Are patients with inflammatory bowel disease on chronic immunosuppressive therapy at increased risk of cervical high-grade dysplasia/cancer? A meta-analysis

Is there room for immunomodulators in ulcerative colitis?

Introduction: The management of patients with ulcerative colitis (UC) has evolved over the past few decades. While aminosalicylates remain the mainstay of induction and maintenance therapy in patients with mild-to-moderate UC, the advent of biologic agents and novel oral small molecules has substantively changed the treatment landscape for patients with moderate-to-severe disease and confounded the role of traditional immunomodulators (IMMs) such as thiopurines and methotrexate in the UC management algorithm.Areas covered: We summarize the mechanism of action of thiopurines and methotrexate, identify clinical parameters for their use, and appraise the evidence supporting the efficacy and safety of IMMs in UC as both monotherapy and in combination with other therapies, emphasizing on prospective, controlled data.Expert opinion: With the advent of several classes of highly effective treatments for UC, emergence of data demonstrating no benefit of IMMs over placebo, and concerns about the relative safety profile of long-term IMM exposure, we propose that the role of thiopurines or methotrexate be restricted to patients with milder disease failing to maintain corticosteroid-free remission on aminosalicylates alone or in combination therapy with tumor necrosis factor antagonists in patients with moderate-to-severe UC.

British Society of Gastroenterology consensus guidelines on the management of inflammatory bowel disease in adults

Ulcerative colitis and Crohn's disease are the principal forms of inflammatory bowel disease. Both represent chronic inflammation of the gastrointestinal tract, which displays heterogeneity in inflammatory and symptomatic burden between patients and within individuals over time. Optimal management relies on understanding and tailoring evidence-based interventions by clinicians in partnership with patients. This guideline for management of inflammatory bowel disease in adults over 16 years of age was developed by Stakeholders representing UK physicians (British Society of Gastroenterology), surgeons (Association of Coloproctology of Great Britain and Ireland), specialist nurses (Royal College of Nursing), paediatricians (British Society of Paediatric Gastroenterology, Hepatology and Nutrition), dietitians (British Dietetic Association), radiologists (British Society of Gastrointestinal and Abdominal Radiology), general practitioners (Primary Care Society for Gastroenterology) and patients (Crohn's and Colitis UK). A systematic review of 88 247 publications and a Delphi consensus process involving 81 multidisciplinary clinicians and patients was undertaken to develop 168 evidence- and expert opinion-based recommendations for pharmacological, non-pharmacological and surgical interventions, as well as optimal service delivery in the management of both ulcerative colitis and Crohn's disease. Comprehensive up-to-date guidance is provided regarding indications for, initiation and monitoring of immunosuppressive therapies, nutrition interventions, pre-, peri- and postoperative management, as well as structure and function of the multidisciplinary team and integration between primary and secondary care. Twenty research priorities to inform future clinical management are presented, alongside objective measurement of priority importance, determined by 2379 electronic survey responses from individuals living with ulcerative colitis and Crohn's disease, including patients, their families and friends.

Anticipatory care of children and adolescents with inflammatory bowel disease: a primer for primary care providers

PURPOSE OF REVIEW

About 10-20% of patients with newly diagnosed inflammatory bowel disease (IBD) are under 18 years of age, with incidence increasing in young children. Children with IBD have unique healthcare needs, which require coordination between primary care providers and pediatric gastroenterologists to provide appropriate care. This review highlights some key elements of anticipatory care in pediatric IBD, including vaccination, risk of serious infection and malignancy, psychosocial and educational needs, and cannabis use.

RECENT FINDINGS

Therapies for IBD that include anti-tumor necrosis factor medications, especially when combined with corticosteroids are associated with higher risks of serious infections. Vaccination remains the best way to prevent infections. Live vaccinations should be avoided during immunosuppression, but the schedule should be otherwise completed, including vaccination for influenza, pneumococcus and meningococcus, and human papillomavirus. Malignancy risk is increased in IBD patients, both because of disease factors and resulting from immunomodulatory medications. Children with IBD are at risk for mental health disorders and negative educational outcomes, so identification of at-risk children and early intervention are important.

SUMMARY

High-quality care in pediatric IBD requires coordination between pediatric gastroenterologists and primary care providers, with careful attention paid to the specific needs of children with IBD.

Canadian Association of Gastroenterology Clinical Practice Guideline for the Medical Management of Pediatric Luminal Crohn's Disease

BACKGROUND & AIMS

We aim to provide guidance for medical treatment of luminal Crohn's disease in children.

METHODS

We performed a systematic search of publication databases to identify studies of medical management of pediatric Crohn's disease. Quality of evidence and strength of recommendations were rated according to the GRADE (Grading of Recommendation Assessment, Development, and Evaluation) approach. We developed statements through an iterative online platform and then finalized and voted on them.

RESULTS

The consensus includes 25 statements focused on medical treatment options. Consensus was not reached, and no recommendations were made, for 14 additional statements, largely due to lack of evidence. The group suggested corticosteroid therapies (including budesonide for mild to moderate disease). The group suggested exclusive enteral nutrition for induction therapy and biologic tumor necrosis factor antagonists for induction and maintenance therapy at diagnosis or at early stages of severe disease, and for patients failed by steroid and immunosuppressant induction therapies. The group recommended against the use of oral 5-aminosalicylate for induction or maintenance therapy in patients with moderate disease, and recommended against thiopurines for induction therapy, corticosteroids for maintenance therapy, and cannabis in any role. The group was unable to clearly define the role of concomitant immunosuppressants during initiation therapy with a biologic agent, although thiopurine combinations are not recommended for male patients. No consensus was reached on the role of aminosalicylates in treatment of patients with mild disease, antibiotics or vedolizumab for induction or maintenance therapy, or methotrexate for induction therapy. Patients in clinical remission who are receiving immunomodulators should be assessed for mucosal healing within 1 year of treatment initiation.

CONCLUSIONS

Evidence-based medical treatment of Crohn's disease in children is recommended, with thorough ongoing assessments to define treatment success.

