Abstract
BACKGROUND Systemic sclerosis (SSc) is a complex autoimmune connective-tissue disease, characterised by vasculopathy and fibrosis of the skin and internal organs. Activation of microvascular endothelial cells (ECs) causes the intimal hyperplasia that characterises the vascular remodelling in SSc. The most frequent complication of SSc is the development of digital ulcers (DUs). Thymic stromal lymphopoietin (TSLP) may trigger fibrosis and sustain vascular damage. Aim of this study was to evaluate the correlation between serum level of TSLP and DUs. METHODS 75 consecutive SSc patients were enrolled and serum TSLP levels were measured. The presence of history of DUs (HDU) was evaluated. Recurrent new DUs were defined as the presence of at least 3 episodes of DUs in a 12-months follow up period. The risk of developing new DUs was calculated by applying the capillaroscopic skin ulcer risk index (CSURI). RESULTS The median value of TSLP was higher in patients with HDU than patients without HDU [181.67 pg/ml (IQR 144.67; 265.66) vs 154.67 pg/ml (IQR 110.67; 171.33), p < 0.01]. The median value of TSLP was higher in patients with an increased CSURI index than patients without an increased CSURI [188 pg/ml (IQR 171.33; 246.33) vs 159.33 pg/ml (IQR 128.67; 218), p < 0.01]. Kaplan-Meier curves demonstrated that free survival from new DUs was significantly (p < 0.01) lower in SSc patients with increased TSLP serum levels. CONCLUSION TSLP might have a key role in digital microvascular damage of SSc patients.

Abstract
INTRODUCTION Mixed connective tissue disease (MCTD) is a rare systemic disease characterized by overlapping features of systemic lupus erythematosus (SLE), systemic sclerosis (SSc), dermato-/polymyositis (DM/PM), and rheumatoid arthritis (RA). Naifold capillaroscopy (NFC) is a non-invasive test for evaluating the capillaries of the nail shaft used in the diagnosis of rheumatic diseases. OBJECTIVES To determine whether there are characteristic abnormalities in NFC in MCTD patients, and whether the type of NFC lesions correlates with organ involvement in these patients. METHODS Clinical picture and NFC patterns were analyzed in 43 patients with MCTD. Capillaroscopic images were divided into scleroderma-like pattern (SD-like pattern) according to the Cutolo classification, non-specific lesions, and normal images. Relationships between the clinical aspects considered in the MCTD classification criteria and the changes in the capillaroscopic images were evaluated. RESULTS SD-like pattern was present in 20 MCTD patients (46.51%) with a predominance of the "early" pattern. Giant, branched, dilated capillaries and reduced capillary density were found more frequently in MCTD patients compared to the control group (p-values 0.0005, 0.005, 0.02, < 0.0001 respectively). There were associations found between the presence of a reduced number of vessels, avascular areas, and SD-like pattern with the presence of sclerodactyly in MCTD patients (p = 0.002, p = 0.006, p = 0.02, respectively), alongside an association between the presence of branched vessels and the subpapillary plexus with pulmonary arterial hypertension (PAH) (p = 0.04 and p = 0.005, respectively). CONCLUSIONS MCTD patients are significantly more likely to have abnormalities upon NFC. It is worthwhile to perform capillaroscopic examination in MCTD patients. Key Points • Scleroderma-like pattern was found in more than half of the MCTD patients. • Reduced capillary density was found to be a significant predictor of the diagnosis of MCTD. • There were relationships between the presence of reduced capillary density, avascular areas, and SD-like with the presence of sclerodactyly in the MCTD patients. • There was an association between the presence of branched vessels and the visibility of the subpapillary plexus and pulmonary arterial hypertension (PAH).

