Results: With the exception of expected differences in serum creatinine, estimated GFR, Karnofsky score, albumin, and hemoglobin, there were no significant differences between groups. A total of 69% of patients with chronic kidney disease experienced pain; 55.2% had disordered sleep. Pain was associated with quality-of-life indicators, including depression, burden of illness, and life satisfaction. Disordered sleep correlated with depression, illness burden, social support, and pain frequency. There were no differences in perception of pain or sleep disturbance between patients with chronic kidney disease and control patients.Conclusions: Pain is common in patients with early-stage chronic kidney disease and is associated with patients' perception of lower quality of life. The prevalence of pain, sleep disturbance, and abnormal psychologic status of patients with chronic kidney disease may be similar to outpatients with other chronic medical illnesses.

Pain perception while off HD may be of more importance to patients than pain during HD. The mechanisms underlying the association are unknown but may involve linkage of pain with severity of medical illness or the generation of a maladaptive cytokine response. Multicenter prospective studies of pain interventions using well-validated pain perception tools are needed to establish causal relationships. Interventions directed toward treating pain on non-HD days may improve ESRD patient survival.

Background and objectives:No studies have evaluated the relationship among spirituality, social support, and survival in patients with ESRD. This study assessed whether spirituality was an independent predictor of survival in dialysis patients with ESRD after controlling for age, diabetes, albumin, and social support.Design, setting, participants, & measurements: A total of 166 patients who had ESRD and were treated with hemodialysis completed questionnaires on psychosocial variables, quality of life, and religious and spiritual beliefs. The religious variables were categorized into three scores on a 0 to 20 scale (low to high levels): Spirituality, religious involvement, and religion as coping. Social support was assessed using the Multidimensional Scale for Perceived Social Support. Analyses were also performed including and excluding patients with HIV infection. Religious variables were categorized on the basis of means, medians, and tertiles.Results: In analyses that used religious variables, only the responses on the spirituality scale split at the mean were associated with survival. The association of other religious variables with survival did not reach significance. Social support correlated with spirituality, religion as coping, and religious involvement measures. Only social support and age were associated with survival when controlling for diabetes, albumin concentration, HIV infection, and spirituality.Conclusions: These data suggest that the effects of spirituality may be mediated by social support. Larger, multicenter, prospective studies that use well-validated tools to measure religiosity and spirituality are needed to determine whether there is an independent association of spirituality variables with survival in patients with ESRD.

Background/Aims: Urine microscopy is a useful diagnostic tool; however, the manner in which nephrologists prepare and examine urinary sediment is variable. We developed an acute kidney injury (AKI) cast scoring index (CSI) in order to standardize urinary microscopy. Further, we sought to assess the precision of this scoring system. Methods: Urine from 30 patients with AKI consistent with the syndrome of acute tubular necrosis were collected. Sample preparation was uniform and standardized. A panel of 3 nephrologists blinded to the sample preparation were instructed to grade each slide using the AKI CSI. Subsequently, the AKI CSI was then tested in another 18 patients with AKI to determine if this score could predict nonrenal recovery. Results: The inter-observer agreement index was 99.80%, with a coefficient of variation of 1.24%. Of the 90 paired observations, 98.8% fell within 2 standard deviations of the mean, signifying good agreement. The receiver operator characteristic area under the curve for AKI CSI to predict nonrenal recovery was 0.79. Conclusions: AKI CSI is a simple, novel, reliable scoring system to grade the degree of epithelial cell and granular casts present on urine microscopy. A standardized AKI CSI has the potential to incorporate urinary cast analysis into the advancing field of AKI diagnostics. These preliminary data endorse the notion that the AKI CSI may be useful in predicting renal outcomes.
