The Collaborative National Quality and Efficacy Registry for Scleroderma: association of medication use on gastrointestinal tract symptoms in early disease and the importance of tobacco cessation.

OBJECTIVES: Systemic Sclerosis (SSc) is frequently associated with gastrointestinal tract (GIT) involvement. The Collaborative National Quality and Efficacy Registry (CONQUER) is a US-based collaborative study collecting longitudinal follow up data on SSc patients with less than 5-years disease duration enrolled at Scleroderma centres of excellence. This manuscript presents the GIT natural history and outcomes in relation to other scleroderma manifestations and medication exposures. METHODS: CONQUER participants that had completed a minimum of two serial Scleroderma Clinical Trials Consortium GIT Questionnaires (GIT 2.0) were included in this analysis. Patients were categorised by total GIT 2.0 severity at baseline, and by category change: none-to-mild (0.49); moderate (0.50-1.00), and severe-to-very severe (1.01-3.00) at the subsequent visit. Based on this data, four groups were identified: none-to-mild with no change, moderate-to-severe with no change, improvement, or worsening. Clinical features and medications, categorised as gastrointestinal tract targeted therapy, anti-fibrotic, immunosuppression, or immunomodulatory drugs, were recorded. Analysis included a proportional odds modelaccounting for linear and mixed effects of described variables. RESULTS: 415 enrolled CONQUER participants met project inclusion criteria. Most participants had stable mild GIT symptoms at baseline and were on immunomodulatory and anti-reflux therapy. In most patients, anti-reflux medication and immunosuppression initiation preceded the baseline visit, whereas anti-fibrotic initiation occurred at or after the baseline visit. In the proportional odds model, worsening GIT score at the follow-up visit was associated with current tobacco use (odds ratio: 3.48 (1.22, 9.98, p 0.020). CONCLUSIONS: This report from the CONQUER cohort, suggests that most patients with early SSc have stable and mild GIT disease. Closer follow-up was associated with milder, stable GIT symptoms. There was no clear association between immunosuppression or anti-fibrotic use and severity of GIT symptoms. However, active tobacco use was associated with worse GIT symptoms, highlighting the importance of smoking cessation counselling in this population.

Virtual Learning and Assessment in Rheumatology Fellowship Training: Objective Structured Clinical Examination Revisited.

OBJECTIVE: With the onset of the COVID-19 pandemic, an annual multi-institutional face-to-face rheumatology objective structured clinical examination (ROSCE) was transformed into a virtual format. The educational goals of the virtual ROSCE (vROSCE) were to reproduce the educational value of the previous in-person ROSCE, providing a valuable formative assessment of rheumatology training activities encompassing the 6 Accreditation Council for Graduate Medical Education (ACGME) core competencies for fellows-in-training (FITs). This article describes the novel design, feasibility, and stakeholder value of a vROSCE. METHODS: Through an established collaboration of 5 rheumatology fellowship training programs, in February 2021, a vROSCE was created and conducted using a Zoom platform. Station development included learning objectives, FIT instructions, faculty proctor instructions, and a checklist by which to provide structured formative feedback. An anonymous, optional web-based survey was sent to FIT participants to evaluate the experience. RESULTS: Twenty-three rheumatology FITs from 5 institutions successfully rotated through 6 stations in the vROSCE. Immediate feedback was given to each FIT using standardized rubrics structured around ACGME core competencies. A total of 65% of FITs (15 of 23) responded to the survey, and 93% of survey respondents agreed or strongly agreed that the vROSCE was a helpful educational activity and identified individualized opportunities for improvement. CONCLUSION: A vROSCE is an innovative, feasible, valuable, and well-received educational technology tool. The vROSCE enriched rheumatology FITs' education and offered collaborative learning experiences across institutions.

CONQUER Scleroderma: association of gastrointestinal tract symptoms in early disease with resource utilization.

