RESUMEN
OBJECTIVE: Recent studies have highlighted that systemic lupus erythematosus (SLE) is characterized by different types of symptoms: type 1 symptoms related to inflammation and disease activity and type 2 symptoms such as fatigue, anxiety-depression, and pain. Our aim was to investigate the relation between type 1 and type 2 symptoms, and their impact on health-related quality of life (HRQoL) in SLE. METHODS: A literature review was conducted about disease activity/type1 and type 2 symptoms. Articles in English published after 2000 were located on Medline via Pubmed. The articles chosen evaluated at least one type 2 symptom or HRQoL using a validated scale in adult patients. RESULTS: Overall, 182 articles were analyzed and 115 were retained including 21 randomized, controlled trials and corresponding to 36 831 patients. We found that in SLE, inflammatory activity/type 1 symptoms were mostly uncorrelated with type 2 symptoms and/or HRQoL. Several studies even showing an inverse relationship. No or weak correlation was observed in 85, 3% (92, 6%), 76, 7% (74, 4%) and 37, 5% (73, 1%) of studies (patients) for fatigue, anxiety-depression, and pain, respectively. For HRQoL, no or weak correlation was observed in 77, 5% of studies (88% of patients). CONCLUSION: Type 2 symptoms are poorly correlated with inflammatory activity/type 1 symptoms in SLE. Possible explanations and implications for clinical care and therapeutic evaluation are discussed.

OBJECTIVE: Giant cell arteritis (GCA) is the most common systemic vasculitis in individuals aged ≥50 years. Its course is marked by a high relapse rate requiring long-term glucocorticoid use with its inherent adverse effects. We aimed to identify factors associated with relapses or recurrences in GCA at diagnosis. METHODS: We reviewed the medical records of consecutive patients with GCA diagnosed between 2009 and 2019 and followed for at least 12 months. We recorded their characteristics at onset and during follow-up. Factors associated with relapses or recurrences were identified using multivariable analysis. RESULTS: We included 153 patients, among whom 68% were female with a median age of 73 (47-98) years and a median follow-up of 32 (12-142) months. Seventy-four patients (48.4%) had at least 1 relapse or recurrence. Headache and polymyalgia rheumatica were the most frequent manifestations of relapses. The first relapse occurred at a median time of 13 months after the diagnosis, with a median dose of 5.5 (0-25) mg/d of glucocorticoids.In multivariable analysis, patients with relapses or recurrences had a higher frequency of cough and scalp tenderness at diagnosis (20.3% vs 5.1%; odds ratio [OR], 4.73; 95% confidence interval [CI], 1.25-17.94; p = 0.022; and 41.9% vs 29.1%; OR, 2.4; 95% CI, 1.07-5.39; p = 0.034, respectively). Patients with diabetes mellitus at diagnosis had fewer relapses or recurrences during follow-up (5.4% vs 19%; OR, 0.24; 95% CI, 0.07-0.83; p = 0.024). CONCLUSIONS: Cough and scalp tenderness at diagnosis were associated with relapses or recurrences, whereas patients with diabetes experienced fewer relapses or recurrences.

OBJECTIVE: To assess the superiority of adipose tissue-derived stromal vascular fraction (AD-SVF) injection into the fingers vs placebo in reducing hand disability in systemic sclerosis (SSc) patients. METHODS: We performed a double-blind, multicentre, phase II trial from October 2015 to January 2018 in France. SSc patients with a Cochin Hand Function Scale (CHFS) ≥20/90 were randomized 1:1 to receive injection of AD-SVF or placebo. AD-SVF was obtained using the automated processing Celution 800/CRS system. The placebo was lactated Ringer's solution. The primary efficacy end point was the change of the CHFS score from baseline to 3 months. Secondary efficacy endpoints included the CHFS score at 6 months, hand function, vasculopathy, hand pain, skin fibrosis, sensitivity of the finger pulps, Scleroderma Health Assessment Questionnaire, patients and physician satisfaction, and safety. RESULTS: Forty patients were randomized. The AD-SVF and placebo groups were comparable for age, sex ratio, disease duration, skin fibrosis of the hands and main cause of hand disability. After 3 months' follow-up, hand function significantly improved in both groups with no between-group difference of CHFS (mean change of -9.2 [12.2] in the AD-SVF group vs -7.6 [13.2] in the placebo group). At 6 months, hand function improved in both groups. CONCLUSION: This study showed an improvement of hand function in both groups over time, with no superiority of the AD-SVF. Considering the limits of this trial, studies on a larger population of patients with homogeneous phenotype and hand handicap should be encouraged to accurately assess the benefit of AD-SVF therapy.

