Is Higher Prevalence of Cervical Intraepithelial Neoplasia in Women With Lupus Due to Immunosuppression?

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.

Risk factors for human papillomavirus infection, cervical intraepithelial neoplasia and cervical cancer: an umbrella review and follow-up Mendelian randomisation studies

BACKGROUND

Persistent infection by oncogenic human papillomavirus (HPV) is necessary although not sufficient for development of cervical cancer. Behavioural, environmental, or comorbid exposures may promote or protect against malignant transformation. Randomised evidence is limited and the validity of observational studies describing these associations remains unclear.

METHODS

In this umbrella review, we searched electronic databases to identify meta-analyses of observational studies that evaluated risk or protective factors and the incidence of HPV infection, cervical intra-epithelial neoplasia (CIN), cervical cancer incidence and mortality. Following re-analysis, evidence was classified and graded based on a pre-defined set of statistical criteria. Quality was assessed with AMSTAR-2. For all associations graded as weak evidence or above, with available genetic instruments, we also performed Mendelian randomisation to examine the potential causal effect of modifiable exposures with risk of cervical cancer. The protocol for this study was registered on PROSPERO (CRD42020189995).

RESULTS

We included 171 meta-analyses of different exposure contrasts from 50 studies. Systemic immunosuppression including HIV infection (RR = 2.20 (95% CI = 1.89-2.54)) and immunosuppressive medications for inflammatory bowel disease (RR = 1.33 (95% CI = 1.27-1.39)), as well as an altered vaginal microbiome (RR = 1.59 (95% CI = 1.40-1.81)), were supported by strong and highly suggestive evidence for an association with HPV persistence, CIN or cervical cancer. Smoking, number of sexual partners and young age at first pregnancy were supported by highly suggestive evidence and confirmed by Mendelian randomisation.

CONCLUSIONS

Our main analysis supported the association of systemic (HIV infection, immunosuppressive medications) and local immunosuppression (altered vaginal microbiota) with increased risk for worse HPV and cervical disease outcomes. Mendelian randomisation confirmed the link for genetically predicted lifetime smoking index, and young age at first pregnancy with cervical cancer, highlighting also that observational evidence can hide different inherent biases. This evidence strengthens the need for more frequent HPV screening in people with immunosuppression, further investigation of the vaginal microbiome and access to sexual health services.

Cervical Health in Systemic Lupus Erythematosus

Objective

A health disparity exists for African American (AA) women with systemic lupus erythematosus (SLE) who have increased prevalence of human papilloma virus (HPV) infection and cervical neoplasia. We used a self-sampling brush to obtain cervical cells to assess cytology, HPV infection, and vaginal cytokine production in AA women with SLE.

Methods

Thirty AA women with SLE ages 18-50 years consented to participate. Clinical information was obtained by review of records and patient interviews, and surveys administered to assess cervical health history, knowledge of HPV, and satisfaction with the self-sampling brush. Vaginal samples were analyzed for cytology, HPV DNA and RNA, and vaginal cytokine RNA.

Results

Our cohort (mean 36.9, ±9.4 years) had moderate/severe SLE and were on immunosuppressives. The majority had history of abnormal pap smears (63%) with prevalent risk factors for HPV infection: multiple sex partners (9.5 ± 7), not vaccinated for HPV (83.3%), smoking (26.7%), and not using condoms (73.3%). Most were aware of HPV causing cervical cancer (70%) but were unaware of other HPV-related diseases. Most preferred self-sampling over traditional pap smear (80%). Abnormal cytology was detected in 13.3%. HPV DNA was detected in 70%, with half showing multiple types, and all showing active infection (+RNA). HPV-infected samples demonstrated RNA expression of multiple cytokines with no specific/ consistent pattern.

Conclusion

Our high-risk cohort lacked knowledge about HPV-related diseases and were not employing strategies to reduce their risk with vaccination and condoms. This study highlights the need for cervical health education, increased monitoring, and intervention in these high-risk women.

Cancer occurrence after SLE: effects of medication-related factors, disease-related factors and survival from an observational study

OBJECTIVES

To explore the survival and risk factors for cancer occurrence after SLE (SLE-CA).

