Abstract
Systemic sclerosis (SSc) is a chronic multisystemic disease characterized by immunological activation, diffuse vasculopathy, and generalized fibrosis exhibiting a variety of symptoms. A recognized precursor of SSc is Raynaud's phenomenon, which is part of the very early disease of systemic sclerosis (VEDOSS) in combination with nailfold videocapillaroscopy (NVC) impairment. The pathophysiology of ocular involvement, alterations in internal organs, and body integumentary system involvement in SSc patients are complicated and poorly understood, with multiple mechanisms presumptively working together. The most prevalent ocular symptoms of SSc are abnormalities of the eyelids and conjunctiva as well as dry eye syndrome, due to fibroblasts' dysfunction and inflammation of the ocular surface. In particular, lagophthalmos, blepharophimosis limitation of eyelid motion, eyelid telangiectasia, and rigidity or tightening of the lids may affect up to two-third of the patients. In addition, reduction in central corneal thickness, iris defects and higher rates of glaucoma were reported. In the first reports based on retinography or fluorescein angiography, about 50% of SSc patients showed signs of vascular disease: peripheral artery occlusion, thinning of retinal pigment epithelium and choroidal capillaries, ischemic areas surrounded by intraretinal extravasation and microaneurysms, and peripheral capillary non-perfusion. Successively, thanks to the advent of optical coherence tomography angiography (OCTA), several studies highlighted significant impairment of either the choriocapillaris and retinal vascular plexuses, also correlating with NVC involvement and skin disease, even in VEDOSS disease. Given the sensitivity of this technique, ocular micro-vasculopathy may act as a tool for early SSc identification and discriminate between disease stages.

Serum IL-17 and TNFα as prognostic biomarkers in systemic sclerosis patients: a prospective study. Rheumatol Int 2024; 44:119-128. [PMID: 38051374 PMCID: PMC10766799 DOI: 10.1007/s00296-023-05499-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Accepted: 10/24/2023] [Indexed: 12/07/2023]
Abstract
Recent reports have demonstrated that endothelial injury is critical in the pathogenesis of systemic sclerosis (SSc) and is associated with increased levels of circulating inflammatory biomarkers. This study aims to analyze the serum concentrations of selected cytokines and evaluate their relationship with SSc clinics and the long-term course of the disease. This study included 43 SSc patients and 24 matched healthy controls. In both groups, we measured serum levels of inflammatory cytokines related to the inflammatory response, such as tumor necrosis factor (TNF)α, interferon (IFN)γ, interleukin (IL)-4, IL-6, IL-10, and IL-17, and fibroblast activation protein (FAP). Additionally, in SSc patients, we evaluated the presence of four single nucleotide polymorphisms (SNPs) located in the promotor region of the TNFA gene, namely rs361525, rs1800629, rs1799964, and rs1799724, which might be related to increased TNFα concentrations. The main aim consisted of associating inflammatory cytokines with (1) clinical disease characteristics and (2) longitudinal observation of survival and cancer prevalence. SSc patients were characterized by a 17% increase in serum TNFα. There was no other difference in serum cytokines between the studied groups and diffuse vs. limited SSc patients. As expected, evaluated serum cytokines correlated with inflammatory biomarkers (e.g., IL-6 and C-reactive protein). Interestingly, patients with higher IL-17 had decreased left ventricle ejection fraction. During the median 5-year follow-up, we recorded four cases of neoplastic diseases (lung cancer in two cases, squamous cell carcinoma of unknown origin, and breast cancer with concomitant multiple myeloma) and nine deaths. The causes of death included lung cancer (n = 2), renal crisis (n = 1), multiple-organ failure (n = 1), and unknown reasons in five cases. Surprisingly, higher TNFα was associated with an increased cancer prevalence, while elevated IL-17 with death risk in the follow-up. Furthermore, the AG rs361525 genotype referred to higher TNFα levels than GG carriers. Both AG rs361525 and CT rs1799964 genotypes were associated with increased cancer risk. Higher serum concentrations of TNFα characterize the SSc patients, with the highest values associated with cancer. On the other hand, increased IL-17 in peripheral blood might predict poor SSc prognosis. Further research is needed to validate these findings.

