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.

Association Between Herpes Simplex Virus II Infection and Rheumatoid Arthritis in US Adults: A Population-Based Propensity Score-Matching Study

BACKGROUND/OBJECTIVE

The potential correlation between herpes simplex virus (HSV) and human papillomavirus (HPV) infections and rheumatoid arthritis (RA) has not been definitively established. Further research is needed to determine the relationship between the development of RA and the presence of these viral infections.

METHODS

A case-control study was conducted with data from the National Health and Nutrition Examination Survey between 2009 and 2014. Our analysis examined the association between HSV I, HSV II, HPV oral polymerase chain reaction (PCR), HPV vaginal PCR, and RA. We identified adults aged 20 to 49 years with a primary diagnosis of RA using the National Health and Nutrition Examination Survey database codes (MCQ191 = 1 [years 2009-2010]; MCQ195 = 2 [years 2011-2014]) and excluded patients with incomplete data on key variables and primary outcomes.

RESULTS

The study included 8620 patients, with 150 patients diagnosed with RA and 1500 patients without RA. Patients with RA had a significantly higher prevalence of HSV II infection compared with those without RA (36.34% vs. 24.72%, p = 0.015) after propensity score matching. No significant differences were observed for HSV I, HPV oral PCR, and HPV vaginal PCR between the 2 groups. Patients with RA were older; were more likely to be female, obese, and non-Hispanic White; and had a higher prevalence of comorbidities than those without RA.

CONCLUSIONS

This population-based propensity score-matching study provides evidence of an association between HSV II infection and RA in US adults. Further research is needed to fully elucidate the relationship between viral infections and RA, with the aim of developing effective risk reduction strategies and innovative treatments for RA.

Associations between immune-mediated diseases (IMDs) and the risk of HPV-associated diseases: a UK Biobank cohort analysis

OBJECTIVES

To systematically assess the associations between various immune-mediated diseases (IMDs) and human papillomavirus (HPV)-associated diseases.

DESIGN

Retrospective cohort study.

SETTING

UK Biobank.

PARTICIPANTS

A total of 500 371 subjects aged 40-69 years were eligible for the analysis, after excluding those with prevalent HPV-associated diseases at baseline and those who had withdrawn their informed consent or lacked information on sex.

EXPOSURE

Eighty IMDs (involving allergic/atopic diseases, autoimmune diseases, immunodeficiency diseases, etc) were identified in the UK Biobank.

PRIMARY AND SECONDARY OUTCOME MEASURES

The main outcome was the incidence of HPV-associated diseases (including warts and malignancies of the cervix, oropharynx, anus, penis, vulva and vagina). Cox proportional hazards model was used to estimate HRs and 95% CIs with particular adjustment for sexual behaviours. We also conducted subgroup analyses based on benign and malignant status, and anatomical sites of HPV-associated diseases, respectively.

RESULTS

During a median of 12.0 years of follow-up, 2244 cases out of 500 371 subjects developed HPV-associated diseases. Overall, participants with IMDs had a higher risk of HPV-associated diseases than their controls after adjustment for sexual behaviours and other potential confounders (female: HR=1.90, 95% CI=1.66 to 2.17, p<0.001; male: HR=1.66, 95% CI=1.41 to 1.97, p<0.001). Additionally, eight individual IMDs in women (eg, asthma: HR=1.76, 95% CI=1.47 to 2.11, p<0.001) and three in men (eg, chronic nephritic syndrome: HR=6.05, 95% CI=3.32 to 11.04, p<0.001) were associated with increased risk of HPV-associated diseases. Subgroup analyses revealed significant IMD differences between benign and malignant subgroups as well as between oropharyngeal and anogenital subgroups.

CONCLUSION

In this large retrospective cohort study, IMDs were significantly associated with an elevated risk of HPV-associated diseases. Besides, gender-specific and region-specific associations were also observed between individual IMDs and HPV-associated diseases.

Conventional and Biologic Disease-Modifying Antirheumatic Drugs Are Not Associated With Increase in or Progression of Cervical Neoplasia Among Patients With Spondyloarthritis

OBJECTIVES

Using a centralized electronic database, we investigated the risk of cervical neoplasia (CN) and progression of cervical intraepithelial neoplasia (CIN) among patients with spondyloarthritis (SpA) receiving disease-modifying antirheumatic drugs (DMARDs).

METHOD

A total of 951 patients with SpA were reviewed. Incidence and progression of CN and clinical data including age, ethnicity, smoking and drinking status, dates of first and last follow-up, history of psoriasis, inflammatory bowel disease, medications used, mean dose and duration of medications, and comorbidities were reviewed. Cox regression models were used to evaluate the individual risk of DMARDs with CN and the risk of CIN progression.

RESULTS

During a mean follow-up duration of 9.2 ± 5.9 years, 34 patients had developed CN, which translates to an incidence for development of CN in patients with SpA of 3.9 per 1000 patient-years. Univariate Cox regression analyses showed no differences in clinical characteristics (psoriasis hazards ratio [HR] = 0.92, p = 0.82; inflammatory bowel disease HR = 0.05, p = 0.61; diabetes mellitus HR = 2.82, p = 0.21; chronic kidney disease HR = 0.39, p = 0.35) and medications exposure (sulfasalazine HR = 0.49, p = 0.30; methotrexate HR = 0.52, p = 0.11; leflunomide HR = 0.52, p = 0.37; adalimumab HR = 0.83, p = 0.80; certolizumab HR = 0.05, p = 0.74; etanercept HR = 0.40, p = 0.36; golimumab HR = 0.05, p = 0.32; infliximab HR = 0.05, p = 0.39; secukinumab HR = 1.00, p = 1.00; ustekinumab HR = 0.05, p = 0.78) between patients who had and had not develop CN during the study period. Progression of CIN was independently associated with higher grades of CIN lesion (HR = 6.20; p = 0.05).

CONCLUSIONS

There was low risk of development and progression of CN in patients with SpA on conventional or biologic DMARD therapy.

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.

