Prevalence and risk factors of syphilis and human immunodeficiency virus co-infection at a university hospital in Brazil

Abstract INTRODUCTION The incidence of syphilis has increased since the 1970s. METHODS This was a descriptive and analytical cross-sectional study with a non-probabilistic sample. RESULTS: Of 973 patients with human immunodeficiency virus, 179 (18.4%) tested positive for both human immunodeficiency virus and syphilis, 84.8% were men, 50.9% were aged between 36 and 50 years, 47.8% with syphilis were diagnosed with human immunodeficiency virus for 10-20 years, and 40.3% received antiretroviral therapy for 10-20 years. CONCLUSIONS The prevalence of syphilis in patients with human immunodeficiency virus is higher than expected, making it urgent to adopt efficient public health measures.

摘要 引言：自20世纪70年代以来，梅毒的发病率持续攀升。
方法：本研究为描述性分析横断面研究，采用非概率抽样方法获取研究样本。
结果：在973例人类免疫缺陷病毒（human immunodeficiency virus, HIV）感染者中，共有179例（18.4%）人类免疫缺陷病毒与梅毒检测均呈阳性；其中84.8%为男性，50.9%的患者年龄介于36至50岁之间，47.8%的梅毒感染者确诊HIV感染的时长为10至20年，40.3%的患者接受抗反转录病毒治疗（antiretroviral therapy）的时长为10至20年。
结论：人类免疫缺陷病毒感染者的梅毒患病率高于预期，亟需采取高效的公共卫生措施。