Ulcerative Colitis

Ulcerative colitis (UC) is a chronic inflammatory bowel disease that can involve any aspect of the colon starting with mucosal inflammation in the rectum and extending proximally in a continuous fashion. Typical symptoms on presentation are bloody diarrhea, abdominal pain, fecal urgency, and tenesmus. In some patients, extraintestinal manifestations may predate the onset of gastrointestinal symptoms. A diagnosis of UC is made on the basis of presenting symptoms consistent with UC as well as endoscopic evidence showing continuous and diffuse colonic inflammation that starts in the rectum. Biopsies of the colon documenting chronic inflammation confirm the diagnosis of UC. Most cases are treated with pharmacological therapy to first induce remission and then to maintain a corticosteroid-free remission. There are multiple classes of drugs used to treat the disease. For mild to moderate UC, oral and rectal 5-aminosalycilates are typically used. In moderate to severe colitis, medication classes include thiopurines, biological agents targeting tumor necrosis factor and integrins, and the small-molecule Janus kinase inhibitors. However, in up to 15% of cases, patients in whom medical therapy fails or who have development of dysplasia secondary to their long-standing colitis will require surgical treatment. Finally, to minimize the complications of UC and adverse events from medications, a working collaboration between primary care physicians and gastroenterologists is necessary to make sure that vaccinations are optimized and that patients are screened for colon cancer, skin cancer, bone loss, depression, and other treatable and preventable complications.

Beyond pregnancy, women's health in inflammatory bowel disease

PURPOSE OF REVIEW

Women's health includes comprehensive physical, mental and preventive care. This section will provide an overview of some of the most common disorders that can impact the health and quality of life (QOL) of women with inflammatory bowel diseases (IBDs).

RECENT FINDINGS

Women with IBD are at higher risk for cervical dysplasia compared to healthy controls with most cases preventable with vaccination. Current rates of cervical cancer screening and human papilloma virus vaccination remain low. Irritable bowel syndrome is highly prevalent among women with IBD and may present with similar symptoms. In addition, gastrointestinal symptoms may worsen during the menstrual cycle. Evaluation for active inflammation and infection should be undertaken prior to changing IBD medications. Fecal incontinence is prevalent but highly underreported in women with IBD. Further, sexual dysfunction is ubiquitous in women with IBD. Many aspects of IBD impact sexual function, including side-effects of medications, changes in body image and surgical interventions.

SUMMARY

Understanding other disorders that may cause symptoms in women with IBD is important for providers to obtain a clear history, provide the appropriate treatment and improve QOL. Caring for women with IBD involves more comprehensive care beyond the treatment of active luminal inflammation.

The Treatment of Inflammatory Bowel Disease in Patients With a History of Malignancy

As patients with inflammatory bowel disease (IBD) are living longer and our medical armamentarium expands, gastroenterologists are more frequently faced with treatment decisions about patients with IBD who also have a history of malignancy. This review aims to summarize the current literature on IBD, the inherent risk of developing gastrointestinal and extra-intestinal malignancies, and the risk of malignancies associated with available biologic and immunomodulatory therapies and to discuss the overall treatment strategy for a patient with a history of malignancy.

Improving immunization strategies in patients with inflammatory bowel disease

Patients with inflammatory bowel disease (IBD) are susceptible to varieties of opportunistic infections due to immunological changes in the setting of their disease and drug-induced immunosuppression. Even though numerous infections can be prevented by vaccine, vaccination in IBD patients is inadequate. Data showed only 9% were vaccinated against pneumococcal infection and 28% described commonly receiving influenza vaccine. This review article discusses the recent immunizations against influenza virus; pneumococcal infection; human papilloma virus; tetanus, diphtheria and pertussis; measles, mumps and rubella; varicella zoster; and herpes zoster for individuals diagnosed with IBD and those patients with drug-related immunosuppression. In addition, this review discusses concerns about IBD patients planning to travel abroad. Immunization status and screening for opportunistic infection need to be addressed in IBD patients at the time of diagnosis and they should be vaccinated accordingly. Generally, standard vaccination strategies should be pursued in IBD patients, although live vaccines should be avoided while they are not immunocompetent.

Preventive Health Care Among Postpartum Women With Inflammatory Bowel Disease: Results From the PIANO Registry

BACKGROUND

Health care maintenance (HCM) is reduced among inflammatory bowel disease (IBD) patients. This study aims to characterize rates of HCM in a closely monitored subpopulation-postpartum women with IBD-and identify predictors of noncompliance.

METHODS

A national prospective pregnancy registry was utilized to collect completion rates of HCM recommendations (cervical cancer screening; osteoporosis screening; pneumococcal, hepatitis A, hepatitis B, and influenza vaccines). Completion of a recommendation at least once during follow-up was sufficient, except for influenza vaccine, which was assessed yearly. Patients were classified by drug exposures: immunomodulator (Group A), biologic (Group B), combination therapy (Group AB), and unexposed. Confounders assessed were steroid exposure, IBD flare, IBD care site, primary care provider (PCP) access, marital status, income, education level, and race.

RESULTS

There were 628 postpartum IBD women with at least 1 year of follow-up. HCM rates were as follows: cervical cancer screening (84%), osteoporosis screening (54%), pneumococcal (50%), hepatitis A (61%), hepatitis B (81%), and influenza (72%) vaccines. The unexposed group demonstrated lower pneumococcal vaccination rates than groups A, B, and AB. Group B demonstrated lower cervical cancer screening rates than the unexposed. PCP access and low education predicted hepatitis vaccine noncompliance. Unmarried status and low income predicted cervical cancer screening noncompliance. Low income predicted influenza vaccine noncompliance.

CONCLUSIONS

Postpartum women have multiple providers, yet they complete HCM at suboptimal rates. Risk factors include biologic exposure, unmarried status, low income, low education, and access to a PCP. Awareness among providers and patients is important and needs to be enhanced.

