September 15, 2010 (Boston, Massachusetts) - Fidaxomicin is superior to vancomycin in treating recurrences of gastrointestinal Clostridium difficile infection, according to a blinded randomized trial presented here at the 50th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC). (medscape.com)
Now we know we can prevent recurrences after vancomycin with fidaxomicin. (medscape.com)
Patients were then randomized to receive either fidaxomicin or vancomycin. (medscape.com)
In both phase 3 trials, fidaxomicin was noninferior to oral vancomycin in preventing symptom recurrence within 30 days of completing 10 days of therapy. (medscape.com)
For 10 days, patients received oral fidaxomicin 200 mg twice daily or oral vancomycin 125 mg 4 times daily. (medscape.com)
Recurrences occurred later with fidaxomicin - on about day 17 compared with day 8 - for patients on vancomycin," Dr. Cornely said. (medscape.com)
Dr. Cornely believes that an explanation for the superiority of fidaxomicin in these studies is that the healthy flora protected against the re-emergence of C difficile in patients who received the newer drug, whereas persistent spores of the bacteria remained in the gut of patients who received vancomycin. (medscape.com)
He said that further study is needed to determine the putative connection between the differential effects of vancomycin and fidaxomicin on the bacterial environment of the gut and whether those differential effects are causally related to the clinical effects of these drugs. (medscape.com)

In two randomized, double-blind trials, a noninferiority design was utilized to demonstrate the efficacy of fidaxomicin (200 mg b.i.d. for 10 days) compared to vancomycin (125 mg four times daily for 10 days) in adults with CDAD. (clinicaladvisor.com)
Similar rates of clinical response at the end of treatment and proven or suspected CDAD during the follow-up period were seen in fidaxomicin-treated and vancomycin-treated patients infected with a BI isolate. (clinicaladvisor.com)
However, fidaxomicin did not demonstrate superiority in sustained clinical response when compared with vancomycin. (clinicaladvisor.com)
The second, published June 24 by the Infectious Diseases Society of America and Society for Healthcare Epidemiology of America , drives a shift in treatment for initial episodes and short-term recurrence from vancomycin to fidaxomicin and, in some cases, adding on the monoclonal antibody bezlotoxumab, both made by Merck. (the-hospitalist.org)
For an initial episode, the IDSA/SHEA authors conditionally recommend fidaxomicin as first preferred choice over vancomycin, with a moderate certainty of evidence. (the-hospitalist.org)
She told this news organization that the cost difference between fidaxomicin and vancomycin is considerable and finds the choice to foreground fidaxomicin puzzling. (the-hospitalist.org)
Dr. Fischer cited a ballpark of about $100 for a course of vancomycin, compared with about $3,000 for a course of fidaxomicin. (the-hospitalist.org)
According to Dr. Fischer, the ACG guidelines authors discussed fidaxomicin and concluded that there just wasn't enough evidence to justify favoring this antibiotic over vancomycin, given the cost-benefit imbalance. (the-hospitalist.org)
The ACG guidelines call for a standard course of oral vancomycin for a first, nonsevere C. difficile episode, listing oral fidaxomicin or oral metronidazole as alternatives. (the-hospitalist.org)
For a recurrence, the IDSA/SHEA authors also favor fidaxomicin in a conditional recommendation over a standard course of vancomycin. (the-hospitalist.org)
Dr. David Johnson said that these recommendations favoring fidaxomicin are "surprising," and that lower costs of vancomycin outweigh the benefit of fidaxomicin, given more-or-less comparable data on cure rates. (the-hospitalist.org)
Current first-line antibiotics include metronidazole, vancomycin, and fidaxomicin, with selection based on infection severity and other factors. (drugtopics.com)
And most guidelines currently recommend either vancomycin or fidaxomicin to be administered. (cdc.gov)
to vancomycin, you could for example be treated with fidaxomicin. (cdc.gov)
Which again, would be another class of drugs--probably less effective than vancomycin or fidaxomicin--but that would also be an option for someone with an allergy. (cdc.gov)
Infection15
The increasing emergence of vancomycin-resistant enterococci has resulted in the development of guidelines for use by the Centers for Disease Control Hospital Infection Control Practices Advisory Committee. (wikipedia.org)
in particular, in cases of relapse or where the infection is unresponsive to metronidazole treatment (for this indication, vancomycin is given orally, rather than by its typical intravenous route) For treatment of infections caused by Gram-positive microorganisms in patients with serious allergies to beta-lactam antimicrobials. (wikipedia.org)
Because the presence of leukocytosis and renal impairment are indicators of severe infection, patients with these findings should be treated initially with oral vancomycin instead of metronidazole. (medscape.com)
