Background: Little is known about the course of the symptoms of depression/anxiety and the factors predictive of such courses in hemodialysis (HD) patients. This study aimed at evaluating the possible changes of Beck Depression Inventory (BDI) and Hamilton Anxiety Rating Scale (HARS) over time, and factors associated with such changes in HD patients., Methods: We screened 110 patients for study participation. Of these, 30 were excluded because of dialytic vintage <6 months, alcohol/substance abuse, inability to answer to the questionnaires, diagnosis of psychotic or neurological disorders or recent stressful life events. Eighty patients were included in the study and BDI, HARS, Charlson Comorbidity Index, SF-36 Vitality Subscale, Mini-Mental State Examination (MMSE), routine laboratory parameters, C-reactive protein (CRP) and interleukin-6 were measured at baseline. The 18-month course of BDI and HARS was measured in patients with baseline BDI ≤14., Results: At baseline, 42 patients had BDI >14 and 38 patients ≤14. In patients with BDI ≤14, the BDI decreased/remained stable in 19 and increased in 19. Patients with increased BDI had lower baseline MMSE (22.6 ± 2.6 vs. 25.9 ± 2.7, p=0.004) and higher baseline serum CRP (6.07 ± 4.2 vs. 1.64 ± 1.59, p=0.003). At multivariate analysis the relationship between BDI changes and MMSE and serum CRP was statistically significant. In 25 patients, the HARS decreased/remained stable, while in 13 it increased. Characteristics of the 2 groups of patients did not differ significantly., Conclusions: In a meaningful proportion of HD patients, symptoms of depression worsen over time, and CRP and MMSE are independent predictors of such change.

Objective: We aimed at evaluating the association between appetite and symptoms of depression and anxiety, cognitive dysfunction, fatigue, and comorbidities in patients on hemodialysis (HD)., Design: A cross-sectional study was conducted., Setting: The study was conducted in an outpatient HD service of a tertiary level academic hospital., Patients: A total of 90 patients on HD were evaluated for appetite (during the past week, how would you rate your appetite?), symptoms of depression (Beck Depression Inventory [BDI]) and anxiety (Hamilton Anxiety Rating Scale [HARS]), cognitive dysfunction (Mini Mental State Examination [MMSE]), and comorbidities (Charlson Comorbidity Index)., Main Outcome Measure: Relationship between appetite and symptoms of depression and/or anxiety, cognitive dysfunction, and comorbidities was assessed., Results: In 43 patients, the appetite was very good/good (group 1), in 22, it was fair (group 2), and in 25, it was poor/very poor (group 3). Mean and median BDI were significantly higher in group 3 as well as the percentage of patients with BDI ≥16. Mean and median HARS and the percentage of patients with HARS >13 were significantly higher in group 3. MMSE was significantly lower in group 3 as well as the percentage of patients with MMSE ≤23. Multiple linear regression analysis showed a dependence of appetite by age and BDI (P = .007 and P = .002, respectively)., Conclusions: Anorexia is associated with older age and symptoms of depression in patients on HD., (Copyright © 2012 National Kidney Foundation, Inc.

Objective: Cognitive impairment is relatively common in end-stage renal disease patients on chronic hemodialysis, but the course of cognitive function deterioration in hemodialysis patients is essentially unknown. The present study aimed to evaluate if changes in Mini Mental State Examination (MMSE) over time in hemodialysis (HDP) and elderly (EP) patients differ significantly and determine the variables associated with such possible changes., Methods: In 80 HDP and 160 EP, the MMSE was assessed at baseline and after 1 year. Patients were stratified at baseline and at 1 year into three groups according to the MMSE: normal cognitive function >23; mild-moderate cognitive dysfunction: 18-23; severe cognitive dysfunction: <18. Univariate and multivariate analyses were performed to determine the variables associated with MMSE change over time, Results: One-year median reduction of MMSE was greater in HDP (from 24 to 21) than in EP (from 26 to 25) (P<.0001). A higher percentage of HDP than EP switched from normal to mild-moderate or severe MMSE group (P<.0001). At baseline, MMSE was negatively correlated with hypertension (P=.013), angina (P=.007) and Beck Depression Inventory (P=.041) and positively correlated with education (P=.017) and male gender (P=.015). No factors were found to be significantly associated with change of MMSE between baseline and month 12 in HDP., Conclusion: One-year MMSE reduction was greater in HDP that in EP. No factors were associated with MMSE reduction in HDP. However, it remains likely that cardiovascular comorbidities and low haemoglobin levels are related to such decline., (Copyright © 2010 Elsevier Inc. All rights reserved.)
