INTRODUCTION AND AIM: Endothelial microparticles (EMPs) are membrane-coated vesicles shed from endothelial cells and are considered markers of the endothelial state. It has been shown that total numbers of circulating EMPs are increased in patients with systemic sclerosis (SSc), but their clinical correlations have not yet been investigated in detail. We aimed to assess possible relationships between circulating EMPs and clinical as well as laboratory features among SSc patients with special attention to possible association with alteration in microvascular morphology objectified on nailfold videocapillaroscopy and clinical signs of microvascular complications...

Obesity is a crescent epidemic in the world, affecting more than half a billion of adults worldwide. Obesity is associated to main cardiovascular risk factors, such as insulin resistance, type 2 diabetes mellitus, high blood pressure and dyslipidemia. The excessive adiposity causes a dysregulation of adipokines secretion by adipose tissue, upregulating the expression of pro-inflammatory adipokines and downregulating the anti-inflammatory ones. This scenario contributes for the appearance of atherosclerosis...

OBJECTIVE: Systemic sclerosis (SSc) is a well-established disease associated with primary biliary cholangitis (PBC). However, the original 1980 American College of Rheumatology (ACR) criteria have poor sensitivity, especially for the detection of earlier SSc in previous studies. The objective was to evaluate the prevalence of SSc in patients with PBC using more sensitive 2001 LeRoy and Medsger criteria and the 2013 ACR/European League Against Rheumatism (EULAR) classification criteria...

Nailfold capillaroscopy is one of the various noninvasive bioengineering methods used to investigate skin microcirculation. It is an effective examination for assessing microvascular changes in the peripheral circulation; hence it has a significant role for the diagnosis of Systemic sclerosis with the classic changes of giant capillaries as well as the decline in capillary density with capillary dropout. The decline in capillary density is one of microangiopathic features existing in connective tissue disease...

CXCL4 is an antiangiogenic and immunomodulatory chemokine. We aimed to investigate serum levels of CXCL4 in primary Sjögren's syndrome (pSS), looking for associations with disease features. Thirty-nine consecutive pSS patients underwent clinical-serological assessment and nailfold videocapillaroscopy (NVC). Thirty-six patients and 30 controls affected by osteoarthritis were also investigated for serum levels of CXCL4 and soluble E-selectin (sE-selectin). CXCL4 was higher in pSS patients than in controls (1...

Micro- and macrovascular pathology is a frequent finding in a number of common rheumatic diseases. Secondary Raynaud's phenomenon (RP) is among the most common symptoms in systemic sclerosis and several other systemic autoimmune diseases including a broad differential diagnosis. It should be also differential from other peripheral vascular syndromes such as embolism, thrombosis, etc., some of which lead to clinical manifestation of the blue toe syndrome. The current review discusses the instrumental methods for vascular assessments...

Capillaroscopy is a non-invasive, easy and safe diagnostic technique designed to evaluate small vessels of the microcirculation in the nailfold. It can reveal both the general architecture of capillary rows and fine details of particular vessels. The most important indications for performing capillaroscopy include differential diagnosis of primary and secondary Raynaud's phenomenon, as well as assessment of scleroderma spectrum disorders. In systemic sclerosis capillary abnormalities appear and evolve in a clearly defined sequence called the scleroderma pattern, which correlates with internal organ involvement...

OBJECTIVE: To validate the 2013 ACR/EULAR classification criteria for systemic sclerosis (SSc) in patients from a capillaroscopy clinic. METHODS: All patients attended in a capillaroscopy clinic were included. Sociodemographic and SSc-related variables were collected. Using as gold standard for SSc the clinical judgement, the performance (sensitivity, specificity, predictive values, and likelihood ratios) of the 2013 ACR/EULAR criteria were analyzed. Receiver operating characteristic (ROC) curve and the area under the curve (AUC) were calculated for the global score and individual items, and the best cutoffs were obtained...

Importance: Vasculopathy characterized by functional and structural abnormalities of the microcirculation plays an important role in systemic sclerosis and dermatomyositis. Although there are several advantages in using capillaroscopy, the method does not offer insight on the skin architecture, flow status, or morphology of the deeper dermal vessels. Dynamic optical coherence tomography (D-OCT) is a recently developed OCT technique that enables detection of high-speed changes in back-scattered light caused by moving cells in vessels...

OBJECTIVE: Digital ulcers (DU) are the most common vascular complication of systemic sclerosis (SSc). We compared the characteristics between patients with prior or current DU with those never affected and evaluated whether a history of DU may be a predictor of vascular, organ involvement, and/or death in patients with SSc. METHODS: Data from SSc patients with or without prior or current DU were collected by 19 referral centers in an ongoing registry of Spanish SSc patients, named Registro de ESCLErodermia (RESCLE)...
