Nonalcoholic steatohepatitis (NASH), or fat-related liver inflammation and scarring is projected to be the leading cause of cirrhosis in the United States (U.S.) within the next few years. Women are at disproportionate risk for NASH, with approximately 15 million U.S. women affected. There is an urgent need to understand risk factors for NASH and its progression in women, and sex hormones may provide a missing link. The investigator's preliminary data support a detrimental role of androgens, or "male sex hormones" on fatty liver in women but no studies have evaluated whether androgens are associated with liver inflammation and/or scarring from fatty liver (aka NASH). To better understand the mechanism by which androgens might promote NASH and/or metabolic co-factors that contribute to NASH, the investigators are conducting a pilot clinical trial to primarily assess the feasibility of using an androgen blocking medication, spironolactone, in women with NASH. Spironolactone was selected because it is has been commonly prescribed for decades with good safety profile and tolerability to treat symptoms of high androgens, like acne and hirsutism in young women. Though primarily a feasibility-focused study, the investigators also aim to explore the pathways by which blocking testosterone receptors might alter the biologic processes that promote NASH and its associated metabolic co-morbidities in women.

The epidemic of opioid overdose deaths continues to rise, killing more persons in 2017 than HIV/AIDS at the height of that epidemic. Medication assisted treatment, including methadone and buprenorphine, is the standard of care for the treatment of opioid use disorder (OUD). However, chronic pain can reduce treatment efficacy during medication assisted treatment and is associated with illicit substance relapse, dropout, and subsequent overdose. Mechanisms by which chronic pain may influence the impulsive decision making (e.g., drug relapse) in persons with OUD have not been well characterized. A better understanding is needed of decision-making in this population. Two factors that can influence decisions to use drugs are impulsivity and acute opioid withdrawal. This proposal will test how chronic pain is associated with increases in impulsive decision making in OUD, whether impulsive decision making is greater when undergoing opioid withdrawal, and how catastrophizing may modify the association between withdrawal and impulsive decision making in patients with chronic pain and OUD. An ideal population for this developmental research project are methadone maintained patients, who show high treatment attendance rates and will therefore assure study efficiency and reliable completion.
