The Complete Success in Refractory Mooren's Ulcer Treated with Infliximab

PURPOSE

To describe the management and outcome of two extremely rare and painful cases of Mooren's ulcer, an idiopathic peripheral autoimmune-associated ulcerative corneal disease.

METHODS

Case report with literature review on the management of ocular inflammation in Mooren's ulcer.

RESULTS

A 47-year-old female and a 76-year-old female presented with progressive bilateral Mooren's ulcer that were refractory to conventional immunosuppressive therapy. Following treatment with infliximab, an anti-tumor necrosis factor alpha, a significant improvement in disease progression was observed, with no corneal thinning or perforation at follow-ups.

CONCLUSION

This case report highlights how infliximab can be effective in cases with Mooren's ulcer refractory to conventional therapies.

Clinical Course of Hepatitis B Viral Infection in Patients Undergoing Anti-Tumor Necrosis Factor α Therapy for Inflammatory Bowel Disease

Background/Aims

Little is known about the clinical course of hepatitis B virus (HBV)-infected patients undergoing anti-tumor necrosis factor α (TNF-α) therapy for inflammatory bowel disease (IBD). We aimed to investigate the clinical course of HBV infection and IBD and to analyze liver dysfunction risks in patients undergoing anti-TNF-α therapy.

Methods

This retrospective multinational study involved multiple centers in Korea, China, Taiwan, and Japan. We enrolled IBD patients with chronic or resolved HBV infection, who received anti-TNF-α therapy. The patients’ medical records were reviewed, and data were collected using a web-based case report form.

Results

Overall, 191 patients (77 ulcerative colitis and 114 Crohn’s disease) were included, 28.3% of whom received prophylactic antivirals. During a median follow-up duration of 32.4 months, 7.3% of patients experienced liver dysfunction due to HBV reactivation. Among patients with chronic HBV infection, the proportion experiencing liver dysfunction was significantly higher in the non-prophylaxis group (26% vs 8%, p=0.02). Liver dysfunction occurred in one patient with resolved HBV infection. Antiviral prophylaxis was independently associated with an 84% reduction in liver dysfunction risk in patients with chronic HBV infection (odds ratio, 0.16; 95% confidence interval, 0.04 to 0.66; p=0.01). The clinical course of IBD was not associated with liver dysfunction or the administration of antiviral prophylaxis.

Conclusions

Liver dysfunction due to HBV reactivation can occur in HBV-infected IBD patients treated with anti-TNF-α agents. Careful monitoring is needed in these patients, and antivirals should be administered, especially to those with chronic HBV infection.

Hemorrhagic pericardial effusion following treatment with infliximab: A case report and literature review

BACKGROUND

Infliximab (IFX) is an anti-tumor necrosis factor alpha (TNF-α) agent that is widely used for the management of a variety of autoimmune and inflammatory diseases, including Crohn's disease (CD). As a result of its increasing administration, new complications have emerged. Hemorrhagic pericardial effusion, secondary to IFX therapy, is a rare but life-threatening complication.

CASE SUMMARY

A 27-year-old man was diagnosed with CD (Montreal A2L3B1) 6 years prior. After failing to respond to mesalazine and methylprednisolone, he took the first dose of IFX 300 mg based on his weight (60 kg, dose 5 mg/kg) on December 3, 2018. He responded well to this therapy. However, on January 21, 2019, 1 wk after the third injection, he suddenly developed dyspnea, fever, and worsening weakness and was admitted to our hospital. On admission, computed tomography scan of the chest revealed a large pericardial effusion and a small right-side pleural effusion. An echocardiogram showed a large pericardial effusion and normal left ventricular function. Then successful ultrasound-guided pericardiocentesis was performed and 600 mL hemorrhagic fluid was drained. There was no evidence of infection and the concentrations of TNF-α, IFX, and anti-IFX antibody were 7.09 pg/mL (reference range < 8.1 pg/mL), < 0.4 μg/mL (> 1.0 μg/mL), and 373 ng/mL (< 30 ng/mL), respectively. As the IFX instruction manual for injection does mention pericardial effusion as a rare adverse reaction (≥ 1/10000, < 1/1000), so we discontinued the IFX. Monitoring of the patient’s echocardiogram for 2 mo without IFX therapy showed no recurrence of hemorrhagic pericardial effusion. Follow-up visits and examinations every 3 to 6 mo until April 2021 showed no recurrence of CD or pericardial effusion.

