This study was aimed to evaluate serum KL-6 levels to determine if this marker can be used for diagnosing and assessing severity of interstitial lung disease (ILD) in children with connective tissue disorders. In total, 40 patients [18 patients with juvenile systemic lupus erythematosus (JSLE), 10 patients with juvenile idiopathic arthritis (JIA), 8 patients with juvenile mixed connective tissue disease (JMCTD), 3 patients with juvenile systemic sclerosis (JSSc), and 1 patient with juvenile dermatomyositis (JDM)] and 20 healthy controls were included in this study. Age, sex, and duration of CTD and ILD (if any) were recorded. Blood samples from all the patients and controls were examined by ELISA. 20 of the 40 patients with CTD (50%) had ILD, 12 were mild and 8 were severe as assessed by spirometry. The median serum KL-6 level was 102.7 U/mL (76.1-180.8) in the CTD with severe ILD group, 72.2 U/mL (58.4- 100.5) in the CTD with mild ILD group, 56.7 U/mL (35.8-68.5) in the CTD without ILD group, and 52.3 U/mL (32.8-62.4) in the control group. KL-6 levels were significantly higher in the CTD with ILD (p<0.05), at a cutoff of 63.4 U/ml identified by ROC curve, serum KL-6 showed a sensitivity of 95.2% and specificity of 89.7%. KL-6 is a valuable biomarker for diagnostic purposes and to detect severity in ILD in childhood CTD.

Mixed connective tissue disease (MCTD) is a rare disorder characterized by symptoms that overlap two or more Autoimmune Connective Tissue Diseases (ACTDs). The aim of this study was to determine whether miRNAs participating in the TLRs signaling pathway could serve as biomarkers differentiating MCTD or other ACTD entities from a healthy control group and between groups of patients. Although the selected miRNA expression level was not significantly different between MCTD and control, we observed that miR-126 distinguishes MCTD patients from all other ACTD groups. The expression level of miRNAs was significantly higher in the serum of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) patients compared to controls. The miR-145 and -181a levels distinguished RA from other ACDT patients. miR-155 was specific for SLE patients. MiR-132, miR-143, and miR-29a distinguished RA and SLE patients from the systemic sclerosis (SSc) group. Additionally, some clinical parameters were significantly related to the miRNA expression profile in the SLE group. SLE and RA are characterized by a specific serum expression profile of the microRNAs associated with the Toll-like receptors (TLRs) signaling pathway. The analysis showed that their level distinguishes these groups from the control and from other ACTD patients. The present study did not reveal a good biomarker for MCTD patients.

The performance of immunoassays for the detection of autoantibodies is of critical importance in the diagnosis and assessment of patients with autoimmune connective tissue diseases (ACTD). Our objective was to compare the features of two multiplexed assays—INNO-LIA ANA and Gennova-PictArray ENA ELISA—for measurement of multiple autoantibodies and their utility as a clinical tool in ACTD diagnosis. The antigens included SS-A/Ro (60 and 52), SSB/La, Sm, Sm/RNP, CENP-B, Jo-1, and Scl-70. Stored sera from 85 ACTD patients and 80 controls consisting of patients with vasculitis, rheumatoid arthritis and infectious diseases, as well as healthy subjects were analyzed jointly with clinical and laboratory data. Agreement between the two methods varied between 58 and 99% (Cohen’s kappa: 0.21–0.71) mostly for SSA and SSB. The frequency of specific autoantibodies measured using the two methods was more variable for SSA, SSB, and RNP/Sm. There were a higher number of ambiguous results when using INNO-LIA. The optimized cut-off values of the Gennova-PictArray resulted in over 99% specificities in samples obtained from the control group. Sensitivity patterns were more accurate in Gennova-PictArray than in INNO-LIA, as suggested in previously reported studies. A third method could be applied to determine which of the two methods is more accurate.