The Impact of Inflammatory Bowel Disease in Canada 2018: Children and Adolescents with IBD

Canada has among the highest rates of childhood-onset IBD in the world. Over 7000 children and youth under 18 years old are living with IBD in Canada, and 600 to 650 children under 16 years old are diagnosed annually. While the peak age of onset of IBD is highest in the second and third decades of life, over the past two decades incidence has risen most rapidly in children under 5 years old. The treatment of children with IBD presents important challenges including therapeutic choices, risk of adverse events to medications, psychosocial impact on the child and family, increased cost of health care and the implications of the transition from pediatric to adult care. Despite the unique circumstances faced by children and their families, there is a lack of research to help understand the causes of the rising incidence and the best therapies for children with IBD. Scientific evidence—and specifically clinical trials of pharmaceuticals—are too often extrapolated from adult research. Health care providers must strive to understand the unique impact of childhood-onset IBD on patients and families, while researchers must expand work to address the important needs of this growing patient population.

The risk for opportunistic infections in inflammatory bowel disease with biologics: an update

Crohn's disease and Ulcerative Colitis are forms of inflammatory bowel disease (IBD), chronic diseases treated with medical and surgical therapy. Patients with IBD are treated with potent immunomodulatory agents, leading to immunosuppression, and the potential for opportunistic infections. In 2014, the ECCO guidelines were released to guide the prevention, diagnosis and treatment of a variety of these opportunistic infections. Since 2014, there have been a number of new agents released as well as a significant expansion in our knowledge of the safety profile of IBD medications. In this article, we review the literature after 2014 regarding opportunistic infections and updates on safety data. Areas covered: We review updates in immunomodulatory therapies for IBD and opportunistic infections since the 2014 ECCO guidelines were published. Expert commentary: The prevention, diagnosis, and treatment of opportunistic infections continue to evolve, as new drugs are approved, and the use of a combination of biologic agents are considered for therapy in clinical trials. What causes some patients to fail to respond to vaccination, or for others to develop severe infections, remains unclear. Improved risk stratification for opportunistic infections in IBD patients and updated ECCO 2014 guidelines would be of significant benefit.

Update on Vaccinating the Patient With Inflammatory Bowel Disease

PURPOSE OF REVIEW

Patients with inflammatory bowel disease (IBD) are at increased risk of infectious diseases independent of their immunosuppression status, and yet, studies suggest that this population is not receiving standard vaccinations at the same rate as the general population. This review seeks to understand why IBD patients may not be receiving recommended immunizations and to provide guidelines on vaccinating this vulnerable population.

RECENT FINDINGS

Inactive vaccines are recommended for patients with IBD regardless of immunosuppression status due to the increased risk for many vaccine-preventable illnesses. Certain live vaccines can be administered to the immunocompromised patient with IBD. Additionally, many patients with IBD will be immunosuppressed some time in their disease course, further increasing their risk for infection. Despite this understanding, patients with IBD have poor vaccination rates. Inadequate knowledge, limited time with patients, and lack of consensus as to who is responsible for identifying and administering vaccinations are some of the most important barriers to vaccinating the patient with IBD. In this review, we discuss guidelines for vaccinating both the immunocompetent and immunosuppressed patient with IBD as well as provide vaccine-specific recommendations. The evidence suggests that patients with IBD are not receiving recommended vaccinations because of misconceptions on the part of patients as well as a paucity of knowledge by their health care team. Educational programs can be successfully implemented to increase knowledge about appropriate vaccinations and can ultimately increase vaccine uptake among patients with IBD. In the end, gastroenterologists and primary care physicians must work together with their patients with IBD to ensure that recommended vaccinations are administered.

Risk Factors and Clinical Outcomes of Head and Neck Cancer in Inflammatory Bowel Disease: A Nationwide Cohort Study

BACKGROUND

Immunosuppressed inflammatory bowel disease (IBD) patients are at increased risk to develop extra-intestinal malignancies. Immunosuppressed transplant patients show increased incidence of head and neck cancer with impaired survival. This study aims to identify risk factors for oral cavity (OCC) and pharyngeal carcinoma (PC) development in IBD, to compare clinical characteristics in IBD with the general population, and to assess the influence of immunosuppressive medication on survival.

METHODS

We retrospectively searched the Dutch Pathology Database to identify all IBD patients with OCC and PC between 1993 and 2011. Two case-control studies were performed: We compared cases with the general IBD population to identify risk factors, and we compared cases with non-IBD cancer patients for outcome analyses.

RESULTS

We included 66 IBD patients and 2141 controls with OCC, 31 IBD patients and 1552 controls with PC, and 1800 IBD controls. Age at IBD diagnosis was a risk factor for OCC development, Crohn's disease (CD; odds ratio [OR], 1.04; 95% confidence interval [CI], 1.02-1.07), and ulcerative colitis (UC; OR, 1.03; 95% CI, 1.01-1.06). For PC, this applied to UC (OR, 1.05; 95% CI, 1.01-1.06). IBD OCC cases showed impaired survival (P = 0.018); in PC, survival was similar. There was no effect of immunosuppression on survival. Human papillomavirus (HPV) testing of IBD cases revealed 52.2% (12/23) HPV-positive oropharyngeal carcinomas (OPCs).

CONCLUSION

This study shows that IBD is associated with impaired OCC survival. Higher age at IBD diagnosis is a risk factor for OCC development. We found no influence of immunosuppression on survival; 52.2% of OPC in IBD contained HPV.

Women with inflammatory bowel diseases have a suboptimal cervical cancer screening rate and are not aware of the recommended human papilloma virus vaccine

The aim of the study was to assess the self-reported cervical cancer screening rate among patients with inflammatory bowel diseases (IBD) and patient attitude towards human papilloma virus (HPV) vaccination. A self-designed survey was conducted in hospitalized IBD patients. The survey comprised demographic data, questions regarding cervical smear test frequency and vaccinations recommended for an IBD patient. Randomly, patients completed the survey with a physician present to determine question comprehension. In order to provide test-retest reliability a group of 10 patients completed it twice. Survey data from 150 IBD patients (mean age: 36 years, SD ± 13; mean IBD duration: 10 years, SD ± 6.5) were analyzed. Fifteen percent of the patients reported irregular cervical testing and 15% do not remember when having had a previous cervical testing performed. Only 69% of the patients undergo testing regularly; 30% annually, 32% every 2-3 years; 7% every 5 years. The mean age of patients tested regularly was 22 years, vs. 32 years tested irregularly (p < .001). Only 10% of women claimed that HPV vaccine is recommended for an IBD patient. There is a low adherence to the recommendations regarding cervical cancer screening and prophylaxis. Better multi-disciplinary cooperation between patients and physicians is required to improve patient education and outcomes.

