Abstract

Objective: the investigation of the relationship between different basic biochemical parameters of bone metabolism in galactosaemia patients. Methods: Study participants included twenty two patients with an average age 7.97±5.1 years, early diagnosed by newborn screening and dietary treated. Serum biochemical factors including calcium, phosphate, magnesium, alkaline phosphatase (ALP), creatinine, albumin, lipidaemic factors, vitamin-D, hemoglobin and ferritin were determined during a routine biochemical physical examination. Z-BMI, Z-Wt and Z-Ht were estimated for the assessment of normal or delayed growth. Results: Estimated biochemical variables did not demonstrate significant differences between patient groups (e.g. males-females, galactosaemia subtypes). Creatinine manifested lower values whereas ALP manifested highest values as compared to reference ranges. Significant differences were observed with respect to BMI estimates as well as Vitamin D vs. age, body weight vs. height in females. Vitamin D was negatively correlated to creatinine and HDL. Calcium was negatively correlated to creatinine, in all patients. Conclusion: These findings suggest that there is a place for periodic monitoring of basic biochemical bone profile in galactosaemic patients, in order to detect early subtle changes in bone metabolism.
