Abstract
PURPOSE This review presents an update of the non-contraceptive health benefits of the combined oral contraceptive pill. METHODS We conducted a literature search for (review) articles that discussed the health benefits of combined oral contraceptives (COCs), in the period from 1980 to 2023. RESULTS We identified 21 subjective and/or objective health benefits of COCs related to (i) the reproductive tract, (ii) non-gynaecological benign disorders and (iii) malignancies. Reproductive tract benefits are related to menstrual bleeding(including anaemia and toxic shock syndrome), dysmenorrhoea, migraine, premenstrual syndrome (PMS), ovarian cysts, Polycystic Ovary Syndrome (PCOS), androgen related symptoms, ectopic pregnancy, hypoestrogenism, endometriosis and adenomyosis, uterine fibroids and pelvic inflammatory disease (PID). Non-gynaecological benefits are related to benign breast disease, osteoporosis, rheumatoid arthritis, multiple sclerosis, asthma and porphyria. Health benefits of COCs related to cancer are lower risks of endometrial cancer, ovarian cancer and colorectal cancer. CONCLUSIONS The use of combined oral contraceptives is accompanied with a range of health benefits, to be balanced against its side-effects and risks. Several health benefits of COCs are a reason for non-contraceptive COC prescription.

Abstract
Combined oral contraceptives are a common method of contraception and many females prefer them regardless of their medical history. The use in patients with rheumatoid and autoimmune disorders has not been extensively studied with previous reviews focusing on the safety component. This review seeks to address the effectiveness and benefits of utilizing combined oral contraceptives in females with rheumatoid arthritis (RA). Current literature regarding combined oral contraceptives was surveyed for its use in RA and two PubMed searches were conducted, yielding 202 and 142 results, respectively. Results were screened and analyzed for relevance to this review topic. Eighteen results, consisting of clinical trials, observational studies, patient cases, and meta-analyses were used in this narrative review. Historically, it was thought that females with an autoimmune disorder such as RA need to be on contraception due to the teratogenicity potential with disease-modifying therapy but no evidence exists about which type of contraception is the most effective and least interacting. Current evidence available shows no preference for types of contraception in this population, but it has been demonstrated that combination oral contraceptives may provide contraceptive benefits and have a potential for other benefits such as less disability and the prevention of disease progression. Although current evidence provides reasoning to believe combination oral contraceptives are safe and efficacious in patients with RA and may even offer additional benefits, further studies and clinical trials are needed to completely understand the role combination oral contraceptives play in this patient population.

Menopausal factors and risk of seropositive rheumatoid arthritis in postmenopausal women: a nationwide cohort study of 1.36 million women. Sci Rep 2020; 10:20793.

Abstract
In previous literature regarding development of rheumatoid arthritis (RA), female reproductive factors have been described as protective factors, risk factors, or irrelevant, leading to inconsistent results. The aim of this study was to investigate the effect of female reproductive factors on the incidence of seropositive RA. A large population-based retrospective cohort of the National Health Insurance Service data in South Korea was used. Postmenopausal women who participated in both cardiovascular and breast cancer screening in 2009 were included and followed until date of seropositive RA diagnosis, death, or December 31, 2018. Multivariable-adjusted Cox proportional hazards model was used to assess the association between reproductive factors and incident seropositive RA. Of 1,357,736 postmenopausal women, 6056 women were diagnosed with seropositive RA, and the incidence rate was 54.16 cases/100,000 person-years. Reproductive factors other than hormone replacement therapy (HRT) were not significantly associated with seropositive RA incidence. Postmenopausal women who used HRT ≥ 5 years were associated with a higher aHR of incident seropositive RA than never-users (aHR 1.25; 95% CI 1.09–1.44). Alcohol consumption less than 30 g per day (aHR 0.80; 95% CI 0.74–0.87), regular physical activity (aHR 0.90; 95% CI 0.84–0.97), diabetes mellitus (aHR 0.85; 95% CI 0.78–0.93), and cancer (aHR 0.77; 95% CI 0.64–0.92) were associated with lower risk of seropositive RA. Most female reproductive factors did not significantly affect the development of seropositive RA in postmenopausal women. Only HRT is associated with a small but significant increase in risk of seropositive RA.

Abstract
Menopause occurs naturally in women at about 50 years of age. There is a wealth of data concerning the relationship of menopause to systemic lupus erythematosus, rheumatoid arthritis, and osteoarthritis; there are limited data concerning other rheumatic diseases. Age at menopause may affect the risk and course of rheumatic diseases. Osteoporosis, an integral part of inflammatory rheumatic diseases, is made worse by menopause. Hormone replacement therapy has been studied; its effects vary depending on the disease and even different manifestations within the same disease. Cyclophosphamide can induce early menopause, but there is underlying decreased ovarian reserve in rheumatic diseases.

Oral contraceptives, breastfeeding and the risk of developing rheumatoid arthritis: results from the Swedish EIRA study. Ann Rheum Dis 2017; 76:1845-1852. [PMID: 28818831 PMCID: PMC5705848 DOI: 10.1136/annrheumdis-2017-211620] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2017] [Revised: 06/15/2017] [Accepted: 06/24/2017] [Indexed: 01/16/2023]
Abstract
OBJECTIVES To study whether oral contraceptive (OC) use or breastfeeding (BF) influence the risk of rheumatoid arthritis (RA), stratifying the cases by presence/absence of anticitrullinated protein antibodies (ACPA), and whether these factors interact with known risk factors in the development of ACPA-positive RA. METHODS Women aged ≥18 years, participants in the population-based case-control Swedish Epidemiological Investigation of RA study (2641 cases/4251 controls), completed an extensive questionnaire regarding OC, BF and potential confounders. We calculated ORs, with 95% CIs, adjusted for age, residential area, smoking and alcohol consumption. Attributable proportion due to interaction (AP) was estimated to evaluate presence of interaction. RESULTS Compared with never users, ever and past OC users had a decreased risk of ACPA-positive RA (OR=0.84 (95% CI 0.74 to 0.96); OR=0.83 (95% CI 0.73 to 0.95), respectively). No significant associations were found for ACPA-negative RA. Long duration of OC use (>7 years vs never use) decreased the risk of both ACPA-positive (p=0.0037) and ACPA-negative RA (p=0.0356).A history of long BF decreased the risk only of ACPA-positive RA in a dose-dependent manner (p=0.0086), but this trend did not remain after adjustments. A significant interaction was observed between the lack of OC use and smoking (AP=0.28 (95% CI 0.14-0.42)) on the risk of ACPA-positive RA. No interactions were found for BF. CONCLUSIONS OC decreased the risk of RA, especially ACPA-positive RA, where an interaction with smoking was observed. A long duration of OC use decreased the risk of both disease subsets. We could not confirm an association between BF and a decreased risk of either ACPA-positive or ACPA-negative RA.

