Safety of esthetic procedures in rheumatic patients: single-center survey of patients.

The popularity of esthetic medicine is growing every year, also among patients with autoimmune inflammatory rheumatic diseases (AIRD). The objective of this study was to evaluate the safety of esthetic medicine (AM) procedures in patients with AIRD. A semi-structured, anonymous questionnaire regarding rheumatic and concomitant diseases and AM procedures was distributed among adult patients hospitalized in the rheumatology department or attending outpatient clinic in the National Institute of Geriatrics, Rheumatology, and Rehabilitation, Warsaw. The main outcome was the occurrence of an adverse event. A number of 512 patients took part in the survey and 15 were excluded (AM procedure preceded the diagnosis of AIRD). The study group consisted of 497 patients, of whom 47 had undergone AM procedures. The procedures performed included: tattooing (22 patients), piercing (16 patients), hyaluronic acid (7 patients), botulinum toxin (5 patients) injections, laser procedures (6 patients), plastic surgery (4 patients), mesotherapy (3 patients) and others. The vast majority of patients had these performed during remission or low disease activity. 70.2% of patients received treatment with disease-modifying antirheumatic drugs (DMARDs) during the AM procedure, with TNF-alfa inhibitors being the most common (63.6%). Adverse events occurred in 15% of patients. All were mild and transient site reactions. Most patients would like to repeat the AM procedure in the future. The use of esthetic medicine procedures in patients with AIRD, including those treated with biologic DMARDs, was associated with a risk of mild site reactions. Most of the patients expressed satisfaction with the results of the AM procedure.

The failure of biological treatment in axial spondyloarthritis is linked to the factors related to increased intestinal permeability and dysbiosis: prospective observational cohort study.

BACKGROUND: A significant number of patients with axial spondyloarthritis (axSpA) do not respond to biological therapy. Therefore, we decided to investigate the specificity of this group of patients and, in particular, whether haptoglobin (Hp), its polymorphism and zonulin, in addition to other clinical features, are predictors of poor response to biological treatment. METHODS: 48 patients with axSpA who were unsuccessfully treated with standard drugs were converted to biological treatment, and from this time on, a 12-week follow-up was started to assess the failure of biological treatment (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) decrease < 2 points). Predictors of treatment failure were identified using logistic regression analysis. RESULTS: 21% of subjects had biological treatment failure. Patients who had a higher zonulin level, a history of frequent infections, were older, had inflammatory bowel disease (IBD), had a lower Hp level at the time of inclusion in biological therapy showed an increased risk of treatment failure. CONCLUSIONS: The results of the study support the hypothesis that the effectiveness of biological treatment of axSpA is limited by changed microbiota and intestinal epithelial barrier dysfunction, as an increased risk of biological treatment failure was observed in patients who were older, had higher zonulin level, IBD and repeated courses of antibiotics due to frequent infections. Therefore, starting biological treatment should be followed by reducing intestinal permeability and regulating the disturbed gut microbiome.

Predictors of treatment failure of non-steroidal anti-inflammatory drugs in patients with axial spondyloarthritis with focus on haptoglobin, haptoglobin polymorphism and zonulin.

According to the Assessment of SpondyloArthritis International Society-European Alliance of Associations for Rheumatology (ASAS-EULAR) recommendations for the management of axial spondyloarthritis (axSpA), patients should undergo at least two courses of non-steroidal anti-inflammatory drugs (NSAIDs) therapy. In our study, we enrolled axSpA patients both at onset and in a flare who had already been treated with NSAIDs ineffectively. Subsequently, according to the recommendations, they received modified NSAID treatment as another attempt to the first-line drug therapy and were monitored from there. We aimed to identify risk factors for treatment failure after 4 weeks (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score ≥ 4) especially amongst zonulin and haptoglobin concentrations, and haptoglobin polymorphism. Treatment failure was observed in 71% of patients, and the following variables were contributed for occurrence of this state: higher zonulin levels, ankylosing spondylitis, X-ray sacroiliitis, magnetic resonance imaging sacroiliitis, long duration of symptoms, high BASDAI, and high value of spinal pain intensity on visual analogue scale. In addition, the following positive correlations were found: haptoglobin concentration with C-reactive protein (r = 0.56; p = 0.0004), and erythrocyte sedimentation rate (r = 0.62; p < 0.0001), as well as between zonulin levels and white blood count (r = 0.5; p = 0.0003). The results of the study presented the identified factors related to the standard treatment failure in axSpA, amongst them zonulin levels. They might be applied to point out the patients for whom the search for a more appropriate method of treatment should be considered.

