Whole phenotype of patients with systemic sclerosis and sicca manifestations: Comparison with sicca manifestations from other causes.

INTRODUCTION & OBJECTIVES: This study aimed to characterize the whole phenotype of Systemic sclerosis (SSc) patients with sicca symptoms, using major salivary glands Ultrasound (SGUS) parameters, minor salivary glands biopsies (mSGB) and clinical findings, and to compare these characteristics with those from patients with Sjogren's Disease (SjD), and patients with sicca manifestations from other causes. METHODS: Sixty SSc patients fulfilling the 2013 ACR/EULAR classification criteria and with subjective self-declared sicca symptoms were consecutively recruited and had SGUS and mSGB. Fifteen SSc patients without subjective sicca symptoms and 65 patients with sicca symptoms from other causes (including 37 SjD with no SSc). RESULTS: SSc patients with subjective sicca symptoms had frequent objective clinical (up to 83 %), histological (44 % of Focus score≥1/ mm2) and US anomalies (63 % of OMERACT ≥2). 53 % patients without subjective clinical complaint also had abnormal objective tests, suggesting the existence of a sub clinical involvement of salivary glands in SSc. SjD-SSc patients had more severe glandular involvement as compared to patients with isolated SjD and isolated Sicca-SSc patients (70%, 48,6 % and 38% of patients with OMERACT ≥2 respectively) suggesting additive impact of both diseases on glandular physiology and structure. CONCLUSION: SjD-SSc overlap have more severe sicca features as compared to isolated sicca-SSc and isolated SjD, suggesting a specific impact of SSc on salivary gland physiology. Further translational studies are needed to identify the underlying pathways that could serve as therapeutic targets.

"With Great Responsibility Comes Great Uncertainty".

BACKGROUND: Uncertainty is inherent in medicine, and trainees are particularly exposed to the adverse effects of uncertainty. Previous work suggested that junior residents seek to leverage the support of supervisors to regulate the uncertainty encountered in clinical placements. However, a broader conceptual framework addressing uncertainty experience, from the sources of uncertainty to residents' responses, is still needed. OBJECTIVE: To capture the spectrum of uncertainty experiences in medical residents, providing an integrative framework that considers the influence of specialties and training stages on their experience with clinical uncertainty. DESIGN: We used Hillen's uncertainty tolerance framework to conduct a thematic template analysis of individual and focus group interviews, identifying themes and subthemes reflecting residents' experience of clinical uncertainty. PARTICIPANTS: Medical residents from diverse medical specialty training programs, across five French medical schools. APPROACH: Qualitative study driven by an interpretivist research paradigm. RESULTS: Twenty residents from all years of medical residency and diverse medical specialties were interviewed during three focus groups and five individual interviews. They described managing treatments, making ethical decisions, and communicating uncertainty, as their major sources of uncertainty. We identified residents' delayed response to uncertainty as a key theme, fostering the development of experiential learnings. Prior clinical experience was a key determinant of uncertainty tolerance in medical residents. Entrusting residents with responsibilities in patient management promoted their perception of self-efficacy, although situations of loneliness resulted in stress and anxiety. CONCLUSION: Residents face significant uncertainty in managing treatments, ethical decisions, and communication due to limited clinical experience and growing responsibilities. Scaffolding their responsibilities and clearly defining their roles can improve their comfort with uncertainty. To that extent, effective supervision and debriefing are crucial for managing emotional impacts and fostering reflection to learn from their uncertain experiences.

History of pre-eclampsia does not appear to be a risk factor for vascular phenotype in women with systemic sclerosis.

