ABSTRACT

Background: With the aim of improving treatment retention in patients with the onset of alcohol-related liver disease (ArLD), we designed a blended intervention (brief motivational intervention + 'serious game' (SG)). We present the participatory design methodology and outcomes and the usability assessment of the intervention. Methods: (1) The design of the SG was based on the outcomes of two 3-h co-creation sessions with 37 participants (healthcare and technology professionals, patients, and patients' relatives). The brief face-to-face motivational intervention was based on the 5 As Model and adapted to the ArLD population. (2) Usability pilot study: 20 participants (10 ArLD patients + 10 healthcare professionals) received the intervention. System Usability Scale (SUS) and Post-Study System Usability Questionnaire (PSSUQ) were applied to assess the SG usability and patients' satisfaction with it. Weekly semi-structured interviews on the phone were conducted to identify the preferred elements in the SG and those aspects that should be improved. Results: (1) Design: an SG in the form of a gamified web app, consisting of a daily activity for six weeks and adapted brief motivational interviewing. (2) Usability pilot study: usability results were excellent for both patients and healthcare professionals (SUS median score = 85). The general usability, the quality of the information provided by the SG and the quality of the interface were very positively rated in the PSSUQ (overall median score = 2, IQR = 1-2). The best-rated aspects were the provision of feedback, the use of metaphors and the application of audiovisual material. Changes in the design, response mechanics and content were applied after the study. Conclusions: The usability and acceptability of an intervention for increasing retention to treatment in patients with recent onset of ArLD and AUD were excellent for patients and healthcare professionals. A randomized-controlled trial is required to test the efficacy of this approach.

ABSTRACT

BACKGROUND: Effective screening for alcohol-associated liver disease is relevant in the context of chronic, excessive alcohol consumption. Patients with alcohol-associated liver disease are often not diagnosed until their liver disease is decompensated. We analyzed the prevalence and associations of Fibrosis-4 index (FIB-4) values suggestive of advanced liver fibrosis in patients referred for their first treatment of alcohol use disorder (AUD). METHODS: We conducted a cross-sectional, multicenter study of noncirrhotic individuals referred for their first AUD treatment between March 2013 and April 2021. We obtained sociodemographic data, substance use characteristics, and blood samples at admission. We considered a FIB-4 value ≥2.67 suggestive of advanced liver fibrosis and used logistic regression analyses to identify features associated with this value. RESULTS: We included 604 patients (67% male), with a median age at admission of 48 years [IQR: 41-56 years]. The median duration of regular alcohol consumption was 21 years [IQR: 18-30 years] and the median alcohol consumption was 105 standard drink units (SDU)/week [IQR: 63-160 SDU/week]. A FIB-4 value ≥ 2.67 was present in 19.3% of cases. These patients reported more frequent binge drinking (75.4% vs. 66%, p = 0.05) than those with FIB-4 values below 2.67. In multivariate analysis, a history of binge drinking (OR 1.9, 95% CI, 1.05-3.47), anemia (OR 2.95, 95% CI, 1.42-6.11), leukopenia (OR 7.46, 95% CI, 2.07-26.8), and total serum bilirubin >1 mg/dL (OR 6.46, 95% CI, 3.57-11.7) were independently associated with FIB-4 values ≥2.67. CONCLUSIONS: One in five patients admitted to treatment for AUD without evidence of decompensated liver disease have FIB-4 values suggestive of advanced liver fibrosis. The presence of a binge drinking history, anemia, leukopenia, and elevated bilirubin levels is associated with high FIB-4 values.