To engage the audience, Dr Slain began with 3 clinical questions that challenged the audience's ability to identify proper infection control procedures and differentiate between situations when vancomycin is preferential to metronidazole. (ajmc.com)
Since 1989, a rapid increase in the incidence of infection and colonization with vancomycin-resistant enterococci (VRE) has been reported by U.S. hospitals. (cdc.gov)
An increased risk for VRE infection and colonization has been associated with previous vancomycin and/or multiantimicrobial therapy, severe underlying disease or immunosuppression, and intraabdominal surgery. (cdc.gov)
This report presents recommendations of the Hospital Infection Control Practices Advisory Committee for preventing and controlling the spread of vancomycin resistance, with a special focus on VRE. (cdc.gov)
Traditional therapeutic options for treatment of C. difficile infection include metronidazole or vancomycin. (smw.ch)
Over 20 years, vancomycin has been the best drug for efficacy [in the treatment of C difficile infection. (medscape.com)
It may be as effective as vancomycin in treating initial infection, as well as in preventing recurrence. (medscape.com)

Vancomycin was the standard treatment for recurrent infection. (elis.sk)
Currently, few acceptable treatments for C. difficile are available, with vancomycin and metronidazole being linked to infection returning after treatment and to significant side effects. (europa.eu)
Clinical studies revealed that Dificlir is as effective as vancomycin in curing C. difficile infection and that the two medicines have similar rates of side effects, such as feeling sick, low blood potassium levels, headache, vomiting and stomach cramps. (europa.eu)
Antibiotics3
Vancomycin is indicated for the treatment of serious, life-threatening infections by Gram-positive (aerobic and/or anaerobic) bacteria unresponsive to other antibiotics. (wikipedia.org)
Prior to WMT, 48.1% of patients had been treated with metronidazole/ornidazole/tinidazole, 40.7% with vancomycin, and 7.4% with other antibiotics. (consultantlive.com)
Enterococci3
From 1989 through 1993, the percentage of nosocomial enterococcal infections reported to CDC's National Nosocomial Infections Surveillance (NNIS) system that were caused by vancomycin-resistant enterococci (VRE) increased from 0.3% to 7.9% (1). (cdc.gov)
Vancomycin resistance in enterococci has coincided with the increasing incidence of high-level enterococcal resistance to penicillin and aminoglycosides, thus presenting a challenge for physicians who treat patients who have infections caused by these microorganisms (1,4). (cdc.gov)
MRSA and vancomycin-resistant enterococci, and viridans are resistant to antimicrobacterial agents frequently used for prophylaxis and empiric treatment. (standardofcare.com)

Working with co-first author Bastiaan Haak, Harris initiated the 63-person study to include healthy male adults randomized into two arms of antibiotic treatment: either broad spectrum with vancomycin/ciprofloxacin/metronidazole, where all bacteria were essentially killed, or narrow-spectrum with vancomycin. (sciencedaily.com)
The first set, published June 1 by the American College of Gastroenterology , focuses on fecal microbiota transplantation (FMT) and the antibiotic vancomycin. (the-hospitalist.org)
Recurrences3
In both studies, DIFICID demonstrated a statistically significant reduction in the rate of recurrence compared with patients treated with vancomycin, reducing CDI recurrences by 47 percent, and was statistically superior to vancomycin in global cure rate (clinical cure without disease recurrence within four weeks). (prnewswire.com)
In contrast, the ACG guidelines recommend that an initial recurrence be treated with a tapering dose of vancomycin, and call for FMT for patients who are eligible and who experience a second or more C. difficile recurrences after a round of pulsed vancomycin. (the-hospitalist.org)
CDAD3
This randomized, placebo-controlled trial was the first trial comparing oral metronidazole and vancomycin in CDAD that was blinded and that stratified patients by disease severity. (medicine52in52.com)
At the time of publication of this study (2007), the CDC was not recommending vancomycin as first-line therapy for CDAD (for fear of spread of VRE). (medicine52in52.com)
Following this study, the 2010 update to the IDSA/SHEA guidelines for the treatment of CDAD recommended metronidazole PO for the initial treatment of mild-to-moderate CDAD, vancomycin 125mg PO QID for the initial treatment of severe CDAD, and vancomycin + metronidazole IV for severe, complicated CDAD. (medicine52in52.com)
Severe7
This trial, initiated in 1994, sought to investigate whether metronidazole PO or vancomycin PO was the superior initial treatment strategy in both mild and more severe disease. (medicine52in52.com)
Among patients with severe disease, 29 of 38 (76%) metronidazole patients were cured and 69 of 71 (97%) vancomycin patients were cured (p = 0.02). (medicine52in52.com)