OBJECTIVES: SSc is associated with increased health-care resource utilization and economic burden. The Collaborative National Quality and Efficacy Registry (CONQUER) is a US-based collaborative that collects longitudinal follow-up data on SSc patients with <5 years of disease duration enrolled at scleroderma centres in the USA. The objective of this study was to investigate the relationship between gastrointestinal tract symptoms and self-reported resource utilization in CONQUER participants. METHODS: CONQUER participants who had completed a baseline and 12-month Gastrointestinal Tract Questionnaire (GIT 2.0) and a Resource Utilization Questionnaire (RUQ) were included in this analysis. Patients were categorized by total GIT 2.0 severity: none-to-mild (0-0.49); moderate (0.50-1.00), and severe-to-very severe (1.01-3.00). Clinical features and medication exposures were examined in each of these categories. The 12-month RUQ responses were summarized by GIT 2.0 score categories at 12 months. RESULTS: Among the 211 CONQUER participants who met the inclusion criteria, most (64%) had mild GIT symptoms, 26% had moderate symptoms, and 10% severe GIT symptoms at 12 months. The categorization of GIT total severity score by RUQ showed that more upper endoscopy procedures and inpatient hospitalization occurred in the CONQUER participants with severe GIT symptoms. These patients with severe GIT symptoms also reported the use of more adaptive equipment. CONCLUSION: This report from the CONQUER cohort suggests that severe GIT symptoms result in more resource utilization. It is especially important to understand resource utilization in early disease cohorts when disease activity, rather than damage, primarily contributes to health-related costs of SSc.

Training the Next Generation of Rheumatologists: What Is the Best Way to Teach Fellows About Scleroderma?

Rheumatology is rich in educational opportunities, learning about a variety of diseases. Rheumatology subspecialty training is a time of unparalleled learning, and within the curriculum of a training program, the connective tissue diseases (CTDs) represent a unique challenge to the fellows. The challenge therein lies in the multisystem presentations they are faced with mastering. Scleroderma, as a rare and life-threatening CTD, remains one of the most difficult conditions to manage and treat. In this article, the authors focus on an approach to training the next generation of rheumatologists to take care of patients with scleroderma.

Computed Tomography of the Chest to Screen for Interstitial Lung Disease in Patients With Systemic Sclerosis at Expert Scleroderma Centers in the United States.

OBJECTIVE: Although a high-resolution computed tomography (HRCT) scan of the chest is the gold standard test for the detection of interstitial lung disease (ILD), there is no consensus among rheumatologists regarding the use of HRCT to screen for ILD in their patients with systemic sclerosis (SSc). The aims of this study were to describe the HRCT ordering practices at SSc centers in the United States and to determine which patient characteristics are associated with HRCT performance. METHODS: We performed a prospective cohort study of patients with SSc enrolled in the US-based Collaborative National Quality and Efficacy Registry (CONQUER). We performed univariate logistic regression followed by multivariable logistic regression to determine which patient characteristics were associated with HRCT performance. RESULTS: Of the 356 patients with SSc enrolled in CONQUER, 286 (80.3%) underwent HRCT at some point during their disease course. On multivariable analyses, missing total lung capacity percent predicted (odds ratio [OR] 3.26, 95% confidence interval [CI]: 1.53-7.41, P = 0.007) was positively associated with ever having undergone HRCT, whereas a positive anti-centromere antibody (OR 0.27, 95% CI: 0.12-0.61, P = 0.008) and missing forced vital capacity percent predicted (OR 0.29, 95% CI: 0.10-0.80, P = 0.005) were negatively associated with ever having undergone HRCT. There was a trend toward a positive association between crackles on pulmonary exam and ever having undergone HRCT (OR 2.28, 95% CI: 0.97-6.05, P = 0.058), although this relationship did not reach statistical significance. CONCLUSION: The majority of patients with SSc enrolled in CONQUER underwent HRCT. A positive anti-centromere antibody was the key clinical variable inversely associated with performance of HRCT.