Revising diagnosis of juvenile idiopathic arthritis in adults: a single-center retrospective study.

The study aimed to assess how many adult patients with juvenile idiopathic arthritis (JIA) treated with biologics fulfill classification criteria for adult rheumatic diseases and to evaluate the course of JIA in adulthood. 138 patients with JIA over 18 years old treated with biologics were included in a cross-sectional observative study. Among 138 adult patients with JIA treated with biologics, 81 patients remained with JIA diagnosis. 57 patients were rediagnosed. 31 patients met the criteria for spondyloarthropathy, among them 18 patients for ankylosing spondylitis, 10 patients for psoriatic arthritis, and 3 patients for non-radiographic axial spondyloarthritis. Rheumatoid arthritis was diagnosed in 24 patients and adults' Still disease in 2 patients. 84 patients of all adults with JIA received one biologic agent, 40 received two biologic agents, and 14 received three or more biologic therapies. 10 patients received biologic agents out of recommendations for JIA. Of the adult JIA patients treated with biologics, 41% met the classification criteria for adult inflammatory diseases. Spondyloarthropathy and rheumatoid arthritis were most commonly diagnosed. Nearly 40% of adult JIA patients required at least one modification of biological treatment. Therefore, it is worth considering a revision of JIA to adult-onset inflammatory disease entities, as it broadens the spectrum of disease-modifying drugs.

Mixed Connective Tissue Disease as Different Entity: Global Methylation Aspect.

Mixed connective tissue disease (MCTD) is a very rare disorder that belongs in the rare and clinically multifactorial groups of diseases. The pathogenesis of MCTD is still unclear. The best understood epigenetic alteration is DNA methylation whose role is to regulate gene expression. In the literature, there are ever-increasing assumptions that DNA methylation can be one of the possible reasons for the development of Autoimmune Connective Tissue Diseases (ACTDs) such as systemic sclerosis (SSc) and systemic lupus erythematosus (SLE). The aim of this study was to define the global DNA methylation changes between MCTD and other ACTDs patients in whole blood samples. The study included 54 MCTD patients, 43 SSc patients, 45 SLE patients, and 43 healthy donors (HC). The global DNA methylation level was measured by ELISA. Although the global DNA methylation was not significantly different between MCTD and control, we observed that hypomethylation distinguishes the MCTD patients from the SSc and SLE patients. The present analysis revealed a statistically significant difference of global methylation between SLE and MCTD (p < 0.001), SLE and HC (p = 0.008), SSc and MCTD (p ≤ 0.001), and SSc and HC (p < 0.001), but neither between MCTD and HC (p = 0.09) nor SSc and SLE (p = 0.08). The highest % of global methylation (median, IQR) has been observed in the group of patients with SLE [0.73 (0.43, 1.22] and SSc [0,91 (0.59, 1.50)], whereas in the MCTD [0.29 (0.20, 0.54)], patients and healthy subjects [0.51 (0.24, 0.70)] were comparable. In addition, our study provided evidence of different levels of global DNA methylation between the SSc subtypes (p = 0.01). Our study showed that patients with limited SSc had a significantly higher global methylation level when compared to diffuse SSc. Our data has shown that the level of global DNA methylation may not be a good diagnostic marker to distinguish MCTD from other ACTDs. Our research provides the groundwork for a more detailed examination of the significance of global DNA methylation as a distinguishing factor in patients with MCTD compared to other ACTDs patients.