Abstract
Rheumatoid arthritis (RA) is a chronic, autoimmune, inflammatory disease destroying articular cartilage and bone. The female preponderance and the influence of reproductive states in RA have long linked this disease to sexually dimorphic, reproductive hormones such as prolactin (PRL). PRL has immune-enhancing properties and increases in the circulation of some patients with RA. However, PRL also suppresses the immune system, stimulates the formation and survival of joint tissues, acquires antiangiogenic properties upon its cleavage to vasoinhibins, and protects against joint destruction and inflammation in the adjuvant-induced model of RA. This review addresses risk factors for RA linked to PRL, the effects of PRL and vasoinhibins on joint tissues, blood vessels, and immune cells, and the clinical and experimental data associating PRL with RA. This information provides important insights into the pathophysiology of RA and highlights protective actions of the PRL/vasoinhibin axis that could lead to therapeutic benefits.

Abstract
Background and objectives Epidemiological investigations of the relationship between oral contraceptives and rheumatoid arthritis (RA) risk have reported controversial results. Therefore, a meta-analysis of case-control or cohort studies was performed to evaluate the role of oral contraceptives in relation to risk of developing RA. Methods Eligible studies were identified from databases PubMed and EMBASE by searching and reviewing references. Random effect models were utilized to summarize the relative risk (RR) estimates with 95% confidence intervals (CIs). Results A total of 12 case-control studies and five cohort studies were eligible for our analysis. No statistically significant association was observed between oral contraceptives and RA risk (RR=0.88, 95% CI=0.75–1.03). In the subgroup of geographic area, a decreased risk of borderline significance was observed for oral contraceptive users in European studies (RR=0.79, 95% CI=0.62–1.01), but this association did not emerge in the North American studies group (RR=0.99, 95% CI=0.81–1.21). No evidence for publication bias was detected (P for Egger’s test =0.231). Conclusion Our results of meta-analysis do not support the hypothesis of a protective effect of oral contraceptives on the risk for RA in women.

Abstract
Autoimmune diseases are a range of diseases in which the immune response to self-antigens results in damage or dysfunction of tissues. Autoimmune diseases can be systemic or can affect specific organs or body systems. For most autoimmune diseases there is a clear sex difference in prevalence, whereby females are generally more frequently affected than males. In this review, we consider gender differences in systemic and organ-specific autoimmune diseases, and we summarize human data that outlines the prevalence of common autoimmune diseases specific to adult males and females in countries commonly surveyed. We discuss possible mechanisms for sex specific differences including gender differences in immune response and organ vulnerability, reproductive capacity including pregnancy, sex hormones, genetic predisposition, parental inheritance, and epigenetics. Evidence demonstrates that gender has a significant influence on the development of autoimmune disease. Thus, considerations of gender should be at the forefront of all studies that attempt to define mechanisms that underpin autoimmune disease.

Abstract
Multiple environmental factors including hormones, dietary factors, infections, and exposure to tobacco smoke, as well as gene-environment interactions, have been associated with increased risk for rheumatoid arthritis (RA). The growing understanding of the prolonged period before the first onset of symptoms of RA suggests that these environmental and genetic factors are likely acting to drive the development of RA-related autoimmunity long before the appearance of the first joint symptoms and clinical findings that are characteristic of RA. This article reviews these factors and interactions, especially those that have been investigated in a prospective fashion before the symptomatic onset of RA.

Abstract
Objective. To perform a meta-synthesis of the evidence for modifiable lifestyle risk factors for inflammatory polyarthritis (IP) and RA. Methods. We performed a MEDLINE literature search. Case–control and cohort studies and systematic reviews published from 1948 through February 2011 and studying modifiable risk factors for RA were retrieved. The main outcome measure was diagnosis of RA according to the standard criteria. Results. Smoking contributes up to 25% of the population burden of RA. The risk is dose related, stronger in males and especially strong for anti-citrullinated peptide antibody positive (ACPA+) RA through an interaction with the shared epitope. After smoking cessation, there is, however, a latency of up to 20 years to return to baseline risk. Other associations are less definitive; however, prospective studies suggest that dietary antioxidants and breastfeeding may be protective and that high coffee consumption may increase RA risk. An inverse association with alcohol intake (especially in smokers) and with education/social class (especially seropositive RA) and an increased risk with obesity (seronegative RA) is also noted. Conclusion. There is a need for further large-scale prospective studies with a consistent definition of RA phenotype (undifferentiated IP through to ACPA+/RF+ disease). This will ultimately afford the opportunity to evaluate preventative population strategies for RA akin to the well-established programmes for cardiovascular disease and cancer, targeting common risk factors.

Abstract
OBJECTIVE Use of oral contraceptives (OCs) may prevent the development of rheumatoid arthritis, but the influence of OC use on disease outcome is unresolved. The purpose of this study was to examine functional outcome and OC use in women with inflammatory polyarthritis (IP). METHODS The Norfolk Arthritis Register (NOAR) is an inception cohort of patients with recent-onset IP. We studied patient-reported history of OC use in 663 women who were born after 1945 and who had not used OCs during followup. OC use during followup was additionally investigated in 265 women who were <50 years old and had not undergone menopause or hysterectomy during followup. All patients were recruited to the NOAR between 1990 and 2004. Functional ability was assessed using the Health Assessment Questionnaire (HAQ), with adjustment for age at symptom onset. RESULTS The median followup was 4.9 years. In the investigation analyzing OC use before symptom onset, patients who had used OCs before symptom onset had lower HAQ scores throughout followup than patients who had not taken OCs before symptom onset (difference in score at 5-year followup -0.35; 95% confidence interval [95% CI] -0.51, -0.19). Patients who were taking OCs at baseline had lower HAQ scores over time than women who were not taking OCs at baseline but had previously done so (mean difference -0.21; 95% CI -0.40, -0.02). In the investigation analyzing OC use during followup, OC use during followup was associated with lower HAQ scores over time than no OC use during followup (mean difference -0.06; 95% CI -0.16, 0.03); however, this was only significant for women with moderate or severe functional disability at the previous assessment (mean difference -0.23; 95% CI -0.40, -0.07). Further adjustment for potential confounders and exclusion of hormone replacement therapy users had little impact. CONCLUSION OC use is generally associated with a beneficial functional outcome in IP, and use before and at symptom onset appeared to have the most consistent benefit.

Abstract
This cytometric study assesses the effects of methotrexate (MTX) on the expanded CD4+ lymphocyte population in active and nonactive rheumatoid arthritis (RA) patients. In the active patients, MTX was found to reduce the predominant CD4+ CD28+ subpopulation (by 30%), and the minor subpopulation of CD4+ CD28- (by 34%). The incidence of CD25 phenotype was downregulated by 15%. These reductions can be attributed to immunosuppression through apoptosis, which was demonstrated by MTX-induced fluorescein diacetate (FDA) hyperpolarization (an established indicator of early apoptosis). In contrast, in nonactive RA patients, the major CD4+ CD28+ subpopulation of small lymphocytes appeared to be activated by MTX, subsequently transforming into a major hyperblast population, whereas the minor CD4+ CD28- subpopulation was not affected by MTX treatment. The activation by MTX in this group of patients is evidenced by MTX-induced FDA depolarization (an indicator of early activation). Thus, MTX immunosuppressive effect on CD4+ subsets was found in active patients, whereas immunostimulation by MTX was shown in nonactive patients. The found discriminative effect of MTX may suggest a higher effectiveness of low-dose MTX therapy in active RA patients.

