Özet

Objective: This study aimed to examine patients with lead poisoning in terms of metabolomic profiles and bioactive lipids (oxysterols and sphingosine 1-phosphate [S1P]) before and after chelation therapy. Methods: Consent was obtained from 42 individuals diagnosed with lead poisoning and blood and urine samples were collected before and after chelation therapy. The levels of 7-ketocholesterol (7-KC), cholestan-3b,5a,6b-triol (Ctriol), and S1P were measured via LC-MS/MS. Metabolomic analysis was performed via GC-MS. Results: 7-KC and C-triol levels were detected higher before chelation therapy compared with after therapy (P < 0.001 for both). S1P levels were measured higher before the therapy. The results also showed that sphingolipid metabolism-related pathways were affected by lead toxicity as well as other related pathways. Conclusion: This preliminary study showed that lipid metabolism is affected in lead exposure and chelation therapy is effective in reversing possible damage.