Abstract
To investigate the correlations between finger microvascular morphology and function in patients with systemic sclerosis (SSc) and the status of ocular microcirculation, as detected by nailfold videocapillaroscopy (NVC), laser speckle contrast analysis (LASCA), and optical coherence tomography angiography (OCTA). The enrollment included 32 SSc patients, classified according to the 2013 ACR/EULAR criteria, and 27 sex- and age-matched healthy controls. The participants underwent comprehensive rheumatological and ophthalmological examinations, as well as NVC, LASCA, and OCTA analysis on the same day at a single center from March to October 2022. SSc patients receiving intravenous prostanoids cycles were assessed at least 1 month after infusion. Statistical analysis was conducted using Stata® 15.1. Significant direct correlations were observed between the mean capillary number (at NVC) and the mean perfusion of fingers (at LASCA) with the retinal and choroidal perfusion (at OCTA) (all p < 0.05). In addition, a significantly reduced retinal and choroidal perfusion was detected in SSc patients vs controls (all p < 0.05). Interestingly, diffuse cutaneous SSc (dcSSc) patients exhibited a lower choroidal perfusion (p = 0.03) but an increased choroidal thickness (CT) than limited cutaneous SSc patients (p < 0.001). CT was increased also in patients with positive Scl70 antibodies and with a history of digital ulcers directly correlating with disease duration (r = 0.67, p = 0.001). Finally, the combination of LASCA and OCTA parameters showed a significant discrimination capacity between SSc patients and controls, with an area under the curve of 0.80 [95% CI (0.74, 0.87)]. Peripheral microvascular damage is correlated with impaired ocular microcirculation in SSc. The increased choroidal thickness observed in dcSSc may be related to local sub-endothelial extracellular matrix deposition. The combined analysis of choroidal and fingertip perfusion offers preliminary insights that may complement traditional diagnostic methods for SSc.

Abstract
PURPOSE OF REVIEW To describe the clinical significance of and the diagnostic approach to Raynaud phenomenon (RP) in the peripheral extremities and the heart. RECENT FINDINGS Nailfold capillaroscopy has recently been standardized in an expert consensus paper. Abnormal capillaroscopy in combination with specific autoantibody profiles and clinical signs are highly predictive of progression of RP to systemic sclerosis (SSc). Magnetic resonance imaging (MRI) can also perform tissue characterization of both the extremities and the heart. Microvascular wall abnormalities detected using nailfold capillaroscopy in patients with SSc may lead to deposition of erythrocyte-derived iron, due to microhemorrhages, which may predispose to fibrosis. MRI can assess the presence of iron using T2∗ measurements. SUMMARY RP is a hallmark of the microvasculopathy in SSc and can affect both the peripheral extremities and the heart. Nailfold capillaroscopy is the current gold standard for the evaluation of the peripheral microvasculature. Other imaging modalities include thermography, laser Doppler-derived methods, 99m Tc-pertechnetate hand perfusion scintigraphy, power Doppler ultrasonography, dynamic optical coherence tomography, MRI, and photoacoustic imaging, but these are currently not widely used. Cardiac RP can be investigated with positron emission tomography or cardiovascular magnetic resonance, with the latter offering the additional possibility of tissue characterization and iron content quantification secondary to microhemorrhages.