Baseline characteristics of systemic sclerosis patients with restrictive lung disease in a multi-center US-based longitudinal registry.

AIM: Interstitial lung disease (ILD) is the leading cause of disease-related death in systemic sclerosis (SSc). Here, we assess baseline characteristics of SSc subjects with and without restrictive lung disease (RLD) in a multi-center, US-based registry. METHODS: SSc patients within 5 years of disease onset were enrolled in the Collaborative National Quality and Efficacy Registry (CONQUER), a multi-center US-based registry of SSc study participants (age ≥ 18 years) enrolled at 13 expert centers. All subjects met 2013 American College of Rheumatology / European League Against Rheumatism criteria. Subjects with a pulmonary function test (PFT) at baseline before April 1, 2020 were included. High-resolution computed tomography scan of the chest was not available to characterize ILD for all subjects. RLD was defined as forced vital capacity (FVC) <80% or total lung capacity (TLC) <80% predicted. RESULTS: There were 160 (45%) SSc subjects characterized as having RLD. There was no significant difference in age, gender or disease duration. RLD subjects had a mean disease duration from date of first non-Raynaud's symptom of 2.6 years and a mean FVC% predicted of 67% at baseline. In multivariable analysis, non-White race, higher physician global health assessment and modified Medical Research Council (mMRC) dyspnea scores, were independently associated with RLD. In the subgroup of RLD subjects with ILD, ILD had a negative correlation with RNA polymerase III antibody. CONCLUSION: CONQUER is the largest, multi-center, prospective cohort of early SSc patients in the US. Non-White race was independently associated with RLD. In addition, 45% of CONQUER subjects already had RLD, highlighting the importance of screening for SSc-ILD at initial diagnosis.

Does hand involvement in systemic sclerosis limit completion of patient-reported outcome measures?

The objective of this analysis is to examine whether the severity of systemic sclerosis (SSc)-hand involvement influences patient-reported outcome measure (PROM) completion rate in a US cohort of early disease. Participants included SSc patients with less than 5 years disease duration consented and enrolled in the Collaborative, National, Quality, and Efficacy Registry (CONQUER) between June 2018 and December 2019. Participants' socio-demographics, hand clinical features (severe modified Rodnan skin score, presence of small joint contractures, acro-osteolysis, calcinosis, and digital ulcers), and completion rates of seven PROMs including a Resource Use Questionnaire were analyzed. Cohort characteristics and baseline PROM completion were evaluated. Multivariable logistic regression assessed the relationship between hand limitations and PROM incompletion at several time points using generalized estimating equations. At the time of data lock, 339 CONQUER subjects had a total of 600 visits available for analysis. Calcinosis (odds ratio [OR] 6.35, confidence interval [CI] 2.41-16.73 and acro-osteolysis OR 3.88 (1.57-9.55) were significantly associated with incomplete PROM. The Resource Use Questionnaire was the PROM most commonly not completed. Increasing age was correlated with resource use questionnaire incompletion rate. Acro-osteolysis and calcinosis were associated with lower PROM completion rates in a US SSc cohort, independent of the length of the questionnaires or the modality of administration (electronic or paper). Resource Use Questionnaires are important for understanding the economic impact and burden of chronic disease; however, in this study, it had lower completion rates than PROMs devoted to clinical variables. Key points •Multiple strategies are needed to ensure optimal completion of PROM in longitudinal cohort studies. Even if patients request electronic surveys, we have found it is important to follow up incomplete surveys with paper forms provided at the time of a clinical visit. •The Resource Utilization Questionnaire was lengthy and prone to non-completion in the younger population. •Acro-osteolysis and calcinosis were associated with reduced PROM completion rates.

Predictive Significance of Serum Interferon-Inducible Protein Score for Response to Treatment in Systemic Sclerosis-Related Interstitial Lung Disease.