Women's Health in Inflammatory Bowel Disease

About half of all inflammatory bowel disease (IBD) patients are women. It is important that physicians are aware of gender-specific needs women with IBD may have. This review covers general and specific women's health issues related to their IBD. It is intended to be practical and give a brief overview of topics including body image, menstruation, contraception, cervical cancer screening, preconception counseling, anxiety, depression, pregnancy, breastfeeding, menopause, skin exams, vaccines, laboratory monitoring and bone health.

Thiopurines in Inflammatory Bowel Disease: New Findings and Perspectives

Thiopurines, available as azathioprine, mercaptopurine, and thioguanine, are immunomodulating agents primarily used to maintain corticosteroid-free remission in patients with inflammatory bowel disease. To provide a state-of-the-art overview of thiopurine treatment in inflammatory bowel disease, this clinical review critically summarises the available literature, as assessed by several experts in the field of thiopurine treatment and research in inflammatory bowel disease.

Malignancy and Mortality in Pediatric-onset Inflammatory Bowel Disease: A Systematic Review

BACKGROUND

Cancer and death are the most severe outcomes that affect patients with inflammatory bowel disease (IBD). These outcomes are even more severe if they occur at a young age but are rare, even in the general population. We conducted a systematic review to provide an overview of all reported pediatric (PIBD) patients with severe outcome.

METHODS

A literature search identified publications that reported development of cancer or fatal outcome in PIBD patients. Studies were eligible for inclusion when (1) article written in English, (2) original data, (3) individual patient information, (4) full text available, (5) study population consisting of patients diagnosed with IBD under the age of 19 years, and (6) who developed malignancy or fatality at any point later in life.

RESULTS

A total of 98 included studies comprised data of 271 PIBD patients who developed cancer and/or fatal outcome at any point later in life. Meta-analysis demonstrated an increased risk for cancer in PIBD patients (pooled standardized incidence ratio 2.23, 95% CI: 1.98-2.52). The most frequent type of non-fatal cancer was lymphoma, whereas colorectal carcinomas were the most frequently reported type of fatal cancer in PIBD patients and were particularly associated with primary sclerosing cholangitis. The majority of patients with noncancer-related fatal outcomes were diagnosed with ulcerative colitis and most often died due to infectious complications or severe disease-associated complications.

CONCLUSIONS

The data in this review confirm that PIBD associated malignancy and mortality are rare and detailed clinical characteristics are limited. Prospective and international collaborations are needed to obtain more detailed patient-specific information, which is necessary to investigate the relationship between severe outcomes in PIBD patients and the currently used therapeutic strategies. 10.1093/ibd/izx104_video1izx104_Video5754026434001.

Neoplasia and Precursor Lesions of the Female Genital Tract in IBD: Epidemiology, Role of Immunosuppressants, and Clinical Implications

In this review the risk of breast, ovarian, and endometrial cancer and cervical and vulvovaginal (pre)malignant abnormalities in patients with inflammatory bowel disease (IBD) with or without immune suppressive treatment will be discussed. So far, this has not been studied thoroughly and large studies taking into account diverse potential confounding factors are lacking. IBD per se has not been associated with development of cervical cancer, yet patients with Crohn's disease who smoke, have a younger age at diagnosis or who use(d) thiopurines might be more at risk. Other immunosuppressive medication seems not to increase this risk, however, as evidence at this point is incomplete, physician awareness and prevention by lifestyle counseling, HPV vaccination and (intensified) screening are warranted. The risk for breast, endometrial, ovarian, and vulvovaginal cancer in IBD patients appears to be comparable to the background population, although for breast cancer this may even be decreasedin Crohn's disease specifically. Immunosuppressive medication in general does not seem to alter this risk. Earlier and more frequent screening for breast cancer than currently conducted in general nationwide screening programs is not recommended at this moment. Current literature suggests a much lower overall malignancy recurrence rate in IBD patients than has been observed previously. More importantly, immune suppressive medication does not appear to increase the recurrence risk. Robust epidemiologic data on female genital tract cancer are needed.

Systematic review with meta-analysis: thiopurines decrease the risk of colorectal neoplasia in patients with inflammatory bowel disease

BACKGROUND

Patients with inflammatory bowel disease (IBD) have a high risk of developing colorectal neoplasia.

AIM

To investigate whether thiopurines can decrease the risk of developing colorectal neoplasia in patients with ulcerative colitis (UC) or Crohn's disease (CD).

METHODS

We conducted a meta-analysis of 24 observational studies involving 76,999 participants to evaluate the risks of developing colorectal neoplasia in IBD patients receiving thiopurine treatment. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) for the risks of colorectal neoplasia were calculated using a random-effects model.

RESULTS

The overall pooled estimate revealed a protective effect of thiopurine use on colorectal neoplasia in patients with IBD (OR = 0.63, 95% CI 0.46-0.86). The effect was significant in UC patients (OR = 0.67, 95% CI 0.45-0.98), but was not significant in CD patients (OR = 1.06, 95% CI 0.54-2.09). Thiopurines exposure significantly decreased the risk of colorectal cancer (CRC) (OR = 0.65, 95% CI 0.45-0.96) and advanced colorectal neoplasia (CRC and/or high-grade dysplasia) (OR = 0.62, 95% CI 0.44-0.89), but did not decrease the risk of dysplasia alone (OR = 0.90, 95% CI 0.37-2.21). Tendencies towards the protective effect of thiopurines were distinct in clinic-based studies (OR = 0.59, 95% CI 0.42-0.82) and case-control studies (OR = 0.40, 95% CI 0.26-0.62), but not in population-based studies (OR = 0.95, 95% CI 0.55-1.62) and cohort studies (OR = 0.98, 95% CI 0.81-1.18). Interestingly, studies conducted in Europe (OR = 0.48, 95% CI 0.31-0.77), rather than in North America (OR = 0.91, 95% CI 0.67-1.24), showed the protective effect of thiopurines.