Abstract
BACKGROUND The geographic variation in rheumatoid arthritis (RA) incidence in the United States is unknown. METHODS We studied residential region from January 1, 1921, to May 31, 1976, and RA risk in a prospective cohort of women, the Nurses' Health Study. Information on state of residence was collected at baseline in 1976 (when participants were aged 30-55 years) and on state of residence at birth, at age 15 years, and at age 30 years in 1992. Among 83,546 participants reporting residence for all 4 time points, 706 incident RA cases from June 1, 1976, to May 31, 2004, were confirmed by screening questionnaire and record review for American College of Rheumatology criteria. Residential region was classified as West, Midwest, mid-Atlantic, New England, and Southeast. Multivariate Cox proportional hazards regression models were used to assess relationships between region and RA risk, adjusting for age, smoking, body mass index, parity, breastfeeding, postmenopausal status, postmenopausal hormone use, father's occupation, race, and physical activity. Analyses were performed in participants who lived in the same regions, or moved, over time. RESULTS Compared with those in the West, women in New England had a 37% to 45% elevated risk of RA in multivariate models at each time point (eg, state of residence in 1976: rate ratio [RR], 1.42; 95% confidence interval [CI], 1.10-1.82). In analyses of women who lived in the same region at birth, age 15 years, and age 30 years, living in the Midwest was associated with greater risk (RR, 1.47; 95% CI, 1.05-2.05), as was living in New England (RR, 1.40; 95% CI, 0.98-2.00). Compared with living in the West at birth, age 15 years, and age 30 years, RA risk was higher in the East. CONCLUSIONS In this large cohort of US women, significant geographic variation in incident RA existed after controlling for confounders. Potential explanations include regional variation in behavioral factors, climate, environmental exposures, RA diagnosis, and genetic factors.

Abstract
The combined role of genes, environment and immunity in the development of rheumatoid arthritis (RA) has been the subject of recent investigations. New data support a gene-environment interaction between smoking and the MHC class II HLA-DRB1 shared epitope (SE) genes in anti-citrulline antibody (anti-CP(+)) RA but not in anti-CP(-) disease. These data from genetic epidemiology, together with information on citrullination in the lungs of smokers, have prompted the formulation of a new etiological hypothesis for anti-CP(+) RA, suggesting that smoking in the context of HLA-DR SE might trigger immunity to citrulline-modified proteins and that this immunity, after several years, might cause arthritis.

Abstract
OBJECTIVE To explore the contribution of female hormonal factors occurring prior to the onset of rheumatoid arthritis (RA), such as age at menarche, parity, age at first birth, breast-feeding, use of oral contraceptives (OCs), irregular menstrual cycles, and postmenopausal hormone (PMH) use, to the subsequent development of RA in a large female cohort. METHODS We studied female reproductive and hormonal risk factors for RA in a cohort of 121,700 women enrolled in the longitudinal Nurses' Health Study. The diagnosis of incident RA (between 1976 and 2002) in 674 women was confirmed by a connective tissue disease screening questionnaire and blinded medical record review for American College of Rheumatology criteria. Sixty percent of the patients with RA were rheumatoid factor positive. The relationship between potential risk factors, including age, age at menarche, parity, age at first birth, total lifetime history of breast-feeding, use of OCs, and irregular menstrual cycles and the multivariate-adjusted risk of RA was estimated using Cox proportional hazards models. RESULTS Using a multivariate model that adjusted for age, body mass index, smoking, parity, and other hormonal factors, we observed a strong trend for decreasing risk of RA with increasing duration of breast-feeding (P for trend = 0.001). For women who breast-fed (compared with parous women who did not breast-feed), the risk ratios (RRs) and 95% confidence intervals (95% CIs) were as follows: breast-feeding for < or =3 total months, RR 1.0 (95% confidence interval [95% CI] 0.8-1.2); for 4-11 total months, RR 0.9 (95% CI 0.7-1.1); for 12-23 total months, RR 0.8 (95% CI 0.6-1.0); and for > or =24 total months, RR 0.5 (95% CI 0.3-0.8). Very irregular menstrual cycles were associated with an increased risk of RA (RR 1.4, 95% CI 1.0-2.0). Age at menarche < or =10 years was associated with an increased risk of seropositive RA (RR 1.6, 95% CI 1.1-2.4) but not significantly associated with risk of RA. Parity, total number of children, age at first birth, and OC use were not associated with an increased risk of RA in this cohort. CONCLUSION In this large cohort, breast-feeding for >12 months was inversely related to the development of RA. This apparent effect was dose-dependent, with a significant trend toward lower risk with longer duration of breast-feeding. Irregular menstrual cycles and earlier age at menarche increased the risk of RA. Other reproductive hormonal factors were not associated with RA risk.

Abstract
Rheumatoid arthritis (RA) is a chronic, generally progressive autoimmune disease that causes functional disability, significant pain and joint destruction, and leads to premature mortality. It is estimated to affect between 0.5 and 1.0% of the adult population worldwide, increases in prevalence with age and affects more women than men. The magnitude of the severe long-term economic consequences of RA has been underestimated in the past. Most patients with the disease require continuous treatment to retard or stop progression and to control disease flares. Many also require surgery, such as total hip or knee replacement. In addition to these direct costs, work disability leads to reduced productivity and early retirement, and as a result, substantial indirect costs. The individual and his or her family must cope with the feeling of loss of contribution to society combined with redefined social roles, and the effects of pain, fatigue, low self-esteem, mental distress and depression. A number of countries in North America and Europe have reported a decline in the incidence of RA in recent years, although geographical differences remain that may be associated with genetic, environmental or cultural factors. Nevertheless, patients with RA have not shared the improvements in survival rates seen with other diseases over the last 40 years, and have a mean reduction in life expectancy of between 5 and 10 years. Disease severity, activity and disability are strongly linked to premature mortality in patients with RA. The high direct and indirect costs associated with RA, together with the substantial morbidity and mortality affecting millions of people worldwide, underline the potential benefits of improved treatments for this chronic disease to patients, their families and society.

Abstract
OBJECTIVE Endogenous and exogenous reproductive hormones have been associated with rheumatoid arthritis (RA) in women, but data are inconsistent and no studies have assessed RA risk factors exclusively in elderly women. METHODS The authors examined the association between reproductive factors, exogenous hormone exposure, and RA in a prospective cohort study of 31,336 Iowa women who were aged 55 to 69 years at cohort baseline in 1986. RESULTS During 11 years of follow-up, 158 incident cases of RA were identified and validated. Age at last pregnancy (P trend =.01) and age at menopause (P trend =.03) were inversely associated with RA, whereas a history of polycystic ovary syndrome (relative risk [RR], 2.58; 95% confidence interval [CI], 1.06 to 6.30), endometriosis (RR, 1.72; 95% CI, 0.93 to 3.18), and former use of hormone replacement therapy (RR, 1.47; 95% CI, 1.04 to 2.06) were positively associated with RA. In multivariate analysis models, a history of polycystic ovary syndrome remained the most consistent predictor of RA, whereas the RRs for other factors attenuated. CONCLUSION Few reproductive factors showed a strong or statistically significant association with RA in elderly women. The association of polycystic ovary syndrome may be indicative of perturbations of endocrine-immune activity that may influence the development of RA. This prospective cohort study adds to the understanding of the potential contribution of hormonal factors to the cause of RA in older women.

