Bacillary angiomatosis (BA) is a recently discovered multisystem bacterial infectious disease seen in the setting of immune suppression due to the human immunodeficiency virus (HIV). A case of an HFV-infected patient with osteolytic bone involvement is reported. [ABSTRACT FROM PUBLISHER]

The purpose of this study is to describe the clinical and radiological manifestations of patients with the synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome. Retrospective study (1984-2007) was performed in a single center. All patients with the SAPHO syndrome were included. Fifty-two patients were included: 26 male, mean age at diagnosis is 42±12 years. Ostearticular involvement was present before cutaneous involvement in 59.6% of patients and concomitantly in 23.5%. Anterior chest pain was the commonest clinical manifestation, it was present in 38 patients (73%), followed by peripheral arthritis in 17 patients (32%), and sacroliliac pain in 14 patients (26.9%). Cutaneous involvement was present in 33 patients (63.5%). HLA B27 antigen was present in eight patients (17.7%). Bone scintigraphy showed an increased uptake in 42 patients (93.3%). The location of the uptake was mainly in sternoclavicular and manubriosternal joints. CT scan was performed in all "hot joints" showing sclerosis, erosions, hyperostosis, and soft tissue involvement. Refractory patients were treated mainly with pamidronate. Although SAPHO syndrome is an entity that share features that fit into a variety of established disease categories, the present study has a homogenous clinical and radiological pattern that gives support to believe that the SAPHO syndrome is an isolated clinical entity.

HIV-1-infected patients with osteoporosis were randomly assigned to alendronate 70 mg once-weekly plus dietary counselling (n = 11) or diet counselling alone (n = 14). At week 96, 27% of patients on alendronate versus 96% of controls presented with osteoporosis. Spine bone mineral density (BMD) increases were detected at week 48, and progressed thereafter. Improvements in trochanter BMD were obtained after 2 years. Once-weekly oral alendronate may be an effective and safe treatment for HIV-1-associated osteoporosis.

Objective: To estimate the prevalence of anterior atlantoaxial subluxation (AAS) in patients with rheumatoid arthritis (RA), and to analyse its association with disease markers., Methods: Cross-sectional analysis of a cohort of RA patients randomly selected from the clinical registries of 34 centres. AAS, defined as an atlantoaxial displacement in cervical spine X-rays greater than 3 mm on flexion films, was actively searched for. Bivariate and multivariate analysis was performed to examine its association with clinical, functional, and treatment variables., Results: AAS was found in 88 out of 736 patients with available cervical radiographs, (prevalence and 95% confidence interval [CI]: 12% [9.7-14.2]). The presence of AAS was highly associated with a Larsen score (0-150) over 50 (OR and 95% CI: 5.31 [2.68-10.55]), RA duration of more than 10 years (4.48 [2.70-7.44]), disease onset before age 50 (4.15 [2.42-7.12]), eye involvement (3.93 [1.63-9.46]), and previous RA related surgery (3.90 [2.46-6.19]). No association was found with rheumatoid factor. Multivariate analysis showed that a disease onset before the age of 50, the number of previous DMARD, and, above all, a Larsen score greater than 50 were important independent factors associated with AAS. There is a 33% increased risk for AAS every 10 units up in the Larsen score., Conclusion: AAS is frequent in RA patients, particularly in those with markers of erosive disease.

Objective: To assess the criteria for remission based on Disease Activity Score 28 (DAS28) and DAS28-3 (excluding patients' evaluation of disease activity) compared to American College of Rheumatology (ACR) preliminary criteria in established rheumatoid arthritis (RA), and to examine the value of each ACR criterion individually., Methods: The EMECAR study was designed to assess the burden of comorbidity and inflammatory activity for RA in Spain. A random sample of 788 patients with RA from 34 Spanish centers was selected. Remission was defined by preliminary ACR criteria applied specifically and the clinical activity assessed by the DAS28 and the DAS28-3. A receiver operating characteristics curve analysis was performed to identify cutoff values with the highest usefulness in defining remission on both DAS indices., Results: Thirty-two patients (4.1%) were in ACR-defined remission, 62 (7.9%) if fatigue was excluded from the criteria. The frequency of any single criterion that patients in remission fulfilled: no fatigue and joint pain by anamnesis in 31 patients (96.9%); morning stiffness < 15 min in 26 (81.3%); no swelling in joints in 21 (65.6%); normal erythrocyte sedimentation rate (ESR) in 29 (90.6%); and no joint tenderness in 21 (65.6%) patients. The positive predictive value for remission of each criterion: normal ESR 6.5%; morning stiffness < 15 min 8.4%; no fatigue 8.7%; no joint tenderness 13%; no swelling in joints 15.8%; and no joint pain by anamnesis 27.7%. The DAS28 cutoff values with higher discriminatory power for remission were 3.14 (sensitivity 87%; specificity 67%) when all the ACR criteria were used, and 2.81 (sensitivity 84%; specificity 81%) when fatigue was omitted. The equivalent cutoffs for the DAS28-3 were 3.52 (sensitivity 84%; specificity 66%) and 2.95 (sensitivity 82%; specificity 83%), respectively., Conclusion: DAS28 and DAS28-3 are good tools to define remission in established RA. No joint pain by anamnesis is the criterion with the highest value in defining remission, while normal ESR, an absence of morning stiffness, and fatigue are the least effective.

