Uncontrolled hypercoagulation and inflammation (thromboinflammation), which are both independent and closely related and amplifying each other pathological processes, form the basis for pathogenesis of a wide range of diseases and complications, including immuno-inflammatory (autoimmune) rheumatic diseases, with the development of potentially fatal injuries of internal organs. Thrombotic microangiopathy is one of the most prominent prototypes of thromboinflammatory pathological conditions. The close link between environmental factors, hemostasis genetic defects and the complement system, inflammation and autoimmunity as pathogenetic mechanisms of microthrombosis draws particular attention to studying thrombotic microangiopathy in immuno-inflammatory rheumatic diseases, primarily systemic lupus erythematosus, antiphospholipid syndrome and scleroderma renal crisis. In future, these studies may be important for expanding the idea of the role of autoimmune mechanisms in pathogenesis of critical hemostasis disorders in human diseases, and for developing new approaches to therapy. Recently, special attention has been paid to the treatment of systemic lupus erythematosus and antiphospholipid syndrome with eculizumab, which is humanized monoclonal IgG2/4k antibody that blocks the complement component C5a and the membrane attack complex (C5b-9) formation, and which is registered for the treatment of atypical hemolytic uremic syndrome, paroxysmal nocturnal hemoglobinuria, as well as severe forms of myasthenia gravis and neuromyelitis optica. Further studies in this direction will create prerequisites for improving the prognosis not only in patients with orphan disorders, but also for widespread human diseases.

Background:Infectious diseases are increased in patients with rheumatic disorders; vaccination improves morbidity and mortalityObjectives:The aim of this study was to describe the frequency of vaccination in patients with rheumatic disorders and to compare the results with those obtained in 2009 and 2013 in a similar population. We also identified factors leading to lack of vaccination and patients beliefs on vaccines.Methods:Multicentric cross sectional study in patients with autoinmune diseases from external rheumatology offices. Evaluation of vaccination status and patients´ knowledge about vaccines were studied. A comparative analysis was carried out with the series registered in 2009 and 2013 in a similar population.Results:179 patients (158 female, 88.3% and 21 male, 11.7%) were evaluated. Median age was 52 years. Main pathologies were: Rheumatoid Arthritis 65.9% (n:118), Systemic Lupus Erythematosus 11.7% (n:21), Systemic Sclerosis 3.9% (7), Sjogren Syndrome n = 3.4% (n:6), other diseases 15% (n: 27). Median disease duration: 8.87 years. Ninety three percent of patients (n:167) were taking inmunomodulators and 36.8% (n: 66) were using oral corticosteroids (20mg/day or less); 26,8% patients (n: 48) were receiving biological therapies. Vaccination frequency in the population was: Influenza 82% (147); 13-valent conjugate pneumococcal 69.3% (124), 23-valent pneumococcal 64.2% (115) and hepatitis B 62% (111). Comparative with 2009 and 2013 series there was an increase in the rate of vaccinated patients: influenza (82% vs. 39,1% and 74,2% respectively), antineumococcal (64% vs. 17% and 29%) and hepatitis B (62% vs. 6,7% and 26,7%).Reasons for non-vaccination were absence of medical indication (41% of patients for hepatitis B; 32% for 23-valent pneumococcal; 38% for 13-valent pneumococcal and 34% for influenza).139 patients (77, 7%) knew the benefits of vaccines, 164 (91, 6%) thought vaccines are useful; 134 (74,9%) reported that vaccines may decrease dying probability, 155 (86,5%) thought that vaccines are effective to prevent diseases and 149 patients (83,2%) believed that they prevent serious infections. 71 patients (39%) believed that vaccines can lead to serious consequences and 99 (55,3%) that they are more likely to acquire infections than the rest of the population.Conclusion:Frequency of vaccination has increased since 2009 but there is still misinformation regarding vaccines risks and benefits. Promotion and information is essential to improve adherence.References:[1]2019 update of EULAR recommendations for vaccination in adult patients with autoimmune inflammatory rheumatic diseases.

