Vascular Involvement in Rheumatoid Arthritis

Rheumatoid arthritis (RA) represents the one of the most common inflammatory rheumatic diseases, which generates disability and significantly reduces the quality of life. RA can affect the vascular system, in addition to joint involvement. Vascular involvement increases the morbidity and mortality among these patients. Macrovascular disease, related to accelerated atherosclerosis, has a high prevalence among RA patients, in the form of carotid artery disease, ischemic heart disease, and peripheral arterial obstructive disease. Microvascular disease, studied in recent years by means of nailfold capillaroscopy, is present even in the early stage of RA evolution. Rheumatoid vasculitis can occur in severe forms of RA

LUPUS NEPHRITIS AND PREGNANCY. THE RHEUMATOLOGIST’S OPINION

In the presence of lupus nephritis, the pregnancy remains a challenging problem, requiring a multidisciplinary monitoring. Such pregnancies are considered as high risk similar to those with maternal and fetal potential complications. Thus, these pregnancies must be planned, after a multidisciplinary evaluation, performed by obstetrician, rheumatologist and nephrologist. Inactive disease for at least 6 months before conception, absence of hypertension, heavy proteinuria or important renal dysfunction are associated with good maternal-fetal outcomes. Lupus nephritis flare and preeclampsia may occur, associating a poor prognosis. Therapeutic regimens must be adapted, taking into account the teratogenic effects of the drugs

Electrocardiographic Predictors of Cardiovascular Mortality

Cardiovascular diseases are the main causes of mortality. Sudden cardiac death may also appear in athletes, due to underlying congenital or inherited cardiac abnormalities. The electrocardiogram is used in clinical practice and clinical trials, as a valid, reliable, accessible, inexpensive method. The aim of the present paper was to review electrocardiographic (ECG) signs associated with cardiovascular mortality and the mechanisms underlying those associations, providing a brief description of the main studies in this area, and consider their implication for clinical practice in the general population and athletes. The main ECG parameters associated with cardiovascular mortality in the present paper are the P wave (duration, interatrial block, and deep terminal negativity of the P wave in V1), prolonged QT and Tpeak-Tend intervals, QRS duration and fragmentation, bundle branch block, ST segment depression and elevation, T waves (inverted, T wave axes), spatial angles between QRS and T vectors, premature ventricular contractions, and ECG hypertrophy criteria

Pulmonary Involvement in Sjögren’s Syndrome: Correlations with Biomarkers of Activity and High-Resolution Computer Tomography Findings

(1) Background: Sjögren’s syndrome (SS) represents a systemic autoimmune disease whose pathophysiology has yet to be elucidated, though it is known that the inflammatory process encountered in SS is of a systemic nature, with cytokines representing the main mediators for tissue damage. (2) Aim of the study: The aim of the present study is to further the understanding of the link between interleukin serum levels, cytokine serum levels, HRCT findings and the Warrick score (as tools for the evaluation of pulmonary involvement) in patients with pSS. (3) Methods: The present study is a retrospective, observational one aimed at ascertaining the link between SS activity and its clinical implications, as well as how interleukin and TNF-α levels correlate with systemic changes. The study enrolled 112 patients with pSS and 56 healthy subjects, matched for age and gender, as a control group. pSS activity was assessed using the ESSDAI. Cytokine levels and leukocyte and lymphocyte counts were measured in both groups. The focus score was calculated for each patient, HRCT was performed to assess lung function, and the Warrick score was calculated. (4) Conclusions: HRCT revealed NSIP in 13 patients (59.09%) and UIP in 9 patients. The strongest positive correlation was identified upon analyzing the relation between IL-8 and the Warrick score (r = 0.9156, p p p = 0.0433)

Endothelial Dysfunction in Primary Sjögren’s Syndrome: Correlation with Serum Biomarkers of Disease Activity

