Dh. Vanpapendorp et al., BIOCHEMICAL PROFILE OF OSTEOPOROTIC PATIENTS ON ESSENTIAL FATTY-ACID SUPPLEMENTATION, Nutrition research, 15(3), 1995, pp. 325-334
Osteoporosis is the most frequent metabolic bone disorder in developed
communities. No single mechanism can adequately explain the pathophys
iology of osteoporosis. Recently new biochemical markers for metabolic
bone disease, such as osteocalcin and procollagen have been identifie
d and these parameters have been proven to be indicative of bone turno
ver. In this study, markers of bone turnover were monitored in 40 oste
oporotic patients. Patients were divided into four groups to receive o
ne of the following dietary supplements: evening primrose oil; fish oi
l; a mixture of evening primrose and fish oil or olive oil (placebo),
for 16 weeks. Patients supplemented with fish oil showed an increase i
n serum calcium and an increase in urinary calcium clearance (p< 0.05)
. Osteocalcin as well as procollagen increased in the fish oil and the
fish oil/evening primrose oil supplemented groups (p<0.05). Increased
unsaturation of membranes seems to improve calcium absorption while c
hanges in biochemical bone parameters is indicative of stimulation of
osteoblastic activity.
