Chronic Primary or Secondary Noninflammatory Musculoskeletal Pain and Disrupted Sexual Function and Relationships: A Systematic Review.

OBJECTIVE: Evidence points to the impact of chronic musculoskeletal pain conditions on sexual function, yet there is little systematic appraisal and synthesis of evidence examining these associations across noninflammatory conditions. We aimed to systematically review evidence surrounding the association between chronic primary and chronic secondary musculoskeletal pain with intimate relationships and sexual function. METHODS: Four electronic databases were searched from January 1, 1990 to September 5, 2019 for cross-sectional or prospective epidemiologic and qualitative studies among cohorts with chronic primary or secondary noninflammatory musculoskeletal pain, defined by International Classification of Diseases, Eleventh Revision classification criteria. RESULTS: Fifty-one eligible studies were included (46 quantitative, 3 qualitative, 2 mixed-methods designs). Sample sizes ranged from 13 to 12,377 and mean age from 32.6 to 69.2 years. Cross-sectional controlled cohort studies consistently reported poorer sexual function outcomes among cohorts with pain relative to comparison groups. Of 15 studies reporting outcomes for the Female Sexual Function Index, 14 demonstrated mean scores of ≤26.55 for the pain group, indicating sexual dysfunction. In 4 studies reporting the International Index of Erectile Function, the pain cohorts demonstrated consistently lower mean subscale scores and the erectile function subscale scores were ≤25.0, indicating erectile dysfunction. Three key themes emerged from a meta-synthesis of qualitative studies: impaired sexual function; compromised intimate relationships; and impacts of pain on sexual identity, body image, and self-worth. CONCLUSION: Sexual dysfunction and negative impacts on intimate relationships are highly prevalent among people with chronic noninflammatory musculoskeletal pain. Consideration of these associations is relevant to the delivery of holistic, person-centered musculoskeletal pain care.

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

BACKGROUND: Autoimmune conditions (AICs) and/or their treatment may alter risk of human papilloma virus (HPV) infection and females with AICs are therefore at an increased risk of cervical dysplasia. However, inclusion of these at-risk populations in cervical cancer screening and HPV-vaccination guidelines, are mostly lacking. This study aimed to determine the prevalence of cervical dysplasia in a wide range of AICs and compare that to HIV and immunocompetent controls to support the optimisation of cervical cancer preventive health measures. METHODS: Data linkage was used to match cervical screening episodes to emergency department records of females with AICs or HIV to immunocompetent controls over a 14-year period. The primary outcome was histologically confirmed high-grade cervical disease. Results, measured as rates by cytology and histology classification per 1,000 females screened, were analysed per disease group, and intergroup comparisons were performed. RESULTS: Females with inflammatory bowel disease (2,683), psoriatic and enteropathic arthropathies (1,848), multiple sclerosis (MS) (1,426), rheumatoid arthritis (1,246), systemic lupus erythematosus and/or mixed connective tissue disease (SLE/MCTD) (702), HIV (44), and 985,383 immunocompetent controls were included. SLE/MCTD and HIV groups had greater rates of high-grade histological and cytological abnormalities compared to controls. Increased rates of low-grade cytological abnormalities were detected in all females with AICs, with the exception of the MS group. CONCLUSIONS: Females with SLE/MCTD or HIV have increased rates of high-grade cervical abnormalities. The increased low-grade dysplasia rate seen in most females with AICs is consistent with increased HPV infection. These findings support expansion of cervical cancer preventative programs to include these at-risk females.

Systematic Review of the Impact of Inflammatory Arthritis on Intimate Relationships and Sexual Function.