To assess the relationship between endothelial dysfunction and serum cytokines, anti-SSA and anti-SSB antibodies, beta-2 microglobulin levels, focus score and EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI) in primary Sjögren’s syndrome (pSS) patients. The study included 90 patients with pSS and 45 healthy subjects, matched for age and gender, as controls. Serum beta-2 microglobulin, total cholesterol, HDL-cholesterol, triglycerides, TNF-α, and IL-6 were analyzed in both the groups. Patients with pSS were also tested for antinuclear antibodies, anti-SAA (anti-Sjögren’s syndrome-related antigen A) antibodies, anti-SSB (anti-Sjögren syndrome related antigen B) antibodies, and focus score (the histopathologic one, based on minor salivary gland biopsy). Endothelial dysfunction was assessed by means of flow-mediated dilation (FMD) in the brachial artery. Data are presented as mean ± standard deviation. Statistical analysis was performed using the t-test and the Pearson’s correlation. Differences were considered to be statistically significant if the value of p p p < 0.00001). Endothelial dysfunction (expressed as FMD%) was correlated with focus score, ESSDAI, levels of anti-SSA and anti-SSB antibodies, beta-2 microglobulin, IL-6, and TNF-α, with statistical significance. Endothelial dysfunction is present in pSS patients and is associated with a high focus score and activity as well as increased concentrations of antibodies, pro-inflammatory cytokines, and beta 2-microglobulin

Cardiovascular Risk in Rheumatoid Arthritis

Rheumatoid arthritis (RA), one of the most common inflammatory rheumatic diseases. It is defined as a chronic destructive and deforming arthropathy; it also finds its expression through systemic manifestations. RA has an undulating evolution, with remissions and relapses. Atherosclerotic cardiovascular disease represents one of the most common extra-articular manifestations of RA. It is known that the cardiovascular (CV) morbidity and mortality represent one of the leading causes of reduced life expectancy in RA. Patients with RA develop a premature and accelerated atherosclerosis, explaining the high incidence and prevalence of angina, myocardial infarction, congestive heart failure, stroke, peripheral artery disease, and the need for revascularization. Traditional risk factors (arterial hypertension, obesity, smoking, dyslipidemia, insulin resistance and metabolic syndrome, diabetes mellitus, male gender, physical inactivity) interplay with RA-related risk factors, generating endothelial dysfunction, arterial stiffness, carotid plaque, and atherosclerosis. Traditional cardiovascular risk factors alone cannot explain the increased incidence of premature and accelerated atherogenesis. Chronic inflammation, hyperhomocysteinemia, and hypercoagulation act as novel cardiovascular risk factors. Rheumatoid inflammation exerts direct effects on vessels, or by means of altered traditional risk factors. Antirheumatic drugs may promote atherogenesis or by reducing systemic inflammation may decrease cardiovascular risk. EULAR recommendations require annual cardiovascular risk assessment

Vitamin D Status, Disease Activity, and Endothelial Dysfunction in Early Rheumatoid Arthritis Patients

Cardiovascular diseases represent important complications in rheumatoid arthritis (RA) patients, generated by an accelerated atherosclerosis. The aim of this study is represented by the assessment of the correlations between serum levels of vitamin D, disease activity, and endothelial dysfunction in patients with early RA. Material and Methods. The study was performed on a group of 35 patients with early RA and 35 healthy subjects matched for age and gender, as controls. In all studied subjects, the following were determined: inflammatory markers, insulin resistance, vitamin D levels, and endothelial dysfunction. Statistical analysis were performed using the Student’s t-test and the Pearson’s test. p values of less than 0.05 were considered statistically significant. Results. The group of patients with RA patients presented inflammation, low levels of vitamin D, elevated insulin resistance, and reduced flow-mediated vasodilation, statistically significant compared to the control group (p<0.00001). Significant inverse correlations between the levels of 25(OH) vitamin D and DAS28, respective insulin resistance, and significant positive correlation between 25(OH) vitamin D and endothelial function were demonstrated. Conclusion. In early RA patients with moderate and high disease activity, low serum levels of vitamin D were associated with disease activity, increased insulin resistance, and endothelial dysfunction
