Abstract
Thiazolidinediones (TZD) are synthetic molecules that have a range of biological effects, including antifibrotic and anti-inflammatory, and they may represent a promising therapeutic strategy for systemic sclerosis (SSc). The aim of this study was to investigate the immunomodulatory and antifibrotic properties of LPSF/GQ-16, a TZD derivative, in peripheral blood mononuclear cells (PBMC) from SSc patients and in a murine model of SSc HOCl-induced. The PBMC of 20 SSc patients were stimulated with phytohemagglutinin (PHA) and treated with LPSF/GQ-16 for 48 h, later cytokines in the culture supernatants were quantified by sandwich enzyme-linked immunosorbent assay (ELISA) or cytometric bead array (CBA). Experimental SSc was induced by intradermal injections of hypochlorous acid (HOCl) for 6 weeks. HOCl-induced SSc mice received daily treatment with LPSF/GQ-16 (30 mg/kg) through intraperitoneal injections during the same period. Immunological parameters were evaluated by flow cytometry and ELISA, and dermal and pulmonary fibrosis were evaluated by RT-qPCR, hydroxyproline dosage and histopathological analysis. In PBMC cultures, it was possible to observe that LPSF/GQ-16 modulated the secretion of cytokines IL-2 (p < 0.001), IL-4 (p < 0.001), IL-6 (p < 0.001), IL-17A (p = 0.006), TNF (p < 0.001) and IFN-γ (p < 0.001). In addition, treatment with LPSF/GQ-16 in HOCl-induced SSc mice promoted a significant reduction in dermal thickening (p < 0.001), in the accumulation of collagen in the skin (p < 0.001), down-regulated the expression of fibrosis markers in the skin (Col1a1, α-Sma and Tgfβ1, p < 0.001 for all) and lungs (Il4 and Il13, p < 0.001 for both), as well as reduced activation of CD4 + T cells (p < 0.001), B cells (p < 0.001) and M2 macrophages (p < 0.001). In conclusion, LPSF/GQ-16 showed immunomodulatory and antifibrotic properties, demonstrating the therapeutic potential of this molecule for SSc.

Abstract
BACKGROUND Muscle dysfunction may cause disability and reduce the quality of life of patients with systemic sclerosis (SSc) when compared to healthy individuals. However, the literature on the topic is scarce and uses several criteria for assessing muscle dysfunction in this population. OBJECTIVES To compare diaphragm and quadriceps muscle thickness, diaphragm mobility, and handgrip strength between patients with SSc and healthy individuals. METHOD This cross-sectional study included 16 patients with SSc and 16 self-reported healthy individuals matched for age. We assessed quadriceps and diaphragm thickness and diaphragmatic mobility (ultrasound), handgrip strength (hand-held dynamometer), and respiratory muscle strength (manovacuometer). Patients also responded to the Health Assessment Questionnaire Disability Index and the International Physical Activity Questionnaire. RESULTS Patients with SSc presented lower quadriceps thickness (p < 0.0001), diaphragmatic mobility (p = 0.01), handgrip (p < 0.0001), and respiratory muscle strength (p < 0.0001) than healthy individuals. A moderate positive correlation was observed between handgrip strength and quadriceps thickness in patients with SSc (rho = 0.576; p = 0.02). CONCLUSIONS Patients with SSc presented reduced quadriceps thickness, diaphragmatic mobility, handgrip, and respiratory muscle strength when compared to healthy individuals Also, handgrip strength was correlated with quadriceps thickness in patients with SSc, suggesting that loss of muscle mass accompanies loss of peripheral muscle strength group of patients. Key Points • SSc patients presented reduced quadriceps thickness and diaphragmatic mobility • SSc patients have reduced handgrip and respiratory muscle strength • Lower handgrip muscle strength correlated with lower quadriceps thickness.

