Abstract
OBJECTIVE To estimate the prevalence of psoriatic arthritis (PsA), axial spondyloarthritis (axSpA) and rheumatoid arthritis (RA) and the use of biologic agents in these diseases in Norway. METHODS From the Norwegian Patient Registry (NPR), we identified as PsA, axSpA and RA patients ≥18 years those with ≥2 recorded episodes with diagnostic coding for index disease (L40.5, M07.0-M07.3 for PsA; M45, M46.0, M46.1, M46.8 and M46.9 for axSpA; M05-M06 for RA). We calculated the point prevalence of PsA, axSpA and RA as per the 1st of January 2017 in the Norwegian adult population (age ≥18). Dispensed disease-modifying antirheumatic drug (DMARD) prescriptions were obtained from the Norwegian Prescription Database and biologic DMARDs given in hospitals from the NPR. RESULTS The point prevalence of PsA, axSpA, RA, and any of these diseases in total was 0.46%, 0.41%, 0.78%, and 1.56%, respectively. Among women, the prevalence of PsA, axSpA, and RA was 0.50%, 0.37%, and 1.10%, and among men 0.43%, 0.45%, and 0.46%, respectively. In 2017, 27.3% of RA patients, 25.7% of PsA patients and 35.1% of axSpA patients used biologic DMARDs. Treatment with biologics was more frequent in younger age groups in all three diseases, and became more infrequent especially after age ≥55 years. CONCLUSION In Norway, the combined prevalence of PsA, axSpA, and RA was over 1.5%. Reflecting the good overall access to highly effective but costly biologic treatments, more than a fourth of these patients used biologic agents, which corresponds to over 0.4% of Norwegian adult population.

Abstract
Social networks are associated with individual's health and well-being. Working life offers opportunities to create and maintain social networks, while retirement may change these networks. This study examined how the number of ties in social network changes across the retirement transition. The study population consisted of 2319 participants (84% women, mean age 63.2 years) from the Finnish Retirement and Aging study. Information about social network ties, including the number of ties in the inner, middle and outer circles of the social convoy model, was gathered using annual postal surveys before and after retirement. Three repeat surveys per participant covered the retirement transition and the post-retirement periods. Mean number of network ties was 21.6 before retirement, of which 5.6 were situated in the inner, 6.9 in the middle and 9.1 in the outer circle. The number of ties in the outer circle decreased by 0.67 (95% CI - 0.92, - 0.42) during the retirement transition period, but not during the post-retirement period (0.11, 95% CI - 0.33, 0.12) (interaction period * time, p = 0.006). The pattern of change in these ties did not differ by gender, occupational status, marital status, number of chronic diseases and mental health during the retirement transition period. The number of ties in the inner and middle circles overall did not decrease during these periods. The number of peripheral relationships decreased during the retirement transition but not after that, suggesting that the observed reduction is more likely to be associated with retirement rather than aging.

Abstract
The aim is to examine whether characteristics of social relationships predict extended employment beyond the pensionable age among Finnish public sector workers. The study population consisted of 4014 participants (83% women, age 62.56 ± 1.21) of the Finnish Retirement and Aging Study followed between 2014 and 2019. Extended employment was defined as the difference between actual retirement date and individual age-related pensionable date and classified into three groups: no extension (retired on pensionable age or extended by < 3 months), short extension (3 months–< 1 year), and long extension (≥ 1 year) beyond the pensionable date. Characteristics of social relationships and engagement were assessed 18 months prior to the pensionable date. Social engagement was classified into consumptive social participation, formal social participation, informal social participation, and other social participation. Data were analyzed using multinomial regression analysis. Of total study participants, 17.8% belonged to short- and 16.5% belonged to long-extension group. Adjusted for age, occupational status, self-rated health and depression, and having a working spouse (OR 2.34, 95% CI 1.39–3.95) were associated with long extension of employment beyond the pensionable age when compared to no extension among men. Likewise, among women, living alone (OR 1.60, 95% CI 1.28–2.00), having a working spouse (1.85, 1.39–2.45), and high consumptive (1.32, 1.07–1.65), high formal (1.47, 1.17–1.85), and other social participation (0.79, 0.63–0.98) were associated with long extension. Having a working spouse, living alone, and high consumptive social participation were associated with short extension. Several characteristics of social relationships, such as having a working spouse, living alone, and high frequency of social engagement, predicted an extension of employment beyond the pensionable age.

