Semin Arthritis Rheum 2023; 59:152168. [PMID: 36736023 DOI: 10.1016/j.semarthrit.2023.152168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 01/03/2023] [Accepted: 01/16/2023] [Indexed: 01/20/2023]
Abstract
BACKGROUND/ PURPOSE Sarcopenia has been increasingly studied in systemic sclerosis (SSc), which is one of the most lethal autoimmune diseases, mainly due to lung involvement. Our objective was to study the associations of myopenia and/or myosteatosis with clinical features of SSc and subsequent adverse outcomes. METHODS This is a retrospective study with cross-sectional and longitudinal analyses, in which patients with SSc were consecutively included in the outpatient clinic of a tertiary university hospital between 2012 and 2021. Clinical and laboratory parameters of patients with SSc were collected from their medical records. Skeletal muscle mass was assessed on chest computed tomography (CT) at the level of the first lumbar vertebra (L1) by skeletal muscle area (SMA), skeletal muscle index ([SMI] SMA/height2), and skeletal muscle radiation attenuation (SMRA). Cut-off values for myopenia in women and men were SMA <70.1 cm² and <110.4 cm², and SMI <25.9 cm²/m² and <34.6 cm²/m², respectively; values for myosteatosis in women and men were SMRA <29.8 HU and <36.3 HU, respectively. In a subgroup of 31 patients followed-up between 2017 and 2019, the diagnostic properties of SMA, SMI, and SMRA by CT were compared with the appendicular skeletal muscle mass index (ASMI) by dual-energy X-ray absorptiometry (DXA). Low muscle quantity was defined according to the European Working Group on Sarcopenia in Older People 2: ASMI <5.5 kg/m2 in women and <7.0 kg/m2 in men. Afterwards, a better tomographic index was used for correlating with clinical and laboratory parameters. RESULTS Myopenia and/or myosteatosis were present in 75.7 % of patients with SSc. The prevalence rates according to each index were SMA 25.2%, SMI 12.1%, and SMRA 69.2%. In 73% of the patients with overweight/obesity (body mass index [BMI] ≥25 kg/m²), only SMRA was reduced. Considering ASMI as the gold standard, the sensitivity, specificity, positive and negative predictive values for SMA were 60%, 96.2%, 75% and 92.6%, respectively; for SMI, they were 40%, 96.2%, 66.7%, and 89.3%, respectively; for SMRA, these values were 60%, 34.6%, 15%, and 81.8%. Pearson's correlation coefficients were 0.73, 0.74, and 0.10 for SMA, SMI, and SMRA, respectively, and ASMI significantly agreed with SMA (kappa 0.611, p < 0.001) and SMI (kappa 0.431, p = 0.012). After adjustments in a multivariate model, BMI (p < 0.001) and female sex (p < 0.001) remained significantly associated with myopenia by SMA; BMI (p =0.010) remained significantly associated with low muscle mass by ASMI. CONCLUSION The SMA index at L1 level on chest CT was demonstrated to be an accurate measure that is useful for detecting myopenia in patients with SSc. BMI and male sex predicted low SMA and BMI was associated with low ASMI on DXA. STATEMENT OF CLINICAL SIGNIFICANCE In recent years, great advances have been made in sarcopenia-related research, resulting in broader knowledge on its definition, causes, diagnosis, and treatment options. Regarding the techniques used for assessing muscle composition, computed tomography (CT) was demonstrated by many studies to be an efficient and easy-to-use method that can be employed by professionals of different specialties, including rheumatologists. This study was able to demonstrate that although the L3 image was not present on CT, the analysis of SMA at the L1 level on chest CT proved to be an accurate and useful measure to detect myopenia in patients with SSc. This study identified some associated factors of myopenia and/or myosteatosis according to each method employed for assessing muscle composition. Reduced BMI and male sex were associated factors of myopenia when using SMA, and reduced BMI was associated with myopenia when employing ASMI by DXA. Finally, we highlight the need not to generalize the term "sarcopenia" in clinical studies assessing imaging parameters of body composition. The use of the terms myopenia and/or myosteatosis would be more adequate, because CT allows the assessment of muscle composition and not strength or physical performance.

Abstract
BackgroundRheumatoid arthritis (RA) patients usually present extra-articular manifestations (1,2), which affect muscle mass and, consequently, physical function (3). Among the various methods to assess muscle mass we tested muscle morphology by ultrasound (MU) to verify the associations of the quadriceps muscle with clinical features, muscle strength, functional capacity and physical function.ObjectivesTo assess the MU of the quadriceps muscle and verify the muscle quality assessed by the pennation angle and its associations with clinical features, muscle strength, functional capacity and physical function in RA patients.MethodsRA women, age ≥18years and who met 2010 American College of Rheumatology (ACR) criteria were included. Morphological parameters in quadriceps muscle consisted of the pennation angle of rectus femoris (RF), vastus intermedius (VI) and vastus lateralis (VL). RA activity was measured by 28-joint disease activity score (DAS28), muscle strength by handgrip and chair stand tests, functional capacity by health assessment questionnaire (HAQ), and physical function by timed-up-and-go (TUG) test and short physical performance battery (SPPB). Pearson’s or Spearman’s correlation coefficients were explored. The significance level was set at p ≤ 0.05 for all analyzes.ResultsEighty-one patients were included (age: 58.64±9.52 years old; DAS28: 3.24±1.34). Smaller pennation angle in rectus femoris (RF) were associated with lower handgrip strength (r= 0.224, p=0.044), chair stand test (r= -0.372, p=0.004), HAQ (r= -0.404, p=0.001), SPPB (r= 0.262, p=0.047), as well as higher disease activity by DAS-28 (r= -0.415, p<0.0001) and age (r= -0.290, p=0.009). Smaller pennation angle in vastus intermedius (VI) were associated with worse chair stand (r= -0.281, p=0.033), HAQ (r= -0.302, p=0.015) and higher disease activity by DAS-28 (r= -0.304, p=0.006). Lastly, smaller pennation angle in vastus lateralis (VL) were associated with worse chair stand (r= -0.290, p=0.027), as well as higher DAS-28 (r= -0.237, p=0.033) and age (r= -0.272, p=0.014).ConclusionThe pennation angles of the quadriceps muscle evaluated by ultrasound (RF, VI and VL muscles) were associated with chair stand test and DAS-28. In addition, the level of disease activity assessed by DAS-28 also appears to be affecting the quadriceps muscle. Finally, MU may be a useful method to evaluate the impact of the disease on skeletal muscle.References[1]Summers GD, Deighton CM, Rennie MJ, Booth AH.