Abstract
OBJECTIVE To investigate the effectiveness of Maitland's joint mobilization and therapeutic exercises on the functionality of the hands in patients with systemic sclerosis. DESIGN Randomized controlled trial. SETTING Tertiary university hospital. SUBJECTS Twenty-four patients diagnosed with systemic sclerosis according to ACR/EULAR 2013 criteria; age ⩾18 years and Cochin Hand Functional Scale (COCHIN) score ⩾10. They were randomized to physical therapy group (n = 12) or control group (n = 12). INTERVENTIONS The physical therapy group received joint mobilization and undertook therapeutic exercises, twice a week, for 12 weeks, and received a booklet with information about the disease. The control group only received the booklet about the disease. MAIN MEASURES The primary outcome measure was functionality of the hands (COCHIN). The secondary outcomes measures were disability (SHAQ), pain (visual analogic scale), range of motion (HAMIS and Delta finger-to-palm), grip strength (JAMAR dynamometer), and quality of life (SF12). RESULTS Twenty-two patients were female, with a mean age of 47.4 ± 11.1 years and 18 had limited cutaneous form. The physical therapy group showed a decrease of 11.33 points in the COCHIN in comparison with the control group (P = 0.09). There was a significant increase in range of motion by HAMIS (3.00 ± 1.48 vs 5.42 ± 2.64, P = 0.008), reduction in pain VAS (3.42 ± 2.78 vs 7.75 ± 2.53, P < 0.001), and increase in the physical component of SF12 (38.51 ± 9.60 vs 32.65 ± 9.10, P = 0.038). CONCLUSION Maitland's joint mobilization and therapeutic exercises improved the functionality of the hands, reduced pain in the hands and wrists, increased range of motion, and improved quality of life in patients with systemic sclerosis.

Abstract
INTRODUCTION Systemic sclerosis (SSc) is a rare complex disease characterized by vascular damage, autoimmunity, and extensive skin and internal organs fibrosis. Galectin-3 (Gal-3) is encoded by gene LGALS3 (Lectin, Galactoside-Binding, Soluble, 3; 14q22.3) and it has been reported to play a central role in self-tolerance, inflammation, and fibrosis. OBJECTIVE To investigate associations among LGALS3 single nucleotide polymorphisms (SNPs) and serum levels Gal-3 and SSc susceptibility and their clinical features. METHODS A case-control study with 88 patients and 151 matched controls was performed. LGALS3 variants were analyzed by the TaqMan real-time polymerase chain reaction (PCR) system whereas Gal-3 serum levels were measured by sandwich enzyme linked immunosorbent assay (ELISA). Associations among genotypes, clinical features, and Gal-3 levels were performed by univariable and multivariable analysis through statistical packages. RESULTS The LGALS3 rs4652 A/C genotype was more frequent in SSc patients than controls according to overdominant model [OR 1.89 (CI 95% 1.01 - 3.52); p = .046]. Also, LGALS3 rs4652 C/C polymorphic genotype was associated with lower patient Gal-3 levels (p = .03) and control group (p = 0.005), as noted by generalized linear model (GLM). The LGALS3 rs1009977 G/T controls showed higher Gal-3 levels than wild-type and polymorphic genotypes (p = .03); however, in SSc patients, no difference was found. None of the LGALS3 SNPs or Gal-3 levels was associated with clinical manifestations in SSc patients. Considering only the SSc group, GLM analysis pointed LGALS3 rs4652 and rs2075601, pulmonary arterial hypertension (PAH), myopathy, and health assessment questionnaire (HAQ) and scleroderma health assessment questionnaire (SHAQ) as important predictors for Gal-3 levels. CONCLUSION The LGALS3 rs4652 A/C was more frequent in SSc patients and related to lower Gal-3 levels. These findings were corroborated through a GLM to estimate Gal-3 values. Also, by model equations, Gal-3 levels may be predicted by HAQ, SHAQ, PAH, myopathy, and LGALS3 rs4652 and rs2075601 factors. In these ways, we suggest that galectins may be promising biomarkers to identify susceptibility to SSc as well as to identify HAQ, SHAQ, PAH, and myopathy outcomes.

