Risk of cervical cancer in women with autoimmune diseases, in relation with their use of immunosuppressants and screening: population-based cohort study

[Risks of Cancer Associated with Therapeutic Drugs for Inflammatory Bowel Disease]

Crohn's disease and ulcerative colitis are lifelong chronic inflammatory conditions, with many patients requiring ongoing immunomodulatory drug therapy for maintenance treatment. Recent therapeutic goals in inflammatory bowel disease (IBD) are not only aimed at symptomatic remission but also at achieving mucosal healing to improve the natural course of the disease. In this context, therapeutic approaches are being applied in clinical settings that involve early and appropriate use of drugs, such as immunomodulators or biologics, that have the potential to induce healing of the inflamed intestine before irreversible intestinal damage occurs. All drugs that continuously control intestinal inflammation in IBD can heal the mucosa and potentially reduce the incidence of colitis-associated bowel cancer; however, the continuous use of immunosuppressants can potentially increase the risk of malignancies. The safety issues of the drugs used in clinical practice are partly confirmed during their development processes or shortly after initial marketing, but in other cases, they are estimated through post-marketing case reports or epidemiological studies, sometimes decades after drug approval. This review explores the risks associated with malignancies related to the treatment of IBD, focusing on drugs currently approved in Republic of Korea.

Autoimmune diseases and female-specific cancer risk: A systematic review and meta-analysis

OBJECTIVES

Among the over 80 different autoimmune diseases, psoriasis (PsO), rheumatoid arthritis (RA), and ankylosing spondylitis (AS) are common representatives. Previous studies indicated a potential link with cancer risk, but suffered often from low statistical power. Thus, we aimed to synthesize the evidence and quantify the association to different female-specific cancer sites.

METHODS

The systematic review was performed according to PRISMA guidelines. A search string was developed for the databases PubMed, Web of Science, Cochrane Library and Embase. Results were screened independently by two investigators and the risk of bias was assessed using the ROBINS-E tool. Meta-analyses were performed using inverse variance weighted random-effects models. Statistical between-study heterogeneity was quantified by calculating Cochran's Q, τ2, and Higgins' I2 statistics. Sources of heterogeneity were analyzed and adjusted for within an intensive bias assessment in the form of meta-regression, outlier, influential, and subgroup analyses. A range of methods were used to test and adjust for publication bias.

RESULTS

Of 10,096 records that were originally identified by the search strategy, 45 were included in the meta-analyses. RA was inversely associated with both breast and uterine cancer occurrence, while PsO was associated with a higher breast cancer risk. Outlier-adjusted estimates confirmed these findings. Bias assessment revealed differences in geographic regions, particularly in RA patients, with higher estimates among Asian studies. An additional analysis revealed no association between psoriatic arthritis and breast cancer.

CONCLUSIONS

RA seems to reduce the risk of breast and uterine cancers, while PsO appears to increase breast cancer risk. Further large studies are required to investigate potential therapy-effects and detailed biological mechanisms.

Questionnaire survey on the prevention and development of cervical cancer in patients with systemic lupus erythematosus in Japan

OBJECTIVES

The aim is to evaluate the prevention and development of cervical cancer in systemic lupus erythematosus (SLE) patients in Japan and its background based on a questionnaire survey.

METHODS

The questionnaire was handed to 460 adult female SLE patients at 12 medical institutions. The participants were grouped by age, and data related to their human papillomavirus vaccination status, age at first coitus, cervical cancer screening, and diagnosis of cervical cancer were analysed.

RESULTS

A total of 320 responses were received. Patients aged 35-54 years included a higher proportion of patients whose age at first coitus was <20 years. This group also showed a higher rate of cervical cancer/dysplasia. Only nine patients had a human papillomavirus vaccination history. Adequate frequency of cervical cancer screening was slightly higher (52.1%) among SLE patients than in the Japanese general population. However, 23% of the patients had never undergone examination, primarily because of a feeling of troublesome. The incidence of cervical cancer was significantly higher among SLE patients. One reason for this may be associated with the use of immunosuppressants, although the difference was not significant.

CONCLUSIONS

SLE patients are at a higher risk of cervical cancer and dysplasia. Rheumatologists should proactively recommend vaccination and screening examinations for SLE female patients.

Study of alloferon, a novel immunomodulatory antimicrobial peptide (AMP), and its analogues

Antimicrobial peptides (AMPs) are widely distributed throughout the biosphere and represent a class of conserved peptide molecules with intrinsic antimicrobial properties. Their broad-spectrum antimicrobial activity and low risk to induce resistance have led to increased interest in AMPs as potential alternatives to traditional antibiotics. Among the AMPs, alloferon has been addressed due to its immunomodulatory properties that augment both innate and adaptive immune responses against various pathogens. Alloferon and its analogues have demonstrated pharmaceutical potential through their ability to enhance Natural Killer (NK) cell cytotoxicity and stimulate interferon (IFN) synthesis in both mouse and human models. Additionally, they have shown promise in augmenting antiviral and antitumor activities in mice. In this article, we provide a comprehensive review of the biological effects of alloferon and its analogues, incorporating our own research findings as well. These insights may contribute to a deeper understanding of the therapeutic potential of these novel AMPs.

Risk of Cervical Abnormalities for Women With Multiple Sclerosis Treated With Moderate-Efficacy and High-Efficacy Disease-Modifying Therapies

BACKGROUND AND OBJECTIVES

The impact of immunomodulatory therapies on the risk of cervical pre-cancer and invasive cancer development is important for the health and safety of women with multiple sclerosis (wwMS). We investigate the risk of cervical abnormalities in wwMS treated with disease-modifying therapies (DMTs).

