Symptoms-triggered approach versus fixed-scheduled approach of benzodiazepines for management of alcohol withdrawal syndrome: Non-randomized controlled trial.

BACKGROUND: Alcohol withdrawal syndrome, if untreated, can lead to potentially life-threatening complications. Benzodiazepines are the drugs of choice for the treatment of alcohol withdrawal syndrome. We aimed to compare the symptoms-triggered approach and fixed-dose approach of benzodiazepine administration for treatment of alcohol withdrawal syndrome in regard to the health care utilization measured by the total dose of benzodiazepines, length of hospital stays, and 90-day readmissions rate. METHODS: A single-center prospective non-randomized controlled trial included all patients diagnosed with alcohol withdrawal syndrome. The group of patients admitted between October 1, 2019, and September 30, 2020, were treated with the fixed-scheduled approach (n = 150), while all patients admitted between November 1, 2020, to October 31, 2021, were treated with the symptoms-trigger approach (n = 50). RESULTS: The fixed-dose approach group showed a significant higher 90-day readmissions rate (HR: 2.61; 95% CI = 1.18, 6.84; p = 0.01). Kaplan-Meier survival analysis showed a significantly shorter duration to the first readmission in the fixed-scheduled approach group (HR: 2.3; 95% CI = 5.6, 1.16; p = 0.02). The symptoms-triggered approach group required a significantly lower dose of diazepam (40 mg vs. 10 mg; p < 0.01) and a higher dose of thiamine (800 mg vs. 600 mg; p < 0.01). Length of hospital stay was significantly increased in the symptoms-triggered approach group (3.9 vs. 2.2 days; p < 0.01). DISCUSSION: The use of a symptoms-triggered approach to treat alcohol withdrawal syndrome was associated with a lower 90-day readmission rate, prolonged period to the first readmission, and reduced total dose of benzodiazepines, but longer length of hospital stays. CONCLUSION: The symptoms-triggered approach is safe, cost-effective, and associated with reduced alcohol dependence relapse.

Clinical characteristics and health outcomes in patients with alcohol withdrawal syndrome: an observational study from Oman.

BACKGROUND: Globally, alcohol withdrawal syndrome (AWS) is considered a serious medical diagnosis associated with increasing morbidity and mortality. Little information has been reported on the scope of the problem in Oman. OBJECTIVE: Study clinical characteristics, management, quality of care, and health outcomes of patients managed for AWS. DESIGN: Retrospective medical record review. SETTINGS: University hospital. PATIENTS AND METHODS: The study included all patients with AWS admitted from 1 October 2019 to 30 September 2020. We collected demographic and clinical characteristics and did a univariate analysis of factors related to 90-day readmission. MAIN OUTCOME MEASURES: Length of hospital stay, 90-day read-mission, referral rate to alcohol rehabilitation center. SAMPLE SIZE AND CHARACTERISTICS: 150 male patients with median (IQR) age of 39.5 (32-48) years. RESULTS: Most patients (70.7%, n=106) were smokers and 44 (29.3%) had a history of drug abuse. The average length of hospital stay was 2.3 (0.9-4.6) days. Approximately 9% of total hospital bed days were used to care for patients with AWS. Chronic liver disease (35.3%), diabetes mellitus (24.7%), and hypertension (24.0%) were common among AWS patients. The 90-day readmission rate (32.7%) was high, and there was low referral to alcohol rehabilitation (16.7%). Diabetes and epilepsy were associated with 90-day readmission. CONCLUSION: AWS is an important diagnosis that represents an important burden on acute medical services. Establishing a drug and alcohol service in our institution is an essential step to optimise care for patients with alcohol-related disorders. LIMITATIONS: Retrospective, so unable to collect data on manifestations of AWS such as delirium tremens, which is the most severe form of AWS. Also, the reason for the lack of referral to an outpatient alcohol rehabilitation program was not apparent. CONFLICT OF INTEREST: None.

Rivaroxaban for Treatment of Left Ventricular Thrombus: A Case Report.

BACKGROUND Left ventricular thrombus (LVT) is a complication of left ventricular dysfunction and myocardial infarction (MI) and is associated with systemic thromboembolism. Two-dimensional transthoracic echocardiography (TTE) is considered the first-line diagnostic tool for detection of LVT. Vitamin K antagonists (VKA) targeting an international normalized ratio (INR) from 2 to 3 are the only approved treatments by the Food and Drug Administration (FDA). New emerging observational data support the use of direct oral anticoagulants (DOACs) as an alternative therapeutic option; however, their safety and efficacy have not been assessed in a good-quality randomized controlled trial. CASE REPORT Here, we present a case of a 43-year-old man diagnosed with human immunodeficiency virus (HIV)-associated dilated cardiomyopathy complicated with an LVT. He was treated with rivaroxaban for 9 consecutive months with no interruption of therapy at any point in time; however, he presented to the emergency department with symptoms of decompensated heart failure. A follow-up TTE demonstrated a significant increase in the size of his LVT. This case questions the efficacy of using factor Xa inhibitor (rivaroxaban) as an alternative option for LVT treatment. CONCLUSIONS This case demonstrates a failure of rivaroxaban in treating LVT in a patient with HIV-associated dilated cardiomyopathy. Good-quality randomized clinical trials or prospective studies are required to establish the efficacy and safety of DOACs for LVT treatment as an alternative to VKA.