OBJECTIVE: To systematically review evidence of the impact of inflammatory arthritis on, or association of inflammatory arthritis with, intimate relationships and sexual function. METHODS: Ovid Medline, Ovid PsycINFO, Ovid Embase, and EBSCO CINAHL databases were searched. Two independent reviewers selected articles, extracted data, and conducted manual searches of reference lists from included studies and previous reviews. The quality of evidence was assessed using standard risk-of-bias tools. RESULTS: Fifty-five eligible studies were reviewed. Of these, 49 (89%) were quantitative, 5 (9.1%) were qualitative, and 1 (1.8%) used a mixed-method design. Few quantitative studies were rated as low risk of bias (n = 7 [14%]), many were rated as moderate (n = 37 [74%]) or high risk (n = 6 [12%]). Quantitative study sample sizes ranged from 10 to 1,272 participants, with a reported age range 32-63 years. Qualitative study sample sizes ranged from 8 to 57 participants, with a reported age range 20-69 years. In studies reporting the Female Sexual Function Index, all inflammatory arthritis groups demonstrated mean scores ≤26.55 (range of mean ± SD scores: 14.2 ± 7.8 to 25.7 ± 4.7), indicating sexual dysfunction. In studies reporting the International Index of Erectile Function, all inflammatory arthritis groups reported mean scores ≤25 (range of mean ± SD scores: 16.0 ± 5.3 to 23.8 ± 7.0), indicating erectile dysfunction. Key qualitative themes were impaired sexual function and compromised intimate relationships; prominent subthemes included inflammatory arthritis-related pain and fatigue, erectile dysfunction, diminished sexual desire, and sexual function fluctuations according to disease activity. CONCLUSION: Sexual dysfunction appears highly prevalent among men and women with inflammatory arthritis, and increased clinician awareness of this impairment may guide provision of tailored education and support.

Establishing cross-discipline consensus on contraception, pregnancy and breast feeding-related educational messages and clinical practices to support women with rheumatoid arthritis: an Australian Delphi study.

OBJECTIVE: Recognising the need for a best-practice and consistent approach in providing care to women with rheumatoid arthritis (RA) in relation to (1) general health, (2) contraception, (3) conception and pregnancy, (4) breast feeding and (5) early parenting, we sought to achieve cross-discipline, clinical consensus on key messages and clinical practice behaviours in these 5 areas. DESIGN: 3-round eDelphi study. In round 1, panellists provided free-text responses to open-ended questions about care for women with RA across the 5 areas. Subsequently, panellists refined and scored the synthesised responses, presented as metathemes, themes and detailed elements. Where ≥5% of panellists did not support a theme in a given round, it was removed. SETTING: Panel of practicing Australian rheumatologists (n=22), obstetricians/obstetric medicine physicians (n=9) and pharmacists (n=5). RESULTS: 34 (94.4%) panellists participated in all 3 rounds. The panel supported 18 themes across the 5 areas (support/strongly support: 88.2-100%) underpinned by 5 metathemes. Metathemes focused on coordination in information delivery, the mode and timing of information delivery, evidence underpinning information, engagement of the right health professionals at the right time and a non-judgemental approach to infant feeding. Themes included practices for primary prevention of chronic disease and their sequelae, the importance of contraception and planning pregnancy and breast feeding, close monitoring of medications, supporting mental well-being, managing disease activity and providing practical support for early parenting. CONCLUSIONS: A cross-disciplinary clinical panel highly supported key information and clinical practices in the care for women with RA across the continuum of contraception to early parenting within a whole-person, chronic disease management approach.

Safety of anti-rheumatic drugs for rheumatoid arthritis in pregnancy and lactation.

Women with rheumatoid arthritis (RA) are often of childbearing age and therefore questions regarding reproductive health and the use of medications, including disease-modifying anti-rheumatic drugs (DMARDs) may arise during the clinical consultation. Each patient requires individual assessment in order to effectively manage the disease while minimizing any treatment-associated risks to the fetus. Although good-quality controlled trials are lacking, there is an increasing volume of evidence surrounding the use of immunosuppressive therapies in pregnancy and lactation. This review summarizes the currently available information which can be of benefit to clinicians guiding patients and their families through the risks and benefits of continuing RA therapy during pregnancy and lactation. Further studies and ongoing surveillance of drug safety in pregnancy are required to resolve the uncertainties that remain regarding synthetic and biologic DMARDs.

Myocardial infarction and mortality following joint surgery in patients with rheumatoid arthritis: a retrospective cohort study.