Abstract
In this study, we aim to investigate retinal thickness (RT) and superficial vascular density (SVD) differences between patients with systemic sclerosis (SSc) and healthy controls (HCs) by optical coherence tomography angiography (OCTA). Sixteen patients with a definitive SSc diagnosis without clinical signs of retinopathy and 16 normal control subjects were recruited. All individuals underwent OCTA scanning to assess macular RT and SVD. We divided each image into nine subregions as the early treatment diabetic retinopathy study (ETDRS). Visual acuity (VA) was considerably different between patients with SSc (32 eyes) and control subjects (32 eyes) (p < 0.001). Compared to the control group, individuals with SSc had decreased inner RT in inner superior, outer superior, outer temporal, inner temporal, center, and inner nasal regions (p < 0.05). Outer RT was decreased in the outer and inner temporal regions, and full RT was decreased in the regions of outer superior, inner superior, inner temporal, and outer temporal, in comparison to the control group (p < 0.05). Patients with SSc had significant reduction of SVD in the inner and outer of both superior and temporal, besides outer nasal regions than controls. (p < 0.05). Moreover, SVD was significantly associated with the outer temporal region of patients suffering from SSc (p < 0.05). Diagnostic Sensitivity of RT and SVD of Inner Superior Regions in SSc, as indicated by areas under curves of the Receiver Operating Characteristic (ROC), were 0.874 (95% CI: 0.786-0.962) and 0.827 (95% CI: 0.704-0.950), respectively. In conclusion, VA may be affected by RT variations inside the macula in patients with SSc. Measuring RT with OCTA could be a useful predictor of early diagnosis.

Abstract
PURPOSE To analyze the macular microvascular (MMV) architecture, radial peripapillary capillary (RPC) network and choriocapillaris using optical coherence tomography angiography (OCT-A) in patients with systemic sclerosis (SSc) without systemic comorbidities. METHODS The vessel densities (VDs) of the MMV, foveal avascular zone (FAZ) parameters, choriocapillaris flow areas (CCFAs), RPC VDs, and optic nerve head (ONH) parameters were measured by OCT-A. Retinal thickness and subfoveal choroidal thickness (SFCT) were measured by spectral-domain optical coherence tomography (SD-OCT). The SD-OCT and OCT-A measurements of 53 eyes of 30 SSc patients were compared with 61 eyes of 33 healthy controls. RESULTS In the MMV analysis, a decrease in the VDs of the superficial capillary plexus and an increase in the FAZ area, FAZ perimeter and non-flow area were detected in the SSc group compared to the controls (P=0.007, P=0.001, P=0.029, P=0.018, and P=0.039, respectively). While there was a decrease in SFCT, no change was found in CCFA (P=0.001 and P=0.902, respectively). The RPC analysis revealed a decrease in the VDs of all vessels for the entire area and the intradisc area, as well as the VDs of the small vessels for the intradisc area (P=0.021, P=0.001, and P=0.003, respectively). In the ONH analysis, there was an increase in the C/D area ratios and cup volumes, and a decrease in the rim areas and nasal quadrant retinal nerve fiber layer thickness (P=0.004, P=0.004, P=0.013, and P=0.032, respectively). CONCLUSION Decreases in RPC and MMV VDs and changes in ONH parameters were found in OCT-A measurements in patients with SSc.

Abstract
BACKGROUND AND AIMS Adverse changes to the microcirculation play an important role in the pathogenesis of cardiovascular disease (CVD), and inflammation is a key causal mechanism. We investigated the relationship between inflammatory markers and retinal microvascular parameters. METHODS Studies up to April 2021 were identified in Medline, Embase and PubMed with the following terms: retinal microvascular parameters, inflammatory markers, and observational studies. Correlation coefficients of inflammatory markers and retinal vascular caliber were pooled using the random-effects model. RESULTS Of 4783 studies identified, 36 met the inclusion criteria (general population 26, patients with diseases 10). C-reactive protein (CRP) and white blood cell count (WBC) were most frequently reported. We conducted meta-analysis with 12 CRP studies (22422 participants) and six WBC studies (15209 participants), and also performed a narrative review of all studies. There was consistent evidence of a modest association between CRP and venular caliber (r = 0.09, 95%CI 0.05 to 0.12), but little evidence of an association between CRP with retinal arteriolar caliber (r = 0.00, 95%CI -0.02 to 0.02). Similarly, WBC had stronger associations with venular (r = 0.18, 95%CI 0.05 to 0.31) than arteriolar caliber (r = 0.05, 95%CI 0.01 to 0.09). Narrative review of other inflammatory markers showed consistent findings. There was little evidence of associations between inflammation markers and other microvascular parameters, fractal dimension and tortuosity. CONCLUSIONS There was more evidence for an association of inflammation with retinal venular than with arterial caliber. The findings suggest a potential druggable mechanism contributing to microvascular damage that has been relatively overlooked in CVD pathogenesis and treatment.

