“…Oligoarthritis accounted for about 40%of JIA cases in France [7], 50% in United Kingdom [8,9] and 54% in Estonia [11]. Not only in European countries but also in other continents, oligoarthritis is the most common JIA category among Caucasians [12].…”

“…The HLA-B27 antigen was found in approximately 16% of the population of northern Norway, Sweden, and Finland [22]. In two other population-based studies of HLA-B27 occurrence in patients with JIA, 28.6% of patients were positive for the antigen in Estonia [23] and 42% in northern Norway [24]. Among 228 patients with JIA studied in Taiwan, an HLA-B27 association was revealed in 55.2% [25].…”

Human Leukocyte Antigen B27 and Juvenile Idiopathic Arthritis and Classification of Juvenile Spondyloarthropathies by the Assessment of SpondyloArthritis International Society Criteria

Objective. We examined the clinical relationship between human leukocyte antigen B27 (HLA-B27) and juvenile idiopathic arthritis (JIA). Additionally, we assessed the usefulness of the Assessment of SpondyloArthritis International Society (ASAS) criteria for diagnosing juvenile spondyloarthropathies (SpA). Methods. We retrospectively reviewed medical records of 239 patients with JIA classified according to the International League of Associations for Rheumatology (ILAR) classification to analyze the features of the joint involvement site. Results were correlated with the presence of HLA-B27. After that, we classified the 239 JIA patients according to the ASAS criteria to diagnose juvenile SpA. The relationship between the ASAS criteria and a diagnosis of juvenile SpA was analyzed by a chi-squared test. Results. Back pain was associated with HLA-B27 in boys (p=0.002) but not in girls (p=0.616). In both sexes, involvement of the small joints in the lower extremities was highly associated with HLA-B27 (p=0.001 for boys, p=0.021 for girls). In addition, HLA-B27 was associated with enthesitis (p=0.004 for boys, p=0.021 for girls). Eighty-seven (36.4%) patients with JIA fulfilled the ASAS criteria; 2 (0.8%) had axial SpA and 85 (35.6%) had peripheral SpA. HLA-B27 was the most significant factor for diagnosing juvenile SpA (sensitivity 80%, specificity 99.31%, positive likelihood ratio, 116). Conclusion. The ILAR criteria have some weaknesses for diagnosing HLA-B27-positive JIA patients in early stages. The use of the ASAS criteria for juvenile patients will enable pediatric rheumatologists to diagnose juvenile SpA patients earlier.

“…International data concerning morbidity are very divergent, the publications have presented a gradient of morbidity between the North and South of Europe [15]. In Norway, morbidity per 100,000 inhabitants amounted to 14 in 2008, in Spain to 7 in 2010, in Estonia to 22 in 2007, and in the Czech Republic to 13 in 2006 [17,18], in France -19.8, whereas in US and in Sweden -86.1, and in Australia -440, much more than in Poland [4,13].…”

“…The number of patients per 100,000 inhabitants in Spain amounted to 40, which was similar to Poland, whereas in Estonia it amounted to 84, and in the Czech Republic to 140. Pruunsild et al stipulate for Estonia in 1998-2000 the indicator with a value of 21.7 -19.3 for boys, and 22.9 for girls [15]. Studies from Scandinavian countries state that this indicator amounted to 15 per 100,000 [16].…”

Objective. The aim of this study was to investigate the juvenile idiopathic arthritis (JIA) morbidity rate in the Polish population, calculated per 1,000 inhabitants of a given province, taking into account the differences between urban and rural areas, gender and area of residence (province) 2008-2012. Method. From the NFZ IT systems information was obtained on the treatment of patients who had M08 and M09 juvenile arthritis, diseases classified elsewhere by the ICD-10 diagnosis code in the settlement report of the hospital. The number of patients, their gender and age at individual diagnoses were calculated based on the PESEL number provided in the statistical reports of the patient with the analysed ICD-10 diagnosis. Urban and rural cases were compared using commune zip codes. The basic for classifying the patient as a member of a urban or rural population was the zip code of the declared place of residence. Results. In Poland, the number of patients suffering from juvenile idiopathic arthritis has been increasing since 2008 -from 9.2 thousand in 2008 to 11.4 thousand in 2012. The majority were girls (approx. 62%). Most patients were living in urban areas; in 2008, 5.9 thousand: urban areas -64% of women and 36% of men; 3.2 thousand: rural areas -62% of women, 38% of men); in 2012, 7.2 thousand -urban areas); 4.2 thousand -rural areas. The morbidity indicators ranged from 0.195 -0.357 per 1,000 inhabitants, depending on the year, gender and place of residence (province and commune).