METHODS

Patients with cancer diagnosed after SLE in Peking Union Medical College Hospital between January 2006 and September 2017 were recruited and followed. Data regarding medication-related and disease-related factors and survival were collected and compared with matched controls. Logistic regressions were applied to identify risk factors. The Kaplan-Meier method with a log-rank test was performed to evaluate survival.

RESULTS

Forty-five SLE-CA patients and 128 controls were included, with the most common cancer site being the female genital system. SLE-CA patients were exposed to a higher cumulative dosage of CYC, with less mucocutaneous and haematologic involvement and higher anti-dsDNA positivity. At the time of cancer diagnosis, SLE-CA patients had lower SLEDAI 2000 (SLEDAI-2K), tended to achieve Definitions of Remission in SLE remission and minimal disease activity, but had higher SLICC/ACR Damage Index. Multivariable analysis identified high dosage of CYC [odds ratio (OR) 1.027, 95% CI 1.008, 1.046; P = 0.005] and low SLEDAI-2K at cancer diagnosis (OR 0.756, 95% CI 0.579, 0.986; P = 0.039) as risk factors. Mucocutaneous (OR 0.330, 95% CI 0.110, 0.991; P = 0.048) and haematologic involvement (OR 0.304, 95% CI 0.103, 0.902; P = 0.032) were negatively associated with cancer occurrence after SLE. The 5- and 10-year survival rates in SLE-CA patients were 95.2% and 92.1%, respectively. No significant difference of survival was observed between SLE-CA patients and controls (P = 0.177).

CONCLUSION

High dosage of CYC and disease-related factors (low SLEDAI-2K, less mucocutaneous and haematologic involvement) were related factors for cancer occurrence after SLE, while no survival difference was observed.

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.

Association between systemic lupus erythematosus and risk of cervical atypia: A meta-analysis

BACKGROUND

Previous studies showed conflicting results regarding the association between systemic lupus erythematosus (SLE) and risk of cervical atypia. Therefore, the present study aimed to make a meta-analysis to summarize results of studies regarding association between SLE and risk of cervical atypia.

METHODS

We searched for articles published before March 2021 in in the following databases: PubMed, EMBASE, Web of Science, Medline and Google Scholar. Odds ratios (ORs) and relative risks (RRs) with their 95% confidence intervals (CIs) were computed to create a pooled effect size and 95% CI using STATA 12.0 software.

RESULTS

The present meta-analysis showed that SLE was significantly associated with increased risks of cervical atypia (OR/RR = 2.94, 95% CI 2.22 to 3.89, I² = 92.1%, p < .001), cervical cancer (OR/RR = 3.13, 95% CI 2.09 to 4.70, I² = 84.7%, p < .001), squamous intraepithelial lesion (SIL) (OR/RR = 5.00, 95% CI 2.58 to 9.69, I² = 88.9%, p < .001) and low-grade SIL (OR/RR = 3.14, 95% CI 1.29 to 7.67, I² = 63.3%, p = .018) with random effects models.

CONCLUSION

In summary, findings of this meta-analysis demonstrated that SLE was associated with a higher risk of cervical pre-malignant lesions and carcinoma. It may be necessary for clinicians to remind women with SLE to screen human papillomavirus infection and be vaccinated as soon as possible. However, caution is required when interpreting our findings. Further studies, especially well-designed randomized controlled clinical trials are awaited to confirm the association between SLE and cervical atypia-associated diseases.

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.

Cancer and Systemic Lupus Erythematosus

Systemic lupus erythematosus is associated with a small overall increased cancer risk compared with the general population. This risk includes a 4-fold increased risk of non-Hodgkin lymphoma, but a decreased risk of other cancers (such as breast cancer). The pathophysiology underlying the increased risk of hematologic cancer is not fully understood, but many potential mechanisms have been proposed, including dysfunction of the tumor necrosis factor and other pathways. A decreased risk of breast, ovarian, and endometrial cancer might be driven by hormonal factors or lupus-related antibodies, but these links have not been proved.

Factors Associated with Development of High-Grade Squamous Intraepithelial Lesions of the Uterine Cervix in Women Younger than 30 Years

Objective:

To determine the factors associated with the increased risk of developing high-grade squamous intraepithelial lesions (HSIL) of the uterine cervix in women younger than 30 years compared with those aged ≥ 30 years who also had HSIL.

