Objectives:
We aimed to investigate the status of oxidant and antioxidants during attack period (AP) and attack free periods (AFP) in Familial Mediterranean fever (FMF) patients.
Methods:
Measured the levels of malondialdehyde (MDA), protein carbonyl (PC), glutathione (GSH) and antioxidant vitamins (A,C and E) as well as the activities of catalase (CAT) and glutathione peroxidase (GSH-Px) in serum and whole blood of FMF patients in FMF-AP and FMF-AFP.
Results:
Levels of MDA and PC were found significantly higher (p <0.05) both in serum and whole blood of FMF-AP group compared with other groups. The CAT and GSH-Px activities in FMF-AP group were found markedly lower (p <0.05) comparing to HC group. However, there were no statistically significant differences between the groups in terms of antioxidant vitamin levels.
Conclusions:
Our study demonstrated increased oxidative stress in patients with FMF during AP. Investigations are needed to establish the effect of antioxidant supplementation on FMF attack frequency and severity. We also suggest that these increased MDA and PC levels and decreased antioxidants may be used as supportive markers to differentiate AP from AFP. These conclusions need to be validated in further multicenter studies with high number of FMF patients.
Insights
Familial Mediterranean fever (FMF) patients exhibit increased oxidative stress during attack periods (AP), indicated by higher malondialdehyde (MDA) and protein carbonyl (PC) levels. Antioxidant enzyme activities were lower during attacks, suggesting a potential role in FMF pathogenesis.
Area of Science:
- Biochemistry
- Immunology
- Genetics
Background:
- Familial Mediterranean fever (FMF) is a genetic autoinflammatory disorder.
- Oxidative stress plays a role in various inflammatory conditions.
- Understanding oxidant-antioxidant balance in FMF is crucial for management.
Purpose of the Study:
- To investigate oxidant and antioxidant status in FMF patients during attack periods (AP) and attack-free periods (AFP).
- To assess malondialdehyde (MDA), protein carbonyl (PC), glutathione (GSH), antioxidant vitamins (A, C, E), catalase (CAT), and glutathione peroxidase (GSH-Px) levels.
Main Methods:
- Serum and whole blood samples were collected from FMF patients during AP and AFP, and from healthy controls (HC).
- Levels of MDA, PC, GSH, vitamins A, C, E, and activities of CAT and GSH-Px were measured.
Main Results:
- Significantly higher MDA and PC levels were observed in FMF patients during AP compared to AFP and HC groups.
- CAT and GSH-Px activities were significantly lower in the FMF-AP group compared to the HC group.
- No significant differences in antioxidant vitamin levels were found between the groups.
Conclusions:
- FMF patients experience increased oxidative stress during AP.
- Elevated MDA and PC, with reduced antioxidant enzyme activity, may serve as biomarkers to distinguish AP from AFP.
- Further multicenter studies are needed to validate these findings and explore antioxidant supplementation's role in FMF.
