ResumenObjetivoDescribir la capacidad y organización de los laboratorios de Cataluña (España) para el diagnóstico de infecciones de transmisión sexual. Para ello, entre noviembre de 2005 y marzo de 2006 se realizó un estudio transversal incluyendo 140 laboratorios.Resultados98 realizan alguna prueba diagnóstica, 45 reciben más de 50 muestras vaginales al mes, 42 diagnostican Chlamydia trachomatis, pero solo 6 mediante amplificación de ácidos nucleicos. Ninguno diagnostica el linfogranuloma venéreo. 80 detectan la Neisseria gonorrhoeae (n 1/4 80), 76 de ellos mediante cultivo y 63 analizan su sensibilidad antimicrobiana. En total 23, 22, 22 y 14 laboratorios reciben más de 500 peticiones al mes, respectivamente de hepatitis B, hepatitis C, VIH y sífilis. 84 disponen de pruebas no treponémicas parala sífilis y 51 disponen de pruebas treponémicas.ConclusionesLa actividad de los laboratorios cubre prácticamente todo el espectro patológico, pero es necesario introducir nuevas técnicas y mejorar la eficiencia de los circuitos de muestras.AbstractObjectiveWith the aim of describing both the capacity and organization of the laboratories in Catalonia to diagnose sexually transmitted infections, a cross-sectional study was performed between November 2005 and March 2006, which included 140 laboratories.ResultsNinety-eight laboratories performed some STI tests, 45 received more than 50 vaginal swabs per month, 42 diagnosed Chlamydia trachomatis, but only six used polymerase chain reaction techniques. None diagnosed venereal lymphogranuloma. Eighty were able to detect Neisseria gonorrhoeae, 76 by means of culture and 63 analyzed its antibiotic resistance. A total of 23, 22, 22 and 14 laboratories received more than 500 blood samples for hepatitis B, hepatitis C, HIV and syphilis, respectively. Non-treponemic and treponemic tests were available in 84 and 52 laboratories, respectively.ConclusionsIn Catalonia, most STIs can be diagnosed but new technologies need to be introduced. Moreover, the efficiency of biological sample circuits should be improved.

Information about sexually transmitted infections (STI) in Barcelona is scarce. Sexual risk behaviors and some STI have recently increased.Descriptive study of STI diagnosed at the STI Unit of Barcelona between 2001 and 2002.Some STI were more frequent among homosexual men. HIV coinfection in patients with syphilis was seen in 10/18 homosexual men and 1/10 heterosexuals (p = 0.04).There is a resurgence of some STI in Barcelona. New preventive interventions are needed, especially addressed to homosexual men.