Multicenter evaluation of tofacitinib retention and safety in rheumatoid arthritis - why cardiovascular risk factors do not equate to overt risk.

Introduction: This multicenter, real-world, retrospective cohort study aimed to assess the effectiveness and safety of tofacitinib (TOFA) in rheumatoid arthritis (RA). Material and methods: Two hundred nine patients with active RA treated with TOFA, unresponsive to at least 2 conventional synthetic disease-modifying drugs, were recruited. Clinical characteristics were extracted from an electronic registry and supplemented with manual chart review and data linkage with ambulatory care. Drug retention and reasons for discontinuation were evaluated. Results: Median (interquartile range) follow-up in the whole sample was 16.9 (5.93-31.7) months. Mean (standard deviation) age was 51.44 (±11.84) years, with female predominance (n = 168, 80.4%). Only 30 patients (14.4%) had no pre-existing traditional cardiovascular (CV) risk factor at TOFA initiation. Tofacitinib retention rates were high, with median survival estimated at 89.3% at 6 months, 82.4% at 12 months, and 60.4% at 24 months. Ineffectiveness was the primary cause of discontinuation (n = 50). The rate of adverse events (AEs) was relatively low, with lipid abnormalities, blood count alterations, and infectious events among the most common. No major adverse CV event was reported. The incidence rate of AEs necessitating treatment switch was 60.34 (95% CI: 37-92) per 1,000 person-years of follow-up. Presence of multiple (> 3) CV risk factors was associated with lower odds of TOFA retention and treatment effectiveness. Conclusions: Tofacitinib demonstrated high retention rates and a favorable safety profile in RA patients, including those with traditional CV risk factors. Tofacitinib may be a valuable treatment option for RA patients when combined with individualized CV risk management. Further studies are warranted to explore the long-term effects of TOFA and its CV impact in larger populations.

IL-1ß, IL-10 and TNF-α polymorphisms may affect systemic lupus erythematosus risk and phenotype.

OBJECTIVES: Systemic lupus erythematosus (SLE) is an autoimmune disease, and IL-1ß, IL-10, and TNF-α genes are important in the pathogenesis of this disease. We studied the impact of IL-1ß-511, IL-1ß +3953, IL-10 -592, IL-10 -1082, TNF-α -308, TNF-α -238, and TNF-α +489 polymorphisms on SLE risk and phenotype in SLE patients and healthy controls. METHODS: We genotyped SLE patients and healthy controls by real-time PCR on QuantStudio 5 (Applied Biosystems) and measured levels of cytokines by enzyme-linked immunosorbent assay (ELISA). RESULTS: We indicated that TNF-α -308, IL-10 -592, IL-10 -1082, IL-1ß-511 and IL-1ß +3953 polymorphisms affect SLE risk. Furthermore, we exposed that some of the TNF-α +489, TNF-α -238, IL-10 -1082 and IL-1ß +3953 genotypes are connected with the SLE phenotype. Moreover, we discovered the linking between specific genotypes and the serum concentrations of TNF-α, IL-1ß, and IL-10. CONCLUSIONS: In conclusion, our study revealed that IL-1ß-511, IL-1ß +3953, IL-10 -592, IL-10 -1082, and TNF-α -308 polymorphisms may affect SLE risk and phenotype.

The Role of TNF-α and Anti-TNF-α Agents during Preconception, Pregnancy, and Breastfeeding.