Abstract
The objectives of this study were to test the in vitro response of healthy non-activated, activated, and rheumatoid arthritis (RA) lymphocytes to methotrexate (MTX), and design an in vitro model for predicting the efficiency of MTX treatment for RA patients. Considering the RA profile of clonal-expanded CD4(+) T cells, phytohemagglutinin-activated mononuclear cells taken from healthy donors were incubated with different concentrations of MTX. The MTX-immunosuppressive effect was tested by fluorescence intensity measurements, including PI assay and annexin V assay. For simple detection, we used the Individual Cell Scanner (IC-S), which enables the measurement of early events in individual cells. Healthy mononuclear cells (MNC), and MNC derived from RA patients, were tested by the IC-S while utilizing fluorescence polarization (FP) measurements of fluorescein diacetate (FDA) as an established marker of activation or suppression. In healthy activated MNC, we found that MTX, through its early incubation period, interferes with the activation signal obtained by PHA and exerts an apoptotic signal, which is noted by increases in the FP. Comparing our model to six long-standing RA patients and five newly-diagnosed patients revealed significant differences in the FP measurements, including fluorescence depolarization as an early established measurement of lymphocyte activation, and hyperpolarization as a measurement of an early immunosuppressive effect. We conclude that MTX, an effective therapy for RA patients, could easily be tested by fluorescence polarization measurements of FDA before (or during) clinical use in order to predict its efficiency on a specific RA patient. Moreover, the FP measurements can be used for the diagnosis, and making timing and dosage decisions.

Abstract
OBJECTIVES To predict the long-term outcome of rheumatoid arthritis (RA) with respect to radiographic damage, disability, and disease course using baseline variables, and to construct decision trees identifying patients on an individual level at the extremes of the outcome spectrum of these 3 dimensions. METHODS The 12-year outcome of 112 female RA patients from a prospective inception cohort was assessed by measuring the tertiles of radiographic damage (measured by the modified Sharp/van der Heijde method, SHS), disability (measured by the Health Assessment Questionnaire, HAQ), and severe disease course as defined by patients with either the 33% highest cumulative disease activity (area under the curve of all observed disease activity scores) or the highest tertile of radiographic damage. Patients in the lowest (mild) and highest tertile (severe) of each outcome measure were identified. All baseline parameters known to be associated with each outcome (demographic and socioeconomic parameters; disease duration; disease activity measures; laboratory measures including rheumatoid factor, HLA typing, percentage agalactosyl IgG, functional and radiographic measures) were entered into cross-validated stepwise logistic regression models to find the best predictive combination of baseline parameters for each of the outcomes. Using the results of the logistic regression models, simple decision trees were constructed to categorize patients at an individual level in a particular prognostic group. RESULTS After 12 years, the lowest and highest tertiles were, respectively, 42.3 and 189 for the SHS and 0.37 and 1.25 for the HAQ. Fifty-five patients had a severe disease course. Mild and severe radiographic damage could be predicted with an accuracy of 90% and 85%, respectively. Mild and severe HAQ could be predicted with an accuracy of 90% and 84%, respectively, and severe disease course with an accuracy of 81%. The baseline variables found to be predictive of all 3 outcome measures were very similar and consisted of combinations of the following baseline parameters: swollen joint count (SJC), Ritchie score, rheumatoid factor (RF), the presence of erosions, and the HAQ score. Additional knowledge of the HLA typing hardly improved the accuracy of the prediction. To predict outcome at the individual level, simple decision trees were constructed using the RF, HAQ, SJC, and presence of erosions at baseline. CONCLUSION The present study shows that prediction of outcome in long-term RA is possible and can be done using widely available baseline parameters.

Abstract
BACKGROUND Oral contraceptives (OC) and pregnancy are known to have an influence on the risk of onset of rheumatoid arthritis (RA). Pregnancy itself has beneficial effects on the activity of the disease, with relapses post partum. It is not known, however, whether OC and pregnancies influence the ultimate outcome of RA. OBJECTIVES To explore whether OC use and pregnancies influence the 12 year outcome in RA as measured by radiological damage and disability. METHODS In a prospective inception cohort of 132 female patients with recent RA according to the 1987 American College of Rheumatology criteria-a cohort initially gathered to study the association between hormonal factors and the onset of RA-outcome was assessed in a follow up after 12 years. The outcome was evaluated in 112 (85%) women by the radiological damage of hands and feet as measured with the Sharp score modification van der Heijde (SHS), the damage of the large joints measured with the Larsen score (LS) of large joints (0-60), and the disability measured with the Health Assessment Questionnaire (HAQ). The median values of each outcome variable were calculated for several subgroups of patients stratified for OC use and pregnancies before and after onset of the disease and the tertiles of the total number of months of OC use and of pregnancies. The association of OC use and pregnancies before and after onset of the disease with the outcome variables was calculated using Spearman's rank correlation (r(s)). The combined influence of OC use and pregnancies on the SHS, LS, and HAQ at 12 years was estimated using ordinal polytomous logistic regression. RESULTS The median values of the SHS, LS, and HAQ showed a trend towards less radiological joint damage and less disability in women with long term OC use and multiple pregnancies. This difference, however, was not significant, except for the HAQ score in women with three or more pregnancies in life. There was no association between pregnancies, however defined, and any parameter of RA outcome after 12 years (maximum r(s)=-0.10). The only significant correlation was found between OC use before symptom onset and the LS (r(s)=-0.22, p<0.05). The combination of hormonal variables explained no more than a maximum of 3% of the variance of the 12 year outcome as measured by the SHS. CONCLUSION OC use and pregnancy do not significantly influence outcome in long term RA. There is, however, a trend for patients with multiple pregnancies and long term OC use to have less radiographic joint damage and a better functional level.

Abstract
PURPOSE Primary biliary cirrhosis is an autoimmune disease with female predominance that leads to liver failure. The goal of this study was to identify reproductive risk factors associated with this disease. METHODS We compared 182 cases of PBC with 225 age- and sex-matched friend controls to examine the role of reproductive factors. The survey instrument was developed using standardized questions obtained from the National Health and Nutrition Examination Survey (NHANES) III. RESULTS A total of 126/182 cases (69%) and 141/225 (62.6%) friend controls responded to the survey. More cases than controls reported ever having genitourinary infection [adjusted odds ratio (OR) = 2.12, 95% confidence interval (CI) 1.01, 4.42] among those without a personal or family history of autoimmune disease. The most notable finding was that cases reported significantly more pregnancies than controls (p = 0.008). The adjusted OR for each additional pregnancy among those without a personal or family history of autoimmune disease was 1.40 (95% CI 1.14, 1.7). More controls (24.4%) than cases (16.0%) were nulliparous. Cases reported having five or more children (16.0%) with double the frequency of controls (8.2%). CONCLUSIONS The association reported herein, between primary biliary cirrhosis and gravidity, is particularly significant because of the overwhelming female predominance.