Abstract
BackgroundSystemic sclerosis (SSc) patients are particularly prone to developing loss of muscle strength and worsening of physical performance due to decreased physical activity1. The lifestyle changes imposed by the SARS-CoV-2 outbreak have increased the incidence of sarcopenia in at-risk individuals2. However, the literature is scarce on the impacts of the COVID-19 pandemic on muscle strength and physical performance of SSc patients.Objectives(1) To assess the impact of the COVID-19 pandemic on muscle strength and physical performance of SSc patients and (2) to verify the associations of muscle strength and physical performance with inflammatory markers in a cohort study.MethodsSSc patients who met the ACR / EULAR 2013 classification criteria were included. Patients followed between 2019 and 2021. Muscle strength was measured by handgrip strength (kg) and sit and stand (SST, seconds) tests. Physical performance was measured by timed up and go (TUG, seconds) and short physical performance battery (SPPB, points). Inflammatory markers were measured by C-reactive protein (CRP). T test for independent samples, Mann-Whitney U test of independent samples and Spearman’s correlation coefficients were explored. The significance level was set at p ≤ 0.05 for all analyses.ResultsForty SSc patients concluded this study. At baseline, the mean age was 59 ±11.1 years old and the median disease duration was 13.1 (6.4-19.2) years. Patients had a median of 4.5 clinic visits (3.0-6.0) over the 2 years. The majority of patients were women (37, 92.5%). Ten patients (25%) had diffuse cutaneous disease, 30 patients (75%) non-diffuse cutaneous disease [25 patients (62.5%) had limited cutaneous disease, and 5 (12.5%) had sine scleroderma SSc]. The median of CRP was 2.9 (1.2-5.3). The median of handgrip strength was 20.0 (10.3-25.8) kg to the right hand and 19.0 (12.0-22.8) kg to the left hand. The median of SST was 14.4 (11.9-18.7) seconds. The median of TUG was 8.6 (7.7-9.5) seconds and the median of SPPB was 9.8 (9.0-11.0) points. The CRP was positively associated with SST (r=0.3, p=0.047) and TUG (r=0.3, p=0.029), and negatively with SPPB (r=-0.4, p=0.016). After 2 years of follow-up, the patients showed improvement in the left handgrip strength test (p=0.049) and SST (p=0.001). In physical performance, they showed improvement in the TUG test (p=0.005) and SPPB (p=0.001). The CRP was associated positively with TUG (r=0.4, p=0.033), no other associations were found.ConclusionDespite the COVID-19 pandemic and the restrictions imposed, in this population of patients with SSc, we did not detect any worsening in muscle strength and physical performance. Some of these parameters of muscle strength and physical performance were associated with the inflammatory marker CRP. More investigations are needed to assess the actual impact and possible associations.Table 1.Baseline comparison and after 2 years of patients with SScBaselineAfter 2 yearspCRP (mg/L),median (IQR)2.9 (1.2-5.3)2.3 (1.0-5.1)0.361Handgrip (kg),right, median (IQR)20.0 (10.3-25.8)20.5 (14.3-27.0)0.072left, median (IQR)19.0 (12.0-22.8)19.0 (14.0-26.0)0.049*SST (seconds),median (IQR)14.4 (11.9-18.7)11.6 (9.9-13.1)0.001*TUG (seconds),median (IQR)8.6 (7.7-9.5)7.9 (7.1-9.2)0.005*SPPB (points),median (IQR)9.8 (9.0-11.0)11.0 (10.0-12.0)0.001*SSc: systemic sclerosis; IQR: interquartile range; mg: milligram; L: liter; kg: kilograms grams; TUG: timed and up go; SST: sit and stand test; SPPB: short physical performance battery; PCR: C-reactive protein; and * significant difference of ≤0.05.References[1]Zaghlol, Rabab S et al. “Functional Disability Among Systemic Sclerosis Patients: Relation to Disease Characteristics and Quality of Life Parameters.” Current rheumatology reviews, 2021.[2]Bakaloudi, Dimitra Rafailia et al. “Impact of the first COVID-19 lockdown on body weight: A combined systematic review and a meta-analysis.” Clinical nutrition (Edinburgh, Scotland), 2021.Disclosure of InterestsNone declared