[PMID: 33845106 DOI: 10.1016/j.mvr.2021.104166] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 03/30/2021] [Accepted: 03/30/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVE Ocular involvement in systemic sclerosis (SSc) has been documented; however it cannot be distinguished from secondary changes due to concomitant hypertension.Therefore, the aim of this prospective cross-sectional study was to demonstrate the direct effects of Ssc on retinal and choroidal microvasculature in patients without hypertension. METHODS 47 SSc patients and 44 age- and sex-matched healthy control subjects were enrolled in this study. In fundus examination: Increased vascular tortitis, focal or general arteriolar narrowing, arteriovenous notch, severe exudation, microhemorrhage, and pigment epithelial changes in the retina of SSc patients without hypertension were investigated. Patients with at least two of the above findings were considered to have retinopathy After that, patients were divided into two groups according to the presence of retinopathy in this study. Retinal and choroidal microvasculature were evaluated using optical coherence tomography angiography. RESULTS There was a significant decrease in SSc patients with retinopathy in both superficial capillary plexus vessel density (SCP VD) and deep capillary plexus vessel density (DCP VD) compared to the control group. Full avascular zone (FAZ) evaluation tool variables (FAZ area, FAZ perimeter, foveal density) were significantly lower in all Ssc patients than in the healthy control group. It was found that the flow in the 1 mm and 3 mm circular area (Outer Retina 1-3 mm Flow Area) increased significantly in Ssc patients with retinopathy. Choroidal flow (Choriocapillaries 1 mm Flow Area) was statistically lower in Ssc patients with retinopathy. CONCLUSIONS We have showed an increase in the outer retina 1-3 mm flow area (circular area of the outer retina fold covering the fovea) despite the decrease in vascular density and choroidal thickness in scleroderma patients with retinopathy. Hence, we first demonstrated that Ssc itself may have an effect on retinal and choroidal microvasculature, independent of hypertension.

Prevalence of retinal changes in patients with systemic sclerosis: the association between retinal vascular changes and nailfold capillaroscopic findings. Reumatologia 2021; 59:27-34. [PMID: 33707793 PMCID: PMC7944954 DOI: 10.5114/reum.2021.103436] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Accepted: 01/16/2021] [Indexed: 11/20/2022] Open
Abstract
Background Systemic sclerosis (SSc) is a connective tissue disease affecting the skin and multiple organs. Most of the evidence on ocular involvement comes from small studies. We evaluated the retinal vascular changes in patients with SSc and its associations with types, disease duration, skin score, and nailfold capillaroscopy changes. Material and methods We evaluated the demographic, clinical and nailfold capillaroscopy data of 52 patients referring to the clinic of scleroderma with SSc according to the 2013 ACR/EULAR SSc criteria. In addition, full ophthalmic examination in 52 patients and fundus photography in 40 patients were done in the ophthalmology clinic. Results There were 52 (49 women and 3 men, 17 diffuse and 35 limited) patients with SSc with mean disease duration of 8 ±5 years and mean age of 40 ±9 years. Retinal changes in the ophthalmologic examination were seen in 30.7% as increased vascular tortuosity. None of the patients had cotton wool spot, hemorrhage or hard exudate. Forty patients underwent fundus photography and 22.5% of them had vascular tortuosity. Only the presence of hemorrhage in the nailfolds was correlated with retinal tortuosity, and the other characteristics of nailfold capillaroscopy did not have any association with retinal changes. Conclusions Retinal vascular changes were seen in about one third of our patients. There was no correlation between nailfold capillaroscopy, disease duration, type and skin score of SSc patients and retinal vascular changes. These findings suggest that the mechanisms or the quality of changes in the retinal vessels and nailfold vasculature may be different.

