Rare Case of Limited Systemic Sclerosis with Left Ventricle Aneurysm.

Scleroderma is a rare connective tissue disorder with multisystem involvement with unknown and complex etiopathogenesis. Scleroderma is classified based on clinical and serological criteria and can be divided into two forms: localized scleroderma or systemic sclerosis, which can further be classified into limited systemic sclerosis or diffuse systemic sclerosis. There are few cases of aortic aneurysm and left ventricle aneurysm in systemic sclerosis but no such case in limited scleroderma in available literature. Here, we describe a rare case of limited systemic sclerosis with left ventricular aneurysm.

Impact and associates of digital pitting in patients with systemic sclerosis: a pilot study.

Objective: Despite being a cardinal clinical sign of systemic sclerosis (SSc), digital pitting has been little studied. Our objective was to test, in a pilot study, the hypothesis that pitting is painful and associated with digital vascular disease severity.Method: Fifty patients with SSc were recruited: 25 with and 25 without digital pitting. Fingertip pain was assessed on a 0-10 scale. Thermography of both hands assessed surface temperature, allowing calculation of the distal-dorsal difference (temperature gradient) for each finger. Nailfold capillaroscopy was performed in each finger using a dermatoscope, and graded on a 0-3 scale (0 = normal; 3 = grossly abnormal).Results: In the 25 patients with digital pitting, 65 fingers in total were affected (mainly the index and middle fingers). Pain scores were higher in 'pitting' patients [median 4 (interquartile range 3-8) vs 0 (0-2), p < 0.001], and pitting patients reported that pitting impacted on activities of everyday living. Temperature gradients along the fingers did not differ significantly between patients with and without pitting (p = 0.248). Pitting patients were more likely to have 'grossly abnormal' capillaries than those without pitting, and less likely to have 'no/mild' nailfold capillary changes.Conclusions: Digital pitting is painful and impacts on hand function. Capillaroscopy findings provide further support for an association between pitting and severity of digital vascular change. Larger, more comprehensive studies are required to examine the pathophysiology of pitting and to pave the way to therapeutic intervention, ideally including preventive strategies.

Colonic Manifestations and Complications Are Relatively Under-Reported in Systemic Sclerosis: A Systematic Review.

OBJECTIVES: Although systemic sclerosis (SSc) is known to affect the gastrointestinal (GI) tract, most of the literature focuses on esophageal, small intestinal, or anorectal manifestations. There have been no reviews focused on large bowel SSc complications in over 30 years. The aim of this study is to perform a systematic review of colonic manifestations and complications of SSc. METHODS: An experienced librarian conducted a search of databases, including English and Spanish articles. The search used keywords including "systemic sclerosis," "scleroderma," and "colon." A systematic review was performed using Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Case reports/series were screened for validity by adapting from criteria published elsewhere. RESULTS: Of 1,890 articles, 74 met selection criteria. Fifty-nine of the 77 articles were case reports/series. The most common article topics on colonic SSc complications were constipation/dysmotility (15), colonic volvulus (8), inflammatory bowel disease (7), microscopic colitis (6), megacolon (6), and telangiectasia (6). Colonic manifestations constituted 24% of articles on GI complications of SSc. There were a total of 85 cases (84% women, with a median age of onset of colon complication of 52 years). Limited cutaneous SSc phenotype (65.6%) was more common than diffuse (26.2%). Patients frequently had poor outcomes with high mortality related to colonic complications (27%). Recent studies explore contemporary topics such as the microbiome in SSc and prucalopride for chronic constipation in SSc. DISCUSSION: Colonic complications comprise a large proportion of the published reports on GI symptoms afflicting patients with SSc and require raised diagnostic suspicion and deliberate action to avoid potentially serious complications including death.

Prediction of organ involvement in systemic sclerosis by serum biomarkers and peripheral endothelial function.