Cervical Cancer Screening in Women with Systemic Lupus Erythematosus

OBJECTIVE

To determine rates of cervical cancer screening and associated abnormal results in women with systemic lupus erythematosus (SLE).

METHODS

We identified women with an initial diagnosis of SLE in the MarketScan Commercial Claims and Encounters Database from 2001 to 2014. Cervical cancer screening rates and associated diagnostic claims within 3 years of initial claim were determined. Multivariable logistic regression was performed to evaluate the association of screening with lupus treatment. A matched logistic regression analysis was conducted to compare screening rates to those in age-matched women without connective tissue disease.

RESULTS

We included 4,316 women with SLE. Screening rates were higher in SLE women than in general controls (73.4% vs. 58.5%, p < 0.001). Factors associated with decreased screening included: recent time (odds ratio [OR] 0.70, 95% CI 0.55 - 0.89) (2012-2014 compared to 2001-2005); age ≥61 years (OR 0.27, 95% CI 0.18 - 0.39); comorbidity score of ≥2 (OR 0.71, 95% CI 0.6 - 0.83); corticosteroid use (OR 0.77, 95% CI 0.61 - 0.97); and use of immunosuppressants (OR 0.80, 95% CI 0.69 to 0.94). Abnormal pathology claims were more common in women with SLE than in general controls (12.3% vs. 9.8%, P < 0.001).

CONCLUSIONS

Though higher than the general cohort, over 25% of the patients with SLE were not screened and screening rates seem to be decreasing over time. Patients with SLE are at higher risk of abnormal cervical screening test results than controls, supporting the need for regular screening.

The Influence of Systemic Inflammation on Treatment Response and Survival in Anal Squamous Cell Cancer

AIMS

The incidence of anal squamous cell cancer (SCCA) is rising. Although chemoradiotherapy (CRT) provides a chance of cure, a proportion of patients have an incomplete response or develop recurrence. This study assessed the value of inflammation-based prognostic indicators, including the modified Glasgow Prognostic Score (mGPS) and neutrophil:lymphocyte ratio (NLR), in patients with SCCA treated by CRT with curative intent.

MATERIAL AND METHODS

Patients with histologically confirmed SCCA were identified from pathology records. Medical records were retrospectively reviewed and clinical, pathological and treatment characteristics were abstracted. The mGPS (0 = normal C-reactive protein [CRP] and albumin, 1 = CRP >10 mg/l and 2 = CRP >10 mg/l and albumin <35 mg/l) and NLR were calculated from routine blood tests obtained prior to CRT.

RESULTS

In total, 118 patients underwent CRT for SCCA between December 2007 and February 2018. Of these, 99 patients had appropriate pretreatment blood results available. Systemic inflammation as indicated by NLR >3 and mGPS >0 was present in 41% and 39% of patients, respectively. Most patients had T2 or larger tumours (n = 85, 86%) without nodal involvement (n = 64, 65%). An elevated mGPS was associated with more advanced T-stage (56% versus 35%, P = 0.036). NLR >5 was associated with nodal positivity (56% versus 31%, P = 0.047). On multivariate analysis, more advanced T-stage (odds ratio 7.49, 95% confidence interval 1.51-37.20, P = 0.014) and a raised mGPS (odds ratio 5.13, 95% confidence interval 1.25-21.14, P = 0.024) were independently related to incomplete CRT response. An elevated mGPS was prognostic of inferior survival (hazard ratio 3.09, 95% confidence interval 1.47-6.50, P = 0.003) and cancer-specific survival (hazard ratio 4.32, 95% confidence interval 1.54-12.15, P = 0.006), independent of TNM stage.

CONCLUSION

Systemic inflammation, as measured by the mGPS, is associated with an incomplete CRT response and is independently prognostic of inferior survival in patients with SCCA. The mGPS may offer a simple marker of inferior outcome that could be used to identify high-risk patients.

Risk of ankylosing spondylitis following human papillomavirus infection: A nationwide, population-based, cohort study

OBJECTIVE

To assess the incidence rate and risk of ankylosing spondylitis (AS) in patients with previous human papillomavirus (HPV) infection compared with those without HPV infection.

METHODS

All patients with HPV infection (n = 66,314) in the NHIRD (2003-2013) were individually matched with up to four control subjects without HPV infection by age and sex (n = 265,256). All of the patients were tracked until an AS event was noted. Chi-square test was used to analyze the distribution of sociodemographic characteristics in the HPV cohort and non-HPV cohort. Cox proportional hazards regression was used to calculate the HRs for the development of AS, adjusting for age, sex, urbanization, length of hospital stay, medications, and comorbidities adjustment. The Kaplan-Meier method was used to plot the cumulative incidence curves.

RESULTS

The HPV cohort had a 1.329 (95% C.I. = 1.138-1.552) times higher risk of AS than that of the non-HPV cohort after adjusting for sex, age, urbanization, length of hospital stay, comorbidities, and medications. Additionally, we applied propensity score weighting to reconfirm the accuracy of our analysis, and the results showed a 1.348 (95% C.I. = 1.153-1.575) times greater risk of AS in the HPV cohort compared with the non-HPV cohort. The cumulative incidence curves plotted by the Kaplan-Meier method revealed that after 120 follow-up months, the HPV cohort displayed a higher cumulative incidence of AS than that of the non-HPV cohort. (Log-rank test p < 0.0001).

CONCLUSIONS

Patients with HPV infection had a higher risk of developing AS compared with non-HPV patients.

Lower genital tract infections in young female juvenile idiopathic arthritis patients

BACKGROUND

To evaluate human papillomavirus (HPV), Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in juvenile idiopathic arthritis (JIA) patients.

METHODS

After exclusion, 33 female adolescent and young JIA patients (ILAR criteria) and 28 healthy controls were selected for this study. Demographic data, gynecological, sexual function, cervical cytology and histological abnormalities were evaluated. JIA clinical/laboratorial parameters and treatment were also assessed. HPV-DNA, CT-DNA and NG-DNA testing in cervical specimens were performed by Hybrid Capture 2 assays.

