This study compares workability in subjects with seropositive rheumatoid arthritis (RA) in the working age with high and low disease activity. Further interest is to clarify the influence of frailty, functional ability and muscle strength on workability and to determine the effect of disease activity on selected physiological needs (sleep quality, sexual functioning). Methods include a physical examination, questionnaires and physical tests.

Other | IL-6 | IL-6 levels will be measured in the blood. Standard venous blood sampling. | Day1 | |
Other | TNF-alpha | TNF-alpha levels will be measured in the blood. Standard venous blood sampling. | Day1 | |
Other | CRP | CRP-alpha levels will be measured in the blood. Standard venous blood sampling. | Day 1 | |
Primary | Workability | Self-reported work ability will be measured by the work ability index (WAI). The WAI is a questionnaire consisting of seven subscales: current work ability compared with the lifetime best; work ability in relation to the demands of the job; number of current diseases diagnosed by a physician; estimated work impairment due to disease; sick leave during the past 12 month; own prognosis of work ability 2 years from now; and mental resources. The cumulative index of WAI ranges from 7 to 49 points. It is then divided into 4 categories: poor (7-27 points), moderate (28-36 points), good (37-43 points) and excellent work ability (44-49 points). | Day 1 | |
Secondary | Functional Disability | Extend of the patients´ self-reported functional disability will be assessed by the Health Assessment Questionnaire Disability Index (HAQ -DI). There are 20 questions in eight categories of functioning - dressing, rising, eating, walking, hygiene, reach, grip, and usual activities. Self-reported difficulties to perform these activities are scored on a scale from 0 to 3, representing normal (no difficulty) (0), some difficulty (1), much difficulty (2), and unable to do (3). For any component question, highest score determines the score for that respective domain. The overall disability index is a value between 0 ( no functional disability) and 3 (severe functional disability) representing the average score across the domains. | Day 1 | |
Secondary | Frailty | Frailty will be assessed with the SHARE Frailty Instrument (SHARE- FI).The assessment comprises 5 variables: grip strength measurement and 4 questions related to weakness, exhaustion, slowness and the activity level. Using the 5 variables DFactor scores (DFS) will be calculated using the gender specific SHARE-FI formula. For each subject the frailty score will be computed and subjects will then be categorized as non-frail, pre-frail, or frail. | Day 1 | |
Secondary | Lower-extremity function | Lower-extremity function will be measured with the short physical performance battery (SPPB). The SPPB is a group of measures including gait speed, chair stand and balance tests. Each test a five-level categorical score will be assessed, with 0 representing inability to complete the test and 4 representing the highest level of performance. The summary score ranges from 0 (worst performance) to 12 (best performance). | Day 1 | |
Secondary | Musculus quadriceps femoris strength | Quadriceps muscle strength will be measured with an isokinetic dynamometer.Strength will be assessed 3 times for both legs with a 2 minute break between the measurements. Per software analysis maximum peak value of every leg will be determined on the basis of power vs. time curve. Mean value of both legs will be used in the statistical analysis. | Day1 | |
Secondary | Hand grip strength | Maximum grip strength will be measured with a portable hydraulic hand dynamometer. Three maximum voluntary grip strength contractions will be taken for each hand. Measurements will be done in alternating order with a 2 minutes break between each measurement. The mean value of each hand will be taken for analysis. | Day1 | |
Secondary | Quality of sleep | The patients´ quality of sleep will be assessed with the MOS Sleep Scale (MOS -SS) questionnaire.The MOS-SS is a 12-item self -report questionnaire referring to a retrospective assessment over the past 4 weeks. The MOS measures 6 sleep dimensions: Initiation (time to fall asleep in minutes), quantity (hours of sleep each night), maintenance, respiratory problems, perceived adequacy and somnolence. The last 4 items will be assessed via a 6-item scale ranging from "all the time" to "none of the time". The questionnaire yields 2 sleep problem indexes and 6 scores. | Day1 | |
Secondary | Sexual functioning | Sexual functioning will be measured via self-assessment questionnaire individually designed for this study.The questionnaire consists of two sections addressing sexual disability (difficulties in performing sexual intercourse) represented by question 1 and sexual drive ( reflected in sexual desire and satisfaction) represented by question 2-5. Scoring ranges from 1-10 and anchor points are set according to the question. Overall sexual functioning score ranges from 5 points (poor sexual functioning) to max 50 points. | Day1 |
