Abstract
Summary
Objective: Review the history of health informatics in Africa as projected by the HELINA conferences, to draw inferences for the next phase.
Methods and materials: Summarising from the proceedings of HELINA 93, unpublished programmes and reports of later conferences, abstracts and presentations on the web sites of the most recent conferences, and personal recollections of all but one of the conferences. Analysing the e-health situation in Africa in 1993, 2007 and 2011 by mapping software applications presented in the respective conferences on a simplified model of potential spots for e-health use.
Results: The following phases were identified: Pre-phase from 1979; individual scientific papers. Phase 1, the 1993-1999 conferences; carried by the momentum of HELINA 93. Phase 2, interregnum; difficulty to find conference organisers. Phase 3, the 2007-2011 conferences; carried by the HELINA association as IMIA Africa Region. Currently most of the important spots for e-health use are being populated by appropriate software applications, mostly by collaborative open source projects. Phase 4 starting, characterised by the expansion of e-health practice on the continent, the HELINA association as a key organiser, and annual HELINA conferences becoming scientifically stronger and more visible.
Conclusions: Key issues in making health informatics blossom in Africa include local development capacity, community orientation, collaborative design, international collaboration, government support, champions and organised continent-wide collaboration.

Abstract
The evidence supporting the use of stabilisation splints in the treatment of temporomandibular disorders (TMD) is scarce and a need for well-controlled studies exists. The aim of this randomised, controlled trial study was to assess the efficacy of stabilisation splint treatment on TMD. The sample consisted of 80 consecutive referred patients who were randomly assigned to the splint group (n = 39) and the control group (n = 41). Subjects in the splint group were treated with a stabilisation splint, whereas subjects in the control group did not receive any treatment except counselling and instructions for masticatory muscle exercises which were given also to the subjects in the splint group. Outcomes were visual analogue scale (VAS) on facial pain intensity and clinical findings for TMD which were measured at baseline and after 1-month follow-up. The differences in change between the groups were analysed using regression models. Facial pain decreased and most of the clinical TMD findings resolved in both of the groups. The differences in changes in VAS or clinical TMD findings between the groups were not statistically significant. The findings of this study did not show that stabilisation splint treatment in combination with counselling and masticatory muscle exercises has additional benefit in relieving facial pain and increasing the mobility of the mandible than counselling and masticatory muscle exercises alone in a short time-interval.

Abstract
OBJECTIVES To evaluate the impact of antibodies to cyclic citrullinated peptide (ACPAs) on radiographic progression in patients with early rheumatoid arthritis (RA) initially treated either with a combination of 3 disease-modifying antirheumatic drugs (DMARDs) or with a single DMARD. METHODS This study included 129 patients with early active RA initially randomised to treatment either with a combination of methotrexate, sulfasalazine, hydroxychloroquine, and prednisolone (FIN-RACo) (n=69) or with a single DMARD (initially sulfalasalazine) with or without prednisolone (SINGLE) (n=60). After 2 years, the use of DMARDs and prednisolone became unrestricted. Radiographic progression in hands and feet was assessed at baseline and at 1, 2, 3, 4 and 5 years. ACPAs at baseline were determined with enzyme immunoassay. RESULTS ACPAs were positive in 92 (71%) patients. ACPA-positive vs. negative patients were more frequently rheumatoid factor (RF) positive (83% vs. 22%, p<0.001) and had an erosive disease (54% vs. 22%, p<0.001) at baseline. The presence of ACPA was associated with radiographic progression in FIN-RACo group even when the impact of RF was controlled; the radiographic progression was remarkably slower in ACPA-negative than in ACPA-positive cases (RF adjusted change over time between groups p=0.034). In the SINGLE group, the radiographic changes progressed parallel in ACPA-negative and positive patients. CONCLUSIONS Most ACPA-positive RA patients have joint erosions already at diagnosis. ACPA positivity in early RA was related to radiographic progression even in patients treated initially with the FIN-RACo regimen. The initial FIN-RACo therapy seems to slow down the progression of joint damage in ACPA-negative patients.

Abstract
OBJECTIVES To determine which disease-modifying anti-rheumatic drugs (DMARDs) are currently used by Finnish rheumatologists to treat early rheumatoid arthritis (RA). METHODS Information on sex, date of birth, and date of special medicine reimbursement decision for all new RA patients was collected from a nationwide register maintained by the Social Insurance Institution (SII) during the time period from 1 January 2000 to 31 December 2007. Patient cohorts were registered in 2-year time periods (2000-01, 2002-03, 2004-05, 2006-07) and DMARDs purchased by the patient cohorts during the first year after the date of reimbursement decision for RA were registered. The frequencies of early drug treatment strategies (combination of DMARDs, single DMARD, or no DMARDs) were evaluated. RESULTS A total of 14 878 (68.0% female, 62.6% rheumatoid factor (RF)-positive) patients were identified. Between 2000 and 2001 the most commonly used treatment strategy for early RA during the first 3 months was single DMARD treatment (56.1%) and the most commonly used DMARD during the first year was sulfasalazine (63.0%), while between 2006 and 2007 the respective treatments were combination DMARDs (55.3%) and methotrexate (69.0%). The change in treatment strategies as well as in DMARDs used was highly significant (p < 0.001 for linearity). At the end of the study period only 4.9% of the patients with early RA were not receiving DMARDs during the first 3 months. CONCLUSIONS Currently, combination therapy including methotrexate is the most commonly prescribed treatment strategy for early RA in Finland. In recent years, an increasing number of active drug treatments have been taken into practice.