RESULTS

The mean current age was similar in JIA patients and controls (23.3 ± 6.24 vs. 26.1 ± 6.03 years, p = 0.09). The frequencies of sexual intercourse (76% vs. 89%, p = 0.201) and abnormal cervical cytology (24% vs. 11%, p = 0.201) were similar in JIA compared to controls. The higher frequency of HPV infection in JIA patients than controls (30% vs. 11%, p = 0.155) did not reach statistical significance. CT (0% vs. 7%, p = 0.207) and NG infections (0% vs. 4%, p = 0.459) were also alike in both groups. Further evaluation of JIA patients with abnormal and normal cervical cytology showed that the former group had a higher frequency of HPV infection (87% vs. 12%, p = 0.0002) with a low frequency of HPV vaccination (0% vs. 8%, p = 1.0). No differences were evidenced between these two JIA groups regarding demographic data, sexual function and clinical/laboratorial parameters. The frequencies of methotrexate (p = 0.206) and biological agent use (p = 0.238) were similar in both JIA groups.

CONCLUSIONS

To our knowledge, this was the first study to assess lower genital infections in JIA patients allowing the identification of HPV as main cause of cervical dysplasia. Methotrexate and biological agents do not seem to increase risk of lower genital tract infections in JIA patients.

Incidence and prevalence of vaccine preventable infections in adult patients with autoimmune inflammatory rheumatic diseases (AIIRD): a systemic literature review informing the 2019 update of the EULAR recommendations for vaccination in adult patients with AIIRD

Objectives

The aims of this study were to update the evidence on the incidence and prevalence rates of vaccine preventable infections (VPI) in patients with autoimmune inflammatory rheumatic diseases (AIIRD) and compare the data to the general population when available.

Methods

A literature search was performed using Medline, Embase and Cochrane library (October 2009 to August 2018). The primary outcome was the incidence or prevalence of VPI in the adult AIIRD population. Meta-analysis was performed when appropriate.

Results

Sixty-three publications out of 3876 identified records met the inclusion criteria: influenza (n=4), pneumococcal disease (n=7), hepatitis B (n=10), herpes zoster (HZ) (n=29), human papillomavirus (HPV) infection (n=13). An increased incidence of influenza and pneumococcal disease was reported in patients with AIIRD. HZ infection-pooled incidence rate ratio (IRR) was 2.9 (95% CI 2.4 to 3.3) in patients with AIIRD versus general population. Among AIIRD, inflammatory myositis conferred the highest incidence rate (IR) of HZ (pooled IRR 5.1, 95% CI 4.3 to 5.9), followed by systemic lupus erythematosus (SLE) (pooled IRR 4.0, 95% CI 2.3 to 5.7) and rheumatoid arthritis (pooled IRR 2.3, 95% CI 2.1 to 2.6). HPV infection-pooled prevalence ratio was 1.6, 95% CI 0.7 to 3.4 versus general population, based on studies mainly conducted in the SLE population in Latin America and Asia. Pooled prevalence of hepatitis B surface antigen and hepatitis B core antibody in patients with AIIRD was similar to the general population, 3%, 95% CI 1% to 5% and 15%, 95% CI 7% to 26%, respectively.

Conclusion

Current evidence shows an increased risk of VPI in patients with AIIRD, emphasising that prevention of infections is essential in these patients.

High-risk human papilloma virus infection and cervical neoplasm in female inflammatory bowel disease patients: a cross-sectional study

Background and aim

This cross-sectional study investigated the prevalence and risk factors of high-risk human papilloma virus (HPV) infection, especially types 16 and 18, and cervical neoplasia in female Inflammatory bowel disease (IBD) patients.

Methods

From July 2014 to January 2017, sexually active, female, Chinese IBD patients (21–60 years) and age-matched controls underwent cervical ThinPrep cytology testing (TCT) and high-risk HPV-DNA detection, and completed questionnaires about awareness of cervical cancer and HPV. Cervical dysplasia was categorized as cervical intraepithelial neoplasia (CIN) 1, 2 and 3.

Results

Of 124 IBD patients (30 ulcerative colitis and 94 Crohn’s disease), 17 (13.7%) had high-risk HPV among whom 9 (7.3%) had HPV 16/18 infection and 4 (3.2%) had cervical CIN (3 CIN 3, 1 CIN 1) by pathology. Among 372 controls, 33 (8.9%) had high-risk HPV and only 1 (0.3%) had HPV 16 infection. Cervical TCT detected atypical squamous cells of unknown significance in one control; no control had CIN. The HPV 16/18 infection rate and CIN prevalence were significantly higher in IBD patients than controls (both P < 0.001). The HPV-infection rate was higher in patients administered methotrexate [P = 0.005, odds ratio (95% confidence interval) 4.76 (1.471–15.402)] or more than two immunosuppressants [P = 0.013, odds ratio (95% confidence interval) 3.64 (1.255–10.562)]. Thiopurine, steroid, infliximab and disease behavior/location were not associated with HPV infection. Only 29.3% of patients had undergone cervical-cancer screening. Awareness of HPV infection and HPV-related cervical cancer was poor (28.2%).

Conclusions

Female IBD patients are at increased risk of high-risk HPV infection and cervical neoplasia, which may be associated with immunosuppressants. Education and routine follow-up with HPV-DNA testing and TCT are recommended, especially in female Chinese IBD patients.

