Paget's disease of bone in early adult life.

OBJECTIVE: To determine the range and activity of the clinical and biological features of patients aged <40 with Paget's disease of bone. METHODS: A retrospective two centre study of 314 patients with Paget's disease of bone from two university hospitals. The disease was diagnosed by radiological, serum alkaline phosphatase (AP) levels, or clinical features, and bone scintigraphy in most patients. Demographic data, reason for diagnosis, bones affected, disease extent using Coutris' index, complications during progression, and disease activity using Renier's index were assessed. Patients over and under 40 were compared. RESULTS: 18/314 (5.7%) patients were diagnosed before the age of 40; median (SD) age was 35.4 (5.5) (range 18-40) and AP 555.6 (566.3) IU/l (range 70-1949). Coutris' extension index was 12.8 (10.5) and Renier's activity index 35.9 (31.9). Younger patients had more affected bones (p<0.05) than those aged >40, higher level of extension (p<0.05), higher AP value (p = 0.05), and greater incidence of thoracolumbar spine disease. Disease activity did not differ significantly between the groups. CONCLUSIONS: Paget's disease diagnosed before the age of 40 is more extensive but not more active, with higher AP values than in those diagnosed after age 40.

Occult liver involvement by polyarteritis nodosa.

The diagnosis of panarteritis nodosa is usually difficult because of the variability of clinical manifestations. Herein is presented a case of occult liver involvement by polyarteritis nodosa. Several biopsies were performed but the diagnosis was made with the contribution of a hepatic arteriography.

Association of systemic lupus erythematosus and hypermobility.

OBJECTIVE: To investigate joint laxity in patients with systemic lupus erythematosus (SLE). SETTING: University Hospital. METHODS: 81 patients with SLE (1999 American College of Rheumatology criteria; 72 (89%) women and nine (11%) men, mean age 42.9 (SD 16.1) years), who regularly attended a specialist SLE clinic were examined. The control group comprised 280 patients attending a general practitioner (193 (69%) women and 87 (31%) men, mean age 44.7 (SD 11.2) years). Joint laxity was measured according to the criteria of Beighton et al (total score 4 or more). A regression analysis was performed. RESULTS: Thirty nine (48%) patients with SLE and 42 (15%) of the control group were hypermobile. A logistic regression model was developed. The odds ratio of the association between laxity and SLE after adjustment for age and sex was 2.31 in the group younger than 49 years, and 17.99 in the group aged 49 years or older. Neither the clinical and analytical profile nor the use of corticosteroids was related to joint laxity. CONCLUSION: Patients with SLE showed more hypermobility than controls. Hypermobility was more profound in older patients with SLE (> or =49 years). Joint laxity was not associated with any clinical or analytical pattern. Treatment with corticosteroids was not related to joint laxity.

Musculoskeletal manifestations in patients positive for human immunodeficiency virus: correlation with CD4 count.

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.

Achilles tendinitis as the presentation form of Löfgren's syndrome.

Löfgren's syndrome is characterised by bilateral hilar adenopathy arthritis and erythema nodosum. Achilles tendinitis as the presentation form of Löfgren's syndrome is very unusual. Herein we present a case of bilateral achilles tendinitis as the presentation form of Löfgren's syndrome.

Abnormal fatty acid pattern in rheumatoid arthritis. A rationale for treatment with marine and botanical lipids.

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.
