Abstract
Novel technology is one of the five focus areas of the Challenges in Inflammatory Bowel Disease (IBD) Research 2024 document. Building off the Challenges in IBD Research 2019 document, the Foundation aims to provide a comprehensive overview of current gaps in IBD research and deliver actionable approaches to address them with a focus on how these gaps can lead to advancements in interception, remission, and restoration for these diseases. The document is the result of a multidisciplinary collaboration from scientists, clinicians, patients, and funders and represents a valuable resource for patient-centric research prioritization. Specifically, the Novel Technologies section focuses on addressing key research gaps to enable interception and improve remission rates in IBD. This includes testing predictions of disease onset and progression, developing novel technologies tailored to specific phenotypes, and facilitating collaborative translation of science into diagnostics, devices, and therapeutics. Proposed priority actions outlined in the document include real-time measurement of biological changes preceding disease onset, more effective quantification of fibrosis, exploration of technologies for local treatment of fistulas, and the development of drug delivery platforms for precise, location-restricted therapies. Additionally, there is a strong emphasis on fostering collaboration between various stakeholders to accelerate progress in IBD research and treatment. Addressing these research gaps necessitates the exploration and implementation of bio-engineered novel technologies spanning a spectrum from materials to systems. By harnessing innovative ideas and technologies, there's a collective effort to enhance patient care and outcomes for individuals affected by IBD.

Stasik K, Filip R. The Complex Relationship between Mechanisms Underlying Inflammatory Bowel Disease, Its Treatment, and the Risk of Lymphomas: A Comprehensive Review. Int J Mol Sci 2024; 25:4241. [PMID: 38673824 PMCID: PMC11049907 DOI: 10.3390/ijms25084241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 04/06/2024] [Accepted: 04/08/2024] [Indexed: 04/28/2024] Open
Abstract
Patients with inflammatory bowel disease may be at higher risk of developing lymphomas and other cancers of the gastrointestinal tract. In addition, there may be a link between the use of thiopurines or anti-tumor necrosis factor drugs (anti-TNF) and these pathologies. The treatment of patients with Crohn's disease who have previously been diagnosed with lymphoma is a challenge for gastroenterologists. In this report, we examine important clinical issues related to the treatment of patients with inflammatory bowel disease with active lymphoma, as well as of patients with hematological cancer history. In this discussion, we take into account most of the available treatments for inflammatory bowel disease, as well as the impact of chronic inflammation and viral infections. In addition, we try to find common ground for the development of lymphoproliferative disorders and autoimmune diseases. Patients with inflammatory bowel disease may be at higher risk of developing lymphomas and other cancers of the gastrointestinal tract. Chronic inflammatory processes and viral infections play an important role in carcinogenesis. In addition, there may be a link between the use of thiopurines or anti-TNF drugs and these pathologies. A significant risk of the development of lymphoma in people undergoing each therapy should be considered, and it should be estimated how much greater this risk will be in patients with a history of lymphoproliferative disorders. The following review is an attempt to answer which therapy would be the most appropriate for patients with Crohn's disease and a history of lymphoma treatment. A lack of clear guidelines creates great challenges for doctors.

Abstract
Introduction Over the past 20 years, the increasing use of combined therapy with immunosuppressants and biologic agents has markedly reduced the use of steroids in the management of inflammatory bowel diseases (IBD). However, medical therapy seems to promote, in the long run, carcinogenesis resulting in an increased risk of developing different types of malignancies, including lymphomas. The aim of this study was to systematically review the current incidence and prognosis of lymphoid neoplasms occurring in patients with IBD. Methods Studies analyzing the incidence of lymphomas in subjects of age >18 years affected by IBD were included in this systematic review and meta-analysis. Studies focusing on pediatric populations, not reporting person-years of follow-up, or with a duration < 1 year were excluded. PubMed, Embase, Web of Science Core Collection, and Cochrane Central Register were searched from inception through January 2022. Publication bias within studies was assessed using Begg's and Egger's tests and random effects model. Quantitative results were synthesized using relative-risk meta-analysis. PRISMA guidelines were used to carry out this systematic review (PROSPERO Registration Number: CRD42023398348). Results A total of 345 studies published between 1985 and 2022, with a total of 6,17,386 patients were included in the meta-analysis. Substantial heterogeneity between studies prevented the pooling of estimates (I2 = 97.19%). Evidence of publication bias was overall low (p = 0.1941). Patients affected by Crohn's disease (CD) were 1,86,074 (30.13%), while 2,78,876 (46.17%) were diagnosed with UC. The remaining 23.7% of cases were diagnosed with indeterminate colitis. Immunomodulators and biologic therapy were used in 24,520 (5.27%), and 17,972 (3.86%) patients, respectively. Reported incidence rates for lymphoma in IBD ranged from 0.0/100,000 person/years (py) (95% CI 0.0-3.7/100,000) to 89/100,000 py (95% CI 36-160/100,000). Reported incidence rates of lymphoma in CD ranged from 0.0/100,000 py (95% CI 0.0-3.7/100,000) to 91/100,000 py (95% CI 18-164/100,000). For UC, the incidence rate ranged from 0.0/100,000 py (95% CI 0.0-3.7/100,000) to 95/100,000 py (95% CI 0-226/100,000). Male-to-female ratio was ~4:1. Therapy with immunomodulators was directly associated with an increased incidence of lymphoma (p < 0.0001). Evidence of publication bias was overall low (p = 0 .1941). Conclusions The evidence arising from this study highlights a correlation between the use of immunomodulators and subsequent lymphoma development. Combined multidisciplinary approach and long-term follow-up are warranted in order to decrease mortality deriving from the coexistence of both conditions.

Abstract
Abstract
Background
Recent guidelines recommended judicious use of abdominal computed tomography (CT) in the emergency department (ED) for inflammatory bowel disease. Trends in CT utilization over the last decade, including since the implementation of these guidelines, remain unknown.
Methods
We performed a single-centre, retrospective study between 2009 and 2018 to assess trends in CT utilization within 72 h of an ED encounter. Changes in the annual rates of CT imaging among adults with IBD were estimated by Poisson regression and CT findings by Cochran-Armitage or Cochran-Mantel Haenszel tests.
Results
A total of 3000 abdominal CT studies were performed among 14,783 ED encounters. CT utilization increased annually by 2.7% in Crohn’s disease (CD) (95% confidence interval [CI], 1.2 to 4.3; P = 0.0004), 4.2% in ulcerative colitis (UC) (95% CI, 1.7 to 6.7; P = 0.0009) and 6.3% in IBD unclassifiable (95% CI, 2.5 to 10.0; P = 0.0011). Among encounters with gastrointestinal symptoms, 60% with CD and 33% with UC underwent CT imaging in the final year of the study. Urgent CT findings (obstruction, phlegmon, abscess or perforation) and urgent penetrating findings alone (phlegmon, abscess or perforation) comprised 34% and 11% of CD findings, and 25% and 6% of UC findings, respectively. The CT findings remained stable overtime for both CD (P = 0.13) and UC (P = 0.17).
Conclusion
Our study demonstrated persistently high rates of CT utilization among patients with IBD who presented to the ED over the last decade. Approximately one third of scans demonstrated urgent findings, with a minority demonstrating urgent penetrating findings. Future studies should aim to identify patients in whom CT imaging is most appropriate.