OBJECTIVE: Response to immunosuppression is highly variable in systemic sclerosis (SSc)-related interstitial lung disease (ILD). This study was undertaken to determine whether a composite serum interferon (IFN)-inducible protein score exhibits predictive significance for the response to immunosuppression in SSc-ILD. METHODS: Serum samples collected in the Scleroderma Lung Study II, a randomized controlled trial of mycophenolate mofetil (MMF) versus cyclophosphamide (CYC), were examined. Results were validated in an independent observational cohort receiving active treatment. A composite score of 6 IFN-inducible proteins IFNγ-inducible 10-kd protein, monokine induced by IFNγ, monocyte chemotactic protein 2, ß2 -microglobulin, tumor necrosis factor receptor type II, and macrophage inflammatory protein 3ß) was calculated, and its predictive significance for longitudinal forced vital capacity percent predicted measurements was evaluated. RESULTS: Higher baseline IFN-inducible protein score predicted better response over 3 to 12 months in the MMF arm (point estimate = 0.41, P = 0.001) and CYC arm (point estimate = 0.91, P = 0.009). In contrast, higher baseline C-reactive protein (CRP) levels were predictive of a worse ILD course in both treatment arms. The predictive significance of the IFN-inducible protein score and CRP levels remained after adjustment for baseline demographic and clinical predictors. During the second year of treatment, in which patients in the CYC arm were switched to placebo, a higher IFN-inducible protein score at 12 months showed a trend toward predicting a worse ILD course (point estimate = -0.61, P = 0.068), while it remained predictive of better response to active immunosuppression in the MMF arm (point estimate = 0.28, P = 0.029). The predictive significance of baseline IFN-inducible protein score was replicated in the independent cohort (rs = 0.43, P = 0.028). CONCLUSION: A higher IFN-inducible protein score in SSc-ILD is predictive of better response to immunosuppression and could potentially be used to identify patients who may derive the most benefit from MMF or CYC.

Performance Characteristics of Pulmonary Function Tests for the Detection of Interstitial Lung Disease in Adults With Early Diffuse Cutaneous Systemic Sclerosis.

OBJECTIVE: Interstitial lung disease (ILD) is the leading cause of death in patients with systemic sclerosis (SSc). Although pulmonary function tests (PFTs) are commonly used to screen for ILD in patients with SSc, studies have shown that they lack sensitivity for the detection of ILD in general SSc cohorts. This study was undertaken to assess the performance characteristics of PFTs for the detection of ILD in patients with early diffuse cutaneous SSc (dcSSc), a population at high risk for the development of ILD. METHODS: We performed a retrospective cohort study of patients enrolled in the Prospective Registry of Early Systemic Sclerosis at 11 sites in the US between April 2012 and January 2019. Patients were included if they underwent spirometry and high-resolution computed tomography (HRCT) of the chest. We calculated the performance characteristics of PFTs for the detection of ILD on HRCT. RESULTS: The study included 212 patients, 54% of whom had radiographic ILD. For the detection of ILD on HRCT imaging, a forced vital capacity (FVC) <80% predicted had a sensitivity of 63%. The combination of FVC <80% predicted or diffusing capacity for carbon monoxide (DLco) <80% predicted improved the sensitivity to 85%. An FVC <80% predicted had a negative predictive value (NPV) of 61%, while the combination of FVC <80% predicted or DLco <80% predicted had an NPV of 70%. CONCLUSION: PFTs alone are an inadequate screening tool for the diagnosis of ILD in patients with early dcSSc. HRCT should be part of the ILD screening algorithm in patients with dcSSc.

Safety and efficacy of abatacept in early diffuse cutaneous systemic sclerosis (ASSET): open-label extension of a phase 2, double-blind randomised trial.

