- Background: The risk of cardiovascular disease (CVD), microangiopathy and prevalence of atherosclerotic plaques are increased in Systemic Lupus Erythematosus (SLE). As systemic endothelial dysfunction is one of the earliest signs of these vascular outcomes in the general population we assessed skin microvascular endothelial function in SLE patients. Methods: Endothelial function in skin was tested with local application of acetylcholine (inducing endothelium-dependent vasodilatation) and any concomitant increase in skin perfusion was measured with Laser Doppler Fluxmetry (LDF) in 84 SLE-patients (83% women, mean age 47 years) and 81 age and sex matched controls. Common carotid intima-media thickness (cIMT) and plaque occurrence were also determined using B-mode ultrasound. Results: There were no significant differences in skin microvascular endothelial function between SLE-patients and controls. In the SLE group, endothelial function did not vary in relation to skin manifestations, Raynaud's phenomenon, nephritis or plaque occurrence. In SLE patients with CVD, however, endothelial function was impaired. Conclusion: Skin microvascular endothelial function is associated with CVD but not with early signs of atherosclerosis in SLE-patients. The endothelial function is not different in SLE-patients as compared to controls.

- As carotid endarterectomy is a prophylactic procedure, it would seem particularly important to analyze complications with an aim to avoiding them. All carotid endarterectomies in Sweden are registered, and all serious complications (death and permanent neurological deficit) are analyzed in detail, classified and discussed within the profession. During the period 1994-1996 the frequency was 4.3 percent (technical causes in 17 percent, contraindications in 8 percent and dubious indications in 21 percent, but correct indication and surgery in 54 percent). Thus, even when conditions are optimal there is a certain price to pay for the prevention of ischemic stroke.

- Objective: As atherosclerosis is increased in systemic lupus erythematosus (SLE) we compared dietary habits in patients with SLE with controls, and in the patients studied associations of diet components, especially fatty acids (FAs), with disease activity, serum lipids and carotid plaque presence. Methods: In all 114 patients with SLE and 122 age- and sex-matched population-based controls answered a food frequency questionnaire (FFQ). Subcutaneous abdominal fat cell aspiration was analysed as to FA content and plaque occurrence was determined by B-mode ultrasound. Results: The total diet energy intake did not differ between patients and controls. However, the patients with SLE reported a higher intake of carbohydrate, lower fibre intake and lower intake of omega-3 and omega-6, than controls ( p < 0.05). In the patients, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in adipose tissue (AT) correlated negatively with disease activity (SLEDAI), r = −0.36, p = <0.001 and r = −0.33, p = < 0.001, respectively. AT omega-3 was further positively associated with serum apoA1, r = 0.29, p = 0.004, whereas AT omega-6 showed a negative association, r = −0.21, p = 0.040. These FAs also had opposite associations with plaque presence, EPA and were DHA negative, r = −0.32, p = 0.002 and r = −0.33, p = 0.001, respectively, and omega-6 positive, r = 0.22, p = 0.027. The carbohydrate intake was positively correlated to AT omega-6, r = 0.38, p < 0.001, and negatively with serum apoA1, r = −0.27, p = 0.005. Conclusion: The macronutrient dietary pattern is different in SLE as compared with controls. The low intake of omega-3 and high intake of carbohydrate among patients with SLE appear to be associated with worse disease activity, adverse serum lipids and plaque presence.