Abstract
BACKGROUND Patients with inflammatory bowel disease are at increased risk of extracolonic cancers. Little is known regarding this risk following total colectomy [TC]. METHODS Patients who underwent TC for inflammatory bowel disease in Denmark during 1977-2013 were identified from the Danish National Patient Registry. Incidence rates of extracolonic cancers were determined through record linkage to the Danish Cancer Registry and compared with expected incidence rates in the general population. Standardized incidence ratios [SIRs] were calculated as the observed vs expected cancer incidence. RESULTS In total, 4430 patients (3441 with ulcerative colitis [UC]; 989 with Crohn's disease [CD]) were followed for 54,183 person-years after TC. Following their surgery, 372 patients were diagnosed with extracolonic cancer compared to 331 expected [SIR = 1.1 (95% confidence interval {CI}: 1.0-1.2)]. The risk of extracolonic cancer overall was increased among patients with CD and TC (SIR = 1.5 [95% CI: 1.2-1.8]), but not among patients with UC and TC (SIR = 1.0 [95% CI: 0.9-1.2]). Patients with UC and TC had a higher risk of intestinal extracolonic cancer (SIR = 2.0 [95% CI: 1.4-2.7]). Patients with CD and TC had a higher risk of smoking-related cancers (SIR = 1.9 [95% CI: 1.2-2.9]), intestinal extracolonic cancer (SIR = 3.1 [95% CI: 1.6-5.5]) and immune-mediated cancers (SIR = 1.5 [95% CI: 1.0-2.1]). CONCLUSION Patients with CD and TC had a higher risk of extracolonic cancer overall compared to the general population, while patients with UC and TC did not. Site-specific cancer risk varied according to inflammatory bowel disease type.

Modified Pfannenstiel Open Approach as an Alternative to Laparoscopic Total Proctocolectomy and IPAA: Comparison of Short- and Long-term Outcomes and Quality of Life. Dis Colon Rectum 2018; 61:573-578.

Abstract
BACKGROUND A laparoscopic approach to total proctocolectomy with IPAA has been suggested to have better short-term outcomes and cosmesis, whereas open surgery by midline incision may result in shorter operative times. We hypothesized that a modified Pfannenstiel open approach would combine the advantages of both techniques. OBJECTIVE The purpose of this study was to compare outcomes of open total proctocolectomy with IPAA using a modified Pfannenstiel incision versus those following the laparoscopic approach. DESIGN This was a retrospective study comparing patients submitted to open IPAA using modified Pfannenstiel incision versus laparoscopy from 1998 to 2014. SETTINGS The study was conducted at a high-volume tertiary referral center. PATIENTS Among 1275 patients, 119 patients underwent the laparoscopic approach and 33 underwent the modified Pfannenstiel approach. MAIN OUTCOME MEASURES Short- and long-term outcomes were evaluated, and quality-of-life questionnaires were assessed. RESULTS Patients who underwent the modified Pfannenstiel approach were younger, more often women, and had lower BMI and ASA classification compared with those who underwent laparoscopy. Surgical time was lower in Pfannenstiel, and no difference was observed in length of hospital stay. No difference was observed in postoperative complications, pouch failure rate, or quality of life. Patients were then matched 1:1 by diagnosis, sex, age (±5 y) and BMI (±5 kg/m). The Pfannenstiel approach still had a shorter surgical time. No difference was observed in the length of hospital stay, complications, pouch failure, or quality of life. In long-term follow-up, pouchitis symptoms occurred more frequently in Pfannenstiel (mean follow-up = 7.3 y), and seepage was more frequently observed in the laparoscopy group (mean follow-up = 4.2 y). These differences were not observed in matched patients. LIMITATIONS The study was limited by its retrospective design and inherent selection bias. CONCLUSIONS The modified Pfannenstiel approach provides equivalent short- and long-term outcomes and similar quality of life compared with laparoscopy but with a significantly shorter operative time. The modified Pfannenstiel approach to total proctocolectomy with IPAA may be the most efficient method in selected patients. See Video Abstract at http://links.lww.com/DCR/A562.

Abstract
The population of older patients with inflammatory bowel disease (IBD) continues to grow, partly reflecting the aging global population in general. The debilitating effects of IBD compound age-related decrements in health and functional capacity, and make the medical management of older patients with Crohn's disease and ulcerative colitis distinctly challenging to clinicians. Here, we review the recent literature describing the pharmacologic management of IBD in this population, with focus on the safety, tolerability, and efficacy of common treatment options, such as steroids, immunomodulators, tumor necrosis factor-α antagonists, and integrin antagonists; surgical interventions in older patients are also discussed. Few studies have systematically and prospectively evaluated the clinical challenges in the medical management of IBD in this patient population, leaving a limited evidence base to which clinicians can turn to for guidance. Treatment patterns may thus be suboptimal. For example, prolonged steroid use in the elderly was found to be common, causing significant morbidity from side effects in a particularly vulnerable population. Finally, within the context of a limited evidence base, we discuss common treatment scenarios to define the parameters within which physicians can individualize care for older patients with IBD. Overall, older patients with IBD are at higher risk of adverse events and less treatment responsiveness compared with younger patients, underscoring the need for future studies to fully characterize appropriate treatment courses for this population.

Abstract
The inflammatory response is a highly regulated process, and its dysregulation can lead to the establishment of chronic inflammation and, in some cases, to death. Inflammation is the cause of several diseases, including rheumatoid arthritis, inflammatory bowel diseases, multiple sclerosis, and asthma. The search for agents inhibiting inflammation is a great challenge as the inflammatory response plays an important role in the defense of the host to infections. Marine invertebrates are exceptional sources of new natural products, and among those diterpenoids secondary metabolites exhibit notable anti-inflammatory properties. Novel anti-inflammatory diterpenoids, exclusively produced by marine organisms, have been identified and synthetic molecules based on those structures have been obtained. The anti-inflammatory activity of marine diterpenoids has been attributed to the inhibition of Nuclear Factor-κB activation and to the modulation of arachidonic acid metabolism. However, more research is necessary to describe the mechanisms of action of these secondary metabolites. This review is a compilation of marine diterpenoids, mainly isolated from corals, which have been described as potential anti-inflammatory molecules.

