| خلاصه مقاله | Background and Aim: Osteoarthritis (OA) is a progressive rheumatic disease and inflammation has been
implicated as an important factor in the development and progression of OA and in symptoms such as
pain. This study aimed to assess the correlation between nutrients intake and inflammatory parameters
in women with knee OA.
Methods: A total of 70 knee OA women (mean age: 52.05±6.13 years) were recruited from the
rheumatology clinic of Tabriz University of Medical Sciences. Dietary intake was evaluated using a 24-
hour recall method for 3 days (including 2 working days and 1 weekend). Serum levels of interleukine-1β
(IL-1β), matrix metalloproteinases (MMPs)-1 and -13 were assessed. Correlations between variables
were analyzed by Pearson and Spearman correlation analysis, as appropriate.
Results: The mean±SD and median (IQR) IL-1β, MMP-1, and MMP-13 were 9.83±1.57, 409 (219.0,
1049.0), and 74.0 (36.0, 173.0), respectively. Total energy and carbohydrate intake correlated
significantly with serum IL-1β (r=0.256, P=0.038 and r=0.246, P=0.047, respectively) and MMP-1 levels
(r=0.259, P=0.034 and r=0.257, P=0.036, respectively). Furthermore, PUFA intake was only correlated
significantly with IL-1β (r=0.273, P=0.026). Dietary manganese intake was significantly correlated with
serum MMP-1 (r=0.261, P=0.033) and MMP-13 (r=0.304, P=0.012) levels. Moreover, there was significant
correlation between dietary zinc and serum MMP-1 level (r=0.270, P=0.027). No significant correlation
was found between dietary protein, calcium, phosphorous, magnesium, selenium and vitamin intake with
inflammatory parameters.
Conclusion: This study suggested a potential role of nutrients in cartilage loss and disease progression in
patients with knee OA; however these findings warrant further confirmation. |
