Disease pattern of spondyloarthropathies in Spain: description of the first national registry (REGISPONSER) extended report

The national registry of spondyloarthropathies (REGISPONSER) is launched to classify patients with this group of diseases treated in Spanish rheumatology clinics. This manuscript describes the methodological and organizational background as well as characteristics of patients finally included, and provides a comparative analysis between characteristics of both ankylosing spondylitis and undifferentiated spondyloarthropathy groups of patients. Twelve members of the GRESSER group have participated in the registry, for a one-year recruitment period. All consecutively registered adult patients treated in their clinics met the classification criteria of the European Spondyloarthropathies Study Group (ESSG). Data collected reflect the socio-demographic characteristics, as well as disease activity and functional status, clinical form at onset, treatment used and quality of life; all measured by standard instruments. Throughout 1 yr, 1385 patients have been included in the registry: 939 males (68%) and 440 females (32%), with an average age of 47 +/- 13 years (mean +/- s.d.), and an average disease duration of 12 +/- 9 years. Diagnoses of the included patients were: AS (n = 842, 61%), PsA (n = 290, 21%), u-SpA (n = 205, 15%), reactive arthritis (n = 16, 1.2%), inflammatory bowel disease arthritis (n = 13, 0.9%) and JCA-spondyloathropathy (n = 13, 0.9%). Regarding clinical form, 54% had axial disease, 20% peripheral disease, 24% mixed disease and 0.6% isolated enthesitic form. Low-back pain was the first symptom reported in 53% of the patients, and most common extra-articular disease manifestations were psoriasis (25%), anterior uveitis (16%) and intestinal inflammatory disease (4%). Some kind of work disability was reported by 353 patients (25.5%). Such databases are very useful to obtain information about characteristics of SpA patients treated in a certain location or following a specific treatment practice, and provide a tool for assessing the impact of the disease. Data collected in this registry provide an appropriate clinical and demographic profile of patients suffering from SpA in Spain.

Predictors of infusion reactions during infliximab treatment in patients with arthritis

In the present study we evaluated the impact of baseline antinuclear antibody (ANA) status and use of methotrexate on development of infliximab-related infusion reactions in patients with rheumatoid arthritis (RA) or spondylarthropathies (SpAs), including psoriatic arthritis. All patients with RA (n = 213) or SpA (n = 76) treated with infliximab during the period 1999–2005 at the Department of Rheumatology in Lund, Sweden were included. ANAs were present in 28% and 25% of RA and SpA patients, respectively. Because of differences in baseline characteristics, we used a binary logistic regression model to calculate odds ratios (ORs), adjusting for age, sex and prednisolone dosage. Altogether 21% of patients with RA and 13% of patients with SpA developed infusion reactions (P = 0.126). The OR for development of infusion reactions in RA patients with baseline ANA positivity alone was 2.1. Infliximab without methotrexate and infliximab as monotherapy were associated with ORs of 3.1 and 3.6, respectively. Combining infliximab without methotrexate and ANA positivity yielded an OR for infusion reaction of 4.6. Lower age at disease onset and longer disease duration were associated with infusion reactions (P = 0.012 and P = 0.036, respectively), but age, sex, C-reactive protein, erythrocyte sedimentation rate, Health Assessment Questionnaire and Disease Activity Score-28 at baseline were not. No predictors of infusions reactions were identified in SpA patients. RA patients treated with infliximab without methotrexate, and who are positive at baseline for ANAs are at increased risk for developing infliximab-related infusion reactions.

Effects of high iodine doses in parenteral roentgen contrast media administration on parameters of the pro-/antioxidant balance

The aim of this study was to investigate effects of high iodine doses given parenterally as contrast medium on parameters of lipid status and thyroid hormone status as well as on parameters of the pro/antioxidative balance of spa patients. 29 patients with a comparable indication who had to undergo an angiography were chosen. The blood parameters of these patients were determined before and after the angiographic treatment. No provable changes of the thyroid parameters f-T3, f-T4 and TSH were found after the angiography. In case of enzyme activities, the protective enzymes SOD and GSHPX showed no changes, while the concentrations of peroxides and MDA were increased significantly. Corresponding to this, the total antioxidative status and the vitamin E level decreased significantly. Altogether these results stand for a moderate deterioration of the antioxidative protective potential by the highly iodine containing contrast medium.

Spondyloarthropathies in eastern Asia.

The association between HLA-B27 and the spondyloarthropathies (SpAs) is so strong that it is supposed that the HLA-B27 molecule plays a pathogenetic role. In whites and Indonesians, the frequency of HLA-B27 is about 10%; in Chinese it is about 8%; and in Japanese it is only about 1%. The prevalence of SpA in the Chinese is at least 0.2%, but in native Indonesians, Philippinos, and Malaysians, SpA is rarely seen. Twenty-three subtypes (B*2701-B*2723) have been distinguished. These subtypes are not equally distributed over the world. In most countries the distribution of the subtypes among HLA-B27 SpA patients is the same as that among the normal HLA-B27-positive population. In China, the subtype B*2704 is frequent and the prevalence of SpA is high. Native Indonesians, however, mostly have subtype B*2706, and SpA is rarely seen in this population. It was shown that B*2706, probably like B*2709 in Sardinia, is not associated with SpA. The difference between the SpA-associated and non-SpA-associated subtypes is limited to only two amino acid residues (114 and 116) at the bottom of the peptide-binding groove of HLA-B27. This small difference between health and disease rewards studies for different peptide-binding capacities and may help us characterize the peptides that are involved in the pathogenesis of SpA. The differences in disease associations in these countries also have clinical implications. In Southeast Asia, HLA-B27 typing without subtyping has less clinical usefulness than in parts of the world where B*2706 is rarely seen. When native Indonesians, Malaysians, or Philippinos are suspected of having ankylosing spondylitis or a related SpA, it is worth asking if they had white or Chinese ancestors. If native HLA-B27-positive Indonesians (with subtypes other than B*2706) develop SpA, the clinical features are not different from those in other parts of the world. In the Chinese population on the mainland and in Taiwan, juvenile SpA is frequently seen. The onset is often a peripheral arthritis or enthesitis.

