Ann Med Surg (Lond) 2020; 60:579-582. [PMID: 33304568 PMCID: PMC7708690 DOI: 10.1016/j.amsu.2020.11.043] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 11/12/2020] [Accepted: 11/12/2020] [Indexed: 11/24/2022] Open
Abstract
Background Rheumatoid arthritis (RA) is the most common autoimmune inflammatory arthritis in adults. Prevalence estimates of rheumatoid arthritis vary in the world. Occupational factors and geographical location might contribute to a higher risk of developing the disease, however the exact etiology remains unknown. The aim of our study was to estimate the prevalence of RA among hospital workers in the North of Jordan and to compare this prevalence with that in the general population. In addition to describing the characteristics of RA patients. Methods The study was performed in two stages; during the first stage a specially designed questionnaire was conducted by trained residents with 2569 hospital workers from 6 government hospitals to identify individuals with RA. Suspected individuals of having RA identified in stage one were invited and examined further by two rheumatologists for confirmation of the diagnosis. Results A total of 2569 employees were interviewed; among them 1240 (48.5%) were males and 1318 (51.5%) were females. The mean (SD) age was 34±(8.4) years. In the second stage the diagnosis of RA according to ACR criteria 1987 was confirmed in 8 individuals (2 males and 6 females). Male: Female (M: F) ratio was 1:3 with mean (SD) age 43.38 (7.52) years. The estimated prevalence of RA among hospital workers in the North of Jordan was 8/2569 = 0.00311, 31.1:10.000, 0.31%, (95% confidence interval, 9.6–52.7:10.000). Conclusion The prevalence of RA among hospital workers in the North of Jordan is 0.31%, similar to that of other parts of Jordan and neighboring regions. Rheumatoid arthritis is a chronic disabling disease. Data regarding RA in Jordan is very limited. We conducted this study to shed light on how widespread RA. Our study showed similar prevalence of RA in surrounding regions, suggesting influence of environmental and occupational factors. We hope this may help advance patient care and management.

Abstract
Objectives This study aims to estimate the prevalence of rheumatoid arthritis (RA) and spondyloarthritis (SpA) in Turkey using the same telephone questionnaire developed for screening RA and SpA in France and used in Serbia and Lithuania. Material and methods The study was performed in two steps. In step I, the French questionnaire was translated into Turkish and validated through a group of 200 patients (80 males, 120 females; mean age 44.0±13.1 years; range 19 to 75 years) followed up at the rheumatology departments of University Hospitals in Antalya and Ankara. In step II, the validated Turkish questionnaire was administered face-to-face to randomly selected 4,012 subjects (1,670 males, 2,342 females; mean age 41.5±16.8 years; range 16 to 97 years) by trained general practitioners across the country, in 25 prov- inces for case detection. The subjects who were suspected of having RA or SpA in accordance with the questionnaire were invited to the nearest university hospital for rheumatologic examination in order to confirm the diagnosis. Results In step II, a total of 25 subjects (2 males, 23 females) were diagnosed as RA. The standardized RA prevalence for the general population of Turkey was calculated as 0.56% (95% confidence interval [CI]; 0.33-0.79), 0.10% (95% CI; -0.05-0.25) for males and 0.89% (95% CI; 0.51-1.27) for females. A total of 18 subjects (3 males, 15 females) were diagnosed as SpA. The standardized SpA prevalence for the general population of Turkey was 0.46% (95% CI; 0.25-0.67), 0.17% (95% CI; -0.03-0.37) for males and 0.65% (95% CI; 0.32-0.98) for females. The prevalence of RA was highest in the Northern region (2.00%) and the prevalence of SpA was highest in the Central region (1.49%). Conclusion The prevalences of RA and SpA in Turkey are close to each other and there are significant inter-regional variations in prevalences of both RA and SpA.

Abstract
We described the recent spatial distribution of rheumatoid arthritis in Turkey and assessed the role of environmental variables in this distribution. We developed an observed rheumatoid arthritis (RA) incidence grid map by using georeferenced rheumatoid arthritis case data (2011) from the centres of 81 provinces and the kriging method with a spherical variogram model in geographic information systems (GIS). We also modelled rheumatoid arthritis incidence in GIS by using complementary spatial database including the grid map layers of 14 environmental variables of Turkey. We conducted principle component analysis and multiple regression to investigate the relationships among variables and develop a model, respectively. The produced model was run in GIS to obtain a predicted (model) RA map. We tested the reliability of the model map by residual statistics and found the model map dependable. Observed and model incidence maps revealed the geographic distribution of rheumatoid arthritis cases in Turkey. The mean temperature, minimum temperature, maximum temperature, water vapour pressure, elevation, potential evapotranspiration, latitude, distance to seas, sunshine fraction, precipitation, longitude and aspect variables were found to have significant impacts on rheumatoid arthritis. Consequently, the model incidence map established a good background to predict rheumatoid arthritis cases following environmental changes.

