Objective: The aim of this study is to examine validity, reliability, and responsiveness to change of Patient-Reported Outcomes Measurement Information System Self-Efficacy for Managing Chronic Conditions in persons with systemic sclerosis.

Methods: We conducted a post hoc analysis of the Patient-Reported Outcomes Measurement Information System Self-Efficacy measure and other quality-of-life measures from systemic sclerosis participants from a 16-week randomized control trial. The trial compared an Internet-based self-management program to a control condition where participants were provided an educational book. All participants completed outcome measures at baseline and following the 16-week trial period.

Results: The mean age of participants was 53.7 years, 91% were female and systemic sclerosis subtype included 44.9% limited/sine and 43.1% diffuse; mean disease duration was 9.0 years. All self-efficacy subscales (Managing Emotions, Symptoms, Daily Activities, Social Interactions, and Medications/Treatment) demonstrated good internal consistency (.92-.96). All subscales showed statistically significant correlations with other validated measures of depressive symptoms and quality of life (.20-.86) but were not associated with satisfaction nor with appearance. The subscales appropriately discriminated between those with and without depressive symptoms and demonstrated responsiveness to change over the 16-week period for those who had a corresponding increase in reported quality of life.

Conclusion: The Patient-Reported Outcomes Measurement Information System Self-Efficacy measure is valid, reliable, and responsive to change for persons with systemic sclerosis.

Objective: Certain Hispanic/Latino (Hispanic) populations have been reported to have higher rates and severity of systemic sclerosis; however, little is known of systemic sclerosis in the American Southwest. This study compared manifestations of systemic sclerosis in Hispanics with non-Hispanics of New Mexico.

Methods: This cross-sectional longitudinal study included 109 systemic sclerosis patients followed over a mean of 12.6 ± 8.9 years. Subjects were repetitively evaluated including physical examination, echocardiography, chest imaging, and serologic testing and observed for complications. Disease characteristics and long-term outcomes were statistically compared between self-identified Hispanic and non-Hispanic subjects.

Results: A total of 73 (67%) systemic sclerosis subjects were Hispanic and 36 (33%) were non-Hispanic. The cohorts were similar in mean age, age of systemic sclerosis onset, limited versus diffuse cutaneous systemic sclerosis, telangiectases, gastroesophageal reflux disease, Raynaud's phenomenon, autoantibody profile, interstitial lung disease, pulmonary hypertension, scleroderma renal crisis, mortality, and comorbid malignancy (all p > 0.05). However, the standardized mortality ratio was increased in both cohorts relative to age-adjusted mortality: Hispanic: 2.08, confidence interval (1.94-2.24); non-Hispanic: 1.56, confidence interval (1.46-1.68). Furthermore, the standardized incidence ratio for malignancy was increased in both cohorts: Hispanic: 1.45, confidence interval (1.35-1.56); non-Hispanic: 1.24, confidence interval (1.16-1.34). The mean age of cancer diagnosis occurred at a significantly younger age in Hispanics (Hispanics: 53.1 ± 9.7 years; non-Hispanics 63.7 ± 7.9 years; 95% confidence interval: -19 ⩽ 10.6 ⩽ 2.2; p = 0.016).

Conclusion: Systemic sclerosis phenotype, autoantibodies, complications, outcomes, malignancy rates, and mortality are generally similar between Hispanics and non-Hispanics with systemic sclerosis in the American Southwest. However, age-adjusted comorbid malignancy and mortality rates are significantly increased in both groups.

Gastrointestinal symptoms affect the great majority of patients with systemic sclerosis. Management of these complications is often challenging as any region of the gastrointestinal tract may be involved, and significant heterogeneity exists in clinical presentation, kinetics, and outcomes. Here, we highlight new findings relevant to the management of systemic sclerosis-related gastrointestinal disease (lights) and consider areas that we have yet to elucidate (shadows).

Background: The utility of nailfold capillaroscopy in the evaluation of patients without Raynaud's phenomenon is unclear.

Objective: This study aims to compare the utility of nailfold capillaroscopy for the early diagnosis of the scleroderma-spectrum of diseases in patients who present with Raynaud's phenomenon, undifferentiated non-Raynaud's phenomenon features and positive systemic sclerosis-associated antibodies without scleroderma-spectrum of disease features.

Methods: Eligible patients were divided into three referral criteria groups: (I) Raynaud's phenomenon; (II) Undifferentiated non-Raynaud's phenomenon features and (III) Positive systemic sclerosis-associated autoantibodies without features to suggest scleroderma-spectrum of diseases. This includes systemic sclerosis, mixed connective tissue disease and dermatomyositis. The association between baseline scleroderma pattern on nailfold capillaroscopy (systemic sclerosis-nailfold capillaroscopy) and final diagnosis at follow-up was determined using logistic regression analysis. Test characteristics of nailfold capillaroscopy were compared and stratified by referral groups.

