Introduction and Objective: 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., Material and Methods: 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., Results: 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., Conclusions: 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., (Copyright © 2018 Elsevier España, S.L.U. All rights reserved.)

Background: There are very few data available regarding risk factors associated with antibiotic resistant-Neisseria gonorrhoeae., Methods: A study was conducted on 110 samples from 101 patients with gonococcal infection, in order to describe their characteristics and compare them with the antimicrobial susceptibility profile of their samples., Results: An association was observed between resistant infections and heterosexual men, older age, concurrent sexually transmitted infection, and unsafe sexual behaviors., Conclusion: There is a need for improved data on the risk factors associated with antibiotic resistant gonococcal infection in order to identify risk groups, and to propose public health strategies to control this infection., (Copyright © 2016 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.
