Tidskriftsartikel (refereegranskat)abstract
- The plasma insulin-like growth factor I (IGF-I) level was determined in family members carrying the Swedish amyloid precursor protein (APP) 670/671 mutation with or without Alzheimer’s disease (AD) and in age-matched controls from the same family. Plasma growth hormone (GH) and prolactin (PRL) levels were also determined. Measurement of the plasma IGF-I level by radioimmunoassay revealed a significant reduction only in the family members with AD compared to age-matched controls. However, there was no significant difference in the levels of GH and PRL between the mutation carriers with or without AD and their respective age-matched controls. These findings indicate that the mechanism(s) regulating GH and PRL were preserved and those regulating IGF-I levels might be affected in AD patients with the Swedish APP 670/671 mutation.