METHODS

This is a multicenter cohort study with data collected from 1998 to 2019 in Victoria, Australia. Data linkage was performed using matching records from the MSBase Registry, the National Human Papillomavirus (HPV) Vaccination Program Register, and the Victorian Cervical Cytology Register. The primary outcome was the detection of any type of cervical abnormality as determined by cytology or histology. Survival methods were used to assess the time to cervical abnormality detection on cervical screening tests (CSTs). Crude and adjusted Cox proportional hazards models were used to determine time to and magnitude of association of DMTs with the risk of cervical abnormality. In a sensitivity analysis, we constructed standardized survival curves averaged over the same set of covariates to determine the commensurate population-average (marginal) causal effects.

RESULTS

We included 248 wwMS. The incidence of abnormal CSTs was lower (p < 0.001) for women not exposed to moderate-high-efficacy therapy (10.2 per 1,000 patient-years [95% confidence interval (CI) 5.5-14.9]), compared with those exposed (36.6 per 1,000 patient-years [95% CI 21.7-51.6]). Exposure to higher efficacy treatment was associated with a 3.79-fold increased hazard (95% CI 2.02-7.08, p < 0.001) of developing a cervical abnormality relative to those not exposed. When adjusted for vaccination status, smoking, hormonal contraceptive use, and socioeconomic status, the risk remained elevated at 3.79 (95% CI 1.99-7.21, p < 0.001). Marginal hazard ratios declined over time, ranging from 3.90 (95% CI 2.09-7.27) at 20 years of age to 2.06 (95% CI 1.14-3.73) at 70 years of age.

DISCUSSION

A greater than three-and-a-half-fold increased risk of cervical abnormalities was found after exposure to moderate-high-efficacy DMTs. This risk persisted despite adjusting for HPV vaccination status, hormonal contraception use, smoking, and socioeconomic status. If confirmed in future studies, we would advocate for wwMS exposed to moderate-high-efficacy DMTs to be treated in line with immune-deficient paradigm in cervical screening and HPV vaccination programs.

CLASSIFICATION OF EVIDENCE

This study provides Class III evidence that highly active MS therapy compared with less active therapy increases the risk of developing cervical abnormalities among women with MS.

The 2023 Impact of Inflammatory Bowel Disease in Canada: Cancer and IBD

Cancer is a major cause of morbidity and mortality among people with inflammatory bowel disease (IBD). Intestinal cancers may arise as a complication of IBD itself, while extra-intestinal cancers may arise due to some of the immunosuppressive therapies used to treat IBD. Colorectal cancer (CRC) and small bowel cancer risks remain elevated among persons with IBD as compared to age-and sex-matched members of the general population, and the lifetime risk of these cancers is strongly correlated to cumulative intestinal inflammatory burden. However, the cumulative risk of cancer, even among those with IBD is still low. Some studies suggest that IBD-CRC incidence has declined over the years, possibly owing to improved treatment standards and improved detection and management of early neoplastic lesions. Across studies of extra-intestinal cancers, there are generally higher incidences of melanoma, hepatobiliary cancer, and lung cancer and no higher incidences of breast cancer or prostate cancer, with equivocal risk of cervical cancer, among persons with IBD. While the relative risks of some extra-intestinal cancers are increased with treatment, the absolute risks of these cancers remain low and the decision to forego treatment in light of these risks should be carefully weighed against the increased risks of intestinal cancers and other disease-related complications with undertreated inflammatory disease. Quality improvement efforts should focus on optimized surveillance of cancers for which surveillance strategies exist (colorectal cancer, hepatobiliary cancer, cervical cancers, and skin cancers) and the development of cost-effective surveillance strategies for less common cancers associated with IBD.

Papillomaviruses and cancer: commonalities and differences in HPV carcinogenesis at different sites of the body

Human papillomavirus (HPV) is associated with 5% of all cancers globally at a range of body sites, including cervix, anus, penis, vagina, vulva, and oropharynx. These cancers claim > 400,000 lives annually. The persistent infection of HPV and the function of viral oncogenes are the primary causes of HPV-related cancers. However, only some HPV-infected persons or infected lesions will progress to cancer, and the burden of HPV-associated cancer varies widely according to gender and the part of the body infected. The dissimilarity in infection rates at different sites can explain only a small part of the differences observed. Much responsibility likely sits with contributions of specific epithelial cells and the cellular microenvironment at infected sites to the process of malignant transformation, both of which affect the regulation of viral gene expression and the viral life cycle. By understanding the biology of these epithelial sites, better diagnosis/treatment/management of HPV-associated cancer and/or pre-cancer lesions will be provided.

Extraintestinal Cancers in Inflammatory Bowel Disease: A Literature Review

BACKGROUND

Inflammatory bowel disease (IBD) is a group of chronic multifactorial inflammatory disorders including two major entities: Crohn's disease (CD) and ulcerative colitis (UC). Preliminary evidence suggests that patients with IBD may be at increased risk of developing intestinal and extraintestinal cancers (EICs). Actually, little is known about the association between IBD and EICs, and there is ever-growing concern regarding the safety of immunomodulators and biological therapy, which may represent a risk factor for carcinogenesis.

AIMS

The aim of this review is to summarize the evidence regarding the association between IBD and EICs, the safety of immunomodulators and biological therapy and the management of immunomodulators and biologic agents in IBD patients with prior or current EICs.

RESULTS

IBD patients have a higher risk of developing different forms of extraintestinal solid organ tumors and hematological malignancies. Immunomodulators and biological therapy may increase the risk of developing some types of EICs and may be consciously used in patients with IBD and current or prior history of malignancy.

CONCLUSIONS

Decisions regarding the use of immunomodulators or biological therapies should be made on an individual basis, considering a multidisciplinary approach involving oncologists.

Risk of uterine cervical cancer in inflammatory bowel disease: a systematic review and meta-analysis

BACKGROUND AND AIMS

There are limited data on the association between uterine cervical cancer (UCC) and inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC).