Methods:

Patients with HSIL who underwent loop electrosurgical excision procedure (LEEP) between January 2006 and July 2017 at Chiang Mai University Hospital were retrospectively reviewed. We analyzed the factors associated with the development of HSIL by comparing two age groups between women aged < 30 years and those aged ≥ 30 years. The factors analyzed included the well-recognized risk factors for cervical cancer, i.e. age at sexual debut, number of sexual partners, use of oral contraceptive (OC) pills, smoking history, sexually transmitted diseases and HIV status. Univariate and multivariate logistic regressions were used to assess factors associated with the increased risk of developing HSIL in women younger than 30 years compared with those aged ≥ 30 years.

Results:

During the study period, there were 345 patients with HSIL, 30 were < 30 years (case group) and 315 aged ≥ 30 years (control group). By multivariate analyses , early sexual debut(OR, 2.86; 95% CI, 1.01-8.13; P=0.047), multiple sexual partners (OR, 2.94; 95% CI, 1.23-7.02; P=0.015), history of genital warts (OR, 20.46; 95% CI, 2.27-183.72; P=0.007) and history of smoking (OR, 2.95; 95% CI, 1.10-7.93; P=0.032) were significantly associated with the development of HSIL in women younger than 30 years when compared with those aged ≥ 30 years. The OC use, HIV status and underlying diseases were not significantly different in both groups.

Conclusion:

Early age at sexual debut, multiple sexual partners, history of genital warts and smoking are significant risk factors for developing HSIL in women younger than 30 years. Cervical cancer screening should be considered in young women with such factors.

Systemic lupus erythematosus is a risk factor for cancer: a nationwide population-based study in Korea

OBJECTIVE

Specific differences in cancer risk have been observed between systemic lupus erythematosus patients and the general population. Although meta-analyses have estimated cancer incidence in systemic lupus erythematosus patients, results have been inconclusive. Hence, we aimed to assess malignancy risk in systemic lupus erythematosus patients, compared to the risk in the general population.

METHODS

Systemic lupus erythematosus patients ( n = 21,016; mean age 41.67 ± 13.14 years; female 90.22%) were selected from the Korean National Health Insurance Service database between 2008 and 2014. Age- and sex-matched controls were randomly sampled in a 5:1 ratio ( n = 105,080).

RESULTS

During the 7 years of follow up, malignancy was detected in 763 (3.63%) systemic lupus erythematosus patients and 2667 (2.54%) controls. Systemic lupus erythematosus patients had a higher risk of malignancy than controls (odds ratio 1.44; 95% confidence interval 1.327-1.559), after multivariate adjustment. Systemic lupus erythematosus patients had a higher odds ratio for developing cervical, thyroid, ovarian, and oral cancer, as well as lymphoma, leukemia, and multiple myeloma than controls. Based on subgroup analysis, male systemic lupus erythematosus patients and patients younger than 40 years showed the highest lymphoma risk.

CONCLUSIONS

Systemic lupus erythematosus might be an independent risk factor for cancer. Therefore, the importance of cancer screening programs should be emphasized in systemic lupus erythematosus patients. Our study is the first large nationwide cohort study for evaluating the risk of cancer in systemic lupus erythematosus patients.

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.

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.

Cumulative immunosuppressant exposure is associated with diversified cancer risk among 14 832 patients with systemic lupus erythematosus: a nested case-control study

Objectives

Immunosuppressive therapy is necessary to alter the natural course of SLE. However, immunosuppressant-related cancer risk is a major concern. The aim of this study was to determine whether immunosuppressant use is associated with cancer risk in SLE.

Methods

We designed a retrospective nested case-control study within an SLE population based on the National Health Insurance Research Database in Taiwan. We screened 14 842 patients with SLE from 2001 to 2013 and compared patients with SLE complicated by later cancer with patients with SLE but without cancer. The cumulative dose of immunosuppressants was calculated from the SLE diagnosis date to the occurrence of cancer. The immunosuppressants of interest were AZA, CYC, MTX, HCQ and systemic glucocorticoids. Adjusted odds ratios (ORs) for cancer were calculated in conditional Cox regression models after propensity score matching.