Retinal Microvasculature in Systemic Sclerosis Patients and the Correlation between Nailfold Capillaroscopic Findings and Optical Coherence Angiography Results. J Clin Med 2024; 13:2025. [PMID: 38610789 PMCID: PMC11012647 DOI: 10.3390/jcm13072025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 03/24/2024] [Accepted: 03/28/2024] [Indexed: 04/14/2024] Open
Abstract
Background: The comparison of retinal perfusion in the eyes of patients with systemic sclerosis (SSc) and in healthy controls using optical coherence tomography angiography (OCTA). The correlation between nailfold capillaroscopy results and OCTA findings among SSc. Methods: The study enrolled 31 patients with systemic sclerosis and 41 healthy controls. OCTA was performed in both groups to assess the retinal vasculature in the superficial (SCP) and deep (DCP) capillary plexuses and the foveal avascular zone (FAZ) area. Nailfold capillaroscopy (NC) was performed in SSc patients and compared to the FAZ area and the superficial and the deep vessel density. Results: In the SSc group, the parafoveal vessel density in DCP was significantly higher in relation to the mean value (p < 0.0001) and in each quadrant of the macula (p < 0.0001) compared to healthy subjects (p < 0.0001). The patients with early scleroderma patterns in capillaroscopy had a larger superficial and deep FAZ (p = 0.0104, p = 0.0076, respectively) than those with active and late patterns. There was a statistically significant difference in the FAZ when comparing early to active (p < 0.0001) and early to late scleroderma patterns (p < 0.0001). A statistically significant difference was found in the type of interstitial lung disease and the deep FAZ area (p = 0.0484). SSc patients with nonspecific interstitial pneumonia (NSIP) had a larger FAZ than those with usual interstitial pneumonia (UIP) (p = 0.0484). Moreover, NSIP cases had a higher parafoveal mean superficial vessel density than those with UIP (p = 0.0471). Conclusions: Our investigation showed that the peripheral microvascular system correlates with ocular microcirculatory impairment. The results indicate the important role of OCTA in the diagnosis, monitoring, and prognosis of microvascular changes in SSc.

Digital Ulcers and Ventricular Arrhythmias as Red Flags to Predict Replacement Myocardial Fibrosis in Systemic Sclerosis. J Clin Med 2023; 13:89.

Abstract
BACKGROUND Cardiac involvement in systemic sclerosis (SSc) affects the prognosis of the disease. Echocardiography is the first line imaging tool to detect cardiac involvement, but it is not able to routinely detect myocardial fibrosis. Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) is the gold standard for replacement myocardial fibrosis assessment, but its availability is currently limited. AIM We aimed to assess the clinical and instrumental parameters that would be useful for predicting the presence of LGE-CMR, to achieve a better selection of patients with SSc that could benefit from third-level CMR imaging. METHODS 344 SSc patients underwent a comprehensive echocardiogram and LGE-CMR on the same day; for 189 patients, a 24 h ECG Holter monitoring was available. RESULTS CMR showed non-junctional replacement myocardial fibrosis via LGE in 25.1% patients. A history of digital ulcers (OR 2.188; 95% C.I. 1.069-4.481) and ventricular arrhythmias at ECG Holter monitoring (OR 3.086; 95% C.I. 1.191-7.998) were independent predictors of replacement myocardial fibrosis. CONCLUSIONS CMR can detect patterns of clinical and subclinical cardiac involvement, which are frequent in SSc. A history of digital ulcers and evidence of ventricular arrhythmias at ECG Holter monitoring are red flags for the presence of replacement myocardial fibrosis in CMR. The association between digital ulcers and myocardial fibrosis suggests that a similar pathological substrate of abnormal vascular function may underlie peripheral vascular and cardiac complications.

Abstract
Systemic sclerosis (SSc) is an autoimmune disease associated with increased mortality and poor morbidity, impairing the quality of life in patients. Whilst we know that SSc affects multiple organs via vasculopathy, inflammation, and fibrosis, its exact pathophysiology remains elusive. Microvascular injury and vasculopathy are the initial pathological features of the disease. Clinically, the vasculopathy in SSc is manifested as Raynaud's phenomenon (reversible vasospasm in reaction to the cold or emotional stress) and digital ulcers due to ischemic injury. There are several reports that medications for vasculopathy, such as bosentan and soluble guanylate cyclase (sGC) modulators, improve not only vasculopathy but also dermal fibrosis, suggesting that vasculopathy is important in SSc. Although vasculopathy is an important initial step of the pathogenesis for SSc, it is still unclear how vasculopathy is related to inflammation and fibrosis. In this review, we focused on the clinical evidence for vasculopathy, the major cellular players for the pathogenesis, including pericytes, adipocytes, endothelial cells (ECs), and myofibroblasts, and their signaling pathway to elucidate the relationship among vasculopathy, inflammation, and fibrosis in SSc.