Abstract
The medical treatment for inflammatory bowel disease (IBD) has improved over the past 20 years. Although the routine use of immunomodulators and biologic agents in the treatment of IBD in the modern era has been a great achievement, these medicines are associated with rare but serious adverse events. In addition to the infectious complications, there are data to suggest that some of these agents are associated with higher rates of malignancy. In a patient with a history of cancer, or a family history of cancer, the gastroenterologist must be prepared to answer questions about the oncogenic potential of these agents. Thiopurines have been associated with a small increased risk of lymphoma in patients with IBD. In addition, an association with skin cancer has been established. Methotrexate is generally considered safe in patients with a history of cancer. There may be a small risk of lymphoma and possibly skin cancer with anti-tumor necrosis factor agents, but determining the cancer risk of these medications is difficult as they are often used in combination with thiopurines. In general, a family history of cancer should not influence a patient's medical regimen. Treatment for a patient with a personal history of cancer must be individualized and take into account the type and stage of cancer, time since completion of therapy, and the opinion of an oncologist.

Abstract
Adalimumab (ADA) is a tumor necrosis factor (TNF) inhibitor, used for the treatment of inflammatory bowel disease. Previous studies have reported an increased risk of cancer following exposure to TNF inhibitors, but little has been reported for patients with cancer receiving TNF-inhibitor treatment. We present a female patient with metastatic breast cancer and ulcerative colitis (UC) who was treated with ADA. A 54-year-old African American female with a past history of left-sided breast cancer (BC) diagnosed at age 30 was initially treated with left-breast lumpectomy, axillary dissection, followed by chemotherapy and radiation therapy. Years after initial diagnosis, she developed recurrent, bilateral BC and had bilateral mastectomy. Subsequent restaging computed tomography (CT) scan demonstrated distant metastases to the bone and lymph nodes. Three years into her treatment of metastatic breast cancer, she was diagnosed with UC by colonoscopy. Her UC was not controlled for 5 mo with 5-aminosalicylates. Subcutaneous ADA was started and resulted in dramatic improvement of UC. Four months after starting ADA, along with ongoing chemotherapy, restaging CT scan showed resolution of the previously seen metastatic lymph nodes. Bone scan and follow-up positron emission tomography/CT scans performed every 6 mo indicated the stability of healed metastatic bone lesions for the past 3 years on ADA. While TNF-α inhibitors could theoretically promote further metastases in patients with prior cancer, this is the first report of a patient with metastatic breast cancer in whom the cancer has remained stable for 3 years after ADA initiation for UC.

Abstract
Background/Aims Recently, several studies have revealed that diagnostic imaging can result in exposure to harmful levels of ionizing radiation in inflammatory bowel disease patients. However, the extent of radiation exposure in intestinal Behcet disease (BD) patients has not been documented. The aim of this study was to estimate the radiation exposure from abdominal imaging studies in intestinal BD patients. Methods Patients with a diagnosis of intestinal BD established between January 1990 and March 2012 were investigated at a single tertiary academic medical center. The cumulative effective dose (CED) was calculated retrospectively from standard tables and by counting the number of abdominal imaging studies performed. High exposure was defined as CED >50 mSv. Results In total, 270 patients were included in the study. The mean CED was 41.3 mSv, and 28.1% of patients were exposed to high levels of radiation. Computed tomography (CT) accounted for 81.7% of the total effective dose. In multivariate analyses, predictors of high radiation exposure were azathioprine/6-mercaptopurine use, surgery, and hospitalization. Conclusions Approximately a quarter of intestinal BD patients were exposed to harmful levels of diagnostic radiation, mainly from CT examination. Clinicians should reduce the number of unnecessary CT examinations and consider low-dose CT profiles or alternative modalities such as magnetic resonance enterography.

Abstract
Inflammation and cancer have a profound yet ambiguous relationship. Inflammation - especially chronic inflammation - has protumorigenic effects, but inflammatory cells also mediate an immune response against the tumor and immunosuppression is known to increase the risk for certain tumors.This article reviews current literature on the role of inflammation in cancer and the cancer risk in immune-mediated inflammatory diseases (IMIDs). We discuss the effect on cancer risk of different drug classes used in the treatment of IMIDs treatment, including biologicals such as tumor necrosis factor (TNF) inhibitors.Overall cancer incidence and mortality risk are similar to the general population in inflammatory bowel disease (IBD), and slightly increased for rheumatoid arthritis and psoriasis, with risk profiles differing for different tumor types. Increased risk for non-melanoma skin cancer is associated with thiopurine treatment in IBD, with the combination of anti-TNF and methotrexate in rheumatoid arthritis and with PUVA, cyclosporine and anti-TNF treatment in psoriasis. Data on the safety of using biologic or immunosuppressant therapy in IMID patients with a history of cancer are scarce.This review provides clinicians with a solid background to help them in making decisions about treatment of immune-mediated diseases in patients with a tumor history.This article is related to another review article in Molecular Cancer: http://www.molecular-cancer.com/content/12/1/86.

Abstract
BACKGROUND Several recent studies have revealed that diagnostic imaging can result in exposure to potentially harmful levels of ionizing radiation in patients with inflammatory bowel disease (IBD). However, these studies have been conducted exclusively in Western countries, and no data are available in Asian populations. The aim of this study was to estimate the diagnostic radiation exposure in Korean patients with IBD and to determine the factors associated with high radiation exposure. METHODS Patients with an established diagnosis of IBD between July 1987 and January 2012 were investigated in 13 university hospitals in Korea. The cumulative effective dose (CED) was calculated retrospectively from standard tables. RESULTS A total of 777 patients with Crohn's disease (CD) and 1422 patients with ulcerative colitis (UC) were included in the study. The mean CED for CD and UC were 53.6 and 16.4 mSv, respectively (P < 0.001). CTof CD and UC accounted for 81.6% and 71.2% of total effective dose, respectively. Importantly, 34.7% of patients with CD and 8.4% of patients with UC were exposed to high levels of radiation (CED > 50 mSv) (P < 0.001). High radiation exposure was associated with long disease duration, ileocolonic disease, upper gastrointestinal tract involvement, surgical intervention, hospitalization, and the requirement for oral steroids in CD, and with surgical intervention, hospitalization, and the requirement for infliximab in UC. CONCLUSIONS A substantial proportion of patients with IBD, especially patients with CD, were exposed to significantly harmful amounts of diagnostic radiation, mainly as a result of CT examination. Given that IBD is a life-long illness, strategies to reduce radiation exposure from diagnostic imaging need to be considered.