Objective: To quantify the risk of tuberculosis (TB) in an unselected sample of patients with rheumatoid arthritis (RA) compared to the risk in the general population., Methods: The incidence of TB in the general population of Spain was obtained from the National Network of Epidemiological Surveillance reports. The incidence of TB was ascertained from a cohort of 788 patients with RA selected randomly from the registries of 34 participating centers throughout Spain. A patient was considered a TB case only if information about disease symptoms, microorganism identification, and TB treatment were confirmed in the clinical records. The relative risk of TB in RA was calculated by dividing the standardized mean incidence of TB from 1990 to 2000 in the RA cohort by the mean incidence of TB in Spain during the same years., Results: The mean incidence of TB in the general population of Spain from 1990 to 2000 was 23 cases per 100,000. Seven cases of TB were identified in the RA cohort, yielding a mean annual incidence (1990-2000) of 134/100,000 patients. The incidence risk ratio of pulmonary TB in patients with RA compared to the general population is 3.68 (95% CI 2.36-5.92)., Conclusion: We found a 4-fold increased risk of TB infection in patients diagnosed with RA. These results might help to interpret the magnitude of the problem attributable to the introduction of new therapies in RA.

Objective: To determine the adequacy of disease modifying antirheumatic drug (DMARD) prescription to disease activity in patients with rheumatoid arthritis (RA) and to assess whether the reasons for DMARD discontinuation agree with published evidence., Methods: Cross-sectional analysis of the baseline year of a RA cohort (n = 788) randomly selected from the clinical registries of 34 centers. Data about current and previous DMARD use was collected from medical records and confirmed by the patient. Disease activity score (DAS), Health Assessment Questionnaire (HAQ) and Larsen scores, and other clinical data were obtained during the study visit., Results: At baseline visit, 607 patients (77%) were receiving one or more DMARD. Mean DAS, HAQ, and Larsen scores (+/- SD) were: 3.40 +/- 1.22, 1.6 +/- 0.4, and 54.68 +/- 26.37, respectively. Methotrexate (MTX) was the most frequently prescribed DMARD and parenteral gold salts (GS) showed the highest rate of discontinuation. MTX was used as single therapy in a significantly higher proportion (64.3%) than other DMARD (< 50%) and treatment discontinuation due to inefficacy was significantly less frequent (25.5%) than with other DMARD (> 40%). However, the DAS28 was significantly worse in the group treated with MTX in single therapy than in the group treated with GS alone (4.13 vs 3.43; p = 0.032)., Conclusion: Despite the high use of DMARD among Spanish patients with RA, a significant number of them still have poor control of the disease. In addition, our data show a different perception of ineffectiveness depending on the DMARD used. A non-systematic use of objective quantitative tools for assessment of RA activity and some non-evidence based decisions on the management of DMARD may account for these findings.

Background and Aims: A randomized, double-blind, placebo-controlled, multicenter study was conducted to assess the efficacy of 2 g sucralfate suspension in treating gastric mucosal lesions caused by long-term treatment with nonsteroidal anti-inflammatory drugs (NSAIDs)., Methods: Only patients given NSAIDs continuously for at least 2 months with positive fecal occult blood (FOB) and endoscopically confirmed mild to moderate mucosal lesions (Lanza scale, grades 2-4) were included. After 1-week run-in phase, patients were stratified into 2 groups according to gastropathy-related symptoms during the preceding 7 days (symptomatic vs. asymptomatic) and randomized to 2 g (10 mL) of sucralfate suspension or placebo twice a day over a 6-week period. NSAIDs were given according to each patient's dosage schedule and always after meals., Results: Twenty-five patients received sucralfate and 25 received placebo. At the end of the study, 68% (17/25) of patients given sucralfate had no lesions (Lanza grade 0) on endoscopy compared with 35% (8/23) in controls (P = 0.042). The Lanza grades in patients given sucralfate were significantly improved compared with the placebo patients (P = 0.022)., Conclusions: In this target population selected according to positive FOB test and endoscopic evidence of mucosal injury, chronic administration of sucralfate significantly decreased NSAID-induced gastric erosions.

Aseptic diskitis is relatively common. Several rheumatic diseases involving the spine may have this complication. As this condition mimic infectious diskitis, it is important to recognize it. Clinically, it is characterised by vertebral pain of an inflammatory nature, occasionally accompanied by fever and an increase in the erythrocyte sedimentation rate. Radiologically, the decrease in the articular space and the irregularity of the vertebral plates are of particular importance. Although uncommon, it is necessary to bear in mind this possibility when the etiological search for a possible infectious diskitis proves fruitless. A MEDLINE (1986-2000) and PUBMED (1966-2000) search of relevant articles was performed. Descriptors used were aseptic diskitis, spondylodiskitis, pseudodiskitis and pseudoarthrosis.