BACKGROUND: Rheumatoid arthritis (RA) is associated with an increased risk of myocardial infarction (MI) and post-MI fatality compared with the general population. In a previous study examining post-MI treatment in RA compared with controls we noted that a higher proportion of the RA patients had experienced MI following a surgical procedure. The aim of this study was to compare the risk of MI and mortality at 6 weeks and 12 months following joint surgery in patients with RA compared with the general population. METHODS: Individuals who had undergone joint surgery in Victoria, Australia between 1 July 2000 and 30 June 2007 were identified from routinely collected hospital administrative data. Logistic regression analysis was performed to examine odds of 6 week and 12 month MI and mortality in RA versus non-RA patients with adjustment for age, sex, comorbidities, socioeconomic status, patient type and admission type. Subgroup analysis of total hip and knee arthroplasty episodes was undertaken. RESULTS: A total of 308,589 episodes of joint surgery occurred among 240,571 individuals, with 3654 (1.2 %) occurring among patients with RA. At 6 weeks post joint surgery the adjusted odds ratio (OR) for MI was 1.50 (95 % CI 0.96-2.33), all-cause death was 1.85 (95 % CI 1.09-3.13) and cardiovascular death was 1.90 (95 % CI 1.07-3.37). At 12 months post joint surgery the adjusted OR of MI was 1.70 (95 % CI 1.27-2.28), all-cause death was 2.18 (95 % CI 1.66-2.86) and cardiovascular death was 2.30 (95 % CI 1.65-3.22). On analysis of joint surgeries other than hip or knee arthroplasty, people with RA were at greater risk of MI within 6 weeks (adjusted OR 2.32; 95 % CI 1.24-4.34) and 12 months (adjusted OR 2.20; 95 % CI 1.47-3.30) compared to those without RA, but no difference in odds of short term mortality were found. CONCLUSIONS: Following an episode of joint surgery RA patients have a significantly increased risk of death at 6 weeks, and MI and death at 12 months, compared to the general population. The reasons for this remain to be elucidated but in the meantime RA patients should be considered at higher risk in the perioperative period.

Management of pregnancy in women with rheumatoid arthritis.

Rheumatoid arthritis (RA) disease activity may improve during pregnancy but postpartum flares are common. Patients taking disease-modifying antirheumatic drugs should be counselled about effective contraception. Knowledge about drug safety in pregnancy is limited but the Therapeutic Goods Administration categories and online resources are a guide to the data currently available. Begin prepregnancy counselling as early as possible to allow for cessation of teratogenic medications and optimisation of RA disease control. For unplanned pregnancies, cease teratogenic medications immediately and refer to a genetic counsellor and maternal-fetal medicine specialist for risk assessment and advice.

Suppression of inflammatory disease activity in rheumatoid arthritis is associated with improvements in retinal microvascular health.

OBJECTIVE: To investigate the effect of suppressing inflammation on retinal microvascular health in patients with RA. METHODS: Two groups of patients with RA were recruited and studied concurrently. Group A included patients with moderate to high disease activity [28-joint DAS with CRP (DAS28-CRP) >3.2] requiring treatment escalation, while group B had stable low disease activity (DAS28-CRP ≤3.2) not requiring treatment escalation. Retinal photography was performed at baseline and weeks 6 and 24 in group A and at baseline and week 12 in group B. RESULTS: Group A included 26 patients with a mean age of 50.7 years (s.d. 3.5) and a mean disease duration of 7.1 years (s.d. 8.0). Disease activity significantly improved during follow-up and was accompanied by a significant reduction in retinal venular calibre at week 6 [mean difference (MD) -7.9 µm (95% CI -13.3, -2.5)] and at week 24 [MD -6.8 µm (95% CI -12.2, -1.4)]. No significant change in retinal arteriolar calibre was identified at week 6 [MD -0.6 µm (95% CI -4.5, 3.28)] or week 24 [MD 0.7 µm (95% CI -3.1, 4.5)]. Group B included 27 patients with a mean age of 54.6 years (s.d. 1.8) and a mean disease duration of 14.5 years (s.d. 10.9). Disease activity and therapy remained unchanged during follow-up and no significant changes in retinal venular [MD 1.81 µm (95% CI -2.32, 5.95)] or arteriolar [MD 0.54 µm (95% CI -2.77, 3.86)] calibre were observed. CONCLUSION: We demonstrated that suppression of inflammation in RA is associated with a reduction of retinal venular calibre, suggesting that therapies targeting inflammation could improve vascular health in RA.

A systematic review of interventions to improve knowledge and self-management skills concerning contraception, pregnancy and breastfeeding in people with rheumatoid arthritis.