Abstract
OBJECTIVE To evaluate the volumetric brain magnetic resonance imaging (MRI) findings in a population-based sample of systemic lupus erythematosus (SLE) patients and to detect a possible relationship between cerebral MRI abnormalities and specific neuropsychiatric (NP) manifestations. METHODS The study population consisted of patients with SLE (n = 43) in Pirkanmaa Health Care District, Finland and of a sex- and age-stratified reference group from the general population (n = 43). In addition to a clinical neurological investigation, all subjects received a detailed neuropsychological assessment and an MRI study. Volumetric measures of cerebral atrophy as well as T1- and T2-weighted lesions were obtained. SLE activity was assessed by the European Consensus Lupus Activity Measure (ECLAM) index, and accumulated NP abnormalities were measured by the Systemic Lupus International Collaborating Clinics (SLICC) damage index. A cumulative lifetime dose of glucocorticoids was determined from the patientrecords. RESULTS Compared with controls, SLE patients had increased volumes of both T1- and T2-weighted lesions (p = 0.019 and p<0.0001, respectively) and increased cerebral atrophy (p<0.001). All the measured MRI parameters were statistically significantly higher in NPSLE than in non-NPSLE patients. In SLE patients, cerebral atrophy was associated with cognitive dysfunction, epileptic seizures, and cerebrovascular disease; T1-weighted lesions were associated with epileptic seizures and T2-weighted lesions with cognitive dysfunction. All MRI parameters correlated significantly with the SLICC index but not with the ECLAM index. A positive correlation was found between a cumulative dose of glucocorticoids and cerebral atrophy in SLE patients. CONCLUSION MRI abnormalities, including brain atrophy and T1- and T2-weighted lesions, are significantly more common in patients with SLE than in the general population and they are related to specific NP manifestations. Our findings also provide support for the organic aetiology of cognitive dysfunction in SLE.

Abstract
OBJECTIVE To explore the cost of the statutory inpatient rehabilitation system in Finland and its impact on the functional and work capacity of patients with early rheumatoid arthritis (RA). METHODS In the Finnish Rheumatoid Arthritis Combination-Therapy trial (FIN-RACo), 195 patients with recent-onset RA, 162 of them available for the work force, were randomly assigned to two different drug treatment strategies for 2 years. Otherwise, the patients received routine multidisciplinary care and, if their functional or work capacity was endangered, were referred to inpatient rehabilitation. After a 5-year follow-up, data on rehabilitation, sick leave, and RA-related disability pensions were obtained from official registers. RESULTS Of the 162 patients, 49 (30%) underwent inpatient rehabilitation at an average cost of EURO5400. The rehabilitated patients more often worked in white-collar jobs and had more pain and a worse Health Assessment Questionnaire (HAQ) score (1.0 vs. 0.78; p = 0.01) at baseline. Their HAQ scores remained higher throughout follow-up (p<0.001); no change appeared over inpatient periods [mean 0.01; 95% confidence interval (CI) -0.13 to 0.16]. No independent impact of rehabilitation on the HAQ score emerged in an adjusted generalized estimating equations (GEE) model (p = 0.55). Nor did any improvement in work capacity appear: average lost productivity (human capital approach) per patient-year was EURO10 155 (95% CI 6994-14 196) before and EUR 12 839 (95% CI 8589-19 139) after the start of rehabilitation. CONCLUSION For patients with recent-onset RA, the Finnish statutory inpatient rehabilitation system had no positive impact on either functional or work capacity during the first few years, despite its considerable cost.

Abstract
OBJECTIVE To assess the mortality and causes of death in a cross-sectional population-based study of 1042 patients with rheumatoid arthritis (RA). METHODS In 1988, 604 RA patients [470 females (F), 134 males (M)] and 457 age- and sex-matched controls (352 F, 105 M) were examined prospectively (participants) and 438 (183 F, 81 M) non-participant RA patients retrospectively. In 1999, vital status and causes of death were determined. Mortality in the total RA population was compared to that in the general population, and that among participant RA patients to their matched controls. RESULTS A total of 384 (37%) RA patients and 71 (16%) controls died. RA patients had increased mortality compared to the general population (standardized mortality ratios SMR 2.64) or controls (1.71). This was observed in both sexes. Over 40% of deaths in all groups were due to cardiovascular diseases. RA patients were at increased risk of dying of urogenital, gastrointestinal, respiratory and cardiovascular diseases, infections, and cancers when compared to the general population or controls. CONCLUSIONS Our results show that a cross-sectional cohort of RA patients had an increased risk of death from various causes.

