Currently, RA is considered as a syndrome characterized by clinical and pathogenetic heterogeneity associated with a variety of mechanisms of pathological activation of innate and acquired immunity, determining the variability of the course and outcome of the inflammatory process and effectiveness of therapy. Based on the detection or absence of rheumatoid factor (RF) IgM and antibodies to cyclic citrullinated peptides (ACCP), RA can be conventionally divided into two subtypes (phenotypes): seropositive RA and seronegative RA, but thanks to improvement of laboratory diagnostic methods the spectrum of autoantibodies detected in RA has increased significantly. Diagnosis of seronegative RA based on classification (rather than diagnostic) criteria can be difficult, especially in the early stages of the disease, and the diagnosis is made only during long-term follow-up of patients. It complicates the timely prescription of adequate anti-inflammatory therapy. This article summarizes the data on genetic predisposition, immunopathogenesis, biomarkers, clinical spectrum, instrumental diagnosis and pharmacotherapy of seronegative RA.","PeriodicalId":21518,"journal":{"name":"Rheumatology Science and Practice","volume":"201 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73757585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Switching to another biologic with the same mode of action provides greater opportunity for long-term management of patients with rheumatoid arthritis (RA). In clinical practice, especially in the context of the COVID-19 pandemic, such switching occurred for non-medical reasons as well. However, there is no information about switching from interleukin 6 (IL-6) receptor (R) inhibitor to direct IL-6 inhibitor. Objective – to assess the efficacy and safety of therapy in RA patients, after switching from IL-6R inhibitors (tocilizumab (TOC), sarilumab (SAR)) to olokizumab (OKZ) for reasons not related to the loss of their efficacy or adverse events. Material and methods. In this retrospective cohort study efficacy parameters and routine biochemical data were analyzed using descriptive statistics – mean values with standard deviation for continuous parameters and absolute and relative frequency for binary variables. Adverse events (AE) were reported according to patient’s files. The statistical significance and changes of the analyzed variables by visits were determined using paired t-test. Fisher’s exact test or chi-square test was used to compare the proportion of patients with improvement/no change and of patients with worsening. All tests were 2-sided, and p<0.050 was considered statistically significant. As this was an observational study, the statistical criteria have not been pre-specified. Results. We analyzed results obtained during 5 visits (2 visits before switching, switching visit and 2 visits after switching) in 110 RA patients who switched to OKZ 64 mg every 4 weeks subcutaneously (SC). Most patients (79.1%) were women, and 70% of patients were both positive by rheumatoid factor and antibodies to cyclic citrullinated peptide. Mean RA duration was 11 [6; 16] years, previous treatment duration was 44 [27; 62] months and mean interval before switching to OKZ was 35 [31; 68] days. This relatively long interval led to an increase in DAS28-ESR (Disease Activity Score 28 with determination of erythrocyte sedimentation rate) from 2.4 [1.9; 3.0] to 2.6 [2.1; 3.5] and DAS28-CRP (DAS28 with determination of C-reactive protein level) from 2.8 [2.0; 3.3] to 2.9 [2.2; 4.0] (the trends were similar in patients who received combined therapy and monotherapy). After switching, all of RA symptoms and indexes have been improved compared with the switching visit (some of them were significantly better even compared with stable therapy period e. g. DAS28-CRP was 2.4 [2.0; 3.1] in the overall group and 2.4 [2.1; 2.7] in the monotherapy group). AEs were registered in only 7 (6.4%) patients, of which 1 (0.9%) case (an exacerbation of herpes infection) was considered as serious.

The development of this pathology is a complex process that occurs under the influence of systemic autoimmune inflammation and associated with heart damage (pericarditis, myocarditis, endocarditis, сcoronary artery disease, myocardial infarction), disorders of the cardiac conduction system (various arrhythmias), atherosclerosis, arterial hypertension, pulmonary hypertension, thrombosis against connected with bleeding disorders (especially associated with antiphospholipid syndrome), traditional risk factors, as well as the negative effect of anti-rheumatic therapy. Mostly HF in SLE occurs in a subclinical form with a preserved ejection fraction, and is detected using instrumental methods in more than 60% of patients. The management of patients with SLE and HF requires early diagnosis of this pathology, to do this, various diagnostic methods are used (particularly, echocardiography with speckle tracking imaging technique) and the identification of biomarkers such as NT-proBNP.

Patients and methods. A single-stage study of patients with IIRD who were on inpatient treatment or who applied to the consultative and diagnostic center of the V.A. Nasonova Research Institute of Rheumatology was conducted, who received both components of the Sputnik V vaccine. The control group included immunized persons without IIRD. All participants were interviewed by a research doctor with filling out a unified questionnaire, additional information was obtained from medical documentation. Results. The study included 325 patients with IIRD and 138 healthy controls. After vaccination with the first component, the number of patients with IIRD, in whom the development of local and systemic adverse events (AEs) was noted, was significantly lower compared to the control (20.3% and 38.4% respectively; p<0.001). These differences also persisted after immunization with the second component (12.3% and 28.3% respectively, p<0.001). After complete vaccination, no AEs were documented in 40.3% of patients and 22.5% of the control group (p<0.001). Female sex and, possibly, methotrexate therapy increases the risk of developing local and systemic AEs on the first component of the vaccine, rituximab therapy - on the second.

