ABSTRACT

Bone loss has been shown to be associated with chronic liver disease (CLD) caused by ethanol consumption or viral infection, and trabecular bone is affected more than cortical bone. We therefore used calcaneal ultrasound to compare the bone status of 54 males and 20 females with CLD in northern Nigeria with 88 age- and gender-matched healthy controls. Serum levels of bone-specific alkaline phosphatase (BSAP) and the N-terminal telopeptide of type-1 collagen (NTx) were also measured to estimate relative rates of bone synthesis and turnover, respectively. The mean stiffness index (SI) of the males with CLD and the male controls were not different; however, the mean SI of the female subjects with CLD was lower than for the female controls (101 vs. 86, p=0.003). The levels of NTx and BSAP were markedly elevated in the males, but not in the females, with CLD. Liver function tests did not correlate with ultrasound parameters or biochemical markers of bone metabolism. These results show that Nigerian women, but not males, with CLD have decreased bone density as assessed by calcaneal ultrasound; however, the high rate of bone turnover in Nigerian males with CLD indicates that they are at risk for bone loss.