Abstract
OBJECTIVE To explore the combination of data on functioning and work load for early identification of patients at risk for diminished work productivity in rheumatoid arthritis (RA). PATIENTS AND METHODS In the FIN-RACo trial, 162 patients with recent onset RA and available for the workforce were treated with either a combination of disease-modifying antirheumatic drugs (DMARDs) or a single DMARD for 2 years. Otherwise, they received routine care and were followed up for 5 years. Data on their individual income and lost work days came from official registers. Loss of productivity was computed by the human capital approach. Self-reported data on physical work demand (Finnish Institute for Occupational Health Questionnaire) at baseline and on functioning (HAQ) at 6 months were linked according to the International Classification of Functioning, Disability and Health. RESULTS Data on 112 patients were analyzable at 6 months; 35 (31%) of them had diminished capacity in functions required at paid work. Any mismatch between perceived abilities and requirements predicted future (7 through 60 months) loss of productivity - on average Euro 14,040 (95% confidence interval (CI): 9,143-20,511) per year in patients with the mismatch compared to Euro 3,043 (1,623-5,534) in those without any mismatch - and was associated with RA-related permanent work disability (hazard ratio: 11.6; 95%CI: 4.0-33.4). CONCLUSION Linking together self-reported data about functioning and work load helps in early identification of the RA patients at risk for loss of working days.

Abstract
We studied 71 patients with acute Yersinia infection for the occurrence of pathologic urinary and renal findings. Transient proteinuria and/or microhematuria was found in 17 patients (24%) and slightly elevated serum creatinine in seven patients (10%). Renal biopsy was done in two patients and revealed mild mesangial glomerulonephritis in both cases. One of these patients had IgA glomerulonephritis and Reiter's syndrome. Pyuria occurred in 16 patients (23%) and was frequently associated with Reiter's syndrome. Seventy-three patients with acute intrinsic renal failure were studied for the occurrence of acute Yersinia infection by determining Yersinia antibodies by ELISA. One out of 13 patients with acute glomerulonephritis but none of 60 patients with acute tubulointerstitial renal disease had acute Yersinia infection. Acute Yersinia infection seems to be rarely an etiologic factor in acute intrinsic renal failure. Our results indicate that transient proteinuria, microhematuria, pyuria or impaired renal function are frequent findings in patients with acute Yersinia infections. However, glomerulonephritis seems to be a rather infrequent and mild complication of acute Yersinia infection.

Abstract
OBJECTIVES Interoperability of applications in health care is faced with various needs by patients, health professionals, organizations and policy makers. A combination of existing and new applications is a necessity. Hospitals are in a position to drive many integration solutions, but need approaches which combine local, regional and national requirements and initiatives with open standards to support flexible processes and applications on a local hospital level. METHODS We discuss systems architecture of hospitals in relation to various processes and applications, and highlight current challenges and prospects using a service-oriented architecture approach. We also illustrate these aspects with examples from Finnish hospitals. RESULTS A set of main services and elements of service-oriented architectures for health care facilities are identified, with medium-term focus which acknowledges existing systems as a core part of service-oriented solutions. The services and elements are grouped according to functional and interoperability cohesion. CONCLUSIONS A transition towards service-oriented architecture in health care must acknowledge existing health information systems and promote the specification of central processes and software services locally and across organizations. Software industry best practices such as SOA must be combined with health care knowledge to respond to central challenges such as continuous change in health care. A service-oriented approach cannot entirely rely on common standards and frameworks but it must be locally adapted and complemented.

Abstract
OBJECTIVE To study interleukin (IL)-1beta levels in recent onset RA patients treated either with combination DMARD therapy (sulfasalazine, methotrexate, hydroxychloroquine) or a single DMARD therapy. METHODS Serum IL-1beta levels were measured before the treatment and 6 months after the institution of either single or combination DMARD therapy using a high sensitivity ELISA method. Radiographic evaluation of the hands and feet was performed at 0 and 24 months. RESULTS Significant correlations (r = 0.28, 95% CI 0.10-0.45) were found between IL-1beta levels measured at 0 and 6 months. The IL-1beta levels at 0 months correlated significantly (r = 0.23, 95% CI 0.03-0.4, p= 0.021) with the baseline number of eroded joints at 0 months but not with radiographic joint damage at 24 months. The baseline level of IL-1beta was a better indicator for the presence of eroded joints than the baseline level of serum CRP. No significant changes in IL-1beta levels were observed during the first 6 months of anti-rheumatic treatment in either group. No statistically significant difference between IL-1beta levels in the patients with or without the shared epitope could be observed. CONCLUSIONS The serum IL-1beta level is significantly associated with the presence of erosions at the onset of RA but its predictive value is attenuated or lost when single or combination DMARD medication is instituted. Measuring IL-1beta at the time of diagnosis in a single patient cannot be used to estimate the erosive nature of the disease or the prognosis.

