Background:Access to assays of circulating anti-Mullerian hormone (AMH) levels has opened a new page in the assessment of ovarian function and fertility in various diseases, including rheumatic diseases (RDs). The definition of AMH as a marker of ovarian reserve significantly simplified its interpretation as well as measuring the contribution of the disease itself to the patients’ infertility.Objectives:To evaluate the effects of the disease and it’s treatment on serum AMH levels for Behcet’s disease (BD), systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and systemic scleroderma (SSD).Methods:The study included 73 patients with RDs from 18 to 40 years: 42 patients with BD, 12 with SLE, 11 with RA, 8- with SSD, the control group consisted of 15 healthy women. Enzyme-linked immunosorbent assay (ELISA) was used to measure AMH levels. Parametric and nonparametric statistical methods of Statistica 8.0 package were used for statistical processing of data.Results:Mean age in BD patients was 30.0 years, in SLE and RA -33.5 years, in SSD - 35.0 years, and 32.0 years in the control group. The average disease duration was 4.5 years, 11.5 years, 4.0 years and 6.0 years, respectively.BD, n=42SLE, n=12RA, n=11SSD, n=8Control, n=15Mean age, years30,0[26;35]33.5[29;38]33,5[24;36]35,0[28;40]32,0[26;35]Average disease duration, years4,5[2,6;9,0]11,5[2,8;18]4,0[4,0;6,0]6,0[2,0-10,0]-Mean AMH level, ng/ml2,5[1,1;3,7]3,5[0,4-7,1]3,35[2,0;7,6]2,5 [0,3;7,1]3,1[1,9;5,4]There were no significant differences in the mean AMH levels between the groups. No association between AMG levels and clinical manifestations, disease activity or duration of rheumatic disease was found. Baseline AMH – in treatment-naïve patients before initiation of any DMARDs was assessed in 11 BD patients. A significant (p>0.05) decrease of AMH levels was established in patients with high SLE activity treated with CP. Of notice, all examined patients were additionally receiving a GEBD -Rituximab.Conclusion:Decreased ovarian function was found in patients with high SLE activity treated with CP with Rituximab.Disclosure of Interests:None declared

Objective: to study risk factors for invasive aspergillosis (IA), its etiology, clinical manifestations, and treatment efficiency in patients with rheumatic diseases (RD).Patients and methods. The first study of proven and probable IA (EORT/MSGERC, 2019) was conducted in 18 patients with RD, who accounted for 3% of all adult IA patients (n=699) included in the 1998–2020 registry of the Department of Clinical Mycology, Allergology, and Immunology, I.I. Mechnikov North-Western State Medical University (Group 1). This group comprised 56% women; the median age was 59 [21; 75] years. Group 2 (a comparison group) included 610 adult hematology patients with IA (median age, 45 [18; 79] years; 42% women). A prospective case-control study was conducted to identify risk factors for IA in patients with RD: 36 rheumatic patients without IA (median age, 58 (18–79) years; 61% women) (a control group).Results and discussion. Patients with RD were found to often develop IA in the presence of anti-neutrophilic cytoplasmic antibody-associated vasculitis (granulomatosis with polyangiitis and microscopic polyangiitis) and systemic lupus erythematosus (50 and 16%, respectively). It was shown for the first time that the likelihood of IA in patients with RD increases with prolonged (median 14 days) lymphocytopenia during RD treatment (odds ratio 13.0; 95% confidence interval, 3.3–50.3). The main causative agents of IA were A. fumigatus (50%) and A. niger (29%). IA was more severe in Group 1 than in Group 2: in the resuscitation and intensive care units, there were 44 and 18%, respectively (p=0.01). Group 1 versus Group 2 more frequently had respiratory failure (61 and 37%, respectively; p=0.03), hemoptysis (28 and 7%; p=0.0001), chest pain (17 and 7%; p=0.04), and cardiac involvement (11 and 1%; p=0.0001), and less frequently had fever (67 and 85%; p=0.01). The common site of IA was the lung (83%); the characteristic feature detected by computed tomography (CT) is pulmonary cavitation (44%). Antifungal therapy was used in 89% of Group 1 patients; the overall 12-week survival was 69%.Conclusion. In patients with RD, it is difficult to differentiate between the progression of the underlying disease, adverse drug reactions, infectious complications, or a combination of these disorders due to the similarity of their clinical manifestations. When RD patients with infectious syndrome and respiratory failure develop prolonged lymphocytopenia during combination therapy, AI should be suspected and lung CT, bronchoscopy, and mycological examination of the material obtained by bronchoalveolar lavage be done.

