Methods Baseline characteristics and 1 year follow-up results of patients with SSc referred to a multidisciplinary healthcare programme were evaluated.

Progressive disease was defined as: death, 10 decrease in forced vital capacity, 15 decrease in diffusing capacity for carbon monoxide, 10 decrease in body weight, 30 decrease in estimated-glomerular filtration rate, 30 increase in modified Rodnan Skin Score with 5 or 0.

The number of patients with progressive disease was determined. Univariable and multivariable logistic regression analyses were used to assess the probability of progressive disease for each individual patient. Performance of the prediction model was evaluated using a calibration plot and area under the receiver operating characteristic curve. Results 63 patients had progressive disease, including 8 patients who died 18 months after first evaluation.

Multivariable analysis showed that friction rubs, proximal muscular weakness and decreased maximum oxygen uptake as predicted, adjusted for age, gender and use of immunosuppressive therapy at baseline, were significantly associated with progressive disease. Using the prediction model, the predicted chance for progressive disease increased from a pretest chance of 37 to Conclusions Using the prediction model, the chance for progressive disease for individual patients could be doubled.

Friction rubs, proximal muscular weakness and maximum oxygen uptake as predicted were identified as relevant parameters. Few studies have described algorithms on an individualised basis to predict mortality after 2 to 15 years of follow-up in systemic sclerosis SSc. What does this study add A prediction model assessing the chance for progressive disease for individual patients at short term was currently developed. How might this impact on clinical practice Using the prediction model, the predicted chance for progressive disease could be doubled from a pretest chance of 37 to Introduction Individualised management and treatment is one of the most important challenges in medicine.

Systemic sclerosis SSc is a rare multisystem disease which is highly heterogeneous in presentation and disease course. Recent evidence suggests that earlier initiation of adequate treatment based on regular screening for organ involvement contributes to improved survival. Given the associated treatment-related mortality during the first year, this treatment option underlines the need to identify patients with a high risk of severe organ involvement in the short term.

Numerous attempts have been made to identify predictors for severe organ involvement and mortality in SSc. In contrast, a recently published study containing observational data from the EUSTAR database described a model identifying, among patients with diffuse cutaneous SSc, those with a 44 chance of skin fibrosis progression during the first year, as compared to 9.

Whether it is possible to reliably identify patients at risk using such a model, given the heterogeneous nature of SSc, remains to be determined. The present study aimed to develop a model that predicts progressive disease in the short term, defined by either deterioration of organ functions, or mortality, in patients with SSc.

The derived prediction model is evaluated for discriminative performance, and a cut-off value is determined in order to evaluate utility in clinical practice. Patients and methods Study design This study is performed using data from a prospective cohort study in patients with SSc who participated in an annual 2-day multidisciplinary healthcare programme aiming to structure screening for organ involvement and to provide multidisciplinary care for patients with SSc.

All participants gave written informed consent. Patients Data from all patients referred to the multidisciplinary healthcare programme between April and January were collected. Patients were classified on the basis of their maximum skin score ever. For example, if a patient had had a skin score of 30 and underwent HSCT after which the skin score decreased to 6, the patient was still classified as DcSSc.

For the current analysis, selected patients had to have participated in the care programme at least twice, with the second visit 1 year after the baseline visit range months. Multidisciplinary healthcare programme All patients participated in the healthcare programme that combines annual extensive organ screening with multidisciplinary team care.

Cardiopulmonary investigations included: high-resolution CT HRCT of the thorax, pulmonary function tests including analyses of forced vital capacity FVC and diffusing capacity for carbon monoxide DLCO , cardiopulmonary exercise test CPET including analyses of maximum heart rate, maximum wattage, maximum oxygen consumption VO2 and maximum ventilation , echocardiography and 24 h Holter electrocardiography ECG.

