About

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.

Inclusion criteria

• age 30-70 yrs;
• have patent and non-infected arteriovenous fistula or graft;
• are receiving maintenance HD 3 times per week lasting for 3-4 hours;
• serum albumin of ≥ 3.2 g/dl, serum phosphate of <6.5 mg/dl, and serum hemoglobin of ≥9 mg/dl in consecutive two blood tests as per the National Kidney Foundation Disease Outcomes Quality Initiative (NKF KDOQI) guidelines [subjects failing screening due to blood test will be allowed to be re-screened in 30 days];
