Abstract
OBJECTIVES The European Scleroderma Study Group (EScSG) activity index meets nearly all the OMERACT-standards of truth, discrimination and feasibility. The sensitivity to change remains to be attested. This study assesses sensitivity to change of the EScSG activity index in patients with early and severe diffuse cutaneous Systemic Sclerosis (dcSSc) treated with rituximab. METHODS 12-month follow-up (open-label study) of 14 consecutive patients with early dcSSc. Patients received an infusion of two times 1000 mg rituximab at month 0 and 6, together with 100 mg methylprednisolone. Clinical read outs (modified Rodnan skin score [mRSS], lung function and echocardiography) and EScSG activity index were performed at month 0, 3, 6 and 12. Mixed models analyses (MMA) were used to evaluate changes in parameters over time. RESULTS There was a clinically significant change in skin score with a mean (SD) mRSS of 24.8 (4.44) at baseline and 10.4 (3.12) at month 12 (MMA p<0.001). Also the EScSG activity index decreased significantly, with a mean (SD) of 4.3 (1.79) at baseline and 0.7 (0.83) at month 12 (MMA p<0.001). The estimated mean change of the EScSG activity index was -3.6 (95%CI -4.9; -2.4) over 12 months. Indices of internal organ involvement remained stable throughout the study. CONCLUSIONS A significant improvement of the EScSG activity index was observed, in line with the significant improvement of the mRSS and the stabilisation of internal organ involvement. To our knowledge, this is the first study to attest sensitivity to change of the EScSG activity index in the subset of 'early' dcSSc.

Abstract
Systemic scleroderma is a chronic, autoimmune disease of the connective tissue that involves skin, subcutaneous tissue, muscles and joints, as well as the internal organs: kidneys, lungs, heart. Depending on the extent it can occur as limited or diffuse clinical variant. In 60-80 % of patients with diffuse scleroderma, autopsy studies have shown pathologic changes in the kidneys. About half of the patients with renal involvement the clinical manifestation is limited to a moderate increase in serum creatinine, mild proteinuria, and moderate hypertension. The most serious complication remains sclerodermal renal crisis. It develops in 5-20 % of patients and is characterized by severe hypertension, acute kidney injury with oliguria, proteinuria and erythrocyturia, and microangiopathic hemolytic anemia with thrombocytopenia. In this article pathogenesis, risk factors, symptoms and treatment of scleroderma renal crisis have been reviewed.

Abstract
We report here a case of a 62-year-old Caucasian woman, suffering from diffuse cutaneous systemic sclerosis (SSc), who developed a tumoural calcinosis (TC) localised in the left side of the neck around the cervical spine that caused severe pain and motion impairment, without involvement of regional neurological structures. A review of the literature on this issue (based on PubMed database) allowed us to identify 35 previously described cases of TC in para-vertebral area in the course of SSc. The main characteristics of these patients have been summarised.

Abstract
OBJECTIVES To identify factors indicating exercise-induced oxygen desaturation during the 6-minute walk test (6MWT) in patients with diffuse systemic sclerosis (SSc) and initial interstitial lung disease (ILD). METHODS The study involved 121 consecutive adult anti-Scl 70 autoantibody-positive SSc patients with initial ILD, 93 of whom were followed up for five years. Before enrolment and then annually, the patients underwent high-resolution computed tomography (HRCT), functional lung tests, with carbon monoxide diffusion capacity of the lung (DLCO) and its components (alveolar-capillary membrane [Dm] and pulmonary blood volume [Vc]), the evaluation of dyspnea before and after the 6MWT using the Borg scale, and transthoracic echocardiography. A decrease in peripheral capillary oxygen saturation (SpO2) of ≥4% during the 6MWT was used to define desaturation, the appearance of which led to the patient being withdrawn from follow-up. RESULTS There were no significant differences in HRCT score during the follow-up, but 32 patients (35%) desaturated during the 6MWT, including 12 (37%) who experienced a severe decrease SpO2 to ≤88%, indicating a high risk of mortality. At baseline, there was no statistically significant difference in any considered clinical characteristics between the desaturating and non-desaturating patients but, at the time of desaturation, the desaturators had lower minimum SpO2% levels during the 6MWT (p<0.0001), and lower DLCO (p<0.0001) and Dm (p<0.0001). Comparison of the desaturators defined on the basis of a reduction in SpO2 to ≤88% and those defined on the basis of a decrease in SpO2 of ≥4% showed that, at baseline, the former had lower minimum SpO2% levels during 6MWT (p<0.001), lower DLCO (p=0.01), a lower DLCO/VA ratio (p=0.05), lower Dm (p<0.005) and Vc values (p<0.5), and higher RVsystP (p=0.01). At the time of desaturation, the desaturators' minimum SpO2 levels during the 6MWT correlated with their DLCO (r=0.78; p<0.001), Dm (r=0.65; p<0.01), Vc (r=0.52;p<0.05) and RV-systP values (r = -0.53; p<0.05). CONCLUSIONS Our data seem to confirm the close interdependence between pulmonary diffusion and oxygen desaturation during exercise. In SSc combined 6MWT, DLCO and its components may indicate patients at increased risk of developing pulmonary hypertension.