Furthermore, laboratory investigations including measurement of autoantibodies and nailfold videocapillaroscopy were performed. Diagnosis of interstitial lung disease ILD was determined on the basis of the presence of a non-specific interstitial pneumonia pattern or usual interstitial pneumonia pattern on the HRCT-thorax,21 as reported by the radiologist. The systolic pulmonary artery pressure SPAP was estimated using echocardiography by an experienced cardiologist and elevated pulmonary pressure is defined using a cut-off value of 35 mm Hg.

Furthermore, the presence of pericardial effusion was noted. The presence of arrhythmias was defined as the presence of multiform ventricular extrasystole gt per day, couplets or runs of ventricular tachycardia or supraventricular tachycardia of at least 30 s on 24 h Holter ECG monitoring. Rituximab is given as part of a randomised placebo-controlled clinical trial RITIS , registered at www. Progressive disease Since we aimed to define risk for progressive disease in general, in order to guide clinical management, several variables were chosen, each reflecting a different organ system.

Cut-offs for these variables were based on reported values for minimal important difference MID. Selected variables were: 1 death before the second visit 2 decrease of 10 in FVC percentage of predicted 16 3 decrease of 15 in DLCO percentage of predicted 16 4 decrease of 10 in body weight24 5 decrease of 30 in estimated-glomerular filtration rate eGFR 25 6 increase of 30 in modified Rodnan Skin Score mRSS with a minimum of Statistical analysis Associations between baseline variables and the presence of progressive disease were evaluated and expressed as ORs with the 95 CIs and p values.

Missing values of variables used to define overall progressive disease and baseline predictors were replaced by multiple imputation using multiple regression modelling by the multiple imputations by chained equations procedure as implemented in SPSS. Therefore, VO2 max was not imputed and the missing-indicator method was used. Univariable logistic regression analysis was used to determine the independent association between baseline characteristics and overall progressive disease after 1 year of follow-up.

Therefore, VO2 max was not imputed and the missing-indicator method was used. Univariable logistic regression analysis was used to determine the independent association between baseline characteristics and overall progressive disease after 1 year of follow-up.

Possible correlations between all variables which were significantly contributing in the univariable logistic regression analyses were checked for multicollinearity using a variance inflation factor VIF of For the multivariable model, all predictor variables with a p value smaller than 0. Univariable and multivariable logistic regression analyses were always adjusted for previous and current immunosuppressive therapy including cyclophosphamide, methotrexate and HSCT at baseline.

Multivariable logistic regression analysis was adjusted for age and gender. The predicted probability of progressive disease was calculated for every patient. The predicted probabilities were compared with the observed percentage of patients with progressive disease.

The positive predictive value PPV and negative predictive value NPV were determined for several cut-off values of the predicted probability. The predictive performance of the model was assessed by examining measures of calibration and discrimination. Calibration refers to how close predicted progressive disease agrees with observed progressive disease and was assessed with a calibration plot.

For internal validation, a bootstrap procedure was performed for control for overfitting. Results Patient population By January , patients with SSc had had a second evaluation after a mean period of Eight patients died before the second visit could have been performed. Baseline characteristics of the included patients are presented in table 1. The patients were mostly women 80 , Caucasian 70 and, on average, 53 years SD Patients had a median disease duration of 2 years.

Baseline characteristics of the systemic sclerosis population with a baseline visit and 1 year follow-up At baseline, 63 39 patients were treated with immunosuppressive medication, including 55 32 patients who were previously treated with one or more immunosuppressive medications including autologous HSCT n13 , cyclophosphamide n18 , corticosteroids n28 , methotrexate MTX n28 and AZA n2 , HCQ n2 and 60 35 patients currently being treated with immunosuppressive medication, including mycophenolate mofetil MMF n6 , corticosteroids n24 , MTX n22 , AZA n5 and HCQ n7.

Change of treatment On the basis of the findings during the multidisciplinary healthcare programme, new immunosuppressive treatment one or more medications was started at baseline in 37 patients In none of the patients with previous HSCT was new immunosuppressive medication started. Mortality Within 1 year after the first visit, eight patients mean age Three patients died due to ILD, one due to PAH, one due to adenocarcinoma of the lung in a non-smoker , one due to cardiac failure and one due to cytomegalovirus pneumonitis after allogeneic SCT.