OBJECTIVES: To identify prognostic factors among serum biomarkers and endothelial vasodilator function findings in patients with systemic sclerosis (SSc). METHODS: This is a clinical observational study. We assessed 60 consecutive SSc patients (44 limited cutaneous-type, 16 diffuse cutaneous-type). Circulating growth differentiation factor-15 (GDF-15), placenta growth factor (PlGF), endostatin, vascular endothelial growth factor (VEGF), and pentraxin 3 (PTX3) were measured by ELISA. Peripheral endothelial function was measured by forearm blood dilatation response to brachial artery occlusion using noninvasive plethysmography (EndoPAT2000), which is associated with nitric-oxide-dependent vasodilatation and yields a reactive hyperemia index (RHI). We evaluated whether abnormalities in these values were associated with type of SSc - namely, diffuse cutaneous SSc (dcSSc) or limited cutaneous SSc (lcSSc) - or organ involvement including interstitial lung disease (ILD), digital ulcer (DU) and estimated right ventricular systolic pressure (RVSP) by echocardiography >30 mmHg. RESULTS: SSc patients showed significantly elevated serum GDF-15, PlGF, endostatin and VEGF but not PTX3 compared with controls. GDF-15 and PlGF were high in dcSSc patients. EndoPAT-RHI was low, and incidence of RVSP >30 mmHg was high in dcSSc. Multivariate analysis revealed that elevated GDF-15 was highly predictive of dcSSc, ILD or RVSP >30 mmHg. PlGF for DU was also found. Conversely, a low EndoPAT-RHI value was predictive of the presence of dcSSc, ILD or DU. CONCLUSIONS: This is the first study to inclusively investigate the relationships among biomarkers, EndoPAT-RHI and organ involvement in patients with SSc. Our data suggest a complex pathological progression of SSc through fibrotic impairment and microvascular damage.

Gender differences in early systemic sclerosis patients: a report from the EULAR scleroderma trials and research group (EUSTAR) database.

OBJECTIVES: To describe differences in clinical presentation between men and women in a large group of patients with early (<3 years' duration) systemic sclerosis (SSc) according to disease subsets. METHODS: A cross-sectional analysis of the prospective EULAR Scleroderma Trial and Research database (EUSTAR) was performed. Patients fulfilling preliminary ACR 1980 classification criteria for SSc, with less than 3 years from the first non-Raynaud's symptom at first entry, were selected. A group of patients with less than 3 years from the first SSc symptom, including Raynaud's phenomenon, was also analysed. SSc related variables, including antibodies, SSc subsets, disease activity and organ involvement were included. Descriptive and bivariate analyses were performed. RESULTS: A total of 1,027 patients were included, 90% Caucasian, 80% women, and 40% with diffuse cutaneous disease. In early stages of SSc, men showed more frequently than women active disease, diffuse cutaneous subset, anti-Scl-70 antibodies, elevated acute phase reactants, muscular and pulmonary involvement. Differences between men and women were confirmed in the limited, but not in the diffuse SSc subset. The results were similar when 650 patients with less than three years from the first SSc symptom, including Raynaud's phenomenon, were analysed. CONCLUSIONS: In early stages of SSc, men present signs and symptoms of more severe disease. In the limited disease subset, men might appear with clinical features and organ involvement similar to those of the diffuse subgroup. In clinical practice, the identification of such differences might help to select the appropriate management for each particular patient.

High burden of skin sclerosis is associated with severe organ involvement in patients with systemic sclerosis and systemic sclerosis overlap syndrome.

The objective of this study is to investigate the impact of skin sclerosis burden on an internal organ involvement over a 1-year period, as measured by time-adjusted accrual-modified Rodnan skin score (TA-mRSS), and to evaluate association between TA-mRSS patterns and laboratory tests in patients with systemic sclerosis (SSc). This prospective study was conducted at Siriraj Hospital (Bangkok, Thailand) during the November 2013-November 2016. SSc patients by ACR/EULAR 2013 or ACR 1980 criteria were eligible. TA-mRSS was classified as low, intermediate, or high, and then compared between groups. Correlation between the arithmetic mean of laboratory tests and TA-mRSS was assessed by multiple linear regression analysis. A total of 118 patients, with 81.4% women, median (IQR) age 49.8 (43.8, 55.1) years, disease duration from onset of non-Raynaud symptoms to first visit of 3.3 (1, 6.8) years, 78% dcSSc, and 75.3% anti-Scl-70 positivity, were analyzed. TA-mRSS over 1 year ranged from 0 to 37.44. The high skin sclerosis burden group had a median TA-mRSS > 7.26 (> 67th percentile). Patients with high TA-mRSS were dcSSc, high initial and average mRSS, and had tendon friction rub, digital ischemic complications, usual interstitial pneumonia, diastolic dysfunction, gastrointestinal dysmotility, and low serum albumin. In multiple linear regression analysis, the arithmetic mean of hemoglobin (B = - 1.007, 95% CI - 1.779 to - 0.236), erythrocyte sedimentation rate (B = - 0.078, 95% CI - 0.126 to - 0.029), serum glutamic oxaloacetic transaminase (B = 0.073, 95% CI 0.026-0.12), creatine phosphokinase (B = 0.012, 95% CI 0.003-0.021), and albumin (B = - 4.117, 95% CI - 6.958 to - 1.276) were associated with TA-mRSS. This study found a higher cumulative course of mRSS over a 1-year period to be significantly associated with severe internal organ involvement.