Tumor necrosis factor-alpha (TNF-α) is a multifunctional Th1 cytokine and one of the most important inflammatory cytokines. In pregnancy, TNF-α influences hormone synthesis, placental architecture, and embryonic development. It was also shown that increased levels of TNF-α are associated with pregnancy loss and preeclampsia. Increased TNF-α levels in complicated pregnancy draw attention to trophoblast biology, especially migratory activity, syncytialisation, and endocrine function. Additionally, elevated TNF-α levels may affect the maternal-fetal relationship by altering the secretory profile of placental immunomodulatory factors, which in turn affects maternal immune cells. There is growing evidence that metabolic/pro-inflammatory cytokines can program early placental functions and growth in the first trimester of pregnancy. Furthermore, early pregnancy placenta has a direct impact on fetal development and maternal immune system diseases that release inflammatory (e.g., TNF-α) and immunomodulatory factors, such as chronic inflammatory rheumatic, gastroenterological, or dermatological diseases, and may result in an abnormal release of cytokines and chemokines in syncytiotrophoblasts. Pregnancy poses a challenge in the treatment of chronic disease in patients who plan to have children. The activity of the disease, the impact of pregnancy on the course of the disease, and the safety of pharmacotherapy, including anti-rheumatic agents, in pregnancy should be considered.

Is intra-articular infliximab therapy a good alternative to radionuclide synovectomy for a patient with refractory pigmented villonodular synovitis?

Pigmented villonodular synovitis (PVNS) is a rare disease that has clinical and histopathological characteristics of both benign proliferative disorder and a chronic inflammatory process of the synovial tissue. The primary mode of treatment is surgery followed by an adjuvant radiotherapy; however, the risk of recurrence is a significant (40-70%). Several publications suggest that the TNF-α inhibitors might be a treatment option. We present a case of a 29-year-old female diagnosed with PVNS of the knee joint, refractory to surgery and 3 radionuclide synovectomies. Because the possibilities of conventional therapy were exhausted, treatment with an intra-articular anti-TNF-α monoclonal antibody (infliximab) was performed. Despite a high safety profile and a good tolerance of that therapy we did not observe significant clinical and radiological improvement. To assess the effectiveness of intra-articular TNF-α inhibitors as an adjuvant treatment in PVNS, prospective studies are needed.

Microvascular damage - a marker of specific organ involvement in mixed connective tissue disease?

Mixed connective tissue disease (MCTD) is a complex entity, which incorporates features of systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), systemic sclerosis (SSc) and polymyositis/dermatomyositis (PM/DM). Nailfold videocapillaroscopy (NVC) is a simple, safe and non-invasive technique of capillary vessel assessment, allowing for qualitative and quantitative assessment of microcirculation. NVC plays a pivotal role in the diagnostic algorithm of connective tissue diseases, especially in systemic sclerosis (SSc). Numerous studies have shown a correlation between organ involvement and disease progression in SSc. In the current literature, there are limited data on relationship between NVC and organ involvement in MCTD patients. In the present article the relevant literature describing NVC examination in patients with MCTD and comparisons with some clinical situations are discussed.

Is the T-G-CT-G SNRNP70 haplotype another proof that mixed connective tissue disease is distinct from systemic lupus erythematosus and systemic sclerosis? A novel gene variant in SNRNP70 gene.

OBJECTIVES: U1-70K, encoded by the SNRNP70 gene, is a key early immunogen in connective tissue disease. The aim of the study was the genetic analysis of the SNRNP70 gene in mixed connective tissue disease (MCTD), systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) patients. METHODS: SNRNP70 genetic variants were detected using 3730 DNA Analyzer. SNRNP70 rs560811128 G/A (c.476-252 G/A), rs78616533delCT (c.475+130_475+131delCT) and rs117167710 T/C (c.393+326 T/C) variants were genotyped using the technique of sequence-specific hybridisation probe binding assays. SNRNP70 393_47 G/A mutation was detected using TaqMan SNP genotyping assay. RESULTS: We found one novel c.393+47G>A and three, c.476-252 G/A, c.475+130_475+131delCT and c.393+326 T/C, previously recorded variants. The present study revealed that T-G-CT-G haplotype demonstrated significantly higher frequencies in MCTD patients than in SLE and SSc patients. In MCTD patients c.475+130_475+131delCT distribution of genotype was gender-dependent and showed association with thrombo-/leukocytopenia. Mutation at position c.476-252G>A was predicted to possibly have an impact on splicing of the SNRNP70 transcript and it was present only in one MCTD patient. CONCLUSIONS: Our results demonstrated that the T-G-CT-G SNRNP70 haplotype is another proof that MCTD may be distinct from SLE and SSc. The novel c.476-252G>A mutation in SNRNP70 gene created a new acceptor splice site and may potentially alert of splicing of the SNRNP70 transcript.

