Summary:

      The proposed study will evaluate the response and remission rates for major depressive
      disorder (MDD) in end-stage renal disease (ESRD) patients undergoing maintenance hemodialysis
      (HD) treated with bupropion or fluoxetine for 12 weeks. In addition, the study will document
      the relative tolerability and safety, and longitudinally contrast the effects of bupropion
      and fluoxetine on measures of cognitive function, fatigue, inflammation, and tryptophan (TRP)
      and TRP catabolites in blood. It is hypothesized that both drugs will significantly reduce
      MDD symptoms from baseline, and be tolerable and safe, but bupropion will be associated with
      greater reduction in pro-inflammatory cytokines, cognitive impairment, and fatigue compared
      with fluoxetine.

      The Specific Aims of this study are:

      Aim 1: Determine the efficacy of bupropion and fluoxetine in treatment of MDD in ESRD/HD
      patients.

      Aim 2: Determine whether longitudinal change in MDD symptoms, cognitive dysfunction, and
      fatigue differ between bupropion and fluoxetine.

      Aim 3: Determine whether longitudinal change in MDD symptoms, cognitive dysfunction, and
      fatigue correlate with change in inflammation, measures of TRP availability to brain, or
      neurotoxic TRP metabolites.

      Hypotheses:

        1. Bupropion and fluoxetine will both show efficacy in treating MDD;

        2. Bupropion will lead to greater improvement in cognitive dysfunction and fatigue than
           fluoxetine; and

        3. Change in cognition and fatigue over time will correlate with change in c-reactive
           protein (CRP) and quinolinic acid and change in overall depression score will correlate
           with measures of TRP availability.