Abstract
Introduction. Although the role of TNF-α in tumor development is not fully understood, an increased risk of malignancy with TNF-α-inhibitors, such as infliximab, has been suggested. Case Presentation. We present a 54-year-old nonsmoking female sarcoidosis patient. After seven months of infliximab therapy a T1aN0M0 larynx carcinoma of the right vocal cord was found and excised. Within a year, whilst still on treatment, a second larynx carcinoma of the opposite vocal cord appeared. Discussion. A bilateral vocal cord tumor is rare, especially in a never smoker. Evidence on the role of infliximab in carcinogenesis is inconclusive. To date, there are no follow-up studies evaluating malignancy risk of infliximab therapy in sarcoidosis patients. No studies in other diseases focus on laryngeal carcinomas during infliximab use. We argue that infliximab treatment might have attributed to the rapid progression of vocal cord carcinomas in this patient with an a priori low risk tumor profile. This case illustrates that caution remains warranted in patients with previous malignancies when considering initiation of TNF-α-inhibitors.

Abstract
BACKGROUND Anti-tumour necrosis factor (TNF) agents, through their intense immunoregulatory effect, have been suspected to increase the risk of malignant lymphoma. However, the classical epidemiological approaches conducted over about the last 10 years have not totally succeeded in addressing the question of a causal or artifactual association. Therefore, the analysis of a substantial set of case reports, although usually considered as poorly generalizable to the general population, could be particularly informative. Two main sources of case reports in postmarketing settings are available; publications in medical journals and reports to pharmacovigilance systems. OBJECTIVE The aim of the study was to compare the characteristics of case reports from both these sources in order to understand whether they provided the same information for the investigation of the causal link between lymphoma and anti-TNF agents. METHODS All case reports of malignant lymphoma in patients treated with an anti-TNF agent published in MEDLINE and all reports to the French pharmacovigilance system up to 1 February 2010 were identified. Cases of malignant lymphoma identified in postmarketing surveillance from both sources were compared regarding the following variables: age, sex, anti-TNF agent involved, indication for use, type of lymphoma, prior or concomitant immunosuppressive drugs and time to onset of lymphoma. RESULTS A total of 81 published case reports and 61 cases reported to the French pharmacovigilance system were compared. In published reports, patients were younger (p = 0.03) and more frequently receiving a first anti-TNF treatment (p = 0.03), particularly infliximab (p = 0.03). Conversely, in the pharmacovigilance system reports, a succession of different anti-TNFs (p = 0.03) and adalimumab (p < 0.0001) were more frequently reported. Lymphomas in patients treated with anti-TNF agents for Crohn's disease were more prevalent in published cases than in pharmacovigilance reports (p < 0.0001), and in particular involved hepatosplenic T-cell lymphoma. Conversely, rheumatoid arthritis was the main indication for anti-TNF agents in pharmacovigilance reports (p = 0.01). Time to onset was markedly shorter in published cases (median 12 months) than in pharmacovigilance reports (median 30 months; p = 0.0001). CONCLUSIONS Characteristics of published cases and those reported to the French pharmacovigilance system differed markedly for all characteristics tested, except sex and the use of prior or concomitant immunosuppressive drugs. Published case reports favoured convincing arguments for drug causation whereas cases reported to the pharmacovigilance system were more disparate but could describe more accurately the reality of lymphoma occurrence in this particular population. These results argue for the use of the pharmacovigilance reports when case reports are used to investigate the causal link between lymphoma and anti-TNF agents at the population level. Data from cases notified to the French pharmacovigilance system did not indicate an increased risk of lymphoma during the early phase of anti-TNF treatment. To confirm this hypothesis, a study combining pharmacovigilance reports from several countries, or, if feasible, a cohort study both with a large sample size and a long duration of follow-up would be required.

Abstract
Lymphoma is an increasingly recognized complication of tumor necrosis factor (TNF) inhibition for the treatment of autoimmune and inflammatory disease; the majority of these cases are non-Hodgkin lymphomas (NHL). The impact of withdrawing TNF inhibition therapy in cases of lymphoma is not well described. A woman with Crohn's disease (CD) was diagnosed with Hodgkin lymphoma (HL) and subsequently went into remission with standard chemotherapy. Her CD later worsened, requiring initiation of adalimumab, a TNF inhibitor. Ten months later, she was found to have recurrence of HL. When she opted against additional treatment for the lymphoma, the TNF inhibitor was discontinued. Three months later, the measurable sites of disease had completely regressed. It can be concluded that HL is a potential complication of treatment with TNF inhibitors. Withdrawal of immunosuppression may be a consideration for patients treated for lymphoproliferative disorders including HL. Maintenance of an intact immune system may be important for prevention of lymphoma relapse. Further understanding of this complex interaction will help clinicians determine in which patients these agents have a favorable risk-benefit ratio.

Abstract
Tumor necrosis factor α (TNF-α) antibody agents are an effective therapy for the treatment of inflammatory bowel disease (IBD); however, because of the potential for immune suppression with these drugs, TNF-α antibody agents can increase the risk of malignancy. We report here the case of an 11-year-old boy who presented with bowel obstruction. He also had a history of periodic fever, aphthous stomatitis, and cervical adenitis (PFAPA). Intestinal inflammation continued and impaired his quality of life; he was diagnosed with IBD of an undetermined type (IBD-U). Symptoms improved with infliximab, but he developed elevated transaminase levels with hepatosplenomegaly 1 year after scheduled infusions. Skin biopsy revealed an atypical lymphoid infiltrate consistent with an Epstein-Barr virus (EBV)-positive natural killer (NK)/T-cell lymphoma with associated hemophagocytic lymphohistiocytosis. Bone marrow biopsy revealed a similar EBV-positive lymphoid infiltrate consistent with an NK/T-cell lymphoma. EBV-positive tissue was present in gastrointestinal biopsies. Flow-cytometric analysis revealed an atypical, clonal NK-cell population, and biopsy specimens from several tissue sites tested positive for CD3, CD56, and CD30. The patient died soon after the diagnosis was made. This patient developed an EBV-driven malignancy while receiving infliximab. All patients with IBD who receive infliximab should be monitored for malignancy, especially young patients. This case underscores the need for future studies to better understand the biology of lymphoproliferative disorders.

Abstract
: affecting sphincter integrity and continence. Traditional surgical and medical approaches are not without their limitations and may result in either comorbidity, such as fecal incontinence, or incomplete healing of the fistulae. Over the last 2 decades these limitations have led to a paradigm shift toward the use of biomaterials, and more recently cell-based therapies, which have met with variable degrees of success. This review discusses the traditional and current methods of treatment, as well as emerging and possible alternative approaches that may improve fistula healing.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) patients undergo multiple radiological evaluations. AIM To estimate total and abdominal radiation exposure from diagnostic X-ray investigations in IBD patients and the associated risk factors. METHODS Patients with Crohn's disease (CD) or ulcerative colitis (UC) treated in the IBD clinic were recruited. Clinical data were extracted from patient files and radiological data were obtained from the central HMO computer data base. RESULTS A total of 199 CD and 125 UC patients were included. The mean cumulative estimated doses (CED) for CD and UC were 21.1 19.5 and 15.1 20.4 millisieverts (mSv) respectively (P < 0.001). Twenty-three patients (7.1%) had an estimated CED of > or =50 mSv. In multivariate analyses, predictors of increased CED were: surgery (OR 5.68, 95% CI: 2.73-11.8, P < 0.001), CD (OR 2.56, 95% CI: 1.29-5.07, P = 0.007), prednisone use (OR 2.0, 95% CI: 1.11-3.67, P = 0.02), first year of disease (OR 6.4, 95% CI: 1.3-32, P = 0.02) and age in the upper quartile(OR 3.26, 95% CI: 1.68-6.3, P = 0.001). CONCLUSIONS Diagnosis of CD, IBD-related surgery, prednisone use, first year of diagnosis and age on the upper quartile are independent predictors of increased exposure in IBD patients. Alternative investigations which do not require radiation exposure should be considered for patients at risk for increased radiation exposure.