Abstract
OBJECTIVES Cytokines play a key pathogenic role in rheumatoid arthritis (RA). Several cytokines signal through the JAK-STAT pathway, which is negatively regulated by the suppressors of cytokine signalling (SOCS) proteins. Since SOCS protein levels can profoundly modulate cellular responses to cytokines, we have investigated their expression in chronic RA. METHODS The levels of SOCS1-3 and CIS1 mRNA in peripheral blood (PB) and synovial fluid (SF) mononuclear cells (MCs), purified T cells and monocytes from RA patients and healthy volunteers were studied using quantitative reverse transcriptase polymerase chain reaction (RT-PCR). SOCS mRNA and protein expression in synovial tissues were examined by RT-PCR and immunohistochemistry. RESULTS The levels of SOCS1 and SOCS3 were significantly increased in PBMCs from RA patients when compared with healthy volunteers. These differences were mainly due to up-regulation of SOCS1 in PB T cells and of SOCS3 in PB monocytes. In addition, SOCS2 was up-regulated in PB T cells. Interestingly, SF T cells expressed lower and SF macrophages higher levels of SOCS molecules than their PB counterparts. Similarly, while a significant portion of macrophages in synovial tissues expressed SOCS1 and SOCS3 proteins, the majority of T cells remained SOCS negative. Finally, SOCS1 was up-regulated in the synovial membranes from patients with RA when compared with osteoarthritis. CONCLUSIONS SOCS expression levels are profoundly altered in RA, and the profile of SOCS expression is dependent on both the cell type as well as the cellular compartment.

Abstract
Indoleamine 2,3-dioxygenase (IDO) is a tryptophan-degrading enzyme which suppresses T lymphocyte activity. IDO activity can be determined by relating kynurenine, the main metabolite of tryptophan, to tryptophan (kyn/trp). We have demonstrated recently that systemic lupus erythematosus (SLE) is activated during the sunny season as measured by the European Consensus Lupus Activity Measurement Index (ECLAM) activity score. Our aim here was to establish whether IDO-dependent mechanisms are involved in the activation process of SLE. Kyn/trp was measured by reverse-phase high-performance liquid chromatography (HPLC) in 33 (30 female, three male) SLE patients in winter, spring and summer and in 309 healthy control subjects. At the same time-points the SLE patients were examined by a rheumatologist and a dermatologist and the activity of SLE assessed by the ECLAM score. IDO activity was higher in SLE patients than in healthy subjects. There was no seasonal variation in IDO activity in SLE patients and it did not correlate with the ECLAM activity score in winter. However, there was a significant correlation between IDO activity and the ECLAM score both in spring and in summer. High IDO activity in winter predicted subsequent activation of SLE in spring and summer. Our results indicate that IDO-dependent immunosuppressive mechanisms are activated in SLE patients. Exposure to sunlight or another factor causing seasonal variation in SLE activity leads to insufficiency of this suppression in a subgroup of patients, causing activation of SLE. High IDO activity in winter predicts activation of SLE in the sunny season.

Prognosis of clinical renal disease and incidence of new renal findings in patients with rheumatoid arthritis: follow-up of a population-based study. Clin Rheumatol 2007; 26:2089-2095. [PMID: 17492249 DOI: 10.1007/s10067-007-0625-y] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2007] [Revised: 04/09/2007] [Accepted: 04/11/2007] [Indexed: 11/26/2022]
Abstract
The objective of this study was to assess the long-term prognosis of nephropathy findings and the incidence of new abnormal clinical renal findings in patients with rheumatoid arthritis (RA). The original population-based cross-sectional study of 604 RA patients was carried out in 1988, 103 nephropathy patients being found. Controls matched for age, sex, and duration of RA were selected from among RA patients with normal renal function and urinalysis in 1988. In 2003, a follow-up study was made of the 103 nephropathy patients and 102 controls, and the median follow-up time was 13 years. In the original nephropathy group, serum creatinine exceeded 200 mumol/l in 8% of the original isolated hematuria patients, in 30% of the isolated proteinuria patients, in 57% of the combined hematuria and proteinuria patients, but in none of the isolated chronic renal failure (CRF) patients (p = 0.001 for the difference). Probable or definitive renal amyloidosis was diagnosed in 19% of the nephropathy patients. Dialysis therapy was given to 10 out of the 103 nephropathy patients, nine of them belonging to the original isolated proteinuria or combined hematuria and proteinuria groups. There were six renal deaths among the nephropathy patients, and none in the controls. In the control group, new abnormal renal findings, in most cases mild, were detected in 28%. Serum creatinine exceeded 200 mumol/l in 4% of the controls, and dialysis therapy was given to 2% of the controls. Probable or definitive renal amyloidosis was diagnosed in 4% of this group. With regards to the development or progression of chronic renal failure, the long-term clinical prognosis of isolated hematuria and isolated CRF was found to be favorable. Proteinuria alone or combined with hematuria or CRF was related to evidently poorer prognosis.

