To describe the characteristics of cases of syphilis amongst prison inmates.
Descriptive study. Confirmed cases of primary, secondary and early latent syphilis were identified in prisons in Spain during 2007-2008. Socio-demographic and clinical information, as well as variables related to transmission, was collected by the attending physicians in a standard form. Frequency distributions of each variable were performed. Annual incidence rates were calculated. To evaluate the association between qualitative variables, the χ² and Fisher's exact tests were used; the Mann-Whitney test was utilized to compare quantitative variables.
During the study period, 94 syphilis cases were identified (35.1% primary, 20.2% secondary and 44.7% early latent). The incidence rates were 0.9 cases/1000 prisoners in 2007 and 0.7 cases/1000 prisoners in 2008. Most cases were male (90.4%), between 31-40 years old (30.9%) and foreigners (52.1%). The majority of patients were diagnosed through screening (80.9%). Heterosexual contact was the most frequent transmission route (83.0%). Overall HIV prevalence was 5.3%, and 16.0% of the patients had a history of previous sexually transmitted infections (STI). Almost 40% of the cases reported being a client of a sex worker.
Incidence of syphilis in prison is high. Many syphilis patients were detected through screening, highlighting the role of the Spanish prison health service in STI control.
描述监狱服刑人员梅毒病例的特征。
描述性研究。确定了2007 - 2008年西班牙监狱中确诊的一期、二期和早期潜伏梅毒病例。主治医生以标准表格收集社会人口统计学和临床信息以及与传播相关的变量。对每个变量进行频率分布分析。计算年发病率。为评估定性变量之间的关联，使用了χ²检验和费舍尔精确检验；使用曼 - 惠特尼检验比较定量变量。
在研究期间，共确定了94例梅毒病例（一期占35.1%，二期占20.2%，早期潜伏占44.7%）。2007年发病率为0.9例/1000名囚犯，2008年为0.7例/1000名囚犯。大多数病例为男性（90.4%），年龄在31 - 40岁之间（30.9%），且为外国人（52.1%）。大多数患者通过筛查确诊（80.9%）。异性接触是最常见的传播途径（83.0%）。总体艾滋病毒感染率为5.3%，16.0%的患者有既往性传播感染史。近40%的病例报告曾是性工作者的客户。
监狱中梅毒发病率很高。许多梅毒患者通过筛查被发现，凸显了西班牙监狱卫生服务在性传播感染控制中的作用。
