The pathogenesis of syphilis is not completely clear. Oxidative stress can play a certain role. Antibodies to oxidized low-density lipoproteins (anti-oxLDL) reflect the level of oxidative stress.
To study the production patterns of antibodies to anti-oxLDL in syphilis, their clinical and laboratory associations, and changes during syphilis therapy.
The anti-oxLDL level was measured in 154 patients with various forms of syphilis, of which 57 patients were followed-up. IMTEC-oxLDL-Antibodies Ig(GM) ELISA kits were used to detect anti-oxLDL.
Patients with secondary syphilis had the highest levels of anti-oxLDL compared to those with other types. Overall, anti-oxLDL was significantly higher in early syphilis versus untreated late syphilis and untreated late syphilis versus seroresistant patients. In late syphilis, patients with symptoms had higher levels of anti-oxLDL than those without in laboratory-confirmed neurosyphilis. In a multivariate model, the rate of clinical manifestations consistent with neurosyphilis was increased with increased anti-oxLDL level (by 3.8 times), cerebrospinal fluid abnormalities (8.1 times), and no history of syphilis therapy (4.9 times). A higher anti-oxLDL level is associated with a higher titer of microprecipitation test in early syphilis, while in late syphilis, such a relationship was not observed. The level of anti-oxLDL decreased shortly after the start of therapy in patients with early syphilis, and in patients with late syphilis, it decreased slowly and persisted for years.
Oxidatively modified LDLs play a significant role in syphilis pathogenesis and the occurrence of complications. Anti-oxLDL can be considered a potential biomarker for assessing immediate treatment outcomes for early syphilis.