Potential biomarkers and therapeutic targets in cervical cancer: Insights from the meta-analysis of transcriptomics data within network biomedicine perspective

The malignant neoplasm of the cervix, cervical cancer, has effects on the reproductive tract. Although infection with oncogenic human papillomavirus is essential for cervical cancer development, it alone is insufficient to explain the development of cervical cancer. Therefore, other risk factors such as host genetic factors should be identified, and their importance in cervical cancer induction should be determined. Although gene expression profiling studies in the last decade have made significant molecular findings about cervical cancer, adequate screening and effective treatment strategies have yet to be achieved. In the current study, meta-analysis was performed on cervical cancer-associated transcriptome data and reporter biomolecules were identified at RNA (mRNA, miRNA), protein (receptor, transcription factor, etc.), and metabolite levels by the integration of gene expression profiles with genome-scale biomolecular networks. This approach revealed already-known biomarkers, tumor suppressors and oncogenes in cervical cancer as well as various receptors (e.g. ephrin receptors EPHA4, EPHA5, and EPHB2; endothelin receptors EDNRA and EDNRB; nuclear receptors NCOA3, NR2C1, and NR2C2), miRNAs (e.g., miR-192-5p, miR-193b-3p, and miR-215-5p), transcription factors (particularly E2F4, ETS1, and CUTL1), other proteins (e.g., KAT2B, PARP1, CDK1, GSK3B, WNK1, and CRYAB), and metabolites (particularly, arachidonic acids) as novel biomarker candidates and potential therapeutic targets. The differential expression profiles of all reporter biomolecules were cross-validated in independent RNA-Seq and miRNA-Seq datasets, and the prognostic power of several reporter biomolecules, including KAT2B, PCNA, CD86, miR-192-5p and miR-215-5p was also demonstrated. In this study, we reported valuable data for further experimental and clinical efforts, because the proposed biomolecules have significant potential as systems biomarkers for screening or therapeutic purposes in cervical carcinoma.

Risk of human papillomavirus infection in women with rheumatic disease: cervical cancer screening and prevention

Human Papillomavirus (HPV) is the most common sexually transmitted infection in the USA, with over 14 million people acquiring HPV each year. HPV is also the cause of most anogenital cancers. About 90% of HPV infections spontaneously resolve over 3 years. However, about 10% remain as persistent infection defined as repeatedly detected in cervical samples. As HPV is controlled by local and systemic immune responses, individuals with immunosuppression are at risk for cervical cancer. It is hypothesized that immunosuppressed individuals are more likely to have HPV persistence, which is necessary for malignant transformation. Accordingly, women with rheumatic diseases such as SLE and RA are likely vulnerable to HPV infection and the progression of cervical disease. The HPV vaccine, given as a series of vaccinations, is safe and effective that can prevent HPV infection and cervical cancer. There is no contraindication to HPV vaccination for women to age 26 with rheumatic disease, as it is not live. As in the general population, timing is key for the efficacy of the HPV vaccine as the goal is to vaccinate prior to sexual debut and exposure to HPV. There are no formal recommendations for cervical cancer screening in women with rheumatic disease but recommendations for the HIV-positive population can be adopted, meaning to screen with a Pap test annually for three consecutive years and if all normal, to extend the interval to every 3 years with the option of co-testing with HPV at 30 years and older.

Vitamin D and juvenile systemic lupus erythematosus: Lights, shadows and still unresolved issues

Systemic lupus erythematosus (SLE) and juvenile SLE (jSLE) are autoimmune disorders naturally associated with several genetic, environmental, hormonal, and immunological contributing factors. It has been assumed that vitamin D deficiency may have a role in the immune activation of patients with SLE and play an active part in many comorbidities and even complications. A host of clinical studies suggested that vitamin D exerts inhibitory effects on many immunological abnormalities associated with SLE, also in children and adolescents, while different reports have hypothesized that vitamin D may be associated with accelerated cardiovascular disease in SLE. This review updates and summarizes the information related to the immunoregulatory effects of vitamin D and its importance in jSLE, discusses the innumerable correlations between vitamin D and disease activity, including clinical expression and gene polymorphisms of vitamin D receptor as well as the recommendations for vitamin D supplementation in these patients. Despite the excitement raised by many data obtained about vitamin D and its influence on several aspects of the disease, further well-designed perspective trials are required to define the exact role that vitamin D may have in the management of both SLE and jSLE.

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.

Vaccination Coverage of Adolescents With Chronic Medical Conditions

INTRODUCTION

Adolescents with chronic medical conditions (CMCs) are at increased risk of vaccine-preventable infections. Little is known about their vaccine uptake.

METHODS

This retrospective cohort study included 3,989 adolescents aged 11-17 years receiving care at academically affiliated pediatric clinics between August 2011 and June 2013. Data were abstracted from the medical center's electronic health record and immunization registry in 2014. Vaccination coverage, timeliness, and missed opportunities were evaluated and analyzed in 2015-2016.

RESULTS

Adolescents with CMCs had lower human papillomavirus vaccination initiation than those without CMCs (81.3% vs 85.0%), although this difference was only observed in stratified analysis among males (adjusted relative risk=0.90, 95% CI=0.85, 0.96), aged 13-17 years (adjusted relative risk=0.94, 95% CI=0.91, 0.98), and those with more primary care visits (adjusted relative risk=0.94, 95% CI=0.91, 0.98). Adolescents with CMCs had greater influenza vaccination coverage and timeliness than those without CMCs (2011-2012 season: 66.9% vs 50.1%; adjusted hazards ratio=1.27, 95% CI=1.15, 1.40; 2012-2013 season: 73.8% vs 64.5%; adjusted hazards ratio=1.20, 95% CI=1.10, 1.31). Only 32.1% and 18.2% of eligible adolescents had received pneumococcal polysaccharide and 13-valent pneumococcal conjugate vaccines, respectively. Missed opportunities were higher among adolescents with versus without CMCs for human papillomavirus vaccination initiation (4.2 vs 2.7, p<0.001), meningococcal vaccination (4.0 vs 2.9, p<0.001), and influenza vaccination (2011-2012 season: 2.1 vs 1.7, p<0.001; 2012-2013 season: 2.0 vs 1.6, p<0.001). Missed opportunities for pneumococcal vaccination were common.

CONCLUSIONS

Pockets of undervaccination and missed opportunities exist among adolescents with CMCs. Greater, more timely influenza vaccination suggests that optimal vaccination of high-risk adolescents is possible.