ABSTRACT

BACKGROUND: Vitamin D deficiency is a risk factor for liver disease, insulin resistance, and beta cell dysfunction. Individuals with alcohol use disorder (AUD) have many comorbidities, with a heavy burden of liver disease and metabolic complications, including type 2 diabetes mellitus (T2DM). OBJECTIVE: We aimed to analyze the prevalence and associations of vitamin D deficiency in patients admitted for in-hospital treatment of AUD. METHODS: A cross-sectional study was conducted in patients consecutively admitted for the treatment of AUD between January 2017 and October 2023. Sociodemographic data, substance use characteristics, and blood parameters were available at admission. Vitamin D status was assessed through the serum concentrations of 25-hydroxyvitamin D [25(OH)D] levels using a direct competitive chemiluminescent immunoassay method. Deficiency of vitamin D was defined as a concentration less than 20 ng/mL; impaired fasting glucose (IFG) was defined by fasting blood glucose >100 mg/dL (5.6 mmol/L), and advanced liver fibrosis by an FIB-4 index >3.25. RESULTS: Two hundred and forty-three patients were included (75% male) with a mean age of 49 ± 10 years, mean BMI of 26.4 ± 7.3, mean alcohol consumption of 163 ± 81 g/day, and a mean duration of AUD of 18.1 ± 11.2 years. Mean 25(OH)D, fasting blood glucose, AST, ALT, and platelets were 14.4 ± 10.2 ng/mL, 103.4 ± 40.9 mg/dL, 55.1 ± 75.8 U/L, 44.8 ± 76.6 U/L, and 206.3 ± 84.8 × 109/L, respectively. The prevalence of vitamin D deficiency was 80.6%, and 41.1% of patients had levels less than 10 ng/mL. IFG was present in 32.3% of patients, and 20.5% had FIB-4 values >3.25. In the multivariable analysis, IFG (OR, 2.51; 95% CI: 1.02-6.17, p = 0.04) and advanced liver fibrosis (OR, 4.27; 95% CI: 1.21-15.0, p = 0.02) were the only factors associated with vitamin D deficiency. CONCLUSIONS: Vitamin D deficiency was very prevalent in this series of patients with AUD and was associated with impaired fasting glucose and advanced liver fibrosis.

ABSTRACT

Alcohol-associated liver disease is currently the leading cause of liver transplantation and liver deaths both in Europe and the United States. Efficacious treatments exist for alcohol use disorder, but they are seldomly prescribed for patients who need them. Besides, the presence of liver cirrhosis can complicate pharmacological treatment choices. In this review, we discuss established and innovative treatment strategies to treat unhealthy alcohol use in patients with alcohol-associated liver disease. We also describe the experience of our own institutions, Hospital Universitari Germans Trias i Pujol in Badalona (Spain) and Yale-New Haven Health and Yale Medicine (Connecticut. United States of America).

ABSTRACT

Substance use is a common health problem, and substance use disorder, which is its most severe presentation, is associated with multiple medical consequences and a negative impact on individual and on population health. Substance use disorder needs to be addressed as any chronic medical condition; therefore, it has to be detected at the early stages and has to be properly treated to prevent drug-related harm. Internists should be able to recognize and treat intoxication and abstinence. Internists should also be able to refer the patient to state of the art long term treatment, aimed to detoxification and treatment induction to promote abstinence and prevent relapse. In this narrative review we will discuss substance use epidemiology, its main medical consequences and its treatment, with a focus on alcohol, opiates, cocaine and other stimulants, cannabis and benzodiazepines.