BACKGROUND: Vascular phenotype is associated with a poor prognosis in systemic sclerosis (SSc). The identification of its risk factors could facilitate its early detection. OBJECTIVES: To explore risk factors for a vascular phenotype of SSc, among them a history of pre-eclampsia. METHODS: This observational multicentre case-control study enrolled adult women fulfilling European Alliance of Associations for Rheumatology 2013 diagnosis criteria for SSc and having a pregnancy history≥6 months before SSc diagnosis in 14 French hospital-based recruiting centres from July 2020 to July 2022. Cases had specific vascular complications of SSc defined as history of digital ischaemic ulcers, pulmonary arterial hypertension, specific cardiac involvement or renal crisis. Women with SSc were included during their annual follow-up visit and filled in a self-administered questionnaire about pregnancy. A case report form was completed by their physician, reporting data on medical history, physical examination, clinical investigations and current medication. The main outcome was the presence/absence of a personal history of pre-eclampsia before SSc diagnosis, according to the validated pre-eclampsia questionnaire. RESULTS: 378 women were included: 129 cases with a vascular phenotype and 249 matched controls. A history of pre-eclampsia was reported in 5 (3.9%) cases and 12 (4.8%) controls and was not associated with a vascular phenotype (OR=0.96, 95% CI 0.28 to 3.34, p=0.9). Besides, Rodnan skin score and disease duration≥5 years were risk factors for vascular phenotype. CONCLUSIONS: In women with SSc and a pregnancy history≥6 months before SSc, a history of pre-eclampsia is not associated with a vascular phenotype.

Prognostic value and predictors of the alteration of the diffusing capacity of the lungs for carbon monoxide in systemic lupus erythematosus.

OBJECTIVES: Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by heterogeneous manifestations and severity, with frequent lung involvement. Among pulmonary function tests (PFT), the measure of the diffusing capacity of the lungs for carbon monoxide (DLCO) is a noninvasive and sensitive tool assessing pulmonary microcirculation. Asymptomatic and isolated DLCO alteration has been frequently reported in SLE, but its clinical relevance has not been established. METHODS: This retrospective study focused on 232 SLE patients fulfilling the 2019 EULAR/ACR classification criteria for SLE. Data were collected from the patient's medical record, including demographic, clinical, and immunological characteristics while DLCO was measured when performing PFT as part of routine patient follow-up. RESULTS: At the end of follow-up, DLCO alteration (<70% of predicted value) was measured at least once in 154 patients (66.4%), and was associated with a history of smoking as well as interstitial lung disease (ILD), but was also associated with renal and neurological involvement. History of smoking, detection of anti-nucleosome autoantibodies and clinical lymphadenopathy at diagnosis were independent predictors of DLCO alteration, while early cutaneous involvement with photosensitivity was a protective factor. DLCO alteration, at baseline or anytime during follow-up was predictive of admission in intensive care unit and/or of all-cause death, both mainly due to severe disease flares and premature cardiovascular complications. CONCLUSION: This study suggests a link between DLCO alteration and disease damage, potentially related to SLE vasculopathy, and prognostic value of DLCO on death or ICU admission in SLE.

Vacuoles, E1 enzyme, X-linked, autoinflammatory, and somatic syndrome in the intensive care unit: a case report.

BACKGROUND: Vacuoles, E1 enzyme, X-linked, autoinflammatory, and somatic syndrome is a newly discovered inflammatory disease affecting male subjects, for which few data exist in the literature. Here, we describe the case of a patient with known Sweet's syndrome admitted to the intensive care unit and for whom a vacuoles, E1 enzyme, X-linked, autoinflammatory, and somatic syndrome was diagnosed, allowing for appropriate treatment and the patient's discharge and recovery. CASE PRESENTATION: A 70-year-old male White patient was hospitalized in the intensive care unit following an intrahospital cardiac arrest. History started a year before with repeated deep vein thrombosis and episodes of skin eruption compatible with Sweet's syndrome. After a course of oral steroids, fever and inflammatory syndrome relapsed with onset of polychondritis, episcleritis along with neurological symptoms and pulmonary infiltrates. Intrahospital hypoxic cardiac arrest happened during patient's new investigations, and he was admitted in a critical state. During the intensive care unit stay, he presented with livedoid skin lesions on both feet. Vasculitis was not proven; however, cryoglobulinemia screening came back positive. Onset of pancytopenia was explored with a myelogram aspirate. It showed signs of dysmyelopoiesis and vacuoles in erythroid and myeloid precursors. Of note, new deep vein thrombosis developed, despite being treated with heparin leading to the diagnosis of heparin-induced thrombocytopenia. The course of symptoms were overlapping multiple entities, and so a multidisciplinary team discussion was implemented. Screening for UBA1-mutation in the blood came back positive, confirming the vacuoles, E1 enzyme, X-linked, autoinflammatory, and somatic syndrome. Corticosteroids and anti-IL1 infusion were started with satisfactory results supporting patient's discharge from intensive care unit to the internal medicine ward. CONCLUSIONS: Vacuoles, E1 enzyme, X-linked, autoinflammatory, and somatic syndrome should be suspected in male patients presenting with inflammatory symptoms, such as fever, skin eruption, chondritis, venous thromboembolism, and vacuoles in bone marrow precursors. Patients with undiagnosed vacuoles, E1 enzyme, X-linked, autoinflammatory, and somatic syndrome may present with organ failure requiring hospitalization in intensive care unit, where screening for UBA1 mutation should be performed when medical history is evocative. Multidisciplinary team involvement is highly recommended for patient management, notably to start appropriate immunosuppressive treatments.

