Abstract
Background Despite alcohol use being a risk factor for numerous health-related conditions and alcohol use disorder (AUD) recognized as a disease, there was limited research in India until 2010. This narrative review aims to evaluate AUD-related research in India from 2010 to July 2023. Methods A PubMed search used key terms for AUD in India after 2010. Indian and international journals with regional significance that publish alcohol-related research were searched by each author individually. These were then collated, and duplicates were removed. In addition, we also conducted a gray literature search on focused areas related to AUD. Results The alcohol-related research in India after 2010 focused on diverse areas associated with alcohol use. Some areas of research have received more attention than others. Two major epidemiological surveys conducted in the past decade reveal that around 5% have a problematic alcohol use pattern. Factors associated with alcohol use, like genetic, neurobiological, psychological, and sociocultural, were studied. The studies focused on the clinical profile of AUD, including their correlates, such as craving, withdrawal, alcohol-related harm, and comorbid psychiatric and medical illnesses. During this period, minimal research was conducted to understand AUD's laboratory biomarkers, course, and prognosis. While there was a focus on generating evidence for different psychological interventions for alcohol dependence in management-related research, pharmacological studies centered on anticraving agents like baclofen. Research on noninvasive brain stimulation, such as rTMS, has shown preliminary usefulness in treating alcohol dependence. Very little research has been conducted regarding alcohol policy. Conclusion In the past decade, Indian research on alcohol has focused on diverse areas. Epidemiological and psychological management-related research received maximum attention. Considering the magnitude of the alcohol-related burden, it is essential to prioritize research to other less studied areas like pharmacological management of alcohol dependence and alcohol policy.

The complementarity of phosphatidylethanol in whole blood and ethyl glucuronide in hair as biomarkers for the monitoring of alcohol use. Drug Test Anal 2024; 16:398-405.

Abstract
Monitoring long-term alcohol use and/or abstinence is essential in clinical and medico-legal cases. Analysis of ethyl glucuronide (EtG) in hair provides information on alcohol consumption over several months. However, there is a lag time between ethanol consumption, incorporation of EtG in the hair bulb and hair growing out of the scalp. Phosphatidylethanol (PEth) 16:0/18:1 analysis in whole blood has a detection window of 2-4 weeks, allowing for the detection of recent alcohol consumption. In this study, 2340 paired samples (of hair and venous whole blood from 1170 individuals) were analysed for EtG in hair (hEtG) and PEth 16:0/18:1 in venous whole blood. PEth 16:0/18:1 and hEtG results were subdivided into three categories according to the consensus of SoHT (hEtG) and PEth-NET (PEth): abstinence/low, moderate or excessive alcohol consumption. For hEtG analysis, 446 individuals presented abstinence/low alcohol consumption, of which 2% were classified as excessive alcohol users through PEth 16:0/18:1 analysis. This suggests excessive alcohol consumption in the weeks before sample collection. Out of 483 individuals classified as heavy alcohol users based on hEtG analysis, 14% showed abstinence/low alcohol consumption for PEth 16:0/18:1 analysis, implying that these subjects stopped drinking 2-4 weeks before sample collection. Our results show that the analysis of the two different biomarkers can lead to a more accurate categorisation of individuals. Therefore, we emphasize that for the retrospective investigation of alcohol use, it is necessary to include two alcohol use biomarkers with different detection windows.

Abstract
ABSTRACT Alcohol-associated liver disease (ALD) is the most common cause of advanced hepatic disease and frequent indication for liver transplantation worldwide. With harmful alcohol use as the primary risk factor, increasing alcohol use over the past decade has resulted in rapid growth of the ALD-related healthcare burden. The spectrum of ALD ranges from early asymptomatic liver injury to advanced disease with decompensation and portal hypertension. Compared with those with other etiologies of liver disease, patients with ALD progress faster and more often present at an advanced stage. A unique phenotype of advanced disease is alcohol-associated hepatitis (AH) presenting with rapid onset or worsening of jaundice, and acute on chronic liver failure in severe forms conveying a 1-month mortality risk of 20%-50%. The model for end stage disease score is the most accurate score to stratify AH severity (>20 defined as severe disease). Corticosteroids are currently the only available therapeutic with proven efficacy for patients with severe AH, providing survival benefit at 1 month in 50%-60% of patients. Abstinence of alcohol use, a crucial determinant of long-term outcomes, is challenging to achieve in ALD patients with concurrent alcohol use disorder (AUD). As patients with ALD are rarely treated for AUD, strategies are needed to overcome barriers to AUD treatment in patients with ALD and to promote a multidisciplinary integrated care model with hepatology, addiction medicine providers, and social workers to comprehensively manage the dual pathologies of liver disease and of AUD. Liver transplantation, a definitive treatment option in patients with advanced cirrhosis, should be considered in selected patients with AH, who are unresponsive to medical therapy and have a low risk of relapse to posttransplant alcohol use. Level of evidence and strength of recommendations were evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations system. This guideline was developed under the American College of Gastroenterology Practice Parameters Committee.