ABSTRACT

T cells, natural killer (NK) and NKT cells have opposing actions in the development of alcohol-associated liver fibrosis. We aimed to evaluate the phenotype of NK cells, NKT cells and activated T cells in patients with alcohol use disorder (AUD) according to the presence of advanced liver fibrosis (ALF). Totally, 79 patients (51-years, 71% males) were admitted to treatment of AUD. ALF was defined as FIB4-score > 2.67. Immunophenotyping of NK cells (CD3-CD56+CD16+, CD3-CD56+CD16-, CD3-CD56-CD16+), NKT-like (CD3+CD56+), and the activation status of CD4+, CD8+ and regulatory T cells (Tregs) were evaluated according to the HLA-DR expression. Patients had an AUD duration of 18 ± 11 years with a daily alcohol consumption of 155 ± 77 gr/day prior to hospital admission. The values of absolute cells were 2 ± 0.9 cells/L for total lymphocytes, 1054 ± 501 cells/µL for CD4+, 540 ± 335 cells/µL for CD8+, 49.3 ± 24.8 cells/µL for Tregs, 150.3 ± 97.5 cells/µL for NK cells and 69.8 ± 78.3 cells/µL for NKT-like. The percentage of total NK cells (11.3 ± 5.5% vs. 7 ± 4.3%, p < 0.01), CD3-CD56+CD16+ regarding total lymphocytes (9.7 ± 5.1% vs. 5.8 ± 3.9%, p < 0.01), activated CD4+ cells (5.2 ± 3.2% vs. 3.9 ± 3%, p = 0.04) and activated CD8+ cells (15.7 ± 9.1% vs. 12.2 ± 9%, p = 0.05) were significantly higher in patients with ALF. The percentage of CD3-CD56+CD16- regarding NK cells (5.1 ± 3.4% vs. 7.6 ± 6.2%, p = 0.03) was significantly lower in patients with ALF. Activated Tregs (39.9 ± 11.5 vs. 32.4 ± 9.2, p = 0.06) showed a tendency to be higher in patients with ALF. The proportion of activated CD4+ cells (r = 0.40, p < 0.01) and activated CD8+ cells (r = 0.51, p < 0.01) was correlated with the proportion of NKT-like in patients without ALF. Patients with ALF presented an increased NK cytotoxic phenotype and activated T cells concomitant with a decreased NK cytokine-secreting phenotype.

ABSTRACT

BACKGROUND: Fungal plasma biomarkers have not been studied in patients with unhealthy alcohol use and no apparent end-stage liver disease. METHODS: We examined the prevalence of fungal plasma biomarkers, assessed by the presence of anti-Saccharomyces cerevisiae antibodies (ASCA; IgA and IgM), and its disease correlates in patients with alcohol use disorder (AUD). We performed logistic regression analyses to detect the association between clinical and laboratory characteristics and the presence of fungal plasma biomarkers. RESULTS: We included 395 patients (75.9% male, median age of 49 years, and median body mass index of 25.6) who drank a median of 150 g of alcohol daily and had a median duration of AUD of 20 years. ASCA IgA and IgG were present in 34.4% and 14.9%, respectively, and 9.9% had both ASCA IgA and ASCA IgG. The presence of ASCA IgA was associated with male sex (p < 0.01); values of serum aspartate transferase (AST) (p = 0.02), gamma-glutamyl transferase (GGT) (p < 0.01), alkaline phosphatase (ALP) (p < 0.01), and bilirubin in the highest quartile (p < 0.01); Fibrosis-4 Index (FIB-4) values suggestive of advanced liver fibrosis (p < 0.01); and values of the macrophage activation factors sCD163 (p < 0.01) and sCD14 (p < 0.01), the cytokine IL-6 (p = 0.01), and lipopolysaccharide-binding protein in the highest quartile (p < 0.01). The presence of ASCA IgG was associated with omeprazole use (p = 0.04); values of AST (p = 0.04) and GGT (p = 0.04) in the highest quartile; FIB-4 values suggestive of advanced liver fibrosis (p < 0.01); and values of sCD163 (p < 0.01) in the highest quartile. The variables associated with the presence of both ASCA IgA and IgG were male sex (p = 0.04) and values of GGT (p = 0.04) and sCD163 in the highest quartile (p < 0.01). CONCLUSIONS: In AUD patients, the presence of fungal biomarkers in plasma was common and associated with FIB-4 values suggestive of advanced liver fibrosis and with markers of liver damage, monocyte activation, and microbial translocation, male gender, and omeprazole use. These findings suggest that the presence of plasma anti-Saccharomyces cerevisiae antibodies could be used as a biomarker for an elevated risk of progressive liver disease in patients with AUD.