Ultrasound Classification of Finger Pulp Blood Flow in Patients With Systemic Sclerosis: A Pilot Study.

OBJECTIVE: To define a semiquantitative classification of finger pulp blood flow (FPBF) and to evaluate whether this classification could be used to assess FPBF in healthy controls and in systemic sclerosis (SSc) patients. METHODS: Thirty controls and 86 SSc patients were consecutively included. A classification of FPBF including 5 grades (from grade 0 [no signal] to 4 [signal detected on the entire finger pulp, including the subepidermal vascular network]) was evaluated. This classification was explored in basal conditions and after hand baths in hot and cold water in controls. Its relevance was also assessed at room temperature in SSc patients. RESULTS: In controls, power Doppler ultrasonography (PDUS) of FPBF was improved after hot challenge (P = 0.024), whereas cold challenge decreased FPBF (P = 0.001). FPBF correlated with the vasodilation status assessed by the resistivity index of radial arteries (Spearman's correlation coefficient = -0.50, P = 0.0049). Grade 0 was more frequent in SSc patients than in controls (22.1% versus 3.3%; P < 0.05). In SSc patients, grade 0 was associated with severity markers of the digital vasculopathy such as digital ulcers (DUs) (current or past) (P < 0.05) or ulnar artery occlusion (P < 0.05). On the other hand, DUs were less frequent in patients with grade 4 (P < 0.05). A pathologic threshold of <2 (grade 0 or 1) was significantly associated with DUs (odds ratio 6.67 [95% confidence interval 2.31-19.21], P < 0.0001). CONCLUSION: PDUS allowed a semiquantitative evaluation of FBPF in SSc patients and controls. Further studies are warranted to validate these results in independent SSc populations and to compare PDUS to existing tools assessing digital blood flow.

Should we really include systemic sclerosis specific antibodies in the classification criteria of Sjogren's disease?

We have read with great interest the results from Marketos et al. regarding the positivity of specific systemic sclerosis auto-antibodies in patients with sicca symptoms. Based on complementary data from the literature, we rather believe scleroderma-associated antibodies should be considered either as a yellow flag for an association between scleroderma and Sjogren, or a potential undiagnosed scleroderma, rather than an isolated Sjogren's disease.

Sicca syndrome in systemic sclerosis: a narrative review on a neglected issue.

SSc is an auto-immune disease characterized by life-threatening manifestations such as lung fibrosis or pulmonary arterial hypertension. Symptoms with a detrimental impact on quality of life are also reported and sicca syndrome (xerostomia, xeropthalmia) is present in up to 80% of patients with SSc. Sicca syndrome can occur in the absence of overlap with Sjögren's disease and recent studies highlight that fibrosis of minor and major salivary glands, directly linked to the pathogenesis of SSc, could be a major contributor of xerostomia in SSc. This narrative review provides an overview of the clinical presentation, diagnostic strategies, management and future perspectives on sicca syndrome in patients with SSc.

Pregnancy outcomes in women with primary Sjögren's syndrome: an analysis of data from the multicentre, prospective, GR2 study.