Abstract
BackgroundSystemic sclerosis (SSc) is a chronic disease characterized by autoimmunity, vasculopathy and fibrosis. During the disease course, patients with SSc are prone to accumulate multiple organ damage, increasing their vulnerability to adverse outcomes in comparison with individuals of the same age: a phenomenon called frailty. One of the most used definitions of frailty is the physical frailty phenotype (PFP) by Fried, et al. The PFP consists of 5 components: unintentional weight loss, exhaustion, muscle weakness, slow walking speed, and low physical activity. There is scarce data about frailty in patients with SSc.ObjectivesTo study the prevalence and clinical aspects of PFP in a sample of patients with SSc. Also, we aim to investigate the diagnostic accuracy of the Fatigue, Resistance, Ambulation, Illness and Loss of weight (FRAIL) scale and the Edmonton frailty scale (EFS) using the PFP as the reference standard.MethodsCross-sectional study, including patients with SSc according to the 2013 ACR-EULAR classification criteria or the criteria suggested by Le Roy and Medsger for early disease. PFP assessment was according to the original definition, except for physical activity domain, assessed with the International Physical Activity Questionnaire (IPAQ). Patients were classified according to Fried’s criteria in robust (0), pre-frail (1-2), and frail (≥3). FRAIL scale and EFS were also applied to the same individuals. The FRAIL score ranges from 0 to 5 and patients were classified as robust (0), pre-frail (1-2), or frail (≥3). The EFS score ranges from 0–17 and categorizes patients as not frail (0–4), vulnerable (5–6), mild frailty (7–8), moderate frailty (9–10), and severe frailty (≥11). For the diagnostic assessment of FRAIL scale and EFS, we estimated the area under the receiver operating characteristic curve (AUC), considering PFP as the reference standard and dichotomizing the results in frail vs. non-frail.ResultsBetween March and December 2019, 82 SSc patients were consecutively included. The mean age and disease duration were 60.4 (±10.6) and 13.4 (±8.2) years, respectively; 91.5% were women, and 19.5% with diffuse cutaneous SSc. The PFP distribution was: 8 (9.8%) robust, 47 (57.3%) pre-frail and 27 (32.9%) frail patients. The PFP domains´ frequencies were: low physical activity in 57 (69.5%), muscle weakness in 41 (50%), exhaustion in 34 (41.5%), unintentional weight loss in 15 (18.3%) and slow walking speed in 8 (9.8%) patients. Using the FRAIL scale, 44 (53.7%) patients were considered pre-frail and 25 (30.5%) frail. According to the EFS, 26 patients (31.7%) were classified as vulnerable and 12 (14.6%) as frail: mild in 6 (7.3%), moderate in 4 (4.9%) and severe in 2 (2.4%). The AUC against PFP was: 0.871 (95% CI 0.789-0.954, p<0.001) for FRAIL scale and 0.870 (95% CI 0.791-0.948, p<0.001) for EFS (Figure 1).ConclusionFrailty is prevalent in patients with long-standing SSc, and most of them are considered pre-frail or vulnerable. Low physical activity, muscle weakness and exhaustion are among the most frequent clinical aspects of the frailty phenotype. Both FRAIL scale and EFS showed overlapping diagnostic accuracy against PFP as the reference standard, and FRAIL scale seems to be more feasible than EFS.References[1]Rockwood MR, MacDonald E, Sutton E, Rockwood K, Baron M.

Morphological Parameters in Quadriceps Muscle Were Associated with Clinical Features and Muscle Strength of Women with Rheumatoid Arthritis: A Cross-Sectional Study. Diagnostics (Basel) 2021; 11:diagnostics11112014. [PMID: 34829361 PMCID: PMC8622079 DOI: 10.3390/diagnostics11112014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 10/24/2021] [Accepted: 10/25/2021] [Indexed: 12/27/2022] Open
Abstract
Background: Rheumatoid arthritis (RA) is an autoimmune, inflammatory and chronic disease that may lead to loss of muscle mass, muscle strength and decreased functionality. Our objectives are to assess the quadriceps muscle morphology by ultrasound (MU) and verify its associations with clinical features, muscle strength and physical function in RA patients. Methods: In this cross-sectional study, RA women (≥18 years) were included. Morphological parameters in quadriceps muscle consisted of the muscle thickness and pennation angle of rectus femoris (RF), vastus intermedius (VI) and vastus lateralis (VL). RA activity was measured by a 28-joint disease activity score (DAS28), muscle strength by handgrip and chair stand tests, and physical function by health assessment questionnaire (HAQ), timed-up-and-go (TUG) test and short physical performance battery (SPPB). Results: Fifty-five patients were included (age: 56.73 ± 9.46 years; DAS28: 3.08 ± 1.29). Muscle thickness in RF, VI and VL were negatively associated with age (RF, p < 0.001; VI, p = 0.013; VL, p = 0.002) and disease duration (RF, p < 0.001; VI, p = 0.005; VL, p = 0.001), and were positively associated with handgrip strength (RF, p = 0.015; VI, p = 0.022; VL, p = 0.013). In addition, decreased muscle thickness in VI (p = 0.035) and a smaller pennation angle in RF (p = 0.030) were associated with higher DAS-28 scores. Conclusion: Quadriceps muscle morphology by ultrasound appears to be affected by age, disease duration, disease activity and muscle strength in patients with RA. MU can be a useful method to evaluate the impact of the disease on skeletal muscle.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a chronic disease characterized by autoimmunity, vasculopathy, and visceral and cutaneous fibrosis. Vitamin D has several functions in the immunological system, and different studies have suggested a potential role in triggering autoimmune diseases. Patients with SSc may present with low serum levels of vitamin D, but the association between hypovitaminosis D and disease onset or any clinical manifestation is still obscure. Our goal was to verify the causal relationship between hypovitaminosis D and SSc onset or any particular clinical manifestation in the literature. METHODS A systematic literature review was performed through February 24th, 2021 on Pubmed, Lilacs/BIREME, and Cochrane databases. The eligible studies were read in full text, and, in the absence of exclusion criteria, were included in this review after consensus between two reviewers. RESULTS Forty articles met the eligibility criteria and the main results of each study are described. In most studies, SSc patients showed a higher prevalence of vitamin D deficiency and insufficiency compared to controls. Additionally, in some reports serum levels of vitamin D were inversely correlated with the severity of SSc. Oral supplementation did not seem to affect serum levels of vitamin D. Four of the included studies were with experimental models. CONCLUSION In conclusion, vitamin D deficiency seems to have a role in susceptibility to SSc, as well as in the clinical manifestations of the disease.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by vasculopathy and fibrosis, which can be subclassified into diffuse cutaneous (dSSc) and limited cutaneous (lSSc) subtypes. Previous studies suggest that an increase in monocytes can be a hallmark of various inflammatory diseases, including SSc. Our aim was to evaluate circulating blood monocyte subpopulations (classical, intermediate and non-classical) of SSc patients and their possible association with disease manifestations. METHODS Fifty consecutive patients fulfilling the 2013 ACR/EULAR classification criteria for SSc were included in a cross-sectional study. Monocyte subpopulations were identified based on their expression of CD64, CD14 and CD16, evaluated by flow cytometry, and were correlated with the clinical characteristics of the patients; furthermore, the expression of HLA-DR, CD163, CD169 and CD206 in the monocytes was studied. Thirty-eight age- and sex-matched healthy individuals were recruited as a control group. RESULTS SSc patients had an increased number of circulating peripheral blood monocytes with an activated phenotypic profile compared to healthy subjects. Absolute counts of CD16+ (intermediary and non-classical) monocyte subpopulations were higher in SSc patients. There was no association between monocyte subpopulations and the clinical manifestations evaluated. CONCLUSION We identified higher counts of all monocyte subpopulations in SSc patients compared to the control group. There was no association between monocyte subpopulations and major fibrotic manifestations. CD169 was shown to be more representative in dSSc, being a promising marker for differentiating disease subtypes.

