Differences in the prevalence and characteristics of metabolic syndrome in rheumatoid arthritis and osteoarthritis: a multicentric study.

The purpose of the study was to examine whether rheumatoid arthritis (RA) patients have higher prevalence of metabolic syndrome (MetS) than osteoarthritis (OA) patients in association with a higher level of chronic systemic inflammation in rheumatoid arthritis. A total of 583 RA and 344 OA outpatients were analyzed in this multicentric study. Metabolic syndrome was defined using the National Cholesterol Education Program Adult Treatment Panel III criteria. A 1.6-fold higher prevalence of MetS was found in patients with OA compared with the RA patients. Among the parameters of MetS, patients with OA had significantly higher levels of waist circumference, systolic blood pressure, fasting blood glucose and triglycerides, whereas HDL cholesterol and diastolic blood pressure values were similar in both groups of patients. Higher values of inflammatory markers [C-reactive protein (CRP), erythrocyte sedimentation rate (ESR)] in MetS than in non-MetS patients and higher prevalence of MetS in patients with CRP level ≥5 mg/L in both RA and OA patients were found. In multivariate logistic regression analysis, significant predictors of MetS were type of arthritis (OA vs. RA; OR 2.5 [95 % CI 1.82-3.43]), age (OR 1.04 [95 % CI 1.03-1.06]) and ESR (OR 1.01; [95 % CI 1.00-1.01]). The significant association between OA and MetS was maintained in the regression model that controlled for body mass index (OR 1.87 [95 % CI 1.34-2.61]). The present analysis suggests that OA is associated with an increased risk of MetS, which may be due to a common underlying pathogenic mechanism.

[RETROSPECTIVE DATA ANALYSIS OF THE PATIENTS WITH INFLAMMATORY JOINT DISEASES TREATED WITH GOLIMUMAB IN CROATIA]. / RETROSPEKTIVNA ANALIZA PODATAKA BOLESNIKA OBOLJELIH OD UPALNIH REUMATSKIH BOLESTI U HRVATSKOJ LIJECENIH GOLIMUMABOM.

Golimumab is a human monoclonal antibody which inhibits tumor necrosis factor-alpha (TNF-α) and is approved for the treatment of inflammatory arthritides (rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis) when the conventional non-pharmacological and pharmacological therapies fail to cause remission or low disease activity. In this retrospective study there were included patients with rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis who were treated in Croatia with golimumab, from June 2011 to June 2013. included and these retrospective data are compared with similar data from clinical trials and other available databases. Standard variables of disease activity and functional ability were observed. Results demonstrated significant efficacy of golimumab regarding lowring the disease activity and imrpving functional ability in pateints with these inflammatory rherumatic disease. In conclusion, in this retrospective study during two years treatment golimumab showed efficacy in decreasing disease activity and imrpove functional ability in patiemts with rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis.

[The treatment of rheumatoid arthritis]. / Lijecenje reumatoidnog artritisa.

Today, the goal of the treatment of rheumatoid arthritis is remission of disease activity which should be achieved through the first 6 months of treatment with conventional disease modifying antirheumatic drugs and tight control principle. The treatment must be adjusted to the state of disease on each visit. In the absence of remission or low disease activity biological drugs are indicated. Tapering or withdrawal of any treatment depends on the judgment of the physician and the patient, and should be considered only after at least 6 months of stable remission.

[Relationship between vitamin D status and bone mineral density in Croatian postmenopausal women]. / Povezanost statusa vitamina D s mineralnom gustocom kosti u hrvatskih zena u postmenopauzi.

The aim of the study was to investigate correlation of vitamin D status meassured as 25-hydoxyvitamin D (25(OH)D) concentration with bone mineral density (BMD) in Croatian postmenopausal women. This study was based on the sample of 194 adult, postmenopausal women aged 50 years or over from Croatia. Assessment of 25(OH)D concentration and BMD by dual-energy xray absorptiometry (DXA) was performed to all participants. The average age of the participants in this study was 60.6 years. The average menopause duration was 11.4 years. Among the included participants only 13.9% of women complied with diagnostic criteria for osteoporosis. Mean serum concentration of 25(OH)D was 49.1 nmol/L (+/-17.1 SD). The prevalence of severe vitamin D deficiency was significantly higher in participants with osteoporosis compared with participants with normal BMD (<30 nmol/L; 29.6% vs. 9.8%). Correlation between serum 25(OH)D concentration and BMD was significant and positive at the proximal femur (r=0.18; p=0.026), and at the femoral neck (r=0.15; p<0.001). The results of this study indicate significant and positive correlation between serum 25(OH)D concentration and BMD meassured at the proximal femur and at the femoral neck in Croatian postmenopausal women.