This systematic review aimed to determine the effectiveness of interventions for improving knowledge and/or self-management skills concerning contraception, pregnancy and breastfeeding in people with rheumatoid arthritis (RA). We searched four databases (MEDLINE, CINAHL, Cochrane Trials, PsycINFO) using a comprehensive search strategy. Studies were eligible if they were prospective, published in English from 2004 to 2015, included participants with RA and tested an intervention designed to improve knowledge and/or self-management skills relating to family planning, pregnancy or breastfeeding. As no studies met the latter criterion, the search strategy was expanded to include all prospective studies evaluating RA educational and/or self-management interventions. Data on study characteristics, participant characteristics and programme content were extracted to summarise the evidence base for interventions to support people with RA during their reproductive years. Expanded literature searches identified 2290 papers, of which 68 were eligible. Of these, nine papers (13%) specifically excluded pregnant women/breastfeeding mothers or recruited only older people. Only one study (1%) explicitly evaluated pregnancy-focused education via a motherhood decision aid, while eight studies (12%) incorporated relevant (albeit minor) components within broader RA educational or self-management interventions. Of these, three studies provided methotrexate education in relation to conception/pregnancy/breastfeeding; three incorporated discussions on RA and relationships, impact of RA on the family or sexual advice; one provided information regarding contraception and fertility; and one issued a warning regarding use of biologic therapy in pregnancy/breastfeeding. In conclusion, information regarding family planning, pregnancy or breastfeeding represents a negligible part of published RA educational interventions, with scope to develop targeted resources.

Malignancy risk in Australian rheumatoid arthritis patients treated with anti-tumour necrosis factor therapy: analysis of the Australian Rheumatology Association Database (ARAD) prospective cohort study.

BACKGROUND: Malignancy risk with tumour necrosis factor inhibitor (TNFi) therapy remains unclear. Our primary aim was to assess malignancy risk with TNFi therapy in a cohort of Australian patients with rheumatoid arthritis (RA). We also assessed risk in a biologic-naïve group. METHODS: Demographic data of all RA patients enrolled in the Australian Rheumatology Association Database before 25 October 2010 were matched to national cancer records in July 2010 (linkage complete to 2007). Verified self-reported malignancies occurring between 1 January 2008 and 25 October 2010 were also included in the analysis. Standardised incidence ratios (SIRs) were used to compare malignancy incidence in biologic-naïve and TNFi-exposed ARAD participants to the general population using site-, age- and sex-specific rates by calendar year. Rate ratios (RRs) were used to compare malignancy incidence in TNFi-exposed participants to biologic-naïve RA patients, and a composite RA cohort that included pre-TNFi person years, both adjusted for age, gender, smoking, methotrexate use and prior malignancy. RESULTS: Forty-four malignancies were reported after 5752 person-years in the TNFi-exposed group (N = 2145) and 32 malignancies were reported after 1682 person-years in the biologic-naïve group (N = 803). No overall increased risk of malignancy in TNFi-treated RA patients was found when compared with the general population or with biologic-naïve RA patients. Compared to the biologic naïve group, without the inclusion of pre-TNFi years in the comparator group, the relative risk of female breast cancer was reduced in TNFi-treated patients (RR 0.17 (95 % CI 0.03 to 0.95)). It was no longer significant when adding pre-TNFi years in the comparator group. The risk of melanoma was increased for both biologic naïve and TNFi-treated patients when compared with the general population (SIR 2.72 (95 % CI 1.13 to 6.53) and SIR 2.03 (95 % CI 1.09 to 3.78) respectively). The relative risk of melanoma was not increased in the TNFi-exposed group compared with biologic naïve patients (RR 0.54, 95 % CI 0.12, 2.40). Inclusion of pre-TNFi person years in the comparator group did not change these results. CONCLUSIONS: Malignancy incidence was low in this RA cohort and biologic exposure did not increase the risk of malignancy. Melanoma risk was increased in both TNFi-treated and biologic-naïve RA patients compared with the general population suggesting that RA status, and possibly methotrexate exposure, may be responsible.

Understanding the information needs of women with rheumatoid arthritis concerning pregnancy, post-natal care and early parenting: A mixed-methods study.