Abstract
OBJECTIVE Constitutive differences between individuals in cytokine production may determine the variation in the course of inflammatory arthritis. METHODS The association between interleukin 10 (IL-10) production and joint destruction was studied by comparing IL-10 mRNA content in synovial biopsies from seven patients with destructive joint disease and six patients with non-destructive joint disease. The IL-10 mRNA content was 0.4 +/- 0.6 arbitrary units in erosive joints compared with 2.3 +/- 1.2 arbitrary units in non-erosive joints (P: < 0.03, Mann-Whitney U:-test). As this difference suggested that IL-10 production was associated with joint destruction, we tested whether the IL-10 locus determined the extent of joint damage. RESULTS Innate differences in IL-10 production are locus-dependent. In line with these data, we showed that innate differences in IL-10 protein production were also present as differences in IL-10 mRNA levels. We tested if polymorphisms in the promoter of IL-10 were associated with the extent of joint damage. DISCUSSION In a cohort study of female rheumatoid arthritis patients followed for 12 yr, the extent of joint destruction differed significantly between patients with different IL-10 genotypes. In patients with the -1082AA genotype who were studied prospectively, the mean increase in radiographic damage score (modified Sharp score of X-rays of hands and feet) during the first 6 yr was 9 +/- 9 per yr vs 19 +/- 16 per yr for patients with the genotype -1082GG (P: < 0.02). In line with these data, cultures of endotoxin-stimulated whole blood from 158 donors showed that the presence of the allele associated with less joint destruction correlated with slightly higher IL-10 production. CONCLUSIONS Both the immunogenetic and the synovial biopsies suggest that a variation in IL-10 production is associated with joint destruction.

Abstract
A role for sex steroids in the pathogenesis of AS is suggested by the male predominance, the peak age of onset in young adults, the increased number of first manifestations and flares after pregnancy, and the fact that sex steroids may modulate immune functions. There is a theoretic possibility that (normal levels of) androgens are indeed relevant in the male sex skew of AS. It has been reported that men with AS have higher than normal androgen levels; however, the evidence that serum testosterone levels are elevated in patients with AS is not robust. Elevated DHEAS and 17 alpha-hydroxyprogesterone levels have been reported in male AS patients; these may be secondary to inflammation and stress but may theoretically also be causally related to AS. These elevations might result from a partial late onset 11 beta- or 21-hydroxylase deficiency. Current data on sex steroid hormones provide no straightforward explanation for the male predominance in AS. It is fair to say that present data in patients with long-standing AS are too limited to suggest a role for androgens in the perpetuation of the disease, but a role in the initiation and the early stages of AS cannot be excluded. Such information can only be obtained from prospective studies. Cross-sectional studies cannot clearly distinguish causal relation from secondary disease effects, because blood sampling to test these hypotheses only takes place many years after the onset of disease. The impact of sex steroids on these features of AS is still unresolved. There is as yet no rationale for the use of medication that modifies sex steroid hormones in the management of AS. Alternative explanations for the higher male prevalence of AS may be found in the different chromosomal configuration and body composition of men and women.

Abstract
A number of hormonal abnormalities are present in RA patients. A major theme of these abnormalities seems to be that deficiencies in the production or action of gonadal (estrogens and androgens) and adrenal (corticosteroids and DHEA) hormones may be involved in regulating the onset, severity, and progression of RA. Differences in RA incidence and activity in the pregnant and postpartum periods provide the strongest support for this view. Hormonal changes during these periods clearly have the potential to exert profound effects on RA incidence and activity. The effect of pregnancy on RA activity is actually greater than the effect of some of the newer therapeutic agents. The striking increase in corticosteroids, estrogen, and progesterone during pregnancy may suppress RA onset or activity through the regulation of production or action of cytokines such as TNF alpha, IL-1, IL-6, IL-12, and IL-10. The relative adrenal- and gonadal-deficient environment of the postpartum period further supports the view that hormonal deficiencies predispose to the development or increased activity of RA. These observations justify the search for hormonal abnormalities in RA patients outside the pregnancy and postpartum periods. In particular, further studies on the period before the onset of disease are needed. Additional evidence does exist that a functional abnormality in the adrenal glands in RA patients results in dysregulation of corticosteroid and DHEA production. These abnormalities seem to be linked to aging and disease activity. It is still not established whether these abnormalities are primary or secondary, although data indicating adrenal hypofunction before the development of RA or within the first year of disease activity suggest a primary abnormality. Several hormonal abnormalities seem to be restricted by gender and age, particularly around perimenopause and menopause. These age- and gender-influenced effects may be the cause of some of the contradictory data reviewed here. Studies in the future should make greater efforts to segregate study populations by age, gender, and reproductive status. The identification of the specific hormonal abnormalities and patient populations that are at risk is important, because these factors may allow new therapeutic approaches that are less toxic than current regimens.

Abstract
Molecular biology has had a major impact on our concepts of the immune system and its relation to neuroendocrine axes, in particular, the adrenal, gonadal, and thyroid axes. It is now well established that not only are the biosynthetic and catabolic pathways of glucocorticoids and sex hormones (estrogen, progesterone, and testosterone) closely related but that the receptors for these hormones are part of a supergene family of receptors which include (in addition to these hormone receptors) the mineralocorticoid receptor, thyroid hormone receptor, retinoic acid receptors, and vitamin D receptors. This suggests a complex network of steroid hormones and receptors for the control and integration of a multitude of physiologic functions at a systemic level. The immune system seems to be tightly integrated into this homeostatic neuroendocrine regulatory network. The neurophysiologic and biochemical events that promote successful adaptation during stressful situations are now identified for illnesses that seem to occur as a result of or are associated with dysregulation of the stress response. One difficulty in interpreting the mechanisms of HPA axis dysfunction in autoimmune-inflammatory syndromes arises from the plasticity of the hormonal systems involved. Levels of hormones produced and receptors reset rapidly with changes in the hormonal milieu (deficiency or excess) and have likely changed during the course of the chronic immune disorder. This, in turn, is further confounded by the pleomorphic natural history of most autoimmune-inflammatory diseases such as SS. The levels of sex hormones and their receptors are tightly linked to HPA axis function. It may be that significant changes in the estrogen-to-androgen ratio or the ratio of their receptors alter the activity of steroid-sensitive cells such as the individual immune cells or epithelial cells, thus providing a means for endocrine regulation of the immune response in SS. Studies in the closely related disorder RA support this hypothesis. Taken together, adrenal and gonadal steroid hormone deficiency plus elevated PRL levels probably greatly facilitate cellular immunity in SS patients. This hypothesis in SS is supported by a growing body of data indicating that RA develops as a consequence of a deficiency in adrenal and gonadal steroid hormone production. It is noteworthy that the findings in female SS patients indicated a central deficiency in all three neuroendocrine axes: adrenal, gonadal, and thyroid. At present, it is not clear if any one system plays a primary role in the expression of the disease. Rather, it is likely that the net effect involves the synergistic and antagonistic effects of multiple hormones, making the specific effects of individual hormones difficult to discern.