ABSTRACT

INTRODUCTION: Hypomagnesemia (hypoMg) has not yet been extensively studied in alcohol use disorder (AUD) . We hypothesize that chronic, excessive alcohol consumption favors oxidative stress and pro-inflammatory alterations that may be exacerbated by hypoMg. The objective of this study was to analyze the prevalence and associations of hypoMg in AUD. PATIENTS AND METHODS: Cross-sectional study in patients admitted for a first treatment of AUD in six tertiary centers between 2013 and 2020. Socio-demographic, alcohol use characteristics, and blood parameters were ascertained at admission. RESULTS: 753 patients (71% men) were eligible; age at admission was 48 years [IQR, 41-56 years]. Prevalence of hypoMg was 11.2%, higher than that observed for hypocalcemia (9.3%), hyponatremia (5.6%), and hypokalemia (2.8%). HypoMg was associated with older age, longer duration of AUD, anemia, higher erythrocyte sedimentation rate, gamma-glutamyl transpeptidase, glucose levels, advanced liver fibrosis (FIB-4 ≥3.25) and estimated glomerular filtration rate (eGFR) < 60 mL/min. In multivariate analysis, advanced liver fibrosis (OR, 8.91; 95% CI, 3.3-23.9) and eGFR < 60 mL (OR, 5.2; 95% CI, 1.0-26.2) were the only factors associated with hypoMg. CONCLUSIONS: Mg deficiency in AUD is associated with liver damage and glomerular dysfunction suggesting that both comorbidities should be assessed in the course of serum hypoMg.

ABSTRACT

Natural killer (NK) cells play a therapeutic role in liver fibrosis (LF). We aimed to analyze NK cells in heavy drinkers without cirrhosis or decompensated liver disease and establish correlations with other related subpopulations. Data on sociodemographic characteristics, alcohol consumption, laboratory parameters, and immunophenotyping of NK (CD16+/CD56+), T (CD3+), B (CD19+), NKT (CD16+/CD56+/CD3+), and cytotoxic (CD3-CD8+) cells were collected. Fibrosis-4 (FIB-4) scores were used to compare patients without (FIB-4 < 1.45) and with (FIB-4 > 3.25) advanced LF (ALF). We included 136 patients (76% male) with a mean age of 49 years who had a 15-year alcohol use disorder (AUD) and alcohol consumption of 164 g/day. Patients with ALF (n = 25) presented significantly lower absolute total lymphocyte, T cell, B cell, and NKT cell numbers than patients without LF (n = 50; p < 0.01). However, the NK cells count was similar (208 ± 109 cells/µL vs. 170 ± 105 cells/µL) in both groups. The T cells percentage was lower (80.3 ± 5.6% vs. 77 ± 7%; p = 0.03) and the NK cells percentage was higher (9.7 ± 5% vs. 13 ± 6%; p = 0.02) in patients with ALF than in those without LF. The percentages of NK cells and T cells were inversely correlated in patients without (r = -0.65, p < 0.01) and with ALF (r = -0.64; p < 0.01). Additionally, the NK cells and CD3-CD8+ cell percentages were positively correlated in patients without (r = 0.87, p < 0.01) and with (r = 0.92; p < 0.01) ALF. Conclusions: Heavy drinkers without decompensated liver disease showed an increase in NK cells related to T cells lymphopenia and an increase in cytotoxic populations. The interaction of NK cells with other subpopulations may modify alcohol-related liver disease progression.

ABSTRACT

BACKGROUND: The association between markers of inflammation (interleukin (IL)-6 and IL-10), monocyte activation (sCD163 and sCD14), and microbial translocation (lipopolysaccharide (LPS) and LPS binding protein) and liver fibrosis in patients with alcohol use disorder (AUD) and no overt liver disease is not well established. METHODS: We studied patients admitted for treatment of AUD at two hospitals in Barcelona. Advanced liver fibrosis (ALF) was defined as FIB-4 > 3.25. RESULTS: A total of 353 participants (76.3% male) were included and 94 (26.5%) had ALF. In adjusted correlation analyses, sCD163, sCD14, IL-6, IL-10, and LPS binding protein levels directly correlated with FIB-4 values (adjusted correlation coefficients 0.214, 0.452, 0.317, 0.204, and 0.171, respectively). However, LPS levels were inversely associated with FIB-4 (-0.283). All plasma marker levels in the highest quartile, except LPS, were associated with ALF (sCD163, sCD14, IL-6, IL-10, and LPS binding protein: adjusted odds ratio (aOR) 11.49 (95% confidence interval 6.42-20.56), 1.87 (1.11-3.16), 2.99 (1.79-5.01), 1.84 (1.11-3.16), and 2.13 (1.30-3.50), respectively). Conversely, LPS levels in the lowest quartile were associated with ALF (aOR 2.58 (1.48-4.58), p < 0.01). CONCLUSION: In AUD patients, plasma levels of the markers of inflammation, monocyte activation, and microbial translocation are associated with ALF.