Observational study of inflammatory arthritis treatment by etanercept originator switched to an etanercept biosimilar.

OBJECTIVES: The aim of the study was to assess the safety and efficacy of switching an etanercept originator to an etanercept biosimilar in rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, and ankylosing spondylitis patients. MATERIAL AND METHODS: In 162 patients etanercept originator treatment had been replaced with the biosimilar (Group 1), and in six patients the biosimilar was initiated as the first biological agent (Group 2). The efficacy and safety of the treatment were monitored at 3-6 months. RESULTS: In the majority of patients in Group 1 (n = 138) the etanercept biosimilar was well tolerated, whereas in 24 patients a switch back to the originator was required. The loss of efficacy was confirmed in nine patients using clinical scoring system, and nine patients reported subjective loss of efficacy; 13 patients reported adverse events, most often headache (n = 3) and skin lesions (n = 3). In four patients injection site reactions were present. The adverse events (AE) and/or the loss of the biosimilar efficacy were more commonly observed in women, patients with rheumatoid arthritis (especially in those who did not receive methotrexate), and in patients with a previous history of any other biological treatment. In patients in Group 2 the therapy was effective and no adverse events were observed. CONCLUSIONS: The etanercept biosimilar seems to be effective and well-tolerated in the majority of patients. Nevertheless, in some cases, switching from the originator to the biosimilar was associated with AEs or loss of efficacy.

IL-35, TNF-α, BAFF, and VEGF serum levels in patients with different rheumatic diseases.

OBJECTIVES: Inflammatory processes in rheumatic diseases spread via various types of immune system cells and tissues with the aid of inflammatory cytokines and growth factors and the participation of vascular endothelium. Research is still conducted to determine the role of individual factors in the pathophysiology of rheumatic diseases. The task is complicated because the multiplane network of cytokines is characterized by complex correlations manifesting as positive and negative feedback, which impedes the definitive interpretation of the role of specific cytokines. Therefore, it seems justified to perform a comparative analysis of the expression of at least several molecules in one study, which may help reveal their role in the pathogenesis of rheumatic diseases and have prognostic value. MATERIAL AND METHODS: The aim of the study involves the assessment and comparative analysis of the concentrations of interleukin 35 (IL-35), tumour necrosis factor α (TNF-α), B-cell-activating factor (BAFF), and vascular endothelial growth factor (VEGF) in peripheral blood serum in patients with rheumatoid arthritis (RA) (n = 43), systemic lupus erythematosus (SLE) (n = 28), antiphospholipid syndrome (APS) (n = 24), and mixed connective tissue disease (MCTD) (n = 9). The main intention is to search for biomarkers for specific rheumatic diseases. Cytokine and growth factor levels were determined using specific ELISA kits. RESULTS: Statistically significant differences in VEGF and IL-35 concentrations occurred between patients with APS vs. RA and SLE vs. RA. There was a significant high positive correlation between the concentration of BAFF and TNF-α (r = 0.77, p < 0.0000) in patients with APS, as well as in patients with SLE (r = 0.55, p = 0.00). CONCLUSIONS: BAFF and TNF-α may be promising biomarkers in patients with APS and VEGF in patients with RA. Additionally, IL-35 may be a useful marker for the diagnosis of APS. Positive correlation of BAFF and TNF-α concentrations in APS and SLE potentially indicates much more similar etiopathogenesis of these diseases than it could be previously predicted.

