Evaluation of limited hand mobility in systemic sclerosis patients by using "prayer sign" and "tabletop sign".

OBJECTIVES: To determine limited joint mobility (LJM) of the hand in patients with systemic sclerosis (SSc). METHODS: LJM was evaluated with "prayer sign" and "tabletop sign" tests. LJM staging was done by Rosenbloom classification method. LJM (+) and LJM (-) patients were compared in terms of demographic findings (gender, age and duration of disease), laboratory results (ESR, CRP, anti-nuclear antibody (ANA), anti-topoisomerase I and anti-centromere), and modified Rodnan skin score (mRss) results. RESULTS: In our study, a total of 217 patients, including 113 patients with a diagnosis of SSc, and 104 as a healthy control group with similar age and gender distribution to these patients, were included. A total of 113 (F=98, M=15) patients (limited cutaneous SSc (lcSSc=71), diffuse cutaneous SSc (dcSSc=42)) were included in this study and LJM positivity was found in 66.4% (lcSSc=38, dcSSc=37). A statistically significant difference was observed in between lcSSc and dcSSc patients according to the presence of LJM (p<0.001). There was a moderate positivity relationship between LJM and mRss (lcSSc r=0.449, p<0.001; dcSSc r=0.565, p<0.001). CONCLUSIONS: In our study, it was found that LJM staging correlated with mRss and dcSSc patients had more severe LJM findings than lcSSc. We conclude that "prayer sign" and "tabletop sign" tests used in hand evaluation in SSc patients have similar clinical results with mRss and can be simple bedside tests in daily practice. Key Points • This is the first study examining limited joint mobility (LJM) with "prayer sign" and "tabletop sign" tests in systemic sclerosis (SSc) patients. • "Prayer sign" and "tabletop sign" tests can be easily performed in daily practice. • We found Rosenbloom LJM staging correlated with modified Rodnan skin score. LJM of the hand can be a good prognostic indicator for early stage SSc patients.

Development and Assessment of Novel Lung Ultrasound Interpretation Criteria for the Detection of Interstitial Lung Disease in Systemic Sclerosis.

OBJECTIVE: Interstitial lung disease (ILD) is a frequent complication of systemic sclerosis (SSc), and ILD screening, characterization, and monitoring are important for therapeutic decision-making and prognostication. Lung ultrasonography (US) is a potential alternative imaging modality for ILD detection. In this study, our objective was to develop and test a novel lung US examination technique and interpretation criteria for detecting SSc-ILD. METHODS: Lung US acquisition was performed by collecting short US movies at 14 lung positions. Lung US interpretation criteria for SSc-ILD detection focused on visualized pleural changes. To assess the performance of our methodology for SSc-ILD detection, we prospectively enrolled SSc patients with high-resolution computed tomography (HRCT) imaging within 3 months of lung US. Lung US examinations were scored independently by 2 blinded readers (1 ultrasonographer and 1 nonultrasonographer). The sensitivity and specificity for SSc-ILD detection were assessed, and agreement was measured with Cohen's kappa statistic. RESULTS: To test the performance of our lung US acquisition technique and interpretation criteria, 20 SSc patients were evaluated by lung US (278 lung zones) and HRCT. HRCT confirmed ILD in 9 patients (45%). Lung US was positive for SSc-ILD in 11 patients (55%) with a sensitivity of 100% and specificity of 82% versus HRCT, with perfect agreement between the 2 readers (κ = 1). Analysis by individual lung zones found excellent agreement between readers, with 93.8% concordance and κ = 0.82. CONCLUSION: We developed a novel lung US examination technique and interpretation criteria that are highly sensitive and specific for SSc-ILD detection in an SSc cohort, affording perfect agreement between ultrasonographer and nonultrasonographer readers.

Ultrasound Detection of Calcinosis and Association With Ulnar Artery Occlusion in Patients With Systemic Sclerosis.

