title: [Nutritional status and food intake of continuous peritoneal dialysis patients with and without secondary hyperparathyroidism].
abstract: BACKGROUND
  Secondary hyperparathyroidism (SHPT) is a common and early complication in chronic kidney disease (CKD) patients. Studies have suggested that high levels of parathyroid hormone (PTH) may have deleterious effects on the nutritional status of patients with CKD. Thus, the aim of this study was to compare the nutritional status of CKD patients in continuous peritoneal dialysis (CPD) with and without SHPT.
  
  
  OBJECTIVE
  The aim of this study was to compare the nutritional status of CKD patients in continuous peritoneal dialysis (CPD) with and without SHPT.
  
  
  METHODS
  74 patients were evaluated, including adults and seniors, divided into two groups according to PTH levels. In group 1 (n = 18) levels of PTH higher than 300 pg/mL and in group 2 less than or equal to 300 pg/mL. The nutritional status of patients was assessed by anthropometry, biochemical and subjective global assessment (SGA). Food intake was measured by food record for 3 days. We also collected clinical data, such as calcium and serum phosphorus, and the presence of inflammation was assessed by measuring C-reactive protein ultra-sensitive (CRP US).
  
  
  RESULTS
  The average age of the population studied was 54.97 ± 17.06 years, with predominance of adult patients (58.1%) and females (56.8%). The time of CPD expressed in median was 17 months (7.75-33). Through ASG, it was shown a prevalence of 36.5% of the population undernourished. In the analysis of difference between the groups in relation to anthropometry, biochemical indicators and ASG as well as food intake, there were no differences between the groups.
  
  
  CONCLUSIONS
  There were no differences in nutritional status and dietary intake between patients with and without SHPT.