BACKGROUND: Adverse pregnancy outcomes in women with primary Sjögren's syndrome have only been evaluated retrospectively using heterogeneous methods and with contradictory results. We aimed to describe adverse pregnancy, delivery, and birth outcome risks in pregnant women with primary Sjögren's syndrome compared with those of a matched general population in France, and to identify factors predictive of disease flares or adverse pregnancy outcomes. METHODS: We conducted a multicentre, prospective, cohort study in France using the GR2 (Groupe de Recherche sur la Grossesse et les Maladies Rares) registry. Women from the GR2 study were eligible if they had conceived before March, 2021, had primary Sjögren's syndrome according to the American College of Rheumatology and European Alliance of Associations for Rheumatology (EULAR) 2016 classification criteria, and had an ongoing pregnancy at 12 weeks of gestation. In women who entered in the registry with pregnancies before 18 weeks of gestation, we sought to identify factors associated with primary Sjögren's syndrome flare (≥3-point increase in EULAR Sjögren's Syndrome Disease Activity Index [ESSDAI] score) or adverse pregnancy outcomes (fetal or neonatal death, placental insufficiency leading to a preterm delivery [<37 weeks of gestation], or small-for-gestational-age birthweight). A matched controlled study compared adverse pregnancy, delivery, and birth outcome rates between pregnant women with primary Sjögren's syndrome from the GR2 registry and matched controls from the general population included in the last French perinatal survey (Enquête Nationale Périnatale 2016). FINDINGS: 1944 pregnancies were identified in the GR2 cohort, of which 106 pregnancies in 96 women with primary Sjögren's syndrome were included in this analysis. The median age at pregnancy onset was 33 years (IQR 31-36). 87 (83%) of 105 pregnancies (with ethnicity data) were in White women, 18 (17%) were in Black women; 92 (90%) of 102 had previous systemic activity (ESSDAI score of ≥1; data missing in four pregnancies), and 48 (45%) of 106 had systemic activity at inclusion. Of 93 pregnancies included at week 18 of gestation or earlier, primary Sjögren's syndrome flares occurred in 12 (13%). No baseline parameters were associated with primary Sjögren's syndrome flare. Four twin pregnancies and one medical termination were excluded from the adverse pregnancy outcome analysis; of the remaining 88, adverse pregnancy outcomes occurred in six (7%). Among pregnancies in women with data for antiphospholipid antibodies (n=55), antiphospholipid antibody positivity was more frequent among pregnancies with adverse outcomes (two [50%] of four pregnancies) compared with those without adverse outcomes (two [4%] of 51 pregnancies; p=0·023). Anti-RNP antibody positivity was also more frequent among pregnancies with adverse outcomes than those without, although this was not statistically significant. In the matched controlled study, adverse pregnancy outcomes occurred in nine (9%) of 105 pregnancies in women with primary Sjögren's syndrome and 28 (7%) of the 420 matched control pregnancies; adverse pregnancy outcomes were not significantly associated with primary Sjögren's syndrome (odds ratio 1·31, 95% CI 0·53-2·98; p=0·52). INTERPRETATION: Pregnancies in women with primary Sjögren's syndrome had very good prognoses for mothers and fetuses, with no overall increase in adverse pregnancy outcome risk compared with the general population. Women with antiphospholipid antibodies or anti-RNP antibodies require close monitoring, because these factors might be associated with a higher risk of adverse pregnancy outcomes.

Patient-reported outcomes and their relation with iron parameters in HFE haemochromatosis during maintenance therapy: A prospective cohort study.

BACKGROUND & AIMS: The standard of care for haemochromatosis is regular phlebotomy in order to maintain low ferritin levels. Many patients report fatigue or joint pain despite serum ferritin within the therapeutic targets. We evaluated Patient-Reported Outcomes, and their relation with iron parameters, in C282Y homozygous patients undergoing maintenance phlebotomy. METHODS: Patients were prospectively enrolled in a French referral care centre. At each phlebotomy, patients completed a numeric fatigue scale, a joint pain questionnaire and SF-36 Mental Component Score (MCS) and Physical Component Score (PCS). Haemoglobin, iron, TS and ferritin were collected concomitantly. RESULTS: About 701 visits were performed in 259 patients. The median fatigue score was 3/10; 171 (66%) patients reported joint pain. Age and worsening of joint pain were associated with fatigue (p < .0001 for both). Female gender (p < .037), age (p < .003), and a decrease of TS (p = .050) were associated with joint pain. Main features associated with PCS <50 were worsening of joint pain and age (p < .001 for both) and TS <20% (p < .02). CONCLUSIONS: Fatigue was independent from iron parameters. The main factor impacting quality of life was joint pain, which was more severe in patients with low TS values. Then, a more precise monitoring of TS should be proposed during haemochromatosis maintenance therapy; while less stringent monitoring of serum ferritin levels could be tested.

