Resum
Objective: Knowledge of the epidemiology of HIV infection is key to develop programs specifically directed to poorly controlled patients. Nevertheless recent studies in that field are scant, and a better knowledge of the present state of the HIV epidemic is needed. For that purpose, cross-sectional and cohort studies are suitable, as they provide invaluable information that can serve as background to carry out more specific research. With this study we aim to know the nowadays epidemiological and clinical features of HIV infection in a large multicenter cohort. Methods: Cross-sectional study, carried out with data of the Spanish VACH Cohort of HIV infected patients. A total of 53 variables are included. Descriptive statistics are used to report the results. Bivariable statistics are used to assess variation along time on modalities of antiretroviral treatment used and causes of death. Results: A total of 30,843 patients belonging to most regions of the Spain are included. 23,682 (76.78) are male, mean and standard deviation of age of all patients is 34.03 ± 9.55 years in their first visit and 43.68 ± 10.52 years in their last visit, 12,677 (41.10) are smokers, 3,521 (11.42) have diabetes, 15,351 (49.77) acquired HIV sexually and 12.714 (41,22) parenterally, 16,057 (52.06) have hepatitis C virus serology positive, median and interquartile range of CD4 lymphocyte count are: lowest 198 (79 - 337) and last available 510 (299 - 745), Last available HIV viral load is suppressed (< 200 RNA copies per mL) in 23,485 (76.14 %). Modalities of antiretroviral treatment varies substantially along time, with integrase inhibitors combinations predominating the last years. Conclusions: Patients in the Spanish HIV VACH Cohort are predominantly middle aged men. They acquired HIV sexually or parenterally in similar proportion. Most of them are taking antiretroviral treatment and have their HIV infection properly controlled.