Text message reminders for vaccination of adolescents with chronic medical conditions: A randomized clinical trial

BACKGROUND

Many adolescents with chronic medical conditions (CMCs) are at risk of vaccine-preventable infection, yet are frequently under-vaccinated. Text message reminders, particularly those with embedded educational information, have been shown to increase general pediatric vaccination. Their use has not been studied specifically among adolescents with CMCs.

METHODS

Eligible parents of adolescents with CMCs receiving care at one of 4 academically-affiliated pediatric clinics and requiring human papillomavirus (first dose), influenza, and/or pneumococcal polysaccharide vaccines were randomized in 4 consecutive cohorts to receive text message vaccine reminders with or without embedded educational information ("educational" vs. "plain" arm, respectively). Educational reminders, including one interactive message, addressed infection risk, vaccine safety/efficacy, and physician recommendations. Up to 5 weekly and 2 booster reminders were sent (October 2014-January 2015). Receipt of any needed vaccine and missed vaccination opportunities by 4, 12, and 24weeks after the initial reminder were compared between arms.

RESULTS

Of randomized parents (n=295), 175 (59.3%) were Spanish-speaking; most had adolescents with CMCs who were 13-17years (n=229; 77.6%) and publically insured (n=272; 92.5%). Baseline demographics and parental vaccine beliefs were similar between arms. More adolescents in the plain vs. educational reminder arm received any needed vaccine by 4weeks (31.9% vs. 22.7%, adjusted relative risk [aRR] 1.47, 95% CI 1.01-2.14), but not by 12 or 24weeks. Plain reminders were noted in post hoc analyses to have a greater effect than educational reminders in certain sub-populations, including 11-12year-olds and those sent the initial reminder in early fall. Fewer adolescents in the plain vs. educational reminder arm had a missed vaccination opportunity by 4weeks (10.9% vs. 41.3%; aRR 0.21, 95% CI 0.07-0.60), but not by 12 or 24weeks.

CONCLUSION

Plain text message vaccine reminders appear to have a positive effect compared to educational ones in the short-term and for certain families.

Biologic Disease-Modifying Antirheumatic Drugs and Risk of High-Grade Cervical Dysplasia and Cervical Cancer in Rheumatoid Arthritis: A Cohort Study

OBJECTIVE

Recent research showed an increased risk of high-grade cervical dysplasia and cervical cancer associated with rheumatoid arthritis (RA). The purpose of this study was to examine whether this risk was associated with the use of biologic versus nonbiologic disease-modifying antirheumatic drugs (DMARDs).

METHODS

We identified RA patients in the US Medicaid and commercial insurance databases (for the years 2000-2012) who were starting treatment with either a biologic or a nonbiologic DMARD. High-grade cervical dysplasia or cervical cancer was identified with a validated claims-based algorithm, and we assessed utilization of gynecologic procedures. To control for potential confounders, those starting therapy with a biologic DMARD were matched 1:1 to those starting therapy with a nonbiologic DMARD according to the propensity score (PS). Hazard ratios (HRs) and rate ratios (RRs) in the PS-matched Medicaid and commercial insurance cohorts were pooled by an inverse variance-weighted fixed-effects model.

RESULTS

We included 14,729 pairs of patients initiating biologic and nonbiologic DMARDs from the Medicaid cohort and 7,538 pairs from the commercial insurance cohort. During 73,389 person-years of active treatment with either biologic or nonbiologic DMARDs, 95 cases of high-grade cervical dysplasia or cervical cancer occurred in the 2 cohorts. The HR for high-grade cervical dysplasia or cervical cancer associated with biologic DMARD use was 1.25 (95% confidence interval [95% CI] 0.78-2.01) in the Medicaid cohort and 1.63 (95% CI 0.62-4.27) in the commercial insurance cohort, with a pooled HR of 1.32 (95% CI 0.86-2.01). The rate of gynecologic procedures involving the uterine cervix was not different between the 2 groups (pooled RR 0.96 [95% CI 0.90-1.02]).

CONCLUSION

Among women with RA, initiation of therapy with a biologic DMARD was associated with a numerically significant, but not statistically significant, increase in the risk of high-grade cervical dysplasia or cervical cancer as compared to initiation of a nonbiologic DMARD.

Human Papillomavirus Vaccination of Adolescents with Chronic Medical Conditions: A National Survey of Pediatric Subspecialists

STUDY OBJECTIVE

Many adolescents with chronic medical conditions (CMCs) are at risk of human papillomavirus (HPV) infection, associated complications, and underimmunization and often identify a pediatric subspecialist as their main provider. This study aimed to assess the HPV-related understanding, beliefs, and practices of pediatric subspecialists, which are largely unknown.

DESIGN AND SETTING

National cross-sectional study.

PARTICIPANTS

Pediatric endocrinologists, hematologist/oncologists, pulmonologists, and rheumatologists identified using the American Medical Association Physician Masterfile (n = 418).

INTERVENTIONS

Subspecialists who care for adolescents with CMCs in the outpatient setting were recruited to complete a Web-based survey on their HPV-related knowledge, attitudes, comfort, and practices.

MAIN OUTCOME MEASURES

HPV vaccination recommendation.

RESULTS

Over half of respondents (50.4%; n = 196/389) reported sometimes or always recommending HPV vaccination to adolescent patients with CMCs. Factors positively associated with recommendation included hematology/oncology (adjusted odds ratio [AOR], 4.69; 95% confidence interval [CI], 1.86-11.81) or rheumatology (AOR, 6.55; 95% CI, 1.67-25.74) specialization, seeing more adolescent patients with CMCs (AOR, 1.01; 95% CI, 1.00-1.02), and sometimes or always discussing sexual health (AOR, 2.53; 95% CI, 1.05-6.08) or checking vaccine status (AOR, 3.83; 95% CI, 1.59-9.20) with these patients. Those who thought it was important, but were uncomfortable discussing sexual health when recommending HPV vaccination (AOR, 0.28; 95% CI, 0.12-0.70) or who reported insufficient HPV vaccine information (AOR, 0.45; 95% CI, 0.23-0.88) or lack of primary-subspecialty care provider communication (AOR, 0.38; 95% CI, 0.16-0.93) as barriers to HPV vaccination were less likely to recommend HPV vaccination.

