Background:Inflammation, decreased physical activity, hormonal disorders, and the use of glucocorticoids lead to changes in the composition of the body in rheumatoid arthritis (RA). Various combinations of decreased muscle and bone mass and increased adipose tissue have led to the release of various pathological phenotypes of the composition of the body.Objectives:To determine the frequency of pathological phenotypes of body composition in patients with RA.Methods:The study included 79 women with RA, with a median age of 60 y.o. [55; 65]. 92% of the women were postmenopausal. The median duration of the disease was 9 years [3; 11]. Basic anti-inflammatory therapy was received by 81% of patients. Methotrexate was used most often as the basic therapy – in 52% of cases. 49% of patients were treated with glucocorticoid drugs. All patients underwent dual-energy X-ray absorptiometry. The mineral density of the tissues was determined in the standard measurement areas - the spine and the proximal thigh, and the content of muscle and adipose tissue was analyzed. We calculated appendicular muscle mass (AMM), which is the sum of upper and lower limb muscle mass and appendicular muscle index (AMI), the ratio of appendicular muscle mass to the square of height. AMM< 15 kg, AMI < 6 kg / m2 corresponds to sarcopenia.Results:The average AMM was 17.8±3.0 kg. 18% patients had AMM <15 kg / m2. The average AMI was 6.8±1.0 kg / m2. 25% patients had AMI < 6 kg/m2. The average body mass index (BMI) was 27.6±4.8 kg/m2. 37% patients were overweight (25≤ BMI <29.9 kg/m2), 28% of women had a BMI corresponding to obesity. The average fat content was 28.2 kg. 71% of women had an obesity, according to X-ray absorptiometry, which is 2.5 times higher than the number of cases of obesity detected by BMI. A decrease a bone mineral density (BMD) was found in 73% of women, including osteoporosis in 25%. The most frequent phenotype was osteopenic obesity (Table 1), which was detected in almost 40% of patients. Isolated osteoporosis (16.5%) and obesity (17.7%) and osteosarcopenic obesity (16.5%) were found with approximately the same frequency. Osteosarcopenia was found in 9% of patients. In 4%, no changes in the compositional composition of the human body were detected.Table 1.Pathological phenotypes of body compositionPathological phenotypes of body compositionn=79Osteoporosis, n (%)13 (16,5)Obesity, n (%)14 (17,7)Osteosarcopenia, n (%)7 (8,9)Osteopenic obesity, n (%)29 (36,7)Osteosarcopenic obesity, n (%)13 (16,5)Conclusion:The overall frequency of pathological phenotypes of body composition was high and amounted to 96.2% in women with RA. The most common pathological phenotype was an osteopenic obesity characterized by a decrease in BMD and an increase in fat mass.Disclosure of Interests:None declared

Background:Rheumatoid arthritis (RA) is a complex inflammatory disease that modifies body composition. Using the dual-energy x-ray absorptiometry (DXA) in RA patients could be a method for body composition changes detection.Objectives:To study the body composition using DXA in patients with RA.Methods:The study involved 79 women with RA, median age 60 [55; 65] years. The bone mineral density (BMD) was measured by dual-energy x-ray absorptiometry using «Discovery A» (Hologic, USA). Assessment of body composition was carried out, using the program «Whole body». Sarcopenia (SP) was diagnosed as a decrease in appendicular mass index (AMI) <6.0 kg/m2. Osteoporosis (OP) was diagnosed as a decrease in T-score <-2.5 SD. Osteosarcopenia was determined when T-score was <-1.0 SD, AMI was <6.0 kg/m2, osteosarcopenic obesity - T-score was <-1.0 SD, AMI was <6.0 kg/m2and total fat was >35%.Results:The mean duration of RA was 9 [3; 11] years. The mean body mass index (BMI) was 27.6±4.8 kg/m2. Disease activity score in 28 joints-erythrocyte sedimentation rate was 4.5±1.3 points for the group. 39 (49.3%) patients used oral glucocorticoids continuously. Appendicular muscle mass and AMI were on average 17.8±3.0 kg and 6.8±1.0 kg/m2, respectively. AMI <6 kg/m2was detected in 20 (25.3%) patients. 56 (70.9%) women with RA had total fat > 35%, while only 22 (27.8%) of women with RA had obesity according to BMI (BMI >30 kg/m2). Isolated OP was found in 13 (16.5%), osteosarcopenia in 7 (8.9%) and osteosarcopenic obesity in 13 (16.5%) patients RA. No cases with isolated sarcopenia or sarcopenic obesity were detected. Only 3 (3.8%) patients did not have appendicular muscle mass, AMI and BMD decrease and overfat or obesity.Conclusion:About 97% women with RA had abnormal body composition phenotype: 16,5% - OP, 8.9% -osteosarcopenia, 16,5% - osteosarcopenic obesity and 54,4% - overfat.Disclosure of Interests:None declared

