Sexually transmitted infections of the rectum and anus (STI-RA) mainly affect men who have sex with men (MSM). The incidence of STI-RA among them has increased in recent years.
Retrospective study in patients with diagnoses of STI-RA in an STI unit during the years 2014 and 2015. Epidemiological, clinical and microbiological data were collected.
We included 95 patients, all of whom were MSM; 88.42% were HIV+; 67.17% did not use a condom during their most recent sexual intercourse; 17.91% had had sex with sex workers and 72.22% had used drugs during sexual intercourse during the previous year. A percentage of 32.92 reported symptoms that had lasted longer than 30 days. Lymphogranuloma venereum (LGV) was diagnosed in 54.73% of the patients. All patients who presented with proctitis and perianal ulcers were diagnosed with LGV infection. All those who presented perianal ulcers without proctitis were diagnosed with syphilis.
All the patients affected by STI-RA were MSM, most of them HIV+, had engaged in high-risk sexual behaviour and had suffered prolonged symptomatology. Clinical and microbiological characteristics of STI-AR could help adjust the empiric therapy.
直肠和肛门的性传播感染（STI-RA）主要影响男男性行为者（MSM）。近年来，他们中的 STI-RA 发病率有所增加。
对 2014 年和 2015 年在性传播感染科诊断为 STI-RA 的患者进行回顾性研究。收集了流行病学、临床和微生物学数据。
我们纳入了 95 名患者，均为 MSM；88.42%的患者 HIV+；67.17%的患者在最近一次性交中未使用安全套；17.91%的患者与性工作者发生过性关系，72.22%的患者在过去一年的性行为中使用过毒品。32.92%的患者报告症状持续时间超过 30 天。54.73%的患者被诊断为淋球菌性直肠结肠炎（LGV）。所有出现直肠炎和肛周溃疡的患者均被诊断为 LGV 感染。所有出现肛周溃疡而无直肠炎的患者均被诊断为梅毒。
所有受 STI-RA 影响的患者均为 MSM，其中大多数 HIV+，有高危性行为，并伴有长期症状。STI-AR 的临床和微生物学特征有助于调整经验性治疗。