- The aim of this study was to investigate the role of dietary micronutrient intake in systemic lupus erythematosus (SLE). Methods This study included 111 SLE patients and 118 age and gender-matched controls. Data on diet (food frequency questionnaires) were linked with data on Systemic Lupus Activity Measure, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and carotid atherosclerotic/echolucent plaque (B-mode ultrasound). Dietary micronutrient intake were compared between SLE patients and controls and in relation to lupus activity and atherosclerosis in SLE. Associations between micronutrient intake and plaque were analyzed through logistic regression, adjusted for potential confounders. Results Micronutrient intake did not differ between patients and controls, and between lower and higher lupus activity, apart from the fact that phosphorus was associated with SLEDAI > 6. In SLE patients, some micronutrients were associated with atherosclerotic plaque, left side. Lower intake of riboflavin and phosphorus was associated with atherosclerotic plaque, left side (odds ratio (OR) 3.06, 95% confidence interval (CI) 1.12–8.40 and OR 4.36, 95% CI 1.53–12.39, respectively). Higher intake of selenium and thiamin was inversely associated with atherosclerotic plaque, left side (OR 0.28, 95% CI 0.09–0.89 and OR 0.26, 95% CI 0.08–0.80, respectively). In addition, higher intake of thiamin was inversely associated with echolucent plaque, left side (OR 0.22, 95% CI 0.06–0.84). Lower intake of folate was inversely associated with bilateral echolucent plaque (OR 0.36, 95% CI 0.13–0.99). Conclusions SLE patients did not have different dietary micronutrient intake compared to controls. Phosphorus was associated with lupus activity. Riboflavin, phosphorus, selenium and thiamin were inversely associated with atherosclerotic plaque, left side in SLE patients, but not in controls. Dietary micronutrients may play a role in atherosclerosis in SLE.

- We have reported that the prevalence of atherosclerotic plaques and their echolucency was increased in systemic lupus erythematosus (SLE). We here study antibodies against oxidized cardiolipin (anti-OxCL) and phosphatidylserine (anti-OxPS) in SLE and in relation to atherosclerosis measures.Methods.Patients with SLE (n = 114) were compared with age- and sex-matched population-based controls (n = 122). Common carotid intima-media thickness and plaque occurrence were determined by B-mode ultrasonography. Plaques were graded according to echogenicity as 1–4, with 1 being echolucent. Antibodies were determined by ELISA.Results.In the SLE group, the prevalence of low IgM anti-OxPS and low total IgM levels (below 33rd percentile) was increased compared to controls (p = 0.045 and p = 0.0079, respectively). Among SLE patients with atherosclerotic plaques, the prevalence of low IgM anti-OxPS (p = 0.0019) and anti-OxCL (p = 0.031) was increased. Only IgM anti-OxPS remained significant (p = 0.019) after adjusting for other significant factors. Echolucent plaques (total, or left side) were more prevalent among SLE patients with low IgM anti-OxCL and anti-OxPS when controlled for other significant factors (p < 0.05). Low total IgM was independently associated with echolucent plaque on left side (p < 0.05), but not other atherosclerosis measures. IgM anticardiolipin antibodies (aCL) and antiphosphatidylserine antibodies (anti-PS) were higher among SLE patients with cardiopulmonary disease, including arterial, valvular, and venous disease (p < 0.05). There were no associations between antibodies and other disease manifestations or activity. Both anti-OxCL and anti-OxPS, in contrast to aCL, and anti-PS, were cofactor−β2-glycoprotein I (β2-GPI)-independent.Conclusion.The prevalence of low levels of IgM anti-OxCL and anti-OxPS (both cofactor-β2-GPI-independent) is associated with the presence of plaques and echolucent plaques in SLE.

- Carotid surgery prevents recurrent stroke in patients with symptomatic tight stenosis of the carotid artery. The Swedish Carotid Surgery Monitoring Registry seeks to promote selection of patients with significant spontaneous risk for recurrent stroke, with an eye toward expediting evaluation and minimizing surgical complications. To this end, professionals at participating hospitals are informed about their own patient selection and surgery risk in comparison with those in the country as a whole and with set targets. We report the results from the first two years, during which it is estimated that more than half of all patients eligible for carotid surgery in Sweden were included in the registry. Although almost all patients had recent onset of relevant neurological symptoms, less than 60% had a documented tight (80-99% occlusion) stenosis. While the final decision to operate a patient was made within 4 weeks of onset of symptoms for only 18% of the patients the first year, this proportion increased to 33% in the following year. The total incidence of surgery related stroke, myocardial infarct and death was 7.7%, while the incidence of severe stroke, myocardial infarct and death was 3.0%.
