Proctitis infecciosa transmitida sexualmente: reto diagnóstico y recomendaciones de tratamiento

Sexually transmitted infectious proctitis is an inflammatory process of the rectum secondary to infection by sexually transmitted germs. Neisseria gonorrhoeae, Chlamydia trachomatis, Treponema pallidum, and herpes simplex virus (HSV) are the most frequently pathogens. Infectious proctitis is more prevalent in men who have sex with men (MSM) and in patients with human immunodeficiency virus (HIV) infection, however, it is also diagnosed in heterosexuals by changes in sexual behavior. Fecal urgency, purulent or bloody exudate, proctalgia, and tenesmus are the most common clinical manifestations. Detailed clinical history and a high index of suspicion are important to establish the diagnosis of this pathology; supported by endoscopic, histological, serological, and microbiological studies. Empirical treatment with antibiotics or antivirals is recommended, depending on clinical suspicion, and other sexually transmitted infections (STIs) should always be ruled out.
