The association between body mass index, diagnostic markers and disease activity score with progression of rheumatoid arthritis in a sample of Iraqi patients

Abstract

Background: Rheumatoid arthritis (RA) is a widespread, chronic, systemically inflammatory disease which, if improperly treated, can cause deformed joints and functional disability. For best disease management, greater chances of recovery, and the avoidance of irreversible clinical and radiographic damage, RA must be diagnosed and treated as soon as possible.Objectives: The purpose of this study was to evaluate body mass index utilizing DAS and levels of diagnostic tests in rheumatoid arthritis patients.Materials and methods: 120 patients with rheumatoid arthritis (60 newly diagnosed untreated patients and 60 others under treatment) were collected from Al-Yarmouk Hospital in Baghdad and 60 control individuals. Body mass index (BMI) was measured by equation and diagnostic tests, then vitamin D3 with the COPAS 111 device. Results: The prevalence of the disease in females was 91%, while males were 9%. Diagnostic tests recorded clear significance (p < 0.05) differences between patients and healthy persons, and it increased with the severity of the disease. Additionally, patients' levels of vitamin D3 reduced significantly when compared to controls, and there was a significant disparity between patients and healthy participants' sugar levels, and the BMI correlated with disease activity.Conclusions: The current study concluded that there is a relationship between weight gain and disease severity, that diagnostic tests increased in patients, and that vitamin D3 can be used as a diagnostic marker for rheumatoid arthritis.