BACKGROUND: Abatacept was well tolerated by patients with early diffuse cutaneous systemic sclerosis in a phase 2, double-blind randomised trial, with potential efficacy at 12 months. We report here the results of an open-label extension for 6 months. METHODS: Patients (aged ≥18 years) with diffuse cutaneous systemic sclerosis of less than 3 years' duration from their first non-Raynaud's symptom were enrolled into the ASSET trial (A Study of Subcutaneous Abatacept to Treat DiffuseCutaneous Systemic Sclerosis), which is a double-blind trial at 22 sites in Canada, the UK, and the USA. Aftercompletion of 12 months of treatment with either abatacept or placebo, patients received a further 6 months ofabatacept (125 mg subcutaneous every week) in an open-label extension. The primary endpoint of the double-blind trial was modified Rodnan Skin Score (mRSS) at 12 months, which was reassessed at 18 months in the open-label extension. The primary analysis included all participants who completed the double-blind trial and received at least one dose of open-label treatment (modified intention to treat). This trial is registered with ClinicalTrials.gov, NCT02161406. FINDINGS: Between Sept 22, 2014, and March 15, 2017, 88 participants were randomly allocated in the double-blind trial either abatacept (n=44) or placebo (44); 32 patients from each treatment group completed the 6-month open-labelextension. Among patients assigned abatacept, a mean improvement from baseline in mRSS was noted at 12 months (-6·6 [SD 6·4]), with further improvement seen during the open-label extension period (-9·8 [8·1] at month 18). Participants assigned placebo had a mean improvement from baseline in mRSS at 12 months (-3·7 [SD 7·6]), with a further improvement at month 18 (-6·3 [9·3]). Infections during the open-label extension phase occurred in nine patients in the placebo-abatacept group (12 adverse events, one serious adverse event) and in 11 patients in theabatacept-abatacept group (14 adverse events, one serious adverse event). Two deaths occurred during the 12-month double-blind period in the abatacept group, which were related to scleroderma renal crisis; no deaths were recorded during the open-label extension. INTERPRETATION: During the 6-month open-label extension, no new safety signals for abatacept were identified in the treatment of diffuse cutaneous systemic sclerosis. Clinically meaningful improvements in mRSS and other outcome measures were observed in both the abatacept and placebo groups when patients transitioned to open-label treatment. These data support further studies of abatacept in diffuse cutaneous systemic sclerosis. FUNDING: Bristol-Myers Squibb and National Institutes of Health.

Abatacept in Early Diffuse Cutaneous Systemic Sclerosis: Results of a Phase II Investigator-Initiated, Multicenter, Double-Blind, Randomized, Placebo-Controlled Trial.

OBJECTIVE: T cells play a key role in the pathogenesis of early systemic sclerosis. This study was undertaken to assess the safety and efficacy of abatacept in patients with diffuse cutaneous systemic sclerosis (dcSSc). METHODS: In this 12-month, randomized, double-blind, placebo-controlled trial, participants were randomized 1:1 to receive either subcutaneous abatacept 125 mg or matching placebo, stratified by duration of dcSSc. Escape therapy was allowed at 6 months for worsening disease. The coprimary end points were change in the modified Rodnan skin thickness score (MRSS) compared to baseline and safety over 12 months. Differences in longitudinal outcomes were assessed according to treatment using linear mixed models, with outcomes censored after initiation of escape therapy. Skin tissue obtained from participants at baseline was classified into intrinsic gene expression subsets. RESULTS: Among 88 participants, the adjusted mean change in the MRSS at 12 months was -6.24 units for those receiving abatacept and -4.49 units for those receiving placebo, with an adjusted mean treatment difference of -1.75 units (P = 0.28). Outcomes for 2 secondary measures (Health Assessment Questionnaire disability index and a composite measure) were clinically and statistically significantly better with abatacept. The proportion of subjects in whom escape therapy was needed was higher in the placebo group relative to the abatacept group (36% versus 16%). In the inflammatory and normal-like skin gene expression subsets, decline in the MRSS over 12 months was clinically and significantly greater in the abatacept group versus the placebo group (P < 0.001 and P = 0.03, respectively). In the abatacept group, adverse events occurred in 35 participants versus 40 participants in the placebo group, including 2 deaths and 1 death, respectively. CONCLUSION: In this phase II trial, abatacept was well-tolerated, but change in the MRSS was not statistically significant. Secondary outcome measures, including gene expression subsets, showed evidence in support of abatacept. These data should be confirmed in a phase III trial.

