The relationship between disease activity, quality of life, and personality types in rheumatoid arthritis and ankylosing spondylitis patients.

We hypothesized that clinical outcomes might be influenced by personality type (A, B, C, D) in rheumatoid arthritis (RA) and ankylosing spondylitis (AS). One hundred ninety-four patients (104 with RA, 90 with AS) participated in a questionnaire study. We evaluated health-related quality of life (HRQoL) using the Medical Outcome Study Short-Form 36 (SF-36), personality type A/B with the Jenkins Activity Survey, type C with the State-Trait Anger Expression Inventory Anger-in Scale, type D with the Type D Personality Scale, and disease activity with Disease Activity Score with 28 joints for RA and Bath Ankylosing Spondylitis Disease Activity Index for AS. We used Pearson's correlation coefficient, independent samples t tests, and multivariate analyses of variance. In the RA group, type D personality was significantly correlated with 7/12 SF-36 components. AS patients with type D personality had deficits in all SF-36 subscales. Type D was related with higher disease activity in RA and AS. Both RA and AS type C patients had more active disease forms and negatively affected HRQoL subscales. In the RA group, type A personality did not correlate with HRQoL, but it positively influenced pain visual analog scale scores. In AS patients, type A personality was linked with higher HRQoL and with less active disease. Type C and type D personality types were correlated with decreased HRQoL and higher disease activity in RA and AS patients. Type A personality was associated with less active disease and higher HRQoL in AS patients and with less pain in RA patients.

Socio-economical factors that influence the perception of quality of life in patients with osteoporosis.

The appearance of osteoporosis in elders and the growth of the frequency which it is diagnosed with as we approach patients who are older and older, makes this health problem very important in the societies in which a high number of persons reach old age. These societies, usually belonging to economically advanced jurisdictions, are the first interested in the way health expenses can balance the benefits of the quality of life acquired in these groups of population. The evaluation of the quality of life has become a very important process, which still raises methodological problems to the researchers. The aim of this study was to analyze to what extent the factors involved in defining the quality of life by the patients modified according to the existence of osteoporosis as a defined but also as a perceived disease, as far as it is considered a serious or less serious affection by each patient. 210 female patients participated in the study. The statistical analysis was done by using SPSS 22.0 (IBM Corp. - U.S.A.). p < 0,05 was used as a limit for the statistical significance. Descriptive and analytical analyses were made by following Pearson correlation index in cases of normal distributions, the comparison between groups was made by using t-Student test, respectively chi square test in the cases which required its use. The current study highlights a direct relationship between the quality of life, as it is perceived by the patients, and the quality of the health status, which is more important than the relationship between the quality of life and the other objectives measured by WHOQOL scale. This study also shows that for the Romanian patient diagnosed with osteoporosis, who is enclosed in the age limits of this study, the health status represents the main driver of monitoring the quality of life.

Evaluation of adherence to anti-osteoporosis treatment from the socio-economic context.

Osteoporosis is a disease characterized by the reduction of the bone mass and the modification of the bone architecture, which leads to the risk of fracture of the fragile bones, this being the main clinical consequence of the disease. At the same time, osteoporosis is not only a problem by itself, but it is very important from the point of view of the consequences it may produce. Among its consequences, fractures should be mentioned especially in elders, their presence finally leading to an important decrease in the quality of life or even to death. Osteoporosis affects a high amount of persons, preponderantly elders, being considered a very important problem as the society we are talking about deals with the problem of aging. Socio-economical factors and their impact in the development of different pathologies have been seriously analyzed, especially by the western school of medicine. The aim of the current study is to evaluate the adherence to the treatment for osteoporosis of patients diagnosed with osteoporosis or in whom this diagnosis was taken into consideration by the physician, according to some characteristics identified as being the most relevant by a group of specialists. 210 patients were evaluated in this study during January 2011 and December 2013. This study highlighted the way patients with a real or presumptive diagnosis of osteoporosis adhere to the treatment for this disease according to the conditions considered relevant by a team of rheumatologists. It is important to notice that, still from the beginning, once the duration of the disease grows, patients become more and more conscious of the seriousness of the disease and more and more of them adhere to the treatment.

