Brief summary
This RCT intends to investigate the use of oral Riboflavin (Vitamin B2) for reduction of blood glutamate levels in the setting of acute alcohol withdrawal. Participants will be patients admitted to an inpatient hospital unit diagnosed with acute alcohol withdrawal. In addition to receiving care as usual, they will be randomized to receive either 100mg TID riboflavin or an identically dosed placebo. The primary outcome measure will be blood glutamate levels. Secondary outcomes will include measures of alcohol withdrawal and alcohol craving. The investigators hypothesize that those in the riboflavin group will have lower blood levels of glutamate, as well as decreased symptoms of alcohol withdrawal.
Detailed description
General Investigational Plan Hypotheses: 1. Aim 1: Measure the impact of daily oral riboflavin supplementation on blood Glu levels. Hypothesis 1: Patients receiving riboflavin will have significant reductions in blood Glu levels, as compared to placebo. 2. Aim 2: Observe the impact of oral riboflavin on CIWA-AR scale scoring. Hypothesis 2: Riboflavin will significantly reduce the active group's CIWA-AR scores, and will result in fewer symptom triggered benzodiazepine doses, as compared to placebo. Plan: The proposed study would apply a recently identified method using vitamin B2 (riboflavin) to reduce excess brain Glu activity in veterans in acute alcohol withdrawal. This method of glutamate scavenging, was identified in a 2018 as a way to reduce glutamate associated brain damage which typically occurs after stroke. When tested in human patients immediately following stroke, the intervention demonstrated efficacy through better structural and functional outcomes when compared to placebo. Improvements persisted at 3 months after the initial stroke, and were not associated with any known side effects. Administration of riboflavin quickly decreases Glu levels in both the blood and brain, as measured using chromatography and Magnetic Resonance Imaging (MRI), respectively. As riboflavin's Glu reducing properties have just been discovered, this method has only been applied to the treatment of stroke, and has yet to be studied outside of the field of neurology. Further, oral riboflavin has not been investigated as a method of glutamate reduction. The hyperglutamatergic state in patients with alcohol withdrawal provides one opportunity for such an investigation, one that may lead to future studies improving treatments of alcohol withdrawal. Chronic, as well as acute alcohol users have both elevated extracellular glutamate as well as changes to glutamate receptors and transporters. These changes appear play a role in the rewarding effects of alcohol, and contribute to the symptoms of withdrawal. A positive correlation exists between CSF levels of glutamate and the severity of alcohol dependence, and patients in acute withdrawal have measurably increased levels of glutamate in their peripheral blood. During early withdrawal, elevated glutamate levels have been observed in the hippocampus and anterior cingulate cortex, returning to normal 3 days after symptom resolution. Given this information, riboflavin may provide a safe, effective, and affordable intervention to normalize the hyperglutamatergic state associated with alcohol withdrawal. The proposed study would investigate this hypothesis in patients admitted to the inpatient psychiatry unit in acute alcohol withdrawal. Methods: Participants would be recruited on the inpatient psychiatry unit as they were admitted. The primary teams/on call residents would be asked to page a study member if a patient was admitted on the standard protocol for alcohol withdrawal: the Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar). The study coordinator would consent the patient, and they would be randomized to either the placebo or riboflavin group. They would then receive TID oral dosing of either 100mg riboflavin or placebo, in addition to treatment as usual. The primary outcome would be daily blood glutamate levels, obtained with the normal morning labs. Secondary outcomes would CIWA scores, number of symptom-triggered benzodiazepines given, anxiety, and alcohol craving scores (using standardized measures).