ABSTRACT

Hepatitis C virus (HCV) infection and unhealthy alcohol use are major drivers of the burden of liver disease worldwide and commonly co-occur. Assessment of underlying liver damage is a cornerstone of the clinical care of patients with chronic HCV infection and/or unhealthy alcohol use because many of them are diagnosed at advanced stages of disease. Early diagnosis of liver disease before decompensated liver cirrhosis becomes established is essential for treatment with direct acting antivirals and/or abstinence from alcohol consumption, which are the main therapeutic approaches for clinical management. In this review, we discuss current knowledge around the use of non-invasive methods to assess liver disease, such as abdominal ultrasound, controlled attenuation parameter, transient elastography, magnetic resonance imaging, and indices based on serum markers of liver injury.

ABSTRACT

Banana, the main export fruit for Colombia, is threatened by Fusarium wilt (FWB), caused by Fusarium oxysporum f. sp. cubense (Foc), tropical race 4 (TR4). Pathogen containment through disinfecting tools, machinery, shoes, and any means that may carry contaminated soil particles with proper disinfectants is at the forefront of disease management. In this study, the biocide efficacy of 10 commercial quaternary ammonium compounds (QACs) products and one based on glutaraldehyde (GA) were evaluated on both reproductive structures (microconidia and macroconidia) and survival spores (chlamydospores) of Foc TR4 (strain 140038) isolated from La Guajira, Colombia. QACs were evaluated at 1200 ppm and two exposure times: <1 and 15 min in the absence or presence of soil. For GA disinfectant, four different concentrations (500, 800, 1200, and 2000 ppm) were evaluated at both contact times in the presence of soil. In the absence of soil, all QACs showed 100% biocidal efficiency against microconidia, macroconidia, and chlamydospores at both <1 and 15 min. The presence of soil decreased the efficacy of disinfectants, but some of them, such as QAC3_1st, QAC7_4th, and QAC5_4th, showed 98%, 98%, and 100% efficacy against Foc TR4 chlamydospores, respectively, after <1 min of contact time. For instance, the GA-based disinfectant was able to eliminate all Foc TR4 propagules after 15 min for all concentrations tested.

ABSTRACT

Objective: Cocaine Use Disorder (CUD) has been associated with multiple complications and premature death. The purpose of the present study was to analyze the relationship between baseline medical comorbidity and long-term medical outcomes (i.e., hospitalization, death) in a cohort of patients primarily admitted for detoxification. In addition, we aimed to analyze cause-specific mortality. Methods: longitudinal study in CUD patients admitted for detoxification between 2001 and 2018. Substance use characteristics, laboratory parameters and medical comorbidity by VACS Index were assessed at admission. Follow-up and health-related outcomes were ascertained through visits and e-health records. Kaplan-Meier and Cox regression models were used to analyze survival and predictors of hospitalization and death. Results: 175 patients (77.7% men) were included. Age at admission was 35 years [IQR: 30-41 years], 59.4% of the patients being intranasal users, 33.5% injectors, and 7.1% smokers. Almost 23% of patients had concomitant alcohol use disorder, 39% were cannabis users and 9% opiate users. The median VACS Index score on admission was 10 points [IQR: 0-22]. After 12 years [IQR: 8.6-15 years] of follow-up there were 1,292 (80.7%) ED admissions and 308 (19.3%) hospitalizations. The incidence rate of ED admission and hospitalization was 18.6 × 100 p-y (95% CI: 15.8-21.8 × 100 p-y). Mortality rate was 1.4 × 100 p-y (95% CI: 0.9-2.0 × 100 p-y) and, baseline comorbidity predicted hospitalization and mortality: those with VACS Index >40 were 3.5 times (HR:3.52, 95% CI: 1.19-10.4) more likely to dye with respect to patients with VACS < 20. Conclusion: addiction care warrants optimal stratification of medical comorbidity to improve health outcomes and survival of CUD patients seeking treatment of the disorder.