Abstract
BACKGROUND Microparticles (MPs) are membrane-derived vesicles released from cells undergoing activation or apoptosis with diverse proinflammatory and prothrombotic activities, that have been implicated in the pathogenesis of systemic sclerosis (SSc). We aimed to evaluate the plasma levels of platelet-derived microparticles (PMPs), endothelial cell-derived microparticles (EMPs), and monocyte-derived microparticles (MMPs) in SSc patients, and the association between MPs and the clinical features of SSc. METHODS In this cross-sectional study, 70 patients with SSc and 35 age- and sex-matched healthy controls were evaluated. Clinical and nailfold capillaroscopy (NFC) data were obtained from all patients. Plasma levels of PMPs (CD42+/31+), EMPs (CD105+), and MMPs (CD14+) were quantified by flow cytometry. RESULTS Patients were mainly females (90%), with a mean age of 48.9 years old. PMP, EMP, and MMP levels were significantly increased in SSc patients compared to controls (79.2% ± 17.3% vs. 71.0% ± 19.8%, p = 0.033; 43.5% ± 8.7% vs. 37.8% ± 10.4%, p = 0.004; and 3.5% ± 1.3% vs. 1.1% ± 0.5%, p < 0.0001, respectively). PMP levels were significantly higher in patients with positive anti-topoisomerase-I antibodies (p = 0.030) and in patients with a disease duration > 3 years (p = 0.038). EMP levels were lower in patients with a higher modified Rodnan skin score (p = 0.015), and in those with an avascular score > 1.5 in NFC (p = 0.042). CONCLUSION The increased levels of PMPs, EMPs and MMPs in scleroderma patients might indicate a possible role for these agents in the pathogenesis of this challenging disease.

Abstract
SIGNIFICANCE The capillaries are the smallest blood vessels in the body, typically imaged using video capillaroscopy to aid diagnosis of connective tissue diseases, such as systemic sclerosis. Video capillaroscopy allows visualization of morphological changes in the nailfold capillaries but does not provide any physiological information about the blood contained within the capillary network. Extracting parameters such as hemoglobin oxygenation could increase sensitivity for diagnosis and measurement of microvascular disease progression. AIM To design, construct, and test a low-cost multispectral imaging (MSI) system using light-emitting diode (LED) illumination to assess relative hemoglobin oxygenation in the nailfold capillaries. APPROACH An LED ring light was first designed and modeled. The ring light was fabricated using four commercially available LED colors and a custom-designed printed circuit board. The experimental system was characterized and results compared with the illumination model. A blood phantom with variable oxygenation was used to determine the feasibility of using the illumination-based MSI system for oximetry. Nailfold capillaries were then imaged in a healthy subject. RESULTS The illumination modeling results were in close agreement with the constructed system. Imaging of the blood phantom demonstrated sensitivity to changing hemoglobin oxygenation, which was in line with the spectral modeling of reflection. The morphological properties of the volunteer capillaries were comparable to those measured in current gold standard systems. CONCLUSIONS LED-based illumination could be used as a low-cost approach to enable MSI of the nailfold capillaries to provide insight into the oxygenation of the blood contained within the capillary network.