Collaborative National Quality and Efficacy Registry (CONQUER) for Scleroderma: outcomes from a multicenter US-based systemic sclerosis registry.

The Collaborative National Quality and Efficacy Registry (CONQUER) for Scleroderma is a multicenter US-based longitudinal study of patients with systemic sclerosis (SSc) within 5 years of first non-Raynaud's symptom. The data collection methodology incorporates successful models from other SSc registries. The cohort is designed to provide linked bio-specimen and clinical outcomes data on a longitudinal cohort of SSc patients for validation of hypothesis-driven research and to provide a platform for studying patient-reported outcomes in scleroderma. The CONQUER registry was developed using the guidelines of the International Society for Biological Repositories, and was an iterative process between physicians with an expertise in SSc, patient stakeholders, and information technology experts. Enrollment commenced in June 2018. During the first 6 months of the CONQUER Scleroderma study, 151 SSc patients with less than 5 years of disease duration (from first non-Raynaud's symptom) have been recruited. The mean age is 51 ± 14 years, 83% are female, and 60% of patients have diffuse disease. Survey completion rates are above 88% for all patient-reported outcome surveys. Bio-specimen collection rates are over 97%, and disease severity score completion rates are over 98%. Pulmonary function test data is available on 91% of patients, and echocardiography is available 80%. The CONQUER scleroderma study provides a unique and growing resource for studying scleroderma in a longitudinal, US-based population. KEY POINTS : • The Collaborative National Quality and Efficacy Registry (CONQUER) for Scleroderma is a multicenter US-based longitudinal study of patients with systemic sclerosis (SSc) within 5 years of first non-Raynaud's symptom. • The CONQUER scleroderma study provides a unique and growing resource for studying scleroderma in a longitudinal, US-based population. • CONQUER is innovative in its design in that it is focused on prospective collection of paired clinical and patient outcome data with bio-specimens.

Global skin gene expression analysis of early diffuse cutaneous systemic sclerosis shows a prominent innate and adaptive inflammatory profile.

OBJECTIVES: Determine global skin transcriptome patterns of early diffuse systemic sclerosis (SSc) and how they differ from later disease. METHODS: Skin biopsy RNA from 48 patients in the Prospective Registry for Early Systemic Sclerosis (PRESS) cohort (mean disease duration 1.3 years) and 33 matched healthy controls was examined by next-generation RNA sequencing. Data were analysed for cell type-specific signatures and compared with similarly obtained data from 55 previously biopsied patients in Genetics versus Environment in Scleroderma Outcomes Study cohort with longer disease duration (mean 7.4 years) and their matched controls. Correlations with histological features and clinical course were also evaluated. RESULTS: SSc patients in PRESS had a high prevalence of M2 (96%) and M1 (94%) macrophage and CD8 T cell (65%), CD4 T cell (60%) and B cell (69%) signatures. Immunohistochemical staining of immune cell markers correlated with the gene expression-based immune cell signatures. The prevalence of immune cell signatures in early diffuse SSc patients was higher than in patients with longer disease duration. In the multivariable model, adaptive immune cell signatures were significantly associated with shorter disease duration, while fibroblast and macrophage cell type signatures were associated with higher modified Rodnan Skin Score (mRSS). Immune cell signatures also correlated with skin thickness progression rate prior to biopsy, but did not predict subsequent mRSS progression. CONCLUSIONS: Skin in early diffuse SSc has prominent innate and adaptive immune cell signatures. As a prominently affected end organ, these signatures reflect the preceding rate of disease progression. These findings could have implications in understanding SSc pathogenesis and clinical trial design.