Sacroiliac joint in sarcoidosis on computed tomography: a monocentric retrospective study (SISTER).

Sacroiliitis and spondyloarthritis (SpA) have been associated to sarcoidosis. Sarcoidosis bone involvement of the sacral or iliac bones has been reported to mimic SpA. We aimed to evaluate the prevalence of structural sacroiliitis and structural changes of the sacroiliac joints (SIJ) in patients with sarcoidosis by abdominal-pelvic computed tomography (AP-CT). In this monocentric retrospective study, three blinded readers evaluated AP-CT that had already been performed on patients with sarcoidosis and classified them as normal, degenerative, or inflammatory. A consensus was reached for the divergent cases. Erosion, ankylosis, and sclerosis, classically associated with sacroiliitis, were noted. SpA was defined according to the ASAS 2009 classification criteria. We identified 217 patients with proven sarcoidosis who underwent AP-CT. Only three patients had sacroiliitis by CT and four had SpA, representing 1.38% and 1.85% of the patients, respectively. Degenerative SIJs represented 28.1% of patients and were significantly associated with age, at least one pregnancy, rural lifestyle, ankylosis, diffuse idiopathic skeletal hyperostosis, sclerosis, and the presence of osteophytes. Four patients had axial bone sarcoidosis. Sacroiliitis, SpA, and degenerative changes of the SIJ have been highlighted by AP-CT in patients with sarcoidosis. Osteoarthritis of the SIJ in sarcoidosis was associated with age, pregnancy, and rural lifestyle. Further studies are needed to assess the link between SpA and sarcoidosis.

Characterisation of a high-risk profile for maternal thrombotic and severe haemorrhagic complications in pregnant women with antiphospholipid syndrome in France (GR2): a multicentre, prospective, observational study.

BACKGROUND: Prospective data about the risks of thrombotic and severe haemorrhagic complications during pregnancy and post partum are unavailable for women with antiphospholipid syndrome. We aimed to assess thrombotic and haemorrhagic events in a prospective cohort of pregnant women with antiphospholipid syndrome. METHODS: This multicentre, prospective, observational study was done at 76 centres in France. To be eligible for this study, women had to have diagnosis of antiphospholipid syndrome; have conceived before April 17, 2020; have an ongoing pregnancy that had reached 12 weeks of gestation; and be included in the study before 18 weeks of gestation. Exclusion criteria were active systemic lupus erythematosus nephropathy, or a multifetal pregnancy. Severe haemorrhage was defined as the need for red blood cell transfusion or maternal intensive care unit admission because of bleeding or invasive procedures, defined as interventional radiology or surgery, to control bleeding. The GR2 study is registered with ClinicalTrials.gov, NCT02450396. FINDINGS: Between May 26, 2014, and April 17, 2020, 168 pregnancies in 27 centres met the inclusion criteria for the study. 89 (53%) of 168 women had a history of thrombosis. The median term at inclusion was 8 weeks gestation. 16 (10%) of 168 women (95%CI 5-15) had a thrombotic (six [4%] women; 95% CI 1-8) or severe haemorrhagic event (12 [7%] women; 95% CI 4-12). There were no deaths during the study. The main risk factors for thrombotic events were lupus anticoagulant positivity at inclusion (six [100%] of six women with thrombosis vs 78 [51%] of 152 of those with no thrombosis; p=0·030) and placental insufficiency (four [67%] of six women vs 28 [17%] of 162 women; p=0·013). The main risk factors for severe haemorrhagic events were pre-existing maternal hypertension (four [33%] of 12 women vs 11 [7%] of 156 women; p=0·014), lupus anticoagulant positivity at inclusion (12 [100%] of 12 women vs 72 [49%] of 146 women; p<0·0001) and during antiphospholipid history (12 [100%] of 12 women vs 104 [67%] of 156 women; p=0·019), triple antiphospholipid antibody positivity (eight [67%] of 12 women vs 36 [24%] of 147 women; p=0·0040), placental insufficiency (five [42%] of 12 women vs 27 [17%] of 156 women; p=0·038), and preterm delivery at 34 weeks or earlier (five [45%] of 11 women vs 12 [8%] of 145 women; p=0·0030). INTERPRETATION: Despite treatment adhering to international recommendations, a proportion of women with antiphospholipid syndrome developed a thrombotic or severe haemorrhagic complication related to pregnancy, most frequently in the post-partum period. Lupus anticoagulant and placental insufficiency were risk factors for these life-threatening complications. These complications are difficult to prevent, but knowledge of the antenatal characteristics associated with them should increase awareness and help physicians manage these high-risk pregnancies.