Use of silver diamine fluoride for the maintenance of dental prostheses in a high caries-risk patient: A medical management approach.

A technique for using silver diamine fluoride (SDF) as part of a regimen to help maintain dental prostheses in a patient with scleroderma and at high risk of caries is presented. Medically compromised, xerostomic, or elderly patients generally face greater risk of caries and specifically with prosthetic retainer teeth. SDF is a minimally invasive solution to this problem. A technique is described for using SDF to arrest and prevent new caries with the goal of maintaining fixed and removable prostheses and supporting teeth in a cost-effective manner.

Increased proportions of functionally impaired regulatory T cell subsets in systemic sclerosis.

Treg abnormalities have been implicated in the pathogenesis of systemic sclerosis (SSc). Treg subpopulations and their cytokines, IL-10 and TGF-ß in the peripheral blood of early stage SSc patients were investigated. We hypothesized that epigenetically regulated methylation of the FOXP3 promoter and enhancer regions are altered in Tregs of SSc patients, which might be involved in the T cell imbalance. CD4+CD25+Foxp3+CD127- Treg cells were significantly elevated in patients with diffuse cutaneous SSc and in patients with anti-Scl-70/RNA-Pol-III autoantibody positivity and with lung fibrosis. Increased CD62L+ Treg cells were present in all SSc subgroups. The production of immunosuppressive cytokines by both CD127- and CD62L+ Tregs was diminished. We observed reduced methylation of Treg specific FOXP3 enhancer regions, and elevated FOXP3 gene expression in active SSc cases with negative correlation in the frequency of CD62L+IL-10+ Tregs. Our data indicate an inappropriate distribution and cytokine production of Treg cells in early form SSc.

The limited cutaneous form of systemic sclerosis is associated with urinary incontinence: an international multicentre study.

Objectives: The aim of this study was to explore the association between urinary incontinence (UI) and the main clinical and serological subsets of SSc, to assess risk factors for UI and its impact on quality of life (QoL). Methods: UI and QoL were assessed through self-administered questionnaires in 334 patients with SSc from five European tertiary centres. Logistic regressions were performed to test the association between clinical forms, serological status and UI and to adjust for confounders. Further independent predefined SSc risk factors for UI were tested through a multivariable logistic model. Results: The prevalence of UI was 63% (95% CI: 60, 68%). lcSSc and ACAs were both significantly associated with UI even after adjusting for age, sex, disability, diabetes, BMI, caffeine consumption, dyspnoea, faecal incontinence, abnormal bowel movement, presence of overlapping rheumatological disease and pulmonary hypertension [adjusted odds ratio (OR) = 2.4; 95% CI: 1.2, 4.7]. ACA and lcSSc doubled the risk of frequent and heavy urinary leaks. Factors independently associated with UI were as follows: lcSSc (OR = 2.2; 95% CI: 1.1, 3.2), ACA (OR = 2.8; 95% CI: 1.4, 5.8), female sex (OR = 10.8; 95% CI: 2.8, 41.3), worsening of dyspnoea (OR = 6.8; 95% CI: 1.2, 36.7), higher HAQ-DI (OR = 3.2; 95% CI: 1.5, 6.7), BMI (OR = 1.1; 95% CI: 1.0, 1.1) and active finger ulceration (OR = 0.3; 95% CI: 0.1, 0.7). Patients suffering from UI had decreased QoL. Conclusion: Self-reported UI is frequent in SSc and disproportionally affects the limited cutaneous form of the disease and patients positive for ACA.

Comparison of change in end tidal carbon dioxide after three minutes of step exercise between systemic sclerosis patients with and without pulmonary hypertension.

