Purpose: To evaluate sexual function of antiphospholipid syndrome (APS) patients using the Brazilian version of the validated International Index of Erectile Function (IIEF).Materials and methods: Eleven APS male patients (Sapporo criteria) were age and race-matched with 22 healthy controls. Demographic and clinical data, drug use and antiphospholipid antibodies were evaluated. The IIEF was also self-applied.Results: Mean age (p = 0.114), frequency of Caucasian race (p = 1.00) and married status (p = 0.438) were similar in APS and controls. Mean disease duration was 8.8 ± 4.6 years. Erectile dysfunction (ED) was frequently observed in APS versus controls (45.5 vs. 4.5%, p = 0.0096), especially moderate/severe ED (p = 0.0081). The total IIEF score (49.6 vs. 67.1, p = 0.019), erectile function (19.6 vs. 28.1, p = 0.005) and intercourse satisfaction (7.8 vs. 11.9, p = 0.009) were lower in patients than in controls. No differences were seen in orgasmic function (p = 0.114), sexual desire (p = 0.123) or overall satisfaction (p = 0.097) between the groups. The comparison between APS patients with ED (n = 5) and without ED (n = 6) revealed more arterial events in APS with ED (100 vs. 16.7%, p = 0.0152), and also longer disease duration (12 [7–16] vs. 5.5 [2–13] years, p = 0.031). A trend towards lower venous events (20 vs. 83.3%, p = 0.0801) and higher renal thrombotic microangiopathy (60% vs. 0, p = 0.0606) was observed in APS patients with ED. Demographics, clinical manifestations, smoking and antiphospholipid antibodies positivity were similar in both groups.Conclusion: To our knowledge, this was the first study that demonstrated moderate/severe ED in almost 50% of cases of a rare autoimmune disease. This alteration was linked to arterial events and longer disease duration. [ABSTRACT FROM AUTHOR]

Fibromyalgia (FM) is a syndrome that can be associated with several rheumatic diseases. However, no study has evaluated its frequency in patients with primary antiphospholipid syndrome (PAPS). The objective of this study was to analyze the frequency of FM in PAPS patients compared with healthy controls, to determine the possible associations between FM and PAPS features, and also to evaluate quality of life and depression in these patients. This case–control study included 30 PAPS patients (by the Sapporo criteria) and 40 healthy subjects. Demographic and clinical data, drug use, and antiphospholipid antibodies were analyzed. FM was diagnosed based on international criteria (ACR). Questionnaires on quality of life, including the Short Form 36 Health Survey (SF-36), Beck Depression Inventory (BDI), Fibromyalgia Impact Questionnaire (FIQ), and Visual Analog Scale (VAS), were also applied. PAPS patients and controls were similar in mean age as well as in distributions of gender and Caucasian race. Mean disease duration was 5.4 ± 4.2 years. A diagnosis of fibromyalgia was made in five (16.7%) PAPS patients and no controls (p = 0.012). PAPS patients had more diffuse pain (53% vs. 0%, respectively, p < 0.0001), ≥11 tender points (23% vs. 5%, respectively, p = 0.032), and a greater total number (175 vs. 57, respectively, p < 0.0001) as well as median number of tender points per patient than controls (5 [0–18] vs. 0 [0–11], respectively, p < 0.0001). PAPS patients had lower values in all dimensions of the SF-36, as well as higher FIQ scores, higher BDI scores, more depression diagnoses according to BDI results, and increased VAS in comparison with controls. Analysis of PAPS patients with FM compared with those subjects without FM revealed no significant differences regarding demographic features or thrombotic or clinical events; however, PAPS patients who also had FM had lower values in SF-36 dimensions as well as higher FIQ (82.6 ± 9.6 vs. 33.6 ± 29.8, respectively, p < 0.0001) and VAS scores (6.6 ± 2.97 vs. 3.25 ± 3.11, respectively, p = 0.03). BDI scores, in contrast, were similar in both groups. In conclusion, one-fifth of PAPS patients had fibromyalgia and a low quality of life when compared with healthy subjects.

Neuropsychiatric conditions are common in patients with primary antiphospholipid syndrome (APS) with or without vascular thrombosis of the central nervous system. There are frequent descriptions of memory alterations, cognition and mood disorders, such as depression, anxiety, and even conditions of mania and psychosis preceding the diagnosis of primary APS. However, this study is the first to present primary or secondary APS associated with habit or impulse control disorders. The authors describe the case of a 53-year-old male patient who had been a pathological gambler since adulthood and who has had APS for more than 20 years. We describe the case and review its characteristics, criteria for diagnosis and treatment offered for patients with this specific subtype of impulse disorder. [ABSTRACT FROM PUBLISHER]