CONCLUSIONS

This meta-analysis revealed an antineoplastic effect of thiopurines on colorectal neoplasia in patients with IBD, particularly amongst patients with UC.

Human Immunodeficiency Virus (HIV)- and Non-HIV-Associated Immunosuppression and Risk of Cervical Neoplasia

OBJECTIVE

To estimate the risk of cervical intraepithelial neoplasia grade 2, 2-3, 3, adenocarcinoma in situ, or cancer (CIN 2 or worse) among women with human immunodeficiency virus (HIV)- and non-HIV-associated immunosuppression.

METHODS

We performed a case-control study of 20,146 women with incident CIN 2 or worse and 5:1 age-matched, incidence-density selected women in a control group (n=100,144) enrolled in an integrated health care system from 1996 to 2014. Adjusted rate ratios (RRs) from conditional logistic regression were obtained for HIV status (stratified by CD4 T-cells), solid organ transplant history, and immunosuppressive medication use.

RESULTS

Risk of CIN 2 or worse was increased among women with HIV (n=36 women in the case group and 79 women in the control group; adjusted RR 2.0, 95% CI 1.3-3.0) compared with those without HIV and in solid organ transplant recipients (n=51 women in the case group and 68 women in the control group; RR 3.3, 95% CI 2.3-4.8) compared with women without a prior transplant. The highest risks were among women with HIV and less than 200 CD4 T-cells/microliter (n=9 women in the case group and eight women in the control group; RR 5.6, 95% CI 2.1-14.7) compared with those without HIV and in solid organ transplant recipients prescribed three or greater immunosuppressive medication classes (n=32 women in the case group and 33 women in the control group; RR 4.1, 95% CI 2.5-6.8) compared with women without a prior transplant and zero medication classes. No increased risks were observed for women with HIV and 500 or greater CD4 T-cells/microliter (n=9 women in the case group and 43 women in the control group; RR 0.8, 95% CI 0.4-1.7) compared with those without HIV or women without prior solid organ transplantation prescribed two or fewer immunosuppressive medication classes (n=1,262 women in the case group and 6,100 women in the control group; RR 0.95, 95% CI 0.89-1.01) compared with women without and a prior transplant and zero medication classes.

CONCLUSION

Risk of CIN 2 or worse is increased in women with a prior solid organ transplant or who have HIV and CD4 cells/microliter less than 500 but not in women with HIV and higher CD4 levels or in women without a prior solid organ transplant but who are prescribed only one or two immunosuppressive medication classes.

Vaccination and Health Maintenance Issues to Consider in Patients With Inflammatory Bowel Disease

Patients with inflammatory bowel disease (IBD) do not receive routine preventive care at the same rate as the general population. IBD places patients at increased risk for developing vaccine-preventable illnesses. This risk is further exacerbated by immunosuppressive therapy. This article highlights the necessary vaccinations for IBD patients and the timing of vaccination for immunosuppressed patients, and discusses the health maintenance needs and preventive care issues related to heart disease, smoking, osteoporosis, mental health, cervical cancer, and skin cancer.

Intestinal and Nonintestinal Cancer Risks for Patients with Crohn's Disease

Crohn's disease (CD) is a chronic inflammatory disease that confers a higher risk of cancer than in the general population. New, large, population-based studies in the past decade show that patients with CD are at higher risk of colorectal, small bowel, melanoma, and cervical cancer. Patients who use thiopurines are at additional risk of development of lymphoma and nonmelanoma skin cancer. Preventive surveillance for cancers of the colorectum, skin, and uterine cervix is advised.

Receptive Anal Intercourse in Patients with Inflammatory Bowel Disease: A Clinical Review

Receptive anal intercourse and its association with sexually transmitted infections and human papillomavirus-related anal dysplasia has been well studied in various at-risk groups including men who have sex with men. However, the relationship between receptive anal intercourse and its potential complications in patients with inflammatory bowel disease is not fully understood. This narrative review discusses sexually transmitted infections and anal dysplasia in patients with inflammatory bowel disease who engage in receptive anal intercourse and the lack of evidence-based data to guide clinical practice. It addresses the psychosocial effects of stigmatization in these patients and its consequences in the clinical encounter. We review the need for sufficient data on infection, cancer prevention, and precoital and postcoital hygienic practices with hopes that future studies establish standardized guidelines and recommendations.

Screening Women at High Risk for Cervical Cancer: Special Groups of Women Who Require More Frequent Screening

The updated cervical cancer screening guidelines recommend that women at average risk who have negative screening results undergo cervical cytological testing every 3 to 5 years. These recommendations do not pertain to women at high risk for cervical cancer. This article reviews recommendations for cervical cancer screening in women at high risk.

Anal Neoplasia in Inflammatory Bowel Disease: Classification Proposal, Epidemiology, Carcinogenesis, and Risk Management Perspectives

Patients with inflammatory bowel disease [IBD] may develop, similarly to individuals from general population, rare cases of human papilloma virus [HPV]-related anal canal squamous cell carcinoma [SCC] and intra-epithelial precursor lesions, as well as very rare cases of anal canal adenocarcinoma. Patients with chronic perianal Crohn's disease [CD] are at substantial risk of developing SCC or adenocarcinoma from the fistula-lining epithelium, as well as SCC or adenocarcinoma arising from chronic anorectal ulcerations or strictures. Based on this lesion stratification, we provide in this review tailored incidence estimates and we propose an IBD-specific classification of all types of anal neoplasia that may occur in patients with IBD. After reviewing putative carcinogenesis of all types of neoplasia, we conclude that HPV vaccination could reduce the incidence of HPV-related lesions, although an anal screening programme related to these lesions is not mandatory on the sole basis of IBD. By contrast, we point out that all patients with chronic perianal CD should be explored in depth, including biopsies under anaesthesia and fistula curettage when necessary, in case of any change in anal symptoms ─in particular new, increasing, unexplained pain. Finally, we conclude that there is an urgent need for elaborating and evaluating surveillance algorithms in patients with chronic perianal CD, in order to avoid cancers with late diagnosis and poor prognosis.