Results: Of 95 patients followed-up for a mean of 1.6 years, 28 (29.5%) patients developed scleroderma-spectrum of diseases, 36 (37.9%) patients had suspected/other connective tissue disease and 27 (28.4%) patients had no connective tissue disease. Baseline systemic sclerosis-nailfold capillaroscopy was significantly associated with the development of scleroderma-spectrum of diseases in patients from Group I (odds ratio, 7.1, p = 0.01) and Group II (odds ratio 7.3, p = 0.005). In Group II patients, nailfold capillaroscopy had a sensitivity, specificity, positive and negative predictive values of 71.4%, 76.5%, 55.6% and 86.7%, respectively. Specificity (81.8%) and PPV (69.2%) were the highest in Group I patients. Nailfold capillaroscopy had the highest negative predictive value in Group III (100%), followed by Group II (86.7%) and Group I (78.3%) patients.

Conclusion: In addition to evaluating patients with Raynaud's phenomenon, nailfold capillaroscopy was useful in the evaluation and exclusion of scleroderma-spectrum of diseases in patients with undifferentiated non-Raynaud phenomenon features and those with systemic sclerosis-associated antibodies without features to suggest scleroderma-spectrum of diseases.

Systemic sclerosis is a multisystemic autoimmune disease characterized by vasculopathy and fibrosis. Racial factors exert a significant influence on the epidemiology, clinical manifestations, antibody profile, mortality and genetic factors in systemic sclerosis. In this review, we examined Asian systemic sclerosis cohorts reported in Asia and multi-racial cohort studies to evaluate the disease characteristics and outcomes of systemic sclerosis in Asians. Asian patients have distinct genetic susceptibility to systemic sclerosis, younger age of systemic sclerosis onset, higher frequency of diffuse skin involvement, different autoantibody profiles such as higher frequency of anti-Scl70 and anti-U1-RNP antibodies, and more severe clinical phenotype. There was a suggestion of poorer survival among Asians that may be contributed by more severe disease, socioeconomic factors and differences in healthcare systems. Recognizing the influence of racial differences in systemic sclerosis disease course is important as it has implications for appropriate treatment, monitoring and prognostication.

Systemic sclerosis is an autoimmune chronic sclerotic disease that can damage organs and cause serious complications for the patient such as musculoskeletal manifestations, Gastrointestinal involvement, pulmonary involvement, and renal disease. Acro-osteolysis is one of the musculoskeletal manifestations that causes corrosion of the bones in the fingertips of the hand and feet. In this paper, we have reported the rarely current evidence of severe Acro-osteolysis of the distal phalanges of the hands by radiological x-ray.

Objective: To explore the presence of small airway disease (SAD) and emphysema in scleroderma-related interstitial lung disease (SSc-ILD) and to evaluate the physiologic and clinical correlates of SAD in SSc-ILD.

Methods: Thoracic high-resolution computed tomography (HRCT) images obtained from the Scleroderma Lung Study II (SLSII) participants were reviewed by a group of thoracic radiologists. The presence of SAD was assessed by visual assessment for air trapping. HRCT scans were also evaluated for the presence of emphysema. The association of the presence of air trapping and emphysema with physiological measures of airway disease and clinical variables was evaluated.

Results: A total of 155 baseline HRCT scans were reviewed. For assessment of air trapping, images needed to be adequate end-expiratory examinations, leaving 123 scans. Air trapping was seen in 13/123 (10.6%) of the SSc-ILD cohort and was independent of smoking history, asthma or the presence of gastroesophageal reflux. Air trapping on HRCT was not associated with physiologic evidence of SAD. We also identified 8/155 (5.2%) patients with emphysema on HRCT, which was independent of SAD and found mostly in prior smokers.

Conclusion: We report the first study of air trapping on standardized, high-quality HRCT images as a reflection of SAD in a relatively large, well characterized SSc-ILD cohort. The presence of SAD in non-smoking SSc-ILD patients supports that SSc may cause not only restrictive lung disease (SSc-ILD), but also, to a lesser extent, obstructive disease. Physiologic measures alone may be inadequate to detect airway disease in patients with SSc-ILD.

Objectives: To explore shoulder findings by ultrasonography and to find factors associated with shoulder ultrasonographic abnormalities in systemic sclerosis patients.

