Abstract: Osteonecrosis is a clinical entity characterized by death of bone marrow and trabecular bone as a result of disruption of blood supply to the bone (1,2). Other aspects of this condition include avascular necrosis, aseptic necrosis, and osseous ischemic necrosis of bones. Osteonecrosis is classified into two main forms; post-traumatic and nontraumatic. The post-traumatic form of osteonecrosis usually develops as a result of traumatic displacement of bone fragments, which leads to impaired blood supply and ischemia to the affected bone. Osteonecrosis of the femoral head is common following fracture of the femoral neck. A variety of systemic diseases and clinical conditions are associated with nontraumatic osteonecrosis. These include autoimmune rheumatic diseases, alcoholism, pregnancy, Gaucher's disease, thrombophilia, corticosteroid therapy, Sickle-cell anemia, pancreatitis, inflammatory bowel diseases, and use of cytotoxic drugs and others. Idiopathic forms of osteonecrosis have also been reported (2-4). Among the rheumatic diseases, osteonecrosis is strongly associated with systemic lupus erythematosus (SLE) (5). However, osteonecrosis has been diagnosed in patients with primary antiphospholipid syndrome (APS) (6), rheumatoid arthritis (7), and systemic vasculitis (8). This article reviews the causes, clinical and epidemiological features, diagnosis, and treatment options for osteonecrosis among patients with SLE.

Abstract: Autoimmune rheumatic diseases and lymphocytic malignancies are related and this association is bidirectional. Lymphomas occur more frequently in the course of autoimmune disease and autoimmune rheumatic manifestations occur in the course of lymphocytic malignancies. An increased incidence of malignant lymphocytic diseases is present in patients with rheumatoid arthritis, systemic lupus erythematosus, Sjögren's syndrome, and autoimmune thyroid disease. Descriptions of lymphocytic malignancies among other autoimmune rheumatic disease have been published. In some patients, the malignant disease is diagnosed months or years before the appearance of the rheumatic disease.

Abstract: BACKGROUND: "Ultrasonic biopsy" (U-B) is a noninvasive screening technique to detect early atherosclerotic plaques and arterial wall changes. AIM: To identify atherosclerosis (AS) in the common carotid artery (CCA) and common femoral artery (CFA) of patients with rheumatoid arthritis (RA) and their matched controls. METHODS: Fifty-seven consecutive RA patients were enrolled in the study. Controls were matched by age, sex, ethnicity, and AS risk factors. All patients and controls underwent U-B study of the CCA and CFA. The U-B features were classified and scored as follows: Class A, normal (score 0); Class B, interface disruption (score 2); class C, intima-media (I-M) granulation (score 4); Class D, plaque without hemodynamic disturbance (score 6); Class E, stenotic plaque (score 8); and Class F, plaque with symptoms (score 10). Total score per patient was calculated. Classes A-B indicate an intact media or minimal interphase changes; classes D-F point to a significant medial involvement. Class C signifies a borderline lesion, with a potential for regression to normal, being unchanged, or progression to a plaque. RESULTS: Mean ages were 52.1 years for RA and 51.4 years for controls (P = 0.81). Eighty-six percent of the patients and 85% of controls were women. The mean disease duration of RA was 12.8 years. Frequencies of risk factors among the RA patients compared with controls were hypertension (28% versus 32%), smoking (37% versus 29%), dyslipidemia (23% versus 25%), diabetes mellitus (DM) (14% versus 14%), and family history of cardiovascular disease (CVD) (4% versus 7%). Forty-five percent of the RA patients had at least a single Classes D-F lesion (plaque) in 1 of the 4 vessels tested, compared with 40% in the control group (P = 0.19). The mean total U-B scores of the RA patients and controls were not significantly different (8.87 versus 9.49, P = 0.7). Univariate analyses have shown that the development of plaques in RA patients was associated with age >50 years, disease duration, hypertension, dyslipidemia, and smoking. Multivariate analysis found plaques to be strongly associated with age above 50 years and dyslipidemia. CONCLUSION: In unselected RA patients, besides classic AS risk factors, older age and longstanding disease may help predict the development of a severe morphological expression of AS.