CONCLUSION

This is a case of hemorrhagic pericardial effusion following treatment with IFX. It is a rare but life-threatening complication of IFX. Early recognition helps prevent the occurrence of hemorrhagic pericardial effusion and minimize the impact on the natural evolution of the disease.

Sarcoidosis presenting with glazy mucoid sputum and dyspnea: a case report

BACKGROUND

Patients with pulmonary sarcoidosis commonly present with a dry cough; a productive cough suggests a complicating airway infection or an alternative diagnosis such as tuberculosis or bronchiectasis.

CASE PRESENTATION

A 36-year-old European (Frisian) woman recently diagnosed with pulmonary sarcoidosis presented with debilitating exertional dyspnea and cough productive of glazy mucoid sputum. Several different attempts including video-assisted thoracoscopic biopsies failed to reach a second or alternative diagnosis including an infectious, autoimmune or collagen-vascular condition. She responded to steroids but with poor tolerance to this treatment, which could not be tapered. After she was started on anti-tumor necrosis factor alpha (TNF-α) therapy with infliximab, 200 mg at three-monthly intervals, she has been fine for well over a decade.

CONCLUSIONS

In this patient with sarcoidosis who had a productive cough accompanied by fever, an extensive workup and prolonged follow-up, an alternative or second diagnosis could be ruled out; we therefore conclude that this highly unusual presentation is part of the clinical spectrum of sarcoidosis.

Obesity and Remission Rates in Japanese Patients With Rheumatoid Arthritis Requiring Anti-Tumor Necrosis Factor Alpha Therapy

Objectives

This study aims to determine if obesity is a risk factor for a poor response to anti-tumor necrosis factor alpha (anti-TNFα) therapy in Japanese patients with rheumatoid arthritis (RA) using the appropriate body mass index (BMI) cut-off points for Asian populations.

Patients and methods

This retrospective cohort study evaluated 382 outpatients with RA (98 males, 284 females; mean age 54.2 years; range, 18 to 84 years) who had received anti-TNFα therapy between May 2009 and July 2017. Patients were classified according to BMI at baseline as follows: <18.5 kg/m² (underweight), 18.5-23.0 kg/m² (normal weight), 23.0-27.5 kg/m² (overweight), and ≥27.5 kg/m² (obese). The response variable was defined as Simplified Disease Activity Index (SDAI) remission after 12 months. We estimated odds ratios (ORs) and their 95% confidence intervals (CIs) for poor response to the therapy.

Results

After 87 patients were excluded, 183 (62.0%) of 295 had reached remission at the 12-month follow-up. Compared with normal-weight patients, the multivariate OR for poor response of obese patients was 2.2 (95% CI: 0.5-9.4). Adjusting for the baseline SDAI score, the corresponding OR was 1.8 (0.4-7.6).

Conclusion

We found no statistically significant association between obesity and poor response to anti-TNFα therapy in Japanese patients with RA. Because this may partly be due to the limited statistical power of our study, further research is warranted to examine the possible effect modification across countries.

Analysis of Safety, Medical Resource Utilization, and Treatment Costs by Drug Class for Management of Inflammatory Bowel Disease in the United States Based on Insurance Claims Data

INTRODUCTION

Conventional pharmaceutical interventions for inflammatory bowel disease (IBD) provide limited disease/symptom control and are associated with an increased risk of adverse events (AEs). These limitations increase patient morbidity, medical resource utilization (MRU), and costs.

METHODS

The IQVIA™ Real-World Data Adjudicated Claims-US database was leveraged to identify adult patients (> 18 years) with Crohn's disease (Crohn's) or ulcerative colitis (UC), who were new and chronic users (≥ 60 days) of oral corticosteroids (OCS), immunosuppressants (IS), anti-tumor necrosis factor agents (anti-TNF) or combinations thereof. Using aminosalicylate-treated patients as a reference, we compared AE incidence, MRU, and medical costs across drug classes.

RESULTS

The analysis included 30,676 patients (Crohn's: n = 14,528; UC: n  = 16,148). OCS monotherapy was the strongest predictor of any AE occurring [Crohn's: hazard ratio 1.62 (1.51-1.73); UC: hazard ratio 1.57 (1.49-1.66)]. A similar pattern was observed for severe infection and bone-related conditions. Patients with UC or Crohn's receiving OCS or IS plus OCS were more likely to have emergency department visits, IBD-related hospitalizations/visits/procedures, and gastrointestinal surgery than were patients receiving other therapies. Annualized total medical costs (pharmacy plus hospital service costs) were greatest for anti-TNF plus IS or anti-TNF therapy in both Crohn's and UC. Annualized medical service costs (excluding IBD drug costs) were highest for patients initiating OCS-containing therapies [Crohn's: OCS, $27,041 (24,882-29,200) and OCS plus IS, $23,332 (19,889-26,775); UC: OCS, $19,659 (17,977-21,340)].