ABSTRACT

OBJECTIVES: There are sex differences in the pattern of alcohol consumption and in the complications of alcohol use disorder (AUD). We aimed to identify sex-specific differences in the factors associated with alcohol withdrawal syndrome (AWS) among patients that requested a first treatment for AUD. METHODS: We enrolled 313 patients (75% men) with a Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) AUD diagnosis that started treatment between 2014 and 2016. We collected socio-demographics, the type and amount of alcohol and other substances consumed, and clinical and laboratory parameters. According to Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) AUD criteria, AWS occurred when patients experienced 2 or more clinical signs/symptoms and/or consumed alcohol to relieve symptoms. Logistic regression models were used to determine factors associated with AWS according to sex. RESULTS: The median age of participants was 50 years (interquartile range [IQR]: 43-54 years). The median age of starting alcohol consumption was 16 years (IQR: 14-18 years). Notably, 69% of participants smoked tobacco, and 61% had a family history of AUD; 18% currently used cannabis, and 7.7% used cocaine. Overall, 73% of patients exhibited AWS criteria, and men (76.5%) were more likely than women (64.6%) to report AWS (P = 0.038). In the adjusted analysis, factors associated with AWS were the age at starting alcohol consumption (odds ratio [OR] for every 5 years = 1.89, 95% confidence interval [CI]: 1.69-2.08), and cannabis use (OR = 2.8, 95% CI: 1.04-7.7) in men, and a family history of AUD in women (OR = 2.85 95% CI: 1.07-7.54). CONCLUSIONS: factors associated with AWS differ by sex which may have clinical implications for proactive management of AWS during treatment for AUD.

ABSTRACT

BACKGROUND: The effect of concomitant cocaine and cannabis use on monocyte activation and inflammation in patients with alcohol use disorder (AUD) is unknown. METHODS: To analyze the impact of cocaine and cannabis use on levels of markers of monocyte activation (sCD163 and sCD14) and systemic inflammation (interleukin-6 [IL-6]) in AUD patients admitted for hospital treatment between 2013 and 2018. Clinical and laboratory parameters were obtained upon admission. IL-6, sCD163, and sCD14 were measured in frozen plasma samples. We performed logistic regression to detect associations between cocaine and cannabis use and markers of monocyte activation and inflammation in the highest quartile. RESULTS: A total of 289 patients (77.5 % male) were included (median age = 50 years). The median alcohol intake upon admission was 142 g/day. The median duration of AUD was 20 years. Of the 289 patients with AUD, 76 % were active smokers, 23.1 % and 22.1 % concomitantly used cocaine and cannabis, respectively The median levels of IL-6, sCD163, and sCD14 were 4.37 pg/mL, 759 ng/mL, and 1.68 × 106 pg/mL, respectively. We did not detect associations between cocaine use and inflammation or monocyte activation. Cannabis use was associated with a higher odds of having sCD163 levels in the highest quartile (adjusted odds ratio = 2.34, 95 % confidence interval = 1.07-5.15, p = 0.03). Cannabis use was not associated with inflammation. CONCLUSION: In this series of AUD patients the concomitant use of cannabis use was associated with sCD163 levels that were in the highest quartile, consistent with monocyte activation.

BACKGROUND: Alcohol use disorder (AUD) is associated with changes in cellular immunity. The objective of the present study was to analyze the contribution of AUD to the differentiation of T cells and associations with advanced liver fibrosis (ALF). METHODS: This cross-sectional study included patients admitted for treatment of AUD between 2013 and 2016. T cell immune-phenotyping defined four profiles of cellular differentiation according to the expression of CCR7 and CD45RA: naive T cells, central memory (TCM) cells, effector memory (TEM) cells, and terminal effector (TEMRA) cells. CD4+ memory cells were subdivided into Th1, Th2, and Th17 according to the expression of CXCR3 and CCR6. The stages of cellular differentiation were compared to healthy controls. ALF was defined as FIB-4 > 3.25. RESULTS: Seventy-nine patients (81% men) with a median age of 50 years (IQR: 45-56 years) and median ethanol consumption of 150 g/day (IQR: 100-200 g/day) were included in the study. Compared to healthy controls, patients with AUD had fewer CD4+ naive cells (p < 0.001), more TCM and TEM cells (p = 0.003 and p = 0.050, respectively), and larger Th2 populations (p = 0.03). Among CD8+ cells, the percentage of TCM, TEM, and TEMRA were higher in patients with AUD than in the healthy controls (p < 0.05). Patients with ALF had fewer CD4+ and CD8+ naive cells (p < 0.05) and more CD4+ memory cells than patients without ALF. CONCLUSIONS: Altered lymphocyte differentiation in AUD patients suggests immunosenescence. An increase in memory cells and decrease in naive cells is associated with ALF.