[The proposal of the Croatian Society for Rheumatology for the treatment of adult rheumatoid arthritis patients with biologics, 2013]. / Prijedlog Hrvatskog reumatoloskog drustva HLZ-a za lijecenje reumatoidnog artritisa odraslih bolesnika bioloskim lijekovima, 2013.

Standardized approach to the patients with rheumatoid arthritis (RA) is one of the requirements of good clinical practice. Croatian Society for Rheumatology (HRD) of Croatian Medical Association (HLZ) updated the Proposed treatment of rheumatoid arthritis (RA) with biologic agents in line with recent findings in rheumatology for the last 3 years. By complying with the agreed standards of treatment we can avoid malpractice and irrational consumption, and to the most patients provide a greater chance for a favorable outcome.

[The proposal of Croatian Society for Rheumatology for anti-TNF-alpha therapy in adult patients with spondyloarthritides, 2013]. / Prijedlog hrvatskog reumatoloskog drustva HLZ-a za primjenu inhibitora TNF-alpha u odraslih bolesnika sa spondiloartritisima, 2013.

Croatian Society for Rheumatology of Croatian Medical Association updated the proposal for the application of TNF-alpha inhibitors in adult patients with spondyloartritides (SpA) in accordance with the new classification of SpA and european recommendations for the treatment of SpA with biologic agents. In this way a standardized method of diagnosis, targeted treatment, monitoring and evaluating outcomes are proposed.

[Tendinopathy]. / Tendinopatija.

Tendons are made of connective tissue and passively transfer force from muscle contraction to the bone and are daily exposed to mechanical loading. They are built of tenocytes inserted in the extracellular matrix in which collagen type I fibers maintain its strength. Stretching the collagen fibers of more than 10% of the original length can cause them to crack. In the development of chronic degenerative tendinopathy there is overlapping of reactive acute tendinopathy, tendon dysrepair (failed healing) and degenerative tendinopathy. Acute condition requires unloading in the first few days and in the chronic phase, it is recommended to exercise even over the limit of pain. The role of clinician is to distinguish reversible from irreversible condition and utilize the remaining reparations potential or to consider surgical treatment methods.

Is the prevalence of arterial hypertension in rheumatoid arthritis and osteoarthritis associated with disease?

In this study, we compare the prevalence of arterial hypertension (HT) in rheumatoid arthritis (RA) and osteoarthritis (OA) patients, exposed to high- and low-grade chronic inflammation, respectively, to assess the possible association between chronic inflammation and HT. A total of consecutive 627 RA and 352 OA patients were enrolled in this multicentric study. HT was defined as a systolic blood pressure (BP) ≥ 140 and/or diastolic BP ≥ 90 mmHg or current use of any antihypertensive drug. Overweight/obesity was defined as body mass index (BMI) ≥ 25, and patients ≥65 years were considered elderly. The prevalence of HT was higher in the OA group than in the RA group [73.3 % (95 % CI, 68.4, 77.7) and 59.5 % (95 % CI, 55.6, 68.4) P < 0.001, respectively]. When the results were adjusted for age and BMI, the HT prevalence was similar in both groups [RA 59 % (95 % CI, 55.1, 63.8) OA 60 % (95 % CI, 58.4, 65.0)]. In both groups, the prevalence of HT was higher in the elderly and those who were overweight than in the younger patients and those with a BMI < 25. Overweight (BMI ≥ 25) and age ≥65 were independent predictors of HT in multivariate logistic regression model, which showed no association between HT and the disease (RA or OA). The results indicate a robust association of age and BMI with HT prevalence in both RA and OA. The difference in HT prevalence between RA and OA is due rather to age and BMI than to the features of the disease, putting into question specific association of HT with RA.

[Exercises in patients with myositis--active treatment intervention?]. / Vjezbe kod miozitisa--aktivna terapijska mjera?

