Abstract
OBJECTIVES Systemic vasculitides (SVs) are a highly inflammatory group of diseases characterized by significant cardiovascular (CV) mortality. Microvascular damage closely linked with accelerated atherosclerosis and thrombosis represents a core pathophysiological mechanism contributing to the excess CV risk of patients with SVs. Skin represents an easily accessible tissue facilitating non-invasive microvascular study. In this study we aimed to investigate microcirculation dynamics and associate them with disease-related factors in patients with SVs. METHODS We assessed skin microcirculation using laser speckle contrast imaging (LSCI) and vascular reactivity by the post-occlusive reactive hyperaemia (PORH) protocol in a meticulously selected group of patients with SVs without CV disease and compared them to controls, matched for age, sex, BMI and smoking status. RESULTS Sixty individuals were included in the study, 30 patients and 30 controls. Patients with SVs presented a lower peak magnitude during reperfusion phase (median [interquartile range] 207 [60.1] vs 143.7 [41.0] laser speckle perfusion units, P < 0.001) and lower percentage cutaneous vascular conductance increase (mean (s.d.) 190.0 [49.6]% vs 149.6 [48.9]%, P = 0.002) as compared with controls. Importantly, microvascular damage was correlated with disease duration (P < 0.001, r = -0.563 and P < 0.001, r = 0.442, respectively). CONCLUSION For the first time we have shown that patients with SVs exhibit impaired microvascular function and blunted reactivity after occlusion, as this was demonstrated by the LSCI technique. Therefore, skin microcirculation may be a useful, non-invasive method in patients with SVs for the early detection of microvascular dysfunction, which is closely related to the high CV risk that these patients bear.

Abstract
OBJECTIVES Nailfold video-capillaroscopy (NVC) is an inexpensive method of assessing microcirculation. We reviewed the literature to assess whether changes to the nailfold capillaries exist in patients with cardiovascular disease (CVD). METHODS We searched PubMed, Scopus and Cochrane Library databases for original research articles relating to the use of noninvasive microvascular assessment in patients with CVD. Methodological quality was assessed with the 'Quality Assessment Tool for Observational Cohort and Cross-sectional Studies.' The results obtained from NVC were analysed qualitatively and compared with other forms of microvascular assessment. RESULTS In total 2759 articles were screened, of which 22 studies involving 562 patients (~40% women) with CVD were included. Mean age ranged between 3.7-68.4 years (cases) and 4.0-58.0 years (controls). Reduced capillary density and increased capillary dimensions were seen in patients with pulmonary arterial hypertension (PAH). Among patients with systemic sclerosis, advanced scleroderma patterns can be used to identify patients with or at risk of developing PAH. Functional nailfold changes precede structural changes in patients with hypertension. However, the studies were heterogeneous in the diagnosis of disease and the measurement of nailfold parameters. Most studies did not exclude conditions with altered nailfold features, and only one study performed a power calculation. Furthermore, abnormal nailfold findings are present in patients without systemic disease. CONCLUSIONS Structural and functional changes to the nailfold are a feature of established CVD and precede the development of PAH. However, heterogeneity in measurement and abnormal findings in healthy participants limit their use in the wider population.

Abstract
BACKGROUND Interleukin 37 (IL-37) is an anti-inflammatory cytokine previously studied in Behçet's disease (BD) and atherosclerosis. However, little is known about its relation to macro and microcirculations in BD. Previous studies relied mainly on common carotid artery (CCA) intima-media thickness (IMT) and ankle brachial index (ABI) to study atherosclerosis in BD with conflicting results. This study evaluated flow parameters of CCA, ABI and nailfold videocapillaroscopy in relation to serum IL-37 in BD. METHODS Forty BD patients and 30 healthy controls were included. IMT, peak-systolic, end-diastolic velocities, resistivity index of CCA and ABI were measured by duplex ultrasound. Capillary loop, length, diameter and morphology were recorded by nailfold videocapillaroscopy. Serum IL-37 levels were measured using enzyme-linked immunosorbent assay (ELISA). RESULTS Compared to controls, patients had higher mean CCA IMT (p < 0.0001), resistivity index (p < 0.001) and peak-systolic velocity (p=0.09) and lower mean CCA end-diastolic velocity (p=0.002), capillary loop, length, arterial, venous limbs diameter and serum IL-37 (p < 0.001). Patients with ABI ≥ 1.4 "indicating stiff arteries" had higher serum IL-37 (p < 0.05 on left, p>0.05 right sides). Serum IL-37 correlated negatively with left CCA end-diastolic velocity "denoting atherosclerosis" and positively with left posterior tibial artery ABI and CRP (p < 0.03) "denoting inflammation". Multiple regression analysis showed only association with left CCA end-diastolic velocity. CONCLUSIONS IL-37 may be related to arterial stiffness in BD and could be used as a possible marker of arteriosclerosis in the disease for further investigations. Changes of CCA peak-systolic, end-diastolic velocities, resistivity index and IMT refer to increased atherosclerosis in larger elastic arteries. In smaller muscular "crural" arteries, vasculitis with possible medial disease may be more evident.