Abstract Aim. Rheumatoid arthritis (RA) may influence not only abdominal fat, but also whole body adiposity, since it is associated with chronic inflammation and disability. The study aims to evaluate the whole body adiposity of RA patients and to assess potential influences of disease specific measures. Methods. The study was designed to include Caucasian postmenopausal female RA patients and age-matched postmenopausal female controls. Each subject underwent on the same day clinical examination, laboratory tests, whole body dual X-ray absorptiometry (DXA) composition and physical activity estimation using a self-administered questionnaire. Results. A total of 107 RA women and 104 matched controls were included. Compared to controls, the RA group had less physical activity and a higher prevalence of normal weight obesity. Overfat RA women had a significantly higher toll of inflammation, disease activity, glucocorticoid treatment and sedentary behavior. RA women with inflammation, glucocorticoid treatment and higher disease activity class had higher whole body and trunk adipose tissue indices and higher prevalence of overfat status. Glucocorticoid treatment, inflammation, disease duration and severity correlated with whole body adipose tissue and significantly predicted high adiposity content and overfat phenotypes. Conclusions. RA disease duration and severity are associated with higher whole body and regional adiposity. Low-dose glucocorticoid treatment seems to contribute to adiposity gain and redistribution. Clinicians may need to assess body composition and physical activity in RA patients in order to fully manage cardiovascular outcomes and quality of life.

Few Data

Rheumatoid arthritis (RA) is associated with a decrease in lean mass and stability or even an increase in fat and ectopic adipose tissue. A few data are available on body composition changes under treatment, and data are still controversial. Body composition was assessed before initiation of biologic disease-modifying antirheumatic drug (bDMARD) and after 6 and 12 months of stable treatment. Eighty-three RA patients were included (75% of women, mean age 58.5 ± 10.8 years) of whom 47 patients treated with TNF inhibitor (TNFi), 18 with non-TNF-targeted biologic (Non-TNFi), and 18 with conventional DMARD (cDMARD) alone. In the TNFi group, total lean mass, fat-free mass index, and skeletal muscle mass index significantly increased at 1 year. An increase in subcutaneous adipose tissue (SAT) without change for the visceral or body fat composition was associated. These changes were associated with an improvement in strength and walking test. In non-TNFi or cDMARD groups, no significant changes for body composition or muscle function were observed at 1 year. However, no significant differences for treatment x time interaction were noted between group treatments. In active RA patients starting first bDMARD, treatment with TNFi over 1 year was associated with favorable changes of the body composition and muscle function.