Polymyositis, dermatomyositis and inclusion body myositis are rare inflammatory myopathies characterized by muscle weakness. Regardless of pharmacological treatment in most patients remain muscle weakness and inability to perform daily activities. Until recently, the prevailing opinion was that active exercises can exacerbate the inflammatory activity in the muscles and is now known that active exercise and exercise with resistance improve strength and endurance of muscles, aerobic capacity and overall functional ability. Exercises are prescribed according to the disease activity, manual muscle test or dynamometer measurements, range of motion, cardiorespiratory capacity and clinical status of the locomotor system. Each of the components can be influenced by targeted exercises and should be a integral part of myositis therapy.

[Radiologic imaging of crystalline arthritides]. / Radiolosko oslikavanje u kristalinicnim artritisima.

Gout is a group of diseases characterized by arthritis and is a result of urate metabolism disturbance with the deposition of monosodium urate crystals in the joint and soft tissues. Clinical manifestations include acute and chronic arthritis, tophaceous deposits, interstitial renal disease and uric acid nephrolithiasis. The diagnosis is based on the identification of uric acid crystals in joint or body fluids.

[Scoring of disease activity using BASDAI and ASDAS method in ankylosing spondylitis]. / Ocjena aktivnosti ankilozantnog spondilitisa primjenom BASDAI i ASDAS instrumenta.

Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is the most frequently used ankylosing spondylitis activity assesment by which through 6 questions 5 basic diseases symptoms (fatigue, back pain, joint pain/swelling, enthesitic points, intensity and duration of morning stiffness) are being evaluated. In distinction from mentioned, Ankylosing Spondylitis Disease Activity Score (ASDAS) is the first validated index for the AS activity assessment with the patient's assessments of the disease symptoms (back pain, duration of the morning stiffess, activity of the disease, pains and swelling of the peripheral joints) includes the acute phase reactants (SE or CRP). We compared BASDAI and ASDAS indexes to the group of patients with the AS, in order to evaluate their congruence and to evaluate the inluence of SE, fatigue and back pain at obtained values. The cross-sectional study was performed in a group of 36 patients with the AS whose disease activity levels were evaluated by the BASDAI and ASDAS (SE) index. Statistical data analysis was performed by Student t-test and frequency tables for non-parameter data. As it has been expected the significant correlation between BASDAI and ASDAS indexes has been confirmed (r=0.796; p=0.00). BASDAI/ASDAS average value of all of the patients was 4.2/2.8. From 36 patients with the AS according to the BASDAI index 42% had mild active disease (BASDAI <4), while according to ASDAS index 44% patients had very active disease (ASDAS 2.1-.5.3). Higher activity of the disease according to ASDAS index is the result of the elevated sedimentation which is assessed only in ASDAS index. Patients with higher BASDAI index statistically have more significantly expressed fatigue and spinal pain without statistically significant difference in sedimentation (p=0.120). Examinees with higher ASDAS index have also significantly more expressed fatigue and back pain, but unlike BASDAI they have sedimentation (p=0.001). ASDAS is more recent clinical indicator of the AS activities which could be compared to BASDAI instrument. In this group of patients ASDAS seems to be more sensitive index because it discriminates more patients with the active disease.

[The classification of spondyloarthritides]. / Klasifikacija spondiloartritisa.

Spondyloarthritides (SpA) are a heterogeneous group of HLA-B27 associated musculoskeletal diseases that affect the axial and peripheral skeleton and most of them have some extraskeletal manifestations. The last classification criteria for SpA that has developed ASAS (Assessment of SpondyloArthritis International Society) working group have been published recently. The new criteria include the typical clinical and laboratory characteristics of all entities from the spectrum of SpA, which enables early diagnosis and planning of treatment strategies.

[The role of magnetic resonance imaging in seronegative spondyloarthritides]. / Uloga magnetske rezonancije u seronegativnim spondiloartritisima.

Seronegative spondyloarthritides (SpA) is a group of inflammatory rheumatic diseases characterized by inflammation of the sacroiliac joints and/or the spine, enthesitis and peripheral arthritis. MRI is the imaging method of choice for visualization of the sacroiliac joint and spine according to the new ASAS classification criteria for axial SpA. It can visualize both active inflammation and structural damage and is not associated with radiation exposure. MRI findings characteristic for active disease include bone marrow edema and contrast enhancement of the bone marrow and the joint space, while chronic changes include bone erosions, sclerosis, periarticular fatty tissue accumulation, bone spurs and ankylosis. MRI has higher sensitivity comparing to other radiological modalities. MRI.is the most important diagnostic imaging method in early SpA. It is sensitive and reliable for objective monitoring of the disease process and it is essential in the management of patients with SpA.