METHODS

This systematic review and meta-analysis assessed the risk of UCC in patients with IBD. We searched MEDLINE, Embase, Cochrane Library, Scopus, Web of Science, ClinicalTrials.gov, gray literature and conference proceedings for studies published before 21 January 2022. Two reviewers independently screened studies, extracted data and assessed quality using the Newcastle-Ottawa Scale. Subgroup analyses were based on IBD type, biologic era, immunosuppression status, study location and design, and publication status. Fifteen studies were included.

RESULTS

The pooled relative risk (RR) of UCC in IBD was 1.34 (95% confidence interval [CI], 1.07-1.69; I2 = 53.4%). In subgroup analyses, the pooled RRs of UCC in CD and UC were 1.18 (95% CI, 0.97-1.42) and 1.50 (95% CI, 1.01-12.21), respectively. The pooled RRs of UCC in pre-biologic and biologic eras were 1.36 (95% CI, 0.83-2.23) and 1.99 (95% CI, 1.03-3.86), respectively. The pooled RR of UCC in immunomodulator users was 2.18 (95% CI, 0.81-5.87). The pooled RRs of UCC in Asia, Europe and North America were 5.65 (95% CI, 2.65-12.07), 1.13 (95% CI, 0.96-1.34) and 1.38 (95% CI, 1.10-1.73), respectively.

CONCLUSIONS

The risk of UCC was significantly increased in IBD, particularly in UC but not in CD, suggesting that women with IBD should undergo regular UCC screening and consider vaccination.

Association between multiple sclerosis and cancer risk: An extensive review/meta and Mendelian randomization analyses

BACKGROUND

Observational investigations examining cancer risk among multiple sclerosis (MS) patients have produced contradictory findings. Herein, we performed an extensive review and meta-analysis to evaluate the correlation and causation between MS and cancer incidence.

METHODS

We systematically screened for published articles examining cancer incidences among MS patients within the Cochrane Library, PubMed, and Embase databases. Next, we employed STATA v.16.0 for data analysis. Following meta-analysis, we performed a two-sample Mendelian randomization (MR) analysis to uncover the underlying mechanism behind the MS-mediated regulation of certain cancers.

RESULTS

Overall, we selected 18 articles encompassing 14 individual cancers incidences and a total of 368,952 patients for meta-analysis. Based on our analysis, there was reduced pancreatic (ES = 0.68; 95% CI: 0.49-0.93; I 2 = 0%) and ovarian cancer (ES = 0.65; 95% CI: 0.53-0.80; I 2 = 86.7%) co-occurrences among MS patients. Meanwhile, the incidences of breast (ES = 1.10; 95% CI: 1.01-1.21; I 2 = 60.9%) and brain cancers (ES = 1.94; 95% CI: 1.12-3.37; I 2 = 56.1%) were elevated among the same population. However, MR analysis revealed the opposite relation between MS and breast cancer risk (OR = 0.94392; 95% CI: 0.91011-0.97900, P = 0.002). Moreover, it revealed strong incidence of lung cancer (OR = 1.0004; 95% CI: 1.0001-1.0083, P = 0.001) among MS patients, as evidenced by the inverse variance weighting estimator. Lastly, MR found that other forms of cancers were not significantly related to MS.

CONCLUSIONS

Using meta-analysis, we demonstrated that MS patients exhibited enhanced pancreatic and ovarian cancer risk, and diminished breast and brain cancer risk. However, using MR analysis, we discovered an inverse relation between MS and breast cancer risk, and additionally saw an uptick in lung cancer co-occurrence among MS patients.

The Optimal Management of Inflammatory Bowel Disease in Patients with Cancer

Patients with inflammatory bowel disease (IBD) have an increased risk of cancer secondary to chronic inflammation and long-term use of immunosuppressive therapy. With the aging IBD population, the prevalence of cancer in IBD patients is increasing. As a result, there is increasing concern about the impact of IBD therapy on cancer risk and survival, as well as the effects of cancer therapies on the disease course of IBD. Managing IBD in patients with current or previous cancer is challenging since clinical guidelines are based mainly on expert consensus. Evidence is rare and mainly available from registries or observational studies. In contrast, excluding patients with previous/or active cancer from clinical trials and short-term follow-up can lead to an underestimation of the cancer or cancer recurrence risk of approved medications. The present narrative review aims to summarize the current evidence and provide practical guidance on the management of IBD patients with cancer.

HPV and Cervical Cancer: A Review of Epidemiology and Screening Uptake in the UK

Cervical cancer is the fourth most common malignancy in females worldwide, and a leading cause of death in the United Kingdom (UK). The human papillomavirus (HPV) is the strongest risk factor for developing cervical intraepithelial neoplasia and cancer. Across the UK, the national HPV immunisation programme, introduced in 2008, has been successful in protecting against HPV-related infections. Furthermore, the National Health Service (NHS) implemented the cytology-based cervical cancer screening service to all females aged 25 to 64, which has observed a decline in cervical cancer incidence. In the UK, there has been an overall decline in age-appropriate coverage since April 2010. In 2019, the COVID-19 pandemic disrupted NHS cancer screening and immunisation programmes, leading to a 6.8% decreased uptake of cervical cancer screening from the previous year. Engagement with screening has also been associated with social deprivation. In England, incidence rates of cervical cancer were reported to be 65% higher in the most deprived areas compared to the least, with lifestyle factors such as cigarette consumption contributing to 21% of cervical cancer cases. In this article, we provide an update on the epidemiology of cervical cancer, and HPV pathogenesis and transmission, along with the current prevention programmes within the NHS.