Objectives: To compare prognosis parameters and arterial site involvement in Takayasu arteritis (TA) patients with disease onset at age ≤ 18 and ≥ 21 years. Methods: Sixty-two TA patients [American College of Rheumatology (ACR) and European League Against Rheumatism/Paediatric Rheumatology European Society (EULAR/PreS) criteria] were enrolled consecutively and divided into two groups according to disease onset, and matched for disease duration: juvenile TA patients aged ≤ 18 years (n = 17) and adult TA patients aged ≥ 21 years (n = 45). The protocol evaluated the following prognostic factors: aortic insufficiency, ischaemic retinopathy, severe systemic hypertension, and arterial aneurysms. In addition, death and remission [defined as stable disease > 6 months (no complaints without immunosuppressive and prednisone use) and normal erythrocyte sedimentation rate (ESR)] were also analysed. Stenosis and aneurisms were investigated by magnetic angioresonance or arteriography and angiographic classification was defined according to Hata criteria. Results: Mean disease duration was similar in the juvenile and adult TA groups (13.50 ± 10.73 vs. 13.80 ± 7.17 years, p = 0.092) and a trend to a lower predominance of female gender in the juvenile TA group was observed (64.71% vs. 88.89%, p = 0.056). The prognosis was distinct in the two groups, with juvenile patients having a lower frequency of disease remission (23.53% vs. 55.56%, p = 0.04) and a significantly higher frequency of aneurism (41.0% vs. 11.1%, p = 0.013). Almost half of the juvenile TA patients had left renal stenosis, a frequency significantly higher than in the adult TA group (41.18% vs. 11.10%, p = 0.013), whereas the stenosis frequency was comparable in all other vascular sites evaluated. No differences were observed between the two groups regarding the frequency of aortic insufficiency, ischaemic retinopathy, severe systemic arterial hypertension, vascular procedures, and mortality. Angiographic classification revealed a similar distribution of arterial involvement in both groups (p > 0.05). Conclusions: Juvenile TA patients have distinct characteristics, with a peculiar renal vascular involvement, the presence of aneurism, and a more refractory disease compared with adult TA patients.

OBJECTIVE: The novel description of antibodies to lipoprotein lipase (anti-LPL) associated with dyslipoproteinemia prompted us to analyze the association of anti-LPL with clinical and serologic features in patients with systemic lupus erythematosus (SLE) and its link to markers of inflammation that are known to be involved in atherogenesis. METHODS: Enzyme-linked immunosorbent assay was used to test for the presence of anti-LPL antibodies in 66 consecutive patients with SLE. Clinical and laboratory evaluation, including a fasting lipid profile, autoantibody screening, an assessment for markers of inflammation (C-reactive protein [CRP], erythrocyte sedimentation rate [ESR]), and the SLE Disease Activity Index (SLEDAI) were performed at the time of inclusion in the study. Exclusion criteria were any conditions that affect the lipid profile. SLE patients were categorized into 2 groups according to detection of these anti-LPL antibodies, as follows: anti-LPL+ and anti-LPL-. RESULTS: Anti-LPL antibody IgG was detected in 25 SLE patients (37.8%). Triglyceride levels were significantly higher in the anti-LPL+ group (112.4 +/- 50.2 versus 89.9 +/- 54.5 mg/dl in the anti-LPL- group; P = 0.033), but no significant differences between the 2 groups were detected for total, high-density lipoprotein, and low-density lipoprotein cholesterol levels. A higher frequency of elevated CRP levels and ESRs was observed in the anti-LPL+ group compared with the anti-LPL- group (44% and 17.1%, respectively [P = 0.023] and 52% and 19.5%, respectively [P = 0.013]). Moreover, SLE patients with anti-LPL antibodies also had significantly higher levels of CRP (11.1 +/- 16.4 versus 2.4 +/- 2.6 mug/ml; P = 0.036) and higher ESRs (33.4 +/- 29.8 versus 16.5 +/- 11.8 mm/hour; P = 0.020). Anti-LPL titers had a significant positive correlation with the CRP level (r = 0.56, P < 0.001), the ESR (r = 0.55, P < 0.001), the SLEDAI score (r = 0.45, P < 0.001), anti-double-stranded DNA (anti-dsDNA; r = 0.52, P < 0.001), and anticardiolipin IgG antibodies (r = 0.25, P = 0.04), and a significant negative correlation was detected with total hemolytic complement activity (CH100) (r = -0.34, P = 0.005). Reinforcing these findings, multiple regression analysis also revealed a significant association of anti-LPL with the CRP level (P = 0.025) and anti-dsDNA (P < 0.001). Importantly, a comparison of positive and negative anti-dsDNA sera revealed similar mean CRP levels (P = 0.56) and ESRs (P = 0.102), contrasting with the SLEDAI score (P = 0.004) and CH100 (P = 0.008). CONCLUSION: These data support the link between inflammation, immune response, and dyslipoproteinemia in SLE, introducing anti-LPL as a possible new player that may ultimately help in understanding the complex events of atherogenesis in this disease.