Understanding the Cautions and Contraindications of Immunomodulator and Biologic Therapies for Use in Inflammatory Bowel Disease

Ulcerative colitis and Crohn's disease are chronic inflammatory bowel diseases for which there are no cures. These diseases are immunopathogenic, and medical treatment is centered on the temperance of a dysregulated immune response to allow mucosal healing and prevent the sequelae of fistulation and stenosis. Accordingly, the armamentarium of medications, which has expanded immensely in recent history, is not without significant infectious and neoplastic risks. Many of these untoward effects can be mitigated by screening and avoidance of contraindicated medications. This review seeks to highlight the cautions for use of immunomodulators, anticytokine, and α4-integrin antagonists. The potential adverse events are further complicated by substantial heterogeneity in disease phenotype in the inflammatory bowel disease population. Large patient registries and databases provide considerable experience and knowledge to calculate the incidence of safety outcomes. To identify rarer outcomes after prolonged therapy, more prospective studies and continued adverse event reporting will aid safe application and minimize potential harms.

Human Papillomavirus and Its Testing Assays, Cervical Cancer Screening, and Vaccination

Human papillomavirus (HPV) was found to be the causative agent for cervical cancer in the 1980s with almost 100% of cervical cancer cases testing positive for HPV. Since then, many studies have been conducted to elucidate the molecular basis of HPV, the mechanisms of carcinogenesis of the virus, and the risk factors for HPV infection. Traditionally, the Papanicolaou test was the primary screening method for cervical cancer. Because of the discovery and evolving understanding of the role of HPV in cervical dysplasia, HPV testing has been recommended as a new method for cervical cancer screening by major professional organizations including the American Cancer Society, American Society for Colposcopy and Cervical Pathology, and the American Society for Clinical Pathology. In order to detect HPV infections, many sensitive and specific HPV assays have been developed and used clinically. Different HPV assays with various principles have shown their unique advantages and limitations. In response to a clear causative relationship between high-risk HPV and cervical cancer, HPV vaccines have been developed which utilize virus-like particles to create an antibody response for the prevention of HPV infection. The vaccines have been shown in long-term follow-up studies to be effective for up to 8 years; however, how this may impact screening for vaccinated women remains uncertain. In this chapter, we will review the molecular basis of HPV, its pathogenesis, and the epidemiology of HPV infection and associated cervical cancer, discuss the methods of currently available HPV testing assays as well as recent guidelines for HPV screening, and introduce HPV vaccines as well as their impact on cervical cancer screening and treatments.

Infections in inflammatory bowel disease

Patients with inflammatory bowel disease constitute a population with a special predisposition to develop bacterial, viral and fungal infections. Iatrogenic immunosuppression, frequent contact with healthcare facilities and surgical interventions are some of the risk factors that explain why these infections are one of the main causes of morbi-mortality in this disease. Some of these infections follow a subtle and paucisymptomatic evolution; their diagnosis and management may become a real challenge for the attending physician if their screening is not systematized or they are not considered in the differential diagnosis. The objective of this review is to provide an update from a practical and concise perspective on the knowledge regarding the epidemiology, prevention, diagnosis and treatment of the most common infections.

ACG Clinical Guideline: Preventive Care in Inflammatory Bowel Disease

Recent data suggest that inflammatory bowel disease (IBD) patients do not receive preventive services at the same rate as general medical patients. Patients with IBD often consider their gastroenterologist to be the primary provider of care. To improve the care delivered to IBD patients, health maintenance issues need to be co-managed by both the gastroenterologist and primary care team. Gastroenterologists need to explicitly inform the primary care provider of the unique needs of the IBD patient, especially those on immunomodulators and biologics or being considered for such therapy. In particular, documentation of up to date vaccinations are crucial as IBD patients are often treated with long-term immune-suppressive therapies and may be at increased risk for infections, many of which are preventable with vaccinations. Health maintenance issues addressed in this guideline include identification, safety and appropriate timing of vaccinations, screening for osteoporosis, cervical cancer, melanoma and non-melanoma skin cancer as well as identification of depression and anxiety and smoking cessation. To accomplish these health maintenance goals, coordination between the primary care provider, gastroenterology team and other specialists is necessary.

Practical Approaches to "Top-Down" Therapies for Crohn's Disease

Crohn's disease (CD) is a chronic, progressive, and disabling disease that leads in most cases to the development of bowel damage presenting as a fistula, abscess, or stricture. For years, therapy for Crohn's disease has been based on a "step-up" approach, in which anti-TNF agents are administered after the failure of steroids and immunosuppressants. However, recent studies have suggested that early introduction of anti-TNF agents combined with immunosuppressants can modify the natural history of the disease. Patients who could benefit more of this "top-down" strategy would be those at elevated risk of a complicated or severe inflammatory bowel disease or with factors that can predict an aggressive disease course. Therefore, the management of a patient with CD should be personalized, taking into account the patient's specific characteristics and comorbidities, disease activity, site and behavior of the disease, and predictable factors of poor prognosis. A balance between medication and potential adverse effects should be achieved, trying to avoid under or overtreatment, always discussing the different therapeutic options with the patient. The natural history of ulcerative colitis differs from CD and, to date, there is not much scientific evidence on the use of early combined immunosuppression.

The Changing Phenotype of Inflammatory Bowel Disease

It is widely known that there have been improvements in patient care and an increased incidence of Inflammatory Bowel Disease (IBD) worldwide in recent decades. However, less well known are the phenotypic changes that have occurred; these are discussed in this review. Namely, we discuss the emergence of obesity in patients with IBD, elderly onset disease, mortality rates, colorectal cancer risk, the burden of medications and comorbidities, and the improvement in surgical treatment with a decrease in surgical rates in recent decades.

Association Between Breast Cancer Recurrence and Immunosuppression in Rheumatoid Arthritis and Inflammatory Bowel Disease: A Cohort Study

OBJECTIVE

Breast cancer recurrence may be promoted by immunosuppression due to decreased immune surveillance. The aim of this study was to examine the rates of breast cancer recurrence in patients with immune-mediated disease and treated breast cancer who received therapy with methotrexate, thiopurines, or anti-tumor necrosis factor (anti-TNF).