Abstract: BACKGROUND: A high incidence of abnormal pulmonary function tests has been reported in cross-sectional studies among patients with rheumatoid arthritis. Few patients have been enrolled in longitudinal studies. OBJECTIVES: To perform PFT in rheumatoid arthritic patients without pulmonary involvement and to identify variables related to changes in PFT over 5 years of follow-up. METHODS: Consecutive RA patients underwent PFT according to recommendations of the American Thoracic Society. All surviving patients were advised to repeat the examination 5 years later. RESULTS: PFT was performed in 82 patients (21 men, 61 women). Their mean age was 55.7 (15.9) years and the mean RA duration was 11.1 (10) years. Five years later 15 patients (18.3%) had died. Among the 67 surviving patients, 38 (56.7%) agreed to participate in a follow-up study. The initial PFT revealed normal PFT in only 30 patients (36.6%); an obstructive ventilatory defect in 2 (2.4%), a small airway defect in 12 (17%), a restrictive ventilatory defect in 21 (25.6%), and reduced DLco in 17 (20.7%). Among the 38 patients participating in the 5 year follow-up study, 8 developed respiratory symptoms, one patient had a new obstructive ventilatory defect, one patient developed a restrictive ventilatory defect, and 5 patients had a newly developed small airway defect. The DLco had improved in 7 of the 8 patients who initially had reduced DLco, reaching normal values in 5 patients. Over the study period a new reduction in DLco was observed in 7 patients. Linear regression analyses failed to identify any patient or disease-specific characteristics that could predict a worsening in PFT. The absolute yearly decline in forced expiratory volume in 1 sec among our RA patients was 47 ml/year, a decline similar to that seen among current smokers. CONCLUSIONS: Serial PFT among patients with RA is indicated and allows for earlier identification of various ventilatory defects. Small airways disturbance was a common finding in our RA patients.

Abstract: OBJECTIVE: To investigate the prevalence of antipolymer antibody (APA) in patients with fibromyalgia (FM) and to examine its association with FM severity symptoms. METHODS: The study population consisted of 79 FM patients and 75 controls: 32 with psoriatic arthritis and 43 with rheumatoid arthritis APA levels were indirectly assayed using a commercial ELISA kit from Corgenix (Westmister, Colorado, USA). Optical density (OD) values were recorded on duplicates of each of the reference and patient samples. Among clinical variables we investigated pain, measured according to visual analog scales (VAS: 0-100), fatigue, stiffness, anxiety, depression, all measured by VAS (0-100), and health status measured by Fibromyalgia Impact Questionnaire (FIQ). RESULTS: Sixteen of the 79 FM patients (20.3%) and 12/78 controls (15.4%) were positive for APAs (P = 0.536). Following ROC analysis, area under curve (AUC) was 0.49 (95% CI: 0.40, 0.58). Focusing on FM patients, we observed a correlation between APA titre and pain (tau: - 0.221; P = 0.020) and fatigue (tau: - 0.205; P = 0.032) at univariate analysis. Binomial regression analysis, controlling for clinical and demographic variables, showed that pain (PPR: 0.923; P = 0.007) and fatigue (PPR: 0.948; P = 0.024) were significantly associated with APA test sensitivity. CONCLUSIONS: APA test exhibited a low sensitivity in FM patients and it did not distinguish this group of patients from the controls enrolled in this study. Interestingly, positive APA test prevalence increased with less severe pain or fatigue.

Abstract: The aim of the study was to assess the quality of life (QOL) and the psychological status of parents of children with juvenile chronic arthritis (JCA). The QOL, anxiety and depression of the parents of 28 children with JCA were evaluated and compared to those of the parents of 28 healthy children. Mothers of JCA children and mothers of healthy children reported similar QOL. The reported anxiety and depression levels were similar for mothers and fathers in both groups. The parents of children with pauciarticular-type JCA reported lower QOL and higher levels of anxiety and depression than the parents of children with other types, namely polyarticular and systemic JCA. These findings may be explained by the fact that the pauciarticular patients had shorter disease duration and were less frequently seen in the outpatient clinic. The QOL of mothers of children with JCA was found to be slightly impaired in the group of children with pauciarticular JCA. Future larger studies are needed to confirm these results, as the number of subjects in the three groups was rather low.