CONCLUSION

Although biologic therapies have higher pharmacy costs, treatment decisions should consider the increased AE risks and long-term MRU costs associated with chronic use of OCS-containing therapies.

Effectiveness of vedolizumab treatment in two different anti-tumor necrosis factor alpha refractory pouchitis: A case report

BACKGROUND

Refractory pouchitis is a common cause of pouch failure, which may require surgical excision of the pouch or permanent diversion. We aimed to show the effect of vedolizumab on treatment of the patient with refractory pouchitis.

CASE SUMMARY

A 32-year-old male with pancolonic ulcerative colitis since the age of 25 with primary failure of infliximab and mesalamine and intolerance of azathioprine, underwent a total proctocolectomy with ileal pouch-anal anastomosis in 2012. He developed chronic diarrhea in 2014, which was watery, 30 per day and accompanied with blood and mucus affecting his quality of life.

CONCLUSION

Vedolizumab is safe and effective in the management of anti-tumor necrosis factor alpha refractory pouchitis.

Changes in the rate of and trends in colectomy for ulcerative colitis during the era of biologics and calcineurin inhibitors based on a Japanese nationwide cohort study

PURPOSE

We evaluated the recent incidence of surgery and the changing surgery trends for ulcerative colitis (UC) in Japan due to the increasing use of anti-tumor necrosis factor (TNF) agents.

METHODS

A questionnaire survey was performed to assess the number of surgeries, surgical indications, surgical timing, and immunosuppressive treatments before surgery between 2007 and 2017.

RESULTS

A total of 3801 surgical cases were reported over 11 years. The prevalence of UC surgery decreased over the period studied. The rate of prednisolone (PSL) use did not change. The prevalence of both calcineurin inhibitors (CNIs) and anti-TNF agents increased during the period studied (p < 0.01). The prevalence of urgent/emergent surgery did not change. The most distinctive change in surgical indications was the increase in cancer/dysplasia (CAC), the prevalence of which increased from 20.2% in 2007 to 34.8%.

CONCLUSION

The prevalence of UC surgery seems to be decreasing according to the increasing rate of anti-TNF agent and CNI administration. However, the indication of CAC significantly increased. Further research should evaluate whether or not long-term remission maintained with several agents can lead to increasing CAC.

Anti-Tumor Necrosis Factor Therapy in Intestinal Behçet's Disease

Intestinal Behçet’s disease is a rare, immune-mediated chronic intestinal inflammatory disease; therefore, clinical trials to optimize the management and treatment of patients are scarce. Moreover, intestinal Behçet’s disease is difficult to treat and often requires surgery because of the failure of conventional medical treatment. Administration of anti-tumor necrosis factor–α, a potential therapeutic strategy, is currently under active clinical investigation, and evidence of its effectiveness for both intestinal Behçet’s disease and inflammatory bowel diseases has been accumulating. Here, we review updated data on current experiences and outcomes after the administration of anti-tumor necrosis factor–α for the treatment of intestinal Behçet’s disease. In addition to infliximab and adalimumab, which are the most commonly used agents, we describe agents such as golimumab, etanercept, and certolizumab pegol, which have recently been shown to be effective in refractory intestinal Behçet’s disease. This review also discusses safety issues associated with anti-tumor necrosis factor–α, including vulnerability to infections and malignancy.

Two-year delay in ulcerative colitis diagnosis is associated with anti-tumor necrosis factor alpha use

BACKGROUND

Ulcerative colitis (UC) is an uncommon inflammatory bowel disease (IBD). However, its incidence has recently increased in South Korea. Moreover, UC diagnoses are frequently delayed, and the relationship between diagnostic delay and UC prognosis has not been extensively studied in South Korean patients.

AIM

To identify meaningful diagnostic delay affecting UC prognosis and to evaluate risk factors associated with diagnostic delay in South Korean patients.