OBJECTIVE: Giant cell arteritis (GCA) is the most frequent vasculitis affecting adults aged > 50 years. Cardiac involvement in GCA is considered rare, and only a few cases of pericarditis have been reported. The aim of this study was to determine the characteristics and prognosis of GCA patients suffering from pericardial involvement at diagnosis. METHODS: We conducted a single-centre, retrospective chart review of patients with GCA in internal medicine departments (from 2000 to 2020). Patients were identified through a centralized hospital database. We retrospectively collected demographic, clinicobiological, histological, imaging, treatment and outcome data. Patients with pericardial effusion, defined as an effusion visible on the CT-scan performed at GCA diagnosis were compared to those without pericardial involvement. RESULTS: Among the 250 patients with GCA, 23 patients (9.2%) had pericardial effusion on CT-scan. The comparison between the groups revealed similar distribution of age, gender, cranial symptoms and ocular ischaemic complications. Patients with pericardial effusion had a higher frequency of weight loss. They also had lower haemoglobin levels and higher platelet levels (p = 0.006 and p = 0.002, respectively), and they more frequently had positive temporal artery biopsy. There were no differences concerning the treatment, relapses, follow-up duration or deaths. CONCLUSIONS: This case series sheds light on GCA as a cause of unexplained pericardial effusion or symptomatic pericarditis among adults aged > 50 years and elevated inflammatory biological markers. Fortunately, pericardial involvement is a benign GCA manifestation. In that context, the search for constitutional symptoms, cranial symptoms and associated signs of polymyalgia rheumatica is crucial for rapidly guiding GCA diagnosis.

INTRODUCTION: Although oesophageal motor disorders (OMDs) are frequent in systemic sclerosis (SSc), the frequency of associated endoscopic lesions is unknown. We aimed at assessing the presence of endoscopic lesions in SSc patients with OMD. The secondary objective was to identify the clinical and serological profile of such patients. METHODS: This retrospective study included SSc patients suffering from OMD diagnosed by oesophageal high-resolution manometry (OHRM) and with recent upper gastro-intestinal endoscopy (UGIE). Clinical data collected were age, gender, body mass index, SSc disease duration, tobacco, SSc cutaneous type, non-digestive SSc visceral disorders, oesophageal symptoms, serological profile (autoantibodies), proton pump inhibitor use, time between SSc diagnosis and UGIE. RESULTS: 53 selected patients from 210 SSc patients investigated by OHRM in our department were included. Among these patients, 25 (47.2%) had endoscopic lesions: 18 (34.6%) had oesophagitis and 7 (13.5%) had Barrett's oesophagus. The only two parameters significantly associated with endoscopic lesions were a shorter disease duration (6 vs. 11 years; p = .002) and a shorter delay between SSc diagnosis and UGIE (3 vs. 8.5 years; p = .002). No other clinical or biological parameters could help identify the patients at risk of endoscopic lesion. CONCLUSION: In our study, only a shorter disease duration and a shorter delay between SSc diagnosis and UGIE were significantly associated with the presence of endoscopic lesions in patients with OMD, but no other parameters were identified. This study highlights the need to perform UGIE in SSc patients with OMD whatever their clinical symptoms.