Abstract
Introduction: Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by progressive fibrosis of the skin and internal organs that promotes high morbidity and mortality. Objective: To evaluate the functionality, disability and quality of life of patients with systemic sclerosis and to compare the clinical forms of the disease. Methods: Cross-sectional, descriptive and analytical study performed at the Rheumatology Clinic of the Hospital das Clínicas of the Federal University of Pernambuco (HC-UFPE) from August 2018 to April 2019. The non-probabilistic, convenience sample consisted of 60 patients diagnosed with systemic sclerosis (SSc), followed at the Rheumatology outpatient clinic of the Hospital das Clínicas, Federal University of Pernambuco. To evaluate the outcomes, the following instruments were used: Cochin Hand Functional Scale (CHFS) for hand function; 12-Item Short-Form Health Survey (SF-12) for quality of life; and Scleroderma Health Assessment Questionnaire (SHAQ) for functionality and disability. Results: The mean results for CHFS, SHAQ, SF-12 Physical Component Summary and SF-12 Mental Component Summary were 14.5 (6.0-29.75), 1.01±0.56, 35.04±8.09, 40.94±10.56, respectively. There were no significant differences in CHFS outcomes between patients with diffuse and limited forms of SSc, SHAQ and the mental component of SF-12. However, in the physical component of SF-12, a better score was found in patients with the diffuse form of the disease (p=0.04). Conclusion: Patients with SSc present an important impairment of hand function, quality of life and functional capacity, and those with limited cutaneous form present worse scores of the physical component in the evaluation of quality of life.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic and progressive inflammation that can cause a high degree of disability in affected individuals. Proinflammatory cytokines play central roles in the development of degradative and inflammatory responses in RA. IL-29 has been identified in RA and reported as a biomarker of the disease. OBJECTIVE To analyze serum levels and accuracy of IL-29 in RA patients compared to healthy subjects and patients with other rheumatic diseases. METHODS IL-29 serum levels were measured in 121 patients with RA, 53 patients with systemic lupus erythematosus (SLE), 60 patients with systemic sclerosis (SSc), 29 patients with fibromyalgia (FM), 50 patients with osteoarthritis (OA) and 68 healthy individuals as controls. IL-29 levels in serum were investigated by ELISA. Sensitivity, specificity and likelihood ratios (LR) for having RA were calculated. RESULTS Serum levels of IL-29 were increased in RA patients 113.6 (IQR = 31.25-308.5) pg/ml compared to non-RA patients (SLE, SSc, OA, and FM) (31.25 pg/ml) and healthy controls (31.25 pg/ml, p < 0.001). The IL-29 cut-off values to distinguish patients with RA from non-RA patients were 61.11 pg/ml (sensitivity 57.02, specificity 92.71, LR: 7.82) and for all subjects 32.96 pg/ml (sensitivity 64.46, specificity 87.31, LR: 5.08). Additionally, IL-29 correlated negatively with age (r=-0189, p = 0.038) and disease duration (-0.192, p = 0.037). Interestingly, IL-29 correlated positively with neutrophil count in RA patients positive for rheumatoid factor (r = 0.259, p = 0.022). CONCLUSION IL-29 is higher in the serum of patients with RA compared to non-RA subjects and may have potential for use as a biological marker.

Abstract
Systemic lupus erythematosus (SLE) is a complex autoimmune disorder involving heterogeneous clinical manifestations and numerous susceptibility genes. Several findings evidence the critical role of inflammasomes in the predisposition to autoimmune diseases and in SLE. We investigated whether inflammasome polymorphins could affect susceptibility to develop and/or severity SLE. Moreover, differences in inflammasome activation in peripheral blood were also evaluated in SLE patients and controls. The distribution of 13 SNPs in eight inflammasome genes was evaluated. To assess inflammasome priming in peripheral blood monocytes of SLE and controls, differential expression of selected inflammasome genes and IL-1ß production was analyzed in resting condition as well as after LPS and ATP stimulation. Results showed that the gain-of-function variant rs10754558 (NLRP3) was significantly more frequent in SLE patients with nephritis, reinforcing the concept of a key role of NLRP3 inflammasome not only in SLE but also especially in kidney disease. SLE monocytes in resting condition showed a higher level of IL-1ß expression and produced higher levels of IL-1ß when stimulated with LPS+ATP comparing to controls. The stimulation induced a significant expression of NLRP1, AIM2, CASP1, and IL1B genes, suggesting that the NLRP1 inflammasome is responsible for the IL-1ß production observed in monocytes. These data emphasized once more the important contribution of inflammasome in SLE-associated inflammation.