In one patient died at age 87 years after suffering from renal disease , the exact cause of death could not be determined. All patients were classified as those with progressive disease, since for none of the patients could an association between SSc and death be ruled out with absolute certainty. Progressive disease Sixty-three patients showed overall progressive disease at follow-up evaluation according to the predefined criteria, including eight patients who died table 2.

Incidence of progressive disease in SSc according to SSc subtype Progressive disease, N The organ systems and number of prespecified outcomes contributing to overall progressive disease are demonstrated in online supplementary figure 1. The majority of the patients 71 had overall progressive disease based on one event, while in 13 of the patients two events and in 3 of the patients three events contributed to overall progressive disease.

Missing values Age, gender, disease subset, SSc-related autoantibodies, friction rubs, proximal muscular weakness, eGFR, ESR and body weight were available for all patients. CPET was not performed in 11 patients due to an inability to cycle based on bad physical performance N4 and musculoskeletal disability N2. Prediction of progressive disease Univariable analyses Table 3 shows results of the univariable logistic regression analysis, adjusted for previous and current immunosuppressive therapy.

FVC and gender were borderline significant p value lt0. However, the multivariable logistic regression analysis for patients with LcSSc did not identify significant predictors for progressive disease see online supplementary material file. Multivariable analyses and derivation of the prediction model In the multivariable logistic regression analysis, independent predictive variables for progressive disease were friction rubs, proximal muscular weakness, VO2 max predicted and immunosuppressive therapy.

OR for progressive disease increased with A missing VO2 max was accompanied by its corresponding missing indicator variable. The coefficients for the prediction model are listed in table 4. Independent predictive variables for progressive disease based on multivariable logistic regression analysis The multivariable model remained unchanged when adding the borderline significant variable in the univariable analysis: FVC was excluded from the final model resulting from the forward selection.

Predictive performance of the prediction model Table 5 shows the predictive performance of several cut-off values for the predicted probability and the number of observed patients with progressive disease. Using cut-off values 0. The calibration plot of the prediction model is shown in the online supplementary file figure 2.

The prediction model showed a reliable calibration, predicting progressive disease in agreement with the observed progressive disease. The calibration plot showed that for predicted probabilities smaller than 0. For the probabilities higher than 0.

Predictive performance of several cut-off values for predicted probability of progressive disease The discriminative ability of the model was evaluated with an ROC curve see online supplementary file, figure 3 , showing an AUC of 0. The optimum cut-off value of the prediction model, as verified by the ROC curve, showed a sensitivity of 60 and a specificity of 85, corresponding to a cut-off value of 0.

Discussion This study is the first attempt to develop a clinical model to assess the chance for overall progressive disease in the short term in patients with SSc in order to guide clinical management. Our study shows that even in a cohort of patients with SSc not selected for disease duration or subtype, overall disease progression is frequently observed. By applying the model, the expected chance for progression could be increased from 37 to , depending on the chosen cut-off value, indicating that improved discrimination of patients is a reasonable possibility.

The current prediction model is not externally validated and should therefore be validated in other cohorts. However, internal validation showed that overfitting was not a problem, and results seem to be robust. A broad set of variables was available for evaluation of association with overall disease and its role in pulmonary involvement.

Friction rubs, proximal muscular weakness and VO2 max predicted as determined by CPET were the relevant predicting variables included in the model, after correction for age, gender and immunosuppressive treatment. This suggests that friction rubs, proximal muscular weakness and VO2 max are relatively sensitive variables in measuring overall progressive disease. Recently, a EUSTAR study concerning predictors of progressive disease has been published,4 identifying joint synovitis and tendon friction rubs as parameters independently associated with disease progression after 2 years of follow-up.

In our population, we did not find an association between synovitis and progressive disease however, friction rubs were significantly associated with progressive disease, confirming the relevance of this finding. As compared to this EUSTAR study, we used a different definition of progressive disease, generally identifying patients at an earlier disease stage. CPET evaluates patients during exercise, so it is likely to detect cardiopulmonary abnormalities not measurable at rest.