BACKGROUND: Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by fibrosis involving skin and multiple internal organs. Gastrointestinal manifestations occur with a prevalence of 75-90%, and severely impact the quality of life. Among them, gastric involvement may concern 50-80% of patients with gastroparesis. GPOEM has been recently proposed as effective treatment in refractory gastroparesis, reaching 80% of short-term efficacy with very low complication rate. This procedure has never been assessed in SSc patients; thus, we describe two cases of patient who benefited from GPOEM.Patients: There were 40 and 35 years old women suffering from SSc for 10 years, whom developed gastroparesis symptoms over the last year, with GCSI score of 3.4. The diagnosis was confirmed by gastric emptying scintigraphy showing increased half emptying time and residual percentages. After failure of medical therapy associating prokinetic agents and dietary measures, they were referred after multidisciplinary discussion for GPOEM procedure. The follow-up included GCSI score calculation, adverse events, and GES at 2 months. RESULTS: The procedures were uneventful, and the patients were discharged after 4 days and gradual refeeding. The post-operative GCSI 1 and 2.1, respectively, with both patients feeling significant clinical improvement, after a follow-up of 6 months. GES were also normalized in one patient. Despite improvement, one patient did not gain weight and had an additional jejunostomy. CONCLUSIONS: GPOEM may be an interesting therapeutic option in patient with SSc and severe gastroparesis after failure of classical treatment. This procedure could be proposed to patients after multidisciplinary discussion.

OBJECTIVE: The aims of this study were to describe and assess the vascular outcomes of patients with giant cell arteritis (GCA) presenting with only symptomatic isolated limb involvement (LI-GCA). METHODS: We recruited patients from 5 tertiary centers who were diagnosed with GCA based on histology or vasculitis demonstration on imaging and who presented with isolated symptomatic limb involvement at diagnosis. For each included patient, we randomly selected 3 control patients who satisfied the 5 criteria from the American College of Rheumatology at diagnosis. RESULTS: We included 27 LI-GCA patients and 81 control patients. Compared with the controls, the patients with LI-GCA were younger (p = 0.005), exhibited a more delayed diagnosis (p = 0.006), and had lower C-reactive protein levels (p = 0.001), but they did not show more cardiovascular risk factors. Glucocorticoid use (starting and tapering doses) and relapse rates did not differ in the 2 groups, but the patients with LI-GCA received longer treatment (p = 0.02). Cardiovascular complications occurred in 67% of the patients with LI-GCA versus 21% of the control patients (p < 0.0001), especially ischemic events (p < 0.0001) including stroke (p = 0.03) and myocardial infarction (p = 0.01). Vascular surgery was required in 44% of the patients with LI-GCA versus 2% of the controls (p < 0.0001). Excluding vascular surgery, the cumulative incidence of cardiovascular complications was higher in the patients with LI-GCA (log-rank test: p < 0.0001) than in the controls (hazard ratio, 5.73; 95% confidence interval, 2.94-11.28; p < 0.0001). CONCLUSIONS: Compared with the typical cranial form of GCA, LI-GCA has a worse cardiovascular-related prognosis. Further studies are required to determine the best management of these patients.

OBJECTIVE: The autologous stromal vascular fraction (SVF) from adipose tissue is an alternative to cultured adipose-derived stem cells for use in regenerative medicine and represents a promising therapy for vasculopathy and hand disability in systemic sclerosis (SSc). However, the bioactivity of autologous SVF is not documented in this disease context. This study aimed to compare the molecular and functional profiles of the SVF-based medicinal product obtained from SSc and healthy subjects. METHODS: Good manufacturing practice (GMP)-grade SVF from 24 patients with SSc and 12 healthy donors (HD) was analysed by flow cytometry to compare the distribution of the CD45- and CD45+ haematopoietic cell subsets. The ability of SVF to form a vascular network was assessed using Matrigel in vivo assay. The transcriptomic and secretory profiles of the SSc-SVF were assessed by RNA sequencing and multiplex analysis, respectively, and were compared with the HD-SVF. RESULTS: The distribution of the leucocyte, endothelial, stromal, pericyte and transitional cell subsets was similar for SSc-SVF and HD-SVF. SSc-SVF retained its vasculogenic capacity, but the density of neovessels formed in SVF-loaded Matrigel implanted in nude mice was slightly decreased compared with HD-SVF. SSc-SVF displayed a differential molecular signature reflecting deregulation of angiogenesis, endothelial activation and fibrosis. CONCLUSIONS: Our study provides the first evidence that SSc does not compromise the vascular repair capacity of SVF, supporting its use as an innovative autologous biotherapy. The characterisation of the specific SSc-SVF molecular profile provides new perspectives for delineating markers of the potency of SVF and its targets for the treatment of SSc.