Results

The top five types of cancers were breast (16.9%), haematological (11.7%), colorectal (11.0%), lung (10.6%) and hepatobiliary (10.4%) cancers. After matching, this study included 330 cancer patients and 1320 matched cancer-free patients. The adjusted analyses showed an association of a higher cumulative CYC dose (OR = 1.09, 95% CI: 1.04, 1.13) and lower HCQ dose (OR = 0.93, 95% CI: 0.90, 0.97) with cancer risk in comparison with the controls.

Conclusion

Diverse cancer risks are associated with different immunosuppressants in patients with SLE. CYC increases the risk of cancer, and HCQ decreases this risk in SLE patients, both in a dose-dependent manner.

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.

Polymorphisms in NAT2 (N-acetyltransferase 2) gene in patients with systemic lupus erythematosus

OBJECTIVE

To investigate potential associations of four substitutions in NAT2 gene and of acetylator phenotype of NAT2 with systemic lupus erythematosus (SLE) and clinical phenotypes.

METHODS

Molecular analysis of 481C>T, 590G>A, 857G>A, and 191G>A substitutions in the NAT2 gene was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique, from DNA extracted from peripheral blood samples obtained from patients with SLE (n=91) and controls (n=97).

RESULTS AND CONCLUSIONS

The 857GA genotype was more prevalent among nonwhite SLE patients (OR=4.01, 95% CI=1.18-13.59). The 481T allele showed a positive association with hematological disorders that involve autoimmune mechanisms, specifically autoimmune hemolytic anemia or autoimmune thrombocytopenia (OR=1.97; 95% CI=1.01-3.81).

EULAR recommendations for women's health and the management of family planning, assisted reproduction, pregnancy and menopause in patients with systemic lupus erythematosus and/or antiphospholipid syndrome

Objectives

Develop recommendations for women's health issues and family planning in systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS).

Methods

Systematic review of evidence followed by modified Delphi method to compile questions, elicit expert opinions and reach consensus.

Results

Family planning should be discussed as early as possible after diagnosis. Most women can have successful pregnancies and measures can be taken to reduce the risks of adverse maternal or fetal outcomes. Risk stratification includes disease activity, autoantibody profile, previous vascular and pregnancy morbidity, hypertension and the use of drugs (emphasis on benefits from hydroxychloroquine and antiplatelets/anticoagulants). Hormonal contraception and menopause replacement therapy can be used in patients with stable/inactive disease and low risk of thrombosis. Fertility preservation with gonadotropin-releasing hormone analogues should be considered prior to the use of alkylating agents. Assisted reproduction techniques can be safely used in patients with stable/inactive disease; patients with positive antiphospholipid antibodies/APS should receive anticoagulation and/or low-dose aspirin. Assessment of disease activity, renal function and serological markers is important for diagnosing disease flares and monitoring for obstetrical adverse outcomes. Fetal monitoring includes Doppler ultrasonography and fetal biometry, particularly in the third trimester, to screen for placental insufficiency and small for gestational age fetuses. Screening for gynaecological malignancies is similar to the general population, with increased vigilance for cervical premalignant lesions if exposed to immunosuppressive drugs. Human papillomavirus immunisation can be used in women with stable/inactive disease.

Conclusions

Recommendations for women's health issues in SLE and/or APS were developed using an evidence-based approach followed by expert consensus.

Development of multiple malignancies following long-term glucocorticoid therapy in a patient with leukocytoclastic vasculitis: A case report

Leukocytoclastic vasculitis (LCV) is a neutrophilic inflammation of the blood vessels. LCV may present as a paraneoplastic syndrome occurring before, synchronously with, or after the diagnosis of malignancy. In this study, we report a unique case of multiple malignancies developing simultaneously in a patient with a long history of LCV. The patient was originally diagnosed with LCV and received long-term glucocorticoid treatment. After 11 years of therapy, the patient developed three primary malignancies, including small-cell lung carcinoma, gastric adenocarcinoma and colonic adenocarcinoma. It is likely that LCV was not a paraneoplastic syndrome in this case, but rather an independent process, and the development of multiple cancers is likely associated with the long-term glucocorticoid treatment, which caused imbalance of the immune system. Although the development of cancer during the course of glucocorticoid treatment is very rare, clinicians must be aware of this possible association and immunodysregulation may play a role in this context.