Abstract. In the context of future growth and performance testing, this study compares corresponding body composition results measured by two dual energy X-ray absorptiometry systems. To test the capability of each device to detect differences among experimental groups widely varying in body composition, 77 pigs from 6 purebred/crossbred groups were used for the experiment. Each pig was scanned consecutively on a Norland XR-26 and on a GE Lunar DPX-IQ. Coefficients of determination were: R²=0.92 for bone mineral content (BMC), R²=0.90 for bone mineral density (BMD), R²=0.94 for lean mass (LEAN), R²=0.92 for fat mass (FAT), R²=0.88 for lean percentage (%LEAN) and fat percentage (%FAT). However, Norland yielded larger values for %FAT and smaller values for %LEAN, BMC, and BMD than Lunar (P<0.001) with the extent of deviation depending on the specific trait and on the breeding group. The deviation in BMC was greater than the deviation in BMD, suggesting different bone detecting algorithms. Both systems revealed similar differences among the breeding groups, and ranked them in the same order based on numerical values. Differences in calibration, bone detection, and software algorithms, however, require a prior crosscalibration to make the body composition data from both systems directly comparable. Finally, they can be used across research centres for the determination of relative and absolute body composition differences among animal groups and individuals.

Objective: to assess bone mineral density (BMD) and the incidence of osteoporosis (OP) and sarcopenia (SP) in women suffering from rheumatoid arthritis (RA).Patients and methods. Eighty-one women (mean age, 59.0±8.1 years) with a reliable diagnosis of RA were examined. The women underwent the following studies: a survey using a special questionnaire; tests to measure the functional status of muscles, including those to determine their strength; as well as dual-energy X-ray absorptiometry of the axial skeleton and whole body.Results and discussion. According to the EWGSOP2 criteria, 20 (24.7%) female patients were diagnosed with SP, 24 (29.6%) had OP, and 39 (48.2%) had osteopenia. OP in female patients with and without SP occurred in 35.0 and 27.9% of cases, respectively (p>0.05). BMD in the femoral neck and in the proximal femur as a whole was significantly lower in the presence of SP than in its absence (p=0.0006 and p=0.0061, respectively). The frequency of falls was significantly higher in the female patients with SP than in those without SP (p=0.028). The major osteoporotic and hip fracture probabilities calculated according to the FRAX ® algorithm was higher in the patients with SP than in those without SP (p=0.041 and p=0.033, respectively). There were positive correlations of BMD with body mass index, appendicular muscle mass, appendicular muscle index, hand strength, shoulder circumference, and the serum levels of calcium, creatinine and uric acid, as well as negative correlations with age, postmenopausal length, and RA duration.Conclusion. OP and SP are common RA complications that increase the risk of falls and fractures.

ObjectiveOsteosarcopenic obesity (OSO) may be associated with an increased prevalence of hypertension. The aim of this study was to examine the difference in the prevalence of OSO and hypertension among four minority populations in China and explore the relationship between OSO and hypertension by sex.DesignThis study adopted a cross-sectional design.ParticipantsIn total, 1939 participants aged ≥50 years, including 459 Jing, 514 Maonan, 535 Hmong and 431 Yao participants from Guangxi Province, China, were included using stratified cluster random sampling.Main outcome measuresThe body composition, bone mineral density and blood pressure were measured by an MC-180 body composition analyser, Achilles Express ultrasound bone densitometer and OMRON HEM-1000 electronic sphygmomanometer, respectively.ResultsThe results showed that 65.77% of Hmong men, 58.79% of Hmong women, 54.82% of Maonan men, 50.00% of Maonan women, 41.92% of Jing men, 45.21% of Jing women, 53.66% of Yao men and 42.32% of Yao women suffered from hypertension. Compared with those among the normal group, the adjusted OR and 95% CI of age among the women with OSO was 3.15 (1.13 to 8.78). After adjusting for age, ethnicity, smoking status, alcohol consumption, physical activity and menopausal status, the women with OSO also had a higher OR (OR=3.18, 95% CI 1.14 to 8.88) for hypertension than those in the normal group. However, the ORs (95% CI) for hypertension in men with one or more components were not significant after adjusting for age and ethnicity.ConclusionThese results suggest that OSO is a risk factor for hypertension, especially in women. Furthermore, the prevalence of OSO and hypertension in the present study displayed sex-specific and ethnic-specific differences among the four minority populations.