Abstract
Background:RA is traditionally described as a symmetric polyarthritis. The ACR/EULAR 2010 criteria are met if patient has high positive ACPA, symptoms >=6 wks and one small joint swollen. The public and all steps of health care have been informed for many years that RA should be found early.Objectives:To study variations in pattern on first presentation of RA.Methods:All patients with the new diagnosis of RA were extracted from the GoTreatIT clinical database between 2008 to 2019 at a single RA clinic that covers a population of 250.000. Demographic data, clinical variables, labs, x-rays, joint status and PROs at baseline were included in the analysis. Appropriate parametric/non-parametric tests were used to study differences between groups.Results:A total of 1044 (73.5% CCP+) patients with no prior diagnosis of RA were included; 683 (65%) female, mean age 56; 361 (35%) male, mean age 61. At initial presentation in 2008, 60% had >=6 swollen joints (Figure) and a mean DAS28 of 4.4 compared to 22% and 3.8 respectively, in 2019 (p<0.007). Duration of symptoms prior to diagnosis decreased from 6 to 4 months (p=0.033), and the proportion of patients with erosions from 20% in 2008 to 14% in 2019 (ns). Symptoms (PROs) such as pain, fatigue and global health were similar/slightly worse in 2019 compared to 2008.Conclusion:RA cannot be marketed as “symmetric polyarthritis”, as more than half of the patients have a maximum of 2 swollen joints at the time of the diagnosis at the most recent years. Patients with RA can be identified earlier, with less disease activity and damage, compared to previous years.Figure:Disclosure of Interests:None declared

Abstract
Purpose: To assess the significance of ultrasonography (US) in detecting hip joint synovitis in patients with rheumatic diseases. Material and Methods: Forty patients with rheumatic disease and suspected hip joint synovitis underwent MRI and US of the hip joint. In addition to the throughout MRI evaluation, the anterior collum-capsule distance (CCD) was determined by both MRI and US. Thirteen healthy volunteers were examined with MRI to establish the criteria for normal findings in MRI when classifying hip joints to those with synovitis and those without. MRI was used as a gold standard. Results: Synovitis was found using MRI in 31 hips of 22 patients (9 patients had bilateral synovitis). The intraclass correlation was 0.61 between MRI and US in measuring CCD. In classifying hip joint synovitis with US, the sensitivity of the method was 87% and specificity 42%, when the CCD criterion for synovitis was determined to be ≥7 mm. If the cut-off point was raised to 9 mm, the sensitivity decreased to 61% while specificity increased to 94%. A difference in CCD of ≥1 mm between the hips as an additional criterion for synovitis increased the number of false-positive findings. Conclusion: Measurement of CCD with US proved to be a rather inaccurate method to point out synovitis in rheumatic patients when using MRI as a reference. The main reason for this result was the thickened capsule, which US could not differentiate from a thickened synovium.

Abstract
UNLABELLED Maximal walking speed and quantitative ultrasound index (QUI) were significant and independent predictors of hip fracture among subjects aged ≥ 55 years. A model including readily available variables along with simple fall-related factors may be clinically useful in the assessment of hip fracture risk even without a QUI measurement. INTRODUCTION This study assessed fall-related risk factors along with heel bone quantitative ultrasound (QUS) measurements for the prediction of hip fracture during a mean follow-up of 9.8 years in a nationally representative population sample. METHODS The study population consisted of 2,300 subjects (1,331 women and 969 men) aged 55 years or over, who had participated in a comprehensive health survey in 2000-2001. Information on the subjects’ health and fall-related risk factors was obtained with interviews, questionnaires and tests carried out by specially trained professionals. QUS measurements were made by means of the Hologic Sahara device. First emerging cases of hip fracture were identified from the National Hospital Discharge Register. RESULTS During the follow-up, 96 subjects sustained a hip fracture. Slow maximal walking speed, low quantitative ultrasound index (QUI), high age, tallness, short waist circumference, Parkinson's disease and the number of central nervous system active medication were significant and independent predictors of hip fracture. The model including all of these risk factors explained 68 % of the variation in hip fracture risk. Excluding QUI from this model reduced the percentage to 66%. CONCLUSIONS Maximal walking speed and QUI were significant and independent predictors of hip fracture. A model including readily available variables such as age, gender, height and waist circumference along with simple fall-related factors may be of clinical use in the assessment of hip fracture risk even without a QUS measurement.

SUMMARY Adjusted for age, gender, height and weight, calcaneal quantitative ultrasound (QUS) and serum 25-hydroxyvitamin D (S-25(OH)D) proved to be significant predictors of hip fracture among subjects aged ≥50 years. Even if their contribution to the predictive power was modest, they may be useful in the assessment of hip fracture risk in the elderly. INTRODUCTION This study assessed calcaneal QUS measurements, S-25(OH)D and several other factors for the prediction of hip fracture risk in a nationally representative population sample. METHODS The study population consisted of 3,305 subjects (1,872 women), aged 50 years or over, who had participated in a comprehensive health survey. QUS measurements were made by means of the Hologic Sahara device. S-25(OH)D was measured by radioimmunoassay. Emerging cases of hip fracture were identified from the National Hospital Discharge Register. RESULTS During a mean follow-up of 8.4 years, 95 subjects sustained a hip fracture. After adjusting for age, gender, height, weight and each other, a 1 standard deviation increment in the quantitative ultrasound index (QUI) (21.7) and in S-25(OH)D (17.5 nmol/L) reduced the risk of hip fracture by 40 % (hazard ratio [HR] = 0.60, 95 % confidence interval [CI] = 0.42-0.86) and by 31 % (HR = 0.69, 95 % CI = 0.55-0.87), respectively. The predictive power of a model including age, gender, height and weight was improved by about 8 % after the addition of QUI and S-25(OH)D. Among subjects aged 75 years or over, the corresponding improvement was about 130 %. CONCLUSIONS QUI and S-25(OH)D were significant and independent predictors of hip fracture. However, their ability to increase the predictive power of a statistical model including readily available simple variables such as age, gender, height and weight was rather modest. Still, our findings suggest that QUI and S-25(OH)D may be of clinical use in the assessment of hip fracture risk particularly in the elderly.