Abstract
OBJECTIVE To study the associations of tumor necrosis factor (TNF) a, b and c microsatellite markers with 1) the clinical disease activity and 2) the induction of remissions in patients with early rheumatoid arthritis (RA) treated with two treatment strategies. METHODS In the FIN-RACo (FINnish Rheumatoid Arthritis Combination therapy) trial of two years, 195 patients with recent-onset RA were randomly assigned to receive either a combination (COMBI) (sulphasalazine, methotrexate, hydroxychloroquine, and prednisolone) or a single (SINGLE) (initially sulphasalazine with or without prednisolone) disease modifying antirheumatic drug (DMARD) therapy. TNF a, b and c microsatellite and HLA-DRB1 typings were carried out in 165 (79 COMBI; 86 SINGLE) study completers. RESULTS At baseline the 28 joint disease activity scores (DAS28) of the patients positive for TNFa2, a13 or b1 microsatellite markers were significantly higher than in the other patients. In the SINGLE patients the DAS28 improved comparably in patients with (n = 31) or without (n = 53) the TNFb1 marker (NS), while the DAS28 of the TNFb1-positive COMBI patients (n = 22) improved significantly more than that of the TNFb1-negative cases (n = 57) (p = 0.014). Respective 31.8% (7/22) and 28.1% (16/57) of the COMBI patients with or without TNFb1 allele achieved remission at one year. The corresponding figure in SINGLE patients were 0% (0/31) and 20.8% (11/53) (p = 0.006). At two years the remission frequencies in the TNFb1+/TNFb1- patients in the COMBI and SINGLE were 50.0%/38.6% and 9.7%/22.6%, respectively. CONCLUSION Early TNFb1+ RA patients have more active disease but respond more favourably to COMBI treatment than the patients without this microsatellite allele. The finding may be of clinical relevance for the choice of DMARDs in early RA.

Abstract
OBJECTIVE To explore the monetary value of rheumatoid arthritis related loss of productivity in patients with early active disease. METHODS In a prospective cohort substudy of the FIN-RACo Trial, 162 patients with recent onset rheumatoid arthritis, aged 18 to 65 years and available to the workforce, were followed up for five years. Loss of work productivity in euros 2002 was estimated by data on absence for sickness and on income (human capital approach) from official databases. Treatment responses were evaluated by area under the curve (AUC) of the ACR-N measure and by increase in number of erosions in radiographs of hands and feet. The health assessment questionnaire (HAQ) at six months was linked to the International Classification of Functioning, Disability and Health (ICF). RESULTS In all, 120 (75%) patients, women more often (82%) than men (61%) (p=0.002), lost work days. The mean lost productivity per patient-year was euro7217 (95% confidence interval (CI), 5561 to 9148): for women, euro6477 (4858 to 8536) and for men, euro8443 (5389 to 12,898). There was an inverse correlation with improvement: euro1101 (323 to 2156) and euro14 952 (10,662 to 19,852) for the highest and lowest quartiles of AUC of ARC-N, respectively. Lost productivity was associated with increase in the number of erosions and with disability in "changing and maintaining body position" subcategory of the ICF. CONCLUSIONS Despite remission targeted treatment with disease modifying antirheumatic drugs, early rheumatoid arthritis results in substantial loss of productivity. A good improvement in the disease reduces the loss markedly.

Abstract
The aim of this study was to determine whether the +896 A-->G substitution of the Toll-like receptor 4 (TLR4) gene, causing the Asp299-->Gly change in the extracellular domain of TLR4, influences treatment response in recent-onset rheumatoid arthritis. 169 patients with rheumatoid arthritis were genotyped from the Finnish Rheumatoid Arthritis Combination Therapy trial, in which they were treated either with only one disease-modifying antirheumatic drug (DMARD) with or without prednisolone (single group), or with three DMARDs and prednisolone (combination group). Patients homozygotic for the wild-type +896A allele were compared with those having the polymorphic G allele in terms of early clinical response (at 6 months) by the 28-joint Disease Activity Score (DAS28). 1 of 20 (5%; (95% (confidence interval (CI) 1 to 5)) patients of the single group with TLR4 +896AG or GG and 29 of 67 (43%; (95% CI 31 to 56)) patients with AA were in remission (p = 0.001). DAS28 of the single group with TLR4 +896AG or GG was higher than with AA (p = 0.019). In the combination group, remission rates and DAS28 values were comparable between the genotypes. The polymorphic TLR4 +896G allele may impair treatment response to single DMARD treatment in recent-onset rheumatoid arthritis.

