Daptomycin treatment was well tolerated at a mean dose of 8 mg/kg for a median duration of 25 days. The incidence of symptomatic CPK level elevation was within the range reported with lower doses of daptomycin and/or for shorter treatment durations.
Daptomycin was well tolerated and effective at doses of 8 mg/kg or higher in patients with gram-positive infections. Further prospective and comparative studies of daptomycin at doses greater than 6 mg/kg are warranted.
Parenteral therapy for 72 hours followed by oral ciprofloxacin significantly shortened both the number of hospital days taking antibiotics and the length of stay compared with parenteral therapy alone. Both regimens were equally effective and safe in the therapy of gram-negative bacteremia, and initial parenteral therapy followed by oral ciprofloxacin was cost-effective.
The objective of this study was to determine if a lower rate of adherence (<95%) is sufficient to maintain HIV viral suppression in patients on an efavirenz-based regimen. This study was a retrospective review of pharmacy refill records at an HIV specialty pharmacy at Montefiore Medical Center's outpatient clinic. Data from 151 HIV-positive patients on an efavirenz-based regimen with at least one undetectable viral load (HIV RNA < 400 copies/mL) from December 2003 through March 2005 were reviewed. Adherence was calculated based on the formula: [(pills dispensed/pills prescribed per day/days between refills)x100%]. Calculated adherence for each time-period was correlated to the respective HIV-RNA value for that period. Of 151 patients, viral suppression was maintained in greater than 80% of time periods for adherence rates as low as 85-90%. The periods with 75-80% adherence also had higher than 85% suppression. Rates of suppression began to fall when adherence decreased to < 75%. In conclusion, lower adherence rates (<95%) on an efavirenz-based regimen were more successful in maintaining viral suppression than previously found with unboosted protease inhibitor-based regimens.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