Risk of cervical pre-cancer and cancer in women with multiple sclerosis exposed to high efficacy disease modifying therapies

There is a growing need to better understand the risk of malignancy in the multiple sclerosis (MS) population, particularly given the relatively recent and widespread introduction of immunomodulating disease modifying therapies (DMTs). Multiple sclerosis disproportionately affects women, and the risk of gynecological malignancies, specifically cervical pre-cancer and cancer, are of particular concern. The causal relationship between persistent human papillomavirus (HPV) infection and cervical cancer has been definitively established. To date, there is limited data on the effect of MS DMTs on the risk of persistent HPV infection and subsequent progression to cervical pre-cancer and cancer. This review evaluates the risk of cervical pre-cancer and cancer in women with MS, including the risk conferred by DMTs. We examine additional factors, specific to the MS population, that alter the risk of developing cervical cancer including participation in HPV vaccination and cervical screening programs.

Identification of Drug-Cancer Associations: A Nationwide Screening Study

The main tool in drug safety monitoring, spontaneous reporting of adverse effects, is unlikely to detect delayed adverse drug effects including cancer. Hypothesis-free screening studies based on administrative data could improve ongoing drug safety monitoring. Using Danish health registries, we conducted a series of case-control studies by identifying individuals with incident cancer in Denmark from 2001 to 2018, matching each case with 10 population controls on age, sex, and calendar time. ORs were estimated using conditional logistic regression accounting for matching factors, educational level, and selected comorbidities. A total of 13,577 drug-cancer associations were examined for individual drugs and 8,996 for drug classes. We reviewed 274 drug-cancer pairs where an association with high use and a cumulative dose-response pattern was present. We classified 65 associations as not readily attributable to bias of which 20 were established as carcinogens by the International Agency for Research on Cancer and the remaining 45 associations may warrant further study. The screening program identified drugs with known carcinogenic effects and highlighted a number of drugs that were not established as carcinogens and warrant further study. The effect estimates in this study should be interpreted cautiously and will need confirmation targeted epidemiologic and translational studies.

Significance

This study provides a screening tool for drug carcinogenicity aimed at hypothesis generation and explorative purposes. As such, the study may help to identify drugs with unknown carcinogenic effects and, ultimately, improve drug safety as part of the ongoing safety monitoring of drugs.

Health Care Maintenance in Patients with Crohn's Disease

Health care maintenance is critical for patients with inflammatory bowel disease (IBD), particularly for those receiving immunosuppressive medications. Vaccination recommendations for potentially preventable diseases, cancer prevention recommendations, and assessment of bone health and mood disorders are discussed in this article. Staying up to date with health care maintenance is of utmost importance, and all gastroenterologists caring for patients with IBD should be able to make recommendations regarding preventative care of these patients.

Hormone-Related Cancer and Autoimmune Diseases: A Complex Interplay to be Discovered

Neoplasic transformation is a continuous process that occurs in the body. Even before clinical signs, the immune system is capable of recognizing these aberrant cells and reacting to suppress them. However, transformed cells acquire the ability to evade innate and adaptive immune defenses through the secretion of molecules that inhibit immune effector functions, resulting in tumor progression. Hormones have the ability to modulate the immune system and are involved in the pathogenesis of autoimmune diseases, and cancer. Hormones can control both the innate and adaptive immune systems in men and women. For example androgens reduce immunity through modulating the production of pro-inflammatory and anti-inflammatory mediators. Women are more prone than men to suffer from autoimmune diseases such as systemic lupus erythematosus, psoriasis and others. This is linked to female hormones modulating the immune system. Patients with autoimmune diseases consistently have an increased risk of cancer, either as a result of underlying immune system dysregulation or as a side effect of pharmaceutical treatments. Epidemiological data on cancer incidence emphasize the link between the immune system and cancer. We outline and illustrate the occurrence of hormone-related cancer and its relationship to the immune system or autoimmune diseases in this review. It is obvious that some observations are contentious and require explanation of molecular mechanisms and validation. As a result, future research should clarify the molecular pathways involved, including any causal relationships, in order to eventually allocate information that will aid in the treatment of hormone-sensitive cancer and autoimmune illness.

The Cancer Risk Profile of Systemic Lupus Erythematosus Patients

ABSTRACT

Systemic lupus erythematosus (SLE) patients have a well-established increased risk for cancer. Research from the past 2 decades has identified the specific malignancies that afflict SLE patients at disproportionate rates. Systemic lupus erythematosus patients are at heightened risk for several hematologic malignancies as well as for certain solid tumors, including lung, thyroid, and hepatobiliary cancers. They are at decreased risk for several cancers as well, including prostate and melanoma. Improved understanding of the unique cancer risk profile of SLE patients has led some professional societies to recommend specialized cancer screening and prevention measures for these patients and has enabled clinicians to better serve the SLE patient population.

Prevalence and Distribution of HPV Genotypes in Immunosuppressed Patients in Lorraine Region

Background: The primary objective of this work was to assess the prevalence and distribution of HPV genotypes in immunosuppressed patients, and to compare them with the French Monsonego cohort. Secondary objectives were to evaluate whether the risk of HPV infection was correlated with HIV viral load, CD4 cell count in HIV-infected patients and the type, number of immunosuppressive therapies or type of pathology (transplant vs. autoimmune diseases) in patients undergoing long-term immunosuppressive therapy. Methods: An observational, monocentric and historical study was conducted including all immunosuppressed patients having received an HPV testing, in the Laboratory of Virology, Nancy Regional Teaching Hospital Center, between 2014 and 2020. Immunosuppressed patients were either HIV-infected or received long-term immunosuppressive therapy. Results: In our cohort, the prevalence of HPV infection (75.6% vs. 16.1% p < 0.05), the proportion of patients with high-risk HPV infection (48.9% vs. 15.1% p < 0.05) and with multiple HPV infection (41.1% vs. 5.7% p < 0.05) were significantly higher than in the Monsonego cohort. HPV 52 (13%), 53 (13%) and 16 (10%) were the most common in the immunosuppressed population, while it was HPV 16, 42 and 51 in the Monsonego cohort. Conclusions: This study supports that a particular attention must be given to all the immunosuppressed patients for the screening and care of HPV-related diseases because of major modifications of HPV epidemiology compared with the overall population.