Abstract
To assess the performance of infliximab in a clinical setting, 364 rheumatoid arthritis (RA) patients from the National Register of Biological Treatment in Finland (ROB-FIN) were analysed. Corticosteroid usage and dose diminished (p<0.05 and 0.001, respectively) in patients on infliximab, of whom 51% also used one, 28% two and 16% three other concomitant DMARDs. A 34% of the RA patients used methotrexate+/-corticosteroids without any other DMARD. Methotrexate was most frequently used with sulphasalazine and/or hydroxychloroquine. Non-methotrexate patients most frequently used leflunomide or azathioprine combined with corticosteroids. The clinical effect of these combinations was similar to that of infliximab with methotrexate alone. The results indicate that infliximab can be used together with other DMARDs than methotrexate alone, quite according to the philosophy of the combination drug therapy, as the effectiveness is as good as or even slightly better than that of methotrexate and infliximab.

Abstract
OBJECTIVE To study the value of baseline serum levels of circulating soluble interleukin-2 receptor (sIL-2R) and soluble E-selectin as predictors of early remission in patients with recent-onset rheumatoid arthritis (RA) receiving a single disease-modifying anti-rheumatic drug (DMARD) (SINGLE) or therapy with a combination of DMARDs (COMBI). METHODS Baseline (n = 157) serum samples originate from the FIN-RACo (FINnish Rheumatoid Arthritis Combination therapy) trial, in which 195 patients with early and clinically active RA were randomly assigned to receive either SINGLE (initially sulfasalazine) with or without prednisolone, or COMBI therapy (sulfasalazine, methotrexate, hydroxychloroquine, and prednisolone). Of the samples, 76 were from SINGLE patients and 81 from COMBI patients. sIL-2R was measured by automated immunoassay analyzer and sE-selectin by enzyme-linked immunosorbent assay. RESULTS At six months, 7 (9% [95% CI: 4 to 18]) SINGLE and 19 (23% [95% CI: 15 to 34]) COMBI patients were in remission. In multivariate logistic regression analysis, sIL-2R <442 U/ml and COMBI therapy were the only predictors of remission. The area under receiver operating characteristic curve for sIL-2R level was 0.86 (95% CI: 0.62 to 0.95) in SINGLE and 0.57 (95% CI: 0.42 to 0.71) in COMBI (p = 0.006). In SINGLE, the optimal cut offpoint was 442 U/ml, lower levels predicting remission with sensitivity of 83% (95% CI: 73% to 91%) and specificity of 86% (95% CI: 42% to 100%). Likelihood ratio for positive test was 5.9 (95% CI: 1.6 to 32.8). In multivariate logistic regression analysis, sIL-2R <442 U/ml and COMBI therapy were the only predictors of remission. CONCLUSION Low baseline serum sIL-2R level predicts early remission of patients with active early RA treated with a single DMARD.

Abstract
OBJECTIVE To explore baseline risk factors for productivity loss and work disability over 5 years in patients with early, active RA. PATIENTS AND METHODS In the FIN-RACo trial, 195 patients with recent onset RA were randomised to receive either a combination of DMARDs with prednisolone or a single DMARD for 2 years. At baseline, 162 patients were working or available for work. After 5 years' follow up, data on sick leave and retirement were obtained from social insurance registers or case records. The cumulative duration of sick leaves and RA related disability pensions was counted for each patient. To analyse predictors of productivity loss, the patients were divided into four groups according to duration of work disability per patient year. RESULTS Patient's and physician's global assessment of RA severity > or =50 and HAQ score > or =1.0 were risk factors for extension of productivity loss (OR (95% (CI) 1.77 (1.00 to 3.16), 1.85 (1.03 to 3.32), and 1.78 (1.01 to 3.14), respectively). Additional risk factors were low education level (2.40 (1.18 to 4.88)) and older age (1.03 (1.00 to 1.06)); combination treatment was a protective factor (0.59 (0.35 to 0.99)). CONCLUSION At baseline, the risk of future productivity loss is best predicted by education level, age, global assessments of RA severity, and HAQ score.

Abstract
OBJECTIVE Both coeliac disease (CD) and Sjogren's syndrome (SS) have an autoimmune background and increased risk of oral mucosal and dental abnormalities. Individuals suffering concomitantly from CD and SS could even be at a higher risk. STUDY DESIGN Oral mucosal and dental abnormalities were examined in 20 patients with CD + SS (mean age 61 years) and compared with age- and sex-matched controls with either CD or SS. RESULTS Oral mucosal changes were most common in SS (80%), followed by CD + SS (65%) and CD (40%). Coeliac-type dental enamel defects were found in 89% in CD + SS and in 88% in CD compared with only 25% in SS (P < 0.001). The median number of teeth was six in the CD + SS, 24 in the CD and 22 in the SS group. The DMF index was higher (P < 0.005) in the CD + SS than in the CD group. CD + SS was characterized by higher salivary flow rate (P < 0.001) and lower inflammatory focus score in the salivary glands (P < 0.01) than SS. CONCLUSIONS The co-occurrence of CD and SS should be recognized because of its effects on dental and oral mucosal health. A lower salivary gland inflammatory focus score and higher salivary flow rate in CD + SS than in SS suggests that a gluten-free diet treatment may alleviate autoimmune inflammation.