Abstract
INTRODUCTION The relationship between inflammatory bowel disease (IBD) and lymphoproliferative disorders (LD) has been previously reported. AIMS To establish the local incidence of LD in an IBD unit, and to describe the clinical characteristics of observed cases. MATERIAL AND METHODS All the clinical records of patients with ulcerative colitis (UC) or Crohn's disease (CD) followed-up in a tertiary center were reviewed. In all cases, IBD had been diagnosed according to standard criteria. RESULTS Of 911 patients with IBD, we identified seven with lymphoma. Five of the patients were men, four had been diagnosed with UC and three with Crohn's disease. The mean time from IBD to lymphoma diagnosis was 4.82 years (r: 0-20). The mean age at lymphoma diagnosis was 53 years (r: 33-76). Four were colorectal lymphomas. There was only one case of Hodgkin's disease. Five patients had been treated with thiopurines, and four of these had also been treated with biological agents. Three cases were associated with Epstein-Barr (EBV) virus infection. The estimated incidence of LD in these IBD patients was 81.74/100,000/year. After a mean follow-up of 32.3 months (r: 5-57) following the last treatment for LD, all patients except one are in remission. DISCUSSION The incidence rate of LD was much higher than the expected rate for the general population (81.74 vs. 22). Chronic inflammation, immune-modifying drugs and Epstein Barr virus infection may be implicated in the pathogenesis of this disease.

Abstract
The treatment of psoriasis has undergone a revolution with the advent of biologic therapies, including infliximab, etanercept, adalimumab, efalizumab, and alefacept. Biologics are generally safe and well tolerated. However, there has been concern over the risk of lymphoma with use of these agents because of their immunosuppressive properties. This review summarizes the current evidence in regards to lymphoma risk with biologic therapy obtained from case reports and case series, observational studies, clinical trials, and meta-analyses. The majority of data for T-cell inhibitors comes from case reports and relatively small, short-term clinical trials. In addition to published case reports and case series, TNF-alpha inhibitors have also been studied extensively in large cohort studies and meta-analyses of clinical trials derived primarily from the rheumatoid arthritis population. Current data are neither sufficient to completely rule out an increased risk of lymphoma associated with biologics, nor to firmly establish a causal relationship between biologics and lymphoma. Short- to intermediate-term treatment with biologics (e.g., up to 4 years) appears to be very safe with respect to lymphoma risk, especially with TNF-alpha inhibitors in which their potential risks appear to be well defined. Continued vigilance is warranted; however, in the appropriate patient, the risk-to-benefit profile of psoriasis treatment with respect to lymphoma risk appears highly favorable.

Abstract
There is recognized increased risk for colorectal cancer in patients with inflammatory bowel disease, particularly in long-standing and extensive ulcerative colitis. There also appears to be an increased rate of intestinal cancer in Crohn’s disease, including both colon and small bowel sites. In Crohn’s disease, evidence suggests that detection of colorectal cancer may be delayed with a worse prognosis. Some risk factors for cancer in Crohn’s disease include the extent of inflammatory change within the colon and the presence of bypassed or excluded segments, including rectal “stump” cancer. In addition, the risk for other types of intestinal neoplasms may be increased in Crohn’s disease, including lymphoma and carcinoid tumors. Earlier detection of colorectal cancer based on colonoscopy screening and surveillance may be achieved but, to date, this has not translated into a positive survival benefit. Moreover, newer staining methods and evolving micro-endoscopic techniques show promise, but have not significantly altered management. Future research should focus on development of molecular or other bio-markers that might predict future dysplasia or cancer development in Crohn’s disease.

Abstract
INTRODUCTION The aim of this study was to describe the clinical experience of our center of the use of infliximab in pediatric patients with inflammatory bowel disease. MATERIAL AND METHODS We retrospectively reviewed all infliximab infusions administered in the Pediatric Gastroenterology Unit from October of 1999 to October of 2006. Fourteen patients (nine with Crohn's disease, three with ulcerative colitis, and two with indeterminate colitis) with a mean age of 9.6 years at diagnosis were treated with infliximab. Seventy-seven infusions were administered. RESULTS Efficacy was analyzed according to inflammatory bowel disease. Crohn's disease: in severe cases (PCDAI > 30), clinical remission (PCDAI < 10) was obtained in 80 % of the patients at week 10, decreasing to 60 % at week 54. Corticosteroid therapy could be reduced in 89 % of the patients and was discontinued in 55.5 %. Ulcerative colitis: clinical remission (modified Truelove-Witts index < 10) was initially obtained in 100 % of the patients but only 33 % were still in clinical remission at the end of the study. In the two corticosteroid-dependent patients, corticosteroid therapy could be reduced and even discontinued in one (50 %). Indeterminate colitis: neither of the two patients achieved clinical remission. The most frequent adverse effects observed were acute infusional reactions (42.8 % of the patients and 10.3 % of infusions), one of which was severe, and infections (28.6 % of patients), one of which (ileal abscess) required surgery. CONCLUSIONS The efficacy of infliximab seems to differ considerably in the distinct types of inflammatory bowel disease and is practically null in indeterminate colitis. Randomized controlled studies in children are required to assess the exact efficacy of infliximab in our patients.

An unusual case of Crohn's disease with unresponsive pleural exudates. Is Crohn's disease finally a systemic immunological disorder? J Crohns Colitis 2007; 1:116-21.

Abstract
Crohn's disease has been infrequently associated with various respiratory manifestations. Reports of pleural effusions in Crohn's disease are even sparser, but differential diagnosis is rich, with causes either associated with the disease or being independent. Processes directly or indirectly related to therapy, entities overlapping with Crohn's disease in pathogenesis and common causes of effusions should all be considered, under the guidance of laboratory testing and imaging. We report here an unusual case of bilateral pleural effusions unresponsive so far to medical therapy, in a patient with long-standing Crohn's disease and several features of autoimmunity. A short review of the literature is presented, the differential diagnosis is outlined and the systemic immunological profile of Crohn's disease is discussed.