Correlation of retinal and choroidal microvascular impairment in systemic sclerosis. Orphanet J Rare Dis 2021; 16:27. [PMID: 33441156 PMCID: PMC7807887 DOI: 10.1186/s13023-020-01649-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Accepted: 12/17/2020] [Indexed: 11/24/2022] Open
Abstract
Purpose To investigate the correlation between retinal and choroidal microperfusion in patients with systemic sclerosis (SSc) using optical coherence tomography angiography (OCTA). Methods In this cross-sectional study SSc patients without clinical evidence of ocular involvement and healthy, age- and sex-matched volunteers were recruited. Participants underwent specific rheumatological and ophthalmological examinations, including optical coherence tomography (OCT) and OCTA. Retinal and choroidal thicknesses as well as perfusion of the retina and the choroidal sublayers were evaluated. Results A total of 15 SSc patients (30 eyes) with a median disease duration of 60 months and 15 matched, healthy controls (30 eyes) were recruited. OCT data revealed a significantly lower macular volume, as well as Sattler’s layer and Haller’s layer thickness in SSc patients compared to controls. In OCTA analysis, the perfusion of both retinal plexus as well as Sattler’s and Haller’s layer were significantly reduced in the SSc group. Patients with a disease duration of more than 60 months showed a statistically significant positive correlation between retinal and choroidal malperfusion, while those with a shorter disease duration did not. Conclusion OCTA analysis confirmed impairment of retinal and choroidal microperfusion in SSc patients, supporting the hypothesis of wide spreading vascular injury. In early stages, either the retinal or the choroidal perfusion seems to be involved, while later on, vascular impairment affects both tissues alike. Both, retinal and choroidal examinations should be considered as soon as the diagnosis of SSc is made, to avoid missing out on early alterations.

Abstract
Systemic sclerosis (SSc) is a rare, chronic autoimmune disease with unknown etiology. Its prominent features are fibrosis, vasculopathy and impaired immune response. Disease can also affect eyes leading to various findings in ophthalmological examination. The objective of this study was to determine the prevalence and type of ocular involvement in patients with SSc. A systematic literature review was conducted using electronic databases. A combination of following keywords was used: “systemic sclerosis” and ophthalmology-related search terms, including the keywords “eye”, “ocular” and “ophthalmic”. In conclusion, eyelid and conjunctival abnormalities and dry eye disease are among the most common ocular manifestations of SSc. Their diversity is connected to complexity of the disease.