Abstract
OBJECTIVES Microangiopathy is implicated in the pathogenesis of diabetic vascular complications. Nail fold videocapillaroscopy (NVC) is an easy non-invasive tool of microvasculature assessment. This study compares the NVC changes in adolescents with Type1 diabetes (T1D) to healthy controls and correlates them to diabetic vascular complications. METHODS Hundred thirty-five adolescents with T1D (disease duration 5 years) were compared to 135 matched controls. Diabetes duration, insulin therapy, fundus, and Toronto clinical scoring system (TCSS) were assessed. Fasting lipids, fraction-C of glycosylated hemoglobin (HbA1C), urinary albumin creatinine ratio (UACR), nerve conduction velocity, and NVC were performed. RESULTS NVC changes were found in 120 adolescents with T1D (88.8%). These changes were significantly higher in adolescents with T1D than controls (p < .001). Significant positive relation was found between NVC changes and TCSS (p = .006), diabetes duration (p = .001), HbA1C (0.008), cholesterol (p = .011), LDL (0.016), UACR (p < .001), and nerve conduction velocity (p < .001). Multivariate logistic regression study revealed that diabetic nephropathy and neuropathy were independently associated with NVC changes (p < .001 and p = .007, respectively). CONCLUSION Adolescents with T1D have significantly higher NVC changes than controls. These changes were more evident in those having vascular complications than those without. Thus, NVC can be a potential non-invasive tool for early assessment and follow-up of the microvasculature among adolescents with T1D.

Abstract
Aim: To identify the frequency of scleroderma-type capillaroscopic patterns and evaluate the association of capillaroscopic patterns with clinical parameters, functional status, fatigue, and pain in systemic sclerosis (SSc).
Material and Method: This cross-sectional study included SSc patients consecutively between January 2017 and January 2019. Cutaneous involvement was evaluated with the modified Rodnan skin score (mRSS). The presence of digital ulcers, Raynaud phenomenon, interstitial lung disease, pulmonary hypertension, cardiac, gastrointestinal system (GIS), renal, joint and muscle involvement were recorded. The severity of the Raynaud phenomenon, fatigue, pain, and patient global assessment (PGA) was assessed on the Visual Analogue Scale (VAS). The Health Assessment Questionnaire (HAQ) and the Duruoz Hand Index (DHI) were used to assess physical disability and hand function, respectively. Nailfold videocapillaroscopic examinations of the patients were performed, and they were classified into four groups, including normal/non-specific, early, active, and late scleroderma patterns.
Results: The mean age of 32 patients with SSc (31 female, one male) was 48.93±12.77. Anormal capillaroscopic examination findings were detected in 93.7% of the patients, and the most common capillaroscopic pattern was the active pattern. The comparison of scleroderma pattern groups revealed no difference in age (p=0.224), but disease duration was shorter in the early pattern group (p=0.005). The duration and severity of the Raynaud phenomenon, and mean mRSS were lower in the early pattern group (p=0.004, p=0.009, and p=0.001, respectively). The digital ulcer (p=0.011) and diffuse cutaneous SSc (p=0.016) were more common in the late pattern group. The percentage of pulmonary hypertension (p=0.011), GIS involvement (p

Abstract
Systemic sclerosis (SSc) is a complex autoimmune connective tissue disease with distinct pathological hallmarks (ie, inflammation, vasculopathy, fibrosis) that may predominate at different stages in the disease course with varying severity. Initial efforts to classify patients with SSc identified a subset of patients with very early SSc. These patients possessed signs of SSc (eg, Raynaud phenomenon, SSc specific autoantibodies and/or nailfold capillary abnormalities) without fulfilling complete SSc classification criteria. Recognizing the inherent value in early diagnosis and intervention in SSc, researchers have endeavored to identify risk factors for progression from very early SSc to definite SSc. The present review summarizes the clinical phenotype of patients with very early and early SSc. Through a scoping review of recent literature, this review also describes risk factors for progression to definite SSc with a focus on the specific clinical features that arise early in the SSc disease course (eg, diffuse cutaneous sclerosis, interstitial lung disease, esophageal dysfunction, renal crisis, cardiac involvement). In addition to clinical risk factors, this review provides evidence for how biological data (ie, serological, genomic, proteomic profiles, skin bioengineering methods) can be integrated into risk assessment models in the future. Furthering our understanding of biological features of very early SSc will undoubtedly provide novel insights into SSc pathogenesis and may illuminate new therapeutic targets to prevent progression of SSc.