Abstract
OBJECTIVES Systemic sclerosis (SSc, scleroderma) is characterised by complex multi-organ pathogenesis, including gastrointestinal tract (GIT) disease that remains poorly characterised. Immunosuppression is commonly used to treat inflammatory manifestations of SSc, including the skin, lungs and joints. There is a paucity of data on the effects of immunosuppression on GIT disease in SSc. METHODS This case report and review of the literature presents two clinical cases in which interleukin-6 (IL-6) antagonism was used for early, diffuse skin disease. RESULTS In these two cases, IL-6 anta-gonism was associated with an exacerbation of GIT symptoms. CONCLUSIONS We postulate that IL-6 is important in the repair of GIT mucosa and further studies are warranted to better understand the effects of immunosuppression on SSc-GIT disease.

Abstract
Scleroderma is a chronic autoimmune disease of unknown cause characterized by fibrotic skin and multiple organs involvement, including the gastrointestinal tract. It occurs mainly in women between 35 and 65 years of age. It is classified as limited or diffuse based on the extent of skin involvement. Gastrointestinal dysmotility is observed in up to 90% of patients with a diffuse and limited scleroderma. It may involve any segment of the gastrointestinal tract from the esophagus to the anus and is related to collagen deposition at the level of enteric and vascular smooth muscle. Gastroparesis is a condition characterized by abnormal gastric motility, delay gastric emptying, in the absence of a mechanical obstruction to outflow. Gastric scintigraphy with radiolabeled solid food is the gold standard for the diagnosis of gastroparesis. Two cases of patients with systemic scleroderma and severe gastroparesis are presented in order to discuss the diagnostic and therapeutic approach, emphasizing the utility of gastric emptying scintigraphy.

Abstract
Less than 10% of the patients with systemic scleroderma develop renal crisis, i.e. acute renal failure and severe hypertension in most cases. Kidney biopsy shows hypertensive arteriolar changes. This complication was lethal until treatment with captopril was introduced in 1976. Since that time the survival of the patients has improved. If treatment is started early, further deteoriation of the kidney may be prevented.

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

Abstract
OBJECTIVES Knowledge about the nature and impact of symptoms faced by patients with systemic sclerosis (SSc) is needed to identify targets for research and treatment. The aim of this study was to assess and compare the frequency and impact on everyday activities of SSc symptoms among patients from five European countries. METHODS European patients with SSc were invited through announcements by patient associations to complete an online survey. The survey included items assessing the frequency of 40 SSc symptoms and the impact on daily activities, if present. Chi-square tests were utilised to assess the differences in frequency and impact of symptoms across countries. RESULTS In total, 537 patients were included from France (n=111), the Netherlands (n=229), Spain (n=61), Switzerland (n=50), and the United Kingdom (n=86). Symptoms experienced by ≥ 70% of patients in all countries were fatigue, Raynaud's phenomenon, joint pain, and muscle pain. Twenty symptoms were experienced by ≥ 50% of patients in all countries. Thirty symptoms had an impact on daily activities in ≥ 50% of patients who reported that the symptom was present in all countries. There were significant differences among countries in the prevalence of 17 out of 40 symptoms. Furthermore, in 24 out of 40 symptoms significant differences in the proportion of patients reporting impact of a specific symptom on everyday activities were observed. CONCLUSIONS European patients with SSc experience a broad range of symptoms that have an impact on everyday activities. International research initiatives should target common SSc symptoms cooperatively. Further research is needed to better understand the differences in SSc symptoms among countries.