METHODS

Three retrospective cohort studies within Medicare (2000-2012) included women with rheumatoid arthritis (RA) or inflammatory bowel disease (IBD) who underwent surgery for primary breast cancer. Recurrent or second primary breast cancers occurring more than 365 days after the initial surgery were identified. Separate Cox regression models were used to examine the risk of cancer recurrence in patients treated with methotrexate, thiopurines, or anti-TNF agents after surgery, each compared with no use. Analyses were matched for type of breast surgery and receipt and type of adjuvant therapy.

RESULTS

Across all medication groups, 107 women experienced breast cancer recurrence during 5,196 person-years. The incidence rates were 20.3 and 19.6 per 1,000 person-years in methotrexate users and nonusers, respectively, 32.3 and 17.6 in thiopurine users and nonusers, respectively, and 22.3 and 19.5 in anti-TNF users and nonusers, respectively. There was no significantly increased risk of breast cancer recurrence with use of methotrexate (adjusted hazard ratio [HR] 1.07, 95% confidence interval [95% CI] 0.67-1.69), anti-TNF therapy (HR 1.13, 95% CI 0.65-1.97), or thiopurines (HR 2.10, 95% CI 0.62-7.14).

CONCLUSION

The risk of breast cancer recurrence in patients who received methotrexate, thiopurine, or anti-TNF therapy was not statistically significantly increased, although we cannot rule out a 2-fold or greater increased risk in those treated with thiopurines. These data provide reassurance to clinicians choosing to start methotrexate or anti-TNF therapy in RA or IBD patients with treated breast cancer.

Vaccinating Patients With Inflammatory Bowel Disease

Patients with inflammatory bowel disease (IBD) are not vaccinated at the same rate as general medical patients. IBD places patients at increased risk for developing vaccine-preventable illnesses, and this risk is further exacerbated by immunosuppressive therapy. Therefore, gastroenterologists should familiarize themselves with health maintenance measures pertaining to patients with IBD. This article highlights the vaccinations required for patients with IBD, especially those who are immunosuppressed: influenza; pneumococcal pneumonia; hepatitis A and B viruses; human papilloma virus; meningococcal disease; tetanus, diphtheria, and pertussis; measles, mumps, and rubella; varicella zoster; and herpes zoster. This article also discusses issues regarding patients with IBD who travel outside of the United States, as well as highlights and provides suggestions for areas of quality improvement that are needed in the field.

Making Sense of Cervical Cancer Screening Guidelines and Recommendations

OPINION STATEMENT

Since the publication of the American Cancer Society (ACS)/American Society for Colposcopy and Cervical Pathology (ASCCP)/American Society for Clinical Pathology (ASCP) clinical guidelines in 2012, the majority of practice organizations have reached a consensus on screening recommendations for a low-risk population. These guidelines were based on a thorough review of the evidence with reproducible methods to obtain high-quality, generalizable guidelines. Despite the strength of the evidence based recommendations comprising these guidelines, limitations in physician understanding and compliance remain with respect to reaching an unscreened population and defining and caring for women who are at "high risk." "High-risk" patients are poorly characterized but should include women with a history of a prior abnormal screening, as data has shown a subsequent increased risk of cervical intraepithelial neoplasia grade 2 (CIN2) or greater, even after treatment. These women warrant more intense screening than the general population-though there are no evidence-based guidelines for optimized screening protocols in this population. Emerging data in cervical cancer screening this year includes the FDA approval of primary high-risk human papillomavirus (HPV) testing. While the data is promising, its role in clinical practice, impact on rates of colposcopy in a non-study population, and long-term outcomes are not fully understood, and ongoing research is needed. Challenges remain in this shifting environment on the optimal interval and modality for cervical cancer screening to provide the greatest benefit in detection of precancerous lesions while minimizing the harm of overtreatment. While rapid advancements in research provide improved knowledge on how to treat and prevent this disease, it is often difficult for providers across multiple specialties to remain abreast of these changes and to educate their patients about the most current recommendations. Ultimately, provider and patient education is critical both for improving primary prevention with HPV vaccination, as well as for the uptake of evidence-based screening and management guidelines aimed at detecting and treating precancerous changes of the cervix.

Preventative care for patients with inflammatory bowel disease in the Veterans Health Administration

Patients with inflammatory bowel disease (IBD) have underlying immune dysregulation. Immunosuppressive medications put them at risk of infection. This study assessed rates of recommended vaccinations and preventative screening in patients with IBD.Nationwide data on patients diagnosed with IBD in the Veterans Health Administration (VHA) October 2004 to September 2014 were extracted. Variation in vaccination, screenings, and risk of death by demographic factors (age group, gender) were estimated in bivariate and multivariable analyses.During the 10-year study period, 62,002 patients were treated for IBD. Nonmelanoma skin cancer was found in 2.6%, and these patients more commonly accessed dermatology clinic (22.5% vs 15.2%; chi-square = 66.6; df = 1; P < 0.0001). In total, 15% received DEXA scans, especially women (34.7% vs 13.2% men; chi-square = 1415.5; df = 1; P < 0.0001). Eye manifestations were noted in 38.3% yet only 31% were referred to ophthalmology. Abnormal Pap smears were found for 15% of women <65 (compared to 5% among normal patient populations); 34% had no record of Pap smear in VHA data. Vaccination rates were modest: pneumococcal 39%; TDAP 23%; hepatitis B 3%; varicella and PPD <0.5%. In an adjusted logistic regression model, 5-year mortality was lower among those using primary care prior to IBD diagnosis (odds ratio [OR] = 0.61; 95% CI 0.55-0.68).Despite the current IBD guidelines, vaccination and preventative screening rates were unacceptably low among patients diagnosed with IBD. Interventions such as education and increased awareness may be needed to improve these rates.

Cancer Recurrence Following Immune-Suppressive Therapies in Patients With Immune-Mediated Diseases: A Systematic Review and Meta-analysis

BACKGROUND & AIMS

Physicians frequently encounter patients with immune-mediated diseases and a history of malignancy. There are limited data on the safety of immunosuppressive therapy for these patients. Published studies have been small with few events, precluding robust estimates of risk.