Large-vessel involvement (LVI) in giant cell arteritis (GCA) includes different clinical and imaging patterns that are rarely described separately at diagnosis and whose specific cardiovascular outcomes are unknown. We conducted a nationwide retrospective study and included GCA patients with LVI demonstrated on imaging at diagnosis between 2007 and 2017. We analyzed the prognosis of three different imaging patterns of LVI present at diagnosis, with some of them overlapping but with the first one present in all patients: 1) inflammation of the aorta and/or its branches; 2) dilation of the aorta; and 3) stenosis of the aortic branches. A control group of GCA patients without LVI was constituted. We included 183 patients with LVI and 105 controls without LVI. Altogether, among the 183 patients who all showed inflammation of the aorta and/or its main branches, concomitant aortic dilation and large-vessel stenosis were observed in 27 (15%) and 55 (30%) patients, respectively. During the follow-up period, new cardiovascular events occurred in 49% and 11% of LVI patients and controls, respectively (pâ¯<â¯0.0001). Inflammation of the aorta and/or its branches (HR: 3.42 [2.09-5.83], pâ¯<â¯0.0001) and large-artery stenosis (HR: 2.75 [1.80-4.15], pâ¯<â¯0.0001) were independent predictive factors of new cardiovascular events. Conversely, the use of an immunosuppressant besides corticosteroids was a protective factor against new cardiovascular events (HR: 0.44 [0.29-0.66], pâ¯<â¯0.0001) and the development of aortic dilation (HR: 0.43 [0.23-0.77], pâ¯=â¯0.005). This study suggests different forms of cardiovascular events according to the initial imaging pattern of LVI.

OBJECTIVES: We aimed to assess the clinical significance of Krebs von den Lungen-6 (KL-6) in the diagnosis and severity of interstitial lung disease (ILD) in a French cohort of patients with systemic sclerosis (SSc). METHODS: Serum KL-6 concentrations were measured with chemiluminescent enzyme immunoassay (CLEIA) in 75 SSc patients. Patients were divided into two groups according to the presence of interstitial lung disease (SSc-ILD versus SSc-without ILD) on chest High-Resolution Computed Tomography. Pulmonary function tests, main manifestations and severity of the lung disease (Medsger's severity scale) were collected. RESULTS: KL-6 serum concentrations were significantly higher in SSc-ILD patients than in those without ILD (p < 10-4) and were inversely correlated with forced vital capacity, total lung capacity and diffuse lung capacity of carbon monoxide. Serum KL-6 level superior to 872 U/ml appeared as the optimal cut-off value associated with ILD. Patients with a restrictive pulmonary syndrome and dyspnoea had significant higher KL-6 serum concentrations. SSc patients with anti-topoisomerase 1 antibodies had higher KL-6 serum levels than patients with anti-centromere antibodies (p < 10- 4). ILD and anti-topoisomerase 1 antibodies were independent factors associated with KL-6 in multivariate analysis. Interestingly, KL-6 serum concentrations positively increased with the patient lung severity. CONCLUSIONS: Our study confirms that KL-6 is an accurate biomarker for the diagnosis of SSc-ILD in a French cohort of patients. High KL-6 levels should prompt physicians to assess ILD with pulmonary imaging and pulmonary functions tests. Prospective clinical studies are still required to determine whether levels of KL-6 might predict progression of ILD as well as its usefulness in the timing of therapeutic intervention.

OBJECTIVE: To assess the effect of sildenafil, a phosphodiesterase type 5 inhibitor, on digital ulcer (DU) healing in systemic sclerosis (SSc). METHODS: Randomised, placebo-controlled study in patients with SSc to assess the effect of sildenafil 20â mg or placebo, three times daily for 12â weeks, on ischaemic DU healing. The primary end point was the time to healing for each DU. Time to healing was compared between groups using Cox models for clustered data (two-sided tests, p=0.05). RESULTS: Intention-to-treat analysis involved 83 patients with a total of 192 DUs (89 in the sildenafil group and 103 in the placebo group). The HR for DU healing was 1.33 (0.88 to 2.00) (p=0.18) and 1.27 (0.85 to 1.89) (p=0.25) when adjusted for the number of DUs at entry, in favour of sildenafil. In the per protocol population, the HRs were 1.49 (0.98 to 2.28) (p=0.06) and 1.43 (0.93 to 2.19) p=0.10. The mean number of DUs per patient was lower in the sildenafil group compared with the placebo group at week (W) 8 (1.23±1.61 vs 1.79±2.40 p=0.04) and W12 (0.86±1.62 vs 1.51±2.68, p=0.01) resulting from a greater healing rate (p=0.01 at W8 and p=0.03 at W12). CONCLUSIONS: The primary end point was not reached in intention-to-treat, partly because of an unexpectedly high healing rate in the placebo group. We found a significant decrease in the number of DUs in favour of sildenafil compared with placebo at W8 and W12, confirming a sildenafil benefit. TRIAL REGISTRATION NUMBER: NCT01295736.