Different aspects of pulmonary involvement can be evaluated during CPET lung parenchymal damage as well as vascular abnormalities. Furthermore, it is highly reproducible, non-invasive and operator-independent. The role of the CPET in organ involvement screening is a relatively new finding.

They found that an impaired maximum oxygen uptake was present in 93 of the patients and independently associated with the severity of lung involvement. Our study confirmed the importance of CPET in identifying patients at risk for progressive disease in general, including progressive disease based on other parameters than pulmonary involvement or PAH.

Our study has several limitations which should be taken into account. First, no validated definition of progressive disease is available, and therefore overall progressive disease was defined as a combination of MIDs as used in randomised clinical trials in SSc. Whether this definition is a useful outcome parameter should be evaluated in future studies. We have chosen to define outcome parameters reflecting the different organ systems skin, lungs, kidneys , as well as parameters reflecting health in general weight loss, mortality, functional ability.

The cut-off values have been based on defined MIDs, as our intention is to select patients with a high risk for significant deterioration for more stringent annual follow-up. Second, the accuracy of our model is moderate. However, it is in line with other prediction models. Third, while other prediction models specifically have focused on patients with DcSSc, As a matter of interest, we did evaluate possible predictive factors in subpopulations with DcSSc and LcSSc, but no significantly strong predictors were identified.

In addition, since most patients with DcSSc had long-standing disease mean disease duration of 5. Including patients with L c SSc and patients with DcSSc with longer disease duration naturally decreased the overall percentage of patients with progressive disease in our cohort as patients presenting with early DcSSc have a different natural history.

We believe that this is explained by the fact that part of the patients with DcSSc had been treated successfully before the baseline visit and had stable low skin scores during the time frame under study. However, since our intention was to develop a prediction rule which can be used to guide clinical practice, for all patients with SSc currently in follow-up irrespective of disease duration or previous treatment, we explicitly chose to also include these patients.

Lastly, 38 of the patients were previously or currently treated with cyclophosphamide, MTX or autologous HSCT at baseline evaluation, which can have influenced our findings. Therefore, all logistic regression analyses were repeated including only patients who had not been treated before.

Multivariable logistic regression analyses in these patients identified VO2 max predicted as the only significant predictor data not shown. Since our aim was to develop a prediction rule which can be used to guide clinical practice, also in patients who have been treated before, we explicitly chose to develop our model based on a population including untreated patients and treated patients.

This study explored the possibility of prediction of progressive disease in the short term in a heterogeneous population with SSc. The advantages of our study are that the data were prospectively derived from a single centre cohort of patients with SSc. The number of missing values was very low. Since all patients fulfilling SSc classification criteria that visit in the healthcare programme are scheduled for a follow-up visit, independent of disease duration and subtype, the study population reflects the whole population present in a tertiary care centre and therefore the risk of selection bias is low.

As compared to other cohorts with SSc, the sociodemographic characteristics, disease severity and functional status of our cohort are comparable to those of other cohorts. Using the developed prediction model, the chance for progressive disease could be increased from 39 to , advocating annual stringent follow-up at least in patients with friction rubs, proximal muscle weakness and low maximum oxygen uptake at baseline. Future studies are needed to further optimise prediction of disease progression for the individual patient.

In addition, maximum oxygen uptake as measured by CPET was identified as a possible new biomarker for progressive disease in SSc. This finding should be replicated in different cohorts of patients with SSc.

While the symptoms of SSc vary for each person, it can be life-threatening depending on which parts of the body are affected and the extent of the disease. Patients with the diffuse form have more skin areas and organs involved and are the target population for clinical trials of disease-modifying interventions in SSc. The disease is more common in adults, with approximately 80,, people affected in the US.