OBJECTIVE: To investigate the ability of ultrasound (US) compared to radiographs to detect calcinosis in hands/wrists of patients with systemic sclerosis (SSc), and to assess US markers of pathologic perfusion. METHODS: Patients with SSc were evaluated for calcinosis in the hands/wrists by radiograph and US. The presence or absence of calcinosis was recorded by patient, hand, and anatomic zone; sensitivity and specificity for calcinosis detection by US versus radiographs was determined. Bilateral US vascular measurements of ulnar artery occlusion (UAO) and finger pulp blood flow (FPBF) were obtained. For each hand, associations between markers of pathologic blood flow (UAO, FPBF, and a composite severity score of UAO and FPBF) and the presence of calcinosis were assessed using generalized estimating equations. RESULTS: Of 43 patients with SSc (19 diffuse, 24 limited), 39.5% had calcinosis on radiographs compared to 30.2% on US. Sensitivity and specificity for US, respectively, were 61% and 95% by zone, 78% and 98% by hand, and 76% and 100% by patient. UAO was seen in 30% and 28% of left and right hands, respectively; FPBF was absent in ≥1 digit of the left and right hands in 49% and 44%, respectively. UAO was associated with radiograph-identified calcinosis by hand (odds ratio [OR] 8.08 [95% confidence interval (95% CI) 2.45-26.60], P < 0.001), whereas FPBF and the composite severity score were not significant. UAO was associated with calcinosis even in the absence of digital ulcers (OR 33.00 [95% CI 3.39-321.09], P = 0.003). CONCLUSION: US was sensitive and highly specific in detecting calcinosis in SSc. UAO was strongly associated with radiograph-identified calcinosis.

Impact of concomitant obstructive sleep apnea on pulmonary involvement and main pulmonary artery diameter in adults with scleroderma.

PURPOSE: Pulmonary involvement is common in adults with scleroderma. The effect of concomitant obstructive sleep apnea (OSA) on risk for pulmonary hypertension in scleroderma is unknown. An enlarged main pulmonary artery diameter (mPAD) derived from chest computer tomography (CT) is a useful predictor of pulmonary hypertension. We addressed the effect of OSA on pulmonary involvement and enlarged mPAD in adults with scleroderma. METHODS: All participants underwent pulmonary function testing, carbon monoxide diffusion capacity, chest CT, and overnight sleep recording with home sleep apnea testing. OSA diagnosis was based on an apnea-hypopnea index (AHI) ≥ 15/h. Oxygen desaturation index (ODI) was also recorded. Scleroderma involvement of the lungs was defined as the Warrick score ≥ 7 based on the CT findings. Enlarged mPAD was defined as an mPAD ≥ 29 mm in men and ≥ 27 mm in women. RESULTS: After exclusions, 62 patients (58 women) were included. OSA was found among 20 (32%), 17/42 (38%) in the limited cutaneous type, and 3/20 (15%) in the diffuse cutaneous type (p = 0.08). Scleroderma involvement of the lungs was observed in 40 participants (65% in OSA vs 64% in no-OSA; n.s.). Enlarged mPAD was measured in 16 participants, 10 of 20 (50%) in the OSA group and 6 of 17 (14%) in the no-OSA group (p = 0.003). OSA was associated with enlarged mPAD (odds ratio 4.7, 95% confidence interval 1.1-20.9; p = 0.042) independent of age, body mass index, and pulmonary involvement. There was a linear relationship between mPAD and AHI (r = 0.37; p = 0.003) as well as ODI (r = 0.41; p < 0.001). CONCLUSIONS: In this cohort, OSA was associated with risk for pulmonary hypertension independent of pulmonary involvement. These findings suggest that assessing the effect of therapy for concomitant OSA in patients with scleroderma is warranted. TRIAL REGISTRATION: NCT02740569.

A case report, a case who developed limited cutaneous scleroderma and pulmonary hypertension 8 years after diagnosis of anti-centromere antibody-positive Sjögren syndrome.