SummaryBackground:The exact role of cytokines in inflammation and metabolic disorders in case of connective tissue diseases (CTDs) is under discussion.Methods:In this study, we intended to find the relationship between the selected cytokines in inflammatory and metabolic disorders in patients with CTDs (n=55) and compared the results with those of control group subjects (n=25) matched by age and body mass. We estimated their nutritional status by the bioimpedance method. The levels of basic biochemical parameters and the levels of adiponectin, resistin, and chemerin were also estimated. Multiple regressions and area under the curve in receiver operating characteristic (AUC–ROC) curve were used to find the associations of aforementioned parameters.Results:Patients with CTDs exhibited higher levels of chemerin than that of control group subjects. We found an inverse relationship between chemerin, RBC count, and hemoglobin levels. The concentration of adiponectin inversely correlated with the levels of platelets and concentrations of glucose and triglycerides as well as the erythrocyte sedimentation rate, whereas the concentration of resistin was positively correlated with WBC count, C-reactive protein (CRP), and the amount of used oral glucocorticosteroids. The mean ± standard deviation for the AUC–ROC curve in case of chemerin was the highest (AUC–ROC=0.714,p=0.0005) than that of both resistin and adiponectin.Conclusions:Chemerin and resistin levels are related to the inflammatory state in patients with CTDs, whereas adiponectin levels seem to be correlated with a protective effect. Chemerin can be considered as a marker differentiating a proinflammatory state present in CTDs.

Introduction. Sarcoidosis, which is a chronic inflammatory granulomatous disease, can mimic different rheumatologic diseases including connective tissue diseases. Antinuclear antibodies are the markers used for connective tissue diseases.Aim. To determine antinuclear antibody frequency and any possible correlation with clinical and laboratory data in sarcoidosis patients.Material and Method. Forty-two sarcoidosis patients, 45 rheumatoid arthritis patients, and 45 healthy volunteers who were followed up in rheumatology outpatient clinic were included in this study. Demographic, clinical, serological, and radiological data of all patients were recorded. Antinuclear antibodies were determined with indirect immunofluorescent method and 1/100 titration was accepted as positive. The cases that were ANA positive were evaluated with immunoblot method.Results. Average age of the 42 patients (10 males) with sarcoidosis was 45.2 (20–70 years), and average disease duration was 3.5 years. ANA positivity was detected in 12 (28.5%) patients with sarcoidosis (1/100 in 10 patients, 1/320 in two patients), in 19 of RA patients (42.2%), and in two of healthy volunteers in low titer (P<0.001). In the subgroup analysis made by immunblot test, one patient had anticentromere antibody, one had anti-Ro antibody, one had anti-Scl-70 antibody, one had anti-dsDNA antibody, and eight patients were negative. The two patients who had anticentromere and anti-Scl-70 antibodies had also Sjögren’s syndrome and scleroderma diagnosis, respectively.Discussion. The prevalence of ANA in patients with sarcoidosis was found to be significantly higher than healthy control group and lower than RA patients. This result shows that ANA may have an important role in the pathogenesis of sarcoidosis and also could be important in revealing the overlap syndromes of sarcoidosis-connective tissue diseases. Further studies with larger series are necessary in this subject.

Background and objectives: The overlap between antineutrophil cytoplasmic antibody (ANCA) associated glomerulonephritis (ANCA-GN) and connective tissue diseases (CTD) has been reported mainly as case series in the literature. Frequency of this association, as well as presentation and outcomes are unknown. Materials and Methods: Patients from the Maine-Anjou ANCA-associated vasculitides (AAV) registry with ANCA-GN diagnosed between 01/01/2000 and 01/01/2018, ANCA positivity, and at least six months of follow-up, were included. Results: 106 out of 142 patients fulfilled the inclusion criteria and were analyzed. CTD was present at ANCA-GN diagnosis in 16 (15.1%) patients. The most common CTD were rheumatoid arthritis, Sjogren syndrome and systemic sclerosis. Compared to the control group, females were more represented in the CTD group (75%, p = 0.001). Renal presentation was comparable between groups, including the pathological analysis of renal biopsies. Patients of CTD group presented a higher rate of non-renal relapse (25% versus 7.7%, p = 0.037), and experienced more frequently a venous thrombotic event (31.2% versus 10%, p = 0.021). No difference between groups was observed according to major outcomes. Conclusion: Association between CTD and ANCA-GN is not a rare condition and predominantly affects females. While AAV presentation is not significantly different, CTD patients experience more frequently non-renal relapse and venous thrombotic events.

