RESUMO
BACKGROUND: The harmful effect of alcohol on the immune system may be due to both a direct action of the alcohol or its metabolites on immune cells as an indirect action modifying the different mechanisms of intercellular interaction. The interplay between stimulatory (aKIR) and inhibitory (iKIR) natural killer (NK) cell receptors and their corresponding human leukocyte antigen (HLA) ligands influences the outcome of virus infection. The aim was to analyze the influence of the KIR/HLA pair genetic profile in male alcoholic cirrhosis (AC) patients with and without viral infections to find susceptibility biomarkers that can help establish the risks and prevent viral infections. METHODS: A total of 281 male AC patients were analyzed. The sociodemographic characteristics, viral hepatitis C (HCV), hepatitis B (HBV), and cytomegalovirus (CMV) infections were analyzed. Genomic DNA was extracted, and genetic the KIR/HLA profiles were investigated. A total of 6 KIR genes and their corresponding ligands (HLA-C) were analyzed. Patients were grouped into two groups: with and without associated viral infection. RESULTS: A statistically significant increase in the combination of KIR2DL2+/C1C1 was observed in male AC patients with viral infection compared to those without viral infection (45.9% vs. 24.5%, p = 0.021). The analysis of KIR2DL3+/C1+ showed a high frequency comparing healthy controls and male AC patients without virus infection (85% vs. 76.4%; p = 0.026). The analysis of KIR2DL3+/C2C2 frequency showed a statistically significant increase comparing male AC patients without viral infection and healthy controls (23.6% vs. 15%; p = 0.026). CONCLUSIONS: The genetic KIR2DL2+/C2C2 profiles may play a significant role in determining the vulnerability of male AC patients to viral infections, providing valuable insights for future research and potential therapeutic interventions.
RESUMO
OBJECTIVES: The aim of this study was to analyze alcoholic cirrhosis in women who were to undergo liver transplant, including their biochemical and clinical characteristics, main complications, survival rates, and main causes of death compared with men with alcoholic cirrhosis. MATERIALS AND METHODS: Our study included 400 patients with alcoholic cirrhosis, which we divided according to sex and viral infections. Biochemical parameters and the presence and degree of ascites and encephalopathy, liver function status, and liver rejection and survival rates were analyzed from 1 to 10 years and the main cause of death at 10 years. RESULTS: Patients with nonviral alcoholic cirrhosis and liver transplant had significantly better survival rates (84.1%) at 1 year versus those with viral alcoholic cirrhosis (74.5%; P = .036). Men with nonviral alcoholic cirrhosis (14%) and women with hepatitis C virus (29%) had the lowest short-term survival rates. In long-term survival analysis, the lowest rate was observed in women with nonviral alcoholic cirrhosis (26.1%), and the highest rate was observed in women with hepatitis C virus (42.9%). Liver graft failure was one of the main causes of death in male patients (19.5%). CONCLUSIONS: Women with alcoholic cirrhosis showed a higher rate of ascites and encephalopathy but lower liver graft rejection than men with alcoholic cirrhosis. Survival rates were similar between men and women, although slightly lower in women who had hepatitis C virus.

BACKGROUND: Alcoholic cirrhosis (AC) is a common cause of death among individuals abusing alcohol. In the last resort, liver transplantation (LT) is considered the only solution to save the patient's life, generating socioeconomic and public health problems. Clinical and sociodemographic characteristics, rejection frequency, and short- and long-term graft survival are not well known in end-term AC patients undergoing LT. The aim was to determine the sociodemographic and clinical characteristics, their incidence in LT, main pre- and posttransplant complications, and short- and long-term post-transplant graft survival in AC patients in southeastern Spain. METHODS: The medical records of 1,026 patients who underwent LT over the last 23 years were retrospectively reviewed, and demographic data and posttransplant survivals were analyzed and compared. Biochemical characteristics, major pre- and posttransplant complications and short- and long-term survivals were analyzed in a total of 398 male patients with AC undergoing LT. RESULTS: AC and viral cirrhosis are the main indications for LT in our study. Mostly represented in our study are AC men without associated viral infections with a mean age of 53.06 years. Main pretransplant complications in AC patients are ascites (78.3%) and encephalopathy (43.5%), while acute graft rejection is the most common liver posttransplant complication (26.6%), nevertheless with low graft loss frequency (1.1%). AC and autoimmune cirrhosis show the best posttransplant survival in both the short and long term. Patients with AC included on the waiting list for LT were Child-Pugh class B (52.1%) and Model for End-Stage Liver Disease score of 10 to 19 (71.2%). The highest percentage of AC patient survival was observed at 1 year posttransplant (81.2%) and progressively decreased over time up to 10 years posttransplant (69.6%). Pretransplant complications such as ascites and encephalopathy did not have an influence on the percentage of posttransplant survivals, although better survival rates were observed in nonviral AC patients. CONCLUSIONS: AC without viral infections is the main indication for LT in southeastern Spain although its frequency has decreased in last decade. AC is a good indication for LT for its high survival rate and few posttransplant complications. Despite having a high percentage of pretransplant complications (ascites and encephalopathy) but does not appear to influence survivals being observed posttransplant survival rates above those expected. Conversely, viral infections in the patient with AC decrease patient survivals. The main future goals are design new strategies to detect, treat, and reduce AC frequency in our population and know alcoholic recidivism rate posttransplant in our population.