Progression of Interstitial Lung Disease in Systemic Sclerosis: The Importance of Pneumoproteins Krebs von den Lungen 6 and CCL18.

OBJECTIVE: To investigate the relationship between Krebs von den Lungen 6 (KL-6) and CCL18 levels and the severity and progression of systemic sclerosis (SSc)-related interstitial lung disease (ILD). METHODS: Patients enrolled in the Scleroderma Lung Study II (cyclophosphamide [CYC] versus mycophenolate mofetil [MMF]) were included. Baseline and 12-month plasma samples were analyzed by enzyme-linked immunosorbent assay to assess CCL18 and KL-6 levels. The forced vital capacity (FVC) and the diffusing capacity for carbon monoxide (DLco) were measured every 3 months. Joint models were created to investigate the relationship between baseline CCL18 and KL-6 levels and the course of the FVC and DLco over 1 year according to treatment arm. RESULTS: Baseline KL-6 and CCL18 levels each correlated with the extent of radiographic fibrosis. Levels of both CCL18 and KL-6 declined significantly at 1 year. In both treatment arms (n = 71 for CYC, n = 62 for MMF), a higher baseline KL-6 level predicted progression of ILD based on the course of FVC (P = 0.024 for CYC; P = 0.005 for MMF) and DLco (P < 0.001 for CYC; P = 0.004 for MMF) over 1 year. A higher baseline CCL18 level predicted progression of ILD based on the course of the FVC (P < 0.001 for CYC; P = 0.007 for MMF) and DLco (P = 0.001 for CYC; P < 0.001 for MMF) over 1 year, as well as mortality (P = 0.0008 for CYC arm only). CONCLUSION: In a rigorously conducted clinical trial for SSc-related ILD, KL-6 and CCL18 levels correlated with ILD severity and declined with immunosuppression. Patients with higher baseline KL-6 and CCL18 levels were more likely to experience disease progression despite treatment. KL-6 and CCL18 levels could be used to identify patients with a progressive ILD phenotype who may benefit from a more aggressive initial treatment approach.

Risk Factors for Mortality and Cardiopulmonary Hospitalization in Systemic Sclerosis Patients At Risk for Pulmonary Hypertension, in the PHAROS Registry.

OBJECTIVE: We sought to identify predictors of mortality and cardiopulmonary hospitalizations in patients at risk for pulmonary hypertension (PH) and enrolled in PHAROS, a prospective cohort study to investigate the natural history of PH in systemic sclerosis (SSc). METHODS: The at-risk population for PH was defined by the following entry criteria: echocardiogram systolic pulmonary arterial pressure > 40 mmHg, or DLCO < 55% predicted or ratio of % forced vital capacity/%DLCO > 1.6, measured by pulmonary function testing. Baseline clinical measures were evaluated as predictors of hospitalization and death between 2005 and 2014. Cox proportional hazards models were censored at date of PH onset or latest study visit and adjusted for age, sex, race, and disease duration. RESULTS: Of the 236 at-risk subjects who were followed for a median of 4 years (range 0.4-8.5 yrs), 35 developed PH after entering PHAROS (reclassified as PH group). In the at-risk group, higher mortality was strongly associated with male sex, low %DLCO, exercise oxygen desaturation, anemia, abnormal dyspnea scores, and baseline pericardial effusion. Risks for cardiopulmonary hospitalization were associated with increased dyspnea and pericardial effusions, although PH patients with DLCO < 50% had the highest risk of cardiopulmonary hospitalizations. CONCLUSION: Risk factors for poor outcome in patients with SSc who are at risk for PH were similar to others with SSc-PH and SSc-pulmonary arterial hypertension, including male sex, DLCO < 50%, exercise oxygen desaturation, and pericardial effusions. This group should undergo right heart catheterization and receive appropriate intervention if PH is confirmed.