OBJECTIVES: Pulmonary hypertension (PH) is an important cause of morbidity and mortality in patients with SSc. The submaximal heart and pulmonary evaluation (step test) is a non-invasive, submaximal stress test that could be used to identify SSc patients with PH. Our aims were to determine whether change in end tidal carbon dioxide ([Formula: see text]) from rest to end-exercise, and the minute ventilation to carbon dioxide production ratio ([Formula: see text]), both as measured by the step test, differ between SSc patients with and without PH. We also examined differences in validated self-report questionnaires and potential PH biomarkers between SSc patients with and without PH. METHODS: We performed a cross-sectional study of 27 patients with limited or dcSSc who underwent a right heart catheterization within 24 months prior to study entry. The study visit consisted of questionnaire completion; history; physical examination; step test performance; and phlebotomy. [Formula: see text], [Formula: see text], self-report data and biomarkers were compared between patients with and without PH. RESULTS: SSc patients with PH had a statistically significantly lower median (interquartile range) [Formula: see text] than SSc patients without PH [-2.1 (-5.1 to 0.7) vs 1.2 (-0.7 to 5.4) mmHg, P = 0.035], and a statistically significantly higher median (interquartile range) [Formula: see text] [53.4 (39-64.1) vs 36.4 (31.9-41.1), P = 0.035]. There were no statistically significant differences in self-report data or biomarkers between groups. CONCLUSION: [Formula: see text] and [Formula: see text] as measured by the step test are statistically significantly different between SSc patients with and without PH. [Formula: see text] and [Formula: see text] may be useful screening tools for PH in the SSc population.

Silent myocarditis in systemic sclerosis detected by cardiovascular magnetic resonance using Lake Louise criteria.

BACKGROUND: Systemic sclerosis (SSc) is an autoimmune disease characterized by microvascular abnormalities, inflammation and fibrosis. We hypothesized that myocarditis may be diagnosed in asymptomatic SSc, undergoing routine cardio-vascular magnetic resonance (CMR) for fibrosis assessment, using the Lake Louise criteria: T2 ratio, early (EGE) and late gadolinium enhanced (LGE) images. METHODS: Eighty-two asymptomatic SSc, diagnosed according to American College of Rheumatology criteria, aged 43 ± 5 yrs., 62 with diffuse (dSSc) and 20 with localized (lSSc) systemic sclerosis were evaluated by CMR, performed at 1.5 T scanner, according to Lake Louise criteria. RESULTS: CMR documented normal biventricular function in all SSc. However, 7/62 (11.2%) with dSSc and 2/20 (10%) with lSSc, had CMR signs of myocarditis according to Lake Louise criteria, without any clinical cardiac symptom. In these 9 patients, T2 ratio, EGE ratio and LGE (positive in all 9 SSc) were 2.8 ± 0.5%, 8 ± 3% and 5 ± 3% of LV mass, respectively. No correlation between CMR and blood inflammatory indices (C-reactive protein and erythrocyte sedimentation rate), cardiac troponin T, disease characteristics or type of SSc was identified. A repeat CMR at 6 months, after treatment with prednisone and azathioprine, showed normalisation of the acute inflammation CMR indices. CONCLUSIONS: Silent myocarditis may be diagnosed using the Lake Louise paper criteria in SSc patients without cardiac symptoms, has no correlation with blood inflammatory indices, cardiac troponin or disease characteristics. CMR is a promising tool to diagnose silent myocarditis in SSc and monitor the response to immunosuppressive treatment.

Digital ulcers score: a scoring system to assess digital ulcers in patients suffering from systemic sclerosis.

OBJECTIVES: To develop a standardized scoring system to assess the severity of DUs in SSc patients and correlate it with functional outcomes. METHODS: In this cross-sectional, longitudinal study in SSc patients with DUs (n=65) we developed a digital ulcers score (DUS) for the assessment of DUs. DUS and the ABILHAND score were measured at each visit and differences were analysed using Tamhane's T2 test. Spearman's Rho test was applied for correlational analysis of DUS and functional outcomes. We calculated a linear regression model using clustered standard errors for correlation analysis between DUS and ABILHAND over time. RESULTS: 117 assessments of DUS were performed in 65 SSc patients. Mean DUS was 11.6±1.9 (range: 0-68). Subgroup analyses showed a higher DUS in patients suffering from diffuse cutaneous SSc when compared to patients with limited cutaneous SSc (12.8±3.0 vs. 9.7±2.2 p=0.18). There was no correlation between the DUS and manual ability using the ABILHAND score (overall: n=106 r=-0.138, p=0.22). We observed a small but significant linear correlation between the DUS and the ABILHAND score for a single patient over time (n=14, R2=0.31, r=0.06, p=0.02). CONCLUSIONS: The DUS is a feasible scoring instrument to assess severity of DUs in SSc patients. In accordance with the literature the severity of DUs correlates with clinical parameters but also severity of the disease. Further study is needed to establish the DUS as a standardized tool for the assessment of DUs.