Effectiveness of pharmaceutical care for drug treatment adherence in patients with systemic lupus erythematosus in Rio de Janeiro, Brazil: study protocol for a randomized controlled trial

Background

Treatment adherence is a primary determinant of the success and effectiveness of healthcare. Lack of adherence can lead to treatment failure and death. Although studies have shown that pharmaceutical intervention can improve drug treatment for patients with chronic diseases, studies on pharmaceutical care are not only inconsistent, they are scarce and limited to developed countries, include few patients, and are not studied in randomized clinical trials. Systemic lupus erythematosus is an autoimmune disease with high hospitalization and case-fatality rates. The adherence rate is low (31.7 %) in this group of patients in Brazil, and drug treatment for the disease is complex. Our objective is to evaluate the effectiveness of pharmaceutical care in drug treatment adherence in patients with systemic lupus erythematosus treated at a rheumatology outpatient clinic in Rio de Janeiro, Brazil.

Methods

A randomized clinical trial (pragmatic trial) will be conducted. Adult participants (women) from a public hospital in Rio de Janeiro with a diagnosis of systemic lupus erythematosus will be followed for 12 months. A total of 120 patients will be randomized to two groups: intervention (Dader method for pharmaceutical care) and control (health/dietary counseling and risk reduction). The primary outcome will be drug treatment adherence evaluated by the eight-item Morisky Medication Adherence Scale. Secondary outcomes will be clinical improvement and quality of life.

Discussion

Patients with systemic lupus erythematosus present with low treatment adherence, thus justifying the mobilization of human resources to optimize their clinical management. Despite the proven effectiveness of pharmaceutical care for various diseases, there are still no studies evaluating its effectiveness in systemic lupus erythematosus. Our hypothesis is that the intervention will also be effective in this patient group.

Gynäkologische Malignome bei Patientinnen mit rheumatisch‑entzündlichen Systemerkrankungen

Das Risiko für gynäkologische Tumoren bei rheumatisch-entzündlichen Systemerkrankungen scheint nur in Bezug auf das Zervixkarzinom v. a. bei systemischem Lupus erythematodes erhöht zu sein. Studien weisen auf die Bedeutung des Immunsystems für die Tumorkontrolle bei gynäkologischen Tumoren hin. Bislang konnte aber nur für das Zervixkarzinom ein ungünstiger Einfluss einer medikamentösen Immunsuppression bei rheumatologischen Patientinnen gezeigt werden. Biologika wirken sich bei dieser Entität dagegen nicht eindeutig tumorfördernd aus. Die Datenlage bei dieser Fragestellung ist allerdings begrenzt. Generelle Screeningempfehlungen existieren für das Mammakarzinom und das Zervixkarzinom. Empfehlungen zur Tumornachsorge werden dargestellt. Aufgrund der unzureichenden Datenlage empfiehlt sich zumindest in den ersten 5 Jahren nach kurativer onkologischer Therapie eine sehr strenge Indikationsstellung zum Einsatz von Immunsuppressiva und Biologika auch bei gynäkologischen Tumoren. Im Falle des Mammakarzinoms wird sogar die Beachtung eines längeren Intervalls diskutiert.

Vaccinations in paediatric rheumatology: an update on current developments

In 2011, the European League Against Rheumatism (EULAR) published recommendations regarding the vaccination of children with rheumatic diseases. These recommendations were based on a systematic literature review published in that same year. Since then, the evidence body on this topic has grown substantially. This review provides an update of the systematic literature study of 2011, summarizing all the available evidence on the safety and immunogenicity of vaccination in paediatric patients with rheumatic diseases. The current search yielded 21 articles, in addition to the 27 articles described in the 2011 review. In general, vaccines are immunogenic and safe in this patient population. The effect of immunosuppressive drugs on the immunogenicity of vaccines was not detrimental for glucocorticosteroids and methotrexate. Biologicals could accelerate a waning of antibody levels over time, although most patients were initially protected adequately. Overall, persistence of immunological memory may be reduced in children with rheumatic diseases, which shows the need for (booster) vaccination. This update of the 2011 systematic literature review strengthens the evidence base for the EULAR recommendations, and it must be concluded that vaccinations in patients with rheumatic diseases should be advocated.

What investigations are needed to optimally monitor for malignancies in SLE?