Aim. To study the functional state of peripheral and microcirculatory blood flow in patients with pulmonary hypertension associated with systemic connective tissue diseases (PH-SCTD).Material and methods. The study included 22 patients (50,1±14,7) with PH-SCTD I–III functional class. 18 patients had systemic scleroderma, 3 – systemic lupus erythematosus, and 1 patient suffered from rheumatoid arthritis. The control group (CG) comprised 25 healthy volunteers (39,3±10). The studies were performed using finger photoplethysmography (FPG), laser Doppler flowmetry (LDF), and capillaroscopy (CS).Results. According to the FPG data, patients with PH-SCTD relative to CG have lower values of occlusion index in the amplitude of 1,51±0,37 and 2,28±0,46 respectively (<0.05). According to LDF data, signs of venular plethora are observed in patients with PH-SCTD, which is manifested by an increase in the amplitude of respiratory-induced fluctuations in blood flow to 0,17±0,11 (PU) versus 0,13±0,07 (PU) in CG (<0.05), an increase in the constrictor reaction in the cold test was 56,4±16,8 % and 42,1±17,9 % (<0.05) and a venous occlusion test was 56,8±18,7 % and 45,2±17,9 % (<0.05), respectively. According to CS data, patients with PH-SCTD have a noticeable increase in the degree of hydration of the interstitial space, which manifests itself in an increase in the size of the pericapillary space to 160,8±37,3 μm against 114,1±17,4 μm in the CG (<0.00001).Conclusions. In patients with PH-SCTD, all regulatory mechanisms and structural components of microvessels, including endothelial and smooth muscle cells, are involved in the pathological process, which is manifested by an increase in the constrictor activity for all types of stimuli and a violation of the filtration-reabsorption mechanism of metabolism.

The aim - to study and to analyze the indicators of the humoral link of the immune system in patients with systemic connective tissue diseases with chronic activated HSV 1/2 infection and to assess the effect of the revealed disorders on the development of autoimmune pathology. Materials and methods. We examined 380 patients with systemic diseases of the connective tissue (systemic lupus erythematosus, systemic vasculitis, rheumatoid arthritis, psoriasis) with chronic HSV 1/2 infection at the age of 21-67 years. In 45 of them, using the modern molecular genetic diagnosis of herpes simplex, the active phase of chronic HSV 1/2 infection was verified based on the results of the polymerase chain reaction, and in the other 335, the latent phase was verified. The control group consisted of 20 healthy individuals of the appropriate age and gender. In patients with systemic connective tissue diseases with chronic HSV 1/2 infection, the humoral immunity indices were studied: levels of complement component C3 and IFN-a in saliva and blood and acquired: concentration of common major immunoglobulinins: IgG, IgM IgA, IgE; specific IgM and IgG to HSV 1/2; levels of cryoglobulins, cryofibrinogen, CІC in serum. Statistical processing of the results of the study was carried out using generally accepted methods of variation statistics. Results. In patients with systemic diseases of connective tissue with chronic HSV 1/2 infection, activation of the humoral immunity was detected, it was especially evident in the active phase of the infection and was characterized by an increase in the antibody production of specific IgM HSV 1/2 and IgG HSV 1/2, аn increase in the levels of CIC, IgM, IgA and IgE, cryoprecipitation proteins, IFN-a in the blood. In the latent phase of HSV 1/2 infection the levels of IgG production of HSV 1/2, IgE, CEC, cryofibrinogen and cryoglobulins in the blood serum of these patients increased. Conclusions. The presence of chronic activated HSV 1/2 infection in patients with systemic diseases of the connective tissue causes activation of the humoral immunity, creates the conditions for the development of autoimmune processes.

Abstract We examined the effect of phytohemagglutinin (PHA) on glucocorticoid receptors in lymphocytes, using peripheral mononuclear leukocytes from patients with connective tissue diseases. Glucocorticoid receptor concentrations and dissociation constants (Kd) for [3H]dexamethasone binding to lymphocytes from patients with rheumatoid arthritis, Sjögren's syndrome, and other connective tissue diseases did not differ significantly from values for normal volunteers. Kd values correlated positively with glucocorticoid receptor concentrations after PHA stimulation both in normal volunteers and in patients with connective tissue diseases. The correlations (r values) for the control group and patients were not significantly different.