Abstract
Although several cytokines and chemokines have been investigated as possible mediators of fibrosis in systemic sclerosis (SSc), specific correlation between cytokines and organ involvement have not been found yet, and a cytokine profile characteristic of SSc is far to be identified. We studied the profile of antifibrotic and profibrotic transcripts involved in skin of SSc patients. The mRNA expression was detected by fluorescence-based quantitative real-time PCR (qPCR) in skin's biopsies from 14 patients with SSc and 5 healthy controls. PDGF-A, CTGF, CCL3, IL-6, IL-13, IL-7, IFNγ, IL-17, IL-22 and RORc were analysed in these samples. CCL3, IL-7, IL-13 and IFN-γ were more expressed in skin's biopsy of patients with SSc (P = 0.0002, P = 0.0082, P = 0.0243, P = 0.0335, respectively) when compared with healthy controls. We also found a positive correlation between CCL3 and IL-7 transcripts (P = 0.0050 r = 0.7187). Furthermore, we observed that patients with lung involvement had lower expression of PDGF-A (P = 0.0385). We found an increase in IL-7, IFN-γ, CCL3 and IL-13 relative mRNA expressions on the skin's biopsy of patients with SSc, and a positive correlation between IL-7 and CCL3. These molecules are involved in the pathogenesis of SSc, and how their interactions occur should be the subject of further studies.

Abstract
Glucocorticoids (GC) are widely used in the treatment of SSc, although there is not much evidence to prove the benefits offered by these drugs in this disease. In this study, we evaluated the effects of a GC on cytokine production in peripheral blood mononuclear cells (PBMC) of SSc patients. The effect of dexamethasone (DEX) was evaluated in PBMC of 21 SSc patients and 10 healthy volunteers after stimulation of cells with anti-CD3 and anti-CD28. Cytokines IL-2, IL-4, IL-6, IL-10, IL-17A, IL-17F, IFN-γ, TNF, and IL-1β were quantified in the culture supernatant by CBA or ELISA. Of the patients evaluated in this study, 8 (38%) were taking corticosteroids, and esophageal dysfunction was more frequent in these patients when compared to those who did not take corticosteroids. DEX (1.000 nM) treatment in PBMC of SSc patients stimulated with anti-CD3 and anti-CD28 promoted a significant reduction in IL-2, IL-4, IL-6, IL-10, IL-17A, IFN-γ, TNF, IL-1β (p < 0.001 for all), and IL-17F (p = 0.023) cytokines levels. We did not observe differences in response to in vitro treatment with DEX between groups of patients taking or not taking corticosteroids. In PBMC from healthy volunteers, we observed that DEX treatment significantly reduced IL-4, IFN-γ (p = 0.003 for both), IL-6, IL-10, IL-17A, and TNF (p = 0.002 for all) cytokines. These results show that DEX treatment in PBMC of SSc patients reduced the production of important cytokines involved in the pathogenesis of the disease, suggesting a possible mechanism of action of the CG in the treatment of SSc.

Abstract
Systemic sclerosis (SSc) is a multisystemic, complex, and rare disease of connective tissue, with high morbidity and mortality, and without specific treatment. The disease is characterized by three main principles: vascular disease, autoantibody production and inflammation, and fibrosis. Since it is well defined that SSc is characterized by elevated production of TGF-β, IL-6, and IL-1, all of them cytokines related to Th17 differentiation, the hypothesis is that this disease may be strongly related to a polarization of the immune response towards the Th17 pathway. Considering the importance of a better understanding of the pathophysiology of Th17 pathway in SSc, this article aims to propose an update for a better understanding of current knowledge on main cytokines secreted by the Th17 cells (IL-17 A, IL-21, and IL-22) and the future prospects in the current disease.