OBJECTIVE: Impaired hand function greatly contributes to disability and reduced quality of life in SSc patients. Autologous adipose-derived stromal vascular fraction (ADSVF) is recognized as an easily accessible source of regenerative cells. We reported positive 6-month safety and efficacy results from an open-label clinical trial assessing s.c. injection of autologous ADSVF into the fingers in SSc patients. The objective of this report is to describe the effects at 12 months. METHODS: Twelve females, mean age 54.5 years (s.d. 10.3), were assessed 1 year after ADSVF injection. Patients were eligible if they had a Cochin Hand Function Scale score >20/90. ADSVF was obtained from lipoaspirate using an automated processing system and subsequently injected into the s.c. tissue of each finger in contact with neurovascular pedicles in a one-time procedure. Endpoints were changes in hand disability and skin fibrosis, vascular manifestations, pain and quality of life at the 12 month follow-up. During the visit, patients estimated the benefit of the procedure with a specific self-completed questionnaire. RESULTS: A significant decrease from baseline of 51.3% (P < 0.001) for Cochin Hand Function Scale score, 63.2% (P < 0.001) for RP severity and 46.8% (P = 0.001) for quality of life (Scleroderma Health Assessment Questionnaire) was observed. A significant improvement of finger oedema, skin sclerosis, motion and strength of the hands and of the vascular suppression score was also noted. The reduction in hand pain approached statistical significance (P = 0.052). The questionnaire revealed a benefit in daily activities, housework and social activities. CONCLUSION: ADSVF injection is a promising therapy and appears to have benefits that extend for at least 1 year.

OBJECTIVES: In systemic sclerosis (SSc), esophageal and anorectal involvements are frequent and often associated with each other. In clinical practice, esophageal explorations are often prescribed, while anorectal explorations are rarely proposed and therefore, under-recognised. However, it is well documented in the literature that early detection of anorectal dysfunction could delay and/or prevent the onset of symptoms such as fecal incontinence (FI). The main objective was the systematic evaluation and detection of esophageal and anorectal involvements in SSc patients. METHODS: In this monocentric retrospective study, all patients with SSc addressed in the Department of Functional Digestive Explorations, North Hospital, Marseille for esophageal and anorectal explorations were included. Self-Questionnaires, evaluating the symptoms and quality of life, were filled by patients during their visit. Explorations were performed on the same day: high resolution esophageal manometry (EHRM), 3 Dimensional high resolution anorectal manometry (3DHRARM) and endo anal sonography (EUS). RESULTS: 44 patients (41 women), mean age 59.8±12 years, were included. With regard to the symptoms, 45.5% of patients had gastro-esophageal reflux disease (GERD), 66.9% dysphagia, 65.9% constipation and 77.3% FI. The incidence of esophageal dismotility was 65.9%, anorectal and both upper and lower dysfunction were 43.2%. More than 89% patients with abnormal explorations (EHRM, 3DHRARM or both) were symptomatic. Duration of SSc and altered quality of life was correlated with the severity of digestive involvement. CONCLUSIONS: Anorectal dysfunction appears to be closely linked to esophageal involvement in SSc. Their routine screening is undoubtedly essential to limit the occurrence of severe symptoms such as FI.