Canadian Association of Gastroenterology Clinical Practice Guideline for Immunizations in Patients With Inflammatory Bowel Disease (IBD)-Part 2: Inactivated Vaccines

BACKGROUND AND AIMS

The effectiveness and safety of vaccinations can be altered by immunosuppressive therapies, and perhaps by inflammatory bowel disease (IBD) itself. These recommendations developed by the Canadian Association of Gastroenterology and endorsed by the American Gastroenterological Association, aim to provide guidance on immunizations in adult and pediatric patients with IBD. This publication focused on inactivated vaccines.

METHODS

Systematic reviews evaluating the efficacy, effectiveness, and safety of vaccines in patients with IBD, other immune-mediated inflammatory diseases, and the general population were performed. Critical outcomes included mortality, vaccine-preventable diseases, and serious adverse events. Immunogenicity was considered a surrogate outcome for vaccine efficacy. Certainty of evidence and strength of recommendations were rated according to the GRADE (Grading of Recommendation Assessment, Development, and Evaluation) approach. Key questions were developed through an iterative online platform, and voted on by a multidisciplinary group. Recommendations were formulated using the Evidence-to-Decision framework. Strong recommendation means that most patients should receive the recommended course of action, whereas a conditional recommendation means that different choices will be appropriate for different patients.

RESULTS

Consensus was reached on 15 of 20 questions. Recommendations address the following vaccines: Haemophilus influenzae type b, recombinant zoster, hepatitis B, influenza, pneumococcus, meningococcus, tetanus-diphtheria-pertussis, and human papillomavirus. Most of the recommendations for patients with IBD are congruent with the current Centers for Disease Control and Prevention and Canada's National Advisory Committee on Immunization recommendations for the general population, with the following exceptions. In patients with IBD, the panel suggested Haemophilus influenzae type b vaccine for patients older than 5 years of age, recombinant zoster vaccine for adults younger than 50 year of age, and hepatitis B vaccine for adults without a risk factor. Consensus was not reached, and recommendations were not made for 5 statements, due largely to lack of evidence, including double-dose hepatitis B vaccine, timing of influenza immunization in patients on biologics, pneumococcal and meningococcal vaccines in adult patients without risk factors, and human papillomavirus vaccine in patients aged 27-45 years.

CONCLUSIONS

Patients with IBD may be at increased risk of some vaccine-preventable diseases. Therefore, maintaining appropriate vaccination status in these patients is critical to optimize patient outcomes. In general, IBD is not a contraindication to the use of inactivated vaccines, but immunosuppressive therapy may reduce vaccine responses.

Risk of precancerous cervical lesions in women using a hormone-containing intrauterine device and other contraceptives: a register-based cohort study from Denmark

STUDY QUESTION

Is the risk of high-grade precancerous cervical lesions and/or is the risk of lesion progression increased in users of a hormone-containing intrauterine device (HIUD) compared with users of other contraceptive methods.

SUMMARY ANSWER

Women starting use of HIUD had the same subsequent risk of cervical intraepithelial neoplasia 3+ (CIN3+) as copper IUD (CIUD) users, and both groups tended to have lower risks than oral contraceptives (OC) users.

WHAT IS KNOWN ALREADY

HIUDs may cause inflammatory and immunosuppressive changes that may potentially affect the risk of persistent human papillomavirus infection and precancerous cervical lesions.

STUDY DESIGN, SIZE, DURATION

A Danish population-based cohort study was conducted using register data from 2008 to 2011 on 26–50-year-old users of HIUD (n = 60 551), CIUD (n = 30 303), or OC (n = 165 627).

PARTICIPANTS/MATERIALS, SETTING, METHODS

Within each user group, women were divided into two groups; normal cytology or abnormal diagnosis before start of contraceptive use (baseline). Follow-up histology and cytology diagnoses were registered during the 5 years after baseline. Adjusted relative risks (aRR) and 95% CI were calculated for precancerous cervical lesions in HIUD users compared with CIUD and OC users.

MAIN RESULTS AND THE ROLE OF CHANCE

Women with normal cytology at baseline: at follow-up HIUD users had the same risk of CIN3 or higher (3+) as CIUD users; aRR 1.08 (95% CI 0.94–1.22). For the HIUD and CIUD groups compared with OCs, the risks of CIN3+ were lower: aRR 0.63 (95% CI 0.57–0.69) and aRR 0.58 (95% CI 0.52–0.65), respectively. The same was observed for CIN2 risks: aRR 0.86 (95% CI 0.76–0.96) and aRR 0.68 (95% CI 0.58–0.79) for HIUD and CIUD groups, respectively. Women with abnormal diagnosis at baseline: a lower progression risk, except for CIN2+ at baseline, was observed in HIUD users compared with OC users. Similar progression risks were found in HIUD and CIUD users. There were no differences between the three contraceptive groups in persistence or regression of present lesions.

LIMITATIONS, REASONS FOR CAUTION

We adjusted for age, education, and region of residence as a proxy for socio-economic factors. Data on smoking and sexual behavior were not available thus we cannot exclude some differences between the three user groups.

WIDER IMPLICATIONS OF THE FINDINGS

These findings suggest that women may safely use HIUDs.

