A multitude of studies are establishing the mitochondrial dysfunction and it's pathophysiological sequelae as key events, contributing to the progression of rheumatoid arthritis. The oxidative stress and release of mitochondrial molecules into the intra- and extracelular compartments are a result of the loss of function and integrity of the mitochondria. Some biomarkers, which accurately reflect the state of oxidative stress in rheumatoid arthritis patients, have been successfuly identified. The change in the levels of those markers as a result of treatment with biologic DMARDs (bDMARDs) has been analyzed. However, there is still insufficient data regarding the effect of the target-synthetic DMARDs (tsDMARDs) on the oxidative stress.","PeriodicalId":380764,"journal":{"name":"Rheumatology (Bulgaria)","volume":"482 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134114767","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}

Case presentation: A healthy 54 years old male with no previous history of any medical condition was presented with bilateral hand and bilateral knee pain after one week of receiving his first dose of Pfizer-BioNTech Covid-19 vaccine. Clinical examination revealed swelling, tenderness, and erythema over the right index metacarpophalangeal joint and the medial aspect of the right knee. Radiographs of the hand and knee were normal. Laboratory investigations were within normal values except for an elevated ESR (15 mm/hr.) and a positive CRP titer of 48 mg/l. The symptoms entirely resolved after two weeks of non-steroidal anti-inflammatory medications. Conclusions: Although rare, however, ReA could be presented as a complication of Covid-19 vaccination, and physicians should be aware of the possibility of its occurrence.","PeriodicalId":380764,"journal":{"name":"Rheumatology (Bulgaria)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114653513","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}

The aim of this review is to analyze the information available up to date on the course of COVID-19 in patients with autoimmune rheumatic diseases (ARD), the frequency of complications in these patients, the effectiveness and side effects of vaccination against COVID-19. Various studies in Europe and the United States have found that the risk of severe COVID-19 in patients with ARD is similar to that in the general population. Negative prognostic factors are thought to be old age, comorbidity, moderate / high ARD activity, and corticosteroid (CS) intake at doses> 10 mg / day. Patients with systemic ARD are considered to be at higher risk of thromboembolic events due to chronic inflammation and / or the presence of antiphospholipid syndrome, as well as the nature of COVID-19 - an endothelial lesion causing thrombosis and microangiopathy. It is observed a higher risk of severe pneumonia in patients treated with Rituximab, as well as an increase in hospitalizations and deaths amongst them. The opposite trend is observed in patients treated with anti-TNF. With the development of vaccines against COVID-19, questions arise about their effectiveness in patients with ARD, as well as the frequency of complications associated with them. In these studies, slightly lower levels of neutralizing antibodies were observed in patients with ARD compared to the general population, most commonly associated with Methotrexate or targeted synthetic DMARDs. The most common side effects seen in these patients after vaccination are pain at the injection site, fatigue and headache. Complaints of the musculoskeletal system are more common in patients with ARD than in the general population. Exacerbations of the underlying disease following vaccination, requiring hospitalization, are rare.","PeriodicalId":380764,"journal":{"name":"Rheumatology (Bulgaria)","volume":"25 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130970597","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}

Sarcopenia is characterized by progressive and generalized loss of skeletal muscle mass and strength with a risk of adverse outcomes such as physical disability and poor quality of life. The study aimed to assess the prevalence of sarcopenia in patients with ankylosing spondylitis. A case-control study was conducted at Rheumatology Unit from January 2019 to July 2019. The study population consisted of 50 Iraqi patients diagnosed with AS and 50 healthy control. Demographic data, physical activity using General Practice Physical Activity Questionnaire (GPPAQ), disease activity scores using Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were recorded. Sarcopenia assessment was done by using a dual-energy x-ray absorptiometry scan for body composition analysis and measuring skeletal mass index (SMI). The maximal voluntary grip strength of the hand was measured with an electronic dynamometer. Physical function was assessed by a 4-meter usual gait speed test. The prevalence of presarcopenia was 6% in both studied groups, while sarcopenia was 10% in AS patients. The mean value of BMI is significantly lower in patients with sarcopenia than in those without (p=0.001). The vast majority of the sarcopenic group (80%) were physically inactive which was statistically significant compared with the non-sarcopenic group (p=0.033). No significant association of treatment with anti-TNF or its duration was found between sarcopenia and non-sarcopenia groups (p=0.377; p=0.187). Both LM and handgrip showed fair validity to differentiate between AS patients and controls. Patients with AS are at higher risk of developing early sarcopenia than in healthy controls. Lower BMI and longer disease duration increase the risk of sarcopenia, while differences in gender, smoking and the use of anti-TNF do not influence the risk. Physical activity may improve muscle strength and perhaps decrease the risk.","PeriodicalId":380764,"journal":{"name":"Rheumatology (Bulgaria)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132729742","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}

Methods: According to the International Criteria for Behcet's Disease (ICBD), fifty adult Behçet's disease patients were enrolled in the study, and forty healthy adult subjects were included in a case-control study. An enzyme-linked immunosorbent assay was used to obtain quantitative data. Results: The suPAR level was not statistically different between the patients with BD patients and the controls. No correlation was found between suPAR levels and disease activity (BDFAC). Conclusion: Very few studies analyzed the clinical value of suPAR level in patients with BD and its correlation with disease activity. Our results show that suPAR does not seem to play a role in the disease mechanism of BD.","PeriodicalId":380764,"journal":{"name":"Rheumatology (Bulgaria)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127499746","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}