Practical screening tools for sarcopenia in patients with systemic sclerosis. PLoS One 2021; 16:e0245683. [PMID: 33481872 PMCID: PMC7822499 DOI: 10.1371/journal.pone.0245683] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 01/05/2021] [Indexed: 11/26/2022] Open
Abstract
Introduction In view of the method of diagnosing sarcopenia being complex and considered to be difficult to introduce into routine practice, the European Working Group on Sarcopenia in Older People (EWGSOP) recommends the use of the SARC-F questionnaire as a way to introduce assessment and treatment of sarcopenia into clinical practice. Only recently, some studies have turned their attention to the presence of sarcopenia in systemic sclerosis (SSc).There is no data about performance of SARC-F and other screening tests for sarcopenia in this population. Objective To compare the accuracy of SARC-F, SARC-CalF, SARC-F+EBM, and Ishii test as screening tools for sarcopenia in patients with SSc. Methods Cross-sectional study of 94 patients with SSc assessed by clinical and physical evaluation. Sarcopenia was defined according to the revised 2019 EWGSOP diagnostic criteria (EWGSOP2) with assessments of dual-energy X-ray absorptiometry, handgrip strength, and short physical performance battery (SPPB). As case finding tools, SARC-F, SARC-CalF, SARC-F+EBM and Ishii test were applied, including data on calf circumference, body mass index, limitations in strength, walking ability, rising from a chair, stair climbing, and self reported number of falls in the last year. The screening tests were evaluated through receiver operating characteristic (ROC) curves. Standard measures of diagnostic accuracy were computed using the EWGSOP2 criteria as the gold standard for diagnosis of sarcopenia. Results Sarcopenia was identified in 15 (15.9%) patients with SSc by the EWGSOP2 criteria. Area under the ROC curve of SARC-F screening for sarcopenia was 0.588 (95% confidence interval (CI) 0.420–0.756, p = 0.283). The results of sensitivity, specificity, positive likelihood ratio (+LR), negative likelihood ratio (-LR) and diagnostic Odds Ratio (DOR) with the EWGSOP2 criteria as the gold standard were 40.0% (95% CI, 19.8–64.2), 81.0% (95% CI, 71.0–88.1), 2.11 (95% CI, 0.98–4.55), 0.74 (95% CI, 0.48–1.13) and 2.84 (95% CI, 0.88–9.22), respectively. SARC-CalF and SARC-F+EBM showed better sensitivity (53.3%, 95% CI 30.1–75.2 and 60.0%, 95% CI 35.7–80.2, respectively) and specificity (84.8%, 95% CI 75.3–91.1 and 86.1%, 95% CI 76.8–92.0, respectively) compared with SARC-F. The best sensitivity was obtained with the Ishii test (86.7%, 95% CI 62.1–96.3), at the expense of a small loss of specificity (73.4%, 95% CI 62.7–81.9). Comparing the ROC curves, SARC-F performed worse than SARC-CalF, SARC-F+EBM and Ishii test as a sarcopenia screening tool in this population (AUCs 0.588 vs. 0.718, 0.832, and 0.862, respectively). Direct comparisons between tests revealed differences only between SARC-F and Ishii test for sensitivity (p = 0.013) and AUC (p = 0.031). Conclusion SARC-CalF, SARC-F+EBM, and Ishii test performed better than SARC-F alone as screening tools for sarcopenia in patients with SSc. Considering diagnostic accuracy and feasibility aspects, SARC-F+EBM seems to be the most suitable screening tool to be adopted in routine care of patients with SSc.

Abstract
Introduction Vascular cell adhesion molecule-1 (VCAM-1) is involved in the progression of glomerular and tubulointerstitial injury in lupus nephritis (LN) and can be easily assessed in urine. The aim of this study was to assess urinary soluble VCAM-1 (uVCAM-1) as a biomarker of disease activity and treatment response in LN. Methods This prospective study enrolled 62 patients with class III, IV or V LN diagnosed within the last 3 years and divided them in two groups: with and without active nephritis at the inclusion, each group with 31 patients. At each visit, a urine sample was collected for uVCAM-1 evaluation and the nephritis status was assessed. Results Median uVCAM-1 level was elevated in patients with active compared to inactive LN (P < 0.001). The ROC curve of uVCAM-1 demonstrated an AUC of 0.84 and a cutoff of 47.2 ng/mgCr yielded a good sensitivity (74.2%) and specificity (74.2%) for the diagnosis of active LN. A significant correlation was found between uVCAM-1 level and renal activity scores and traditional biomarkers of LN. The level of uVCAM-1 dropped in patients with active LN who went into remission (P < 0.001), increased in patients who went into activity (P = 0.002) and did not change in patients who remained inactive (P = 0.797). The level of uVCAM-1 peaked during the flare of LN (P < 0.05). Conclusion The uVCAM-1 is a reliable biomarker that reflects renal disease activity and is useful for monitoring individual patients with lupus nephritis over time.