A 52-year-old woman was diagnosed as having anti-centromere antibody (ACA)-positive primary Sjögren syndrome (pSS). Eight years later, she visited our hospital because she had developed dyspnoea. She was diagnosed as having pulmonary arterial hypertension (PAH) with pulmonary veno-occlusive disease on the basis of the results of right heart catheterisation, a severe decrease in diffusing capacity of the lung for carbon monoxide (DLCO, 17%) and desaturation (69%) after a 6-minute walk test. She was also diagnosed as having limited cutaneous systemic sclerosis (lcSSc) because she had developed finger sclerosis. The six-minute walk distance had improved by 54 m 3 months after commencing treatment with tadalafil. Clinicians should be alert to the possibility of patients with ACA-positive SS developing lcSSc and PAH during their clinical course.

Limited cutaneous systemic sclerosis with gangrene: an autopsy case.

We describe an autopsy case of a 75-year-old female with limited cutaneous systemic sclerosis (lcSSc) and gangrene due to macrovascular involvement. She was diagnosed with lcSSc complicated with pulmonary arterial hypertension and digital ulcers 9 years before admission. She had recurrent and refractory lower limb ulcers (LLUs), and died because of sepsis caused by gangrene infection. Autopsy findings revealed severely thickened arterial walls of the visceral organs, consistent with vascular involvement of SSc. Systemic vascular involvement in lcSSc may progress in patients with LLUs who harbour several risk factors for vascular involvement.

Expert Perspectives On Clinical Challenges: Expert Perspectives: Challenges in Scleroderma.

You are consulted to evaluate a 56-year-old woman with known Raynaud's phenomenon, finger swelling of several; months' duration, and new hypertension with a blood pressure of 160/100 mm/Hg. She also reports progressive shortness of breath. Physical examination reveals telangiectasias, sclerodactyly, and proximal skin sclerosis (thick shiny skin on the chest and upper arms), and bibasilar crackles are found on chest examination. Laboratory tests reveal evidence of microangiopathic hemolytic anemia, thrombocytopenia, and elevation of the serum creatinine level (previously normal), and chest computed tomography shows evidence of ground-glass opacification in both lower lung fields.

Clinical characteristics and outcomes of 566 Thais with systemic sclerosis: A cohort study.

BACKGROUND: Most Thai patients with systemic sclerosis (SSc) have diffuse cutaneous SSc (dcSSc) unlike most Caucasians and some Asians. A longitudinal cohort study among Thai dcSSc is needed. OBJECTIVES: We aimed to determine the overall clinical characteristics, define the clinical difference between limited cutaneous SSc (lcSSc) and dcSSc, and ascertain the mortality rate and the factors associated with mortality. METHOD: We conducted a cohort study including 566 Thai adult SSc patients between January 2013 and June 2019. Clinical difference between lcSSc and dcSSc was investigated using generalized estimating equations (GEE). RESULTS: Females presented more than males (356 vs 210 cases). The majority of cases were dcSSc (411; 72.6%). The median duration of disease at the time of pulmonary fibrosis (PF) detection was 2.5 years, pulmonary arterial hypertension 8.1 years, and renal crisis 4.1 years. By GEE analysis, dcSSc was significantly associated with salt-and-pepper skin, hand deformity, and every 1-point increase in modified Rodnan skin score (mRSS). A greater mortality risk was associated with age at onset >60 years (hazards ratio [HR] 5.5), a World Health Organization functional class (FC) III (HR 5.1), FC IV (HR 34.8), edematous skin (HR 11.4), early onset of PF (HR 1.7), each 5-point increase in the mRSS (HR 4.5), and ≥2 internal organ involvements (HR 10.1). CONCLUSION: dcSSc is a common SSc subset among Thais. PF was an early complication in SSc and earlier PF detection was associated with a poorer prognosis. Elderly onset, high FC, severe skin tightness, and multiple organ involvements were associated with a greater mortality risk.

Clinical and serological profile of systemic sclerosis in Tunisia: A retrospective observational study.