Abstract
Nail fold is one of the most accessible sites for studying changes in the microcirculation in various microangiopathies. The characterization of changes in microvasculature can provide useful clues towards the diagnosis and prognosis of a disease. The diagnostic utility of nail fold capillaroscopy has improved and expanded over the past couple of decades. Beyond connective tissue diseases, it is now explored for its role in various systemic and dermatological diseases. Incorporation of nail-fold capillaroscopy in the diagnostic criteria of systemic sclerosis has generated interest among dermatologists. The current review is aimed at providing knowledge about nail-fold capillaroscopy to dermatologists. For the purpose of review, a PubMed search was done using the keywords "nail fold capillaries" and "nail fold capillaroscopy". All the articles were retrieved and classified into reviews and clinical studies of various types. The final data were then analyzed and presented in a narrative fashion.

Abstract
BACKGROUND Microvascular dysfunction is one of the pathophysiological mechanisms in heart failure. Nailfold videocapillaroscopy is a noninvasive technique used to examine the microvasculature. OBJECTIVE In this study, we aimed to investigate the nailfold capillaroscopic abnormalities in heart failure patients with reduced and preserved ejection fraction and compare those with control group. METHODS Three groups of patients were recruited for the study: HFrEF group includes the patients with heart failure with reduced ejection fraction (HFrEF), HFpEF group, patients with heart failure with preserved ejection fraction (HFpEF) and control group, healthy asymptomatic individuals. Nailfold videocapillaroscopy was performed with a videodermatoscope and all nailfold images were evaluated for enlargement and hemorrhages. RESULTS Abnormal videocapillaroscopic findings including enlargement and/or hemorrhages were present in 7 (24%) patients in HFrEF group, 19 (66%) patients in HFpEF group and 11 (37%) in control group. The number of patients with abnormal videocapillaroscopic findings were significantly greater in HFpEF group compared to HFrEF (p < 0.05) and control groups (p < 0.05). However, no significant difference was observed in videocapillaroscopic findings between HFrEF and control groups. CONCLUSIONS Our study showed that microvascular abnormalities demonstrated by videodermatoscopic examination of nailfold capillaries are considerably more common in HFpEF patients compared to HFrEF and control groups.

Abstract
BACKGROUND Nailfold capillaroscopy is a highly sensitive, inexpensive, simple, safe, and noninvasive technique used in the investigation of the microcirculation. However, the diseases having a vasculitic component can cause changes in the nailfold capillaries like viral hepatitis, the microvascular characteristics of the nailfold area in HBV and HCV infected individuals have not been systematically investigated. In this study, we investigated possible dermoscopic differences in the vascular appearance of the nailfold capillaries and their association with the disease's clinical status. METHOD A hundred and forty-seven patients and 147 healthy controls were enrolled in this study. The patients' group consisted of chronic viral hepatitis B (CHB: 54 cases), chronic hepatitis C (CHC: 36 cases) and carrier of hepatitis B virus infection (CRHB: 57 cases). Nailfold capillaroscopy was performed using a digital dermoscope (Molemax II, X30). All capillaroscopy images were evaluated for capillary density, capillary loop enlargement, capillary tortuosities, branching vessels, micro hemorrhages, avascular areas and splinter hemorrhages, and routine laboratory examinations of all patients were performed. RESULTS Statistical differences in all of the categories of capillary morphology were prominent between the capillary abnormalities of Hepatitis B and the control group, also the capillary abnormality was significant between hepatitis C and the control group (p < 0.01). None of the 147 healthy control had any nailfold capillary changes. There was a significant difference between the CHB-Control and CRHB-Control groups in all of the capillaroscopic changes (p < 0.01). The avascular area was also the most common finding in Hepatitis C and Hepatitis B infected individuals, and capillary dilatation (CD), capillary tortuosity (CT) and capillary enlargement (CE) were the major nailfold capillary changes in both of two diseases. CONCLUSION Nailfold capillary abnormalities are one of the extrahepatic dermatologic finding which could be a sign of the endothelial tissue damage in chronic viral hepatitis, we do not have any data about the effects of these two usual infections on the nailfold capillary morphology. This is the first study evaluating the microvasculature abnormalities of the nailfold capillaries in hepatitis B and hepatitis C infected individuals by capillaroscopic examination.