BACKGROUND: Although women with rheumatoid arthritis (RA) face a number of challenges in negotiating the journey to parenthood, no studies have explored the information needs of women with RA in relation to their childbearing years. This study aimed to determine the need for (and preferred mode/s of delivery of) information regarding pregnancy, post-natal care and early parenting among women with RA. METHODS: Interviews and focus groups were conducted with 27 women with RA who were pregnant in the last 5 years, currently pregnant or planning pregnancy. Verbatim transcripts were analysed using both inductive and deductive approaches. Two validated instruments were used to quantify information needs and preferences: the Educational Needs Assessment Tool (ENAT, range 0-156, higher scores indicate higher educational needs) and the Autonomy Preference Index (API, range 0-100, higher scores indicate stronger preferences). RESULTS: Lack of information about medication safety, access to physical/emotional support services and practical strategies for coping with daily challenges related to parenting were the most prominent of the six key themes identified. Rheumatologists were the primary source for information regarding treatment decisions while arthritis consumer organisations were perceived as critical 'resource hubs'. There was strong preference for information delivered electronically, especially among rural participants. Quantitative outcomes supported the qualitative findings; on average, participants reported high educational needs (mean ENAT score 97.2, SD 30.8) and API scores indicated that desire for information (mean 89.8, SD 5.6) was greater than the need for involvement in treatment decision-making (mean 68.4, SD 8.2). CONCLUSIONS: Many women with RA struggle to find adequate information on pregnancy planning, pregnancy and early parenting in relation to their chronic condition, and there is a clear need to develop accessible information that is consumer-focused and evidence-based. Although most participants trusted their rheumatologist as their primary information source, there was consistent demand for more information, particularly regarding the safety of RA medications during pregnancy and breastfeeding, and the importance of learning from other women's personal experiences was strongly emphasised.

Increased 30-day and 1-year mortality rates and lower coronary revascularisation rates following acute myocardial infarction in patients with autoimmune rheumatic disease.

INTRODUCTION: It is now well-recognised that patients with autoimmune rheumatic disease (AIRD) have a predisposition to cardiovascular disease that results in increased morbidity and mortality. Following myocardial infarction (MI), patients with rheumatoid arthritis have been shown to have an increased case fatality rate; however, this has not been demonstrated in other forms of AIRD. The aim of this study was to compare case fatality rates following a first MI in patients with AIRD versus the general population. The secondary aim was to compare revascularisation treatment following MI in patients with AIRD versus the general population. METHODS: A retrospective cohort study using two population-based linked databases was undertaken. Cases of first MI from July 2001 to June 2007 were identified based on International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification, codes. Thirty-day and one-year mortality rates were calculated (all-cause and cardiovascular causes of death). Logistic regression models were fitted to calculate the odds of mortality by AIRD status with adjustment for relevant characteristics. RESULTS: There were 79,390 individuals with a first MI, of whom 1,409 (1.8%) had AIRD. After adjusting for relevant covariates, the odds ratio (OR) for 30-day cardiovascular mortality in patients with AIRD was 1.44 (95% confidence interval (CI): 1.25 to 1.66), and the OR for 12-month cardiovascular mortality was 1.71 (95% CI: 1.51 to 1.94). The 90-day adjusted odds of percutaneous transluminal coronary angioplasty and coronary artery bypass graft were significantly lower in the AIRD group compared with controls (OR: 0.81, 95% CI: 0.70 to 0.94, and OR: 0.52, 95% CI: 0.39 to 0.69, respectively). CONCLUSIONS: We identified a higher risk-adjusted mortality rate for the majority of patients with AIRD at 30 days and 12 months after first MI. We also identified lower post-MI revascularisation rates in the AIRD group, suggesting there may be current gaps in cardiovascular treatment for patients with AIRD.

Statin initiation and treatment non-adherence following a first acute myocardial infarction in patients with inflammatory rheumatic disease versus the general population.