OBJECTIVE: The Prevalence of systemic sclerosis (SSc) and different clinical subsets varies across the world. Few data have been published on SSc patients in North Africa. Our objective was to describe a SSc cohort in south of Tunisia and to compare clinical findings, disease subsets and antibodies with other international SSc populations. METHODS: In this retrospective observational study, Folders of patients with SSc seen in the internal medicine section of the Hedi Chaker Hospital between 2000 and 2013 were retrospectively analyzed. The diagnosis of SSc was retained according to ACR/EULAR 2013 criteria. Patients were classified into diffuse cutaneous SSc and limited cutaneous SSc subsets. Comparison with other cohorts was made based on published information. RESULTS: A higher female: male ratio (8:1) and a higher diffuse subset prevalence (82%) was found in this Tunisian cohort comparing with others. We also found a lower prevalence of calcinosis and anticentromere antibodies. Within each subset, diffuse cutaneous and limited cutaneous scleroderma clinical findings were similar with other systemic sclerosis populations except for a very low prevalence in renal crisis and pulmonary hypertension. Our results indicate overlap syndrome defined as scleroderma associated with others connective tissue disorder's is a relatively common condition. CONCLUSION: With slight variations, perhaps due to genetic, environmental or referral factors, SSc in this cohort appears to be similar to that described in other part of the world.

Exploring the microcirculatory effects of an exercise programme including aerobic and resistance training in people with limited cutaneous systemic sclerosis.

PURPOSE OF THE STUDY: High intensity interval training (HIIT) is able to improve the endothelial-dependent microvascular function is people with limited cutaneous systemic sclerosis (lcSSc). Resistance training (RT) alone has shown significant improvements in the function of the vasculature; moreover, a combination of aerobic and RT have shown both in the past and recently to significantly improve the vascular function and the microcirculation. Therefore, the purpose of this study is to explore the effectiveness of a combined exercise protocol (aerobic and resistance training) on microvascular function in people with lcSSc. METHODS: Thirty-two lcSSc patients (66.5 ±â€¯12 years old) were randomly allocated in two groups (exercise and control group). The exercise group underwent a 12-week exercise programme twice per week. All patients performed the baseline, three- and six-month follow up measurements where microvascular function, transcutaneous oxygen tension (ΔTcpO2) and body composition were assessed. RESULTS: The time to peak endothelial-dependent reactivity was significantly improved (91 ±â€¯42 s, d = 1.06, p = 0.007) when compared to control group after the exercise intervention. Endothelial-independent function was also significantly improved (3.16 ±â€¯2, d = 1.17, p = 0.005) when compared to the control group. Baseline (5.71 ±â€¯4.4, p < 0.05)) and peak (15.4 ±â€¯7.5, p < 0.05) transcutaneous oxygen pressure were also significantly improved compared to the control group. CONCLUSIONS: Our results suggest that a combined exercise protocol (aerobic and RT) was effective in improving endothelial-dependent reactivity in people with lcSSc. The next step would be to explore its clinical- and cost- effectiveness. Therefore, we recommend a large, community-based intervention against standard pharmacotherapy only, which would assess these important factors and support a change in therapeutic protocols and guidelines for this clinical population.

Association of metabolites reflecting type III and VI collagen formation with modified Rodnan skin score in systemic sclerosis - a cross-sectional study.

Objective: The objective was to investigate blood-based biomarkers of type I (PRO-C1), III (PRO-C3) and VI (PRO-C6) collagen formation in systemic sclerosis (SSc) patients and examine their correlation to modified Rodnan skin score (mRSS). Methods: Limited (lSSc, n = 76) and diffuse SSc (dSSc, n = 41) fulfilling the ACR/EULAR 1980 and 2013 classification criteria for SSc and asymptomatic controls (n = 9) were included. PRO-C1, PRO-C3 and PRO-C6 were measured in serum. Results: LSSc compared to dSSc were significantly older, had longer disease duration and lower mRSS. PRO-C3 was higher in early dSSc compared to early lSSc (mean [95 percentile], 27.4 [13.1-39.1] ng/mL vs 14.9 [8.2-28.8] ng/mL, p = 0.006). PRO-C6 levels were higher in early dSSc compared to early lSSc and late dSSc (early dSSc: 28.2 [10.4-92.3] ng/ml vs early lSSc: 11.0 [6.9-28.5] ng/ml; p = 0.006 and late dSSc: 12.6 [6.5-25.3] ng/mL, p = 0.04). No difference was observed with PRO-C1. PRO-C3 and PRO-C6 were moderately correlated with mRSS with R-partials of 0.36 (p < 0.001) and 0.29 (p = 0.002), respectively Conclusion: Measures of type III and VI collagen formation are potential objective biomarkers of fibrosis in systemic sclerosis. These biomarkers could be useful in monitoring the disease and efficacy of treatment.

