A Cochrane review [Abstract] 1 included 8 studies with a total of 282 subjects (with data available from 248). The antibiotic regimens, duration of treatment and follow-up varied between trials.
Four trials compared oral versus parenteral antibiotics. There was no statistically significant difference between the two groups in the remission rate 12 or more months after treatment (RR RR 0.94, 95% CI 0.78 to 1.13; three trials, 118 participants). There was also no significant difference between the two groups in the occurrence of mild adverse events (11/64 versus 8/54; RR 1.08, 95% CI 0.49 to 2.42; three trials, 118 participants) or moderate and severe adverse events (3/49 versus 4/42; RR 0.69, 95% CI 0.19 to 2.57; three trials, 91 participants). Superinfection occurred in participants of both groups (5/66 in the oral group versus 4/58 in the parenteral group; RR 1.08, 95% CI 0.33 to 3.60; three trials, 124 participants). Single trials with very few participants found no statistical significant differences for remission or adverse events for the following three comparisons: parenteral plus oral versus parenteral only administration; two oral antibiotic regimens; and two parenteral antibiotic regimens. No trials compared different durations of antibiotic treatment for chronic osteomyelitis, or adjusted the remission rate for bacteria species or severity of disease.
Comment: The evidence is downgraded by study quality (inadequate or unclear allocation concealment and lack of blinding).
