title: Characteristics of body composition and nutritional status in patients receiving hemodialysis therapy for more than 30 years.
abstract: OBJECTIVE
  We investigated the body composition and nutritional status of extremely long-term (more than 30 years) hemodialysis patients.
  
  
  METHODS
  Eighty outpatients receiving maintenance hemodialysis (including 18 for more than 30 years) were enrolled. We classified the patients according to the duration of hemodialysis therapy (less than 10 years, 10-20 years, 20-30 years, or over 30 years) and compared the laboratory and anthropometric data.
  
  
  RESULTS
  No significant differences in age or the total protein, albumin, total cholesterol, triglyceride or CRP levels were observed. The corrected body mass index (BMI) was significantly lower in the more than 30 years than in the less than 10 years group. The corrected arm muscle area (AMA) was significantly lower in the more than 30 years group than in the other groups.
  
  
  CONCLUSIONS
  In extremely long-term hemodialysis outpatients, the BMI and AMA were reduced, whereas nutritional markers were relatively preserved.