Background:Lupus nephritis is the most severe and adverse systemic lupus erythematosus (SLE) syndrome. According to modern recommendations, the clinical manifestations of active nephritis should be taken under medical control in 6 months after the start of the disease’s treatment1.Objectives:The aim of this study was to examine the functional status of the kidneys in children with SLE in the course of the disease for more than one year.Methods:The analysis included case histories of 43 patients with SLE, mostly females (41), aged 7 to 18 years (mean age 14.4 years) with disease duration of 4.75 ± 0.58 years of whom 22 were less than three years, 21 - more than three years. All children received corticosteroid therapy, at the time of the examination the average dose was 13.85 ± 1.86 mg per day in terms of prednisolone. The second component of therapy was azathioprine (average dose 97.61 ± 2.11 mg). All children received hydroxychloroquine (5 mg/kg per day).To determine the functional state of the kidneys a clinical analysis of urine, a study of the scope of specific gravity of urine during the day (Zymnytsky test), the content of creatinine and urea in serum to determine the glomerular filtration rate (GFR), the level of microalbuminuria per day were evaluated.Results:Renal involvement in the developed SLE occurred in 73.08% of patients. Among them, therapy during the first 6 months was considered quite effective in 58.06% of patients. It was found that in children with disease duration from one to three years proteinuria was registered in 68.18%, a decrease in GFR in 4.45% and hyperfiltration in 9.09%. In the group of children with duration of SLE more than three years revealed deeper changes in renal function; there was proteinuria in 90.47%, the frequency of GFR decreased was in 19.04%, a decrease of renal concentration function was in 14.28% of cases.Indicators of renal function in children with SLE depending on the duration of the disease (M ± m)IndicatorDuration of the diseasefrom 1 year to 3 years n = 22over 3 yearsn = 21Creatinine, mmol/l0,080 ± 0,0140,090 ± 0,018Мочевина, mmol/l5,66 ± 1,425,63 ± 1,61GFR, ml/min117,05 ± 19,68100,20 ± 18,98 *Microalbuminuria, mg/day24,41 ± 13,1334,73 ± 24,76Density min1,007 ± 0,0051,006 ± 0,005Density max1,024 ± 0,0051,019 ± 0,005 ***р<0,03;**р<0,01 the probability of differences when comparing between groupsConclusion:Long-term follow-up of children with SLE over one year reveals a prolongation of renal dysfunction, which worsens after three years, and is the basis for the development of irreversible renal impairment.References:[1]European evidence-based recommendations for the diagnosis and treatment of childhood-onset lupus nephritis: the SHARE initiative /Noortje Groot, Nienke de Graeff, Stephen D Marks et all. //Ann Rheum Dis. 2017 Dec;76(12):1965-1973.Disclosure of Interests:None declared