Objective Osteonecrosis (ON), also known as avascular necrosis, is characterized by the collapse of the architectural bone structure secondary to the death of the bone marrow and trabecular bone. Osteonecrosis may accompany many conditions, especially rheumatic diseases. Among rheumatic diseases, osteonecrosis is most commonly associated with systemic lupus erythematosus (SLE). We assessed prevalence and distribution pattern of symptomatic ON in patients with SLE and compare the natural courses of hip and knee ON. Methods 912 SLE patients admitted between 1981 and 2012 were reviewed. SLE patients with symptomatic ON were retrospectively identified both from the existing SLE/APS database. The prevalence of symptomatic ON was calculated; with ON, the joint involvement pattern was determined by examining the distribution of the joints involved, and then the data about the hip and knee joints were entered in the Kaplan-Meier analysis. Kaplan-Meier methods were used to calculate 5- and 10-year rates of ON-related hip (the hip group) and knee survival (the knee group). Results Symptomatic ON developed in various joints in 97 of 912 patients with SLE, and the overall prevalence of ON was detected as 10.6%. The mean age at the time of SLE and ON diagnoses were 27.9 ± 9.9 (14–53) and 34.2 ± 11.3 (16–62) years, respectively. The mean duration from diagnosis of SLE to the first development of ON was 70.7± 60.2 (range = 0–216) months. The most common site for symptomatic ON was the hips (68%, n=66), followed by the knees (38%, n = 37). According to Kaplan-Meier analysis, hip and knee joint survival rates associated with 5-year ON were 51% and 88%, and 10-year survival rates were 43% and 84%, respectively. Conclusion We observed that the prevalence of symptomatic ON in patients with SLE was 10.6%. With the estimated 10-year survival rates of 40% versus 84% for the hip and knee joints, respectively, hip involvement may demonstrate a more aggressive course to end-stage osteoarthritis than the knee involvement.

ObjectivesPatients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) have increased risk of cardiovascular disease (CVD). We investigated whether single nucleotide polymorphisms (SNPs) at autoimmunity risk loci were associated with CVD in SLE and RA.MethodsPatients with SLE (n=1045) were genotyped using the 200K Immunochip SNP array (Illumina). The allele frequency was compared between patients with and without different manifestations of CVD. Results were replicated in a second SLE cohort (n=1043) and in an RA cohort (n=824). We analysed publicly available genetic data from general population, performed electrophoretic mobility shift assays and measured cytokine levels and occurrence of antiphospholipid antibodies (aPLs).ResultsWe identified two new putative risk loci associated with increased risk for CVD in two SLE populations, which remained after adjustment for traditional CVD risk factors. An IL19 risk allele, rs17581834(T) was associated with stroke/myocardial infarction (MI) in SLE (OR 2.3 (1.5 to 3.4), P=8.5×10−5) and RA (OR 2.8 (1.4 to 5.6), P=3.8×10−3), meta-analysis (OR 2.5 (2.0 to 2.9), P=3.5×10−7), but not in population controls. The IL19 risk allele affected protein binding, and SLE patients with the risk allele had increased levels of plasma-IL10 (P=0.004) and aPL (P=0.01). An SRP54-AS1 risk allele, rs799454(G) was associated with stroke/transient ischaemic attack in SLE (OR 1.7 (1.3 to 2.2), P=2.5×10−5) but not in RA. The SRP54-AS1 risk allele is an expression quantitative trait locus for four genes.ConclusionsThe IL19 risk allele was associated with stroke/MI in SLE and RA, but not in the general population, indicating that shared immune pathways may be involved in the CVD pathogenesis in inflammatory rheumatic diseases.