Objective: To determine the relationship between the CD4+ lymphocyte count and musculoskeletal manifestations of human immunodeficiency virus (HIV) infection., Methods: All patients from 1991 to 1998 who were positive for HIV with osteoarticular manifestations were reviewed retrospectively. HIV positivity was confirmed by ELISA and Western blot. CD4 count was performed by flow cytometry., Results: We studied 74 patients with osteoarticular manifestations. The study group comprised 61 men (82.4%) and 13 women (17.5%) with a mean age of 34.2 years (range 17-62). Fifty-two patients were iv drug users (70.3%). Septic arthritis was present in 20 cases (23.0%), soft tissue infections in 9 cases (12.2%), spondyloarthropathies in 6 cases (8.1%), lymphomas in 9 cases (12.2%), osteomyelitis in 6 (8.1%), and 24 miscellaneous cases (32.4%). The mean CD4 count was as follows: septic arthritis 164.7 cells/mm3, soft tissue involvement 127.1 cells/mm3, spondyloarthropathies 245.8 cells/mm3, lymphoma 132.8 cells/mm3, and osteomyelitis 233.6 cells/mm3., Conclusion: Osteoarticular manifestations in the setting of HIV infection tend to be predominantly infectious. S. aureus is the microorganism most frequently involved. Ostearticular infections always appeared when the CD4 count was < 200 and pyomyositis and lymphoma appeared when CD4 was < 150. CD4 counts may be useful predictors to determine the type of musculoskeletal manifestation.

Objective: To assess the fatty acid pattern in plasma and synovial fluid (SF) in rheumatoid arthritis (RA) and to determine clinical factors related to possible abnormalities., Methods: Thirty-nine patients with RA were included. SF samples were obtained from 9 patients. Disease activity was assessed using the Ritchie Articular Index and erythrocyte sedimentation rate. Fatty acids were assayed with gas liquid chromatography., Result: Decreased levels of eicosapentaenoic acid (p < 0.0001) and total n3 polyunsaturated fatty acids (p < 0.05) were observed in plasma and in joint fluid, respectively. An increase of the substrates of delta-5-desaturase (C20:3n6 and C20:2n6) and decrease of their products (C20:4n6 and C22:4n6) was observed in plasma total lipids and phospholipids. The long chain mono-unsaturated fatty acids (C20: 1n9, C22: 1n9, C24: ln9) were increased in the joint fluid and in plasma phospholipids. Patients with active disease showed a mild decrease of several saturated fatty acids, n3, and n6 polyunsaturated fatty acids. Minor abnormalities or no changes in fatty acid profile were found related to use of steroids, nonsteroidal antiinflammatory drugs, and gold salts, or malnutrition., Conclusion: The fatty acid pattern found in RA (decreased levels of n3 polyunsaturated fatty acids) may explain the beneficial effect of fish oil. Changes in n6 polyunsaturated fatty acids suggest that delta-5 desaturation is decreased and this might facilitate the antiinflammatory effect of botanical lipids in RA.

Objective: To describe the clinical and laboratory features and outcome of patients with remitting seronegative symmetrical synovitis with pitting edema (RS3PE)., Methods: A retrospective multicenter study of patients with RS3PE fulfilling the following criteria: (1) bilateral pitting edema of both hands, (2) sudden onset of polyarthritis, (3) age > 50 years, (4) seronegative for rheumatoid factor (RF)., Results: 27 patients with RS3PE were included, mean age 71.7 years (58-92), 18 men (66.6%) and 9 women (33.3%). Relevant history was noted in 2 patients with polymyalgia rheumatica. Main clinical features were polyarthritis and edema of both hands. Polyarthritis involved metacarpophalangeal joints in 22 patients (81.5%), proximal interphalangeal joints in 19 (70.4%), wrists in 15 (55.5%), shoulders in 13 (48%), elbows in 3 (11.1%), knees in 9 (33.3%), and ankles in 7 (25.9%). All patients were RF negative. Antinuclear antibodies were positive at low titer in 8 patients. Erosions were present in one patient. Two patients developed T lymphoma and one myelodysplastic syndrome., Conclusion: RS3PE is a heterogeneous syndrome the clinical history, presence of erosions, and evolution to hematological diseases in our patients suggest that RS3PE may not be a distinct clinical entity.

We present a 71-year-old man with primary amyloidosis characterized by several outstanding clinical features, namely hip involvement of a pseudotumoral appearance, periarticular osteolytic lesions and a pathological fracture. Kappa light chains in the synovial fluid were observed. The patient survived for 90 months without developing plasma cell dyscrasia, and with preservation of vital functions despite parenchymal involvement of multiple organs.