Abstract
Objective:
The main objective was to compare the cost-effectiveness of therapeutic options in moderate or severe rheumatoid arthritis (RA) when a clinical response to a first TNF-blocker, either etanercept (ETA), adalimumab (ADA), or infliximab (INF), is insufficient. Methods:
Effectiveness criteria were defined as remission (RS), low disease activity (LDAS), and moderate to high disease activity (MHDAS). Cost-effectiveness was derived as cost per day in RS and in LDAS using simulation modelling to assess six sequential biologic strategies over 2 years. Each sequential treatment strategy was composed of three biologic agents and included a first anti-TNF agent, ETA, ADA or INF, followed by either abatacept (ABA) or rituximab (RTX) as a second therapeutic option in case of an insufficient response, followed by another anti-TNF agent in case of further insufficient response. Results:
Over two years and taking into account biologic costs, the following estimated mean costs per day in RS and LDAS were respectively of €829 and €428 for the biologic sequence composed of ADA-ABA-ETA, €1292 and €516 for the sequence ADA-RTX-ETA, €829 and €429 for the sequence ETA-ABA-ADA, €1292 and €517 for the sequence ETARTX- ADA, €840 and €434 for the sequence INF-ABA-ETA, and €1309 and €523 for the sequence INF-RTX-ETA. Conclusion:
The treatment sequences including ABA as the second biologic option appear more cost-effective than those including RTX in a patients with moderate to severe RA and an insufficient response to a first anti-TNF agent.

Abstract
UNLABELLED Hip fracture risk was assessed according to parity among postmenopausal women. Compared with nulliparous women, the fracture risk was lower in women with three or more births. INTRODUCTION Parity was assessed for long-term prediction of hip fracture in postmenopausal women. METHODS Postmenopausal women (n= 2,028) aged 45 or over with no history of hip fracture were studied. From 1978 to 1980, all of them had participated in a comprehensive health survey based on a nationally representative population sample. Emerging cases of hip fracture were identified from the National Hospital Discharge Register during a follow-up period extending up to 17 years. RESULTS The risk of hip fracture was lower among parous women compared with nulliparous women. The model adjusted for age showed a significant inverse association between parity as a continuous variable and the risk of hip fracture [RR = 0.74; 95% confidence interval (CI), 0.61-0.90] per an increment of one standard deviation (2.4 births). Adjusted for age, menopausal age, level of education, body mass index, vitamin D status, alcohol consumption, smoking history, leisure time physical activity, and self-rated health, the relative risk was 0.50 (95% CI, 0.32-0.79) for women with three or more births and 0.85 (95% CI, 0.55-1.32) for women with one to two births as compared with nulliparous women. CONCLUSION Parity, three or more births in particular, predicts a lowered risk of hip fracture in the long run.

Abstract
OBJECTIVE To study the effect of isometric neck strength exercises on upper cervical stability in patients with rheumatoid arthritis (RA). METHODS Twenty patients with a mean (SD) age of 58 (9) years and duration of RA of 27 (10) years volunteered for the study. Lateral radiographs of the cervical spine were taken to measure the current atlantoaxial distance (AAD) in flexion and extension. Maximal isometric neck flexion and extension strength values were measured by a dynamometer. Thereafter, AADs were measured from radiographs taken at 80-90% resistance of maximal strength. RESULTS According to the full flexion radiographs at baseline, the patients were classified into three groups: eight patients without anterior atlantoaxial subluxation (aAAS) [AAD = 2.1 (2-3) mm], seven with unstable aAAS [AAD = 6.6 (5-8) mm], and five with stable aAAS [AAD = 5.5 (5-7) mm]. During resisted flexion the AAD decreased by 5 (3-7) mm (p<0.001) in the unstable aAAS group, while in the other two groups the changes were minor. During resisted extension the AAD increased by 3 (2-6) mm (p<0.001) in the cases with unstable aAAS only. CONCLUSION Isometric exercising towards flexion decreases the AAD in cases with unstable aAAS. Submaximal loading of the neck extensors by pushing the back of the head against the resistance even in the neutral position of the cervical spine leads to a decrease in the width of the cervical spine canal and is not recommended in unstable aAAS.