[Human papillomavirus and systemic lupus erythematosus]

Infection with human papillomavirus (HPV) is one of the most widespread sexually transmitted diseases and the main risk factor for cervical cancer. Underlying conditions, like immunosuppression, favour the persistence and the progression of cervical lesions to an aggressive form. Patients with autoimmune diseases, and particularly systemic lupus erythematosus (SLE), may be prone to HPV infection and cervical dysplasia. However, the risk factors for developing persistent HPV-related infection, dysplasia and cancer are not identified for patients with SLE. The existence of an increased risk of cervical cancer compared to the general population remains debated. Thus, HPV vaccine is recommended for SLE patients as well as for the general population. Vaccine coverage of SLE patients is not known in France. Adolescents with chronic health condition seem to be insufficiently vaccinated regarding their vulnerability to infectious diseases. Strategies are required to decrease HPV vaccination barriers.

Factors Associated With 30-Day Rehospitalization and Mortality in Older Patients After a Pneumonia Admission

OBJECTIVES

Short-term rehospitalization and mortality are common events in older patients after a pneumonia admission, yet little knowledge exists on how to identify the patients at risk of these events. This knowledge is needed to ensure that health care attention is given to those with the highest needs. We therefore aimed to identify factors of importance for short-term rehospitalization and mortality in older patients after admission for pneumonia.

DESIGN

Population-based cohort study.

SETTING

The Danish nationwide registries.

PARTICIPANTS

In total, 246,245 individuals aged 65-99 years who experienced 298,564 admissions for pneumonia from 2000 to 2016.

METHODS

The explored factors in patients were demographic characteristics, health-seeking behavior, comorbidity, and medication use. A Cox proportional hazards model was used to calculate hazard ratios (HRs) for 30-day rehospitalization and 30-day mortality with 95% confidence intervals (CIs).

RESULTS

Of the 298,564 admissions for pneumonia, 23.0% were rehospitalized and 8.1% died within 30 days of follow-up. Most of the investigated factors were significantly associated with these 2 outcomes. The HRs for rehospitalization ranged from 0.80 (95% CI 0.75-0.85) for old vs young age to 4.29 (95% CI 4.05-4.54) for many vs no prior admissions, whereas the HRs for mortality ranged from 0.87 (95% CI 0.83-0.91) for any vs no practical home care to 5.47 (95% CI 5.08-5.88) for old vs young age. Number of comorbidities, medications, and prior contacts to the health care system were associated with higher risk of both rehospitalization and mortality in a dose-response manner.

CONCLUSIONS AND IMPLICATIONS

This study identified several potential factors of importance for short-term rehospitalization and mortality in older patients discharged after pneumonia. This knowledge can help physicians identify the patients with the highest need of care after admission for pneumonia, thus enabling efficient discharge planning and high-quality provision of care in primary care settings.

Increased risk of cervical dysplasia in females with autoimmune conditions-Results from an Australia database linkage study

Background

Autoimmune conditions (AICs) and/or their treatment may alter risk of human papilloma virus (HPV) infection and females with AICs are therefore at an increased risk of cervical dysplasia. However, inclusion of these at-risk populations in cervical cancer screening and HPV-vaccination guidelines, are mostly lacking. This study aimed to determine the prevalence of cervical dysplasia in a wide range of AICs and compare that to HIV and immunocompetent controls to support the optimisation of cervical cancer preventive health measures.

Methods

Data linkage was used to match cervical screening episodes to emergency department records of females with AICs or HIV to immunocompetent controls over a 14-year period. The primary outcome was histologically confirmed high-grade cervical disease. Results, measured as rates by cytology and histology classification per 1,000 females screened, were analysed per disease group, and intergroup comparisons were performed.

Results

Females with inflammatory bowel disease (2,683), psoriatic and enteropathic arthropathies (1,848), multiple sclerosis (MS) (1,426), rheumatoid arthritis (1,246), systemic lupus erythematosus and/or mixed connective tissue disease (SLE/MCTD) (702), HIV (44), and 985,383 immunocompetent controls were included. SLE/MCTD and HIV groups had greater rates of high-grade histological and cytological abnormalities compared to controls. Increased rates of low-grade cytological abnormalities were detected in all females with AICs, with the exception of the MS group.

Conclusions

Females with SLE/MCTD or HIV have increased rates of high-grade cervical abnormalities. The increased low-grade dysplasia rate seen in most females with AICs is consistent with increased HPV infection. These findings support expansion of cervical cancer preventative programs to include these at-risk females.

Predicting, Preventing, and Managing Treatment-Related Complications in Patients With Inflammatory Bowel Diseases

Risk of complications from specific classes of drugs for inflammatory bowel diseases (IBDs) can be kept low by respecting contraindications. Patients with IBD frequently develop serious infections resulting from the disease itself or its treatment. At the time of diagnosis, patients' vaccination calendars should be updated according to IBD guidelines-live vaccines should be postponed for patients receiving immunosuppressive drugs. Opportunistic infections should be detected and the vaccine against pneumococcus should be given before patients begin immunosuppressive therapy. Thiopurines promote serious viral infections in particular, whereas tumor necrosis factor (TNF) antagonists promote all types of serious and opportunistic infections. Severe forms of varicella can be prevented by vaccinating seronegative patients against varicella zoster virus. Detection and treatment of latent tuberculosis is mandatory before starting anti-TNF therapy and other new IBD drugs. Tofacitinib promotes herpes zoster infection in a dose- and age-dependent manner. Physicians should consider giving patients live vaccines against herpes zoster before they begin immunosuppressive therapy or a recombinant vaccine, when available, at any time point during treatment. The risk of thiopurine-induced lymphomas can be lowered by limiting the use of thiopurines in patients who are seronegative for Epstein-Barr virus (especially young men) and in older men. The risk of lymphoma related to monotherapy with anti-TNF agents is still unclear. There are no robust data on the carcinogenic effects of recently developed IBD drugs. For patients with previous cancer at substantial risk of recurrence, physicians should try to implement a pause in the use of immunosuppressive therapy (except in patients with severe disease and no therapeutic alternative) and prioritize use of IBD drugs with the lowest carcinogenic effects. Finally, sun protection and skin surveillance from the time of diagnosis are recommended.