Abstract
SIGNIFICANCE Measurement and imaging of hemoglobin oxygenation are used extensively in the detection and diagnosis of disease; however, the applied instruments vary widely in their depth of imaging, spatiotemporal resolution, sensitivity, accuracy, complexity, physical size, and cost. The wide variation in available instrumentation can make it challenging for end users to select the appropriate tools for their application and to understand the relative limitations of different methods. AIM We aim to provide a systematic overview of the field of hemoglobin imaging and sensing. APPROACH We reviewed the sensing and imaging methods used to analyze hemoglobin oxygenation, including pulse oximetry, spectral reflectance imaging, diffuse optical imaging, spectroscopic optical coherence tomography, photoacoustic imaging, and diffuse correlation spectroscopy. RESULTS We compared and contrasted the ability of different methods to determine hemoglobin biomarkers such as oxygenation while considering factors that influence their practical application. CONCLUSIONS We highlight key limitations in the current state-of-the-art and make suggestions for routes to advance the clinical use and interpretation of hemoglobin oxygenation information.

Abstract
Systemic sclerosis (SSc, scleroderma) is a complex connective tissue disease whose earliest clinical manifestations are microvascular tone dysregulation and peripheral microcirculatory abnormalities. Following previous evidence of an association between circulating neurovascular guidance molecules and SSc disturbed angiogenesis, here, we measured the levels of soluble neuropilin 1 (sNRP1), semaphorin 3E (Sema3E), and Slit2 by enzyme-linked immunosorbent assay in serum samples from a large case series of 166 SSc patients vs. 110 healthy controls. We focused on their possible correlation with vascular disease clinical features and applied logistic regression analysis to determine which of them could better reflect disease activity and severity. Our results demonstrate that, in SSc: (i) sNRP1 is significantly decreased, with lower sNRP1 serum levels correlating with the severity of nailfold videocapillaroscopy (NVC) abnormalities and the presence of ischemic digital ulcers (DUs); (ii) both Sema3E and Slit2 are increased, with Sema3E better reflecting early NVC abnormalities; and (iii) higher Sema3E correlates with the absence of DUs, while augmented Slit2 associates with the presence of DUs. Receiver operator characteristics curve analysis revealed that both circulating sNRP1 and Sema3E show a moderate diagnostic accuracy. Moreover, logistic regression analysis allowed to identify sNRP1 and Sema3E as more suitable independent biomarkers reflecting the activity and severity of SSc-related peripheral microvasculopathy.

Abstract
Systemic sclerosis is an autoimmune disease characterized by organ fibrosis and vasculopathy. Almost all patients suffer from Raynaud’s phenomenon. Nailfold video capillaroscopy is the most widely imaging technique available, but flow quantification is impossible. Therefore, novel imaging techniques are of interest. We performed a single-center feasibility study using Microvascular Imaging (MVI) for flow quantification of small fingertip vessels. We compared 20 healthy controls (HCs) with 20 systemic sclerosis (SSc) patients. In HCs, measurements were, on average, statistically significantly higher when combined for all fingers (median 10.68 vs. 6 cm/s, Δ = 4.68 cm/s, p < 0.0001) and for individual fingers. An optimal cut-off value of peak systolic (PS) velocity of <6.13 cm/s and end-diastolic (ED) velocity of <2.13 cm/s discriminated HCs from SSc. Test characteristics for PS showed excellent sensitivity (0.90, 95% CI 0.70–0.98) and specificity (0.85, 95% CI 0.64–0.95; LR + 6.0). For ED velocity, sensitivity was 0.85 (95% CI 0.64–0.95) and specificity was 0.80 (95% CI 0.58–0.92, LR + 4.25). Here, we present the first study on the use of MVI to assess blood flow in the fingertips with high sensitivity and specificity in SSc. Future studies are needed to investigate correlations with the risk of organ complications, such as digital ulcers or pulmonary arterial hypertension.