Among patients with severe disease, 6 of 29 (21%) of metronidazole patients relapsed and 3 of 30 (10%) of vancomycin patients relapsed (p = 0.30). (medicine52in52.com)
The authors hypothesize that "a potential mechanism for our observation that metronidazole performs less well in patients with severe disease is that the drug is delivered from the bloodstream through the inflamed colonic mucosa, and stool concentrations decrease as disease resolves. (medicine52in52.com)
Severe disease or re-peated relapses are managed better with vancomycin. (bcmj.org)
Bacteria3
vancomycin does not cure the patient and success is limited Treatment of endophthalmitis by intravitreal injection for gram-positive bacteria coverage. (wikipedia.org)
Vancomycin is considered a last resort medication for the treatment of sepsis and lower respiratory tract, skin, and bone infections caused by Gram-positive bacteria. (wikipedia.org)
Eighty-four percent of CDI cases were treated, with vancomycin being the most common treatment given. (cdc.gov)
These multi-center, randomized, double-blind trials enrolled a total of 1,164 adults with confirmed CDI, who received either DIFICID (200 mg q12h) or vancomycin (125 mg q6h), the only FDA-approved product for the treatment of CDI. (prnewswire.com)
The objective of both studies was to show that a 10-day course of DIFICID was at least as efficacious (non-inferior) and safe as a 10-day course of vancomycin for the treatment of CDI. (prnewswire.com)
DIFICID was safe and well tolerated in both studies, showing a similar incidence of treatment-related adverse events when compared to vancomycin. (prnewswire.com)
In contrast, vancomycin, which is approved for this indication, and metronidazole, which is often used as treatment, suppress the growth of normal endogenous flora. (medscape.com)

He was discharged and given oral doxycycline, ciprofloxacin, and metronidazole treatment because of history of penicillin allergy. (cdc.gov)
Antimicrobial drug susceptibility to metronidazole, clindamycin, levofloxacin, and vancomycin was determined for all isolates by using the E-test method (AB Biodisk, Solna, Sweden) on Mueller-Hinton agar ( 12 ). (cdc.gov)
Isolates2
Complicated skin and skin structure infections caused by Escherichia coli, Enterococcus faecalis (vancomycin-susceptible isolates only), Staphylococcus aureus (methicillin-susceptible and ‑resistant isolates), Streptococcus agalactiae, Streptococcus anginosus grp. (druglib.com)
In Phase 3 clinical studies, DIFICID was proven to be as effective as vancomycin in clinical cure, and was superior to vancomycin in global cure, defined as cure without a recurrence after 4 weeks of therapy. (prnewswire.com)
While the advisory committee vote was split on how best to describe the recurrence benefit, the committee members overwhelmingly recognized that DIFICID at 30 days was superior to vancomycin. (prnewswire.com)
DIFICID1
In addition, DIFICID met the primary endpoint of non-inferiority of clinical cure (defined as patients requiring no further CDI therapy two days after completion of study medication) compared to vancomycin. (prnewswire.com)
Therapeutic options1
therefore, this option should be reserved for patients in whom other therapeutic options, including metronidazole and vancomycin, have failed. (druglib.com)
Therapy1
This increase poses important problems, including a) the lack of available antimicrobial therapy for VRE infections, because most VRE are also resistant to drugs previously used to treat such infections (e.g., aminoglycosides and ampicillin), and b) the possibility that the vancomycin-resistant genes present in VRE can be transferred to other gram-positive microorganisms (e.g. (cdc.gov)
Among patients with mild disease, 37 of 41 (90%) metronidazole patients were cured and 39 of 40 (98%) vancomycin patients were cured (p = 0.36). (medicine52in52.com)
Later trials using purer forms of vancomycin found nephrotoxicity is an infrequent adverse effect (0.1% to 1% of patients), but this is accentuated in the presence of aminoglycosides. (wikipedia.org)
BACKGROUND: To compare the monotherapy of tigecycline with vancomycin-aztreonam in hospitalized patients from India and Taiwan with complicated skin and skin structure infections (cSSSIs). (druglib.com)
The actual increase in the incidence of VRE in U.S. hospitals might be greater than reported because the fully automated methods used in many clinical laboratories cannot consistently detect vancomycin resistance, especially moderate vancomycin resistance (as manifested in the VanB phenotype) (9-11). (cdc.gov)
Clinical trials2
Damage to the kidneys (nephrotoxicity) and to the hearing (ototoxicity) were side effects of the early impure versions of vancomycin, and these were prominent in the clinical trials conducted in the mid-1950s. (wikipedia.org)
The AIDAC based its decision in part on the review of clinical evidence from the two largest, comparative Phase 3 clinical trials ever conducted against vancomycin in CDI. (prnewswire.com)