Mycophenolate mofetil, azathioprine and tacrolimus: mechanisms in rheumatology

The introduction of biologic DMARDs into rheumatology has resulted in a substantial reduction of the burden of many rheumatic diseases. In the slipstream of the success achieved with these biologic DMARDs, some conventional immunosuppressive drugs have also found use in new indications. Notably, mycophenolate mofetil, azathioprine and tacrolimus have made their way from solid organ transplantation drugs to become useful assets in rheumatology practice. Mycophenolate mofetil and azathioprine inhibit the purine pathway and subsequently diminish cell proliferation. Both drugs have a pivotal role in the treatment of various rheumatic diseases, including lupus nephritis. Tacrolimus inhibits lymphocyte activation by inhibiting the calcineurin pathway. Mycophenolate mofetil and tacrolimus are, among other indications, increasingly being recognized as useful drugs in the treatment of interstitial lung disease in systemic rheumatic diseases and skin fibrosis in systemic sclerosis. A broad array of trials with mycophenolate mofetil, azathioprine and/or tacrolimus are ongoing within the field of rheumatology that might provide further novel avenues for the use of these drugs. In this Review, we discuss the historical perspective, pharmacodynamics, clinical indications and novel avenues for mycophenolate mofetil, azathioprine and tacrolimus in rheumatology.

Genital Dysplasia and Immunosuppression: Why Organ-Specific Therapy Is Important

BACKGROUND

Young patients with Crohn's disease (CD) show a high prevalence of human papillomavirus (HPV) which is the main cause of high-grade squamous intraepithelial lesions (HSIL). A major complication for patients undergoing immunocompromising therapy is the development of genital dysplasia.

METHODS

We report the case of a 32-year-old patient with recurrent genital dysplasia under long-term therapy for CD with a focus on different drug-related, immunosuppressive mechanisms.

RESULTS

Gynecological examination and biopsy revealed high-grade vulvar intraepithelial neoplasia (VIN) positive for HPV 16 treated with laser vaporization. Due to the combination of HPV positivity, intraoperative multilocularity, and CD, follow-up examinations were performed every 6 months. One year later, the patient showed a VIN at a new location and additionally, a cervical intraepithelial neoplasia (CIN), which were surgically treated. Catch-up HPV vaccination was applied accessorily. After the switch from a TNF-α blocker to vedolizumab, which acts as a gut-selective anti-integrin, the subsequent PAP smear, vulvoscopy, and colposcopy showed no more evidence of dysplasia.

CONCLUSIONS

This case report highlights that gut-selective immunosuppression with vedolizumab might be favorable in young HPV-positive patients due to a good side effect profile. Regular screening and HPV vaccination are a mainstay of dysplasia prevention and control. The risk for HPV-associated dysplasia in immunosuppressed patients is highly dependent on the choice of immunosuppressive therapy.

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.

Sexual aspects of liver transplant candidates and recipients: evidence available in the literature1

OBJECTIVE

to analyze the evidence available in the literature on the alterations in the sexuality of candidates and recipients of liver transplantation.

METHOD

integrative review of the literature with search for primary studies in the databases MEDLINE (via PUBMED), CINAHL e LILACS, published in English, Portuguese and Spanish.

RESULTS

the 16 primary studies included were grouped into three categories: 1) female sexuality (n=5), 2) male sexuality (n=5) and 3) male and female sexuality (n=6). In category 1, the subjects investigated were contraception, pregnancy, sexual dysfunction, presence of gynecological symptoms and sexually transmitted infections. In category 2, the main focus of the studies was erectile dysfunction, sexual desire and satisfaction, and consequences of the immunosuppressive regimen with mycophenolic acid in men. In category 3, the evaluation of sexual function was the main topic.

CONCLUSION

the scientific evidence generated provides support to encourage health professionals to incorporate the topic of sexuality in the routine of care. Knowledge gaps were identified and new studies should be conducted in order to implement interventions to prevent, minimize and/or control changes related to the patient's sexuality.

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.

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.

Cervical neoplasia in systemic lupus erythematosus: a nationwide study

Objective

The aim was to examine the risk of cervical neoplasia in women with SLE, overall and with respect to treatment, compared with women from the general population.

Methods

By linking national Swedish registers, we assembled a cohort including women with SLE (n = 4976) and matched general population comparators (n = 29 703). Two subcohorts of treated SLE patients were defined on the basis of treatment with antimalarials (n = 1942) and other immunosuppressants (AZA, CYC, ciclosporin, MTX, MMF or rituximab; n = 2175). The main outcome was defined as a first cervical neoplasia (dysplasia or cancer) during follow-up. Secondary outcomes were first cervical intraepithelial neoplasia (CIN) 1; first CIN grades 2-3; and first invasive cervical cancer during follow-up (2006-12). Cox regression models estimated relative risks adjusted for age, level of education, health-care utilization, number of children, marital status, family history of cervical cancer and prior cervical screening.

Results

Based on 121 events of cervical neoplasia during 23 136 person-years among SLE patients, there was an increased risk of any cervical neoplasia compared with the general population [hazard ratio (HR) = 2.12 (95% CI: 1.65, 2.71)]. The risk of CIN 1 [HR = 2.33 (95% CI: 1.58, 3.44)], CIN 2-3 [HR = 1.95 (95% CI: 1.43, 2.65)], but not invasive cervical cancer [HR = 1.64 (95% CI: 0.54, 5.02)], was increased in women with SLE. The subcohort treated with other immunosuppressants was at highest risk of cervical neoplasia.

Conclusion

SLE is a risk factor for cervical neoplasia, in particular for pre-malignant cervical lesions. Among patients with SLE, the risk is higher among those treated with immunosuppresants compared with those treated with antimalarials.