CONCLUSION

This study revealed that many subspecialists fail to recommend HPV vaccination to adolescents with CMCs and highlights potential targets for future interventions.

Incidence of cervical human papillomavirus infection in systemic lupus erythematosus women

Objectives Our objective was to study the incidence, persistence and clearance of human papillomavirus infection in systemic lupus erythematosus women and assess risk factors for persistence of human papillomavirus infection. Methods We carried out a prospective, observational cohort study of 127 systemic lupus erythematosus women. Patients were evaluated at baseline and at three years. Traditional and systemic lupus erythematosus women-related disease risk factors were collected. Gynaecological evaluations and cervical cytology screening were made. Human papillomavirus detection and genotyping were made by polymerase chain reaction and linear array. Results The cumulative prevalence of human papillomavirus infection increased from 22.8% at baseline to 33.8% at three years; p = < 0.001: 20.1% of patients experienced 43 incident infections. The risk of any human papillomavirus infection was 10.1 per 1000 patient-months. At three years, 47 (88.6%) prevalent infections were cleared. Independent risk factors associated with incident human papillomavirus infection included more lifetime sexual partners (odds ratio = 1.8, 95% confidence interval = 1.11-3.0) and cumulative cyclophosphamide dose (odds ratio = 3.9, 95% confidence interval = 1.2-12.8). Conclusions In systemic lupus erythematosus women, the cumulative prevalence of human papillomavirus infection, including high risk-human papillomavirus and multiple human papillomavirus infections, may increase over time. Most persistent infections were low risk-human papillomavirus. The number of lifetime sexual partners and the cumulative cyclophosphamide dose were independently associated with incident human papillomavirus infection.

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.

Vaccination of Adult Patients with Systemic Lupus Erythematosus in Portugal

In the wake of the Portuguese vaccination program 50th anniversary it seems appropriate to review vaccination in patients with systemic lupus erythematosus. Controversial issues as regards the association between autoimmune diseases, infections, and vaccines are discussed as well as vaccine safety and efficacy issues as regards chronic immunosuppressant (IS) drug therapy. After a brief overview of national policies, specific recommendations are made as regards vaccination for adult patients with SLE with a particular focus on current IS therapy and unmet needs.

Vaccines, adjuvants and autoimmunity

Vaccines and autoimmunity are linked fields. Vaccine efficacy is based on whether host immune response against an antigen can elicit a memory T-cell response over time. Although the described side effects thus far have been mostly transient and acute, vaccines are able to elicit the immune system towards an autoimmune reaction. The diagnosis of a definite autoimmune disease and the occurrence of fatal outcome post-vaccination have been less frequently reported. Since vaccines are given to previously healthy hosts, who may have never developed the disease had they not been immunized, adverse events should be carefully accessed and evaluated even if they represent a limited number of occurrences. In this review of the literature, there is evidence of vaccine-induced autoimmunity and adjuvant-induced autoimmunity in both experimental models as well as human patients. Adjuvants and infectious agents may exert their immune-enhancing effects through various functional activities, encompassed by the adjuvant effect. These mechanisms are shared by different conditions triggered by adjuvants leading to the autoimmune/inflammatory syndrome induced by adjuvants (ASIA syndrome). In conclusion, there are several case reports of autoimmune diseases following vaccines, however, due to the limited number of cases, the different classifications of symptoms and the long latency period of the diseases, every attempt for an epidemiological study has so far failed to deliver a connection. Despite this, efforts to unveil the connection between the triggering of the immune system by adjuvants and the development of autoimmune conditions should be undertaken. Vaccinomics is a field that may bring to light novel customized, personalized treatment approaches in the future.

Who and how to screen for cancer in at-risk inflammatory bowel disease patients

Inflammatory bowel diseases (IBDs) include both Crohn's disease and ulcerative colitis and both diseases are marked by inflammation within the gastrointestinal tract. Due to long-standing inflammation, IBD patients are at increased risk of colorectal cancer, especially patients with chronic inflammation, pancolitis, co-diagnosis of primary sclerosing cholangitis and a longer duration of disease. Small bowel inflammation places Crohn's patients at an increased risk of small bowel cancer. A higher risk of skin cancers, lymphomas and cervical abnormalities is also seen in IBD patients; this is likely related to both disease factors and the presence of immunosuppressive medication. This article reviews which patients are at an increased risk of IBD-associated or IBD treatment-associated cancers, when to begin screening and which screening methods are recommended.

Role of vaccinations and prophylaxis in rheumatic diseases

Targeted strategies for reducing the increased risk of infection in patients with autoimmune rheumatic diseases include vaccinations as well as antibiotic prophylaxis in selected patients. However, there are still issues under debate: Is vaccination in patients with rheumatic diseases immunogenic? Is it safe? What is the impact of immunosuppressive drugs on vaccine immunogenicity and safety? Does vaccination cause disease flares? In which cases is prophylaxis against Pneumocystis jirovecii required? This review addresses these important questions to which clinicians and researchers still do not have definite answers. The first part includes immunization recommendations and reviews current data on vaccine efficacy and safety in patients with rheumatic diseases. The second part discusses prophylaxis for Pneumocystis pneumonia.

Human papillomavirus vaccine uptake among individuals with systemic inflammatory diseases

Objectives

The human papillomavirus (HPV) vaccine is safe and efficacious in patients with systemic inflammatory diseases (SID) who have higher rates of persistent HPV infection. We compared HPV vaccine uptake among SID and non-SID patients.