Antimalarials - are they effective and safe in rheumatic diseases?

Antimalarial drugs (AD) are a group of widespread therapeutic agents in multiple rheumatic indications. Although the effect of AD is mild and extended in time, low toxicity is their appreciated value. This paper describes the current state of knowledge on the mechanism of action, use, toxicity and pleiotropic effects of AD in the pharmacotherapy of autoimmune diseases.

Satisfaction and discontent of Polish patients with biological therapy of rheumatic diseases: results of a multi-center questionnaire study.

OBJECTIVES: Biologics are medications widely applied in the management of inflammatory rheumatic diseases. The drugs were found to be effective but their application is associated with some disadvantages. Medication with biologics is relatively expensive, and in Poland, it is carried out in specialized centers. The study was designed to evaluate various aspects of satisfaction and dissatisfaction of Polish patients treated with biologics. MATERIAL AND METHODS: An anonymous questionnaire was distributed in 23 Polish rheumatological centers involved in the treatment; 1212 returned questionnaires were used for analysis. Responses were received from 606 patients with rheumatoid arthritis, 427 with ankylosing spondylitis, 117 psoriatic arthritis, and 62 adult patients with juvenile idiopathic arthritis (in whom administration of the drugs had been introduced before they were 18 years old). The investigated group constituted about one-fifth of all rheumatic patients on biologics in Poland. RESULTS: A beneficial or very beneficial influence of the medication on the state of physical health was found mostly in patients with rheumatoid arthritis (51.3 and 30.5%) and ankylosing spondylitis (51.0 and 36.8%). Family life was improved by the treatment especially in patients with ankylosing spondylitis (40.7 and 35.6% beneficial and very beneficial, respectively), sleep quality and sexual life mostly in those with ankylosing spondylitis (beneficial/very beneficial influence 41.5/38.4, and 38.7/23.9, respectively). There was a rather small influence of biological treatment on the financial situation of the patients. In general, satisfaction with the treatment was evaluated as positive or very positive in 88% of all investigated patients.In a significant part of the patients, transportation to the medical center was considered as a disadvantage of the treatment. About one-third of the patients considered laboratory and imaging tests to be done before initiation of the medication as a difficulty, and for about 40% waiting time for qualification for the medication was a significant disadvantage. The route of drug administration was without importance for 4/5 of the patients. CONCLUSIONS: Summing up, the results were similar in the patients suffering from various diseases although those with psoriatic arthritis felt the highest satisfaction (possibly due to the positive aesthetic effect), and those with ankylosing spondylitis had significant improvement in sexual life (probably due to younger age). Relatively low satisfaction was found in patients with juvenile idiopathic arthritis. There was a small influence of medication on financial status of the patients. Application of biologics has few disadvantages and most of them are associated with the organization of health services (waiting time for the tests, transportation to the medical centers).

Discrepancies in assessment of patients with rheumatoid arthritis and secondary Sjögren's syndrome by DAS28-ESR and DAS28-CRP.

