Anxiety and depression in maintenance dialysis patients: preliminary data of a cross-sectional study and brief literature review.

BACKGROUND: Anxiety and depression affect the quality of life of maintenance dialysis (MD) patients. There is little information concerning the extent to which the experience of individual hemodialysis treatments engenders anxiety in this patient population. This preliminary study examined the prevalence and severity of anxiety and depression in MD patients and the incidence of anxiety related to dialysis treatment. METHODS: One hundred seventy patients, 155 undergoing maintenance hemodialysis and 15 undergoing chronic peritoneal dialysis, were examined. Inclusion criteria included dialysis vintage of at least 6 months. Patients completed the Beck Anxiety Inventory and Beck Depression Inventory and questionnaires that examined their feelings of anxiety related to individual hemodialysis sessions. RESULTS: Patients' mean age was 56 ± standard deviation of 16 years; dialysis vintage, 55 ± 48 months; 46% were female. The data confirmed a high prevalence of anxiety and depression in MD patients. Many MD patients become anxious, often severely, by merely going for routine hemodialysis treatment and also owing to such common events as being connected to the hemodialyzer by a new person or on hearing their hemodialyzer alarm sound. CONCLUSION: Anxiety and depression are common in MD patients. Many patients who are well established on MD experience anxiety during individual maintenance hemodialysis treatments.

Stress, immunity, and cervical cancer: biobehavioral outcomes of a randomized clinical trial [corrected].

PURPOSE: Cancer diagnosis and treatment imparts chronic stressors affecting quality of life (QOL) and basic physiology. However, the capacity to increase survival by improving QOL is controversial. Patients with cervical cancer, in particular, have severely compromised QOL, providing a population well-suited for the evaluation of novel psychosocial interventions and the exploration of mechanisms by which modulation of the psychoneuroimmune axis might result in improved clinical outcomes. EXPERIMENTAL DESIGN: A randomized clinical trial was conducted in cervical cancer survivors that were enrolled at >or=13 and <22 months after diagnosis (n=50), comparing a unique psychosocial telephone counseling (PTC) intervention to usual care. QOL and biological specimens (saliva and blood) were collected at baseline and 4 months post-enrollment. RESULTS: The PTC intervention yielded significantly improved QOL (P=0.011). Changes in QOL were significantly associated with a shift of immune system T helper type 1 and 2 (Th1/Th2) bias, as measured by IFN-gamma/interleukin-5 ELISpot T lymphocyte precursor frequency; improved QOL being associated with increased Th1 bias (P=0.012). Serum interleukin-10 and the neuroendocrine variables of cortisol and dehydroepiandrosterone revealed trends supporting this shift in immunologic stance and suggested a PTC-mediated decrease of the subject's chronic stress response. CONCLUSIONS: This study documents the utility of a unique PTC intervention and an association between changes in QOL and adaptive immunity (T helper class). These data support the integration of the chronic stress response into biobehavioral models of cancer survivorship and suggests a novel mechanistic hypotheses by which interventions leading to enhanced QOL could result in improved clinical outcome including survival.

Quality-of-life and mortality in hemodialysis patients: roles of race and nutritional status.

BACKGROUND AND OBJECTIVES: Maintenance hemodialysis (MHD) patients often have protein-energy wasting, poor health-related quality of life (QoL), and high premature death rates, whereas African-American MHD patients have greater survival than non-African-American patients. We hypothesized that poor QoL scores and their nutritional correlates have a bearing on racial survival disparities of MHD patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We examined associations between baseline self-administered SF36 questionnaire-derived QoL scores with nutritional markers by multivariate linear regression and with survival by Cox models and cubic splines in the 6-year cohort of 705 MHD patients, including 223 African Americans. RESULTS: Worse SF36 mental and physical health scores were associated with lower serum albumin and creatinine levels but higher total body fat percentage. Spline analyses confirmed mortality predictability of worse QoL, with an almost strictly linear association for mental health score in African Americans, although the race-QoL interaction was not statistically significant. In fully adjusted analyses, the mental health score showed a more robust and linear association with mortality than the physical health score in all MHD patients and both races: death hazard ratios for (95% confidence interval) each 10 unit lower mental health score were 1.12 (1.05-1.19) and 1.10 (1.03-1.18) for all and African American patients, respectively. CONCLUSIONS: MHD patients with higher percentage body fat or lower serum albumin or creatinine concentration perceive a poorer QoL. Poor mental health in all and poor physical health in non-African American patients correlate with mortality. Improving QoL by interventions that can improve the nutritional status without increasing body fat warrants clinical trials.

Mental health, depression, and anxiety in patients on maintenance dialysis.

Depression and anxiety are among the most common comorbid illnesses in people with end-stage renal disease (ESRD). Patients with ESRD face many challenges which increase the likelihood that they will develop depression or anxiety or worsen these conditions. These include a general feeling of unwellness; specific symptoms caused by ESRD or the patient's treatment; major disruptions in lifestyle; the need to comply with treatment regimens, including dialysis schedules, diet prescription, and water restriction; ancillary treatments and hospitalizations; and the fear of disability, morbidity, and shortened lifespan. Depression has been studied extensively in patients on maintenance dialysis, and much effort has been done to validate the proper screening tools to diagnose depression and to define the treatment options for patients on maintenance dialysis with depression. Anxiety is less well studied in this population of patients. Evidence indicates that anxiety is also common in maintenance dialysis. More attention should be paid to measuring the incidence and prevalence and developing methods of diagnosis and treatment approaches for anxiety in patients with ESRD. In this review, we attempted to underscore those aspects of depression and anxiety that have not been investigated extensively, especially with regard to anxiety. The interaction between racial/ethnic characteristics of patients on maintenance dialysis with depression and anxiety needs to be studied more extensively, in order to assess better approaches to healthcare for these individuals.
