매독의 임상적, 혈청학적 양상과 치료 전후의 혈청학적 변화

초록

Background: Recently, there has been an increase in the prevalence of syphilis in Korea and in case reports of treatment failures of syphilis. Objective: This study was designed to explicate the clinical and laboratory features of syphilis, underlying diseases of the VDRL false-positive group, and responses to treatment of patients with syphilis. Methods: Between January 2001 and June 2010, we selected 115 patients with reactive results on the VDRL test. We evaluated several characteristics including their age, gender, clinical stage, skin lesion, serologic result, the rate and the underlying diseases of the VDRL false-positive group, and their serologic responses to syphilis treatment. Results: There was no significant difference in the incidence of syphilis by gender except in the case of primary syphilis. The annual incidence of syphilis has shown a significant upward trend, especially in the younger age group (10∼39 years). Using a serum VDRL titer of 8 as a cut-off value, we found a significant difference between early and latent syphilis. The rate for the VDRL false-positive group was 24.3%. Treatment failures were not reported and the median time to a successful serological response for patients with early syphilis treated with penicillin was 106days. The Jarish-Herxheimer reaction occurred in 13.7%, and these symptoms were self-limited without any treatment. Conclusion: The annual incidence of syphilis in Korea has shown a significantly upward trend, especially in the younger age group. All responses evaluated were reported for those treated successfully without having any significant adverse effects. Thus, continued surveillance and adequate treatment of syphilis is important not only to enhance disease control but also to improve public health.