The Role of Angiogenesis Factors in the Formation of Vascular Changes in Scleroderma by Assessment of the Concentrations of VEGF and sVEGFR2 in Blood Serum and Tear Fluid. Mediators Inflamm 2020; 2020:7649480. [PMID: 32410862 PMCID: PMC7204106 DOI: 10.1155/2020/7649480] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2019] [Revised: 11/10/2019] [Accepted: 12/30/2019] [Indexed: 11/18/2022] Open
Abstract
Systemic sclerosis (SSc) is a connective tissue disorder characterized by tissue hypoxia, excessive fibrosis of skin and internal organs, and angiogenesis imbalance. The aim of the study was to evaluate in SSc patients the association between the retinal microcirculation disturbances and the presence of peripheral trophic changes and to determine the role of angiogenesis factors in the formation of vascular changes in scleroderma. Twenty-five SSc patients and 25 age- and sex-matched healthy controls were included to the study. Assay of vascular endothelial growth factor (VEGF) and soluble VEGF receptor-2 (sVEGFR-2) in blood serum and tears was done for all patients and controls using enzyme-linked immunosorbent assay. Retinal blood circulation was investigated with fluorescein angiography (FA) in the SSc patients only. In our research, proportion of mainly hypertensive patients presenting with a large spectrum of retinal microvascular lesions was 72%, while proportion of patients with skin microvascular lesions within distal phalanxes of fingers and toes was 76%. We noticed that patients with pathological changes in the FA examination had finger ulcerations significantly more often than patients without changes in the eye fundus. There were no statistically significant differences in the serum concentration of VEGF and sVEGFR2 between subjects in both analyzed groups. Analysis of lower levels of VEGF (p = <0.001) and sVEGFR-2 (p = <0.001) in blood serum accompanied by simultaneous higher levels of VEGF/sVEGFR-2 ratio in tears of SSc patients, as compared with the control group, indicates the superiority of proangiogenic factors in patients' tears.

Abstract
OBJECTIVES Systemic sclerosis (SSc) is a rare and complex autoimmune disorder characterized by microvascular damage and progressive fibrosis which affects the skin and multiple other organs. Much of the published data concerning SSc and the eye consists of single case reports or small case studies. This systematic review aims to provide an overview of the current level of evidence for SSc-related ocular changes. MATERIALS AND METHODS A systematic literature review was conducted using 3 electronic databases, according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. A combination of following keywords was used: "Systemic Sclerosis" and ophthalmology-related search terms, including the keywords "Eye", "Ocular" and "Ophthalmic". All articles were screened by 2 independent reviewers at title, abstract and full text level. We solely included case-control studies that investigated specific ocular findings in SSc patients compared to healthy controls. RESULTS Nine of 270 articles were retained. Dry eye symptoms are associated with SSc, whereas objective signs (Schirmer I testing) show conflicting results. There is insufficient evidence of SSc-related changes to the central corneal thickness. In terms of posterior segment involvement, choroidal vasculature appears to be affected to greater extent than the retinal microcirculation. However, the limited number of patients included in the studies renders it hazardous to draw overall conclusions. CONCLUSIONS There is a paucity of well-designed case-control studies investigating possible ocular involvement in SSc. Our systematic review demonstrates limited proven associations between SSc and ocular abnormalities, mainly in terms of dry eye symptoms and choroidal thickness. Future standardized prospective studies are needed to clarify the impact of the disease on the eye.

Abstract
OBJECTIVE Quantification of retinal vessel morphology has emerged as a marker of cardiovascular health. We examined retinal microvascular diameters in RA, particularly in regard to systemic inflammation, subclinical atherosclerosis, and cardiovascular risk. METHODS Retinal images from RA patients and controls were processed using computerized software, to obtain CRAE and CRVE and AVR. Subclinical atherosclerosis was assessed with cIMT, and 10-year risk of general cardiovascular disease was calculated. RESULTS Both CRAE (78.8 ± 8.9 vs 90.2 ± 9.9 μm, P < .001) and AVR (0.69 ± 0.09 vs 0.81 ± 0.09, P < .001) were decreased in RA patients (n = 87) compared to controls (n = 46), whereas CRVE did not differ. Among RA patients, CRAE and AVR were inversely associated with both cIMT and CRP, whereas CRVE positively correlated with CRP (P < .05 for all). CRAE additionally correlated with cardiovascular risk score (r = -.396, P = .001). In the multivariate analysis, cardiovascular risk was associated with CRAE; age with CRVE, while CRP independently predicted AVR. CONCLUSIONS Our study shows altered retinal microvascular morphology in RA patients. Inflammation appears as the biological link for the observed association between retinal microvascular abnormalities and subclinical atherosclerosis. Retinal arteriolar narrowing might play its own role in cardiovascular risk prediction in RA.