Abstract
In this study, we evaluated glucocorticoids (GC) effects on cytokine/chemokine levels in serum samples and peripheral blood mononuclear cell (PBMC) production from systemic sclerosis (SSc) patients. We evaluated cytokine and chemokine levels in serum samples from SSc patients taking or not taking systemic glucocorticoids. PBMCs response to methylprednisolone (MP) was examined from 15 SSc patients and 8 healthy control subjects following PBMC stimulation with anti-CD3/CD28. Cytokine (IFN-γ, TNF, IL-2, IL-4, IL-6, IL-10, and IL-17A) and chemokine (CXCL8/IL-8, CCL5/RANTES, CXCL9/MIG, CCL2/MCP-1, and CXCL10/IP-10) levels were quantified in serum and in PBMC culture supernatants by CBA or ELISA. Compared with patients not taking corticosteroids, we did not observe any significant differences in cytokines/chemokines serum levels in patients using systemic corticosteroids. After stimulation with anti-CD3/CD28, PBMCs treated with MP (100μM), showed a significant reduction of CCL2/MCP-1 (p=0.001), CCL5/RANTES (p=0.04), and CXCL8/IL-8 (p=0.003) levels in SSc patients. In PBMC from healthy controls, we observed decreased IFN-γ, TNF, IL-2, and IL-10 levels after MP treatment, compared with stimulated condition (p<0.01 for all). However in SSc patients, we did not find any significant reduction in these cytokine levels after MP treatment. In conclusion, CCL2/MCP-1, CCL5/RANTES, and CXCL8/IL-8 are chemokines that are potentially modulated by corticosteroids in vitro in SSc patients, but no effect was observed on IL-2, IL-4, IL-6, IL-10, IL-17A, TFN, and IFN-γ secretion. These results suggest a potential effect of GCs on SSc treatment and may reflect the benefit of their use in some patients.

Abstract
BACKGROUND Interferon (IFN)-λ1 is a newly described cytokine, member of type III interferons family, which is known for its antiviral, anti-proliferative and antitumor activity. Recent studies indicated that this cytokine has also immune-regulatory function, but its role in the pathogenesis of autoimmune diseases is not established yet. We evaluated serum levels of IFN-λ1 in systemic sclerosis (SSc) patients and healthy controls and its association with IFN-γ and clinical manifestations. METHODS IFN-λ1 and IFN-γ serum levels were measured by ELISA from 52 patients with SSc and 53 healthy controls. Association of cytokines serum levels was sought with clinical parameters. RESULTS IFN-λ1 and IFN-γ levels in SSc patients were significantly higher than those in healthy individuals (24.82 ± 8.78 and 11.04 ± 3.04 pg/ml, p < 0.0001; 34.11 ± 8.11 and 10.73 ± 2.77 pg/ml, p < 0.0001, respectively). We found a positive correlation between IFN-λ1 and IFN-γ levels in SSc patients (p = 0.0103, r = 0.3526). IFN-γ levels were associated with muscle involvement (p = 0.0483). CONCLUSION We first showed raised IFN-λ1 levels in SSc patients. Furthermore, we found a correlation between IFN-λ1 and IFN-γ levels and an association between IFN-γ and myositis. Additional in vitro and in vivo studies are needed to understand IFN-λ1 role in SSc.