Abstract
OBJECTIVES To compare a cohort of patients with systemic sclerosis sine scleroderma (ssSSc) vs. patients with limited cutaneous systemic sclerosis (lcSSc). METHODS Forty-five patients with ssSSc and 186 patients with lcSSc were investigated. Demographic, clinical and immunologic features and survival were compared. RESULTS There were no significant differences between ssSSc and lcSSc in gender, age at onset and interval between onset and diagnosis. ssSSc patients fulfilled the ACR criteria for SSc less than lcSSc patients (13%/77%, p<0.0001). There were no significant differences in articular involvement, myopathy, tendon friction rubs and gastrointestinal, pulmonary, cardiac and renal involvements. There was a trend to higher prevalence of pulmonary arterial hypertension (PAH) in ssSSc patients (29%/19%) but not reach significant difference. The prevalence of antinuclear and anticentromere antibodies and slow capilaroscopic pattern was similar. Sicca syndrome (13%/30%; p=0.024), digital ulcers (16%/50%; p<0.0001), calcinosis (11%/26%; p=0.047) and acroosteolysis (0% /10%; p=0.028) were more frequently in lcSSc. Survival at 5, 10, and 15 yr was not different in ssSSc and lcSSc patients (100%/98%, 100%/98%, and 92%/89%, respectively). CONCLUSIONS ssSSc and lcSSc patients share demographic, clinical and immunologic features. Survival is also similar in both groups. Differences are mainly due to peripheral vascular manifestations. However, despite great similarities, we believe that ssSSc patients should be considered as a different subset in order to avoid misdiagnosis. ssSSc patients should be truly differentiated from early SSc using sensitive and specific studies looking for any asymptomatic organ involvement.

Abstract
OBJECTIVES We sought to examine the relationship between measures of ILD severity and PH in patients with SSc. METHODS We identified 55 subjects from 12 PHAROS sites with RHC-proven PH and HRCT evidence of ILD. Subjects with PH due to left heart disease were excluded. Baseline HRCT scans were scored by a standardised system that graded severity of ILD. Summary statistics were generated for baseline characteristics. Spearman correlation and linear regression were used to examine relationships between ILD and PH severity variables. RESULTS The majority of subjects were white women; nearly half had limited cutaneous SSc. Most subjects were New York Heart Association functional class II or III. Pulmonary function testing revealed moderate restriction (mean FVC 64.3 ± 17.2% predicted) with severe reduction in diffusing capacity (mean DLco 34.2 ± 13.3% predicted). RHC demonstrated mild to moderate PH (mean PAP 35 ± 9 mmHg, mean PVR 5.1 ± 3.7 WU). There was no correlation between severity of ILD (by either HRCT or PFT) and cardiac haemodynamic parameters of PH. CONCLUSIONS No association between severity of ILD and cardiac haemodynamic profiles were identified in this cohort. We believe this underscores the complex nature of PH and ILD in individuals with SSc. We do suspect that some individuals with SSc-ILD will also have concomitant pulmonary vascular disease but simple assessments to grade severity of ILD - by PFT or HRCT estimates of ILD extent - are likely not enough to reliably distinguish between PAH versus PH-ILD. Further research into how to distinguish and manage these subsets is warranted.