Currently, there are no approved treatments specific to SSc. Current therapies for this disease include mainly drugs that suppress the immune system, are limited in efficacy and may present toxicities. New treatments will be critical to help reduce the symptoms of SSc and prevent further damage to the body. EHP is developing drug product candidates from its portfolio of patented cannabinoid derivatives, one derived from cannabidiol CBD for multiple sclerosis and systemic sclerosis EHP Both receptors are therapeutic targets for SSc.

Emerald Health Pharmaceuticals is developing product candidates derived from cannabinoids for the treatment of central nervous system CNS , autoimmune, fibrotic and other diseases. The Company has two families of new chemical entities, derived from synthetic cannabidiol CBD and cannabigerol CBG , that it has chemically modified through rational drug design to affect validated receptors and pathways pertinent to targeted diseases.

Its first drug product candidate, EHP, has completed a Phase 1 clinical study and is entering Phase 2 studies focused on treating systemic sclerosis and multiple sclerosis. Its second product candidate, EHP, is in preclinical development and is focused on treating Huntington's disease and Parkinson's disease. For more information, visit www.

In addition, systemic sclerosis can overlap with other autoimmune rheumatic disorders—eg, sclerodermatomyositis tight skin and muscle weakness indistinguishable from autoimmune myositis and mixed connective tissue disease. The most common initial symptoms and signs of systemic sclerosis are Raynaud phenomenon and insidious swelling of the distal extremities with gradual thickening of the skin of the fingers.

Polyarthralgia is also prominent. GI disturbances eg, heartburn, dysphagia or respiratory complaints eg, dyspnea are occasionally the first manifestations. Swelling of the skin is usually symmetric and progresses to induration. It may be confined to the fingers sclerodactyly and hands, or it may affect most or all of the body.

The skin eventually becomes taut, shiny, and hypopigmented or hyperpigmented; the face becomes masklike; and telangiectases may appear on the fingers, chest, face, lips, and tongue. However, in some patients, skin can soften to variable degrees. Subcutaneous calcifications may develop, usually on the fingertips pulps and over bony eminences.

Digital ulcers are common, especially on the fingertips, overlying the finger joints, or over calcinotic nodules. Abnormal capillary and microvascular loops in the nails can be seen with an ophthalmoscope or dissecting microscope. This image shows shiny and thickened skin with effacement of normal markings secondary to tautness, called sclerodactyly. In this image, bound-down taut skin throughout the chest also extends over the shoulders bilaterally, leading to a loss of range of movement of the shoulders.

Polyarthralgias or mild arthritis can be prominent. Flexion contractures may develop in the fingers, wrists, and elbows. Friction rubs may develop over the joints, tendon sheaths, and large bursae. Esophageal dysfunction is the most frequent visceral disturbance and occurs in most patients. Dysphagia usually retrosternal usually develops first. Acid reflux can cause heartburn and stricture.

Barrett esophagus occurs in one third of patients and predisposes to complications eg, adenocarcinoma. Hypomotility of the small bowel causes bacterial overgrowth that can lead to malabsorption. Air may penetrate the damaged bowel wall and be visible on x-rays pneumatosis intestinalis.

Leakage of bowel contents into the peritoneal cavity can cause peritonitis. Distinctive wide-mouthed diverticula can develop in the colon. Lung involvement generally progresses indolently, with substantial individual variability, but is a common cause of death.

Lung fibrosis and interstitial lung disease are common and can impair gas exchange, leading to exertional dyspnea and restrictive disease with eventual respiratory failure. Acute alveolitis potentially responsive to therapy can develop. Esophageal dysfunction can lead to aspiration pneumonia. Pulmonary hypertension may develop, as can heart failure, both of which are poor prognostic findings.

Pericarditis with effusion or pleurisy can occur. Cardiac arrhythmias are common. Severe, often sudden renal disease scleroderma renal crisis may occur, most commonly in the first 4 to 5 years in patients who usually have diffuse scleroderma and the RNA polymerase III antibody. It is often heralded by sudden, severe hypertension with features of thrombotic microangiopathic hemolytic anemia.