METHODS

We searched Medline, EMBASE, and conference proceedings for terms related to immune-mediated disease, immune-suppressive therapy, and cancer recurrence from inception to April 2015. We included 16 studies (9 of patients with rheumatoid arthritis, 8 of patients with inflammatory bowel disease, and 1 of patients with psoriasis) and stratified studies by type of immune-suppressive therapy (monoclonal antibodies to tumor necrosis factor [anti-TNF], conventional immune-modulatory agents, or no immune suppression). A random-effects meta-analysis was performed to calculate the pooled incidence rates as well as risk differences between the various treatments.

RESULTS

Our analysis included 11,702 persons contributing 31,258 person-years (p-y) of follow-up evaluation after a prior diagnosis of cancer. Rates of cancer recurrence were similar among individuals receiving anti-TNF therapy (33.8 per 1000 p-y), immune-modulator therapy (36.2 per 1000 p-y), or no immunosuppression (37.5 per 1000 p-y), but were numerically higher among patients receiving combination immune suppression (54.5 per 1000 p-y) (P > .1 for all). Subgroup analysis of new and recurrent cancers separately, type of immune-modulator therapy, or immune-mediated disease showed similar results, with no increase in risk. We found similar pooled incidence values for new or primary cancers when immunosuppression was initiated within 6 years (33.6 per 1000 p-y for immune-modulatory agents and 43.7 per 1000 p-y for anti-TNF agents) vs more than 6 years after the index cancer (32.9 per 1000 p-y for immune-modulatory agents, P = .86; and 21.0 per 1000 p-y for anti-TNF agents, P = .43).

CONCLUSIONS

In a meta-analysis of 16 studies, we observed similar rates of cancer recurrence among individuals with prior cancer who received no immunosuppression, anti-TNF therapy, immune-modulator therapy, or combination treatments. Prospective studies are needed to ascertain optimal intervals for re-initiation of immune-suppressive therapies for individuals with specific cancers.

Caring for Women with Inflammatory Bowel Disease

Ulcerative colitis and Crohn disease are chronic inflammatory diseases with typical onset in early adulthood. These diseases, therefore, can affect a woman throughout the many stages of her life, including menstruation, sexuality, pregnancy, and menopause. Unique health issues face women during these stages and can affect the course of their inflammatory bowel disease as well as treatment strategies and health maintenance. This article covers the non-pregnancy-related issues that are important in caring for women with inflammatory bowel disease. The topics of pregnancy and fertility are covered in a separate review.

Use of biologics and chemotherapy in patients with inflammatory bowel diseases and cancer

Patients with inflammatory bowel disease have an additional risk of developing cancer compared with the general population. This is due to local chronic inflammation that leads to the development of gastrointestinal cancers and the use of thiopurines, associated with a higher risk of lymphoproliferative disorders, skin cancers, or uterine cervical cancers. Similar to the general population, a previous history of cancer in inflammatory bowel disease patients increases the risk of developing a secondary cancer. Large studies have not shown an increased risk of cancer in patients treated with biologics. In this review we discuss the prevention and treatment of cancer in patients with inflammatory bowel disease.

Increased Risk of Oral Cancer in Patients With Inflammatory Bowel Diseases

BACKGROUND & AIMS

Epidemiology studies have consistently found an increased risk of oral malignancies in organ transplant recipients, patients with graft-versus-host disease, and people with human immunodeficiency virus infection. We assessed the risk of oral cancer in patients with inflammatory bowel diseases (IBD).

METHODS

We collected data on 7294 patients with IBD (3785 women) seen at Mount Sinai Medical Center, New York, from 2000 through 2011. The expected incidence of oral cancer was calculated for each sex-specific and 5-year age-specific stratum by specific incidence rates using the Surveillance, Epidemiology and End Results 18 registry data (2000-2011), adjusted for age to the 2000 United States population (census P25-1130).

RESULTS

Eleven patients (7 men) were found to have biopsy-proven oral cancer. Six patients had cancer of the tongue; 2 patients had cancer of the hard palate; and the remaining 3 had tonsillar, buccal, or mandibular sarcoma. Before the cancer diagnosis, IBD had been treated in 4 patients with azathioprine or mercaptopurine, in 1 patient with infliximab, and 3 in patients with combination of biologic agents and azathioprine; 4 of the patients had not been treated for IBD. The age- and sex-adjusted standardized incidence ratio (SIR) for oral cancer in patients with IBD was 9.77 (95% confidence interval [CI], 5.14-16.98). In women, the SIR was 12.07 (95% CI, 3.84-29.11), and in men the SIR was 8.49 (95% CI, 3.71-16.78). The age-adjusted SIR for tongue cancer was 18.91 (95% CI, 7.66-39.33): 17.06 for men (95% CI, 5.42-41.15) and 22.10 for women (95% CI, 3.70-73.01).

CONCLUSIONS

We found patients with IBD to be at increased risk for oral cancers, especially tongue cancer. Women are at higher risk than men.

Impact of New Treatments on Hospitalisation, Surgery, Infection, and Mortality in IBD: a Focus Paper by the Epidemiology Committee of ECCO

The medical management of inflammatory bowel disease has changed considerably over time with wider use of immunosuppressant therapy and the introduction of biological therapy. To what extent this change of medical paradigms has influenced and modified the disease course is incompletely known. To address this issue, an extensive review of the literature has been carried out on time trends of hospitalization, surgery, infections, cancer, and mortality rates in inflammatory bowel disease [IBD] patients. Preference was given to population-based studies but, when data from these sources were limited, large cohort studies and randomised controlled trials were also considered. In general, data on hospitalisation rates are strikingly heterogeneous and conflicting. In contrast, the consistent drop in surgery/colectomy rates suggests that the growing use of immunosuppressants and biological agents has had a positive impact on the course of IBD. Most clinical trial data indicate that the risk of serious infections is not increased in patients treated with anti-tumour necrosis factor alpha [TNFα] agents, but a different picture emerges from cohort studies. The use of thiopurines increases the risk for non-melanoma skin cancers and to a lesser extent for lymphoma and cervical cancer [absolute risk: low], whereas no clear increase in the cancer risk has been reported for anti-TNF agents. Finally, the majority of studies reported in the literature do not reveal any increase in mortality with immunosuppressant therapy or biologicals/anti-TNF agents.
