Outcomes
Primary Outcome Measures
Fatigue Severity Scale (FSS)
This is a psychometrically validated self-report measure of fatigue. This measure consists of 11 items inquiring about the severity of fatigue in different situations during the past week. Scores for each item range from 1 to 7, where 1 indicates strong disagreement and 7 strong agreement. Higher scores indicate higher levels of fatigue. A responder on the FSS is an individual whose FSS total score has decreased by 0.7 its when compared baseline to week 10 (or last observation carried forward); 0.7 refers to the minimally clinical significant difference (MCID) in change over time. We report the number of participants who reached a meaningful reduction in fatigue (equal or more than MCID).
Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form (Q-LES-Q-SF)
The Q-LES-Q - SF is a self-reported questionnaire, with 16 items evaluating overall enjoyment and satisfaction with physical health, mood, work, household and leisure activities, social and family relationships, daily functioning, sexual life, economic status, overall well-being and medications. Responses are scored on a 5-point scale, where higher scores indicate better enjoyment and satisfaction with life (possible range 14-70). Fourteen summated items create the total Q-LES-Q - SF score. Two last items, about medications and overall life satisfaction, are considered independently. Meaningful improvement on the Q-LES-Q to is a change score between baseline and week 10 (or last observation carried forward) of at least 6.8 points; 6.8 refers to the minimally clinical significant difference (MCID) where a score equal to or greater than 6.8 points represents an improved quality of file. We report # with meaningful improvement.
Secondary Outcome Measures
The Short Form (36) Health Survey (SF-36) Physical Component Summary (PCS)
The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. The 8 scales are-vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning mental health. Each scale is directly transformed into a 0-100 scale, the lower the score the more disability and the higher the score the less disability. We calculate the Physical Component Summary (PCS) (representing physical functioning) which represent the items in the SF-36 representing physical functioning (Ware, 2000); as in the sub scales, lower scores indicate greater disability.The norm-based estimate has a mean of 50 and a standard deviation of 10. We report the magnitude of the score change from baseline to week 10 (or the last observation carried forward (LOCF)); positive change scores indicate improvement.
General Symptom Questionnaire (GSQ-30)- Assess Multisystemic Symptom Burden
This is a psychometrically validated 30 item self-report measure of symptom burden. The measure asks participants to rate how bothered they have been with a particular symptom over a 2-week time frame. Responses are made on 5-point Likert scale ranging from "not at all" to "very much" (scored 0-4); and the total score ranges from 0-120. Higher scores indicate more symptom severity. We report the magnitude of the score change (week 10 or last observation carried forward (LOCF)) minus the baseline score; a negative change score indicates improvement.
Patient-Reported Outcomes Measurement Information System (PROMIS-29) Symptom Summary Score on Sleep Disturbance, Pain, Anxiety, Depression, and Low Energy/Fatigue (SPADE)
The PROMIS-29 is a psychometrically validated 29 item self-report measure covering 7 domains. The questions are ranked on a 5-point Likert Scale. The composite score on 5 symptoms of the 7 domains is known as the SPADE summary score (sleep disturbance, pain, anxiety, depression, and low energy/fatigue); this represents the most common chronic symptoms in the general population. Each domain has 5 response options (e.g., 1=not at all to 5=very much), with scale scores ranging from 4 to 20 and higher scores indicating worse symptom severity. Using the scores from these 5 domains, we calculated the average score (SPADE score); the SPADE score ranges from 1 to 5 with higher scores indicating more symptom severity. We report the magnitude of the change in SPADE scores from baseline to week 10 (or the last observation carried forward (LOCF)); a negative change score indicates improvement.
The Short Form (36) Health Survey (SF-36) Mental Component Summary (MCS)
The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. The 8 scales are-vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning mental health. Each scale is directly transformed into a 0-100 scale, the lower the score the more disability and the higher the score the less disability. We calculate the Mental Component Summary (MCS) (representing physical functioning) which represent the items in the SF-36 representing physical functioning (Ware, 2000); as in the sub scales, lower scores indicate greater disability.. The norm-based estimate mean is 50 with a standard deviation of 10. We report the magnitude of the change in scores from baseline to week 10 (or the last observation carried forward (LOCF)); a positive change score indicates improvement.

5. Study Description
Brief Summary
Approximately 10-20% of patients experience ongoing symptoms despite having received standard antibiotic therapy for Lyme disease. Possible explanations for persistent symptoms include persistent infection and/or post-infectious causes. Recent in vitro studies indicate that disulfiram is effective at killing both the actively replicating and the more quiescent persister forms of Borrelia burgdorferi, the microbe that causes Lyme Disease. In this study, the investigators are examining the safety of disulfiram among patients with post-treatment Lyme disease symptoms. The investigators are also conducting a preliminary investigation regarding the relative benefit of 4 vs 8 weeks of treatment with disulfiram.
Detailed Description
Lyme disease, caused by the spirochete Borrelia burgdorferi, is the most common tick-borne illness in the United States. Typically, after being bitten by an infected tick, patients will notice an expanding rash and flu-like symptoms. Most patients recover fully after initial treatment with antibiotics such as doxycycline or amoxicillin. Some patients, however, do not recover fully or their symptoms return within a few months after having completed antibiotic treatment. Common persistent symptoms include fatigue, joint pain, muscle pain, numbness, tingling, burning pains, and changes in mood, memory or mental clarity. These symptoms can last months to years after treatment and, when accompanied by functional impairment, are collectively referred to by the academic community as "Post Treatment Lyme Disease Syndrome (PTLDS)". Patients however typically refer to this constellation of persistent symptoms as "Chronic Lyme Disease".
There are several possible explanations for why patients may have persistent symptoms, including persistent infection and post-infectious changes triggered by the prior infection.
Scientists recently discovered that disulfiram is effective in the lab setting at killing the microbes that cause Lyme disease. Disulfiram is more commonly known as "Antabuse". It is an FDA-approved compound used to assist alcoholics in resisting alcohol consumption. Most remarkable is that disulfiram was effective at killing not only the actively replicating Lyme bacteria (ie, the ones that are typically killed by several antibiotics) but also the relatively dormant or quiescent Lyme bacteria (these are called "drug-tolerant persisters") - these latter spirochetes are the ones that may account for the development of chronic Lyme disease symptoms.
This initial pilot study will focus on patients with persistent symptoms despite having received the standard antibiotic therapy (or more) for Lyme disease. Because no one has yet studied the safety of disulfiram for patients with a history of Lyme disease and because the investigators do not know the optimal treatment duration for disulfiram, the initial effort will have the primary aims of assessing safety and determining whether a longer course of daily treatment is more effective than a shorter course of daily treatment.
The investigators propose therefore a small 14-week randomized placebo-controlled pilot study enrolling 24 patients with persistent symptoms despite prior antibiotic treatment for Lyme disease (known as Post-treatment Lyme Disease Syndrome). Among the 24 disulfiram-treated patients, half will get 8 weeks of disulfiram and the other half will get a shorter duration of disulfiram for 4 weeks followed by 4 weeks of matching placebo. After week 8, patients will be off pills for 2 weeks for the primary week 10 evaluation and then for another 4 weeks for the week 14 follow-up evaluation. This will be a double-blinded study; neither physician nor patient will know which treatment group the patient is assigned to.
With this initial study, the investigators will be able to evaluate the side effects, tolerability and initial signs of the effectiveness of disulfiram in reducing symptoms among the 24 patients assessed. The results of this study will guide the investigators regarding whether a larger definitive randomized trial should be conducted and which treatment schedule is optimal.