Abstract
Background:Systemic sclerosis (SSc) is a multisystem autoimmune disease of complex etiopathogeny, heterogeneous in its phenotypic expression and with a limited prognosis (1). The loss of muscle mass is a serious consequence of many chronic diseases and also is observed in SSc (2). This body composition alterations results in weakness, limitations and physical disability (3). SARC-F simple questionnaire, validated, is a key diagnostic feature for the fast assessment of geriatric syndromes associated with skeletal muscle wasting. However, there is no data about the SARC-F in SSc.Objectives:To assess the association between the SARC-F questionnaire with clinical features in patients with systemic sclerosis (SSc).Methods:Ninety-four patients diagnosed with systemic sclerosis were recruited and evaluated. Sarcopenia was assessed by the SARC-F questionnaire. Clinical features as disease duration time, comorbidities, body mass index (BMI), functional capacity by the Health Assessment Questionnaire (HAQ), inflammatory markers (C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), creatine phosphokinase (CPK), hemoglobin, creatinin and albumin) were medical record. Frequency analysis, descriptive analysis and Pearson’s correlation were performed. Statistical significance was considered as p<0,05.Results:Of the 94 patients analyzed, most were women (87/94;92.6%) with mean age of 60.5±10.3 years, median disease duration time of 11.2 (7.5-18.9) and median number of comorbidities was 1.00 (1.00-2.00). The mean of BMI was 25.9±4.7 Kg/m2. Twenty-one of the patients were classified as active or passive smokers, thirty-five said they were former smokers and thirty-eight never smoked. Sixty-nine (80, 2%) out of the ninety-four patients in the study had at least one type of comorbidity (mean 1, 44±1, 04). Eighty-three patients (88.3%) showed a SARC-F score without signs suggestive of sarcopenia (0-5) and eleven patients (11.7%) showed suggestive to sarcopenia (6-10). In HAQ, fifty-seven (60.6%) patients had mild incapacity, thirty-five (37.2%) had moderate incapacity, and two patients (2.2%) had severe incapacity. Higher SARC-F scores were associated with greater number of comorbidities (r=0.2; p=0.027), higher physical disability by HAQ (r= 0.5;p=0.000) and lower albumin levels (r= -0.3; p= 0.048). On other hand, SARC-F was not associated with time of diagnosis, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), creatine Phosphokinase (CPK), hemoglobin, hematocrit and creatinine.Conclusion:SARC-F scores were associated with comorbidities, physical disability and lower albumin levels in systemic sclerosis patients. Considering that comorbidities, physical disability and the albumin deficit enhances the patient’s muscle loss, SARC-F appears to be a good tool to screen sarcopenia risk factors in systemic sclerosis patients. Longitudinal studies are necessary to validate the SARC-F questionnaire in this population.References:[1]Hochberg MC et al. Sixth edit. (Elsevier, ed.). Philadelphia; 2015;[2]Sakuma K et al.

Abstract
Background:Sarcopenia is one of the major health problems in older patients and is defined as a progressive decrease in muscle mass and function1. Sarcopenia has only rarely been studied in systemic sclerosis (SSc) and its impact in clinical characteristics of SSc is poorly investigated.Objectives:To evaluate the associations between sarcopenia and clinical features in SSc patients.Methods:Cross-sectional study, including 82 patients who met the ACR/EULAR 2013 classification criteria for SSc. Dual-energy X-ray absorptiometry, handgrip strength, and short physical performance battery were used to assess sarcopenia according the European Working Group on Sarcopenia in Older People’s (EWGSOP) diagnostic criteria updated in 20191. Malnutrition was evaluated according to the European Society of Clinical Nutrition and Metabolism (ESPEN)2, using the Malnutrition Universal Screening Tool (MUST) to screen risk for malnutrition.Results:The mean age was 60.4 years and 91.5% were women (table 1). Sarcopenia was identified in 15 (18.3%) SSc patients. Malnutrition was diagnosed in 12 (14.6%) and was more common in patients with sarcopenia (P=0.038). Also, there were significant differences between patients with and without sarcopenia regarding Body Mass Index (P=0.001), Fat Free Mass Index (P<0.001), knee extension strength (P=0.049), and Timed Up and Go test (P=0.041). There were no differences regarding age, disease duration, Rodnan skin score (mRSS), FVC and DLCO.Table 1.Clinical characteristics of SSc patients with and without sarcopenia.

Abstract
Background:Interstitial lung disease (ILD) is the main cause of death in Systemic Sclerosis (SSc). Chest CT is the gold standard in detecting ILD although it is not easy to understand its prognostic value. ILD qualitative assessment is almost worthless. Goh et al. semi quantitative score of ILD extent is related to mortality risk but it is burdened by relevant inter/intra-readers variability. An operator independent algorithm based on voxel-wise analysis proved to identify SSc patients with an increased risk of mortality according to prediction models.Objectives:To verify if quantitative analysis of chest CT (QCT) predict 10 years-mortality in SSc patients.Methods:SSc patients with availability of a chest CT were enrolled in 13 different centers. The CT voxel-wise analysis with a free software (www.horosproject.com) provided QCT indexes: kurtosis, skewness, mean lung attenuation and standard deviation. Patients characteristics, autoimmune profile and pulmonary function test were collected. The follow-up interval lasted from the date of chest CT to the one of the last visit or death. Each QCT index cutoff, established in a previous study (1), clustered patients in two groups. Kaplan-Meier analysis estimated and compared survival in the above mentioned groups. p < 0.05 was considered statistically significant.Results:Five hundred sixty three SSc patients were enrolled (35938 patient-months); 52.4% had ILD detectable at CT scan. For each QCT index cutoff the cohort was split in two subgroups without differences in terms of sex, age, disease duration, autoimmune profile. All QCT indexes’ cutoff selected subgroups with statistically different survival rate (e.g in Figure 1).Figure 1Conclusion:QCT can arise as the new gold standard in identifying SSc patients with poor prognosis. The real possibility to stratify SSc subjects according mortality risk will have a pivotal role in ILD treatment decisional process with the incoming anti-fibrotic drugs.References:[1]Ariani A et al.