Abstract
OBJECTIVES To evaluate endothelial function and vascular stiffness in large, medium, small and microcirculatory blood vessels in very early diffuse systemic sclerosis (SSc). METHODS We studied consecutive early diffuse SSc patients, defined as <2 years from first SSc symptom who did not have a prior cardiovascular event. Age, gender and race-matched controls were recruited. All underwent assessment of aortic pulse wave velocity (PWV), carotid intima-media thickness (IMT) brachial flow-mediated dilation (FMD), digital peripheral artery tonometer (EndoPAT) assessment and laser speckle contrast imaging (LSCI). RESULTS Fifteen early diffuse SSc and controls were evaluated. The average age was 49 years, 63% were female and 93% were Caucasian. There were no differences in body mass index, hypertension, diabetes or hyperlipidaemia between controls and SSc patients. Mean SSc disease duration was 1.3 years. In the large central vessels, there was no difference in aortic PWV (p=0.71) or carotid IMT (p=0.92) between SSc patients and controls. Similarly, there was no difference in endothelial dysfunction with brachial artery FMD after ischaemia (p=0.55) and nitroglycerin administration (p=0.74). There were significantly lower values for digital EndoPAT measures (p=0.0001) in SSc patients. LSCI revealed a distinct pattern of microcirculatory abnormalities in response to ischaemia in SSc patients compared to controls. Imaging demonstrated a blunted microcirculatory hyperaemia of the hand with greater subsequent response to nitroglycerin. CONCLUSIONS These findings suggest that the earliest endothelial changes occur in smaller arterioles and microvascular beds, but not in medium or macrovascular beds, in early diffuse SSc.

Abstract
OBJECTIVES We aimed to assess the long-term safety and tolerability of imatinib in diffuse cutaneous systemic sclerosis (dcSSc). METHODS In this open-label, single-arm, extension-phase clinical trial, patients continued imatinib for 24 months following 12 months of initial treatment. RESULTS Seventeen patients were enrolled. Forty of 92 adverse events (AE) and 0/6 serious (S) AEs were possibly related to medication. The MRSS decreased from a median of 21 to 16, (p=0.002). CONCLUSIONS This study demonstrates long-term safety and tolerability of imatinib in a substantial proportion of patients with dcSSc. This is important in evaluating the relevance of this therapy in a chronic disease such as SSc.

Abstract
Autologous stem cell transplantation (SCT) is increasingly used to treat autoimmune diseases (AD), in particular systemic sclerosis (SSc). Secondary autoimmune diseases are a known complication after autologous stem cell transplantations for any cause. A 43-year-old man had received an autologous stem cell transplantation for an aggressive diffuse cutaneous SSc. After mobilisation with cyclophosphamide and Granulocyte-Colony-Stimulating Factor stem cells were CD34-selected. The patient received a conditioning regimen with cyclophosphamide and Antithymocyte globulin. He had an excellent response with the modified Rodnan Skin Score decreasing from 34 to 3. One year and 4 months after SCT mild erythrocyturia without acanthocytes and proteinuria were seen for the first time on routine urinalysis. During the following year erythrocyturia increased to 131 erythrocytes /μl and protein excretion to 628 mg/g creatinine. At that time, acanthocytes of 25% finally could be detected. Due to the clearly nephritic constellation in urinalysis a renal biopsy was performed, which revealed mild global and focal-segmental sclerosing and focal-segmental proliferative glomerulonephritis without any signs of a IgA-nephropathy. The result was compatible with a renal manifestation of a small-vessel vasculitis. During the following laboratory workup ANCA of a perinuclear pattern with specificity for myeloperoxidase in high titers could be detected. Therefore the diagnosis of a p-ANCA-positive glomerulonephritis was established. As treatment, the patient received Rituximab, which turned out to be effective. We provide the first report of a patient who developed a p-ANCA-associated vasculitis after autologous stem cell transplantation for an autoimmune disease, namely systemic sclerosis.

Clin Exp Rheumatol 2014; 32:S-149-53.

Abstract
OBJECTIVES Hypoxia is a characteristic feature of systemic sclerosis (SSc).Transforming growth factor alpha (TGF-α) has an important role in excessive inflammation under hypoxic conditions. Since oesophageal dysmotility is one of the most common signs of SSc, the aim of this study was to explore the relation between TGF-α and oesophageal dysmotility in SSc. METHODS The study included 35 patients with SSc and 32 healthy controls matched for sex and age. Serum concentrations of TGF-α were measured using ELISA. Oesophageal motility was assessed by oesophageal scintigraphy. A multiple-swallow test was performed in the study population with 99mTc-DTPA. A region of interest over the entire oesophagus was defined and the retention index (RI) was calculated. RESULTS Statistically significant differences in serum concentration of TGF-α as well as of RI of 99mTc-DTPA were found between patients with SSc and healthy controls. A statistically significant correlation was found between serum concentrations of TGF-α and RIs of 99mTc-DTPA. This correlation was inverse, i.e. when serum concentrations of TGF-α increased, the RI of 99mTc-DTPA decreased (Spearman rho =-0361, p=0.033). CONCLUSIONS These results point to a possible relation between TGF-α and oesophageal dysmotility in SSc. Although the results do not explain the exact role of this cytokine in the pathogenesis of esophageal changes, the finding of inverse correlation between TGF-α and oesophageal dysmotility is intriguing and requires further investigation.