Abstract
Systemic Sclerosis (SSc) is an autoimmune disease marked by dysregulation of the immune system, tissue fibrosis and dysfunction of the vasculature. Vascular damage, remodeling and inadequate endothelial repair are hallmarks of the disease. Since early stages of SSc, damage and apoptosis of endothelial cells (ECs) can lead to perivascular inflammation, oxidative stress and tissue hypoxia, resulting in multiple clinical manifestations. Raynaud's phenomenon, edematous puffy hands, digital ulcers, pulmonary artery hypertension, erectile dysfunction, scleroderma renal crisis and heart involvement severely affect quality of life and survival. Understanding pathogenic aspects and biomarkers that reflect endothelial damage in SSc is essential to guide therapeutic interventions. Treatment approaches described for SSc-associated vasculopathy include pharmacological options to improve blood flow and tissue perfusion and, more recently, cellular therapy to enhance endothelial repair, promote angiogenesis and heal injuries. This mini-review examines the current knowledge on cellular and molecular aspects of SSc vasculopathy, as well as established and developing therapeutic approaches for improving the vascular compartment.

Abstract
Systemic sclerosis (SSc) is an autoimmune disease, characterized by the presence of generalized vasculopathy and tissue fibrosis. Collagen vascular disorder in SSc is due to fibroblast and endothelial cell dysfunctions. This leads to collagen overproduction, vascular impairment and immune system abnormalities and, in the last stage, multi-organ damage. Thus, to avoid organ damage, which has a poor prognosis, all patients should be carefully evaluated and followed. This is particularly important in the initial disease phase, so as to facilitate early identification of any organ involvement and to allow for appropriate therapy. Pulmonary disease in SSc mainly involves interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH). High-resolution computed tomography (HRCT) and pulmonary function tests (PFT) have been proposed to monitor parenchymal damage. Although transthoracic echocardiography is the most commonly used screening tool for PAH in SSc patients, definitive diagnosis necessitates confirmation by right heart catheterization (RHC). Moreover, some studies have demonstrated that nailfold videocapillaroscopy (NVC) provides an accurate evaluation of the microvascular damage in SSc and is able to predict internal organ involvement, such as lung impairment. This review provides an overview of the correlation between lung damage and microvascular involvement in SSc patients.

Nailfold capillary changes in newly diagnosed hypertensive patients: An observational analytical study. Microvasc Res 2021; 136:104173.

Abstract
INTRODUCTION Nail Fold capillaroscopy (NFC) is used to evaluate microvascular changes in the horizontally lying capillaries in the proximal nail fold. Arterial hypertension affects the microvascular beds producing structural changes. Our objective was to evaluate qualitative and quantitative NFC changes in newly diagnosed hypertensives as compared to age and sex matched normotensive controls and to determine association, if any, with microvascular changes visualized on fundoscopy. MATERIALS AND METHODS This observational, analytical study involved 41 newly diagnosed hypertensives (18-60 years) with 41 normotensive age and sex matched normotensive controls. The mean capillary density (MCD) and morphological changes were assessed for all, while fundoscopy was done for study group participants. The collected data was statistically analyzed. RESULTS The MCD in newly diagnosed hypertensives (5.21 ± 0.90 capillaries/mm) was significantly lower than normotensive controls (6.50 ± 0.65 capillaries/mm) (p < 0.001) in our study. Qualitative morphologic changes were more common in hypertensive patients including meandering capillaries, capillary dilation, avascular areas, bushy capillaries, and microhemorrhages (p value <0.001). Capillary disarray (73.17%) was a unique morphologic change seen significantly more commonly in study group (p < 0.001). Among hypertensives, MCD was lesser in patients with retinopathy (p = 0.125) and with microalbuminuria, while avascular areas and dilated capillaries were significantly more common. CONCLUSION Our study supports the role of NFC with USB dermatoscope in detecting unique microvascular morphological alterations in hypertensives, which were more frequent as well as distinctive, as compared to healthy controls. A good correlation with fundoscopic features and microalbuminuria suggests that it could be useful in predicting/detecting cardiovascular, or renal complications early, with an advantage of easy accessibility and repeatability.