Systemic Sclerosis at an Intensive Care Unit: A Case Series and Literature Review.

INTRODUCTION: Systemic sclerosis (SSc) is a multisystemic autoimmune disease. Few studies have focused on the outcomes of SSC patients who require intensive care unit (ICU) admission, largely due to the absence of protocols for the optimal management of this disease during an ICU stay. OBJECTIVES: This study aimed to describe the outcomes of a series of SSc patients admitted to the ICU at a single center in Cali, Colombia. METHODS: Case series of SSc patients admitted to the ICU were reviewed. The main outcome was ICU mortality. Statistical analysis was performed with measures of central tendency and proportions. RESULTS: All the patients (n = 14) were female and either middle-aged or elderly; 9 (64%) were diagnosed with diffuse cutaneous sclerosis, and the remaining 5 patients with limited cutaneous sclerosis. Some were readmitted; therefore, the total number of ICU admissions was 21. The principal causes of ICU admissions were non-SSc-related causes (n = 15 [71.4%]). The respiratory system was the most involved on ICU admissions. The ICU mortality rate was 43% (n = 6). CONCLUSIONS: The severity of the disease at ICU admission and comorbidity are independently associated with ICU-related mortality. Furthermore, the optimal management of SSc patients includes accurate detection of SSc-associated organ involvement. More studies involving this category of patients are needed to establish the best effective protocols.

Impact of EUSTAR standardized training on accuracy of modified Rodnan skin score in patients with systemic sclerosis.

OBJECTIVES: To investigate the impact of European Scleroderma Trials and Research (EUSTAR) standardized training on the accuracy of modified Rodnan skin score (mRSS) in patients with systemic sclerosis (SSc). METHODS: Eight SSc patients (four diffuse, four limited) and 10 physicians (4 fellows, 6 professors) were included. Gold-standard mRSS was performed by a senior instructor. Training comprised a video presentation and a live demonstration. Each physician performed mRSS with no clinical information in all patients: (a) before training; (b) after video session; and (c) after live demonstration. Primary outcome was the change in scoring accuracy, which was defined as the difference from the gold-standard skin score, as analyzed using a linear mixed model. RESULTS: Mean (standard deviation) difference from the gold-standard score in all measurements by participants before the training was 7.7 (9.5). Completion of training significantly enhanced mRSS accuracy (adjusted ß = -7.61; 95% CI: -11.91 to -3.32). This was largely attributable to the video presentation (adjusted ß = -5.47; -9.16 to -1.78), although the live demonstration was associated with numerical reduction in the difference from the gold-standard score (adjusted ß = -2.15; -5.84 to 1.55). Effect of training was prominent in fellows whereas professors showed an increase in the difference from gold-standard score after training (P value for interaction <0.001). The intraclass correlation coefficient for physician skin scores was acceptable. However, no significant change was observed after training. CONCLUSION: New EUSTAR standardized mRSS training significantly enhanced mRSS accuracy, especially in participant with less previous experience in skin scoring.

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.

Lymphedema secondary to limited cutaneous systemic sclerosis.

Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterised by vascular abnormalities, immune system activation and fibrosis. Lymphatic involvement in SSc was described more recently and starts in early stages. This report describes a 46-year-old patient who developed over the last 2 years asymmetric lymphedema in lower extremities. Compromise in lymphatic drainage was confirmed by lymphoscintigraphy. She also presented Raynaud's phenomenon, a scleroderma pattern in nailfold capillaroscopy, cutaneous thickening and anticentromere antibodies, which together resulted in a new diagnosis of limited cutaneous SSc. Treatment with methotrexate, prednisolone and lymphatic drainage resulted in lymphedema improvement. To our knowledge, this is the first case of grade 2 lymphedema in the setting of anticentromere-positive limited cutaneous SSc. We highlight the importance of considering rheumatic diseases in the differential diagnosis of lymphedema.

