| Popis: | The relatively high morbidity and mortality during dialytic therapy for end-stage renal disease (ESRD) in the United States is the subject of current inquiry. Identified risk factors for excess mortality include advanced age, diabetes, and malnutrition exemplified by a low serum albumin level. Parathyroid hormone (PTH) has long been thought to contribute to the toxicity of the uremic syndrome. We reviewed the course of patients maintained by hemodialysis (HD) and peritoneal dialysis (PD) to detect any correlation between the level of PTH when beginning dialytic therapy and subsequent morbidity and mortality. Study cohorts consisted of 175 HD and 113 PD patients followed for up to 9 years. Demographic characteristics such as age, race, gender, diabetic status, and prior months on dialysis, as well as biochemical parameters including albumin, creatinine, cholesterol, intact PTH, calcium, and phosphorus levels at enrollment were evaluated for their effect on patient survival. Expected survival was calculated by Cox proportional hazards analysis. Older age and lower enrollment serum creatinine level were associated with increased mortality in both HD and PD patients, whereas low serum albumin and low serum cholesterol levels also predicted high mortality in HD patients. In both HD and PD, patients with enrollment PTH level of ≤ 65 pg/mL had more than twice the mortality risk of those with PTH ≥ 200 pg/mL. Both observed and expected survival of patients with low PTH were significantly lower than the survival in patients with higher PTH. Five-year HD survivors and four-year PD survivors had significantly higher PTH levels at initiation of dialytic therapy than did those with shorter survival. PTH level correlated with serum creatinine and serum albumin in HD but only with serum creatinine in PD, supporting the inference that patients with high enrollment PTH were better nourished than those with lower PTH. |