Fibrillary glomerulonephritis associated with limited scleroderma: a case report.

Fibrillary glomerulonephritis (GN) is a rare glomerular disorder that has been associated with monoclonal gammopathies, malignancies, chronic infections, and autoimmune disorders. We present the case of a 56-year-old woman with limited-type scleroderma and remote discoid lupus, evaluated for dipstick positive hematuria and preserved kidney function. Serologies were negative. Kidney biopsy revealed fibrillary GN. Her renal function and proteinuria remain stable 4 years after her initial diagnosis. This case is unusual both in its presentation and evolution, but mostly because it is the first reported case of fibrillary GN in association with limited type scleroderma.

Assessment of myocardial fibrosis and microvascular damage in systemic sclerosis by magnetic resonance imaging and coronary angiotomography.

OBJECTIVE: Cardiac involvement in SSc is characterized by myocardial fibrosis, arrhythmias and pericarditis. Prevalence studies have shown variable results. The objective of this study was to determine the prevalence of cardiac involvement in SSc patients using the non-invasive, highly sensitive diagnostic methods of cardiac MRI and coronary angiotomography. METHODS: We included 62 SSc patients and excluded those with heart disease prior to the onset of SSc, renal failure, diabetes mellitus, hyperlipidaemia, arterial hypertension, untreated thyroid disease, cor pulmonale, pregnancy or contraindications to performing cardiac MRI. All underwent clinical and laboratory evaluation, ECG, coronary angiotomography and cardiac MRI. RESULTS: The prevalence of myocardial fibrosis was 45% and was higher in dcSSc (59%) than in lcSSc patients (33%; P = 0.04). The mean left ventricular ejection fraction (LVEF) was lower in patients with myocardial fibrosis (56%) than in those without fibrosis (63%; P = 0.0009); myocardial fibrosis on MRI was more frequent in the basal-septal segments of the LV. Seventy-nine per cent of patients had subendocardial perfusion defects and these were associated with higher ultrasensitive serum CRP values. There was no association of myocardial fibrosis or microvascular damage with atherosclerosis. CONCLUSION: The prevalence of myocardial fibrosis on MRI attributable to SSc is 45%, is more frequent and severe in dcSSc patients, is associated with lower LVEF and affects mainly basal LV walls. Microvascular damage in SSc is common and is associated with elevated ultrasensitive CRP levels. Cardiac damage due to SSc is not associated with coronary artery disease.

Sclerodermoid lesions in a patient with multiple transplants and porphyria cutanea tarda.

Patients with chronic graft versus host disease may exhibit a range of sclerotic features. Herein we present a patient with confirmed porphyria cutanea tarda who subsequently developed chronic graft versus host disease.

Sex and time to diagnosis in systemic sclerosis: an updated analysis of 1,129 patients from the Canadian scleroderma research group registry.

OBJECTIVES: A previous study found that time to diagnosis was significantly longer from onset of Raynaud's phenomenon for women compared to men with diffuse systemic sclerosis (SSc) and that, in limited SSc, it was more than twice as long for women than men. That study was limited, however, by the small number of men in disease subtype subgroups. The objective of the present study was to investigate the association of sex with time to diagnosis of SSc using a substantially larger patient sample. METHODS: Association between sex and time to diagnosis was assessed overall and stratified based on diffuse versus limited disease using Kaplan-Meier curves and Cox proportional hazards models. RESULTS: There were 1,129 patients in the study (median age=56.0 years; 978 [86.6%] women). Time to diagnosis was significantly longer for women (median=1.1 years) than men (median 0.8= years; p=0.037) with diffuse SSc following onset of Raynaud's phenomenon. There were no significant or substantive sex differences in time to diagnosis after Raynaud's onset in limited SSc or from onset of first non-Raynaud's disease manifestation in diffuse or limited SSc. CONCLUSIONS: Time to diagnosis was significantly longer for women compared to men with diffuse SSc following onset of Raynaud's phenomenon, but the difference was small and unlikely to be clinically significant. There were no differences in time to diagnosis following Raynaud's onset in limited disease or following onset of first non-Raynaud's disease manifestation in diffuse or limited disease. Overall, sex does not appear to influence time to diagnosis meaningfully.