Objective

The overall cancer incidence risk in systemic lupus erythematosus (SLE) is approximately 15%–20% more than in the general population. Nevertheless, to date, the optimal malignancy screening measures in SLE remain undefined. Our objective is to determine what investigations are needed to optimally monitor for malignancies in SLE in order to inform upcoming Canadian Rheumatology Association recommendations.

Methods

We conducted a systematic search looking at three scientific sources, Embase, Medline and Cochrane, in an attempt to identify cancer screening recommendations for patients with SLE. We used a filter for observational studies and included articles published in 2000 and onward.

Results

The initial search strategy led to 986 records. After removal of duplicates and articles unrelated to SLE, we were left with 497 titles. From those, 79 research articles on cancer incidence in SLE were isolated and reviewed. Of the 79 original research papers, 25 offered screening recommendations, 14 suggested additional cancer screening whereas 11 studies simply promoted adherence to general population screening measures. The suggestions for more rigorous screening included recommending human papilloma virus testing in addition to routine cervical screening, and/or that cervical screening should be performed annually and/or suggested urine cancer screening in SLE patients with a history of cyclophosphamide exposure.

Conclusions

We found no original research studies directly comparing cancer screening strategies in SLE. Generally, authors recommend adherence to general population screening measures, particularly cervical screening. This, possibly with adding targeted screening in special cases (e.g. annual urine cytology in patients with prior cyclophosphamide exposure, and considering existing lung cancer screening guidelines for past heavy smokers), may be a reasonable approach for cancer screening in SLE.

Human papillomavirus-related high-grade squamous intraepithelial lesions of the esophagus, skin, and cervix in an adolescent lung transplant recipient: a case report and literature review

High-risk (carcinogenic) genotype human papillomavirus (HPV) infections can be associated with significant morbidity in the immunocompromised solid organ transplant (SOT) recipient. Immunosuppression-associated persistent infection can predispose to the development of rapidly progressive high-grade squamous intraepithelial lesions (HSIL) in this population. We present a case report of an adolescent bilateral lung transplant recipient who developed HSIL of the esophagus, cervix, and skin secondary to HPV. This review highlights the unique developmental needs of the sexually active adolescent SOT recipient and reviews guidelines for HPV-related screening and education of this population.

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.

Cutaneous papillomavirus infection in patients with rheumatoid arthritis or systemic lupus erythematosus. A case-control study

Previous studies informed an increased prevalence of cutaneous papillomavirus (cHPV) infection in patients with systemic lupus erythematosus (SLE). The main objective of our study was to evaluate factors associated with cHPV infection in patients with either rheumatoid arthritis (RA) or SLE, and to determine whether SLE itself is an independent risk factor for cHPV infection. We included 670 patients (in consecutive selection) in this cross-sectional study (550 with RA and 120 with SLE). All patients were evaluated by a dermatologist; patients with cHPV infection were selected as cases (63) and the other 607 patients were selected as controls. The prevalence of cHPV infection was increased 2.8-fold in SLE patients (20%) compared with RA patients (7.1%). When comparing cases with controls, bivariate analysis showed statistically significant differences for: age, having SLE, and treatment with mycophenolate mofetil (MMF). When all of the potential risk factors identified using bivariate analysis (age, having SLE, and MMF) were included into a multivariate model, independent risk factors for cHPV infection were: having SLE (odds ratio: 2.16, 95% confidence interval: 1.04-4.48) and MMF therapy (odds ratio: 2.91, 95% confidence interval: 1.18-7.14).

Tissue biomarkers as prognostic variables of cervical cancer

The most important prognostic variables of cervical carcinoma are FIGO stage, lymph node status and clinical-pathological features of primary tumor. Recently, there has been increasing interest in the identification of biomarkers able to predict both response to treatment and survival. The aim of this review is to critically evaluate current published evidence on the ability of various tissue biomarkers to predict the clinical outcome of patients with cervical carcinoma. In particular, the paper takes into account DNA content, cell-cycle and apoptosis-regulatory proteins, epidermal growth factor receptor [EGFR], vascular endothelial growth factor [VEGF], cyclooxygenase [COX]-2, signal transducer and activator of transcription [Stat]3, human papilloma virus [HPV] status, tumor hypoxia, tumor infiltrating lymphocytes [TIL], microarray technology and microRNA (miRNA). The presence of HPV-18 genotype and an elevated VEGF expression appear to be poor prognostic factors in women with early disease treated with primary surgery, whereas the expression of EGFR, VEGF, COX-2 and tumor hypoxia may have a major impact on the survival of patients treated with definitive radiotherapy or chemoradiation. The data supporting the reliability of ΔNp73 and TAp73α as novel biomarkers of response to radiotherapy are interesting but still limited. DNA microarray technology could offer new laboratory tools for a rationale planning of treatment strategy, and miRNAs might represent new candidate targets to be investigated for both prognostic and therapeutic purposes. Moreover, the assessment of different types of TIL and their ligands in tumor biopsies could enable the identification of a subset of high-risk patients, paving the way to novel immune therapies aimed at blocking T-reg cell activity.