Abstract
We studied the extent to which exocrine dysfunction of the pancreas is seen among patients with severe chronic polyarthritis and whether it might account for some gastrointestinal symptoms. Our series consisted of 50 such chronic polyarthritis cases; most had rheumatoid arthritis but had neither diagnosed or suspected pancreatitis nor primary Sjögren's syndrome. They were asked about gastrointestinal (GI) and sicca symptoms. The exocrine function of each pancreas was evaluated by the fecal elastase-1-enzyme test. Thirty-two patients had GI symptoms at least weekly. Forty had sicca eye syndrome and 26 had dry mouth. There were two cases (4%; 95% confidence interval, 1-14%) with abnormally low fecal elastase-1-enzyme test level. Chronic GI and sicca symptoms are frequent among patients with severe chronic polyarthritis. Secondary Sjögren's syndrome may cause exocrine insufficiency in the pancreas. That circumstance was not common here, but it is worth remembering because it can be diagnosed by a noninvasive method, and enzyme preparation treatment is available for the symptoms, especially for postprandial pain and distention of the stomach.

Abstract
Several studies have identified the PTPN22 allelic variant 1858 C/T that encodes the R620W amino-acid change as a putative susceptibility factor in autoimmune diseases. The current study was undertaken to examine a large cohort of Finnish rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) subjects using both population control and, importantly, family-based association methods. The latter is particularly important when, as is the case for the 1858 C/T polymorphism, the frequency of the variant allele (T) differs in both major ancestral populations and in subpopulations. The analysis of rheumatoid factor-positive 1030 RA probands from Finland provides strong support for association of this variant in both population studies (allele specific odds ratio (OR)=1.47, 95% confidence interval (CI)=1.27-1.70, P=3 x 10(-7)) and in family studies (P<10(-6)). In contrast, no allelic association was seen with JIA (230 probands) and only weak evidence for a genotypic effect of 1858T homozygotes was observed in this population.

Abstract
OBJECTIVE To study the prevalence of cervical spine subluxation in patients with rheumatoid arthritis waiting for orthopaedic surgery, and symptoms that might be associated with the disorders. METHODS 194 patients with rheumatoid arthritis were referred for orthopaedic surgery at Jyväskylä Central Hospital, 154 (79%) of whom volunteered for the present study including clinical examination, laboratory tests, radiographs of the cervical spine, hands, and feet, and self report questionnaires. Definition of anterior atlantoaxial subluxation (aAAS) was >3 mm and of subaxial subluxation (SAS)>or=3 mm. Atlantoaxial impaction (AAI) was analysed following to the Sakaguchi-Kauppi method. RESULTS 67 patients (44%) had cervical spine subluxation or previous surgical fusion. The prevalence of aAAS, AAI, SAS, or previous fusion was 27 (18%), 24 (16%), 29 (19%), and 8 (5%), respectively; 69% of patients with cervical spine subluxations (those with fusions excluded) reported neck pain, compared with 65% of patients without subluxations (p=0.71). The prevalence of occipital, temporal, retro-orbital, and radicular pain in upper extremities was similar in patients with or without cervical spine subluxations (54% v 43%; 17% v 31%; 25% v 24%; 47% v 48%, respectively). However, patients with subluxations were older, had longer disease duration, more active disease, poorer function according to the Health Assessment Questionnaire, and had more often erosive disease. CONCLUSIONS Asymptomatic cervical spine subluxation is common in patients with rheumatoid arthritis waiting for orthopaedic surgery. Regardless of symptoms, the possibility of cervical spine subluxation in patients with severe rheumatoid arthritis should be considered in preoperative evaluation.

Abstract
OBJECTIVE To determine the influence of HLA-B27 homozygosity and HLA-DRB1 alleles in the susceptibility to, and severity of, ankylosing spondylitis in a Finnish population. METHODS 673 individuals from 261 families with ankylosing spondylitis were genotyped for HLA-DRB1 alleles and HLA-B27 heterozygosity/homozygosity. The frequencies of HLA-B27 homozygotes in probands from these families were compared with the expected number of HLA-B27 homozygotes in controls under Hardy-Weinberg equilibrium (HWE). The effect of HLA-DRB1 alleles was assessed using a logistic regression procedure conditioned on HLA-B27 and case-control analysis. RESULTS HLA-B27 was detected in 93% of cases of ankylosing spondylitis. An overrepresentation of HLA-B27 homozygotes was noted in ankylosing spondylitis (11%) compared with the expected number of HLA-B27 homozygotes under HWE (4%) (odds ratio (OR) = 3.3 (95% confidence interval, 1.6 to 6.8), p = 0.002). HLA-B27 homozygosity was marginally associated with reduced BASDAI (HLA-B27 homozygotes, 4.5 (1.6); HLA-B27 heterozygotes, 5.4 (1.8) (mean (SD)), p = 0.05). Acute anterior uveitis (AAU) was present in significantly more HLA-B27 positive cases (50%) than HLA-B27 negative cases (16%) (OR = 5.4 (1.7 to 17), p<0.004). HLA-B27 positive cases had a lower average age of symptom onset (26.7 (8.0) years) compared with HLA-B27 negative cases (35.7 (11.2) years) (p<0.0001). CONCLUSIONS HLA-B27 homozygosity is associated with a moderately increased risk of ankylosing spondylitis compared with HLA-B27 heterozygosity. HLA-B27 positive cases had an earlier age of onset of ankylosing spondylitis than HLA-B27 negative cases and were more likely to develop AAU. HLA-DRB1 alleles may influence the age of symptom onset of ankylosing spondylitis.

