Clinical trials

The main objective of this study is to compare the acute effects of drinking Jägerbombs with drinking alcohol alone during a binge-drinking episode, which involves consuming a large amount of alcohol in a short period of time to become intoxicated. Secondary objectives are to assess whether Jägerbombs produce prototypical alcohol effects, increase stimulation and rewarding effects, affect coordination, time reaction and vision, change stress-related hormone responses, and cause hangover symptoms.

Myotonic Dystrophy Type 1 (DM1) is a rare genetic neuromuscular condition that can affect multiple organs and varies widely in how it presents. DM1 is the most common form of adult-onset muscular dystrophy, with an estimated prevalence of approximately 1-5 per 10,000 people. In Spain, the condition shows notable regional differences, making it especially important to understand its characteristics within the population. The aim of this study is to support a research initiative designed to better characterise DM1. We are developing a comprehensive national registry, collecting patient-reported information, clinical data and omics data that will improve our understanding of the disease and help identify individuals who may be eligible for clinical trials.

The general objective of HYPIEND is to understand the effects of chemical substances called "endocrine disruptors" (EDCs) during the perinatal and pre-pubertal stages. EDCs co-exposure may affect the function of hormones and determine endocrine consequences in vulnerable populations. The primary objective of this clinical study is to demonstrate that a multicomponent intervention implemented in health care centres from three European countries is effective in reducing the levels of EDCs in different body fluids of pregnant women, breastfeeding and formula feeding women as well as in their infants up to 18 months of age, improving at the same time the level of HAPA constructs (psychological determinants of behaviour) and the knowledge about these chemicals at family level.

The World Health Organization (WHO) aims to eliminate viral hepatitis as a public health threat by 2030, with major reductions in hepatitis B and C incidence and mortality. However, hepatitis C virus (HCV) transmission has increased among gay, bisexual, and other men who have sex with men (GBMSM), especially those living with HIV. Practices such as chemsex, particularly involving injection drug use, have contributed to this rise. Hepatitis B virus (HBV) also remains a public health challenge due to the potential for chronic infection and severe liver damage. Hepatitis D virus (HDV), which requires HBV co-infection, further complicates clinical management. This study aims to design, implement, and evaluate an online self-sampling testing strategy to enhance pan-viral testing (HBV, HCV, HDV, HIV) and improve linkage to care among GBMSM and transgender women (TW) in Spain. The intervention will involve self-collected dried blood spot (DBS) samples for testing HBV surface antigen (HBsAg), HIV antibodies, and HCV RNA. Individuals testing positive for HBsAg will undergo further testing for HBV DNA and HDV infection. Those lacking protective levels of HBV antibodies will be referred for vaccination or revaccination. The study will also assess the number of HIV-positive individuals who acquired the infection while waiting for access to PrEP, identifying missed prevention opportunities. This non-randomized, single-arm, prospective national study will recruit adult GBMSM and TW through PrEP services, dating apps, NGOs, social media, and community outreach. Participants will complete an online risk assessment (using the HCV-MOSAIC algorithm) and receive self-sampling kits with instructions, lancets, Whatman cards, and prepaid envelopes. Results will be provided online, and those testing positive will be linked to confirmatory diagnosis and care. Outcomes include estimates of HIV, HBV, HCV, and HDV prevalence; effectiveness of linkage to care; acceptability and usability of the intervention; and validation of DBS for HBsAg detection. This study will provide critical evidence on the effectiveness of online self-sampling strategies for viral hepatitis and HIV among GBMSM and TW, supporting Spain's public health goals for prevention, early diagnosis, and linkage to care.

Tuberculosis is a chronic infectious disease that affects 10 million people, 300 in the city of Barcelona, every year. With serious consequences at public health level, it is associated with other diseases, and generated and influenced by many social and psychological factors. This study aims to stage tuberculosis disease by an integrative approach.

The purpose of this screening study is to identify and screen vulnerable population in Barcelona for active pulmonary tuberculosis