A review on SLE and malignancy

Systemic lupus erythematosus (SLE) is a chronic, systemic autoimmune disease characterized by autoantibody production, complement activation, and immune complex deposition. It predominantly affects young and middle-aged women. While improvements in the diagnosis and treatment of SLE have altered prognosis, morbidity and mortality rates remain higher than the general population. In addition to renal injury, cardiovascular disease, and infection, malignancy is known to be a significant cause of death in this population. There is increasing evidence to suggest that patients with SLE have a slightly higher overall risk of malignancy. The risk of malignancy in SLE is of considerable interest because the immune and genetic pathways underlying the pathogenesis of SLE and the immunosuppressant drugs (ISDs) used in its management may mediate this altered risk. Our current understanding of these and other risk factors and the implications for treating SLE and screening for malignancy is still evolving. This review summarizes the association between SLE and malignancy. The first section discusses the risk of overall and site-specific malignancies in both adult- and pediatric-onset SLE. Next, we evaluate the risk factors and possible mechanisms underlying the link between malignancy and SLE, including the use of ISDs, presence of certain SLE-related autoantibodies, chronic immune dysregulation, environmental factors, and shared genetic susceptibility. Finally, we review guidelines regarding cancer screening and vaccination for human papilloma virus.

Thiopurine use associated with reduced B and natural killer cells in inflammatory bowel disease

AIM

To identify which blood and mucosal lymphocyte populations are specifically depleted by thiopurine use in vivo.

METHODS

The thiopurines azathioprine and 6-mercaptopurine have been a mainstay of inflammatory bowel disease (IBD) therapy for decades, but their mechanism of action in vivo remains obscure. Although thiopurines are lymphotoxic at high doses, and have been reported to cause T cell apoptosis in vitro, their ability to control IBD at lower doses suggests that they may selectively deplete particular lymphocyte populations. Blood cells from 19 IBD patients on a thiopurine, 19 IBD patients not on a thiopurine, and 38 matched healthy control subjects were analyzed by multiple multi-color flow cytometry panels to quantify the immune cell subsets contained therein, both as a percent of cells, and as an absolute cell count. Similar analyses were performed on colon biopsies from 17 IBD patients on a thiopurine, 17 IBD patients not on a thiopurine, and 49 healthy screening colonoscopy recipients.

RESULTS

Complete blood counts revealed lower lymphocyte, but not monocyte or granulocyte, counts in IBD patients who were taking thiopurines at the time of sampling. This reduction was restricted to CD3-negative lymphocytes, wherein both natural killer (NK) and B cells were significantly reduced among thiopurine recipients. Among CD19+ B cells, the transitional B cells were particularly depleted, being nearly absent in both blood and colon biopsies of thiopurine recipients. No differences were associated with thiopurine use in CD8+ T cells, mucosa-associated invariant T (MAIT) cells, invariant natural killer T (iNKT) cells, gamma/delta T cells, Th1, Th17, regulatory T cells (Tregs) or naïve CD4+ T cells. However, patients with IBD had significantly more circulating FOXP3+, Helios+ Tregs and fewer iNKT and MAIT cells than healthy controls.

CONCLUSION

Thiopurine use is associated with reduced B and NK cell, but not T cell, subpopulations in the blood of IBD patients.

Experts Opinion on the Practical Use of Azathioprine and 6-Mercaptopurine in Inflammatory Bowel Disease

The relevance of azathioprine and 6-mercaptopurine therapy in inflammatory bowel disease, Crohn's disease, and ulcerative colitis, has been challenged in recent publications. In this article, a panel of experts gives advice, based on the relevant literature, on indications and practical use of azathioprine/6-mercaptopurine, prevention, and management of drug adverse reactions and special situations such as vaccination, pregnancy, and lactation.

Risk of high-grade cervical dysplasia and cervical cancer in women with systemic lupus erythematosus receiving immunosuppressive drugs

Objective Prior studies suggest an increased risk of cervical cancer among women with systemic lupus erythematosus. However, the relationship with immunosuppressive drugs is not well studied in US nationwide cohorts. We compared the risk of high-grade cervical dysplasia and cervical cancer among women with systemic lupus erythematosus who started immunosuppressive drugs versus hydroxychloroquine. Methods We identified systemic lupus erythematosus patients initiating immunosuppressive drugs or hydroxychloroquine using claims data from two US commercial health plans and Medicaid (2000-2012). We used a validated claims-based algorithm to identify high-grade cervical dysplasia or cervical cancer. To account for potential confounders, including demographic factors, comorbidities, medication use, HPV vaccination status, and health care utilization, immunosuppressive drugs and hydroxychloroquine initiators were 1:1 matched on the propensity score. We used inverse variance-weighted, fixed effect models to pool hazard ratios from the propensity score-matched Medicaid and commercial cohorts. Results We included 2451 matched pairs of immunosuppressive drugs and hydroxychloroquine new users in the commercial cohort and 7690 matched pairs in Medicaid. In the commercial cohort, there were 14 cases of cervical dysplasia or cervical cancer among immunosuppressive drugs users and five cases among hydroxychloroquine users (hazard ratio 2.47, 95% CI 0.89-6.85, hydroxychloroquine = ref). In Medicaid, there were 46 cases among immunosuppressive drugs users and 29 cases in hydroxychloroquine users (hazard ratio 1.24, 95% CI 0.78-1.98, hydroxychloroquine = ref). The pooled hazard ratio of immunosuppressive drugs was 1.40 (95% CI 0.92-2.12). Conclusion Among women with systemic lupus erythematosus, immunosuppressive drugs may be associated with a greater, albeit not statistically significant, risk of high-grade cervical dysplasia and cervical cancer compared to patients receiving hydroxychloroquine alone.