Abstract
Background:The traditional lupus nephritis (LN) biomarkers are not sensitive nor specific enough for detecting ongoing disease activity and early relapse of nephritis and they do not reflect kidney damage nor have prognostic value1. Urinary biomarkers are directly excreted by the kidney and are easily obtained. They can also differentiate the renal activity of the disease from other organic manifestations more accurately than the serum biomarkers2. Vascular cell adhesion molecule-1 (VCAM-1) is involved in the progression of glomerular and tubulointerstitial injury in LN and its soluble form can be easily assessed in urine (uVCAM-1)3. Several studies correlated the uVCAM-1 levels with urine protein-creatinine ratio (UPC), with general disease activity and with active LN3.Objectives:To assess uVCAM-1 as a biomarker of disease activity and treatment response in LN.Methods:This prospective study enrolled patients with class III, IV or V LN diagnosed within the last three years and divided them in two groups: with and without active nephritis at the inclusion. The patients with active nephritis were included before they started a new immunosuppressive treatment. Active LN was defined as proteinuria (UPC≥0.5) plus active urinary sediment (hematuria, leukocyturia or cellular hematic/granular casts). At each visit, a urine sample was collected for uVCAM-1 evaluation and the nephritis status was accessed.Results:Median uVCAM-1 level was elevated in patients with active compared to inactive LN (p<0.001). The ROC curve of uVCAM-1 demonstrated an AUC of 0.84 and a cutoff of 47.2 ng/mgCr yielded a good sensitivity (74.2%) and specificity (74.2%) for the diagnosis of active LN. A significant correlation was found between uVCAM-1 level and renal activity scores and traditional biomarkers of LN (table 1). The level of uVCAM-1 dropped in patients with active LN who went into remission (p<0.001), increased in patients who went into activity (p=0.002) and did not change in patients who remained inactive (p=0.797) (figure 1). The level of uVCAM-1 peaked during the flare of LN (p<0.05) (figure 2).Table 1.Correlations between urinary soluble VCAM-1 and other LN biomarkers/disease scoresLN biomarkers/disease scoresVCAM-1SLEDAI-2k0.597***Renal SLEDAI0.569***Renal SLAM-R0.470***Renal SLICC0.620***Anti-dsDNA0.342**C3-0.344**C4-0.382**UPC0.654***Spearman’s correlation coefficients*pvalue <0.05; **pvalue <0.01; ***pvalue <0.001C, complement; LN, lupus nephritis; SLEDAI, Systemic Lupus Erythematosus Disease Activity Index; renal SLAM-R, The renal Systemic Lupus Activity Measure revised; renal SLICC, The Systemic Lupus International Collaborating Clinics renal activity/response exercise; UPC, urine protein-creatinine ratio.Conclusion:The uVCAM-1 is a reliable biomarker that reflects renal disease activity and is useful for monitoring individual patients with lupus nephritis over time.References:[1]Mok CC.

Abstract
Background:Because the method of diagnosing sarcopenia is complex and is considered to be difficult to introduce into routine practice, the European Working Group on Sarcopenia in Older People’s (EWGSOP) recommends use of the SARC-F questionnaire as a way to introduce assessment and treatment of sarcopenia into clinical practice1. Only recently, some studies have focused their attention on the presence of sarcopenia in systemic sclerosis (SSc) and there is no data about the performance of SARC-F in this population.Objectives:To test the diagnostic properties of the SARC-F questionnaire for sarcopenia screening in SSc patients.Methods:Cross-sectional study, including 94 SSc patients assessed by clinical evaluation, laboratory and pulmonary function tests. Sarcopenia was evaluated using the EWGSOP diagnostic criteria updated in 2019 (EWGSOP2): dual-energy X-ray absorptiometry, handgrip strength, and short physical performance battery (SPPB)1. Participants also completed the SARC-F questionnaire. The questionnaires’ performances were evaluated through receiver operating characteristic (ROC) curves and standard measures of diagnostic accuracy were computed using the EWGSOP2 criteria as the gold standard for diagnosis of sarcopenia.Results:Sarcopenia was identified in 15 (15,9%) SSc patients by the EWGSOP2 criteria. Area under the ROC curve of SARC-F screening for sarcopenia was 0.588 (95% confidence interval (CI) 0.482, 0.688) (figure 1). The results of sensitivity, specificity, positive likelihood ratio (PLR) and negative likelihood ratio (NLR) with the EWGSOP2 criteria as the reference standard were 35.71 [95% CI, 12.76-64.86], 81.01 (95% CI, 70.62-88.97), 1.88 (95% CI, 0.81-4.35) and 0.79 (95% CI, 0.53-1.19), respectively. The optimal cut-off point of SARC-F in our sample was ≥ 4 (Youden index: 0.21), the same cut-off point recommended in the literature2,3. Only 6 (40%) out of the 15 participants with sarcopenia were identified by the SARC-F questionnaire in our population. However, the SARC-F properly identified 4 out of 5 patients who had severe sarcopenia.Conclusion:This is the first study to evaluate the performance of SARC-F questionnaire for sarcopenia screening in patients with SSc. Although it appropriately identifies severe cases of sarcopenia, the SARC-F alone may not be an adequate screening tool in high-risk populations, such as SSc, that may benefit from early intervention and treatment.References:[1]Cruz-Jentoft AJ, Bahat G, Bauer J, et al.