It can also occur without acute hypertension or in systemic sclerosis sine scleroderma, and therefore clinical suspicion is required to make the diagnosis. Corticosteroid use is a risk factor for development of scleroderma renal crisis. Systemic sclerosis should be considered in patients with Raynaud phenomenon, typical musculoskeletal or skin manifestations, or unexplained dysphagia, malabsorption, pulmonary fibrosis, pulmonary hypertension, cardiomyopathies, or conduction disturbances.

Diagnosis of systemic sclerosis sine scleroderma should be considered in patients who have unexplained visceral findings eg, pulmonary hypertension. Diagnosis of systemic sclerosis can be obvious in patients with combinations of classic manifestations, such as Raynaud phenomenon with abnormal nail-fold capillary findings , dysphagia, and tight skin.

However, in some patients, the diagnosis cannot be made clinically, and confirmatory laboratory tests can increase the probability of disease but their absence does not exclude it. Rheumatoid factor is positive in one third of patients. Antibody to centromeric protein anticentromere antibody occurs in the serum of a high proportion of patients with limited disease.

Patients with generalized diffuse systemic sclerosis are more likely than those with limited disease to have anti-Scl topoisomerase I antibodies. RNA polymerase III is associated with generalized systemic sclerosis, scleroderma renal crisis, and cancer. U3 RNP fibrillarin antibody is also associated with diffuse disease. The most cost-effective way to test for antibodies is to test for ANA, anti-Scl, and anticentromere antibodies first; if results are negative, testing for other antibodies should be considered based on clinical manifestations.

Abnormal nail-fold capillaries eg, ectatic blood vessels, dropout areas on capillaroscopy examination eg, seen with an ophthalmoscope or dissecting microscope. These criteria are weighted, in some cases according to subcriteria, and added to generate a score. Scores above a certain threshold are classified as definite systemic sclerosis. If lung involvement is suspected, pulmonary function testing, chest CT, and echocardiography can begin to define its severity.

Acute alveolitis is often detected by high-resolution chest CT. Predictors of early mortality include male sex, late onset, diffuse disease, pulmonary arterial hypertension, and renal crisis 1. The course depends on the type of disease generalized vs limited and antibody profiling but can be unpredictable. Patients with diffuse skin disease tend to have a more aggressive clinical course and eventually develop visceral complications usually within the first 3 to 5 years , which, if severe, can lead to death.

Heart failure may be intractable. Ventricular ectopy, even if asymptomatic, increases the risk of sudden death. Patients with limited systemic sclerosis CREST syndrome may have disease that is nonprogressive for long periods; visceral changes eg, pulmonary hypertension caused by vascular disease of the lung, a peculiar form of biliary cirrhosis eventually develop, but the course is often remarkably benign.

No drug significantly influences the natural course of systemic sclerosis overall, but various drugs are of value in treating specific symptoms or organ systems. Corticosteroids may be helpful if there is overt myositis or mixed connective tissue disease but may predispose to renal crisis and thus are used only if necessary. Various immunosuppressants, including methotrexate , azathioprine , mycophenolate mofetil, and cyclophosphamide , may help pulmonary alveolitis.

Mycophenolate mofetil is effective for the treatment of interstitial lung disease 1 and is the standard of care in some specialized centers. Successful lung transplantation has been reported. Epoprostenol prostacyclin and bosentan may be helpful for pulmonary hypertension. Calcium channel blockers, such as long-acting oral nifedipine eg, 30 to mg a day , may help Raynaud phenomenon but may worsen gastric reflux.

Bosentan , sildenafil , tadalafil , and vardenafil are other alternatives for severe Raynaud phenomenon. Patients should dress warmly, wear mittens, and keep their head warm. IV infusions of prostaglandin E1 alprostadil or epoprostenol or sympathetic blockers can be used for digital ischemia. Reflux esophagitis is relieved by frequent small feedings, high-dose proton pump inhibitors, sleeping with the head of the bed elevated, and not lying supine within 3 hours of the last meal.