Abstract
OBJECTIVE To describe the functional capacity for daily activities in old people with clinical rheumatoid arthritis (including juvenile rheumatoid arthritis (JRA)) in a population based cohort. METHODS A cohort of 700 people was randomly collected from the population older than 75 years in a Finnish town. Altogether 601 persons (86%) participated. Data were collected from clinical records and by interview, clinical examination, and questionnaire. Ability to carry out activities of daily living (ADL) was assessed by the Barthel index, and the IADL (instrumental activities of daily living) by the Lawton and Brody questionnaire. RESULTS 16 people had clinical rheumatoid arthritis (one with JRA). The prevalence was 16/601 (2.7% (95% confidence interval, 1.7% to 4.5%)). Eight patients with rheumatoid arthritis (50%) obtained the best possible ADL figures, while three (19%) had very poor results. Seven (44%) could not dress themselves without help. Three (19%) were unable to walk, and five (31%) could not climb stairs. Sex and age adjusted results showed no statistical difference (ADL and IADL) between patients with clinical rheumatoid arthritis and rest of the cohort. Four patients (25%) had dementia, which was associated with the poor functional capacity. CONCLUSIONS The prevalence of the disease was unexceptional. The ability of old people with rheumatoid arthritis to carry out activities of daily living did not differ from the general population, but the disease may lead to severe disability on an individual level, especially when associated with dementia. It therefore remains a considerable challenge to the health care and social systems.

Abstract
We have developed and validated a semi-automated fluorescent method of genotyping human leucocyte antigen (HLA)-DRB1 alleles, HLA-DRB1*01-16, by multiplex primer extension reactions. This method is based on the extension of a primer that anneals immediately adjacent to the single-nucleotide polymorphism with fluorescent dideoxynucleotide triphosphates (minisequencing), followed by analysis on an ABI Prism 3700 capillary electrophoresis instrument. The validity of the method was confirmed by genotyping 261 individuals using both this method and polymerase chain reaction with sequence-specific primer (PCR-SSP) or sequencing and by demonstrating Mendelian inheritance of HLA-DRB1 alleles in families. Our method provides a rapid means of performing high-throughput HLA-DRB1 genotyping using only two PCR reactions followed by four multiplex primer extension reactions and PCR-SSP for some allele groups. In this article, we describe the method and discuss its advantages and limitations.

Abstract
OBJECTIVE To evaluate the validity and reliability of the Finnish version of the Arthritis Impact Measurement Scales (AIMS2) in Finnish patients with rheumatoid arthritis (RA). METHODS The reliability of the Finnish AIMS2 (Finn-AIMS2) questionnaire was assessed by test retest procedure and internal consistency of health-status scales. Construct validity was assessed by factor analysis, and convergent validity by correlation coefficients, with several disease activity and functional status variables. RESULTS Internal consistency was 0.79-0.89 and test retest reliability 0.72-0.97. Factor analysis identified three factors: physical, psychosocial, and pain. There were strong correlations between the Finn-AIMS2 health-status scales and the Health Assessment Questionnaire (HAQ). CONCLUSION The Finn-AIMS2 questionnaire is a reliable and valid instrument for measuring health status in middle-aged Finnish patients with RA. The results also support the applicability of AIMS2 in comparisons in multinational studies.

Abstract
OBJECTIVES To determine whether genetic polymorphisms in or near the transforming growth factor beta1 (TGFB1) locus were associated with susceptibility to or severity of ankylosing spondylitis (AS). METHODS Five intragenic single-nucleotide polymorphisms (SNP) and three microsatellite markers flanking the TGFB1 locus were genotyped. Seven hundred and sixty-two individuals from 184 multiplex families were genotyped for the microsatellite markers and two of the promoter SNPs. One thousand and two individuals from 212 English and 170 Finnish families with AS were genotyped for all five intragenic SNPs. A structured questionnaire was used to assess the age of symptom onset, disease duration and disease severity scores, including the BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) and BASFI (Bath Ankylosing Spondylitis Functional Index). RESULTS A weak association was noted between the rare TGFB1 +1632 T allele and AS in the Finnish population (P = 0.04) and in the combined data set (P = 0.03). No association was noted between any other SNPs or SNP haplotype and AS, even among those families with positive non-parametric linkage scores. The TGFB1 +1632 polymorphism was also associated with a younger age of symptom onset (English population, allele 2 associated with age of onset greater by 4.2 yr, P = 0.05; combined data set, allele 2 associated with age of onset greater by 3.2 yr, P = 0.02). A haplotype of coding region SNPs (TGFB1 +869/+915+1632 alleles 2/1/2) was associated with age of symptom onset in both the English parent-case trios and the combined data set (English data set, haplotype 2/1/2 associated with age of onset greater by 4.9 yr, P = 0.03; combined data set, haplotype 2/1/2 associated with greater age of onset by 4.2 yr, P = 0.006). Weak linkage with AS susceptibility was noted and the peak LOD score was 1.3 at distance 2 cM centromeric to the TGFB1 gene. No other linkage or association was found between quantitative traits and the markers. CONCLUSION This study suggests that the polymorphisms within the TGFB1 gene play at most a small role in AS and that other genes encoded on chromosome 19 are involved in susceptibility to the disease.