Apixaban and rivaroxaban in obese patients treated for venous thromboembolism: Drug levels and clinical outcomes.

BACKGROUND: Direct oral anticoagulants (DOAC) use remains challenging in obese patients treated for Venous-Thrombo-Embolism (VTE) due to the paucity of prospective and dedicated studies. OBJECTIVE: To assess rivaroxaban and apixaban concentrations at different time-points after intake, in obese patients followed at a thrombosis center and treated for VTE; to define factors associated with DOAC levels outside the on-therapy ranges; and to evaluate bleeding and thrombosis rates during follow-up. METHODS: Observational prospective study in two French University hospitals. Apixaban or rivaroxaban concentrations were measured after the first visit, regardless of last intake in obese patients receiving DOAC for VTE. Concentrations were compared to published reference values for non-obese patients. Demographic, clinical, biological and therapeutic data were collected. Univariate and multivariate analyses were performed to identify factors associated to DOAC concentrations outside the on-therapy ranges. RESULTS: Out of the 146 patients included, 22 (15%) had DOAC concentrations outside the on-therapy ranges, mainly in the rivaroxaban group (n = 17). Age ≤ 63 years, use of rivaroxaban and time since last intake ≤8 h were associated with DOAC concentrations outside the on-therapy ranges, in multivariable analysis. During the median follow-up of 16 months, two (1%) patients receiving apixaban had recurrent VTE. No patient had major bleeding, 11 (8%) patients had minor bleeding. CONCLUSION: In this specific prospective bi-centric study dedicated to VTE obese patients, use of DOACs at fixed doses led to concentrations similar to those of non-obese patients in a high proportion of patients, without any effect of the BMI, and with risk-benefit profile comparable to non-obese patients.

Impact of Three Different Algorithms for the Screening of SSc-PAH and Comparison with the Decisions of a Multidisciplinary Team.

BACKGROUND: to compare three existing screening algorithms of pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc) with the results of a multidisciplinary team (MDT) meeting from a tertiary center. METHODS: we conducted a monocentric longitudinal study from 2015 to 2018. All patients with SSc according to LeRoy's classification were eligible. Patients were excluded in the case of missing data required by any of the three screening algorithms. The algorithms were applied for each patient at inclusion. Right heart catheterization (RHC) was performed based on the MDT decision. MDT members were all blinded from the results of the three algorithms regarding RHC recommendations. The RHC recommendations of each algorithm were compared with the MDT decision, and the impact on diagnosis and management was evaluated. RESULTS: 117 SSc patients were consecutively included in the study, and 99 had follow-up data over the three-year duration of the study (10 deaths). Among the 117 patients, the MDT suggested RHC for 16 patients (14%), DETECT algorithm for 28 (24%), ASIG for 48 (41%) and ESC/ERS 2015 for 20 (17%). Among the 16 patients who had RHC, SSc-PAH was diagnosed in seven. Among patients with an initial recommendation of RHC based on at least one algorithm but not according to the MDT meeting, no SSc-PAH was diagnosed during the three-year follow-up. Results were unchanged when the new 2018 definition of PAH was applied instead of the previous definition. CONCLUSION: a MDT approach appears interesting for the screening of SSc-PAH, with a significant reduction of RHC performed in comparison with dedicated algorithms. The specific relevance of a MDT for the management and follow-up of patients with RHC recommended by existing algorithms but with no PAH warrants further studies.

[Side effects of longterm oral corticosteroid therapy]. / Effets indésirables de la corticothérapie orale au long cours.