Abstract
Since 1964 only nine cases of multiple myeloma occurring in the setting of inflammatory bowel disease have been reported. Although this occurrence may be a mere unfortunate coincidence, there are sound pathophysiological reasons for such an event. The possibility that chronic inflammatory conditions, immunomodulator therapy, and infliximab can predispose to multiple myeloma and lymphoma is reviewed. We discuss in detail the only reported case of multiple myeloma arising in the setting of infliximab treatment for Crohn's disease. It is highly probable that infliximab therapy had a causal role in our patient developing multiple myeloma. The pathogenesis of multiple myeloma arising in the setting of infliximab therapy may be related to decreased apoptosis of plasma cell populations. Since it is possible that a causal association exists between infliximab therapy and multiple myeloma, additional screening measures may be required in patients with Crohn's disease on infliximab.

Abstract
BACKGROUND Infliximab is used for refractory Crohn's disease but there are concerns regarding long-term safety. Recently, JC-polyomavirus (JCV) was studied after 3 cases of progressive multifocal leukoencephalopathy (PML) were found after treatment with natalizumab. The aim of this study was to investigate the short-term effect of infliximab on reactivation of several harmful latent viruses. METHODS Sixty consecutive patients scheduled for infliximab induction course were prospectively enrolled. Blood samples were taken before each infliximab infusion at 0, 2, 6, and 14 weeks. Specific polymerase chain reaction (PCR) analyses were performed to detect JCV, Epstein-Barr virus (EBV), human herpes virus-6, (HHV-6), -7, -8, and cytomegalovirus (CMV). RESULTS Indications to infliximab were luminal and fistulizing disease in 49 and 15 cases, respectively. Clinical improvement and remission were achieved in 54 (90%) and 39 (65%) of patients, respectively, at 6 weeks. No patient was JCV-positive at any timepoint. EBV serology was positive for 59/60 patients (98%); EBV-PCR tests were transiently positive (>40 copies/10(5) Peripheral blood mononuclear cells, PBMC) in 4 (7%) patients after infliximab, but in each case were negative at subsequent timepoints. All patients were negative for HHV-6, -7, and -8 at all timepoints. CMV serology was positive in 42 patients (70%), but no CMV-PCR-positive patient was observed. There was no association between concomitant treatments or clinical characteristics and viral status. CONCLUSIONS Our results support the safety of short-term infliximab treatment with respect to latent virus reactivation. The long-term effects of infliximab, particularly for the issue of lymphoproliferative disorders, warrants further studies with larger populations, but so far data are reassuring.

Abstract
PURPOSE The risk of cancer in patients with Crohn's disease is not well defined. Using meta-analytical techniques, the present study was designed to quantify the risk of intestinal, extraintestinal, and hemopoietic malignancies in such patients. METHODS A literature search identified 34 studies of 60,122 patients with Crohn's disease. The incidence and relative risk of cancer were calculated for patients with Crohn's disease and compared with the baseline population of patients without Crohn's disease. Overall pooled estimates, with 95 percent confidence intervals, were obtained, using a random-effects model. RESULTS The relative risk of small bowel, colorectal, extraintestinal cancer, and lymphoma compared with the baseline population was 28.4 (95 percent confidence interval, 14.46-55.66), 2.4 (95 percent confidence interval, 1.56-4.36), 1.27 (95 percent confidence interval, 1.1-1.47), and 1.42 (95 percent confidence interval, 1.16-1.73), respectively. On subgroup analysis, patients with Crohn's disease had an increased risk of colon cancer (relative risk, 2.59; 95 percent confidence interval, 1.54-4.36) but not of rectal cancer (relative risk, 1.46; 95 percent confidence interval, 0.8-2.55). There was significant association between the anatomic location of the diseased bowel and the risk of cancer in that segment. The risk of small bowel cancer and colorectal cancer was found to be higher in North America and the United Kingdom than in Scandinavian countries with no evidence of temporal changes in the cancer incidence. CONCLUSIONS The present meta-analysis demonstrated an increased risk of small bowel, colon, extraintestinal cancers, and lymphoma in patients with Crohn's disease. Patients with extensive colonic disease that has been present from a young age should be candidates for endoscopic surveillance; however, further data are required to evaluate the risk of neoplasia over time.

Abstract
The recent introduction of infliximab, a chimeric monoclonal antibody against tumor necrosis factor-alpha, has greatly modified the treatment of Crohn's disease (CD). Data from the literature show encouraging results after intravenous infusion both for closure of intestinal or perianal fistulas and for induction and maintenance of remission in patients with moderate to severe intestinal disease unresponsive to other treatments. However, some contraindications such as fibrostenosing CD and sepsis have been identified. In addition, the data on long-term outcomes and safety is still limited. Our initial experience showed that in selected cases local injection of infliximab is effective in the treatment of complex perianal disease offering the possibility of using such treatment even in small bowel obstructing disease with minimal systemic effects. This paper analyzes the state of the use of both intravenous and local injection of infliximab in patients with CD.

Abstract
Infliximab is used in the treatment of various diseases, such as rheumatoid arthritis (RA), psoriasis, psoriatic arthritis (PA), Crohn's disease (CD) and ankylosing spondylitis (AS). In most countries, infliximab is given in hospitals or infusion centers, which are experienced in the management of infusion reactions. Because of this side effect, general practitioners (GPs) might refuse to administer infliximab in their offices. The aim of this study was to investigate the safety of infliximab administration in GPs' offices. Health system in the provincial state of Upper Austria (Austria) provides reimbursement of biological treatment only in outpatient care. Infliximab is due to cost effectiveness usually administered by GPs after a specific training and initialisation of treatment by specialists in the hospital. We sent out a form to 42 cooperating GPs, containing 20 questions concerning the administration of infliximab. Thirty-four forms were returned and evaluated. Altogether, 69 patients (2 patients per doctor mean) were treated with infliximab (1-42 months; 21 months mean). The overall observation period was 697 patients-months. During this period, 487 infusions (14.5 infusions per doctor mean) were administered. From five doctors, seven adverse events (AE) in six patients were reported. In all seven cases, infusion was discontinued; two had allergic reactions and five had nausea or cardiac symptoms, not definitely of allergic origin. Severe adverse events (SAE), defined as shock, emergency treatment or hospitalisation during or after infliximab administration were reported by two doctors. In contrast, SAE during the infusion of other drugs (e.g. analgetics, vitamins) were previously seen by 16 doctors, showing the overall possibility of infusion reactions with commonly prescribed drugs. Almost all (31/34) confirmed the overall safety of infliximab administration in GP's patient care. The administration of infliximab by specially trained general practitioners with background guidance through rheumatologist or gastroenterologist centers seems to be a safe and acceptable way to provide long-term treatment with infliximab to patients in need of biological treatment.