Abstract
OBJECTIVES To examine whether functional radiography and functional magnetic resonance imaging (MRI) are equally efficient in detecting the extent of unstable anterior atlantoaxial subluxation (aAAS) in rheumatic patients. METHODS 23 patients with unstable aAAS (diagnosed by functional radiography) were examined by functional MRI because of a neck symptom. Twenty two patients had rheumatoid arthritis and one had juvenile idiopathic arthritis. aAAS was diagnosed if the anterior atlantoaxial diameter (AAD) was >3 mm and was considered unstable if the AAD differed by >2 mm between flexion and extension radiographs. The AAD was measured from radiographs (flexion and extension) and MRI images (flexion and neutral). RESULTS The extent of aAAS during flexion measured by radiography was greater than that found by MRI in all 23 patients (mean difference 3 mm (95% confidence interval 2 to 4)). In four (17%) patients flexion MRI could not demonstrate aAAS detected by radiography. The difference between the AAD measurements during flexion by these two methods was substantial (that is, >or=4 mm) in nine (39%) cases. Severe aAAS (>or=9 mm) was seen in 15 (65%) patients by functional radiography and in four (17%) by functional MRI. CONCLUSIONS The magnitude of aAAS was often substantially smaller when measured by functional MRI rather than by functional radiography. Thus one cannot rely on the result of functional MRI alone; functional radiographs are needed to show the size of unstable aAAS. The maximal extent of the subluxation must be taken into account when the possible compression of neural structures is evaluated by MRI.

Abstract
OBJECTIVE The rarity of reports on extended multiplex families points out that the genetic component in juvenile idiopathic arthritis (JIA) might not be particularly strong. Our objective was to determine the frequency of chronic inflammatory rheumatic diseases among the parents who had two or more offspring affected by JIA. METHODS During the last 17 years patients with JIA treated at the Rheumatism Foundation Hospital in Heinola and their parents have been systematically asked about the familial occurrence of rheumatic diseases. A total of 45 families with more than one sibling affected by JIA were found among about 2,300 JIA cases. In these "multicase families", 9 parents from 8 families also had a diagnosis of chronic inflammatory rheumatic disease. Their case histories were studied. RESULTS Four of the parents had had JIA (one subsequently developed ankylosing spondylitis), and 4 had rheumatoid factor-negative chronic arthritis (one had also had chronic iritis since the age of 10, resembling that seen in JIA). Three of them had features of JIA and only one met the classification criteria for rheumatoid arthritis. One had ankylosing spondylitis. CONCLUSIONS Since the expected number of JIA cases among the 90 parents was about 0.2, there was drastic increase in JIA frequency among the parents in families with multiple offspring also affected by JIA. These results suggest that JIA susceptibility genes may likely be clustered in these families.

Abstract
OBJECTIVE To evaluate whether cervical spine changes are associated with the destruction of shoulder or peripheral joints and with bone mineral density (BMD) in patients with long-term RA. METHODS An inception cohort of 67 patients with seropositive and erosive RA were followed up for 20 years. Cervical spine, shoulder, hand and foot radiographs, and the BMD of the lumbar spine and femoral neck were evaluated. RESULTS A positive relationship was detected between the occurrence of atlantoaxial disorders and the destruction of both shoulder (p < 0.001) and peripheral (p = 0.001) joints. In addition, the severity of anterior atlantoaxial subluxation and atlantoaxial impaction positively correlated with the grade of destruction in the evaluated joints. Furthermore, patients with atlantoaxial disorders presented decreased BMD of the femoral neck (p = 0.019). The occurrences of subaxial subluxations (SAS) and subaxial disc space narrowings only associated with higher onset age of RA. CONCLUSIONS Patients with severe RA and osteoporosis have an increased risk for atlantoaxial disorders. The co-existence of shoulder destruction and cervical spine disorders makes the differential diagnosis of shoulder and neck pain challenging.