Abstract
The immunological role of interleukin 27 has been reported in various inflammatory diseases, but its importance in systemic lupus erythematosus pathogenesis is not completely established. The aim of this study was to evaluate serum levels of IL-27 in SLE patients and its correlation with clinical manifestations and disease activity. IL-27 levels were assessed in 70 SLE patients and 30 healthy controls by ELISA. Clinical and laboratory parameters were recorded. Statistic analyzes were performed by Graph Prism 3.02 software. The IL-27 serum levels were significantly decreased in SLE patients compared with controls (mean 899.92 and 1,531.22 pg/ml, P=0.0005). There was a correlation between IL-27 levels and C3 levels (P=0.004). Nevertheless, there was no association of serum IL-27 levels with disease activity evaluated by SLEDAI score (P=0.9605). No significant difference was found regarding IL-27 levels between SLE patients with and without nephritis, haematuria, proteinuria and positive anti-dsDNA. Correlation analysis between serum IL-27 levels and SLEDAI, SLICC, proteinuria levels, C4 and CH50 levels also showed no association. These data demonstrated decreased serum levels of IL-27 in SLE patients but further studies are needed to clarify the precise role of this cytokine and its potential use as therapeutic target.

Abstract
OBJECTIVE To analyze the role of interleukin 22 (IL-22) in rheumatoid arthritis (RA). METHODS IL-22 serum levels were measured in 83 patients with established RA under treatment with disease-modifying antirheumatic drugs and in 30 healthy controls matched for age and sex. Patients were assessed for clinical and laboratory variables. Correlations of IL-22 serum levels with disease activity measures [Clinical Disease Activity Index (CDAI) and Disease Activity Score for 28 joints (DAS28)], serological markers, bone erosions, and demographic factors were assessed. Peripheral blood mononuclear cells (PBMC) from 30 patients with RA and 14 controls were purified and stimulated in vitro with phorbol myristate acetate (PMA)/ionomycin. IL-22 production by PBMC and in serum was investigated by ELISA. RESULTS IL-22 levels were increased in patients with RA compared with controls (mean 432.37 pg/ml and 67.45 pg/ml, respectively; p < 0.001). Levels of IL-22 correlated with DAS28 and CDAI measures. Rheumatoid factor (RF) positivity was correlated with higher levels of IL-22 in patients with RA (mean 575.08 pg/ml; p = 0.001). The presence of bone erosions was associated with high IL-22 levels (p = 0.0001). PBMC stimulated with PMA/ionomycin expressed higher levels of IL-22 in patients with RA than controls but this was not significant (mean 584.75 pg/ml and 295.57 pg/ml; p = 0.553). CONCLUSION IL-22 is elevated in the serum of patients with established RA. Elevated serum IL-22 allows discrimination between patients with different clinical and laboratory measures and indicates the potential of IL-22 as an additional tool for assessment of activity in RA, particularly in patients with RF antibodies and longterm disease. IL-22 is associated with bone-destructive disease.

Abstract
In addition to its role in calcium homeostasis, it is believed that the active form of vitamin D has immunomodulatory effects on cells of the immune system, particularly T lymphocytes, as well as on the production and action of several cytokines. The interaction of vitamin D with the immune system has been the target of a growing number of publications in recent years. Current studies have linked the deficiency of vitamin D with different autoimmune diseases, including insulin-dependent diabetes mellitus (IDDM), multiple sclerosis (MS), inflammatory bowel disease (IBD), systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA). This article reviews the physiology and immunomodulatory role of vitamin D, emphasizing its involvement in rheumatic diseases such as SLE and RA.

Abstract
A cohort of cases initiating tuberculosis treatment from May 2001 to July 2003 was followed in Recife, Pernambuco State, Brazil, to investigate biological, clinical, social, lifestyle, and healthcare access factors associated with three negative tuberculosis treatment outcomes (treatment failure, dropout, and death) separately and as a group. Treatment failure was associated with treatment delay, illiteracy, and alcohol consumption. Factors associated with dropout were age, prior TB treatment, and illiteracy. Death was associated with age, treatment delay, HIV co-infection, and head of family's income. Main factors associated with negative treatment outcomes as a whole were age, HIV co-infection, illiteracy, alcoholism, and prior TB treatment. We suggest the following strategies to increase cure rates: further training of the Family Health Program personnel in TB control, awareness-raising on the need to tailor their activities to special care for cases (e.g., literacy training); targeting use of directly observed therapy for higher risk groups; establishment of a flexible referral scheme to handle technical and psychosocial problems, including alcoholism; and increased collaboration with the HIV/AIDS program.