Abstract
Background/aim Abnormal capillaroscopic findings have been reported in vasculitic syndromes such as Behçet’s disease, Henoch–Schönlein purpura, and Wegener’s granulomatosis. This study was conducted to define the capillaroscopic changes in patients with Takayasu arteritis (TA). Materials and methods We studied 28 TA patients (27 females). The nail folds from the 2nd to 5th fingers on both hands were examined with video capillaroscopy for all. A patient was defined as having an abnormal capillaroscopic examination if more than 1 morphologic abnormality was present in at least 2 nail folds. Results The median capillary density of TA patients was 9 (range: 9–11). There were no patients with capillary disorganization or avascular areas. Tortuous capillaries were detected in all patients. The other common morphological capillary abnormalities included enlarged/dilated capillaries (39.3%), branching capillaries (35.7%), and hemorrhages (32.1%). Only 1 patient had giant capillaries with early scleroderma-like pattern. Overall, there were 11 (39.3%) patients with abnormal capillaroscopic findings. There were more patients with abnormal capillaroscopic findings in the subgroup of TA patients whose upper extremity blood pressure could not be measured as compared to those whose blood pressure could be measured (66.7% vs. 26.3% patients; P = 0.04). Conclusion Capillaroscopic abnormalities are frequently seen in TA patients. We consider that abnormal capillaroscopic findings in TA patients reflect the impaired blood flow due to narrowed or occluded arteries rather than the primary capillary involvement of the disease process.

Abstract
PURPOSE We performed nailfold capillary microscopy to explore microvasculature abnormalities in uveitis overall and uveitis stratified in various ways. METHODS This was a cross-sectional, case-control, observational study. One hundred and seven uveitis patients and 130 control subjects were included. We used a JH-1004 capillaroscope to perform nailfold capillary video microscopy on the fourth and fifth digits of each subject's nondominant hand. Videos were evaluated for hemorrhages, dilated capillary loops > 25 µm, and avascular zones > 200 µm. Univariate analyses were used for the assessment of case-control morphological differences and multivariate analyses were performed to assess the relation between nailfold capillaroscopic findings and uveitis subgroups. RESULTS In univariate analysis, uveitis patients were more likely to have higher tortuosity ratings and reduced capillary density compared to controls (p < 0.001 for both); furthermore, dilated capillary loops, avascular zone and hemorrhages were more frequent in uveitis versus control subjects (p < 0.001 for all). Among cases, every unit increase in capillary density (vessels/mm) was associated with active uveitis (n = 72 cases) versus inactive disease (n = 35 cases; odds ratio (OR) = 1.7; (95% confidence interval (CI), 1.2-2.5) in multivariate analysis. Furthermore, the presence of any nailfold hemorrhage versus the absence of hemorrhage was more likely to be associated with posterior and panuveitis (n = 41 cases combined) compared to anterior and intermediate uveitis (n = 66 cases combined; OR = 5.8; 95% CI, 2.3-14.2). Moreover, we found a positive correlation between peripheral retinal leakage and nailfold capillaries dilation (r = 0.33; p = 0.015) that was not strictly significant based on the number of comparisons made. CONCLUSIONS Our study provides support for non-ocular capillary bed abnormalities in uveitis, with interesting correlations based on disease stage and anatomical classification.

Abstract
BACKGROUND Nailfold videocapillaroscopy (NVC) is a diagnostic tool to evaluate micro-vasculature. The presence of choroidal vasculopathy is apparent in central serous chorioretinopathy (CSCR). OBJECTIVES This study was aimed at assessing capillaroscopic nailfold findings in patients with CSCR. To the best of our knowledge, there is no study assessing NVC findings in CSCR in the literature. METHOD Sixty-one patients with CSCR who met the inclusion criteria, and 82 age- and sex-matched healthy controls were included to the study. A videocapillaroscopy device with 200× magnification was used for capillaroscopic assessment. RESULTS The mean age was 48.79 ± 11.15 years in the patient group (13 female, 48 male) and 49.38 ± 9.02 years in the control group (17 female, 65 male). The age and gender were comparable in the patient and control groups (p = 0.727 and p = 0.933, respectively). The capillary count was found to be decreased in the patient group compared to control group. No significant correlation was found between capillary count and choroidal thickness (p = 0.551; r = -0.081). In the patient group, the frequencies of major capillaroscopic findings including capillary ectasia, aneurysm, micro-hemorrhage, avascular area, tortuosity, neo-formation, bizarre capillary, bushy capillary, meander capillary and extravasation were found to be increased in the patient group. However, no significant correlation was detected between capillaroscopic findings and disease type and presence of attacks. CONCLUSIONS This is first study in which nailfold capillary assessment was performed in patients with CSCR, and we detected major capillaroscopic changes. These findings suggest that CSCR can be a systemic microvasculopathy. Further studies are needed to clarify the diagnostic and prognostic value of capillaroscopy in CSCR.