Abstract
PURPOSE To assess the significance of ultrasonography (US) in detecting hip joint synovitis in patients with rheumatic diseases. MATERIAL AND METHODS Forty patients with rheumatic disease and suspected hip joint synovitis underwent MRI and US of the hip joint. In addition to the throughout MRI evaluation, the anterior collum-capsule distance (CCD) was determined by both MRI and US. Thirteen healthy volunteers were examined with MRI to establish the criteria for normal findings in MRI when classifying hip joints to those with synovitis and those without. MRI was used as a gold standard. RESULTS Synovitis was found using MRI in 31 hips of 22 patients (9 patients had bilateral synovitis). The intraclass correlation was 0.61 between MRI and US in measuring CCD. In classifying hip joint synovitis with US, the sensitivity of the method was 87% and specificity 42%, when the CCD criterion for synovitis was determined to be > or = 7 mm. If the cut-off point was raised to 9 mm, the sensitivity decreased to 61% while specificity increased to 94%. A difference in CCD of > or = 1 mm between the hips as an additional criterion for synovitis increased the number of false-positive findings. CONCLUSION Measurement of CCD with US proved to be a rather inaccurate method to point out synovitis in rheumatic patients when using MRI as a reference. The main reason for this result was the thickened capsule, which US could not differentiate from a thickened synovium.

Abstract
Genetic polymorphisms of the IL10 promoter region have been implicated in many autoimmune diseases, including seronegative spondyloarthropathies. We studied three SNPs (IL10-1087, -824, and -597) and two microsatellites (IL10R and IL10G) lying within the promoter region of IL10 for association with susceptibility to and clinical manifestations of ankylosing spondylitis (AS), a common form of spondyloarthritis. Four hundred and sixty-eight individuals from 182 Finnish families affected with AS were studied. No association between individual IL10 promoter region polymorphisms or marker haplotype was observed with susceptibility to AS, but weak association was noted between the IL10-597 and -824 SNPs and age of disease onset (P=0.01 for each SNP). The IL10.G4 allele was associated with BASFI (corrected for disease duration) (P=0.03). We conclude that IL10 promoter polymorphisms have no significant effect on susceptibility to AS, but may play a minor role in determining age of disease onset and disease severity.

Abstract
OBJECTIVE To establish the incidence of clinically important inflammatory cervical spine abnormalities in radiographs of patients with psoriatic arthritis (PsA). METHODS Patients were selected from a rheumatological outpatient clinic and one ward of the Rheumatism Foundation Hospital, Heinola, Finland, by examining 160 consecutive PsA cases. A total of 65 patients (38 women, 27 men) with PsA were identified who had cervical spine radiographs available. These were evaluated for inflammatory changes, and patient records studied for disease characteristics, laboratory and clinical findings. RESULTS In 12 cases (18%) inflammatory cervical spine changes were seen in the cervical spine radiographs. The most frequently detected was apophysial joint ankylosis, seen in seven patients (11%). Anterior atlantoaxial subluxation (aAAS) was seen in five (8%) and atlantoaxial impaction in three (5%). In 20 of the 40 patients who had the rotational range of neck motion measured the measurement was < or =45 degrees either to the left or the right side. CONCLUSION Inflammatory cervical spine changes were not commonly seen in radiographs of patients with PsA. Apophysial joint ankylosis and aAAS were detected most often. PsA may decrease the rotational range of neck motion significantly.

Abstract
The aim of this radiographic study was to ascertain the extent of inflammatory cervical spine disorders in patients with rheumatoid arthritis (RA) complicated by secondary amyloidosis (SA). The study involved 147 patients with RA and SA, whose cervical spine radiographs were available. They were treated at the Rheumatism Foundation Hospital, Heinola, during the period 1989-2000 and had had RA for a mean of 24 years. The inflammatory abnormalities of the cervical spine were studied from radiographs taken at or after the diagnosis of SA during flexion and extension. One-hundred and eleven (76%) patients had subluxations, impaction or apophyseal joint ankylosis. Atlantoaxial impaction (AAI) was seen in 76 (52%) patients and anterior atlantoaxial subluxation (AAS) in 59 (40%). Apophyseal joint ankylosis was the third most frequent finding, seen in 34 (23%) cases. A combination of AAI and apophyseal joint ankylosis was noted in 26 (18%) patients. Eight (5%) patients had undergone surgery on the cervical spine. In conclusion, inflammatory and destructive changes are frequent in the cervical spine of patients with RA and SA. Characteristic changes are AAI and AAS. RA patients with SA have more severe disease than those in epidemiological studies when cervical spine disorders are concerned.

Abstract
The objective of the study was to determine the long-term functional outcome of chronic spondylarthropathy (SpA) when measured by various functional indices. This information is important in the planning of long-term intervention studies and selection of the best follow-up methods. The study group consisted of 65 patients (21 women and 44 men) with SpA. Their mean age was 49 years and the mean age from diagnosis was 12 years. They completed several questionnaires (developed for the evaluation of functional capacity or the state of health of patients with SpA) at the beginning of the study and 3 years later. The questionnaires were: the Bath Ankylosing Spondylitis Functional Index (BASFI), the Dougados Functional Index (DFI), the Health Assessment Questionnaire for Spondylarthropathies (HAQ-S), the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Patient Global Assessment (BAS-G) and Stiffness-VAS (on a visual analogue scale). We also asked the patients to inform us if something had occurred in their lives during the follow-up that might have affected their health. Most of the indices (BASFI, DFI, BASDAI, BAS-G and Stiffness-VAS, but not HAQ-S) showed a statistically significant reduction in the functional capacity or state of health of the patients during the follow-up. Many factors occurring during the 3-year period may have influenced the results of the indices. The natural course of the functional capacity of patients with SpA appears to be one of impairment, when evaluated using these indices. Our experience also showed that it is very difficult to separate any effect of a single treatment intervention (e.g. rehabilitation) in a long-term follow-up study, as so many interfering factors, e.g. life events and health-related factors, may affect the follow-up population over several years.