Functional variants of ERAP1 gene are associated with HLA-B27 positive spondyloarthritis.

We investigated two nonsynonymous variants (rs30187 and rs27044) of ERAP1 gene in HLA-B27 positive individuals (150 spondyloarthritis and 108 controls) and in general ankylosing spondylitis (AS) patients (n = 137) vs random controls (n = 139). Both single nucleotide polymorphisms (SNPs) were associated with the risk of spondyloarthritis [odds ratio (OR) 1.80, 95% confidence interval (CI) 1.24-2.62, P = 0.001 for rs30187, OR 1.58, 95% CI 1.07-2.34, P = 0.02 for rs27044]. The CC haplotype was a protective factor (P = 0.002), while the TG haplotype was a risk factor (P = 0.01) for spondyloarthritis. The SNP rs30187 was also associated with the risk of HLA-B27+ AS. For the general group of AS, the carriers of minor alleles showed an increased risk for the disease (OR 1.92, 95% CI 1.17-3.13 for rs30187, OR 1.74, 95% CI 1.08-2.80 for rs27044). This is the first study that shows the association of ERAP1 gene variants and haplotypes with HLA-B27 positive spondyloarthritis.

Anti-cyclic citrullinated peptide antibodies in psoriatic arthritis--cross-sectional study and literature review.

RATIONALE: Anti-CCP antibodies are detectable not only in rheumatoid arthritis (RA), but also in psoriatic arthritis (PsA). It is possible those anti-CCP antibodies are associated with features of PsA and that these auto-antibodies are useful in distinguishing PsA from RA. OBJECTIVE: to evaluate the prevalence and the associations of anti-CCP antibodies in PsA patients; to evaluate the usefulness of anti-CCP antibodies in distinguishing PsA from RA. METHODS AND RESULTS: The inquiry was designed as a cross-sectional study of 41 PsA patients, 139 RA patients and 147 normal subjects, which recorded demographic data, disease activity and serology: rheumatoid factor (RF), anti-CCP antibodies. Five PsA patients (12.2%) were anti-CCP positive. Compared to anti-CCP negative PsA patients, anti-CCP positive PsA patients had a more frequently a polyarticular disease pattern (p = 0.005), they were more frequently treated with biologics (p = 0.015) and less frequently with classic disease-modifying drugs (p < 0.001). An optimal positive cutoff value for anti-CCP titer was determined (11.6 U/mL), over which it is highly probable that a known PsA patient actually has RA and psoriasis. DISCUSSION: The more aggressive the disease of anti-CCP positive PsA patients indicates the need of a more intensive management regarding anti-rheumatic treatment and follow-up. Anti-CCP antibodies can be a useful tool in differentiating PsA from RA, especially in RA-like forms of PsA, which present no elements pertaining to spondyloarthropathies.

Ultrasound in rheumatoid arthritis: volar versus dorsal synovitis evaluation and scoring.