Heart Rate Turbulence

Background Systemic lupus erythematosus is a progressive autoimmune disease. There are reports suggesting that patients even without overt signs of cardiovascular complications have impaired autonomic function. The aim of this study was to assess autonomic function using heart rate turbulence and heart rate variability parameters indicated in 24-hour ECG Holter monitoring. Methods Twenty-six women with systemic lupus erythematosus and 30 healthy women were included. Twenty-four hour ambulatory ECG-Holter was performed in home conditions. The basic parameters of heart rate turbulence and heart rate variability were calculated. The analyses were performed for the entire day and separately for daytime activity and night time rest. Results There were no statistically significant differences in the basic anthropometric parameters. The mean duration of disease was 11.52 ± 7.42. There was a statistically significant higher turbulence onset (To) value in patients with systemic lupus erythematosus, median To = –0.17% (minimum –1.47, maximum 3.0) versus To = –1.36% (minimum –4.53, maximum –0.41), P < 0.001. There were no such differences for turbulence slope (Ts). In the 24-hour analysis almost all heart rate variability parameters were significantly lower in the systemic lupus erythematosus group than in the healthy controls, including SDANN and r-MSSD and p50NN. Concerning the morning activity and night resting periods, the results were similar as for the whole day. In the control group, higher values in morning activity were noted for parameters that characterise sympathetic activity, especially SDANN, and were significantly lower for parasympathetic parameters, including r-MSSD and p50NN, which prevailed at night. There were no statistically significant changes for systemic lupus erythematosus patients for p50NN and low and very low frequency. There was a positive correlation between disease duration and SDNN, R = 0.417; P < 0.05 and SDANN, R = 0.464; P < 0.05, a negative correlation between low/high frequency ratio and r-MSSD, R = –0.454; P < 0.05; p50NN, R = –0.435; P < 0.05 and high frequency, R = –0.478; P < 0.05. In contrast, there was no statistically significant correlation between heart rate turbulence and other variables evaluated, including disease duration and the type of autoantibodies. Conclusion: Our study confirms the presence of autonomic disorders with respect to both heart rate variability and heart rate turbulence parameters and the presence of diurnal disturbances of sympathetic–parasympathetic balance. Further studies are required.

Abstract Background The host inflammatory response against infection is characterized by leukocytosis, and the release of cytokines and acute phase proteins. However, routine inflammatory markers are not always elevated in systemic rheumatic diseases (SRD). Here, we aimed to systematically evaluate and compare the clinical implications of common inflammatory markers in systemic rheumatic diseases (SRDs). Methods We investigated the profiles of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and white blood cell (WBC) count in treatment-naïve patients with SRDs, osteoarthritis and pneumonia diagnosed at Seoul National University Hospital during 2004-2016. SRDs included rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), systemic sclerosis (SSc), idiopathic inflammatory myopathy (IIM) and adult onset of Still disease (AOSD). Associations between inflammatory markers were evaluated using Pearson’s correlation and regression analysis. Differences between correlations were compared using Steiger’s z-test. Receiver operating characteristic (ROC) curve analysis was performed to examine the predictive value of inflammatory markers for SRD diagnosis. Results We identified 1191 patients with SRDs, osteoarthritis and pneumonia. Leukocytosis was present in <15% SRD patients. There was marked variability in ESR and CRP levels among different SRDs. The highest mean CRP levels (mean ± SD, mg/dL) were observed in those with AOSD (11.3±7.9), followed by RA (2.0±3.3), IIM (1.8±3.5), SLE (1.5±3.1), SSc (0.6±1.3) and AS (0.08±0.1). Mean ESR (mm/hr) was also highest in AOSD (71.2±31.0), followed by SLE (47.3±34.2), RA (45.5±30.6), IIM (40.8±24.8) and SSc (27.8±26.0). All SRDs showed significant positive correlations between ESR and CRP: greatest in RA (r=0.53, p<0.001) and weakest in SLE (r=0.20, p=0.03). WBC correlated weakly with CRP but not with ESR in most SRDs. While the AUC for WBC count (0.54-0.68) was less than that of ESR or CRP, the AUC for ESR and CRP (0.69-0.86) were similar in SRD. The optimal cuff-off values for inflammatory markers predicting SRD were within or slightly above the normal limit. Conclusions Unlike acute infection, ESR, CRP and WBC count are not always elevated in treatment-naïve patients with SRD. Thus, common inflammatory markers have limited value for diagnosis and assessment of disease activity of SRD.