Abstract
BACKGROUND Systemic sclerosis is a rare autoimmune disease characterized by skin and organ fibrosis, and vasculopathy. Raynaud's phenomenon is almost universally present in systemic sclerosis and can be the most debilitating symptom. Raynaud's phenomenon may lead to the development of digital ulcers, potentially complicated by infection, tissue necrosis, and auto-amputation. Recommended treatments have variable efficacy. METHODS We report the case of a 30-year-old woman with diffuse systemic sclerosis suffering from severe Raynaud's phenomenon and digital ulcers with digital tissue necrosis who was treated with combination therapy of an endothelin receptor antagonist and phosphodiesterase 5 inhibitor. In addition, we reviewed the literature on the topic. RESULTS Previous therapy with calcium-channel blockers, intravenous iloprost, and bosentan had all failed to control symptoms. We added sildenafil in combination with bosentan and observed a rapid and sustained treatment effect. Raynaud's phenomenon severity, number of attacks, and attack duration decreased within 2 weeks of initiating treatment. Furthermore, this resulted in the healing of established digital ulcers. CONCLUSION Our case report suggests that combination therapy may be a feasible treatment for the most severely affected and refractory patients. In our literature review, we found one retrospective study and three additional cases with similarly encouraging results.

Abstract
Nailfold videocapillaroscopy (NVC) is an easy tool used for the assessment of patients with Raynaud's phenomenon (RP) as possibly associated with systemic sclerosis (SSc). Recent insights have also highlighted its role in the diagnostic assessment of idiopathic inflammatory myopathies (IIMs). The aim of this study is to describe the diagnostic role of NVC in a series of 361 consecutive patients with interstitial lung disease (ILD). All the patients were assessed by clinical pulmonary and rheumatic examinations, blood exams, high-resolution computed tomography and NVC. NVC was considered positive only in the presence of avascular areas or giant capillaries, but also, the presence of bushy capillaries (BCs) was recorded. NVC was positive in 17.7% of ILD patients and in 78.1% of ILD patients associated with a diagnosis of connective tissue disease (CTD). In 25% of SSc-ILD patients, NVC proved necessary for a correct diagnosis. The presence of BCs and/or NVC positivity in ILD patients with normal levels of creatine phosphokinase is associated with amyopathic IIM, regardless the presence of RP. In conclusion, NVC is useful for the diagnostic assessment of incomplete forms of CTD and in amyopathic IIMs. NVC should be considered in the diagnostic assessment of ILD patients regardless of the presence of RP.

Abstract
BACKGROUND Despite the great interest in capillaroscopy in systemic sclerosis (SSc), research on the possible combinations of different microvascular phenomena at different fingers in SSc patients have not been performed until now. OBJECTIVE To assess the diversity of capillaroscopic findings in SSc. METHODS The study includes analysis of the capillaroscopic findings in 40 SSc patients who were divided into the following categories: "scleroderma", type pattern - "early", "active", "late" phase, normal and/or nonspecific findings. The data were analyzed using descriptive statistics and t test. RESULTS In 77% of the patients, inhomogeneity of the capillaroscopic findings of the fingers was detected. The most frequent combinations of capillaroscopic patterns were "early + active" (n = 7), "active + late" phase (n = 7), "active" phase + normal and/or nonspecific findings (n = 6), "early + active" phase + normal and/or nonspecific findings (n = 4). Concomitant presence of normal and/or nonspecific findings and "late" phase was detected in only 3 cases. CONCLUSION Inhomogeneity of the capillaroscopic findings in SSc is a frequent phenomenon. The results indicate that combinations of "scleroderma" type capillaroscopic findings from different phases could be observed as well as concomitant appearance of pathological and normal/or nonspecific findings of different digits. This phenomenon could be a result of the complex action of different factors eg, disease duration, severity of Raynaud's phenomenon, presence of digital ulcers, local action of different angiogenic and angiostatic factors, gradual transition from one phase to another due to the extensive capillary area, therapeutic interventions.