METHODS

Medical records of 718 patients with UC who visited the outpatient clinic of six university hospitals in South Korea were reviewed; 167 cases were excluded because the first symptom date was unknown. We evaluated the relationship between the prognosis and a diagnostic delay of 3, 6, 12, 18, and 24 mo by comparing the prognostic factors [anti-tumor necrosis factor (TNF)-α use, admission history due to acute flare-ups, frequent admission due to flare-ups, surgery associated with UC, and the clinical remission state at the latest follow-up] at each diagnostic interval.

RESULTS

The mean diagnostic interval was 223.3 ± 483.2 d (median, 69 d; 75^th percentile, 195 d). Among the prognostic factors, anti-TNFα use was significantly increased after a diagnostic delay of 24 mo. Clinical risk factors predictive of a 24-mo diagnostic delay were age < 60 years at diagnosis [odd ratio (OR) = 14.778, 95% confidence interval (CI): 1.731-126.121], smoking history (OR = 2.688, 95%CI: 1.239-5.747, P = 0.012), and misdiagnosis of hemorrhoids (OR = 11.066, 95%CI: 3.596-34.053). Anti-TNFα use was associated with extensive UC at diagnosis (OR = 3.768, 95%CI: 1.860-7.632) and 24-mo diagnostic delay (OR = 2.599, 95%CI: 1.006-4.916).

CONCLUSION

A diagnostic delay > 24 mo was associated with increased anti-TNFα use. Age < 60 years at diagnosis, smoking history, and misdiagnosis of hemorrhoids were risk factors for delayed diagnosis.

Influence of anti-tumor necrosis factor-alpha therapy to pregnant inflammatory bowel disease women and their children's immunity

Background/Aims

The onset of inflammatory bowel disease (IBD) usually occurs at young age, and therefore, women IBD patients experience pregnancy during their disease progression. Recently, the use of anti-tumor necrosis factor-α (anti-TNF-α) has been rapidly increasing. The aim of this study was to evaluate pregnancy related outcomes in women with IBD who were treated with anti-TNF-α during pregnancy and immunity of their children.

Methods

Korean women with IBD who had been treated with anti-TNF-α during pregnancy had been enrolled. Medical records were reviewed and a survey was performed for each patient. For the patients who agreed on additional examination for their children, children’s growth, medical history and antibody to hepatitis B surface antigen (anti-HBs) titer were checked.

Results

All 18 patients had been diagnosed with Crohn’s disease. There was not any case of preterm delivery, low birth-weight infant, congenital anomaly, nor stillbirth. All 12 children had followed the regular vaccination schedule for hepatitis B and 4 of them showed negative results for anti-HBs. After the 1 booster vaccination, all children demonstrated seroconversion. Regarding live vaccines, 4 children had bacillus Calmette-Guerin and 4 had rotavirus vaccine before 6 months, without any specific side effects.

Conclusions

This was the first study of immunity of the children born from IBD women who had been treated with anti-TNF-α medication during their pregnancy. IBD women had comparable pregnancy outcomes with the general women population, suggesting that the disease activity rather than the administered medication would be more important in healthy pregnancy. Considering the history of vaccination and anti-HBs titers, immunity seems to be intact in the children.

Assessment of 3-month changes in bone microstructure under anti-TNFα therapy in patients with rheumatoid arthritis using high-resolution peripheral quantitative computed tomography (HR-pQCT)

Background

Although one study showed minimal progression of erosions in patients with rheumatoid arthritis (RA) one year after TNFα inhibition therapy, no studies have investigated very early bone changes after initiation of anti-TNFα treatment. We investigated the effects of 3-month anti-TNFα treatment on bone erosion progression and bone microarchitecture in RA patients using high-resolution peripheral quantitative computed tomography (HR-pQCT).

Methods

Patients with RA (n = 27) (17 in the anti-TNFα and 10 in the MTX-only group) underwent assessment of disease activity score in 28 joints (DAS-28), radiographs, 3-T magnetic resonance imaging (MRI) and HR-pQCT of metacarpophalangeal and wrist joints at baseline and 3 months. HR-pQCT-derived erosion volume, joint volume/width and bone microarchitecture were computed and joint destruction was assessed using Sharp and RAMRIS scorings on radiographs and MRI, respectively.