Background The concomitant presence of two autoimmune diseases – systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) – in the same patient is known as rhupus. We evaluated a group of patients with rhupus to clarify further their clinical, serological and immunogenic features in a multi-centre cohort. In addition, the study aimed to explore the utility of the 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) SLE classification criteria in our group of patients with rhupus. Methods This was a cross-sectional study. We included rhupus patients from 11 different rheumatology departments, and compared them to SLE and RA patients at a ratio of 2:1. All information was recorded following a pre-established protocol. Results A total of 200 patients were included: 40 rhupus patients and 80 each of SLE and RA patients as controls. Disease duration was similar among SLE and rhupus groups (around 13 years), but the RA group had a significantly lower disease duration. Main clinical manifestations were articular (94.2%), cutaneous (77.5%) and haematological (72.5%). Rhupus patients had articular manifestations similar to those expected in RA. Only 10% of rhupus patients had renal involvement compared with 25% of those with SLE ( p < 0.05), while interstitial lung disease was more common in patients affected by RA. The 2019 EULAR/ACR SLE criteria were met in 92.5% of the rhupus patients and in 96.3% of the SLE cohort ( p > 0.05). Excluding the joint domain, there were no differences between the numbers of patients who met the classification criteria. Conclusion Rhupus patients follow a particular clinical course, with full expression of both SLE and RA in terms of organ involvement, except for a lower prevalence of kidney affection. The new 2019 EULAR/ACR SLE criteria are not useful for differentiating SLE and rhupus patients. A new way of classifying autoimmune diseases is needed to identify overlapping clusters.

Background: The purpose of our study was to assess the diagnostic power of galectin-3 and compare its between rheumatic diseases and with routinely used tests such as CRP and ESR. Methods: Eighty-two patients with rheumatoid arthritis (RA), 49 patients with systemic sclerosis (SSc), and 18 patients with systemic lupus erythematosus (SLE) were enrolled in this study. The control group comprised 30 healthy controls. Serum galectin-3 concentration was measured using immunochemical method. Results: The galectin-3 concentration were significantly elevated in the RA, SSc, and SLE in comparison to the controls (p = 0.000, p = 0.000, p < 0.001; respectively). However, there were no significant differences in the serum galectin-3 levels between rheumatic diseases (H = 0.395, p = 0.821). In RA and SSc patients, galectin-3 positively correlated with erythrocyte sedimentation rate (R = 0.332, p = 0.004; R = 0.384, p = 0.009; respectively). ROC analysis revealed that galectin-3 had an excellent diagnostic power in RA (AUC = 0.911) and SSc (AUC = 0.903) and very good for SLE (AUC = 0.859). Conclusion: We concluded that diagnostic power of serum galectin-3 is as great as CRP and ESR in rheumatic diseases and it can be a very good laboratory marker in RA and SSc patients and a useful tool in the diagnosis of SLE.

Background: Anti-nuclear antibodies (ANAs) are specific antibodies directed against a variety of nuclear antigens detected in the serum of patients with many rheumatic and non-rheumatic diseases.These antibodies are not only involved in the pathogenesis, but also constitute the basis for diagnosis and treatment of paediatric rheumatic diseases. The objective of the study was to identify the patterns and frequency of ANA positivity in Paediatric Rheumatic Diseases. Methodology: It was a retrospective study. Fourteen hundred and sixty eight records of paediaric rheumatology patients were analyzed. Statistical analysis were done to observe the frequency and association of different patterns of ANA in Juvenile idiopathic arthritis and systemic lupus erythematosus patients. Results: Among the 1468 patients of PRDs, frequency of JIA cases was the highest (65 %) followed by SLE, Scleroderma, juvenile dermatomyositis, and others. Among the 261 PRD patients ANA positivity was 65%. ANA positivity was 100%, 92%, 40% and 31.5% in Mixed connective tissue disease, SLE, JDM and Scleroderma patients respectively. Homogenous staining pattern was found in 59% and speckled pattern in 22.9%. There was significant association between ANA positivity and uveitis in oligoarticular JIA patients. Significant association was also found between homogeneous patterns of ANA and renal involvement in SLE patients. Conclusion: ANA positivity was highest in MCTD cases followed by SLE cases. Majority of SLE cases had homogeneous pattern of ANA.Staining patterns of ANA had significant association with the clinical manifestations in SLE and JIA cases.