BACKGROUND: Assessment of synovitis in rheumatoid arthritis (RA) is a major issue for a proper treatment administration; it has been proven that ultrasound (US) examination could be of valuable help and it is currently being investigated as a possible outcome measure for the disease. It is, though, of greatest importance to accurately establish the place of US scores among the already validated outcome measures, according to Outcome Measures for Rheumatoid Arthritis in Clinical Trials (OMERACT) filter. The present study is designed to compare the results of gray-scale ultrasound (GSUS) and Power Doppler ultrasound (PDUS) additive scores, separately calculated for volar and dorsal aspects of the hand, with physical examination, patient's evaluation of disease pain and global activity on Visual Analogic Scale (VAS) and traditional scores for disease activity assessment (DAS28, CDAI, SDAI, HAQ). The final aim is to prove the advantages of volar US evaluation in RA patients. METHODS: 42 RA patients have been clinically evaluated for pain and swelling of their hand joints, completed VAS and HAQ questionnaires and underwent both volar and dorsal sonography of the hands during the same day. The US examiner was blinded to clinical assessments and lab results. For each patient 20 joints were assessed by sonography (radiocarpal, intercarpal, metacarpophalangeal (MCP) 2-5, proximal interphalangeal (PIP) 2-5). Carpal joints were only evaluated from dorsal view, while MCPs and PIPs were evaluated both from dorsal and volar aspect resulting a total of 36 distinct evaluations for each patient. GSUS synovial hypertrophy was assessed both by quantitative measurement and semiquantitative scale (0-3 grades); Doppler signal (PDUS) was recorded on a semiquantitative scale (0-3 grades). The semiquantitative grades for both GSUS and PDUS evaluation of each joint were added and the sum was defined as the Echographic Score (ES) of each patient. Separately, we added the semiquantitative grades for volar and dorsal side, resulting in Volar ES (VES) and Dorsal ES (DES) of each patient. RESULTS: We found ESs correlated with other activity scores: DAS28, CDAI, SDAI, HAQ. Correlations with clinical indices as CDAI and SDAI were stronger for VES than for DES. US discovered more synovitis than clinical examination. CONCLUSION: VES is a suitable reflection of RA activity and volar US examination should accompany the dorsal one both in clinical practice and in clinical trials.

HLA-C locus and genetic susceptibility to psoriatic arthritis in Romanian population.

We determined the distribution of human leukocyte antigen-C (HLA-C) allelic groups in a cohort of psoriatic arthritis (PsA) patients and a control population of Romanian ethnicity. A nominal association of HLA-C*06 with susceptibility to PsA was observed [P = 0.014, p(corr) > 0.05, odds ratio (OR) 2.1, 95% confidence interval (CI) 1.08-4.46]. When subanalyzing data according to PsA clinical phenotypes, association was noticed between HLA-C*06 and PsA with psoriasis onset before 40 years (p(corr) = 0.013, OR 3.7, 95% CI 1.58-9). This first report from Romania confirmed the association of HLA-C*06 with type I psoriasis in PsA patients. Other study findings, such as the relationship between HLA-C*06 and spondylitis or the protective effect of HLA-C*07 for the polyarthritis clinical phenotype of PsA, are of preliminary character and require verification.

Distribution of HLA-B27 in Romanian spondyloarthritides patients.

The analysis of 310 Romanian spondyloarthritides patients confirmed the association of the HLA-B27 marker with the susceptibility to different diseases of this group. For ankylosing spondylitis, the HLA-B27 frequency in Romanian patients (72.1%) was similar to that found in several regions in the Mediterranean area.

Early and late effect of infliximab on circulating dendritic cells phenotype in rheumatoid arthritis patients.

The aim of this study was to analyze the phenotype of circulating dendritic cells (DCc) in rheumatoid arthritis (RA) patients before and after treatment with infliximab (at 24 h and 6 months) and the correlation between these changes and the clinical response to treatment. Sixteen patients with RA were recruited and clinical status was determined using the Disease Activity Score 28 (DAS28). All patients had active disease (mean DAS28 = 5.96) and were suitable for treatment with infliximab. Samples of peripheral venous blood were obtained before administration of the first dose of infliximab and again at 24 h and 6 months after treatment. DCc populations were analyzed by flow cytometry. At 24 h, there were no differences in the clinical status of the patients. However, we found a decrease in CD11c+ and, to a lesser extent, CD123+ DCc percentages. The expression of CD83, the most important activation marker for DC, was also shown to be decreased 24 h after infliximab therapy. After 6 months of treatment, all patients showed significant clinical improvement (mean DAS28 = 3.64, p < 0.001) and expression of the activation marker on DCc remained low. In conclusion, this study supports the role of tumor necrosis factor (TNF)-alpha blockade in preventing the maturation of DCc and in reducing the expression of their activation markers. Although the clinical response to infliximab was not observed after 24 h, DCc activation was strongly reduced by anti-TNF-alpha therapy. After 6 months of treatment, current data show a less active phenotype of DCc associated with clinical improvement in all patients in the study.