Dietary exposure to brominated flame retardants and abnormal Pap test results

OBJECTIVE

This study examined a possible association of dietary exposure to polybrominated biphenyls (PBBs), a brominated flame retardant, and self-reported abnormal Pap test results and cervical dysplasia as a precursor to cervical cancer.

METHODS

Women in Michigan who ingested contaminated poultry, beef, and dairy products in the early 1970s were enrolled in a population-based cohort study in Michigan. Serum PBB and serum polychlorinated biphenyl (PCB) concentrations were measured. Reproductive history and health information, including Pap test results, were self-reported by participants.

RESULTS

Of the women, 23% (223 of 956) reported an abnormal Pap test. In unadjusted analyses, self-reporting an abnormal Pap test was associated with younger age, current smoking (hazard ratio [HR] 1.61, 95% confidence interval [CI] 1.19-2.17), and longer duration of lifetime use of oral contraceptives (≥10 years; HR 1.92, 95% CI 1.21-3.06). When adjusting for PCB exposure, age at the interview, and smoking history, there was a slightly elevated risk of self-reporting an abnormal Pap test among the highly exposed women compared to women with nondetectable PBB concentrations (PBB≥13 μg/L, HR 1.23, 95% CI 0.74-2.06); however, the CI was imprecise. When breastfeeding duration after the initial PBB measurement was taken into account, there was a reduced risk of self-reporting an abnormal Pap test among the highly exposed women who breastfed for ≥12 months (HR 0.41, 95% CI 0.06-3.03; referent group: women with nondetectable PBB concentrations who did not breastfeed).

CONCLUSIONS

It remains important to evaluate the potential reproductive health consequences of this class of chemicals as well as other potential predictors of abnormal Pap tests.

Smoking habit, immune suppression, oral contraceptive use, and hormone replacement therapy use and cervical carcinogenesis: a review of the literature

High-risk human papillomaviruses (HPVs) are involved in the etiopathogenesis of cervical intraepithelial neoplasia (CIN) and cervical cancer. After taking HPV into account, smoking habit appears to be the most significant environmental risk factor, and the risk of this malignancy increases significantly with intensity and duration of smoking. Women with human immunodeficiency virus (HIV) infection experience a higher incidence of CIN and invasive cervical cancer. Among HIV+ women, the highly active antiretroviral therapy increases the regression rate of CIN, but the majority of these lesions do not regress to normal. As far as oral contraceptives (OCs), a systematic review of 28 studies found that, compared with never pill users, the relative risk (RR) of cervical cancer increased with increasing duration of OC use. The results were similar for squamous cell carcinoma and adenocarcinoma, and the RRs decreased after pill discontinuation. However, by weighing risks and benefits, the World Health Organization does not recommend any change in OC practice. There is no correlation between hormone replacement therapy and cervical cancer. Experimental data have shown that estradiol and progesterone can modulate the host immune response to HPV16. Prophylactic vaccination in conjunction with cervical screening is the best prevention strategy for cervical cancer.

Malignancies in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a prototypical systemic autoimmune disease, characterized by a wide array of symptoms and organ involvements, leading to varying disease courses and outcome, and ranging from mild to severe types. In patients with SLE, the incidence and risk of malignancy development is increased, and mostly non-Hodgkin's lymphoma (NHL), cervical cancer, as well as bronchial carcinomas occur. Besides others, the common genetic predisposition, chronic antigen stimulus, disproportional immune responses, as well as the chronic administration of immunosuppressive medications can contribute to the development of malignancies in lupus. In this review we present the molecular pathology, as well as the epidemiological and clinical aspects of malignancies in patients with SLE.