Methods

Using a U.S. insurance claims database (2006–2012), we identified individuals 9–26 years with ≥2 SID diagnosis codes ≥7 days apart with ≥12 months of continuous enrollment prior to the second code (index date). We matched SID patients by age, sex and index date to randomly selected non-SID subjects and selected those with ≥24 months of post-index date continuous follow-up. We also identified a non-SID subcohort with ≥1 diagnosis code for asthma. We defined initiation as ≥1 HPV vaccination claim after 2007, and completion as 3 claims. We used multivariable logistic regression to assess uptake in females 11–26 years comparing SID, non-SID and asthma cohorts, adjusting for demographics, region, comorbidities, and healthcare utilization.

Results

We identified 5,642 patients 9–26 years with SID and 20,643 without. The mean age was 18.1 years (SD 4.9). We identified 1,083 patients with asthma; the mean age was 17.2 (SD 5.1). Among females, 20.6% with SID, 23.1% without SID and 22.9% with asthma, received ≥1 HPV vaccine. In our adjusted models, the odds of receipt of ≥1 vaccine was 0.87 times lower in SID (95% CI 0.77–0.98) compared to non-SID and did not differ for 3 vaccines (OR 1.03, 95% CI 0.83–1.26). The odds of initiation and completion were not statistically different between SID and non-SID asthma cohorts.

Conclusions

In this nationwide cohort, HPV vaccine uptake was extremely low. Despite the heightened risk of persistent HPV infection among those with SID, no increase in HPV vaccine uptake was observed. Public health efforts to promote HPV vaccination overall are needed, and may be particularly beneficial for those at higher risk.

Behavioral and clinical factors associated with self-reported abnormal Papanicolaou tests in rheumatoid arthritis

BACKGROUND

Some evidence suggests that women with rheumatoid arthritis (RA) are at increased risk for the development of cervical cancer; however, it is unclear how this increase risk is conferred. We aimed to assess the factors related to abnormal Papanicolaou (Pap) tests in women with RA to determine whether they are similar to those reported for the general population.

METHODS

A structured questionnaire was mailed to 503 female patients from a longitudinal RA cohort. The survey included items on sociodemographic, behavioral, and gynecological factors. Univariate and multivariable logistic regression models examined the association of self-reported abnormal Pap results with a number of potential behavioral risk factors.

RESULTS

The questionnaire response rate was 57.5% (n=289). Median age was 61 years and 97% had ≥1 Pap test previously. Twenty-nine percent of respondents reported a previous abnormal Pap result. In the multivariable logistic model adjusted for age, number of lifetime sexual partners, age at menarche, birth control use, and history of sexually transmitted disease (STD), ever using birth control (odds ratio [OR] 2.31, 95% confidence interval [CI] 1.18-4.52) and previous STD (OR 3.38, 95% CI 1.70-6.70) were associated with an increased risk of abnormal Pap result. Compared with either the state or national population, a greater proportion of the respondents was older, married, and previous smokers, and completed postsecondary education and obtained a Pap test.

CONCLUSIONS

In this cross-sectional study, self-reported abnormal Pap results were associated with use of birth control and history of STD in RA patients.

Lack of association between serum 25-hydroxyvitamin D levels and cervical human papillomavirus infection in systemic lupus erythematosus

Our objective was to evaluate whether vitamin D deficiency is associated with cervical human papilloma virus (HPV) infection in women with SLE. This is a cross-sectional study of 67 women with SLE. A structured questionnaire was administered to ascertain the possible risk factors associated with cervical HPV infection. A gynaecological evaluation and cervical cytology screening were made. HPV detection and genotyping was made by PCR and linear array assay. Serum 25 hydroxyvitamin D levels were quantified by chemiluminescence immunoassay. Mean age and disease duration were 44.8 ± 10.6 and 42.5 ± 11.8 years, respectively. Demographic characteristics were similar in patients with and without deficiency (<20 ng/ml and ≥20 ng/ml). There were 28.4% of women with cervical HPV infection and 68.4% had high-risk HPV infections. Patients with 25 hydroxyvitamin D levels <20 ng/ml had a higher prevalence of cervical HPV infection than those with levels ≥20 ng/ml (30.7% vs. 25.8%; p = 0.72). We found no significant difference when high-risk HPV infection was evaluated (36.8% vs. 31.5%; p = 0.73). In conclusion, women with SLE have a high prevalence of vitamin D deficiency and cervical HPV infection. However, we found no association between vitamin D deficiency and cervical HPV.

Human papillomavirus and chlamydia trachomatis infections in rheumatoid arthritis under anti-TNF therapy: an observational study

The objective of this study was to evaluate human papillomavirus (HPV) and Chlamydia trachomatis (CT) infections in RA patients pre- and post-TNF blocker. Fifty female RA patients (ACR criteria), who were eligible to anti-TNF therapy [n = 50 at baseline (BL) and n = 45 after 6 months of treatment (6 M)], and 50 age-matched healthy controls were prospectively enrolled. They were assessed for demographic data, gynecologic, sexual, cervical cytology and histological evaluations, disease parameters and current treatment. HPV DNA and CT DNA testing in cervical specimens were done using Hybrid Capture II assays. At BL, the median current age of RA patients and controls was 49 (18-74) versus 49 (18-74) years, p = 1.0. A trend of lower frequency of HPV infection was observed in AR patients pre-anti-TNF compared with controls (14 vs. 30%, p = 0.054). Further evaluation of AR patients with and without HPV infection before anti-TNF therapy showed that the former group had higher frequency of sexual intercourses (100 vs. 48%, p = 0.014), higher median number of sexual partners [1 (1-1) vs. 0 (0-1), p = 0.032] and higher frequency of abnormal cervical cytology (43 vs. 7%, p = 0.029). Current age, disease duration, disease parameters and treatments were alike in both groups (p > 0.05). At 6 M after TNF blockage, HPV infection remained unchanged in five patients, whereas two became negative and one additional patient turned out to be positive (p = 1.0). CT infection was uniformly negative in RA patients pre- and post-TNF blockage and in controls. Anti-TNF does not seem to increase short-term risk of exacerbation and/or progression of HPV and CT infections in RA patients.

Should we target patients with autoimmune diseases for human papillomavirus vaccine uptake?