Material and methods. The study included 50 women with RA and 46 with SLE aged 18 to 65 years without a history of diabetes and fasting hyperglycemia. The concentration of leptin (ELISA), insulin (electrochemiluminescence analysis) was determined in all patients, and the HOMA-IR index was calculated. Hyperleptinemia was diagnosed at leptin concentrations >11,1 ng/ml, insulin resistance (IR) – at HOMA-IR values ≥2,77. Three main phenotypes of overweight were distinguished: “classic” (BMI≥25 kg/m2  + hyperleptinemia), “healthy” (BMI≥25 kg/m2 , without hyperleptinemia), “hidden” or “latent” (BMI<25 kg/m2  + hyperleptinemia), as well as “normal weight” (BMI<25 kg/m2 , without hyperleptinemia). Results. Patients with RA and SLE were similar in age (p=0.4), disease duration (p=0.2) and BMI (p=0.5). Hyperleptinemia was found in 46% of women with RA and 74% – with SLE (p=0.005), IR – in 10% and 22% of patients, respectively (p=0.2). The “classic” phenotype of overweight was diagnosed in 30%, “healthy” – in 8%, “hidden” – in 16% of cases with RA and in 44%, 0% and 30% of cases with SLE, respectively. IR was found in 3%, hypertension – in 6% of patients with “normal weight”. With the “classical” phenotype, IR (29%) and hypertension (66%) were more common than with “normal weight” (p<0.01 in all cases), with the “hidden” phenotype, significant differences were obtained only in hypertension frequency (45%; p=0.0012), but not IR (18%). 3 out of 4 women with a history of cardiovascular complications suffered from “classic” overweight, one patient had a “normal weight”. Conclusion. In women with SLE up to 65 years of age, the frequency of hyperleptinemia, but not IR, is higher than in patients with RA. In both diseases, the “classic” overweight phenotype is most common. In RA, a “hidden” phenotype was detected less often than in SLE, at the same time, a “healthy” phenotype is not characteristic of SLE. The frequencies of metabolic disorders and hypertension is low with the “normal weight” and “healthy” phenotype, high – with the “classic”, intermediate – with the “hidden” phenotype.","PeriodicalId":21518,"journal":{"name":"Rheumatology Science and Practice","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88720990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective – to study the efficacy, immunogenicity and safety of the 23-valent polysaccharide pneumococcal vaccine (PPV-23) in patients with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (AРS). Materials and methods. 91 patients were included in the study: 78 with SLE, of which 18 (23 %) – with secondary AРS, 13 – with primary AРS. 85 patients received immunosuppressive therapy, including 30 – genetically engineered biological drugs (bDMARD); 23 – anticoagulants. PPV-23 was administered subcutaneously, patients were observed for a year after vaccination. Results. Local reactions were observed in 49% of patients with SLE and secondary AРS, in 23% of patients with primary AРS. General reactions were noted in isolated cases, were short-term and did not require additional prescriptions. During the follow-up period, no exacerbations of SLE, relapses of thrombosis and thromboembolism associated with vaccination were detected; no development of new autoimmune diseases was registered. 10 (13%) patients with SLE were immunized against the background of high activity of the disease, no adverse reactions were recorded. In some patients, a transient increase in a-DNA and ANF was observed during the year without signs of exacerbation of the disease. 56% of patients with SLE and secondary AРS, 15.4% with primary AРS were “responders” to the vaccine. There was no negative effect on the immune response of the dose of GC >10 mg/day, age, duration and activity of the disease. With the treatment of bDMARD, a full-fledged vaccine response was recorded much less frequently than with standard therapy (38% and 67.4%, respectively; p=0.01). After vaccination, there was a significant decrease in the number of lower respiratory tract infections (LRTI) (p=0.0001), including community-acquired pneumonia (PN) (p=0.03) and acute bronchitis (p=0.04), ENT infections (p=0.001). In the treatment of rituximab (RTM), compared with belimumab (BLM), a greater number of LRTI was observed, mainly due to PN. After vaccination on RTM therapy, the number of INDP in general (p=0.008) and PN in particular (p=0.03) decreased, isolated cases of LRTI and ENT organs were recorded on BLM therapy. Within 4–6 years after vaccination, 30 patients with SLE retained the clinical effect of vaccination, while immunogenicity decreased to 18%. Conclusion. Safety, sufficient immunogenicity, and clinical efficacy of PPV-23 in patients with SLE and AРS have been shown. The use of bDMARD reduces the vaccine response. Immunization performed prior to or during treatment with bDMARD lasting <1 year increases the number of vaccine responders.","PeriodicalId":21518,"journal":{"name":"Rheumatology Science and Practice","volume":"25 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89564180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