Since we have gained an understanding of the immunological pathophysiology of rheumatic diseases such as rheumatoid arthritis and systemic lupus erythematosus, treatment based on biological drugs has become a fundamental axis. These therapies are oriented towards the regulation of cytokines such as tumour necrosis factor-alpha (TNF-α), interleukin (IL)-6, IL-1, and the modulation of cell-mediated immunity (B cells and T cells) by anti CD20 or anti CTAL-4 agents, and can increase the risk of associated infections or adverse events (AE). In this context, the entry of biotherapeutics represented a challenge for pharmacovigilance, risk management and approval by the main global regulatory agencies regarding biosimilars, where efficacy and safety are based on comparability exercises without being an exact copy in terms of molecular structure. The objective of this review is divided into three fundamental aspects: (i) to illustrate the evolution and focus of pharmacovigilance at the biopharmaceutical level, (ii) to describe the different approved recommendations of biopharmaceuticals (biological and biosimilars) and their use in rheumatic diseases (RDs) such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE) and other less frequent RD like cryopyrin-associated autoinflammatory syndromes (CAPS), and (iii) to identify the main AE reported in the post-marketing phase of RD biopharmaceuticals.

Introdução: as doenças reumáticas apresentam manifestações musculoesqueléticas e sistêmicas que podem acometer quaisquer regiões do corpo. No caso das mãos, uma das manifestações é a diminuição da força de preensão palmar destes indivíduos. Objetivo: verificar os efeitos da cinesioterapia sobre a força de preensão palmar em indivíduos com doenças reumáticas. Material e métodos: estudo longitudinal e intervencionista com 24 indivíduos portadores de doenças reumáticas (osteoartrite, artrite reumatoide, fibromialgia, lúpus eritematoso sistêmico, esclerose sistêmica e dermatopolimiosite), com idade média de 50,23 anos. Os indivíduos realizaram 10 sessões de fisioterapia, baseadas em cinesioterapia, com exercícios globais e funcionais, 02 vezes por semana, com duração média de 50 minutos, de março de 2014 a novembro de 2015, na Clínica de Fisioterapia da Universidade de Passo Fundo, Passo Fundo/RS. As avaliações inicial e final envolveram a coleta de dados e a mensuração da força de preensão palmar, por meio da dinamometria manual. Resultados: observou-se que os indivíduos apresentaram melhora da força de preensão palmar, porém os resultados foram estatisticamente significativos apenas para a mão direita dos indivíduos com osteoartrite, para ambas as mãos dos indivíduos com artrite reumatoide e lúpus eritematoso sistêmico e para a força de preensão palmar geral dos indivíduos. Conclusão: o protocolo fisioterapêutico proposto produziu aumento da força de preensão palmar de indivíduos com doenças reumáticas.Palavras-chave: Força da mão. Doenças reumáticas. Fisioterapia.

In the case of the hands, one of the manifestations is the decrease of the handgrip strength of these individuals. Aim: to verify the effects of kinesiotherapy on handgrip strength in individuals with rheumatic diseases. Material and methods: longitudinal and interventional study with 24 individuals with rheumatic diseases (osteoarthritis, rheumatoid arthritis, fibromyalgia, systemic lupus erythematosus, systemic sclerosis and dermatopolymyositis), mean age 50.23 years. The individuals performed 10 sessions of physiotherapy, based on kinesiotherapy, with global and functional exercises, 02 times a week, with an mean duration of 50 minutes, from March 2014 to November 2015, at the Physiotherapy Clinic of Passo Fundo University, Passo Fundo/RS. The initial and final evaluations involved data collection and measurement of handgrip strength using manual dynamometry. Results: it was observed that the individuals presented improvement of the handgrip strength, but the results were statistically significant only for the right hand of individuals with osteoarthritis, for both hands of individuals with rheumatoid arthritis and systemic lupus erythematosus and for the handgrip strength of individuals. Conclusion: the proposed physiotherapeutic protocol produced an increase in the handgrip strength of individuals with rheumatic diseases.Keywords: Hand strength. Rheumatic diseases.