Abstract
OBJECTIVE To describe the extent of radiographic damage of large joints in long-term rheumatoid arthritis (RA) and its relationship to small joint involvement and physical function. METHODS After 12 yr of follow-up, radiographs of all large joints (Larsen large joint score 0-60) of 105 recent RA patients were assessed. Correlations were evaluated between the Larsen large joint score and radiographic damage of the hands and feet as measured by the van der Heijde modification of the Sharp score (SHS) and the health assessment questionnaire (HAQ). We determined the relative contributions of radiographic damage of small and large joints, disease activity and psychological function to the HAQ. RESULTS The median Larsen large joint score was 3. In 54% of the patients at least one large joint was erosive. The correlation of the Larsen score with the SHS and HAQ scores was 0.76 and 0.60, respectively. Disease activity and radiographic damage of the large joints were the major determinants of the HAQ score. CONCLUSION Large joint involvement after 12 yr of follow-up is extensive and is associated with functional disability. Large joint involvement is closely associated with small joint involvement.

Abstract
Pharmacists should be aware of gender-based differences and menstrual cycle-related changes in six diseases: asthma, arthritis, migraine, diabetes, depression, and epilepsy. In general, women report symptoms of physical illness at higher rates, visit physicians more frequently, and make greater use of other health care services than men. Whereas reasons for these gender differences are not fully clear, a combination of biologic, physiologic, social, behavioral, psychologic, and cultural factors most likely contributes. A significant percentage of women with asthma, arthritis, migraine, diabetes, depression, or epilepsy experience worsening of their disease premenstrually. The mechanism is unknown, but is speculated to be multifactorial because of many endogenous and exogenous modulators and mediators of each disease. As part of general therapy for cycle-related exacerbations of any one of these disorders, patients should be encouraged to use a menstrual calendar to track signs and symptoms for two to three cycles; if cyclic trends are identified, the women should anticipate exacerbations and avoid triggering factors. Cyclic modulation with pharmacotherapy may be attempted. If unsuccessful, a trial of medical ovulation suppression with a gonadotropin-releasing hormone (GnRH) analog may be warranted. If that is successful, continuous therapy with a GnRH analog and steroid add-back therapy or less expensive alternatives may be effective. If pharmacotherapy is impractical, hysterectomy and bilateral oophorectomy with estrogen replacement therapy is a last resort. Gender differences and menstrual cycle-related changes are important areas for clinical and mechanistic research.

Abstract
OBJECTIVE To investigate the evolution of functional capacity, disease activity, and joint destruction over time in a 12-year prospective cohort of rheumatoid arthritis (RA) patients, and to study the relative contribution of disease activity and joint destruction to the loss of functional capacity. METHODS One hundred thirty-two female patients with recent-onset RA were assessed at 0, 3, 6, and 12 years of followup for functional capacity (Health Assessment Questionnaire [HAQ] score), disease activity (Disease Activity Score [DAS]), and joint destruction (Sharp score of radiologic damage). RESULTS The Sharp score deteriorated steadily over time, while the HAQ score and DAS showed a variable course. The DAS correlated strongly with the HAQ score throughout the disease course. The correlation between the Sharp score and the HAQ score was weak at study start, but became strong after 12 years. After 12 years of followup, disease activity was the main determinant of the HAQ score when entered in a multivariate analysis. CONCLUSION Functional capacity is strongly influenced by disease activity throughout the course of RA. Even in longstanding RA, disease activity proves to be the main determinant of the HAQ score for functional capacity.

Abstract
OBJECTIVES Rheumatoid arthritis (RA) is an autoimmune disease that occurs more commonly in women and frequently onsets in women of childbearing age. Pregnancy often causes disease remission, with a subsequent flare postpartum. Nulliparity may be a risk factor for RA, but the literature does not consistently report this finding. There may be a production of antibodies in women with RA that could lead to infertility, and subsequent nulliparity, but this has not been proved. We wanted to determine whether there was a relationship between nulliparity, infertility, oral contraceptive use, and adverse pregnancy outcome in women with newly diagnosed RA. METHODS Through a case control study, using a mailed questionnaire, we compared the fertility and pregnancy outcome histories of 34 women between the ages of 19 and 44 years with recent-onset RA with 68 healthy controls matched for age and marital status. The response rate was 97%. A review of the literature also was performed to study the associations between RA and infertility and nulliparity, using Medline searching key references. RESULTS We found no association between infertility and the onset of RA. Seventy-one percent of women with RA and 68% of controls had been pregnant. There was a trend toward increased nulliparity in these patients, but the result was not statistically significant (odds ratio [OR], 1.4; P<.6). There were no differences in the number of children (2.6 v. 2.7; P<.6) and parity outcomes in the two groups. Age at first pregnancy was younger in the women with RA (22.6 v. 25.5 years; P<.008), but the education level was higher in the controls (P<.0001), which may explain these differences. Oral contraceptive use was lower in the RA women, but more RA women had long-term use (greater than or equal to 5 years), and neither result was statistically significant. Literature review shows that at best, there are weak negative associations between current estrogen use and RA, and no association with nulliparity and infertility. CONCLUSIONS It appears that infertility, the number of pregnancies, and pregnancy outcome are not strongly associated with the risk of developing RA in women of childbearing age. However, in this study there may have been selection biases in the women with RA and the controls that differentially could have affected their reproductive outcomes. Thus, a true association could have been missed. Most other published studies find no association between nulliparity and RA.

Abstract
OBJECTIVE To examine a range of demographic, social, and clinical risk factors for the development of rheumatoid arthritis (RA). METHODS Population-based case-control study in Norfolk, England, involving adult patients, ages 18-70, with an inflammatory polyarthritis of <12 months' duration who were recruited from the Norfolk Arthritis Register. Controls, matched for sex and date of birth, were selected from the primary care register of the Norwich Health Authority. Both cases and controls completed identical self-administered questionnaires. Matched analysis of the 165 case-control sets was conducted for the whole group and for the subset in which the cases satisfied the 1987 American College of Rheumatology criteria for RA. RESULTS The controls were of higher socioeconomic status than the cases. This was probably due to response bias. Having a body mass index > or =30 was associated with an adjusted odds ratio (OR) of 3.74 for developing RA (95% confidence interval [95% CI] 1.14-12.27). RA was also associated with a history of blood transfusion (OR 4.83, 95% CI 1.29-18.07). Even after correcting for social class, a history of having ever smoked was associated with a higher risk of developing RA (OR 1.66, 95% CI 0.95-3.06). There was no difference between cases and controls in previous exposure to childhood infections, certain surgical procedures, or reproductive history variables. CONCLUSION RA has a number of potential environmental triggers, including smoking, obesity, and blood transfusion.