Abstract
The proven involvement of cytokines in the pathophysiology of IBD has led to the development of powerful, selective, anticytokine drugs--so-called biologics--as a therapy for IBD. Although the efficacy of infliximab, a chimeric monoclonal IgG1 antibody directed against tumor necrosis factor, is proven and the use of biologic agents is growing worldwide, there is concern about their long-term safety, which includes the risk of developing cancer. An increased risk of malignancies, particularly lymphoma, has been reported in some studies of infliximab-treated patients with IBD; however, the increased risk could be caused by the underlying chronic disease, severity of the disease, concomitant medications (e.g. conventional immunomodulators), infliximab itself, or all of these variables. At present, the data do not provide clear evidence for a causal association between infliximab and the increased cancer risk. In appropriately selected patients with severe, refractory Crohn's disease, the benefits of biologic therapy seem to outweigh the cancer risk. Multicenter, case-control studies in large populations, with a long-term follow-up are needed to define the outcome of patients with IBD treated with biologic therapies.

Abstract
Infliximab has been available in the United States and Europe for more than 6 years, and its use has revolutionized the care of patients who have CD. It is used effectively for both the induction and maintenance of remission in patients who have CD and is efficacious in patients who have steroid-dependent/refractory CD and those who have fistulizing CD. Clinical trials and practice have shown infliximab to be safe, effective, and generally well tolerated. The ACCENT I and ACCENT II trials defined the best dosing and schedule regimens for its administration. With up to 30% of patients not responding to infliximab therapy, much attention has been devoted to identifying risk factors that could allow optimization of response rates. Parsi and colleagues and Arnott and colleagues demonstrated that nonsmoking and the concurrent use of immunomodulators are predictors of response to infliximab. Research has also focused on identifying biologic and immunologic markers that may correlate with response to infliximab. To date, N0D2/CARD15, anti-Saccharomyces cerevisiae antibody (ASCA), and antineutrophil cytoplasmic antibody (ANCA) have not been shown to be predictive of outcome with infliximab treatment for CD. Gene polymorphisms also are being studies with the hope that knowing the patient's genotype may help predict the course or severity of the disease, including the presence of extraintestinal manifestations, response to treatments, and susceptibility to toxicities. No single variable, however, has been consistently demonstrated to be a predictor of response to infliximab. The formation of ATIs in a small number of patients creates a clinical dilemma. ATIs have been associated with an attenuated response or loss of response to the medication over time and the development of both acute and delayed infusion reactions that occasionally are severe enough to lead to discontinuation of the medication. In such patients physicians are often left to ponder what therapy to try next. Adalimumab, a fully human monoclonal antibody used for treating rheumatologic conditions, has been investigated as an alternate treatment for patients who have CD who, after initially responding to infliximab, experience intolerance or loss of efficacy. Two studies have examined the use of adalimumab in patients who have active CD who had lost response to or developed intolerance to infliximab. In both these studies adalimumab was well tolerated and seemed to be a clinically beneficial option for such patients. Confirmation of these findings with ongoing randomized, double-blind, placebo-controlled trials is needed, however. The limits of conventional treatment for CD can be seen as a positive evolutionary force favoring the development and use of advanced therapies. The acceptance of antimetabolites began with data published a quarter-century ago and became robust in the past 5 to 10 years. Biologic therapy has become the standard of care at a far faster rate. The success seen with infliximab has broadened the acceptance of biologic therapy among professional peers, patients, and pharmaceutical developers. The lessons learned in the years since infliximab's arrival show the importance of long-term data in revealing important toxicities and best practices for maintenance. Tempered by this experience, the short cycle from concept to drug production possible with biologic therapies should bring even more advanced treatments to patients quickly while investigators work to find a cure.

Abstract
OBJECTIVE To assess the effectiveness of infliximab (Remicade) in the treatment of patients with sarcoidosis who either do not respond to corticosteroids and other conventional drugs or develop unacceptable side effects to these drugs. DESIGN A clinical, non-randomized, off-label study. SETTING Sarcoidosis clinic at a university teaching hospital. PATIENTS Twelve biopsy-proven sarcoidosis patients, nine women and three men ranging from 45 to 70 years of age with chronic multisystem sarcoidosis refractory to corticosteroids or alternative treatment. INTERVENTION Infliximab was infused at a dedicated ambulatory infusion center. The initial dose was 3mg/kg body weight and subsequent doses were given at weeks 2, 4, 6, 10, and 14. All patients received at least six infusions. RESULTS All 12 patients improved significantly. One patient had a mild allergic drug reaction that responded to antihistamine. One patient, after 3 months of stopping infliximab treatment, died of a ruptured blood vessel in the abdomen. At autopsy a plasma cell dyscrasia was found. CONCLUSION Infliximab is safe and effective in treating those patients with multisystem sarcoidosis who are either refractory or develop side effects to a standard regimen of corticosteroids and immunosuppressive agents.

Abstract
There has been a multitude of case reports, case series, hospital-based, and population-based studies that link CD to various types of cancers. When each of these studies is scrutinized, however, there is only enough evidence to support a link between colorectal adenocarcinoma, SBA, and squamous and adenocarcinomas that are associated with perianal fistulizing disease. All of the studies of large bowel adenocarcinoma or SBA follow patients in an era during which there were far fewer effective medicines to treat CD and surgery was more commonplace. The only surveillance study of patients who had extensive, long-duration Crohn's colitis showed a 22% risk for developing neoplasia (low-grade, high-grade, or cancer) after four surveillance examinations. Overall results from this study and the multitude of the other studies show that the risk for cancer in Crohn's colitis is equal to that in UC given equal extent and duration of disease. Patients who have Crohn's colitis that affects at least one third of the colon and with at least 8 years of disease should undergo screening and surveillance, just as in UC. Although the absolute risk for SBA in CD is low (2.2% at 25 years in one study), we should not rule out screening and surveying for this complication that is associated with significant morbidity and mortality in patients who have long-standing, extensive, small bowel disease. The risk for lymphoma and leukemia in CD is low, but immunomodulators and biologics may increase this risk. The evidence that links carcinoid tumors to CD is weak, and population-based studies need to be done. The study of cancers that are associated with CD is an evolving field that surely will change given that immunomodulators and biologics are being used with greater frequency.

Abstract
Infliximab, monoclonal antibody against tumor necrosis factor alpha, is an effective agent in the therapy of Crohn's disease. Although therapy with infliximab is generally well tolerated, there is an obvious concern about the effect of this treatment on the incidence of cancer. We report a case of mucinous anorectal adenocarcinoma observed in a 39-year-old patient with long-standing Crohn's disease after therapy with two courses of infliximab. The carcinoma was discovered fortuitously after abdominoperineal resection. Despite clear margins, the tumor recurred in a few months and progressed during combination chemotherapy. Although there is currently no definitive proof of a causal link between infliximab therapy and cancer, the present observation and other reports in the literature should lead to a careful evaluation of the possibility of increased cancer risk in patients treated with this new agent.

