualise the LDMTX therapy according to the results of pharmacokinetic/pharmacodynamic analysis. In the case of psoriasis, pharmacokinetic/pharmacodynamic analysis in our local study revealed a highly significant inverse relationship between PASI (expressed as a percent of the initial value) and a steady-state AUC(MTX) (area under the curve of methotrexate plasma concentrations; r(8) = -0.65, p < 0.001). The considerable inter-individual variability and low intra-individual variability in MTX pharmacokinetics, supports a role for therapeutic monitoring and dose individualisation at the start of pharmacotherapy. The results of this study suggest that a steady-state AUC(MTX) value of 700 nmol x h/L and higher are associated with a significantly better success rate of antipsoriatic therapy than lower values. The preliminary results in our follow-up study suggest the statistically higher incidence of unwanted effects depending on maximum plasma concentration of the drug. Moreover, statistically significant correlation was found between the toxic effects and exposure to the drug regarding methotrexate plasma concentrations and intracellular storage in erythrocytes. However, the data are still in the process of being completed and are not yet published.

Abstract
Rheumatoid arthritis (RA) is an autoimmune arthritis, for which treatment options remain limited. This study investigated the potential role of adoptive cellular gene therapy as a novel means for treating the RA animal model collagen-induced arthritis (CIA). Adoptive transfer of antigen-specific T-cell hybridomas retrovirally transduced to express IL-4 1 day before booster immunization significantly reduced the number of inflamed joints. Cell transfer after clinical onset of disease had no therapeutic effect. Bioluminescence imaging showed that the hybridomas migrated to the inflamed joints, thus delivering the regulatory protein locally at the site of inflammation. The homing was, at least in part, due to chemotaxis in response to proinflammatory chemokines that are expressed in inflamed joints. There were no significant changes in the cytokine milieu of the draining lymph nodes, nor in the systemic levels of anti-collagen antibodies in treated mice. We conclude that the beneficial clinical effects observed in our model were most likely based on the local action(s) of IL-4 in the inflamed joints and that the local delivery (and effects) of regulatory cytokines, like IL-4, constitutes a novel and effective method of preventing organ-specific autoimmune disease and of minimizing systemic adverse effects.

Abstract
BACKGROUND As knee implants become more common, it is important to study their potential health risks. We investigated cancer occurrence in a nationwide population-based cohort of 30,011 patients who underwent knee replacement surgery in Sweden from 1980 to 1994. METHODS Patients were followed from 1 year after the date of their surgery through December 31, 1995, accruing 122,616 person-years of observation. The average follow-up time was 4.3 years, with 2365 patients followed for 10 years or more. RESULTS Overall cancer incidence was not elevated compared with the general population of Sweden (standardized incidence ratio [SIR] = 1.03; 95% confidence interval [CI] = 0.98-1.08). A reduced rate for all respiratory cancers (SIR = 0.73; 95% CI = 0.59-0.91) and for lung cancer (SIR = 0.73; 95% CI = 0.58-0.91) was found among both men and women. Elevated rates were found for prostate (SIR = 1.20; 95% CI = 1.06-1.34) and bone cancer (SIR = 6.00; 95% CI = 1.24-17.52) in men. The bone cancer excess was based on three observed cases, two of which occurred at a site unrelated to the implant and the site of the third tumor is unknown. Rates of connective tissue cancer and leukemia-lymphoma were not elevated significantly among knee implant recipients. Long-term follow-up (>or= 10 years) did not show a significant excess risk for all cancer (SIR = 1.10; 95% CI = 0.86-1.38) or for any site-specific cancer, including bone cancer, lymphoma, or leukemia. Subgroup analyses for patients with rheumatoid arthritis produced results similar to the overall results. CONCLUSIONS This epidemiologic study of cancer risk among patients with knee implants is the largest to date. It provides evidence that the incidence of cancer among patients with knee implants is similar to that of the general population. Continued follow-up of this cohort is warranted to evaluate further potential long-term effects of these implants.
