Objective Epratuzumab, a monoclonal antibody that targets CD22, modulates B cell signaling without substantial reductions in the number of B cells. The aim of this study was to report the results of 2 phase III multicenter randomized, double-blind, placebo-controlled trials, the EMBODY 1 and EMBODY 2 trials, assessing the efficacy and safety of epratuzumab in patients with moderately to severely active systemic lupus erythematosus (SLE). Methods Patients met ≥4 of the American College of Rheumatology revised classification criteria for SLE, were positive for antinuclear antibodies and/or anti-double-stranded DNA antibodies, had an SLE Disease Activity Index 2000 (SLEDAI-2K) score of ≥6 (increased disease activity), had British Isles Lupus Assessment Group 2004 index (BILAG-2004) scores of grade A (severe disease activity) in ≥1 body system or grade B (moderate disease activity) in ≥2 body systems (in the mucocutaneous, musculoskeletal, or cardiorespiratory domains), and were receiving standard therapy, including mandatory treatment with corticosteroids (5-60 mg/day). BILAG-2004 grade A scores in the renal and central nervous system domains were excluded. Patients were randomized 1:1:1 to receive either placebo, epratuzumab 600 mg every week, or epratuzumab 1,200 mg every other week, with infusions delivered for the first 4 weeks of each 12-week dosing cycle, for 4 cycles. Patients across all 3 treatment groups also continued with their standard therapy. The primary end point was the response rate at week 48 according to the BILAG-based Combined Lupus Assessment (BICLA) definition, requiring improvement in the BILAG-2004 score, no worsening in the BILAG-2004 score, SLEDAI-2K score, or physician's global assessment of disease activity, and no disallowed changes in concomitant medications. Patients who discontinued the study medication were classified as nonresponders. Results In the EMBODY 1 and EMBODY 2 trials of epratuzumab, 793 patients and 791 patients, respectively, were randomized, 786 (99.1%) and 788 (99.6%), respectively, received study medication, and 528 (66.6%) and 533 (67.4%), respectively, completed the study. There was no statistically significant difference in the primary end point between the groups, with the week 48 BICLA response rates being similar between the epratuzumab groups and the placebo group (response rates ranging from 33.5% to 39.8%). No new safety signals were identified. Conclusion In patients with moderate or severely active SLE, treatment with epratuzumab + standard therapy did not result in improvements in response rates over that observed in the placebo + standard therapy group.

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. [ABSTRACT FROM AUTHOR]

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 > 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 = 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.

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. [ABSTRACT FROM AUTHOR]

Background: rheumatoid arthritis (RA) is associated with loss of overall functionality of the locomotion system and it is connected with substantial economic losses. Objective: to describe the clinical characteristics and healthcare resource utilization characteristics and to analyze the correlations in a cross-sectional sample of 206 patients in Romania. Method: RA cases have been enrolled from southern and western part of the country, covering a surface of 23 counties. Results: particularly in the literature data, Romanian RA patients become work disabled at 5.65 ± 5.99 years old after the diagnosis. At cohort level, retirement in the first year after RA diagnosis is of 22.9%. From those, 13% were treated with biologic DMARDs; those on non-biologic DMARDs were 28.6%. In oral therapy group the most prescribed drug is lefunomide (61.2%). RA has an important impact on pain, function and utility, influenced by social factors. Patients' follow up is often based on hospitalization. Conclusion: currently, when the clinician may choose for one certain therapy or another, the social influence is still overwhelming at all the evaluation levels in RA patients, as well as at economic impact.
