[Epidemiological situation of post-pandemic sexually transmitted infections in Catalonia, Spain]. / Situación epidemiológica de las infecciones de transmisión sexual pospandemia en Cataluña, España.

BACKGROUND: The growing trend of STIs in recent years was altered after the outbreak of the SARS-CoV-2 pandemic. OBJECTIVES: Describe the impact of the SARS-CoV-2 pandemic on STI declarations received during the pre-pandemic to pandemic period and estimate the number of STI cases expected for the pandemic period. MATERIAL AND METHODS: Descriptive analysis of STI declarations received during the pre-pandemic (2018-2019) and pandemic (2020-2021) periods. The influence of the number of positive cases of SARS-CoV-2 with the number of positive cases of STIs during the months of the pandemic was studied using a correlation model. Using the Holt-Wilson time series model, an estimate was made of the number of STI cases expected for the pandemic period. RESULTS: The global incidence rate for all STIs in 2020 decreased by 18.3% compared to 2019. Chlamydia and syphilis presented a greater reduction in their incidence from 2019 to 2020 of 22.7% and 20.9%, respectively and 9.5% and 2.5% for gonorrhea and LGV. Estimates showed that in 2020 there would have been 44.6% more STIs than those declared. The proportions according to sex, country of birth and sexual orientation changed significantly in chlamydia and gonorrhea. CONCLUSIONS: The measures adopted for the prevention of SARS-CoV-2 infections were able to achieve an initial decrease in STI cases in 2020, however, this change was not maintained during 2021, which ended with higher incidences recorded to date.

Syphilis epidemics: a descriptive study of patients diagnosed in a tertiary hospital between 2011 and 2015. / Emergencia de la sífilis: Estudio descriptivo de pacientes diagnosticados de sífilis en un hospital de tercer nivel entre 2011 y 2015.

BACKGROUND AND OBJECTIVE: In the last decade, the incidence of syphilis has increased in our health area. Our objective is to describe the epidemiological and clinical characteristics of patients diagnosed with syphilis at our centre and their relationship with HIV. PATIENTS AND METHODS: The clinical and epidemiological variables of patients diagnosed with syphilis in a third-level hospital over a period of 4.5 years, as well as their HIV status, were analysed through a descriptive study. RESULTS: There was a significant increase in the incidence of syphilis in the period 2011-2015. We included 220 patients, 98% men (94% MSM). 62% were HIV+ and 89% came in early/infectious stages of the disease. 7% were concomitantly diagnosed with HIV. There was a high number of sexual partners and frequent use of drugs associated with sexual activity (46%). CONCLUSIONS: The incidence of syphilis has increased in our centre in the last 2 years. The most affected group is MSM, with high HIV prevalence and risk behaviours for STI acquisition.