[Benign joint hypermobility syndrome--a case report: unrecognized or undiagnosed condition?]. / Benigni hipermobilni sindrom--prikaz bolesnice: neprepoznato ili nedijagnosticirano stanje?

Hypermobility denotes an increased range of joint movements and is the result of ligamentous and joint capsule laxity. Benign joint hypermobility syndrome is hypermobility associated with symptoms--arthralgia, myalgia, fatigue, anxiety and fibromyalgia. Clinical manifestations of benign joint hypermobility syndrome include almost all organic systems, and reflect the ubiquity of connective tissue in the body. Beighton score help us to diagnoses hypermobility. Hypermobility syndrome is diagnosed using the 1998 "Brighton criteria". The purpose of this case report was to emphasize the importance of recognition hypermobility syndrome because such individuals represent a significant percentage patients who seek help of different specialist and because of the diversity of the clinical presentation very long stay unrecognized (undiagnosed). Hypermobility can be easily detected if you are looking for, but is easily overlooked if you do not think about it.

[Proposal for biologic drugs therapy in rheumatoid arthritis]. / Prijedlog primjene bioloskih lijekova u reumatoidnom artritisu.

Rheumatoid arthritis is a chronic, inflammatory disease with the prevalence about 1%. Rheumatoid arthritis is characterized with synovitis, often evolve erosions of the joints, pain and functional deficit. Etiology is unknown, but the development of such autoimmune disease is due to genetic and environmental factors. Most of the patients with diagnosis of rheumatoid arthritis use nonbiologic disease modifying antirheumatic drugs. Advances in the undersstanding of the disease process have led to the development of biological agents to treat rheumatoid arthritis. With the use of biologic agents we wish to evolve the goal of therapy from that of symptomatiic relief to clinical remission. Biologic drugs have documented, fast and continuous efficacy with generaly well accepted safety profile. On behalf of Croatian Society for Rheumatology we propose recommendations for the biologic therapy in rheumatoid arthritis.

[Guidelines of the Croatian Society for Rheumatology for the treatment of knee and hip osteoarthritis]. / Smjernice Hrvatskoga reumatoloskog drustva. Za lijecenje osteoartritisa kuka i koljena.

Osteoarthritis of the hip and the knee belongs to one of the most disabiliting conditions. Treatment goals for these patients include a reduction in pain, an improvement in joint mobility and to limit functional impairment. To properly manage osteoarthritis, both nonpharmacologic (non-interventional) and pharmacologic modalities may be employed, while minority of patients will require surgery. According to the available evidence for available therapies and experts' opinion here we present guidelines for the treatment of hip and the knee osteoarthritis in Croatia.

[Physical therapy in rheumatology]. / Fizikalna terapija u reumatologiji.

Rheumatic diseases are the leading cause of chronic disability. Physical therapy and rehabilitation are an integral part of the strategy of treatment of rheumatic diseases in order to maintain the function of the musculoskeletal system. Early detection of disability provides a more efficient implementation of all measures of physiotherapy treatment. Exercises are the most important form of physiotherapy. Long-term effect of exercise is possible only if patients achieve adherence to the program. Questionnaires activities of daily living asses functional status of patients, can be a guide for planning the rehabilitation program and indicator of the effectiveness of therapeutic intervention as well. Methods of physical therapy and rehabilitation are part of all published guidelines for the management of rheumatoid arthritis, spondyloarthritides, osteoarthritis, osteoporosis, chronic back pain, chronic non-malignant pain and fibromyalgia.

[Proposal for anti-TNFalpha therapy in adult patients with rheumatoid arthritis]. / Prijedlog primjene antagonista TNFalpha u reumatoidnom artritisu.

Rheumatoid arthritis is a chronic, inflammatory disease with the prevalence about 1%. Rheumatoid arthritis is caracterized with synovitis, erosive changes of the joints, pain and functional deficit. Etiology is unknown. In the pathogenesis of rheumatoid arthritis the key role have proinflammatory citokines, particularly, tumour necrosis factor (TNFalpha). TNFalpha blockers have documented, fast and continuous efficacy with generally well accepted safety profile. Nowdays, TNFalpha antagonists are established drugs in early and late phase of rheumatoid arthritis. Prescription of TNFalpha antagonists is controlled, according local restrictions, regarding high costs of the therapy. On behalf of Croatian Society for Rheumatology we propose recommendations for the TNFalpha antagonist therapy in rheumatoid arthritis.