OBJECTIVES: To investigate whether a difference exists between DAS28 from CRP and DAS28 from ESR in patients with rheumatoid arthritis (RA) and secondary Sjögren's syndrome (sSS). MATERIAL AND METHODS: One group comprised patients with RA and sSS, the control group comprised patients with RA. The inclusion criteria for the RA and sSS group have been specified as follows: presence of at least one symptom of dryness, and also presence of anti-SS-A and anti-SS-B or at least focus score of one in biopsy. RESULTS: The disease activity score 28 (DAS28) was assessed using both ESR and CRP in 60 patients with RA and sSS and 59 patients with RA alone. However, concordance between these two methods was good (Cohen's κ coefficient κ = 0.60, 95% CI: 0.45-0.75 in the first group and κ = 0.71, 95% CI: 0.56-0.86 in the control group). In the group with RA and sSS, the mean value of DAS28-ESR = 5.2, whereas the mean value of DAS28-CRP = 4.7 (p < 0.0001). In the group with RA alone, mean DAS28-ESR = 4.7 while mean DAS28-CRP = 4.6; no significant difference was identified. Moreover, in RA patients with sSS, mean ESR = 39 mm/h compared with mean CRP at 25 mg/l. 79% of all patients demonstrated dysproteinaemia. There were connections between higher ESR and dysproteinaemia. In the control group there was no statistically significant difference between CRP and ESR. CONCLUSIONS: Both DAS28-ESR and DAS28-CRP are useful outcome measures in RA. However, in patients with RA and sSS, DAS28 should be evaluated based on CRP.

Capillaroscopy - a role in modern rheumatology.

Capillaroscopy is a non-invasive, easy and safe diagnostic technique designed to evaluate small vessels of the microcirculation in the nailfold. It can reveal both the general architecture of capillary rows and fine details of particular vessels. The most important indications for performing capillaroscopy include differential diagnosis of primary and secondary Raynaud's phenomenon, as well as assessment of scleroderma spectrum disorders. In systemic sclerosis capillary abnormalities appear and evolve in a clearly defined sequence called the scleroderma pattern, which correlates with internal organ involvement. Capillaroscopy is also listed as a systemic sclerosis classification criterion recognized by the European League Against Rheumatism (EULAR). With digitized equipment, capillaroscopy allows for precise qualitative and quantitative evaluation of the microcirculation and is a valuable tool in the rheumatologists' daily practice.

Immunity and early atherosclerosis in the course of systemic lupus erythematosus, mixed connective tissue disease and antiphospholipid syndrome.

Atherosclerosis is a chronic inflammatory disease of the arteries associated with various risk factors that promote lipid abnormalities, development and progression of atherosclerotic lesions, plaque rupture, and vascular thrombosis. Atherosclerosis is accelerated in autoimmune diseases. Non-invasive investigations showed increased intima-media thickness (IMT), carotid plaque, and coronary artery calcifications in patients with antiphospholipid syndrome, systemic lupus erythematosus and mixed connective tissue disease compared to controls. The balance between the proinflammatory and anti-inflammatory cytokines allows the immune equilibrium to be maintained. In autoimmune diseases the prevalence of proinflammatory factors leads to premature atherosclerosis. This review presents complementary knowledge on innate and adaptive immunity, cytokines and the role of inflammasomes in progression of early atherosclerosis.

Radionuclide synovectomy - essentials for rheumatologists.

Radionuclide synovectomy is a minimally invasive method of treating persistent joint inflammation. It involves intra-articular injection of radioactive colloids which induce necrosis and fibrosis of hypertrophic synovial membrane. The most common indication for radiosynovectomy is rheumatoid arthritis, although patients with seronegative spondyloarthropathies, unclassified arthritis, haemophilic arthropathy and other less common arthropathies can also benefit from this method. Radiosynovectomy is safe, well tolerated and efficacious. About 70-80% of patients respond well to the therapy. However, the therapeutic effects are considerably worse in patients with co-existent osteoarthritis and advanced joint degeneration. Despite its advantages, radionuclide synovectomy is not performed as often as it could be, so greater knowledge and understanding of this method are needed. The authors present the most important facts about radiosynovectomy that may help rheumatologists in their daily clinical practice.

Treatment of rheumatic diseases and hepatitis B virus coinfection.

We often encounter rheumatological patients coinfected with hepatitis B in daily practice. In this paper, we will discuss the basic characteristics of the virus of hepatitis B, course of infection, the safety of rituximab, tocilizumab, abatacept treatment and therapeutic recommendations in management of patients with rheumatic diseases.