Abstract
Pain is one of the classical signs of the inflammatory process in which sensitization of the nociceptors is the common denominator. This sensitization causes hyperalgesia or allodynia in humans, phenomena that involve pain perception (emotional component+nociceptive sensation). As this review focuses mainly on animal models, which don't allow discrimination of the emotional component, the terms nociception and hypernociception are used to describe overt behavior induced by mechanical stimulation and increase of nociceptor sensitivity, respectively. Pro- and anti-inflammatory cytokines and chemokines are endogenous small protein mediators released by local or migrating cells whose balance modulates the intensity of inflammatory response. The inflammatory stimuli or tissue injuries stimulate the release of characteristic cytokine cascades, which ultimately trigger the release of final mediators responsible for inflammatory pain. These final mediators, such as prostanoids or sympathetic amines, act directly on the nociceptors to cause hypernociception, which results from the lowering of threshold due to modulation of specific voltage-dependent sodium channels. Furthermore, a direct effect of cytokines on nociceptors is also described. On the other hand, there are also anti-inflammatory cytokines, such as interleukin (IL)-10, IL-4 and IL-13, and IL-1 receptor antagonists (IL-1ra), which inhibit the production of hypernociceptive cytokines and/or the final hypernociceptive mediators, preventing the installation of or the increase in the hypernociception. This review highlights the importance of the direct and indirect actions of cytokines and chemokines in inflammatory and neuropathic hypernociception, emphasizing the evidence suggesting these molecules are potential targets to develop novel drugs and therapies for the treatment of pain.

Abstract
OBJECTIVE Chronic inflammatory conditions such as rheumatoid arthritis (RA) have been associated with malignant lymphomas. This study was undertaken to investigate which patients are at highest risk, and whether antirheumatic treatment is hazardous or protective. METHODS We performed a matched case-control study of 378 consecutive Swedish RA patients in whom malignant lymphoma occurred between 1964 and 1995 (from a population-based RA cohort of 74,651 RA patients), and 378 controls. Information on disease characteristics and treatment from onset of RA until lymphoma diagnosis was abstracted from medical records. Lymphoma specimens were reclassified and tested for Epstein-Barr virus (EBV). Relative risks (odds ratios [ORs]) for lymphomas (by subtype) associated with deciles of cumulative disease activity were assessed, as were ORs associated with drug treatments. RESULTS The relative risks of lymphoma were only modestly elevated up to the seventh decile of cumulative disease activity. Thereafter, the relative risk increased dramatically (OR ninth decile 9.4 [95% confidence interval 3.1-28.0], OR tenth decile 61.6 [95% confidence interval 21.0-181.0]). Most lymphomas (48%) were of the diffuse large B cell type, but other lymphoma subtypes also displayed an association with cumulative disease activity. Standard nonbiologic treatments did not increase lymphoma risk. EBV was present in 12% of lymphomas. CONCLUSION Risk of lymphoma is substantially increased in a subset of patients with RA, those with very severe disease. High inflammatory activity, rather than its treatment, is a major risk determinant.

Abstract
We present the case of a 79-year-old woman who had received a diagnosis of Crohn's disease 3 years previously and who developed a mucosa-associated lymphoid tissue (MALT) lymphoma of the right colon while undergoing treatment with mesalazine. The patient had not received immunosuppressive drugs or infliximab. The possible association between Crohn's disease and the development of intestinal lymphomas is analyzed. The incidence, pathogenic mechanisms, diagnostic strategy, treatment and prognosis of these neoplasms are described, mainly with reference to MALT lymphomas of the colon.

Abstract
Immunosuppressive agents have become an established part of the therapeutic armamentarium for inflammatory bowel disease (IBD). However, when used in transplant recipients or for other indications, agents that suppress or modulate the immune system (immunomodulators) have been associated with an increased risk of lymphoma. Fortunately, in part because of the lower doses used in IBD patients, the risk of lymphoma in IBD patients appears to be significantly less than that associated with renal and hepatic transplant-related immunosuppression. Whether the risk of azathioprine or 6-mercaptopurine associated lymphoma in IBD is real or relates to the underlying disease remains unclear. The results of several recent large well designed population-based studies suggest that the lymphoma risk associated with azathioprine and 6-mercaptopurine therapy is likely to be of minimal clinical significance compared to the established and more frequent risks of myelosuppression and infection, and is far outweighed by the clinical benefit of immunomodulator therapy in IBD. While the issue of lymphoma risk is likely to become more relevant with the growing number of biologic and immunomodulators being tested in clinical trials for IBD, early post-marketing surveillance data on infliximab suggests that the lymphoma risk may not be any greater than that associated with azathioprine and 6-mercaptopurine.

Abstract
OBJECTIVE Geranylgeranylacetone (GGA) has recently been reported to induce heat shock protein (HSP) 70, which has a protective function against inflammation. We investigated the therapeutic effects of oral administration of GGA on dextran sulfate sodium (DSS)-induced colitis in mice. MATERIALS AND METHODS BALB/c mice were given 3% DSS solution orally for 7 days to induce colitis. The disease activity of colitis was assessed clinically every day, and histology in the colon was evaluated at 7 days post-DSS. The levels of myeloperoxidase (MPO) activity, tumor necrosis factor (TNF)-alpha and interferon (IFN)-gamma in the colon tissues were also examined. In addition, expression of HSPs 25, 40, 70 and 90 in the colon tissue was determined by Western blot analysis. Mice were orally administered GGA (50-500 mg/kg) when treatment of DSS started. RESULTS It was found that GGA significantly reduced the clinical severity of colitis and suppressed the levels of MPO activity, TNF-alpha and IFN-gamma induced by DSS in the colon. On the other hand, GGA enhanced the expression of HSP70 in the colon of mice given DSS. CONCLUSIONS Taken together, these results suggest that GGA is a new anti-inflammatory drug that could be useful in the treatment of colitis such as inflammatory bowel disease.

Abstract
Conventional therapy for inflammatory bowel diseases rely on corticosteroids and 5-aminosalicylates combined with immunosuppressive agents for maintenance. These drugs are not always effective and may inflict serious side effects. Other therapies are therefore awaited. Infliximab, a monoclonal antibody against the pro-inflammatory cytokine TNF-alpha has been successfully applied as a treatment for Crohn's disease. The mechanism of action of this drug extends beyond the level of TNF-alpha scavenging and includes induction of apoptosis of effector cells. Numerous anti-TNF antibodies have been developed and are currently evaluated in clinical trials. Other targets for monoclonal antibodies include integrins and cytokines involved in T-cell differentiation and activation. Likewise recombinant proteins that moderate TNF bioactivity and lymphocyte function have been developed. The therapeutic effect of recombinant interleukin-10 seems to be dependent on local delivery of the protein. Antisense therapy targeting lymphocyte migration has also been tested in IBD. Finally, the conventional drug thalidomide and possibly MAP-kinase inhibitors may become novel treatment entities for IBD.