Abstract
Background:As structural damage is irreversible and strongly associated with functional disability1, it is an important outcome to be prevented in rheumatoid arthritis (RA). Acute phase markers, rheumatoid factor (RF) and anti-citrullinated protein (anti-CCP) positivity are important predictors of erosive disease2. Previous studies conducted in real life setting have divergent results regarding the role of disease activity in radiographic progression3,4.Objectives:To evaluate the impact of disease activity and biologic disease modifying anti-rheumatic drugs (bDMARDs) on radiographic progression of established RA in clinical practice in southern Brazilian public health system.Methods:Longitudinal retrospective study including patients with RA (1987 ACR criteria) treated with bDMARDs and followed from 2015 to 2019. Clinical and demographic data were collected at baseline. Radiographs of hands and feet were performed yearly. X-rays were scored according to the van der Heijde-modified total Sharp method (vdH-mTSS) in known chronological order. Clinical relevant radiographic progression (CRRP) was defined as an increase ≥3 units on the score per year5.Demographic, clinical, and radiographic characteristics of RA patients with or without relevant progression were compared with Fisher exact and Mann-Whitney test.Results:Seventy-five patients were included. The patients’ characteristics are shown in table 1. Twenty three (30%) patients presented CRRP at any time point of the follow up (figure 1). Mean DAS28-ESR at baseline was higher in patients who progressed radiographically, than those who did not progress (4.8±1.1 vs 3.5±1.1; p < 0.001). No patient in remission at baseline presented with CRRP. Radiographic progression occurred in 15% of patients in low disease activity, 34% of patients in moderate disease activity and 57% of patients in high disease activity at baseline, depicting a linear relation between categories of disease activity and CRRP. RF, anti-CCP, disease duration, educational level, smoking status, total vdH-mTSS at baseline, number and duration of biologic DMARDs were not associated with CRRP. No single biologic DMARD was associated with worse radiological prognosis.Table 1.Baseline characteristics and bDMARD treatment during 5 years of follow upCharacteristicsN = 75Age, yrs, mean ± SD58.1 ± 10.1Female, n (%)65 (86.6)Disease duration, yrs, mean ± SD16.2 ± 7.6IgM RF positivity, n (%)69 (92)Anti-CCP positivity, n (%)27 (75) *DAS28-ESR, mean ± SD4.2 ± 1.0Educational level, n(%) Elementary school (≤ 8years)49 (65) Intermediate school (9-12 years)23 (30,6) University/college degree3 (4)SmokingCurrent or former31 (41.3)Never44 (58,7)vdH-mTSS, median (IQR)21 (5-53)Number of bDMARD, mean ± SD2.4 ± 1.1Duration of bDMARD, yrs, mean ± SD7.4 ± 2.6Methotrexate use, n, %61 (81)Biologic DMARD184**TNF inhibitors, n, %106 (57.6)Tocilizumab, n, %30 (16.3)Abatacept, n, %25 (13.6)Rituximab, n, %23 (12.5)RF rheumatoid fator anti-CCP anti-citrullinated protein bDMARD biologic disease-modifying anti-rheumatic drug ESR erythrocyte sedimentation rate DAS28 disease activity in 28 joints vdH-mTSS van der Heijde-modified total Sharp score IQR interquartile range *information available from 36 patients **all bDMARD treatmentsConclusion:In contrast to controlled clinical trials, real-world studies have shown that patients with RA treated with bDMARD still develop radiological progression.

Cachexia in patients with rheumatoid arthritis: a cohort study. Clin Rheumatol 2020; 39:3603-3613. [PMID: 32447598 DOI: 10.1007/s10067-020-05119-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Revised: 04/13/2020] [Accepted: 04/21/2020] [Indexed: 12/28/2022]
Abstract
BACKGROUND Rheumatoid arthritis (RA) is an inflammatory disease that leads to altered body composition. The loss of lean mass with a preservation or increase in fat mass has been termed rheumatoid cachexia (RC), to contrast with classic cachexia, which is characterized by severe weight loss. There are limited data on the prevalence and progression of cachexia in RA over time, as well as on associated factors. Our aim was to determine the prevalence of cachexia and to determine associations with potential factors. METHODS This prospective cohort study recruited consecutively patients diagnosed with RA and followed for 1 year. The assessments were performed: clinical features, body composition, and physical function. RC and classic cachexia were assessed by several established diagnostic criteria. The pairwise Student's t test, Chi-square test, and GEE were performed (accepted at p ≤ 0.05). RESULTS Of 90 patients recruited, 81 completed the study. Most patients were women (88.9%), and the mean age was 56.5 ± 7.3 years. At baseline, the median DAS28-CRP was 3.0 (IQR, 1.0-3.0), 13.3-30.0% of the included patients had RC, while none met criteria for classic cachexia. The prevalence of cachexia did not change after 12 months. Disease activity status and treatment with biologic disease-modifying antirheumatic drugs were significantly associated with changes on body composition and physical function (p < 0.05). CONCLUSIONS In this cohort, RC was common, while classic cachexia was absent. Disease activity and use of biologic therapies were associated with changes on body composition and physical function, underscoring the importance of aiming for remission when treating RA.

Overall mortality in combined pulmonary fibrosis and emphysema related to systemic sclerosis. RMD Open 2019; 5:e000820. [PMID: 30886735 PMCID: PMC6397433 DOI: 10.1136/rmdopen-2018-000820] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2018] [Revised: 11/13/2018] [Accepted: 12/17/2018] [Indexed: 12/02/2022] Open
Abstract
Objectives This multicentre study aimed to investigate the overall mortality of combined pulmonary fibrosis and emphysema (CPFE) in systemic sclerosis (SSc) and to compare CPFE-SSc characteristics with those of other SSc subtypes (with interstitial lung disease—ILD, emphysema or neither). Methods Chest CTs, anamnestic data, immunological profile and pulmonary function tests of patients with SSc were retrospectively collected. Each chest CT underwent a semiquantitative assessment blindly performed by three radiologists. Patients were clustered in four groups: SSc-CPFE, SSc-ILD, SSc-emphysema and other-SSc (without ILD nor emphysema). The overall mortality of these groups was calculated by Kaplan-Meier method and compared with the stratified log-rank test; Kruskal-Wallis test, t-Student test and χ² test assessed the differences between groups. P<0.05 was considered statistically significant. Results We enrolled 470 patients (1959 patient-year); 15.5 % (73/470) died during the follow-up. Compared with the SSc-ILD and other-SSc, in SSc-CPFE there was a higher prevalence of males, lower anticentromere antibodies prevalence and a more reduced pulmonary function (p<0.05). The Kaplan-Meier survival analysis demonstrates a significantly worse survival in patients with SSc-CPFE (HR vs SSc-ILD, vs SSc-emphysema and vs other-SSc, respectively 1.6 (CI 0.5 to 5.2), 1.6 (CI 0.7 to 3.8) and 2.8 (CI 1.2 to 6.6). Conclusions CPFE increases the mortality risk in SSc along with a highly impaired lung function. These findings strengthen the importance to take into account emphysema in patients with SSc with ILD.

Abstract
Renal involvement is one of the main complications of systemic lupus erythematosus, causing a significant impact on patients' morbidity and mortality. Renal biopsy is still the gold standard of diagnosis, but it has many limitations. In this sense, several recent studies aim to identify biomarkers that not only predict disease activity and renal histology, but also lead to earlier treatment. In previous studies, the soluble vascular cell adhesion molecule-1 measured in urine showed a strong association with the presence of lupus nephritis, with clinical and histological activity indexes of the disease and with more severe renal lesions. This paper reviews the main urinary biomarkers of lupus nephritis that have been studied, with special emphasis on vascular cell adhesion molecule-1 results.