Abstract
OBJECTIVES To elucidate the contribution of HLA-DR-DQ haplotypes and their genotypic combinations to susceptibility to rheumatoid arthritis, and to evaluate the various models for HLA associated risk for the disease in a series of Finnish patients. METHODS 322 Finnish patients with rheumatoid arthritis were typed for common north European HLA-DR-DQ haplotypes and compared with a series of 1244 artificial family based control haplotypes. RESULTS The association of the so called shared epitope (SE) haplotypes (DRB1*0401, *0404, *0408, and *01) with rheumatoid arthritis was confirmed. The DRB1*0401 haplotypes carried a far stronger risk for the disease than the (DRB1*01/10)-(DQA1*01)-DQB1*0501 haplotypes. Seven protective HLA haplotypes--(DRB1*15)-(DQA1*01)-DQB1*0602; (DRB1*08)-(DQA1*04)-DQB1*04; (DRB1*11/12)-DQA1*05-DQB1*0301; (DRB1*1301)-(DQA1*01)-DQB1*0603; (DRB1*1302)-(DQA1*01)-DQB1*0604; (DRB1*07)-DQA1*0201-DQB1*0303; and (DRB1*16)- (DQA1*01)-DQB1*0502--were identified. In accordance with the reshaped shared epitope hypothesis, all the protective DRB1 alleles in these haplotypes share either isoleucine at position 67 or aspartic acid at position 70 in their third hypervariable region motif. However, differences in the disease risk of haplotypes carrying the same DR but different DQ alleles were also found: (DRB1*07)-DQA1*0201-DQB1*0303 was protective, while (DRB1*07)-DQA1*0201-DQB1*02 was neutral. The same haplotypes carried different risks for rheumatoid arthritis depending on their combination in genotypes. CONCLUSIONS When assessing the influence of HLA genes on the susceptibility to rheumatoid arthritis, not only should the HLA-DR or -DQ alleles or haplotypes be unravelled but also the genotype. The effect of HLA class II region genes is more complicated than any of the existing hypotheses can explain.

Abstract
OBJECTIVES To study the role of different seasons in the disease activity of patients with systemic lupus erythematosus (SLE). Additionally, to evaluate whether the outdoor behaviour during the summer or a photoprovocation test affects disease activity. METHODS 33 patients with SLE were examined by a rheumatologist and a dermatologist at a university hospital in winter, spring, and summer. The activity of SLE was assessed by the ECLAM index. Their outdoor behaviour was recorded by a questionnaire during the summer. In the winter, 12 patients were photoprovoked by ultraviolet A and B radiation on a small skin area. RESULTS The ECLAM scores were higher in spring and tended to be higher in summer than in winter (p = 0.006 and p = 0.051). This finding, as well as the outdoor behaviour, were independent of the patients' own impression of their photosensitivity. Overall, the sun protection actions were inadequate. The photoprovocation had no statistical effect on disease activity, but one patient had a violent exacerbation of SLE manifestations shortly after the photoprovocation. CONCLUSIONS In the northern climate SLE may be activated during the sunny season. Therefore, more effort should be focused on sun protection of patients with SLE.

Abstract
BACKGROUND In a previous study pulmonary hyperinflation was observed frequently in patients with primary Sjogren's syndrome (pSS) and elevated serum beta-2 microglobulin (beta2m) concentrations were associated with hyperinflation. OBJECTIVE To evaluate the significance of baseline serum beta2m concentration and to identify other possible risk factors for pulmonary involvement in long-term follow-up of patients with pSS. METHODS Nineteen pSS patients whose pulmonary function tests (PFTs) had been previously studied were reexamined after a median follow-up of 10 years. Pulmonary symptoms were recorded, chest radiograph, and high-resolution computed tomography (HRCT) were evaluated and methacholine provocation and PFTs including flow-volume spirometry, body plethysmography, and diffusing capacity performed. RESULTS Baseline serum beta2m concentrations correlated inversely with follow-up total lung capacity (TLC), vital capacity (VC), and diffusing capacity (DL), and positively with residual volume (RV), all expressed as percentage of predicted values. Diminished airways resistance (Raw) and, correspondingly, elevated specific conductance (SGaw) were frequent findings in pSS patients at follow-up, indirectly implying stiffness of the lungs and a restrictive decrease in lung volumes. Baseline serum protein concentration was higher and IgG concentration tended to be higher in pSS patients who at follow-up had elevated SGaw compared with others. Interstitial changes in HRCT were found more frequently in patients with elevated SGaw than in those without. CONCLUSION Our results suggest that subtle restrictive changes in pulmonary function are more prone to develop in the long term in pSS patients with elevated serum beta2m concentration and other signs of immunological activity at baseline.