Human papillomavirus (HPV) is the cause of most cases of cervical cancer worldwide. Studies suggest that patients with autoimmune diseases (AD) may be at increased risk for persistent HPV infection, cervical dysplasia, and possibly, cervical cancer. Despite this heightened risk, and studies demonstrating the safety and efficacy of the HPV vaccine in this population, uptake among patients with AD, and in the overall population, remains low. A number of studies suggest that this may be attributed to lack of patient and provider awareness, no school-based requirement for vaccination, and a hesitancy to discuss sexually transmitted diseases with adolescents. Among patients with AD, access to preventive care in general may be reduced. Overall, heightened public health efforts are needed to improve HPV vaccination uptake in the entire population and among patients with AD who may be at increased risk for persistent infection and for cervical dysplasia.

Risk of high-grade cervical dysplasia and cervical cancer in women with systemic inflammatory diseases: a population-based cohort study

BACKGROUND

Previous studies have suggested a potential risk of cervical cancer in patients with systemic inflammatory diseases (SID) such as inflammatory bowel disease (IBD) and systemic lupus erythematosus (SLE).

OBJECTIVES

To assess the risk of high-grade cervical dysplasia, a surrogate endpoint for cervical cancer and cervical cancer, in women with SID, including IBD, psoriasis, rheumatoid arthritis (RA) or SLE, compared with the risk in women without SID.

METHODS

Using US insurance data (2001-2012), we conducted a cohort study of 133,333 women with SID, based on two or more diagnoses and one or more dispensed prescription for disease-specific treatment, and 533,332 women without SID. High-grade cervical dysplasia and cervical cancer was defined by a validated algorithm with a positive predictive value of ≥81%.

RESULTS

Over the mean follow-up of 2.1 years, the crude incidence rate of high-grade cervical dysplasia and cervical cancer per 100,000 person-years was the highest at 141.1 in SLE and the lowest at 82.2 in psoriasis among women with SID, and 73.4 in women without SID. The multivariable HR adjusted for potential confounders was 1.07 (95% CI 0.79 to 1.45) in IBD, 0.96 (95% CI 0.73 to 1.27) in psoriasis, 1.49 (95% CI 1.11 to 2.00) in RA and 1.53 (95% CI 1.07 to 2.19) in SLE. Multivariable HRs were increased, but not statistically significant, in IBD, RA and SLE with baseline use of systemic immunosuppressive drugs or steroids.

CONCLUSIONS

The risk of high-grade cervical dysplasia and cervical cancer was 1.5 times higher in women with RA and SLE than in those without SID. The risk may be increased in IBD with use of systemic immunosuppressive drugs or steroids.

The impact of glucocorticoids and anti-cd20 therapy on cervical human papillomavirus infection risk in women with systemic lupus erythematosus

OBJECTIVE

To identify the prevalence and factors associated with cervical human papillomavirus infection in women with systemic lupus erythematosus

METHODS

This cross-sectional study collected traditional and systemic lupus erythematosus-related disease risk factors, including conventional and biologic therapies. A gynecological evaluation and cervical cytology screen were performed. Human papillomavirus detection and genotyping were undertaken by PCR and linear array assay.

RESULTS

A total of 148 patients were included, with a mean age and disease duration of 42.5±11.8 years and 9.7±5.3 years, respectively. The prevalence of squamous intraepithelial lesions was 6.8%. The prevalence of human papillomavirus infection was 29%, with human papillomavirus subtype 59 being the most frequent. Patients with human papillomavirus were younger than those without the infection (38.2±11.2 vs. 44.2±11.5 years, respectively; p = 0.05), and patients with the virus had higher daily prednisone doses (12.8±6.8 vs. 9.7±6.7 mg, respectively; p = 0.01) and cumulative glucocorticoid doses (14.2±9.8 vs. 9.7±7.3 g, respectively; p = 0.005) compared with patients without. Patients with human papillomavirus infection more frequently received rituximab than those without (20.9% vs. 8.5%, respectively; p = 0.03). In the multivariate analysis, only the cumulative glucocorticoid dose was associated with human papillomavirus infection.

CONCLUSIONS

The cumulative glucocorticoid dose may increase the risk of human papillomavirus infection. Although rituximab administration was more frequent in patients with human papillomavirus infection, no association was found. Screening for human papillomavirus infection is recommended in women with systemic lupus erythematosus.

Immunosuppression and risk of cervical cancer

A markedly increased risk of cervical cancer is known in women immunosuppressed due to AIDS or therapy following organ transplantation. The aim of this review is to determine the association between other conditions affecting the immune system and the risk of cervical cancer. Patients with end-stage renal disease seem to be at an increased risk of cervical cancer. A higher risk of cervical precancerous lesions was found in patients with some autoimmune diseases; particularly if treated with immunosuppressants. Among behavioral factors weakening the immune system, smoking appeared to strongly increase the risk of cervical cancer, while poor diet only moderately increased the risk. It is difficult to determine whether sexually transmitted infections other than human papillomavirus infection are independent risk factors. Identifying those groups of women likely to fail in clearing persistent human papillomavirus infections would help individualize screening guidelines and target immune-associated factors in the cervical cancer etiology.

IL-32 with potential insights into rheumatoid arthritis

Rheumatoid arthritis (RA) is an autoimmune disease, characterized by chronic inflammation in synovial joints. Effective treatment for RA is lacking because the clear etiology and pathogenesis of RA have not been fully elucidated. Cytokine-mediated immunity has been found to play an important role in the pathogenesis of various autoimmune diseases such as RA. Recently, IL-32 is identified with high expression in RA patients and mice models of experimental inflammatory arthritis. IL-32 is recognized to play a crucial role in RA with pro-inflammatory effects. Furthermore, interventions for blocking IL-32 in RA seem possible and applicable. Therefore, targeting IL-32 may give therapeutic potential. In this article, we discuss the biological features of IL-32 and summarize recent advances in understanding the role of IL-32 in disease onset of and treatment for RA. Hopefully the information obtained will benefit for developing novel therapeutic strategies.