Results

Overall, 73 erosions were identified by HR-pQCT at baseline. Over 3 months, the anti-TNFα group had decreased mean erosion volume; increased erosion volume was observed in one clinical non-responder. The MTX-only group in contrast, trended toward increasing erosion volume despite low disease activity. In the anti-TNFα group, joint-space width and volume of MCP joints decreased significantly and was positively correlated with erosion volume changes (R² = 0.311, p = 0.013; R² = 0.527, p = 0.003, respectively). In addition, erosion volume changes were significantly negatively correlated with changes in trabecular bone mineral density (R² = 0.353, p = 0.020) in this group. We observed significant correlation between percentage change in erosion volume and change in DAS-28 erythrocyte sedimentation rate and C-reactive protein CRP scores (R² = 0.558, p < 0.001; R² = 0.745, p < 0.001, respectively) in all patients.

Conclusions

Using HR-pQCT, our data suggest that anti-TNFα treatment prevents erosion progression and deterioration of bone microarchitecture within the first 3 months of treatment, one patient not responding to treatment, had significant progression of bone erosions within this short time period. Patients with low disease activity scores (<3.2) can have continuous HR-pQCT-detectable progression of erosive disease with MTX treatment only. HR-pQCT can be a sensitive, powerful tool to quantify bone changes and monitor RA treatment short term (such as 3 months).

Infliximab exerts a dose-dependent effect on retinal safety in the albino rabbit

PURPOSE

To assess the retinal toxicity of an intravitreal injection of infliximab, a monoclonal antibody to tumor necrosis factor α, in a rabbit model.

MATERIALS AND METHODS

Two groups of adult albino rabbits (n = 5) received intravitreal injections of infliximab (0.1 ml) in the study eye and balanced salt solution (BSS, 0.1 ml) in the control eye at baseline. Group 1 was administered with 1.5 mg/0.1 ml, and group 2 was injected with 7.5 mg/0.1 ml of infliximab solution. Electroretinography (ERG) was performed at baseline and at 1, 7, 30, and 45 days after the injection. Visual evoked potentials (VEPs) were recorded at 7 and 45 days after the injection. After the last electrophysiological assessment, the rabbits were euthanized and retinal histopathology and immunhistochemistry for glial fibrillary acidic protein (GFAP) were performed.

RESULTS

ERG responses demonstrated no significant deficit in retinal function in eyes injected with infliximab. Mean dark-adapted a-wave and b-wave maximal amplitude and semi-saturation constant values at baseline and throughout the 45 days of follow-up after the injection indicated no remarkable difference in outer retinal function between the control and experimental eyes. VEP responses were similar at each time point (7 and 45 days). No difference was seen in retinal histopathology and immunocytochemistry sections in eyes receiving the 1.5 mg/0.1 ml dose compared to the control eyes. However, increased GFAP labeling in retinal Müller cells was detected in rabbit eyes treated with the 7.5 mg/0.1 ml dose.

CONCLUSIONS

Intravitreal injection of 1.5 mg/0.1 ml infliximab dose has no toxic effect on the integrity (functional or structural) of the retina in rabbits. A higher dose of 7.5 mg/0.1 ml may be slightly toxic as suggested by positive Müller cell GFAP expression. Additional studies of retinal toxicity at higher doses and after multiple injections are needed to establish the retinal safety of intravitreal infliximab therapy in humans.

Cryptosporidial infection in children with inflammatory bowel disease

BACKGROUND AND AIMS

Cryptosporidiosis is usually a self-limiting illness in healthy patients. However, it can cause severe life threatening complications in immunocompromised patients. The effect of cryptosporidial infection on inflammatory bowel disease (IBD) has not been well studied and available literature is largely restricted to adult case reports. The purpose of this study is to describe the clinical characteristics of cryptosporidial infection in children with IBD.

METHODS

Stool studies from children with IBD presenting with presumed relapse during the period 2005-2011 were reviewed retrospectively. Cryptosporidial infection was diagnosed by stool enzyme immunoassay. An age matched control group of IBD patients without cryptosporidial infection was used for comparison.

RESULTS

Medical records of 170 IBD patients were reviewed and a total of 149 presumed relapses were identified. Cryptosporidial infection was found in seven of the 39 patients with positive stool studies (four ulcerative colitis/three Crohn's disease) presenting with relapse. The median age was 13 years (range: 3-17) and five patients were female. The median duration of the IBD was 18 months (range 2-48 months). All but one patient had stable disease prior to acquiring infection. Five patients required hospitalization due to significant dehydration. Three of the five patients treated with nitazoxanide had significant clinical improvement in 3 days. All patients had complete resolution of symptoms by three weeks and no infection related complications were noted. In comparison to patients with cryptosporidial infection, the control group required an increased need for escalation of therapy (71% vs. 0.0%, p=001) and higher re-hospitalization rates (24% Vs.0.0%, p=0.54) within 6 months following indexed relapse.