Abstract
OBJECTIVE To ascertain whether being a carrier of an autosomal recessive disease, aspartylglucosaminuria (AGU), predisposes to chronic arthritis, as does AGU disease. METHODS A group of 173 unrelated patients with rheumatoid arthritis (RA) but with no family members with AGU each gave a blood sample for AGUFin major mutation DNA analysis. A group of 131 AGU carriers who were parents of patients with AGU completed a questionnaire on joint symptoms and gave a blood sample for rheumatoid factor (RF) analysis. Eight RF positive parents with prolonged joint symptoms had a rheumatological evaluation. RESULTS Six patients (1/28) with RA were carriers of the AGUFin major mutation, whereas the carrier frequency among Finns in general is 1/50 to 1/85. Three AGU carriers had chronic arthritis (2.3%), and 17 (13%) were RF positive; the respective percentages among Finns in general are 1.4% and 5%. CONCLUSION As for AGU disease, carrier status may also predispose to chronic arthritis.

Abstract
OBJECTIVE To describe inflammatory cervical spine disorders in juvenile chronic arthritis (JCA) patients with arthritis mutilans (AM) hand deformity. METHODS The series consisted of 18 patients affected by AM hand deformity who fulfilled the European League of Associations for Rheumatology criteria for JCA. The patient records and the most recent cervical spine radiographs were evaluated for subluxations, atlantoaxial impaction (AAI) and apophyseal joint ankylosis. RESULTS Seventeen (94%) patients had subluxation, AAI or apophyseal joint ankylosis in the cervical spine. Apophyseal joint ankylosis was noted in 12 (67%) patients and AAI in 10 (56%). Anterior atlantoaxial subluxation was detected in five (28%) patients. CONCLUSION Almost all of the JCA patients with AM hand deformity evinced some inflammatory changes in the cervical spine. Apophyseal joint ankylosis, AAI and multiplicity of changes in cervical spine may be considered characteristic in this subset of JCA patients. Patients with JCA and AM hand deformity tend to have severe changes also in the cervical spine.

Abstract
The purpose of this study was to detect the frequency of inflammatory cervical spine changes and characteristic features such as resorption in rheumatoid arthritis (RA) with arthritis mutilans (AM) hand deformity. The series included 23 patients with AM hand deformity who fulfilled the 1987 American Rheumatism Association criteria for RA. Cervical spine radiographs were evaluated for subluxations, atlantoaxial impaction (AAI), and apophyseal joint ankylosis. Assessment of the severity of inflammatory changes in the cervical spine was based on former radiographic criteria for operation. Twenty patients (87%) showed subluxations, AAI, or apophyseal joint ankylosis in the cervical spine. Anterior atlantoaxial subluxation (aAAS) was observed in nine (39%), AAI in 13 (57%), and apophyseal joint ankylosis in 12 (52%). Six (26%) had been operated on the cervical spine. Patients with AM hand deformity evinced frequent and severe inflammatory cervical spine changes often requiring operation. Resorptive change (AAI) in the upper cervical spine and ankylosis of apophyseal joints were the most characteristic abnormalities in these patients.

Abstract
OBJECTIVE To describe cervical spine abnormalities in a group of adult patients with refractory juvenile chronic arthritis (JCA) complicated by secondary amyloidosis (SA). METHODS The series consists of 49 patients who fulfilled the diagnostic criteria of the European League Against Rheumatism for JCA, here complicated by secondary amyloidosis (SA). We evaluated their clinical records and most recent cervical spine radiographs taken in adult age (> 18 years) at or after the diagnosis of SA. RESULTS Forty-two (86%) patients evinced inflammatory changes in the cervical spine. Apophyseal joint ankylosis was seen in 31 (63%) and atlantoaxial impaction (AAI) in 28 (57%) patients; anterior atlantoaxial subluxation (aAAS) was noted in 17 (35%) patients, and 19 (39%) had the combination of AAI and apophyseal joint ankylosis. The size of the 4th vertebral body was small or narrow in 14 (29%) patients with JCA onset at a median of 3 years of age (range 1-12). CONCLUSION Inflammatory cervical spine disorders are common and may be detected along the entire length of the cervical spine in patients with severe refractory JCA. The disorders tend to ankylose the apophyseal joints and destroy the atlantoaxial joints, resulting in aAAS or impaction. These changes will restrict rotatory and bending movements in the cervical spine. A peculiarly small or narrow cervical vertebral body was seen mainly in patients with early onset disease. The present findings shed light on the characteristics and course of the inflammatory changes in the cervical spine in patients with refractory JCA.
