简要总结
Ankylosing Spondylitis (AS) is a chronic inflammatory autoimmune disease. The aim of this study is to reveal the relationship between dietary intake, blood total antioxidant capacity and disease activity in individuals with AS. This study will include patients diagnosed with AS who applied to Ankara City Hospital Physical Therapy and Rehabilitation Hospital, and a control group that does not have AS. The sociodemographic characteristics and nutritional habits and 1-day physical activity status of individuals with AS and healthy persons will be recorded. Anthropometric measurements of all individuals (such as height length (cm) and body weight) will be taken. From the height and body weight measurements, the individuals body mass indexes will be calculated. All parts of the questionnaire for individuals included in the research will be filled in by the researcher through face-to-face interview technique. The disease activity score of the individuals in the case group will be evaluated by the physician. Serum biochemical parameters will be taken from the patient files. In the patient information system of the control group, above mentioned blood tests will be recorded from the examinations performed in the last 1 month. Serum total antioxidant and oxidant levels will be measured in a private laboratory with a tube (5 ml) of blood from all individuals. The parameters to be examined in blood samples are specific to the study and their cost will be covered by the researchers.
详细描述
Ankylosing Spondylitis (AS) is a chronic inflammatory autoimmune disease that progresses with inflammation of synovial membranes. The aim of this study is to reveal the relationship between total dietary phytochemical intake, blood total antioxidant capacity and disease activity in individuals with AS. This study will include patients diagnosed with AS who applied to Ankara City Hospital Physical Medicine and Rehabilitation Hospital, and a control group that does not have AS and that meet exclusion criteria. The sociodemographic characteristics and nutritional habits, one-day food consumption records and 1-day physical activity status of AS diagnosed and healthy individuals included in the study will be recorded with a questionnaire. Anthropometric measurements of all individuals (case and control) such as height length (cm) and body weight (kg) will be taken. From the height and body weight measurements, the students' body mass indexes will be calculated from the formula [weight (kg) / height (m²)]. Waist circumference; The perimeter passing through the middle of the distance between the lowest costa and crista iliaca superior will be measured by tape measure. All parts of the questionnaire for individuals included in the research will be filled in by the researcher through face-to-face interview technique. The disease activity score (ASDAS) of the individuals in the case group will be evaluated by the physician. Serum biochemical parameters (complete blood count, fasting blood sugar, liver function tests, urea, creatinine, lipid profile, erythrocyte sedimentation rate, c-reactive protein) will be taken from the patient files. In the patient information system of the control group, complete blood count, fasting blood sugar, liver function tests, urea, creatinine, lipid profile, erythrocyte sedimentation rate, and c-reactive protein levels will be recorded from the examinations performed in the last 1 month. Serum total antioxidant and oxidant levels will be measured in a private laboratory with a tube (5 ml) of blood from all individuals. After the blood samples are centrifuged, 0.5 ml will be separated into eppendorfs. Samples will be stored in a -80 degree refrigerator in the Physical Medicine and Rehabilitation Hospital. Total antioxidant and oxidant capacity measurement will be done in a private laboratory in Ankara in the form of service procurement by Erel method. Samples for total antioxidant and oxidant analysis will be sent to the relevant laboratories in dry ice. The parameters to be examined in blood samples are specific to the study and their cost will be covered by the researchers.

结局指标
主要结局
Total antioxidant and oxidant capacity
时间窗: Blood samples will be obtained once on the first day after inclusion. Samples will be stored in -80 C medical refrigerator and analysis will be done after collection of all samples.
Higher total antioxidant capacity and lower oxidant capacity is better.
Ankylosing Spondylitis Disease Activity Score
时间窗: Will be done only once on the first day after inclusion.
Higher scores (\>2.1) mean active disease. Lower scores (\<1.3) mean inactive disease
Dietary phytochemical index
时间窗: Will be done only once on the first day after inclusion.
Dietary phytochemical index is calculated from one day dietary record. Higher index is better.
