Study of HMB-enriched Amino Acid Supplementation in Patients With Alcoholic Liver Disease and COVID-19
What this study is about
Patients with COVID-19 and comorbidities including alcohol associated liver disease (ALD) are at risk for severe illness and abrupt or sudden clinical deterioration with ventilatory failure. â-hydroxy â-methyl butyrate (HMB), a non-nitrogenous leucine metabolite with anabolic properties, increases muscle mass and contractile function and enhances immune function.
View original scientific description
Patients with COVID-19 and comorbidities including alcohol associated liver disease (ALD) are at risk for severe illness and abrupt or sudden clinical deterioration with ventilatory failure. â-hydroxy â-methyl butyrate (HMB), a non-nitrogenous leucine metabolite with anabolic properties, increases muscle mass and contractile function and enhances immune function. We aim to study the natural course of COVID-19 in patients with ALD and test whether HMB can affect ventilatory deterioration and improve short and long-term morbidity, mortality, and recovery from critical illness in symptomatic COVID-19 patients with ALD.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- A. Cases: Patients with ALD and COVID-19 pneumonia:
- Clinical, imaging, laboratory, and/or histological diagnosis of alcoholic cirrhosis and/or alcoholic hepatitis
- Child Pugh score 5-8, serum creatinine \<3, Model for End Stage Liver Disease score (MELD) \<25
- Diagnosis of COVID-19 pneumonia as defined by the WHO criteria: confirmed SARS-CoV-2 infection by PCR, evidence of bilateral pulmonary infiltrates on chest radiograph (CXR) or computed tomography (CT) and SpO2 \<93% or on oxygen supplement
- Age of 21 years or older B. Controls: Patients without alcoholic liver disease (Non-ALD) and COVID-19 pneumonia:
- Diagnosis of COVID-19 pneumonia as defined by the WHO criteria: confirmed SARS-CoV-2 infection by PCR, evidence of bilateral pulmonary infiltrates on chest radiograph (CXR) or computed tomography (CT) and SpO2 \<93% or on oxygen supplement
- Age of 21 years or older
Exclusion criteria
- (Both Cases and Controls)
- Patients requiring active ventilator support
- Anticoagulant/antiplatelet therapy (for those in the biopsy arm, see Randomization schema. If clinically feasible, patients will be asked to hold their anticoagulants for the muscle biopsy after physician review),
- Recent gastrointestinal bleeding (\<3 months)
- Advanced organ diseases: congestive heart failure (NYHA class 3 and 4), chronic obstructive pulmonary diseases (COPD) (GOLD stage 3 and 4), chronic kidney disease (Cr\>3), metastatic malignancy
- Medications that alter muscle protein metabolism except systemic corticosteroids
- Unwillingness/ Inability to sign informed consent
Where
- Cleveland, Ohio
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
