BACKGROUND: Microvascular changes play a decisive role in systemic sclerosis (SSc) and occur early in the course of the disease. Pulmonary arterial hypertension (PAH) represents one of the main clinical expressions of the vascular changes in SSc, and the abnormal changes especially capillary density and capillary width are detectable at nailfold videocapillaroscopy (NVC). AIM: The aim of this meta-analysis was to investigate the differences in capillary nailfold changes in SSc patients with and without PAH, and to estimate the early diagnostic value of NVC in systemic sclerosis secondary pulmonary arterial hypertension (SSc-PAH)...

A 69-year-old woman with asthenia, anorexia and weight loss lasting for several weeks was referred for a subacute onset of painful permanent acrocyanosis of the four extremities without Raynaud's phenomenon. She also had concomitantly developed grade I/IV (NYHA) dyspnea. A physical examination revealed livedoid acrocyanosis of distal phalanges of the hands (Fig. 1A), which was associated with flame-shaped hemorrhages (Fig. 1B, arrow-head), dilated capillaries at the proximal nailfolds (Fig. 1B, arrow), Gottron's sign over the MCP and PIP joints and a discrete heliotrope rash with a palpable V-shaped rash of the upper chest and forehead...

BACKGROUND/AIMS: An altered haemodynamic profile for various ocular posterior segment capillary beds has been documented in primary open-angle glaucoma (POAG). POAG may also involve abnormal non-ocular blood flow, and the nailfold capillaries, which are not affected by elevated intraocular pressure (IOP), are readily assessable. METHODS: We measured resting nailfold capillary blood flow in 67 POAG and 63 control subjects using video capillaroscopy. Masked readers tracked blood column voids between consecutive, registered image sequence frames, measured vessel diameter and calculated blood flow...

Microcirculation influences peripheral vascular resistance and therefore contributes to arterial blood pressure. The aim of this study was to investigate the correlation between serum markers of inflammation and microcirculatory parameters observed by nailfold videocapillaroscopy (NVC) in patients with resistant (RH, 58 [50-63] years, n = 25) or mild-to-moderate hypertension (MMH, 56 [47-64] years, n = 25) compared to normotensive patients (control group (CG), 33 [27-52] years, n = 25). C-reactive protein (CRP), endothelin, adiponectin, I-CAM and V-CAM levels were obtained by laboratory analysis...

In five patients who suffered from chronic venous insufficiency clinical stage C4 (n = 3) and C6 (n = 2) the capillary blood pressure was measured twice by means of invasive direct cannulation of nailfold capillaries of the toe. During one measurement course the patients wore below knee medical compression stockings (40 mmHg) during the other they did not have compression therapy. With the patient in supine position, the CP was investigated by the servo-nulling technique under resting conditions and under dynamic conditions: the calf-muscle/ankle joint venous pump was simulated by means of inflating a blood pressure cuff, which surrounded the mid lower leg, to 60 mmHg for 60 s...

OBJECTIVES: Despite increasing interest in nailfold capillaroscopy, objective measures of capillary structure and blood flow have been little studied. We aimed to test the hypothesis that structural measurements, capillary flow, and a combined measure have the predictive power to separate patients with systemic sclerosis (SSc) from those with primary Raynaud's phenomenon (PRP) and healthy controls (HC). METHODS: 50 patients with SSc, 12 with PRP, and 50 HC were imaged using a novel capillaroscopy system that generates high-quality nailfold images and provides fully-automated measurements of capillary structure and blood flow (capillary density, mean width, maximum width, shape score, derangement and mean flow velocity)...

BACKGROUND: Nailfold capillaroscopy (NC) is an important diagnostic tool in systemic sclerosis (SSc). Confirmation of NC as a prognostic factor could facilitate earlier intervention and slow disease progression in SSc. We undertook a systematic literature review to evaluate the prognostic value of NC in predicting SSc disease progression. METHODS: Standardised searches of EMBASE and MEDLINE were undertaken to identify longitudinal studies of adult subjects with SSc reporting the prognostic value of NC for any aspect of disease progression and/or survival...

White-blood-cell (WBC) assessment is employed for innumerable clinical procedures as one indicator of immune status. Currently, WBC determinations are obtained by clinical laboratory analysis of whole blood samples. Both the extraction of blood and its analysis limit the accessibility and frequency of the measurement. In this study, we demonstrate the feasibility of a non-invasive device to perform point-of-care WBC analysis without the need for blood draws, focusing on a chemotherapy setting where patients' neutrophils-the most common type of WBC-become very low...

OBJECTIVE: In SSc, vascular injury leads to endothelial dysfunction with reduced capillary blood flow and tissue hypoxia. In SSc, the angiogenesis is impaired and implicated in the microvascular damage. In severe vascular damage, VEGF is reduced and endostatin is increased. The aim of this study was to evaluate the correlation between endostatin serum levels and microvascular and digital arteries damage. METHODS: Seventeen patients with SSc were enrolled in this study...

BACKGROUND: Absolute nailfold capillary number should be a putative biomarker in selected rheumatic diseases but could be time-consuming and not highly repeatable. OBJECTIVE: To validate an automated software for absolute nailfold capillary number and density evaluation, on NVC images in SSc. METHODS: An automated software to count nailfold capillary number (AUTOCAPI) had been constructed, through an exploratory image set. Subsequently, application rules have been created to define the ROI in NVC images, through a training images set...

Most patients with Raynaud's phenomenon (RP) have "benign" primary RP (PRP), but a minority have an underlying cause, for example a connective tissue disease such as systemic sclerosis (SSc). Secondary RP can be associated with structural as well as functional digital vascular changes and can be very severe, potentially progressing to digital ulceration or gangrene. The first step in management is to establish why the patient has RP. This short review discusses the role of nailfold capillaroscopy and thermography in the assessment of RP...

Nailfold capillaroscopy is an easy, non-invasive technique to assess microvascular involvement in rheumatic diseases. Multiple studies describe capillaroscopic changes in systemic lupus erythematosus (SLE), including a wide range of non-specific findings. On behalf of the European League Against Rheumatism (EULAR) study group on microcirculation in rheumatic diseases, a systematic review was done to obtain all original research studies (in English) in which SLE patients had capillaroscopy. Forty such studies are identified...