Abstract
AIMS AND METHODS Mortality among RA patients and controls was analyzed with special attention to renal disease in population-based material (originally screened in 1988) of 604 patients with RA (470 females, 134 males) and 457 age- and sex-matched controls (352 females, 105 males). In the original RA population, isolated hematuria (HU) was observed in 54, isolated proteinuria (PU) in 27, combined hematuria and proteinuria (HUPU) in 7, chronic renal failure (CRFtot) in 36 and isolated chronic renal failure without HU or PU (CRFisol) in 15 patients. Among the controls, HU was observed in 39, PU in 11, CRFtot in 32 and CRFisol in 16 subjects. HUPU was not observed in any of the controls. Microalbuminuria (20-200 microg/min) was observed in 34 RA patients and in 27 controls. Histologically confirmed amyloidosis was found in 13 RA patients and mesangial glomerulonephritis (MesGN) in 17 patients. The mortality was evaluated in 1999 from data of the Statistical Office of Finland. Statistical analysis was performed by Cox regression analysis. RESULTS Mortality was significantly increased in the RA population as compared to controls: hazard ratio (HR) 1.78 (95% CI 1.34-2.31) for all RA patients; HR 2.12 (1.52-2.94) for females; HR 1.15 (0.75-1.77) for males. In the RA material, increased mortality was detected in patients with HUPU (HR 4.45; 1.54-12.84), PU (HR 3.54; 1.88-6.65), CRFtot (HR 3.74; 2.55-5.56) or microalbuminuria (HR 2.77; 1.64-4.69) when compared to those with normal clinical renal findings, whereas HU (HR 1.49; 0.88-2.52), CRFisol (HR 1.71; 0.82-3.54), bacteriuria (HR 0.96; 0.35-2.59) or pyuria (HR 0.65; 0.09-4.65) did not predict mortality. Renal amyloidosis was associated with an over twofold mortality rate (HR 2.31; 1.03-5.15), whereas mortality was within expected limits in RA patients with MesGN (HR 1.61; 0.49-5.24). CONCLUSION Our results show that nephropathy presenting with combined hematuria and proteinuria, proteinuria, microalbuminuria or histologically confirmed amyloidosis is associated with increased mortality in RA patients, whereas mortality is within expected limits in those with isolated hematuria or mesangial glomerulonephritis.

Abstract
OBJECTIVE To study the effects of Lactobacillus rhamnosus GG (LGG) on rheumatoid arthritis (RA). METHODS Twenty-one RA patients were randomised to receive 2 capsules of LGG or a placebo twice daily in double-blind fashion for 12 months. Arthritis activity was evaluated by clinical examination, HAQ index, and laboratory tests (e.g. ESR, CRP, pro- and anti-inflammatory cytokines). RESULTS There were no statistical differences in the clinical parameters, biochemical variables and HAQ index between the study groups over the intervention period. The mean number of tender and swollen joints decreased from 8.3 to 4.6 in the Lactobacillus group and from 5.5 to 4.8 in the placebo group (p = 0.41). According to the global assessment the RA activity was reduced in 71% (LGG group) vs. 30% (controls) (p = 0.15). Serum IL-1 beta increased slightly in the LGG group (p = 0.07), but no differences were seen in IL-6, TNF-alpha, MPO, IL-10 or 1L-12. CONCLUSIONS Although there were no statistical significant differences in the activity of RA, more subjects in the LGG group reported subjective well being. More studies on the effects of probiotic bacteria in RA are needed.

Abstract
BACKGROUND The value of antibiotics in the treatment of reactive arthritis (ReA) is still controversial. OBJECTIVES To analyse the long term outcome of patients with ReA, treated with a three month course of ciprofloxacin or placebo. METHODS Patients who had had ReA and had participated in a double blind, placebo controlled trial on the effectiveness of ciprofloxacin 4-7 years earlier were invited to a clinical examination. Of the 71 patients who were included in the original study, 53 agreed to visit the clinic for an examination. Twenty six of 53 patients had originally received ciprofloxacin and 27 had belonged to the placebo group. Of these, 20 in the ciprofloxacin and 25 in the placebo group were HLA-B27 positive. RESULTS 11/27 (41%) patients in the original placebo group had now developed chronic rheumatic disease, as compared with only 2/26 (8%) patients originally treated with ciprofloxacin (p=0.006). Two patients who originally had received placebo, none in the ciprofloxacin group had developed ankylosing spondylitis, and three patients in the original placebo group, none in the ciprofloxacin group had recurrent anterior uveitis. The same tendency was seen when several different measures were analysed. Of the patients with chronic spondyloarthropathy, 10 in the placebo and none in the ciprofloxacin group were HLA-B27 positive. CONCLUSION Analysis 4-7 years after the initial ReA suggests that a three month course of antibiotics in the acute phase may have a beneficial effect on the long term prognosis.