INTRODUCTION: To compare statin initiation and treatment non-adherence following a first acute myocardial infarction (MI) in patients with inflammatory rheumatic disease (IRD) and the general population. METHODS: We conducted a retrospective cohort study using a population-based linked database. Cases of first MI from July 2001 to June 2009 were identified based on International Classification of Diseases (ICD-10-AM) codes. Statin initiation and adherence was identified based on pharmaceutical claims records. Logistic regression was used to assess the odds of statin initiation by IRD status. Non-adherence was assessed as the time to first treatment gap using a Cox proportional hazards model. RESULTS: There were 18,518 individuals with an index MI over the time period surviving longer than 30 days, of whom 415 (2.2%) were IRD patients. The adjusted odds of receiving a statin by IRD status was significantly lower (OR =0.69, 95% CI: 0.55 to 0.86) compared to the general population. No association between IRD status and statin non-adherence was identified (hazard ratio (HR) =1.12, 95% CI: 0.82 to 1.52). CONCLUSIONS: Statin initiation was significantly lower for people with IRD conditions compared to the general population. Once initiated on statins, the proportion of IRD patients who adhered to treatment was similar to the general population. Given the burden of cardiovascular disease and excess mortality in IRD patients, encouraging the use of evidence-based therapies is critical for ensuring the best outcomes in this high risk group.

Glucocorticoid-induced bone loss is associated with abnormal intravertebral areal bone mineral density distribution.

Individuals with glucocorticoid-induced osteoporosis experience vertebral fractures at an increased rate and at higher vertebral areal bone mineral density (aBMD) than individuals with primary osteoporosis. Standard posteroanterior- (PA-) projection dual energy X-ray absorptiometry (DXA) lacks the diagnostic sensitivity required for reliable estimation of vertebral fracture risk in individuals. Assessment of subregional vertebral aBMD using lateral-projection DXA may improve the predictive value of DXA parameters for fracture. One hundred and four individuals were recruited and grouped for this study: primary osteoporosis with no history of vertebral fracture (n = 43), glucocorticoid-induced bone loss (n = 13), and healthy controls (n = 48). Standard PA-projection and supine-lateral scans were performed, and lateral scans were analysed according to an established protocol to measure aBMD within 6 subregions. Main effects for subregion and group were assessed and observed, by ANCOVA. Ratios were calculated between subregions and compared between groups, to overcome the potentially confounding influence of variability in subregional geometry. Significantly lower values were observed in the glucocorticoid group for the ratios of (i) anterior subregion: whole vertebral body and (ii) posterior: whole vertebral body when compared to the primary osteoporosis and control groups (P < 0.05). Lower anterior subregional aBMD in individuals on glucocorticoid therapy may help to explain the increased vertebral fracture risk in this patient group.

Prevalence of coronary heart disease and cardiovascular risk factors in a national cross-sectional cohort study of systemic sclerosis.

OBJECTIVES: To determine the prevalence of coronary heart disease (CHD) and cardiovascular risk factors in a well-characterised cohort of systemic sclerosis (SSc) patients, and to compare this with the general population. METHODS: A cross-sectional study of the prevalence of CHD and cardiovascular risk factors in participants in the Australian Scleroderma Cohort Study was performed. Controls were drawn from the 2007-8 National Health Survey (NHS) and the Australian Diabetes, Obesity and Lifestyle Study (AusDiab). OR and 95% CI were calculated to determine the prevalence of CHD and cardiovascular risk factors in SSc patients compared with controls. RESULTS: Data were available for 850 SSc patients (86% female), 15 787 NHS participants (53% female) and 8802 AusDiab participants (56% female). Adjusted for age and gender, the OR of CHD in SSc patients was 1.9 (95% CI 1.4 to 2.4) compared with controls from AusDiab and 2.0 (95% CI 1.5 to 2.5) compared with controls from the NHS. The OR of CHD increased to 3.2 (95% CI 2.3 to 4.5) for SSc patients compared with controls from AusDiab after further adjustment for cardiovascular risk factors. Hypercholesterolaemia, diabetes mellitus and obesity were significantly less prevalent in the SSc cohort than in AusDiab. Within the SSc cohort, the presence of pulmonary arterial hypertension was associated with CHD. CONCLUSIONS: This is the first report of an increased prevalence of CHD in SSc patients. Further studies are required to determine the relative contribution of scleroderma-specific factors such as microvascular disease to the development of CHD.

Cardiovascular disease in systemic sclerosis--an emerging association?