AbstractPrimary gonadal failure may occur in most individuals with Turner syndrome (TS). Since ovaries in TS girls undergo premature apoptosis and cryopreservation of ovarian tissue is now feasible, it would be useful to identify a reliable marker of ovarian reserve in these patients. We planned to evaluate ovarian function in a group of TS patients by measuring both traditional markers and inhibin B and to compare these results with those of a control group.We enrolled 23 patients with TS and 17 age-matched healthy girls. The median age of our TS patients was 17.6 years. Three out of the 23 patients (13%) showed spontaneous pubertal development and regular menstrual cycles; the remaining 20 (86.9%) presented with primary amenorrhea.The median level of inhibin B in the TS patients with primary amenorrhea was 42 pg/mL and did not differ significantly among the different subgroups in relation to karyotype. The median inhibin B level in the control group was significantly higher than in the TS girls with primary amenorrhea (83 vs. 42 pg/mL, p<0.00001). In the three patients with TS and spontaneous menstrual cycles, the inhibin B levels were significantly higher when compared to the values of the TS girls with primary amenorrhea.TS patients with primary amenorrhea have significantly lower levels of inhibin B than TS girls with spontaneous puberty and healthy controls. Inhibin B does not correlate with follicle-stimulating hormone/luteinizing hormone. If our results are confirmed in further studies, inhibin B could become a first-line screening test for assessing ovarian reserve and a longitudinal marker of the possible decline of ovarian function in TS.

Objective.Type I interferons (IFN), especially IFN-α, have been proposed to underlie the pathogenesis of systemic lupus erythematosus (SLE). Members of the IFN regulatory factor (IRF) family, which regulate IFN expression, have been implicated as risk factors for SLE. Our aims were to investigate the expression of IRF7 and its correlation with disease activity and to explore the association in Taiwanese patients between 2 genetic single-nucleotide polymorphisms (SNP) of IRF7 and SLE.Methods.IRF7 messenger RNA (mRNA) levels were measured in peripheral blood mononuclear cells by real-time reverse transcription polymerase chain reaction in 51 adult patients with SLE and 65 age-matched and sex-matched controls. Their serum IFN-α levels were determined by ELISA and the clinical manifestations were recorded at the same time. Two IRF7 SNP, rs1061501 and rs1061502, were examined by genotyping across 92 patients with SLE and 92 age and sex-matched healthy control subjects.Results.Compared with controls, the expression of IRF7 mRNA was significantly increased in patients with SLE and was positively correlated with both the serum level of IFN-α and lupus disease activity. The distribution of SNP rs1061501 by genotype (CC, CT, and TT) and by allele (C, T) was significantly different between the SLE and the control group (p = 0.028 for genotype and p = 0.009 for allele). There were no significant differences for SNP rs1061502.Conclusion.The results suggest that dysregulation of IRF7 might mediate an excessive production of IFN-α, which then exerts a crucial effect on the pathogenesis of human SLE. The IRF7 SNP rs1061501 TT genotype and T allele are enriched in Taiwanese patients with SLE and thus would seem to be associated with an increased risk of developing SLE.

Active Disease

Systemic lupus erythematosus (SLE) is an inflammatory rheumatic disease characterized by production of autoantibodies and organ damage. Elevated levels of cytokines have been reported in SLE patients. In this study we have investigated the effect of proinflammatory cytokines (IL-6, TNF-α, and IL-1β) on clinical manifestations in 145 Indian SLE patients. One hundred and forty-five healthy controls of the same ethnicity served as a control group. Clinical disease activity was scored according to SLEDAI score. Accordingly, 110 patients had active disease and 35 patients had inactive disease. Mean levels of IL-6, TNF-α, and IL-1βwere found to be significantly higher in SLE patients than healthy controls (P<0.001). Mean level of IL-6 for patients with active disease (70.45±68.32 pg/mL) was significantly higher (P=0.0430) than those of inactive disease patients (43.85±63.36 pg/mL). Mean level of TNF-αwas44.76±68.32 pg/mL for patients with active disease while it was25.97±22.03 pg/mL for those with inactive disease and this difference was statistically significant (P=0.0161). Similar results were obtained for IL-1β(P=0.0002). Correlation between IL-6, TNF-α, and IL-1βserum levels and SLEDAI score was observed (r=0.20,r=0.27, andr=0.38, resp.). This study supports the role of these proinflammatory cytokines as inflammatory mediators in active stage of disease.