Review of Current Immunologic Therapies for Hidradenitis Suppurativa.

Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory disease of apocrine gland-bearing skin which affects approximately 1-4% of the population. The disease is more common in women and patients of African American descent and approximately one-third of patients report a family history. Obesity and smoking are known risk factors, but associations with other immune disorders, especially inflammatory bowel disease, are also recognized. The pathogenesis of HS is poorly understood and host innate or adaptive immune response, defective keratinocyte function, and the microbial environment in the hair follicle and apocrine gland have all been postulated to play a role in disease activity. While surgical interventions can be helpful to reduce disease burden, there is a high recurrence rate. Increasingly, data supports targeted immune therapy for HS, and longitudinal studies suggest benefit from these agents, both when used alone and as an adjunct to surgical treatments. The purpose of this review is to outline the current data supporting use of targeted immune therapy in HS management.

Reliability and Validity of the Tender and Swollen Joint Counts and the Modified Rodnan Skin Score in Early Diffuse Cutaneous Systemic Sclerosis: Analysis from the Prospective Registry of Early Systemic Sclerosis Cohort.

OBJECTIVE: To determine the inter/intraobserver reliability of the tender and swollen joint counts (TJC, SJC) and the modified Rodnan Skin Score (mRSS) in diffuse cutaneous systemic sclerosis (dcSSc) and to assess content validity of the TJC/SJC. METHODS: Ten rheumatologists completed the SJC, TJC, and mRSS on 7 patients. Musculoskeletal ultrasound (MSUS) was performed. RESULTS: Interobserver and intraobserver reliability for the TJC was 0.97 and 0.99, for the SJC was 0.24 and 0.71, and for the mRSS was 0.81 and 0.94, respectively. MSUS abnormalities did not correspond with SJC/TJC. CONCLUSION: We demonstrate excellent inter- and intraobserver reliability for the mRSS and TJC in dcSSc. However, the SJC and TJC did not correspond to MSUS.

Systemic Sclerosis and Perceptions of Quality in Primary Care.

BACKGROUND: Among patients with systemic sclerosis (SSc), early recognition of potentially life-threatening organ involvement is critical. Because prompt recognition of early signs of organ involvement can dramatically alter a patient׳s outcome, it is crucial that patients and primary care providers (PCPs) recognize these symptoms. We conducted a survey of patients with SSc regarding their perceptions of the quality of their primary care, and whether or not they perceive the quality of their primary care to be impaired by their scleroderma diagnosis. MATERIALS AND METHODS: A mail survey was sent to 525 patients with SSc seen at the Medical University of South Carolina. Questionnaire items addressed demographics and perceptions of their quality of their primary care. RESULTS: Of n = 140 respondents, most (74.5%) did not feel as though their diagnosis of SSc has resulted in barriers to appropriate or satisfactory care, and most (81.3%) answered that they had not ever felt as though their medical concerns were not being addressed because they had SSc. Perceptions of barriers were significantly (P < 0.05) associated with female sex and younger age, along with poorer overall quality of care and satisfaction with their primary care. CONCLUSIONS: Most patients with SSc value the quality of their primary care. However, some patients with SSc feel that their PCPs do not adequately monitor their blood pressure, reflux symptoms or shortness of breath. These results highlight the importance of PCPs in the overall care of patients with SSc and the need for continued education regarding close monitoring of signs and symptoms suggestive of possible life-threatening internal organ involvement.

Drugs that may harm bone: Mitigating the risk.

Glucocorticoids, proton pump inhibitors, selective serotonin reuptake inhibitors (SSRIs), certain antiepileptic drugs, and aromatase inhibitors have significant adverse effects on bone. Healthcare providers should monitor the bone health of patients on these agents, supplement their intake of calcium and vitamin D, encourage weight-bearing exercise, and initiate osteoporosis-prevention treatment as indicated.