BACKGROUND: In patients with systemic sclerosis (scleroderma, SSc), impaired hand function greatly contributes to disability and reduced quality of life, and is insufficiently relieved by currently available therapies. Adipose tissue-derived stromal vascular fraction (SVF) is increasingly recognised as an easily accessible source of regenerative cells with therapeutic potential in ischaemic or autoimmune diseases. We aimed to measure for the first time the safety, tolerability and potential efficacy of autologous SVF cells local injections in patients with SSc with hand disability. METHODS: We did an open-label, single arm, at one study site with 6-month follow-up among 12 female SSc patients with Cochin Hand Function Scale score >20/90. Autologous SVF was obtained from lipoaspirates, using an automated processing system, and subsequently injected into the subcutaneous tissue of each finger in contact with neurovascular pedicles. Primary outcome was the number and the severity of adverse events related to SVF-based therapy. Secondary endpoints were changes in hand disability and fibrosis, vascular manifestations, pain and quality of life from baseline to 2 and 6â months after cell therapy. FINDINGS: All enrolled patients had surgery, and there were no dropouts or patients lost to follow-up. No severe adverse events occurred during the procedure and follow-up. Four minor adverse events were reported and resolved spontaneously. A significant improvement in hand disability and pain, Raynaud's phenomenon, finger oedema and quality of life was observed. INTERPRETATION: This study outlines the safety of the autologous SVF cells injection in the hands of patients with SSc. Preliminary assessments at 6â months suggest potential efficacy needing confirmation in a randomised placebo-controlled trial on a larger population.

OBJECTIVES: Although the last international guidelines for aPL recommended determination of IgA aCL and anti-ß2glycoprotein I (aß2GPI) antibodies for the evaluation of APS in the absence of conventional IgG or IgM aCL and aß2GPI antibodies, the clinical value of these antibodies remains controversial. We evaluated the clinical utility of IgA aPL and of the determination of target domains of aß2GPI IgA antibodies. METHODS: A retrospective analysis was performed on sera from 439 patients referred for routine detection of aPL IgA by in-house ELISA. Sera positive for aß2GPI IgA were subsequently tested for aß2GPI domain 1 (D1) and domain 4/5 (D4/5) antibodies using ELISAs. RESULTS: The prevalence of aß2GPI IgA antibodies was 16% in patients, significantly different from controls (1%, P < 0.0001). These antibodies were associated with clinical contexts related to APS as thrombosis (28.6% vs. 15%, P = 0.009) and SLE (42% vs. 15%, P < 0.0001). Interestingly, determination of their target domains revealed a significant association between aß2GPI IgA directed against D4/5 and SLE without thrombosis (66.7 vs. 16.7%, P = 0.002). In contrast, aCL IgA were not more prevalent in patients than in controls. CONCLUSION: Our study confirmed the interest of aß2GP1 IgA in the exploration of APS and suggests that identification of target domains of aß2GP1 IgA may be useful in the evaluation of thrombotic risk in SLE patients.

BACKGROUND: Systemic amyloidoses is a heterogeneous group of diseases either acquired or hereditary. Amyloidoses can involve the gastrointestinal tract and the nature of the precursor protein that forms the fibrils deposits should be identified to adjust the treatment and evaluate the prognosis. Lysozyme amyloidosis (ALys) is a rare, systemic non neuropathic hereditary amyloidosis with a heterogenous phenotype including gastrointestinal, renal and hepatic symptoms. CASE PRESENTATION: We report and describe symptoms and gastrointestinal tract involvement in a new family with hereditary lysozyme amyloidosis. Clinical manifestations and organ involvement of nine affected members of a new family with the p.Trp82Arg ALys variant were recorded. All affected individuals suffered with prevailing gastrointestinal symptoms leading to the diagnosis of ALys. 8/9 had non specific upper gastrointestinal symptoms and 3/9 had rectocolic inflammation evoking inflammatory bowel disease. No other organ involvement by amyloidosis was found. Histological examination revealed amyloid deposits in all cases and all carried the p.Trp82Arg ALys variant at a heterozygous state. CONCLUSION: Hereditary amyloidosis associated with the p.Trp82Arg lysozyme variant in this new family is predominantly associated with mild upper gastrointestinal tract involvement and in some cases with inflammatory bowel disease. Amyloidosis should be considered in atypical or treatment resistant, upper or lower chronic gastrointestinal symptoms. When associated with a familial history a lysozyme gene mutation must be searched.
