Asymptomatic Coronary Artery Calcifications in Men with Systemic Lupus Erythematosus.

OBJECTIVE: To determine whether the prevalence and extent of asymptomatic coronary artery atherosclerosis are increased in men with systemic lupus erythematosus (SLE) compared with age- and sex-matched controls, and to define the associated risk factors. METHODS: Ninety-five patients with SLE (mean ± SD age, 34.7 ± 10.1 yrs) and 100 control subjects (age 34.8 ± 9.7 yrs) with no history of coronary artery disease were screened for coronary artery calcification using multidetector computed tomography. The extent of calcification was measured using the Agatston score. The frequency of risk factors for calcification was compared between patients and controls, and the relationship between clinical and immunological characteristics and the presence of coronary artery calcification was investigated. RESULTS: Coronary artery calcification was more frequent in patients than controls [18% vs 7%, respectively (OR 2.89, 95% CI 1.07-8.65)]. These factors were independently associated with the presence of calcifications: age (OR 1.12, 95% CI 1.04-1.20), SLE diagnosis (OR 3.38, 95% CI 1.07-10.64), diabetes mellitus (OR 6.88, 95% CI 1.50-31.62), Framingham risk score (OR 1.12, 95% CI 1.00-1.23), and glomerular filtration rate (OR 0.98, 95% CI 0.96-1.00). Among patients with SLE, coronary artery calcifications were observed starting at age 32 years, within 2.3 years of diagnosis. Increasing age (OR 1.18, 95% CI 1.06-1.31), Systemic Lupus International Collaborating Clinics score (OR 2.85, 95% CI 1.21-6.73), and cumulative dose of prednisone (OR 1.04, 95% CI 1.01-1.08) were independent risk factors. CONCLUSION: Men with SLE are at an increased risk of coronary artery calcifications than age- and sex-matched controls. Among patients with SLE, the increased risk is associated to older age, increasing chronic damage, and cumulative dose of corticosteroids.

Defecto de la tabicación atrioventricular con 2 válvulas asociado a ausencia del pericardio: Informe de un caso / Atrioventricular defect with 2 valves associated with absence of the pericardium: Report of a case

Presentamos el caso de una paciente con una malformación cardiaca que representa una forma de transición anatomoembriológica del defecto de la tabicación atrioventricular entre la forma de 2 válvulas y la que tiene una válvula común. Esta entidad además se asoció con ausencia de pericardio. A través de los diferentes estudios se ha establecido con precisión la secuencia diagnóstica, determinando cuál fue la aportación de cada método y aclarando además la nomenclatura del defecto de la tabicación atrioventricular.

We present a case of a patient with a cardiac malformation that represents a form of embryo-anatomical transition of an atrioventricular septal defect between a 2 valves form to a common valve form. This entity was associated with pericardium absence. Throughout several studies we have precisely established a diagnostic sequence by determining the adequate contribution of each method and we have been able to clear out the proper nomenclature of the atrioventricular cushion defect.

Systemic lupus erythematosus risk factors for coronary artery calcifications.

OBJECTIVE: Premature atherosclerosis in patients with SLE is partially explained by traditional risk factors; therefore, we aimed to identify lupus-related risk factors for coronary artery calcifications. METHODS: An inception cohort of 139 lupus patients (93% females) was screened for coronary artery calcifications using Multidetector CT, after 5.1 years of follow-up. Clinical and immunological variables and cardiovascular risk factors were assessed longitudinally. Also, 100 age- and sex-matched healthy subjects were studied. Correlates for calcifications were analysed in lupus patients, including levels of lipids and inflammatory molecules in samples obtained at enrolment, mid-term follow-up and at screening. RESULTS: At enrolment, lupus patients were 27.2 (9.1) years of age and with a disease duration of 5.4 (3.8) months. Calcifications were detected in 7.2% of patients and 1% of controls [unadjusted odds ratio (OR) 7.7, 95% CI 1.05, 336.3, P = 0.02]. In lupus, calcifications were detected since the age of 23 years and from 3 years of diagnosis. Patients with calcifications were older, post-menopausal, and had higher levels of serum apolipoprotein B and Framingham risk scores (P < 0.05). Lupus-related factors identified included age at diagnosis, IgG aCLs, cumulative lupus activity, length of moderate/severe activity and cumulative dose of prednisone and CYC (P < 0.05). Use of anti-malarials was protective (P = 0.006). Logistic regression analysis showed as predictors of calcification: disease duration (OR 15.1, 95% CI 2.6, 87.2), age at enrolment (OR 8.5, 95% CI 1.7, 43.0) and SLEDAI 2000 update (SLEDAI-2K) mean area under the curve (OR 12.3, 95% CI 2.5, 61.8). Longitudinal analyses of lipids and inflammatory molecules did not differ between patients. CONCLUSIONS: Disease activity is a potentially modifiable risk factor for coronary artery calcifications in SLE. Therefore, management of traditional risk factors plus tight control of lupus activity, including the use of anti-malarials, is recommended.