Abstract
We sought to determine the frequency of I/D polymorphism genotypes of angiotensin converting enzyme gene in Turkish patients with rheumatoid arthritis. Genomic DNA obtained from 256 individuals (110 patients with rheumatoid arthritis and 146 healthy controls) was used in the study. ACE gene I/D polymorphism genotypes were determined using polymerase chain reaction using I and D allele-specific primers. There was a statistically significant difference between the groups with respect to genotype distribution (p=0.001). A significant difference was found in frequencies of ACE I/D alleles between patients and controls, with RA patients having a higher representation of D and lower representation of I alleles compared to controls (p<0.001). As a result of our study, angiotensin converting enzyme gene I/D polymorphism DD genotype could be a genetic marker in rheumatoid arthritis in the Turkish study population.

Abstract
Rheumatoid arthritis (RA) is a chronic, systemic and an autoimmune disease characterized by inflammation of the synovial membrane that affects approximately 1 % of the total world population. Rheumatoid factor (RF) is a widely used auto antibody in diagnosis of the RA and found positive in 50-80 % of the patients but with a lower specificity. On the other hand, anti-cyclic citrullinated peptide (anti-CCP) is the latest serological marker with a specificity around 98 %. This field survey was conducted in different regions to investigate the frequency of RF and anti-CCP and also frequency of RA in a northern province of Turkey. This study was conducted in 70 local areas (12 urban and 58 rural) in the province of Tokat, which is located in northern Turkey. The population of Tokat was reported to be 828,000 at the last census and about 530,000 individuals aged > 18 years old. The study population of 941 subjects (462 male and 479 female; urban 501 and rural 440) was selected by random sampling method among 530,000 individuals. Of the 941 healthy controls assigned to the study, 479 of them were female (51 %) and 462 of them were males (49 %), and median age of all participants was 41 ± 17. Twenty-six subjects were RF positive (2.8 %), and 9 patients were anti-CCP positive (1 %). The presence of both RF and anti-CCP antibodies has also been shown in two patients (0.2 %). In conclusion, we demonstrated that the frequency of RA was 0.53 %, RF presence was 2.8 %, and anti-CCP presence was 1 % in total 941 healthy subjects enrolled into study.

Abstract
OBJECTIVE To investigate the prevalence of eight common rheumatic diseases in a large Chinese population. METHODS A population-based epidemiological investigation of the prevalence of eight common rheumatic diseases in a suburb of Beijing was conducted in 14 642 individuals. A community-based survey was carried out using a screening questionnaire. Positive responders were included in a clinical and laboratory examination. Diagnosis was based on the criteria of ACR or those used widely in literature. RESULTS A total of 10 556 inhabitants were interviewed. Forty-three cases of RA were identified with an age-adjusted prevalence of 0.28% (95% CI 0.19%, 0.41%). Gout was diagnosed with a crude prevalence of 0.09% (95% CI 0.05%, 0.17%). Psoriasis was reported in 28 individuals with a prevalence of 0.27% (95% CI 0.18%, 0.38%). This included two cases diagnosed with PsA, resulting in a prevalence of 7.14% (95% CI 0.88%, 23.5%) in psoriasis patients and 0.02% (95% CI 0%, 0.07%) in the general population. Three individuals were identified with SLE, with a prevalence of 0.03% (95% CI 0%, 0.06%). One individual was identified with SSc and the calculated prevalence was 0.01% (95% CI 0%, 0.05%). One case of Behçet's disease was identified, giving a prevalence of 0.01% (95% CI 0%, 0.05%). CONCLUSION This large-scale epidemiological survey provides an estimate of the burden of rheumatic diseases in China.

Abstract
The aim of the present study was to estimate the prevalence of rheumatoid arthritis in the southern part of Denmark. Using a screening questionnaire, telephone interview, register data, and a clinical examination cases were ascertained from a random sample of 4995 individuals over the age of 15. As case definition we used the original and modified 1987 American College of Rheumatology classification criteria. The overall point prevalence was 0.26% (95% confidence interval: 0.13-0.39) in the total sample and 0.35% (95% confidence interval: 0.17-0.52) among the responders; the cumulative prevalence was 0.75% (95% confidence interval: 0.52-0.97) in the total sample and 0.92% (95% confidence interval: 0.62-1.21) among the responders.The cumulative prevalence was higher than in other studies combining the results of a survey with register data. The point prevalence was underestimated due to low participation rate in the clinical examination and remission among the participants.

Abstract
AIM The aim of this study was to estimate the prevalence of rheumatoid arthritis (RA) in the eastern Black Sea region of Turkey. METHOD The study was carried out between March 2003 and March 2005 by the Karadeniz Technical University Medical Faculty Department of Physical Medicine and Rehabilitation in the urban area in the eastern Black Sea region of Turkey, which has a population of 459021 (according to the 2000 national census). A total of 6103 subjects, 20 years old or over, were selected by the sampling method; 3023 (49.5%) women and 3080 (50.5%) men were included in the study. The diagnosis of RA was performed based on fulfilling the American College of Rheumatology (ACR) criteria. RESULTS Fifty-nine patients were diagnosed with RA according to the ACR criteria, of which 11 were male and 48 female. The prevalence of RA was 1% (95% CI: 0.75-1.25) in the general population, 1.6% (95% CI: 1.15-2.05) in women and 0.35% (95% CI: 0.14-0.56) in men. The female/male ratio was 4.3 : 1.0, showing that RA prevalence was statistically significantly higher in women (P <0.005). CONCLUSION Our study demonstrates that RA is a common disease in Turkish society.