Abstract
OBJECTIVE The possibility that oral contraceptives offer a protective effect against the development of rheumatoid arthritis is still contentious. Of the 17 studies investigating this association, 11 have found a protective effect, and 6 have not. These differences are probably attributable to either selection or information biases in a subset of studies, although the exact reason is unknown. To overcome the methodological problems inherent in the design of previous studies, we have conducted a population-based case-control study. METHODS Women who were incident cases of inflammatory polyarthritis, defined as swelling of at least two joint areas lasting at least 4 weeks, were recruited directly from primary care and compared with age-matched women from the same population. RESULTS Cases and controls reported a similar level of "ever use" of oral contraceptives, adjusted odds ratio = 0.88 (95% confidence interval, 0.47, 1.64). The cases were, however, less likely to report using oral contraceptives at the time of onset, adjusted odds ratio = 0.22 (95% confidence interval, 0.06, 0.85). Similar results were observed for cases who satisfied the criteria for rheumatoid arthritis and cases who did not. CONCLUSION These results indicate that only current oral contraceptive use protects against the development of inflammatory polyarthritis.

Abstract
Modulation of the immune network through the hormonal system is an exciting emerging concept. It results from a decade of experimental research obtained on rodents. Unfortunately, the therapeutic response on NZB/NZW F1 mice with murine lupus or in adjuvant induced arthritis are not transferable to man. This new field opens new therapeutic perspectives with well known and relatively safe drugs (hormone agonists, antagonists or inhibitors of hormonal secretion). Today we lack controlled, randomized clinical studies, with long-term follow-up. We also need to identify the subgroup of patients who could benefit from hormonal immunomodulation (sex, basal hormonal status, menopausal status for women, disease activity).

Abstract
The effects of estradiol benzoate (EB) on the development of anti-CII antibodies and their pathogenic potential were studied during the progress of established CIA in the rat. CIA was induced in mature female Lewis rats by two subcutaneous inoculations containing bovine native CII (BCIIn), emulsified in Freund's incomplete adjuvant. Clinical arthritis fully developed by day 18 and then EB (1 mg/kg body wt per day, diluted in corn oil (CO)) was administered intramuscularly every second day thereafter. Antibodies binding four different CIIs (bovine or rat, either native or heat-denatured) were detected in sera and joint tissue extracts by means of solid-phase ELISA. Pharmacological doses of EB (>0.2 mg/kg body wt per day) caused significant remission of established CIA 5-7 days after treatment, and selectively suppressed the production of antibodies specific for denatured CII. To evaluate the arthritogenic potential of circulating anti-CIId IgG, transfer experiments were performed. IgG anti-CIIn, purified from EB-treated CIA rats, was not arthritogenic, whereas IgG anti-denatured (CIId), purified from CO-treated CIA rats, caused severe passive arthritis. Furthermore, pretreatment with rat CIId protected against subsequent induction of CIA, and this protection was associated with suppressed antibody production against CIId. Collectively, our results indicate that antibodies specific for CIId are involved in the pathogenesis of CIA, and that oestrogen-related remission of clinical arthritis may by caused by a selective suppression of antibodies produced against degraded/denatured CII.

Abstract
OBJECTIVE To investigate the influence of breast feeding, use of the oral contraceptive pill (OCP), and parity on rheumatoid arthritis (RA). METHODS One hundred and seventy six women with RA were compared with 145 control subjects; all had at least one child. RA patients were classified as having severe (n = 82) or mild disease (n = 89) according to clinical joint evaluation, radiological score, biological inflammation, and the presence of HLA-DR1 or -DR4 alleles. RESULTS The mean age of RA patients was 58 years, and the mean age at the time of diagnosis of RA was 46 years. The mean time between onset of RA and the first birth was 23.6 (SD 3.8) years. The OCP user rates were 33% in the RA group and 47.6% in the control group (p < 0.02). OCP use was related to the mother's year of birth. The relative risk for developing RA was 0.598 (95% confidence interval (CI) 0.33 to 1.1) in women who had used OCP for more than five years compared with those who had never used OCPs. In contrast, the age at which the first pregnancy occurred, the number of children breast fed, and the duration of breast feeding were comparable in RA patients and healthy subjects. Among the RA patients, parity, duration of breast feeding, and the number of breast fed children were significantly increased in those with severe disease. Having more than three children increased the risk of developing severe disease 4.8-fold when adjusted for age and OCP use. Forty six percent of women with severe RA had a history of breast feeding duration greater than six months before disease onset, compared with 26% of patients with mild disease (p < 0.008). Having more than three breast fed children increased the risk of poor disease prognosis 3.7-fold. In contrast, OCP use had a protective role in the course of RA (44% of RA patients with mild disease were OCP users, compared with 21.7% of those with severe RA; p < 0.001). Among those using OCP for more than five years, the relative risk of developing severe disease was 0.1 (95% CI 0.01 to 0.6), after adjustment for age, parity, and breast feeding. CONCLUSION Our results suggest that parity, and to a lesser extent breast feeding, before RA onset worsened RA prognosis, whereas OCP use had a protective role. Prolactin and oestrogen may have a role in these effects.

Abstract
Autoimmune arthritis was induced after a single injection of the non-immunogenic adjuvant (avridine) or with autologous rat type II collagen. Females of two different rat strains, DA and LEW, were found to be more susceptible than males. To investigate further the mechanisms behind the female preponderance, we selected the avridine induced arthritis model. This is known to be a chronic joint-specific disease which is T-cell dependent and associated with MHC genes and, therefore, is an appropriate model for rheumatoid arthritis. To address the possibility of sex chromosome involvement, reciprocal F1 hybrids were produced. Female (DAxLEW)F1 rats were found to be more prone to arthritis than their male counterparts. This difference could be explained, at least partly, by the influence of sex chromosomes since reciprocal (LEWxDA)F1 rats showed no sex linkage. However, the sex linkage was more pronounced in normal rats when compared to castrated (DAxLEW)F1 rats indicating a role for sex hormones in conjunction with the sex chromosome-linked effect. Both oestrogen and testosterone had a suppressive effect on the development of arthritis. The findings presented here suggest the presence of a sex chromosome gene, which mediates its function only in the presence of sex hormones and is associated with a female preponderance for development of arthritis.

Abstract
OBJECTIVE To investigate the impact of sociodemographic factors on the outcome of rheumatoid arthritis (RA). METHODS A group of 138 women with RA of recent onset and a mean duration of follow up of 5.8 years was studied. Additional information on sociodemographic variables at disease onset (level of formal education, marital status and employment status) was related to the initial disease severity and various outcome measures. RESULTS Patients with lower levels of education showed a trend towards a worse outcome, according to Health Assessment Questionnaire (HAQ) score, erosion score and the patient's and physician's assessment of outcome at the last visit. However, we also found a trend towards an association between lower levels of education and more severe disease at onset, as measured by HAQ score, erosion score and the number of painful and swollen joints. The association between lower levels of education and poorer outcome of RA was weakened after correction for the initial disease severity. Results of other sociodemographic variables were equivocal. CONCLUSIONS Differences in severity of RA between patients with different levels of education develop or are present in the early stages of the disease.