CONCLUSION

In IBD patients, cryptosporidiosis can cause significant illness leading to increased need for hospitalization. In the absence of appropriate stool studies, cryptosporidiosis can be misdiagnosed as disease relapse and lead to inappropriate therapy. Nitazoxanide appears to be effective along with supportive therapy.

Crohn’s disease genotypes of patients in remission vs relapses after infliximab discontinuation

AIM: To investigate genetic differences between Crohn’s disease (CD) patients with a sustained remission vs relapsers after discontinuing infliximab while in corticosteroid-free remission.

METHODS: Forty-eight CD patients received infliximab and were in full corticosteroid-free clinical remission but then discontinued infliximab for reasons other than a loss of response, were identified by review of an electronic database and charts. Infliximab-associated remission was defined as corticosteroid-free plus normalization of clinical disease activity [CD activity index (CDAI) < 150] during follow-up visits based on physician global assessments. A CD relapse (loss of infliximab-induced remission) was clinically defined as a physician visit for symptoms of disease activity (CDAI > 220) and a therapeutic intervention with CD medication(s), or a hospitalization with complications related to active CD. Genetic analyses were performed on samples from 14 patients (n = 6 who had a sustained long term remission after stopping infliximab, n = 8 who rapidly relapsed after stopping infliximab). Nucleotide-binding oligomerization domain 2 (NOD2)/caspase activation recruitment domain 15 (CARD15) polymorphisms (R702W, G908R and L1007fs) and the inflammatory bowel disease 5 (IBD5) polymorphisms (IGR2060a1 and IGR3081a1) were analyzed in each group.

RESULTS: Five single nucleotide polymorphisms of IBD5 and NOD2/CARD15 genes were successfully analyzed for all 14 subjects. There was no significant increase in frequency of the NOD2/CARD15 polymorphisms (R702W, G908R and L1007fs) and the IBD5 polymorphisms (IGR2060a1 and IGR3081a1) in either group of patients; those whose disease relapsed rapidly or those who remained in sustained long term remission following the discontinuation of infliximab. Nearly a third of patients in full clinical remission who stopped infliximab for reasons other than loss of response remained in sustained clinical remission, while two-thirds relapsed rapidly. There was a marked difference in the duration of clinical remission following discontinuance of infliximab between the two groups. The patients who lost remission did so after 1.0 years ± 0.6 years, while those still in remission were at the time of this study, 8.1 years ± 2.6 years post-discontinuation of infliximab, P < 0.001. The 8 patients who had lost remission after discontinuing infliximab had a mean number of 5 infusions (range 3-7), with a mean treatment time of 7.2 mo (range 1.5 mo-15 mo). The mean duration of time from the last infusion of infliximab to the time of loss of remission was 382 d (range 20 d-701 d). The 6 patients who remained in remission after discontinuing infliximab had a mean number of 6 infusions (range 3-12), with a mean treatment duration of 12 mo (range 3.6 mo-32 mo) (P = 0.45 relative to those who lost remission).

CONCLUSION: There are no IBD5 or NOD2/CARD15 mutations that predict which patients might have sustained remission and which will relapse rapidly after stopping infliximab.

Thalidomide induces mucosal healing in Crohn's disease: case report

Crohn's disease is a chronic inflammatory disorder of the gastrointestinal tract that is defined by relapsing and remitting episodes. Tumor necrosis factor alpha (TNF-α) appears to play a central role in the pathophysiology of the disease. Standard therapies for inflammatory bowel disease fail to induce remission in about 30% of patients. Biological therapies have been associated with an increased incidence of infections, especially infection by Mycobacterium tuberculosis (Mtb). Thalidomide is an oral immunomodulatory agent with anti-TNF-α properties. Recent studies have suggested that thalidomide is effective in refractory luminal and fistulizing Crohn's disease. Thalidomide costimulates T lymphocytes, with greater effect on CD8+ than on CD4+ T cells, which contributes to the protective immune response to Mtb infection. We present a case of Crohn's disease with gastric, ileal, colon and rectum involvement as well as steroid dependency, which progressed with loss of response to infliximab after three years of therapy. The thorax computed tomography scan demonstrated a pulmonary nodule suspected to be Mtb infection. The patient was started on thalidomide therapy and exhibited an excellent response.