Abstract
Previous studies have estimated a prevalence of a broad grouping of autoimmune diseases of 3.2%, based on literature review of studies published between 1965 and 1995, and 5.3%, based on national hospitalization registry data in Denmark. We examine more recent studies pertaining to the prevalence of 29 autoimmune diseases, and use these data to correct for the underascertainment of some diseases in the hospitalization registry data. This analysis results in an estimated prevalence of 7.6-9.4%, depending on the size of the correction factor used. The rates for most diseases for which data are available from many geographic regions span overlapping ranges. We also review studies of the co-occurrence of diseases within individuals and within families, focusing on specific pairs of diseases to better distinguish patterns that may result in insights pertaining to shared etiological pathways. Overall, data support a tendency for autoimmune diseases to co-occur at greater than expected rates within proband patients and their families, but this does not appear to be a uniform phenomenon across all diseases. Multiple sclerosis and rheumatoid arthritis is one disease pair that appears to have a decreased chance of coexistence.

Abstract
Objective of the present study is aimed to determine costs of rheumatoid arthritis (RA) based on reimbursement agencies perspective [Social Security Institution (SSI)] in Turkey. The international clinical guidelines for RA are followed for analysing the direct costs. Data were collected from hospital bills, social security institution price lists, and Ministry of Health drug price list. Direct costs of RA patients were estimated as euro 2,669.14 patient/year. Outpatient costs were found to be euro 240.40. Routine tests during the year were calculated as euro 98.85. Ten percent of patients are hospitalized per year, and 0.62% of these patients received arthroplasty and/or other interventions. The cost during hospital stay was euro 87.76. euro 2,238 was determined as being paid per year for medication alone (including anti-TNF) and euro 4 is spent on auxiliary materials annually. Our data show a remarkable economic impact of RA over society. We hope that the cost of RA studies will help package price practices for reimbursement agencies.

Abstract
The epidemiology of rheumatic musculoskeletal (MSK) disorders in the developing world is much less well known than it is in the developed world. We expect ethnicity, traditions, socioeconomics and lifestyles to have an impact, but overall data are sparse. This report focuses on the WHO-ILAR COPCORD (community-oriented programme for control of rheumatic diseases). COPCORD was designed to collect community data on pain and disability in the developing economies. Several countries in Asia-Pacific and Central South America have completed COPCORD surveys. Despite some limitations in methodology, COPCORD provides a fair estimate of the spectrum and extent of rheumatic MSK disorders. We digress from a general overview to highlight the scenario for rheumatoid arthritis, and draw a few parallels with known statistics from the developed world. Overall, the emerging spectrum and severity are not very different, but in the developing countries the burden of disease, worsened by dismal rheumatology services, is likely to be staggering.

Abstract
Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are chronic, progressive, systemic inflammatory rheumatic diseases that lead to serious disability. The objective of this study was to investigate the demographic and clinical characteristics of the patients with RA and AS who were treated in tertiary hospitals in Turkey and to analyze their current medical management. A total of 562 RA and 216 AS patients were evaluated. The mean age of RA patients was 52.1 +/- 12.6 years. The female to male ratio was 3.7:1. Of the RA patients, 72.2% had positive rheumatoid factor (RF), 62.9% had high C-reactive protein, and 75.2% had radiological erosion. The ratio of patients with Disease Activity Score (DAS) 28 >3.2 was 73.9% and of those with Health Assessment Questionnaire (HAQ) > or =1.5 was 20.9%. There was a statistically significant increase in RF positivity and HAQ scores in the group with higher DAS 28 score. Frequency of extraarticular manifestations was 22.4%. The ratio of the patients receiving disease modifying antirheumatic drugs (DMARD) was 93.1%, and 6.9% of the patients were using anti-tumor necrosis factor (TNF) blocking agents. In AS, the mean age of the patients was 38.1 +/- 10.6, and the female to male ratio was 1:2.5. The time elapsed between the first symptom and diagnosis was 4.3 years. The ratio of peripheral joint involvement was 29.4%. Major histocompatibility complex, class I, B 27 was investigated in 31.1% of patients and the rate of positivity was 91%. In 52.4% of the patients, Bath AS Disease Activity Index (BASDAI) was > or =4. The erythrocyte sedimentation rate, Bath AS Functional Index, and peripheral involvement were significantly higher in the group with BASDAI > or =4. Frequency of extraarticular involvement was 21.2% in AS patients. In the treatment schedule, 77.5% of AS patients were receiving sulphasalazine, 15% methotrexate, and 9.9% anti-TNF agents. Despite widespread use of DMARD, we observed high disease activity in more than half of the RA and AS patients. These results may be due to relatively insufficient usage of anti-TNF agents in our patients and therefore these results mostly reflect the traditional treatments. In conclusion, analysis of disease characteristics will inform us about the disease severity and activity in RA and AS patients and could help in selecting candidate patients for biological treatments.