Treating psoriatic arthritis to target: discordance between physicians and patients' assessment, non-adherence, and restricted access to drugs precluded therapy escalation in a real-world cohort. Clin Rheumatol 2018; 38:961-968. [PMID: 30511296 DOI: 10.1007/s10067-018-4383-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Revised: 11/19/2018] [Accepted: 11/26/2018] [Indexed: 01/10/2023]
Abstract
The treat-to-target strategy (T2T) was associated with better outcomes in psoriatic arthritis (PsA) compared to standard care in clinical trials. This study aimed to analyze factors precluding treatment optimization in a T2T strategy conducted in a real-world cohort of PsA patients. A retrospective cross-sectional study nested in a cohort was conducted. Medical records of patients ≥ 18 years old, fulfilling CASPAR criteria and with at least one visit in the PsA clinic, were reviewed. Demographic data, current medication, and minimal disease activity (MDA) criteria were recorded. Reasons for the non-escalation of therapy in patients who were not classified as MDA were reported as absolute and relative frequencies. In the 8-month period, 131 visits (corresponding to 74 patients) were conducted. The MDA criteria were available in 113 visits (86.3%) and patients were classified as MDA in 31.0% of the visits (N = 35/113). Although in 69.0% of the visits patients were not in MDA, (N = 78/113), therapy was adjusted in only 42.3% (N = 33/78). Reasons precluding treatment escalation in non-MDA subjects were physician's impression of remission (57.7%, N = 26), non-adherence to previous prescription (17.8%, N = 8), restricted access to drugs (17.8%, N = 8), adverse events (11.1%, N = 5), poor understanding of medication instructions (6.7%, N = 3), patient's refusal to escalate therapy (4.4%, N = 2), and recent change in therapy (2.2%, N = 1). Discordance between the physician's clinical evaluation and the MDA criteria, non-adherence to prescription, and poor access to drugs were the main factors precluding escalation of therapy in a T2T strategy in a real-world PsA cohort.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) and acquired immunodeficiency syndrome (AIDS) share many clinical manifestations and laboratory findings, therefore, concomitant diagnosis of SLE and human immunodeficiency virus (HIV) can be challenging. METHODS Prospective cohort with 602 patients with SLE who attended the Rheumatology Clinic of the Hospital de Clínicas de Porto Alegre since 2000. All patients were followed until 01 May 2015 or until death, if earlier. Demographic, clinical and laboratory data were prospectively collected. RESULTS Out of the 602 patients, 11 presented with the diagnosis of AIDS (1.59%). The following variables were significantly more prevalent in patients with concomitant HIV and SLE: neuropsychiatric lupus (10.9% vs. 36.4%; p = 0.028) and smoking (37.6% vs. 80%; p = 0.0009) while malar rash was significantly less prevalent in this population (56% vs. 18.2%; p = 0.015). Nephritis (40.5% vs. 63.6%; p = 0.134) and hemolytic anemia (28.6% vs. 54.5%; p = 0.089) were more prevalent in SLE patients with HIV, but with no statistical significance compared with SLE patients without HIV. The SLICC damage index median in the last medical consultation was significantly higher in SLE patients with HIV (1 vs. 2; p = 0,047). CONCLUSIONS Our patients with concomitant HIV and SLE have clinically more neuropsychiatric manifestations. For the first time, according to our knowledge, higher cumulative damage was described in lupus patients with concomitant HIV infection. Further studies are needed to elucidate this complex association, its outcomes, prognosis and which therapeutic approach it's best for each case.

Capillary loss on nailfold capillary microscopy is associated with mortality in systemic sclerosis. Clin Rheumatol 2017; 37:475-481.

Abstract
The objective of this study is to test the association of the severity of nailfold capillaroscopy (NFC) abnormalities with mortality in systemic sclerosis (SSc). One hundred and seventy SSc patients underwent an extensive evaluation (including high-resolution computed tomography, pulmonary function tests, and Doppler echocardiography) at baseline following a standard protocol. Capillary loss on NFC was evaluated using the avascular score (AS, ranging from 0 to 3), and the mean number of ectasias, megacapillaries, and hemorrhages per finger was also recorded. After a mean period of 10.1 ± 4.9 years, the life status of the patients was ascertained. Univariate and multivariate Cox proportional hazards models were used for statistical analysis. Overall, 73 patients died. By univariate Cox analysis, the AS was significantly associated with mortality (hazard ratio [HR] = 1.64, 95% CI 1.22 to 2.19, p = 0.001). In our study, this association was stronger than that of race, gender, anticentromere antibodies, anti-topoisomerase I antibodies, and form of disease and had similar strength to that of skin score in univariate analyses. However, after controlling for a combination of variables (age, skin score, gender, race, signs of peripheral ischemia, and extent of interstitial lung disease, all independently associated with mortality), the association of AS with mortality was blunted (HR = 1.15, 95% CI 0.80 to 1.65, p = 0.445). Other NFC variables were not related to mortality. AS was associated with higher risk of death and, despite not having an independent association with mortality after controlling for a set of demographic and clinical variables, may be a useful tool in prognostic evaluation of SSc.

Abstract
Neuropsychiatric disorders associated with systemic lupus erythematosus are very common. Treatment generally consists of glucocorticoids and immunosuppressive therapy; however, some cases are unresponsive. Electroconvulsive therapy (ECT) is a recognized treatment modality in psychiatry and is an option for refractory cases of neuropsychiatric lupus. This report describes three cases of neuropsychiatric lupus that improved with ECT after failure of antipsychotics and immunosuppressive therapy. All cases met DSM-5 criteria for catatonia (case 1: agitation, stereotypies, and grimacing; case 2: stupor, mutism, and grimacing; case 3: agitation, mutism, and stereotypies); therefore, ECT was indicated. This case series shows that ECT can be a therapeutic option in patients with neuropsychiatric lupus, especially when associated with catatonia and unresponsive to conventional treatment.
