No full textTreatment of post-traumatic hand Staphylococcus aureus osteomyelitis with oral linezolid
No full textThe Authors report on the use of linezolid for the treatment of three patients with osteomyelitis. All three patients had post-traumatic multisensitive hand bone methicillin-susceptible Staphylococcus aureus osteomyelitis, which did not respond to antimicrobial regimens including drugs in vitro active against the isolated strains. Clinical cure and microbiologic eradication was obtained with oral linezolid in all three patients. Linezolid was well tolerated. Mild thrombocytopenia was observed in one patient at the end of the third week of treatment and it was promptly resolved after the discontinuation of linezolid. Linezolid minimum inhibitory concentrations (MICs) consisted of 2 mg/l for all three S. aureus isolates while the bactericidal activity in vitro was not present up to the linezolid concentration of 32 mg/l. In spite of a lack of in vitro bactericidal activity, linezolid was effective in curing the patients and eradicating the infection. Trough and peak plasma concentrations of linezolid were above the MICs of the isolates. These values ranged from 3.93 to 14.95 mg/l at trough and 5.03 to 25.91 mg/l at peak. The oral bioavailability, pharmacokinetic profile and antibacterial spectrum of linezolid make this oxazolidonone antimicrobial an attractive drug for the treatment of chronic osteomyelitis. Prolonged administration requires careful surveillance for side effects, until these complications are better understood

No full textA randomized controlled trial of amantadine plus interferon-alpha 2a vs. interferon-alpha 2a alone in naive patients with chronic hepatitis C randomized according to the early virological response to interferon-alpha 2a monotherapy
No full textBACKGROUND:
An early virological response to interferon-alpha treatment is a strong predictor of sustained response, but it has never been exploited to stratify patients in clinical trials.
AIM:
To evaluate the efficacy of amantadine plus interferon-alpha compared with interferon-alpha alone in naive patients with chronic hepatitis C who were randomized on the basis of the early virological response to interferon-alpha.
METHODS:
One hundred and eighty-one patients received recombinant interferon-alpha2a (3 MU three times weekly) for 2 months and 164 were evaluated for early (i.e. month 2) virological response. Hepatitis C virus (HCV) RNA-negative patients (n = 66) were randomized to receive 3 MU of interferon-alpha three times weekly, with or without amantadine (200 mg/day); HCV RNA-positive patients (n = 98) were randomized to receive 6 MU of interferon-alpha three times weekly, with or without amantadine (200 mg/day). HCV RNA-positive patients at 6 months discontinued treatment, and all others completed 12 months.
RESULTS:
At month 6, HCV RNA-negative patients made up 54.2% of the interferon + amantadine group and 42.0% of the monotherapy group (P = 0.07). At month 12, HCV RNA-negative patients made up 38.5% of the interferon + amantadine group and 28.4% of the monotherapy group (N.S.). The sustained virological response rates were 21.6% and 20.9%, respectively (N.S.).
CONCLUSION:
The addition of amantadine does not enhance the sustained virological response to interferon-alpha in naive patients with chronic hepatitis C; however, an additive effect of amantadine occurs in the first 6 months, mainly in patients without an early response to monotherapy. Early response to interferon-alpha is a strong predictor of sustained virological response