The Change of Well-Being Associated with Spa Therapy

Objective: The present exploratory study sought to examine the changes of well-being associated with 3 weeks of resort based spa therapy. This is a traditional form of health enhancement incorporating balneotherapy, physical therapies, and health education in an inpatient setting. Patients and Method: Subjects were spa patients (n = 153, mean age 58 years) with chronic pain and other age related complaints of moderately higher than normal prevalence. The well-being variables were vegetative complaints, pain, fatigue, positive and negative mood, and health satisfaction assessed at the beginning and end of spa treatment as well as 5 weeks and 12 months thereafter. Results: Well-being improved significantly in all variables during spa therapy, the improvement continuing with a slight deterioration at 5 weeks after the stay. After 12 months, vegetative complaints and fatigue had again reached pre-spa levels, whereas pain, positive and negative mood as well as health satisfaction remained improved. Both patients with high and low levels of pain increase their well-being, although pain patients showed greater improvements in some of the measures. Subjects not responding to spa therapy were older and showed less health satisfaction. Conclusions: The results suggest that spa therapy may be a powerful tool in enhancing well-being in progressed middle aged adults with common health impairments.

Nerve Growth Factor (NGF) Autoantibodies and NGF in the Synovial Fluid: Implications in Spondylarthropathies

We investigated the presence of nerve growth factor (NGF) autoantibodies and NGF in the synovial fluid (SF) of patients with different forms of chronic arthritis such as spondylarthropathy (SpA), rheumatoid arthritis (RA), calcium pyrophosphate dihydrate crystal deposition disease (CPPD) and osteoarthritis (OA) and compared them to their levels in serum. NGF autoantibodies were detected by ELISA and by their capacity to immunoprecipitate NGF and to inhibit its biological activity. NGF was measured with a two-site enzyme-linked immunosorbent assay. Significantly high NGF autoantibody levels (p < 10(-4)) and high frequency of detectable NGF (p < 0.01) were observed in the SF of SpA patients and to a lesser degree in RA patients as compared to CPPD and OA patients. In the serum high frequency of detectable NGF was observed only in RA patients. These results suggest a role of NGF autoantibodies and NGF in joint inflammation especially in spondylarthropathies.

Selective non-surgical management of subperiosteal abscess of the orbit: computerized tomography and clinical course as indication for surgical drainage

Subperiosteal abscess of the orbit (SPA) in childhood is an uncommon but serious sequela of sinusitis, with partial or complete visual loss as the most common complication. Traditional management of SPA has combined systemic antibiotics with immediate surgical drainage. The records of 120 children admitted from 1982–1986 with the diagnosis of periorbital or orbital cellulitis were reviewed. Ten cases of SPA were documented by CT scan (8%). Antecedent ethmoid sinusitis was present in all cases. Five SPA patients were managed with intravenous antibiotics and nasal decongestants alone. All had complete clinical and radiographic resolution without complication. The remaining 5 patients underwent surgical drainage. Two patients required immediate drainage due to total ophthalmoplegia upon presentation. One case of postoperative epidural abscess occurred one week after external fronto-ethmoidectomy among these two patients. The remaining 3 patients did not respond adequately to medical therapy alone and underwent surgical drainage without complication. Length of hospital stay in both medical and surgical groups was similar. We conclude that SPA can be safely managed by medical therapy alone in selected cases. Criteria for surgical intervention of documented SPA while on optimal medical therapy should include: worsening of visual acuity or ocular motility, or failure to improve clinically within 48 h. The presence of SPA alone should no longer be considered an absolute indication for surgery.

Sexual development and life of psychiatric female patients.

Using a structured interview and four questionnaires we examined the sexual development and life in the following groups of psychiatric female patients: 51 with schizophrenia, 50 with manic-depressive psychoses, 50 with neuroses, 30 with hysterical psychopathic personality, and 20 with anorexia nervosa. The results were compared with a control group of 101 gynecological spa patients. The sexual development of the schizophrenic patients was found to be retarded, whereas that of the patients with anorexia nervosa accelerated in the initial stages. The sexual development of patients with hysterical personality was found to be disharmonious. No differences were found between patients with manic-depressive psychoses and the control group as far as the sex life in adulthood is concerned. However, all the other groups of psychiatric patients showed decreased sexual activity and/or reactivity. Sexual dysfunctions in the female psychiatric population are frequent, especially with schizophrenic patients, females with anorexia nervosa, and with hysterical personality. The etiological factors responsible for these sex disturbances are different in the individual groups of psychiatric patients.