Side effects of long-term oral corticosteroid therapy. Systemic corticosteroid therapy has been used for over 70 years, and is still the cornerstone of the treatment of many conditions, in particular systemic, autoimmune or inflammatory diseases. Side effects of corticosteroids are numerous, and for most of them well known by prescribers. Nonetheless, guidelines for the prevention of corticosteroids toxicity are scarce, and the implementation of protective measures by prescribers is heterogenous. Hence, corticosteroids related complications entail a significant morbidity, which, importantly, could be largely prevented. We conducted therefore a systematic literature, through the Medline database, the Cochrane database and the grey literature until January 2021. After recalling the history of the discovery of corticosteroid therapy and its main pharmacological properties, we present the various complications associated with long-term corticosteroid therapy, and discuss the relevance of the preventive measures that may be proposed in daily practice in the light of available scientific evidence. This work highlights the importance of multidisciplinary follow-up, but above all of a thorough screening of the risk factors of complications at treatment initiation, and of a repeated evaluation of the complications all along the treatment course, in order to reduce the significant burden of morbidity associated with long-term corticosteroid therapy and to improve patient quality of life.

Effets indésirables de la corticothérapie orale au long cours. La corticothérapie systémique est utilisée depuis plus de 70 ans et reste la pierre angulaire du traitement de nombreuses affections. Ses effets indésirables sont nombreux et, pour la plupart, bien connus. Pour autant, les recommandations concernant leur prévention sont parfois manquantes, et souvent hétérogènes, y compris dans leur mise en œuvre par les prescripteurs. De ce fait, les complications induites par la corticothérapie sont à l'origine d'une morbidité importante, la plupart du temps évitables. Nous avons donc réalisé une revue systématique de la littérature, à travers les bases Medline, Cochrane et la littérature grise, jusqu'à janvier 2021. Après avoir rappelé l'histoire de la découverte de la corticothérapie et ses principales caractéristiques pharmacologiques, nous présentons les différentes complications associées à une corticothérapie au long cours et les mesures de prévention disponibles, en discutant leur efficacité et leur pertinence à la lumière des recommandations actuelles ou, à défaut, des dernières données scientifiques disponibles. Ce travail met en évidence l'importance du suivi multidisciplinaire des patients traités par corticothérapie systémique au long cours, mais surtout celle d'un dépistage préalable des facteurs associés à la survenue de complications et de réévaluations répétées de ces complications sous traitement, afin de diminuer le poids très important de la morbidité qui y est associée et ainsi d'améliorer la qualité de vie des patients.

Acute and Chronic Sarcoid Arthropathies: Characteristics and Treatments From a Retrospective Nationwide French Study.

Introduction: We aimed to analyze patients with acute and chronic joint involvements in sarcoidosis. Methods: This is a retrospective multicenter analysis of patients with proven sarcoidosis, as defined by clinical, radiological, and histological criteria, with at least one clinical and/or ultrasonographic synovitis. Results: Thirty-nine patients with sarcoid arthropathy were included, and among them 19 had acute sarcoidosis (Lofgren's syndrome). Joint involvement and DAS44-CRP were not significantly different in acute and chronic sarcoid arthropathies. Acute forms were more frequent than chronic sarcoid arthropathy in Caucasians, without any difference of sex or age between these 2 forms. Joint involvement was frequently more symmetrical in acute than chronic forms (100 vs. 70%; p < 0.05), with a more frequent involvement in wrists and ankles in acute forms, whereas the tender and swollen joint counts and the DAS44-CRP were similar between the 2 groups. Skin lesions were significantly more frequent in patients with acute forms [17 (89%) vs. 5 (25%); p < 0.05] and were erythema nodosum in all patients with Löfgren's syndrome and sarcoid skin lesions in those with chronic sarcoidosis. Among 20 patients with chronic sarcoidosis, treatment was used in 17 (85%) cases, and consisted in NSAIDs alone (n = 5; 25%), steroids alone (n = 5; 25%), hydroxychloroquine (n = 2; 20%), methotrexate (n = 3; 15%), and TNF inhibitors (n = 2; 10%). A complete/partial joint response was noted in 14 (70%) cases with a DAS44-CRP reduction of 2.07 [1.85-2.44] (from 3.13 [2.76-3.42] to 1.06 [0.9-1.17]; p < 0.05). Conclusion: Sarcoid arthropathies have different clinical phenotypes in acute and chronic forms and various treatment regimens such as hydroxychloroquine and methotrexate could be used in chronic forms.