Microvascular disease is a prominent feature of systemic sclerosis (SSc) and leads to Raynaud's phenomenon, pulmonary arterial hypertension, and scleroderma renal crisis. The presence of macrovascular disease is less well established, and, in particular, it is not known whether the prevalence of coronary heart disease in SSc is increased. Furthermore, in terms of cardiac involvement in SSc, there remains conjecture about the relative contributions of atherosclerotic macrovascular disease and myocardial microvascular disease. In this review, we summarize the literature describing cardiovascular disease in SSc, discuss the pathophysiological mechanisms common to SSc and atherosclerosis, and review the surrogate markers of cardiovascular disease which have been examined in SSc. Proposed mediators of the vasculopathy of SSc which have also been implicated in atherosclerosis include endothelial dysfunction, a reduced number of circulating endothelial progenitor cells, and an increased number of microparticles. Excess cardiovascular risk in SSc is suggested by increased arterial stiffness and carotid intima thickening and reduced flow-mediated dilatation. Cohort studies of adequate size are required to resolve whether this translates into an increased incidence of cardiovascular events in patients with SSc.

Retinal vascular calibre is altered in patients with rheumatoid arthritis: a biomarker of disease activity and cardiovascular risk?

OBJECTIVES: Alterations in retinal vascular calibre, particularly wider venular calibre, have been independently associated with elevated markers of inflammation and cardiovascular risk in the general population. We hypothesized that retinal vascular calibre would be altered in patients with RA, who are known to have both elevated cardiovascular risk and chronic, systemic inflammation. METHODS: Retinal vascular calibre was measured from digital retinal photographs using computerized methods in 51 RA patients and 51 age- and gender-matched controls. Retinal vascular calibre was compared between RA and control patients with adjustment for relevant variables including cardiovascular risk factors and companion vessel calibre. The relationship between retinal venular calibre and inflammation was assessed by comparing controls and RA patients with high and lower disease activity. RESULTS: Retinal venular calibre [mean (s.d.)] was significantly wider in RA patients than in controls [235.9 (24.6) vs. 211.6 (21.0) µm, P < 0.001]. After adjustment for all relevant variables, mean venular calibre remained 20.3 µm (95% CI 10.4, 30.3) wider in RA patients compared with controls. Retinal venular calibre [mean (s.d.)] also increased with increasing levels of systemic inflammation: 211.6 (21.0) µm in controls, 232.3 (22.4) µm in RA patients with moderate or lower disease activity and 255.5 (28.3) µm in RA patients with high disease activity (P for trend < 0.0001). CONCLUSIONS: This study demonstrates that RA patients have dilated retinal venular calibre, reflecting systemic inflammation and possibly increased cardiovascular risk. Longitudinal studies correlating retinal vascular calibre with subsequent cardiovascular events will clarify the clinical utility of this test in patients with RA.

Rheumatoid arthritis patients receive less frequent acute reperfusion and secondary prevention therapy after myocardial infarction compared with the general population.

INTRODUCTION: The 30-day case-fatality rate after acute myocardial infarction (MI) for rheumatoid arthritis (RA) patients is twice that of the general population. This study compared the frequency and timeliness of early reperfusion therapy and treatment with secondary prevention medications after acute MI in RA patients and controls. METHODS: We performed a structured medical chart review of RA patients and matched controls who had been admitted with acute MI to one of three hospitals in Victoria, Australia, between 1995 and 2005. The administration and timing of acute reperfusion therapy and in-hospital treatment with secondary prevention medications were compared between the two groups. Acute reperfusion was defined as thrombolysis or percutaneous coronary intervention (PCI) within 12 hours of the first symptom of MI. RESULTS: The medical charts of 90 RA patients and 90 matched controls were reviewed. The RA patients were significantly less likely to receive acute reperfusion compared with the controls (16% versus 37%: odds ratio (OR), 0.27; 95% confidence interval (CI), 0.10 to 0.64)), and this difference persisted after adjusting for type of MI, clinical setting of MI, and prior MI (OR, 0.2; 95% CI, 0.05 to 0.6). The RA patients also received less-frequent in-hospital treatment with beta blockers (71% versus 83%; OR, 0.42; 95% CI, 0.18 to 0.96) and lipid-lowering agents (40% versus 70%; OR, 0.21; 95% CI, 0.09 to 0.46). CONCLUSIONS: RA patients who experience acute MI receive acute reperfusion and secondary prevention medications less frequently than do controls. This may contribute to higher case-fatality rates after MI in RA patients.