Methods: A series of systemic sclerosis patients who attended the scleroderma clinic, Srinagarind Hospital, Faculty of Medicine, Khon Kaen University, Thailand, were prospectively evaluated for baseline characteristics, physical examination, and ultrasonography of both shoulders.

Results: Seventy-four systemic sclerosis patients were enrolled in this study. Diffuse cutaneous type of systemic sclerosis was the most common type (62.2%). The three common systemic sclerosis-associated symptoms were skin tightness (28.5%), salt-pepper appearance (20.9%), and telangiectasia (11.6%). The prevalence of shoulder pain in systemic sclerosis patients was 43.2% (32/74). Sixty-eight patients (92%) had abnormal ultrasonographic findings. The most common ultrasonographic abnormalities were unilateral calcification inside the glenohumeral joint (45.9%), bilateral calcification inside the glenohumeral joint (36.5%), and bilateral supraspinatus tendinosis (28.9%). Skin edematous was the only factor associated with abnormal shoulder ultrasonographic findings. No association between shoulder pain and abnormal shoulder ultrasonographic findings was detected.

Conclusion: Ultrasonographic abnormalities in the shoulder were common in the systemic sclerosis patients. The most frequent ultrasonographic finding of shoulder joints in systemic sclerosis patients was calcification inside the glenohumeral joint. Moreover, asymptomatic shoulder ultrasonographic abnormalities were prevalent in individuals with systemic sclerosis.

Objective: Pulmonary manifestations of systemic sclerosis are a major cause of morbidity and mortality. Small airways disease can cause dyspnea and pulmonary function test abnormalities. We aimed to determine the prevalence of small airways disease and describe the characteristics associated with small airways disease in a cohort of systemic sclerosis patients.

Methods: We performed a retrospective cohort study of adults with systemic sclerosis who met American College of Rheumatology/European League Against Rheumatism 2013 classification criteria and were evaluated at our institution between November 2000 and November 2015. Patients with prior lung transplantation were excluded. Small airways disease was defined as the presence of one or more of the following: airway-centered fibrosis on surgical lung biopsy, forced expiratory volume at 25-75% ⩽ 50% on pulmonary function tests, and/or high-resolution computed tomography scan of the chest with bronchiolitis, mosaic attenuation, or air trapping on expiratory views. The primary outcome was small airways disease diagnosis. We performed multivariable logistic regression to determine the association of clinical variables with small airways disease.

Results: One-hundred thirty-six systemic sclerosis patients were included; 55 (40%) had small airways disease. Compared to those without small airways disease, a significantly greater proportion of those with small airways disease had interstitial lung disease, chronic obstructive pulmonary disease, pulmonary hypertension, and gastroesophageal reflux disease. On multivariable analysis, pulmonary hypertension (odds ratio = 2.91, 95% confidence interval = 1.11-7.65, p-value = 0.03), gastroesophageal reflux disease (odds ratio = 2.70, 95% confidence interval = 1.08-6.79, p-value = 0.034), and anti-topoisomerase I (anti-Scl-70) antibody positivity (odds ratio = 0.42, 95% confidence interval = 0.19-0.93, p-value = 0.033) were associated with diagnosis of small airways disease.

Conclusion: Small airways disease is prevalent among systemic sclerosis patients; those with pulmonary hypertension or gastroesophageal reflux disease may have a higher risk of small airways disease.

Objective: Proton pump inhibitor-refractory reflux esophagitis is one of the intractable conditions of systemic sclerosis for which new treatments are required. Vonoprazan is a novel potassium-competitive acid blocker and has been shown to have several advantages over conventional proton pump inhibitors, including a long duration of gastric acid suppression.

Methods: To investigate the efficacy of vonoprazan for treating proton pump inhibitor-refractory reflux esophagitis in patients with systemic sclerosis, 10 patients with proton pump inhibitor-refractory reflux esophagitis who were switched to vonoprazan were selected from our systemic sclerosis database. Reflux esophagitis was evaluated by endoscopy, and gastroesophageal reflux disease-related symptoms were assessed by the frequency scale for the symptoms of gastroesophageal reflux disease questionnaire before and after switching from proton pump inhibitor to vonoprazan at an average interval of 3.5 [2-5.5] months.

Results: After switching patients to vonoprazan, the endoscopic findings of reflux esophagitis were significantly improved (p = .033), and six patients (60%) achieved mucosal healing. The total frequency scale for the symptoms of gastroesophageal reflux disease score was also significantly decreased (p = .043), mainly by improving the acid reflux score. Vonoprazan was well tolerated and was continued for 15.5 [11.25-23.75] months in all patients.

Conclusion: Vonoprazan is a potential treatment option for treating proton pump inhibitor-refractory reflux esophagitis in systemic sclerosis patients.