Validation of serotonin transporter mRNA as a quantitative biomarker of heavy drinking and its comparison to ethyl glucuronide/ethyl sulfate: A randomized, double-blind, crossover trial. Alcohol Clin Exp Res 2022; 46:1888-1899. [PMID: 36031718 PMCID: PMC9588643 DOI: 10.1111/acer.14931] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 08/02/2022] [Accepted: 08/22/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND The serotonin transporter (SERT) mRNA was previously reported to be a quantitative and pathophysiology-based biomarker of heavy drinking in 5HTTLPR:LL genotype-carriers treated with ondansetron. Here, we validated the potential use of SERT mRNA for quantitative prediction of recent alcohol consumption (in the absence of treatment) and compared it with the known biomarkers ethyl glucuronide (EtG) and ethyl sulfate (EtS). METHODS Binge drinking men and women of European ancestry aged 21 to 65 years were enrolled in a 12-day, in-patient, randomized, double-blind, crossover study, where they were administered three beverage doses (placebo, 0.5 g/kg [0.4 g/kg] ethanol, and 1 g/kg [0.9 g/kg] ethanol for men [women]) individually in three 4-day periods (experiments), separated by minimum 7-day washout period. Diet, sleep, and physical activity were controlled throughout the inpatient experiments. Twenty-nine participants were randomized to receive beverage doses counterbalancing the sequence of treatment and gender within subgroups stratified by SERT genotypes 5HTTLPR:LL+rs25531:AA (LA LA ) versus 5HTTLPR:LS/SS. Peripheral venous blood was collected daily for (1) quantification of SERT mRNA (the primary outcome measure) using qRT-PCR and (2) plasma EtG and EtS levels using tandem mass-spectrometry. RESULTS The association between administered beverage dose and SERT mRNA from completers of at least one 4-day experiment (N = 18) assessed by a linear mixed model was not statistically significant. Significant positive associations were found with beverage dose and plasma EtG, EtS and EtG/EtS ratio (β = 5.8, SE = 1.2, p < 0.0001; β = 1.3, SE = 0.6, p = 0.023; and β = 3.0, SE = 0.7, p < 0.0001, respectively; the C-statistics for discriminating outcomes were 0.97, 0.8, and 0.92, respectively). Additionally, we observed a sequence effect with a greater placebo effect on SERT mRNA when it was administered during the first experiment (p = 0.0009), but not on EtG/EtS measures. CONCLUSION The findings do not validate the use of SERT as a biomarker of heavy drinking. Larger and more innovative studies addressing the effects of placebo, race, gender, and response to treatment with serotonergic agents are needed to fully assess the utility of SERT as a biomarker of heavy and binge drinking.

Positive blood phosphatidylethanol concentration is associated with unfavorable waitlist-related outcomes for patients medically appropriate for liver transplantation. Alcohol Res 2022; 46:581-588. [PMID: 35102553 PMCID: PMC9150771 DOI: 10.1111/acer.14786] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 01/23/2022] [Accepted: 01/25/2022] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Excessive alcohol use is a leading etiology of liver disease and indication for liver transplantation. Accurate measurement of alcohol use remains a challenge in the management of patients in the pre-, peri-, and post-liver transplant settings. Blood 16:0-18:1 phosphatidylethanol (PEth) concentration is a sensitive and specific biomarker of binge and moderate, chronic alcohol use. As PEth has the longest detection window of available blood-based direct alcohol biomarkers for moderate to heavy drinking, it shows promise as an indicator of patterns and chronicity of drinking. However, the utility of PEth in clinical liver transplantation is understudied. This study examines the association of PEth results with liver transplantation waitlist-focused patient outcomes. METHODS Retrospective data for all patients tested for PEth for a one-year period at a tertiary care medical center with an active liver transplantation program were abstracted. Indications for PEth testing, liver transplantation waitlist-related outcomes (e.g., listing and delisting) following testing and associations of PEth results with other parameters were analyzed. RESULTS Over a one-year period, 153 PEth tests were performed on 109 individuals. The most frequent indications for PEth testing were as an objective indicator of alcohol use patterns (86.3%) and to assess alcohol as a putative etiology of liver injury (13.7%). Of the 109 patients, 56 were medically appropriate for liver transplantation. Medically acceptable candidates with unfavorable transplantation waitlist-related outcomes (delisting, deferment of transplant evaluation, deferment of listing until completion of recommended alcohol rehabilitation, and being deemed not a transplant candidate) were at least 3.41 times more likely to have a positive PEth test than those with favorable transplantation waitlist-related outcomes (odds ratio 3.41, confidence interval 3.41 to ∞, p = 0.001). CONCLUSION This single-center study reporting a comprehensive account of PEth utilization at a liver transplant center demonstrates that liver transplantation waitlist-related outcomes are associated with PEth test results. Patients with positive PEth tests were more likely to have unfavorable transplant waitlist-related outcomes. PEth testing has not been validated as a predictor of relapse to drinking in post-transplant patients and because its utility in the pre-transplant setting is unclear its use could lead to disparities in the selection of patients for liver transplantation.

Abstract
Objective: This study aims to explain whether EtG and EtS, which are two non-oxidative ethanol metabolites secreted by the liver and used as markers of alcohol intake related to an incident, were also present in whole blood samples of patients with traffic accident injuries.Methods: EtG and EtS concentrations in all of the whole blood samples were sent to the Forensic Medicine Department of Cukurova University for testing Blood Alcohol Concentrations (BAC) via validated liquid chromatography-tandem mass spectrometer method.Results: The scope of the study covers 200 patients that were admitted to medical services within 12 h following the incident. Of all patients 16.5% were found to be BAC positive, while 35.5 and 23.5 were positive for EtG and EtS, respectively. All samples with a positive BAC result were also positive for EtG and EtS.Conclusion: Detection of EtG and EtS, minor metabolites along with ethanol in the blood can serve as an objective tool to provide further analysis regarding alcohol-related traffic accidents at emergency services.
