title: Enteric dysfunction in patients with asymptomatic HIV-infection versus patients with hypoproteinemia/hypalbuminemia and advanced HIV-infection.
abstract: BACKGROUND
  It is unclear whether enteric dysfunction and protein losses contribute to hypoproteinemia, which heralds poor survival in HIV infection.
  
  
  METHODS
  We investigated alpha-1-antitrypsin-clearance (AAT-CL), D-xylose resorption and total gut transition time in 14 HIV+ patients with hypoproteinemia (serum protein < 6 g/dl, albumin < 3 g/dl, median CD4-cell count 58/microl; (group I)), in 10 asymptomatic HIV+ patients (median CD4-cell count 290/microl, (group II)) and in 15 healthy volunteers (group III).
  
  
  RESULTS
  AAT-CL in group I (16.5 (2.9 278.2) ml/d; median (range)) was higher than in groups II (9.5 (1.7 23.1) ml/d) and III (10.6 (0.8 19.5) ml/d; p = 0.0114). Likewise, D-xylose recovery was on average threefold lower in group I than in groups II (p = 0.0009) and III ( p < 0.0001), whereas total gut transition time was significantly shorter in both HIV-infected groups (group I: 49.8 h (23.5-72.7), p=0.0431; group II: 32.6 h (23-54.6), p=0.0104) than in the healthy controls (group III 61.6 h (39.1-87.7)).
  
  
  CONCLUSIONS
  Thus, impaired intestinal resorption and enteral protein losses may contribute to hypoproteinemia in advanced HIV infection, whereas accelerated intestinal motility may be present already in asymptomatic stages of HIV infection.