Aim of the study was to clarify the body composition in patients with early rheumatoid arthritis before starting therapy with synthetic basic anti-inflammatory drugs, genetically engineered biological drugs and glucocorticoids using dual-energy X-ray absorptiometry and to assess the effect of inflammation and metabolic syndrome on body composition.Material and methods. The study included 37 patients (31 women and 6 men) with early rheumatoid arthritis. The control group consisted of 19 healthy donors without rheumatic diseases. Patients with rheumatoid arthritis and the control group were measured by waist size, height and weight, and body mass index was calculated. Body composition was determined by means of dual-energy X-ray absorptiometry using the “Whole Body” program on the HOLOGIC device (USA). The presence of metabolic syndrome was assessed according to the criteria of the International Diabetes Federation (IDF).Results. Patients with early rheumatoid arthritis had less lean tissue mass, which was negatively correlated with inflammatory markers (ESR and C-reactive protein levels). Overweight and obesity were diagnosed in 24% and 27% of patients with early rheumatoid arthritis, respectively. Patients with rheumatoid arthritis and metabolic syndrome had a higher body weight, body mass index, waist size, and adipose tissue mass than patients without metabolic syndrome. With the help of instrumental methods, it is shown that in rheumatoid arthritis there is a redistribution of fat mass in the body, its predominant accumulation in the trunk area and a parallel decrease in the volume of muscle tissue.Conclusion. Rheumatoid inflammation and metabolic syndrome affect body composition of patients with early rheumatoid arthritis before the start of antirheumatic therapy.

Background: Body composition plays a fundamental role in the occurrence of complications in rheumatoid arthritis. Authors conducted this study, which aimed to determine body composition and its effects on physiological status in African sub-Saharan polyarthritis women.Methods: The anthropometric parameters were measured after an interview and a complete physical examination. The body composition was evaluated using a Tanita® brand bioimpedance meter. Finally, all the patients had a dosage of certain biochemical parameters.Results: An excess of percent fat mass was noted in more than half of women (59.52%) without loss of muscle mass. At the same time, 30% of women had a significant decrease in the percentage of body water. The BMI did not appear to be an adequate proxy for these changes. Visceral fat level was elevated just in 16% of women, however it would be a determinant of physiological aging of subjects. Dual therapy methotrexate and corticosteroid would have varying effects depending on the duration and the dose of treatment. The basic metabolism in polyarthritic subjects would be dependent on two parameters namely muscle mass and inflammatory state.Conclusions: Evaluating changes in body composition quickly, non-invasively and inexpensively is possible. It could be useful in the follow-up of rheumatoid arthritis. Managing these changes can reduce cardiovascular morbidity and mortality in rheumatoid arthritis.

Objective. To study the bone mineral density (BMD) and appendicular muscle mass (AMM), their interrelation and relationship with calcium intake and vitamin D level in women with rheumatoid arthritis (RA).Material and methods. 43 women (mean age 57.5 ± 7.0 years) with confirmed RA were included. All patients were interviewed using a special questionnaire. Dual-energy X-ray absorptiometry (DXA) of lumbar spine, hip and total body was performed, and dietary calcium intake and vitamin D blood serum levels were assessed.Results. Reduced BMD was detected in 76.8% of patients, including osteoporosis (OP) – in 23.3%, and osteopenia – in 53.5% of women. Low AMM was found in 11.6%, and reduced appendicular muscle index (AMI) was found in 18.6% of the examined patients. Women with low BMD had significantly lower AMM and AMI scores than patients with normal BMD. The average calcium intake was 737 mg per day, while it was lower in patients with OP compared to those with normal BMD (p = 0.038). Among all women, 56% of individuals needed additional calcium supplementation. The average level of vitamin D in the blood serum was 20.8 ng/ml, with the incidence of insufficiency – 48.8%, and deficiency – 41.9% without significant differences between individuals with OP, osteopenia and normal BMD.Conclusion. In women with RA, reduced BMD was found in 76.8%, reduced AMM – in 11.6%, and low AMI – in 18.6% of cases. Patients with low BMD had lower AMM and AMI than women with normal BMD. Calcium intake was significantly lower in patients with OP compared to those with normal BMD.