The effects of upper and lower limb exercise on the microvascular reactivity in limited cutaneous systemic sclerosis patients.

BACKGROUND: Aerobic exercise in general and high-intensity interval training (HIIT) specifically is known to improve vascular function in a range of clinical conditions. HIIT in particular has demonstrated improvements in clinical outcomes, in conditions that have a strong macroangiopathic component. Nevertheless, the effect of HIIT on microcirculation in systemic sclerosis (SSc) patients is yet to be investigated. Therefore, the purpose of the study was to compare the effects of two HIIT protocols (cycle and arm cranking) on the microcirculation of the digital area in SSc patients. METHODS: Thirty-four limited cutaneous SSc patients (65.3 ± 11.6 years old) were randomly allocated in three groups (cycling, arm cranking and control group). The exercise groups underwent a 12- week exercise program twice per week. All patients performed the baseline and post-exercise intervention measurements where physical fitness, functional ability, transcutaneous oxygen tension (ΔTcpO2), body composition and quality of life were assessed. Endothelial-dependent as well as -independent vasodilation were assessed in the middle and index fingers using LDF and incremental doses of acetylcholine (ACh) and sodium nitroprusside (SNP). Cutaneous flux data were expressed as cutaneous vascular conductance (CVC). RESULTS: Peak oxygen uptake increased in both exercise groups (p < 0.01, d = 1.36). ΔTcpO2 demonstrated an increase in the arm-cranking group only, with a large effect, but not found statistically significant,(p = 0.59, d = 0.93). Endothelial-dependent vasodilation improvement was greater in the arm-cranking (p < 0.05, d = 1.07) in comparison to other groups. Both exercise groups improved life satisfaction (p < 0.001) as well as reduced discomfort and pain due to Raynaud's phenomenon (p < 0.05). Arm cranking seems to be the preferred mode of exercise for study participants as compared to cycling (p < 0.05). No changes were observed in the body composition or the functional ability in both exercise groups. CONCLUSIONS: Our results suggest that arm cranking has the potential to improve the microvascular endothelial function in SSc patients. Also notably, our recommended training dose (e.g., a 12-week HIIT program, twice per week), appeared to be sufficient and tolerable for this population. Future research should focus on exploring the feasibility of a combined exercise such as aerobic and resistance training by assessing individual's experience and the quality of life in SSc patients.

Radiological pleuroparenchymal fibroelastosis associated to limited cutaneous systemic sclerosis: a case report.

BACKGROUND: Pleuroparenchymal fibroelastosis (PPFE) is a very rare interstitial lung disease (ILD) characterized by progressive fibrotic lesions of the visceral pleura and the sub-pleural parenchyma, affecting predominantly the upper lobes. PPFE may occur in different contextes like bone marrow or lung transplantations, but also in the context of telomeropathy with mutations of telomerase reverse transcriptase (TERT), telomerase RNA component (TERC) or regulator of telomere elongation helicase 1 (RTEL1) genes. PPFE-like lesions have recently been described in patients with connective tissue disease (CTD)-related ILD. We report here the first detailed case of PPFE associated to systemic sclerosis (SSc) in a woman free of telomeropathy mutations. CASE PRESENTATION: A caucasian 46 year old woman was followed for SSc in a limited form with anti-centromere Ab since 1998, and seen in 2008 for a routine visit. Her SSc was stable, and she had no respiratory signs. Pulmonary function tests showed an isolated decreased cTLCO at 55.9% (of predicted value). Cardiac ultrasonography was normal. Thoracic CT-scan showed upper lobes predominant mild and focal pleural and subpleural thickenings, suggestive of PPFE, with a slight worsening at 8 years of follow-up. She remained clinically stable. Biology only found a moderate and stable peripheral thrombocytopenia, and sequencing analysis did not find any mutations in TERT and TERC genes. CONCLUSIONS: ILD is frequent in SSc but isolated PPFE has never been described so far. In our case, PPFE is not related to telomeropathy, has indolent outcome and seems to have good prognosis. PPFE might be an extremely rare form of SSc-related ILD, although a fortuitous association remains possible.