ABSTRACT

OBJECTIVE: We aimed to analyze sex differences in the DSM-5 criteria among patients admitted to  their first treatment of alcohol use disorder (AUD). METHODS: Assessment of AUD was carried out using DSM-5 diagnostic criteria in a multicenter study (CohRTA) within the Spanish Network on Addictive Disorders. Further, baseline questionnaires including socio-demographics, family history, lifetime alcohol consumption and other substance use, as well as clinical and laboratory parameters were obtained during admission. RESULTS: 313 patients (74.8%M) were eligible; mean age at first AUD treatment was 48.8 years (standard deviation (SD): 9.9 years). Age at onset of alcohol use was 15.9 years (SD: 3.3 years) and age at starting regular alcohol consumption was 25.6 years (SD: 9.6 years). Almost 69.3% of patients were tobacco smokers and 61% had family history of AUD. Regarding other substance use, 7.7% were current cocaine users and 18.2% were cannabis users. Women started regular alcohol consumption later than men (p<,001) and used benzodiazepines more frequently (p=.013). According to DSM-5, 89.5% of cases had severe AUD (≥6 criteria). In the adjusted analysis (logistic regression), men were more likely to neglect major rules (OR=1.92, 95%CI: 1.06-3.48) and to have hazardous alcohol use (OR=3.00, 95%CI: 1.65-5.46). DISCUSSION: DSM-5 detects sex differences in patients seeking their first AUD treatment. Social impairment and risky alcohol use are significantly more frequent in men.


Objetivo: Analizar las diferencias de sexo en los criterios diagnósticos del DSM-5 de los pacientes que solicitan un tratamiento para el trastorno por uso de alcohol (TUA) por primera vez. Métodos: Pacientes incluidos entre enero 2014 y marzo 2016 en el estudio multicéntrico CohRTA de la Red de Trastornos Adictivos. El diagnóstico del TUA se realizó mediante el DSM-5. Además, se recogieron datos sociodemográficos, sobre el consumo de alcohol y otras sustancias, variables clínicas y una analítica general. Resultados: se incluyeron 313 pacientes (74,8% hombres); la edad al inicio del primer tratamiento fue de 48,8 años (desviación estándar (DE): 9,9 años), la edad al inicio del consumo de alcohol de 15,9 años (DE: 3,3 años) y la de inicio del consumo regular de 25,6 años (DE: 9,6 años). Un 69,3% de los pacientes eran fumadores y un 61% tenían antecedentes familiares de TUA. Un 7,7% eran consumidores de cocaína y un 18,2% de cannabis. Las mujeres iniciaron el consumo regular de alcohol más tarde que los hombres (p<,001) y usaban benzodiacepinas con mayor frecuencia (p=,013). Según el DSM-5, el 89,5% de los pacientes presentaban un TUA grave (≥6 criterios). En el análisis ajustado (regresión logística), los hombres tenían mayor probabilidad de presentar el criterio diagnóstico relacionado con el incumplimiento de los deberes fundamentales en el trabajo o en el hogar (OR=1,92, IC95%: 1,06-3,48) y el criterio diagnóstico de consumir alcohol en situaciones de riesgo físico (OR=3,00, IC95%: 1,65-5,46). Discusión: El DSM-5 detecta diferencias de sexo en pacientes que solicitan el primer tratamiento del TUA. El deterioro social y el consumo de alcohol de riesgo son significativamente más frecuentes en hombres.