Abstract
OBJECTIVES To analyse the correlation between the number of joint-contractures and other major clinical findings in a follow-up study of 131 patients with systemic sclerosis (SSc). METHODS The range of motion of joints (ROM), HAQ-DI, and the major clinical characteristics were assessed. RESULTS A high frequency of contractures (ROM<75% of the normal) were present at baseline in small joints of the hand (82%), wrists (75%), and shoulders (50%). ROM of the dominant side hand was significantly more decreased compared to the non-dominant side. The number of the upper extremity contractures correlated positively with ESR (p<0.01), CRP (p<0.01), HAQ-DI (p<0.01), and negatively with forced vital capacity (FVC) (p<0.05). The number of contractures was not significantly different in cases with early (≤ 4 years) and late disease duration in both the limited and diffuse subgroups. During the three-year follow-up period, an increase in the number of joint contractures (ROM<75%) was associated with an increase of ESR, modified Rodnan's skin score, and the European Scleroderma Study Group Activity Index by multiple linear regression analysis. Univariate analysis over a six-year period demonstrated poor outcome in patients with more than ten contractures, or more than four contractures of unilateral hand-joints. CONCLUSIONS Contractures predominantly develop during the early years following disease onset in both SSc subgroups. Inflammation and skin-involvement are significant contributing factors for the development of contractures. The dominant hand may be more pronouncedly impaired compared to the non-dominant side. A high number of joint-contractures might be an unfavourable prognostic factor in SSc.

Abstract
Interstitial lung disease is the most common complication and cause of death among patients with scleroderma. Scleroderma-related interstitial lung disease has usually been treated with cyclophosphamide; however, its effect was evaluated to be modest and long-term administration of this drug is associated with adverse effects. Herein, we report our clinical experience of administering pirfenidone, which is an antifibrotic agent, in five patients with scleroderma-related interstitial lung disease. All patients demonstrated an increase in vital capacity.

Abstract
After immunosuppressive-induced infections, interstitial lung disease (ILD) is one of the most serious pulmonary complications associated with connective tissue diseases (CTD). Although it is common for ILD to be diagnosed concurrent with or after CTD, some patients will present with ILD years prior to receiving a diagnosis of CTD. The clinical approach involves an examination of the extrathoracic symptoms (suggestive of CTD) and the evaluation of respiratory disability. Nonspecific interstitial pneumonia is the most common histological finding in patients with CTD. The management of patients with CTD-associated ILD is optimized by multidisciplinary collaboration. ILD-CTD are treated through anti-inflammatory medication, immunosuppressants and biological agents.

Abstract
BACKGROUND Heart involvement confers a poor prognosis in patients affected by systemic sclerosis (SSc). Nevertheless, the prevalence of heart involvement in these patients is not fully known. In this study we analyzed the most frequent manifestations of heart involvement at rest in a cohort of patients with SSc, comparing their prevalence in patients with the limited form (lcSSc) and in patients with the diffuse form (dcSSc) of the disease, taking also into account the duration of the disease. METHODS We thoroughly evaluated with electrocardiographic and echocardiographic examinations 174 patients affected by SSc who were followed at our hospital between 2001 and 2011. They were divided according to the disease subtype (dcSSc vs lcSSc) and information about the disease duration was available for 121 of them (calculated from the onset of the Raynaud's phenomenon). RESULTS Patients with dcSSc had a greater prevalence of heart involvement at rest when evaluated within 5 and 10 years after the onset of the Raynaud's phenomenon (p=0.0051 within 5 years and p=0.035 within 10 years). Indeed, patients with dcSSc had a greater prevalence of atrioventricular conduction abnormalities within 20 years after the onset of the Raynaud's phenomenon (p=0.03 within 10 years and p=0.04 within 20 years) and a greater prevalence of valvular abnormalities within 5 years (p=0.04). In dcSSc there was a greater prevalence of rhythm disturbances in patients with a disease duration ≤20 or >20 years (p=0.04 within 20 years and p=0.04 after 20 years), but not in those with a disease duration ≤5 and ≤10 years. Left ventricular hypertrophy had a greater prevalence in dcSSc after 20 years of disease duration (p=0.02). CONCLUSIONS Cardiac manifestation occurs earlier and more frequently in patients affected by dcSSc than in patients with lcSSc.

