Papel de la detección regular de sustancias en orina en pacientes en valoración pre-transplante hepático por hepatopatía alcohólica

Alcohol Liver Disease (ALD) is one of the most prevalent conditions leading to liver transplantation for end-stage liver disease. There is lacking evidence of regular urine screening testing (RUST) impact on survival or liver transplantation of ALD patients. The aims of this study were to compare the sensitivity of RUST, to assess its impact on survival and liver transplantation, and to evaluate factors associated with adherence to RUST. We performed a single-centered retrospective study (N = 84) with ALD candidates for liver transplantation. Demographic, biochemical and clinical variables were recorded at baseline. Adherence to RUST was evaluated during follow-up. The sensitivity of both RUST and self-reports were calculated for all drugs. Multivariable logistic and survival regression analyses were performed to explore associated factors and the impact of adherence to RUST, and positive results on survival. RUST had high sensitivity for identifying active drinkers (76.9%), smokers (78.9%) and cannabis users (83.3%). High adherence to RUST was inversely associated with mortality during follow-up. Presence of personality disorders negatively impacted (OR 0.29, CI 95% 0.08-0.97) adherence to RUST. Both RUST and self-reports should be carried out in this setting. Professionals involved in liver transplantation programs must promote adherence to RUST, primarily in patients with personality disorders.
