Abstract

Aims: Novel bone turnover markers could help with the diagnosis and monitoring of osteomyelitis patients. We compared levels of two bone turnover markers, serum amino-terminal telopeptides (NTx) and bone alkaline phosphatase (BAP), in diabetic patients with and without osteomyelitis. Methods: Matched case-control study was conducted with diabetic patients with and without osteomyelitis. Cases not undergoing immediate amputation were followed with repeat measurements after osteomyelitis treatment and for outcome determination. Results: Analysis included 54 subjects, 27 cases and 27 controls. Median BAP levels were similar between cases and controls at enrollment (p= .55) as were median NTx levels (p= .43). Cases with follow-up data (n=18) had similar bone marker levels at enrollment and 6 weeks. No significant differences in BAP or NTx levels at enrollment or follow-up were seen between cases with poor versus favorable outcomes. Conclusions: No differences in NTx or BAP levels were seen between cases and controls. Cases with follow-up data had similar levels at enrollment and 6 weeks. Lack of difference may be due to small sample size, small areas of bone involved in foot osteomyelitis, or limitations of these specific markers. More research is needed.