Abstract
Systemic and chronic diseases frequently affect function of many organs and systems, not only those from which they derive. The hand is a very complicated structure in the human body and its normal activity is related to undisturbed function of many factors. Therefore, the hand is frequently exposed to harmful effects of systemic diseases. The article reports on disorders and functional disturbances of the hand that, more frequently than in an average population, accompany selected systemic diseases: rheumatoid arthritis, gout, and scleroderma. Hand diseases related to diabetes are a subject of a separate paper. This study reviews typical disorders involving hand structures: joints, tendons and nerves. Their prevention and management is described.

Subclinical myocardial inflammation and diffuse fibrosis are common in systemic sclerosis--a clinical study using myocardial T1-mapping and extracellular volume quantification. J Cardiovasc Magn Reson 2014; 16:21.

Abstract
BACKGROUND Systemic sclerosis (SSc) is characterised by multi-organ tissue fibrosis including the myocardium. Diffuse myocardial fibrosis can be detected non-invasively by T1 and extracellular volume (ECV) quantification, while focal myocardial inflammation and fibrosis may be detected by T2-weighted and late gadolinium enhancement (LGE), respectively, using cardiovascular magnetic resonance (CMR). We hypothesised that multiparametric CMR can detect subclinical myocardial involvement in patients with SSc. METHODS 19 SSc patients (18 female, mean age 55 ± 10 years) and 20 controls (19 female, mean age 56 ± 8 years) without overt cardiovascular disease underwent CMR at 1.5T, including cine, tagging, T1-mapping, T2-weighted, LGE imaging and ECV quantification. RESULTS Focal fibrosis on LGE was found in 10 SSc patients (53%) but none of controls. SSc patients also had areas of myocardial oedema on T2-weighted imaging (median 13 vs. 0% in controls). SSc patients had significantly higher native myocardial T1 values (1007 ± 29 vs. 958 ± 20 ms, p < 0.001), larger areas of myocardial involvement by native T1 >990 ms (median 52 vs. 3% in controls) and expansion of ECV (35.4 ± 4.8 vs. 27.6 ± 2.5%, p < 0.001), likely representing a combination of low-grade inflammation and diffuse myocardial fibrosis. Regardless of any regional fibrosis, native T1 and ECV were significantly elevated in SSc and correlated with disease activity and severity. Although biventricular size and global function were preserved, there was impairment in the peak systolic circumferential strain (-16.8 ± 1.6 vs. -18.6 ± 1.0, p < 0.001) and peak diastolic strain rate (83 ± 26 vs. 114 ± 16 s-1, p < 0.001) in SSc, which inversely correlated with diffuse myocardial fibrosis indices. CONCLUSIONS Cardiac involvement is common in SSc even in the absence of cardiac symptoms, and includes chronic myocardial inflammation as well as focal and diffuse myocardial fibrosis. Myocardial abnormalities detected on CMR were associated with impaired strain parameters, as well as disease activity and severity in SSc patients. CMR may be useful in future in the study of treatments aimed at preventing or reducing adverse myocardial processes in SSc.

Abstract
We herein report the case of a 72-year-old woman with diffuse cutaneous systemic sclerosis (SSc) complicated by antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis who exhibited honeycomb lung without volume loss. On admission, chest computed tomography (CT) revealed honeycomb lung without volume loss in addition to increased density of the partition walls. A renal biopsy revealed global sclerosis and cellular crescent formation. Mononeuritis multiple subsequently occurred, and steroid pulse therapy with cyclophosphamide was administered. Repeat chest CT showed that the honeycomb lung was unchanged; however, overall reduced density of the partition walls was observed. It is necessary to recognise that vasculitis may develop in SSc patients who exhibit honeycomb lung without volume loss.