Abstract
We have earlier described a chronic relapsing experimental autoimmune encephalomyelitis (EAE) in B10.RIII mice induced with a peptide of myelin basic protein (MBP), mimicking the course of multiple sclerosis in man. We now show that estrogens ameliorate chronic EAE. Castration of female mice led to an earlier disease onset (day 9 +/- 2 postimmunization (p.i.) in castrated mice vs. day 16 +/- 4 p.i. in normal mice). Long-term treatment with high levels of 17 beta-estradiol (E2) given as Silastic implants led to a dramatically delayed onset of disease in both castrated and normal female mice (mean onset day was day 39 +/- 14 and day 50 +/- 3, respectively). Treatment of castrated females by injections of E2, at a concentration which induces the serum levels seen at late stage pregnancy, delayed the onset approximately 1 week (mean onset 21 +/- 8). In contrast, treatment with estriol (E3), which was also given at doses corresponding to those levels seen during pregnancy, delayed the disease onset for a longer time (mean onset day 31 +/- 5). Five times higher doses of E2, compared with those seen during pregnancy, were required to obtain similar effects as the low E3 dose. The same mouse strain (B10.RIII) is also susceptible to induction of collagen-induced arthritis (CIA). We show here that also CIA is suppressed by the same treatments with E2 and E3, suggesting that similar estrogen-mediated mechanisms may operate to suppress these T-cell-dependent autoimmune disease models.

Abstract
The incidence of rheumatoid arthritis (RA) was estimated in the Lorraine district, eastern France, over the period 1986-1989. Cases were identified from in- and outpatients at the district Rheumatology Hospital Centre, private rheumatologists, general practitioners and by regional media announcements. Supplementary cases resident in the area were sought by extending the procedure to adjacent districts. The population count was obtained from the national Census. An overall age-adjusted incidence rate of 8.8/100,000 was found using the 1987 ACR criteria (12.7/100,000 in females, 4.7/100,000 in males; sex ratio = 2.65) and 9.5/100,000 using the 1958 ARA criteria (definite and classic RA). These rates were compared, using the same standard population, with the age-adjusted incidence rates in other incidence studies mainly conducted in Caucasian populations. The RA incidence rates appeared lower in France than in any other country in Europe, USA and Japan.

Abstract
Evidence is accumulating that low androgen concentrations are a cause of rheumatoid arthritis. This would explain a number of established features of the epidemiology of the disease. These include: (a) the variation of disease activity with pregnancy; (b) the variation of age at onset by sex; (c) the variation by sex with HLA-B15; (d) the association with bone mineral density; and (e) the differing time trends in incidence rates by sex. It is argued, moreover, that if one makes a plausible assumption--namely, that women who choose oral contraceptives have high androgen concentrations at the time they first make this choice--then an explanation becomes available for the confusion about the relation between rheumatoid arthritis and oral contraception. Grounds are adduced for that assumption. If this line of reasoning is substantially correct it also has implications for the relations between rheumatoid arthritis and smoking and consumption of alcohol.

Abstract
OBJECTIVE To determine whether women with rheumatoid arthritis (RA) had differences in obstetric and gynaecological histories when compared with sisters without RA (controls) METHODS Ninety eight RA discordant sister pairs, 36 of whom were identical for histocompatibility locus antigen (HLA-A, HLA-B, and HLA-Cw) types, were asked to recall their age of menarche, duration of use of contraceptive pill, pregnancy history, and age of menopause. RESULTS The 98 siblings with RA had an older mean age of menarche (13.90 (95% confidence interval (95% CI) 13.56 to 14.24) years) than their sisters (13.49 (95% CI 13.22 to 13.76) years; mean difference within pairs 0.41, 95% CI 0.09 to 0.73 years, paired t test t = 2.54, p = 0.013). When the pairs were divided into identical HLA and non-identical HLA groups, the first showed no significant difference (mean difference 0.17 (95% CI -0.40 to 0.73) years), whereas the second did (mean difference 0.55 (95% CI 0.16 to 0.94) years, t = 2.80, p = 0.007). A multiple regression analysis to predict differences in menarche in the non-identical HLA sibling pairs failed to show any demographic or reproductive confounding variables. In 19 RA concordant sibling pairs, the seven HLA identical pairs had similar ages of menarche, whereas the 12 non-identical HLA pairs had interpair differences that narrowly missed significance (p = 0.054). All other obstetric and gynaecological variables were not significantly different within the pairs. CONCLUSIONS The interpretations of these results are that either delayed menarche may predispose to or act as a marker of RA, or HLA linked genes are important in determining the age of menarche irrespective of disease state. This study fails to support a significant role for other obstetric and gynaecological variables in RA.

Abstract
Serum rheumatoid factors (RF) were measured yearly in 135 women with rheumatoid arthritis by the Waaler-Rose and latex fixation tests and IgM, IgA, and IgG RF were measured by enzyme linked immunosorbent assays (ELISAs). The patients were followed up from an early phase of the disease for a mean duration of six years. Patients with a persistently positive RF test, irrespective of the type of test used, had more radiological abnormalities, more disease activity, worse functional ability, more extra-articular manifestations, and needed more treatment with second line drugs than patients with persistently negative or variably positive and negative test results during the follow up. Increased RF levels, especially a high level of IgA RF within three years of the onset of symptoms, was prognostic for a more severe disease outcome six years after the onset of symptoms.

Abstract
The F1 hybrid mouse strain, from B10Q and DBA/1 parentals (the QD strain), is highly susceptible to induction of type II collagen-induced arthritis, an experimental model for rheumatoid arthritis. Males are more susceptible than females. Oophorectomy enhances susceptibility to arthritis and treatment with physiological doses of 17 beta-oestradiol (E2) suppresses disease. E2 treatment lowers the incidence of arthritis also in non-castrated and castrated males, showing that the anti-arthritic effect by oestrogen is not dependent on either sex hormone imprinting effects or interference with male sex hormones. Testosterone treatment of normal females, but not of castrated females, exaggerated development of the disease. In the testosterone-treated normal females, the oestrogen effect on vaginal smear was abolished and ovarian weight decreased, suggesting that the testosterone-mediated enhancing effect is caused by inhibition of ovarian oestrogen production. The crucial importance of oestrogens for the development of arthritis is focused on the effectiveness of treatment with gestation-related doses of E2 of normal, non-castrated females.

Abstract
Because oral contraceptives are used by tens of millions of healthy women, their safety for short-term and long-term use is an important issue that has been examined in a large number of epidemiologic studies. These studies have become more rigorous and have increased in size and analytic sophistication over the years. Although breast cancer remains the most important safety concern, the bulk of recent data suggests that oral contraceptives have no overall impact on a woman's risk of developing this disease. The results are less clear on the risk of cervical cancer and its precursors because of methodologic problems. However, the newer oral contraceptive formulations no longer appear to be associated with an increased risk of myocardial infarction or stroke.
