Body mass index, serum rheumatoid factor and c-reactive protein among individuals with rheumatoid arthritis in Kano Metropolis
Background: Rheumatoid arthritis (RA) is becoming a global health menace associated with joints swelling, pain, stiffness, and progressive loss of function of extremities etc. This study aimed at evaluating the Body Mass Index (BMI), Serum Rheumatoid Factor (RF) and C-Reactive Protein (CRP) among RA Patients in Kano Metropolis.
Methods: A total of 111 participants comprising 74 Rheumatoid Arthritis patients and 37 apparently healthy controls were recruited for this study. Exactly 29 were males while 44 were females aged between 25 to 75 years. Using standard techniques, BMI was calculated using the weight and height taken from the participants. Blood samples were collected for serum RF and CRP and were analysed using Enzyme linked immunosorbent assay technique. Statistical Package for Social Sciences version 21 was used for the analysis of data.
Results: Our findings reveal that, females recorded higher percentage frequency of 45 (60.8%) while males recorded a lower percentage frequency of 29(39.2%) of RA patients with the ratio of 1.55:1, the higher percentage frequencies of 35(47.3%) was observed in overweight BMI patients of between 25-29.9 kg m-2. The mean serum value of RF was significantly (p = 0.00) higher in case group (4.4 ±1.5 ng/ml) compared with the control group (2.0±1.5 ng/ml) and also the mean serum value of CRP was significantly (p = 0.00) higher in case group (13.0 ±5.0 mg/L) compared with the control group (5.5±5.0 mg/L). A significant positive correlation was established between serum RF and CRP (r = 0.48, p=0.00).
Conclusion: Our findings show increased RF and CRP in RA case group. Quantitative evaluation of immunological parameter such as RF, CRP and BMI monitoring may aid in proper management of RA patients.
