HURTADO, Isabel et al. Increased syphilis trend among patients in an AIDS information and prevention center. Gac Sanit [online]. 2011, vol.25, n.5, pp.368-371. ISSN 0213-9111.

Objective: A rebound of syphilis cases has recently been observed. This study describes the trend in syphilis infection among persons attending the AIDS information and prevention center of Valencia, Spain. Methods: We performed a cohort study of all persons attended from 2000 to 2006. The calendar effect was assessed by a logistic regression model adjusted by sexual and sociodemographic variables. Results: A total of 71% were heterosexuals (HT) and 19% were men who had sex with men (MSM). Among the 10,850 users of the center, the prevalence of syphilis was 0.7%. Among MSM, the prevalence of syphilis was 2.4% for the whole period and was 4.6% for 2006. Multivariate analysis showed that the risk of infection was lower in persons with a university education (OR=0.10; 95%CI: 0.03-0.59) than in those without. The risk was higher in persons who took drugs (OR=5.49; 95%CI: 1.55-19.43) or who practiced prostitution (OR=6.83; 95%CI: 2.52-18.53). In 2006, the risk of having syphilis was greater (OR=5.05; 95%CI: 1.12-22.72). Conclusions: Syphilis infection increased substantially among MSM. In this collective, the prevalence of infection is related to educational level, prostitution and the use of non-injected recreational drugs.
